DETAILED DESCRIPTION

[0024] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0025] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0026] Example:

[0027] like Figures 1 to 3 As shown, a pressure cooker cover comprises a body 11 and an exhaust valve 12 arranged on the body 11, the body 11 comprises an inner cover 111 and an outer cover 112, an installation space 113 is formed between the inner cover 111 and the outer cover 112, the exhaust valve 12 is penetrated on the inner cover 111 and partly located in the installation space 113; the exhaust valve 12 has an air inlet 1212 and an air outlet 1211, when the outer cover 112 is installed to the inner cover 111, the outer cover 112 shields the exhaust valve 12, and the outer cover 112 is provided with an air outlet hole 1121 connected with the air outlet 1211.

[0028] In this embodiment, a pressure cooker cover 1 is provided which is covered with a pot body 2 of a pressure cooker. After the pot body 2 and the pot cover 1 are combined, a sealed space for cooking can be formed, so that the boiling point of water is increased, and the cooking efficiency is greatly improved. The pot cover 1 includes a body 11 and an exhaust valve 12 arranged on the body 11. The body 11 includes an inner cover 111 and an outer cover 112 which cooperate with each other. The outer cover 112 covers the outer side of the inner cover 111, and an installation space 113 for installing the exhaust valve 12 is formed between the inner cover 111 and the outer cover 112. The exhaust valve 12 has an air inlet 1212 and an air outlet 1211. The water vapor in the pot body 2 enters the exhaust valve 12 from the air inlet 1212, and then discharges the exhaust valve 12 from the air outlet 1211, so that the pressure in the pot body 2 is reduced, and it is convenient to open the cover after cooking. When the outer cover 112 is installed on the inner cover 111, the outer cover 112 can cover the exhaust valve 12 to hide the exhaust valve 12. The outer cover 112 is provided with an exhaust hole 1121 that is connected to the exhaust port 1211 and has a corresponding position, that is, the exhaust hole 1121 is arranged above the exhaust valve 12, so that the exhaust hole 1121 can quickly discharge the water vapor in the pot body 2. The exhaust valve 12 is penetrated on the inner cover 111 and partially located in the installation space 113, so that the exhaust valve 12 can be protected by the inner cover 111 and the outer cover 112 when working. The exhaust valve 12 has an air inlet 1212 and an air outlet 1211, which allows the steam or gas in the pot to be discharged when the pressure reaches a certain level, thereby preventing the danger caused by excessive pressure.

[0029] The pressure cooker cover 1 of this embodiment, by setting the exhaust valve 12 on the inner cover 111 and shielding the exhaust valve 12 with the outer cover 112, the exhaust valve 12 is hidden in the cover 1, which does not damage the appearance of the outer surface of the pressure cooker cover 1, improves the aesthetics of the pressure cooker cover 1 and the pressure cooker, and can also increase the volume of the exhaust valve 12 without worrying about affecting the appearance, thereby enhancing the anti-overflow function. In addition, the hidden setting of the exhaust valve 12 can also avoid causing fear to the user during use, and improve the user experience.

[0030] The exhaust valve 12 includes a valve seat 121 and a valve core 122 arranged in the valve seat 121. The air inlet 1212 and the air outlet 1211 are both formed on the valve seat 121. The valve core 122 has a first position blocking the air inlet 1212 and the air outlet 1211 and a second position connecting the air inlet 1212 and the air outlet 1211.

[0031] The exhaust valve 12 includes a valve seat 121 and a valve core 122. The valve seat 121 is a fixed part of the exhaust valve 12. The valve seat 121 carries the valve core 122 and provides a structural basis, while the valve core 122 is a movable part that can move in the valve seat 121. The valve core 122 can control the on-off between the air inlet 1212 and the air outlet 1211 by moving. The air inlet 1212 is formed at the bottom end of the valve seat 121, and the air outlet 1211 is formed at the top end of the valve seat 121. In the first position, the valve core 122 abuts against the air inlet 1212 to close the air inlet 1212 to block the air inlet from being connected to the air outlet 1211. In the second position, the valve core 122 leaves the air inlet 1212 to connect the air outlet 1211 with the air inlet 1212.

[0032] The valve core 122 is constructed as a ball valve. The inner wall of the valve seat 121 is formed with a pressing block 1213 protruding toward the valve core 122. When the pressure exerted on the pressing block 1213 toward the valve core 122 exceeds a preset value, the pressing block 1213 drives the valve core 122 to move from the first position to the second position.

[0033] In the present embodiment, the valve core 122 is constructed as a ball valve made of metal material and has a certain weight. The wall thickness of the pressing block 1213 is greater than the wall thickness of the valve seat 121, that is, the pressing block 1213 protrudes toward the valve core 122. When the pressure on the pressing block 1213 toward the valve core 122 exceeds the preset value, this pressure will push the pressing block 1213 to move, and then drive the valve core 122 from the first position (i.e., the position blocking the air inlet 1212 and the air outlet 1211) to the second position (i.e., the position connecting the air inlet 1212 and the air outlet 1211). It should be noted that the pressure on the pressing block toward the valve core 122 proposed here should be mechanical pressure. There are many mechanical structures that can achieve this effect, such as using a push rod or a connecting rod, etc., which will not be repeated here.

[0034] One end of the pressing block 1213 away from the valve core 122 protrudes from the outer wall of the valve seat 121 .

