Description

Technical Field

[0001] This application relates to the field of health massage equipment technology, and more specifically, to an easy-to-clean massager. Background Technology

[0002] A massager is a device that simulates manual massage through mechanical or electronic means, aiming to relieve muscle fatigue and promote blood circulation. During use, the user inserts the area to be massaged into the inner wall of the massager, and then the inner wall of the inner wall squeezes and rubs the area to promote blood circulation and muscle relaxation, achieving a massage effect.

[0003] After use, the inner lining of the massager will retain the user's bodily fluids and skin debris. To prevent these residues from corroding the inner lining or breeding bacteria, they need to be washed away. However, because the internal structure of the inner lining is quite variable, the inner wall needs to be turned inside out for cleaning. Although the inner lining has a certain degree of elasticity, the stretching caused by turning it inside out can lead to excessive deformation of the inner lining. Repeated washing can cause the inner wall of the inner lining to become deformed or even break, which is difficult to recover from. Utility Model Content

[0004] The purpose of this application is to provide an easy-to-clean massager that addresses the aforementioned problems, reduces the risk of damage to the inner drum, and thus improves the situation.

[0005] This application is achieved through the following technical solution:

[0006] This application provides an easy-to-clean massager, which includes an inner liner and a sealing element. The inner liner has a massage cavity inside. The massage cavity has a first end and a second end that are arranged opposite to each other along its length. The first end has a first inlet that extends to the surface of the inner liner. The inner liner also has a flow channel. One end of the flow channel is connected to the second end, and the other end of the flow channel has a first outlet that extends to the surface of the inner liner. The line connecting the first inlet and the second end is L1, and the line connecting the first outlet and the second end is L2. The angle between L1 and L2 is α, which satisfies 180° ≥ α > 90°. The sealing element is used to block or open the first outlet.

[0007] In the technical solution of this application embodiment, the massage cavity of the existing massager has only one opening for the massage part to enter. When water is directly injected into the massage cavity to clean the inner liner, the residue may accumulate at the bottom of the massage cavity, making it difficult to flush out the residual body fluids and skin debris inside the massage cavity. Therefore, in order to clean the inner liner, the inner wall of the massage cavity needs to be turned out for cleaning. Although the inner liner has a certain elasticity, the stretching of the inner wall during the process of turning out the inner liner will cause excessive deformation of the inner liner. Repeated washing will cause the inner wall of the inner liner to undergo deformation that is difficult to recover or even break. In the inner liner of the massager provided in this application, the massage cavity has a first end and a second end arranged opposite to each other along its length. The first end is provided with a first inlet, which extends to the surface of the inner liner. A flow channel is also provided inside the inner liner. One end of the flow channel is connected to the second end, and the other end of the flow channel is provided with a first outlet, which extends to the surface of the inner liner. A sealing element is used to block or open the first outlet. During daily use, the sealing element blocks the first outlet, allowing the massage cavity to be a closed cavity, thereby improving the coverage effect of the massage cavity on the massage area. When cleaning the inner liner, the sealing element can be removed to open the first outlet, and then water or detergent can be injected into the massage cavity through the first inlet. During this period, the inner liner can be rubbed to squeeze the inner walls of the massage cavity against each other. The water or detergent will carry the residue in the massage cavity and flow from the first end to the second end, enter the flow channel, and then leave the inner liner through the first outlet. This structure allows the inner wall of the massage cavity to be turned inside out without having to turn the inner liner inside out. The massage chamber is thoroughly cleaned under the premise of reducing the risk of damage to the inner liner due to excessive stretching, thus extending the service life of the inner liner. It also eliminates the need to turn the inner wall of the massage chamber inside out and back in, reducing the difficulty of cleaning. The line connecting the first inlet and the second end is L1, and the line connecting the first outlet and the second end is L2. The angle between L1 and L2 is α. The larger α is, the more straight the overall structure formed by the massage chamber and the flow channel is. The smaller the deceleration effect caused by the change in flow direction during the process of the cleaning agent flowing from the first inlet to the first outlet, the less the deceleration effect is. When 180°≥a>90° is satisfied, the length direction of the massage chamber can be parallel to the horizontal direction during the cleaning process, making the first inlet vertically upward. On the one hand, the deceleration effect of the cleaning agent flowing inside the inner liner is weak, which allows it to carry the residue. On the other hand, the residue can move along the flow channel to the first outlet under the influence of gravity, making it less likely for the residue to accumulate inside the inner liner and easier to clean.

