Description

Technical Field

[0001] The utility model relates to the field of machinery, and specifically to an inflatable air nozzle valve that is more convenient to inflate. More specifically, the application provides an inflatable valve that is suitable for a two-stage inflatable pump and can complete inflating at one time. At the same time, the inflatable valve is compatible with the threaded port of an old inflatable base, and the old inflatable boat valve can be unscrewed and directly replaced with the inflatable valve to upgrade the old boat. The inflatable valve has a high application value. Background Art

[0002] As an airtight product, an inflatable boat needs to realize the inflation and deflation functions through an air nozzle. The air nozzle of an inflatable boat usually consists of a valve seat, an inflation valve threadedly connected to the valve seat, and a sealing ring arranged between the valve seat and the valve. Among them, the valve seat is usually fixed on the hull of the inflatable boat, and the inflation valve and the valve seat are threadedly connected. At the same time, in order to improve the airtightness, the air nozzle of the inflatable boat also includes a valve end cover threadedly connected to the working end of the inflation valve, and the valve end cover is used to reduce the leakage of the inflatable boat.

[0003] In the existing inflation valve, a plurality of vent holes are arranged at the bottom of the valve body, and a sealing sheet is connected to the valve body, and the sealing sheet covers the vent holes. With this structure, when the valve body is inflated with an air nozzle, the gas applies pressure to the sealing sheet through the vent holes, causing the sealing sheet to open; when the inflation is completed, the external force disappears, and the sealing sheet returns to its initial position, thus achieving the sealing operation of the vent holes. In some cases, after the airtight product is inflated and formed, it is exposed to the air and sunlight, and the temperature of the gas inside it will continue to rise, thereby affecting the sealing performance of the inflation valve.

[0004] How to improve the inflation valve of an inflatable boat has always been a research direction for inflatable boat developers. To this end, the present application provides a novel inflation valve. Utility Model Content

[0005] The invention of the utility model aims to provide an inflation valve with an ingenious design, simple structure and convenient operation. With the novel inflation nozzle valve of the present application, the valve can be opened by simply plugging in the air pipe. On the basis of maintaining compatibility with the existing air nozzle valve seat, the ventilation cross-sectional area is increased to facilitate rapid inflation. With this structure, after inflation is completed, only the air pipe needs to be unplugged, and the inflation valve will automatically close and remain airtight.

[0006] Furthermore, when in use, the trachea is brought into contact with the inflation valve, and the external force provided by the trachea is used to open the inflation valve, and then the corresponding inflation operation is performed; when the inflation is completed, the trachea is separated from the inflation valve, at which time the external force acting on the inflation valve disappears, and the inflation valve returns to its initial state, thereby providing good airtightness. The present application is based on the contact operation of the trachea to realize the opening and closing of the inflation valve, which can effectively avoid the occurrence of accidental touch operations and effectively ensure airtightness. Furthermore, the present application adopts a plum blossom-shaped first rotating part design, which can increase the force area of ​​the finger during rotation, and facilitates the effective contact between the trachea and the inflation valve when inserting the trachea.
