[0046] The utility model will be further described below in conjunction with the accompanying drawings.

[0047] See also Figure 1 and Figure 2 As shown, a charging stand 100 provided by an embodiment of the utility model includes: a support base 110, a bottom cover 120 and a charging assembly 140. The bottom cover 120 is sealed and connected to the top of the support base 110, and the bottom cover 120 and the support base 110 enclose a first cavity 132, and the charging assembly 140 is installed in the first cavity 132. The support base 110 is formed with a storage cavity 131 with an opening, which enables the nursing device 200 to be inserted into the storage cavity 131. The nursing device 200 placed in the storage cavity 131 can be wirelessly charged by the charging assembly 140 installed in the first cavity 132. Compared with charging the nursing device 200 through a plug-in structure, wireless charging does not require a charging interface or charging connector on the nursing device 200, which avoids the influence of the charging connector on the appearance of the nursing device 200, making the nursing device 200 more beautiful. The care device 200 may be a beauty instrument, or may be an electric toothbrush, an electric shaver, a dressing mirror, or other care device for personal hygiene.

[0048] The bottom cover 120 and the support base 110 also enclose a drainage channel 133 connected to the storage cavity 131. When charging, the accumulated water falling from the outer wall of the care device 200 into the storage cavity 131 can flow out of the care device charging stand 100 through the drainage channel 133. This prevents the accumulated water from always gathering in the storage cavity 131, and avoids the residual water vapor on the outer wall of the care device 200 after charging due to the accumulated water. This provides users with a better charging experience.

[0049] Since the care device 200 needs to be placed in the storage cavity 131 during charging, the storage cavity 131 can not only serve as a storage device, but also prevent water stains on the outside of the care device 200 from flowing to the outside of the storage cavity 131, thereby increasing the difficulty of water stains flowing into the first cavity 132 and improving the safety of the charging component 140.

[0050] In some implementations, the first cavity 132 is disposed around the drainage channel 133. In another implementation, the first cavity 132 is spaced apart from the drainage channel 133, for example, the drainage channel 133 is disposed on one side of the first cavity 132.

[0051] See also Figure 2 , Figure 3 as well as Figure 4 As shown, the first sleeve 1113 separates the drainage channel 133 from the first cavity 132. In this embodiment, the bottom cover 120 is further provided with a first sealing member 162 which is sealedly connected to the first sleeve 1113. The first sealing member 162 prevents the accumulated water in the drainage channel 133 from entering the first cavity 132.

[0052] Since the first cavity 132 surrounds the first sleeve 1113, compared with setting the first cavity 132 on one side of the first sleeve 1113, the first cavity 132 and the first sleeve 1113 can have a larger contact area without increasing the size of the first sleeve 1113. Due to the large contact area, the accumulated water in the drainage channel 133 during charging can significantly reduce the temperature of the first sleeve 1113 and the temperature in the first cavity 132, thereby preventing the wireless charging module from reducing the charging power due to excessive temperature, which is equivalent to water cooling.

[0053] Furthermore, the heat released by the charging assembly 140 during charging can accelerate the volatilization of the water in the drainage channel 133, thereby preventing water stains from remaining inside or at the bottom of the charging seat, thereby eliminating the need to clean the charging seat after charging.

[0054] In some implementations, such as Figure 2 and Figure 3 As shown, the charging component 140 includes a main board 142 and a charging coil 141, wherein the charging coil 141 surrounds the first sleeve 1113. When charging the care device 200 with water stains, the accumulated water flowing into the drainage channel 133 can be used to lower the temperature of the charging coil 141 to prevent the charging coil 141 from overheating.

[0055] refer to Figure 2 as well as Figure 5 As shown, in some implementations, the bottom cover 120 further includes a second sleeve 122, the first sleeve 1113 is inserted into the second sleeve 122, and the outer wall of the first sleeve 1113 is provided with a first seal 162, and the first seal 162 seals and connects the first sleeve 1113 to the second sleeve 122. The double-layer sleeve structure prevents the accumulated water in the exhaust channel from diffusing into the first cavity 132 to damage the charging component 140. The first seal 162 further reduces the accumulation of water in the exhaust channel from diffusing into the first cavity 132 to damage the charging component 140. Among them, the first seal 162 can be a sealing ring.