[0008] In some embodiments, the inner liner is elastic and thermally stable.

[0009] In the technical solution of this application embodiment, in order to improve the user experience, the massager heats the inner shell between user use. However, the inner shell of most existing massagers is made of thermoplastic elastomer (TPE). The heat distortion temperature of this material is between 50°C and 200°C. The temperature of the area directly in front of the heater will exceed 50°C, causing the thermoplastic elastomer inner shell to soften and melt due to heat, lose its original elasticity, and change its shape, resulting in damage to the inner shell. The massager's inner liner provided in this application is made of an elastic and thermally stable material (such as liquid rubber). This material allows the inner liner to withstand high temperatures without softening, deforming, or being damaged, thus extending its service life. Furthermore, when conventional electric heaters heat the massage chamber, the inner wall of the massage chamber directly in front of the heater often has a higher temperature, while the inner wall of the part farther from the heater has a lower temperature. Uneven temperature distribution within the massage chamber can lead to burns or low-temperature stimulation of the massage area, resulting in a poor user experience. The elastic and thermally stable inner liner provided in this application can be heated by injecting hot water into the massage chamber. Once the temperature of the inner liner rises, the sealing piece is opened to drain the hot water. This heating method ensures a uniform temperature of the inner wall of the massage chamber, improving the user experience, and also reduces the risk of excessively high temperatures around the heater damaging the inner liner, extending its service life. In addition, when cleaning the inner liner, boiling water can be directly injected into the massage chamber to disinfect and sterilize the inside of the massage chamber at high temperatures, improving the cleaning effect.

[0010] In some embodiments, the inner wall of the massage cavity is provided with a protruding first guide ridge; the first guide ridge extends in a spiral shape along the length direction of the massage cavity, and the first guide ridge extends from the first end to the second end.

[0011] In the technical solution of this application embodiment, the inner wall of the massage cavity is provided with a protruding first guide ridge, which increases the effect of pressure stimulation on the massage area and improves the user experience; the first guide ridge extends in a spiral shape along the length of the massage cavity, guiding the liquid entering the massage cavity to gather together relatively quickly. The first guide ridge extends from the first end to the second end, guiding the gathered liquid to flow from the first end to the second end relatively quickly, and then leave the inner liner through the flow channel, improving the cleaning efficiency of the inner liner; in addition, this structure also increases the flow rate of the liquid in the massage cavity, enhancing the flushing effect of the liquid on the residue in the massage cavity.

[0012] In some embodiments, the portion of the flow channel that connects to the first outlet is a guide section; the diameter of the guide section gradually decreases from the side near the second end to the side that connects to the first outlet.

[0013] In the technical solution of this application embodiment, the diameter of the guide section gradually decreases from the side near the second end to the side connecting to the first outlet, forming a tapered structure. This design can accelerate the fluid flow rate, allowing the liquid in the flow channel to leave the inner tank more quickly, thus improving the rinsing efficiency of the inner tank. The unidirectional flow field formed by the tapered structure can suppress backflow and deposition of dirt. The gradual reduction in diameter avoids turbulence or eddies caused by abrupt changes in cross-sectional area, reducing the possibility of residues remaining in the flow channel.

[0014] In some embodiments, the inner wall of the flow channel is provided with a protruding second guide ripple; the second guide ripple extends in a spiral shape along the length direction of the flow channel, and the second guide ripple extends from the second end to the first outlet.

