[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0032] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] The charging electrodes in existing beauty devices are generally connected to the internal control circuit board by welding with wires. After long-term use, the solder joints are easy to fall off, which can easily lead to poor contact problems, thereby losing the conductive function and affecting the normal operation of the beauty device. Moreover, since it is impossible to stably fix and clamp, the stability and accuracy of welding cannot be guaranteed, which directly leads to low production efficiency and low product qualification rate, increasing the difficulty of welding and increasing labor costs. Therefore, in order to solve the above technical problems, the present application proposes at least the following embodiments.

[0034] The utility model provides a beauty instrument 100, please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the beauty instrument 100 includes a housing 10, a control circuit board 20 disposed in the housing 10, and a charging electrode 30 exposed outside the housing 10, and the charging electrode 30 is used to be electrically connected to an external power supply device.

[0035] In this embodiment, the charging electrode 30 is exposed outside the shell 10, which may include a situation where the charging electrode 30 is protruding outside the shell 10, or a situation where the charging electrode 30 is flush with the surface of the shell 10, or a situation where the charging electrode 30 is recessed at a certain distance from the surface of the shell 10. The purpose is to enable an external power supply device to be electrically connected to the charging electrode 30 to charge the beauty instrument 100.

[0036] In this embodiment, a rechargeable battery 12 is disposed in the housing 10 . The rechargeable battery 12 is electrically connected to the control circuit board 20 . An external power supply device is electrically connected to the charging electrode 30 to charge the rechargeable battery 12 .

[0037] It should be understood that the technical solution of the present invention is an improvement on the connection method between the charging electrode 30 and the control circuit board 20. The other parts and related functions in the beauty instrument 100 of the present invention are all prior art, so they are not described in detail here, and those skilled in the art should also know and master them.

[0038] The beauty instrument 100 in this embodiment further includes an elastic connector 40, one end of which is connected to the control circuit board 20, and the other end of which is connected to the charging electrode 30. The elastic connector 40 conducts the electrical connection between the control circuit board 20 and the charging electrode 30, and the other end of the charging electrode 30 is exposed to the housing 10 for electrical connection with an external power supply device. In this way, the elastic connector 40 connects the external power supply device, the charging electrode 30 and the control circuit board 20 to form a charging circuit, so that the external power supply device can charge the beauty instrument 100.

[0039] The utility model sets an elastic connector 40, connects one end of the elastic connector 40 to the control circuit board 20, and connects the other end of the elastic connector 40 to the charging electrode 30, and the elastic connector 40 conducts the electrical connection between the control circuit board 20 and the charging electrode 30, thereby completing the assembly of the charging electrode 30. This assembly method is convenient and fast, eliminates the welding process in the prior art, greatly reduces the assembly difficulty and assembly cost, and the connection is stable and reliable, and can maintain a good electrical connection to ensure the normal operation of the beauty instrument 100.

[0040] In this embodiment, a pair of charging electrodes 30 are provided, and a pair of elastic connectors 40 are correspondingly provided. Each elastic connector 40 electrically connects each charging electrode 30 and the control circuit board 20. When the charging electrode 30 is electrically connected to an external power supply device, a charging circuit can be formed. At this time, electric energy can be transmitted from the external power supply device to the beauty instrument 100, thereby charging the beauty instrument 100.

[0041] Of course, in other embodiments, the number of the charging electrodes 30 may also be other integers greater than 2, and the present application does not limit the number of the charging electrodes 30 .

[0042] As an example, please refer to Figure 3The elastic connecting member 40 includes a first conductive member 41 and a second conductive member 42. At least one of the first conductive member 41 and the second conductive member 42 is elastic. One end of the first conductive member 41 and / or the second conductive member 42 is connected to the control circuit board 20. The other ends of the first conductive member 41 and the second conductive member 42 are close to each other to form an elastic clamping opening 43. The charging electrode 30 is inserted into the elastic clamping opening 43.

[0043] In the initial state, the diameter of the elastic clamping opening 43 is smaller than the diameter of the charging electrode 30. When the charging electrode 30 is inserted into the elastic clamping opening 43, the charging electrode 30 squeezes the first conductive member 41 and the second conductive member 42 toward the outside thereof to achieve squeeze contact, so that the contact between the charging electrode 30 and the elastic connecting member 40 is tighter. At the same time, at least one of the first conductive member 41 and the second conductive member 42 is connected to the charging electrode 30 and energized, thereby forming an effective electrical connection. The connection reliability between the charging electrode 30 and the elastic connecting member 40 of the utility model is high, and accidental slippage and the like will not occur.

