Description

CROSS-REFERENCE OF RELATED APPLICATION

The present invention claims priorities of Chinese Patent Application No. 202411245190.3, filed on Sep. 5, 2024, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The disclosure relates to the technical field of sexual products and the technology for realizing bidirectional stimulation, and particularly relates to a bidirectional stimulation massage device.

BACKGROUND

In recent years, as people pay increasing attention to the quality of intimate relationships and experience, a wide range of innovative adult products have gradually came on the market. However, although these products are designed to improve the quality of intimate relationships and meet personalized needs, the existing adult products still have significant deficiencies in both technical design and user experience, which restrict their functions and market expansion.

At present, most of the adult products available on the market are usually designed for a single gender or a single object. For example, vibrating massagers are often designed for women, and mainly focus on stimulating sensitive areas through vibrations or other mechanical actions to help women achieve greater sexual satisfaction. However, the applicability of these products to men is relatively constrained, as they cannot provide same degrees of experience and satisfaction for male users. Similarly, adult products specifically designed for men, such as self-satisfaction devices, cannot provide any good experience for women. The single design severely limits applicable scopes of these products, resulting in a lack of interactive and synchronized experience between a couple or sexual partners when these products are used.

Furthermore, many of the adult products are designed to focus on unidirectional stimulation, ignoring the importance of interaction between sexual partners. In an intimate relationship, the interaction and emotional communication between the sexual partners are crucial for enhancing the relationship. However, the existing products usually provide stimulation only for one of the sexual partners, while the other sexual partner lacks corresponding physiological feedback, thereby being difficult to form good interactive experience. The design is not enough to meet the needs of both of the sexual partners for joint use, affecting the effects of intimate experience.

In addition, some adult products are designed primarily for invasive stimulation, such as plug-in massagers or dilators, which may provide strong physiological stimulation. Nevertheless, these products are usually suitable for only one gender and cannot simultaneously satisfy both of the sexual partners, thus affecting the harmony and overall experience of the interaction between the sexual partners.

The current design of many products is unable to satisfy the needs of both of the sexual partners, resulting in a less desirable experience. The sexual partners have to use their respective products separately, making the operation complicated and inconvenient, which affects the smoothness and overall satisfaction of the sexual experience. Furthermore, a single-object design also ignores the emotional communication and synchronized experience that the sexual partners often seek during intimate interactions, further limiting the market acceptance and applicable scopes of these products.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The technical solutions of embodiments of the present invention will be described below clearly and comprehensively in conjunction with accompanying drawings of the embodiments of the present invention. Apparently, the embodiments described are merely some embodiments rather than all embodiments of the present invention. All the other embodiments obtained by those of ordinary skill in the art based on the embodiments in the disclosure without creative efforts shall fall within the scope of protection of the disclosure.

With reference to FIGS. 1-47, specific embodiments provided by the disclosure are as follows:

• • as shown in FIGS. 1-2, a first embodiment of the disclosure provides a bidirectional stimulation massage device, including:
  • a thin-walled structure 1 having a channel 2, where the thin-walled structure 1 has a set length L in an axial direction; and
  • the set length L is not less than 4 cm;
  • the thin-walled structure 1 has an inner wall 101 and an outer wall 102;
  • a first stimulation device 3;
  • where the first stimulation device 3 is arranged in a position at a non-end portion of the thin-walled structure 1; and
  • the first stimulation device 3 is configured to be located between the inner wall 101 and the outer wall 102, and is capable of providing massage stimulation to both the inner wall 101 and the outer wall 102 at the same time.

In this embodiment, the channel 2 is used for facilitating a penis being sheathed in, such that the inner wall 101 of the thin-walled structure 1 is in contact with a surface of the penis, and the outer wall 102 is in contact with an inner wall of a vagina.

Specifically, the channel 2 is provided with at least one first opening 203, the penis is inserted into the channel 2 through the first opening 203 to complete the wearing, and after the wearing is completed, a male can insert both the penis and the thin-walled structure 1 into the female vagina.

In another specific embodiment, the channel 2 is further provided with a second opening 204, and the first opening 203 and the second opening 204 are openings at two ends of the channel 2 in an axial direction, such that the thin-walled structure 1 forms a structure that passes through the channel 2.

Alternatively, in another specific embodiment, the channel 2 has only one first opening 203, and the other end of the channel 2 is a closed structure.

Specifically, a thickness of the thin-walled structure 1 ranges from 2 mm to 6 mm.

Specifically, a reason for setting the set length L of the thin-walled structure 1 is to ensure simultaneous massage stimulation of both the penis and the inner wall of the vagina. By setting the length L of the thin-walled structure 1 to not less than 4 cm, it is ensured that the massage device is capable of covering an effective length of the penis, such that the first stimulation device 3 is in an optimal position to apply massage stimulation to both the inner wall 101 and the outer wall 102 of the thin-walled structure 1, thereby providing effective stimulation to both the surface of the penis and the inner wall of the vagina.

More specifically, by setting the length L, the inner wall 101 of the thin-walled structure 1 is capable of fitting closely to the surface of the penis when the massage device is in normal use, ensuring that the first stimulation device 3 in the position of the non-end portion the thin-walled structure 1 is in close contact with a specific part of the penis. In addition, the outer wall 102 of the thin-walled structure 1 is in contact with the inner wall of the vagina, through the bidirectional pressure distribution and friction effect, the first stimulation device 3 is capable of stimulating both the penis and the inner wall of the vagina simultaneously during each process of insertion and withdrawal.

• • this design of the length not only considers an average size of the penis to ensure that the first stimulation device 3 is capable of covering main sensitive areas of the penis, but also ensures that the massage device is not easy to slide or shift when in use, such that continuous and stable stimulation can be provided. Setting the length L to be not less than 4 cm can also prevent insufficient or uneven stimulation caused by the massage device being too short, and prevent discomfort or inconvenience caused by the massage device being too long. Therefore, determination of the length range aims to optimize comfort of a user and functionality of the massage device, ensuring the maximization of bidirectional stimulation effects.

Addition of the first stimulation device 3 aims to enhance the functionality and stimulation effects of the massage device in sexual activity by introducing an additional mechanical action structure (which can be either a powered or non-powered mechanical structure). Specifically, the first stimulation device 3 is designed for solving the problem that the ordinary thin-walled structure 1 is difficult to provide sufficient and even stimulation, especially when the inner wall 101 is in contact with the penis, and the outer wall 102 is in contact with the inner wall of the vagina.

