Patent Description:
Conventional household products, handheld electric devices such as electric irons, lint ball trimmers and hair brushes, etc., are usually larger in size, heavy in weight, and inconvenient to use and carry. And the handheld electric devices are powered by trailing cables, so that consumers' need for wirelessly using the handheld electric devices may not be met. In addition, in the handheld electric devices, a heating structure of the electric iron is heated by an electric heating tube, in which the electric heating tube needs to be pre-cast into an evaporator by die-casting technique. Such a complicated process is inconvenient to implement, and the scrap rate is high. Moreover, there are difficulties in producing a type of electric heating tube which is operated by using low-voltage direct current, owning to the fact that materials for producing such electric heating tubes are limited, generating a limitation on making the wireless handheld electric iron. Furthermore, a handle of the handheld electric device is often fixedly connected to its heating structure, that is, it is undetachable. Therefore, it is difficult to be carried and stored by a user. The handle is usually carried with a trailing cable, thus it is necessary to insert the plug into a socket for operation. It should be understood that the trailing cable makes its deployment defined within a limited distance and application scenarios.

On the other hand, conventional household products, such as electric irons, lint ball trimmers and hair brushes, etc., implement only one function, so it is impossible to transfer from one device to another to implement different functions. Thus, users have to purpose a various products for meet their demand for different functions.
