[0043] The smearing device is a structure for uniformly smearing the skin care product with fluidity such as fluid or paste on the skin surface of the user. In use, the smearing device is connected to the opening end of the container of the skin care kit.

[0044] In related technologies, the smearing device is in some use scenarios that need electricity, and a battery is arranged in the smearing device. In conventional technologies, a charging connector is arranged on the shell of the smearing device to charge the battery. However, the arrangement of the charging connector affects the overall sealing of the smearing device, which is not conducive to the waterproof and dustproof of the smearing device.

[0045] Therefore, the embodiments of the present application provide a smearing device, which adopts a first charging coil and a second charging coil connected by magnetic attraction, and the first charging coil and the second charging coil are connected by a wireless connection mode, so that a corresponding through hole structure does not need to be opened on the shell, and the charging demand of the battery pack can be met. Thus, the waterproof and dustproof performance of the smearing device is better.

[0046] Firstly, please refer to Figure 1 , Figure 2 and Figure 5The embodiment of the present application provides a smearing device 100, which comprises a shell 10 with a containing cavity, a first charging coil 20, a battery pack 30 and a master control board 40. The first charging coil 20, the master control board 40 and the battery pack 30 are arranged in the containing cavity, the first charging coil 20 is electrically connected with the master control board 40, the battery pack 30 is electrically connected with the master control board 40, and the first charging coil 20 is used for being wirelessly electrically connected with an external charging device; the shell 10 is provided with a liquid guide channel 10a for fluid circulation.

[0047] It can be understood that the shell 10 is a main structural part of the smearing device 100 and plays a fixing and bearing role for various components, wherein the first charging coil 20, the battery pack 30 and the master control board 40 are arranged in the containing cavity of the shell 10, and the first charging coil 20 is magnetically interacted with the external charging device to realize wireless charging. Of course, the shell 10 of the smearing device 100 should have the liquid guide channel 10a to enable the skin care product to pass through the liquid guide channel 10a and leave the shell.

[0048] Optionally, the first charging coil 20 should be an electromagnetic conversion structure such as a charging coil, which is magnetically interacted with the charging coil of the external charging device to realize electromagnetic energy conversion and achieve the goal of wireless charging.

[0049] In summary, the smearing device 100 provided by the present application can meet the charging demand of the battery pack 30 through wireless charging without opening a through hole structure on the shell 10, so that the overall consistency of the shell 10 of the smearing device 100 is higher, and the waterproof and dustproof performance is better.

[0050] The smearing device 100 provided by the present application is provided with the first charging coil 20 in the shell 10, the first charging coil 20 is wirelessly electrically connected with the external charging device, so that the battery pack 30 can be charged when being wirelessly electrically connected with the external charging device through the first charging coil 20, the hole structure of the shell 10 is reduced or even avoided to ensure the integrity of the shell and further improve the waterproof and dustproof performance of the smearing device.

[0051] Please refer to FIG. In some embodiments, the smearing device 100 further comprises a first magnetic member 21, the first charging coil 20 is arranged around the periphery of the first magnetic member 21, and the first magnetic member 21 is used for being magnetically connected with the external charging device.

[0052] It can be understood that, in the charging process, the first magnetic member 21 is magnetically attracted with the magnetic structure or permanent magnet of the external charging device to stabilize the first charging coil 20 in the charging process and improve the charging efficiency of the first charging coil 20.

[0053] Meanwhile, the first charging coil 20 is wound around the periphery of the first magnetic member 21, which can effectively reduce the height or thickness of the stack of the first charging coil 20 and the first magnetic member 21, so that the whole is more slim, and winding the first charging coil 20 around the periphery of the first magnetic member 21 can further improve the stability of the first charging coil 20 during the charging process, reducing the probability of deviation or vibration.

[0054] Alternatively, in other implementations, the first magnetic member 21 can also be arranged around the periphery of the first charging coil 20, at this time, the first magnetic member 21 is a circular magnet, which can also meet the requirements that the height or thickness of the stack of the first magnetic member 21 and the first charging coil 20 is small, and the stability of the first charging coil 20 during operation is high.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, the smearing device 100 further comprises a support 50, the support 50 is arranged in the shell 10, and the support 50 is used for fixing the first charging coil 20, the battery pack 30 and the main control board 40.

[0056] It can be understood that the support 50 fixes and supports the first charging coil 20, the battery pack 30 and the main control board 40, so as to reduce the shaking of each component during use.

[0057] The structure of the support 50 is not limited, and can meet the above fixing and supporting requirements.

[0058] Specifically, please refer to Figures 2 to 4 In some embodiments, the support 50 comprises a main body part 51 and a supporting part 52 arranged on the main body part 51, the main body part 51 is a hollow structure, the main control board 40 is arranged in the main body part 51, and the first charging coil 20 and the battery pack 30 are arranged on the supporting part 52.

