Detailed Implementation

[0041] The following description provides specific application scenarios and requirements for this disclosure, intended to enable those skilled in the art to make and use the content of this disclosure. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this disclosure. Therefore, this disclosure is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0042] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” as used herein may also include the plural forms. When used in this disclosure, the terms “comprising,” “including,” and / or “containing” mean that the associated feature, integer, step, operation, element, and / or component is present, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or the possibility of adding other features, integers, steps, operations, elements, components, and / or groups to the system / method.

[0043] In view of the following description, these and other features of this disclosure, as well as the operation and function of the related elements of the structure, and the economy of assembly and manufacture of the components, can be significantly improved. All of these form part of this disclosure with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this disclosure. It should also be understood that the drawings are not drawn to scale.

[0044] The flowcharts used in this disclosure illustrate operations implemented according to some embodiments of this disclosure. It should be clearly understood that the operations in the flowcharts may not be implemented sequentially. Instead, the operations may be implemented in reverse order or simultaneously.

And so on.

[0047] Skin tags can be removed from the skin through cryotherapy. Existing technologies include cryotherapy devices for removing skin tags. However, these devices are relatively complex to operate and not convenient for users to manually remove their own skin tags.

[0048] In view of this, such as Figure 1 , Figure 2 and Figure 5 As shown, this disclosure provides a liquid release device 001. The liquid release device 001 includes a handheld body 100 and a trigger 200. The handheld body 100 includes a housing 120, a reservoir 110, and a nozzle 130. The housing 120 includes a receiving cavity 123. The reservoir 110 is located within the receiving cavity 123 and includes a liquid outlet 1111, which allows liquid within the reservoir 110 to be discharged through the liquid outlet 1111 when opened. The nozzle 130 is located at a first end 101 of the handheld body 100, connected to the housing 120, and communicating with the liquid outlet 1111. It is configured to receive and position a buffer 300 such that the buffer 300 is opposite the liquid outlet 1111. A trigger 200 is disposed at the second end 102 of the handheld body 100, movably connected to the housing 120, and drivenly connected to the liquid reservoir 110. It is configured to move the liquid reservoir 110 and open the liquid outlet 1111 to release liquid through the outlet 1111. The user can hold the handheld body 100 with one hand and operate the trigger 200, thus enabling the user to release cryogenic liquid with one hand, facilitating the use of the liquid release device 001. The user can release the cryogenic liquid onto the skin where skin tags are present, thereby removing the skin tags.

[0049] The cryogenic liquid released by the liquid release device 001 provided in this disclosure can be liquid nitrogen, other cryogenic liquids that promote the removal of skin tags, or mixtures of other cryogenic liquids and liquid nitrogen. Of course, the liquid release device 001 can also release liquids unrelated to liquid nitrogen. For example, the liquid release device 001 can release liquids with whitening or cosmetic effects. This disclosure does not limit this.

[0050] The structure of the liquid release device 001 is described in detail below.

[0051] Figure 1 A schematic diagram of a liquid release device according to some embodiments of the present disclosure is shown. The liquid release device 001 includes a trigger 200, a handheld body 100, and a buffer 300. The buffer 300 is positioned at a predetermined position outside the handheld body 100. The handheld body 100 extends along a first direction D1. For example, the handheld body 100 may be approximately cylindrical. The handheld body 100 has a first end 101 and a second end 102. The trigger 200 is disposed at the second end 102 of the handheld body 100 and is used to control the liquid release device 001 to release liquid to the buffer 300, and then the liquid can be released to the outside through the buffer 300. The buffer 300 is located at the first end 101 of the handheld body 100 and can be used to align with and contact human skin. When using the liquid release device 001, the user can use fingers other than the thumb to hold the portion of the handheld body 100 between the first end 101 and the second end 102 to control the orientation and spatial position of the buffer 300. At the same time, the user can use the thumb to operate the trigger 200. This allows the user to operate the liquid release device 001 with one hand, making it easier for the user to use the liquid release device 001.

[0052] In some embodiments, such as Figure 1 As shown, the maximum radial dimension L1 of the handheld body 100 is 10mm to 60mm. The radial direction of the handheld body 100 is perpendicular to the first direction D1. For example, the maximum radial dimension L1 of the handheld body 100 can be 10mm to 15mm, 15mm to 20mm, 20mm to 25mm, 25mm to 30mm, 30mm to 40mm, 40mm to 50mm, or 50mm to 60mm. This facilitates one-handed gripping of the handheld body 100, thereby facilitating the use of the liquid release device 001. When the outer periphery of the handheld body 100 is irregular, the maximum radial dimension L1 can be calculated using the following formula: C1 = π × L1, where C1 is the maximum circumference of the outer periphery of the handheld body 100 perpendicular to the first direction D1.

