[0055] The present utility model provides a personal care device. Personal care devices generally refer to those tools or instruments used for daily personal hygiene and beauty care, including but not limited to electric shavers, electric toothbrushes, hair clippers, facial cleansing devices, and the like.

[0056] In the embodiments of the present utility model, please refer to Figures 1 to 3 , Figures 9 to 11 and Figures 16 to 18 , the personal care device 100 includes a main body case 10 and a charging assembly 20. Among them, a charging jack 11 is provided on the main body case 10, and the charging assembly 20 is disposed inside the main body case 10 and corresponds to the charging jack 11. The charging assembly 20 includes a sealing bracket 21, a charging interface 22, and a seal 23. The charging interface 22 is hermetically fixed to the sealing bracket 21 and is exposed outside the main body case 10 through the charging jack 11; the seal 23 is disposed around the charging jack 11, and the seal 23 is clamped between the main body case 10 and the sealing bracket 21.

[0057] The main body housing 10 serves as the outer shell and support structure of the entire personal care device 100, providing a cavity for accommodating the charging assembly 20 and other electronic components, and at the same time providing a power interface through the charging jack 11. The charging assembly 20 provides electrical energy support for the operation of the personal care device 100. The charging assembly 20 includes a sealing bracket 21, a charging interface 22, and a seal 23. Among them, the sealing bracket 21 cooperates with the main body housing 10 to support or fix the charging interface 22 and the seal 23. The charging interface 22 is connected to an external power adapter for charging. The charging interface 22 is exposed outside the main body housing 10 through the charging jack 11, which is easy for users to identify and operate. The exposure of the charging interface 22 enables users to easily identify and connect to the charging position without having to disassemble or open other parts of the personal care device 100, simplifying the operation steps.

[0058] The charging interface 22 is directly or indirectly sealed and fixed to the sealing bracket 21 to prevent external water or dust from entering the interior of the personal care device 100 through the gap between the charging interface 22 and the seal. The seal 23 is disposed around the charging jack 11, and the seal 23 is clamped between the main body housing 10 and the sealing bracket 21. This can prevent moisture and dust from entering the device interior through the gap between the charging jack 11, the main body housing 10, and the sealing bracket 21, thereby improving the waterproof and dustproof level of the device.

[0059] In this embodiment, double waterproofing is achieved by directly or indirectly sealing and fixing the charging interface 22 to the sealing bracket 21 and clamping the seal 23 between the main body housing 10 and the sealing bracket 21, thereby significantly improving the waterproof level of the personal care device 100, and further reducing the risk of damage to the device caused by water ingress. Compared with forming a sealing structure with a reused housing or a movement bracket, in this embodiment, an independent sealing bracket 21 is adopted, and more precise sealing materials and structures can be used without being restricted by the design of the housing or the movement bracket to form a sealing structure with higher flexibility or adaptability. At the same time, the independent sealing bracket 21 is convenient for replacement and repair. In this way, users can extend the service life of the personal care device 100 at a lower cost. In addition, the independent sealing bracket 21 enables the charging assembly 20 in the personal care device 100 to be independently developed and optimized, which helps to simplify the assembly process and improve production efficiency.

[0060] Further, referring to Figure 3 、 Figure 5 、 Figure 11 、 Figure 13 and Figure 18 , the sealing bracket 21 is provided with a glue groove 211, and the glue groove 211 is provided with an assembly port 2112 corresponding to the charging jack 11; the charging interface 22 is installed in the assembly port 2112; a glue-containing space 2111 is formed by enclosing the inner wall surface of the glue groove 211 and the outer peripheral surface of the charging interface 22, and the glue-containing space 2111 is filled with sealant.

[0061] In this embodiment, the sealant can be filled in the sealant accommodation space 2111. The seal 23 can provide a preliminary waterproof and dustproof effect, while the sealant in the sealant accommodation space 2111 can further fill the tiny gaps that the seal 23 cannot completely cover, providing a more comprehensive sealing effect. At the same time, after curing, the sealant can bond the charging interface 22 and the seal bracket 21, so that the two maintain a relative position relationship, thereby improving the overall structural stability.

[0062] Further, the seal 23 includes first seal rings 231a / 231b / 231c extending along the center line direction of the charging jack 11; a surrounding wall 12 is arranged on the inner side of the main body shell 10 around the charging jack 11; one end of the seal bracket 21 close to the charging jack 11 is placed inside the surrounding wall 12; the first seal rings 231a / 231b / 231c are clamped between the surrounding wall 12 and the seal bracket 21.

[0063] In this embodiment, when installing the seal bracket 21, the surrounding wall 12 can play a positioning role, thereby improving the assembly efficiency. The first seal rings 231a / 231b / 231c are clamped between the surrounding wall 12 and the seal bracket 21, so that external moisture cannot enter the interior of the personal care device 100 from the gap between the surrounding wall 12 and the seal bracket 21.

