Abstract
The utility model discloses a safety device for closing and opening cover of a rotary pressure cooker. The performance characteristics of the device are as follows: when the cover of the cooker is not in place or is out of position, the pressure in the cooker rises to be not more than 3 KPa; when the pressure in the cooker exceeds 3KPa, the cover can not be opened. The device consists of a valve, a lever, a sliding block, a spring, an upper handle, a lower handle and a plurality of standard components. It is convenient to operate and can greatly improve the safety performance of the original rotary-closing pressure cooker.
Description
The utility model relates to a kind of kitchen utensils, particularly a kind of pressure cooker of revolving type structure.
The pressure cooker of Xiao Shouing in the market, the overwhelming majority is the pressure cooker of revolving type structure.It is made up of parts such as pot body, pot cover, sealing ring, pressure limiting valve, flame-arrester vent plug, upper handle, lower handles.It has the characteristics of time-saving energy-saving, and multiple cooking function is arranged again.In recent years, increasing people liked the working pressure pot, and still, the pressure cooker of present this revolving type also exists some problems on safe application performance.The user who has is owing to lack knowledge or general idea, and it is not in place or offside to close lid during use, and too small when superimposed area, pressure cooker can be caused danger in the process of boosting.Also have a kind of situation to be: after boiling slop, mention the pressure limiting valve weight, the gas band the material that stops up blast pipe easily, as skin of beancurd, fiber food etc., after exhaust a period of time, steam vent is blocked, and still have pressure in a small amount in the pot, and do not have the people of experience not discover, firmly uncap, will meet accident, more than two kinds of explosion accidents that situation is easy to make pressure cooker.
The purpose of this utility model provides and a kind ofly meets that the revolving type pressure cooker closes lid, the safe handling requirement of uncapping; When closing lid when not in place or offside, the pot inner pressure super only 3Kpa that raises; When the pressure that has in the pot above 3Kpa, the safety device that lid is not opened.
Content of the present utility model is when addressing the above problem, be to design like this: in the place of pot cover near upper handle, increase a pressing face, punching in the plane is provided with a plunger with the aluminium rivet transformation of the way in the hole, bore an aperture on the plunger small end, sealing ring on the plunger bushing, fill in and cover in the hole, load onto pin on aperture, this has just constituted a valve.The redesign upper handle, upper handle is equipped with lever, spring, slide block, lever supporting screw, slide block connects screw, spring washer, packing ring.Pass upper handle with long screw, the slotted eye of lever is fixed on the pot cover.The lower handle of redesign is provided with two positive stop lug boss, a cam.
Below further describe principle of the present utility model by accompanying drawing.
Accompanying drawing 1 is the assembling schematic diagram of package unit.
Accompanying drawing 2 is that vertical view disconnects upper handle part position, the key position schematic diagram of the lower handle that draws.
Close and cover the security performance principle: closing before the lid does not have pressure in the pot, and plunger 1 falls, and pin 3 is hung plunger, and lever 4 is by the screw supporting, and the end that tilts is pushed down plunger 1, and the other end is reduced in the upper handle 5.When closing lid when not in place or offside, upper handle 5 does not overlap with lower handle 13, and slide block 9 is lived in the rectangular apertures that handle 5 is provided with in the pressure lower seal of spring 10, and lever 4 just can not be fallen in two boss of lower handle 13 settings.Because slide block 9 or lower handle 13 do not overlap, slide block 9 has the pressure lower seal to live in the rectangular apertures that handle 5 is provided with at spring 10, lever 4 just can not be fallen in two boss of lower handle 13 settings, because the boss of slide block 9 or lower handle 13 is held lever 4, and lever 4 is pushed down plunger 1, the fit clearance of pot cover hole and plunger 1 constitutes passage, and steam is discharged, and pressure just can not rise.When closing lid when putting in place, last lower handle overlaps, and the cam of lower handle 13 is pushed down the hook of setting on the slide block 9, and slide block is moved apart lever 4.When pot inner pressure is raised to making a concerted effort of the pressure that tilts greater than plunger 1 gravity and lever 4, plunger 1 rises to the top, sealing ring 2 sealed pot cover holes on the plunger 1, an and end of jack-up lever 4, the other end of lever 4 passes in two boss that upper handle 5 is inserted into lower handle 13, and pot inner pressure continues to rise to the operating pressure that pressure limiting valve uses.
The security performance of uncapping principle: before uncapping, even blast pipe stops up, also there is very little pressure in the pot, even has only the pressure of 3Kpa, plunger 1 a stressed end that upwards heads on lever 4, the other end of lever 4 passes the rectangular apertures of upper handle 5, is inserted between two boss of lower handle 13, has played the effect of pinning pot cover.Reached and had the security performance that a small amount of pressure also can not be uncapped in the pot.Plunger 1 upwards floats also visiblely in addition, illustrates in the pot to also have a pressure, plays the effect of reminding the user to note, when pot inner pressure is rejected to less than the making a concerted effort of the gravity of plunger 1 and lever 4 inclined gravity, and plunger 1 downward landing.The end that lever 4 tilts to be inserted between 13 liang of boss of lower handle rises, and leaves lower handle 13, the safety of at this moment uncapping.After uncapping, the hook of slide block 9 has left lower handle, resets at the active force sliding block 9 of spring 10, holds lever 4.Such covering device repeatedly in the use, has played very reliable safeguard protection effect at the revolving type pressure cooker.
Compare with the revolving type pressure cooker of selling on the present market, increase and close lid, the safety device of uncapping, cost increases few, but it can increase by two security performances, and very worth beyond doubt to the user.
The utility model except considering safe reliability, is also considered user's custom emphatically, and is easy to operate, and the design of package unit is through design repeatedly, and modification is just finished repeatedly.We can say that the utility model design will improve major step to the security performance of original revolving type pressure cooker.
