The exhaust structure and its pressure cooker of a kind of pressure cookerTechnical field
The present invention relates to a kind of cooking utensils.Relate in particular to the exhaust structure and its pressure cooker of a kind of pressure cooker.
Background technology
Effect is good because it is cooked for electric pressure cooking saucepan, and speed is fast, the advantages of energy-conservation, has come into huge numbers of families, has become kitchenOne of indispensable living electric apparatus in room, is provided with a pot tooth above the electric pressure cooking saucepan of rotatable pot-cover-type, because its is goodlooking, structure letterIt is single, progressively become the leading products in market.
But, the problem of electric pressure cooking saucepan has hot difficult closing lid and inhales pot, in order to solve the above-mentioned technical problem, prior artIn electric pressure cooking saucepan solve to inhale pot and the problem of hot difficult closing lid by reducing electric pressure cooking saucepan external and internal pressure difference.
Chinese patent literature CN105476461A discloses a kind of electric pressure cooking saucepan, it include control circuit, pot, upper lid,Pot cover, pressure limiting valve and driving part, wherein, sliding mechanism, the pressure limiting valve are provided between the pressure limiting valve and the pot coverOn be provided with auxiliary section, the pot cover is covered on described when turning to the second place from first position, the driving part withThe auxiliary section is engaged to prevent the pressure limiting valve from rotating with the pot cover, while the pressure limiting valve is in the sliding machineIn the presence of structure, moved up along the blast pipe, so that the blast pipe is communicated with the external world.In addition, which also discloses describedOne in valve seat and the pressure limiting valve upper to have stud, and another is upper with guiding surface, and the end of the stud is resisted againstOn the guiding surface and can along the guiding surface slide rise, the sliding mechanism include stud and the guiding surface.That is the prior art is in pot cover Unscrew, and pot cover drives stud rotation, and driving part stops auxiliary section rotation, guiding surfacePressure limiting valve is moved axially upwards because of the rotation of stud, pressure limiting valve is opened.Because stud is fixed, thus is coordinatedPortion still can just be such that inclined-plane coordinates with stud in a small range rotation, drive pressure limiting valve to move up, therefore, stud is will be by gravityEffect, overcome be applied to frictional force thereon because pressure limiting valve rotates again, being used for a long time easily makes stud bend and then fail,Influence the service life of pressure cooker.
The content of the invention
Therefore, the pressure cooker that the technical problems to be solved by the invention are needs multiple part phases when opening pressure limiting valveMutually coordinate, stud is easily damaged, influence the service life of pressure cooker, and then provide a kind of row of the longer pressure cooker of service lifeDepressed structure and its pressure cooker.
In order to solve the above technical problems, a kind of exhaust structure of pressure cooker of the present invention, it includes
It is arranged on the pressure limiting valve on blast pipe, the pressure limiting valve and is fixedly installed pushing mechanism；
Locating part, is fixed on pot cover；
Drive component, the drive component drives the pushing mechanism；
The locating part limits the pressure limiting valve and is only capable of moving up and down along blast pipe axis, and the drive component driving is describedPushing mechanism is moved up and down along blast pipe axis.
The pushing mechanism includes the extension extended along exhaust tube axis direction and is fixed on the extension describedFixed part on pressure limiting valve, the extension and the spacing cooperation of the locating part.
The pressure limiting valve is integrally formed with the pushing mechanism.
The locating part is platy structure, and the through hole excessively passed through suitable for the pushing mechanism is formed thereon, described excessively logicalAxially bored line and the blast pipe diameter parallel.
The drive component includes
Power part, with output shaft；With
Actuator, it has the connecting portion being connected with the output shaft and drives the pushing mechanism along blast pipeThe drive division that axis is moved up and down.
The power part is moved horizontally along perpendicular to the exhaust tube axis direction.
The power part is electric pushrod, and it includes a housing and the ferroelectric core being arranged in housing, the ferroelectric coreIt is connected with the output shaft, the ferroelectric core exports power when the housing is powered, resetted when the housing is powered off.
Inclined-plane is provided with the drive division and/or the pushing mechanism, for moving horizontally the power partThe promotion pushing mechanism is converted to move up and down.
The actuator be two ends bend plate, its one end is connected with the output shaft, the other end can be along the outputWhat direction of principal axis was moved is arranged on the one end of the power part away from the output shaft.
The reset that the biasing force away from the output direction of principal axis is applied with to the actuator is provided with the actuatorPart.
The reset components are back-moving spring.
A kind of pressure cooker, it includes pot and covered to be provided with blast pipe on the pot cover in the pot, the pot cover,Any of the above-described exhaust structure is provided with the blast pipe.
The above-mentioned technical proposal of the present invention has advantages below compared with prior art,
In the exhaust structure of pressure cooker of the present invention, it includes being arranged on the pressure limiting valve on blast pipe, the pressure limitingPushing mechanism is fixedly installed on valve；Locating part, is fixed on pot cover；Drive component, the drive component driving is described to be promotedPart；The locating part limits the pressure limiting valve and is only capable of moving up and down along blast pipe axis, is pushed away described in the drive component drivingDynamic component is moved up and down along blast pipe axis, i.e., the pressure cooker exhaust structure in the present invention does not need stud, on pressure limiting valvePushing mechanism realizes moving up and down for pressure limiting valve, and pushing part need not bear the gravity of pressure limiting valve in itself, thus pushing partDo not allow flexible, damage, and then greatly improve its service life, and then improve the service life of pressure cooker.
