referring to the perspective view of the back of the sealing cover shown in fig. 10, a first mounting through hole 211 is formed on the first mounting surface 261, a second mounting through hole 212 is formed on the second mounting surface 262, and both ends of the hinge shaft 207 respectively pass through the first mounting through hole 211 and the second mounting through hole 212;

the cover body mounting cavity is further provided with a first baffle 221 and a second baffle 222, when the cover body panel 252 is arranged on the back surface of the cover body shell 251 and closes the cover body mounting opening, the first baffle 211 is opposite to the first mounting through hole 211, the second baffle 222 is opposite to the second mounting through hole 212, and the first baffle 221 and the second baffle 222 respectively limit two ends of the hinge shaft 207 to prevent the hinge shaft 207 from coming out of the first mounting through hole 211 and the second mounting through hole 212.

In a specific implementation, the first flap 221 and the second flap 222 may be disposed on the cover panel or the cover shell, in an embodiment of the present invention, the first flap 221 may be disposed on the cover shell, and the second flap may be disposed on the cover panel, by this implementation, when the hinge shaft 207 is installed, a section of the hinge shaft 207 first protrudes into the first installation through hole 211 by an excessive amount, and then the other end of the hinge shaft extends from the second installation through hole 212 and abuts against the second flap 222, and the second flap 222 also plays a role of installation limiting, so that it is possible to avoid interference (interference of the hinge shaft 207 with the first flap 221) when the hinge shaft 207 protrudes into the first installation through hole 211 by an excessive length, which may result in interference when the cover panel and the cover shell are matched.

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.

In conclusion, the invention provides the electric steamer, most structural parts of the electric steamer can be processed and supported in an injection molding mode, the electric steamer is convenient to process and assemble, and the manufacturing cost is low; the sealing cover and the box body both adopt a double-layer box body structure, so that heat can be effectively insulated, and the use safety is good; the sealing performance of the sealing cover is good, and the cooking efficiency of food can be ensured; due to the structural arrangement of the partition plate, the food cooking efficiency can be ensured, the continuous working time of the electric steam box can be taken into account, and the electric steam box has good practicability; the working mode and the using mode of the electric steam box can be well used by office users, and the electric steam box has the characteristics of small volume, convenience in use, safety in use and the like.

The above detailed description is provided for an electric steamer provided by the embodiment of the present invention, and the principle and the embodiment 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 a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
