The automatic obturating system of pressure cookerTechnical field
The utility model relates to a kind of pressure cooker, particularly relates to the automatic obturating system of a kind of pressure cooker.
Background technology
Existing pressure cooker, particularly auto-electronic pressure cooker, when pot inner pressure reaches setting value, i.e. outage automatically, food can not get fully boiling and rolls in pot, and its cooked food mainly is " to boil in a covered pot over a slow fire " by high temperature pressure in the pot to boil.No matter boil, boil in a covered pot over a slow fire, stew, stew etc., boil entirely lean on high temperature " to boil in a covered pot over a slow fire ", function singleness, thereby its taste of food that " boiling in a covered pot over a slow fire " cooks is defective.
The utility model content
Solution of the present utility model is such: be connected with hollow tube on pressure cooker lid, be placed with air valve in hollow tube, stretch out the flexible member that the hollow tube position has its elasticity that air valve is ejected at air valve; Be connected with the warm seat of biography on the pressure cooker lid top, passing the limited temperature sheet of installation on warm; Have pin-lift arrangement, an end of described pin-lift arrangement is connected with the warm sheet of limit, and the other end joins at the normal temperature position and the air valve of the warm sheet of limit.
After adopting abovementioned technology, trip is to catch on air valve during owing to normal temperature, and when food in the pot seethed with excitement, air valve can not move, close gas check valve, have only when kettle temperature is delivered to and limit warm sheet, cause the warm sheet distortion of limit, push trip, discharge air valve, air valve just can move upward, and realizes holding one's breath automatically.Owing to through the time-delay of a period of time, limit warm sheet just to control trip and discharge air valve, make institute's cooking food increase by one section process that boiling is rolled.
The utility model has the advantages that to make food in pot, obtain the process that one section boiling is rolled, just close gas check valve automatically, more meet the food custom that boils, safe and convenient to use reliable.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanyingdrawing 2 is the utility model structural representations when normal temperature.
Accompanying drawing 3 is the utility model structural representations when holding one's breath.
The specific embodiment
Present embodiment includes pot body 1,fluid sealant 2, biography temperature seat 3, air valve 4, spring 5, trip 6, trip spring 7, push rod 8, the warm sheet 9 of limit, temperature limiter shell 10, hollow tube 11,housing 12.
Stretch out the flexible member 5 that hollow tube 11 positions have its elasticity that air valve is ejected at air valve 4; Be connected with the warm seat 3 of biography on the pressure cooker lid top, passing the limited temperature sheet 9 of installation on warm 3; Have pin-lift arrangement, an end of described pin-lift arrangement is connected with the warm sheet 9 of limit, and the other end joins at the normal temperature position and the air valve 4 of the warm sheet 9 of limit.
The bottom of biography temperature seat 3 is connected with pot cover, in order to receive the heat that transmits from pot cover, has by the insulation material enclosed cavity on biography temperature seat 3, limits warm sheet 9 to be positioned in the cavity.
In the present embodiment, described pin-lift arrangement has and the push rod 8 that is connected of the warm sheet 9 of limit, and trip 6 one ends of an end of push rod 8 and swing join, the other end of trip 6 when limitting the normal temperature position of warm sheet 9 and air valve 4 join.
Described air valve 4 stretches out hollow tube 11 1 ends boss, and described flexible member 5 is a spring, is socketed in the outer end of hollow tube 11.
The raised head face position of described air valve 4 and the screens of trip 6 adapt, and trip 6 is that the boss end position and the air valve 4 that are stuck in air valve 4 join.
Described trip 6 is connected with trip spring 7.
Except that sentencing, temperature-sensitive is coated with on every side insulation material at the warm sheet 9 of limit.
Single unit system is installed in thehousing 12, has only an end of air valve 4 to stretch out inhousing 12.
When normal temperature, limit warm sheet 9 position as shown in Figure 2, at this moment, under the elastic force effect of trip spring 7, an end of trip 6 blocks the upper end of air valve 4 boss, and air valve 4 can not be moved upward.When kettle temperature is heated to design temperature, pot inner pressure withstands air valve 4, make it upwards mobile top power, through the time-delay of a period of time, when heat by after passing temperature seat 3 heat being delivered to the warm sheet 9 of limit, the distortion that heat-transfer disc 9 produces as shown in Figure 3, push trip 6 and turn to the position that breaks away from the air valve boss, discharge air valve 4, air valve 4 moves upward under pot inner pressure pushes, and realizes holding one's breath automatically.