[0056] It is understandable that the outer diameter of the second sleeve 122 can be set smaller than the inner diameter of the first sleeve 1113. By inserting the second sleeve 122 into the first sleeve 1113, a double-layer sleeve structure is formed to reduce the risk of water leakage. Correspondingly, a first seal 162 is provided outside the second sleeve 122 to seal the gap between the first sleeve 1113 and the second sleeve 122.

[0057] Among them, the first sleeve 1113 can be a straight tube, or an inclined tube, a bent tube or a special-shaped tube, as long as the second sleeve 122 can be connected with the first sleeve 1113 to form a double-layer sleeve structure, and the specific structure of the first sleeve 1113 and the second sleeve 122 is not limited.

[0058] like Figure 5 As shown, in some implementations, the bottom cover 120 is provided with a plurality of first reinforcing ribs 123, the top surface height of the first reinforcing ribs 123 is higher than the bottom surface height of the first sleeve 1113, the first reinforcing ribs 123 are located in the first cavity 132, and the supporting assembly is supported on the first reinforcing ribs 123. In other words, the first reinforcing ribs 123 can not only improve the strength of the bottom cover 120, but also support the charging assembly 140, so that the bottom of the charging assembly 140 is higher than the bottom surface of the first sleeve 1113, even if a small amount of accumulated water flows into the first cavity 132, the charging assembly 140 can be prevented from contacting the accumulated water, thereby better ensuring the safe use of the charging assembly 140.

[0059] like Figure 5 As shown, in the present application, the bottom cover 120 includes a first plate 121, and four spaced first reinforcing ribs 123 are arranged on the first plate 121, of which two first reinforcing ribs 123 are arranged outside the second sleeve 122, which can reinforce the second sleeve 122 and support the central area of ​​the charging assembly 140. The first plate 121 is also provided with two first reinforcing ribs 123 spaced from the second sleeve 122, and the two first reinforcing ribs 123 are in a C-shaped structure, which can prevent the first plate 121 from deforming and can provide support for the outer side of the charging assembly 140. It can be understood that the intervals between the first reinforcing ribs 123 can be set larger to support the charging assembly 140 more stably.

[0060] like Figure 3 As shown, in some implementations, the charging stand 100 further includes a shell 150, which is sleeved outside the support base 110. That is, in this application, the support base 110 and the shell 150 are produced separately, and the two components are assembled only after both components are produced. A single support base 110 can be used to adapt to shells 150 of different shapes, adapting to more appearances.

[0061] like Figure 2As shown, in some implementations, the bottom of the shell 150 is sealed to the bottom cover 120, the top of the shell 150 is sealed to the support base 110, and the charging component 140 is installed in a closed space formed by the shell 150, the bottom cover 120 and the support base 110.

[0062] like Figure 2 As shown, in the present application, the first cavity 132 is formed by the shell 150, the bottom cover 120 and the support base 110, wherein the bottom cover 120 defines the lower surface of the first cavity 132, the support base 110 defines the upper surface and the inner side wall 151 of the first cavity 132, and the outer side wall 151 of the first cavity 132 is defined by the shell 150. Since the top of the shell 150 is sealed with the top of the support base 110, and the bottom of the shell 150 is sealed with the bottom cover 120, the first cavity 132 is relatively closed, which prevents the accumulated water from entering the first cavity 132 from the bottom or the top, and ensures the safety of the charging assembly 140.

[0063] In other implementations, a protrusion sealedly connected to the bottom cover 120 may be formed downwardly by the support base 110, so that a closed first cavity 132 is formed only by the support base 110 and the bottom cover 120, and the shell 150 is further covered outside the support base 110 to form an outer layer seal, thereby protecting the charging component 140 through two layers of seals.

