Abstract
The utility model relates to a switching pressure cooker pressure limiting exhaust valve, including a leverage mechanism and a pressure limiting exhaust valve body which contains a bonnet and a valve seat. The bonnet under ordinary state seals up the exhaust holes on the valve seat. The driven end of the leverage mechanism is arranged at a place available to move the bonnet from the ordinary position. The model is charaterized in that the valve aslo includes a self maintaining switch provided with a switch controlling element, which will make the driving end of the leverage mechanism move and move the bonnet from the ordinary position only when the self maintaining switch are open. The utility model has the good effects of simple structure and operation convenience. Due to the driving lever of the self maintaining switch, the lever will not reset and the pressure limiting exhaust valve maintains the degassing state even if the hand leave the switch. Moreover, the self maintaining switch is relatively far from the pressure limiting exhaust valve, thereby avoiding the operator from being scalded by the steam.
Description
Affiliated technical field
The utility model relates to a kind of pressure cooker pressure limiting air bleeding valve, especially a kind of switching regulator pressure cooker pressure limiting air bleeding valve.
Background technology
The pressure limiting air bleeding valve is a very important components of one of pressure cooker, and when normally cooking, pressure limiting valve is in " non-exhaust condition ".When inner tube of pressure cooker reached pressure at expulsion, the pressure limiting air bleeding valve discharged gas, guaranteed that pressure cooker does not exceed the safe pressure of permission; On the other hand, in the pressure cooker pot, pressure is arranged, and need open pot cover the time, will the pressed gas in the pot be discharged by the pressure limiting air bleeding valve and just can uncap.At present, when pressure cooker pressure limiting air bleeding valve needs exhaust, all be the bonnet of pressure limiting air bleeding valve to be mentioned or pull bonnet to make it to be in exhaust condition generally.Because operator's hand will contact the pressure limiting air bleeding valve, operating process is scalded by steam easily.Also have plenty of by leverage, make the bonnet jack-up of an end of lever with the pressure limiting air bleeding valve by button, when hand leaves button, lever resets immediately, and the pressure limiting air bleeding valve stops exhaust; Very inconvenient when therefore using.
Summary of the invention
In order to overcome the deficiency of existing pressure cooker pressure limiting air bleeding valve, the utility model provides a kind of not only safety but also easy to operate switching regulator pressure cooker pressure limiting air bleeding valve.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of switching regulator pressure cooker pressure limiting air bleeding valve comprises leverage and pressure limiting air bleeding valve main body, and pressure limiting air bleeding valve main body comprises bonnet and valve seat, the steam vent under the bonnet normality on the closed valve seat; The driven end of leverage is arranged on the suitable place that bonnet can be moved apart its normality position; It is characterized in that: also comprise the self-holding switch that is provided with switch control executive item, only when described self-holding switch was in out state, the drive end of its switch control executive item activation lever mechanism moved and bonnet is moved apart the normality position.
Self-holding switch be dial type control oneself switch, stick up formula switch or the button switch of controlling oneself of controlling oneself.
Pressure limiting air bleeding valve main body is Weight type pressure limiting air bleeding valve or spring pressure limiting air bleeding valve.
The beneficial effects of the utility model are, and are simple in structure, owing to adopted self-holding switch drive lever, even hand leaves switch, lever does not also reset, and the pressure limiting air bleeding valve keeps exhaust condition, and is easy to operate; And self-holding switch to leave the pressure limiting air bleeding valve far away, the danger that the operator can avoid steam to scald.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Consult Fig. 1, a kind of switching regulator pressure cooker pressure limiting air bleeding valve comprises self-holding switch, leverage and pressure limiting air bleeding valve main body; The switch of wherein controlling oneself be dial type control oneself switch, stick up formula switch or the button switch of controlling oneself of controlling oneself.Present embodiment is the example explanation with the self-holding switch of dial type.The self-holding switch of dial type is made up of with the switch control executive item 2 of stirring handle 21 switch base 1 and band push rod 20; Switch control executive item 2 left and right sides are provided with in pin (not drawing among the figure) and the corresponding gathering sill 10 of inserting switch base 1.Like this switch control executive item 2 on the switch base 1 can about fiddle with, wherein stir the outside of handle 21 at switch base 1, push rod 20 is in the inboard of switch base 1.
Described leverage is made up of lever 3 and lever seat 4 that dead axle rotates; Described pressure limiting air bleeding valve main body is Weight type pressure limiting air bleeding valve or spring pressure limiting air bleeding valve; Present embodiment is the example explanation with Weight type pressure limiting air bleeding valve.Weight type pressure limiting air bleeding valve comprises valve body 5 and bonnet 6, and valve body 5 is installed on the pot cover, and bonnet 6 places on the valve body 5.When promptly being in non-exhaust condition under the pressure limiting air bleeding valve normality, bonnet 6 utilizes deadweight to make the steam vent of its conical needle 60 sealed valve bodies 5.The drive end 30 of described lever 3 puts in switch base 1, and driven end 31 places below the bonnet 6 of pressure limiting air bleeding valve.
During use, will stir handle 21 and dial left, push rod 20 leaves the drive end 30 of lever 3, and the driven end 31 of lever 3 leaves the bonnet 6 of pressure limiting air bleeding valve, and the pressure limiting air bleeding valve is in non-exhaust condition.Pressure cooker can be cooked, and when the pot inner pressure of pressure cooker was increased to limit value, the pressed gas in the pot was with bonnet 6 jack-up, and the pressure limiting air bleeding valve begins exhaust, plays the effect of safe pressure limiting.After the cooking is finished, still have pressure in the pot, will stir handle 21 and dial to the right, the push rod 20 of switch control executive item 2 offsets with the end of lever 3 and the drive end 30 of activation lever 3 moves, and with bonnet 6 jack-up, the pressure limiting air bleeding valve is in exhaust condition.After pot inner pressure disappears, can uncap.Because it is far away that shifting part leaves the pressure limiting air bleeding valve, the operator can avoid steam to scald, and easy and simple to handle.
Above-described specific embodiment only is the utility model preferred embodiment, and the equivalent arrangements of being done according to the utility model claim all should be technology of the present utility model and contains such as.
