Problems solved by technology

The disadvantage of this pressure cooker exhaust valve is: when the conical thimble is laterally offset relative to the valve core during the process of rising and falling, the pointed tip of the conical thimble is easy to cause damage to the exhaust hole of the valve core, As a result, the exhaust valve is not tightly sealed, resulting in air leakage.
The disadvantages of the solenoid valve type exhaust valve are: 1. High cost; 2. When the solenoid valve is powered off, the exhaust port opens quickly, which easily causes the pressure in the pot to be released instantaneously, and the ingredients in the pot spew out through the exhaust port.
However, the service life of the silicone sheet is short, and it is easy to age. Either the deformation is insufficient and the vent hole is closed, resulting in air leakage, or the deformation cannot be restored, resulting in the inability to exhaust and reduce pressure; the reliability is poor.
[0005] CN 202184617 U discloses a safe and fast pressure cooker lid, which is connected with the valve body opening and closing mechanism through the lid opening linkage mechanism to realize the opening and closing of the valve body when opening and closing the lid, but this structure is complex and It is necessary to provide braking force for opening and closing of the cover and the opening and closing of the valve body at the same time, so it is necessary to provide a large external braking force, and the strength of the material is high, and it is easy to damage the parts

Embodiment 1

[0025] refer to Figure 2-5

[0026] A pressure cooker, comprising a pot body and an upper cover that is covered with the pot body, the upper cover is provided with an exhaust valve, and the exhaust valve includes a valve body braking mechanism, a motion transmission mechanism, and a valve body;

[0027] The brake mechanism of the valve body is an axial ejector rod 2 that penetrates the upper cover and moves axially along the upper cover. The motion transmission mechanism is a radial connecting rod 3 that is arranged on the upper cover and moves radially along the upper cover. One end of the ejector rod 2 is in contact with the pot body as the trigger end 1A, and the trigger end 1A is a smooth curved surface to avoid scratching the pot body; the other end of the axial ejector rod 2 is in contact with the motion transmission mechanism and serves as the braking end 2B. The braking end 2B is provided with a first slope whose distance from the bottom end of the slope to the valve...

Abstract

The invention relates to a pressure cooker comprising a cooker body, an upper cover and an exhaust valve, wherein the exhaust valve comprises a brake mechanism of a valve body, a movement transmission mechanism and the valve body; the brake mechanism of the valve body comprises a triggering end, a braking end and a first resetting device; when the upper cover is covered, the brake mechanism of the valve body is positioned at a first position; when the upper cover is opened, the brake mechanism of the valve body is reset to a second position; the movement transmission mechanism comprises a first transmission part and a second transmission part; when the brake mechanism of the valve body is positioned at the first position, the movement transmission mechanism is positioned at a first transmission position; when the brake mechanism of the valve body is positioned at the second position, the movement transmission mechanism is positioned at a second transmission position; when the movement transmission mechanism is positioned at the first transmission position, the valve body is positioned at a sealing position; when the movement transmission mechanism is positioned at the second transmission position, the valve body is positioned at an opening position; the cooker body is provided with a triggering part; when the cover is covered, the triggering part is maintained at a first position; and when the cover is opened, the triggering part is disengaged from the triggering end, so that the brake mechanism of the valve body is maintained at a second position. The pressure cooker has the advantages of simple structure, low cost and good reliability.

Description

technical field [0001] The invention relates to a pressure cooker. Background technique [0002] Exhaust valves are all designed on the pot lids of existing pressure cookers. one is as figure 1 The mechanical exhaust valve shown includes a sleeve 101 , a valve body cover 102 , a valve body 103 , a tapered thimble 104 and a valve core 105 . When the pressure cooker starts to cook food, the gas in the pressure cooker is in a normal pressure state, and due to the effect of gravity, the conical thimble 104 pushes against the vent hole of the valve core 105, so that the pressure cooker is in a sealed state. As the gas pressure in the pressure cooker pot rises, the high-pressure gas pushes up the conical thimble 104, so that the gas is removed from the gap between the conical thimble 104 and the valve core 105, and the pressure in the pot is released. The disadvantage of this pressure cooker exhaust valve is: when the conical thimble is laterally offset relative to the valve co...