The first stimulation device 3 is arranged in the position of the non-end portion of the thin-walled structure 1, such that it is capable of focusing on the specific part of the penis and sensitive areas of the inner wall of the vagina for concentrated stimulation. When in use, the traditional thin-walled structure 1 mainly relies on the elasticity of a thin wall to produce a certain degree of friction and compression effect. However, intensity and range created by this passive stimulation are usually insufficient and may not meet the needs of the user for stronger or more continuous stimulation.

The introduction of the first stimulation device 3 can effectively enhance massage stimulation sensation of the massage device during use by actively applying pressure and generating friction, and produce a targeted massage effect through structural design, which cannot only achieve a stronger bidirectional stimulation effect by increasing friction coefficient and pressure distribution, thereby providing better use effects and pleasure response.

The bidirectional stimulation massage device in this embodiment can provide richer and stronger sensory experience through the action of the first stimulation device 3 on the basis of achieving simultaneous stimulation to both the penis and the inner wall of the vagina, thereby meeting higher requirements of the user for functionality and experience effect of the massage device.

In addition, the addition of the first stimulation device 3 is not only to improve basic functionality of the massage device, but also to achieve a highly personalized and creative user experience in specific application scenarios, this design takes into account complete needs in real use environments, and aims to address the limitations of traditional massage devices in meeting diverse needs of different users.

In specific application scenarios, such as intimate interactions between a couple, the user often seeks a device capable of providing deeper satisfaction on multiple sensory levels. The traditional thin-walled structure 1 can only provide passive friction in a single one direction, the massage device can apply pressure and friction in an active or passive manner by introducing the first stimulation device 3, which not only provides stronger physical stimulation, but also enhances psychological excitement and satisfaction of the user Further, the first stimulation device 3 can facilitate the bidirectional stimulation massage according to actions of the user, such as pushing, pulling, or rotating, this feedback mechanism enables the massage device to enhance the stimulation effect during use, and provides richer experience changes for the user. Especially, during the use in a prolonged period of time, this dynamic response ability can prevent fatigue caused by unidirectional stimulation, making the user enjoy continuous pleasure. The bidirectional stimulation is not only limited to a physical level, but also enhances emotional connection and interactive enjoyment between the couple by acting on key sexual parts of the couple at the same time.

In summary, the addition of the first stimulation device 3 is not merely a structural improvement of the massage device, but aims to create more personalized, dynamic, and interactive experience in specific application scenarios, and the creative design breaks the limitations of traditional massage devices and provides a higher level of satisfaction.

As shown in FIG. 47, in another specific embodiment, a stimulation structure 16 is formed on the outer wall 102 of the thin-walled structure. The stimulation structure 16 is configured to generate stronger stimulation sensation to the inner wall of the vagina, stimulation structure 16 can be a plurality of spherical protrusions, or a plurality of annular protrusions or semi-annular protrusions arranged in the axial direction of the thin-walled structure 1, in which case, the outer wall 102 is in the form of a corrugated surface.

As shown in FIGS. 1 and 2, in one specific embodiment, the channel 2 is a continuous channel structure formed by a circumferential wall surface of the thin-walled structure 1. The continuous channel structure is a complete continuous annular wall structure of the channel 2 without any gaps in the circumferential wall surface of the thin-walled structure.

One of the manifestations is that the thin-walled structure 1 is a sleeve structure, and thin-walled structure 1 has the complete circumferential wall surface.

As shown in FIGS. 19-21, in another specific embodiment, the channel 2 is a non-continuous channel structure formed by the circumferential wall surface of the thin-walled structure 1. The non-continuous channel structure has a gap or notch 201 in a specific position on a circumferential wall surface of the channel 2.

One of the manifestations is that the thin-walled structure 1 is provided with a plurality of regularly spaced longitudinal openings or slits in specific positions on the circumferential wall surface. The plurality of openings or slits can generate additional flexibility and deformability when the massage device is used, allowing the channel 2 to expand or contract properly under external force, thereby increase local stimulation effect on the penis and the inner wall of the vagina, this design not only improves the fit of the massage device, but also provides more complex and diverse sensory experience through periodic changes of the gap or notch 201, adapting to use habits and preferences of different users.

As shown in FIGS. 16-18, the other manifestation is that the thin-walled structure 1 is provided with a plurality of staggered regular or irregular mesh structures 202 (such as a spider web-like design) in the specific positions on the circumferential wall surface, the mesh structures 202 form a plurality of staggered grids on the thin-walled structure 1, such that the channel 2 has greater elasticity and breathability in a specific area, this design can provide unique tactile stimulation during use; when the thin-walled structure 1 is subjected to external force, the mesh portion can be locally deformed and produce a massage effect different from that of the continuous wall surface. In addition, the mesh structures 202 can enhance the stability of the massage device in some cases, preventing slipping during use, and providing richer sensory experience through irregular tactile sensations.

A second embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the first embodiment, the first stimulation device 3 includes:

• • an electric stimulation assembly having an electric drive module 301 and a mechanical vibration module 302;
  • where the electric drive module 301 is composed of one or more of a rotary motor 3016, a linear motor 3014, and an electromagnetic attraction unit, as well as a battery, a drive circuit, and a control circuit;
  • the mechanical vibration module 302 is connected to one or more of the rotary motor 3016, the linear motor 3014, and the electromagnetic attraction unit, and responds to motion generated by the electric drive module 301 to output mechanical vibrations externally.

In this embodiment, the first stimulation device 3 adopts an active electrical stimulation form, specifically, the stimulation experience is created in a form of electrical energy drive.

As shown in FIGS. 24 and 25, in one specific form, the electric drive module 301 is a rotating motor 3011, and the mechanical vibration module 302 is an eccentric wheel 3021 or an eccentric block. The rotating motor 3011 is connected to a power source to obtain electrical energy and drives the eccentric wheel 3021 or the eccentric block that is connected to a drive end of the rotating motor 3011 to produce vibration massage stimulation effects.

As shown in FIGS. 26 and 27, in another specific form, the electric drive module 301 adopts a combination of an electromagnet 3012 and the control circuit, the mechanical vibration module 302 is usually composed of components capable of giving response to changes in an electromagnetic field, such as a metal sheet 3022, an elastic diaphragm or a transmission rod. By periodically switching a direction of current or adjusting an intensity of the current, a pulsed electromagnetic field is generated. The electromagnetic field drives the mechanical vibration module 302 to generate rapid pulse vibrations or push-pull motion, thereby producing an electromagnetic pulsed stimulation effect at a massage site, which is particularly suitable for massage applications requiring high-frequency vibrations with relatively small amplitudes.

