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

[0030] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides a wall-mounted charging device 10, including: a wall-mounted body 100, a transmitting end coil 300 and a first magnetic attraction component 400, and may also include a second magnetic attraction component 200, for example.

[0031] The wall-mounted body 100 may, for example, have a wall-mounted side 11 and a charging side 12, and the wall-mounted side 11 is arranged opposite to the charging side 12. The wall-mounted side 11 is used to be fixed on a wall, a desk, a dressing table, etc., and the charging side 12 is used to connect a device to be charged, such as an oral cleaning device, an electric shaver, a hair dryer, etc. The second magnetic component 200, the transmitting end coil 300 and the first magnetic component 400 are all arranged on the wall-mounted body 100. The second magnetic component 200 and the transmitting end coil 300 are arranged on the wall-mounted body 100 near the charging side 12, and the first magnetic component 400 is arranged on the wall-mounted body 100 near the wall-mounted side 11. The second magnetic component 200 and the transmitting end coil 300 are arranged correspondingly to realize wireless charging after magnetic connection with the device to be charged. The first magnetic component 400 and the transmitting end coil 300 are staggered in the first direction, and the first direction is the direction along the wall-mounted side 11 toward the charging side 12. By staggering the first magnetic component 400 and the transmitting end coil 300 in the first direction, the influence of the first magnetic component 400 on the transmitting end coil 300 can be reduced, so that the wall-mounted charging device 10 can be wall-mounted through the first magnetic component 400 while ensuring that the transmitting end coil 300 can reduce heat generation and improve charging efficiency when charging the device to be charged.

[0032] In some implementations of this embodiment, the transmitting end coil 300 and the second magnetic member 200 may be, for example, arranged on the outer surface of the wall-mounted body 100, that is, the transmitting end coil 300 and the second magnetic member 200 are arranged on the side of the charging side 12 of the wall-mounted body 100 away from the wall-mounted side 11, and may be connected to the outer surface of the wall-mounted body 100 by, for example, pasting, riveting, etc.; the first magnetic member 400 may also be, for example, arranged on the outer surface of the wall-mounted body 100, and may be, for example, arranged on the side of the wall-mounted side 11 of the wall-mounted body 100 away from the charging side 12, and may be connected to the outer surface of the wall-mounted body 100 by, for example, pasting, riveting, etc. In other implementations of this embodiment, the transmitting end coil 300, the first magnetic member 400 and the second magnetic member 200 may be, for example, arranged inside the wall-mounted body 100. Of course, the specific positions of the transmitting end coil 300, the first magnetic member 400 and the second magnetic member 200 in the wall-mounted body 100 may be arranged according to actual needs, and this embodiment is not limited thereto.

[0033] In one implementation of this embodiment, the first magnetic member 400 has a first projection on the wall-mounted body 100 along the first direction, and the transmitting end coil 300 has a second projection on the wall-mounted body 100 along the first direction, and the first projection may be, for example, located at the periphery of the second projection, or the second projection is located at the periphery of the first projection. Thus, the first magnetic member 400 and the transmitting end coil 300 are staggered in the first direction, which can reduce the influence of the first magnetic member 400 on the transmitting end coil 300.

[0034] Furthermore, the second magnetic member 200 and the first magnetic member 400 at least partially overlap in the first direction, which can reduce the influence of the second magnetic member 200 and the first magnetic member 400 on the transmitting end coil 300. The second magnetic member 200 and the first magnetic member 400 can be magnets or components that can be attracted by magnets, such as iron sheets. Specifically, in one implementation of this embodiment, the second magnetic member 200 can be, for example, a circular magnet and is arranged in the middle position, the transmitting end coil 300 is arranged around the second magnetic member 200, the transmitting end coil 300 can be, for example, an annular structure, and the second magnetic member 200 is located in the inner circle of the annular structure. The first magnetic member 400 can also be, for example, a magnet, and the first magnetic member 400 is arranged corresponding to the second magnetic member 200. The first magnetic member 400 can also be, for example, a circular magnet, and the first magnetic member 400 has the same shape and size as the second magnetic member 200, and is arranged correspondingly in the first direction. By making the first magnetic member 400 and the second magnetic member 200 the same shape and size, and correspondingly arranging them in the first direction, the influence of the first magnetic member 400 on the coil can be further reduced. Of course, the diameter of the first magnetic member 400 may also be, for example, greater than the diameter of the second magnetic member 200; the thickness of the first magnetic member 400 in the first direction may also be greater than the thickness of the second magnetic member 200, and the present embodiment is not limited thereto, so that the magnetic attraction strength of the first magnetic member 400 can be improved to improve the suspension stability. In another implementation of the present embodiment, the first magnetic member 400 and the second magnetic member 200 may both be, for example, a plurality of magnets, the plurality of magnets are arranged in an annular structure, and the magnetism of two adjacent magnets on the side facing the charging side 12 is opposite. Furthermore, a positioning iron sheet may also be provided on the side of the plurality of magnets facing the wall-mounted side 11, so as to facilitate the arrangement of the plurality of magnets into an annular structure.