[0064] Further, referring to Figures 16 to 18 , the seal 23 further includes a transverse seal ring 232c, and the transverse seal ring 232c is connected to one end of the first seal ring 231c away from the charging jack 11; the seal bracket 21 includes a main body portion 213 and a baffle 215 surrounding the side wall of the main body portion 213; the transverse seal ring 232c is clamped between the side surface of the baffle 215 facing the charging jack 11 and the end surface of the surrounding wall 12 away from the charging jack 11 to seal the gap between the seal bracket 21 and the main body shell 10.

[0065] In this embodiment, the transverse seal ring 232c becomes the second waterproof barrier. Even if the waterproof performance of the first seal ring 231c deteriorates or fails, the transverse seal ring 232c can prevent external water from penetrating into the interior of the personal care device 100 through the gap between the main body shell 10 and the seal bracket 21.

[0066] Further, the seal bracket 21 has a bottom end wall, and an assembly opening 2112 is formed in the bottom end wall; a connection opening 216 is also formed in the bottom end wall, and a surrounding plate 217 is protruded from the inner wall surface of the bottom end wall around the connection opening 216; the personal care device 100 further includes a sealing cap 60 and a sealing plug 70, the sealing cap 60 includes a cover 61 and a connection column 62 connected to the inner wall surface of the cover 61, and the connection column 62 can be movably arranged inside the surrounding plate 217 through the connection opening 216, so that the cover 61 can open or block the charging jack 11; the sealing plug 70 blocks one end of the surrounding plate 217 away from the connection opening 216.

[0067] In this embodiment, the connecting post 62 of the sealing cap 60 can move freely through the connection port 216 within the space formed by surrounding the baffle 217, so that the cover 61 of the sealing cap 60 can be conveniently opened or blocked to the charging jack 11. Meanwhile, the sealing plug 70 blocks one end of the baffle 217 away from the connection port 216, preventing the sealant from flowing into the space within the baffle when the sealant is filled in the sealant space 2111, thereby affecting the movement of the connecting post 62.

[0068] In one embodiment, referring to Figures 1 to 13 , the charging assembly 20 further includes a decorative member 24 installed on the periphery of the charging jack 11, and the decorative member 24 is in limit fit with the main body case 10 in the opening direction of the charging jack 11; the decorative member 24 is sleeved on the outside of the charging interface 22.

[0069] In this embodiment, the decorative member 24 is usually made of metal. The decorative member 24 provides necessary mechanical support to ensure the stability and durability when the data cable interface is inserted. Meanwhile, the inner wall of the decorative member 24 also provides guidance for the data cable interface to facilitate the docking of the data cable interface with the charging interface 22.

[0070] Further, referring to Figures 1 to 5 The seal 23 further includes a transverse seal ring 232a, and the transverse seal ring 232a is connected to one end of the first seal ring 231a close to the charging jack 11; the transverse seal ring 232a includes a first side surface and a second side surface arranged along the center line direction of the charging jack 11; the first side surface abuts against the side surface of the seal bracket 21 facing the charging jack 11; the second side surface abuts against the main body case 10 and the decorative member 24 to seal the gap between the seal bracket 21 and the main body case 10 and the decorative member 24.

[0071] In this embodiment, the transverse seal ring 232a extends transversely. The transverse direction is perpendicular to or intersects with the center line direction of the charging jack 11. The cooperation between the transverse seal ring 232a and the first seal ring 231a enables the seal bracket 21 to achieve waterproofing in two directions simultaneously.

[0072] In one embodiment, the seal 23 includes a transverse seal ring 232b, and the transverse seal ring 232b is connected to one end of the first seal ring 231b close to the charging jack 11, and the transverse seal ring 232b is clamped between the seal bracket 21 and the main body case 10.

[0073] In this embodiment, since the lateral sealing ring 232b is connected to one end of the first sealing ring 231b close to the charging jack 11, this means that additional sealing protection is provided at a key interface (charging jack 11) of the razor. This helps prevent moisture or dust from entering the interior of the razor through the charging jack 11 and via the gap between the sealing bracket 21 and the main body case 10 during the charging process, thereby improving the overall waterproof and dustproof performance of the razor.

[0074] Further, referring to Figures 9 to 13 , the seal 23 further includes a second sealing ring 233 extending in the same direction as the first sealing ring 231b, and the second sealing ring 233 is connected to one end of the lateral sealing ring 232b away from the first sealing ring 231b; the decorative member 24 includes a first positioning section 241 and a sealing section 242 connected along the center line direction of the charging jack 11; the first positioning section 241 is in limiting cooperation with the main body case 10 in the opening direction of the charging jack 11; the sealing section 242 extends along the center line direction of the charging jack 11, and the second sealing ring 233 is clamped between the sealing section 242 and the sealing bracket 21.