[0015] In the technical solution of this application embodiment, the spiral structure of the second guide pattern forces the fluid (such as cleaning water or detergent) to rotate and flow along the inner wall of the channel, forming a centrifugal force field. The centrifugal force throws dirt particles in the fluid toward the channel wall, enhancing the stripping effect of the water flow on the residue; the second guide pattern extends spirally along the length of the channel, guiding the liquid entering the channel to gather together relatively quickly, and then flow to the first outlet under the guidance of the second guide pattern and leave the inner tank, accelerating the flow speed of the liquid in the channel and improving the cleaning efficiency of the inner tank.

[0016] In some embodiments, the number of flow channels is multiple; the multiple flow channels are arranged in a circular array around the length direction of the massage cavity.

[0017] In the technical solution of this application embodiment, multiple channels are arranged in a circumferential array around the length of the massage cavity. These channels serve as reinforcing ribs for the inner liner, and their circumferential array forms a truss-like mechanical support system, significantly improving the inner liner's resistance to deformation (especially when subjected to water flow impact or external pressure), and extending its service life. Multiple channels can disperse and discharge the water entering the massage cavity, preventing a single channel from being unable to drain the liquid from the inner liner in a timely manner when the amount of liquid is large, thereby improving the overall cleaning efficiency of the inner liner.

[0018] In some embodiments, the device further includes a housing, which is fitted over the outer side of the inner liner; the housing is provided with a second inlet and a second outlet; the first inlet is connected to the second inlet, and the first outlet is connected to the second outlet.

[0019] In the technical solution of this application embodiment, the outer shell is fitted onto the outside of the inner liner, forming a double-layer structure that effectively resists deformation caused by accidental collisions or drops, protects the internal massage components from external damage, and extends the service life of the device. The second inlet of the outer shell is connected to the first inlet of the inner liner, and the second outlet is connected to the first outlet of the inner liner, forming a complete cleaning fluid circulation path. Users can directly inject cleaning fluid through the second inlet of the outer shell, allowing it to flow through the inner liner's channels and then drain, achieving deep cleaning of the inner liner without the hassle of disassembling it.

[0020] In some embodiments, the first inlet of the inner liner extends out of the outer shell through the second inlet, and the inner liner is sealed to the inner wall of the second inlet.

[0021] In the technical solution of this application embodiment, the first inlet of the inner liner extends out of the outer shell through the second inlet, forming an independent cleaning interface. The cleaning fluid can enter the inner liner without flowing through the interior of the outer shell, reducing the risk of damage to the outer shell due to liquid erosion. The inner liner and the inner wall of the second inlet are sealed together, completely isolating the space between the inner liner and the outer shell from the outside. Even if the outer shell surface is contaminated with pollutants, they will not enter the space between the inner liner and the outer shell through the second inlet, meeting the hygiene standards for medical-grade equipment. The second inlet, through its sealed connection with the inner liner, can limit the deformation of the portion of the inner liner connected to it, preventing excessive deformation at the first inlet of the inner liner from losing the squeezing and massaging effect on the massage area, ensuring a continuous and stable massage effect from the inner liner on the massage area.

[0022] In some embodiments, the outer shell is provided with a first cover; the first cover is used to block the second inlet, and the first cover covers the inner liner extending out of the outer shell.

[0023] In the technical solution of this application embodiment, when the massager is idle, the first cover blocks the second inlet, and the first cover covers the inner liner that extends out of the outer shell, effectively preventing dust, liquid or insects from entering the inner liner, which meets the hygiene standards of medical-grade equipment.

[0024] In some embodiments, the outer shell is further provided with a second cover; the second cover is used to block the second outlet; a sealing member is provided on the second cover; the second cover is also provided with a limiting groove for fixing the inner liner, and the sealing member is located at the center of the limiting groove.

[0025] In the technical solution of this application embodiment, the sealing component is disposed on the second cover. The user can control the opening and closing of the first outlet through the cover without separately disassembling the inner liner, reducing the preparation time required for cleaning the inner liner. The second cover is also provided with a limiting groove for fixing the inner liner. The sealing component is located at the center of the limiting groove. The limiting groove and the sealing component cooperate to restrict the position of the first outlet, thereby allowing the flow channel to remain straight. This prevents the flow channel from being bent for a long time due to inner liner deformation, which would make it difficult for the flow channel to return to a straight state on its own, thus hindering the flow of liquid out of the inner liner.

