Abstract
The invention provides a delayed closing device for an electric pressure cooker. A flexible closing pad with a sealing cavity is arranged on the outlet of an air outlet pipe, a temperature control piece is arranged on the back of the flexible closing pad, a gap for forming a ventilation channel is reserved between the closing portion of the flexible closing pad and the outlet of the air outlet pipe, and the size of the gap is set in the mode that when the set time is up, the flexible closing pad and the temperature control piece encounter thermal deformation and cover the outlet of the air outlet pipe. A spring is connected between the flexible closing pad and the air outlet pipe, and the elasticity of the spring pushes the flexible closing pad to leave the outlet of the air outlet pipe. The delayed closing device has the advantages that a temperature controller is completely isolated from the air, control is executed according to the thermal contraction principle, the spring abuts against the closing pad to control the opening and closing time accurately, and use is safe and reliable.

Technical field
The present invention relates to the safety device of electric pressure cooking saucepan, more particularly to a kind of electric pressure cooking saucepan time-delay closing device.
Background technology
The applicant had applied for the electric pressure cooking saucepan time-delay closing device of correlation, this kind of time-delay closing device, using temperature control
Switch carries out time control, although can change the rice process that boils, rational in infrastructure simple, and processing and manufacturing and assembly cost are low, but
As temperature detect switch (TDS) is connected with gas outlet, dampness occur affects to occur losing into the temperature detect switch (TDS) factor such as cause temperature detect switch (TDS) to make moist
The problems such as spirit, delay of response.
The content of the invention
It is an object of the invention to provide one kind by temperature controller completely and air insulated, and using shrinkage thermal expansion principle reality
Control is applied, sealing pad is withstood with spring, with precise control switch time, safe and reliable electric pressure cooking saucepan time-delay closing dress
Put.
The solution of the present invention is such：
A kind of electric pressure cooking saucepan time-delay closing device, the device include that escape pipe is exported, it is characterised in that：The escape pipe goes out
The flexible closure pad with sealing cavity is provided with mouthful, flexible closure acting as a cushion portion is provided with temperature control chip, the flexible closure pad
The gap to form venting channels is left between closing portion and escape pipe outlet, the size in the gap is set in when reaching setting
Between when the flexible closure pad and temperature control chip produce thermal deformation cover escape pipe outlet；Connect between flexible closure pad and escape pipe
Spring is connected to, the elastic force of the spring is exported to promote flexible closure pad to leave escape pipe.
More specifically technical scheme also includes：The formation of described sealing cavity is included sealing flap and is connected with sealing flap
The flexible closure pad for connecing, the periphery of the flexible closure pad are connected with the seal receptacle cover seal by sealing seat, its inner chamber shape
Into described sealing cavity.
Further：Described sealing flap is provided with sealed step, and sealing seat is connected with sealed step, described soft
Property sealing pad periphery be positioned at sealed step, above with sealing flap be connected, be connected with sealing seat below, with threaded connection
Structure screwing hermetic flap and sealing seat, the periphery of flexible closure pad is fastened to form sealing cavity.
Further：Described flexible gasket is overall band cavity structure, and its cavity forms described sealing cavity.
Further：Described flexible closure pad for the escape pipe closing portion closed of outlet be planar shaped,
Arc surfaced, spheric, one kind of taper.
It is an advantage of the invention that temperature controller is completely and air insulated, and implements to control using shrinkage thermal expansion principle, bullet is used
Spring withstands sealing pad, with precise control switch time, safe and reliable.

Specific embodiment
A kind of electric pressure cooking saucepan time-delay closing device, the device include the escape pipe outlet 6 for being fixed on pot cover 1, the outlet
The flexible closure pad 10 with sealing cavity is provided with pipe outlet 6,10 back of flexible closure pad is provided with temperature control chip 9, described soft
Property sealing pad 10 closing portion and escape pipe outlet 6 between leave the gap to form venting channels, the size in the gap sets
When setting time is reached, the flexible closure pad 10 and temperature control chip 9 produce thermal deformation and cover escape pipe outlet 6；In flexible envelope
Close and between pad 10 and escape pipe 2, be connected with spring 11, the elastic force of the spring 11 leaves escape pipe for promotion flexible closure pad 10
Outlet 6.
Described sealing flap 7 is provided with sealed step, and sealing seat 5, the flexible closure are connected with sealed step
The periphery of pad 10 is positioned at sealed step, is connected with sealing flap 7 above, is connected with sealing seat 5 below, with threaded connection knot
Structure screwing hermetic flap 7 and sealing seat 5, the periphery of flexible closure pad 10 is fastened to form sealing cavity.
The structure of sealing cavity can be overall structure, i.e., described flexible gasket 10 is tied to be integrally formed band cavity
Structure, its cavity form described sealing cavity.
Described flexible closure pad 10 for 6 closing portions closed of escape pipe outlet be planar shaped, arc surfaced,
Spheric, one kind of taper.
It is Split type structure with flexible closure pad 10 that temperature control chip 9 is, temperature control chip and flexible closure pad are placed on sealing seat 5 with sealing
In flap 7, it is in clamping connection with buckle.
The course of work of the present invention is presented herein below：
Electric pressure cooking saucepan is heated, and the steam in pot is discharged by escape pipe outlet 6, exhaust duct 12, is produced when steam passes through
Heat transfer is to flexible gasket 10, the heat transfer produced during heating to flexible gasket 10 and temperature control chip 9, flexible gasket
Air heats in 10 sealing cavities below start to splash and rise, and promote the sealing surface of flexible closure pad 10 to export at 6 towards escape pipe
Mobile, with the increase of heat time heating time, when temperature reaches design temperature, temperature control chip 9 produces elastic deformation, by flexible closure pad
Position of the 10 sealing surface top to escape pipe outlet 6, as shown in Fig. 2 the gas in closing pot, into heating and the vexed meal shape of pressurize
State.After heat time heating time terminates, the temperature in pot slowly declines, and the temperature in sealing cavity after flexible gasket 10 is also followed down
