The silicone massage sleeve is connected to the motor to form an electric massage structure. A pressure-applying component is installed on the side wall of the shell. The pressure-applying component includes a movable pressure-applying body with a pressure-applying portion protruding towards the silicone massage sleeve. This pressure-applying portion contacts the outer surface of the side wall of the silicone massage sleeve to form a pressure-applying massage structure. The outer surface of the pressure-applying component protrudes outside the shell. This invention, by providing a pressure-applying component that can be gripped by hand, applies external pressure to the silicone massage sleeve, causing it to squeeze inward. Users can manually control the massage intensity during use to meet personalized needs. It also features a sound-emitting function for enhanced massage effects. This patent, however, uses vibration massage, which has a relatively poor massage effect. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing massage devices often use vibration massage, which has poor massage effect with long-term use, and excessive vibration can easily damage the massage area. Furthermore, existing massage devices cannot replace massage components or are difficult to disassemble and replace, making it difficult to maintain hygiene of the massage components for reuse, thus posing health problems. To address these shortcomings of the prior art, this invention provides a torsional massage device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A torsional massage device is constructed, comprising a cylindrical body with an upper opening and a hollow cavity inside. The massage device also includes an elastic massage element connected to the hollow cavity. The elastic massage element has an insertion end at its upper part and a massage cavity inside that accommodates the massage area. A drive assembly is connected to the lower part of the elastic massage element. The drive assembly drives the lower part of the elastic massage element to rotate back and forth within a set angle, and a speed difference is formed between the upper and lower parts of the elastic massage element to perform torsional massage.

[0007] Preferably, the insertion end is positioned above the upper opening, and the insertion end is fixedly or movably connected to the upper opening. When movably connected, the friction between the cylinder and the contact part of the elastic massage element reduces the rotational speed above the elastic massage element, thereby creating a rotational speed difference between the upper and lower parts of the elastic massage element.

[0008] Preferably, the cross-section of the cylinder is elliptical, and the elliptical shape generates a speed-delaying force on the upper part of the elastic massage element, creating a speed difference between the upper and lower parts of the elastic massage element.

[0009] Preferably, the elastic massage member has multiple sets of large protrusions arranged along the axial direction of the inner wall of the elastic massage member, and the protrusions rotate to massage the massage area when the elastic massage member is twisted.

[0010] Preferably, the large protrusion is provided with multiple sets of small protrusions, which are arranged in a regular or irregular manner. When the large protrusion is twisted, the small protrusions rub against the massage area for massage.

[0011] Preferably, a gap is provided between the inner wall of the cylinder and the outer wall of the elastic massage element, and a concave cavity is formed extending along the axial direction of the cylinder at the bottom of the cylinder. A lower opening is provided on the concave cavity, and the drive assembly seals the lower part of the gap in the concave cavity. A flared mouth is provided on the upper part of the elastic massage element, and the flared mouth contacts the upper opening to seal the upper part of the gap.

[0012] Preferably, a linkage cavity is provided below the elastic massage element, and a coupling receiving block is provided inside the linkage cavity. The driving component drives the coupling receiving block to rotate, thereby causing the lower part of the elastic massage element to rotate.

[0013] Preferably, the drive assembly includes a motor and a coupling output block driven by the motor to rotate back and forth within a set angle. The coupling output block drives the coupling receiving block to rotate back and forth within the set angle. A control board and a battery are connected below the motor. The control board is provided with a micro switch and a charging port for charging the battery.

[0014] Preferably, the coupling receiving block includes a stop plate with its radius placed inside the concave cavity. Magnets are provided on the opposite surfaces of the stop plate and the drive assembly. After the drive assembly is inserted into the concave cavity at a certain position, the drive assembly moves further into the concave cavity under the action of the magnets.

