Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to a pressure regulating valve and a pot cover. Background Art

[0002] Most of the electric rice cookers on the market currently use a fixed pressure regulation method, that is, a single pressure regulating valve is used to control the pressure in the pot. Although this design is simple and easy to use, it cannot meet the different pressure requirements of different ingredients. For example, some ingredients need to be cooked at a higher pressure to maintain their taste and nutrition, while other ingredients need to be cooked at a lower pressure to avoid overcooking or nutrient loss. Since the existing electric rice cookers do not have a multi-stage pressure regulating valve structure, it is impossible to achieve multi-stage pressure regulation for different ingredients during the cooking process. This results in the inability to flexibly adjust the pressure in the pot according to the characteristics of the ingredients and cooking needs during the cooking process, which affects the taste and nutrient retention of the ingredients.

[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-6 As shown, a pressure regulating valve includes a valve seat 1, an exhaust pipe 10, an exhaust channel 11, an inner valve body 2, an exhaust hole 20, a valve cover 3, a first sealing member 30, a groove 4, a boss 31, a second sealing member 5, a first step surface 101, a second step surface 102, a limiting flange 40, a guide groove 21, a buckle 22, a clamping ring 12, a first limiting groove 120, a limiting column 23, a fixing plate 6, a second limiting groove 60, a groove 13, an elastic ring 7, a cover body 8, a positioning ridge 80, and a positioning groove 14.

[0028] A pressure regulating valve comprises: a valve seat 1, which is sleeved on an exhaust pipe 10, the valve seat 1 having an exhaust passage 11, and the exhaust pipe 10 is passed through the exhaust passage 11;

[0029] The inner valve body 2 is sleeved on the valve seat 1 and has an exhaust hole 20 in the middle thereof which can communicate with the exhaust channel 11;

[0030] A valve cover 3 is sleeved on the inner valve body 2, and a first sealing member 30 for sealing the exhaust pipe 10 is provided in the middle corresponding to the exhaust pipe 10;

[0031] like Figure 1 , Figure 2As shown, the inner wall of the inner valve body 2 facing the exhaust pipe 10 is provided with a second sealing member 5, the outer wall of the inner valve body 2 is provided with a groove 4, and the inner wall of the valve cover 3 is provided with a boss 31 that can move along the groove 4 corresponding to the groove 4. When the valve cover 3 rotates around the axial direction of the exhaust pipe 10 and climbs upward along the groove 4, the valve cover 3 drives the inner valve body 2 to press down the second sealing member 5, so that the second sealing member blocks the exhaust pipe 10. By setting the first sealing member and the second sealing member, when the valve cover rotates clockwise to the end, the boss moves toward the bottom along the groove, the valve cover moves in the direction close to the valve seat, and the first sealing member moves in the direction away from the first step surface. The valve cover drives the inner valve body to press down the second sealing member by its own weight, and the second sealing member blocks the second step surface. Through multi-stage pressure regulation, the cooking process of the food can be better controlled, and the pressure inside the rice cooker can be flexibly adjusted according to the cooking requirements of different food materials, thereby achieving better cooking effects.

[0032] Preferably, the exhaust pipe 10 has a first step surface 101 and a second step surface 102 which are sequentially arranged corresponding to the first seal 30 and the second seal 5. When the valve cover 3 rotates counterclockwise around the exhaust pipe 10, the first seal 30 moves in a direction away from the first step surface 101, and the second seal 5 blocks the second step surface 102. The arrangement of the first step surface and the second step surface enables the first seal and the second seal to respectively contact or separate from the corresponding step surfaces at different rotation angles. Through such a design, multi-stage adjustment of the internal pressure of the rice cooker can be achieved to meet the cooking requirements of different ingredients. More preferably, the cross-sectional area of ​​the first seal 30 is smaller than the cross-sectional area of ​​the second seal 5.

[0033] Preferably, if Figure 3 , Figure 4 As shown, the groove 4 meanders from bottom to top along the outer wall of the inner valve body 2 in a spiral winding shape, so that the boss of the inner wall of the valve cover can rise along the groove in a spiral, thereby increasing the stability of the graded pressure regulation.

