The present application relates to the field of massage apparatuses, in particular to a massager with a non-contact driving apparatus.
With the development of living, people's demands or design requirements for massage apparatuses are higher and higher, herein the setting of touch and working frequency is included.
However, the existing massage apparatuses, such as United States patent U.S. Pat. No. 11,389,374B1, use a combination of a driving assembly and an expansion assembly, to achieve relative movement between a soft colloid and a soft piece, thereby the massage function is achieved.
It mainly achieves displacement difference by a cam structure, thereby the relative movement is achieved. Therefore, mechanical vibration is relatively large, and its movement stroke is intermittent, the movement is not linear enough, and some also have some noise and rigid contact problems.
A main purpose of the present application is to provide a massager with a non-contact driving apparatus, and aims to improve an existing driving structure. A soft piece may achieve flexible movement, and its movement stroke is linear, thus the massage function is softer. At the same time, it may achieve vibration or swing in a non-contact driving mode, and it is a scheme to replace an existing vibrating motor or cam apparatus.
In order to achieve the above purpose, the present application provides a massager with a non-contact driving apparatus, including:
In a practical design, a technical scheme of the present application improves the structure of the driving apparatus, thereby linear variation of fluid is achieved, and movement intermittency caused by an existing cam mechanism is avoided, so that the movement of the soft piece is softer. At the same time, a non-contact driving mode is adopted to achieve non-contact driving of the soft piece, and directional vibration or directional swing may be achieved.
Firstly, the driving seat is mounted in the position of the rotating shaft, then the screw guide seat is fixed on the rotating motor, the expansion seat is mounted on the screw guide seat, and finally the steel ball is mounted on the expansion seat, the steel ball is allowed to pass through the guide groove and stuck in the spiral groove; and when the rotating motor rotates, the steel ball rotates with the spiral groove and forces the expansion seat to move vertically back and forth along a height direction of the guide groove, namely the expansion seat achieves up and down movement of the expansion seat by the loop-closed spiral groove. At the same time, by the reciprocating movement of the expansion seat in the closed cavity, the pressure change of the fluid through hole is achieved, and the air pressure change is more linear, and the stability is better.
For example, when the rotating motor rotates clockwise, the expansion seat achieves relative air intake; when the rotating motor rotates counterclockwise, the expansion seat achieves relative air supply; and thus, the positive and negative air pressure switching of the closed cavity is achieved, and the air flow is uniform and stable, the air pressure is stronger, thereby it is guaranteed that an air pump achieves the corresponding function.
Technical schemes in embodiments of the present application are clearly and completely described below in combination with the drawings. Apparently, the embodiments described are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without paying creative labor shall fall within the scope of protection of the present application.
It should be noted that if a directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, and axial) is involved in the embodiments of the present application, the directional indication is only used to explain a relative position relationship, a motion situation and the like between various components in a specific posture (as shown in the drawings). If the specific posture is changed, the directional indication is also changed accordingly with it.
In addition, if there is a description of “first” or “second” or the like in the embodiments of the present application, the description of “first” or “second” or the like is only for the purpose of description and may not be understood as indicating or implying its relative importance or implying the number of technical features indicated. Therefore, the features limited to the “first” and “second” may explicitly or implicitly include at least one of these features. In addition, the technical schemes between various embodiments may be combined with each other, but must be based on what those of ordinary skill in the art may achieve. When a combination of the technical schemes is contradictory or impossible to achieve, it should be considered that this combination of the technical schemes does not exist and is not within the scope of protection claimed by the present application.
As shown in
In a practical design, by improving the structure of the driving apparatus 100, linear variation of fluid is achieved, and movement intermittency caused by an existing cam mechanism is avoided, so that the movement of the soft piece is softer. At the same time, a non-contact driving mode is adopted to achieve non-contact driving of the soft piece.
Firstly, the driving seat 2 is mounted in the position of the rotating shaft 11, then the screw guide seat 3 is fixed on the rotating motor 1, the expansion seat 4 is mounted on the screw guide seat 3, and finally the steel ball 42 is mounted on the expansion seat 4, the steel ball 42 is allowed to pass through the guide groove 31 and stuck in the spiral groove 21; and when the rotating motor 1 rotates, the steel ball 42 rotates with the spiral groove 21 and forces the expansion seat 4 to move vertically back and forth along a height direction of the guide groove 31, namely the expansion seat 4 achieves up and down movement of the expansion seat 4 by the loop-closed spiral groove 21. At the same time, by the reciprocating movement of the expansion seat 4 in the closed cavity 200, the pressure change of the fluid through hole 41 is achieved, and the air pressure change is more linear, and the stability is better.
