[0127] In one embodiment, Figure 3 and Figure 4 As shown, the cover 1 is provided with one of the sealing groove 112 and the rib 206, the electrical box 2 is provided with the other of the sealing groove 112 and the rib 206, the sealing ring 5 is installed in the sealing groove 112 and partially extends out of the sealing groove 112, and the rib 206 is against the sealing ring 5.

[0128] In this embodiment, the setting of the sealing groove 112 facilitates fixing the position of the sealing ring 5, and the rib 206 abuts against the sealing ring 5. After the electrical box 2 and the cover 1 are assembled, the sealing ring 5 is squeezed to ensure a sealed connection between the cover 1 and the electrical box 2.

[0129] Specifically in one embodiment, the height of the rib 206 is 0.4-0.6 mm.

[0130] Specifically in one embodiment, the sealing groove 112 is provided on the surface cover 1 , and the rib 206 is provided on the electrical box 2 .

[0131] In one embodiment, the width of the sealing ring 5 is greater than or equal to the width of the sealing groove 112 .

[0132] In this embodiment, since the width of the sealing ring 5 is greater than or equal to the width of the sealing groove 112 , it can be ensured that the sealing ring 5 is sealed in the sealing groove 112 .

[0133] Specifically in one embodiment, the diameter of the cross section of the sealing ring 5 is 3.6-4.2 mm, the width of the sealing groove 112 is 3-3.6 mm, and the depth of the sealing groove 112 is 3-3.3 mm.

[0134] In one embodiment, the thickness of the sealing ring 5 is greater than the depth of the sealing groove 112 .

[0135] In this embodiment, when the sealing ring 5 is installed in the sealing groove 112, a portion of the sealing ring 5 is exposed. After the electrical box 2 and the surface cover 1 are fixed together, the electrical box 2 compresses the sealing ring so that the electrical box 2 and the surface cover 1 are assembled without leaving any gaps, thereby preventing water vapor from entering the interior of the electrical box and damaging the components on the circuit board 3.

[0136] In one embodiment, the upper surface of the face cover 1 is flat.

[0137] In this embodiment, since the upper surface of the face cover 1 is flat, when liquid overflows from the steam outlet on the face cover 1, it can be prevented from flowing toward the facial mask 4 and then entering the interior of the facial mask 4.

[0138] The assembly process of the cover assembly provided in this embodiment is as follows:

[0139] First, the circuit board 3 and the electrical box 2 are positioned through the first positioning hole 305 and the first positioning column 201. Then, the circuit board 3 is pressed so that the circuit board 3 is fixed by the first clip 202 and supported by the support rib 208. At this time, the circuit board 3 and the electrical box 2 are assembled into one piece. Then, the limiting column 109 on the cover 1 is passed through the first through-hole 306 on the circuit board 3 and inserted into the limiting hole 203 in the electrical box 2. The first buckle 204 on the electrical box 2 is buckled with the second buckle 110 on the cover 1 to pre-fix the electrical box 2. Then, the screw is passed through the screw hole 205 on the electrical box 2 and screwed into the screw column 111 of the cover 1 to achieve a fixed connection between the cover 1 and the electrical box 2. After the assembly is completed, the surrounding rib 206 of the electrical box 2 compresses the sealing ring 5 in the sealing groove 112 on the cover 1, making the assembly more compact. After the circuit board 3 and the electrical box 2 are assembled, the wires are led out through the outlet hole, and then the glue is applied to seal. After the electrical box 2 is fixedly connected to the surface cover 1, the inner cover 6 is fixedly connected to the surface cover 1 through the peripheral buckles.

[0140] According to an embodiment of the present invention, on the other hand, a device having a cover assembly is provided, including the cover assembly provided in the above embodiment.

[0141] In the device with a cover assembly, the electrical box 2 is located in the space formed by the surface cover 1 and the inner cover 6, which can prevent water from entering the electrical box 2. By providing an assembly gap between the groove 207 and the rib 601, assembly problems caused by errors in the production of parts can be avoided. The arrangement of the groove 207 and the rib 601 can support the electrical box 2 when the connection between the surface cover 1 and the electrical box 2 fails.

[0142] Specifically in one embodiment, the device having the cover assembly is a cooking utensil, such as an electric rice cooker, a pressure cooker, etc.

[0143] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by this application.