As shown in FIG. 28, in another specific form, the electric drive module 301 of the first stimulation device 3 is an ultrasonic vibrator 3013, the ultrasonic vibrator 3013 converts the electrical energy into high-frequency vibration waves to generate ultrasonic vibrations, which are then transmitted to the mechanical vibration module 302, and the mechanical vibration module can be an ultrasonic probe 3023 or other components capable of conducting ultrasonic waves; and when being transmitted to a massage area, the ultrasonic vibrations can penetrate surface tissue, providing deep micro-vibration massage, which is particularly suitable for physical therapy and massage of deep tissue.

Of course, in addition to generating vibrations or similar vibration-like massage effects, the first stimulation device 3 can also adopts the following massage forms:

For example, the first stimulation device 3 can produce scraping sensation, or a sliding or rolling massage effect.

Specifically, the electric drive module 301 can be:

• • as shown in FIGS. 29 and 30, a stepper motor 3014 can be used as the electric drive module 301, and can precisely control a moving distance and a speed of the mechanical vibration module 302. Specifically, by driving a sliding sheet 3024 having toothed edges or textures, the stepper motor 3014 is capable of producing scraping sensation on the massage area, the scraping sensation can simulate the effect of fingers or a scraping plate scrapping on skin, and is suitable for promoting local blood circulation and relaxing muscles.

As shown in FIGS. 31 and 32, alternatively, the rotary motor 3016 can drive a set of rolling bearings 3026 or rollers to perform rolling motion, the rolling bearings 3026 can be designed to have an irregular surfaces or protrusions, thereby producing rolling and scraping effects on the massage area as driven by the rotary motor 3016. The rolling massage cannot only provide deep stimulation, but also produce continuous scraping sensation, which is suitable for massage applications requiring enhanced local stimulation.

By introducing the electric drive modules 301, the first stimulation device 3 can provide various massage forms, such as sliding or rolling scraping sensation. The massage forms can simulate the traditional massage techniques such as scrapping, rolling, or shiatsu, effectively promoting local blood circulation, relaxing tense muscles, and enhancing physiotherapy effects. The electric drive modules 301 having different powers allow precise control over intensity, speed, and frequency of scraping or rolling, thereby achieving personalized massage experience.

In addition, the first stimulation device 3 further includes:

• • a driven stimulation assembly having displacement modules 303 and driven mechanical modules 304.

In this form, the driven mechanical modules 304 are capable of producing massage stimulation effects in cooperation with thrusting actions through the displacement modules 303.

As shown in FIGS. 34 and 35, for example, the displacement modules 303 are slide rods 3031, and the driven mechanism modules 304 are one or more of spheres 3041 slidably connected to the slide rods 3031. Each of the spheres 3041 is capable of sliding freely on tracks of the slide rods 3031, and produce continuous physical stimulation with the thrusting actions, similar to rolling massage effects.

The spheres 3041 can be made from various materials, such as silicone, plastic, or metal, to provide different tactile sensations and massage intensities. Size and shape of the spheres 3041 can also be adjusted as needed to meet different massage requirements.

As shown in FIGS. 36 and 37, for example, a cavity 3032 is formed between the inner wall 101 and the outer wall 102, one or more stimulation balls 3042 are placed inside the cavity 3032, each of the stimulation balls 3042 is capable of rolling or sliding freely inside the cavity 3032, thereby producing continuous physical stimulation with the thrusting motions.

In either specific form mentioned above, the mechanical vibration module 302 or the driven mechanism modules 304 are designed to provide massage stimulation to both the inner wall 101 and the outer wall 102 simultaneously, thereby achieving synchronized stimulation for both sexual partners, this design significantly differs from the massage apparatuses in the prior art that is usually only for a single object (such as male or female), and has the following important features:

During operation, the mechanical vibration module 302 or the driven mechanism modules 304 can apply massage stimulation to both the inner wall 101 (male reproductive organs) and the outer wall 102 (female reproductive organs) simultaneously, the bidirectional stimulation design enables the massage device to provide physiological pleasure and physiotherapy effects for both sexual partners during use, thereby enhancing interactive experience between them.

The mechanical vibration module 302 or the driven mechanism modules 304 can produce various stimulation in different directions, regardless of in the form of vibration, sliding, or rolling motion. For the male, the stimulation of the inner wall 101 can act on the surface of the penis; for the female, the stimulation of the outer wall 102 can act on the inner wall of the vagina and a vulva, the multi-dimensional massage effects enable both sexual partners to receive continuous and rich sensory experience when the massage device is used.

By providing synchronized massage stimulation for both the male and the female, this design of the massage device is conducive to enhancing intimate interaction between both sexual partners. Since both sexual partners can simultaneously feel the stimulation from the massage device, they can enjoy synchronized pleasure and satisfaction, thereby enhancing emotional connection and understanding.

Most of the reproductive health massage devices in the prior art are usually designed for only one object, for example, providing massage stimulation only for the male or female reproductive organs, which impose great limitations on the use experience. In contrast, the disclosure benefits both sexual partners simultaneously by acting on both the inner wall 101 and the outer wall 102, greatly improving the practicality and market application potential of the massage device.

Through the above design, the first stimulation device 3 of the disclosure can effectively overcome the shortcomings of the prior art, and provide the user with more comprehensive and balanced massage experience, the synchronized bidirectional stimulation sensation not only improves the use effects, but also brings greater satisfaction to the user, meeting the needs of modern society for sexual harmony and reproductive health.

As shown in FIG. 38, a third embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, the inner wall 101 of the thin-walled structure 1 is provided with an ejaculating compression and control area 4.

In this embodiment, the ejaculating compression and control area 4 is designed and intended to provide more precise physiological control and physiotherapy effects. The ejaculating compression and control area 4 is arranged on the inner wall 101 of the thin-walled structure 1, and has a length L2 in the axial direction of the thin-walled structure being not less than 2 cm. By increasing local pressure in the specific area, the ejaculating compression and control area can apply moderate compression on the penis of a wearer, achieving an ejaculating control function.

A main function of the ejaculating compression and control area 4 is to control ejaculating time by applying moderate compression to the penis during wear, which can prolong duration of sexual activity, help improve sexual function, and enhance physiological experience. In addition, moderate pressure can increase blood flow to the penis, thereby enhancing hardness of erection and improving the quality of sexual life.

In this embodiment, the ejaculating compression and control area 4 is precisely designed to provide a sufficient compression area in the axial length while ensuring uniform distribution of pressure, which cannot only effectively control the ejaculating time but also avoid discomfort caused by excessive pressure, such that the user can maintain comfort while enhancing the experience.

