[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] If the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0037] Handheld microcurrent beauty devices are widely welcomed by consumers in the consumer market. The operating part of the beauty device is the head component, and the fixed part is the body component for manual grip. In the prior art, the head of the handheld beauty device product is prone to loosening during long-term use, and even after falling, the head and the body are separated and broken. The reason is that due to the shape requirements of the head component and the need to meet sufficient wiring space, the head cannot be arranged with enough screws, otherwise it will occupy the wiring space and cause wiring difficulties. Generally, only two screws can be arranged, resulting in the problem of unreliable fixation of the connection structure between the operating part and the fixed part.

[0038] Specific reasons refer to Figure 1 As shown, a connecting column 1 and a limiting plate 4 are provided on the side of the working part close to the fixing part, and the connecting column 1 is located on the side of the connection, and the limiting plate 4 is surrounded by the side of the connecting column 1, so that a cavity for wiring is reserved in the middle. A fixing plate 2 is provided on the side of the fixing part close to the working part, and a cavity for wiring is also reserved in the middle of the fixing plate 2. During the assembly process, the ends of the connecting column 1 and the limiting plate 4 are pressed against the surface of the fixing plate 2, and the fixing plate 2 and the connecting column 1 are locked by the screws 3 to realize the assembly and fixation of the working part and the fixing plate 2. However, during the operation of the working part, due to the lack of restrictions on the surrounding side of the working part, the screws 3 will still loosen due to the vibration generated by the operation, and there is a problem of the working part loosening or even falling off.

[0039] To improve the above problems, the embodiment of the present application provides a fixing structure 100, which can be adapted to the connection of components of a working device such as a beauty instrument 1000. The limit of the connection of the components of the working device is improved to improve the problem of the above working part being loose or even falling off.

[0040] See also Figure 2 As shown, the fixing structure 100 includes a first connecting member 110, a second connecting member 120 and at least one locking member 130. The first connecting member 110 and the second connecting member 120 can respectively correspond to the fixing part and the working part in the above-mentioned prior art, and after assembly, they are locked and fixed by the locking member 130.

[0041] Please continue reading Figure 3 and Figure 4As shown, the first connecting member 110 includes a fixing plate 111 and a first limiting block 112. The fixing plate 111 is provided with at least one through hole 1111, so as to be connected with the second connecting member 120 after the locking member 130 is provided with the through hole 1111, thereby fixing the first connecting member 110 and the second connecting member 120. One end of the first limiting block 112 is connected with the fixing plate 111, and the other end extends toward the direction of the second connecting member 120, so as to limit the surface of the second connecting member 120 and strengthen the connection stability between the first connecting member 110 and the second connecting member 120.

[0042] Specifically, the fixing plate 111 can be a horizontally placed plate, the first limit block 112 is set in a vertical state, the first limit block 112 can be an integrally formed structure with the fixing plate 111, and the first limit block 112 is vertically set on one side of the fixing plate 111 close to the second connecting member 120.

[0043] The second connecting member 120 includes at least one connecting column 121, each connecting column 121 is provided with a connecting hole 1211, and each connecting hole 1211 is coaxially arranged with a through hole 1111, so that the locking member 130 passes through the through hole 1111 and the connecting hole 1211 in sequence to fix the first connecting member 110 and the second connecting member 120. One end of the connecting column 121 extends toward the second connecting member 120, so that during the assembly process, the end of the connecting column 121 abuts against the fixing plate 111, and at least part of the peripheral side surface of the connecting column 121 fits with the first limiting block 112, so that the first limiting block 112 limits the displacement of the side of the connecting column 121, reduces the vibration of the connecting column 121 during operation, and improves the problem of the first connecting member 110 and the second connecting member 120 loosening due to vibration.

[0044] Specifically, the number of the connecting posts 121 can be one, two, three, etc., and can be set according to actual needs. For example, when it is necessary to lay wires, the number of the connecting posts 121 can be adaptively reduced to reserve sufficient wiring space. In this embodiment, the number of the connecting posts 121 can be two, and accordingly, the number of the through holes 1111 opened on the fixing plate 111 can be two.

