Description

Technical Field

[0001] The utility model relates to the technical field of pressure cookers, in particular to a pressure limiting device for a pressure cooker. Background Art

[0002] A pressure cooker is a type of kitchen cooker. It uses the physical phenomenon that the boiling point of liquid increases under higher pressure to apply pressure to water, allowing the water to reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. It can be used to heat steamed food to above 100°C. In high altitude areas, using a pressure cooker can avoid the problem of lowering the boiling point of water and making it difficult to cook food.

[0003] The existing pressure cooker limiting device is not convenient for adjusting the critical pressure value of the pressure limiting device according to needs, and has poor versatility. In addition, the existing pressure limiting device is easily blocked by food residues during use, which reduces the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pressure limiting device for a pressure cooker, which has the advantages of good anti-blocking effect and adjusting the critical pressure value, and solves the above technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a pressure limiting device for a pressure cooker, comprising a mounting seat, a support column is symmetrically fixedly installed on the top of the mounting seat, a knob is installed on the top of the support column, a threaded rod is fixedly installed on the top of the knob, a base is fixedly installed on the top of the mounting seat, a spring is sleeved on the outer wall of the threaded rod, a moving ring is sleeved on the outer wall of the threaded rod, a sealing ring is fixedly installed on the bottom end of the moving ring, an anti-blocking plate is installed on the bottom end of the mounting seat, a fixed column is fixedly installed on the bottom end of the anti-blocking plate, a sleeve is rotatably installed on the outer wall of the fixed column, and a cleaning rod is fixedly installed on the side end of the sleeve.

[0008] Preferably, an air outlet is provided through the middle of the mounting seat, and a connecting block is installed inside the air outlet.

[0009] Through the above technical solution, when a certain pressure is accumulated inside the pressure cooker, the gas inside the pressure cooker is discharged from the pressure cooker through the gas outlet.

[0010] Preferably, the bottom end of the threaded rod can be rotatably mounted on the top end of the base.

[0011] Through the above technical solution, the bottom end of the threaded rod can be rotatably mounted on the top end of the base, and the threaded rod can be driven to rotate by turning the knob.

[0012] Preferably, an adjusting ring is threadedly mounted on the outer wall of the threaded rod, and the adjusting ring is mounted on the top of the spring.

[0013] Through the above technical solution, when the threaded rod rotates, the adjusting ring is driven to move up and down along the outer wall of the threaded rod, so that the compression amount of the spring is adjusted through the adjusting ring.

[0014] Preferably, a limiting hole is formed through the top of the movable ring, and the limiting hole is sleeved on the outer wall of the supporting column.

[0015] Through the above technical solution, the support column and the limiting hole at the top of the moving ring are sleeved together, and when the moving ring moves upward, the support column can limit the movement of the moving ring.

[0016] Preferably, a cleaning block is fixedly mounted on the top end of the cleaning rod.

[0017] Through the above technical solution, the top of the cleaning block is in contact with the bottom of the anti-blocking plate. When the cleaning block rotates, it rotates around the anti-blocking plate, thereby scraping the bottom of the anti-blocking plate, thereby preventing the anti-blocking plate from being blocked by food residues.

[0018] Compared with the prior art, the utility model provides a pressure limiting device for a pressure cooker, which has the following features:

[0019] Beneficial effects:

[0020] 1. The utility model installs the mounting base on the top of the pressure cooker. During the use of the pressure cooker, the gas inside the pressure cooker moves to the top of the pressure cooker. When a certain pressure is accumulated inside the pressure cooker and exceeds a critical value, the gas gathers at the gas outlet and drives the moving ring to move to the top. The moving ring moves upward and drives the sealing ring to move upward, thereby moving away from the gas outlet and compressing the spring. At this time, the gas inside the pressure cooker is discharged from the gas outlet. After the gas inside the pressure cooker is discharged, the spring loses pressure and needs to restore elasticity, thereby driving the moving ring to move downward. The moving ring moves downward and drives the sealing ring to block the gas outlet again. The knob can be turned, and the knob rotation drives the threaded rod rotation. The threaded rod rotation drives the adjusting ring to move up and down, thereby changing the compression amount of the spring, thereby adjusting the critical pressure value of the device body.

[0021] 2. The utility model provides a cleaning block. When the gas inside the pressure cooker accumulates at the anti-blocking plate, a certain airflow will be generated. The sleeve is sleeved on the outer wall of the fixed column. The sleeve rotates around the sleeve driven by the airflow. The rotation of the sleeve drives the cleaning rod to rotate. The rotation of the cleaning rod drives the cleaning block to rotate, so that the cleaning block scrapes the anti-blocking plate, thereby preventing food residues from clogging the anti-blocking plate.

[0031] Specifically, an adjusting ring 14 is threadedly installed on the outer wall of the threaded rod 4, and the adjusting ring 14 is installed on the top of the spring 6. The advantage is that when the threaded rod 4 rotates, the adjusting ring 14 is driven to move up and down along the outer wall of the threaded rod 4, thereby adjusting the compression amount of the spring 6 through the adjusting ring 14.

[0032] Specifically, a limiting hole 15 is formed through the top of the movable ring 7, and the limiting hole 15 is sleeved on the outer wall of the support column 2.

[0034] When in use, by installing the mounting base 1 on the top of the pressure cooker, during the use of the pressure cooker, the gas inside the pressure cooker moves to the top of the pressure cooker. When a certain pressure is accumulated inside the pressure cooker and exceeds a critical value, the gas gathers at the gas outlet 13 and drives the moving ring 7 to move toward the top. The moving ring 7 moves upward and drives the sealing ring 8 to move upward, thereby moving away from the gas outlet 13 and compressing the spring 6. At this time, the gas inside the pressure cooker is discharged from the gas outlet 13. When the gas inside the pressure cooker is discharged, the spring 6 loses pressure and needs to restore its elastic force, thereby driving the moving ring 7 to move downward. The moving ring 7 moves downward and drives the sealing ring 8 to block the gas outlet 13 again. , and the knob 3 can be turned, the knob 3 rotates to drive the threaded rod 4 to rotate, and the threaded rod 4 rotates to drive the adjusting ring 14 to move up and down, thereby changing the compression amount of the spring 6, so as to adjust the pressure critical value of the device body.
