CROSS REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims foreign priority to Chinese Patent Application No. 202410457947.9, filed on Apr. 16, 2024, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure belongs to the field of massagers, relates to technology for improving stimulation effects of the massagers, and particularly relates to a volute shell-type massage structure and a volute shell-type massager.

BACKGROUND

Massage aims to achieve health, pleasure and stimulation by imposing direct action on a massaged subject, the commercial market of massagers accordingly witnesses rapid growth. Among a variety of massage products, a massage product that constructs a massage body thereof in a volute or similar structures becomes more prominent, which produces stimulating effects on a massaged part by rolling back and forth of the massage body.

In the prior art, there are many improvements to volute shell-type massagers. For example, FIGS. 1-3 illustrate a design, in which a volute shell massage body 10 is mounted at an end of a carrier 9. As the carrier 9 enters a human body, an arm body 1001 of the volute shell massage body 10 will stretch out, allowing a head portion 1002 thereof to exert some pressure on an outer surface of the human body (such as a clitoris), thereby producing dual internal and external massage stimulation effects. However, the structure above has the following problems:

since the arm body 1001 needs to, together with the carrier 9, enter the human body, a length of the arm body 1001 needs to be extended, which makes rewinding force received by the head portion 1002 difficult to be distributed evenly, thereby affecting the balance of pressure exerted on the outer surface of the human body.

Extension of the length of the arm body 1001 leads to an increase in a number of volute turns of the head portion 1002, making the head portion 1002 heavier. When the carrier 9 deviates at a certain angle, the head portion 1002 will deviate from one side of an axis of the carrier 9, resulting in gradual displacement of the massage body during the stretching process, and making it impossible to massage the intended part.

DETAILED DESCRIPTIONS OF THE EMBODIMENTS

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

With reference to FIGS. 4-22, specific embodiments provided by the present disclosure are as follows:

• • as shown in FIGS. 4-7, a first embodiment of the present disclosure provides a volute shell-type massage structure, including:
  • a wand-type massage body 1 having a front massage end K₁ and a rear gripping end K₂;
  • a volute shell massage body 2 having a volute shell nose 201 and a volute shell body 202;
  • where the volute shell nose 201 is an arc-shaped structure surrounding the volute shell body 202;
  • the volute shell nose 201 is connected to the volute shell body 202 to form a wrapping angle sector S, and a wrapping angle of the wrapping angle sector S is α and composed of an adjacent wrapping angle sector S₁ and a wrapping angle sector S₂;
  • where a wrapping angle of the wrapping angle sector S₁ is α₁, a wrapping angle of the wrapping angle sector S₂ is α₂, and α=α₁+α₂;
  • the volute shell nose 201 in the wrapping angle sector S₁ is continuously connected with the volute shell body 202, and the volute shell nose 201 in the wrapping angle sector S₂ is separated from the volute shell body 202;
  • the volute shell nose 201 has a free end P₁, and the free end P₁ is connected to a K₃ position of the wand-type massage body 1;
  • a length of the wand-type massage body 1 is L, in a length direction of the wand-type massage body 1, a length of the K₃ position to the front massage end K₁ is L₃₁, and a length of the K₃ position to the rear gripping end K₂ is L₃₂, where L₃₂<L₃₁, and L=L₃₁+L₃₂;
  • the volute shell nose 201 is connected to the wand-type massage body 1 to form a connecting angle b₁, the connecting angle b₁ is an angle from a direction M₁ to a direction M₂, and the connecting angle is b₁<90°; and
  • the direction M₁ is a direction from an axis of the volute shell nose 201 at the free end P₁ pointing to a side of the volute shell nose 201, and the direction M₂ is a direction from an axis of the wand-type massage body 1 at the free end P₁ pointing to the rear gripping end K₂.

In this embodiment, the wand-type massage body 1 has a stimulation surface 101, the stimulation surface 101 is a complete circumferential outer wall surface of the wand-type massage body 1, and is configured to contact an inner cavity 3 of a hole-shaped part to be massaged when a carrier enters a human body and produce massage stimulation effects.

An end of the wand-type massage body 1 that is first inserted into the human body is the front massage end K₁, and one end away from the front massage end K₁ is the rear gripping end K₂ gripped by a user.