[0045] The locking members 130 and the connecting posts 121 are disposed one by one in correspondence, and each locking member 130 is respectively penetrated by a corresponding set of connecting holes 1211 and through holes 1111 to fix the first connecting member 110 and the second connecting member 120 .

[0046] Specifically, the number of the locking members 130 may be one, two, three, etc. corresponding to the connecting column 121. In this embodiment, the number of the locking members 130 may be two. The locking member 130 may be a screw, and an internal thread may be correspondingly provided inside the connecting hole 1211 to be thread-locked with the threaded portion of the locking member 130. After the threaded section of the locking member 130 passes through the through hole 1111 of the fixing plate 111, it is screwed into the connecting hole 1211 under the action of an external force, and finally the nut of the locking member 130 is pressed against the through hole 1111 of the fixing plate 111, thereby locking the first connecting member 110 and the second connecting member 120. Furthermore, a nut can be set at the end of the threaded section of the locking piece 130, and a groove for fixing the nut can be set at the end of the connecting hole 1211 away from the fixing plate 111, or after the locking piece 130 is penetrated by the connecting hole 1211, part of the threaded section connected to the nut is exposed to further improve the connection strength of the locking piece 130.

[0047] It can be understood that the penetration direction of the locking member 130 can be changed. In other embodiments, an internal thread can be set in the through hole 1111. The locking member 130 penetrates the connecting hole 1211 and is connected to the through hole 1111. The nut structure can also be adaptively adjusted. Please refer to the above embodiment for details.

[0048] In other embodiments, the locking member 130 may also be a pin structure, and after the through hole 1111 and the connecting hole 1211 are penetrated, the first connecting member 110 and the second connecting member 120 are fixed. Furthermore, in order to ensure the stability of the locking member 130, a retaining spring or a bayonet pin may be provided at its end, which will not be elaborated in detail here.

[0049] In some embodiments, the second connection member 120 further includes a second stopper 122, which is fixedly disposed on the side of each connection column 121, and at least a portion of the surface of the second stopper 122 is in contact with the first stopper 112. By providing the second stopper 122, the contact area between the first stopper 112 and the second connection member 120 can be increased, further improving the connection stability between the first connection member 110 and the second connection member 120.

[0050] Specifically, the second connecting member 120 also includes a second shell 123, and the connecting column 121 and the second limit block 122 are fixedly arranged at one end of the second shell 123 close to the first connecting member 110, and protrude relative to the second shell 123, extending toward the outside of the second shell 123 to abut against the fixing plate 111 of the first connecting member 110.

[0051] In one embodiment, the second limit block 122 and the connecting column 121 are in an integrated structure, and the second limit block 122 is fixedly connected to the outer surface of the connecting column 121. The second limit block 122 and the connecting column 121 can be integrally injection molded, thereby improving the connection strength between the second limit block 122 and the connecting column 121. During the assembly process, the second limit block 122 and the connecting column 121 are both in contact with the first limit block 112, thereby improving the connection stability between the first connecting member 110 and the second connecting member 120.

[0052] In other embodiments, the second limit block 122 may also be spaced apart from the connecting column 121, that is, the side of the second limit block 122 is not connected to the connecting column 121, and a gap is left between the second limit block 122 and the connecting column 121, so as to realize various arrangement structures of the second limit block 122. One end of the second limit block 122 on the same side as the connecting column 121 is fixed to the first housing 113, and the connection stability between the first connecting member 110 and the second connecting member 120 can also be improved under the restriction of the first limit block 112.

[0053] In one embodiment, the second limit block 122 is an annular structure with an accommodating cavity 1221 on the inner side, and the first limit block 112 is disposed in the accommodating cavity 1221 and fits with the inner wall surface of the second limit block 122. Specifically, two connecting pillars 121 are disposed on both sides of the second limit block 122, and the outer wall surfaces of the second limit block 122 and the connecting pillars 121 together form an annular cylindrical structure to improve the connection strength between the second limit block 122 and the connecting pillars 121.

[0054] In one embodiment, the first connecting member 110 also includes a first shell 113, which is connected to the side of the fixing plate 111 and has a groove 114 between the first shell 113 and the first limit block 112. The connecting column 121 and the second limit block 122 are both plugged into the groove 114, so that the two opposite sides of the connecting column 121 and the second limit block 122 are simultaneously limited by the first shell 113 and the first limit block 112, thereby further reducing the displacement of the second connecting member 120 caused by vibration during operation.

