[0051] A battery device for a mobile home appliance includes a housing 11, a power supply assembly 14 located within the housing 11, a control board 13 located below the power supply assembly 14, and a mounting plate 15 located below the housing 11. The housing 11 includes an upper housing 111 and a lower housing 112. The lower housing 112 is provided with a strip-shaped hole 1122. A first magnetic member 131 is provided on both sides of the control board 13 near the lower housing 112.

When the shell 11 is to be installed on the mounting plate 15, since the first oblique conical surface 1125 of the lower shell 112 is adapted to the second oblique conical surface 152 of the mounting plate 15, the first oblique conical surface 1125 of the lower shell 112 can be fitted with the second oblique conical surface 152 from any direction. The second oblique conical surface 152 guides the lower shell 11 to be quickly installed in the mounting plate 15, and the first magnetic attraction component 131 and the second magnetic attraction component are quickly attracted to each other, thereby preventing the battery device from being separated from the mobile appliance.

[0052] Working principle: Example 1:

[0053] When installing the battery device, first, install the lower shell 112 on the mounting plate 15 of the mobile appliance, and the first plane 1124 of the lower shell 112 fits with the top of the mounting plate 15. When the first magnetic part 131 and the second magnetic part are attracted to each other, the battery device is fixed to the mobile appliance by magnetic attraction, and the limiting protrusion 153 of the mounting plate 15 extends into the second placement groove 1123 and is connected to the connecting part 133. The power supply component 14 supplies power to the mobile appliance through the connecting part 133 on the control board 13. Furthermore, when the battery device is installed on the mobile appliance, the mobile appliance is started, and the battery device supplies power to the mobile appliance through the connecting part 133, thereby facilitating the movement of the mobile appliance and getting rid of the constraints of wires. At the same time, the battery device can be quickly installed on the mobile appliance or quickly removed from the mobile appliance, making it more convenient to use. Example 2:

[0054] When installing the battery device, first, when installing the shell 11 on the mobile appliance, contact the lower shell 112 with the mounting plate 15, loosen the shell 11, and the shell 11 moves down according to its own weight. When the first magnetic component 131 and the second magnetic component are attracted to each other, the limiting protrusion 153 of the mounting plate 15 is opposite to the second placement groove 1123 of the lower shell 112, and the battery device cannot be installed on the mobile appliance. The battery device needs to be repositioned. After the battery device is repositioned, the first magnetic component 131 and the second magnetic component are attracted to each other, thereby fixing the battery device on the mobile appliance. When removing the battery device from the mobile appliance, you only need to pull the battery device out from the top of the mobile appliance. The battery device can be quickly installed on the mobile appliance or the battery device can be quickly removed from the mobile appliance, which is more convenient to use. Example 3:

[0055] When the battery device is installed on the mobile appliance, first, the first inclined conical surface 1125 of the lower shell 112 of the battery device is placed on the second inclined conical surface 152 of the mounting plate 15. Since the first inclined conical surface 1125 is adapted to the second inclined conical surface 152, when the battery device is released, the second inclined conical surface 152 guides the battery device to move into the mounting plate 15. Since the first inclined conical surface 1125 and the second inclined conical surface 152 are adapted to each other, the first inclined conical surface 1125 of the lower shell 112 can be fitted with the second inclined conical surface 152 from any direction. The second inclined conical surface 152 guides the lower shell 11 to be quickly installed in the mounting plate 15, and the first magnetic attraction part 131 is quickly attracted to the second magnetic attraction part, thereby preventing the battery device from being separated from the mobile appliance. When removing the battery device from the mobile appliance, it is only necessary to pull the battery device out from the top of the mobile appliance. The battery device can be quickly installed on the mobile appliance or the battery device can be quickly removed from the mobile appliance, which is more convenient to use.

[0056] The battery device of the mobile appliance of this preferred embodiment is provided with a second magnetic component inside the mobile appliance. The battery device is connected to the mobile appliance, and the first magnetic component and the second magnetic component are attracted to each other, so that the battery device can be quickly connected and fixed to the mobile appliance.

[0057] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
