Description

Handle overhead type safe pressure cooker

The utility model relates to the family expenses pressure cooker in a kind of daily living article, specifically is handle overhead type safe pressure cooker.

Pressure cooker is as a kind of modern cook utensil, owing to have and save time, energy-conservation, the advantage of cooking food unique flavor, become huge numbers of families' necessity for life, yet, so far, commercially available pressure cooker all adopts the tight fit sealing device, the folding pot cover needs very great strength, then adopt long handle as boosting-rod folding pot cover, in order to guarantee the safety of folding lid, generally adopt the thrust valve to add that complicated apparatus realizes above the handle, the pressure cooker of this structure is waste material not only, has increased packaging volume, and easy break-down again in use, consumers in general's strong request production structure is simple, the safe pressure cooker that fault is few.

The purpose of this utility model provides a kind of handle overhead type safe pressure cooker at above-mentioned situation exactly, has simple in structure, good reliability, low cost and other advantages.

The technical solution of the utility model is: constitute by pot body, pot cover assembly, sealing ring and handle, wherein pot cover radially by the push rod guide pin bushing push rod is housed with the sealing ring corresponding position, at the baffle plate that two notches about band are arranged on the handle.

According to technique scheme and since the utility model pot cover push rod radially is housed, the baffle plate that has notch is arranged on the handle, they have formed collection novelty, safety, a reliable in function with sealing ring is the folding cover ensuring equipment of one.When having external force, push rod do not do the time spent, be subjected to the effect of sealing ring elastic force to be exposed at the outside of pot cover, when closing lid when not in place, push rod is subjected to the extruding of handle overhead gage and moves to the inside and to withstand sealing ring, make the upperlip of sealing ring leave pot body and pot cover and destroy sealing, do not let out when most when pot inner pressure, dynamic seal ring does not go out the notch of block on the handle to push rod because of pushing up not, thereby does not open pot cover.

The utility model adds the gap of cauldron body and pot cover point of attachment, adds the distance of large sealing packing ring upperlip, and the lip with sealing ring extends simultaneously, thereby reduces the resistance of folding lid, and good airproof performance.

The utility model is equipped with knob at the pot cover top, has so just saved the long handle of afterburning rod-type, and by the knob pot cover, promptly easily folding is covered.

The utility model connects knob with blast pipe, and pressure limiting valve and knob are fitted together, and has so promptly saved the thrust valve.

Therefore, the handle overhead type safe pressure cooker that the utility model provides, modern design, simple and reasonable for structure, good reliability, cost is low, and volume is little, reduces usage space, saved packing and cost of transportation, met the GB13623-92 standard, good popularization value has been arranged.

Describe in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents structural representation of the present utility model;

Scheme the part of overlooking of Fig. 2 presentation graphs 1;

Fig. 3 represents the partial sectional view of sealing state;

Fig. 4 represents the partial sectional view of non-tight state;

Fig. 5 represents the partial sectional view of pot cover.

Referring to Fig. 1, the utility model is to comprise pot cover 5, alarm valve 6, pressure limiting valve 8, blast pipe 9, safety valve 12 by pot body 13, pot cover assembly, and sealing ring 4 and main handle 1, auxilliary handle 14 are formed.Radially by push rod guide pin bushing 3 push rod 2 is housed at pot cover 5 with sealing ring 4 corresponding positions, have on the main handle 1 have about the baffle plate 112 of two notches 111, one of them notch place indicates " closing " printed words, and another notch place indicates " opening " printed words, as shown in Figure 2.At the top of pot cover 5 knob 7 being housed, is to connect knob 7 with blast pipe 9 by pressboard padding and nut 10,11, pressure limiting valve 8 and knob 7 is fitted together, as shown in Figure 5.Simultaneously, strengthened the gap of pot body 13, added the distance of large sealing packing ring 4 upperlips with pot cover 5 points of attachment, and with the lip lengthening, shown in Fig. 3,4.

Its principle is as follows: close when covering, push rod 2 on the pot cover 5 puts down at notch 111 places that main handle 1 is marked with " opening " word, holding knob 7 up times rotates, at this moment, block 112 on the main handle 1 withstands push rod 2, make that push rod 2 is stressed to be moved inward and withstand sealing ring 4 and also move inwards, make the upperlip of sealing ring 4 leave pot body 13 and pot cover 5, do not enter when " closing " the word notch on the main handle 1 at push rod 2, pot is in the blow-by state, can not enter pressure, the security insurance state that covers is closed in formation, when push rod 2 enters the notch of " closing ", has removed the external force to push rod 2, make push rod 2 be in free state, sealing ring 4 is under the elastic force effect, upperlip is close on pot body 13 and the pot cover 5 and is formed sealing.When uncapping, most if pot inner pressure is not let out, because sealing ring 4 is subjected to air pressure and swelling pot body 13 and pot cover 5, dynamic seal ring 4 can not screw out in " closing " notch push rod 2 because of pushing up not, knob 7 volumes are little in addition, the little and lid of not opening of carry-over moment, the security insurance of uncapping that Here it is.
