Specifically, the cover panel 252 is disposed on the back surface of the cover housing 251 based on a snap mechanism and closes the cover mounting opening. The locking mechanism comprises a locking piece 254 and a locking piece 255 which are matched with each other, and the cover body panel 252 and the cover body shell 251 are locked based on a plurality of groups of locking mechanisms. Meanwhile, as the buckling mechanism can only be arranged at the edge position, in order to ensure the strength of the middle parts of the cover body panel and the cover body shell, a plurality of thimbles 256 are also arranged on the cover body panel, and the thimbles 256 are used for enhancing the bonding strength (pressure resistance) of the cover body panel and the cover body shell.

In addition, the lid adopts the combination form of lid panel and lid shell, and lid panel and lid shell are after the installation finishes, can not direct contact (middle part position, non-marginal position) between lid panel and the lid shell, and at this moment, the lid can be fine play thermal-insulated effect, has reduced the risk that the user scalded.

In specific implementation, the hinge shaft is firstly installed on the cover body panel, then the cover body panel is installed on the cover body shell, and after the sealing cover is assembled, the sealing cover is hinged to the hinge connecting part (hinge hole) based on the hinge shaft, so that the assembly of the sealing cover is realized. When using, place on the plane through opening sealed lid and with the face of placing of sealed lid, can make and place the cavity and can place comparatively steady confession food and tray, have good convenience for use, can avoid simultaneously food and the water on the tableware to drip to the desktop on, clean and manage more conveniently.

The above detailed description is made on an electric steamer provided by the embodiment of the present invention, and the principle and the implementation of the present invention are explained by applying a specific example, and the description of the above embodiment is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