[0015] The beneficial effects of this invention are as follows: By setting a drive component below the massage piece, and fixing the upper part of the massage piece relatively, a speed difference is formed between the upper and lower parts of the massage piece within a set angle when the drive component rotates, achieving the twisting of the massage piece. During the twisting process, the massage cavity decreases from a large (initial state) to a small size due to the speed difference, generating a locking force and creating a tightening sensation in the massage area. Simultaneously, a gap is formed between the cylinder and the massage piece, allowing warm water to be injected into the gap to maintain a more suitable temperature environment for the massage, further enhancing the massage effect. Large protrusions are set on the inner wall of the massage piece, arranged regularly, and twist as the massage piece twists, further improving the effect. Multiple sets of small protrusions are set on the large protrusions; when the large protrusions twist, the small protrusions rub against the massage area, resulting in a better massage effect and a superior user experience. Furthermore, the massage device is more portable and lightweight, facilitating assembly and replacement of the massage piece, as well as disassembly and cleaning, ensuring a hygienic environment for the massage piece and a healthier massage environment.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] A preferred embodiment of this utility model provides a twisting massage device; such as... Figure 1-3 As shown, the device includes a cylindrical body 10 with openings at both the top and bottom and an internal cavity. A massage element 20 is connected inside the cylindrical body. A drive assembly 30 connected to the massage element is located at the bottom of the cylindrical body. The drive assembly causes the lower part of the massage element to rotate, while the upper part of the massage element does not rotate or rotates at a lower speed than the lower part, creating a speed difference between the upper and lower parts to form a torsion of the massage element. The massage operation is achieved through the torsion of the massage element. During the torsion, the massage element will decrease from a large (initial state) speed difference, and the internal cavity will generate a locking force, making the massage area feel tight.

[0030] Specifically, such as Figure 2-5As shown, an upper opening 101 is formed at the top of the cylinder 10, and a concave cavity 100 is formed at the bottom. A lower opening 102 is provided in the concave cavity, which is formed by the upward extension of the bottom of the cylinder. The radius of the lower opening 102 is smaller than the radius of the upper opening. The massage element 20 is inserted into the cylinder through the lower opening, and the flared end 204 is pulled out of the cylinder and connected to the upper opening, thus connecting the massage element to the cylinder. A linkage cavity 201 is provided at the lower end of the massage element, and a coupling receiving block 202 is provided in the linkage cavity. The receiving block is connected to the drive assembly 30, and the drive assembly drives the coupling receiving block 202 to rotate, thereby causing the lower part of the massage element to rotate. The drive assembly 30 includes a housing 308 and a motor 302 disposed within the housing. A control board 304 and a battery 303 are located below the motor, with a charging port 307 corresponding to the battery and control board. A micro switch 305 is located below the control board, and a button 306 is located below the housing corresponding to the micro switch. Applying pressure to the button activates the micro switch, which in turn drives the motor to rotate. A coupling output block 301 is connected above the motor shaft 309. The coupling output block rotates with the motor and drives the coupling receiving block 202 to rotate, thus enabling the motor to rotate the lower end of the massage element. It should be noted that, to ensure synchronous rotation between the coupling output block and the motor shaft, the motor shaft is non-cylindrical, and the coupling output block is prismatic with a pointed top. A corresponding coupling output block is located below the coupling receiving block, allowing the rotation of the coupling output block to drive the rotation of the coupling receiving block.

[0031] Furthermore, such as Figure 3 As shown, a gap 40 is left between the inner wall of the cylinder 10 and the outer wall of the massage element 20, allowing warm water to be poured into the gap to improve the massage environment. The upper end of the massage element has a flared opening 204, positioned at the upper opening, with the upper radius of the flared opening larger than the radius of the upper opening 101. The lower part of the flared opening has a recessed portion 207 and a protruding portion 208 connected to the recessed portion. The upper opening is positioned at the recessed portion, and the presence of the protruding portion improves the sealing at the connection between the flared opening and the upper opening. When warm water needs to be injected into the gap, the massage element is pulled to open the gap between the flared opening and the upper opening. After injecting warm water, the pulling force on the massage element is released, and the massage element deforms and returns to its original position, placing the flared opening at the upper opening and sealing it. It should be noted that because the flared opening needs to be opened, the massage element must be an elastic element with good deformation force and recovery force after deformation to facilitate the deformation of the massage element.

[0032] Furthermore, such as Figure 5-8As shown, the massage component 209 has a bottom wall that divides it into two parts: an upper part forming a massage cavity and a lower part forming a linkage cavity 201. A linkage receiving block 202 is placed inside the linkage cavity. The linkage receiving block includes a stop plate 2020 and an insertion part 2020 positioned above the stop plate. A linkage component 2023 is positioned above the insertion post. The linkage component is inserted into the linkage cavity and sealed by the insertion post and the opening of the linkage cavity. Simultaneously, a sealing ring 2021 is positioned above the stop plate. When the insertion post is inserted into the linkage cavity, the outer wall 2010 of the linkage cavity contacts the inner wall of the sealing ring 2021, and both the inner and outer walls of the sealing ring contact the inner wall of the lower opening. A portion of the sealing ring is positioned above the lower opening, thus achieving a seal at the lower opening and preventing warm water from flowing out through it, improving the sealing performance during use. To achieve better synchronous rotation between the lower part of the massage component and the linkage component, the linkage component 2023 can be integrally formed with the massage component inside the linkage cavity, or the lower end of the massage component can be rotated by the rotational friction of the linkage component during massage; or the linkage component can be provided with multiple sets of connecting holes 2025, and a connecting post 2011 can be provided in the linkage cavity corresponding to the connecting hole. Inserting the connecting post into the connecting hole can achieve synchronous rotation of the bottom of the linkage component and the massage component at the same speed; or a connecting groove 2024 can be provided on the outside of the linkage component, and the connecting post can be placed in the connecting groove to achieve synchronous rotation.

