Technical Field

The present invention relates to a pressure cooker.

Background

The pressure cooker can raise the physical phenomenon that the boiling point of liquid under higher air pressure exerts pressure on water, so that the water can reach higher temperature without boiling, thereby accelerating the efficiency of stewing food. The utility model can heat the cooked food to more than 100 ℃, and in high altitude areas, the pressure cooker can avoid the problem that the food is not easy to cook because the boiling point of water is reduced.

But if the pressure cooker uses very big potential safety hazard when not standardizing, if the misuse or children are not intelligible opens, will cause injury or even death to the health, domestic a large amount of lid pop out when opening the pressure cooker lid, give people and cause the injury, this is because the pressure in the pot has not released and has not opened the lid yet, the impact force of huge like this will cause the injury to the human body, also some float through observing the pot body falls and just judges whether to open, if appear the float block or when damaging, open and have danger equally.

Therefore, the existing pressure cooker is further improved.

Disclosure of Invention

The invention aims to provide a structure which is provided with a safety protection device and can open a pot cover only after air pressure is reduced.

In order to achieve the purpose, the invention adopts the following scheme:

the utility model provides a pressure cooker that possesses safety protection structure, is including pressure cooker body and upper cover be provided with a plurality of bayonets on the pressure cooker body cover on be provided with be used for with a plurality of bayonet socket matched with a plurality of buckles, be provided with in the bayonet socket with the inside elasticity locking post that communicates of pressure cooker body, be provided with on the buckle after the closed pressure cooker body opening of upper cover and the locking hole of aligning from top to bottom of elasticity locking post.

Further, elasticity locking post is including setting up in bayonet socket below and with the cavity of the inside intercommunication of pressure cooker body, be provided with vertical setting in the cavity and with the through-hole of bayonet socket intercommunication, the upper and lower edge of through-hole respectively is provided with the spacing ring, the through-hole internalization is provided with the safety post, safety post circumference outer wall is provided with the ring of going of ending, be provided with elastic mechanism between the spacing ring of the ring of going of ending and top.

Furthermore, the elastic mechanism is a spring, the spring is sleeved outside the safety post, and two ends of the spring are tightly pressed on the surfaces of the upper limiting ring and the upper stopping ring.

Further, a sealing structure is arranged between the limiting ring and the safety post.

Further, the sealing structure is a sealing ring, and the sealing ring is fixedly arranged on the inner wall of the limiting ring below.

Further, the locking hole is an arc-shaped notch.

Furthermore, the edge of the upper end of the safety post is provided with a guide round angle.

Furthermore, the pressure cooker body and the upper cover are respectively provided with a first handle and a second handle.

In summary, compared with the prior art, the invention has the beneficial effects that:

the invention solves the defects of the existing pressure cooker, ensures the structure that the cooker cover can be opened only after the pressure in the cooker is completely released, has a multilayer protection device, ensures the property safety of people, adopts a physical locking structure to be more stable and safer, and has simple structure and convenient use.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution:

a pressure cooker with a safety protection structure comprises a pressure cooker body 1 and an upper cover 2, wherein a plurality of bayonets 3 are arranged on the pressure cooker body 1, a plurality of buckles 4 matched with the bayonets 3 are arranged on the upper cover 2, elastic locking columns 5 communicated with the interior of the pressure cooker body 1 are arranged in the bayonets 3, and locking holes 6 aligned with the elastic locking columns 5 up and down are formed in the buckles 4 after the upper cover 2 closes an opening of the pressure cooker body 1;

The structure principle is as follows:

when pressure exists in the pressure cooker body 1, the internal pressure can make the elastic locking column 5 upwards bounce, and simultaneously, the card is gone into and is carried out vertical card in the locking hole 6 and establish, at this moment, if want to open the pot cover, then can't open, because the elastic locking column 5 has blocked the locking hole 6 on the buckle 4, makes the upper cover 2 unable rotation.

When the internal pressure is completely released, the elastic locking column 5 resets to enable the elastic locking column 5 to contract, and at the moment, the pot body is proved to have no pressure, and the upper cover 2 can be normally rotated and opened.

The invention relates to an elastic locking column 5, which comprises a cavity 501 arranged below a bayonet 3 and communicated with the interior of a pressure cooker body 1, wherein a through hole 502 which is vertically arranged and communicated with the bayonet 3 is arranged in the cavity 501, limiting rings 505 are respectively arranged at the upper edge and the lower edge of the through hole 502, a safety column 503 is movably arranged in the through hole 502, a stopping ring 504 is arranged on the circumferential outer wall of the safety column 503, an elastic mechanism 100 is arranged between the stopping ring 504 and the upper limiting ring 505, when pressure exists in the pressure cooker body 1, the pressure can pass through the cavity 501 and press the safety column 503 to rise, so that the stopping ring 504 rises to the height of the surface of the limiting ring 505, the safety column 503 is clamped in a locking hole 6, at the moment, a closed upper cover 2 is locked and cannot be opened, after the pressure is released, the elastic mechanism 100 enables the safety column 503 to reset, and the safety column 503 leaves the locking hole 6, the upper cover 2 can be safely opened.

The elastic mechanism 100 is a spring, and the spring is sleeved outside the safety post 503, and two ends of the spring are tightly pressed on the surfaces of the upper limit ring 505 and the stop ring 504.