[0075] In this embodiment, the function of the second sealing ring 233 is to seal the gap between the outer side surfaces of the sealing bracket 21 and the decorative member 24. On the one hand, it prevents water outside the personal care device 100 from entering the glue-containing space 2111 through the gap between the outer side surfaces of the sealing bracket 21 and the decorative member 24. On the other hand, it prevents the sealing glue from flowing out of the glue-containing space 2111 through this gap when the glue-containing space 2111 is filled with the sealing glue.

[0076] Since the first positioning section 241 of the decorative member 24 is in limiting cooperation with the main body case 10 in the center line direction of the charging jack 11, this precise positioning mechanism helps reduce the assembly error and improve the assembly accuracy. At the same time, the clamping relationship between the sealing section 242 and the second sealing ring 233 may also make the entire assembly process simpler and faster, thereby improving the production efficiency.

[0077] The lateral sealing ring 232b, the first sealing ring 231b, and the second sealing ring 233 cooperate to achieve multiple sealing guarantees, significantly enhancing the sealing performance of the razor in the area of the charging jack 11, effectively preventing external impurities such as moisture and dust from penetrating into the interior of the razor through the gap, thereby improving the waterproof and dustproof grade of the product.

[0078] Further, referring to Figures 9 to 13 , the decorative member 24 further includes a second positioning section 243 placed in the glue-containing groove 211; the second positioning section 243 is in limiting cooperation with the inner wall surface of the glue-containing groove 211 in the opening direction of the charging jack 11; the second positioning section 243 extends toward the surrounding wall 12 and covers the splicing seam between the second sealing ring 233 and the sealing bracket 21.

[0079] In this embodiment, a second positioning section 243 is added to the decorative member 24 and placed in the glue storage groove 211, and is in limit fit with the inner wall surface of the glue storage groove 211 in the central line direction of the charging jack 11. This design effectively combines the decorative member 24 with the main body structure of the razor (such as the main body shell 10, the sealing bracket 21, etc.) more tightly. The addition of the second positioning section 243 not only enhances the positioning accuracy of the decorative member 24 itself, but also effectively blocks the potential penetration path by covering the splicing seam between the second sealing ring 233 and the sealing bracket 21, thereby improving the waterproof and dustproof performance of the razor in the area of the charging jack 11.

[0080] In one embodiment, referring to Figure 3 、 Figures 6 to 8 、 Figure 11 、 Figure 14 、 Figure 15 and Figure 18 ,the glue storage groove 211 is provided with an installation opening 2113 corresponding to the assembly opening 2112; the charging assembly 20 further includes a circuit board 30, the circuit board 30 is electrically connected to the charging interface 22, and the circuit board 30 covers the installation opening 2113; the circuit board 30 is provided with glue injection holes 31.

[0081] The circuit board 30 is not only electrically connected to the charging interface 22, the main control board, etc., but also forms a glue storage space 2111 together with the sealing bracket 21, the charging interface 22, etc. by covering the installation opening 2113. The arrangement of the glue injection holes 31 allows waterproof glue to be injected between the circuit board 30 and the sealing bracket 21, further enhancing the waterproof performance of the personal care device 100. In some embodiments, two glue injection holes 31 are provided on the circuit board 30 and are distributed along the diagonal of the circuit board 30. In this way, it is convenient for glue injection and also convenient for arranging the layout of multiple electronic components on the circuit board 30.

[0082] Furthermore, the side wall of the glue storage groove 211 is provided with a boss 2114; the boss 2114 is spaced from the end face of the glue storage groove 211 away from the charging jack 11; the circuit board 30 is fixedly connected to the boss 2114, and the circuit board 30 is embedded in the glue storage groove 211.

[0083] In this embodiment, the circuit board 30 is fixed to the glue containing groove 211 through the boss 2114. The boss 2114, as the support structure of the circuit board 30, can effectively prevent the circuit board 30 from shifting or loosening under vibration or external force, thereby improving the structural stability and reliability of the entire product. Embedding the circuit board 30 in the glue containing groove 211 and fixing it with the help of the boss 2114, this layout makes full use of the limited space inside the personal care device 100. In this way, not only the volume of the product is reduced, but also the overall aesthetics is improved. At the same time, the boss 2114 and the end face of the glue containing groove 211 away from the charging jack 11 are spaced apart, providing sufficient space for the installation and fixation of the circuit board 30 and avoiding interference with other components.

[0084] In some embodiments, the boss 2114 is provided with a fixing hole 2115, and the circuit board 30 is provided with a through hole 32 at the position corresponding to the fixing hole 2115. The fastener 50 passes through the through hole 32 and the fixing hole 2115 in sequence, so that the circuit board 30 is fixedly connected to the boss 2114. The avoidance space 212 formed by the spaced arrangement of the boss 2114 and the end face of the glue containing groove 211 away from the charging jack 11 is used to accommodate the outer end of the fastener 50. In this way, not only can the stable connection between the circuit board 30 and the glue containing groove 211 be realized, but also the space in the glue containing groove 211 can be reasonably optimized. The boss 2114 also plays a role in enhancing the structural strength in this embodiment.