[0035] In another implementation of this embodiment, the second magnetic member 200 may be, for example, an annular magnet or a plurality of magnets arranged in an annular structure, and the transmitting end coil 300 is located in the inner circle of the annular structure of the second magnetic member 200, that is, the second magnetic member 200 is arranged around the transmitting end coil 300. The first magnetic member 400 may also be, for example, a magnet, and the first magnetic member 400 is arranged corresponding to the second magnetic member 200. The first magnetic member 400 may also be, for example, an annular magnet or a plurality of magnets arranged in an annular structure, and the first magnetic member 400 has the same shape and size as the second magnetic member 200, and is arranged correspondingly in the first direction; of course, the diameter of the first magnetic member 400 may also be, for example, greater than the diameter of the second magnetic member 200; and the thickness of the first magnetic member 400 in the first direction may also be greater than the thickness of the second magnetic member 200, and this embodiment is not limited thereto.

[0036] In one implementation of the present embodiment, the second magnetic member 200 has a second projection on the wall-mounted body 100 along the first direction, and the first projection may, for example, cover the second projection. The first magnetic member 400 and the second magnetic member 200 may, for example, have the same shape and are correspondingly arranged in the first direction, which can further reduce the influence of the first magnetic member 400 on the coil. Specifically, the diameter of the first magnetic member 400 may also, for example, be greater than the diameter of the second magnetic member 200, thereby increasing the magnetic attraction strength of the first magnetic member 400 without increasing the thickness of the first magnetic member 400, reducing the occupation of the internal space of the wall-mounted body 100, and reducing the volume of the wall-mounted body 100 while improving the suspension stability.

[0037] See also Figure 2 and Figure 3 , the wall-mounted charging device 10 may, for example, also include a magnetic isolation structure, which is arranged between the transmitting end coil 300 and the first magnetic attraction member 400. Specifically, the magnetic isolation structure may be, for example, a first magnetic isolation member 500, or the magnetic isolation structure may be a nanocrystalline magnetic isolation sheet 600, or the magnetic isolation structure may also include, for example, a first magnetic isolation member 500 and a nanocrystalline magnetic isolation sheet 600, and the first magnetic isolation member 500 and the nanocrystalline magnetic isolation sheet 600 are stacked. The first magnetic isolation member 500 may be a hard magnetic isolation member, such as a ferrite magnetic isolation member sintered at high temperature. By arranging the magnetic isolation structure between the transmitting end coil 300 and the first magnetic attraction member 400, the influence of the first magnetic attraction member 400 on the transmitting end coil 300 can be further reduced to improve the charging efficiency. By setting the nanocrystalline magnetic isolation sheet 600, the magnetic isolation structure can be made thinner while ensuring the magnetic isolation effect, which can improve the magnetic isolation effect while reducing the occupation of the internal space of the wall-mounted main body 100, and further reduce the volume of the wall-mounted main body 100. The wall-mounted body 100 may, for example, also be provided with a charging circuit board 700 and a charging interface 800. The charging circuit board 700 is electrically connected to the charging interface 800 and is electrically connected to the charging interface 800 via a charging cable for charging. Of course, it can also be connected to the charging circuit board 700 via a charging cable for charging.

One side of the hanging fixture 110 is used to be fixed to a wall, a dressing table or a cabinet, for example, by 3M glue, rivets, etc. The charging body 120 may, for example, include a first shell 122 and a second shell 123, the first shell 122 and the second shell 123 are covered to form the charging body 120, the second magnetic member 200, the transmitting end coil 300 and the first magnetic member 400 are arranged on the charging body 120, and the first magnetic member 400 is magnetically connected to the hanging fixture 110.

The first hook portion 111 may be, for example, a suspension protrusion, and the second hook portion 121 may be, for example, a suspension groove. Of course, this embodiment is not limited to this. Further, the suspension fixture 110 may be, for example, an iron material, and the first magnetic member 400 is magnetically connected to the suspension fixture 110; the suspension fixture 110 may also be provided with a magnet corresponding to the first magnetic member 400, so that the first magnetic member 400 is magnetically connected to the suspension fixture 110.

[0039] See also Figure 5 A hanging portion 125 is provided on the side of the charging body 120 away from the hanging fixture 110, and the hanging portion 125 is used to hang the device to be charged. Specifically, two hanging members 124 are further provided on the side of the charging body 120 away from the hanging fixture 110, and the hanging portion 125 is formed between the two hanging members 124. The device to be charged is hung on the wall-mounted body 100 by being clamped on the hanging portion 125 for wireless charging.

[0042] See also Figure 8, a receiving end coil 23 is arranged on the cleaning device body 20, and the receiving end coil 23 is electromagnetically inductively connected to the transmitting end coil 300 for wireless charging. The cleaning device body 20 may, for example, also be provided with a third magnetic attraction member 22, a circuit board 25, and a second magnetic isolation member 24. The receiving end coil 23, the third magnetic attraction member 22, and the second magnetic isolation member 24 may, for example, be arranged on the outer surface of the cleaning device body 20 close to the wall-mounted charging device 10, or may, for example, be arranged on a side of the cleaning device body 20 close to the wall-mounted charging device 10.

The second magnetic isolation member 24 can be, for example, a nanocrystalline magnetic isolation sheet, which can improve the magnetic isolation effect while reducing the occupation of the internal space of the cleaning device body 20.
