Embodiment 1

[0021] When the valve is closed, the switch is turned on, and when the valve is opened, the switch is closed. The principle is that when the valve is closed, the rotation angle of the connecting rod is in the 0 state. At this time, the conductive joints 32, 33 are all on the main sliding mechanism 34. When both ends are connected, it is the open state of the control switch.

[0022] When the rotation angle of the connecting rod is greater than 0° during the opening of the valve, the conductive connectors 32, 33 are on the insulator 31, and the contacts 32, 33 are not conducting. This is the closed state of the control switch.

Embodiment 2

[0024] When the valve is not fully open, the control switch is closed; when the valve is fully open at 90°, the control switch is open. When the valve is not fully open, the conductive joints 32 and 33 are on the insulator 31 at this time, and the two points of the contacts 32 and 33 are not conducting , which is the closed state of the control switch.

[0025] When the rotation angle of the connecting rod is 90°, the valve is fully opened, and the conductive joints 32 and 33 are on the main sliding mechanism 34. At this time, the two ends of the conductive joints 32 and 33 are connected, which is the opening of the control switch. state.

[0026] 3. The principle of the potentiometer switch is as follows:

[0027] When the valve was closed, the rotation angle of the connecting rod was 0°, and the conductive joints 44, 45 were on the insulator 41 outside the second conductive ring segment 44 and the third conductive ring segment 45, and the second conductive ring segment 44 a...

Abstract

The invention relates to an air intake and ignition integrated valve for a commercial gas cooker. A connecting rod is connected to the central part, and the central part is connected to a driven shaft outside the main part. The columnar surface of the driven shaft is provided with an insulating paint layer. There is a main sliding mechanism on the top, and a fixed contact cover is provided outside the driven shaft. The fixed contact cover is fixedly connected to the main body. The first and second conductive joints arranged up and down are arranged inside the fixed contact cover. The second conductive joints are in sliding contact with the ring-shaped cylindrical contact surface where the main sliding mechanism is located; the first and second conductive joints are respectively connected to the ignition control circuit through signal lines. The present invention integrates a microswitch of an ignition control device on the special valve for air intake, and automatically ignites the gas stove when the special valve for air intake is opened. The invention also integrates the micro switch for controlling the auxiliary peripherals of the gas stove, and produces the interlocking effect of the special valve for intake air and the external auxiliary equipment, so that the gas supply and the external equipment can achieve the best matching effect.

Description

technical field [0001] The invention relates to a commercial gas stove, in particular to an air intake and ignition control valve for a commercial gas stove. Background technique [0002] Refers to the large-scale burning appliances used by hotels, guesthouses, restaurants, restaurants, government agencies, schools, military, hospital canteens and other groups that use various gases such as petroleum gas and natural gas as energy sources to directly heat cooking utensils. Most of the existing commercial gas stoves adopt the method of separating the special valves for ignition and air intake. When using commercial gas stoves, the operator needs to hold down the ignition switch while opening the special valve for air intake, and operate with the cooperation of left and right hands. It is easy to produce the phenomenon that the ignition does not catch, or the phenomenon of ignition and deflagration, so it is very inconvenient to use, and there is also a certain potential safety...