[0055] Specifically, one end of the first shell 113 close to the second connecting member 120 is arranged in a recessed structure, the side of the fixing plate 111 is connected to the bottom side of the recess of the first shell 113, and the first limit block 112 is located on the side of the fixing plate 111 away from the first shell 113, and extends toward the direction of the second connecting member 120, thereby forming a groove 114 between the first limit block 112 and the first shell 113.

[0056] During the assembly process of the first connector 110 and the second connector 120, the second stopper 122 and the connecting column 121 are inserted into the groove 114. After the end surface abuts the fixing plate 111, the first stopper 112 is fitted with the surface of the second stopper 122 and the connecting column 121, so that the first stopper 112 and the second stopper 122 are restricted on both sides by the first stopper 112 and the first shell 113 to form a sandwich structure. Then, the first connector 110 and the second connector 120 are locked by the locking member 130, and the connection strength of the first connector 110 and the second connector 120 is significantly improved.

[0057] See also Figure 5 As shown, in one embodiment, the first connecting member 110 also includes a sealing ring 124, and a sealing groove 1122 is provided at one end of the second limiting block 122 close to the groove 114, and the sealing ring 124 is sleeved in the sealing groove 1122 to strengthen the connection strength between the first shell 113 and the second limiting block 122.

[0058] Specifically, the sealing ring 124 is pressed tightly between the first shell 113 and the second limit block 122, thereby filling the gap between the first shell 113 and the second limit block 122, improving the connection strength between the first shell 113 and the second limit block 122, and further reducing the vibration of the second connecting member 120 during operation.

[0059] In other embodiments, the sealing ring 124 may also be replaced by elastic materials such as sealing strips and buffer blocks, which can fill the gap between the first shell 113 and the second limit block 122 .

[0060] In one of the embodiments, one end of the first limit block 112 away from the fixed plate 111 is flush with the other end of the second limit block 122 away from the fixed plate 111, that is, the side surface of the first limit block 112 completely covers the surface of the second limit block 122 and the connecting column 121, thereby further enhancing the limiting effect of the first limit block 112 on the second limit block 122 and the connecting column 121.

[0061] See again Figure 4 As shown, in one embodiment, the first limit block 112 is a ring structure with a wiring cavity 1121 provided inside, and the wiring cavity 1121 is used to lay wires. The wiring cavity 1121 is connected to the internal cavities of the first shell 113 and the second shell 123 respectively, and the connecting wires of the electronic components of the two can be laid through the wiring cavity 1121, thereby realizing the circuit connection of the internal electronic components of the two.

[0062] See also Figure 6As shown, the embodiment of the present application further provides a beauty instrument 1000, including the fixing structure 100 in any of the above embodiments. The beauty instrument 1000 may include a head assembly, a body assembly, a base 200 and a power cord 300. The head assembly is mounted on one end of the body assembly, and the end of the body assembly away from the head assembly may be placed on the base 200, and the power cord 300 is electrically connected to the base 200. The fixing structure 100 may be applied between adjacent components to improve the connection strength between the components.

[0063] This embodiment has the fixing structure 100 in any of the above embodiments, and therefore has all the beneficial effects of the fixing structure 100 in any of the above embodiments, which will not be described in detail here.

[0064] In one embodiment, the first connecting member 110 is a body component, and the second connecting member 120 is a head component. During the operation of the beauty instrument 1000, the body component is a fixed part that is manually held by the operator, and the head component is an operating part. By applying the fixing structure 100 of the present application to the head component and the body component, the vibration of the head component during the operation is reduced, and the phenomenon of the head component becoming loose or even falling off due to long-term operation is improved.

[0065] In other embodiments, the specific structures of the first connecting member 110 and the second connecting member 120 may be interchangeable. For example, the first connecting member 110 may be used as a head component and the second connecting member 120 may be used as a body component, both of which may achieve the same technical effect.

[0066] It is understandable that the beauty instrument 1000 provided in the above embodiment can only be used as an example application scenario of the fixing structure 100. The fixing structure 100 provided in the present application can also be applied to other working devices, such as shavers, epilators, electric toothbrushes, etc.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
