Gas valve and gas stove comprising same

Abstract

The utility model provides a gas valve and a gas stove comprising the same. The gas valve comprises a first valve rod and a valve element, the first valve rod is used for rotary ignition and connected to the valve element, the gas valve further comprises a second valve rod and a transmission structure, and the second valve rod is connected to the first valve rod through the transmission structure, so that when the second valve rod is rotated, the first valve rod rotates at the same time, and gas is released; when the second valve rod is pressed, the first valve rod moves towards the valve element at the same time, and ignition is triggered. The opening process of the gas valve can be opened by pressing and rotating the second valve rod. Due to the fact that the axis of the second valve rod does not coincide with the axis of the first valve rod, liquid such as overflow liquid cannot continuously flow inwards to the valve element along the axis when flowing into the stove panel through the gap between the stove panel and the peripheral side of the second valve rod, the possibility that water enters the valve body is reduced, the maintenance rate is reduced, and the service life of the gas stove is prolonged.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooking utensils, in particular to a gas valve and a gas stove comprising the same. BACKGROUND

[0002] In the prior art, the maintenance rate of the gas valve of the gas stove is relatively high, which is usually caused by the leakage of the overflow liquid to the valve core during daily use, resulting in the rusting of the key components in the valve core and affecting the performance of the valve body, thereby causing the high maintenance rate of the valve body. Currently, the waterproof measures taken against the overflow liquid easily leaking from the surface of the panel to the valve core to cause water ingress mainly include installing a waterproof sleeve or other parts below the knob of the panel to prevent water from entering the panel, or installing a waterproof rubber sleeve on the valve rod of the valve body to prevent water from entering the interior of the valve body. Although the above-mentioned solutions can prevent water from entering, due to the existence of assembly tolerance gap, part of the water still enters the gap between the panel and the valve rod, and then flows downward to the valve core.