[0085] In one embodiment, the charging assembly 20 further includes a sealing ring 25a / 25b, and the sealing ring 25a / 25b is sleeved on the charging interface 22, and the outer wall of the sealing ring 25a / 25b abuts against the sealing bracket 21 or the decorative member 24.

[0086] The sealing ring 25a / 25b is usually made of an elastic material, such as rubber or silica gel.

[0087] In some embodiments, the sealing ring 25a forms a seal between the charging interface 22 and the sealing bracket 21. On the one hand, the sealing ring 25a can prevent moisture or dust from entering the glue containing space 2111 through the gap between the charging interface 22 and the sealing bracket 21. On the other hand, the sealing ring 25a can prevent the waterproof glue from flowing out of the glue containing space 2111 through the gap between the charging interface 22 and the sealing bracket 21.

[0088] In some embodiments, the sealing section 242 is located outside the sealing ring 25b; the sealing ring 25b is clamped between the sealing section 242 and the charging interface 22; a glue-containing space 2111 is formed by enclosing the outer peripheral surface of the charging interface 22, the inner wall surface of the sealing bracket 21, and the side surface of the decorative member 24 facing away from the charging jack 11. At this time, the sealing ring 25b seals the gap between the inner side surface of the decorative member 24 and the outer side surface of the charging interface 22. On the one hand, it prevents the outside from entering the interior of the personal care device 100 through this gap. On the other hand, it prevents the sealing glue in the glue-containing space 2111 from flowing out through this gap. In addition, in this embodiment, the glue-containing space 2111 makes full use of each component. For example, the bonding effect after the sealing glue is cured keeps the relative positions of the components stable. At the same time, the sealing glue can fill the small gaps that cannot be blocked by the sealing ring 25b and the seal 23.

[0089] In one embodiment, referring to Figure 2 , Figure 10 , the personal care device 100 further includes a battery and a mounting bracket 40 disposed in the main body case 10, the battery is disposed in the mounting bracket 40; the sealing bracket 21 is detachably connected to the mounting bracket 40 or the main body case.

[0090] The detachable connection includes but is not limited to snap connection, screw connection, and magnetic attraction connection. The detachable connection manner between the sealing bracket 21 and the mounting bracket 40 enables the user or the maintenance personnel to easily remove the sealing bracket 21 from the mounting bracket 40 or the main body case, so as to conveniently perform maintenance work such as cleaning, repairing, or replacing the inside of the razor. In this way, the maintainability of the product is improved, and the service life of the product is extended.

[0091] Further, referring to Figure 11 , a relief groove 41 is provided on one side of the mounting bracket 40 facing the charging jack 11, and the sealing bracket 21 is placed in the relief groove 41.

[0092] In this embodiment, the design of the relief groove 41 enables the sealing bracket 21 to be cleverly embedded inside the mounting bracket 40, thereby optimizing the internal layout of the razor. This layout not only saves space but also makes the overall structure more compact, which helps to reduce the volume and weight of the razor. The sealing bracket 21 is placed in the relief groove 41, and this structure helps to enhance the sealing performance of the razor in the area of the charging jack 11. The sealing bracket 21 serves as a barrier, which can effectively block external impurities such as moisture and dust from entering the interior of the razor and protect the battery and other electronic components from damage. At the same time, the relief groove 41 enables the mounting bracket 40 and the charging assembly 20 to be closely arranged, thereby simplifying the wiring and reducing the complexity of the wiring.

[0093] Further, referring to Figure 3 , Figure 11, the sealing bracket 21 includes a main body portion 213 and two connecting plates 214 respectively disposed on both sides of the main body portion 213; the main body portion 213 is disposed corresponding to the position of the charging jack 11; the connecting plates 214 are fixedly connected to the mounting bracket 40 or the main housing.

[0094] In this embodiment, the main body portion 213 and the connecting plates 214 in the sealing bracket 21 have clear functional divisions. Among them, the main body portion 213 is mainly used for charging and waterproofing, and the connecting plates 214 are used for connecting with the mounting bracket 40. This modular design can be adjusted according to the shapes of different mounting brackets 40 and main housings, improving the efficiency and functionality of the overall design. At the same time, by arranging the connecting plates 214 on both sides of the main body portion 213, the overall weight can be more evenly distributed. When subjected to external forces, the risk of the personal care device 100 tilting or flipping can be reduced. And the balanced weight distribution can provide a more comfortable holding feeling and reduce the fatigue of the user when using the handheld device.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