In practical user, taking the hole-shaped part to be massaged of the human body as an example, the user grips the rear gripping end K₂ to allow the wand-type massage body 1 to be inserted into the inner cavity 3 of the hole-shaped part to be massaged through the front massage end K₁, such that the stimulation surface 101 can produce massage stimulation to the inner cavity 3 of the hole-shaped part to be massaged by means of thrusting the wand-type massage body 1.

It is found on the basis of the above that when the volute shell massage body 2 is disposed at the front massage end K₁ or close to the front massage end K₁, a length of the volute shell nose 201 needs to be increased to ensure that the volute shell nose enters the human body along with the wand-type massage body 1, which will lead to the problems that massage pressure of the volute shell body 202 on an outer surface of the human body is uneven, and the volute shell body 202 is prone to deflection.

On this basis, in this embodiment, the volute shell massage body 2 is provided at the K₃ position, and a length L₃₂ from the position K₃ to the rear gripping end K₂ is less than a length L₃₁ from the position K₃ to the front massage end K₁, that is, the free end P₁ of the volute shell nose 201 is mounted at the K₃ position, a certain distance exists from the volute shell massage body 2 to the front massage end K₁, and the volute shell massage body 2 is not in contact with an outer surface 4 of the hole-shaped part to be massaged at least when the front massage end K₁ is inserted into the inner cavity 3 of the hole-shaped part to be massaged. Therefore, it is unnecessary to extend the length of the volute shell nose 201, thereby avoiding the problem of deflection of the volute shell body 202.

It is further found that the massage pressure exerted by the volute shell body 202 on the outer surface 4 of the hole-shaped part to be massaged needs to fall within a reasonable range. Under the condition that the massage pressure is too high, stimulation pain will be caused; and under the condition that the massage pressure is too low, massage sensation will be weakened. Further, the wand-type massage body 1 gradually enters deep into the inner cavity 3 of the hole-shaped part to be massaged, and the outer surface 4 of the hole-shaped part to be massaged is in contact with the volute shell massage body 2 until the entire period that the volute shell massage body 2 produces the massage pressure, this embodiment expects that the massage pressure is balanced, and the balanced pressure can be maintained adaptively according to a depth distance of the wand-type massage body 1.

Therefore, the volute shell nose 201 and the volute shell body 202 are further optimized:

• • the volute shell nose 201 and the volute shell body 202 form a continuous connection in the wrapping angle sector S₁, where “continuous connection” is defined as: the volute shell nose 201 forms a connecting end P₂ attached to a circumferential wall surface of the volute shell body 202 in shape, and the volute shell nose and the volute shell body are connected to each other on part of the circumferential wall surface of the volute shell body 202.

The above form has the advantages that: connection strength between the volute shell nose 201 and the volute shell body 202 is enhanced, and when the volute shell body 202 is in contact with the outer surface 4 of the hole-shaped part to be massaged, the connecting end P₂ can conduct acting force (the force exerted by the outer surface 4 of the hole-shaped part to be massaged on the volute shell body 202) to the volute shell nose 201, and the volute shell nose 201 is driven to perform action.

The volute shell nose 201 and the volute shell body 202 are separated from each other in the wrapping angle sector S₂, where “separated” is defined as: the volute shell nose 201 and the volute shell body 202 are in a separated state, that is, a gap 5 exists between the volute shell nose and the volute shell body, which is not a process of dynamically separating due to some acting force.

The above form has the advantages that: due to existence of the gap 5, when the volute shell body 202 is in contact with the outer surface 4 of the hole-shaped part to be massaged, the gap 5 can be compressed, such that the volute shell body 202 first performs displacement actions in the length direction of the wand-type massage body 1, thereby avoiding the problem of jamming of the volute shell body 202.

The wrapping angle α₁ of the wrapping angle sector S₁ and the wrapping angle α₂ of the wrapping angle sector S₂ form the wrapping angle α of the wrapping angle sector S.

The above form has the advantages that: the volute shell body 202 and the volute shell nose 201 form a volute structure, and when the volute shell body 202 is subjected to the acting force of the outer surface 4 of the hole-shaped part to be massaged, the volute shell nose 201 is capable of exerting retraction force on the volute shell body 202 that always faces the outer surface 4 of the hole-shaped part to be massaged, such that the volute shell body 202 keeps a massage posture attached to the outer surface 4 of the hole-shaped part to be massaged, and relatively strong and uninterrupted massage stimulation effects are accordingly achieved.