For example, when the rotating motor 1 rotates clockwise, the expansion seat 4 achieves relative air intake; when the rotating motor 1 rotates counterclockwise, the expansion seat 4 achieves relative air supply; and thus, the positive and negative air pressure switching of the closed cavity 200 is achieved, and the air flow is uniform and stable, the air pressure is stronger, thereby it is guaranteed that an air pump achieves the corresponding function.
Specifically, a driving end of the rotating motor is connected with a gearbox 12, as to deliver a more stable torque, thereby linear sliding of the expansion seat 4 is guaranteed, and linear switching of positive and negative air pressures is achieved.
Specifically, an upper wall of the rotating motor is provided with positioning columns 51 arranged at intervals, and the screw guide seat 3 is provided with a positioning hole 52 matched with the positioning seat 8a, thereby the mounting and fixing of the screw guide seat 3 are achieved.
Specifically, the spiral groove 21 is composed of two arc-shaped grooves 211 arranged symmetrically and obliquely; and the depth of the spiral groove 21 is greater than a half of the diameter of the steel ball 42, thereby the vertical movement of the expansion seat 4 driven by the steel ball 42 is achieved.
Specifically, the expansion seat 4 is provided with a clamping hole 43, two sides of the clamping hole 43 are provided with a screw hole 44, the steel ball 42 is arranged in a position in which there is the screw hole 44, the clamping hole 43 is provided with an outer cover 6 that wraps the steel ball 42 inside it, and the outer cover 6 is provided with a via hole 61 matched with the screw hole 44, thereby the convenient mounting of the steel ball is achieved.
In a first embodiment, the positioning seat 8a includes a hard bottom seat 81 mounted on the hard inner housing 71 and a soft top seat 82 mounted on the hard bottom seat 81, the hard bottom seat 81 and the soft top seat 82 are enclosed as a sliding groove 80.
The soft piece is a flowing guide ball 8, the fluid inlet 8c is arranged in the hard bottom seat 81, the flowing guide ball 8 may move relatively along the sliding groove 80 and switch between a closed position and an opened position of the fluid inlet 8c. The soft top seat 82 is matched with the flowing guide ball 8 of the soft piece, herein the soft top seat 82 is used to imitate a mouth of a human body, and the flowing guide ball 8 is used to imitate a tongue of the human body. When the air pressure is changed and drives the flowing guide ball 8 to move, a guide structure may also be arranged between the flowing guide ball 8 and the hard bottom seat 81, as to achieve reciprocating movement in a predetermined direction (while blowing and inhaling are satisfied).
Specifically, the flowing guide ball 8 is elliptical in shape with a diameter expanded gradually from top to bottom, and the fluid inlet 8c and the fluid through hole 41 are connected by a guide tube 8d, which not only satisfies the closure of the fluid inlet 8c but also imitate the tongue of the human body.
In a second embodiment, the soft piece 8b is an elastic film 9, the positioning seat 8a is a hard arc-shaped seat 91 of which an upper end is provided with an opening, the elastic film 9 wraps the opening and is enclosed as a vibrating cavity 90, the fluid inlet 8c is arranged in the hard arc-shaped seat 91, the fluid inlet 8c and the fluid through hole 41 are connected by the guide tube 8d, and when the positive and negative pressure fluid is conveyed to the vibrating cavity 90, it may force the elastic film 9 to vibrate and make a predetermined stroke.
Herein the elastic film 9 may have a certain degree of elasticity. When the fluid is negative, the elastic film 9 is deformed inwards, and when the fluid is positive, the elastic film 9 may be deformed upwards or be reset by the elastic deformation of the elastic film 9, thereby reciprocating vibration of the elastic film 9 is achieved; and certainly, the movement direction of the elastic film 9 may also be set oppositely, and the same technical effect may also be achieved.
Specifically, a middle portion of the elastic film 9 is protruded upwards and provided with a tongue portion 92, thereby the tongue of the human body is imitated; and the elastic film 9 is circular in shape, and a wall surface of the elastic film 9 has a concave-convex arc, thereby the stroke direction limit of the elastic film 9 is achieved.
Specifically, the soft outer housing 72 extends upwards and is arranged on the periphery of the hard arc-shaped seat 91 to form an enclosure portion 93, herein the enclosure portion 93 is used to imitate the mouth of the human body.
Herein this design converts the axial rotation of the rotating motor 1 into the reciprocating linear movement of the expansion seat 4, thereby the changes of the air pressure are achieved (it may be understood as blowing or inhaling).
The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structural changes made by using the contents of the description and drawings of the present application, under the inventive concept of the present application or directly/indirectly applied in other related technical fields, are all included in the scope of patent protection of the present application.
