[0035] The present embodiment mainly describes a multi-position pressure regulating valve, which is specifically as follows:

[0036] As shown in Figure 1 , Figure 2 , the multi-position pressure regulating valve comprises a pressure regulating valve main body detachably connected with a pot cover, wherein the pot cover is provided with a mounting seat 2, and the mounting seat 2 is fixed with a connecting valve stem 4. Specifically, the mounting seat 2 is provided with a groove 2b, and the connecting valve stem 4 is provided with a connecting seat 4a corresponding to the groove 2b, and the connecting seat 4a is embedded in the groove 2b, so that the connecting valve stem 4 is fixedly connected with the mounting seat 2.

[0037] The connecting valve stem 4 is provided with threads, and the mounting seat 2 is fixedly connected with the pressure cooker through the threads on the connecting valve stem 4.

[0038] The pressure regulating valve main body is provided with a rotating part 1, and the rotating part 1 is provided with a main body piece 6, a limiting block 5 and a plugging piece 3. The main body piece 6 is provided with a through hole 6c, and the connecting valve stem 4 is inserted into the through hole 6c so that the plugging piece 3 and the connecting valve stem 4 abut against each other.

[0039] The connecting valve stem 4 is provided with an air passage 4b for connecting the pressure cooker with the outside world, for the gas in the pressure cooker to flow, and the blocking piece 3 is used to block the air passage 4b. Preferably, the blocking piece 3 is provided with a plug 3a made of high-temperature-resistant rubber material. One end of the plug 3a is fixedly arranged on the blocking piece 3, and the other end is conically inserted into the air passage 4b of the connecting valve stem 4. The plug 3a is made of elastic rubber material to block the air passage 4b, so that the gas in the pressure cooker can be effectively prevented from flowing out through the air passage 4b when the plug 3a is blocked, and the pressure cooker is in a closed high-pressure environment when the food is not boiled.

[0040] As Figures 2-4 The main body 6 is rotatably clamped on the blocking piece 3. Specifically, the inner side wall of the blocking piece 3 is provided with a first convex edge 3b, and the outer side wall of the main body 6 is provided with a first annular clamping groove 6a. The first convex edge 3b is clamped in the first annular clamping groove 6a, so that the main body 6 is rotatably clamped on the blocking piece 3, and the stability of the connection between the main body 6 and the blocking piece 3 is ensured, and the main body 6 will not easily fall off.

[0041] The limiting block 5 is arranged between the main body 6 and the rotating piece 1, and can slide up and down between the blocking piece 3 and the main body 6. Specifically, the limiting block 5 is sleeved on the main body 6, one end of the main body 6 is provided with an outwardly extending convex rib 6b, the other end of the main body 6 is rotatably clamped on the blocking piece 3, the blocking piece 3 is provided with a blocking surface 3c, the convex rib 6b, the blocking surface 3c and the main body 6 jointly form a sliding groove, and the limiting block 5 slides in the sliding groove. The convex rib 6b and the blocking surface 3c jointly constrain the maximum range of the limiting block 5 sliding up and down.

[0042] The rotating piece 1 is rotatably arranged on the limiting block 5. Specifically, the rotating piece 1 is provided with a second convex edge 1d, and the limiting block 5 is provided with a second annular clamping groove 5a. The second convex edge 1d is clamped in the second annular clamping groove 5a, so that the rotating piece 1 is rotatably arranged on the limiting block 5, and the stability of the connection between the rotating piece 1 and the limiting block 5 is ensured, and the rotating piece 1 will not easily fall off.

[0043] The rotating piece 1 is integrally formed with the main body 6, the blocking piece 3 and the limiting block 5 in the rotating piece 1. The connecting valve stem 4 inserted into the through hole 6c of the main body 6 makes the rotating piece 1 detachably arranged on the mounting seat 2. In the working process of the pressure cooker, the gas passing through the air passage 4b in the connecting valve stem 4 can easily blow out the plug 3a inserted into the air passage 4b and the rotating piece 1 with the plug 3a, causing accidents.