[0064] See also Figure 2 and Figure 3 As shown, in the present application, the outer wall of the first cavity 132 is defined by the shell 150, and a socket 154 is provided on the side wall 151 of the shell 150, so that the charging cable 165 can pass through the shell 150 through the socket 154 and enter the first cavity 132 to connect with the charging component 140, which facilitates the charging cable 165 to charge the charging component 140. Among them, the main board 142 is integrated with a charging plug 1421, the charging plug 1421 is embedded in the socket 154, and the outer side of the charging plug interface is sealed with the shell 150 to prevent dust or liquid from entering the first cavity 132 through the gap between the charging plug 1421 and the socket 154. The charging cable 165 is detachably connected to the charging plug 1421. The charging cable 165 can be removed from the charging plug 1421 when traveling long distances to reduce the floor space of the charging stand 100 and facilitate carrying.

[0065] It is understandable that in other implementations, the charging connection cable 165 can also be directly integrated into the mainboard 142 by extending the end of the charging connection cable 165 away from the mainboard 142 through the socket 154 of the shell 150 and out of the first cavity 132 so that the charging connection cable 165 can be electrically connected to a power socket or related power supply equipment.

[0066] In order to prevent external dust or accumulated water from entering the first cavity 132 through the socket 154, in this embodiment, the housing 150 is formed with a first inwardly concave depression at the socket 154, and the concave direction of the first depression is set in the horizontal direction. By opening the socket 154 in the first depression, the housing 150 can be used to intercept dust and liquid above, preventing foreign objects from contacting the charging connector 1421 embedded in the socket 154.

[0067] See also Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, a first positioning structure 153 (visible Fig. 9 ), the support base 110 is provided with a second positioning structure 1114, one of the first positioning structure 153 and the second positioning structure 1114 is a positioning groove, the other of the first positioning structure 153 and the second positioning structure 1114 is a positioning block, and the first positioning structure 153 and the second positioning structure 1114 cooperate with each other so that the support base 110 is embedded in the shell 150.

[0068] In the present application, second positioning structures 1114 are provided on both sides of the support base 110, and the two second positioning structures 1114 are arranged at intervals, and two first positioning structures 153 are correspondingly arranged at intervals on the inner wall of the shell 150. Among them, the second positioning structure 1114 is a positioning block, and the first positioning structure 153 is a positioning groove. When the second positioning structure 1114 is inserted into the corresponding first positioning structure 153, the support base 110 and the shell 150 can be embedded, and the support base 110 can be prevented from rotating relative to the shell 150.

[0069] It is understandable that the structures of the first positioning structure 153 and the second positioning structure 1114 are various and not necessarily set to the columnar structure shown in the figure, but can also be set to an arc structure or a special-shaped structure, as long as the positioning between the housing 150 and the support base 110 can be achieved. Of course, the number of the second positioning structures 1114 is not necessarily two as shown in the figure, and a suitable number of second positioning structures 1114 can be selected and set according to the size of the support base 110.

[0070] Although the first positioning structure 153 is a positioning groove and the second positioning structure 1114 is a positioning block in the figure, in the actual production process, the second positioning structure 1114 can also be set as a positioning groove, and the corresponding first positioning structure 153 can be set as a positioning groove. It is also possible to set a plurality of first positioning structures 153 on the inner side of the shell 150, wherein a portion of the first positioning structures 153 are positioning grooves and another portion of the first positioning structures 153 are positioning blocks, and correspondingly set a plurality of second positioning structures 1114 on the support base 110, wherein a portion of the second positioning structures 1114 are positioning grooves and another portion of the second positioning structures 1114 are positioning blocks. During installation, the second positioning structure 1114 in the form of a positioning block is inserted into the corresponding first positioning structure 153 in the form of a positioning groove, so that the other first positioning structures 153 cooperate with the corresponding second positioning structure 1114 to achieve the embedding of the support base 110 and the shell 150. See. Figure 2 and Fig.12 As shown, in some implementations, a first positioning groove 155 extending circumferentially along the storage cavity 131 is formed at the top of the shell 150; the support base 110 has a sealing protrusion 1123 located at the top thereof, and the sealing protrusion 1123 includes a first sealing body 11231 and an elastic rib 11232. The shape of the first sealing body 11231 is adapted to the concave cross-section of the first positioning groove 155. When the sealing protrusion 1123 is inserted into the first positioning groove 155, the elastic rib 11232 is compressed and deformed to seal the gap between the first sealing body 11231 and the first positioning groove 155.

