Description

Technical Field

[0001] This utility model relates to the field of daily necessities, and in particular to a massager. Background Technology

[0002] With the fast pace of life and advancements in technology, massagers are becoming increasingly common and diverse. They not only help people relax their bodies but also aid in rehabilitation and physical therapy. Embedded massagers are devices that allow body parts to be inserted for massage. Because they provide comprehensive coverage of the body part (the area to be massaged), they offer a superior massage effect.

[0003] Current embedded massagers, while enveloping the massaged body, also allow for pushing, pulling, and friction, causing vasodilation and providing exceptional comfort. Some embedded massagers can even clamp the massaged body, further enhancing the user experience. However, existing embedded massagers cannot clamp the massaged body before pushing, pulling, and rubbing, thus requiring further optimization and improvement. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a massager, comprising a soft rubber inner liner and a massage component. The soft rubber inner liner has an opening for inserting a massaged object. The massage component is disposed outside the soft rubber inner liner and connected to a drive component. The drive component is used to drive the massage component to move axially within the soft rubber inner liner. During the movement, the massage component causes the inner diameter of the soft rubber inner liner to change, thereby gradually clamping or releasing the massaged object. Furthermore, after clamping the massaged object, the massage component pushes and pulls the soft rubber inner liner.

[0005] Furthermore, in order to better realize this utility model, it also includes:

[0006] A seat body is fitted over the soft rubber inner liner and connected to the soft rubber inner liner. An annular mounting cavity is formed between the seat body and the soft rubber inner liner. In the axial direction of the annular mounting cavity, the annular mounting cavity consists of a flared area, a connecting area, and a constricted area in sequence. The flared area is located on the side closer to the opening.

[0007] The massage component is sleeved on the outside of the soft rubber inner liner and slidably mounted in the annular mounting cavity along the axial direction;

[0008] When the massage component is placed in the flared area, the massage component releases the soft rubber inner liner;

[0009] As the massage component moves in the connecting area toward the constricted area, the massage component gradually retracts inward so that the soft rubber inner liner gradually clamps the object to be massaged placed therein.

[0010] When the massage component moves in the constricted area, it pushes or pulls the soft rubber inner liner along the axial direction of the annular mounting cavity to massage the clamped object being massaged through the soft rubber inner liner.

[0011] Furthermore, to better realize this utility model, the massage component includes a ring with a connecting portion and a movable member with an extension portion. The ring is fitted over the soft rubber inner liner. The connecting portion is connected to the drive component. The movable member is placed between the ring and the soft rubber inner liner and is at least in contact with the soft rubber inner liner. The extension portion protrudes radially from the movable member along the annular mounting cavity. The ring has a through hole, and the extension portion is slidably inserted into the through hole.

[0012] The seat includes a cylindrical body fitted outside the ring. The cylindrical body has a variable diameter wall. The end of the extended portion away from the movable part abuts against the variable diameter wall. The variable diameter wall includes a first section, a second section, and a third section that are smoothly connected. The first section, the second section, and the third section form the flared area, the connecting area, and the constricted area with the soft rubber liner, respectively. The distance between the first section and the soft rubber liner is greater than that between the third section and the second section. The distance between the second section and the soft rubber liner gradually decreases from the first section to the third section.

[0013] Furthermore, in order to better realize this utility model, the movable component includes:

[0014] The board body includes a first board surface near the soft rubber inner liner and a second board surface near the ring, and the protrusion is disposed on the second board surface of the board body;

[0015] A first rolling element is rotatably mounted on the plate, and the first rolling element protrudes at least from the first surface of the plate.

[0016] Furthermore, in order to better realize this utility model, the extended portion includes:

[0017] A slider is connected to the second plate surface of the plate body, and the slider is slidably inserted into the through hole;

[0018] The second rolling element is rotatably mounted on the slider. The second rolling element and the plate are located on opposite sides of the slider, and the second rolling element abuts against the variable diameter wall.

[0019] Furthermore, in order to better realize this utility model, the cylinder wall is also provided with a side plate located on the side of the variable diameter wall, and the side plate is provided on both sides of the variable diameter wall. A track is formed between the side plates on both sides of the variable diameter wall, and the second rolling element is rolled in the track.

[0020] Furthermore, in order to better realize this utility model, the second plate surface of the plate body is also provided with a guide post extending radially along the annular mounting cavity, the annulus is provided with a guide hole, and the guide post is slidably inserted into the guide hole.