[0053] Figure 2 A cross-sectional structural schematic diagram of a liquid release device provided according to some embodiments of the present disclosure is shown. Figure 3 A schematic diagram of the housing of a liquid release device according to some embodiments of the present disclosure is shown. Figure 2 and Figure 3As shown, the handheld body 100 may include a liquid reservoir 110 and a housing 120. The housing 120 forms the sidewall of the handheld body 100. The liquid reservoir 110 is capable of storing and releasing liquid. A receiving cavity 123 is formed inside the housing 120, and a mounting port 124 is formed at the second end 102 of the housing 120, with the liquid reservoir 110 located within the receiving cavity 123. The mounting port 124 communicates with the receiving cavity 123. Further, the mounting port 124 communicates with the receiving cavity 123 along a first direction D1. When assembling the liquid reservoir 110 and the housing 120, the liquid reservoir 110 can be installed into the receiving cavity 123 along the first direction D1 through the mounting port 124.

[0054] In some embodiments, such as Figure 3 As shown, the inner wall of the outer casing 120 is provided with multiple limiting ribs 125 extending along the first direction D1, and the multiple limiting ribs 125 surround the liquid reservoir 110. The liquid reservoir 110 may include a tank body 112, a liquid outlet pipe 111, and a seal 113. Specifically, the multiple limiting ribs 125 surround the tank body 112. The multiple limiting ribs 125 can position the liquid reservoir 110 along the radial direction of the handheld body 100. This facilitates the stable assembly of the liquid reservoir 110 within the outer casing 120. In addition, the limiting ribs 125 can also strengthen the outer casing 120. For example, four limiting ribs 125 extending along the first direction are arranged around the inner wall of the outer casing 120, the distance between two adjacent limiting ribs 125 is equal, and the four limiting ribs 125 are arranged opposite each other in pairs.

[0055] Furthermore, such as Figure 2 and Figure 3 As shown, at the second end 102 of the handheld body 100, the distance between the ends of the two opposing limiting ribs 125 is less than the maximum outer diameter of the trigger member 200. Therefore, when the trigger member 200 moves relative to the outer shell 120 along the first direction D1, the end of the limiting rib 125 near the second end 102 can abut against the side of the trigger member 200 near the first end 101, thus restricting the trigger member 200 from continuing to move relative to the handheld body 100 along the first direction D1. By limiting the trigger member 200 with the limiting ribs 125, the maximum travel distance of the trigger member 200 relative to the outer shell 120 along the first direction D1 can be limited, which also limits the maximum travel distance of the trigger member 200.

[0056] The determination of the maximum moving distance of the trigger 200 along the first direction D1, that is, the determination of the maximum moving distance of the reservoir 110 along the first direction D1, is also the determination of the maximum single liquid output of the reservoir 110.

[0057] Specifically, driven by the trigger 200, the tank 112 of the reservoir 110 moves relative to the outer casing 120 along the first direction D1. Simultaneously, the end of the outlet pipe 111 of the reservoir 110 away from the second end 102 abuts against the limiting part 121, thereby discharging the cryogenic liquid from the outlet 111. Once the maximum moving distance of the trigger 200 is determined, the maximum moving distance of the tank 112 relative to the outlet 111 is also determined, thus determining the maximum single-time discharge volume of the outlet 111, which in turn determines the maximum single-time discharge volume of the reservoir 110. By limiting the maximum single-time discharge volume of the reservoir 110, excessive force applied by the user when using the liquid release device 001 to the trigger 200 can be avoided, preventing excessive release and waste of cryogenic liquid from the reservoir 110. This improves the utilization rate of the cryogenic liquid.

[0058] Furthermore, the limiting rib 125 may include a first rib segment 1251 and a second rib segment 1252. The first rib segment 1251 has a gap with the can body 112. The second rib segment 1252 abuts against the can body 112 or has a small gap with the can body 112 to position the can body 112 radially along the handle body 100. The distance between the first rib segment 1251 and the mounting port 124 is less than the distance between the second rib segment 1252 and the mounting port 124. When assembling the can body 112 into the outer casing 120, the can body 112 first passes through the first rib segment 1251 and then through the second rib segment 1252. Thus, the first rib segment 1251 can act as a guide to facilitate the assembly of the can body 112 between the multiple second rib segments 1252.

[0059] Figure 4 A schematic diagram of the assembly structure of the trigger and the reservoir of a liquid release device according to some embodiments of the present disclosure is shown. Figure 2 and Figure 4 As shown, the trigger 200 is movably connected to the housing 120 and driven by the valve of the reservoir 110 to control the release of liquid from the reservoir 110. By moving relative to the housing 120, the trigger 200 can actuate the valve to open, thereby releasing liquid through the outlet 1111 of the reservoir 110.

[0060] In some embodiments, the trigger 200 is movably disposed at the second end 102 of the handheld body 100 along a first direction D1. The trigger 200 can actuate the valve by moving relative to the handheld body 100 along the first direction D1. This facilitates manual control of the movement of the trigger 200 relative to the handheld body 100 by the user. In other embodiments, the trigger 200 is configured to move radially along the handheld body 100.

[0061] The following provides a detailed description of several implementation methods of the trigger 200 and the reservoir 110.