[0071] That is, the cross-sectional area of ​​the sealing protrusion 1123 is at least larger than the inner cross-sectional area of ​​the first positioning groove 155 by the cross-sectional area of ​​the elastic rib 11232. When the sealing protrusion 1123 is inserted into the first positioning groove 155, at least the elastic rib 11232 will be compressed and deformed, thereby improving the sealing effect between the sealing protrusion 1123 and the first positioning groove 155.

[0072] refer to Figures 6 to 8 As shown, in this embodiment, the support base 110 includes a support frame 111 and an elastic buffer 112, wherein the top of the buffer 112 is formed with the above-mentioned sealing protrusion 1123. That is, the first sealing body 11231 and the elastic rib 11232 in the sealing protrusion 1123 are both elastic. Figure 7 and Fig.11As shown, the elastic rib 11232 is an annular structure, and the elastic rib 11232 is arranged on the top of the first sealing body 11231. When the sealing protrusion 1123 is inserted into the first positioning groove 155, the elastic rib 11232 is squeezed by the side wall 151 of the first positioning groove 155 before the first sealing body 11231 and deforms. When the side wall 151 of the first sealing body 11231 fits the inner wall of the first positioning groove 155, the first sealing body 11231 is also compressed, so that the outer wall of the sealing protrusion 1123 fits tightly with the inner wall of the first positioning groove 155. There is an excellent sealing performance between the top of the housing 150 and the top of the support base 110.

[0073] It is understandable that the sealing protrusion 1123 can also be formed on the top of the support base 110 without the buffer member 112 .

[0074] In the present application, the molding process of the buffer component 112 can be adjusted so that the process ribs are formed at the sealing protrusion 1123, which can reduce the process ribs in other places, reduce the installation difficulty of other positions of the buffer component 112, and achieve a sealing effect with the top of the shell 150.

[0075] See also Fig.12 As shown, the housing 150 includes a side wall 151 and a first limiting protrusion 152. The side wall 151 is sleeved outside the support base 110. The first limiting protrusion 152 is higher than the support base 110. The first limiting protrusion 152 is connected to the side wall 151 to form a first positioning groove 155.

[0076] The bottom of the sealing protrusion 1123 is connected with a second limiting protrusion 1124, and the second limiting protrusion 1124 contacts the first limiting protrusion 152. By forming the first limiting protrusion 152 of the first positioning groove 155 and contacting the first limiting protrusion 152 at the bottom of the sealing protrusion 1123, excessive upward squeezing of the sealing protrusion 1123 can be avoided, the elastic deformation of the sealing protrusion 1123 is reduced, and the elastic life of the sealing protrusion 1123 can be reduced. When the support base 110 is inserted and installed multiple times, the sealing protrusion 1123 can still be guaranteed to have good elasticity. It should be noted that the diameter of the storage cavity 131 is smallest at the second limiting protrusion 1124, and the diameter of the storage cavity 131 at the second limiting protrusion 1124 is equal to the maximum outer diameter of the part of the care device 200 inserted into the storage cavity 131. In other words, the axis positioning of the care device 200 can also be achieved through the first limiting protrusion 152 to prevent the care device 200 from shaking in the storage cavity 131.

[0077] like Figure 2 and Figure 3As shown, in some implementations, the bottom cover 120 is detachably mounted on the bottom of the housing 150 through the connecting piece 164, and when the bottom cover 120 is connected to the housing 150, it will press the support base 110 upward, so that the sealing protrusion 1123 on the top of the support base 110 is always embedded in the first positioning groove 155, so as to achieve a sealed connection between the support base 110 and the housing 150. Since the first limiting protrusion 152 is provided on the housing 150, it can prevent the support base 110 from being too close to the top and can provide a downward extrusion force for the support base 110, so that the bottom cover 120 and the housing 150 are closely fitted.

