Specifically, referring to fig. 8 to 10, in the second embodiment, theinner lid 210 has theair vent hole 211, thebubble breaker 100 is installed at theair vent hole 211, theair vent hole 211 constitutes theair outlet 12 of thebubble breaker 100, thebubble breaker body 1 is provided with theair inlet 11, and the air inlet channel 15 is theair inlet 11, so that the steam in the pot of thecooking utensil 300 is exhausted from theair vent hole 211 after passing through the bubble breaker 100 (specifically, in the second embodiment, theair vent hole 211 is provided with theair vent pipe 213, the lower end of theair vent pipe 213 is communicated with the bubble breaking cavity 2, and the upper end of theair vent pipe 213 is provided with the air vent valve 215), so that the bubble breaking and overflow preventing effect of thecooking utensil 300 is relatively good.

Thebubble breaker body 1 is detachably connected to theinner cap 210, and, in particular, in the second embodiment, a through hole is formed through the bottom of thebubble breaker body 1, a hangingshaft 212 is provided on the lower surface of theinner lid 210 corresponding to the through hole (specifically, in the second embodiment, theexhaust hole 211 is provided with anexhaust pipe 213, anexhaust valve 215 is installed on the upper end of theexhaust pipe 213, and the lower end of theexhaust pipe 213 is connected with the hangingshaft 212 by screw thread), and the lower end of the hangingshaft 212 extends out of thefoam breaker body 1 from the through hole and extends laterally to form a stop part, so as to limit the foam breakermain body 1 downwards (since in the second embodiment, the stopping portion of the hangingshaft 212 is clamped with the inner cover below the foam breakermain body 1, a gap is formed between the stopping portion and the foam breakermain body 1 in the up-down direction), so that the foam breakermain body 1 is relatively convenient and labor-saving to disassemble and assemble.

Thecooking utensil 300 is subjected to foam breaking and overflow prevention by arranging thefoam breaker 100, when thecooking utensil 300 is a pressure cooker, the foam breaking and overflow prevention effect of thefoam breaker 100 is related to the heating power of thecooking utensil 300, specifically, thecooking utensil 300 further comprises a heating device, and when the heating power of the heating device is 200-1200W, the foam breaking and overflow prevention effect of thefoam breaker 100 is relatively good. Similarly, thecooking appliance 300 further comprises an exhaust device, and when thecooking appliance 300 exhausts and reduces the pressure, the ratio of the power-on time to the intermittent time of the exhaust device is more than 1: 30, the foam breaking and overflow preventing effect of thefoam breaker 100 is relatively good.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