On the basis of the above, it is further found that:

First, since the inner cavity 3 of the hole-shaped part to be massaged of the user is different in depth, but what needs to be ensure is that: after the user inserts the wand-type massage body 1 to a deeper or shallower depth, the volute shell massage body 2 has a certain action stroke in the length direction of the wand-type massage body 1, thereby facilitating that the volute shell body 202 is always attached to a desired part to be massaged and to produce massage stimulation effects, preventing the volute shell body 202 from forming a barrier to the outer surface 4 of the hole-shaped part to be massaged, and accordingly avoiding the problem of insertion obstruction. Further, a difference between a maximum pressure and a minimum pressure exerted by the volute shell body 202 on the outer surface 4 of the hole-shaped part to be massaged is close to 0, that is, the pressure remains balanced rather than changes significantly.

Second, a degree of stimulation felt by the outer surface 4 of the hole-shaped part to be massaged is related to a massage form. For example, when the volute shell body 202 forms relatively static friction with the outer surface of the hole-shaped part to be massaged, the degree of stimulation will be reduced. When the volute shell body 202 forms relatively sliding or rolling friction with the outer surface of the hole-shaped part to be massaged, the degree of stimulation will be significantly improved.

Based on the above two points, the volute shell nose 201 is connected to the wand-type massage body 1 to form the connecting angle b₁ (the connecting angle b₁ is an angle from a direction M₁ to a direction M₂, and the connecting angle b₁ is <) 90°.

The above form has the advantages that: when interactions between the outer surface 4 of the hole-shaped part to be massaged and the volute shell body 202 is decomposed, it can be seen that, in a first stage, that is, an initial contact stage between the outer surface 4 of the hole-shaped part to be massaged and the volute shell body 202, since the volute shell body 202 and due to the existence of the gap 5, the volute shell body 202 will compress the gap 5 and move towards the rear gripping end K₂, in which case, the volute shell body 202 and the outer surface 4 of the hole-shaped part to be massaged form relatively static friction. In a second stage, that is, as an insertion depth increases and the gap 5 is compressed to an extreme position (that is, a value of the gap 5 is 0), the volute shell body 202 performs flipping actions by taking the connecting end P₂ as a flipping point, in which case, the volute shell body 202 and the outer surface 4 of the hole-shaped part to be massaged produce relatively sliding friction, such that strong massage stimulation effects are achieved. Of course, as the flipping actions is performed, the volute shell nose 201 allows the volute shell body 202 to synchronously in the length direction of the wand-type massage body 1, such that the volute shell body 202 can always keep the massage posture attached to the outer surface 4 of the hole-shaped part to be massaged to perform adaptive massage actions. Further, since the volute shell nose 201 is an arc-shaped structure surrounding the volute shell body 202, when the volute shell body 202 flips over, a direction of the acting force exerted by the volute shell nose 201 on the volute shell body 202 also gradually tends to be opposite to a direction of the acting force exerted by the outer surface 4 of the hole-shaped part to be massaged on the volute shell body 202, such that that the acting force is prevented from being resolved and consumed in other directions, and the acting force (directly represented as the pressure exerted on the outer surface 4 of the hole-shaped part to be massaged) is not weakened, and a balanced effect of the actions force is finally presented.

The above discussion is equivalent to the discussion of decomposing the actions of the volute shell body 202, and as a whole, the actions of the volute shell body 202 is equivalent to swinging actions along the free end P₁. Therefore, the volute shell nose 201 serves as a swinging arm, and the volute shell body 202 is accordingly allowed to perform the swinging actions; and further, since the volute shell nose 201 is an arc-shaped structure surrounding the volute shell body 202, the volute shell nose always exerts the acting force on the volute shell body 202 that faces the outer surface 4 of the hole-shaped part to be massaged, and a direction of the acting force is not perpendicular to the length direction of the wand-type massage body 1, but is parallel to or nearly parallel to the length direction of the wand-type massage body 1, such that a pressure produced by the acting force (the force on the outer surface of the hole-shaped part massage part) is balanced and cannot be decomposed and consumed, and stable massage stimulation effects are achieved.