[0026] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0040] According to some embodiments of this application, optionally, such as Figures 2-5As shown, this application provides an easy-to-clean massager, which includes an inner liner 1 and a sealing member 230. The inner liner 1 has a massage cavity 10 inside. The massage cavity 10 has a first end 11 and a second end 12 arranged opposite to each other along its own length direction. The first end 11 is provided with a first inlet 110, which extends to the surface of the inner liner 1. The inner liner 1 also has a flow channel 13 inside. One end of the flow channel 13 is connected to the second end 12, and the other end of the flow channel 13 is provided with a first outlet 130, which extends to the surface of the inner liner 1. The line connecting the first inlet 110 and the second end 12 is L1, and the line connecting the first outlet 130 and the second end 12 is L2. The included angle between L1 and L2 is α, which satisfies that 180°≥α>90°. The sealing member 230 is used to block or open the first outlet 130.

[0041] The inner liner 1 can be made of a soft, skin-friendly and elastic material, such as silicone, latex, thermoplastic elastomer (TPE), etc.

[0042] The diameter of the flow channel 13 is not larger than the diameter of the massage cavity 10, so as to avoid the opening of the connection between the massage cavity 10 and the flow channel 13 being too large and affecting the coverage effect of the massage cavity 10 on the massage area.

[0043] The first entrance 110 is the opening through which the massage area enters the inner bladder 1.

[0044] The first outlet 130 is the opening through which cleaning liquid and residues inside the inner liner 1 leave the inner liner 1.

[0045] The sealing element 230 can be detachably connected to the inner liner 1. A portion of the sealing element 230 can extend into the first outlet 130 and fit against the inner wall of the first outlet 130, increasing the contact area between the sealing element 230 and the first outlet 130 to enhance the sealing effect of the sealing element 230 on the first outlet 130.

[0046] The massage chamber 10 of the existing massager has only one opening for the massage area to enter. When water is poured directly into the massage chamber 10 to clean the inner tank 1, residues may accumulate at the bottom of the massage chamber 10, making it difficult to flush out residual body fluids and skin debris inside the massage chamber 10. Therefore, in order to clean the inner tank 1, the inner wall of the massage chamber 10 needs to be turned inside out for cleaning. Although the inner tank 1 has a certain degree of elasticity, the stretching caused by turning the inner wall of the inner tank 1 inside out will lead to excessive deformation of the inner tank 1. Repeated washing will cause the inner wall of the inner tank 1 to undergo deformation that is difficult to recover or even break. In the inner liner 1 of the massager provided in this application, the massage cavity 10 has a first end 11 and a second end 12 arranged opposite to each other along its own length direction; the first end 11 is provided with a first inlet 110, which extends to the surface of the inner liner 1; a flow channel 13 is also provided inside the inner liner 1; one end of the flow channel 13 is connected to the second end 12, and the other end of the flow channel 13 is provided with a first outlet 130, which extends to the surface of the inner liner 1; a sealing member 230 is used to seal or open the first outlet 130. During daily use, the sealing member 230 seals the outlet. The first outlet 130 allows the massage cavity 10 to be a closed cavity, thereby improving the coverage effect of the massage cavity 10 on the massage area. When cleaning the inner tank 1, the sealing piece 230 can be removed to open the first outlet 130, and then water or cleaning agent can be injected into the massage cavity 10 through the first inlet 110. During this period, the inner tank 1 can be rubbed to make the inner walls of the massage cavity 10 squeeze each other. The water or cleaning agent will carry the residue in the massage cavity 10 and flow from the first end 11 to the second end 12, enter the flow channel 13, and then leave the inner tank 1 through the first outlet 130. The structure allows for cleaning of the massage cavity 10 without having to turn the inner wall of the inner liner 1 inside out, reducing the risk of damage from excessive stretching and extending the service life of the inner liner 1. It also eliminates the need to turn the inner wall of the massage cavity 10 inside out and back out, reducing cleaning difficulty. The line connecting the first inlet 110 and the second end 12 is L1, and the line connecting the first outlet 130 and the second end 12 is L2. The angle between L1 and L2 is α. The larger α is, the more straight the overall structure formed by the massage cavity 10 and the flow channel 13 becomes. The cleaning agent flows from the first inlet... The less the deceleration effect caused by the change in flow direction occurs when the cleaning agent flows to the first outlet 130, the less it will be. When 180°≥a>90° is satisfied, the length direction of the massage cavity 10 can be parallel to the horizontal direction during the cleaning process, so that the first inlet 110 is vertically upward. On the one hand, the deceleration effect of the cleaning agent is weak when it flows inside the inner tank 1, so that it can carry the residue and move. On the other hand, the residue can move along the flow channel 13 to the first outlet 130 under the influence of gravity, so that the residue is not easy to accumulate inside the inner tank 1 and is easier to clean.

