As shown in fig. 1 to 3, the cover of the present embodiment includes: a cover body 10, a vent pipe 20, a pressure limiting valve 30 and an anti-overflow cover 40. Wherein, the exhaust pipe 20 is arranged on the cover body 10 in a penetrating way, and an exhaust channel 1 communicated with the outside atmosphere is arranged in the exhaust pipe 20; the pressure limiting valve 30 blocks the exhaust port of the exhaust passage 1; the anti-overflow cover 40 covers the bottom of the exhaust pipe 20, the anti-overflow cover 40 is provided with an overflow port 43, the overflow port 43 is communicated with the air inlet of the exhaust passage 1 through a cavity in the anti-overflow cover 40, and the bottom of the overflow port 43 is higher than the bottom of the air inlet of the exhaust passage 1.

By applying the technical scheme of the embodiment, the overflow preventing cover 40 is provided with the overflow opening 43, and the opening wall of the overflow opening 43 has the function of breaking bubbles. When the pressure is released and the air is exhausted, the liquid in the cooking cavity boils to generate a large amount of bubbles, once the bubbles are contacted with the overflow port, the port wall of the overflow port 43 can puncture the bubbles, so that the liquid in the bubbles flows down along the side wall of the anti-overflow cover 40, the air in the bubbles enters the overflow port 43 and is exhausted to the outside from the exhaust channel 1 of the exhaust pipe 20, and the probability of the pot overflow phenomenon is effectively reduced. In addition, the bottom of the overflow opening 43 of this application is higher than the bottom of the air inlet of exhaust passage 1, and the overflow opening of this application is seted up in the higher position department of anti-overflow cover promptly, and the probability that the bubble got into in the overflow opening 43 can be reduced to the height that promotes the overflow opening 43 to the probability in the liquid that has reduced the cooking chamber got into exhaust passage 1 has promoted the anti-overflow effect of anti-overflow cover 40.

As shown in fig. 3 and 5, in the present embodiment, the distance H between the bottom of the flow-passing port 43 and the bottom of the intake port is between 1mm and 5 mm. In the structure, the setting position of the overflow port 43 is not lower than that of the air inlet, so that the overflow port 43 is arranged at the higher position of the overflow-proof cover, the probability that bubbles enter the overflow port 43 is reduced, the probability that liquid in the cooking cavity enters the exhaust channel 1 is reduced, and the overflow-proof effect of the overflow-proof cover 40 is improved. Preferably, the distance H between the bottom of the flow-passing opening 43 and the bottom of the air inlet opening is 3 mm.

As shown in fig. 3 and 5, in the present embodiment, the spill-proof cover 40 includes a bottom wall 41 and a side wall 42 surrounding the bottom wall 41, and the top of the side wall 42 is provided with a downwardly extending notch that forms the flow opening 43. In the above-mentioned structure, if the through-flow opening is the through-hole of setting on lateral wall 42, under the thicker condition of lateral wall 42, the degree of difficulty of seting up the through-hole on lateral wall 42 will greatly increased, form the processing of the through-flow opening of being convenient for through-flow opening 43 through the mode that sets up the breach on lateral wall 42, reduced the processing cost of anti-overflow cover 40.

As shown in fig. 2 and 3, in the present embodiment, the upper surface of the side wall 42 abuts against the lower surface of the lid body 10, and the depth of the notch is between 0.5mm and 2 mm. In the above-mentioned structure, the breach setting is in the top of anti-overflow cover 40, and the degree of depth of breach is low, and this kind of mode of setting has further reduced the bubble of culinary art intracavity and has entered into the probability in overflowing mouth 43 to reduce the probability that the liquid of culinary art intracavity entered into in exhaust passage 1, promoted the anti-overflow effect of anti-overflow cover 40. In addition, if the depth of the notch is too great, the probability of air bubbles entering the flow-through opening 43 is increased. If the depth of the notch is too small, the exhaust efficiency of pressure relief exhaust is reduced. Setting the depth of the notch between 0.5mm and 2mm can minimize the probability of liquid entering the exhaust passage 1 while ensuring the exhaust efficiency.

As shown in fig. 3, in the present embodiment, the spill-proof cover 40 includes a bottom wall 41 and a side wall 42 surrounding the circumferential outer side of the bottom wall 41, the overflow opening 43 is located on the side wall 42, the cavity in the spill-proof cover 40 includes the first flow channel 2 located between the inner surface of the side wall 42 and the side wall of the vent pipe 20, and the width of the first flow channel 2 is between 1.5mm and 2 mm. In the above structure, the first flow passage 2 communicates with the overflow vent 43 of the overflow preventing cover 40. When air bubbles enter from the overflow port 43, the side wall 42 of the anti-overflow cover 40 and the side wall of the vent pipe 20 can break the bubbles due to the small width of the first flow channel 2, so that the probability of liquid entering the vent channel 1 is further reduced, and the bubble breaking effect of the anti-overflow cover 40 is improved.

As shown in fig. 3, in the present embodiment, the cavity in the spill-proof cover 40 further includes a second flow channel 3 located below the first flow channel 2 and disposed at an angle to the first flow channel 2, and the air inlet of the air exhaust channel 1 is communicated with the flow passing port 43 through the first flow channel 2 and the second flow channel 3 in sequence. In the above-mentioned structure, second runner 3 just is the angle setting with first runner 2 intercommunication, consequently when the bubble flows into second runner 3 from first runner 2 in, the runner wall of second runner 3 also can play the effect of broken bubble, and above-mentioned structure has further reduced the probability that liquid enters into in the exhaust passage 1, has promoted the broken bubble effect of anti-overflow cover 40.
