Description
Technical field
The utility model relates to the technical field of electric pressure cooking saucepan, more particularly relates to the safety control of electric pressure cooking saucepan.
Background technology
Electric pressure cooking saucepan is more and more accepted by people because it is easy to use and energy-conservation, because electric pressure cooking saucepan belongs to pressure vessel, thereby the security of its use is the matter of utmost importance that must solve.The electric pressure cooking saucepan of prior art generally is to adopt in the heat-generating disc bottom of pressure cooker elastic device is set, and the bottom of elastic device is provided with a displacement flash switch; The displacement that the pressure expansion of interior pot produces is delivered to elastic device through heat-generating disc, thereby the displacement that elastic device produces is delivered to the power supply of flash switch control electric pressure cooking saucepan heat-generating disc, makes it to quit work.As number of patent application is 91100026, the applying date is on January 9th, 1991, denomination of invention is the disclosed technology of the application for a patent for invention of full seal automatic multifunctional electric cooker, it is by rigid arm on the right cylinder and elastic arm, the pot cover and the pot body that will have sealing ring compress sealing, and with an adjustable flash switch, the operating mode of the electric hot plate between control bottom of pot body and the elastic arm realizes the pressure control in the electric cooker and adjusts.The defective of said structure is that its structure is complicated, the cost height, and because pot inner pressure just is passed to flash switch by accessories such as heat-generating disc, elastic devices, thereby reaction pot internal pressure directly perceived, being prone to fault, Kong Zhi accuracy has much room for improvement simultaneously.
The utility model content
The purpose of this utility model is exactly that a kind of simple in structure, cost is low, control accuracy is high electric pressure cooking saucepan safety control is provided for the deficiency that solves prior art.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
This electric pressure cooking saucepan safety control comprises shift transmission part and flash switch, this safety control is arranged on the tapping of pot cover, the pot cover of tapping is provided with elastomer, shift transmission part is fixed on this elastomer, and pass perforate, and flash switch is arranged on displacement and transmits part top, and flash switch is connected with the control circuit of electric pressure cooking saucepan, the shift transmission part outer cover is connected to the securing member of fixedlying connected with pot cover, is provided with seal between elastomer and the pot cover.
Described elastomer is arranged on the pot cover inboard or the outside of tapping.
As further specifying of such scheme, described elastomer and pot cover are into a single integrated structure; Described elastomer can be a split-type structural with pot cover also, and they link together by securing member.
Described elastomer is a shell fragment.
Described elastomer can also be butterfly spring or corrugated sheet.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the safety control of electric pressure cooking saucepan is arranged on the pot cover, constitute by the elastomer of fixedlying connected, shift transmission part and flash switch etc. with pot cover, the directly variation of perception pot inner pressure, flash switch is connected with the control circuit of electric pressure cooking saucepan, control the break-make of power supply, the control accuracy height, simple in structure, cost is low.
Description of drawings
Fig. 1 is for being equipped with the utility model sectional structure schematic diagram.
The specific embodiment
By shown in Figure 1, the electric pressure cooking saucepan safety control, be arranged on the tapping of pot cover 1, tapping is provided with shift transmission part 2, and pass perforate, flash switch 3 is arranged on displacement and transmits part 1 top, flash switch 3 is connected with the control circuit of electric pressure cooking saucepan, and shift transmission part 2 outer cover are connected to the securing member 4 of fixedlying connected with pot cover 1, and the pot cover inboard of pot cover 1 tapping is provided with elastomer 5, elastomer 5 cross sections are matrix, into a single integrated structure with pot cover 1, be provided with seal 6 between elastomer 5 and pot cover 1 inboard, also be provided with steam vent 7 on the pot cover 1, can discharge a pot interior hot gas, to reduce pressure.Described elastomer 5 adopts shell fragment.
As other embodiment of the present utility model, described shell fragment and pot cover can also be split-type structural, and it also can be fixedlyed connected with the pot cover inboard; Also can fixedly connected with the pot cover outside; Seal also is arranged on the elastomer and the pot cover outside.
Described elastomer can also be butterfly spring or corrugated sheet.
During use, the displacement that the pressure expansion in the pot produces is delivered to elastomer, the displacement transmission that the elastomer compressive deformation produces, thereby through the shift transmission part position to the power supply of flash switch control electric pressure cooking saucepan, make it to quit work, directly perceived, control accuracy is high.
