Description

Technical Field

[0001] The utility model relates to the technical field of personal care, in particular to a charging seat and care equipment. Background Art

[0002] In order to facilitate the use of beauty instruments, the main body of the beauty instrument and the charging stand are currently designed separately, which can not only conveniently charge the main body of the beauty instrument through the charging stand, but also avoid the restriction of the charging stand on the main body of the beauty instrument during normal use, making it more convenient to use. In order to stably charge the beauty instrument, a storage cavity will be set in the charging stand, and the main body of the beauty instrument can be inserted into the storage cavity. When the beauty instrument is inserted into the charging stand for charging, the beauty instrument can also be stored in the charging stand.

[0003] In the related art, a wireless charging component is integrated in the charging stand, and the beauty instrument body is charged through the wireless charging component. Due to the use of wireless charging technology, it is avoided to open a charging interface on the beauty instrument body, which greatly improves the appearance of the beauty instrument.

[0004] However, when the charging stand is open for use, foreign objects often fall into the storage cavity. If the foreign objects fall into the storage cavity, the foreign objects will be sandwiched between the wireless charging component and the beauty instrument body, thereby affecting the distance between the wireless charging component and the beauty instrument body, and reducing the charging efficiency of the wireless charging component.

[0040] The present utility model will be further described below in conjunction with the accompanying drawings.

[0041] Wireless charging uses the principle of electromagnetic wave induction for charging, and the principle is similar to that of a transformer. By generating a changing magnetic field through the wireless charging component 120, a current is generated in the coil of the device to be charged, thereby realizing the charging of the device to be charged. Since the principle of wireless charging is electromagnetic induction charging, it is necessary to avoid the presence of ferromagnetic conductors such as iron and steel between the charging device and the charging coil. If there are ferromagnetic conductors such as iron and steel between the charging device and the charging coil, during the charging process of the wireless charging device to the device to be charged, the ferromagnetic conductor will generate an induced current in the changing magnetic field, resulting in a decrease in the charging power of the device to be charged. Moreover, the ferromagnetic conductor may heat up due to the induced current, thereby damaging the charging device or even causing an accident.

[0042] That is to say, in order to enable the normal charging of the nursing device 200 inserted into the storage cavity 111, it is necessary to avoid the presence of foreign objects in the storage cavity 111. To solve the above problems, the present utility model provides a charging base 100.

[0043] See Figures 1 to 4 As shown, a charging base 100 provided by an embodiment of the present utility model includes: a support base 110, a wireless charging component 120 (see Figure 3 ), and a foreign object suction cover 130.

[0044] Among them, the wireless charging component 120 is connected to the support base 110, and the wireless charging component 120 can realize wireless charging of the nursing device 200 inserted into the storage cavity 111, avoiding the setting of a charging interface or a charging connector on the nursing device 200, which can greatly improve the appearance of the nursing device 200.

[0045] See Figures 5 to 7 As shown, the foreign object suction cover 130 is installed at the opening 112 of the support base 110. In the illustration, the foreign object suction cover 130 is rotatably connected to the opening 112 of the support base 110. By rotating the foreign object suction cover 130, the opening 112 of the support base 110 can be closed or opened. After the care device 200 is taken out of the storage cavity 111, the opening 112 can be closed by the foreign object suction cover 130, and the foreign object suction cover 130 can prevent foreign objects from falling into the storage cavity 111.

[0046] When the wireless charging component 120 is needed to charge the care device 200, the opening 112 of the support base 110 is opened by rotating the foreign object suction cover 130, so that the care device 200 can be inserted into the storage cavity 111, enabling the care device 200 to cooperate with the wireless charging component 120 at the bottom of the storage cavity 111, and the wireless charging component 120 charges the care device 200 wirelessly.

[0047] The foreign object suction cover 130 can suck up foreign objects that have fallen into the storage cavity, preventing the foreign objects in the storage cavity from affecting the charging efficiency of wireless charging.

