DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The present invention provides a technical solution: a stop-opening explosion-proof pressure cooker, comprising: a pot body 1 and a pot cover 2, wherein the pot body 1 and the pot cover 2 are rotatably engaged with each other so that the pot cover 2 and the pot body 1 are fastened.

[0025] A handle 7 is symmetrically installed on the side of the pot body 1, and a limit card 6 is integrally provided on the handle 7. A fixed beam 3 is arranged on the pot cover 2, and slots 31 are symmetrically opened at both ends of the fixed beam 3. The slots 31 are plugged with the limit cards 6 in the upper and lower directions. When the fixed beam 3 and the pot cover 2 are fixed, the pot cover 2 cannot be rotated and opened relative to the pot body 1 due to the cooperation between the slots 31 and the limit cards 6. When the fixed beam 3 and the pot cover 2 can rotate relatively, the pot cover 2 can be rotated and opened relative to the pot body 1.

[0026] A limit hole 32 is provided on the fixed beam 3, and a stop-opening safety valve 4 is provided on the pot cover 2. The stop-opening safety valve 4 is raised by the internal pressure of the pot body 1 and plugged into the limit hole 32. By utilizing the principle of the latch, the pot cover 2 and the fixed beam 3 cannot rotate relative to each other. When the internal pressure of the pot body 1 is relieved, the stop-opening safety valve 4 falls back, and the pot cover 2 and the fixed beam 3 can rotate relative to each other.

[0027] The non-opening safety valve 4 comprises a fixing seat 41, on which a tightening nut 43 is threadedly connected, and the tightening nut 43 cooperates with the fixing seat 41 to be clamped on the pot cover 2, and a sealing ring 42 is sleeved on the contact surface with the pot cover 2 to achieve sealing;

[0028] A lifting column 44 is slidably disposed in the fixing seat 41, a clamp 46 is threadedly mounted on the upper end of the lifting column 44, a bottom hole 411 is provided at the lower end of the lifting column 44, a sliding plug 47 is slidably disposed inside the lifting column 44, and a spring 45 is disposed between the sliding plug 47 and the clamp 46;

[0029] When the pressure inside the pot body 1 rises, the pressure presses the sliding plug 47 through the bottom hole 411, overcomes the force of the spring 45, lifts the clamp 46, and drives the entire lifting column 44 to rise, and the clamp 46 is inserted into the limiting hole 32 to achieve relative fixation. When the pressure inside the pot body 1 is relieved, the spring 45 is reset, the lifting column 44 falls back, and the clamp 46 is separated from the limiting hole 32.

[0030] A knob cover 5 is installed in the middle of the fixed beam 3. The knob cover 5 is fixedly connected to the pot cover 2 through a fixed connection piece 51. The fixed connection piece 51 penetrates the fixed beam 3. The upper end surface of the pot cover 2 is located on both sides symmetrical to the fixed connection piece 51 and fixedly installed with fixing posts 53. The fixing posts 53 are plugged into the sockets 54 opened at the lower end of the knob cover 5, so that the knob cover 5 is radially fixed to the pot cover 2.

[0031] The fixed beam 3 is symmetrically provided with arc grooves 33, and the fixed column 53 movably penetrates the arc grooves 33, so that the fixed beam 3 and the pot cover 2 can be relatively rotated at a certain angle to realize opening of the cover.

[0032] Spring clips 52 are symmetrically arranged on both sides of the fixed connecting member 51. The lower end of the spring clips 52 is fixedly installed on the through hole 34 of the fixed beam 3. The upper end of the spring clips 52 is provided with a spring-supported steel ball. The spring clips 52 are slidably connected to the card point groove 55 opened on the lower end surface of the knob cover 5. Concave points are arranged at both ends of the card point groove 55, and the concave points are engaged with the steel balls. When the knob cover 5 is rotated a certain angle relative to the fixed beam 3, the steel balls are instantly stuck in the concave points, which has a certain hand feel, prompting the user to rotate the knob cover 5 into place relative to the fixed beam 3.

[0033] Working principle: the fixing beam 3 is connected with the limit card 6 to fix the fixing beam 3 radially relative to the pot body 1. When the fixing beam 3 and the pot cover 2 are also radially fixed, the pot cover 2 and the pot body 1 cannot be rotated to open. When the fixing beam 3 and the pot cover 2 are not radially fixed, the pot cover 2 and the pot body 1 can be opened smoothly. The connection relationship between the fixing beam 3 and the pot cover 2 is controlled by the non-opening safety valve 4. When the pressure inside the pot body 1 increases, the non-opening safety valve 4 rises, and the fixing beam 3 and the pot cover 2 are fixed by the principle of the latch. When the pressure is relieved, the non-opening safety valve 4 falls back, and the fixing beam 3 and the pot cover 2 are no longer radially fixed, thereby improving the safety of the pressure cooker.