On the basis of the previous embodiment, this embodiment combines bidirectional stimulation with the ejaculating control function, which means that, in addition to providing bidirectional massage stimulation for the inner wall 101 and outer wall 102, the massage device can provide the user with physiological control function through the ejaculating compression and control area 4, This combination greatly improves the versatility of the massage device, making it suitable not only for daily reproductive health massage but also for improving sexual dysfunction.

Further, the setting of the ejaculating compression and control area 4 is conducive to prolonging the duration of sexual activity, which is an ideal solution for some users with premature ejaculation problem. In addition, the massage device can enhance physiological pleasure and intimate interaction of the sexual partners during sexual activity through moderate compression.

The massage device is not only suitable for daily reproductive health maintenance, and also is used for treating sexual dysfunction, particularly premature ejaculation and erectile dysfunction. The user can choose whether to enable the compression and ejaculating control function according to actual needs, so as to flexibly response to different application scenarios.

In summary, on the basis of the previous embodiment, this embodiment further improves the functionality and use effects of the bidirectional stimulation massage device by introducing the ejaculating compression and control area 4, this design not only meets the needs of users for enhanced physiological experience but also provide more personalized physiotherapy options, bringing the user more comprehensive and comfortable experience.

As shown in FIG. 39, in one specific embodiment, the ejaculating compression and control area 4 is configured for local compression. Specifically, this ejaculating compression and control area 4 is capable of realizing precise compression to the specific part of the penis by setting local protrusions 401 or a thickened structures in specific positions of the inner wall 101, so as to achieve ejaculating control effects.

The ejaculating compression and control area 4 can be implemented by incorporating one or more of the local protrusions 401 on the inner wall 101. The local protrusions 401 can be made from flexible materials and have various shapes such as strips, points, or rings. Height and flexibility of the local protrusions 401 are carefully designed to provide sufficient pressure to achieve the function of ejaculating control without compromising overall wearing comfort.

The local protrusions 401 are usually arranged in an area corresponding to a vas deferens of the penis to ensure that pressure can be applied to key parts during wearing, thereby delaying the ejaculating time and enhancing control over sexual intercourse.

Another way to achieve local compression is to introduce a thickened inner wall inside the ejaculating compression and control area 4, the thickened structure can be implemented by increasing a thickness of the inner wall material or using material with higher hardness, this design is capable of providing uniform compression over a larger area, and is suitable for application scenarios requiring a large area of ejaculating control.

Length and position of the thickened area are also precisely defined to ensure that adequate and stable compression can be provided during use while avoiding discomfort or damage to other parts of the penis.

In another form of local compression, the ejaculating compression and control area 4 becomes prominent only when the thin-walled structure 1 deforms, that is, when the massage device is worn. Specifically, when the massage device is in a natural unworn state, the local protrusions in the ejaculating compression and control area 4 appear as a smooth inner wall without any obvious protrusion structure, this design ensures the flatness and portability of the thin-walled structure 1 when not in use, avoiding inconvenience caused by the protrusion structure to the operation and storage in the unworn state.

When the thin-walled structure 1 is worn on the penis, the ejaculating compression and control area 4 automatically forms protrusions due to external pressure or a responsive mechanism of smart materials. The protrusions can be in close contact with the specific part of the penis, providing locally enhanced compression effects, and this design ensures that compression is generated only during use, thus avoiding unnecessary pressure or stimulation.

It should be noted that the protrusions are not conventional protrusions relative to a flat surface but are protrusions relatives to a curved surface of the inner wall 101. In other words, the protrusions are based on the curved surface of the inner wall 101, such that the protrusions can fit more naturally with contours of the penis. When being worn, the protrusions form a larger contact area with the surface of the penis, thereby providing a uniform and stable sense of compression.

For example, the ejaculating compression and control area 4 on the inner wall 101 can be made from highly elastic materials. In the unworn state of the thin-walled structure 1, this area appears to be flush with other parts. However, when the thin-walled structure 1 is worn, this elastic area deforms and forms the local protrusions 401 due to the pressure and external force from the penis, thereby the sense of compression, this design can automatically adapt to the shape and pressure of the penis during wearing, ensuring that the ejaculating compression and control area 4 is in close contact with the surface of the penis, providing precise ejaculating control effects.

Another implementation mode is to make use of shape memory materials, which can return to a preset shape when exposed to heat or subjected to mechanical stimulation. When being worn, the ejaculating compression and control area 4 deforms and highlights the compression structure due to body heat or friction, thereby providing a local sense of compression.

This design cannot only provide the ejaculating control function but also ensure that the thin-walled structure 1 retains its original shape when not in use, thereby improving the wearing comfort and portability.

As shown in FIG. 40, in order to meet the needs of different users, the local compression from the ejaculating compression and control area 4 can be designed to be adjustable. For example, an inflatable bag 402 or an adjustable mechanical structure is arranged on the inner wall 101, such that the user can adjust the compression intensity according to the personalized comfort and ejaculating control needs, this design offers greater flexibility and can meet the personalized needs of different users.

Through local compression, the ejaculating compression and control area 4 can apply precise pressure to the specific part of the penis, effectively delaying the ejaculating time, this design is particularly suitable for the users with premature ejaculation problem, helping them gain better control during sexual intercourse.

By applying moderate pressure to a key area of the penis, the local compression design can avoid the discomfort that may be caused by full-range compression. The user can become more comfortable in wearing while enjoying enhanced ejaculating control.

An adjustable local compression function further improves the user experience, enabling the user to flexibly adjust the compression intensity according to their respective individual needs and application scenarios, this personalized design can meet diverse needs of different users, and increase the applicability and satisfaction of the massage device.

The local compression design is not only suitable for daily reproductive health maintenance, but also particularly suitable for treating sexual dysfunction, such as premature ejaculation. The user can gradually improve sexual function and overall sexual health by adjusting compression zone and intensity.

In summary, this embodiment provides more precise and comfortable ejaculating control effects by incorporating the ejaculating compression and control area 4 capable of applying local compression, this design not only effectively prolong a duration of sexual intercourse but also improves the overall user experience of the massage device, making the device become a powerful and user-friendly reproductive health therapy device.

In one specific embodiment, the ejaculating compression and control area 4 is configured as fully-wrapped compression. Specifically, the fully-wrapped compression design is capable of performing wrapped compression to a specific part of the penis (such as a base section or a middle section) from all directions by arranging an annular structure or a thickened area in a specific area of the inner wall 101, thereby producing more uniform and stable ejaculating control effects.