[0059] Here, the main body part 51 is the main structure of the support 50, which fixes the main control board 40, and the supporting part 52 is a structure part extending outward from the main body part 51, which fixes the first charging coil 20 and the battery pack 30, and arranges the first charging coil 20 and the battery pack 30 outward to facilitate later maintenance.

[0060] Please refer to Figure 4 In some embodiments, the main control board 40 is arranged in the main body part 51, and the inner wall of the main body part 51 is provided with a slot 51a matched with the main control board 40.

[0061] Here, the main control board 40 is fixed in the slot 51a of the main body part 51 by plugging, which facilitates the disassembly and assembly of the main control board 40 in the main body part 51.

[0062] The support part 52 comprises a bottom plate 521 provided on the main body part 51 and two side plates 522 arranged between the bottom plate 521 and the main body part 51. The first charging coil 20 is arranged on the battery pack 30, the battery pack 30 is arranged on the bottom plate 521, and the two side plates 522 are arranged on opposite sides of the battery pack 30.

[0063] Here, the bottom plate 521, the two side plates 522, and the outer wall of the main body part 51 form a containing space for mounting the first charging coil 20 and the battery pack 30, facilitating the disassembly and assembly of the first charging coil 20 and the battery pack 30 on the support part 52.

[0064] Please refer to Figure 5 In some embodiments, the smearing device 100 further comprises a magnetic isolation member 53 arranged between the first charging coil 20 and the battery pack 30.

[0065] It can be understood that the magnetic isolation member 53 has a corresponding magnetic isolation effect, for example, the magnetic isolation member 53 can be a neodymium iron boron permanent magnet, a nickel zinc ferrite thin magnetic sheet, a manganese zinc ferrite thin magnetic sheet, a flexible ferrite magnetic sheet, etc. At the same time, the structural form of the magnetic isolation member 53 includes but is not limited to a sheet structure, a block structure, and a strip structure, etc.

[0066] The magnetic isolation member 53 increases the magnetic flux of the first charging coil 20, can isolate the contact between the metal object and the electromagnetic signal, prevent the attenuation interference of the metal conductor to the magnetic field, play a role of metal isolation, prevent energy waste, improve the charging efficiency, and at the same time can increase the heat dissipation area, which is beneficial to the heat dissipation of the first charging coil 20, so as to improve the stability of the first charging coil 20 in the electromagnetic conversion process.

[0067] Please refer to Figure 2 , Figure 3 and Figure 5 In one embodiment, the shell 10 is in a strip shape and has a smearing surface 10b at one end of the length direction Y, and the liquid guide channel 10a penetrates the smearing surface 10b.

[0068] The first charging coil 20, the battery pack 30, and the main control board 40 are distributed along the first direction X, and the first direction X is perpendicular to the length direction Y of the shell 10. The first charging coil 20 is arranged to face the circumferential surface of the shell 10.

[0069] It can be understood that the length of the shell 10 should be greater than the width, for example, the shell 10 is in a cylindrical structure, the length direction of the cylindrical structure is the axial direction of the cylindrical structure, and then the smearing surface 10b is the end surface of the cylindrical structure, and the liquid guide channel 10a can extend along the axial direction of the cylindrical structure.

[0070] The first direction X can be the radial direction of the cylindrical structure. Therefore, the first charging coil 20, the battery pack 30 and the main control board 40 are arranged in the radial direction of the cylindrical structure. This makes the first charging coil 20 face the circumferential side with a sufficient angle, so as to facilitate wireless charging with external charging devices.

[0071] Secondly, please refer to Figure 1 , Figure 2 and Figure 5 This application also provides an electronic device, including a charging base 300 and the above-mentioned applicator 100. The charging base 300 includes a housing 301 and a second charging coil 303. The second charging coil 303 is disposed inside the housing 301 and is used to make a wireless connection with the first charging coil 20 of the above-mentioned applicator 100.

[0072] Understandably, the housing 301 is the supporting part of the electronic device 300, used to fix and support the second charging coil 303, and when the second charging coil 303 is in use, the housing 301 abuts against the casing.

[0073] The second charging coil 303 should be an electromagnetic conversion structure such as a charging coil, electrically connected to the power supply of the peripheral device, thereby realizing the conversion of electrical energy into magnetic energy. Then, the second charging coil 303 interacts with the first charging coil 20 magnetically, using the first charging coil 20 to convert magnetic energy into electrical energy and store it in the battery pack 30.

[0074] In use, the electronic device provided by this utility model has its housing 10 of the applicator 100 placed on the outer shell 301 of the charging base 300, and the second charging coil 303 wirelessly connected to the first charging coil 20 to charge the battery pack 30 of the applicator 100.