[0062] (a) such as Figure 2 and Figure 4 As shown, the liquid reservoir 110 includes a tank body 112, a liquid outlet pipe 111, a seal 113, and an elastic member 114. The tank body 112 is used to store liquid. The tank body 112 is movably connected to the liquid outlet pipe 111 along a first direction D1. The liquid outlet pipe 111 extends from inside the tank body 112 to the outside of the tank body 112. The portion of the liquid outlet pipe 111 inside the tank body 112 includes a liquid inlet 1112. The end of the liquid outlet pipe 111 away from the tank body 112 includes a liquid outlet 1111, i.e., the liquid outlet 1111 is located outside the tank body 112. The seal 113 and the elastic member 114 are both located inside the tank body 112. A support portion 115 is fixedly disposed inside the tank body 112, and the elastic member 114 abuts against the support portion 115. The elastic member 114 also abuts against the end of the liquid outlet pipe 111 located inside the tank body 112.

[0063] like Figure 2 and Figure 4 As shown, the outlet pipe 111 can form a valve. When the elastic element 114 is not elastically deformed, the sealing element 113 blocks the inlet 1112, and the valve is closed. When the outlet pipe 111 moves relative to the tank 112, the inlet 1112 is offset from the sealing element 113, causing the valve to open and the elastic element 114 to elastically deform. When the valve is open, the inlet 1112 is connected to the inside of the tank 112. Since the pressure inside the tank 112 is higher than the external atmospheric pressure, the liquid inside the tank 112 can enter the outlet pipe 111 through the inlet 1112 and then be released to the outside through the outlet 1111. Therefore, when the valve is open, it allows the liquid in the reservoir 110 to be discharged through the outlet 1111. When the elastic element 114 recovers its elastic deformation, the outlet pipe 111 can be reset relative to the tank 112.

[0064] In some embodiments, such as Figure 2 and Figure 4 As shown, the liquid outlet pipe 111 abuts against the limiting portion 121 of the handheld body 100 along the first direction D1. Further, the limiting portion 121 may be located at the end of the housing 120 away from the mounting port 124 and opposite to the mounting port 124. The limiting portion 121 can position the liquid outlet pipe 111 to ensure that the cryogenic liquid discharged from the liquid outlet pipe 111 can be discharged through the drainage channel and smoothly reach the buffer member 300 located on the side of the limiting portion 121 opposite to the trigger member 200.

[0065] For example, such as Figure 2 and Figure 3As shown, the drain channel 122 is a stepped hole extending along the first direction D1. The drain channel 122 has a first section 1221 and a second section 1222. The diameter of the first section 1221 is larger than the diameter of the second section 1222. Thus, a stepped surface 1223 is formed at the junction of the first section 1221 and the second section 1222. The outer periphery of the end of the outlet 1111 away from the trigger 200 abuts against the stepped surface 1223 along the first direction D1. That is, the end of the outlet pipe 111 away from the tank body 112 can be located within the first section 1221 and abut against the stepped surface 1223 along the first direction D1. The diameter of the first section 1221 is adapted to the diameter of the outlet pipe 111. In this way, the limiting part 121 can position the outlet pipe 111 through the drain channel 122. The outlet 1111 is opposite to the buffer 300 through the opening of the drain channel 122. Liquid released from outlet 1111 can be released into buffer 300 through second orifice 1222.

[0066] like Figure 2 and Figure 3 As shown, the trigger 200 abuts against the tank body 112 along the first direction D1. This allows the trigger 200 and the limiting part 121 to clamp the reservoir 110 along the first direction D1. This facilitates the stable assembly of the reservoir 110 within the outer casing 120. When the trigger 200 is activated, it causes the tank body 112 to move relative to the outlet pipe 111 along the first direction D1, thereby opening the valve.

[0067] Furthermore, such as Figure 2 and Figure 4 As shown, the handheld body 100 includes an elastic gasket 140. The elastic gasket 140 is located between the trigger 200 and the tank 112, and the elastic gasket 140 can elastically deform along a first direction D1. The trigger 200 elastically abuts against the tank 112 through the elastic gasket 140. The elastic gasket 140 helps to increase the connection and transmission effect between the trigger 200 and the tank 112. This can reduce the risk of the reservoir 110 shaking relative to the outer casing 120, and can also overcome the fit tolerance between the trigger 200 and the tank 112 to improve the transmission reliability between the trigger 200 and the tank 112.

[0068] In some embodiments, such as Figure 2 and Figure 3As shown, the mounting port 124 is located at the second end 102 of the handheld body 100. The mounting port 124 can be square, circular, or other shapes. The trigger 200 can be adapted to the dimensions of the mounting port 124 and the receiving cavity 123, and seal the mounting port 124. In this way, the trigger 200 can confine the reservoir 110 within the receiving cavity 123. The mounting port 124 and the receiving cavity 123 provide space for the trigger 200 to move along the first direction D1. In addition, the inner wall of the receiving cavity 123 can guide the movement of the trigger 200 along the first direction D1.

