Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and relates to a pressure relief valve, particularly a pressure cooker pressure relief valve. Background Technology

[0002] Pressure cookers, as highly efficient cooking appliances, are favored by consumers for their ability to quickly tenderize and flavor food. Through their sealed design, they create a high-pressure environment inside the pot, raising the boiling point of water and accelerating cooking. However, as the pressure inside the pot increases, if excess pressure is not released in time, it can lead to serious safety hazards, such as the pot exploding, posing a significant threat to the personal safety and property of the user. Therefore, the pressure relief valve, as a key safety component of the pressure cooker, directly affects the safety and reliability of its use.

[0003] Traditional pressure relief valves mostly lack effective pressure indication functions, making it difficult for users to intuitively understand the specific changes in pressure inside the pot. During use, users can only rely on experience to judge whether the pressure inside the pot is approaching a dangerous value, and cannot accurately grasp the pressure dynamics, which brings a certain degree of blindness and safety hazards to use; the valve core lacks effective guiding and limiting structures during movement, and is prone to shaking and deviation; traditional pressure relief valves have limited ability to handle air intake blockage problems. Once the air intake chamber is blocked, the pressure inside the pot cannot be released in time through the normal exhaust channel, which will lead to abnormal pressure accumulation and increase the risk of explosion. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a pressure relief valve for a pressure cooker. This reduces the requirements for the pressure cooker body, lid, and sealing ring, ensuring the stability and high safety of the pressure cooker during pressure relief.

[0005] The objective of this utility model can be achieved through the following technical solution: a pressure cooker pressure relief valve, comprising a valve body and a valve core, characterized in that a sealing groove is provided between the valve body and the valve core, and an elastic structure with a sealing function is provided in the sealing groove; a fixed seat is fitted inside the valve body to limit and abut the elastic structure; an indicator component with an indicating function is provided on the valve core; multiple exhaust structures with exhaust function are provided on the valve body; and several anti-blocking structures with anti-blocking function are provided on the fixed seat.

[0006] In the pressure relief valve of the pressure cooker described above, the indicating component and the valve core are integrally formed.

[0007] In the pressure relief valve of the pressure cooker described above, the indicating component and the valve core are separate components, and the indicating component is fixed to the valve core by a fixing component.

[0008] In the aforementioned pressure cooker pressure relief valve, the fixing component includes a retaining ring formed on the indicating component, and the valve core has a retaining groove into which the retaining ring engages.

[0009] In the pressure relief valve of the pressure cooker mentioned above, the exhaust structure adopts an elliptical exhaust hole or a round hole exhaust hole.

[0010] In the pressure relief valve of the pressure cooker mentioned above, the anti-clogging structure adopts a straight anti-clogging groove, a cross-shaped anti-clogging groove, or a star-shaped anti-clogging groove.

[0011] In the pressure relief valve of the pressure cooker described above, a fastener is threadedly connected to the valve body, and a gap groove is provided between the fastener and the valve body.

[0012] In the aforementioned pressure cooker pressure relief valve, a sealing ring is provided on the valve body.

[0013] Working Principle: During normal use of the pressure cooker, as the pressure inside the pot gradually increases, gas enters the valve body. When the pressure reaches a certain value, the upward thrust of the gas on the valve core overcomes the weight of the valve core and the resistance of the locking structure, causing the valve core to move upward along the sliding through hole. As the valve core moves, the indicating component also rises, allowing the user to understand the pressure inside the pot by observing the position change of the indicator. When the valve core rises to a certain position, the gas inside the pot is quickly discharged through the venting structure, achieving the purpose of pressure relief. As the pressure inside the pot decreases, pressing the valve core downward fixes it onto the elastic structure, restoring the sealing state, closing the venting passage, and the pressure cooker returns to normal operation. Throughout the entire process, the elastic structure ensures the sealing performance of the pressure cooker, and the anti-clogging structure prevents impurities from blocking the gas passage, ensuring that the pressure relief valve can work stably and reliably. Throughout the entire operation, if blockage occurs on the plane, the airflow can smoothly enter the valve body through the uniquely designed anti-blockage groove, ensuring the smooth flow of the pressure relief valve. By installing a fixed seat at the bottom of the elastic structure to ensure its stability and prevent the elastic structure from falling off, the reliability and safety of the pressure relief valve are guaranteed.

[0014] Compared with existing technologies, the pressure relief valve of this pressure cooker has the following advantages: 1. The detachable snap-fit ​​structure design not only greatly reduces the difficulty of maintenance and the time and labor costs required for maintenance, but also effectively avoids unnecessary damage to other intact parts due to excessive disassembly, thereby extending the overall service life of the pressure relief valve.

[0015] 2. The top of the valve core is equipped with an indicator component with an indication function. By accurately indicating the pressure, users can avoid damage to the pressure cooker caused by excessive or insufficient pressure.

[0016] 3. By providing an anti-clogging groove at the bottom of the fixed seat, when the air intake plane of the fixed seat becomes blocked due to the accumulation of impurities, the originally obstructed airflow can quickly and smoothly enter the valve body through this anti-clogging groove, effectively avoiding abnormal pressure accumulation caused by blockage, greatly improving the safety and stability of the entire pressure relief system under complex working conditions, and ensuring that the pressure relief function can be continuously and stably performed.