[0033] Furthermore, such as Figure 5 As shown, to enhance the massage effect, the inner wall 103 of the cylinder has an elliptical cross-section. Since the massage element is an elastic component with good deformation force, the upper end of the massage element will not rotate with the lower end when placed inside the cylinder. When the drive assembly 30 rotates the lower end of the massage element, the upper end will not rotate, thus achieving a torsional massage effect. Therefore, the flared opening can be fixedly connected to the upper end of the cylinder, or the rotational resistance generated by the ellipse can create a speed difference between the upper and lower ends of the massage element, thereby enabling the massage element to perform a torsional massage. Figure 10-11 As shown, the control panel rotates to the left to a set angle each time, and then rotates to the right, thus achieving a back-and-forth twisting massage for a better massage effect and experience. During the twisting motion, the massage chambers decrease in size due to the difference in rotation speed, generating a locking force that makes the massaged area feel tighter.

[0034] Furthermore, such as Figure 6-7 As shown, the massage cavity 203 is provided with multiple sets of large protrusions 205, which are arranged axially within the massage cavity. This axial arrangement of the large protrusions causes them to twist when the massage element is rotated, further enhancing the massage effect. Simultaneously, each set of large protrusions is provided with multiple sets of small protrusions 206, which can be arranged regularly or irregularly. When the large protrusions twist, the small protrusions provide further massage to the affected area, thereby further enhancing the massage effect.

[0035] Furthermore, such as Figure 2As shown, to facilitate the connection between the drive assembly 30 and the coupling receiving block 202, multiple sets of magnets 300 are provided below the coupling receiving block 202, and corresponding magnets 300 are also provided above the drive assembly. When the drive assembly is inserted into the concave cavity 100, after being inserted to a certain distance, the attraction of the magnets will attract the drive assembly to contact the coupling receiving block, making installation more convenient. At the same time, due to the attraction of the magnets, there is no need to worry about the drive assembly not being inserted correctly into the coupling receiving block. Simply press the button to rotate the connection output block, and the attraction of the magnets will install the drive assembly into place during the rotation.

[0036] During assembly of the massage device of this utility model, the coupling receiving block 202 with magnet 300 is inserted into the linkage cavity 201 of the massage component 20 and secured, or the coupling receiving block and the massage component are integrally formed during production. Then, the flared mouth 204 is inserted into the cylinder through the lower opening 102, and the massage component is pulled from the upper opening 101 to pull the flared mouth to the upper opening. At this time, the sealing ring is placed at the lower opening and seals the gap 40, and the baffle is placed in the concave cavity 100. The production-assembled drive component 30 with magnet is inserted into the concave cavity. When it is inserted to a certain distance, the attraction force of magnet 300 attracts the drive component to the coupling output block 301 and the coupling receiving block 202. Pressing the button makes the coupling receiving block rotate. During the rotation, when the coupling receiving block is facing the coupling output block, the attraction force of the magnet makes the drive component move forward further, so that the coupling output block is completely inside the coupling receiving block, and the assembly is completed. When it is necessary to replace the massage component, simply pull out the drive assembly and then pull the massage component out of the cylinder, making it convenient to replace and install the massage component.

[0037] When using the massage device of this utility model, pull the flared end 204 to inject warm water into the gap, then release the pull of the flared end. Insert the massage part into the massage cavity 203 through the insertion end 200. Press the button 306 to activate the micro switch 305. At this time, the motor 302 drives the motor shaft 309 to rotate back and forth at a set angle, which in turn drives the coupling output block 301 to rotate back and forth. The coupling output block drives the coupling receiving block 202 to rotate back and forth, and drives the lower part of the massage piece to rotate back and forth. Due to the elliptical inner wall or fixed connection, the upper part of the massage piece 20 has a speed difference between the upper and lower parts of the massage piece, which makes the massage piece in a back-and-forth twisting state and massage the massage part. When the massage piece twists, the large protrusions twist back and forth to massage the massage part, and at the same time, the small protrusions also rub against the massage part for massage, resulting in a better massage effect and a better experience.

[0038] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
