Problems solved by technology

[0002] In the electric pressure cooker currently available on the market, the heavy hammer type pressure limiting valve is directly sealed with the exhaust valve core through the heavy hammer. There are three problems in this sealing structure: first, the processing technology of the spherical heavy hammer is difficult to guarantee the absolute roundness of the spherical surface. Slight air leakage often occurs between the weight and the exhaust valve core; the second is that the spherical weight placed on the exhaust valve core will cause air leakage due to vibration or uneven work surface; the third is the error of the pressure limit pressure value of the spherical weight range does not guarantee the safe use of the product

Embodiment 1

[0015] Such as figure 1 , figure 2 As shown, the present invention includes a valve seat 2, a valve cover 1, a weight 3 and an exhaust valve core 4. The valve cover 1 is buckled on the valve seat 2, and the exhaust valve core 4 is located in the exhaust passage of the valve seat 2. The weight 3 is buckled on the exhaust valve core 4, and a thimble 5 is arranged in the exhaust valve core 4, and the thimble 5 and the exhaust channel of the exhaust valve core 4 are slidably sealed. In order to prevent the thimble 5 from slipping upwards from the exhaust valve core 4 , the top end of the exhaust valve core 4 is provided with a limiting flange 41 . In this embodiment, the flange 41 is integrated with the main body of the exhaust valve core 4, and the thimble 5 is made of silicone material. In order to save material and keep the thimble in a structural shape with a large top and a small bottom, the upper end of the thimble is in the shape of a "cross". shaped structure. When the...

Embodiment 2

[0018] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the position-limiting structure on the exhaust valve core 4 is a circlip structure 6 fixedly installed on the exhaust spool 4, and the circlip structure 6 is a shaft step clamp. reed.

Abstract

The invention relates to a pressure-limiting valve of an electric pressure cooker. The pressure-limiting valve comprises a valve seat, a valve cover, a hammer and a vent valve plug, wherein the valve cover is put on the valve seat, the vent valve plug is in an exhaust passage of the valve seat, and the hammer is put on the vent valve plug. The pressure-limiting valve is characterized in that the vent valve plug is internally provided with a thimble; the thimble and the exhaust passage of the vent valve plug are in sliding seal, and the hammer presses against the top of the thimble. The pressure-limiting valve solves the problem of air leakage caused by failure to ensure the absolute spherical roundness of the hammer when processing, and meanwhile overcomes the air leakage arising from unstable location of the hammer. The pressure vapor in the structure is not in direct contact with the spherical hammer, thus ensuring the relative stability of limited pressure valve, making sure that the highest stable limited pressure valve falls into the safe use range and guaranteeing the safety of the product and the property and personal safety of users.