[0047] According to some embodiments of this application, optionally, the inner liner 1 is elastic and has thermal stability.

[0048] The material of the inner liner 1 can be, but is not limited to, liquid silicone. For example, liquid silicone has a heat distortion temperature of up to 150℃, which is difficult to achieve in daily use.

[0049] To enhance the user experience, the massager heats the inner chamber 1 between uses. However, most existing massagers' inner chambers 1 are made of thermoplastic elastomer (TPE), a material with a heat distortion temperature between 50°C and 200°C. The temperature in the area directly in front of the heater exceeds 50°C, causing the TPE inner chamber 1 to soften and melt due to heat, losing its original elasticity and changing shape, ultimately leading to damage. In contrast, the massager's inner chamber 1 provided in this application is made of an elastic and thermally stable material (such as liquid rubber). This material allows the inner chamber 1 to withstand higher temperatures without softening, deforming, or being damaged, extending its lifespan. Furthermore, when conventional electric heaters heat the massage cavity 10, the inner wall of the massage cavity 10 is often hotter in the area directly in front of the heater than in the area further away. This uneven temperature distribution can cause burns or low-temperature stimulation to the massage area, resulting in a poor user experience. The massager provided in this application uses an elastic and thermally stable material... The thermally stable inner liner 1 can be heated by injecting hot water into the massage chamber 10. Once the temperature of the inner liner 1 rises, the sealing piece 230 is opened to drain the hot water from the massage chamber 10. This heating method ensures a uniform temperature on the inner wall of the massage chamber 10, improving the user experience. It also reduces the risk of damage to the inner liner 1 due to excessively high temperatures around the heater, extending the service life of the inner liner 1. Furthermore, when cleaning the inner liner 1, boiling water can be directly injected into the massage chamber 10 to sterilize the inside of the massage chamber 10 at high temperatures, improving the cleaning effect of the inner liner 1.

[0050] According to some embodiments of this application, optionally, the inner wall of the massage cavity 10 is provided with a protruding first guide ridge; the first guide ridge extends in a spiral shape along the length direction of the massage cavity 10, and the first guide ridge extends from the first end 11 to the second end 12.

[0051] The first guide ridge can be a straight line extending along the length of the massage cavity 10.

[0052] The first guide wave can rise and fall towards the center of the massage cavity 10, making the stimulation effect on the user more varied and improving the user experience.

[0053] The inner wall of the massage cavity 10 is provided with a protruding first guide groove, which increases the pressure stimulation effect on the massage area and improves the user experience. The first guide groove extends in a spiral shape along the length of the massage cavity 10, guiding the liquid entering the massage cavity 10 to gather together more quickly. The first guide groove extends from the first end 11 to the second end 12, guiding the gathered liquid to flow from the first end 11 to the second end 12 more quickly, and then leave the inner tank 1 through the flow channel 13, improving the cleaning efficiency of the inner tank 1. In addition, this structure also increases the flow rate of the liquid in the massage cavity 10, enhancing the flushing effect of the liquid on the residue in the massage cavity 10.

