[0042] The utility model will be further described in detail in combination with the drawings.
[0043] Please refer to Figures 1 to 2 The treatment device provided in the embodiment of the utility model comprises a treatment head 100 and an operating handle 200. The operating handle 200 is provided with a handle part for a user to hold. The treatment head 100 is axially snap-connected with the operating handle 200, and the treatment head 100 is used for focusing ultrasonic energy on the skin to treat the skin. Of course, the treatment device can also adopt ultrasonic, radio frequency phototherapy and the like to treat the skin. The operating handle 200 and the treatment head 100 are at least one of which is provided with an elastic structure, and the elastic structure is axially abutted with the other to provide the other with an axial elastic force.
[0044] The elastic structure can be arranged on the rear end cover 130 of the treatment head 100 close to the operating handle 200 to abut against the front end cover 220 of the treatment head 100, thereby providing the treatment head 100 and the operating handle 200 with a relatively far elastic force. Alternatively, the elastic structure can be arranged on the front end cover 220 of the operating handle 200 close to the treatment head 100 (refer to Figure 4 ), to abut against the rear end cover 130 of the treatment head 100, thereby providing the treatment head 100 and the operating handle 200 with a relatively far elastic force. Alternatively, the rear end cover 130 of the treatment head 100 and the front end cover 220 of the operating handle 200 are both provided with elastic structures to elastically abut against each other, thereby providing the treatment head 100 and the operating handle 200 with a relatively far elastic force.
[0045] Specifically, when the treatment head 100 and the operating handle 200 are assembled, the treatment head 100 and the operating handle 200 are axially snap-connected, so that the treatment head 100 can be detachably assembled on the operating handle 200. When the elastic structure provides the treatment head 100 and the operating handle 200 with a relatively far elastic force, it absorbs the axial gap between the treatment head 100 and the operating handle 200 to absorb the axial gap between the treatment head 100 and the operating handle 200, so that the treatment head 100 can be tightly assembled on the head of the operating handle 200 to prevent the treatment head 100 from easily shaking during application, especially to solve the problem that the treatment head 100 easily shakes after replacement, and the treatment device also has good stability during long-term application.
[0046] In some embodiments, the elastic structure is a first elastic member 300 arranged on one of the operating handle 200 and the treatment head 100. Specifically, the first elastic member 300 is arranged on the rear end cover 130 of the treatment head 100 to abut against the front end cover 220 of the operating handle 200; or, the first elastic member 300 is arranged on the front end cover 220 of the operating handle 200 to abut against the rear end cover 130 of the treatment head 100; or, the first elastic member 300 is arranged on the rear end cover 130 of the treatment head 100, and the first elastic member 300 is also arranged on the front end cover 220 of the operating handle 200, the treatment head 100 and the operating handle 200 elastically abut against each other. In this way, when the treatment head 100 is arranged on the operating handle 200, the treatment head 100 and the operating handle 200 have a large enough elastic force to ensure that the treatment head 100 is stably arranged on the head of the operating handle 200.
[0047] In the first elastic member 300, the elastic structure can be an elastic sheet, an elastic rod, a spring or an elastic pad.
[0048] It can be understood that the elastic structure is the first elastic member 300 arranged and connected with the operating handle 200 and the treatment head 100. In this way, when the elastic structure is designed, the first elastic member with enough elastic force can be selected according to the need, so as to provide a large enough elastic force to the treatment head 100 and the operating handle 200, thereby ensuring that the treatment head 100 can be stably arranged on the operating handle 200.