[0069] Figure 5 An exploded view of a liquid release device provided according to some embodiments of the present disclosure is shown. Figure 6 Another exploded view of a liquid release device provided according to some embodiments of the present disclosure is shown. In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the trigger 200 has a second cantilever 214 and an elastic latching portion 210 connected to the end of the second cantilever 214. The housing 120 has a limiting groove 126, and the elastic latching portion 210 is movably located within the limiting groove 126 along a first direction D1 or a third direction D3. The limiting groove 126 provides movement space for the elastic latching portion 210, so that the elastic latching portion 210 can move along the first direction D1. In other embodiments, the trigger 200 has a limiting groove 126, and the housing 120 has an elastic latching portion 210, which is movably located within the limiting groove 126 along the first direction D1 or a third direction D3.

[0070] In some embodiments, the trigger 200 includes two second cantilever arms 214, which are disposed opposite to each other on both sides of the trigger 200. Each second cantilever arm 214 is provided with an elastic latching portion 210. The housing 120 includes two limiting grooves 126 corresponding to the two elastic latching portions 210, and the elastic latching portions 210 and the limiting grooves 126 correspond one-to-one.

[0071] The trigger 200 and the housing 120 are detachably connected via the engagement of the elastic latch 210 and the limiting groove 126. Furthermore, the elastic latch 210 can be inserted into the limiting groove 126 radially along the handheld body 100. That is, when the elastic latch 210 is located within the limiting groove 126, the limiting groove 126 restricts the elastic latch 210 from moving away from the housing 120 in the third direction D3. Simultaneously, the inner wall of the receiving cavity 123 restricts the radial movement of the trigger 200 along the handheld body 100. This enables the connection between the trigger 200 and the housing 120.

[0072] The elastic latch 210 can move radially away from the limiting groove 126 along the handheld body 100 through elastic deformation, and then the trigger 200 can move away from the receiving cavity 123 to the outside along the third direction D3. This enables the trigger 200 to be removed from the outer shell 120. Specifically, the elastic latch 210 connected to the second cantilever 214 is pressed by the limiting groove 126, and the second cantilever 214 deforms under force, causing the elastic latch 210 to move towards the receiving cavity 123 until the elastic latch 210 is allowed to slide from the limiting groove 126 into the inner wall of the receiving cavity 123. Furthermore, under the pull of external force, the elastic latch 210 can be disengaged from the outer shell 120 along the third direction D3, that is, the trigger 200 disengages from the outer shell 120 along the third direction D3.

[0073] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the limiting groove 126 includes a first sliding groove 1261 and a second sliding groove 1262. The first sliding groove 1261 extends along a first direction D1. The second sliding groove 1262 extends along a second direction D2 and communicates with the first sliding groove 1261. The second direction D2 is perpendicular to the first direction D1. For example, the second direction D2 is the circumferential direction of the handheld body 100. The position of the elastic latch 210 can be switched within the first sliding groove 1261 and the second sliding groove 1262.

[0074] Along the second direction D2, the size of the first slide groove 1261 is greater than or equal to the size of the elastic latching portion 210, allowing the elastic latching portion 210 to move along the first slide groove 1261. When the elastic latching portion 210 is located within the first slide groove 1261, the first slide groove 1261 allows the elastic latching portion 210 to move along the first direction D1. Further, along the second direction D2, the size of the first slide groove 1261 is adapted to the elastic latching portion 210, so that the first slide groove 1261 can guide the movement of the elastic latching portion 210 along the first direction D1.

[0075] Along the first direction D1, the size of the second slide groove 1262 is adapted to the elastic latching part 210 to restrict the movement of the elastic latching part 210 along the first direction D1. That is, when the elastic latching part 210 is located within the second slide groove 1262, the elastic latching part 210 can abut against the groove wall of the second slide groove 1262 along the first direction D1. Therefore, when it is not necessary to release liquid, by switching the position of the elastic latching part 210 into the second slide groove 1262, it is possible to prevent the user from accidentally activating the trigger 200 and causing the valve to open. This reduces the risk caused by improper liquid release.

[0076] In some embodiments, a guide portion 1264 is provided between the first slide groove 1261 and the second slide groove 1262, and the guide portion 1264 guides the elastic latching portion 210 to slide from the first slide groove 1261 to the second slide groove 1262. For example, the guide portion 1264 is a chamfer at the junction of the first slide groove 1261 and the second slide groove 1262. This facilitates the switching of the elastic latching portion 210 between the first slide groove 1261 and the second slide groove 1262, improving the smoothness of the position switching action.

[0077] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the first slide groove 1261 and the second slide groove 1262 penetrate the outer casing 120. The elastic latching portion 210 passes through the outer casing 120 via the first slide groove 1261 or the second slide groove 1262, forming a hand lever 2121 located outside the outer casing 120. That is, the portion of the elastic latching portion 210 located outside the outer casing 120 can serve as the hand lever 2121. The hand lever 2121 allows the user to manually adjust the position of the elastic latching portion 210. For example, there are two elastic latching portions 210. There are also two limiting grooves 126. The two limiting grooves 126 include a first limiting groove 126a and a second limiting groove 126b. The two elastic latching portions 210 include a first elastic latching portion 211 and a second elastic latching portion 212. The first elastic latching portion 211 is located within the first limiting groove 126a, and the second elastic latching portion 212 passes through the second limiting groove 126b and forms the hand lever 2121.

