Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

A pressure-limiting valve of pressure cooker controlled by pressing comprises a valve body 012 and a fixed seat 010 fixedly arranged on a pressure cooker cover 011; the valve body 012 is mounted on the fixed seat 010, a sealing silica gel pad 009 is arranged between the fixed seat 010 and the pressure cooker cover 011, a pressure relief cavity 013 is formed between the fixed seat 010, the sealing silica gel pad 009 and the pressure cooker cover 011, and an air outlet 014 is arranged on the fixed seat 010; the valve body 012 comprises a valve core 002 arranged in a fixed seat 010, a sealing sleeve 001 arranged at the lower end of the valve core 002 and matched with an exhaust hole 015 arranged on a pressure cooker cover 011, a valve cap 004 arranged above the valve core 002, a pressure limiting valve spring 003 connecting the valve core 002 and the valve cap 004, an ejection piece 006 arranged above the valve cap 004 and connected with the valve cap 004, a control piece 008 arranged on the fixed seat 010, and a control spring 005 arranged between the ejection piece 006 and the fixed seat 010, wherein the ejection piece 006 is sleeved in the control piece 008, the lower end of the ejection piece 006 is provided with an outward protruding clamping hook 016, the inner side of the control piece 008 is provided with an upper clamping groove 017 and a lower clamping groove 018 matched with the clamping hook 016, the outer side of the control piece 008 is provided with an elastic button 019, and the inner side of the elastic button 019 is provided with a push button 020 extending to the lower clamping groove 018; the pressure relief cavity 013 communicates the gas outlet 014 with the vent hole 015. The gas outlet 014 is obliquely arranged, and the gas outlet direction is far away from the valve body 012. The valve body 012 further includes an ornament 007 mounted between the ejection member 006 and the control member 008.

When the valve cap works, the clamping position of the ejection piece is clamped in the two sides of the control piece by pressing the ejection piece downwards, the center table surface of the ejection piece presses the valve cap, and meanwhile, the valve cap presses the pressure limiting valve spring to generate spring force so as to work; when the exhaust valve is opened, the elastic buttons on two sides of the control piece are pressed, the clamping position on the ejection piece jumps out, the central table surface of the ejection piece leaves the valve cap under the action of the control spring force, the pressure limiting valve spring loses the force elasticity, a gap is formed between the valve core and the pot cover, and the pressure reduction and cover opening are completed after the exhaust.

The invention may be modified in many ways which will be obvious to a person skilled in the art, and such modifications are not to be considered as a departure from the scope of the invention. All such modifications as would be obvious to one skilled in the art are intended to be included within the scope of this claim.
