[0002] With the improvement of living standards, pressure cookers have become popular in daily life. However, pressure cookers are prone to explosion due to improper use, posing a serious safety hazard. To solve this problem, manufacturers have designed a pressure relief valve on the lid of the pressure cooker. When the exhaust hole of the pressure limiting valve of the pressure cooker is accidentally blocked, the air pressure in the pot exceeds the working pressure of the pressure cooker, and the pressure relief valve opens to discharge the gas in the pot.

[0003] However, these traditional designs have some problems, such as large pressure fluctuations during pressure relief, unstable pressure relief process, easy clogging and difficult maintenance, all of which may affect the safety and use of pressure cookers. Summary of the Invention

[0006] In the above-mentioned novel pressure relief valve for pressure cookers, the top of the valve seat is provided with an external thread, the inner wall of the valve cap is provided with an internal thread matching the external thread, a sealing ring is provided between the valve seat and the valve cap for sealing, and a sealing groove for installing the sealing ring is provided on the valve seat.

[0007] In the above-mentioned novel pressure relief valve for pressure cookers, an anti-blocking groove is provided at the bottom of the valve seat to prevent the valve body from being blocked.

[0008] In the above-mentioned novel pressure relief valve for pressure cookers, a guide hole is provided at the center of the valve cap to facilitate the sliding of the valve core.

[0009] In the above-mentioned novel pressure relief valve for pressure cookers, the exhaust holes are evenly distributed around the guide hole.

[0010] In the above-mentioned novel pressure relief valve for pressure cookers, the locking portion and the elastic valve block are both made of elastic material.

[0011] Compared with the existing technology, this new pressure cooker pressure relief valve achieves more accurate pressure sensing and release through precisely designed pressure holes and exhaust mechanisms, thereby improving the stability of the valve body; and achieves a smoother pressure relief process through precisely designed valve cores and elastic elements, thereby reducing pressure fluctuations and improving product safety.

DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 、 Figure 2 As shown, this new type of pressure relief valve for pressure cookers includes a valve seat 1, a valve cap 2 and a valve core 3. The valve cap 2 is arranged on the valve seat 1, and a plurality of exhaust holes 4 for exhaust are opened on the valve cap 2. An elastic valve block 5 for fixing the valve core 3 is provided on the inner wall of the valve seat 1. A locking portion 6 is provided on the valve core 3. A sliding groove 7 is provided in the middle of the locking portion 6 to facilitate the valve core 3 to move up and down. The elastic valve block 5 is arranged in the sliding groove 7, and a gap 16 is provided between the elastic valve block 5 and the sliding groove 7. When the pressure relief valve is pressed, the valve core 3 moves up along the sliding groove 7 and discharges pressure outwards through the gap 16. A gap is formed between the sliding groove 7 and the elastic valve block 5 to discharge pressure. The valve core 3 is provided with a pressure block 8 at the bottom of the elastic valve block 5, and a pressure gear adjustment hole 9 for adjusting the pressure is provided at the center of the pressure block 8. The pressure relief valve is installed and connected to the pressure cooker through the pressure block 8, and the pressure gear adjustment hole 9 at the bottom is used to regulate the pressure.

[0017] To be more specific, an external thread 10 is provided on the top of the valve seat 1, and an internal thread 11 that matches the external thread 10 is provided on the inner wall of the valve bonnet 2. A sealing ring 12 is provided between the valve seat 1 and the valve bonnet 2 for sealing, and a sealing groove 13 for installing the sealing ring 12 is provided on the valve seat 1. The installation of the sealing ring 12 prevents pressure leakage at the connection between the valve seat 1 and the valve bonnet 2.

[0018] To be more specific, an anti-blocking groove 14 is provided at the bottom of the valve seat 1 to prevent the valve body from being blocked, thereby preventing blockage from causing a safety hazard to the pressure relief valve.

[0019] In further detail, a guide hole 15 is opened at the center of the valve cap 2 to facilitate the sliding of the valve core 3.

[0020] To be more specific, the exhaust holes 4 are evenly distributed around the guide hole 15 , and the even distribution of the exhaust holes 4 helps to improve the stability of the product pressure relief.

[0021] In further detail, both the locking portion 6 and the elastic valve block 5 are made of elastic material, and the friction between the locking portion 6 and the elastic valve block 5 is reduced by making them of elastic material.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0023] Although this document frequently uses terms such as valve seat 1, valve bonnet 2, valve core 3, vent hole 4, elastic valve block 5, retaining portion 6, sliding groove 7, pressure block 8, pressure-stage adjustment hole 9, external thread 10, internal thread 11, sealing ring 12, sealing groove 13, anti-blocking groove 14, guide hole 15, and gap 16, the use of other terms is not excluded.