[0078] In some embodiments, a first sealing groove 124 extending circumferentially is provided on the bottom cover 120, and a second sealing member 163 is installed in the first sealing groove 124. When the bottom cover 120 is connected to the housing 150 through the connecting member 164, the second sealing member 163 seals and connects the housing 150 to the bottom cover 120. This prevents the accumulated water discharged from the drainage channel 133 from flowing into the first cavity 132 through the gap between the bottom cover 120 and the housing 150, and can better protect the charging assembly 140 in the first cavity 132. Specifically, a mounting boss 126 is provided on the bottom cover 120, and a countersunk hole 1261 is formed at the bottom of the mounting boss 126. The connecting member 164 passes through the countersunk hole 1261 and is connected to the housing 150.

[0079] refer to Figure 3 As shown, the charging stand 100 also includes a third sealing member 168, and further reference is made to Figure 5 as well as Fig. 9 As shown, a mounting boss 126 is formed on the upper surface of the bottom cover 120, and a third sealing member 168 is covered on the mounting boss 126. When the bottom cover 120 is connected to the housing 150, the mounting boss 126 is inserted into the second sealing groove 156 formed in the housing 150, and the sealing connection at the mounting boss 126 is achieved through the third sealing member 168. Fig. 9 As shown, the housing 150 is formed with four second sealing grooves 156 , which can seal the four mounting bosses 126 of the bottom cover 120 .

[0080] like Figure 3 As shown, in some implementations, the connecting member 164 is a bolt or a screw, and by screwing the connecting member 164, the bottom cover 120 can be gradually pressed upward onto the housing 150, and the supporting base 110 can be pressed upward by the connecting force between the connecting member 164 and the housing 150, and the first positioning groove 155 can be sealed while the bottom cover 120 is connected. It can be understood that the connecting member 164 can also be a rivet or a clamping member, as long as the bottom cover 120 can be pressed upward onto the housing 150.

[0081] like Figure 2 and Figure 5As shown, a support column 125 is also provided on the first plate body 121 of the bottom cover 120; the support column 125 is located in the first cavity 132 and the top is supported on the bottom of the support base 110. The support column 125 can be used to transmit the extrusion force generated by the connecting member 164 to the support base 110, so that the support base 110 can be tightly inserted into the first positioning groove 155 upward to achieve a sealed connection between the shell 150 and the support base 110. It can be understood that the number of the support columns 125 can be two, and the number of the support columns 125 can also be increased according to the mass of the support base 110. Of course, the support columns 125 can also be set as a ring structure to improve the bearing capacity of the base.

[0082] See also Fig.12 As shown, in some implementations, the first limiting protrusion 152 is provided with a conical hole extending along the axial direction of the support base, the axis of the conical hole and the opening axis of the storage cavity are in the same straight line, the conical hole has a small mouth end and a large mouth end, the inner diameter of the small mouth end is smaller than the inner diameter of the large mouth end; the inner diameter of the small mouth end of the conical hole is greater than or equal to the inner diameter of the opening of the storage cavity 131, and the small mouth end is connected to the opening of the storage cavity 131.

[0083] That is to say, the tapered hole is a structure with a large opening at one end and a small opening at the other end, and the end with the small opening of the tapered hole is connected to the opening of the receiving cavity 131. When inserting the nursing device 200 into the opening of the receiving cavity 131, the nursing device 200 needs to pass through the large end and the small end of the tapered hole in sequence before it can be inserted into the opening of the receiving cavity 131. The inner diameter of the large end of the tapered hole is larger than the inner diameter of the small end, and the inner diameter of the small end is larger than or equal to the inner diameter of the opening of the receiving cavity 131, that is, the inner diameter of the large end is larger than the inner diameter of the opening of the receiving cavity 131. Obviously, it is less difficult to insert the nursing device 200 into the large end than to directly insert it into the opening of the receiving cavity 131.

[0084] In addition, due to the tapered hole structure, after the nursing device 200 is inserted, the side wall of the tapered hole can be used to gradually guide the nursing device 200 to the small end, thereby guiding the nursing device 200 to the opening of the storage cavity 131. Compared with directly inserting the nursing device 200 into the opening of the storage cavity 131, the difficulty is lower. That is, the difficulty of inserting the nursing device 200 into the opening of the storage cavity 131 is reduced.