[0044] The one end of the connecting valve stem 4 inserted into the through hole 6c is provided with a convex block 4c. In the use process of the pressure regulating valve body, the convex block 4c can effectively reduce the back and forth shaking amplitude of the main body 6 in the use process, and ensure the stability of the positional relationship between the components.

[0045] As shown in Figure 5 , the mounting seat 2 is provided with several levels of different gear grooves, and the bottom of the mounting seat 2 is provided with an opening 2g. Preferably, the gear grooves are divided into three, namely high-pressure gear groove 2d, low-pressure gear groove 2e and exhaust gear groove 2f. The three gear grooves are sequentially arranged along the inner wall of the mounting seat 2, and each gear groove is provided with another identical gear groove which is centrally symmetrical in the mounting seat 2. Among them, the high-pressure gear groove 2d is another gear groove which is centrally symmetrical in the mounting seat 2, that is, the opening 2g at the bottom of the mounting seat 2.

[0046] The rotating part 1 is provided with an insertion end 1c which is inserted into the gear groove. Preferably, the insertion end 1c is two, and the two insertion ends 1c are centrally symmetrical on the rotating part 1. According to the insertion of the insertion end 1c into different gear grooves, the pressure regulating valve is also divided into three different states.

[0047] As shown in Figure 1 , Figure 2 , the first state, the insertion end 1c is inserted into the high-pressure gear groove 2d. At this time, the limiting block 5 is separated from the plugging part 3, and the limiting block 5 and the convex rib 6b on the main part 6 abut each other. The plug 3a on the plugging part 3 is inserted into one end of the air channel 4b, and the air channel 4b is blocked, so that the inside of the pressure cooker is in a high-pressure state. The food in the pot is cooked more soft and rotten. When the air pressure in the pot exceeds the air pressure in the high-pressure state of the pressure cooker, the gas in the pot will lift the plug 3a upward through the air channel 4b, and the gas in the pot will be discharged. At the same time, the high-pressure state in the pot body is maintained, and the safety of the user is ensured.

[0048] As shown in Figure 9 , Figure 10 , the second state, the insertion end 1c is inserted into the low-pressure gear groove 2e. At this time, the limiting block 5 is between the plugging part 3 and the convex rib 6b, and the two ends are not abutted with the blocking surface 3c on the plugging part 3 or the convex rib 6b. At this time, the plug 3a on the plugging part 3 is inserted into the air channel 4b to block the air channel 4b. However, when the air pressure in the pot is large, the gas in the pot will lift the plugging part 3 with the plug 3a upward until the convex rib 6b abuts against the limiting block 5. In this state, the gas in the pressure cooker is allowed to pass through the air channel 4b at a small gas flow, realizing the discharge of gas at a lower pressure.

[0049] As shown in Figure 11 , Figure 12 , the third state, the insertion end 1c is inserted into the exhaust gear groove 2f. At this time, the limiting block 5 abuts against the plugging part 3 and completely lifts the plugging part 3 upward. The air channel 4b is completely opened due to the lifting of the plug 3a, and the gas in the pressure cooker can be smoothly discharged to the outside through the air channel 4b, realizing the rapid pressure reduction operation under high pressure.

[0050] As shown in Figure 6As shown, the outer wall of the rotating piece 1 is provided with a positioning block 1b and a dial block 1a for dialing the rotating piece 1, the inner wall of the mounting seat 2 is provided with a limiting groove 2c, the positioning block 1b is arranged in the limiting groove 2c, and the rotating piece 1 is switched to different gear grooves, and the limiting groove 2c is synchronously rotated.

[0051] The outer wall of the mounting seat 2 is provided with a convex 2a for facilitating a user to judge the state of the regulating valve, and the rotating piece 1 is provided with symbols corresponding to different gear grooves, specifically, the symbols are "I", "II" and "III", wherein "II" corresponds to the high-pressure gear groove 2d, "I" corresponds to the low-pressure gear groove 2e, and "III" corresponds to the exhaust gear groove 2f, according to the convex 2a corresponding to different symbols, the user can intuitively understand the current working state of the pressure regulating valve, and the user operation is more convenient.

[0052] In the description of the utility model, it needs to be explained that the terms "upper", "lower", "front", "rear", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the utility model product is used, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.