[0078] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the second slide groove 1262 has a latching protrusion 1263 extending along the first direction D1 on its groove wall. The elastic latching part 210 has a latching groove 213 extending along the first direction D1. The latching groove 213 corresponds to and fits the latching protrusion 1263. The latching protrusion 1263 is configured to position the elastic latching part 210, thereby restricting its movement along the second direction D2. When the elastic latching part 210 slides into the first slide groove 1261, the latching protrusion 1263 meets the latching groove 213. The latching protrusion 1263 slides into the latching groove 213 along the first direction D1, thus restricting the elastic latching part 210's movement along the second direction D2. This prevents the elastic latching part 210 in the first slide groove 1261 from sliding into the second slide groove 1262, keeping the trigger 200 in a state where liquid release can be triggered.

[0079] (two) Figure 7 A schematic diagram of another assembly structure of the trigger and reservoir of a liquid release device according to some embodiments of the present disclosure is shown. Figure 7As shown, the liquid reservoir 110 includes a tank body 112, a liquid outlet pipe 111, and a seal 113. The tank body 112 is used to store liquid. The tank body 112 is movably connected to the liquid outlet pipe 111 along a first direction D1. That is, the liquid outlet pipe 111 is movably connected to the tank body 112 along a third direction D3 opposite to the first direction D1. The liquid outlet pipe 111 extends from inside the tank body 112 to the outside of the tank body 112. The portion of the liquid outlet pipe 111 inside the tank body 112 includes a liquid inlet 1112. The end of the liquid outlet pipe 111 away from the tank body 112 includes a liquid outlet 1111, that is, the liquid outlet 1111 is located outside the tank body 112. The seal 113 is fixed inside the tank body 112.

[0080] The outlet pipe 111 can form a valve. A seal 113 is used to seal the inlet 1112. When the seal 113 seals the inlet 1112, the valve is closed. When the outlet pipe 111 moves relative to the tank 112, the seal 113 disengages from the inlet 1112, causing the valve to open. When the valve is open, the inlet 1112 is connected to the inside of the tank 112. Because the pressure inside the tank 112 is higher than the external atmospheric pressure, the liquid inside the tank 112 can enter the outlet pipe 111 through the inlet 1112 and then be released to the outside through the outlet 1111.

[0081] The trigger element 200 can be connected to and move synchronously with the outlet pipe 111. The trigger element 200 can also abut against the elastic element 114. Under the manual action of the user, the trigger element 200 and the outlet pipe 111 can move synchronously along the first direction D1, causing the valve to open. During this process, the elastic element 114 undergoes elastic deformation. When the elastic element 114 recovers its elastic deformation, it can reset the outlet pipe 111 relative to the tank body 112, causing the valve to close.

[0082] (three) Figure 8 A schematic diagram of another assembly structure of the trigger and reservoir of a liquid release device according to some embodiments of the present disclosure is shown. Figure 8 As shown, the liquid reservoir 110 includes a tank body 112, an outlet pipe 111, and a seal 113. The tank body 112 is used to store liquid. The tank body 112 is fixedly connected to the outlet pipe 111. The outlet pipe 111 extends from inside the tank body 112 to the outside of the tank body 112. The portion of the outlet pipe 111 inside the tank body 112 includes an inlet 1112. The inlet 1112 communicates with the inside of the tank body 112. The end of the outlet pipe 111 away from the tank body 112 includes an outlet 1111, i.e., the outlet 1111 is located outside the tank body 112. The seal 113 is located outside the tank body 112 and is inserted into the outlet pipe 111 through the side wall of the outlet pipe 111, used to block the inlet 1112 and the outlet 1111.

[0083] The seal 113 can form a valve. When the seal 113 blocks the inlet 1112 and the outlet 1111, the valve is closed. Movement of the seal 113 relative to the outlet pipe 111 causes the valve to open. When the valve is open, the inlet 1112 and the outlet 1111 are connected. Because the pressure inside the tank 112 is higher than the external atmospheric pressure, the liquid inside the tank 112 can enter the outlet pipe 111 through the inlet 1112 and then be released to the outside through the outlet 1111.

[0084] The trigger element 200 can be connected to and move synchronously with the seal element 113. The trigger element 200 can also abut against the elastic element 114. Under manual operation by the user, the trigger element 200 can move synchronously with the seal element 113, causing the valve to open. During this process, the elastic element 114 undergoes elastic deformation. When the elastic element 114 recovers its elastic deformation, it can reset the seal element 113 relative to the outlet pipe 111, causing the valve to close.

[0085] The following provides a detailed description of the implementation methods of the buffer 300 and the nozzle 130.

[0086] like Figure 2 As shown, the buffer 300 may have a porous structure. For example, the buffer 300 may include one of the following: a sponge block, a cotton ball, silk fabric, porous glass, porous metal, or porous ceramic. Liquid in the liquid release device 001 can be released to the outside through the buffer 300. The buffer 300 can absorb liquid and gradually release it to the outside. This improves the controllability of liquid release and facilitates continuous and sufficient contact of the liquid with the human skin.

