The valve core 8 is arranged in a containing cavity in the valve body 7 and can float up and down in the containing cavity. When the cooking utensil of the embodiment performs high-pressure cooking, the valve core 8 floats downwards to the first position of the valve body 7, and at the moment, the valve core 8 seals the exhaust port 9 on the valve body 7, so that the cooking cavity forms a high-temperature and high-pressure sealed environment. When the pressure in the cooking cavity exceeds the safely set pressure, the valve core 8 floats upwards to the second position of the valve body 7 under the action of the pressure in the accommodating cavity, at the moment, the valve core 8 is separated from the valve body 7, the exhaust port 9 on the valve body 7 is opened, so that high-pressure gas in the cooking cavity is exhausted through the exhaust port 9, and the pressure in the cooking cavity is reduced.

Fig. 5 is a first cross sectional view of the pressure relief valve when the pressure relief valve is not relieving pressure in the embodiment of the present invention; fig. 6 is a first cross-sectional view of the pressure relief valve according to the embodiment of the present invention. As shown in fig. 4, 5, and 6, a stopper 10 is provided in the relief valve 6, and the stopper 10 fixes the valve body 8 to the second position of the valve body 7 when the relief valve 6 is relieved. Specifically, the limiting device 10 is an elastic clamp spring, and the elastic clamp spring is an elastic element. The elastic clamp spring is in a circular ring shape. An annular mounting groove is formed in the inner wall of the valve body 7, and the elastic clamp spring is arranged in the mounting groove and surrounds the valve core 8. The periphery of the valve body 7 is provided with an annular limiting groove 11. When this embodiment cooking utensil carries out high-pressure cooking, case 8 is located the first position of valve body 7, and at this moment, the spacing groove 11 of case 8 staggers each other with the mounting groove of valve body 7, and the elasticity jump ring in the mounting groove offsets with the outer wall of case 8, and case 8 can float in valve body 7. When culinary art cavity internal pressure surpassed the pressure of safe settlement, case 8 is under the effect of holding cavity internal pressure, upwards float to the second position of valve body 7, at this moment, case 8's spacing groove 11 corresponds with valve body 7's mounting groove, the elasticity jump ring in the mounting groove is under the effect of its own elasticity, go into spacing groove 11 in the card, thereby be fixed in the second position of valve body 7 with case 8, make case 8 unable continuation float, thereby make the distance between case 8 and the valve body 7 keep unchangeable, and then guarantee that the opening size that gas vent 9 was opened by case 8 is unchangeable, realize the slow stable effect of pressure release, avoid relief valve 6 to release suddenly, and spray to all around at random. The embodiment can realize directional and stable pressure relief and has higher reliability. This embodiment is fixed case 8 through the elasticity jump ring, simple structure, and the installation and the dismantlement of being convenient for.

Fig. 7 is a schematic structural diagram of the elastic clamp spring in the embodiment of the present invention. As shown in fig. 7, the elastic snap spring is formed with a protrusion 12 protruding inward. When the valve core floats to the second position of the valve body, the convex part 12 of the elastic clamp spring is clamped into the limiting groove of the valve core to fix the valve core, so that the stability of the elastic clamp spring for fixing the valve core is ensured, and the elastic clamp spring is prevented from losing efficacy.

As shown in fig. 7, the elastic clamp spring is provided with an installation opening 13, so that the elastic clamp spring has a buffer space to facilitate installation of the elastic clamp spring.

As shown in fig. 4, 5 and 6, the valve body 8 includes a stem 801 and a bonnet 802, and the stem 801 is connected to the bonnet 802 by a screw or the like. The valve rod 801 is disposed in the accommodating cavity of the valve body 7 and can float up and down in the accommodating cavity. A bonnet 802 covers the top of the valve body 7 for sealing the exhaust port 9 of the valve body 7. When the predetermined pressure is reached in the valve body 7, the valve rod 801 floats upwards under the predetermined pressure to float to the second position of the valve body 7, and at this time, the valve rod 801 drives the bonnet 802 to separate from the top of the valve body 7, and the exhaust port 9 is opened. The preset pressure refers to the pressure in the accommodating cavity of the valve body 7 when the pressure in the cooking cavity exceeds the safely set pressure.

As shown in fig. 4, 5 and 6, a first boss is disposed at a lower portion of the valve rod 801, a second boss is correspondingly disposed on an inner wall of the valve body 7, a return spring 15 is sleeved on the valve rod 801, and the return spring 15 is located between the first boss and the second boss. One end of the return spring 15 acts on the first boss and the other end of the return spring 15 acts on the second boss.