[0085] That is to say, the first limiting protrusion 152 can not only limit the installation height of the support base 110 by limiting the height of the second limiting protrusion 1124 , but also can guide the nursing device 200 to be inserted into the storage cavity 131 .

[0086] See also Figure 4As shown, the support base 110 includes a support frame 111, which is connected to the bottom cover 120. The support frame 111 is connected to a buffer 112 for contacting the nursing device 200, and the buffer 112 is made of a soft material. The buffer 112 made of a soft material can achieve a certain vibration reduction effect, thereby preventing the nursing device 200 from directly colliding with the support frame 111 and being damaged when the nursing device 200 is inserted into the storage cavity 131, and can better protect the nursing device 200.

[0087] In some implementations, the support frame 111 is made of hard plastic, and the buffer 112 is made of soft silicone. It is not difficult to imagine that in other implementations, the support frame 111 can also be made of engineering plastic or metal material to provide stronger support. Similarly, the buffer 112 can also be made of rubber material, or other soft materials with buffering properties.

[0088] like Figure 4 As shown, in some implementations, the support frame 111 includes a first plate portion 1111 and a first barrel portion 1112 connected to each other, the first plate portion 1111 is connected to the first barrel portion 1112 and forms a positioning cavity, the buffer 112 is installed in the positioning cavity, the buffer 112 includes a second plate portion 1121 and a second barrel portion 1122, the second plate portion 1121 is closely fitted with the first plate portion 1111, the second barrel portion 1122 is closely fitted with the inner wall of the first barrel portion 1112, the second plate portion 1121 is connected to the second barrel portion 1122 and forms a storage cavity 131. That is, when the nursing device 200 is inserted into the storage cavity 131, the buffer 112 separates the nursing device 200 from the support frame 111, thereby achieving full protection of the part of the nursing device 200 inserted into the storage cavity 131.

[0089] Among them, reference Figure 4 As shown, in some implementations, a plurality of anti-detachment through holes 11121 are provided on the first barrel 1112, and the first barrel 1112 and the second barrel 1122 are connected by a conical rivet 167, wherein the diameter of the large end of the conical rivet 167 is larger than the inner diameter of the anti-detachment through hole 11121 on the first barrel 1112, and the first barrel 1112 is sandwiched between the large end of the conical rivet 167 and the second barrel 1122. The second barrel 1122 can be pulled tight and fitted to the first barrel 1112 by the conical rivet 167, thereby avoiding the shaking of the second barrel 1122 and providing a more stable storage space for the nursing device 200. It is understandable that the first barrel 1112 and the second barrel 1122 can also be connected by a clamping structure or directly connected by bonding, and are not limited to being connected by the conical rivet 167.

[0090] refer to Figure 4 , Figure 6 as well as Figure 8 As shown, a plurality of anti-slip grooves 11122 are provided at the top of the first barrel 1112, and a corresponding anti-slip protrusion 11221 is provided at the top of the second barrel 1122. When the buffer 112 is connected to the support frame 111, the anti-slip protrusion 11221 can be inserted into the anti-slip groove 11122 to prevent the top of the second barrel 1122 from being separated from the first barrel 1112, thereby ensuring that the first barrel 1112 is tightly connected to the second barrel 1122. It is understandable that the anti-slip groove 11122 can also be provided on the second barrel 1122, and the anti-slip protrusion 11221 can be provided on the first barrel 1112, that is, the setting positions of the anti-slip protrusion 11221 and the anti-slip groove 11122 are not particularly limited, as long as the first barrel 1112 and the second barrel 1122 can be tightly connected.

[0091] It can be understood that in order to allow the accumulated water in the storage cavity 131 to flow smoothly into the first sleeve 1113 of the support frame 111, a drainage hole is opened on the second plate portion 1121 of the buffer 112, and the drainage hole can be set to a conical hole structure to guide the nearby accumulated water into the first sleeve 1113.

