Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cookware, in particular to a pressure regulating valve structure with a simple structure and a cookware. Background Art
[0002] For existing cookware such as pressure cookers or rice cookers, a through hole is usually formed in the pot lid, and then a pressure regulating valve is inserted into the through hole. In order to fix the pressure regulating valve and ensure the sealing effect, the inner wall of the through hole is usually welded to the outer wall of the valve body of the pressure regulating valve. This method can form a good seal between the pressure regulating valve and the inner wall of the through hole to avoid affecting the sealing performance of the pot lid, thereby preventing the pot lid from prematurely releasing pressure before the internal pressure of the cookware reaches the expected value. However, the disadvantage is that it has high requirements for welding quality and is inconvenient to install. Summary of the Utility Model

[0029] Referring to Figures 1 to 4 , a pressure regulating valve structure with a simple structure according to the first aspect embodiment of the present utility model includes a valve cavity 110 formed on the pot lid 100, a fixed cover 200, a pressure regulating member 300, a valve rod 400, a pressure regulating spring 500, and a sealing piston 600. The top of the valve cavity 110 is open, and a valve hole 111 for pressure relief is provided on the bottom wall of the valve cavity 110; one end of the fixed cover 200 is inserted into the valve cavity 110 and is screwed to the inner wall of the valve cavity 110 through a coarse-threaded screw. The other end of the fixed cover 200 is provided with an exhaust hole 210 and a mounting hole 220. Both the exhaust hole 210 and the mounting hole 220 are communicated with the valve cavity 110, and the mounting hole 220 is disposed opposite to the valve hole 111; one end of the pressure regulating member 300 is inserted into the mounting hole 220 and is screwed to the inner wall of the mounting hole 220 through a fine-threaded screw. One end of the pressure regulating member 300 is provided with a jack 310, and the other end of the pressure regulating member 300 is provided with an operation part 320; the valve rod 400 is slidably inserted into the jack 310; the pressure regulating spring 500 is disposed in the jack 310. One end of the pressure regulating spring 500 abuts against the valve rod 400, and the other end abuts against the pressure regulating member 300; the sealing piston 600 is installed on the valve rod 400, and the sealing piston 600 presses and fits against the bottom wall of the valve cavity 110 and covers the valve hole 111.
[0030] Among them, when the cookware is working, the pressure regulating member 300 mainly bears the elastic force of the pressure regulating spring 500, and the fixed cover 200 bears the reaction force exerted by the pressure regulating member 300 and the air pressure during pressure relief. The fixed cover 200 bears a relatively large pressure. Therefore, in the present utility model, the fixed cover 200 is screwed to the inner wall of the valve cavity 110 through coarse-threaded threads, so that the fixed cover 200 can be reliably fixed in the valve cavity 110, effectively avoiding the situation that the fixed cover 200 is pushed open by the air pressure.
[0031] Among them, the pressure regulating member 300 is screwed to the inner wall of the mounting hole 220 through fine-threaded threads, which can make the adjustment precision of the pressure regulating member 300 higher. The user can rotate the pressure regulating member 300 by operating the operation part 320, thereby adjusting the elastic force exerted by the pressure regulating spring 500 on the valve stem 400.
[0032] For the pressure regulating valve structure provided by the present utility model, since the valve cavity 110 is directly formed on the pot lid 100, even if there is a gap between the fixed cover 200 and the inner wall of the valve cavity 110 or there are gaps between other components of the pressure regulating valve structure, the air flow during the exhaust of the cookware needs to pass through the valve hole 111 first before it can be discharged from these gaps. Therefore, only by sealing the piston 600 can the sealing performance between the entire pressure regulating valve structure and the pot lid 100 be effectively guaranteed, effectively avoiding the situation that the pot lid 100 has premature pressure relief due to the setting of the pressure regulating valve structure. Among them, when installing the pressure regulating valve structure, the fixed cover 200 can be screwed into the valve cavity 110. When installing the pressure regulating member 300, the pressure regulating member 300 can be screwed into the mounting hole 220. The valve stem 400 can be inserted into the insertion hole 310 of the pressure regulating member 300. The pressure regulating spring 500 can be arranged in the insertion hole 310. The sealing piston 600 can be installed on the valve stem 400. Thus, the pressure regulating valve structure provided by the present utility model does not need to be installed by welding, and components such as the fixed cover 200 and the pressure regulating member 300 can be disassembled and replaced later.
[0033] Refer to Figure 2 and Figure 4 According to some embodiments of the present utility model, a sealing ring 700 is arranged between the inner wall of the valve stem 400 and the insertion hole 310 to prevent air from entering the insertion hole 310 during the pressure relief process, prevent substances such as water vapor in the air from contacting the pressure regulating spring 500 and causing the working performance of the pressure regulating spring 500 to change, and improve the working life and reliability of the pressure regulating valve structure.
[0034] Refer to Figure 1 and Figure 2According to some embodiments of the present invention, a first concave hole 230 opposite to the valve hole 111 is provided at one end of the fixed cover 200, and the mounting hole 220 and the exhaust hole 210 are both connected to the first concave hole 230. By providing the first concave hole 230 on the fixed cover 200, more activity space can be provided for the sealing piston 600, the required length of the valve chamber 110 can be reduced, and the production consumables of the fixed cover 200 can be reduced.
