Embodiment one
Fig. 3 is the structural representation of gas range electropneumatic valve preventing dry fry embodiment one of the present invention.
As shown in the figure, wherein, switching device 4 comprises: push knob 41, be located at the move up and down pulse ignition switch of control and for being implemented in the anti-dry circuit controling switch of the knob rotation control that is pressed of connecting the anti-dry circuit when opening air valve of the knobs 41 that are pressed in the fixed mount 3.
The move up and down pulse ignition switch of control of the described knob that is pressed is: the described knob 41 pushed connects a depression bar 42, the affixed axle sleeve 43 in the end of described depression bar 42, described axle sleeve 43 is sheathed on the valve rod 11 of described air valve 1 relatively slidably, described axle sleeve 43 is provided with one and follows first pressing plate 44 that axle sleeve moves up and down, on described fixed mount 3 first pressing plate 44 below be provided with first microswitch 45, be provided with between the pedestal 12 of the valve body of described first pressing plate 44 and air valve 1 first the compression spring 46.
The anti-dry circuit controling switch of the described knob rotation control that is pressed: above described first pressing plate 44, the outside of axle sleeve 43 is provided with and can endwisely slips and with second pressing plate 47 of axle sleeve rotation along axle sleeve, be provided with the second compression spring 48 between described second pressing plate 47 and described first pressing plate 44, on described fixed mount 3, be provided with below second pressing plate 47 second microswitch, 49, the second microswitches 47 above be provided with clamp 50.
In the present embodiment, described second pressing plate 47 can be circular dull and stereotyped (as shown in Figure 4), it also can be half cam flat board as shown in Figure 8, be provided with the groove 471 of up/down perforation in the edge of circular flat board or half cam flat board, when pushing knob and be in dead-center position and press down, the described clamp of being located at above second microswitch 50 can see through from groove 471.For the half cam flat board, clamp also can be arranged at and push the place ahead that knob is in the dead-center position rotation this moment.
The described center that is fixed in the axle sleeve 43 of depression bar 42 ends has an axis hole 431, and the described axis hole 431 of knob 41 by described axle sleeve of pushing is slidedly arranged on the valve rod 11 of described air valve 1, is provided with between axis hole 431 and valve rod 11 and limits the two key in relative rotation; Or the axis hole 431 of described axle sleeve is square hole, and the top of described valve rod 11 is square shaft.The two can only slide after cooperating relatively, can not relatively rotate.
On described first pressing plate 44, be provided with the slide opening 441 that is sheathed on valve rod 11 tops, described first pressing plate 44 is resisted against the end face of described axle sleeve 43 by the first compression spring 46.
In the specific embodiment shown in Figure 3, the periphery of axle sleeve 43 is up big and down small stepped cylinder, describedly can endwisely slip and be provided with the circular axis hole slippery along axle sleeve with the axle sleeve small column with the circle of axle sleeve rotation or second pressing plate 47 of half cam flat board, step surface in axle sleeve is provided with card post 431, and described cam circular hole is provided with hole clipping 472 with respect to card post 431 positions.Wherein, the step surface of stepped cylinder is used to press down second pressing plate, and limits second pressing plate and go up sliding position most.The effect of card post 431 is relatively rotating between restriction second pressing plate 47 and the axle sleeve 43.
Fig. 5 is another embodiment that second pressing plate cooperates with axle sleeve.The outside of axle sleeve 43 ' shown in Figure 5 is a four-prism, describedly can endwisely slip and be provided with and the slippery square opening and prism of the quadrangular of axle sleeve periphery, be provided with the stop bit pin 432 (as shown in Figure 5) that restriction second pressing plate is gone up sliding position most in the outside of axle sleeve along axle sleeve with the circle of axle sleeve rotation or second pressing plate 47 of half cam flat board.
Fig. 6 is Fig. 3 embodiment gas range electropneumatic valve preventing dry fry fired state figure.
During igniting.Push knob 41, push knob 41 by depression bar 42 make axle sleeve axle 43 along valve rod 11 to lower slider, described axle sleeve 43 ends of being located at are sheathed on first pressing plate 44 on the valve rod 11 under axle sleeve promotes, the pressure follow axle sleeve that overcomes the first compression spring 46 moves downward, touch first microswitch 45, the pulse firing circuit is connected, and the electrode on the burner produces the electric spark combustion gas of igniting.
Second pressing plate 47 is also followed axle sleeve 43 and is moved downward, and be positioned at below second pressing plate 47 clamp 50 by be located at groove 471 on second platen edge be positioned at second pressing plate above.
Fig. 6 is the normal air feed burning position of Fig. 3 embodiment gas range electropneumatic valve preventing dry fry figure.
In the process of rotary push knob 41, second pressing plate 47 presses second microswitch 49, connects the anti-dry circuit.
Unclamp and push knob 41, first pressing plate 44, axle sleeve 43, depression bar 42 move on pushing knob 41 under spring 46 pressure effects, shoulder contact fixed mount 3 inner surfaces on the axle sleeve 43 and braking, first pressing plate 44 breaks away from microswitches 45, pulse firing down circuitry.
Second pressing plate 47 is with axle sleeve 43 rotation one angle, be positioned at above second pressing plate 47 clamp 50 can not from the groove on second platen edge 471 pass and get back to second pressing plate 47 below.Thereby second pressing plate 47 is stopped by clamp 50 can not to follow on the axle sleeve 43 to move, and continues to keep pressing second microswitch 49, promptly keeps the anti-dry circuit to connect in the time period of ventilation burning always.
Finish using, close fire, push knob 41 and get back to zero-bit, axle sleeve 43 drives 47 rotations of second pressing plate and gets back to zero-bit.The groove 471 at second pressing plate, 47 edges is got back to and clamp 50 corresponding home positions, and second pressing plate 47 no longer is subjected to clamp 50 to be stopped, gets back under the effect of second spring 48 above the clamp 50.Break away from second microswitch 49, the anti-dry circuit is cut off.
Embodiment two
The difference of present embodiment and embodiment one is the plate shaped pressing plate (comprising circular plate type or semicircle cam-shaped) that will press second microswitch from above, changes the semicircle cam that presses second microswitch from the side into.Specifically shown in Fig. 8,9, as seen from the figure, the described anti-dry circuit controling switch of pushing the knob rotation control that is pressed on the knob of being located at: above described first pressing plate 44, the outside of axle sleeve 43 is provided with can be with second pressing plate 51 of axle sleeve 43 rotations, on described fixed mount 3, the outside of second pressing plate 51 is provided with second microswitch 52, and described second pressing plate 51 is half cam that circumferential lateral surface has certain altitude.When pushing knob 41 and be in zero-bit, the side of semicircle cam does not contact with second microswitch 52, in case push knob 41 rotations, the side of semicircle cam presses second microswitch 52 immediately, makes and connects the anti-dry circuit.Unclamp even push knob rotation back,, push and also do not break away from after moving on the knob and the pressing of second microswitch 52 because semicircle cam circumferential lateral surface has certain altitude.Unless close fire, push knob and get back to zero-bit.
Present embodiment is compared with embodiment one, and structure is more simple, need not second spring and clamp.But the axiality to cam and axle sleeve requires height, otherwise inhomogeneous with contacting of microswitch in rotary course.
The external diameter of described axle sleeve forms a shoulder greater than the external diameter of depression bar between the two.Axle sleeve contact fixed mount 3 when resetting and spacing.
