Detailed implementation manners

[0024] To enable those skilled in the art of this technical field to better understand the solutions of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the utility model.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model.

[0026] Please refer to Figures 1 to 5 , an embodiment of the present utility model provides a skin treatment device 10. The skin treatment device 10 may include a main unit 100, an electrode head 200, and an elastic limiting member 300. The main unit 100 may be provided with an assembly groove 110. The electrode head 200 is detachably installed in the assembly groove 110. The elastic limiting member 300 may be installed on the main unit 100. When the electrode head 200 is located in the assembly groove 110, the elastic limiting member 300 can movably press against the side surface of the electrode head 200 to limit the electrode head 200 in the assembly groove 110. Thus, compared with the skin treatment device in the related art, the electrode head 200 of the skin treatment device 10 in the present application can be detached relative to the main unit 100, facilitating the user to separately clean the electrode head 200 after using the skin treatment device 10, rather than cleaning the entire skin treatment device 10. Therefore, the easily contaminated area of the electrode head 200 can be cleaned more efficiently and specifically, which helps to reduce the risk of water ingress into the main unit 100 due to improper cleaning, and further helps to reduce the risk of short circuit of the main unit 100.

[0027] In addition, when the electrode head 200 is installed in the assembly groove 110, the elastic limiting member 300 can press against the side surface of the electrode head 200, which helps to limit the electrode head 200 in the assembly groove 110, so that the electrode head 200 will not become loose when in the working state.

[0028] In some embodiments, the host 100 may have a side wall 120 forming the assembly groove 110, the side wall 120 may be provided with a limiting space 121 and a limiting hole (not shown), the limiting hole may be connected to the limiting space 121 and the assembly groove 110, the elastic limiting component 300 may include an elastic member 310 and a sphere 320, the elastic member 310 and the sphere 320 may be located in the limiting space 121, the outer diameter of the sphere 320 is greater than the aperture of the limiting hole, one end of the elastic member 310 may abut against the side wall 120, and the other end of the elastic member 310 may abut against the sphere 320, so that the sphere 320 is partially located in the assembly groove 110. Among them, the elastic member 310 may be a spring or a spring sheet, etc., the sphere 320 may be set in a spherical shape, and the sphere 320 may be made of materials such as stainless steel, iron or glass.

[0029] During the process of installing the electrode head 200 in the assembly groove 110, the ball 320 can roll on the side of the electrode head 200, and the electrode head 200 pushes the ball 320 to squeeze the elastic member 310, and the ball 320 moves from the limiting hole to the limiting space 121, so that the electrode head 200 can be assembled into the assembly groove 110. When the electrode head 200 is assembled into the assembly groove 110, the ball 320 will be pressed against the side of the electrode head 200 under the action of the elastic member 310, so that the electrode head 200 is limited in the assembly groove 110.

[0030] During the process of removing the electrode head 200 from the assembly groove 110, the user can directly pull the electrode head 200 out of the assembly groove 110, and the ball 320 can roll on the side of the electrode head 200, so that the friction between the ball 320 and the electrode head 200 is small, thereby helping the user to quickly and conveniently remove the electrode head 200 from the assembly groove 110 of the main unit 100.

[0031] See also Figure 3 In some embodiments, the side wall 120 may also be provided with a mounting hole (not shown) connected to the limiting space 121, and the mounting hole may be located on the side of the side wall 120 away from the assembly groove 110. The elastic limiting component 300 may also include a first cover body 330, which is detachably connected to the side wall 120 and located in the mounting hole. For example, the first cover body 330 may be connected to the side wall 120 by a threaded connection or a snap connection, and one end of the elastic member 310 may abut against the first cover body 330, and the other end of the elastic member 310 may abut against the ball 320.

[0032] During the installation of the elastic limiting component 300, first, the operator places the sphere 320 in the limiting space 121 through the installation hole on the side wall 120, and then passes one end of the elastic member 310 through the installation hole and extends into the limiting space 121, so that one end of the elastic member 310 abuts against the sphere 320. Secondly, the first cover 330 is then fixedly connected to the side wall 120, and the first cover 330 is fixed to the side wall 120, so that the other end of the elastic member 310 abuts against the first cover 330, thereby effectively squeezing the sphere 320, so that the sphere 320 partially protrudes from the assembly groove 110, and the expected limiting effect is achieved.

