The provision of the push-to-talk button 302 facilitates user operation and improves operational convenience. Compared to related art, there is no need to cycle through function buttons to select the desired function. Furthermore, the partitioned arrangement of the push-to-talk button area 102 and the conventional button area 103 makes it easier for the user to intuitively select the desired function, thus facilitating user use.

[0048] Specifically, in one embodiment, the functions corresponding to the one-touch buttons 302 include quick cooking, fine cooking, porridge, soup, hot rice, and steaming. Each one-touch button 302 corresponds to a function, and the one-touch button area 102 is provided with a quick cooking one-touch button 302, a fine cooking one-touch button 302, a porridge one-touch button 302, a soup one-touch button 302, a hot rice one-touch button 302, and a steaming one-touch button 302. For example, when a user needs to cook rice quickly, they only need to touch or press the quick cooking one-touch button 302, and the cooking appliance can enter the quick cooking mode.

[0049] Specifically in one embodiment, the push-to-talk button 302 and the regular button 303 are both touch spring buttons, whose working principle is based on capacitive touch sensing technology, and triggers the switch action by detecting the capacitance change caused by finger touch.

[0118] 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.

[0119] In one embodiment, the upper surface of the face cover 1 is flat.

[0120] 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.

[0121] In one embodiment, Figure 14 As shown, the cover assembly also includes an inner cover 6, and a groove 207 and one of the ribs 601 are provided on the side of the electrical box 2 facing away from the surface cover 1, and the other of the groove 207 and the rib 601 is provided on the side of the inner cover 6 facing the electrical box 2. The groove 207 is adapted to the shape of the rib 601 and has an assembly gap.

[0122] In this embodiment, 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. 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.

[0123] Specifically, in one embodiment, the groove 207 is provided on a side of the electrical box 2 facing away from the surface cover 1 , and the rib 601 is provided on a side of the inner cover 6 facing the electrical box 2 .

[0124] The assembly process of the cover assembly provided in this embodiment is as follows: 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 seal is sealed with glue.

[0125] 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.

[0126] In this device with a cover assembly, when a user touches or presses the trigger portion of the push-to-talk button 302, the corresponding push-to-talk button 302 on the circuit board 3 senses the user's operation and controls the cooking appliance to perform the corresponding function. The provision of the push-to-talk button 302 facilitates user operation and improves operational convenience. Compared with related technologies, there is no need to cycle through function buttons to select the desired function. Furthermore, the partitioned arrangement of the push-to-talk button area 102 and the conventional button area 103 makes it easier for the user to intuitively select the desired function, thus facilitating user use.

[0127] Specifically in one embodiment, the device having the cover assembly is a cooking utensil, such as an electric rice cooker, a pressure cooker, etc.

[0128] 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.