The ejaculating compression and control area 4 can adopt an annular structure, and the penis is completely encircled by the annular structure on the inner wall 101 in a circumferential direction. When being worn, the annular structure applies uniform pressure to the surface of the penis through the thickened inner wall 101 or embedded elastic material, thereby achieving fully-wrapped compression, this design can ensure that each point in the compression zone is subjected to equal pressure, effectively controlling the ejaculating time. Material of the annular compression structure can be selected from silicone or highly elastic polymer to provide excellent flexibility and comfort.

Another fully-wrapped compression design is to arrange a plurality of sections of thickened areas in a specific axial area of the thin-walled structure 1, the thickened areas are capable of applying pressure to various parts of the penis simultaneously, thereby achieving a wider range of ejaculating control effects. Thickness and hardness of each section of the thickened areas can be independently to meet different compression needs, the plurality of sections of thickened areas can provide a larger compression zone without increasing the overall thickness, thereby enhancing the stability and comfort of the ejaculating control effects.

As shown in FIG. 42, the fully-wrapped compression can also be implemented via an embedded airbag 404, the embedded airbag 404 is distributed in the circumferential direction of the inner wall 101, and can be inflated or automatically expanded to achieve fully-wrapped compression to the penis when the massage device is worn. The user can adjust the pressure of the embedded airbag 404 to control the compression intensity, this design offers highly adjustable ejaculating control effects, thereby being adapted to different physiological conditions and application scenarios. The embedded airbag 404 is usually made from pressure-resistant and soft material, such as medical-grade silicone to ensure safety and comfort.

As shown in FIG. 41, regarding a more complex design, the fully-wrapped compression zone can adopt a spiral compression structure. The spiral thickened areas are arranged on the inner wall 101 in a spiral pattern, forming a compression zone similar to a spiral band 403. When the massage device is worn, the spiral compression zone can provide a gradually increasing pressure, forming continuous compression effects from a base to a tip of the penis, thereby enhancing ejaculating control effect, this design cannot only control the ejaculating time but also improve erection hardness and duration of the penis during sexual intercourse.

The design of fully-wrapped compression ensures uniform pressure across the entire compression zone, avoiding discomfort or excessive stimulation that may result from local compression. By wrapping the penis in all directions, the design can ensure the stability of ejaculating control effects, and prolong the duration of sexual intercourse.

The massage device can provide the fully-wrapped compression, the user can achieve better ejaculating control effects, and enhance the erection hardness of the penis, thereby improving overall sexual experience. this design is particularly suitable for users who need strong ejaculating control effects, and can also treat sexual dysfunction.

The design of fully-wrapped compression is highly adaptable, allowing for adjustments based on physiological characteristics and needs of different users. For example, the user can customize compression intensity and range to achieve personalized physiotherapy effects by adjusting a pressure of the embedded airbag 404 or selecting different materials.

In summary, the design of fully-wrapped compression in this embodiment provides stronger ejaculating control effects and more comfortable user experience for the bidirectional stimulation massage device. By fully wrapping and applying pressure to the penis evenly, the massage device can significantly improve physiological control and sexual function, making the device become a powerful and widely adaptable reproductive health physiotherapy device.

Of course, the arrangement of the ejaculating compression and control area 4 further overcomes the difficulty in determining a diameter of the thin-walled structure 1.

When the diameter of the thin-walled structure 1 is too small, it is very difficult for the user to wear the massage device, despite that sufficient compression force can be provided to improve the ejaculating control effects. A too small diameter will make the massage device very difficult to be worn, increasing the difficulty for wearing by the user, or even causing discomfort or friction injuries.

On the contrary, when the diameter of the thin-walled structure 1 is too large, the massage device will be easily to be worn and comfortable, but it will not provide the necessary compression, resulting in unsatisfactory ejaculating control effects. A too large diameter could lead to instability of the thin-walled structure 1 during use, affecting overall massage and physiotherapy effects.

By incorporating the ejaculating compression and control area 4, the disclosure skillfully balances the contradiction between a diameter size and compression effects. When the massage device is worn, the ejaculating compression and control area 4 can provide local or fully-wrapped compression, thereby achieving effective compression, regardless of the diameter of the thin-walled structure 1. The ejaculating compression and control area 4 allows for a more comfortable diameter of the thin-walled structure 1, such that the user can wear the massage device easier without significant concerns about difficulty during use. In addition, the ejaculating compression and control area adjusts automatically to form required compression force, thereby producing good ejaculating control effects. Various structural forms of the ejaculating compression and control area 4 (such as the annular structure, the thickened areas, and the airbag structure) make the massage device highly adaptable. Desired compression effects can be achieved in spite of slightly different diameters, this design cannot only improve convenience of use, but also ensure effective ejaculating control function.

The user can choose personalized compression structure according to his personal needs, such as the adjustable embedded airbag or elastic material, to precisely control compression strength, such that the diameter of the thin-walled structure 1 can be flexibly adapted even in different application scenarios, and good compression effects can be produced. The flexibility not only improves user experience but also broadens the practical application range of the massage device.

Through intelligent design of the ejaculating compression and control area 4, the disclosure solves the problems caused by the thin-walled structure 1 being too large or too small in the diameter, achieving an optimal balance between wearing convenience and compression effects. This design ensures that the user can easily wear the massage device, while achieving sufficient ejaculating control effects, such that the functionality and user experience of the massage device are significantly improved.

As shown in FIG. 43, a fourth embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, the ejaculating compression and control area 4 on the inner wall 101 is provided with a ridge-like protrusion 405;

• • the ridge-like protrusion 405 is configured to provide local compression to an area where the penis being in contact with the ridge-like protrusion 405; and
  • where a pressure P1 generated by the local compression is greater than an average pressure P0 applied by the thin-walled structure 1 to the penis that wears the massage device.

In this embodiment, the ejaculating compression and control area 4 of the inner wall 101 is provided with the ridge-like protrusion 405 to produce more precise and effective local compression. The ejaculating compression and control area 4 is provided with one or more of the ridge-like protrusion 405, which extend along the inner wall 101 and are usually designed to match an anatomical structure of the penis, so as to ensure that the ridge-like protrusion can be in precise contact with and apply compression to the key area of the penis, such as the vas deferens or a main nerve area of the penis, when the massage device is worn.

