Upper handle of pressure cooker and pressure cooker cover opening and closing mechanism thereof

Abstract

The invention discloses an upper handle of a pressure cooker. The upper handle comprises an upper handle body (A), a button (3), a safety board (5), a rotatable locking angle (8) and an opening stop valve (E),wherein the button (3) is positioned in a button hole (2) at a side end of the upper handle body (A); a slot (4) is reserved on the button (3); a locking pin (6) positioned in the slot (4) is arranged on one side of the safety board (5); the opening stop valve (E) is positioned at the front end of the safety board (5); the button (3) is fixed to the upper handle body (A) through a positioning shaft (7); the rotatable locking angle (8) is reserved on the other side of the safety board (5); and the safety board (5) and the rotatable locking angle (8) are positioned in a sliding groove (9) on the upper handle body (A). The upper handle of the pressure cooker overcomes the disadvantages that a conventional mechanism is easy to cause an error operation and has a potential safety hazard. The upper handle of the pressure cooker has a simple structure, convenience of operation, high safety performance, simultaneously reduces machining precision, and is convenient to produce. The invention also discloses a pressure cooker cover opening and closing mechanism which comprises the upper handle.

Description

technical field [0001] The invention relates to an upper handle of a pressure cooker, and also relates to a pressure cooker lid opening and closing mechanism comprising the upper handle of the pressure cooker. Background technique [0002] According to the needs of the actual use of the pressure cooker, the pressure cooker is usually provided with an opening and closing cover mechanism including an upper handle, a lower handle and parts thereof, to control the opening and closing of the pressure cooker. And the opening and closing mechanism usually includes a safety device. The function of the safety device is: when the fastening between the lid and the body of the pressure cooker does not meet the requirements, the pressure in the pot cannot rise; when there is pressure in the pot, the lid cannot be opened. [0003] Existing pressure cooker opening and closing mechanism has many kinds, and concrete operation is also different to some extent during use. Many structures hav...

Problems solved by technology

[0004] However, in this solution, when the lid and the body of the pot are not properly fastened, that is, when misoperation occurs, the pressure cooker will be boosted during heating, so there are potential safety hazards

In addition, the above scheme still has the problem that the structure is relatively complicated and it is not particularly convenient to use

In addition, the existing rotatable clip angle is assembled under the safety plate. This installation method makes it easy to generate cumulative errors between the rotatable clip angle and the sliding feet, and it is easy to cause the problem of early return of the safety plate, which is inconvenient to use and easy to damage.
