Abstract
The utility model relates to an automatic safety device for the opening and closing cover of a pressure cooker. The utility model is composed of a steam outlet hole, a sealing rubber sleeve, a support sleeve, a spring rubber pad, a support seat, a safety pin, a sealing rubber pad and screws. The steam outlet hole is arranged on a cooker cover. The support seat, the support sleeve, a sealing rubber pad, etc. are arranged on a cooker body. When the cooker cover is covered on the pressure cooker, the safety pin is just corresponding to the steam outlet hole. When the safety pin (8) is propped up by the air pressure, the sealing rubber cushion (9) tightly presses the root of the support sleeve (4). The utility model has the advantages of facility, simple structure, firmness, practicality, safe operation, and long service life.
Description
The utility model belongs to a kind of pressure cooker open and close cover automatic safety.
At present, it is of all kinds to press the pot lock uint of being engaged in to have, as patent 95244228.0 pressure cooker open and close safety controls, patent 95230981.5 pressure cooker safety devices, structure are complicated, and technology is complicated, easy cleaning not, damage easily, practicality is strong inadequately, can not effectively solve when uncapping still surplus more atmospheric phenomenon in the pot, difficulty is installed, use safety inadequately, convenient, firm inadequately inadequately.
The purpose of this utility model is to provide a kind of easy installation, and is safe in utilization, simple in structure, firm pressure cooker open and close cover automatic safety.
The utility model is by exhaust hole, seal rubber sleeve, splicing sleeve, spring rubber cushion, supporting base, safety plug, seal gasket, screw is formed, exhaust hole (2) is opened on pot cover (1), supporting base (7) is contained on pot body (11), splicing sleeve (4) is placed in the supporting base (7), safety plug (8) is placed in the splicing sleeve (4), seal gasket (9) and sealed screw (10) are contained in safety plug (8) lower end, seal rubber sleeve (3) is enclosed within splicing sleeve (4) upper end, when pressure cooker gets togather when covering, safety plug (8) aligns the exhaust hole position; Air pressure is with on safety plug (8) top time, and seal gasket (9) compresses splicing sleeve (4) root.
The utility model is simple in structure, and is very firm, and women and children all can operate, and are effective, and long service life can prevent reliably that misoperation from promptly closing in the not in place and pot of lid band strong phenomenon of uncapping during air pressure, is worth promoting.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view;
Fig. 3 closes lid schematic diagram not in place for the utility model;
Fig. 4 is the structural representation of another embodiment of the utility model.
As shown in Figure 1 and Figure 2, this device is made up of pot cover (1), exhaust hole (2), seal rubber sleeve (3), splicing sleeve (4), spring rubber cushion (5), rivet (6), supporting base (7), safety plug (8), seal gasket (9), sealed screw (10), pot body (11).Earlier at two installing holes of pot body (11) upper punch, use rivet (6) that bearing (7) is riveted tightly in the pot body again, best fit density can solve by adjustment splicing sleeve (4), spring rubber cushion (5), spring rubber cushion (5) is packed on the splicing sleeve (4), to support block set again goes in the support column (7) (4), to be tightened on the safety plug with the sealed screw of seal gasket (9), seal rubber sleeve (3) is locked on the top of splicing sleeve.At last, the marginal position at pot cover dashes an exhaust hole, the downward boss location that dashes on pot body tooth.Its operation principle is: safety plug (8) blind hole is steam discharge not, and is very sensitive up and down, when Dang Hegai puts in place, by the tension of spring rubber cushion (5), the splicing sleeve of being with seal rubber sleeve (3) tightly suppressed the edge of exhaust hole, reaches sealing function.In pot, produce when seldom measuring gas, safety plug (8) can be gone up the centre that enters exhaust hole (2) at once, seal gasket (9) is along with the root of being close to splicing sleeve (4), do not have gas to spill outside the pot, when having pressure in the pot, lid is not opened, when having arranged gas, during no pressure, safety plug falls down automatically, can uncap safely in the pot.When closing lid when not in place, as shown in Figure 3, seal rubber sleeve (3) departs from original position, and lid is exhaust hole incessantly, and gas is not to discharge by safety plug, but is discharged by the marginal gap of exhaust hole, can not produce pressure in the pot, reaches to close and covers purpose of safety.As shown in Figure 4, can add a steam discharge borehole jack (12), be contained on pot cover (1) face or pot cover (1) lining in the position of exhaust hole.Seal rubber sleeve (3) is enclosed within on the steam discharge borehole jack (12), and removes the top seal rubber sleeve of cover splicing sleeve (4).Seal gasket (9) can be bowl-shape, central column, square shape.Spring rubber cushion (5) can be the plastics spring rubber cushion, metallic elastic pad, metal spring.Can not want this part yet.In addition, on the cylindrical of the inner hole wall of supporting base (7) and safety plug (8), can have gastight small-sized, straight trough, annular groove and skewed slot.
