[0007] In some embodiments, the housing is provided with an opening communicating with the inner cavity, and the hose can communicate with the liquid outlet channel through the opening; The second clamping arm mechanism and the opening are arranged sequentially along a second direction, which intersects with the first direction. The second clamping arm mechanism includes a second clamping arm and a second driving structure. The second clamping arm is disposed in the inner cavity.

[0009] In some embodiments, the second clamping arm is provided with a drive rod, and the housing is provided with a guide hole communicating with the inner cavity. The guide hole extends along the second direction. One end of the drive rod is fixedly connected to the second clamping arm, and the other end protrudes from the housing through the guide hole.

[0010] In some embodiments, the skin care product extrusion device further includes a mounting frame extending along the second direction, the mounting frame being fixed in the inner cavity, the mounting frame being provided with a first magnetic suction member extending along the second direction, the second clamping arm being provided with a second magnetic suction member extending along the second direction, and the second magnetic suction member being magnetically connected to the first magnetic suction member.

[0011] In some embodiments, at least one compression protrusion is provided on the side of the second clamping arm body opposite to the rack. When the second clamping arm moves toward the opening, the compression protrusion can move along a second direction parallel to the axial direction of the hose to compress the hose; and / or The mounting bracket, the second clamping arm, and the drive rod are arranged sequentially along a third direction, which is perpendicular to the second direction.

The central axis of the wheel body is parallel to the fourth direction. The plurality of first teeth are distributed circumferentially on the outer peripheral wall of the wheel body. A first through groove is formed between two adjacent first teeth, and the first through groove extends along the fourth direction. The rack is provided with a plurality of spaced second teeth, which are arranged along the second direction. A second through groove is formed between two adjacent second teeth to engage with the first teeth. The second through groove extends along the fourth direction.

When an external force presses the drive handle, the drive handle moves the pawl closer to the ratchet, and the pawl pushes the ratchet to rotate. At this time, the elastic connector undergoes elastic deformation. When the external force is removed, the elastic connector, under its own elasticity, drives the pawl to move the drive handle away from the ratchet, so that the pawl abuts against the groove wall of the next adjacent toothed groove.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] Please see also Figures 1-7In some embodiments, the present invention provides a skin care product extrusion device, including a treatment head 2, a housing 1, a first clamping arm mechanism 3, and a second clamping arm mechanism 4. The treatment head 2 is used to stimulate the skin for skin treatment, and the treatment head 2 has a liquid outlet channel 21 communicating with the outside. The housing 1 is connected to the treatment head 2, and the housing 1 has an inner cavity 11 capable of accommodating a soft tube, and the inner cavity 11 is communicating with the liquid outlet channel 21. The first clamping arm mechanism 3 is disposed in the inner cavity 11. The second clamping arm mechanism 4 is disposed in the inner cavity 11, and the second clamping arm mechanism 4 is spaced apart from the first clamping arm mechanism 3 to form a clamping gap for placing the soft tube. The second clamping arm mechanism 4 can move relative to the first clamping arm mechanism 3 and squeeze the soft tube in the clamping gap to squeeze the skin care product in the soft tube into the liquid outlet channel 21.

[0020] Thus, when the hose is installed in the clamping gap between the second clamping arm mechanism 4 and the first clamping arm mechanism 3, the second clamping arm mechanism 4 can move relative to the first clamping arm mechanism 3 to squeeze the hose located in the clamping gap, so that the skin care product inside the hose can be squeezed into the liquid outlet channel 21. After the skin care product flows out through the liquid outlet channel 21, it comes into contact with the skin to care for the skin. At the same time, the physiotherapy head 2 can provide physiotherapy to the skin and promote the absorption of the skin care product. The hose can be housed in the inner cavity 11 of the housing 1. The housing 1 can protect the hose, making it less likely to be squeezed by external objects, and reducing the risk of accidental liquid discharge or accidental damage to the hose.