[0048] In some implementation manners, the foreign object suction cover 130 has magnetism. When the foreign object suction cover 130 closes the opening 112, the magnetic force of the foreign object suction cover 130 can generate a magnetic field in the storage cavity 111, thereby sucking up the magnetically conductive foreign objects that have fallen to the bottom of the storage cavity 111, and preventing the magnetically conductive foreign objects that have fallen into the storage cavity 111 from interfering with the normal operation of the wireless charging component 120. Here, the magnetically conductive foreign objects refer to foreign objects such as iron and steel that have a relatively high magnetic permeability and can be adsorbed by a magnet.

[0049] In some other implementation manners, an air extraction device can also be provided on the foreign object suction cover 130 to suck out foreign objects in the storage cavity by air extraction, or a telescopic suction cup structure can be provided at the foreign object suction cover 130. By extending the suction cup downward to the bottom of the storage cavity, the foreign object is adsorbed on the suction cup. Then, through the contraction of the telescopic structure, the foreign object adsorbed on the suction cup is taken out of the storage cavity.

[0050] See Figure 3 And Figure 4 As shown, the wireless charging component 120 is arranged at the bottom of the storage cavity 111, and the wireless charging component 120 is embedded in the support base 110. The material of the support base 110 can be selected from plastics, aluminum alloys, or other materials that will not be adsorbed by the foreign object suction cover 130.

[0051] In some implementations, the magnetic field strength of the foreign object suction cover 130 is adjustable. By increasing the magnetic field strength, the foreign object suction cover 130 can adsorb larger magnetically conductive foreign objects. After the foreign object suction cover 130 is removed from the opening 112 of the support base 110, the magnetic field strength of the foreign object suction cover 130 can be lowered to facilitate cleaning of the magnetically conductive foreign objects adsorbed on the foreign object suction cover 130. Compared with the foreign object suction cover 130 with a fixed magnetic field strength, since the magnetic field strength of the foreign object suction cover 130 of the present application is adjustable, the foreign object can be easily sucked up when the foreign object suction cover 130 is required to adsorb magnetically conductive foreign objects. Moreover, when cleaning the magnetically adsorbed foreign objects on the foreign object suction cover 130, the magnetic field strength can be reduced.

[0052] In some implementations, the foreign object suction cover 130 includes a first magnet 131 and a second magnet 132. The second magnet 132 can move relative to the first magnet 131 so that the foreign object suction cover 130 has a strong magnetic state and a weak magnetic state.

[0053] It can be understood that when the second magnet 132 moves relative to the first magnet 131, the magnetic field generated by the second magnet 132 will move synchronously relative to the magnetic field generated by the first magnet 131, so that the combined magnetic field of the two magnets changes, and thus the foreign object suction cover 130 has different magnetic capabilities.

[0054] That is to say, the present application provides a structure for adjusting the magnetic field strength of the foreign object suction cover 130 by relative movement. Compared with an electromagnet that increases the magnetic field strength by increasing the current, the problems of heat generation and safety caused by large current are avoided, and the applicable range is wider.

[0055] In some implementations, the second magnet 132 can move relative to the first magnet 131 until the two magnetic poles of the first magnet 131 are respectively close to the like-named magnetic poles of the second magnet 132, so that the foreign object suction cover 130 is in a strong magnetic state. The corresponding approach of the like-named magnetic poles here means that the south magnetic pole of the first magnet 131 is close to the south magnetic pole of the second magnet 132, and the north magnetic pole of the first magnet 131 is close to the north magnetic pole of the second magnet 132.

[0056] Moreover, the second magnet 132 can also move relative to the first magnet 131 until the two magnetic poles of the first magnet 131 are respectively close to the unlike-named magnetic poles of the second magnet 132, so that the foreign object suction cover 130 is in a weak magnetic state. The corresponding approach of the unlike-named magnetic poles here means that the south magnetic pole of the first magnet 131 is close to the north magnetic pole of the second magnet 132, and the north magnetic pole of the first magnet 131 is close to the south magnetic pole of the second magnet 132.

[0057] It can be understood that when the like poles are close to each other, the magnetic field directions generated by the two magnets are generally the same, making the combined magnetic field of the two magnetic fields greater than the magnetic field generated by a single magnet, and almost achieving the effect of adding the magnetic field intensities of the two magnets.

[0058] When the unlike poles are close to each other, the magnetic field directions generated by the two magnets are generally opposite, making the combined magnetic field of the two magnets smaller than the magnetic field generated by a single magnet, and causing partial cancellation of the two magnetic fields.

