Abstract
A safety device for pressure cooker comprises a pressure limiting valve, a safety valve, an open-arresting valve and a combined pushing component, wherein, an upper handle is provided with an opening hole for the open-arresting valve to move; the safety valve is arranged in the open-arresting valve, which makes the safety valve serve as the open-arresting valve; a cover has a small number of opening hole, which makes the manufacturing convenient and makes the pressure cooker have a compact structure. Because the combined pushing component is a formed piece with a head pushing part on the low part, the combined pushing component has a small number of parts and is reliable in operation; because the opening hole of the open-arresting valve is bigger, the opening hole can be made by means of the flanging art, thereby lowering the manufacturing cost.
Description
The utility model relates to the pressure cooker technical field, particularly a kind of pressure cooker safety locking motion.
The safety locking motion of existing pressure cooker generally comprises: pressure limiting valve, safety valve, stopping valve etc.A kind of " pressure cooker use safeties " are just disclosed for No. 98212422.8 as Chinese patent.Be respectively equipped with on its pot cover and pressure limiting valve, safety valve, corresponding three perforates of stopping valve,, make that manufacturing process is many, cost is high because the perforate on the pot cover is more.Moreover, its safeties are made of push rod, stage clip, combination push piece, stopping valve etc., push rod connects the combination push piece by the mode of riveted joint or welding, makes the complex structure of safeties, parts many, and each parts factor all can influence pressure cooker functional reliability and quality.
The purpose of this utility model is: provide a kind of pot cover perforate pressure cooker safety locking motion less, rational in infrastructure at above-mentioned shortcoming.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of pressure cooker safety locking motion comprises pressure limiting valve, safety valve, stopping valve, combination push piece, and upper handle is provided with and can holds the perforate that stopping valve moves; Described safety valve is located in the stopping valve, and the stopping valve bottom is provided with sealing ring.
In the utility model, described safety valve comprises spool, the valve head of being located in the valve body, is provided with spring between spool and valve head, and the spool bottom is provided with sealing ring, the whole one-tenth of safety valve one stopping valve spool; But pot cover, upper handle and combination push piece are provided with manner and open the perforate that valve core moves up and down.The combination push piece is a profiled member, and its underpart becomes the portion of cutting somebody's hair, and the portion of cutting somebody's hair pushes down a pot tooth, is provided with a spring between combination push piece and upper handle inboard.The perforate that safety valve is set on the pot cover forms through flange.Age of a draught animal portion on the described pot cover is provided with and makes up the prominent point in location that the push piece portion of cutting somebody's hair is complementary.
Advantage of the present utility model is: because safety valve is located in the stopping valve, safety valve integral body has become the spool of stopping valve, make safety valve have the function of stopping valve concurrently, and the perforate on the pot cover is few, makes easy to processly, and pressure cooker is succinctly whole.Because the combination push piece is a profiled member, its underpart becomes the portion of cutting somebody's hair, and makes that combination push piece parts are few, reliable operation.Because safety valve is set in stopping valve, the perforate of stopping valve is bigger, and perforate can be made by flanging process, reduces manufacturing cost.Because the age of a draught animal portion on the pot cover is provided with the prominent point in location, and pot cover is only rotated in control range, and is easy to use.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model combination push piece portion enlarged drawing.
Fig. 3 is the utility model pot oral area schematic diagram.
In conjunction with Fig. 1, shown in Figure 2, the pressure cooker safety locking motion comprises: pressure limiting valve 3, safety valve 4, stopping valve, combination push piece 5, and safety valve is located in the stopping valve, the whole one-tenth of safety valve stopping valve spool; The stopping valve bottom is provided with sealing ring 14.But pot cover 1, upper handle 10 and combination push piece 5 are provided with manner and open the perforate that valve core moves up and down.When reaching certain pressure in the pot, stopping valve can rise voluntarily.Safety valve 4 comprises spool 6, the valve head of being located in the valve body 7, is provided with spring 8 between spool and valve head, and the spool bottom is provided with sealing ring 9.When pot inner pressure surpassed safety value, the gas pressure that the safety valve spool is subjected to was greater than elastic force and its gravity sum of spring 8, spool rising pressure release.The combination push piece is a profiled member, and its underpart becomes the portion 11 of cutting somebody's hair, and the portion of cutting somebody's hair pushes down the pot tooth on pot body 2, is provided with a spring 12 between combination push piece and upper handle inboard.Because safety valve will be set in stopping valve, the perforate of stopping valve is bigger, makes the perforate of stopping valve on the pot cover, can make by flanging process, not only can reach specification requirement, also can reduce production process, reduces cost.
As shown in Figure 3: the age of a draught animal portion on the pot cover is provided with the prominent point 13 in a location.The work that matches with the portion of cutting somebody's hair that makes up push piece of the prominent point 13 in location makes pot cover only rotate in control range, and is easy to use.
When using pressure cooker safety locking motion of the present utility model, in case pressure cooker lid is not incorporated into the position, the protruding tooth of pot oral area just withstands the portion of cutting somebody's hair of combination push piece, makes the combination push piece cover stopping valve (safety valve), stopping valve can not rise, and the pot internal gas pressure is discharged by the gap of stopping valve.When pot cover is incorporated into the position, the combination push piece cut somebody's hair clan in the recessed tooth of pot oral area, the combination push piece is under the effect of spring, its position of opening is over against stopping valve (safety valve); When reaching certain pressure in the pot, stopping valve rises and seals voluntarily, and positive pressure is often worked on the pressure cooker, covers safe requirement to reach to close.When pressure cooker stops heating, a pot internal gas pressure is not also reduced to safety when uncapping pressure, and stopping valve (safety valve) blocks the combination push piece, and pressure cooker can not be opened.When pot internal gas pressure to safety was uncapped pressure, stopping valve (safety valve) fell voluntarily, and pressure cooker just can be opened, and is safe in utilization.
When the pressure cooker internal gas pressure surpassed safety value, the spool in the safety valve rose under gas pressure, makes pot inner pressure drop to safe range.