[0035] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a second concave hole 410 is provided at one end of the valve column 400 away from the valve hole 111, and the pressure regulating spring 500 is inserted into the second concave hole 410. By providing the second concave hole 410 on the valve column 400, more activity space can be provided for the pressure regulating spring 500, the required length of the insertion hole 310 can be reduced, and the height of the pressure regulating member 300 can be reduced.
[0036] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a slot 420 is provided on one side of the valve column 400 facing the valve hole 111, and a portion of the sealing piston 600 is clamped in the slot 420. The above arrangement can facilitate the disassembly and assembly of the sealing piston 600.
[0037] Reference Figure 2 According to some embodiments of the utility model, the cross-section of the slot 420 is circular, and the diameter of the slot 420 gradually decreases from the bottom to the opening. The shape of the part of the sealing piston 600 inserted into the slot 420 is adapted to the slot 420, thereby, the sealing piston 600 can be securely connected to the valve column 400.
[0038] It should be noted that, in other embodiments, the sealing piston 600 may also be installed on the valve column 400 by means of threading, sleeve installation, etc.
[0039] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the size of the operating part 320 is larger than the mounting hole 220. Thus, a limiting effect can be formed by the cooperation between the operating part 320 and the inner wall of the mounting hole 220. Now the pressure regulating part 300 is screwed into the length range of the valve cavity 110.
[0040] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the operating portion 320 is provided with a heat insulating cover 800 to reduce the possibility of a user being burned when rotating the operating portion 320 .
[0041] Reference Figure 2 andFigure 4 In some embodiments, the operating part 320 is provided with a hollow hole 321 to further reduce the heat transfer effect of the operating part 320 on the heat insulation cover 800.
[0042] According to some embodiments of the present invention, the fixed cover 200, the pressure regulating part 300 and the valve stem 400 are all composed of at least one lathe - machined part with a cylindrical outer contour. With the above - mentioned arrangement, in the pressure regulating valve structure provided by the present invention, the fixed cover 200, the pressure regulating part 300, the valve stem 400, etc. can all be produced by lathe machining. These components have a simple shape, sufficient strength, better reliability and service life, while the pressure regulating spring 500 and the sealing ring 700 can be standard parts.
[0043] The cookware according to the second - aspect embodiment of the present invention includes the above - mentioned pressure regulating valve structure with a simple structure. In the specific implementation process, the cookware includes a pot lid 100 and a pot body. The pot lid 100 is detachably installed at the opening of the pot body to open and close the opening of the pot body. For the above - mentioned pressure regulating valve structure, its valve cavity 110 is directly formed on the pot lid 100, and the valve cavity 110 is communicated with the internal space of the pot body through a valve hole 111. Thus, during the working process of the cookware, before the internal pressure of the pot body reaches the expected value, the internal pressure of the pot body cannot push open the sealing piston 600, and the sealing piston 600 can close the valve hole 111, so that the high - pressure air inside the pot body will not leak from the pressure regulating valve. After the internal pressure of the pot body exceeds the expected value, the internal pressure of the pot body can push open the sealing piston 600, so that the valve hole 111 is opened for pressure relief.
[0044] By adopting the above - mentioned pressure regulating valve structure, the sealing performance between the entire pressure regulating valve structure and the pot lid 100 can be effectively guaranteed, and it can effectively avoid the situation that the pot lid 100 has premature pressure relief due to the setting of the pressure regulating valve structure. The pressure regulating valve structure does not need to be installed by welding, is convenient to install, and the components such as the fixed cover 200 and the pressure regulating part 300 can be disassembled, assembled and replaced later.
[0045] In the specific implementation process, the user can adjust the pressure reached inside the cookware by using the above - mentioned pressure regulating valve structure according to the food to be cooked, so as to make the cookware cook more delicious food. In addition, in different altitude areas, under the same pressure of the pressure regulating spring 500, the pressure that can be reached inside the cookware is different. The user can adjust according to the local altitude by using the above - mentioned pressure regulating valve structure so that the required pressure can be reached inside the cookware.
[0046] To facilitate users to adjust the pressure regulating valve structure according to actual situations, one of the fixed cover 200 and the pressure regulating member 300 is provided with a food list and the other is provided with an altitude scale. Among them, the foods in the food list are arranged according to the required cooking pressure, and the altitude scale is arranged according to the altitude. Moreover, the arrangement order of the food list is opposite to that of the altitude scale. In this way, when cooking different foods in different altitude areas, by rotating the pressure regulating member 300, the corresponding food name on the food list can be moved to the altitude scale corresponding to the local altitude, so that the desired pressure can be achieved inside the cookware.
[0047] In the specific implementation process, the elastic coefficient of the pressure regulating spring 500 will determine the rotation angle of the pressure regulating member 300. If the rotation angle of the pressure regulating member 300 is less than 360 degrees when the pressure is adjusted, the food list and the altitude scale are arranged in a circle. If the pressure regulating member 300 needs to rotate multiple circles when the pressure is adjusted, the altitude scale and the food list are arranged along the rotation axis of the pressure regulating member.
[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0049] The above has described this embodiment in detail with reference to the drawings. However, the present invention is not limited to the above embodiment, and various changes can be made without departing from the gist within the knowledge scope of those of ordinary skill in the art.
