[0049] The working principle of the valve body of the gas stove is as follows: the child lock positioning sheet 3 is pressed down by the pressing shaft 2, so that the horizontal height of the child lock positioning sheet 3 is lower than the horizontal height of the bottom of the second limiting block 804, the child lock switch is unlocked, the child lock positioning sheet 3 is moved away from the limiting groove 806 by rotating the pressing shaft 2 counterclockwise, the push plate 301 pushes the push rod 401 of the needle lever 4 to rotate, and the top rod 402 at the other end of the needle lever 4 is rotated, the electromagnetic valve needle 6 is pushed to move towards the electromagnetic valve 5 by the top rod 402, the sealing rubber gasket 501 is pushed away, the gas outlet of the first gas inlet passage 104 is opened, and the gas can flow from the first gas inlet passage 104 to the second gas inlet passage 105; meanwhile, the valve core 9 is also rotated by the rotation of the pressing shaft 2, the flow regulating hole 903 on the valve core 9 is opened, the second gas inlet passage 105 is connected, the gas flows through the flow regulating hole 903 of the valve core 9, flows to the first gas outlet passage 106 and the second gas outlet passage 107, and flows to the burner of the gas stove.

[0050] As described above, the pressing shaft 2 is pressed down until the sealing rubber gasket 501 of the electromagnetic valve is opened, if the force applied to the pressing shaft 2 is cancelled, the pressing shaft 2 and the child lock positioning sheet 3 are reset by the action of the valve core spring 10, the electromagnetic valve needle 6 is reset by the action of the needle spring 7, the sealing rubber gasket 501 of the electromagnetic valve 5 is reset, and the gas outlet of the first gas inlet passage 104 is closed.

[0051] When igniting a gas stove, press down on the rotating shaft to open the valve core to a predetermined angle. Generally, a dedicated limit switch is set inside the valve body to stop the rotating shaft from rotating, usually set to around 90 degrees. This utility model relates to a gas stove valve body. The rotating shaft 2 is pressed down and rotates to open the valve core to a predetermined angle, without the need for a dedicated limit switch to stop its rotation. The action is as follows: The pressing down of the rotating shaft 2 causes the child lock positioning piece 3 to press down, making the horizontal height of the child lock positioning piece 3 lower than the horizontal height of the bottom of the second limit block 804. After unlocking the child lock switch, the rotating shaft 2 is rotated counterclockwise to make the child lock positioning piece 3 leave the limit groove 806. After the child lock positioning piece 3 rotates, the lever 301 pushes the lever 401 of the pin lever 4 to rotate, and also causes the push rod 402 at the other end of the pin lever 4 to rotate. Through the push rod 402, the solenoid valve pin 6 is pushed towards the solenoid valve 5, pushing the sealing gasket 501 to move away. After moving away to the maximum stroke of the solenoid valve 5, the solenoid valve pin 6 encounters resistance and cannot be pushed further. Correspondingly, the rotating shaft 2 also encounters resistance during the transmission process, causing the rotating shaft 2 to stop rotating. The angle at which the rotating shaft 2 stops rotating is generally set to about 90 degrees, which can be adjusted by adjusting the dimensions of the components involved in the transmission.

[0052] The gas stove valve body involved in this utility model uses a downward-pressing rotating shaft 2 to drive a locking plate 3, which in turn actuates a pin lever 4 mounted on the valve body housing 1. When the pin lever 4 rotates, it moves the solenoid valve pin 6, pushing the sealing gasket 501 of the solenoid valve 5 to move. When the sealing gasket 501 moves to its maximum stroke, there is no need for a dedicated limit to stop the rotating shaft 2 from rotating; the shaft 2 stops rotating due to resistance, simultaneously opening the air intake channel to allow gas flow. Since the driving pin lever 4 is mounted on the valve body housing 1, there is no need for a lever seat and a lever sealing gasket. This not only reduces material costs and enhances the product's market competitiveness but also reduces a sealing component, thereby reducing the probability of gas leakage, improving the product's pass rate, reducing the cost of defective products, and further enhancing the product's market competitiveness.