[0059] That is to say, since the second magnet 132 can be moved relative to the first magnet 131 so that the like poles are correspondingly close to each other, it is possible to greatly increase the magnetic field intensity of the combined magnetic field without increasing the magnetic field intensity of a single magnet. At the same time, since the second magnet 132 can be moved relative to the first magnet 131 so that the unlike magnets are correspondingly close to each other, it is possible to greatly reduce the magnetic field intensity of the combined magnetic field without weakening the magnetic field intensity of a single magnet. Without adjusting the magnetic field intensity of a single magnet, the adjustment range of the combined magnetic field is expanded.

[0060] Bring the like poles or unlike poles of the first magnet 131 and the second magnet 132 close to each other.

[0061] The foreign object suction cover 130 is in a strong magnetic state and can adsorb larger foreign objects.

[0062] When the foreign object suction cover 130 is in a weak magnetic state, the magnetic suction force can be reduced to facilitate the removal of the magnetic foreign object adsorbed on the foreign object suction cover 130, realizing the cleaning of the foreign object suction cover 130.

[0063] Among them, the second magnet 132 can be adjusted to overlap with the first magnet 131 and the poles are correspondingly close to each other by rotation, realizing the adjustment of the magnetic field intensity of the foreign object suction cover 130.

[0064] It can be understood that in other implementation manners, the position and angle of the second magnet 132 can also be adjusted by a combination of movement and rotation, so as to adjust the magnetic field intensity of the foreign object suction cover 130.

[0065] See Figure 1 、 Figure 8 and Figure 9 As shown, in some implementation manners, the foreign object suction cover 130 further includes a first cover body 133 and a second cover body 134. The second cover body 134 can rotate relative to the first cover body 133, and the rotation axis between the first cover body 133 and the second cover body 134 is the first rotation axis. It should be noted that the first rotation axis here is only for facilitating the description of the direction, and there may not be an actual rotation axis structure in practice.

[0066] The first magnet 131 is fixed to the first cover 133, and the second magnet 132 is fixed to the second cover 134. The first rotating shaft vertically passes through the centers of the first magnet 131 and the second magnet 132. That is to say, both the first magnet 131 and the second magnet 132 are vertically arranged relative to the first rotating shaft, and the first rotating shaft passes through the center of the first magnet 131 and the center of the second magnet 132.

[0067] Since the first magnet 131 is fixed to the first cover 133 and the second magnet 132 is fixed to the second cover 134, when the second cover 134 is rotated relative to the first cover 133, the second magnet 132 fixed to the second cover 134 will rotate relative to the first magnet 131 fixed to the first cover 133. Thereby, the included angle between the first magnet 131 and the second magnet 132 is adjusted.

[0068] Since the first rotating shaft passes through the center of the second magnet 132, when the second cover 134 is rotated, the second magnet 132 actually rotates around its center. And the second rotating shaft passes through the center of the second magnet 132. That is to say, the centers of the first magnet 131 and the second magnet 132 will always be on a straight line (the first rotating shaft), and the first magnet 131 and the second magnet 132 can be conveniently overlapped by rotation.

[0069] Compared with other methods for adjusting the position of the second magnet 132, in this application, the second magnet 132 can be adjusted by rotating the second cover 134, which is relatively simple. And by controlling the positions of the first magnet 131 and the second magnet 132, the overlapping of the two magnets can be conveniently achieved.

[0070] It can be understood that magnet structures other than the first magnet 131 and the second magnet 132 can be provided in the foreign object suction cover 130 to achieve more magnetic field combinations and more magnetic field adjustment modes.

[0071] In this application, the second cover 134 is directly buckled on the first cover 133 and rotatably connected to the first cover 133, so that the second cover 134 can be rotated by manual screwing. The operation is relatively convenient, and no additional driving structure needs to be provided, and the occupied volume is small.

[0072] In this application, a first limiting groove 13322 is provided in the first cover 133, and the first magnet 131 is installed in the first limiting groove 13322 to prevent the first magnet 131 from rotating relative to the first cover 133. In some other implementation manners, the first magnet 131 can also be limited by setting a limiting protrusion.