[0021] Furthermore, to better realize this utility model, the base also includes:

[0022] An end cap is provided. The end of the cylindrical body near the opening is the first end, and the other end of the cylindrical body is the second end. The end cap is closed on the first end of the cylindrical body, and the end cap has a through hole. The soft rubber liner passes through the through hole. The end cap is connected to the soft rubber liner. The other end of the cylindrical body is provided with a lug.

[0023] A slide rod extends axially along the annular mounting cavity, the slide rod connects the lug and the end cap, the annulus is provided with a sliding hole, and the slide rod is slidably inserted into the sliding hole.

[0024] Furthermore, in order to better realize this utility model, the soft rubber inner liner includes an inlet and a channel portion with an internal channel. The opening is opened in the inlet, the ring is sleeved outside the channel portion, and the channel portion passes through the through hole of the end cap. The end cap is connected to the inlet and the end cap is also connected to an outer shell covering the channel portion and the cylinder body.

[0025] The drive assembly includes a motor, a connecting plate, and a connecting rod. The motor is installed inside the housing. The connecting plate is rotatably connected to the motor's shaft. The connecting plate is also rotatably connected to one end of the connecting rod via a round shaft. The round shaft is eccentrically positioned to the motor's shaft. The other end of the connecting rod has a hinge hole. The connecting part has a hinge shaft, which is rotatably inserted into the hinge hole.

[0026] Furthermore, in order to better realize this utility model, the end cap is also connected to a protective cover covering the entrance.

[0027] Furthermore, in order to better realize this utility model, the number of the movable parts is multiple, and the multiple movable parts are evenly distributed around the soft rubber inner liner.

[0028] Furthermore, in order to better realize this utility model, the other end of the soft rubber liner is sealed.

[0029] The beneficial effects of this invention are reflected in the fact that the soft rubber inner liner not only encloses the object to be massaged, but also, during a massage stroke, utilizes the contraction and expansion of the massage components during sliding to drive the soft rubber inner liner to clamp or release the object to be massaged. After clamping the object, the inner liner can be pushed and pulled, allowing it to massage the clamped object. In addition to the aforementioned massage stimulation, when the massage components clamp the soft rubber inner liner and continue moving forward in this state, the inner liner, due to its elasticity, will be stretched. When the massage components clamp the inner liner, the clamping part acts as a sealed end. When the object to be massaged is inserted into the inner liner, a sealed end is naturally formed between the object and the opening of the inner liner. During subsequent movement, the inner liner stretches, creating a slight negative pressure between the two sealed ends, which stimulates the object to be massaged. In other words, within the same massage stroke of this application, multiple stimulations—clamping, friction, and negative pressure—are achieved for the object to be massaged.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] like Figures 1-13 As shown, the massager provided in this embodiment includes a soft rubber inner shell 100 and a massage component 300, wherein:

[0051] The soft rubber inner liner 100 has a hollow structure with an opening at one end for inserting the massage object. Optionally, the soft rubber inner liner 100 can be made of silicone, thermoplastic elastomer (TPE), or polyurethane. In use, the massage object is inserted into the inner cavity of the soft rubber inner liner 100 through the opening, and the soft rubber inner liner 100 then encloses the inserted massage object. More preferably, several pleats or fine lines can be provided on the inner wall of the soft rubber inner liner 100 to further enhance the experience of the massage object being enclosed by the soft rubber inner liner 100.

[0052] The massage component 300 is disposed outside the soft rubber inner liner 100. The massage component 300 is connected to a drive component 400. The drive component 400 is used to drive the massage component 300 to move axially in the soft rubber inner liner. During the movement, the massage component 300 drives the inner diameter of the soft rubber inner liner 100 to change, so that the soft rubber inner liner 100 gradually clamps or releases the object to be massaged. After clamping the object to be massaged, the massage component 300 pushes and pulls the soft rubber inner liner 100.

[0053] The massager also includes a base 200, which is fitted over a soft rubber inner liner 100 and connected to the inner liner 100. It should be noted that "connected" here means that the soft rubber inner liner 100 will not detach from the base 200 during use; the specific connection method will be further described below. An annular mounting cavity is formed between the base 200 and the soft rubber inner liner 100. This annular mounting cavity surrounds the soft rubber inner liner 100 and is located inside the base 200. Along its axial direction, the annular mounting cavity consists of a flared area 700, a connecting area 800, and a constricted area 900, with the flared area 700 located near the opening.