[0021] In this embodiment, the therapy head 2 can be detachably connected to the hose. The detachable connection between the outer shell and the hose can be achieved by threaded connection, snap-fit ​​connection, magnetic connection, etc. The therapy head 2 is provided with a therapy surface 222, and the liquid outlet channel 21 is connected to the therapy surface 222. When the therapy surface 222 is close to or in contact with the skin, it can provide therapy to the skin. The therapy methods include, but are not limited to, phototherapy, microcurrent, vibration, hot compress, cold compress, roller massage, etc.

[0022] In one specific embodiment, reference is made to Figure 7 The therapy head 2 includes a housing 22 and a therapy component 23. The therapy component 23 is disposed on the housing 22, and the therapy surface 222 is disposed on the housing 22. The therapy component 23 can be fixed inside the housing 22 or fixed to the outer wall of the housing 22, which is not limited here. The therapy component 23 includes a first circuit board 231 electrically connected to the skin and a stimulating element 232. The stimulating element 232 is used to stimulate the skin to perform therapy. The housing 22 has a mounting bracket 221 inside, and a first liquid outlet channel 2211 is provided on the mounting bracket 221. The housing 22 has a second liquid outlet channel 24. The first liquid outlet channel 2211 and the second liquid outlet channel 24 are sealed together to form a liquid outlet channel 21, so that the skin care product squeezed out of the tube can flow out of the therapy head 2 and come into contact with the skin, so as to facilitate skin care and therapy.

[0023] In one embodiment, the physiotherapy head 2 further includes a sealing element 25, one end of which is sealed to the first liquid outlet pipe 2211 and the other end of which is sealed to the second liquid outlet pipe 24, thereby achieving a sealed connection between the first liquid outlet pipe 2211 and the second liquid outlet pipe 24 and reducing leakage.

[0024] In this embodiment, the stimulation element 232 includes at least one of a phototherapy lamp, a conductive electrode, a semiconductor cooling element, a heating element, and a vibration motor, which is not limited thereto.

[0025] See Figure 6 In some embodiments, the first clamping arm mechanism 3 and the second clamping arm mechanism 4 are along a first direction (e.g., Figure 6 The first clamping arm mechanism 3 includes a first clamping arm 31 and a first driving structure 32, which are spaced apart in the X direction. The first clamping arm 31 is disposed in the inner cavity 11. The first driving structure 32 is connected to the first clamping arm 31 and can drive the first clamping arm 31 to move relative to the housing 1 in the first direction to adjust the width of the clamping gap in the first direction.

[0026] Thus, the first clamping arm 31 is moved by the first driving structure 32, which changes the distance between the first clamping arm mechanism 3 and the second clamping arm mechanism 4, thereby adjusting the width of the clamping gap along the first direction. This allows the hose to be clamped or released, facilitating hose assembly and disassembly. At the same time, the width of the clamping gap can be flexibly adjusted according to the size of the hose, enabling the first clamping arm mechanism 3 and the second clamping arm mechanism 4 to clamp hoses of various sizes, thus improving the practicality of the skin care extrusion equipment.

[0027] The first clamping arm 31 can be a plate-like structure extending along the second direction, or an arc-shaped structure protruding toward the second clamping arm mechanism, or an arc-shaped string structure formed by connecting multiple arc-shaped structures, and is not limited here.

[0028] See Figures 1-6 In some embodiments, the housing 1 is provided with a through hole, and the first drive structure 32 includes a rotating handle 321, a nut 322 and a screw 323 extending along a first direction. The nut 322 is disposed in the inner cavity 11 and connected to the first clamping arm 31. The nut 322 is engaged with the outer periphery of the screw 323. The rotating handle 321 protrudes from the housing 1. One end of the screw 323 is helically connected to the nut 322, and the other end is fixedly connected to the rotating handle 321 after passing through the through hole.

[0029] Thus, the user can rotate the rotating handle 321 outside the housing 1, which drives the screw 323 to rotate, so that the nut 322 can drive the first clamping arm 31 to move relative to the screw 323 in the first direction, thereby adjusting the clamping gap between the first clamping arm mechanism 3 and the second clamping arm mechanism 4 to clamp or release the hose.