[0044] In this embodiment, at least one of the first conductive member 41 and the second conductive member 42 is elastic, that is, the first conductive member 41 or the second conductive member 42 is elastic, or both the first conductive member 41 and the second conductive member 42 are elastic. The purpose is to form an elastic clamp 43 between the first conductive member 41 and the second conductive member 42, thereby forming a stable elastic clamping fixation for the charging electrode 30.

[0045] In this embodiment, it is preferred that both the first conductive member 41 and the second conductive member 42 are elastic, so that the charging electrode 30 can be elastically clamped and fixed more stably and reliably.

[0046] In this embodiment, one end of the first conductive member 41 and / or the second conductive member 42 is connected to the control circuit board 20, that is, only at least one of the first conductive member 41 and the second conductive member 42 needs to be connected to the control circuit board 20 to electrically connect the control circuit board 20 and the charging electrode 30.

[0047] In this embodiment, it is preferred that both the first conductive member 41 and the second conductive member 42 are connected to the control circuit board 20 , so that a stable connection between the elastic connecting member 40 and the control circuit board 20 can be maintained.

[0048] Please refer to Figure 4 In some embodiments, the charging electrode 30 includes a first end 31 and a second end 32 arranged along its length direction and opposite to the first end 31. The first end 31 is inserted into the elastic clamp 43 for being electrically connected to the first conductive member 41 and / or the second conductive member 42. The second end 32 is exposed from the shell 10 for being electrically connected to an external power supply device.

[0049] The charging electrode 30 in this embodiment is preferably a long strip structure, which can be directly installed in the housing 10 and connected to the elastic connector 40 during assembly, which is convenient for assembly, and has a small size and occupies a small space. Of course, the charging electrode 30 can also be in other shapes, such as a curved structure, etc., the purpose of which is that one end of the charging electrode 30 is connected to the elastic connector 40, and the other end is exposed to the housing 10.

[0050] In this embodiment, the charging electrode 30 forms a brim portion 33 at the second end 32, and the shell 10 is provided with a through hole 11 corresponding to the charging electrode 30. The brim portion 33 of the charging electrode 30 is installed at the through hole 11 to fix the charging electrode 30 to prevent the charging electrode 30 from slipping out of the shell 10, and at the same time facilitate the connection of the charging electrode 30 with an external power supply device.

[0051] In some embodiments, the elastic connecting member 40 also includes a conductive member 44, which is connected to the control circuit board 20, and the first conductive member 41 and the second conductive member 42 are respectively fixedly connected to the two ends of the conductive member 44, and the conductive member 44 conducts the electrical connection between the first conductive member 41 and / or the second conductive member 42 and the control circuit board 20.

[0052] In the actual assembly process, the conductive member 44 can be fixed on the control circuit board 20 by screws, and the first conductive member 41 and the second conductive member 42 are fixedly connected to the two ends of the conductive member 44 respectively.

[0053] In this embodiment, the conductive member 44 conducts electrical connection between the first conductive member 41 and / or the second conductive member 42 and the control circuit board 20 , that is, the conductive member 44 only needs to conduct electrical connection between at least one of the first conductive member 41 and the second conductive member 42 and the control circuit board 20 .

[0054] In some embodiments, the conductive member 44, the first conductive member 41 and the second conductive member 42 are an integrally formed structure, for example, they can be made of thin-walled metal plates through sheet metal stamping and stretching processes. Therefore, the elastic connector 40 of the utility model is simple to process and has high processing efficiency, which further reduces the production cost and can improve the integrity of the entire structure and is not easy to separate, thereby making the elastic connector 40 have good electrical connection stability.

[0055] The first conductive member 41 and the second conductive member 42 are bent upward from both ends of the conductive member 44 and are close to each other to form an elastic clamping opening 43. The elastic connector 40 of the utility model has a simple structure, is easy to process and produce, and has good electrical connection stability.

[0056] In some embodiments, the elastic connector 40 is a metal spring having good electrical conductivity and elastic deformation properties, which can realize elastic clamping and fixing of the charging electrode 30 and electrical connection between the charging electrode 30 and the control circuit board 20 .

[0057] In addition, the contact area between the metal spring and the charging electrode 30 and the control circuit board 20 is large, and the connection reliability is high, ensuring that the beauty instrument 100 can be charged and used normally.

[0058] For some examples, please refer to Figure 5 The elastic clamp 43 includes a first area 431 and a second area 432. The first area 431 is connected to the second area 432. The area of ​​the first area 431 is larger than that of the second area 432.