[0054] The massage component 300 is slidably mounted in the annular mounting cavity, sliding in the axial direction of the annular mounting cavity. The massage component 300 is fitted over the soft rubber inner liner 100, thus slidably positioned between the soft rubber inner liner 100 and the seat 200. Optionally, the massage component 300 is at least in contact with the soft rubber inner liner 100. When the drive component 400 operates, it drives the massage component 300 to move axially within the annular mounting cavity, thereby causing the massage component 300 to move back and forth between the flared region 700, the connecting region 800, and the constricted region 900.

[0055] When the massage component 300 is placed in the flared area 700, it unfolds to release the soft rubber inner liner 100. As the massage component 300 moves from the connecting area 800 towards the constricted area 900, it gradually retracts inward, causing the soft rubber inner liner 100 to gradually clamp the object to be massaged within it. When the massage component 300 reaches the end of the connecting area 800 and / or the beginning of the constricted area 900, its retraction reaches its maximum, thus maximizing the pressure applied by the massage component 300 to the soft rubber inner liner 100, thereby clamping the object to be massaged within it and achieving a clamping stimulation. When the massage component 300 moves in the constricted area 900, it pushes or pulls the soft rubber inner liner 100 axially along the annular mounting cavity. The inner liner 100 is used to rub against the clamped massage object. Due to the elasticity of the inner liner 100, it will stretch when clamped by the massage component 300 and as the massage component 300 continues to move forward. When the massage component 300 clamps the inner liner 100, the inner liner 100 and the clamped part of the massage object are tightly pressed together to form a sealed end. When the massage object is inserted into the inner liner 100, a sealed end will naturally form between the massage object and the opening of the inner liner 100. When it continues to move forward after clamping, the inner liner 100 is stretched, forming a slight negative pressure. This negative pressure can stimulate the massage object. Therefore, in this process, the massage object not only achieves stretching stimulation in the clamped state, but also achieves negative pressure stimulation.

[0056] Additionally, it should be noted that during engineering implementation, when the massage component 300 clamps the soft rubber inner liner 100 and continues to move forward, the massage component 300 and the soft rubber inner liner 100 are not necessarily strictly clamped without any relative displacement. The massage component 300 and the soft rubber inner liner 100 may also slide within an acceptable range. However, this sliding is not an intentional design and is generally due to engineering errors during engineering implementation. Therefore, as long as the massage component 300 clamps the soft rubber inner liner 100 and performs telescopic movements in the clamped state, it is within the protection scope of this application.

[0057] In use, firstly, the driving component 400 drives the massage component 300 to be placed in the flared area 700, so that the massage component 300 is fully expanded, thereby releasing the soft rubber inner liner 100 and allowing the soft rubber inner liner 100 to be in its natural state. Then, the object to be massaged is inserted into the soft rubber inner liner 100 through the opening. At this time, the soft rubber inner liner 100 covers the object to be massaged. Then, the driving component 400 drives the massage component 300 from the flared area 700 to the connecting area 800, and places the massage component 300 in the connecting area 800 and moves towards the narrowing area 900. During this process, the massage component 300 gradually closes inward, thereby gradually squeezing the soft rubber inner liner 100 so that the soft rubber inner liner 100 gradually clamps the object to be massaged inside. When the massage component 300 moves to the end of the connecting area 800, the massage component 300 reaches its maximum degree of closure. The maximum compressive force is applied to the outer wall of the soft rubber inner liner 100, causing the soft rubber inner liner 100 to clamp the massage object placed inside. Then, the driving component 400 drives the massage component 300 to move from the connecting area 800 to the constricted area 900, and the massage component 300 moves in the constricted area 900. At this time, the massage component 300 is fully closed, and the soft rubber inner liner 100 clamps the massage object placed inside. Therefore, when the massage component 300 moves in the constricted area 900, the massage component 300 will push or pull the soft rubber inner liner 100 along the axial direction of the annular mounting cavity, so that the soft rubber inner liner 100 rubs against the clamped massage object. During the pushing and pulling process, the soft rubber inner liner 100 will deform, thereby forming a negative pressure with pressure changes inside the soft rubber inner liner 100. When the movement reaches the maximum stroke of the constricted area 900, the massage component 300 performs a reverse movement.

