Problems solved by technology

[0005] Traditionally, this air pressure control device controlled by magnetism and closed by magnetic balls still has the following deficiencies: 1. The magnetic balls are easy to rust, which not only pollutes food, but also reduces the service life and quality of the device. It will be affected; 2. The moving of the magnetic parts to achieve the approach or distance from the sphere will cause the overall length of the device to be unfavorable for installation on the pot cover
[0009] In the above-mentioned documents, when the magnetic component and the pressure ball are far away, because the two still have mutual attraction, the pressure ball is not easy to automatically fall to the through hole, and there is also the defect that the action is not crisp and neat, which is not conducive to the realization of precise control

Embodiment approach 1

[0031] Implementation Mode 1: Refer to figure 1 and figure 2 , in the electric pressure cooker, the air pressure control device includes a moving mechanism 1 with a magnet, a crowbar mechanism 2, a magnet 3, a magnetic component 4, a sphere 5, a ball basket 6 and a pressure relief box 7; wherein: the pressure relief box 7 is formed with steam Passage 71, is formed with the through hole 72 that is convenient to spheroid 5 to fit in steam passage 71, and spheroid 5 is made of stainless steel or pottery or glass, and spheroid 5 can be placed in through hole 72 and steam passage 71 is closed; Crowbar mechanism 2. One end 21 is in contact with the sphere 5. The other end 22 of the crowbar mechanism 2 is provided with a magnetic component 4 with the same polarity as the magnet 3. The magnet 3 is located above the magnetic component 4; a ball basket 6 is provided above the through hole 72. Have a pressure relief hole 61 on the 6, and the basketball basket 6 can cover the sphere 5 t...

Embodiment approach 2

[0032] Implementation mode two: refer to image 3 and Figure 4 The other end 22 of the crowbar mechanism 2 is provided with a magnetic part 4 of opposite polarity to the magnet 3. The magnet 3 is located below the magnetic part 4. The moving mechanism 1 drives the magnet 3 to move and approach the magnetic part 4. The magnetic part 4 is attracted by the magnet 3. The function of the ball 5 is lifted away from the through hole 72 through the crowbar mechanism 2 to release the pressure; the moving mechanism 1 drives the magnet 3 to move away from the magnetic part 4, the sphere 5 is affected by its own gravity and the magnetic part 4 is repelled by the magnet 3 The role of the crowbar mechanism 2 makes the ball 5 coincide with the through hole 72 to close it. For other parts, please refer to the first embodiment, which can also achieve the purpose of the invention.

Abstract

The invention discloses an improvement of an air pressure control structure in an electric pressure cooker. An air pressure control device comprises a crow bar mechanism and a moving mechanism with amagnet; a sphere made from stainless steel or ceramics or glass can be matched with a through hole of a steam channel and then closed; closing of the sphere to the through hole is controlled by one end of the crow bar mechanism, and a magnetic component with the same polarity as the magnet is arranged at the other end of the crow bar mechanism; the magnetic component is located on the lower portion of the magnet; the moving mechanism drives the magnet to move and is close to the magnetic component, and the magnetic component is subjected to the action of the magnet to make the sphere lifted away from the through hole through the crow bar mechanism to achieve pressure relief; the moving mechanism drives the magnet to move to be away from the magnetic part, the sphere is subjected to the action of the dead weight, the magnetic component is subjected to the action of the magnet, and the sphere is matched with the through hole through the crow bar mechanism to achieve closing. The sphere can be made from the material without magnetism, and when the magnet is away from the sphere, the sphere can close the through hole rapidly.

Description

technical field [0001] The invention belongs to the field of household appliances, and relates to an improvement of an air pressure control structure in an electric pressure cooker. More specifically, it is a device for controlling air pressure by using a lever mechanism to close or lift a through hole by a sphere through the action of a magnetic field. And an electric pressure cooker containing the device. Background technique [0002] At present, the electric pressure cooker has the characteristics of high temperature and high pressure, which can cook food quickly, and is widely used in families or canteens, and because its temperature and pressure can be precisely controlled, it is more and more popular. [0003] In a pressure cooker, high temperature and high pressure are usually achieved by sealing the gas channel through hole with a sphere. Since the heating temperature in the pot is continuously rising and the inside of the pot is closed, the pressure and temperature ...
