The charging structure comprises a contact thimble 20, an electrical connection component 30 and a magnetic component 40.
The contact thimble 20 is arranged on the chassis 10 and penetrating to a lower surface of the chassis 10, wherein the contact thimble 20 is connected to the circuit.
The electrical connection component 30 comprises a connector 31 and a wire 32 for connecting the connector 31, wherein the wire 32 is used for accessing a power source, and the connector 31 is electrically connected with the thimble when it is abutted with the contact thimble 20;
A magnetic component comprises a first magnetic member 41 disposed on a chassis 10 and a second magnetic member 42 disposed on a connector 31, wherein the first magnetic member 41 and the second magnetic member 42 are attracted to each other to abut the connector 31 with a contact thimble 20;
wherein, a horizontal projection of the chassis 10 covers a horizontal projection of the connector 31.
When the charging structure provided by the present embodiment is used, the connector 31 is close to a lower surface of the chassis 10 so as to attract the connector 31 to the lower surface of the chassis 10 through the mutual attraction of the first magnetic member 41 and the second magnetic member 42, and the connector 31 is abutted with the contact thimble 20 so as to realize electrical connection between the connector 31 and the contact thimble 20. The operation is very convenient.
In addition, the charging structure is located under the chassis 10 so that the charging structure is prevented from protruding on the side position of the home furnishing small household electrical appliance, and the horizontal projection of the connector 31 is covered by that of the chassis 10. Seen from a top view, the connector 31 is hidden and seen from the side view the connector 31 is also not easy to be found, thereby reducing the impact of the charging structure on the overall appearance of the home furnishing small household electrical appliance.
It should be further noted that in terms of the connection between the existing male connector 31 and the female connector 31, in order to ensure the firm connection between the male connector 31 and the female connector 31, the male connector 31 and the female connector 31 are usually connected in a nested manner. The male connector 31 is large in size. If the connection of the male connector 31 and the female connector 31 is directly transferred to a lower side of the chassis 10, it occupies large vertical space. The charging structure provided by the present solution may be electrically connected by abutting the contact thimble 20 with the connector 31, and the chassis 10 and the connector 31 are connected by the magnetic component 40, so that the size of the connector 31 may be flat and miniaturized, thereby effectively reducing the vertical space occupied, further conducive to its own hiding as well as reducing is the impact on the overall appearance of the home furnishing small household electrical appliance.
It should be further explained that the present solution is different from a charging structure of a kettle. A kettle comprises a kettle body, a tray and a charging structure. The charging structure of the kettle comprises a connector disposed on the kettle body, a metal protrusion disposed on the tray and a wire for connecting the metal protrusion. The kettle body and the tray are provided with a corresponding card position respectively. When the kettle body is clamped onto the tray, the connector is abutted with the metal protrusion to achieve electrical connection between the kettle body and the wire. In this connection, the kettle body is connected to the tray by the weight of the kettle body. The present solution adopts a magnetic connection, which is different from this solution and is not a simple replacement. Specifically, if the chassis 10 is pressed against the connector 31 by the weight of the main body of the household appliance, since the main body of the household appliance and the chassis 10 are not perspective, in order to achieve the aligned clamping of the chassis 10 and the connector 31, the size of the connector 31 is required to be set to be equal to or larger than that of the chassis 10, which is contrary to the purpose of hiding the connector 31 as much as possible in the present solution. In the present solution, the alignment is realized mainly through mutual attraction of the first magnetic member 41 and the second magnetic member 42. Thus, the charging structure of the present solution is different from a charging structure of a kettle and is not a simple replacement.
