Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, specifically a low-pressure cooker. Background Technology

[0002] Pressure cookers are cooking utensils primarily made of metal, and their design focuses on innovative shapes. These products often utilize multi-layered stainless steel with a three-layer composite structure: an inner layer of food-grade stainless steel, a middle layer of pure aluminum heat-conducting material, and an outer layer of magnetically conductive stainless steel, combining safety and energy efficiency.

[0003] The following technical defects are commonly found in low-pressure cookers currently on the market:

[0004] Insufficient exhaust safety: Traditional designs rely on a single low-pressure valve, which is prone to blockage leading to pressure buildup and the risk of explosion.

[0005] Poor user experience: The handle design is often not ergonomic, causing fatigue during prolonged use, and the locking mechanism is cumbersome to operate.

[0006] Therefore, we proposed a low-pressure cooker to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example

[0033] like Figure 1-6 As shown, an embodiment of the present invention provides a low-pressure cooker, including a pot body 1 and a sealed glass cover 2. The sealed glass cover 2 is provided with a low-pressure valve 22 and an explosion-proof silicone plug 23. Bakelite locking blocks 4 are movably provided on both sides of the pot body 1.

[0034] like Figure 4-6 As shown, in some embodiments, the top of the sealing glass cover 2 is provided with a bakelite handle 21, and the top of the low-pressure valve 22 extends through to the top of the bakelite handle 21.

[0035] The bottom of the bakelite handle 21 is elongated, serving as a handle base for greater stability. The top handle is curved, conforming to ergonomics and making it easier for users to grip. The top of the handle base has an arc-shaped recess to avoid the low-pressure valve 22. This design prevents food residue ejected from the low-pressure valve 22 from entering the handle.

[0036] like Figure 4-6 As shown, in some embodiments, the low-pressure valve 22 is provided with an aluminum screw 24, and the explosion-proof silicone plug 23 is located on one side of the bakelite handle 21.

[0037] The main function of the low-pressure valve 22 is to regulate and control the pressure inside the pot, keeping it at a low pressure to shorten cooking time and improve the taste of food. It prevents excessive pressure by automatically venting, ensuring efficient and stable cooking. If the low-pressure valve 22 becomes blocked due to abnormal pressure rise, the explosion-proof silicone plug 23, with its flexible structure, will be pushed open by the air pressure to release pressure, avoiding the risk of explosion. The two work together to optimize cooking efficiency and ensure safety.

[0038] like Figure 4-6As shown, in some embodiments, a sealing ring 25 is provided around the sealing glass cover 2.

[0039] The sealing ring 25 uses a combination of silicone rubber and embedded stainless steel strips for support, which greatly improves the sealing effect and can still return to its original shape after long-term pressure.

[0040] like Figure 4-6 As shown, in some embodiments, pot ears 11 are provided on both sides of the pot body 1. A bakelite pad 3 is fixedly provided at the bottom of the pot ear 11. A bakelite locking block 4 is movably provided at the top of the pot ear 11. The pot ear 11 is provided with a movable hole 13 and a limiting groove 14 located on one side of the movable hole 13. A movable block 41 with one end penetrating through the movable hole 13 is provided at the bottom of the bakelite locking block 4. A locking piece 5 is provided at the bottom of the movable block 41. A sliding groove 31 that movably engages with the locking piece 5 is provided at the top of the bakelite pad 3. A limiting strip 42 is also provided at the bottom of the bakelite locking block 4. The bottom of the limiting strip 42 is embedded in the limiting groove 14.

[0041] The slide groove 31 is used to avoid the locking piece 5 and will not affect the movement of the locking piece 5 driven by the movable block 41 through the bakelite locking block 41. The bakelite pad 3 is fixed to the pot ear 11 by screws, and the locking piece 5 is fixed to the movable block 41 by screws. After fixing, the locking piece 5 and the bakelite locking block 4 clamp the pot ear 11 relative to each other. The clamping force is adjustable by the screw tightening degree and does not affect the sliding of the bakelite locking block 4. The cooperation between the limiting strip 42 and the limiting groove 14 further ensures the sliding stability of the bakelite locking block 4. The limiting groove 14 and the movable hole 13 are both long strips to accommodate the small range of movement of the limiting strip 42 and the movable block 41.

[0042] like Figure 2 As shown, in some embodiments, the bottom of the pot body 1 is provided with a group of protrusions 12.

[0043] The protrusion group 12 makes the pot body 1 heat up faster and more evenly.

[0044] When in use, place the sealing glass cover 2 on the pot body 1, push the bakelite locking block 4 so that one end of it presses against the top of the outer edge of the sealing glass cover 2, ensuring the sealing of the sealing glass cover 2 and the pot body 1. After cooking, move the bakelite locking block 4 to reset. When the internal pressure of the pot body 1 drops to a safe range, the sealing glass cover 2 can be lifted by the bakelite handle 21.

[0045] In summary, the low-pressure valve 22 enables automatic high-pressure venting, ensuring efficient and stable cooking. The explosion-proof silicone plug 23 can be opened by air pressure when the low-pressure valve 22 is blocked, thus avoiding the risk of explosion. The two work together to optimize cooking efficiency and ensure safety. The bakelite handle 21 is curved, conforms to ergonomics, and is easy for users to hold. The bakelite locking block 4 has a push-pull operation mode, making it more convenient to use. The protrusion group 12 makes the pot body 1 heat up faster and more evenly, meeting the user's needs.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
