As shown in fig. 7, the double rocker arm 6 is provided with a long arm 601, a short arm 602, a positioning hole 605, and a first hinge 603 and a second hinge 604 at both ends. The first hinge 603 and the second hinge 604 are embedded on the gland 10, so that the double rocker 6 can rotate around the axis.

As shown in fig. 2, the low-current solenoid valve 3 includes a seal spring 301 and a gasket 302.

As shown in fig. 1 to 7, when the knob 4 is pressed down, the knob rod 401 pushes the valve core push rod 8 to be inserted into the positioning hole 605 of the short arm rod 602, the short arm rod 602 drives the double rocker arm rod 6 to rotate anticlockwise, and simultaneously drives the long arm rod 601 to rotate, the long arm rod 601 lightly touches the sealing pad 302, at this time, the sealing pad 302 leaves the air outlet sealing surface 5, and simultaneously the sealing pad is pushed to the bottom against the force of the sealing spring 301 until the low current electromagnetic valve 3 adsorbs the sealing pad 302 under the electromagnetic force, so that the gas outlet channel 9 is opened. The gas flows into the bottom of the valve core 7 from the gas outlet channel 9 through the gap between the valve body 1 and the gland 10, and then the knob rod 4 rotates to drive the valve core 7 to adjust the gas flow, so as to control the gas to be sprayed to the burner from the first nozzle 101 and the second nozzle 102 for combustion.

As shown in fig. 2-4, the double rocker arm 6 is installed between the valve body 1 and the gland 10, the double rocker arm 6 can rotate around the first hinge 603 and the second hinge 604, when the low-current electromagnetic valve 3 is powered down, under the force of the sealing spring 301, the sealing gasket 302 is pushed to reset, the gas outlet channel 9 is closed, and meanwhile, the sealing gasket 302 also pushes the long arm 601 on the double rocker arm 6, so that the double rocker arm 6 rotates clockwise to reset.

As shown in fig. 5-7, the valve core push rod 8 is sleeved in the valve core air passing hole 702 of the valve core 7 in an empty mode, when the valve core push rod 8 moves downwards, the sealing ring 11 is driven to move downwards, fuel gas enters the valve core ignition hole 703 through the valve core air passing hole 702 to ignite, the short arm rod 602 is provided with the positioning hole 605, the valve core push rod 8 is inserted into the positioning hole, when the valve core push rod 8 moves downwards, sliding is avoided, the rotation angle stability of the double rocker arm rod 6 is ensured, the stroke of the sealing gasket 302 is ensured to be a fixed value each time, the low-current electromagnetic valve 3 can ensure the suction sealing gasket 302 each time, and the air outlet channel 9 is opened.

In some embodiments of the utility model, the gas cooker adopting the low-current electromagnetic valve has the working principle that gas enters a gas inlet channel from a gas inlet, when a knob rod is pressed down, the knob rod touches a travel switch or a contact switch, the knob rod pushes a valve core push rod, then the valve core push rod pushes a short arm rod, the double-rocker arm rod rotates around an axle center and drives a long arm rod to touch a sealing gasket of the low-current electromagnetic valve, the sealing gasket moves to a suction position in a separation way from a sealing surface, meanwhile, a control valve sends an electric signal to an electric controller, the electric controller outputs the electric signal to the low-current electromagnetic valve, and the low-current electromagnetic valve sucks the sealing gasket against the force of a sealing spring under the driving of electromagnetic force, so that the gas outlet channel is opened. The gas flows into the bottom of the valve core from the gas outlet channel through the gap between the valve body and the gland, and then the knob rod rotates to drive the valve core to adjust the gas flow, so that the gas is controlled to be sprayed from the first nozzle and the second nozzle to the burner for combustion, namely the ignition work of the kitchen range. The gas control valve can be matched with an electric controller and a flame ion probe to be applied to a gas appliance to control a gas switch.

When the low-current electromagnetic valve is powered off, under the action of the spring force of the sealing spring, the sealing gasket is pushed to reset to close the gas outlet channel, and meanwhile, the sealing gasket also pushes the long arm rod on the double rocker arm rod to enable the double rocker arm rod to rotate and reset clockwise. Because the movement stroke of the sealing gasket is a fixed value when the low-current electromagnetic valve is opened, the sealing gasket cannot be sucked if the stroke is small, the stroke must be accurate, and the gas channel cannot be opened otherwise. The stroke is affected by the fact that the valve core push rod swings when moving downwards and slides when contacting the short arm rod, so that the stroke precision is not a fixed value, and the duration is short. In order to prevent the valve core push rod from sliding when pushing the short arm rod, a locating hole is formed in the contact surface of the short arm rod and the valve core push rod, so that the valve core push rod is inserted into the locating hole, and the defect that a sealing gasket of a hand-push type low-current electromagnetic valve cannot be opened due to the fact that the sealing gasket is not touched in place is overcome. The stroke of the sealing gasket is more accurate, the sliding is avoided, the stroke of the sealing gasket becomes a fixed value when the sealing gasket moves, and the defect that the sealing gasket of the low-current electromagnetic valve cannot be opened because the sealing gasket of the low-current electromagnetic valve is not touched in place is overcome. Therefore, the original electromagnetic valve can be replaced by a low-current electromagnetic valve, and the power consumption is reduced.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