The design of the ridge-like protrusion 405 enables the same to provide significant local compression to the key parts of the penis being in close contact with the ridge-like protrusion. Since the ridge-like protrusion 405 applies the pressure in a concentrated manner, the pressure P1 generated therefrom is obviously higher than the average pressure P0 applied by the thin-walled structure 1 to other parts of the penis, this design effectively controls an ejaculation process, extends the duration of sexual intercourse, and improves physiological experience of the user.

The ridge-like protrusion 405 can be designed in various shapes, such as linear, wavy, or toothed, to provide different forms of compression sensation. The ridge-like protrusion 405 is usually made from silicone or soft plastic with good elasticity to ensure that the massage device can maintain wearing comfort and safety while providing sufficient compression force. Height and hardness of the ridge-like protrusion 405 is carefully designed to adapt to physiological characteristics of different users, thereby providing effective compression while avoiding excessive stimulation or discomfort.

By incorporating the ridge-like protrusion 405, this embodiment can provide more precise local compression, the design of the ridge-like protrusion 405 allows for concentrated force to the key parts of the penis, thereby significantly improving ejaculating control effects and delaying the ejaculating time, which is particularly beneficial for the users with premature ejaculation problem and is capable of helping them better control rhythm of sexual intercourse.

Since the ridge-like protrusion 405 can provide increased compression to the specific area, this embodiment cannot only achieve the ejaculating control function, but also improve the physiological experience of the user by stimulating the specific parts of the penis, and the user can accordingly feel a stronger sense of stimulation, thereby improving the overall sexual pleasure.

Although the ridge-like protrusion 405 strengthens the local compression intensity, but design and material of the ridge-like protrusion ensure comfort of wearing. Elasticity and softness of the ridge-like protrusion 405 prevent discomfort or damage to the penis while providing compression, which not only ensures the ejaculating control effects, but also guarantees the comfort during wearing.

The design of this embodiment is suitable for various scenarios and can play an effective role in both daily use and physiological regulations in special situations. The user can choose different shapes and sizes of the ridge-like protrusion 405 to achieve personalized physiotherapy effects.

In this embodiment, by arranging the ridge-like protrusion 405 in the ejaculating compression and control area 4, this embodiment further improves the ejaculating control effects and user experience of the bidirectional stimulation massage device. The local compression provided by the ridge-like protrusion 405 allows for more precise ejaculating control and improved physiological pleasure, making the massage device have a wide application value in the reproductive health and sexual function improvement.

As shown in FIGS. 1, 4 and 43, a fifth embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, a position of the first stimulation device 3 on the circumferential wall surface of the thin-walled structure 1 is defined as a first region 1701;

• • a position of the ridge-like protrusion 405 on the circumferential wall surface of the thin-walled structure 1 are defined as a second region 1702; and
  • the first region 1701 and the second region 1702 are arranged opposite to each other at an interval of 180°.

In this embodiment, the first region 1701 and the second region 1702 are arranged opposite to each other in a circumferential direction, and the layout design ensures that the massage device can provide multiple stimulations from different angles simultaneously during use.

Generally, when the bidirectional stimulation massage device is worn on a male penis, the first region 1701 is specifically a local portion of the circumferential wall of the thin-walled structure 1 facing upward, and the local portion is usually a region located in a middle of the circumferential wall of the thin-walled structure 1. The second region 1702 is specifically another local portion of the circumferential wall of the thin-walled structure 1 facing downward, such that the first region 1701 and the second region 1702 are in a relative positional relationship, and the another local portion is usually also a region located in a middle of the circumferential wall of the thin-walled structure 1.

When the massage device is in a shallow insertion state, the first stimulation device 3 can precisely stimulate a female C point (clitoris) and the surface of the male penis. At the same time, the ridge-like protrusion 405 located in the Second region 7102 on the circumferential wall surface of the thin-walled structure 1 can apply pressure to local vas deferens of the male penis, and this design achieves synchronized stimulation and physiological regulation for both partners by stimulating the C point of the female and the vas deferens of the male simultaneously in the shallow insertion state.

When the massage device is in a deep insertion state, the first stimulation device 3 can be inserted into an area of the inner wall of the vagina, providing deeper vibration or mechanical stimulation, and at the same time, the ridge-like protrusion 405 continues to apply pressure to the vas deferens of the male, such that the first stimulation device 3 can effectively stimulate the inner wall of the vagina of the female, while the ridge-like protrusion 405 can enhance the ejaculating control effects of the male penis.

This embodiment can realize synchronized stimulation of both partners at various points from various angles by arranging the first stimulation device 3 and the ridge-like protrusion 405 opposite to each other at an interval of 180°. The massage device is capable of providing targeted physiological stimulation and improving overall experience of the user both in the shallow insertion state and in the deep insertion state. This design, especially during sexual intercourse, can prolong the duration of sexual intercourse, improve sexual pleasure, and improve the harmony of interactions between partners.

As shown in FIGS. 44-46, a sixth embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, both the inner wall 101 and the outer wall 102 are provided with a flexible surface layer 6, including:

• • a vibration transmission element 5;
  • where the inner wall 101 and the outer wall 102 enclose to form an accommodating cavity;
  • the vibration transmission element 5 is arranged inside the accommodating cavity;
  • a hardness D1 of the vibration transmission element 5 is greater than a hardness D2 of the flexible surface layer 6; and
  • the first stimulation device 3 is arranged inside the vibration transmission element 5, which is configured to transmit mechanical vibrations from the first stimulation device 3 to a covered area (referring to the circumferential wall surface of the thin-walled structure 1 being in contact with a human body part).

In this embodiment, a primary function of the vibration transmission element 5 is to efficiently transmit the mechanical vibrations generated by the first stimulation device 3 to the inner wall 101 and the outer wall 102 of the thin-walled structure 1. Since the hardness D1 of the vibration transmission element 5 is greater than the hardness D2 of the flexible surface layer 6, the vibration transmission element can better transmit vibration energy, and reduce energy loss during transmission, that is, although a vibration source may be located only in one local area, the vibrations can be quickly and evenly dispersed to both inner and outer surfaces of the entire thin-walled structure 1 through a medium effect of the vibration transmission element 5.

The arrangement of the vibration transmission element 5 enables the vibration energy to be extended from the local area of the first stimulation device 3 to a larger area, even covering the inner wall 101 and the outer wall 102 of the entire thin-walled structure 1. This extended function makes the user feel vibration stimulation over the larger area when the device is worn, rather than just in the vicinity of the vibration source, the stimulation from all directions can provide more excellent massage experience, contributing to the improvement of overall physiotherapy effects.