[0054] According to some embodiments of this application, optionally, such as Figure 5 As shown, the portion of the flow channel 13 that connects to the first outlet 130 is a guide section 131; the diameter of the guide section 131 gradually decreases from the side near the second end 12 to the side that connects to the first outlet 130.

[0055] The inner wall of the guide section 131 can be an arc surface.

[0056] The diameter of the guide section 131 gradually decreases from the side near the second end 12 to the side connecting to the first outlet 130, forming a tapered structure. This design can accelerate the fluid flow rate, allowing the liquid in the flow channel 13 to leave the inner tank 1 more quickly, thus improving the rinsing efficiency of the inner tank 1. The unidirectional flow field formed by the tapered structure can inhibit backflow and deposition of dirt. The gradually decreasing diameter avoids turbulence or eddies caused by abrupt changes in cross-sectional area, reducing the possibility of residues remaining in the flow channel 13.

[0057] According to some embodiments of this application, optionally, the inner wall of the flow channel 13 is provided with a protruding second guide ripple; the second guide ripple extends in a spiral shape along the length direction of the flow channel 13, and the second guide ripple extends from the second end 12 to the first outlet 130.

[0058] The second guide pattern can be a straight line texture extending along the length of the flow channel 13.

[0059] The second guide ripple can be set continuously with the first guide ripple.

[0060] The spiral structure of the second guide pattern forces the fluid (such as cleaning water or detergent) to rotate and flow along the inner wall of the channel 13, forming a centrifugal force field. The centrifugal force throws dirt particles in the fluid toward the wall of the channel 13, enhancing the stripping effect of the water flow on the residue; the second guide pattern extends spirally along the length of the channel 13, guiding the liquid entering the channel 13 to gather together relatively quickly, and then flow to the first outlet 130 under the guidance of the second guide pattern and leave the inner tank 1, accelerating the flow speed of the liquid in the channel and improving the cleaning efficiency of the inner tank 1.

[0061] According to some embodiments of this application, optionally, such as Figures 1-3 and Figure 5 As shown, there are multiple flow channels 13; the multiple flow channels 13 are arranged in a circular array around the length direction of the massage cavity 10.

[0062] The number of multiple flow channels 13 can be two, three, four, five, six, seven, eight, nine, ten or more.

[0063] Multiple flow channels 13 are arranged in a circumferential array around the massage cavity 10 along its length. These flow channels 13 serve as reinforcing ribs for the inner liner 1, and their circumferential array forms a truss-like mechanical support system, significantly improving the inner liner 1's resistance to deformation (especially under water flow impact or external pressure) and extending its service life. The multiple flow channels 13 disperse and discharge the water entering the massage cavity 10, preventing a single flow channel 13 from being unable to promptly drain the liquid from the inner liner 1 when the liquid volume is large, thereby improving the overall cleaning efficiency of the inner liner 1.

[0064] According to some embodiments of this application, optionally, such as Figures 1-3 and Figure 5 As shown, it also includes an outer shell 2, which is fitted onto the outside of the inner liner 1; the outer shell 2 is provided with a second inlet 20 and a second outlet 21; the first inlet 110 is connected to the second inlet 20, and the first outlet 130 is connected to the second outlet 21.

[0065] The hardness of the outer shell 2 can be higher than that of the inner liner 1.

[0066] The outer shell 2 can be detachably connected to the inner liner 1, making it easy to remove the inner liner 1 for cleaning.

[0067] The outer shell 2 can be designed with a curved shape that fits the hand, and can be made with anti-slip texture or soft rubber coating to reduce fatigue during long-term use.

[0068] The outer shell 2 is fitted over the inner liner 1, forming a double-layer structure that effectively resists deformation caused by accidental collisions or drops, protects the internal massage components from external damage, and extends the device's lifespan. The second inlet 20 of the outer shell 2 is connected to the first inlet 110 of the inner liner 1, and the second outlet 21 is connected to the first outlet 130 of the inner liner 1, forming a complete cleaning fluid circulation path. Users can directly inject cleaning fluid through the second inlet 20 of the outer shell 2, allowing it to flow through the flow channel 13 of the inner liner 1 and then be discharged, achieving deep cleaning of the inner liner 1 without the hassle of disassembling it.

