Problems solved by technology

However, the sealing structure of their pot lids and sealing rings is to rely on the inner cover or the hanging ring ring to realize the sealing connection with the pot body, and the inner cover or the hanging ring ring is also used to make up for the insufficient elastic displacement of the pot cover. Therefore, in the above patent, there must be necessary technical features such as inner cover, hanging ring, pressure relief diameter 2, etc., so that the patented product has disadvantages such as high consumables and inconvenient cleaning during use.
In addition, the positional relationship between the sealing ring and the pot cover, the sealing relationship, and the elastic displacement parameters of the pot cover, etc., still have many defects that are not convenient for the integrated design of the product.
[0003] Apart from this, there is no relevant information

Embodiment 1

[0030] Embodiment 1. In this example, the inner diameter of the mouth of the pot body 3 is 21 cm and the maximum working pressure in the pot is 100 kPa as an example. The pot cover 1 is made of a stainless steel plate with good elasticity and a thickness of about 0.8mm, and its maximum outer diameter is selected at about 26.5cm——to form a large-diameter pot cover 1, the radius of its edge corrugation 8 is selected at about R16mm, and the concave corrugation The radius of 9 is selected around R12mm, the corrugation depth of concave corrugation 9 is selected around 12mm, and the transition between edge corrugation 8 and concave corrugation 9 is smooth. Its geometric dimension of the hard center of pot cover 1 is related to the design requirements of the whole and appearance. In the present embodiment, the pot lid button 10 is arranged on a plane with a diameter of about 10 cm in the hard center of the pot lid 1, and the plane is higher than the top of the edge corrugation 8 by a...

Embodiment 2

[0032] Embodiment 2, this example is example with pot body 3 inner diameters 19cm, and pot cover 1 selects good elasticity, and thickness is the stainless steel plate making of about 0.7mm for use, and its maximum external diameter is selected at about 24cm, or the large pot cover 1 shape. The difference from Example 1 is that the pot lid teeth 4 of the pot lid 1 need to be turned over by using the curling process in the existing patented technology, and the number of the pot lid teeth 4 is selected as 5, so as to increase the closure of the lid Select the angle of pressure. At the same time, the pot body teeth 5 of the pot body 3 should also be consistent with parameters such as the chord length and the lift angle of the pot lid teeth 4. The remaining parameters of embodiment 2 can refer to embodiment 1.

Embodiment 3

[0033] Embodiment 3. This embodiment is based on Embodiment 1 and Embodiment 2. The pot body 3 is made of an aluminum plate with a thickness of about 2.5 mm to form a product type of a stainless steel pot cover 1 and an aluminum pot body 3 . Wherein, the thickness of the aluminum plate for making the pot body 3 matched with embodiment 1 is slightly thicker, while the thickness of the aluminum plate for making the pot body 3 matched with embodiment 2 is slightly thinner, and the pot body 3 can also adopt thinning stretching, pot body expansion, etc. Craftsmanship, strive to match with pot cover 1. For the remaining parameters of this embodiment, reference may be made to Embodiment 1 and Embodiment 2.

Abstract

A high-safety pressure cooker features that under the drive of internal pressure, its elastic cover is turned by a certain angle to generate the pressure releasing seam between sealing ring and the steam releasing slot on the edge of cooker body, resulting in high safety.

Description

Technical field: [0001] The invention belongs to kitchen pressure cooking utensils, and is a patented technology of a safe pressure cooker product. Background technique: [0002] Kitchen pressure cookers are popular in the market because of their cooking features, but the existing screw-on pressure cooker products on the market have potential safety hazards in structural design, which makes it difficult to avoid the phenomenon of product explosion. Therefore, put an end to existing potential safety hazard from the design of pressure cooker product and become the focus of technical research. Chinese invention patents ZL98101012.1 and ZL01110532.1 provide two technical solutions for safe pressure cookers. They all use the elastic displacement of the lid under the action of the inner pressure of the pot to drive the sealing ring to move up to the bottom line of the pressure relief groove, so that There is a gap in the sealing part, and the excess pressure is released to realiz...