The vibration transmission element 5 further plays a role in evenly distributing the vibrations. During the transmission process of vibrations, the vibration transmission element 5 can avoid excessive concentration of vibrations in the local area, and evenly disperse the vibrations to the covered area, the even distribution effects are very important as it can ensure that both the inner wall 101 and the outer wall 102 of the entire thin-walled structure 1 receive synchronized vibration stimulation, thereby avoiding discomfort or suboptimal physiotherapy effects caused by excessive or weak local vibrations.

The vibration transmission element 5, due to high hardness and conductivity of its material, can maintain stability of vibrations, and ensure that the vibration intensity will not be significantly attenuated during the transmission process. that is, the vibration transmission element 5 can stably transmit the vibration energy to a target area, regardless of the power of the vibration source, thereby providing continuous and effective stimulation.

The vibration transmission element 5 further has a structural support function, and can provide necessary support to the flexible surface layer 6, thereby preventing the flexible material from being overly deformed under stress, which could affect the vibration transmission effects. In addition, the vibration transmission element 5 can protect the first stimulation device 3 therein from external pressure or impact, thereby extending the service life of the massage device.

By adjusting shape, thickness, or material of the vibration transmission element 5, various types of vibration effects can be achieved. For example, a thinner transmission element can provide more sensitive high-frequency vibrations, while a thicker or harder transmission element can produce deeper low-frequency vibrations, and diverse vibration effects can meet personalized needs of different users, making the massage device adaptable to various physiotherapy and massage scenarios.

Therefore, the vibration transmission element 5 plays a crucial role in this embodiment, it is not only a core medium for transmitting the mechanical vibrations, but also plays a key role in extending a vibration range, even distribution of vibrations, maintenance of stability of the massage device, and structural support, and the like. Through the optimized design of the vibration transmission element 5, the bidirectional stimulation massage device can provide the user with more comprehensive, comfortable, and effective massage experience.

Moreover, the material selection of the vibration transmission element 5 is essential for efficient transmission of vibrations and stable structural support. In this embodiment, the material of the vibration transmission element 5 can be optimized and selected according to different needs, and some common material suitable for the vibration transmission element 5 are described as follows:

• • metal alloys such as aluminum alloy, stainless steel, and titanium alloy.

Characteristics: metal alloys have high hardness and excellent performance of vibration transmission, and they can quickly transmit vibration energy while maintaining stability and intensity of the vibrations. Metal alloys also provide good durability and fatigue resistance, making them suitable for suitable for scenarios that require high intensity and long-term use.

Applicable scenarios: the transmission element made from the metal alloys is suitable for applications that require strong vibrations and deep massage effects, especially for physiotherapy devices, and stable and robust vibration transmission can be accordingly provided.

Rigid plastics such as polyamide (nylon), polycarbonate (PC), and polyoxymethylene (POM).

Characteristics: rigid plastic materials are lightweight, with good mechanical strength and wear resistance, therefore, they can effectively transmit vibrations while providing a certain degree of flexibility, making them suitable for being designed into various complex shapes to meet different device requirements. Rigid plastics also feature good processability and low cost, making them ideal for mass production.

Applicable scenarios: the rigid plastics are suitable for vibration devices that require lightweight design, especially for portable massage devices, and efficient vibration transmission and comfortable user experience can be accordingly provided.

Carbon fiber composite material, glass fiber composite material, carbon nanotube reinforced composite material, and the like.

Characteristics: the composite materials have high strength, light weight, and excellent vibration transmission performance, and they can effectively transmit and evenly distribute vibration energy, while having high design flexibility. The composite materials usually have good fatigue resistance, and are suitable for the design of high-performance devices.

Applicable scenarios: composite materials are suitable for high-end massage devices or application scenarios that require superior performance, and they can provide excellent vibration transmission effects while reducing device weight, thereby improving portability and comfort of the devices.

Silicone-reinforced materials such as silicone and metal or fiber composite materials.

Characteristics: silicone is usually soft and elastic, but when being compounded with metal or fiber materials, silicone-reinforced materials can be formed, hardness and vibration transmission performance of the silicone can be significantly enhanced. Silicone-reinforced materials retain the comfort and safety of silicone while improving the vibration transmission capability thereof.

Applicable scenarios: silicone-reinforced materials are suitable for application scenarios that require a balance between comfort and effective vibration transmission, especially for massage devices that need to be worn for a long period of time, and more comfortable user experience can be accordingly provided.

Hardness and density of materials determine the efficiency of vibration transmission. The metal alloys and composite materials usually have higher transmission efficiency, while rigid plastics have relatively lower efficiency, which, however, can be compensated by optimizing the design.

For a portable or long-wearing device, weight of the material is crucial. The composite material and rigid plastics are often selected for the device due to their lightweight advantages. The silicone-reinforced materials balance comfort and effective vibration transmission.

The processing difficulty and cost of different material vary greatly. The rigid plastics have good processability, and are suitable for mass production, while the composite materials and metal alloys require more complex processing technology and are more costly.

Selection of the material for the vibration transmission element 5 largely determines the performance, comfort, and service life of the massage device. In this embodiment, the metal alloys, rigid plastics, composites, or silicone-reinforced materials can be selected according to different application requirements. The materials have their respective unique characteristics, and efficient vibration transmission, stability, and user comfort of the vibration transmission element 5 can be achieved by selecting reasonable material and optimizing the design.

As shown in FIGS. 1, and 44-46, a seventh embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, the vibration transmission element 5 includes:

• • a first transmission edge 501;
  • where the first transmission edge 501 is arranged at a front end 1703 of the thin-walled structure 1 in the axial direction.

In this embodiment, the vibration transmission element 5 is designed to have the first transmission edge 501, which is arranged at the front end 1703 in the axial direction of the thin-walled structure 1, this design allows for the concentration and effective transmission of vibration energy to the front end 1703, providing stronger stimulation to a target part at the front end 1703.

Specifically, the design of the first transmission edge 501 is intended to enhance the vibration effects at the front end 1703 of the thin-walled structure 1. The front end 1703 of the thin-walled structure 1 is usually in contact with sensitive parts (such as the C point or vaginal entrance of the female) during massage. By concentrating the vibration energy on the first transmission edge 501, the massage device can provide more precise and intense stimulation effects in the shallow insertion state, thereby improving the physiological experience of the user.

In the deep insertion state, the first transmission edge 501 can further enhance stimulation of the inner wall of the vagina or the male penis by linkage with other components (such as internal mechanical structures). Through the multi-functional approach, the arrangement of the vibration transmission element 5 allows for balanced and effective physiotherapy effects in the application scenarios at different depths.

