Specific embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the application can phaseMutually combination.
As shown in Figure 1 to Figure 3, the cooking apparatus of the present embodiment includes：Pot, pot cover 10, are described in detail exhaust pipe 20The utility model.Pressure limiting valve module 30 and driving mechanism.Wherein, pot is holding food to be cooked；The lid of pot cover 10 is setIn pot, pot cover 10 include pot cover body 11 and with 11 integrally formed air vent seat 12 of pot cover body.Exhaust pipe 20 is setIt puts on pot cover 10, and positioned at the inside of air vent seat 12, exhaust pipe 20 has exhaust passage 21.Pressure limiting valve module 30 is arrangedOutside exhaust pipe 20, pressure limiting valve module 30 has the block-up position of closure exhaust passage 21 and opens the row of exhaust passage 21Gas position.Driving mechanism to pressure limiting valve module 30 apply external force, pressure limiting valve module 30 under the effect of external force with air vent seat 12Coordinate so that from exhaust position is moved to, when driving mechanism does not apply external force to pressure limiting valve module 30, pressure limiting valve module 30 existsBlock-up position is reset under the action of its own gravity.
Using the technical solution of the present embodiment, cooking apparatus includes pot cover 10, pot cover 10 include pot cover body 11 and with11 integrally formed exhaust pipe 20 of pot cover body, exhaust pipe 20 are located at the inside of exhaust pipe 20.Pressure limiting valve module 30 is outsideWith 20 cooperations of exhaust pipe so that pressure limiting valve module 30 is moved to exhaust position, when driving mechanism is not to pressure limiting valve under the action of powerWhen component 30 applies external force, pressure limiting valve module 30 is reset to block-up position under the action of its own gravity.In said structure,Due to exhaust pipe, 20 are integrally formed with pot cover 10, avoid and generate inconsistent phenomenon when installing exhaust pipe 20, so as toImprove the quality of product.Further, since need not again to exhaust pipe 20 assemble, therefore improve product production effectRate reduces production cost, solves the problems, such as the low production efficiency of cooking apparatus of the prior art.
As shown in Figure 1 to Figure 3, in the present embodiment, air vent seat 12 be protrude from pot cover body 11 enclose muscle, enclose muscle and limitGuide frame is provided between pressure valve component 30, when pressure limiting valve module 30 is subject to external force, pressure limiting valve module 30 is in guide frameLead the exhaust position being moved downward to away from exhaust pipe 20.Said structure is simple, easy to process.
As shown in Fig. 1 to Fig. 3, Fig. 6 and Fig. 7, in the present embodiment, guide frame is oblique including being arranged on the guiding enclosed on muscleFace 121 and the convex ribs 311 being arranged on 30 outer wall of pressure limiting valve module.Said structure is simple, easy to process.Specifically, limit is worked asWhen pressure valve component 30 is located at block-up position, convex ribs 311 are located at the bottom of guiding surface 121.When pressure limiting valve module 30 is subject to external forceUnder the action of and when rotating, the bottom of convex ribs 311 will coordinate with guiding surface.Since the bottom of convex ribs 311 is with guiding surfaceGradually move up, therefore the pressure limiting valve module 30 with the convex ribs 311 also gradually moves upwards, so as to open exhaust passage21, realize exhaust.And when pressure limiting valve module 30 is no longer influenced by external force, pressure limiting valve module 30 has downward under gravityThe trend of movement.At this point, the bottom of convex ribs 311 will coordinate with guiding surface, and it is gradual along guiding surface under gravityIt moves obliquely, until pressure limiting valve module 30 returns back to block-up position.It should be noted that above-mentioned guiding surface can bePlane can also be arcwall face.