[0087] like Figure 2 , Figure 5 and Figure 6 As shown, the handheld body 100 may further include a nozzle 130. The nozzle 130 is configured to receive and position the buffer 300 such that the buffer 300 is opposite to the liquid outlet 1111. A portion of the buffer 300 may be located within and positioned by the nozzle 130, thereby reducing the risk of the buffer 300 accidentally dislodging from the nozzle 130. Another portion of the buffer 300 may be located outside the nozzle 130 to facilitate contact with human skin. Further, the buffer 300 has a first end face 301 and a second end face 302 facing away from each other. The first end face 301 is opposite to the liquid outlet 1111, and the second end face 302 faces outwards for contacting human skin. The first end face 301 and the second end face 302 may or may not be planar. Further, the liquid outlet 1111 is opposite to the first end face 301 along a first direction D1, and the second end face 302 faces outwards along the first direction D1. This buffer 300 can act as a buffer, preventing direct impact on the human body when liquid is released.

[0088] like Figure 2 , Figure 5 and Figure 6 As shown, the buffer 300 is detachably positioned by the nozzle 130. That is, the buffer 300 can be removed from the nozzle 130, which facilitates the replacement of the buffer 300.

[0089] Figure 9 A bottom view of the nozzle of a liquid dispensing device provided according to some embodiments of the present disclosure is shown. In some embodiments, such as Figure 5 and Figure 9 As shown, the nozzle 130 includes a positioning groove 131, which can accommodate and position the buffer 300. The bottom wall of the positioning groove 131 communicates with the liquid outlet 1111. For example, the bottom wall of the positioning groove 131 may be provided with at least one connecting hole 136, which is opposite to and communicates with the liquid outlet 1111. Liquid released from the liquid outlet 1111 can enter the positioning groove 131 through the connecting hole 136. In some embodiments, there are multiple connecting holes 136 of different sizes. For example, a larger connecting hole 136 is located in the middle of the bottom wall of the positioning groove 131, and four smaller connecting holes 136 may be located at the corners of the bottom wall of the positioning groove 131. This facilitates the rapid and uniform entry of liquid into the positioning groove 131 and its transfer to the buffer 300. Therefore, the buffer can be uniformly and quickly wetted by the low-temperature liquid.

[0090] Specifically, such as Figure 5 and Figure 9 As shown, the positioning groove 131 is adapted to the shape and size of the buffer 300. For example, the buffer 300 can be cylindrical, cubic, or other shapes. The size of the buffer 300 can be slightly larger than the size of the positioning groove 131. The buffer 300 is an elastic body. The buffer 300 elastically deforms, and its side abuts against the side wall of the positioning groove 131. After elastic deformation, the buffer 300 can apply an elastic force to the side wall of the positioning groove 131, thereby generating friction between the buffer 300 and the side wall of the positioning groove 131. The friction can prevent the buffer 300 from disengaging from the positioning groove 131. When the user needs to replace the buffer 300, the buffer 300 can be removed from the positioning groove 131.

[0091] In some embodiments, such as Figure 5 and Figure 9 As shown, the sidewall of the positioning groove 131 is provided with at least one positioning protrusion 132. For example, the positioning protrusion 132 is located on the wall surface or at a corner of the sidewall of the positioning groove 131. The number of positioning protrusions 132 can be one, two, or more. The shape of the positioning protrusion 132 relative to the nozzle 130 can be hook-shaped, dot-shaped, or line-shaped. Figure 5 and Figure 9As shown, the positioning protrusion 132 can be in the shape of a barb. The positioning protrusion 132 is configured to insert into and hook the buffer 300 to position the buffer 300. For example, under the action of the positioning protrusion 132, the buffer 300 can further elastically deform and create a depression. The positioning protrusion 132 can be inserted into the depression created by the buffer 300, thereby preventing the buffer 300 from disengaging from the positioning groove 131. Exemplarily, four barb-shaped positioning protrusions 132 are provided on the side wall of the positioning groove 131. The four barb-shaped positioning protrusions 132 are positioned corresponding to the four smaller connecting holes 136 at the corners of the bottom wall of the positioning groove 131, and are located between the bottom wall and the opening of the positioning groove 131. Furthermore, the four positioning protrusions 132 are of the same height along the first direction D1, thereby better fixing the buffer 300 and ensuring that the buffer 300 remains stable during use.

[0092] In other embodiments, the nozzle 130 may be configured as a clamp, which positions the buffer 300 by clamping it. When the user needs to replace the buffer 300, the nozzle 130 can release the buffer 300.

[0093] The nozzle 130 is connected to the housing 120 and communicates with the liquid outlet 1111. In some embodiments, the nozzle 130 and the housing 120 are connected by integral molding. For example, the nozzle 130 and the housing 120 are connected by 3D printing.