[0030] In some other embodiments, the first drive structure 32 may also be an electric push rod, a cylinder, or a hydraulic cylinder, etc., and is not limited here. For example, in an embodiment not shown, the first drive structure 32 is a linear motor fixed to the inner wall of the housing 1. The output shaft of the linear motor is fixedly connected to the first clamping arm 31. The linear motor can drive the first clamping arm 31 to move along a first direction to adjust the width of the clamping gap between the first clamping arm mechanism 3 and the second clamping arm mechanism 4.

[0031] See Figures 1-6 In some embodiments, the housing 1 is provided with an opening 12 communicating with the inner cavity 11, and the hose can communicate with the liquid outlet channel 21 through the opening 12. The second clamping arm mechanism 4 and the opening 12 are along a second direction (e.g., Figure 6 The second clamping arm mechanism 4 includes a second clamping arm 41 and a second driving structure 42. The second clamping arm 41 is disposed in the inner cavity 11. The second driving structure 42 is connected to the second clamping arm 41 and can drive the second clamping arm 41 to move relative to the opening 12 along the second direction.

[0032] Thus, the second clamping arm 41 is driven by the second drive structure 42 to move relative to the opening 12 in the second direction, so as to squeeze the skin care product in the tube toward the opening 12, so that the skin care product can enter the liquid outlet channel 21, and then flow out through the liquid outlet channel 21 to contact the skin and care for the skin.

[0033] The angle between the second direction and the first direction can be 30°, 45°, 60°, 75°, 90°, etc., and is not limited here.

[0034] See Figure 6In some embodiments, the second drive structure 42 includes a ratchet 421 and a gear transmission component 422. The ratchet 421 and the gear transmission component 422 are drivenly connected. For example, the ratchet 421 and the gear transmission component 422 can be coaxially fixedly connected by a connecting rod, or the ratchet 421 and the gear transmission component 422 are an integral structure, or the ratchet 421 and the gear transmission component 422 are fixedly connected by bolts. The second clamping arm 41 includes a second clamping arm body 411 and a rack 412 connected to each other along the first direction. The second clamping arm body 411 and the rack 412 can be an integral structure or a separate structure. The split structure is connected by means of screws, adhesives, welding, etc., which is not limited here; the rack 412 extends along the second direction, and the second clamping arm body 411 is located on the side of the rack 412 near the first clamping arm mechanism 3. The second clamping arm body 411 and the first clamping arm mechanism 3 are spaced apart to form a clamping gap. The gear transmission component 422 is meshed with the rack 412. When the ratchet 421 rotates, it can drive the gear transmission component 422 to rotate synchronously, so that the gear transmission component 422 can drive the second clamping arm body 411 to move towards the opening 12 and squeeze the hose.

[0035] Thus, when the ratchet 421 rotates, it can drive the gear transmission component 422 to rotate synchronously, so that the gear transmission component 422 can drive the second clamping arm body 411 to move closer to the opening 12 and squeeze the tubing, so as to squeeze the skin care product in the tubing into the liquid outlet channel 21, and then flow out through the liquid outlet channel 21 to contact the skin and care for the skin.

[0036] In some other embodiments, the second drive structure 42 may also be a ball screw, an electric actuator, a timing belt structure, etc., which are not limited here.

[0037] See Figures 1-6 In some embodiments, the second clamping arm 41 is provided with a drive rod 413, and the housing 1 is provided with a guide hole 14 communicating with the inner cavity 11. The guide hole 14 extends along the second direction. One end of the drive rod 413 is fixedly connected to the second clamping arm 41, and the other end protrudes out of the housing 1 through the guide hole 14. The guide hole 14 is used to guide the drive rod 413 to move along the second direction.

[0038] Thus, the guide hole 14 can guide the drive rod 413 to move in the second direction, thereby providing a guiding effect on the second clamping arm 41 in the second direction. When the second clamping arm 41 moves in the second direction toward the opening 12 under the meshing transmission of the gear transmission member 422, the drive rod 413 moves along the guide hole 14 to guide the movement direction of the second clamping arm 41, making it less likely for the second clamping arm 41 to deviate during the movement, and making it less likely for the meshing connection between the rack 412 and the gear transmission member 422 to come loose accidentally.