Further, in the first stage, the volute shell nose 201 is in a retracted state, an arm length thereof is relatively short, therefore, the required resistance will increase, that is, larger acting force F1 needs to be exerted by the hole-shaped part to be massaged on the volute shell body 202. After coming to the second stage, since the gap 5 has been compressed to a minimum, greater resistance is required, that is, the acting force F1, when the volute shell body 202 is required to continue the displacement actions, however, what is expected in this embodiment is that the acting force F1 will be relatively balanced, no matter whether in the first stage or in the second stage. Therefore, the volute shell body 202 will perform the flipping actions during a swinging process, which will make the length of the volute shell nose 201 extended (specifically, the volute shell nose 201 transitions from the retracted state to an unrolled state), that is, the arm length of the swinging arm increases, such that the volute shell body 202 can be pushed to swing despite that the acting force exerted by the outer surface 4 of the hole-shaped part to be massaged on the volute shell body 202 (equivalent to a situation that a resistance arm extends, resistance is accordingly reduced) does not need to be increased, the pressure produced by the volute shell body 202 on the outer surface 4 of the hole-shaped to-be-massaged part does not increase, either (that is, the acting force F1 does not need to be increased), numerical values of changes in the pressure in the first and second phases are relatively small, and balanced and stable massage stimulation effects are finally achieved. Further, with an increase of the length of the volute shell nose 201, elastic force thereof gradually increases, which causes the acting force exerted by the outer surface 4 of the hole-shaped part to be massaged to be increased synchronously (going against the expectation of balanced acting force as devised in this embodiment), therefore, the foregoing process is beneficial to eliminating the disadvantage that the force exerted by the outer surface 4 of the hole-shaped part to be massaged needs to be increased.

Further, due to the existence of the connecting angle b₁, the volute shell nose 201 is allowed to further swing towards the rear gripping end K₂, and an action stroke of the volute shell body 202 is increased by narrowing down a value range of the connecting angle b₁, such that clinging massage stimulation effects are improved at different insertion depths.

As shown in FIG. 8, a second embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the previous embodiment, the wand-type massage body 1 has a symmetrical plane N₁; and

• • the volute shell massage body 2 has a symmetrical plane N₂, where the symmetrical planes N₁ overlaps or substantially overlaps the symmetrical plane N₂.

In this embodiment, since both the volute shell massage body 2 and the wand-type massage body 1 have symmetrical structures, their respective symmetrical planes, that is, the symmetrical plane N₁ and the symmetrical plane N₂ need to coincide with or substantially coincide with each other. That is to say, the volute shell massage body 2 is mounted on an axis of the symmetrical plane of the wand-type massage body 1, such that the volute shell-type massage structure presents a symmetrical structure in terms of appearance, and an aesthetic degree of the structure is ensured. In a structural layer, radial deviation of a mounting position of the volute shell massage body 2 is avoided, such that the volute shell massage body is in contact with a desired part to be massaged.

As shown in FIGS. 5, 13 and 14, a third embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the first embodiment, a proportion interval of L₃₁:L₃₂ ranges from 5:1 to 2:1.

In this embodiment, L₃₁:L₃₂ can be 5:1. Under this parameter, the volute shell massage body 2 is more prone to being close to the rear gripping end K₂, and when a length of L₃₁ is relatively long, the wand-type massage body 1 has a relatively long stimulation surface 101 for inserting into the inner cavity 3 of the hole-shaped part to be massaged, so as to provide stimulation pleasures of thrusting for the user with a deeper depth of the inner cavity 3 of the hole-shaped part to be massaged. Further, as the length of L₃₁ extends, a thrusting period of the wand-type massage body 1 increases, that is, a contact period between the volute shell massage body 2 and the outer surface 4 of the hole-shaped part to be massaged is increased, which provides time for relief from the stimulation sensation felt by the outer surface 4 of the hole-shaped part to be massaged, and massage stimulation is exerted again during a next contact period, such that cyclic and intermittent stimulation effects are produced on the outer surface 4 of the hole-shaped part to be massaged.

In this embodiment, L₃₁:L₃₂ can be 4:1 or 3:1. It should be noted that the proportion interval of L₃₁:L₃₂ reflects changes of the contact period between the volute shell massage body 2 and the hole-shaped part to be massaged to some extent, therefore, the user can select an adaptive range within the proportion interval according to expected needs of the user.

In this embodiment, L₃₁:L₃₂ can be 2:1. Under this parameter, the volute shell massage body 2 is more prone to being close to the front massage end K₁. That is to say, the length of L₃₁ is relatively moderate, and the volute shell massage body 2 can be in contact with the outer surface 4 of the hole-shaped part to be massaged at relatively low frequency and produce stimulation, such that relatively strong and frequent stimulation effects are achieved.