[0049] In other possible embodiments, the elastic structure is integrally arranged with the end cover of the operating handle 200 or the end cover of the treatment head 100, i.e. the elastic structure is an elastic part integrally arranged with the operating handle 200 or the treatment head 100. Specifically, the rear end cover 130 of the treatment head 100 is integrally arranged with an elastic part, i.e. the elastic structure, which is arranged in a C shape and protrudes outwardly from the rear end cover 130 of the treatment head 100. Thus, when the treatment head 100 is assembled on the head of the operating handle 200, the elastic part abuts against the front end cover 220 of the operating handle 200, thereby providing the treatment head 100 and the operating handle 200 with elastic force for relatively moving away from each other. Alternatively, the front end cover 220 of the operating handle 200 is integrally arranged with an elastic part, i.e. the elastic structure, which is arranged in a C shape and protrudes outwardly from the front end cover 220 of the operating handle 200. When the treatment head 100 is assembled on the operating handle 200, the elastic part abuts against the rear end cover 130 of the treatment head 100, thereby providing the treatment head 100 and the operating handle 200 with elastic force for relatively moving away from each other. Alternatively, the rear end cover 130 of the treatment head 100 is integrally arranged with an elastic part, and the front end cover 220 of the operating handle 200 is integrally arranged with an elastic part. The treatment head 100 and the operating handle 200 elastically abut against each other. In this way, when the treatment head 100 is assembled on the operating handle 200, the treatment head 100 and the operating handle 200 have sufficient elastic force therebetween to ensure that the treatment head 100 is stably assembled on the head of the operating handle 200.
[0050] In a specific embodiment, referring to Figures 2 to 4 , the first elastic member 300 includes an elastic deformation part 310 and two connecting parts 320 connected to two ends of the elastic deformation part 310. The two connecting parts 320 are connected to one of the operating handle 200 and the treatment head 100, and the elastic deformation part 310 elastically abuts against the other. In a specific embodiment, the two connecting parts 320 are connected to the rear end cover 130 of the treatment head 100, and the elastic deformation part 310 protrudes outwardly from the rear end cover 130 of the treatment head 100. Meanwhile, the front end cover 220 of the operating handle 200 is provided with a protruding pressing part 221 corresponding to the elastic deformation part 310. Thus, when the treatment head 100 is assembled on the head of the operating handle 200, the pressing part 221 is pressed against the elastic deformation part 310, and the elastic deformation part 310 elastically deforms inwardly, thereby providing the operating handle 200 with elastic force for moving away from the treatment head 100. In this way, the treatment head 100 is stably buckled and connected to the operating handle 200. Of course, the first elastic member 300 can also be arranged on the front end cover 220 of the operating handle 200, and the elastic deformation part 310 protrudes outwardly from the front end cover 220 of the operating handle 200 to abut against the rear end cover 130 of the treatment head 100.
[0051] It can be understood that the two ends of the first elastic member 300 are connected to the front end cover 220 of the treatment head 100 through the connecting portions 320, and the connecting portions 320 of the two ends of the first elastic member 300 support the elastic deformation portions 310, so that the first elastic member 300 has a large enough elastic potential. Therefore, when the front end cover 220 of the operating handle 200 acts on the first elastic member 300, the first elastic member 300 can provide a large enough elastic force between the treatment head 100 and the operating handle 200, so as to ensure that the treatment head 100 can be stably assembled on the operating handle 200, thereby ensuring the stability of the treatment head 100 in application.
[0052] Further, the elastic deformation portion 310 is provided in a sheet shape. In this way, the elastic deformation portion 310 has a good elastic force, and when the front end cover 220 of the operating handle 200 acts on the elastic deformation portion 310, the elastic deformation portion 310 has a good force on the operating handle 200, so that the treatment head 100 is stably assembled on the operating handle 200. At the same time, when the elastic deformation portion 310 abuts against the front end cover 220 of the operating handle 200, they have a large enough contact area, so as to ensure that the elastic deformation portion 310 is not easily damaged on the front end cover 220 of the operating handle 200 during the application of the treatment head 100, thereby ensuring that the replaced treatment head 100 still has good stability.
[0053] Further, the elastic deformation portion 310 is provided in a C shape. Of course, the elastic deformation portion 310 can also have other structural forms, such as V shape, M shape, etc. In this way, the outer arc surface of the elastic deformation portion 310 abuts against the front end cover 220 of the operating handle 200. It can be understood that the elastic deformation portion 310 is provided in a C shape, and the elastic deformation portion 310 has a good elastic deformation ability during application. The elastic deformation portion 310 can be deformed elastically, so as to absorb the axial tolerance between the operating handle 200 and the treatment head 100, thereby ensuring that treatment heads 100 of various size differences can be stably assembled on the operating handle 200.
