Technical Field
[0001] This utility model is a pressure limiting component for a pressure cooker, belonging to the field of pressure cooker technology. Background Technology
[0002] A pressure cooker, also known as a pressure cooker, is a type of kitchen cookware. Pressure cookers utilize the physical phenomenon that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus speeding up the cooking process. It can heat food to over 100°C. In high-altitude areas, pressure cookers can prevent the problem of water's boiling point lowering and food becoming difficult to cook thoroughly.
[0003] Publication number CN221060374U mentions a pressure-limiting valve for a pressure cooker. By setting the mating hole to one of various shapes and setting the shape of the mating part to be the same, the valve body and the plastic inner core can be circumferentially fixed. Moreover, the various shapes mentioned above can be directly punched into the valve body using a punching machine with the corresponding shaped punch, making production very convenient. However, during the use of this device, the valve body needs to be opened, and the pressure cooker releases steam through the gap. But during the steam release process, oil, water, and steam are sprayed onto the user's hands, and the position of the steam spray cannot be controlled. There is an urgent need for a pressure-limiting component for pressure cookers to solve the above-mentioned problems. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1-5 This utility model provides a technical solution: a pressure cooker pressure limiting component, including a pressure relief valve 1 and a threaded pipe 3. The pressure relief valve 1 has a threaded rod 7 inside its thread. A spring 8 is fixedly connected to the circular groove of the threaded rod 7. A sliding rod 9 is fixedly connected to the lower end of the spring 8. The sliding rod 9 is slidably connected to the circular groove of the threaded rod 7. A fixing block 11 is fixedly connected to the lower end of the sliding rod 9. A sealing head 13 is fixedly connected to the lower end of the fixing block 11. Two connecting pipes 6 are fixedly connected through and through the circumferential surface of the pressure relief valve 1. One end of each connecting pipe 6 is rotatably connected to an adjusting spray pipe 4. This design solves the problem that in the original device, the valve body needs to be opened during use, and the pressure cooker releases steam through the gap. However, during the steam release process, oil, water, and steam will spray onto the user's hands, and the position of the steam spray cannot be controlled.
[0022] As the first embodiment of this utility model: A rotating rod 2 is fixedly connected to the upper end of the threaded rod 7. The circumferential surface of the rotating rod 2 is provided with a concave-convex layer. The rotating rod 2 installed on the threaded rod 7 allows the user to unscrew it. The concave-convex layer on the surface of the rotating rod 2 increases the friction between the rotating rod 2 and the user's hand, making it less likely to slip when the user rotates the rotating rod 2. A limiting ring 10 is fixedly connected to the lower end of the threaded rod 7. The limiting ring 10 installed at the lower end of the threaded rod 7 can be used to limit the fixed block 11. When steam is ejected, it will push the fixed block 11 to move upward, and at the same time, the limiting ring 10 can limit the fixed block 11, so that the steam can be discharged through the connecting pipe 6. A first sealing ring 12 is provided between the fixed block 11 and the threaded pipe 3. The first sealing ring 12 is made of rubber material. The first sealing ring 12 installed in the threaded pipe 3 and the fixed block 11 can increase the sealing performance of the fixed block 11. The first sealing ring 12 is made of rubber, which can increase its plasticity and sealing area. Adjusting plates 5 are fixedly connected to the lower ends of both adjusting nozzles 4. The two adjusting plates 5 are made of heat-insulating material and are installed at the lower ends of the adjusting nozzles 4 to prevent users from being scalded by steam inside the adjusting nozzles 4 when adjusting their direction. The heat-insulating material also prevents steam from escaping through the adjusting plates 5. Second sealing rings 14, made of rubber, are installed between the two adjusting nozzles 4 and the two connecting pipes 6. These second sealing rings 14 increase the sealing performance between the connecting pipes 6 and the adjusting nozzles 4, thus preventing leakage during steam discharge from the adjusting nozzles 4.
[0023] As a second embodiment of this utility model: First, the threaded pipe 3 is fixedly connected inside the pressure cooker. When using the pressure cooker, the fixed block 11 can be moved downward by rotating the rotating rod 2, so that the sealing head 13 blocks the air vent of the pressure cooker. After using the pressure cooker, the fixed block 11 can be moved upward by rotating the rotating rod 2, so that the threaded pipe 3 is connected to the two connecting pipes 6. Then, the angle of the spray pipe 4 is adjusted to avoid the steam sprayed from the connecting pipes 6 from affecting the user.
[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model 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 basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