[0039] See Figures 1-6 In some embodiments, the skin care product extrusion device further includes a mounting frame 15 extending along a second direction. The mounting frame 15 is fixed in the inner cavity 11. The mounting frame 15 is provided with a first magnetic suction member 151 extending along the second direction. The second clamping arm 41 is provided with a second magnetic suction member 414 extending along the second direction. The second magnetic suction member 414 is magnetically connected to the first magnetic suction member 151.

[0040] Thus, when the second clamping arm 41 moves along the second direction, the second magnetic suction member 414 can move along the first magnetic suction member 151, providing a guiding function for the second clamping arm 41. When the second clamping arm 41 moves along the second direction toward the opening 12, the second magnetic suction member 414 and the first magnetic suction member 151 are magnetically attracted and limited, making it less likely for the second clamping arm 41 to deviate accidentally. In addition, the second clamping arm 41 is detachably connected to the mounting bracket 15 by magnetic attraction, making it easy to pull the second clamping arm 41 off the mounting bracket 15 and then manually adjust the position of the second clamping arm 41 on the mounting bracket 15.

[0041] The first magnetic attractor 151 and the second magnetic attractor 414 can both be magnets; or the first magnetic attractor 151 can be a magnet and the second magnetic attractor 414 can be a ferromagnetic component that attracts the magnet; or the second magnetic attractor 414 can be a magnet and the first magnetic attractor 151 can be a ferromagnetic component that attracts the magnet, and no limitation is made here. The first magnetic attractor 151 and the second magnetic attractor 414 can be a strip structure, a box-shaped structure or a cylindrical structure, and no limitation is made here; the mounting bracket 15 can be an independent component installed in the inner cavity 11 of the housing 1, or it can be an integral structure formed with the housing 1.

[0042] In an optional embodiment, the height of the first magnetic member 151 in the second direction is greater than the sum of the height of the second magnetic member 414 in the second direction and the displacement of the second clamping arm 41 in the second direction, so that when the second clamping arm 41 moves in the second direction, the second magnetic member 414 can always be magnetically connected to the first magnetic member 151, reducing the risk of the second clamping arm 41 derailing.

[0043] See Figure 6 In some embodiments, at least one extrusion protrusion 415 is provided on the side of the second clamping arm body 411 opposite to the rack 412. When the second clamping arm 41 moves toward the opening 12, the extrusion protrusion 415 can move the extrusion hose in a second direction parallel to the axial direction of the hose.

[0044] Thus, when the second clamping arm 41 moves toward the opening 12, the squeezing protrusion 415 can move in the second direction to squeeze the tube and squeeze out the skin care product in the tube.

[0045] The number of extrusion protrusions 415 can be one, two, three, four, etc. When there are multiple extrusion protrusions 415, they are evenly arranged on the second clamping arm body 411 along the second direction. When the second clamping arm 41 moves towards the opening 12, the multiple extrusion protrusions 415 can sequentially extrude the same section of the tube, so that most of the skin care products in the tube can be extruded, reducing the waste of skin care products.

[0046] See Figure 3 In some embodiments, the mounting bracket 15, the second clamping arm 41, and the drive rod 413 are along a third direction (e.g., Figure 6 The two magnetic components are arranged sequentially in the Z direction, with the third direction perpendicular to the second direction. The second clamping arm 41 is provided with a guide groove 416 that mates with the first magnetic component 151. The second magnetic component 414 is fixed in the guide groove 416.

[0047] Thus, the mounting bracket 15, the second clamping arm 41, and the drive rod 413 are arranged sequentially along the third direction. The second clamping arm 41 is magnetically connected to the second magnetic member 414 on the mounting bracket 15 via the first magnetic member 151. The mounting bracket 15 acts as a stop for the second clamping arm 41, preventing the second clamping arm 41 from moving towards the mounting bracket 15 along the third direction. By driving the drive rod 413, the second clamping arm 41 can only be moved away from the mounting bracket 15 along the third direction, allowing the second magnetic member 414 to separate from the first magnetic member 151, so that the second clamping arm 41 can be reset after leaving the mounting bracket 15.