[0033] In this way, since the first cover body 330 is detachably connected to the side wall 120 and located in the mounting hole, it is helpful to put the ball 320 and the elastic member 310 into the limiting space 121 from the mounting hole in turn, thereby making the assembly process of the elastic limiting component 300 simpler, without the need for special tools, and more convenient to operate.

[0034] In some embodiments, the elastic member 310 may be a spring, and a conical abutment portion 331 is provided at one end of the first cover 330 facing the elastic member 310, and one end of the elastic member 310 facing away from the sphere 320 abuts against the conical abutment portion 331 and is sleeved on the outer periphery of the conical abutment portion 331. Specifically, the conical abutment portion 331 may be arranged in a conical shape, and one end of the elastic member 310 facing away from the sphere 320 may abut against the conical abutment portion 331 and be sleeved on the outer periphery of the conical abutment portion 331. The conical abutment portion 331 may guide and constrain the elastic member 310, so that the conical abutment portion 331 may locate the position of the elastic member 310, so that the two ends of the elastic member 310 may stably abut against the sphere 320 and the conical abutment portion 331, respectively, thereby helping to reduce the risk of displacement of the elastic member 310 in the limiting space 121.

[0035] In addition, the conical abutment portion 331 can better distribute and transmit the pressure of the elastic member 310 on the ball 320, making the force transmission more uniform, avoiding local stress concentration, reducing the risk of fatigue of the elastic member 310 and equipment damage, and extending the service life.

[0036] Furthermore, the assembler can accurately abut the elastic member 310 via the conical abutment portion 331 , and can position the elastic member 310 without complicated calibration steps, thereby helping to improve the assembly efficiency of the elastic limiting component 300 .

[0037] See also Figure 3, in some embodiments, the elastic limiting member 300 may further include a second cover 340. The second cover 340 is detachably connected to the side wall 120. For example, the second cover 340 may be connected to the side wall 120 by snap connection or threaded connection. The second cover 340 may be located on the side of the side wall 120 facing the assembly groove 110. The second cover 340 may be provided with a limiting hole. The sphere 320 may be abutted between the elastic member 310 and the second cover 340, and a part of the sphere 320 protrudes from the second cover 340 into the assembly groove 110.

[0038] During the installation process of the elastic limiting member 300, first, an operator may insert one end of the elastic member 310 into the limiting space 121 so that one end of the elastic member 310 abuts against the side wall 120, and then place the sphere 320 into the limiting space 121 so that the sphere 320 can abut against the other end of the elastic member 310. Secondly, then fixedly connect the second cover 340 to the side wall 120 so that the sphere 320 can protrude from the limiting hole of the second cover 340 into the assembly groove 110 to achieve the desired limiting effect.

[0039] In this way, since the second cover 340 is detachably connected to the side wall 120, it helps to install the sphere 320 and the elastic member 310 in the limiting space 121, so that the assembly process of the elastic limiting member 300 is relatively simple, without special tools and the operation is relatively convenient.

[0040] In some embodiments, the host 100 may have a side wall 120 forming the assembly groove 110. The elastic limiting member 300 may include a limiting cylinder, an elastic member 310 and a sphere 320. The limiting cylinder is detachably installed on the side wall 120 and is located in the limiting space 121. For example, the limiting cylinder may be connected to the side wall 120 by threaded connection or insertion (interference fit). The limiting cylinder may be provided with a limiting space 121 and a limiting hole. The limiting hole may communicate with the limiting space 121. The outer diameter of the sphere 320 may be greater than the aperture of the limiting hole. One end of the elastic member 310 may abut against the limiting cylinder, and the other end of the elastic member 310 may abut against the sphere 320 so that a part of the sphere 320 protrudes from the assembly groove 110, thereby limiting the electrode head 200 located in the assembly groove 110. Specifically, the limiting cylinder is generally made of materials such as metal. During the assembly process of the elastic limiting member 300, an operator may first abut one end of the elastic member 310 against the bottom of the limiting cylinder, then install the sphere 320 in the limiting space 121 in the limiting cylinder and abut the sphere 320 against the other end of the elastic member 310, and then use a fixture to seal the limiting cylinder so that the aperture of the limiting hole is smaller than the outer diameter of the sphere 320, thereby helping a part of the sphere 320 to protrude from the assembly groove 110.

[0041] Thus, the elastic limiting component 300 is integrated into a pre-assembled module, greatly simplifying the on-site assembly process and enabling the operator to quickly and accurately install the elastic limiting component 300 on the side wall 120 without complex assembly steps or professional tools.