[0073] Similarly, a second limiting groove 1341 is formed in the second cover body 134, and the second magnet 132 is installed in the second limiting groove 1341 to prevent the second magnet 132 from rotating relative to the second cover body 134.

[0074] To fix the first magnet 131 in the first cover body 133, the first magnet 131 can be connected to the first cover body 133 by bonding, or the first magnet 131 can be embedded in the first cover body 133 by interference fit to prevent the first magnet 131 from moving relative to the first cover body 133.

[0075] It should be noted that in this implementation, the first rotating shaft is perpendicular to the first magnet 131 and the second magnet 132. By rotating the second cover body 134 to adjust the angle of the second magnet 132, actually, the first magnet 131 can also be fixed on the first cover body 133, and the second magnet 132 can be directly connected to the first cover body 133, omitting the structure of the second cover body 134. Or the second magnet 132 can be fixedly connected to the second cover body 134, and the first cover body 133 can be connected to the second cover body 134, omitting the structure of the first cover body 133.

[0076] In addition, although the above provides a structure for setting a limiting groove for magnet installation, in other implementations, a shell structure can also be directly formed by injection molding outside the magnet to realize the fixed connection between the magnet and the cover body.

[0077] See Figure 9 、 Figure 10 and Figure 11 As shown, the first cover body 133 includes a connecting cover plate 1331 and a clamping sleeve 1332. The connecting cover plate 1331 is fixedly connected to the clamping sleeve 1332, and the first magnet 131 is fixed to the connecting cover plate 1331 of the first cover body 133. A first anti - detachment buckle 13321 is provided at the end of the clamping sleeve 1332, and a second anti - detachment buckle 1342 is provided at the corresponding position of the second cover body 134. The second cover body 134 is partially inserted into the clamping sleeve 1332, and the second anti - detachment buckle 1342 is buckled with the first anti - detachment buckle 13321 to prevent the first cover body 133 from separating from the second cover body 134.

[0078] In some implementations, the clamping sleeve 1332 and the connecting cover plate 1331 are connected by ultrasonic welding or hot plate welding processes, or the clamping sleeve 1332 and the connecting cover plate 1331 can be integrally formed.

[0079] Among them, at least one of the first anti - detachment buckle 13321 and the second anti - detachment buckle 1342 is a ring structure, so that when the second cover body 134 rotates relative to the first cover body 133, the first anti - detachment buckle 13321 can always cooperate with the second anti - detachment buckle 1342 to realize the anti - detachment connection between the first cover body 133 and the second cover body 134.

[0080] The connection strength between the first cover 133 and the second cover 134 is improved by the anti-loosening buckle structure, which can avoid the separation of the first cover 133 and the second cover 134 caused by the repulsion of the magnets.

[0081] See Figure 11 and Figure 12 As shown, in order to facilitate the confirmation of the magnetic state of the foreign object suction cover 130, magnetic pole marks 135 are provided on both the first cover 133 and the second cover 134. When the south magnetic pole mark 135 on the first cover 133 corresponds to the south magnetic pole mark 135 on the second cover 134, it indicates that the south magnetic pole of the first magnet 131 is relatively close to the south magnetic pole of the second magnet 132, that is, the foreign object suction cover 130 is in a strong magnetic state.

[0082] When the south magnetic pole mark 135 on the first cover 133 corresponds to the north magnetic pole mark 135 on the second cover 134, it indicates that the south magnetic pole of the first magnet 131 is relatively close to the north magnetic pole of the second magnet 132, that is, the foreign object suction cover 130 is in a weak magnetic state.

[0083] See Figure 11 and Figure 12 As shown, in some implementation manners, both the first magnet 131 and the second magnet 132 are bar magnets. The first magnet 131 is disposed in a first plane, and the second magnet 132 is disposed in a second plane. Both the first plane and the second plane are perpendicular to the first rotating shaft, and the second magnet 132 can rotate around the first rotating shaft. Thus, by only rotating, different magnetic poles of the second magnet 132 can be brought close to the magnetic poles of the first magnet 131 to switch the magnetic field strength of the foreign object suction cover 130.