[0058] Note that when the drive assembly 400 drives the massage assembly 300 to move in the constricted area 900 towards the side away from the connecting area 800, the massage assembly 300 pulls the soft rubber inner liner 100. Because the soft rubber inner liner 100 is soft and clamped, the massage assembly 300 stretches the soft rubber inner liner 100 when it is pulled. When the drive assembly 400 drives the massage assembly 300 to move in the constricted area 900 towards the side closer to the connecting area 800, the massage assembly 300 pushes the stretched soft rubber inner liner 100, causing it to retract to its original length. During the stretching process of the soft rubber inner liner 100, a negative pressure is formed inside the soft rubber inner liner 100, and when the soft rubber inner liner 100 retracts to its original length, the internal air pressure returns to normal. When the massage component 300 moves to the flared area 700, the seal between the soft rubber inner liner 100 and the body to be massaged is released, and the internal air pressure of the soft rubber inner liner 100 is the same as the external atmospheric pressure.

[0059] Optionally, the other end of the soft rubber inner liner 100 is open. In this case, when the negative pressure is formed, the pressure between the clamping part and the other end of the soft rubber inner liner 100 is normal pressure. As another embodiment of this invention, the other end of the soft rubber inner liner 100 is sealed. In this case, when the negative pressure is formed, a positive pressure is formed between the clamping part and the other end of the soft rubber inner liner 100, thereby better stimulating and massaging the massage body.

[0060] Optionally, in this embodiment, the flared region 700, connecting region 800, and constricted region 900 are three regions with different inner diameters. The inner diameter of the flared region 700 is larger than that of the constricted region 900, while the inner diameter of the connecting region 800 gradually decreases from the flared region 700 to the constricted region 900. In this embodiment, the massage component 300 includes a ring 310 and a movable component 320. The seat 200 includes a cylindrical body 210 that fits around the ring 310. The ring 310 fits around the soft rubber inner liner 100. Thus, the seat 200 is also equivalent to fitting around the soft rubber inner liner 100. That is, from the inside out, the components are the soft rubber inner liner 100, the ring 310, and the cylindrical body 210.

[0061] The aforementioned movable component 320 is positioned between the ring 310 and the soft rubber inner liner 100. The movable component 320 is at least in contact with the soft rubber inner liner 100. Thus, from the inside out, the components are: soft rubber inner liner 100, movable component 320, ring 310, and cylinder 210. The ring 310 has a connecting portion 311, which connects to the aforementioned drive assembly 400. Specifically, the connecting portion 311 can be an integrally formed or bolted-on convex plate or convex strip to the end face of the ring 310, or it can be a lifting ring welded to the end face of the ring 310, etc., as long as it can achieve connection with the aforementioned drive assembly 400. The movable part 320 is provided with an extension 330, which extends radially out of the movable part 320 along the annular mounting cavity. The ring 310 has a through hole that penetrates the side wall of the ring 310 radially. The extension 330 is slidably inserted into the through hole. In this way, the movable part 320 and the extension 330 can slide synchronously and at the same speed in the radial direction of the annular mounting cavity. In this embodiment, the expansion and contraction of the massage component 300 are accomplished by the movable member 320. Specifically, when the movable member 320 moves to the position closest to the ring 310 (or when the movable member 320 moves to be in contact with the ring 310), the massage component 300 is in a fully expanded state; when the movable member 320 moves to the position farthest from the ring 310 (or when the movable member 320 moves to the position closest to the central axis of the soft rubber inner liner 100), the massage component 300 is in a fully contracted state; when the movable member 320 moves between the ring 310 and the soft rubber inner liner 100, the massage component 300 gradually contracts or gradually expands.

[0062] The cylindrical body 210 has a variable diameter wall 211 on its wall, and the end of the extended portion 330 facing away from the movable member 320 abuts against the variable diameter wall 211. The variable diameter wall 211 includes a first section 2111, a second section 2112, and a third section 2113 that are smoothly connected. The first section 2111, the second section 2112, and the third section 2113 form a flared area 700, a connecting area 800, and a constricted area 900 with the soft rubber inner liner 100, respectively. The distance between the first section 2111 and the soft rubber inner liner 100 is greater than that between the third section 2113 and the second section 2112. The distance between the second section 2112 and the soft rubber inner liner 100 gradually decreases from the first section 2111 to the third section 2113. This makes the inner diameter of the flared area 700 greater than that of the constricted area 900, and also makes the inner diameter of the connecting area 800 gradually decrease from the flared area 700 to the constricted area 900.

[0063] When the massage component 300 is placed in the flared area 700, the end of the extension 330 away from the movable member 320 abuts against the inner wall of the first section 2111. At this time, the extension 330 and the movable member 320 move to the outermost position, and the movable member 320 is in contact with the soft rubber inner liner 100 and the ring 310. At this time, the soft rubber inner liner 100 is in a naturally expanded state, that is, the movable member 320 does not apply pressure to the outer wall of the soft rubber inner liner 100, and the massage component 300 is in a fully unfolded state.