[0042] Please refer to Figure 3 and Figure 5 , in some embodiments, a limiting groove 210 may be provided on the side surface of the electrode head 200. When the electrode head 200 is located in the assembly groove 110, a part of the elastic limiting component 300 is located in the limiting groove 210. Specifically, when the electrode head 200 is located in the assembly groove 110, a part of the sphere 320 of the elastic limiting component 300 is located in the limiting groove 210, which is more conducive to limiting the electrode head 200 in the assembly groove 110, and further helps to reduce the risk of the electrode head 200 falling off from the assembly groove 110 during use.

[0043] In some embodiments, the limiting groove 210 may be provided around the circumference of the electrode head 200. Specifically, when the assembly groove 110 is designed to be square, the outer contour of the electrode head 200 is also designed to be square accordingly so that the electrode head 200 can be installed in the assembly groove 110. On this basis, the limiting groove 210 may be provided around the circumference of the electrode head 200. No matter in which direction the electrode head 200 is placed into the assembly groove 110, it can naturally guide a part of the structure of the elastic limiting component 300 (such as the sphere 320) into the limiting groove 210 on the electrode head 200 without special attention to the orientation of the electrode head 200, simplifying the assembly process.

[0044] In some embodiments, the electrode head 200 may have an electrode 230, and the main body 100 may further include a circuit board (not shown in the figure). The circuit board may be installed on the main body 100. When the electrode head 200 is located in the assembly groove 110, the elastic limiting component 300 may be electrically connected to the electrode 230 and the circuit board. Thus, by integrating the electrical connection and the mechanical limiting function, the skin treatment device 10 of the present application helps to simplify the electrical connection steps during the assembly and maintenance of the skin treatment device 10.

[0045] In addition, the elastic limiting component 300 may be electrically connected to the electrode and the circuit board. For example, the sphere 320 of the elastic limiting component 300 may be electrically connected to the electrode and the circuit board, which helps to ensure the stability and efficiency of the current conduction between the electrode and the circuit board, reduces the energy loss or treatment effect fluctuation caused by poor contact, and thus helps to improve the reliability of the treatment of the skin treatment device 10.

[0046] In some embodiments, the electrode head 200 may include an electrode head housing 220. The electrode head housing 220 may be provided with a negative pressure groove 221 and an electrode head air passage 222. The electrode head air passage 222 may communicate with the negative pressure groove 221. The main body 100 may include a main body housing 130. The side wall 120 may be a part of the main body housing 130. The main body housing 130 may be provided with an assembly groove 110 and a main body air passage 132. The main body air passage 132 may communicate with the assembly groove 110 and the electrode head air passage 222. The skin treatment device 10 further includes a sealing ring 400, such as a silicone sealing ring or a rubber sealing ring, etc. The sealing ring 400 may be located in the assembly groove 110. The sealing ring 400 may surround the connection part of the electrode head air passage 222 and the main body air passage 132, and abut between the electrode head housing 220 and the main body housing 130, so as to help ensure the sealing performance of the electrode head air passage 222 and the main body air passage 132 at the connection part of the main body 100 and the electrode head 200.

[0047] Among them, the electrode head 200 is provided with a plurality of electrodes 230, and the electrodes 230 are respectively arranged on both sides of the negative pressure groove 221. The main body 100 may also be provided with an exhaust fan. The exhaust fan sucks air through the main body air passage 132, the electrode head air passage 222 and the negative pressure groove 221, so as to form a negative pressure effect in the negative pressure groove 221. When the user's skin contacts the electrodes 230 of the electrode head 200 and approaches the negative pressure groove 221, the user's skin can be sucked into the negative pressure groove 221, so that the skin located in the negative pressure groove 221 is roughly arc-shaped, which helps to increase the effective contact area between the skin located in the negative pressure groove 221 and the electrodes 230, and further helps to improve the beauty effect of the skin treatment device 10.

[0048] In some embodiments, one of the electrode head housing 220 and the main body housing 130 is provided with a sealing ring limiting groove 410, and the sealing ring 400 may be embedded in the sealing ring limiting groove 410. Specifically, the shape of the sealing ring 400 may be adapted to the shape of the sealing ring limiting groove 410, which helps to limit the sealing ring 400, and further helps to reduce the risk of the sealing ring 400 being lost when the electrode head 200 is disassembled from the main body 100, and also reduces the risk of the sealing ring 400 shifting between the electrode head 200 and the main body 100.