[0094] In other embodiments, such as Figure 5 and Figure 9 As shown, the nozzle 130 and the housing 120 are detachably connected via a snap-fit ​​structure. For example, because the internal structure of the housing 120 is relatively complex, it is not convenient to injection mold it together with the housing 120. The nozzle 130 and the housing 120 can be injection molded separately and then assembled together via the snap-fit ​​structure. This can reduce the production cost of the nozzle 130 and the housing 120 and improve production efficiency.

[0095] For example, such as Figure 3 As shown, the limiting part 121 is provided with a through groove 127 and a retaining groove 1271 communicating with the through groove 127. The through groove 127 penetrates the limiting part 121 along the first direction D1. The retaining groove 1271 is located on the side of the limiting part 121 facing the receiving cavity 123 and extends perpendicular to the first direction D1. Figure 5 and Figure 6As shown, the nozzle 130 is provided with a first cantilever 137 extending generally along a first direction D1, and the first cantilever 137 is provided with an elastic protrusion 133 extending perpendicularly to the first direction D1. During assembly, the first cantilever 137 passes through the through groove 127 along a third direction D3, and the elastic protrusion 133 enters into the retaining groove 1271 perpendicularly to the first direction D1. The elastic protrusion 133 is confined within the retaining groove 1271 and forms a snap-fit ​​structure with the retaining groove 1271. In this way, the nozzle 130 can be detachably connected to the housing 120 through the elastic protrusion 133.

[0096] In some embodiments, such as Figure 2 and Figure 5 As shown, the distance L2 between the outlet 1111 and the positioning groove 131 is 10mm to 50mm, forming a buffer space 135 between the outlet 1111 and the positioning groove 131. For example, the distance L2 can be 10mm to 20mm, 20mm to 25mm, 25mm to 30mm, 30mm to 40mm, or 40mm to 50mm. When the buffer member 300 is located in the positioning groove 131, the first end face 301 can be in close contact with the bottom wall of the positioning groove 131. When the outlet 1111 releases liquid, the liquid can enter the positioning groove 131 through the buffer space 135 and the connecting hole 136. The buffer space 135 can reduce the impact force of the liquid on the buffer member 300, thereby reducing the risk of the buffer member 300 being knocked out of the positioning groove 131 by the liquid.

[0097] Figure 10 A schematic diagram of the structure of a liquid release kit provided according to some embodiments of the present disclosure is shown. Figure 11 A further structural schematic diagram of a liquid release kit provided according to some embodiments of the present disclosure is shown. For example... Figure 10 and Figure 11 As shown, this disclosure also provides a liquid release kit 010. The liquid release kit 010 includes a liquid release device 001 and a cap 400. Regarding the embodiment of the liquid release device 001, please refer to the preceding text, and it will not be repeated here. The shape of the cap 400 can be adapted to the shape of the nozzle 130. The cap 400 is detachably connected to the handheld body 100. For example, the cap 400 is detachably connected to the housing 120 or the nozzle 130.

[0098] The cap 400 is configured to cover the first end 101 of the handheld body 100. In some embodiments, the cap 400 is configured to cover the nozzle 130. When the cap 400 covers the nozzle 130, it can also cover the cushion 300. In other embodiments, the cap 400 is configured to at least cover the cushion 300. The cap 400 needs to be opened when the liquid released by the liquid release device 001 comes into contact with human skin. The cap 400 can be closed when the liquid release device 001 is being stored. The cap 400 can have multiple functions. For example, if there is liquid residue on the nozzle 130 or the cushion 300, the cap 400 can block the residual liquid to prevent the user from accidentally touching the liquid.

[0099] In some embodiments, the cap 400 can be closed when the liquid release device 001 releases cryogenic liquid. The cap 400 can contain and buffer the released cryogenic liquid, ensuring the buffer 300 is fully saturated with it, and preventing the buffer 300 from detaching from the nozzle 130. Simultaneously, closing the cap 400 prevents excessive spraying of cryogenic liquid onto the user's skin, which could cause frostbite. When the user uses the liquid release device 001 to remove skin tags, the cap 400 is closed, and the user presses the trigger 200 to release the cryogenic liquid. After the cryogenic liquid has saturated the buffer 300, the user opens the cap 400 and applies pressure to the buffer 300 on the skin tag. The user can release the cryogenic liquid multiple times, repeating the pressure application, depending on the size of the skin tag. During this process, the user should constantly monitor the skin tag and surrounding skin to avoid unnecessary trauma. When pressing the trigger 200 to release the cryogenic liquid, the pressing time should not be too long to avoid wasting the cryogenic liquid. Before applying pressure to the skin tag using the buffer 300, the user can wait a few seconds. For example, if the user presses the trigger 200 for two seconds and then releases it, the buffer 300 will be soaked by the released low-temperature liquid. The user can then wait two seconds before applying pressure to the skin tag to prevent skin damage. The specific pressing and waiting time can be adjusted according to the actual situation. In addition, the cap 400 covers the nozzle 130 and the buffer 300, resulting in a clean and aesthetically pleasing appearance for the liquid release kit 010.

