BACKGROUND

[0002] Common household appliances, such as fans, warmers, etc., usually have a base at the bottom of the appliance body. Based on the stability of the base, the size of the base is generally designed to be larger. At present, with the rapid development of domestic e-commerce, people prefer to shop online, and goods are delivered to users' homes by express delivery.

[0003] To reduce storage and transportation costs, manufacturers often design the base to be separable from the appliance body. For example, the patent with the authorization announcement number "CN217685281U" discloses a detachable base for a warmer, which comprises a base and a warmer body mounted on the base. The base includes a main seat, a first widened seat and a second widened seat, and the bottom end of the main seat is provided with a skirt integrally formed thereon. The inner sides of the first widened seat and the second widened seat are provided with open slots, and the inner sides of the first widened seat are respectively fixedly connected with plugs. The inner sides of the second widened seat are provided with plug holes, and the inner walls of the plug holes are fixedly connected with rubber rings. The rubber rings are fixedly connected with magnetic rings, which can be magnetically attracted to the plugs. The top end of the main seat is provided with a connecting hole, and the bottom end of the warmer body is inserted into the connecting hole.

[0004] For example, the patent with the authorization announcement number "CN220911529U" discloses a multifunctional warmer that can be converted between mobile and wall-mounted modes. It consists of a heater and a main body. The heater is installed inside the main body. One end of the main body can detachably mount a base or a side panel.