[0075] Please refer to Figure 1 In some embodiments, the outer wall of the housing 10 of the applicator 100 is arc-shaped, and the outer shell 301 has a placement surface 302 that is adapted to the outer wall of the housing of the applicator 100, and the placement surface 302 is an arc-shaped placement surface 302.

[0076] Understandably, during wireless charging of the applicator 100 and the electronic device 300, the placement surface 302 of the housing 301 abuts against the outer wall of the applicator 100's housing. Here, the placement surface 302 is the surface that directly contacts the housing 10, and it should be adapted to the outer wall of the housing 10. That is, if the outer wall of the housing 10 is curved, then the placement surface 302 is also a curved placement surface. Simultaneously, the curved placement surface better restricts the housing 10 from sliding freely. It also reduces changes to the shape of the outer wall of the housing 10, primarily by adjusting the contour shape of the placement surface 302.

[0077] Meanwhile, the shell 10 of the smearing device 100 also needs to be connected with the skin care kit, which makes the overall length of the shell 10 after connecting the skin care kit longer. Therefore, the outer wall of the shell 10 is designed as an arc shape, and the first charging coil 20, the battery pack 30 and the main control board 40 are sequentially arranged in the first direction X, so that when the shell 10 is placed on the placement surface 302, the gravity direction of each component is perpendicular to the placement surface 302, and the stability of the smearing device 100 during wireless charging on the charging base 300 is further improved.

[0078] In this way, the arc-shaped placement surface is matched with the arc-shaped outer wall of the shell of the smearing device 100, so as to improve the stability of the shell of the smearing device 100 placed on the placement surface 302 of the shell 301.

[0079] Of course, in other embodiments, the shape of the placement surface 302 can also be adjusted. For example, the outer wall of the shell is a plane, and the placement surface 302 is also a plane.

[0080] Please refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the charging base 300 further comprises a second magnetic member 304, and the second charging coil 303 is arranged around the periphery of the second magnetic member 303, and the second magnetic member 303 is used for magnetic connection with the first magnetic member 21 of the smearing device 100.

[0081] Understandably, the second charging coil 303 is the main structural member for magnetic induction interaction with the first charging coil 20 of the smearing device 100. Specifically, the second charging coil 303 is electrically connected with the power supply of the external device, so as to realize the conversion of electric energy into magnetic energy. Then, the second charging coil 303 interacts with the first charging coil 20 for magnetic induction, and the first charging coil 20 converts the magnetic energy into electric energy and stores it in the battery pack 30.

[0082] Of course, the second charging coil 303 also includes other structures, such as a strap for limiting the second charging coil 303, and an insulating layer covering the second charging coil 303.

[0083] In addition, during the charging process, the second magnetic member 303 is magnetically attracted to the first magnetic member 21, so as to fix the setting position of the first charging coil 20 and the second charging coil 303 during the charging process, and improve the conversion efficiency of electromagnetic energy.

[0084] Meanwhile, the second charging coil 303 is wound around the periphery of the second magnetic member 303, which can effectively reduce the stacking height or thickness of the second charging coil 303 and the second magnetic member 303, so that the whole is more slim, and winding the second charging coil 303 around the periphery of the second magnetic member 303 can further improve the stability of the second charging coil 303 during the charging process, reduce the probability of deviation or vibration, especially when the first magnetic member 21 is also arranged in the wound first charging coil 20, the first magnetic member 21 and the second magnetic member 303 are magnetically connected with each other, and the second charging coil 303 can also quickly align the first charging coil 20, so as to realize the timeliness of wireless charging, similar to plug-in charging, which can charge after completing the plug-in action.

[0085] Optionally, in other embodiments, the second magnetic member 303 can also be arranged around the periphery of the second charging coil 303, at this time, the second magnetic member 303 is a circular magnet, which can also meet the requirements of small height or thickness of the second magnetic member 303 and the second charging coil 303 after stacking, and high stability of the second charging coil 303 during operation.

[0086] In this way, the second magnetic member 303 is magnetically connected with the first magnetic member 21 of the smearing device 100, so as to improve the connection stability of the shell 301 of the electronic equipment 300 and the shell of the smearing device 100 after contact connection, and the second charging coil 303 and the first charging coil 20 are magnetically connected with each other, and the generated electric energy is stored in the battery pack 30 of the smearing device 100.

[0087] In a third aspect, referring to Figure 1 The skin care kit provided by the utility model has better waterproof and dustproof performance on the basis of the smearing device 100.

[0088] The skin care kit provided by the utility model has better waterproof and dustproof performance on the basis of the smearing device 100.

[0089] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
