Problems solved by technology
[0003] In existing tire inflation guns, the opening and closing of the gas valve is mostly controlled by a solenoid valve. The power supply voltage required by the solenoid valve is relatively high, and the power supply voltage of the existing battery often does not reach the voltage required by the solenoid valve. In the case of normal opening or closing, it cannot work stably, and it will not be able to be used if the working time is too long, and its service life is short

Embodiment Construction
[0018] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0019] An embodiment of the present invention provides an air valve, such as figure 1 and figure 2 As shown, among them, figure 2 Perspective drawing is used, using dotted lines to indicate airflow channels. The air valve includes a valve seat 1, on which a first switch groove 21, an air inlet 11 and an air outlet 10 are provided, and the first switch groove 21, the air inlet 11 and the air outlet 10 can be set on the valve seat 1 on the same side, or on different sides. As shown in the figure, in order to optimize the structural design of the air flow channel, the first switch slot 21 and the air inlet 11 can be opened on the top of the valve seat 1 , and the air outlet 10 can be opened on the side of the valve seat 1 . The air inlet 11 is used for connecting the inflation equipment, and the air outlet 10 is used for connec...

The invention discloses an air calve and a tyre inflation gun. The air valve comprises a valve seat, and a first opening closing groove, an air inlet and an air outlet are formed in the valve seat; two first air passing holes are formed in the inner wall of the first opening closing groove; the two first air passing holes separately communicate with the air inlet and the air outlet; a first valvecore is arranged in the first opening closing groove; a first sealing gasket is connected to the first valve core in a sleeving manner; the first sealing gasket is fixed in the first opening closing groove; two first communication holes which are separately connected with the two first air passing holes are formed in the first sealing gasket; a penetrating first opening closing hole is formed in the first valve core; the two ends of the first opening closing hole are separately connected with the two first communication holes; a first driver is fixed to the valve seat; the first driver is usedfor driving the first valve core to rotate; when the first valve core rotates till the first opening closing hole is connected with the first communication holes, the air inlet communicates with theair outlet; and when the first valve core rotates till the first opening closing hole and the first communication holes are staggered, the air inlet and the air outlet are cut off. According to the air valve, the working state is stable, and the service life is long.
Description
technical field [0001] The invention relates to the technical field of air pressure valves, in particular to an air valve and a tire inflation gun. Background technique [0002] The tire inflation gun is an auxiliary device used when inflating tires. Its two ends are respectively connected to the inflator and the tire. When the air valve of the tire inflation gun is opened, the inflator can inflate the tire. When the air valve is closed, the tire inflation gun can Displays the current air pressure of the tire to inform the inflation status. [0003] In existing tire inflation guns, the opening and closing of the gas valve is mostly controlled by a solenoid valve. The power supply voltage required by the solenoid valve is relatively high, and the power supply voltage of the existing battery often does not reach the voltage required by the solenoid valve. In the case of normal opening or closing, it cannot work stably, and it will not be able to be used if the working time is...