[0017] 4. It ensures the stability of the pressure cooker during pressure release, resulting in high safety.

[0018] 5. The elastic structure of the sealing function improves the sealing between the pressure relief valve and the lid, thus enhancing the performance of the pressure cooker. Attached Figure Description

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] like Figures 1 to 12 As shown, this pressure cooker pressure relief valve includes a valve body 1 and a valve core 2. A sealing groove 3 is located between the valve body 1 and the valve core 2, and an elastic structure 4 with a sealing function is provided within the sealing groove 3. The elastic structure 4 can be made of a rubber sealing ring. Rubber material has good elasticity and sealing performance, and can form a reliable seal between the valve body 1 and the valve core 2, preventing gas leakage from the pressure cooker in a non-pressure-relief state. A fixing seat 5 is fitted inside the valve body 1 to limit and abut the elastic structure 4. The fixing seat 5 firmly supports the elastic structure 4 from bottom to top, providing reliable support for the elastic structure 4. An indicator group with an indicating function is provided on the valve core 2. Component 6, the indicator component 6 is made of red material. When the pressure is discharged upward along the valve body 1, the user can intuitively understand the pressure change inside the pressure cooker by observing the position change of the indicator component 6, which serves as a pressure indicator. The valve body 1 has multiple exhaust structures 7 with exhaust function, and the fixed seat 5 has several anti-blocking structures 8 with anti-blocking function. The function of the anti-blocking structure 8 is that when the air inlet plane of the fixed seat 5 is blocked due to the accumulation of impurities, the originally obstructed airflow can quickly enter the valve body 1 smoothly through this anti-blocking structure 8, effectively avoiding abnormal pressure accumulation caused by blockage.

[0034] like Figure 7 As shown, the indicator component 6 and the valve core 2 are integrally molded. The integral molding structure is simple to manufacture, which can reduce the number of parts and reduce production costs.

[0035] like Figure 8 As shown, the indicator component 6 and the valve core 2 are separate units. The indicator component 6 is fixed to the valve core 2 by the fixing component 9. The separate structure makes it easy to replace and maintain the indicator component 6. When the indicator component 6 is damaged, it can be simply removed from the valve core 2 and replaced with a new indicator component 6.

[0036] To elaborate further, the fixing component 9 includes a retaining ring 10 formed on the indicating component 6, and the valve core 2 has a retaining groove 11 for the retaining ring 10 to be engaged. During installation, the retaining ring 10 on the indicating component 6 is aligned with the retaining groove 11 on the valve core 2, and the indicating component 6 is fixed to the valve core 2 by pressing it firmly.

[0037] To elaborate further, the exhaust structure 7 uses either an elliptical or a round exhaust port. Both elliptical and round exhaust ports can effectively expel gas from the pressure cooker, achieving a pressure relief function. Compared to round exhaust ports, elliptical exhaust ports have a larger exhaust area for the same area, thus improving exhaust efficiency. Round exhaust ports are simpler to manufacture and have lower costs. Users can choose different shapes of exhaust ports according to their actual needs.

[0038] To elaborate further, the anti-clogging structure 8 adopts a straight anti-clogging groove 12, a cross-shaped anti-clogging groove 13, or a star-shaped anti-clogging groove 14. The anti-clogging structure 8 is set as a straight, cross-shaped, or star-shaped anti-clogging groove 14. By changing the flow path of airflow and impurities, it can effectively prevent impurities from accumulating in the exhaust channel, thereby reducing the risk of blockage. Among them, the straight anti-clogging groove 12 has a simple structure, is easy to manufacture, and has a low cost.

[0039] To elaborate further, a fastener 15 is threadedly connected to the outside of the valve body 1. A gap groove 16 is provided between the fastener 15 and the valve body 1. The fastener 15 is used to securely install the valve body 1 onto the pressure cooker. The pressure cooker lid is fixedly installed by the thread in the gap groove 16. The thickness of the lid is between 1.0-1.2mm.

[0040] To elaborate further, a sealing ring 17 is provided on the valve body 1. The function of the sealing ring 17 is to enhance the sealing performance between the valve body 1 and the pressure cooker, and to prevent gas in the pressure cooker from leaking from the connection between the valve body 1 and the pressure cooker. During installation, the sealing ring 17 is placed on the corresponding position on the valve body 1, and then the valve body 1 is installed on the pressure cooker. The sealing ring 17 is compressed by tightening the fasteners 15, thereby forming a reliable seal.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0042] Although this document frequently uses terms such as valve body 1, valve core 2, sealing groove 3, elastic structure 4, fixing seat 5, indicating component 6, exhaust structure 7, anti-clogging structure 8, fixing component 9, retaining ring 10, retaining groove 11, straight anti-clogging groove 12, cross-shaped anti-clogging groove 13, star-shaped anti-clogging groove 14, fastener 15, gap groove 16, and sealing ring 17, the possibility of using other terms is not excluded.