[0064] When the massage component 300 is placed in the connecting area 800, the end of the extension 330 away from the movable member 320 abuts against the inner wall of the second section 2112. Because the distance between the second section 2112 and the soft rubber inner liner 100 gradually decreases from the first section 2111 to the third section 2113, when the massage component 300 moves in the connecting area 800 toward the narrowing area 900, the second section 2112 will gradually press the extension 330 inward, thereby causing the movable member 320 connected to the extension 330 to gradually move toward the side away from the ring 310 (that is, gradually toward the side where the soft rubber inner liner 100 is located), thereby using the movable member 320 to gradually press the soft rubber inner liner 100 inward, so that the soft rubber inner liner 100 gradually clamps the massage object placed therein. When the massage component 300 moves from the connecting area 800 toward the flared area 700, the second section 2112 will gradually release the extension 330. Based on the elasticity of the soft rubber inner liner 100, the extension 330 and the movable part 320 connected thereto will gradually move toward the side closer to the ring 310, so that the squeezing force applied by the movable part 320 on the soft rubber inner liner 100 will gradually decrease, thereby gradually releasing the soft rubber inner liner 100, and then gradually releasing the massage object clamped by the soft rubber inner liner 100.

[0065] When the massage component 300 is placed in the constricted area 900, the end of the protrusion 330 facing away from the movable member 320 abuts against the inner wall of the third section 2113. At this time, the protrusion 330 and the movable member 320 move to the innermost position, that is, the movable member 320 is in contact with the soft rubber inner liner 100, but the distance between the movable member 320 and the ring 310 reaches its maximum. At this time, the squeezing force applied by the movable member 320 on the outer wall of the soft rubber inner liner 100 reaches its maximum, thereby making the soft rubber inner liner 100 clamp the massage object placed therein. When the massage component 300 moves in the constricted area 900, because the soft rubber inner liner 100 is pressed against the massage object by the movable member 320, the moving movable member 320 will push or pull the soft rubber inner liner 100, causing the soft rubber inner liner 100 to rub against the outer wall of the massage object, and generating negative pressure with pressure changes inside the soft rubber inner liner 100.

[0066] The aforementioned cylindrical body 210 can be a straight cylinder, with a variable-diameter wall 211 forming a portion of the cylinder wall. Alternatively, the aforementioned cylindrical body 210 can be a stepped cylinder. In this case, the portion corresponding to the constricted region 900 and the portion corresponding to the flared region 700 are straight cylinders, while the portion corresponding to the connecting region 800 is a conical cylinder. In this case, the variable-diameter wall 211 can be considered the entire cylinder wall of the aforementioned cylindrical body 210.

[0067] The aforementioned flared area 700, connecting area 800, and constricted area 900 are three areas with different inner diameters. These, along with the ring 310, movable part 320, and extension 330, enable clamping, releasing, pushing, and pulling of the soft rubber inner liner 100. In another embodiment, the flared area 700, connecting area 800, and constricted area 900 can be set to arbitrary inner diameters. That is, the flared area 700, connecting area 800, and constricted area 900 are simply three different areas along the movement path of the massage component 300. In this case, the massage component 300 can include an annular support connected to the drive component 400 and a magnetostrictive film mounted on the annular support. The magnetostrictive film adheres to the soft rubber inner liner 100, generating a smaller magnetic field or no magnetic field in the flared area 700, a larger magnetic field in the constricted area 900, and a gradually increasing magnetic field in the connecting area 800 from the flared area 700 to the constricted area 900. Utilizing the principle of magnetostriction, when the annular support is placed in the flared area 700, a small or zero magnetic field causes the magnetostrictive film to extend inward to a small extent or not at all. This slight inward extension or non-extension of the magnetostrictive film applies a small or no compressive force to the soft rubber inner liner 100, thereby causing the massage component 300 to release the soft rubber inner liner 100. When the annular support is placed in the connecting area 800 and moves towards the constricted area 900, the gradually increasing magnetic field causes the magnetostrictive film to extend inward to a gradually greater extent. This causes the force of the magnetostrictive film squeezing the soft rubber inner liner 100 to gradually increase. When the annular support moves to the end of the connecting region 800, the magnetic field in the connecting region 800 reaches its maximum value, equal to the magnetic field in the constricted region 900. This maximizes the force of the magnetostrictive film squeezing the soft rubber inner liner 100, causing the soft rubber inner liner 100 to clamp the massage object placed inside. When the annular support moves in the constricted region 900, the larger magnetic field in the constricted region 900 causes the magnetostrictive film to extend inward to its maximum extent. The changing magnetic field in the connecting region 800 can be controlled by an electromagnet installed at a corresponding position on the base 200. By changing the magnitude of the current flowing through the electromagnet, the changing magnetic field generated by the electromagnet in the connecting region 800 can be controlled. The constricted region 900 and the flared region 700 can be fitted with permanent magnets of different magnetic strengths on the base 200.

