Description

Air valve, air valve assembly and inflatable product The present application claims priority from the chinese patent office, application number 202422739573.8, application name "a gas valve" filed on day 08 11, 2024, which is incorporated herein by reference in its entirety. Technical Field The utility model relates to the field of ventilation devices, in particular to a gas valve, a gas valve assembly and an inflatable product. Background Existing products in the market include inflatable mattresses and air valves applied to inflatable mattresses. With the increasing demands of people for quality of life, there is an increasing demand for inflatable products, especially inflatable mattresses and inflatable sponge mattresses, in order to avoid the need for the user to perform an air-supplementing operation on the inflatable product several times during use, for which reason an air valve with better sealing performance, which is applied to inflatable mattresses, such as TPU inflatable sponge mattresses, i.e. inflatable mattresses made of Thermoplastic Polyurethane (TPU) materials, has been developed. The main problems of the existing products are that the existing air valve can seal the inflatable product and can be connected with the air pump to inflate the inflatable product, but the sealing performance of the air valve is poor, and when the inflatable product is deflated, the air can flow back into the inflatable product, so that the air in the inflatable mattress cannot be completely discharged, and a user needs a larger space to store the inflatable product when the user does not use the inflatable product. Disclosure of utility model The utility model aims to solve the problem of poor sealing performance of the existing air valve. The utility model provides an air valve, an air valve assembly and an inflatable product, which can stabilize the sealing effect. In order to solve the above technical problems, an embodiment of the present utility model discloses an air valve, including: A valve body; A valve seat connected with the valve body to form a fluid passage; a first seal disposed between the valve body and the valve seat; A valve spool including a vent in communication with the fluid passage, the valve spool rotatably disposed within the fluid passage relative to the valve seat and surrounded by the first seal to switch the valve spool between a first position and a second position; the valve core is in contact with the inner wall of the fluid channel in the first position, the first sealing element is in contact with the valve core and seals the valve core and the inner wall of the fluid channel, the valve core is arranged at intervals with the inner wall of the fluid channel in the second position, and the first sealing element surrounds the valve core and is arranged at intervals with the valve core. By adopting the technical scheme, the valve body is connected with the valve seat to form the fluid channel, the valve core comprises the vent and is communicated with the fluid channel, so that when the valve core is at the first position, the valve core is contacted with the inner wall of the fluid channel, the vent is communicated with the fluid channel, so that external fluid can flow in the fluid channel, meanwhile, the first sealing piece seals the gap between the valve core and the inner wall of the fluid channel, the fluid is prevented from flowing in or out from the gap between the valve core and the inner wall of the fluid channel, and the sealing effect is ensured. Meanwhile, the first sealing piece surrounds the valve core and is located between the valve body and the valve seat, so that the first sealing piece can be stabilized, and the sealing failure caused by falling of the first sealing piece is prevented from affecting the flow track of fluid. At the second position, the valve core and the inner wall of the fluid channel are arranged at intervals, the first sealing piece surrounds the valve core and is arranged at intervals with the valve core, at the moment, the fluid channel is opened and is in a maximum fluid circulation state because the fluid channel is not blocked by the valve core, the inflow or outflow of fluid is facilitated, and the rapid inflow and outflow of the fluid can be realized. In the process of switching the valve core from the first position to the second position, a user can rotate the valve core to change the size of the passage opening of the fluid passage, so that the speed of inflation and deflation is adjusted. According to another specific embodiment of the utility model, the air valve is disclosed in an embodiment of the utility model, at least one rib is arranged on one side, facing the valve core, of the first sealing element, and the at least one rib is arranged at intervals along the circumferential direction, wherein in the first position, the at least one rib is abutted against the valve core, and in the second position, the at least one rib surro
