Problems solved by technology
However, when the bubbles are escaping, they will move close to the upper cover, and there is a gap between the intercepting grid and the upper cover, so that the effect of the intercepting grid cannot be fully exerted, resulting in the need to improve the bubble breaking and anti-overflow effect

The invention provides a bubble breaking structure, a steam valve, a cover body assembly and a cooking utensil. The bubble breaking structure comprises a body, the body is provided with a first structure and second structures, and the second structures are arranged on the periphery or the two sides of the first structure and matched with the first structure to form a bubble breaking area; and the first structure is a strip-shaped structure, the water contact angle of the bubble breaking area in the first direction is smaller than the water contact angle of the bubble breaking area in the second direction, the first direction is the extension direction of the first structure, and the second direction is the direction from the first structure to the second structure. According to the invention, the length-diameter ratio of bubbles can be increased by utilizing the difference of hydrophilic and hydrophobic properties, and finally, the bubbles are unbalanced and broken so that the effects of bubble breaking and overflow prevention are achieved. Meanwhile, compared with an interception grating, the bubble breaking area is beneficial to simplifying the structure of the steam valve, reducing the size of the steam valve, reducing the weight of the steam valve and reducing the product cost.
Description
technical field [0001] The present invention relates to the technical field of cooking utensils, in particular to a bubble breaking structure, a steam valve including the bubble breaking structure, a cover assembly including the steam valve, and a cooking utensil including the cover assembly. Background technique [0002] At present, cooking utensils such as electric rice cookers and electric pressure cookers generally use a combination of a smooth upper cover and an intercepting grid as the foam breaking structure. Bubbles and water vapor travel along the path of the intercepting grid, which greatly increases the contact area and probability of contact between the bubbles and the intercepting grid, so as to achieve the effect of breaking bubbles and preventing overflow. However, in the process of escaping the bubbles, they will move forward close to the upper cover, and there is a gap between the intercepting grille and the upper cover, so that the effect of the interceptin...
