[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] like Figure 1 As shown, a check valve assembly in one embodiment of the present invention includes a check valve body, which is installed on the lid of a pressure cooker. When the pressure inside the pressure cooker is too high, the check valve body opens to release gas and reduce pressure in the pressure cooker.

[0026] Specifically, such as Figure 1 As shown, the check valve body includes a valve core 1, on which a first vent hole 101 is provided. A limiting seat 2 is fixedly connected to the lower part of the first vent hole 101, and a nut 3 is threadedly connected to the lower end of the valve core 1 located on the limiting seat 2. In use, the part of the valve core 1 located on the lower end of the limiting seat 2 is passed through the pressure cooker lid, and then the nut 3 is screwed onto the lower end of the valve core 1 located on the limiting seat 2 to complete the fixation of the pressure cooker lid and the valve core 1.

[0027] like Figure 1 As shown, a valve cover 4 is fitted onto the valve core 1. The valve cover 4 has multiple second vent holes 401, and a sealing part 5 is fixedly connected to the inner wall of the valve cover 4. The sealing part 5 can completely block the first vent hole 101. When the pressure inside the pressure cooker is high, the high-pressure gas can push the first vent hole 101 out of the sealing part 5, forming a pressure relief channel between the valve cover 4 and the valve core 1. The high-pressure gas is discharged from the pressure relief channel and can also be discharged from the second vent holes 401, thus completing the discharge of the high-pressure gas.

[0028] Among them, such as Figures 1-2As shown, a conical surface 501 is provided at one end of the sealing part 5 near the first vent hole 101. By providing the conical surface 501, even if the valve cover 4 is offset, the conical surface 501 can still enter the first vent hole 101, which facilitates the connection between the sealing part 5 and the first vent hole 101. A right-angled surface 502 is provided on the sealing part 5 to match the valve core 1. The right-angled surface 502 makes perfect contact with the first vent hole 101, which can improve the sealing performance of the check valve body in the non-venting state.

[0029] To reduce the safety hazards caused by the exhaust valve assembly during the exhaust process, such as Figure 1 As shown, a protective shell 6 is fixedly connected to the outside of the valve core 1, and an elastic bladder 7 is fixedly connected to the upper end of the protective shell 6. The protective shell 6 and the elastic bladder 7 work together to form a pressure relief space. That is, the gas discharged from the check valve body is first sprayed into the pressure relief space and then discharged from the pressure relief space. The high pressure gas can be depressurized before being discharged, so as to avoid the situation where the pressure is directly discharged and causes harm to people as much as possible.

[0030] Specifically, such as Figure 3 As shown, the elastic bladder 7 has multiple third vent holes 701, through which gas in the pressure relief space can eventually be discharged. A protrusion 12 is also fixedly connected to the elastic bladder 7, and a connecting strap 13 is fixedly connected to the protrusion 12. A second sealing cap 11 is fixedly connected to the end of the connecting strap 13 away from the protrusion 12. The second sealing cap 11 can completely seal the third vent holes 701, preventing gas from being discharged from the third vent holes 701.

[0031] like Figure 1 As shown, multiple heat sinks 14 are fixedly connected to the protective shell 6, and multiple baffles 402 are fixedly connected to the valve cover 4. There is a gap between the baffles 402 and the heat sinks 14. After the high-pressure gas is discharged from the check valve body, it will first contact the heat sinks 14, and then contact the baffles 402. After contacting multiple heat sinks 14 and baffles 402, the impact force of the high-pressure gas can be greatly reduced, reducing the possibility of high-pressure gas directly spraying out and causing injury to the human body. In addition, impurities accompanying cooking are likely to remain at the angle between the heat sinks 14 and the baffles 402 during the contact process, reducing the possibility of impurities in the discharged gas and reducing the mess on the stove due to the use of a pressure cooker.

[0032] like Figure 1 As shown, a waste discharge port 15 is fixedly connected to the bottom of the protective shell 6, through which impurities in the pressure relief space can be discharged. In use, the waste discharge port 15 is generally opened, and then water is added to the pressure relief space to clean the equipment inside the pressure relief space. The cleaned impurities are discharged from the waste discharge port 15.

[0033] like Figure 1As shown, an exhaust port 8 is fixedly connected to one side of the protective shell 6. A flexible hose can be connected to the exhaust port 8, and a cover can be installed at the other end of the hose. Hot air passes through the exhaust port 8, the hose, and the cover, and is finally discharged from the cover, which can cover the food. When used in cold environments, the hot air generated by the pressure cooker is used to keep the food warm, slowing down the cooling rate of the cooked food during the cooking process, which is energy-saving and environmentally friendly.

[0034] like Figure 1 As shown, a first sealing cover 9 is detachably installed on the exhaust port 8. When the heat generated by the pressure cooker is not needed, the first sealing cover 9 seals the exhaust port 8, and the heat is also discharged from the third exhaust hole 701.

[0035] To further reduce the possibility of blockage at the exhaust port 8, a filter screen 10 is fixedly connected to one side of the exhaust port 8, and the filter screen 10 is fixedly connected to the inner wall of the protective shell 6. The gas passes through the filter screen 10 and then through the exhaust port 8, where the filter screen 10 filters impurities in the gas.

[0036] In use, first install the check valve assembly on the pressure cooker lid. The general procedure is to insert the end of the limiting seat 2 away from the protective shell 6 through the pressure cooker lid and tighten it with the nut 3 to secure the pressure cooker lid and the check valve assembly. When the check valve assembly releases gas, the high-pressure gas first exits from the check valve body and is sprayed onto the inner wall of the protective shell 6. Because the pressure relief space is under high pressure, the high-pressure gas in the pressure relief space will move towards the third vent 701. During this movement towards the third vent 701, the high-pressure gas continuously contacts the baffle 402 and the heat sink 14, further reducing the impact force of the high-pressure gas and blocking some impurities, reducing the likelihood of impurities in the gas being ejected from the third vent 701.

[0037] When there are too many impurities in the pressure relief space, the waste outlet 15 can be opened to add water to the pressure relief space for rinsing. After rinsing, the impurities and water can be discharged from the waste outlet 15.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