[0084] See Figure 6 and Figure 9 As shown, in some implementation manners, when the foreign object suction cover 130 closes the opening 112, the first rotating shaft is disposed along the extending direction of the receiving cavity 111. Since the second magnet 132 rotates around the first rotating shaft, by controlling the extending direction of the first rotating shaft, it can be ensured that the dimension of the second magnet 132 in the extending direction of the receiving cavity 111 is always equal to the thickness of the second magnet 132, which is beneficial to reducing the thickness of the foreign object suction cover 130 in the extending direction of the receiving cavity 111 and making the shape more beautiful.

[0085] In some implementation manners, the direction of the first rotating shaft can also be controlled to be disposed along the extending direction of the receiving cavity 111 when the foreign object suction cover 130 closes the opening 112. When the second magnet 132 rotates around the first rotating shaft, the maximum dimension in the extending direction of the receiving cavity 111 is the length of the second magnet 132. As a result, the thickness of the foreign object suction cover 130 in the extending direction of the receiving cavity 111 is too thick, which is not beneficial to the shape of the foreign object suction cover 130.

[0086] In some implementations, the first cover 133 and the second cover 134 are in damping fit at their rotational connection. Through the damping fit of the two covers, the second cover 134 can be prevented from rotating when the second cover 134 is not screwed, so that the foreign object suction cover 130 can continue to maintain the adjusted magnetic field strength.

[0087] To prevent the damping fit between the first cover 133 and the second cover 134 from making it difficult to rotate the second cover 134, in some implementations, a cross-shaped adjustment groove 1343 is provided on the second cover 134. The second cover 134 can be rotated by inserting a cross screwdriver into the adjustment groove 1343 and then rotating the cross screwdriver. It can be understood that the adjustment groove 1343 can also be set as an internal hexagonal groove corresponding to the size of a hexagonal wrench, and the second cover 134 can be rotated by inserting the hexagonal wrench into the adjustment groove 1343 and then turning the hexagonal wrench.

[0088] Or anti-slip patterns are provided on the outer contours of the first cover 133 and the second cover 134 to prevent slipping of the hand when manually rotating the second cover 134 and reduce the difficulty of rotating the second cover 134.

[0089] Specifically, in the present application, a sealing ring 137 is provided between the first cover 133 and the second cover 134, and the first cover 133 and the second cover 134 are in interference fit through the sealing ring 137. There is a large frictional resistance between the first cover 133 and the second cover 134.

[0090] See Figure 9 As shown, in some implementations, the first cover 133 and the second cover 134 enclose a receiving cavity, the first magnet 131 and the second magnet 132 are both received in the receiving cavity 111, and the first cover 133 and the second cover 134 are hermetically connected.

[0091] By receiving the first magnet 131 and the second magnet 132 in the receiving cavity and sealing the first cover 133 and the second cover 134. It is avoided that the magnetic foreign objects adsorbed by the foreign object suction cover 130 are sucked into the receiving cavity and directly contact the first magnet 131 and the second magnet 132. The internal space of the receiving cavity can be relatively clean, reducing the cleaning work of the first magnet 131 and the second magnet 132. And it can prevent water vapor and the like from entering the receiving cavity and corroding the first magnet 131 and the second magnet 132.

[0092] See Figure 9As shown, both the first magnet 131 and the second magnet 132 are permanent magnets. Compared with electromagnets, permanent magnets have a stable magnetic field and do not require additional supporting power supplies. This is beneficial for the miniaturization of the foreign object suction cover 130 and results in lower costs. Moreover, compared with electromagnets, the magnetic attraction function is achieved through permanent magnets. Since there is no current, the energy consumption is small and there is no heat generation, making it more convenient to use.

[0093] Specifically, both the first magnet 131 and the second magnet 132 are made of the permanent magnetic material neodymium iron boron (Nd-Fe-B). Permanent magnets made of neodymium iron boron material have excellent properties such as high remanence, high coercivity, and high magnetic energy product, and can maintain magnetism for a long time to achieve the adsorption of ferromagnetic foreign objects.

[0094] Of course, the permanent magnet can also be a permanent magnet made of materials such as ferrite, samarium cobalt, or alnico.

