The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of pot cover.
Referring to figs. 1 through Fig. 3, Fig. 1 is the structural representation of the utility model pot cover; Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1; Fig. 3 is the cross-sectional view of the utility model pot cover.
In the utility model embodiment, this pot cover can be applicable on the pan such as electric cooker or pressure cooker.The pressure limiting valve 20 that this pot cover comprises inner cap 10, arranges on this inner cap 10, and the electromagnet 30 arranging on this inner cap 10, wherein, between electromagnet 30 and pressure limiting valve 20, be provided with the push rod 40 for promoting pressure limiting valve 20, on inner cap 10, be provided with accommodating cavity, electromagnet 30 is contained in this accommodating cavity, and the sidewall of this accommodating cavity is provided with the through hole that runs through the sidewall of accommodating cavity for push rod 40.This electromagnet 30 can be according to the opened/closed of the control signal control pressure limiting valve 20 of temperature sensor, pressure sensor or active chip.When needs exhaust makes, electromagnet 30 is controlled push rod 40 and is promoted pressure limiting valve 20, and pressure limiting valve 20 is opened; After venting completes, electromagnet 30 is controlled push rod 40 and is retracted, and now pressure limiting valve 20 recovers closure state under its Action of Gravity Field.
Technical solutions of the utility model promote pressure limiting valve 20 by electromagnet 30 and push rod 40, thereby control the opened/closed of pressure limiting valve 20, without people's direct control, have also just stopped the danger of being scalded by high-temperature gas.In addition, electromagnet 30 can, according to temperature sensor, pressure sensor or initiatively other the control signal work such as chip, make to control pressure limiting valve 20 more accurate, realizes the automatically controlled automation of pan.
Based on appeal embodiment, between push rod 40 and through hole, also can be provided with the elastic seal ring 50 for sealing push rod.The electromagnet 30 that is arranged so that of this elastic seal ring 50 is isolated from the outside, and has avoided the steam in pot to enter in electromagnet 30, has guaranteed that electromagnet 30 can work in dry environment, thereby has guaranteed the stability that electromagnet 30 is worked.