[0069] According to some embodiments of this application, optionally, such as Figure 3 As shown, the first inlet 110 of the inner liner 1 extends out of the outer shell 2 through the second inlet 20, and the inner liner 1 is sealed to the inner wall of the second inlet 20.

[0070] The part of the inner shell 1 that extends out of the outer shell 2 can cover the surface of the outer shell 2 facing the user, so that when the user uses the massager provided in this application to massage the massage area, the part of the inner shell 1 that extends out of the outer shell 2 can more easily replace the outer shell 2 to contact the area around the user's massage area. The inner shell 1 is softer than the outer shell 2, which can reduce the pain or discomfort caused by collision or scratching between the area around the user's massage area and the outer shell 2.

[0071] The first inlet 110 of the inner liner 1 extends out of the outer shell 2 through the second inlet 20, forming an independent cleaning interface. Cleaning fluid can enter the inner liner 1 without flowing through the interior of the outer shell 2, reducing the risk of damage to the outer shell 2 due to liquid corrosion. The inner wall of the inner liner 1 is sealed to the inner wall of the second inlet 20, completely isolating the space between the inner liner 1 and the outer shell 2 from the outside. Even if contaminants adhere to the surface of the outer shell 2, they will not enter the space between the inner liner 1 and the outer shell 2 through the second inlet 20, meeting the hygiene standards for medical-grade equipment. The second inlet 20, through its sealed connection with the inner liner 1, can limit the deformation of the portion of the inner liner 1 connected to it, preventing excessive deformation at the first inlet 110 of the inner liner 1 from losing the squeezing and massage effect on the massage area, ensuring a continuous and stable massage effect from the inner liner 1.

[0072] According to some embodiments of this application, optionally, such as Figures 1-2 As shown, the outer shell 2 is provided with a first cover 22; the first cover 22 is used to block the second inlet 20, and the first cover 22 covers the inner liner 1 that extends out of the outer shell 2.

[0073] The first cover 22 can be designed as a sliding or flip-top, allowing users to open it with one hand.

[0074] When the massager is not in use, the first cover 22 blocks the second inlet 20, and the first cover 22 covers the inner liner 1 that protrudes from the outer shell 2, effectively preventing dust, liquid or insects from entering the inner liner 1, which meets the hygiene standards of medical-grade equipment.

[0075] According to some embodiments of this application, optionally, such as Figures 1-3 and Figure 5 As shown, the outer shell 2 is also provided with a second cover 23; the second cover 23 is used to block the second outlet 21; the sealing member 230 is provided on the second cover 23; the second cover 23 is also provided with a limiting groove 231 for fixing the inner liner 1, and the sealing member 230 is located at the center of the limiting groove 231.

[0076] The limiting slot 231 can be interference-fitted with the outer wall surface of part of the inner liner 1 around the flow channel 13, thereby limiting the inner liner 1.

[0077] The second cover 23 can be hinged to the second outlet 21. This reduces the risk of the second cover 23 being lost.

[0078] The surface of the second cover 23 can be provided with a wavy anti-slip texture.

[0079] The sealing element 230 is disposed on the second cover 23, allowing the user to control the opening and closing of the first outlet 130 through the cover without separately disassembling the inner liner 1, thus reducing the preparation time required for cleaning the inner liner 1. The second cover 23 is also provided with a limiting groove 231 for fixing the inner liner 1. The sealing element 230 is located at the center of the limiting groove 231. The limiting groove 231 and the sealing element 230 cooperate to restrict the position of the first outlet 130, thereby allowing the flow channel 13 to remain straight as a whole. This prevents the inner liner 1 from deforming and causing the flow channel 13 to remain bent for a long time, which would make it difficult for the flow channel 13 to return to a straight state on its own, thus hindering the flow of liquid out of the inner liner 1.

[0080] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