[0054] In some embodiments, with reference to Figures 2 to 4, two connecting portions 320 are movably arranged in one of the operating handle 200 and the treatment head 100 to enable relative moving away, i.e. when the opening degree of the elastic deformation portion 310 increases, the two connecting portions 320 move away from each other; on the contrary, when the opening degree of the elastic deformation portion 310 decreases, the two connecting portions 320 move close to each other. In a specific application, the front end cover 220 of the operating handle 200 acts on the elastic deformation portion 310, and the elastic deformation portion 310 increases in tension during elastic deformation, and the two connecting portions 320 move away from each other, so that the elastic deformation portion 310 has a large enough deformation tension, and the elastic deformation portion 310 has a large enough deformation degree in the axial direction, so as to absorb the axial error between the operating handle 200 and the treatment head 100, and further ensure that the treatment head 100 with various size differences can be stably assembled on the operating handle 200. At the same time, when the two connecting portions 320 move away from each other, the elastic deformation portion 310 has a large enough elastic deformation, so as to provide a large enough elastic force between the treatment head 100 and the operating handle 200, and further enable the treatment head 100 to be stably assembled on the operating handle 200.
[0055] In some embodiments, with reference to Figure 2 With Figure 3 The treatment head 100 comprises a treatment head shell 110, a rear end cover 130 and a retaining member 140, wherein the treatment head shell 110 defines an installation cavity 111 for installing the ultrasonic module 120. The rear end portion of the treatment head shell 110 is provided with a decorative seat 150, the rear end cover 130 is connected to the rear end opening of the decorative seat 150, and the rear end cover 130 is provided with a clearance opening 131. The retaining member 140 is connected to the inner side of the rear end cover 130, and a guide gap is provided between the rear end cover 130 and the retaining member 140. The clearance opening 131 is in communication with the guide gap, and the connecting portion 320 is movably arranged in the guide gap, and the elastic deformation portion 310 passes through the clearance opening 131 to abut against the front end cover 220 of the operating handle 200.
[0056] It can be understood that the inside of the rear end cover 130 is provided with the retaining member 140, and the retaining member 140 can conveniently assemble the first elastic member 300 on the rear end cover 130; at the same time, the retaining member 140 and the rear end cover 130 are provided with a guide gap, and the connecting portion 320 of the first elastic member 300 is conveniently assembled in the guide gap, so that the first elastic member 300 can be conveniently assembled on the rear end cover 130, and the connecting portion 320 of the first elastic member 300 has a guiding effect. Therefore, in the specific application process, when the first elastic member 300 is subjected to an external force, the elastic deformation portion 310 of the first elastic member 300 increases in tension at the same time, and the elastic deformation portion 310 can also shrink towards the guide gap, so that the elastic deformation portion 310 generates a large enough elastic deformation to absorb the axial error between the treatment head 100 and the operating handle 200, and at the same time, the first elastic member 300 also provides a large enough elastic force between the treatment head 100 and the operating handle 200 to ensure that the treatment head 100 can be stably assembled on the operating handle 200.
[0057] Further, at least one side of the rear end cover 130 opposite to the retaining member 140 is provided with a positioning groove 132, for example, the positioning groove 132 is arranged on the side of the rear end cover 130 close to the retaining member 140, or the positioning groove 132 is arranged on the side of the retaining member 140 close to the rear end cover 130, or both sides of the rear end cover 130 opposite to the retaining member 140 are provided with the positioning groove 132. The two ends of the positioning groove 132 are provided with positioning faces 1321. The connecting portion 320 is slidably arranged in the positioning groove 132, and the two positioning faces 1321 are used to limit the distance of the sliding of the two connecting portions 320, so as to limit the tension of the elastic deformation portion 310.
[0058] Specifically, when the elastic deformation portion 310 is subjected to the force of the front end cover 220 of the operating handle 200, the tension of the elastic deformation portion 310 increases continuously, and the two connecting portions 320 move away from each other along the positioning groove 132, and the two connecting portions 320 abut against the limiting faces at the two ends of the positioning groove 132, so as to limit the opening of the elastic deformation portion 310 from being too large, and further ensure that the elastic deformation portion 310 has a good elastic force in a long time application process. Therefore, the first elastic member 300 provides a large enough elastic force between the treatment head 100 and the operating handle 200 for a long time, so that the treatment head 100 can be stably assembled on the operating handle 200.