As shown in FIG. 7, a fourth embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the previous embodiment, a value range of the connecting angle b₁ is 50°-85°.

In this embodiment, it is further found that when the value range of the connecting angle b₁ is 40°-10° (or even smaller), the volute shell nose 201 is inclined towards the rear gripping end K₂ and is close to a surface of the wand-type massage main body 1 (that is, the stimulation surface 101), therefore, a swinging amplitude of the volute shell nose 201 will be greatly limited. Specifically, when the volute shell body 202 is subjected to the acting force F1 of the outer surface 4 of the to-be-massaged part, the volute shell body will be stopped by the stimulation surface 101 after swinging to a certain angle, therefore, the volute shell body 202 cannot be driven to perform further actions, causing the volute shell body 202 stopped. Further, in order to solve the above problem, the arm length of the volute shell nose 201 needs to extended, such that a degree of deformation of the volute shell nose 201 (made from elastic material) is improved. However, as the arm length of the volute shell nose 201 extends, a risk of deflection of the volute shell body 202 will increase, therefore, it is unable to provide desired massage stimulation effects. Further, when the value of the connecting angle b₁ falls within 90°-130° (or even greater), the volute shell nose 201 is inclined toward the front massage end K₁ and is close to the surface of the wand-type massage body 1 (that is, the stimulation surface 101). Therefore, when the volute shell body 202 (made from the elastic material) is subjected to the acting force F1 exerted by the outer surface 4 of the hole-shaped part to be massaged, reactions force from the volute shell body 202 is decomposed into the acting force in the length direction of the wand-type massage body 1, and acting force perpendicular to the stimulation surface 101 and pointing to a direction of the stimulation surface 101, which cause the problem that the volute shell body 202 is incapable of flipping over and stopping further actions of the outer surface 4 of the hole-shaped part to be massaged, therefore, the acting force F1 exerted by the outer surface 4 of the hole-shaped part to be massaged needs to be continuously increased, which will cause the stimulation pain.

As shown in FIG. 12, based on this, a value range of the connecting angle b₁ in this embodiment falls within 50°-85°, and further, the value range of the connecting angle b₁ is 30°-70°. Within this parameter range, it can be ensured that a stroke difference X between an initial position O1 and a maximum limit position O2 of the volute shell body 202 (a distance between a center of the volute shell body 202 in the length direction of the wand-type massage body 1) is 2 cm-6 cm (where 1 cm-3 cm is from the compression of the connecting angle b₁), and a value of the corresponding acting force F1 ranges from 1 N-1.5 N (which is 1 N-1.3 N in a first stage, 1.1 N-1.5 N in a second stage, and value changes in the two stages is not very great and is in a relatively balanced state). Further, the value of the acting force F1 is a magnitude of the pressure that can be withstood by the outer surface 4 of the hole-shaped part to be massaged, the stimulation sensation caused by the pressure is relatively strong, and the stimulation pain is relatively weak.

As shown in FIG. 6, a fifth embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the previous embodiment, a value range of the wrapping angle α₂ is 70°-100°, and/or a value range of the wrapping angle α₁ is 70°-100°.

In this embodiment, when the wrapping angle α₁ falls within 70°-100°, it is found that the connecting region 6 of the volute shell nose 201 and the volute shell body 202 is relatively moderate; and when the acting force F1 of the outer surface 4 of the hole-shaped part to be massaged is exerted, and the connecting region 6 is relatively larger, the acting force can be quickly conducted to the volute shell nose 201, such that the volute shell nose 201 gives rapid response and drives the volute shell body 202 to perform actions, so as to achieve smooth massage stimulation actions. Further, when the connecting region 6 between the volute shell nose 201 and the volute shell body 202 is relatively small, the acting force on the connecting end P₂ of the volute shell nose 201 will be relatively concentrated, making a portion of the volute shell nose 201 close to the connecting end P₂ is prone to bending, thereby affecting the massage stimulation effects. When the value range of the wrapping angle α₂ is relatively large, the value range of the wrapping angle α₁ will be narrowed down. Specifically, the connecting region 6 between the volute shell nose 201 and the volute shell body 202 is relatively large, making the volute shell body 202 more difficult to flip over at the connecting end P₂, such that massage blockage is formed and the massage stimulation effects are reduced.