[0095] See Figure 5 and Figure 9 As shown, in some implementation manners, the foreign object suction cover 130 is provided with a first rotating structure 136, and the support base 110 is provided with a second rotating structure 113. The first rotating structure 136 is rotatably connected to the second rotating structure 113, and the first rotating structure 136 and the second rotating structure 113 are in damping cooperation.

[0096] With the first rotating structure 136 and the second rotating structure 113 in damping cooperation, the foreign object suction cover 130 can be held at a specific angle when the foreign object suction cover 130 is flipped, which facilitates magnetically attracting devices such as mobile phones and tablets to the foreign object suction cover 130. So that when relevant personnel charge the nursing device 200 using the support base 110, the foreign object suction cover 130 can be used as a mobile phone stand.

[0097] In some implementation manners, the first rotating structure 136 provided on the foreign object suction cover 130 is a hole structure, and the second rotating structure 113 on the support base 110 is a shaft structure. By inserting the second rotating structure 113 into the first rotating structure 136, the rotational connection between the first rotating structure 136 and the second rotating structure 113 is achieved. In other implementation manners, the first rotating structure 136 on the foreign object suction cover 130 can be set as a shaft structure, and the second rotating structure 113 on the support base 110 can be set as a hole structure. By inserting the first rotating structure 136 into the second rotating structure 113, the rotational connection between the foreign object suction cover 130 and the support base 110 is achieved.

[0098] Of course, the first rotating structure 136 and the second rotating structure 113 can also both be set as shaft structures, and a hole structure independent of the foreign object suction cover 130 and the support base 110 is provided for the first rotating structure 136 and the second rotating structure 113 to be inserted therein to achieve the rotational connection between the foreign object suction cover 130 and the support base 110.

[0099] Among them, the shaft structures in the first rotating structure 136 and the second rotating structure 113 can select damping rotating shaft structures to achieve the damping cooperation between the first rotating structure 136 and the second rotating structure 113. There are various current implementation methods for the damping shaft structure, which will not be described in detail in the specification. As long as the damping cooperation between the first rotating structure 136 and the second rotating structure 113 can be achieved.

[0100] In a second aspect, the present utility model also provides a nursing device, which includes: a nursing device 200 and the above charging base 100. Among them, the nursing device 200 is detachably inserted into the opening 112 of the charging base 100.

[0101] The nursing device here can be a beauty device for nursing the skin, an electric toothbrush for cleaning teeth, or an electric hair clipper for trimming hair.

[0102] When using the nursing device 200, the nursing device 200 can be taken out from the storage cavity 111 of the charging base 100, and the nursing device 200 is used to perform nursing work on the user. By closing the opening 112 of the charging base 100 with the foreign object suction cover 130, foreign objects are prevented from falling into the storage cavity 111 of the charging base 100, and the magnetic foreign objects in the storage cavity 111 can be sucked up by the foreign object suction cover 130 to prevent the magnetic foreign objects from affecting the wireless charging work of the wireless charging component 120.

[0103] When charging the nursing device 200, the opening 112 of the charging base 100 can be opened by flipping the foreign object suction cover 130, so that the nursing device 200 can be inserted into the opening 112 of the storage cavity 111, and the nursing device 200 is wirelessly charged by the wireless charging component 120 in the charging base 100.

[0104] See Figures 2 to 4 As shown, the nursing device 200 includes a fuselage 210 and a nursing head 220. The nursing head 220 is connected to the fuselage 210 to care for the skin of the user. A control board 230 is provided on or inside the fuselage 210, and a battery 240 and a wireless charging receiving component 250 are installed at the bottom of the fuselage 210.

[0105] When the fuselage 210 is inserted into the storage cavity 111, the wireless charging receiving component 250 in the fuselage 210 corresponds to the wireless charging component 120 in the charging base 100, and the battery 240 of the nursing device 200 is charged by the combined action of the wireless charging component 120 and the wireless charging receiving board.

[0106] Since the nursing device 200 uses wireless charging technology to achieve charging, there is no need to set a charging interface or connector on the nursing device 200, which can not only improve the consistency of the appearance of the nursing device 200, but also improve the waterproof performance of the nursing device 200.

[0107] Although the present invention has been described with reference to the preferred embodiments, various modifications can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