[0048] See Figure 6 In some embodiments, ratchet 421 is a one-way ratchet, and drive lever 413 is driven in a fourth direction (e.g., Figure 6 The gear transmission component 422 (located in the Z direction) is movably disposed in the inner cavity 11. It includes a gear body 4221 and multiple first teeth 4222. The central axis of the gear body 4221 is parallel to the fourth direction. The multiple first teeth 4222 are distributed circumferentially on the outer peripheral wall of the gear body 4221. A first through groove 4223 is formed between adjacent first teeth 4222, extending along the fourth direction. The rack 412 is provided with multiple spaced-apart teeth. The second tooth 4121 is arranged in a second direction. A second through groove 4122 is formed between two adjacent second teeth 4121 to engage with the first tooth 4222. The second through groove 4122 extends in a fourth direction. The first tooth 4222 is detachably inserted into the second through groove 4122 in the fourth direction. The second tooth 4121 is detachably inserted into the first through groove 4223 in the fourth direction. The fourth direction is perpendicular to the second direction.

[0049] Thus, ratchet 421 is a one-way ratchet, which can only rotate in one direction. This means that the second drive structure can only drive the second clamping arm 41 to move towards the opening 12 in the second direction, and cannot drive the second clamping arm 41 to move away from the opening 12 in the second direction. This reduces the risk of negative pressure being generated in the tube when the second clamping arm 41 moves away from the opening 12 in the second direction, reducing the problem of squeezed skin care products being sucked back into the tube due to negative pressure. It also prevents air from entering the tube due to the sucking action, reducing the problem of skin care products deteriorating due to contact with air. If the second clamping arm 41 moves to its maximum stroke towards the opening 12 under the drive of the second drive structure, the second clamping arm 41 can no longer squeeze the tube. At this time, the second clamping arm 41 needs to be manually moved back to the end away from the opening 12 by the drive rod 413 so that the second clamping arm 41 can move towards the opening 12 again and squeeze the tube. The driving principle of the drive rod 413 is as follows: When the drive rod 413 is pulled out of the housing 1 along the fourth direction, the second tooth 4121 can disengage from the gear transmission member 422 along the first through groove 4223, so that the drive rod 413 can move to the initial position along the second direction away from the opening 12, so that the second clamping arm 41 can fall back to the end of the inner cavity 11 away from the opening 12, which is convenient for clamping and squeezing the new hose.

[0050] See Figure 6 In some embodiments, the ratchet 421 has multiple toothed grooves evenly distributed along the circumference of the ratchet 421. The second drive structure 42 also includes a drive handle 423, a pawl 424, and an elastic connector 425. One end of the pawl 424 is rotatably connected to the drive handle 423, and the other end abuts against the groove wall of one toothed groove of the ratchet 421. The drive handle 423 protrudes from the housing 1. One end of the elastic connector 425 is connected to the pawl 424, and the other end is connected to the housing 1. When an external force presses the drive handle 423, the drive handle 423 drives the pawl 424 to move closer to the ratchet 421, and the pawl 424 pushes the ratchet 421 to rotate. At this time, the elastic connector 425 undergoes elastic deformation. When the external force is removed, the elastic connector 425, under its own elasticity, drives the pawl 424 to move the drive handle 423 away from the ratchet 421, so that the pawl 424 abuts against the groove wall of the next adjacent toothed groove.