[0059] The first conductive member 41 and the second conductive member 42 include a first section 45 and a second section 46 respectively. The first section 45 is connected to the conductive member 44, and the second section 46 is connected to the first section 45. The two first sections 45 are close to each other to form a first area 431, and the two second sections 46 are close to each other to form a second area 432. The charging electrode 30 is inserted in the second area 432.

[0060] Among them, the first section 45 and the first area 431 enclosed by it are used to provide the second section 46 with more elastically deformable areas, which facilitates the elastic deformation of the second section 46 and thus has better elastic deformation performance, so that the charging electrode 30 can be squeezed outward to form a stable electrical contact when inserted, and can rebound in time when the charging electrode 30 is pulled out.

[0061] In this embodiment, the two second sections 46 are arranged in a "V"-shaped structure, which has good elastic clamping strength. When assembled, the two second sections 46 elastically clamp the charging electrode 30, which has good stability and is not easy to slip. Of course, the two second sections 46 can also be arranged in other shapes, such as circular, elliptical, etc., but are not limited thereto.

[0062] In some embodiments, the elastic clamp 43 further includes a third region 433, the third region 433 is connected to the second region 432, and the area of ​​the third region 433 is smaller than the area of ​​the second region 432;

[0063] The first conductive member 41 and the second conductive member 42 further include a third section 47 , respectively. The third section 47 is connected to the second section 46 , and the two third sections 47 are close to each other to form a third area 433 .

[0064] The third area 433 is in a tightened state relative to the second area 432 , playing a role of gathering and tightening, so that the two second sections 46 can be close to each other to generate an elastic clamping force, so as to clamp the charging electrode 30 more stably.

[0065] In some embodiments, the inclinations of the first section 45 , the second section 46 , and the third section 47 gradually decrease, that is, the first section 45 , the second section 46 , and the third section 47 move closer to the inner side of the conductive member 44 .

[0066] In this embodiment, the conductive member 44, the first section 45, the second section 46 and the third section 47 are connected to form a non-closed triangle shape, which has a stable structure and is not prone to deviation to affect the fixation of the charging electrode 30. It is also compact and occupies little space.

[0067] In some embodiments, the elastic clamp 43 further includes a fourth region 434;

[0068] The first conductive member 41 and the second conductive member 42 further include a fourth section 48 , respectively. The fourth section 48 is connected to the third section 47 . The two fourth sections 48 are separated from each other and enclose a fourth region 434 . The fourth region 434 is connected to the third region 433 .

[0069] During installation, the charging electrode 30 can be slid from the fourth area 434 and the third area 433 into the second area 432 and clamped and fixed by the two second sections 46; alternatively, the charging electrode 30 can be slid from the first area 431 into the second area 432 and clamped and fixed by the two second sections 46.

[0070] In some embodiments, the fourth region 434 is in a trumpet shape. That is, the diameter of the fourth region 434 gradually increases from the connection with the third region 433 to the direction away from the third region 433, which facilitates the sliding of the charging electrode 30 from the fourth region 434 into the third region 433 and the second region 432, plays a guiding role, and improves the accuracy of the installation of the charging electrode 30 and the convenience of installation.

[0071] Of course, the fourth area 434 may also be in other shapes, and is not limited thereto.

[0072] In some embodiments, the connection between the conductive member 44, the first section 45, the second section 46, the third section 47 and / or the fourth section 48 has an arc, that is, a smooth transition of the arc is adopted, so that the entire elastic connector 40 has good elastic deformation performance and avoids easy breakage.

[0073] In some embodiments, the other end of the elastic connector 40 is detachably connected to the charging electrode 30, and assembly and disassembly are performed using the elasticity of the elastic connector 40. In this way, when the charging electrode 30 has poor contact or fails, the user can quickly detach the charging electrode 30 from the elastic connector 40 and replace it, ensuring that the user can continue to use it.

[0074] In summary, the utility model sets an elastic connector 40, connects one end of the elastic connector 40 to the control circuit board 20, and connects the other end of the elastic connector 40 to the charging electrode 30, and the elastic connector 40 conducts the electrical connection between the control circuit board 20 and the charging electrode 30, thereby completing the assembly of the charging electrode 30. This assembly method is convenient and fast, eliminates the welding process in the prior art, greatly reduces the assembly difficulty and assembly cost, and the connection is stable and reliable, and can maintain a good electrical connection to ensure the normal operation of the beauty instrument 100.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the utility model are still within the scope of protection of the utility model.