[0092] refer to Figure 4 , Figure 6 as well as Figure 8 As shown, a first mounting hole 11111 is provided on the first plate portion 1111, and a first conical protrusion 11211 protruding downward is provided at the bottom of the second plate portion 1121, and the large end of the first conical protrusion 11211 is downward and passes through the first mounting hole 11111, and the outer diameter of the large end of the first conical protrusion 11211 is larger than the inner diameter of the first mounting hole 11111, and the first plate portion 1111 and the second plate portion 1121 are tightly connected by the cooperation between the first conical protrusion 11211 and the first mounting hole 11111.

[0093] refer to Figure 1 and Figure 2 As shown, the opening of the storage cavity 131 is set upward, and the depth of the storage cavity 131 is greater than or equal to 1 / 3 of the length of the nursing device 200. By setting the depth of the storage cavity 131 to be deeper, the nursing device 200 can be better stored and prevented from tipping over after the nursing device 200 is inserted into the storage cavity 131.

[0094] It is understandable that the opening of the storage cavity 131 does not necessarily have to be arranged upward, but can also be arranged inclined upward.

[0095] like Figure 1 , Figure 8 as well as Fig. 9As shown, in some implementations, the housing 150 is a trumpet-shaped structure that is small at the top and large at the bottom, and the thickness of the bottom is greater than the thickness of the top. The housing 150 configured in this way has a lower center of gravity and higher stability. When the nursing device 200 is inserted into the storage cavity 131, the center of gravity of the entire device formed by the nursing device 200 and the charging stand 100 is lowered, thereby preventing the nursing device 200 from tipping over due to an excessively high center of gravity.

[0096] See also Figure 2 As shown, in some implementations, a third limiting protrusion 1221 is provided at the bottom of the second sleeve 122, and the third limiting protrusion 1221 forms a hole structure with an inner diameter smaller than the inner diameter of the first seal 162. By providing the third limiting protrusion 1221, the first seal 162 can be prevented from moving downward, thereby ensuring the sealing effect of the first seal 162.

[0097] See also Figure 2 as well as Figure 4 As shown, in some implementations, the support frame 111 is further provided with a limiting ring 1115 at the bottom of the first plate portion 1111, and the limiting ring 1115 is framed outside the first sleeve 1113, and the limiting ring 1115 and the first sleeve 1113 form a receiving groove, and the top of the charging coil 141 of the charging assembly 140 is received in the receiving groove. By providing the limiting ring 1115 on the support frame 111 to limit the charging coil 141, not only can the displacement of the charging coil 141 be avoided, but also the limiting ring 1115 can be used to improve the strength of the first plate portion 1111. Compared with adding additional parts to limit the charging coil 141, the number of parts is reduced and the cost is reduced.

[0098] In some implementations, a foot pad 161 is also connected to the bottom of the bottom cover 120. The foot pad 161 can be used to lift the bottom cover 120 to prevent the bottom cover 120 from being immersed in the accumulated water flowing out of the drainage channel 133. The foot pad 161 can also increase the friction of the charging stand to achieve an anti-slip effect.

[0099] On the other hand, the present application also provides a personal care device, which includes the care device charging stand 100 provided above, and also includes a care device 200, which can be detachably inserted into the storage cavity 131 of the support base 110, so as to achieve the storage effect of the care device 200. The personal care device can be a beauty device for beauty, or a toothbrush for cleaning teeth, a dental care device such as a water flosser, or a hair care device such as a razor and a hair clipper.

[0100] When the nursing device 200 needs to be charged, the charging assembly 140 disposed in the first cavity 132 can be used to wirelessly charge the nursing device 200. Since there is a drainage channel 133 connected to the storage cavity 131, and the drainage channel 133 and the storage cavity 131 are not connected to the first cavity, the nursing device 200 can be directly inserted into the storage cavity 131 after washing, and the water stains on the nursing device 200 will flow to the storage cavity 131 and then be discharged from the drainage channel 133, thereby avoiding the formation of water accumulation in the storage cavity 131. There is no need to consider water immersion failure during the charging process and the cleaning process, which is very convenient to use.

[0101] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