[0051] Ratchet 421 is typically a gear with specially shaped teeth. A tooth groove is formed between adjacent teeth. One wall of the groove is usually a steep stop surface, while the other wall is a gentler guide surface. The stop surface and guide surface are connected at an angle. Under the elastic force of the elastic connector 425, the tip of the pawl 424 is pressed tightly against the groove wall. Each press of the drive handle 423 causes the pawl 424 to push the steep stop surface in the direction that allows the ratchet 421 to rotate (i.e., the first driving direction). The pawl 424 can directly transmit force to the ratchet 421, thereby driving the ratchet 421. 1. The gear transmission component 422 can be driven to rotate synchronously at a preset angle, so that the second clamping arm 41 can move a preset distance along the second direction towards the opening 12, so that each press of the drive handle 423 can squeeze out a certain amount of skin care product from the tube. The operation is simple and convenient for users. After each squeeze, the rack 412 can maintain the squeezing state of the tube, so that the tube will not return to its original state after each squeeze. The next time you squeeze, you only need to drive the rack 412 to continue to move towards the opening 12 to continue squeezing the tube. This can reduce the squeezing difficulty and squeeze the skin care product out of the tube more quickly. After the pressure applied to the drive handle 423 is released, the elastic connector 425 returns to its elastic deformation. The elastic connector 425 drives the pawl 424 to move in the second drive direction opposite to the first drive direction. When the pawl 424 moves, it can move along the relatively flat guide surface and slide into the next tooth groove. Under the action of the elastic force of the elastic connector 425, the tip of the pawl 424 is pressed again against the groove wall of the tooth groove and abuts against the stop surface. The pawl 424 can block the stop surface and prevent the ratchet 421 from moving in the opposite direction. The ratchet 421 can lock the current position and prevent the second clamping arm 41 from moving backward under the action of the tube elasticity or internal pressure. This ensures that the skin care product in the tube is always in the "ready to be extruded" state, and the extrusion response is faster in the next operation.

[0052] The elastic connector 425 can be a spring or tension spring, etc., which can be used to drive the drive handle 423 to reset, so as to facilitate the next drive of the second drive structure 42.

[0053] In some optional embodiments, the second drive structure 42 further includes a check pawl and a tension spring. The check pawl abuts against the tooth groove of the ratchet 421. One end of the check pawl is rotatably connected to the cavity wall of the inner cavity 11 via a rotating shaft. One end of the tension spring is connected to the other end of the check pawl, and the other end of the tension spring is connected to the cavity wall of the inner cavity 11. Under the action of the tension spring, when no external force is applied, the check pawl can always abut against the tooth groove of the ratchet 421 to prevent the ratchet 421 from rotating unexpectedly.

[0054] See Figures 1-6In some embodiments, the present invention also provides a physiotherapy device, including a tubing and a skin care product extrusion device as described above, the tubing being disposed in a clamping gap.

[0055] In some embodiments, the inner cavity 11 has a bottom wall opposite to the opening 12, and a positioning groove extending in a third direction is provided on the bottom wall. The tail end of the hose can be engaged in the positioning groove to assist the hose in quick positioning and to facilitate fixing the hose into the clamping gap of the inner cavity 11; or an elastic claw is provided on the bottom wall of the inner cavity 11, and the elastic claw is correspondingly provided with the clamping gap. The tail end of the hose can be clamped on the elastic claw to assist the hose in quick positioning and to facilitate fixing the hose into the clamping gap of the inner cavity 11.

[0056] See Figures 1-6 In some embodiments, the housing 1 includes a housing body and a cover 16. The housing body is provided with a first notch 13. One end of the cover 16 is rotatably disposed on the housing body, and the other end is provided with a second notch 161. When the cover 16 is closed on the housing body, the first notch 13 and the second notch 161 surround and form an opening 12. When the hose is installed in the inner cavity 11, the hose opening can extend out from the opening 12 to facilitate connection with the physiotherapy head 2.

[0057] The connection between the cover 16 and the housing body can be achieved through a pivot connection, hinge connection, snap-fit ​​connection, magnetic connection, etc. Preferably, the cover 16 and the housing body are rotatably connected via a pivot connection, hinge connection, or other rotatable connection method. This allows the cover 16 to be opened or closed without complete disassembly, simply by rotating it. This reduces the likelihood of the cover 16 being lost, lowers the difficulty of disassembling and assembling the cover 16, and reduces the risk of misinstallation. Furthermore, flipping the cover 16 removes the obstruction of the opening 12, resulting in a larger opening area and providing the user with more operating space for installing and removing the hose.

[0058] In some embodiments, the second notch 161 has an elastic protrusion 162 arranged in the circumferential direction of the opening 12 on its wall. When the hose is installed on the housing 1, the elastic protrusion 162 abuts against the outer wall of the hose. During installation, the hose is first installed into the inner cavity 11, at which time the hose end protrudes from the first notch 13. Then, the cover 16 is placed on the housing 1 so that the elastic protrusion 162 can abut against the outer wall of the hose to fix the hose.
