And the valve core 2 cannot move up and down in the accommodating cavity 11 during the rotation process.

Preferably, an elastic member 5 is further disposed in the accommodating cavity 11, and the elastic member 5 may be a spring. The elastic member 5 is sleeved on the connecting portion 22, and the lower end of the elastic member 5 abuts against the step 23. When the pressure cooker is not used, the blocking part 21 can be pushed to move downwards by the elasticity of the elastic piece 5, so that the blocking part 21 blocks the air outlet 12.

Referring to fig. 4 and 7, a pressure regulating block 6 is further disposed in the accommodating chamber 11, and the pressure regulating block 6 is located between the inner side surface of the valve cap 4 and the elastic member 5. The upper end of the elastic member 5 abuts against the pressure regulating block 6.

Preferably, the pressure regulating block 6 is provided with a rotating hole 61, the shape of the rotating hole 61 is matched with the shape of the connecting part 22, and the connecting part 22 is inserted in the rotating hole 61. The shape of the rotation hole 61 may not be circular, preventing relative rotation between the pressure regulating block 6 and the connecting portion 22. When the switch 3 rotates by taking the length direction of the valve core 2 as an axis, the valve core 2 rotates along with the switch 3, and the pressure regulating block 6 rotates along with the valve core 2.

Preferably, the inner side surface of the valve cap 4 close to the pressure regulating block 6 is an abutting surface 42, a plurality of grooves 43 are arranged on the abutting surface 42 at intervals, correspondingly, a plurality of projections 62 are also arranged on the side surface of the pressure regulating block 6 close to the valve cap 4 at intervals, and the projections 62 can be inserted into the grooves 43 in a one-to-one correspondence manner. The sides of each groove 43 are preferably radiused to facilitate movement of the projection 62 from the groove 43 to the abutment surface 42 or from the abutment surface 42 to the groove 43 during rotation.

In summary, the principle of the voltage regulation block 6 for realizing voltage regulation is as follows: the user uses the length direction of case 2 as the axle and rotates switch 3, and switch 3 drives case 2 and rotates, and pressure regulating block 6 rotates along with case 2, and can not take place relative rotation between pressure regulating block 6 and case 2. During the rotation of the pressure regulating block 6, the projection 62 moves from the groove 43 to the abutment surface 42 or from the abutment surface 42 to the groove 43, during which the pressure regulating block 6 moves up and down in the accommodating chamber 11. Since the pressure adjusting block 6 abuts on the elastic member 5, the pressure adjusting block 6 moving up and down compresses or extends the elastic member 5. At this time, since the length of the elastic member 5 is changed, air pressure with different strength is also required to push the valve element 2 to move upwards, and then the air exhaust is completed. Therefore, the exhaust valve with the pressure regulating block 6 has better practicability because a user can control the air pressure during exhaust by rotating the switch 3.

Referring to fig. 8 and 9, the exhaust valve of the present invention has two exhaust modes, the first is automatic exhaust, when the pressure cooker is in use, the pressure inside the cooker body 92 rises, when the pressure is greater than the elasticity of the elastic member 5, the pressure can push the valve core 2 upwards and expose the gas outlet 12, and the gas inside the cooker body 92 can be exhausted to the outside through the gas outlet 12.

The second is manual exhaust, in the using process of the pressure cooker, a user can turn the switch 3 to drive the valve core 2 to move upwards and expose the air outlet 12, and the air in the cooker body 92 can be exhausted to the outside through the air outlet 12.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention.