[0068] Optionally, the movable component 320 in this embodiment includes a plate 321 and a first rolling element 322, wherein:

[0069] The plate 321 can be of any form, but preferably it is an arc-shaped plate, and the arc-shaped plate is coaxial with the ring 310, which in turn is coaxial with the soft rubber liner 100 and the seat 200. The plate 321 includes a first plate surface near the soft rubber liner 100 and a second plate surface near the ring 310, with an extension 330 provided on the second plate surface of the plate 321.

[0070] The first rolling element 322 is rotatably mounted on the plate 321, and the first rolling element 322 protrudes at least from the first surface of the plate 321. The first rolling element 322 can be a ball bearing. In this case, the plate 321 has mounting holes penetrating the first and second surfaces, and the ball bearing is mounted in the mounting holes, protruding from both the first and second surfaces of the plate 321. Alternatively, the first rolling element 322 can be a spherical roller mounted on the first surface of the plate 321 via a mounting bracket. To make the structure more compact, a preferred embodiment of this solution uses a ball bearing as the first rolling element. The ball bearing protruding from the first surface directly contacts the outer wall of the soft rubber inner liner 100, thereby pressing the soft rubber inner liner 100 inward. This causes a portion of the soft rubber inner liner 100 to protrude inward, forming a bulge. As the massage assembly 300 moves, the ball bearing also moves, changing the position of the bulge and thus better rubbing the object to be massaged.

[0071] Optionally, the aforementioned extension 330 includes a slider 331 and a second rolling element 332, wherein:

[0072] The slider 331 is adapted to the aforementioned through hole and is slidably inserted into it, meaning it can slide within the through hole. The slider 331 has a clearance fit with the hole wall, so when the drive assembly 400 moves the ring 310, the extended portion 330 moves along with the ring 310 because the slider 331 is positioned within the through hole. The slider 331 can be integrally formed on the second plate surface of the plate 321, welded to the second plate surface of the plate 321, or bolted to the second plate surface of the plate 321.

[0073] The second rolling element 332 is rotatably mounted on the slider 331. The second rolling element 332 and the aforementioned plate 321 are located on opposite sides of the slider 331, and the second rolling element 332 abuts against the aforementioned variable-diameter wall 211. This reduces the frictional force experienced by the protrusion 330 relative to the variable-diameter wall 211 during movement. Optionally, the second rolling element 332 can be a ball bearing mounted on the end face of the slider 331, or a roller mounted on the slider 331 via a mounting bracket. Preferably, the second rolling element 332 is configured as a roller.

[0074] Optionally, the cylinder wall of the cylinder 210 is also provided with a side plate 212 located on the side of the variable diameter wall 211, and the side plates 212 are provided on both sides of the variable diameter wall 211. A track is formed between the side plates 212 on both sides of the variable diameter wall 211. The second rolling element 332 is rolled in the track. The extension direction of the track is the same as the axial direction of the above-mentioned annular mounting cavity. In this way, the second rolling element 332 of the extension 330 can only roll in the track, thereby positioning and limiting the extension 330 and the movable part 320 as the ring 310 moves along its axial direction in the annular mounting cavity, thus improving stability.

[0075] Optionally, a guide post 340 extending radially along the annular mounting cavity is provided on the second plate surface of the plate 321. The ring 310 has a guide hole, and the guide post 340 is slidably inserted into the guide hole. This ensures that the plate 321 can only move radially relative to the ring 310 along the annular mounting cavity, further improving stability. Moreover, the guide post 340 is clearance-fitted with the guide hole. When the drive assembly 400 moves the ring 310, the guide post 340, positioned in the guide hole, allows the protrusion 330 and the movable member 320 to move together with the ring 310. More preferably, a screw hole is provided on the plate surface of the guide post 340 facing away from the plate 321. A screw 341 is screwed into the screw hole, and the outer diameter of the screw nut of the screw 341 is larger than the diameter of the guide hole. This limits the relative displacement between the movable member 320 and the ring 310.