[0100] In some embodiments, the user can leave the cap 400 uncovered when pressing the trigger 200 to release the cryogenic liquid. After the cryogenic liquid releases and wets the buffer 300, the user can directly apply pressure to the skin tag. It should be noted that the user needs to control the pressure and duration when pressing the trigger 200 to avoid wasting the cryogenic liquid.

[0101] In some embodiments, the cap 400 and the nozzle 130 are detachably connected by a tight-fitting structure. In other embodiments, such as Figure 10 and Figure 11As shown, the cap 400 and the nozzle 130 are detachably connected by a snap-fit ​​structure. This design makes it easy for the user to place the cap 400 on the handheld body 100 and also easy for the user to remove the cap 400 from the handheld body 100.

[0102] In some embodiments, the cap 400 may be provided with a first protrusion 420, and the nozzle 130 may be provided with a second protrusion 134. During the process of the cap 400 covering the nozzle 130, the first protrusion 420 moves along the second direction D2 to contact the second protrusion 134, and then the first protrusion 420 can elastically deform slightly and pass over the second protrusion 134. When the cap 400 covers the nozzle 130, the second protrusion 134 can block the first protrusion 420, thereby preventing the first protrusion 420 from moving along the first direction D1. Thus, the second protrusion 134 can prevent the cap 400 from moving along the first direction D1, thereby preventing the cap 400 from detaching from the nozzle 130.

[0103] Furthermore, such as Figure 6 As shown, the nozzle 130 near the trigger 200 has a first edge 1381, a second edge 1382, a third edge 1383, and a fourth edge 1384 connected in sequence. The first edge 1381 is also connected to the fourth edge 1384. The first edge 1381 and the second edge 1382 are opposite each other, and the third edge 1383 and the fourth edge 1384 are opposite each other. A second protrusion 134 is provided on the side of the first edge 1381 away from the trigger 200 and the side of the second edge 1382 away from the trigger 200, and an elastic protrusion 133 is provided on the third edge 1383 and the fourth edge 1384. This facilitates uniform force distribution on the nozzle 130.

[0104] In other embodiments, the cap 400 is provided with a recess, and the nozzle 130 is provided with a protrusion. When the cap 400 covers the nozzle 130, the protrusion is located within the recess, which can prevent the cap 400 from detaching from the nozzle 130.

[0105] In some embodiments, such as Figure 10 and Figure 11 As shown, the end of the housing 120 near the nozzle 130 includes an annular limiting surface 128 facing the cover 400. The shape and size of the opening of the cover 400 are adapted to the annular limiting surface 128 and abut against the annular limiting surface 128 when covering the nozzle 130. During the process of the cover 400 covering the nozzle 130, the annular limiting surface 128 abuts against the cover 400, preventing the cover 400 from continuing to move. By providing the annular limiting surface 128, user operation is facilitated, and the risk of the cover 400 excessively compressing the buffer 300 is reduced.

[0106] Furthermore, when the opening of the cap 400 abuts against the annular limiting surface 128, the outer surface of the cap 400 can be flush with or nearly flush with the outer surface of the housing. This improves the user's grip on the liquid release kit 010 and also enhances its aesthetic appearance.

[0107] Figure 12 A partial structural schematic diagram of the cap of a liquid release kit provided according to some embodiments of the present disclosure is shown. In some embodiments, such as Figure 11 and Figure 12 As shown, the inner wall of the cover 400 is provided with at least one support protrusion 410, which supports the cushioning member 300. The number of support protrusions 410 can be one, two, or more. The shape of the support protrusions 410 relative to the cover 400 can be dot-shaped, line-shaped, grid-shaped, or other shapes. Figure 12 As shown, the size of the support protrusion 410 is relatively small compared to the size of the cover 400, and can be approximated as a point.

[0108] The inner wall of the cover 400 may include an inner peripheral wall and an inner bottom surface 401. The distribution of the support protrusions 410 can be determined according to the contact between the inner wall of the cover 400 and the buffer 300. For example, when the buffer 300 contacts the inner bottom surface 401 of the cover 400, the support protrusions 410 can be located on the inner bottom surface 401 of the cover 400. The support protrusions can extend from the inner bottom surface 401 toward the opening of the cover 400, that is, extend along the third direction D3. The support protrusions 410 can change the contact mode between the cover 400 and the buffer 300 from surface contact to point contact, thereby reducing the contact area between the inner wall of the cover 400 and the buffer 300. This reduces the risk of the buffer 300 sticking to the inner wall of the cover 400.

[0109] In summary, the liquid release device 001 and liquid release kit 010 provided in this disclosure allow a user to hold the handheld body 100 and operate the trigger 200 with one hand. Therefore, the user can perform the liquid release operation with one hand, making it convenient for the user to use the liquid release device 001. The liquid within the liquid release device 001 can be released to the outside through the buffer 300. The buffer 300 can absorb the liquid and gradually release it to the outside. This improves the controllability of the liquid release and facilitates continuous and sufficient contact of the liquid with the human skin. The buffer 300 also acts as a buffer, preventing direct impact on the human body when the liquid is released.