As shown in FIGS. 10 and 11, a sixth embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the first embodiment, the volute shell nose 201 has a composite arm 2011 with a rectangular cross section;

• • the composite arm 2011 has a front arm Q₁, a rear arm Q₂, a first side arm Q₃, and a second side arm Q₄;
  • a length of a cross section of the front arm Q₁ and/or the rear arm Q₂ is L₁, a direction thereof is M₃, a thickness of the front arm Q₁ is R₁, and a thickness of the rear arm Q₂ is R₂;
  • a length of a cross section of the first side arm Q₃ and/or the second side arm Q₄ is L₂, and a thickness thereof is R₃; and
  • L₁>L₂, and the direction M₃ is perpendicular to the symmetrical plane N₂.

In this embodiment, the specific structure of the volute shell nose 201 is limited.

Specifically, the front arm Q₁ (a wall surface falling the outer surface 4 of the hole-shaped part to be massaged) and the rear arm Q₂ (a wall surface facing away from the outer surface 4 of the hole-shaped part to be massaged) serve as a wall surface where the composite arm 2011 undergoes elastic deformation. Specifically, the front arm Q₁ and the rear arm Q₂ are retracted or extended to form swinging actions of the composite arm 2011, and a swinging direction needs to be in the length direction of the wand-type massage body 1. Based on this, in order to avoid deflection of the swinging direction, the first side arm Q₃ and the second side arm Q₄ are introduced to serve as a constraining wall surface for the deformation of the composite arm 2011. Specifically, the front arm Q₁ and the rear arm Q₂ are easier to deform relative to the first side arm Q₃ and the second side arm Q by defining L₁>L₂, thereby ensuring that the swing direction of the composite arm 2011 is in the length direction of the wand-type massage body 1 rather than in the length direction perpendicular to the wand-type massage body 1, and further ensuring that the volute shell body 202 can be always attached to the outer surface 4 of the hole-shaped part to be massaged and achieve stimulation massage effects.

On the basis of the above, it is further found that: degrees of deformation of the front arm Q₁ (a wall surface falling the outer surface 4 of the hole-shaped part to be massaged) and the rear arm Q₂ (a wall surface facing away from the outer surface 4 of the hole-shaped part to be massaged) are different. Specifically, the degree of deformation of the rear arm Q₂ is relatively small, so as to prevent the composite arm 2011 from tipping over due to excessive deformation, and provide the volute shell body 202 with acting force towards the outer surface 4 of the hole-shaped part to be massaged, thereby ensuring that the volute shell body 202 is always attached to the hole-shaped part to be massaged. The degree of deformation of the front arm Q₁ is relatively large, so as to ensure that the volute shell body 202 can perform flipping actions, thereby avoiding massage stoppage due to excessive constraint of the volute shell body 202. Based on this, the thickness of the front arm Q₁ is defined as R₁ and is less than the thickness R₂ of the rear arm Q₂, and a magnitude of elastic variables is affected by forming the thickness difference, so as to achieve the above beneficial effects.

Further, the front arm Q₁ has a relatively large magnitude of elastic deformation due to its relatively smaller wall thickness, therefore, a greater degree of elastic deformation will occur to a certain extent. However, with an increase in the elastic deformation, elastic force will also increase. Specifically, the acting force on the outer surface 4 of the hole-shaped part to be massaged is correspondingly enhanced, resulting in unbalanced stimulation effects.

Based on this, the front arm Q₁ has two sets of edge regions S₃ with a thickness of R₁₁, and a central region S₄ with a thickness of R₁₂, and R₁₁=R₂=R₃, R₁₂<R₁₁.

Thus, the edge regions S₃ and the central region S₄ are divided, where the edge regions S₃ each is a region connected to the first side wall Q₃ and the second side wall Q₄, and the central region S₄ is located between the edge regions S₃. When the thickness R₁₁ of one edge region S₃ is greater than the thickness R₁₂ of the central region S₄, the magnitudes of elastic deformation of the two regions are relatively small, such that the elastic deformation is less likely to incur, facilitating the weakening of the acting force on the outer surface 4 of the hole-shaped part to be massaged due to excessive deformation of the front arm Q₁. That is, the edge region S₃ can serve as a constraint structure of the front arm Q₁, and provide a certain degree of constraint in the length direction of the wand-type massage body 1, such that the volute shell nose 201 is prevented from driving the volute shell body 202 to deviate.