[0076] In this embodiment, there is one ring 310, and the number of movable parts 320 can be one or more. When there is only one movable part 300, it can only compress a portion of the soft rubber inner liner 100. Therefore, the preferred embodiment of this embodiment is that there are multiple movable parts 320, which are evenly distributed around the soft rubber inner liner 100. For example, there can be two, three, four, five, or six movable parts 320, etc. Three movable parts 320 are evenly distributed around the soft rubber inner liner 100. There is a gap between the plates 321 of adjacent movable parts 320 so that the movable parts 320 can move radially in the annular mounting cavity. Moreover, when the massage assembly 300 is retracted, the plates 321 of the multiple movable parts 320 can wrap around and clamp the soft rubber inner liner 100 in all directions 360°, so that the soft rubber inner liner 100 can better clamp the massage object placed therein.

[0077] Optionally, the seat 200 provided in this embodiment further includes an end cap 220 and a slide bar 230, wherein:

[0078] The end of the cylindrical body 210 closest to the opening is defined as the first end, and the other end as the second end. An end cap 220 is fitted onto the first end of the cylindrical body 210, and the end cap 220 has a through hole through which a soft rubber inner liner 100 passes. The end cap 220 is connected to the soft rubber inner liner 100. Specifically, the soft rubber inner liner 100 includes an inlet portion 110 and a channel portion 120 with an internal channel. The opening is located in the inlet portion 110, and a ring 310 is fitted over the channel portion 120, which passes through the through hole of the end cap 220. The connection between the seat 200 and the soft rubber inner liner 100 is essentially the connection between the end cap 220 and the soft rubber inner liner 100. In practice, the end cap 220 can be fitted snugly against the inlet portion 110, and the channel portion 120 can be press-fitted into the through hole, or the end cap 220 can be bonded and fixed to the inlet portion 110.

[0079] The other end of the cylindrical body 210 is provided with a lug 213. The aforementioned slide rod 230 extends axially along the annular mounting cavity. The slide rod 230 connects the lug 213 and the end cap 220. The ring 310 is provided with a sliding hole, and the slide rod 230 is slidably inserted into the sliding hole. In this way, the movement of the ring 310 in the annular mounting cavity can be positioned and guided, so that the massage component 300 can only move axially within the annular mounting cavity. Specifically, a first insertion hole can be provided in the lug 213, and a second insertion hole can be provided in the end cap 220. The two ends of the slide rod 230 are respectively inserted into the first insertion hole and the second insertion hole, and the two ends of the slide rod 230 are respectively interference-fitted with the first insertion hole and the second insertion hole.

[0080] Optionally, in this embodiment, the end cap 220 is further connected to a shell 500 that covers the channel portion 120 (such as the inner liner of a jelly) and the cylindrical body 210 of the seat 200, thereby protecting the channel portion 120, the cylindrical body 210, the ring 310, the movable part 320, and the extension portion 330. The drive assembly 400 includes a motor 410, a connecting plate 420, and a connecting rod 430, wherein:

[0081] The motor 410 is installed inside the housing 500. The connecting plate 420 is rotatably connected to the shaft of the motor 410. The connecting plate 420 is also rotatably connected to one end of the connecting rod 430 via a round shaft 440. The round shaft 440 is eccentrically set to the shaft of the motor 410. At this time, the connecting plate 420 and the connecting rod 430 form a crank-connecting rod mechanism. The other end of the connecting rod 430 is provided with a hinge hole. The connecting part 311 is provided with a hinge shaft 450, which is rotatably inserted into the hinge hole. In this way, the motor 410 drives the connecting plate 420 to rotate around the shaft of the motor 410, thereby causing one end of the connecting rod 430 to rotate around the shaft of the motor 410, thereby driving the connecting part 311 to rise and fall.

[0082] Of course, the aforementioned drive assembly 400 can be an electric telescopic rod installed inside the housing 500. Additionally, a rechargeable battery and a circuit board containing a control chip are also installed inside the housing 500. A switch and a charging connector are also installed in the housing 500. The switch, charging connector, rechargeable battery, and the aforementioned motor 410 are all electrically connected to the circuit board. When the user presses the switch, the rechargeable battery supplies power to the motor 410, causing the motor 410 to operate. When the charging connector is connected to a charging cable, the rechargeable battery can be charged.