[0035] In this embodiment, one end of the pressing block 1213 away from the valve core 122 also protrudes from the outer wall of the valve seat 121, that is, both ends of the pressing block 1213 protrude from the side wall surface of the valve seat 121, so that the mechanical structure outside the valve seat 121 can more accurately act on the pressing block 1213. In other embodiments, the pressing block 1213 can also only protrude toward the valve core 122 relative to the inner wall surface of the valve seat 121.

[0036] The valve seat 121 is constructed as a flexible silicone block. When the pressure exerted on the pressing block 1213 toward the valve core 122 exceeds a preset value, the side wall of the valve seat 121 is deformed so that the pressing block 1213 drives the valve core 122 to move.

[0037] In the present embodiment, the pressing block 1213 and the valve seat 121 are an integrated structure, and silicone is a soft, elastic and temperature-resistant material. Selecting silicone as the material of the valve seat 121 means that when the exhaust valve 12 is subjected to pressure, the side wall of the valve seat 121 can be deformed, and then the valve core 122 is driven to move by the pressing block 1213. Of course, the valve seat 121 can also be made of other materials with deformation ability such as rubber. In other embodiments, the pressing block 1213 and the valve seat 121 can also be a split structure, that is, the pressing block 1213 can move relative to the valve seat 121, and in this case, the pressing block 1213 does not have to be made of a material with deformation ability.

[0038] The inner surface of the valve seat 121 has at least one air outlet notch 1214 opened along the height direction of the valve seat 121 , and a gap is formed between the air outlet notch 1214 and the valve core 122 .

[0039] The size of the valve core 122 is close to the size inside the valve seat 121 to improve the sealing between the air inlet 1212 and the air outlet 1211 when the valve core 122 is in the blocking position, and prevent the valve core 122 from leaving the air inlet 1212 due to shaking. In order to ensure that the air inlet 1212 and the air outlet 1211 are connected when the valve core 122 is in the second position, the inner surface of the valve seat 121 is provided with an air outlet notch 1214 along its own height direction, and there is a gap for air outlet between the air outlet notch 1214 and the valve core 122. The number and size of the air outlet notch 1214 can be designed according to the specific flow demand and pressure requirement. Multiple air outlet notches 1214 can provide a larger flow area, and a larger air outlet notch 1214 can allow a larger flow to pass through.

[0040] like Figure 3 and Figure 4 As shown, a sealing sheet 1215 for sealing the installation space 113 is provided on the side of the valve seat 121 facing the outer cover 112 .

[0041] In this embodiment, a sealing sheet 1215 is provided on the side of the valve seat 121 facing the outer cover 112. The sealing sheet 1215 cooperates with the outer cover 112 to seal the installation space 113, prevent water vapor from carrying impurities into the installation space 113, and avoid the installation space 113 from harboring dirt. The sealing sheet 1215 is usually made of a soft, elastic and corrosion-resistant material, such as rubber, silicone or a special synthetic material. These materials have good sealing and durability, and can maintain stable performance in various environments. The sealing sheet 1215 is usually fixed to the outer cover 112 by pressing, pasting or embedding. During the installation process, it is necessary to ensure that the contact surface of the sealing sheet 1215 and the outer cover 112 fits tightly without gaps or bubbles to ensure a good sealing effect.

[0042] An accommodating groove 1122 is formed on the inner wall of the outer cover 112 along the thickness direction. The valve seat 121 extends into the accommodating groove 1122 at one end facing the outer cover 112 , and the outer edge of the sealing sheet 1215 is embedded in the groove wall of the accommodating groove 1122 .

[0043] The inner wall surface of the outer cover 112 is provided with a receiving groove 1122 along its thickness direction, and the receiving groove 1122 is used to accommodate one end of the valve seat 121 and ensure that the outer edge of the sealing sheet 1215 can be embedded in the groove wall of the receiving groove 1122, thereby ensuring a close fit between the sealing sheet 1215 and the receiving groove 1122, thereby enhancing the overall sealing performance.

[0044] A valve hole is formed on the inner cover 111 , and an annular groove which is clamped in the valve hole is formed on the exhaust valve 12 .

[0045] An annular groove is formed on the exhaust valve 12 and is engaged with the valve hole, so that the exhaust valve 12 and the valve hole are closely matched. When the exhaust valve 12 is placed on the inner cover 111, the annular groove is engaged with the valve hole to form a stable connection. In addition to stable installation, the annular groove can also enhance the sealing between the exhaust valve 12 and the inner cover 111. When the two are closely matched, the contact area between the exhaust valve 12 and the inner cover 111 is increased, reducing the possibility of leakage.

[0046] This embodiment further provides a pressure cooker, comprising a cooker body 2 and a cooker cover 1, wherein the cooker cover 1 comprises the aforementioned pressure cooker cover 1.

[0047] The pot body 2 is the main part of the pressure cooker, which is usually made of stainless steel or aluminum alloy, has high strength and corrosion resistance, and can withstand high pressure and high temperature. In addition to the exhaust valve 12 on the pot cover 1, the pot cover 1 may also be equipped with other safety devices, such as overheating protection devices or pressure sensors, to monitor the temperature and pressure in the pot in real time and take safety measures when necessary.

[0048] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention shall be included in the scope of the claims.