On the basis of the above, a thickness of one edge region S₃ is further defined as L₁₁, and a thickness of the central region S₄ is defined as L₁₂;

• • where L₁=2*L₁₁+L₁₂;
  • further, ⅕*L₁≤L₁₂≤⅓*L₁; and
  • ¼*R₁≤R₁₂≤⅔*R₁.

When the edge region S₃ occupies a larger width on the front arm Q₁, the overall magnitude of elastic deformation of the front arm Q₁ will be reduced, that is, it is more difficult to undergo the elastic deformation, thereby weakening the acting force on the outer surface 4 of the hole-shaped part to be massaged, massage stimulation effects will be finally reduced. When the edge region S₃ occupies a smaller width on the front arm Q₁, the overall magnitude of elastic deformation of the front arm Q₁ will be increased, that is, it is relatively easy to undergo the elastic deformation, thereby resulting in a relatively low degree of constraint of the volute shell nose 201, in which case, the volute shell body 202 is easy to deviate. On this basis, Based on this, a value of the width L₁₁ of one edge region S₃ can be taken from ⅕*L₁ to ⅓*L₁, such as ⅕*L₁, ¼*L₁, ⅓*L₁, and 0.5*L₁≤L₂≤0.75*L₁; further, a value of L₂ ranges from 6 mm to 10 mm. By limiting the lengths of the front arm Q₁ and the rear arm Q₂, the acting force from 1 N to 1.5 N can be provided, since the acting force under this value is a more comfortable and acceptable force level for the human body, and based on this, it is defined that ¼*R₁≤R₁₂≤⅔*R₁, for example, a value of R₁₂ can be ¼*R₁, ⅓*R₁, or ⅔*R₁, with the aim of providing a desired degree of acting force in the foregoing range by limiting parameters such as the thickness and length of the front arm Q₁ and the rear arm Q₂.

A seventh embodiment of the present disclosure provides a volute shell-type massage structure, and on the basis of the previous embodiment, the volute shell body 202 has a mass G₁;

• • an elastic coefficient of the volute shell nose 201 acting on the center of the volute shell body 202 in the direction M₃ is T₁, and an elastic coefficient in the direction M₂ is T₂;
  • where a value range of T₁ falls within 20 N/m-35 N/m;
  • a value range of T₂ falls within 18 N/m-25 N/m; and
  • a value range of G₁ falls within 25 g-35 g.

In this embodiment, the volute shell body 202 is a flying saucer-type structure or an approximately flying saucer-type structure;

• • where a diameter ranges from 25 mm-40 mm, such as 30 mm, and 35 mm. Further, in order to avoid a large displacement of the volute shell nose 201 in the direction M₃ (this displacement will result in the deviation of the volute shell body 202 from the outer surface 4 of the hole-shaped part to be massaged, and result in decomposition and weakening of the acting force on the outer surface 4 of the hole-shaped part to be massaged), and to ensure that the volute shell nose 201 has a desired stroke difference X (2 cm-6 cm) in the direction M₂, value ranges of the elastic coefficients of the volute shell nose 201 in the directions M₃ and M₂ are defined.

When a value of T₁ is taken from 20 N/m to 35 N/m, an offset displacement of the volute shell body 202 in the direction M₃ fluctuates from 0.5 cm to 1 cm, and values within the value range is allowed, this is because when the offset displacement of the volute shell body 202 in the direction M₃ is less than 0.5 cm, a contact area between the volute shell body 202 and the outer surface 4 of the hole-shaped part to be massaged will be relatively fixed, and a position of the contact area will not change according to changes in the magnitude and direction of the acting force exerted by the outer surface 4 of the hole-shaped part to be massaged on the volute shell body 202. Apparently, the relatively fixed contact area will reduce sliding stimulation massage effects felt by the outer surface 4 of the hole-shaped part to be massaged. On the contrary, when the offset displacement of the volute shell body 202 in the direction M₃ is greater than 1 cm, the volute shell body 202 will suffer a larger amplitude of offset displacement, which will weaken the acting force on the outer surface 4 of the hole-shaped part to be massaged.

Specifically, when a value of T₂ is taken from 20 N/m to 35 N/m, the stroke difference X of the volute shell body 202 in the direction M₂ satisfies the value range of 2 cm-6 cm, such that the acting force exerted by the volute shell body 202 on the outer surface 4 of the hole-shaped portion to be massaged can provide massage stimulation effects within a desired value range (1 N-1.5 N).