By arranging the first transmission edge 501 at the front end 1703, this embodiment realizes concentrated transmission of vibration energy, this design can effectively enhance the vibration intensify at the front end 1703 and provide the user with stronger and more precise stimulation, and is especially suitable for massage of the sensitive parts.

The vibration concentrated at the front end 1703 can directly act on the sensitive parts, such as the C point of the female, in the shallow insertion state, significantly improving the physiological pleasure of the user. In addition, in the deep insertion state, the design of the first conduction edge 501 can further enhance continuous stimulation of the inner wall of the vagina or the male penis, producing deeper massage effects.

Since the first transmission edge 501 can effectively concentrate and transmit the vibration energy, the massage device exhibits excellent performance at various depths and in different application scenarios. The massage device can flexibly adapt to different needs of the user, both for local strong stimulation in the shallow insertion state and for wide massage in the deep insertion state.

The design of the first transmission edge 501 optimizes the energy utilization efficiency of the vibration transmission element 5. By concentrating and transmitting the vibrations to the front end 1703, the energy waste is reduced, such that the massage device can produce stronger stimulation effects at relatively low energy consumption, and the overall efficiency of the massage device is improved.

In this embodiment, by arranging the first transmission edge 501 on the vibration transmission element 5, the bidirectional stimulation massage device can more accurately concentrate the vibration energy on the front end 1703 of the thin-walled structure 1. This design not only significantly enhances the intensity and effects of stimulation at the front end 1703, but also improves the adaptability and user experience of the massage device in various application scenarios.

As shown in FIGS. 44-46, an eighth embodiment of the disclosure provides a bidirectional stimulation massage device, and on the basis of the previous embodiment, the vibration transmission element 5 includes:

• • a first transmission area 1704;
  • a second transmission area 1705;
  • where the first transmission area 1704 and the second transmission area 1705 extend from a center of the first region 1701 respectively along the circumferential wall surface of the thin-walled structure 1 towards the second region 1702; and
  • a radian covered by a surface area formed by the extension of the first transmission area 1704 and the second transmission area 1705 on the circumferential wall surface of the thin-walled structure 1 is less than π/2.

In this embodiment, the vibration transmission element 5 is divided into two main transmission areas, that is, S11 and S12, the first transmission area 1704 and the second transmission area 1705 are centered on the center of the first region 1701 and extend towards the second region 1702 along a circumference of the thin-walled structure 1. This design enables the vibration to extend from a center point of the first region 1701 to both sides, forming a wider vibration coverage.

Specifically, a coverage area formed by the extension of the first transmission area 1704 and the second transmission area 1705 on the circumferential wall surface of the thin-walled structure 1 has a radian not less than π/2. This wide-angle coverage design ensures that the vibration transmission element 5 can cover a larger area of both the inner wall 101 and the outer wall 102 of the thin-walled structure 1, thereby providing the user with more uniform vibration stimulation from all directions. This design is particularly suitable for massage and physiotherapy scenarios that require extensive vibration effects. Since the first transmission area 1704 and the second transmission area 1705 are respectively located on two sides of the circumference of the thin-walled structure 1 and are symmetrically distributed, they can maintain good balance during the vibration transmission process. The symmetry ensures that the vibration energy can be transmitted evenly in the areas on both sides, and the overall massage effects of the massage device are accordingly improved.

By extending the first transmission area 1704 and the second transmission area 1705, the vibration transmission element 5 is capable of simultaneously producing vibration at a plurality of points on the inner wall 101 and the outer wall 102, The synchronized stimulation at the plurality of points can provide three-dimensional massage experience, and is suitable for reproductive health physiotherapy that requires stimulation of various parts at the same time.

The design of radian coverage of the first transmission area 1704 and the second transmission area 1705 ensures that vibration can spread over a larger area of the thin-walled structure 1, especially when the radian is not less than π/2, the vibration energy can better act on a larger massage area. The user can feel even stimulation from various directions, both on the inner wall 101 and the outer wall 102 of the thin-walled structure 1.

Through the symmetrical design of the first transmission area 1704 and the second transmission area 1705, this embodiment can ensure the balance of vibration transmission. The synchronized transmission of vibration on both sides keeps the entire thin-walled structure 1 stable during operation, thereby avoiding the problem of reduced comfort or suboptimal massage effects due to uneven vibration.

By virtue of a wider and more uniform vibration coverage area, this embodiment can provide the user with deeper and more comprehensive massage experience, especially for the users who require simultaneous vibration stimulation at different points in various directions, this design can significantly improve the comfort and effects.

In another specific embodiment, the radian covered by the surface area formed by the extension of the first transmission area 1704 and the second transmission area 1705 on the circumferential wall surface of the thin-walled structure ranges from 1.7 to π, this design further expands the vibration coverage area and enhances the transmission effects, providing the user with deeper and more comprehensive massage experience.

A range of radian covered by the surface area formed by the extension of the first transmission area 1704 and the second transmission area 1705 on the circumferential wall surface of the thin-walled structure is designed to be 1.7 to π. Compared to the previous design with a range of radian being not less than π/2, the expanded range of radian can cover a large area of the thin-walled structure 1, such that an effective area for vibration can be increased, and more extensive physiological stimulation can be realized.

When a coverage radian of the first transmission area 1704 and the second transmission 1705 in the circumferential wall direction of the thin-walled structure 1 is expanded to 1.7 to π, the vibration transmission element 5 can transmit vibration energy across a larger area of the inner wall 101 and the outer wall 102 of the thin-walled structure 1, and more comprehensive stimulation, both for the penis on the inner wall 101 and for the vagina on the outer wall 102, can be realized. This design provides the user with stronger, more uniform, and continuous stimulation when the massage device is used.

A greater radian formed by the extension of the first transmission area 1704 and the second transmission area 1705 ensures that vibration is not just concentrated in a small area, but can form a synergistic effect across multiple areas, the synergistic effect is particularly suitable for reproductive health physiotherapy that requires simultaneous stimulation of multiple areas, which can enhance the massage effects while improving the overall user experience.

The expanded range of radian allows for more precise adjustment to the design of the first transmission area 1704 and the second transmission area 1705. For example, by setting different vibration intensities or frequencies in the first transmission area 1704 and the second transmission area 1705, the user can enjoy personalized massage. This design provides the user with more options, making the massage device adaptable to a wider range of application scenarios and personal needs.

The design of expanded range of radian enables the massage device adaptable to various application scenarios, whether for daily reproductive health physiotherapy or for sexual function regulation in special cases, it can provide physiotherapy effects, The versatility of the massage device makes it have greater market potential and competitiveness.
