Referring to fig. 1 to 10, an embodiment of the exhaust device of a pressure cooker of the present invention: including exhaust assembly 200 and control assembly 100.
Wherein the vent assembly 200 includes a push plate link 210 and a float 220, the push plate link 210 having a first station and a second station that limit and allow movement of the float 220 to a position that closes the vent path of the pressure cooker. Wherein, the push plate connecting rod 210 limits the float 220 to move to the position for closing the vent channel of the pressure cooker as a first station, and the push plate connecting rod 210 allows the float 220 to move to the position for closing the vent channel of the pressure cooker as a second station.
The float 220 can cooperate with the exhaust passage 221 of the pressure cooker, when the pressure in the pressure cooker is less than a certain value, the pressure is not enough to jack the float 220, and the gas in the pressure cooker is exhausted through the exhaust passage 221; when the pressure in the pressure cooker is greater than a certain value, the pressure in the pressure cooker overcomes the gravity of the float 220 to lift up the float 220, thereby sealing the exhaust passage 221. In the present application, by using the push plate connecting rod 210, when the pressure in the pressure cooker is greater than a certain value, the float 220 can be restricted from rising by making the push plate connecting rod 210 at the first station, so that the air can be continuously discharged through the air discharge passage 221, thereby providing a non-pressure cooking mode for the pressure cooker.
The control assembly 100 includes a lever element 110, an exhaust button 120, a reset button 140, a lever reset 150, and a link reset 130. The control assembly 100 is configured to control the movement of the push plate link 210 between the first and second stations. Namely, the operation mode of the pressure cooker can be switched between the following two operation modes by controlling the relative positions of the push plate connecting rod 210 and the float 220.
Pressureless cooking mode-pressureless cooking mode in which the float 220 is restricted from moving to a position closing the pressure cooker vent passage with the push plate link 210 in the first station, and the vent is continued with the vent passage 221 fitted to the float 220.
Pressure cooking mode-pressure cooking mode in which the push plate link 210 is in the second position, allowing the float 220 to move to a position closing the pressure cooker vent passage, so that the float 220 can be normally raised by the pressure in the pressure cooker, and the vent passage 221 is sealed by the float 220.
The control assembly 100 controls the push plate connecting rod 210 of the exhaust assembly 200 to move, so that the push plate connecting rod 210 can move between a first station and a second station, when the push plate connecting rod 210 is positioned at the first station, the floater 220 cannot move towards a position for closing the exhaust channel of the pressure cooker under the action of the pressure in the pressure cooker, so that the pressure cooker can continuously exhaust through the exhaust channel 221, and the non-pressure cooking effect is achieved.
The exhaust device of the pressure cooker has simple and reliable structure, improved production and assembly efficiency and lower cost.
In the embodiment of the invention, the push plate connecting rod 210 is provided with the through hole 211, the size of the through hole 211 is matched with that of the floater 220, the push plate connecting rod 210 avoids the floater 220 by using the through hole 211, when the push plate connecting rod 210 is positioned at a first station, the through hole 211 moves along with the push plate connecting rod 210 to be staggered with the position of the floater 220, the floater 220 cannot smoothly rise through the through hole 211, and the push plate connecting rod 210 presses the floater 220 to limit the floater 220 to move to the position for closing the exhaust channel of the pressure cooker under the pressure action in the pressure cooker; when the push plate connecting rod 210 is in the second station, the through hole 211 moves along with the push plate connecting rod 210 to a position corresponding to the position of the floater 220, so that the floater 220 is allowed to rise smoothly through the through hole 211, and the push plate connecting rod 210 avoids the floater 220 and allows the floater 220 to move towards a position for closing the exhaust channel of the pressure cooker under the pressure action in the pressure cooker.
In other embodiments, the push plate link 210 can be configured to avoid the float 220 in other manners, for example, the push plate link 210 is provided with a limiting portion. When the push plate connecting rod 210 is positioned at the first station, the limiting part is positioned above the position of the floater 220 and limits the floater to move to the position for closing the exhaust channel of the pressure cooker; when the push plate link 210 is in the second position, the restriction portion is clear of the float 220 above its position, allowing the float 220 to move toward a position closing the pressure cooker vent passage. The limiting portion may be independently disposed on the push plate connecting rod 210, or may be a part of the push plate connecting rod 210, and specifically, the structure and the position of the limiting portion may be changed correspondingly according to the structure of other components of the exhaust apparatus, which is not described herein again.
In the embodiment of the present invention, the control assembly 100 is provided with a lever member 110, an exhaust button 120, and a link reset 130. The lever element 110 has two arms, wherein the two arms are a first arm 112 and a second arm 113. The exhaust button 120 is used for pressing the first force arm 112 to tilt the second force arm 113. The link reset 130 is adapted to apply a force to the push plate link 210 that moves in the direction of the lever element 110.
