working principle: when a chef cooks dishes, firstly, a fire valve is opened to enable fuel gas to be introduced into a fire gas pipe, then an electronic igniter is driven by an ignition switch to ignite, after ignition is successful, the fire gas pipe is opened to form long open fire, then a fan is started by a fan switch, finally a main air valve is opened, at the moment, a movable plate 14 is at the lowest end under the action of a second spring 16, a second connecting rod 41 pushes a magnetic block 13 and a connecting frame 11 to move to be close to the inner top surface of a second shell 6, a first spring 12 is compressed, a driving rod 10 extends into the control valve 4, the control valve 4 blocks ventilation, a used lower limit rod 28 of a fourth spring 30 is far away from the connecting frame 11, and a first wedge 31 is attached to the inclined surface part of a second wedge 35; the state of the economizer 3 is shown in fig. 6 and 7, and at the moment, the main fire gas pipe orifice is not ventilated, and the main fire in the hearth 2 is not ignited.

After a cook puts a pot on the hearth 2, the pot presses on the arc plate 181 to enable the pressing plate 18 to rotate, one end of the pressing plate 18 away from the hearth 2 is used for poking the movable plate 14 upwards, the movable plate 14 moves upwards to compress the second spring 16, in the process that the movable plate 14 compresses the second spring 16, the second connecting rod 41 is separated from contact with the magnetic suction block 13, the first spring 12 pushes the driving rod 10 to extend outwards, the control valve 4 is smooth in gas transmission, the main fire pipe orifice is ventilated, main fire is ignited under the action of the open fire, in the process that the movable plate 14 moves towards the inner top surface of the first shell 5, the pushing linkage 32 is driven to integrally move, the inclined surface attaching part of the first wedge block 31 and the second wedge block 35 is bigger and bigger, the fourth spring 30 is compressed, the first wedge block 31 moves towards the connecting frame 11, when the limit rod 28 approaches the connecting frame 11, the limit rod 39 is opposite to the limit rod 28, the connecting frame 11 is kept in a static state, then the limit rod 28 continues to move to be matched with the limit rod 39, the T-shaped rod 34 is poked to be in contact with the state of the energy-saving device 3 and the energy-saving device shown in fig. 8 and 9.

When a cook is frying dishes, the pot is always pressed on the periphery of the hearth 2 by means of the periphery of the hearth 2 and is also pressed on the arc plate 181, the pot is close to the magnetic attraction block 13 of the energy saver 3 when the cook is overturned, even if the pot generates attraction force to the magnetic attraction block 13 and the pot briefly touches the gland 7, the limiting connecting frame 11 is limited to move due to the fact that the limiting rod 28 is matched with the limiting hole 39, and when the gland 7 is pressed, the limiting rod 28 is delayed to move so that the limiting rod 28 is temporarily touched to the gland 7, the limiting rod 28 is not completely separated from the limiting hole 39, the control valve 4 is still in a smooth state in the process, and main fire in the hearth 2 keeps normal fire.

When a cook adds side dishes or prepares seasonings, the pot is dragged to the hearth 2 and the energy saver 3, at the moment, the pot is pressed on the pressing cover 7 while being pressed on the arc plate 181, the pressing cover 7 compresses the third spring 26 while being pressed on the pressing cover 7, the nut 21 is driven to move away from the top surface of the second shell 6, the screw rod 20 is driven to rotate, the rotating disc 22 rotates to enable the stirring rod 23 to push the T-shaped rod 34, the sliding seat 33 moves along the sliding groove towards the direction away from the connecting frame 11, the thrust plate 36 pushes the first wedge block 31 to move, the fourth spring 30 stretches, the limiting rod 28 exits the limiting hole 39, the movement of the connecting frame 11 is not limited, the pot attracts the magnetic attraction block 13 to drive the connecting frame 11 to move, the first spring 12 is compressed, the driving rod 10 moves into the control valve 4, the valve of the control valve 4 is closed, main fire in the hearth 2 is extinguished, and the state diagram of the energy saver 3 is shown in fig. 10 and 11. The above-mentioned start when putting the pot on furnace 2 and economizer 3, because the effect of lead screw 20 in the economizer 3 and spring makes the flameout often have certain delay, just can guarantee at this moment that when putting the pot again on furnace 2 in the prescribed delay time, the main fire will not go out.

After the chef adds the dish or the seasoning, the pot is pushed into the hearth 2 again, at the moment, the gland 7 moves upwards under the action of the third spring 26, the magnetic attraction block 13 is not attracted, the air transmission of the control valve 4 is smooth under the action of the first spring 12, the limit hole 39 on the connecting frame 11 corresponds to the limit rod 28, the screw rod 20 is driven to rotate reversely by the nut 21, the rotating disc 22 and the toggle rod 23 rotate reversely, the sliding seat 33 moves towards the connecting frame 11 under the action of the fifth spring, the limit rod 28 stretches into the limit hole 39 under the action of the fourth spring 30, the state diagram of the energy saver 3 is shown in fig. 6 and 7, and the process has the process of delaying ignition. When the cook leaves the pot end or washes the pot after cooking, the gas supply of the control valve 4 is interrupted, and the state of the energy economizer 3 is restored to the initial state, as shown in fig. 6 and 7.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and those skilled in the art should appreciate that the technical scheme and the inventive concept according to the present invention are equivalent or changed within the scope of the present invention.