[0034] Preferably, a limiting flange 40 for limiting the boss 31 is provided in the groove 4. When the valve cover 3 rotates around the exhaust pipe 10 axially and climbs along the groove 4, the limiting flange 40 can limit the boss 31 to keep the second sealing member 5 blocking the second step surface 102. The limiting flange cooperates with the boss to limit the movement range of the valve cover in the groove, thereby ensuring that the valve cover does not move excessively during the rotation process. This design ensures that the seal can continue to maintain close contact with the step surface to avoid leakage caused by improper position.

[0035] Preferably, the outer wall of the inner valve body 2 is provided with a guide groove 21 for the boss 31 to slide downward, and the guide groove 21 is connected with the end of the groove 4, so that the boss 31 can slide into the groove 4 through the guide groove 21. During the process of the valve cover rotating and climbing along the groove, the limiting flange can effectively keep the second sealing member tightly sealing the second step surface, and the valve cover's own weight will press the inner valve body downward. This reliable sealing ensures that gas or liquid will not leak at will, improves the safety of the system, and the design of the limiting flange enhances the connection stability between the valve cover and the exhaust pipe. Under extreme working conditions such as high pressure or high temperature, it can effectively prevent the position of the valve cover from being offset due to vibration or other factors, thereby further ensuring the performance of the valve. By controlling the range of motion of the valve cover, it can effectively reduce wear and fatigue, thereby extending the service life of the overall component.

[0036] Preferably, a buckle 22 is provided on the inner wall of the inner valve body 2, and a snap ring 12 for snapping the buckle 22 is provided on the valve seat 1 corresponding to the buckle 22, and a first limiting groove 120 is also provided on the snap ring 12. A limiting column 23 that can be inserted into the first limiting groove 120 is provided on the inner wall of the inner valve body 2 corresponding to the first limiting groove 120. This buckle design allows a safe and stable connection to be established between the valve seat and the inner valve body to prevent the valve body from loosening or falling off during operation. The design of the snap ring 12 enables the buckle 22 to be accurately inserted and snapped thereon, ensuring the fit between the valve seat and the inner valve body, thereby avoiding potential leakage problems or functional failures. The cooperation between the limiting column 23 and the first limiting groove 120 can prevent the valve seat from being displaced during installation or operation, thereby protecting the overall structure of the valve and ensuring its reliability during use. This design not only improves the safety of the valve, but also helps to simplify the maintenance and replacement process. Through this clamping and limiting design, the user can quickly and conveniently disassemble or install the valve assembly when performing daily inspection or replacing parts, reducing maintenance time and cost. More preferably, Figure 2 As shown, there is a gap between the inner valve body 2 and the valve seat 1. When the valve cover rotates counterclockwise to the end, the inner valve body can be pressed down to abut against the valve seat. At the same time, the second sealing member can be sealed on the second step surface of the exhaust pipe.

[0037] Preferably, the second sealing member 5 is arranged on the lower side of the inner valve body 2 through a fixed disk 6, and a second limiting groove 60 is provided on the circumferential side of the fixed disk 6 corresponding to the limiting column 23, through which the limiting column 23 can pass. The setting of the fixed disk 6 can provide support and a stable installation foundation for the second sealing member 5, and the circumferential side of the fixed disk 6 is provided with a second limiting groove 60, so that the limiting column 23 can pass freely. This design allows the limiting column 23 to move to a certain extent when necessary, thereby avoiding the influence of expansion or contraction caused by temperature changes or pressure changes on the seal.

[0038] Preferably, a groove 13 is provided in the valve seat 1 at one end close to the exhaust pipe 10, and an elastic ring 7 is embedded in the groove 13. The elastic ring 7 can be sleeved on the exhaust pipe 10. The elastic ring is provided to facilitate daily taking and disassembly by the user.

[0039] like Figure 5 , 6 As shown, a pot cover comprises a pressure regulating valve, a cover body 8 and an exhaust pipe 10, wherein the air inlet end of the exhaust pipe 10 is connected to the pot cover, and the air outlet end of the exhaust pipe 10 is passed through the exhaust channel 11 of the pressure regulating valve.

[0040] Preferably, the cover body 8 is provided with a positioning ridge 80, and the pressure regulating valve is provided with a positioning groove 14 corresponding to the positioning ridge 80. When the pressure regulating valve is sleeved on the exhaust pipe 10, the positioning ridge 80 cooperates with the positioning groove 14 to facilitate the positioning and clamping of the valve seat, and the valve cover facilitates the rotation of the air pressure.