[0083] More preferably, the end cap 220 is also connected to a protective cover 600 that covers the entrance 110. When the massager is not needed, the protective cover 600 is connected to the end cap 220 to prevent the opening of the soft rubber inner liner 100 from being exposed. When massage is needed, the protective cover 600 can be removed.

[0084] Example 2:

[0085] like Figures 14 to 16 As shown, this embodiment is another implementation of embodiment 1. The technical solution provided in this embodiment is largely the same as that in embodiment 1, except that:

[0086] The aforementioned flared area 700, connecting area 800, and narrowed area 900 are set to arbitrary inner diameters; that is, the flared area 700, connecting area 800, and narrowed area 900 are simply three different areas along the movement path of the massage component 300. The massage component 300 includes an annular frame 350 sleeved outside the soft rubber inner liner 100 and multiple covering plates 360 placed between the annular frame 350 and the soft rubber inner liner 100. The annular frame 350 is connected to the aforementioned drive component 400, and a gap is formed between the annular frame 350 and the soft rubber inner liner 100. The covering plates 360 are movably placed in the aforementioned gap, and the covering plates 360 are at least in contact with the aforementioned soft rubber inner liner 100. On the side plate 212 of the covering plate 360 ​​near the annular frame 350, a plurality of positioning rods 361 extending radially along the annular mounting cavity are provided. The annular frame 350 is provided with a positioning cylinder 351, and the positioning rods 361 are slidably inserted into the positioning cylinder 351. This ensures that the covering plate 360 ​​can only move radially along the annular mounting cavity in the aforementioned gap and cannot deflect. Furthermore, after the covering plate 360 ​​and the annular frame 350 are connected, they will move together along the axial direction in the annular mounting cavity. That is, when the drive assembly 400 is running, it will drive the annular frame 350 to move the covering plate 360 ​​along its axial direction in the annular mounting cavity. At least two guide inclined plates 362 are also provided on the outer wall of the covering plate 360. The angle between the length direction of the guide inclined plate 362 and the axial direction of the annular mounting cavity is α, and the value of α is between 5 and 10°. Multiple covering plates 360 are evenly distributed around the soft rubber inner liner 100, with gaps between adjacent covering plates 360, thus forming a notched ring outside the soft rubber inner liner 100. A slide is formed between corresponding guide ramps 362 on two adjacent covering plates 360. The length direction of the slide is the axial direction of the annular mounting cavity, but one end of the slide is open and the other end is narrowed, with a smooth transition between the open and narrow ends. The open end is located on the side closer to the opening of the soft rubber inner liner 100. Two adjacent covering plates 360 are connected by two springs 370. Specifically, one spring 370 is connected to the open end, and the other spring 370 is connected to the narrowed end, thus elastically connecting two adjacent covering plates 360 together.

[0087] A fixing block 240 is installed on the inner wall of the aforementioned seat 200. The fixing block 240 is slidably placed in the aforementioned slide rail. Two rolling wheels 241 are rotatably installed on the fixing block 240. The two rolling wheels 241 respectively roll into contact with the guide ramps 362 on both sides of the slide rail. That is, one of the rolling wheels 241 on the fixing block 240 rolls into contact with the guide ramp 362 on a covering plate 360, and the other rolling wheel 241 on the fixing block 240 rolls into contact with the corresponding guide ramp 362 on another adjacent covering plate 360.

[0088] When the drive assembly 400 drives the massage assembly 300 to move axially within the annular mounting cavity, the annular frame 350 of the massage assembly 300 is connected to the drive assembly 400, the covering plate 360 ​​is connected to the annular frame 350 via the positioning rod 361, and the aforementioned fixing block 240 is fixed to the seat 200. Therefore, when the massage assembly 300 moves within the annular mounting cavity, the aforementioned slide will move relative to the aforementioned fixing block 240. Since the sides of the slide are guide ramps 362, when the massage assembly 300 moves, the fixing block 240 and its rollers 241 will be spread apart or... Release the guide ramps 362 on both sides of the slide, so that the covering plate 360 ​​is opened or closed under the action of the spring 370. That is, the massage component 300 is opened or closed during the movement in the annular mounting cavity. Specifically, when the massage component 300 moves toward the side where the opening is located, the covering plate 360 ​​is opened, thereby releasing the soft rubber inner liner 100. When the massage component 300 moves to the other side, the covering plate 360 ​​closes and clamps the soft rubber inner liner 100. During the process of continuing to move to the other side after clamping, the soft rubber inner liner 100 will be pulled, and a negative pressure will be formed inside the soft rubber inner liner 100.
