Embodiment 1

[0047] Figure 5 , Figure 6 The sealing ring can be moved up, and the elastic body adopts the embodiment of gradual cylinder and conical helical compression elasticity.

[0048] The top of the sealing ring 4 is equipped with a sealing ring holder 6, and some spring supports 7 are fixed on the sealing ring holder 6. The spring support 7 can be stretched up and down, and the spring support 7 is equipped with a compression spring 8. Of course, the spring 8 can adopt other suitable spring.

[0050] Figure 8 It is a schematic diagram of the maximum deformation of the compression spring when it is above the safe steam pressure;

[0051] Figure 9 It is another kind of spring supporting type that embodiment 1 adopts, and there are many kinds of supporting members of the spring, which cannot be listed one by one.

Embodiment 2

[0055] Figure 10 and Figure 11For sealing ring can move up, elastic body adopts the embodiment of abrupt type torsion spring.

[0056] A sealing ring holder 6 is disposed above the sealing ring 4, and a plurality of torsion springs 10 and balance rings 9 are arranged on the sealing ring holder 6. The mandrel of the torsion spring 10 is fixed on the sealing ring holder 6 . The balance ring 9 is drilled with a hole corresponding to the end hole of the torsion spring 10, and a bolt is fixed in the hole, and the bolt passes through the end hole of the torsion spring 10.

[0057] Figure 12 It is a schematic diagram of the mutation type torsion spring of embodiment 2 in a normal state;

[0058] Figure 13 for Figure 12 A view from direction A.

[0059] The torsion spring 10 has a preset torque and a preset torsion angle. When the steam pressure in the pot is set as a safe pressure (for example, 100KPa), the steam pressure that each torsion spring bears is P, then the pre...

Embodiment 3

[0066] Figure 18 and Figure 19 It is an embodiment that the sealing ring can move outward (move toward the pot body), and the elastic body adopts a gradual tension spring.

[0067] The sealing ring 4 is placed on the edge of the pot body 1 and the lid 2, and a number of tension spring rings 11 are arranged on the outside (the spring ring can also be placed in the sealing ring). Before the two ends of the spring ring are connected, an appropriate amount of A short cylinder (other supports can also be used) to prop up the spring coil, so that the stretched spring coil produces a preset internal tension. The internal pressure generated by this tension is equal to the steam pressure in the pot as a safe pressure (for example, 100KPa ), the pressure of the steam on the sealing ring. Because of the supporting function of the supporting part in the spring ring, when there is no steam pressure, the spring ring has no pressure on the sealing ring, and the sealing ring and the sprin...

Abstract

The invention is a cooking utensil, a safety pressure cooker, and aims to provide a safety pressure cooker with simple and reliable structure and no explosion. The pressure cooker comprises a pot body, a pot cover, a pressure limiting valve and a sealing ring. It is characterized in that the sealing ring is connected with the elastic body, and the sealing ring moves or rotates under the action of the steam pressure in the pot, and its action is controlled by the elastic body. The elastic body is added with a preset force or a preset torque, and its value is equal to the pressure or torque of the steam on the sealing ring when the steam pressure in the pot is a safe pressure. Therefore, when the steam pressure in the pot is lower than the safety pressure, the sealing ring will not move and maintain its sealing effect. But when the steam pressure in the pot exceeds the safety pressure, the pressure or torque of the steam in the pot on the sealing ring is greater than the preset value of the elastomer, so that the sealing ring moves or rotates, and a gap is formed between the sealing ring and the pot body and cover. The steam releases and the steam pressure decreases. The safety device has the advantages of simple structure, stability and reliability, and can effectively eliminate potential safety hazards of the pressure cooker.

Description

technical field [0001] The invention is a cooking utensil, which is a safety pressure cooker. Background technique [0002] More than 300 years have passed since the invention of the pressure cooker, and the inherent safety problems of the pressure cooker have not been completely resolved. The explosion of the pressure cooker, damage to property, injury, and even death has never stopped all over the world, and it is becoming more and more serious. the trend of. [0003] According to very incomplete records reported by the media, from 2008 to 2016, there were 184 pressure cooker explosions in some areas, 13 people were killed and 95 people were injured, including serious injuries (severe burns, severe burns, severe disfigurement, severe blows to the head) , craniocerebral injury, eyeball burst, blasted blind eye, comminuted fracture, broken hand, broken finger, broken leg, ruptured Achilles tendon, ruptured spleen, large wound, exposed bone, etc.) 54 people suffered countles...
