Description
Technical field
The utility model relates to a kind of control valve, specifically is a kind of control valve of pressure cooking appliance.
Background technology
At present, generally has pressure control switch in the outer pot of the electric pressure cooking appliance of people's use.A kind of electric pressure cooking appliance was disclosed on June 27th, 2007 like Chinese patent document number CN2914931; Comprise a pot body, outer pot, interior pot, pot cover, heat-generating disc, but pot cover and outer pot or pot body rigidity are fastened on one, are provided with sealing ring between pot cover and interior pot; Interior pot places on the heat-generating disc; Heat-generating disc is installed on the elastomer of outer pot bottom, is equiped with gauge tap on heat-generating disc or the elastomer, and corresponding gauge tap position is provided with catch bar on the outer pot; Wherein be equiped with touch part on heat-generating disc or elastomer or the gauge tap, be equiped with the cut-off switch that when gauge tap lost efficacy, can contact on outer pot or the catch bar with touch part.The assembly structure of this structure control switch and cut-off switch is comparatively complicated, and fault rate is higher.Therefore, need further to improve.
The utility model content
The purpose of the utility model aims to provide the control valve of a kind of simplicity of design, pressure cooking appliance rational in infrastructure, safe and reliable, applied widely, to overcome weak point of the prior art.
Press the control valve of a kind of pressure cooking appliance of this purpose design; Said pressure cooking appliance comprises that rigidity is fastened on the interior pot and the pot cover of one; Both form cooking cavity, and control valve comprises the valve body that is arranged on the cooking cavity, but its architectural feature is to be provided with the soft magnetic bodies that pogo stick and magnetic are lived pogo stick in the valve body; Pogo stick one end elasticity is arranged in the valve body, and an other end stretches out valve body.
Said pogo stick elasticity is arranged on a end in the valve body and is fixedly connected with the magnetic patch that magnetisable and magnetic is lived soft magnetic bodies.
Said pogo stick elasticity is arranged between interior end of valve body and the valve body and is provided with spring.
The end that said pogo stick elasticity is arranged in the valve body also is provided with the release link of stretching out valve body.
Said valve body is made by metal material.
The end that said pogo stick stretches out valve body links to each other with the switch of air bleeding valve or control circuit.
Said valve body is arranged on interior pot or the pot cover.
The utility model pressure cooking appliance is when normal the use, and the elastic force that the magnetic patch magnetization soft magnetic bodies in the control valve overcomes spring simultaneously holds soft magnetic bodies, and the motion of restriction pogo stick; When producing big pressure in the pressure cooking appliance, its internal temperature will constantly raise, and heat is passed to the inner soft magnetic bodies of control valve simultaneously; When the temperature of soft magnetic bodies is higher than its Curie point, the soft magnetic bodies demagnetization, magnetic force disappears; Under the effect of spring, drive pogo stick and upspring.This control valve can be applicable on the switch of air bleeding valve or control circuit of pressure cooking device, helps the potential safety hazard of eliminating pressure cooking appliance.Its simplicity of design, rational in infrastructure, safe and reliable, applied widely.

Fig. 2 is the user mode reference diagram of an embodiment.
Fig. 3 is the user mode reference diagram that an embodiment is connected with air bleeding valve.
Fig. 4 is the user mode reference diagram that an embodiment is connected with the switch of control circuit.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 4, the control valve of this pressure cooking appliance, said pressure cooking appliance comprise that rigidity is fastened on interior pot (not marking among the figure) and the pot cover 1 of one; Both form cooking cavity, and control valve comprises the valve body 2 that is arranged on the cooking cavity, wherein; The valve body 2 of present embodiment is arranged on the pot cover 1, and on the pot, it is changeable that it is provided with the position in it also can be arranged on by actual needs; As long as satisfy the condition of temperature in the sensitive perception culinary art of its ability cavity; But be provided with the soft magnetic bodies 4 that pogo stick 3 and magnetic are lived pogo stick 3 in the valve body 2, pogo stick 3 one end elasticity are arranged in the valve body 2, and an other end stretches out valve body 2.
Pressure cooking appliance is when normal the use, and the magnetic patch 5 in the control valve magnetizes soft magnetic bodies 4, and the elastic force that magnetic patch 5 overcomes spring 6 simultaneously holds soft magnetic bodies 4, limits pogo stick 3 motions simultaneously, and this moment, pogo stick was in "off" state, and is as shown in Figure 1.When producing big pressure in the pressure cooking appliance; The temperature of its inner cooking cavity will constantly raise, and heat is passed to the inner soft magnetic bodies 4 of control valve simultaneously, when the temperature of soft magnetic bodies 4 is higher than its Curie point; The magnetic force of soft magnetic bodies 4 disappears; Under the effect of spring 6, drive pogo stick simultaneously and upspring, this moment, pogo stick was in "open" state, and is as shown in Figure 2.After the pogo stick of control valve " is opened ", only need wait until that the temperature of control valve reduces, the temperature of soft magnetic bodies 4 is lower than its Curie temperature; Magnetic patch 5 gets final product remagnetize soft magnetic bodies 4, but because distance, the elastic force that the magnetic force of magnetic patch 5 still can not overcome spring 6 holds soft magnetic bodies 4; This moment must be with outer force urges release link 7; Make magnetic patch 5 and soft magnetic bodies 4 reduced distances, amount of magnetization increases, and magnetic force returns to the elastic force that can overcome spring 6 and holds soft magnetic bodies 4; Even after unclamping release link 7, still can keep "off" state.This control valve is the non-automatic valve that resets, and security is high.
If the end that pogo stick 3 stretches out valve body 2 links to each other with air bleeding valve 8, pogo stick 3 will drive air bleeding valve 8 and open so, and the exhaust of help cooking cavity is as shown in Figure 3.If the end that pogo stick 3 stretches out valve body 2 links to each other with the switch 9 of control circuit, it closes the circuit of heater 10 with driving switch 9 so, stops heater cooking cavity is continued to heat.
