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.