[0059] In some embodiments, with reference to Figure 2 and Figure 3At least one of the end of the operating handle 200 opposite to the treatment head 100 is provided with a plug-in part 160, which is inserted into the other one to be axially buckled. The plug-in part 160 can be provided on the rear end cover 130 of the treatment head 100 to be inserted and connected to the front end cover 220 of the operating handle 200. Alternatively, the plug-in part 160 can be provided on the front end cover 220 of the operating handle 200 to be inserted and connected to the rear end cover 130 of the treatment head 100. Alternatively, the rear end cover 130 of the treatment head 100 and the front end cover 220 of the operating handle 200 are both provided with plug-in parts 160 to be buckled to each other.
[0060] Further, the plug-in part 160 and the elastic structure are both provided on one of the treatment head 100 and the operating handle 200. If the plug-in part 160 is provided on the rear end cover 130 of the treatment head 100, the elastic structure is correspondingly provided on the front end cover 220 of the operating handle 200. Meanwhile, if the plug-in part 160 is provided on the front end cover 220 of the operating handle 200, the elastic structure is correspondingly provided on the rear end cover 130 of the treatment head 100.
[0061] It can be understood that the plug-in part 160 and the elastic structure are both provided on the rear end cover 130 of the treatment head 100, or the plug-in part 160 and the elastic structure are both provided on the front end cover 220 of the operating handle 200. In this way, the interference between the plug-in part 160 and the retaining part 140 of the first elastic member 300 is effectively avoided, thereby facilitating the design and installation of the treatment head 100 and the operating handle 200.
[0062] Further, the elastic structure and the plug-in part 160 are both provided on the treatment head 100, more specifically, the elastic structure and the plug-in part 160 are both provided on the rear end cover 130 of the treatment head 100. It can be understood that when the plug-in part 160 and the elastic structure are provided on the rear end cover 130 of the treatment head 100, the plug-in part 160 and the elastic structure occupy less space inside the treatment head 100, thereby saving the internal space of the treatment head 100, so that the internal space of the treatment head 100 can be used to install the ultrasonic module 120.
[0063] In some embodiments, referring to Figure 5 and Figure 6The operation handle 200 comprises a handle shell 210, a front end cover 220, a locking seat 230 and a button 260. The handle shell 210 is provided with a receiving cavity along the axial direction of the handle shell 210, and the receiving cavity is used to mount a control panel to control the working state of the treatment device. The front end cover 220 is connected to the front end of the handle shell 210, and the front end cover 220 is provided with a clearance hole 222 for inserting the insertion part 160. The inner side of the front end cover 220 is fixedly provided with a retaining cover 240, and the locking seat 230 is transversely and slidingly arranged in a guide channel between the front end cover 220 and the retaining cover 240. The side of the insertion part 160 is provided with a clamping groove 161 (see Figure 2 ), and the locking seat 230 is provided with a locking part 231, which is clamped in the clamping groove 161, thereby axially limiting the insertion part 160, and further realizing the axial clamping connection between the treatment head 100 and the operation handle 200. Meanwhile, the second elastic member 250 is arranged on the front end cover 220 or the handle shell 210 and abuts against the locking seat 230, and the second elastic member 250 is used to maintain the axial clamping connection between the insertion part 160 and the locking seat 230. The button 260 is arranged on the side of the handle shell 210 and abuts against the locking seat 230 in the transverse direction, and the button 260 can be pressed to push the locking seat 230 to slide transversely. The second elastic member 250 and the button 260 act on the locking seat 230 in opposite directions.
[0064] In specific applications, when the treatment head 100 needs to be replaced, the user presses the button 260 towards the inner side of the handle shell 210, the button 260 overcomes the elastic force of the second elastic member 250 to push the locking seat 230 to slide transversely, the locking part 231 of the locking seat 230 is separated from the clamping groove 161 of the insertion rod, thereby releasing the axial limitation between the treatment head 100 and the operation handle 200, and the treatment head 100 can be conveniently replaced.
[0065] The application further discloses a treatment instrument comprising the treatment device.
[0066] It can be understood that the treatment instrument adopts the treatment device, and the user uses the elastic structure between the treatment head 100 and the operation handle 200 when replacing the treatment head 100, thereby providing the elastic axial force between the treatment head 100 and the operation handle 200.
