[0029] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0030] Example 1

[0031] Please refer to Figure 5-Figure 8 As a specific embodiment, the utility model provides a cover body, the technical solution of which is as follows: comprising an upper cover 1, the upper cover is provided with an exhaust port 10, the exhaust port 10 is provided with an inner cover assembly 2, the inner cover assembly comprising:

[0032] The cylinder 21 is detachably mounted on the exhaust port 10 , and its outer wall is sealed with the inner wall of the exhaust port 10 ;

[0033] A first plate 22 is provided at the first end of the cylinder 21 , and a plurality of exhaust holes 220 are evenly distributed on the first plate 22 ;

[0034] The waterproof and breathable membrane 20 is disposed at the second end of the cylinder 21 away from the first plate 22 .

[0035] Furthermore, the second end of the cylinder 21 is snap-fitted with an inner cover plate 23 , a breathable pressure plate 24 is provided on the inner cover plate, and the waterproof breathable membrane is provided between the inner cover plate and the breathable pressure plate 24 .

[0036] Specifically, refer to Figure 1 When in use, the cover is arranged on the upper end of the outer shell 3 of the electric water-boiling appliance, so that the first end of the cylinder faces downward and the second end faces upward. When the electric water-boiling appliance is used to boil water or cook porridge, water vapor can flow out from the exhaust port of the upper cover 1. The exhaust port 10 is provided with an inner cover assembly 2, so that the steam can be discharged outward through the cylinder 21. In the process of steam discharge, it first passes through the exhaust hole 220 on the first plate 22, then flows along the cylinder 21 to the second end, and passes through the waterproof and breathable membrane 20 provided at the second end. Discharge, the present application is provided with a cylinder, the first end of the cylinder is spaced from the internal liquid surface of the electric water boiler when it is working, and the waterproof breathable membrane is spaced from the plate body at the first end. This method can make the waterproof breathable membrane 20 spaced a certain distance from the liquid surface, and by providing the first plate, so that when porridge is cooked in the electric water boiler, the bubbles generated by the liquid surface will contact the first plate first, wherein the exhaust hole 220 provided on the first plate is a micropore with a pore size between 0.1 mm and 2 mm, and bubbles are not easy to pass through the exhaust hole, reference Figure 8 、 Figure 9 The breathable pressure plate 24 is also provided with breathable holes. The holes on the breathable pressure plate 24 can play the same role as the exhaust holes 220. By using double-layer micropores and setting the waterproof breathable membrane away from the liquid surface, the risk of bubbles mixed with rice slurry contacting the waterproof breathable membrane can be effectively reduced, the probability of the waterproof breathable membrane being blocked is reduced, and the service life of the waterproof breathable membrane is increased.

[0037] Specifically, as a preferred embodiment, the first plate is integrally provided with the cylinder, and the upper cover, the cylinder, the inner cover plate and the breathable pressure plate are all made of plastic material.

[0038] On the other hand, by detachably connecting the inner cover assembly to the upper cover 1, after the water in the electric water boiler boils, the inner cover assembly can be removed to release the internal high-pressure steam, and then the upper cover 1 can be removed, thereby effectively avoiding the safety risks brought by high-temperature steam and improving safety.

[0039] On the other hand, the above arrangement also facilitates the disassembly and cleaning of the inner cover assembly.

[0040] It should be noted that the waterproof breathable membrane 20 is a membrane 20 that allows gases such as water vapor to pass through but does not allow liquids to pass through.
