[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example

[0028] Please combine Figure 2-4 , a mistake-proof and convenient double-reed air supply valve of the present embodiment includes a valve seat 1 and a valve core 6. The outer periphery of the valve core 6 is covered with a circle of valve core 6 rubber bag 2. The edge of the valve seat 1 is stretched outward to form a cavity for accommodating the valve core 6. The valve core 6 is embedded in the cavity of the valve seat 1 and forms an interference fit with the valve seat 1 through the valve core 6 rubber bag 2. The overall arrangement of the equipment is convenient for customers to install, and the problem that the customer's valve core 6 is easy to install in the wrong direction, resulting in failure of the air supply valve, is solved, and the problem that the rubber ring is easily pulled, deformed and damaged during installation and disassembly is eliminated. At the same time, the sealing performance of the air supply valve is improved, so that the flow characteristics of the air supply valve are more stable and the air supply effect is better.

[0029] The valve seat 1 is nested with the valve core 6 and provides the valve core 6 with a rubber bag 2 to achieve a close fit, making the installation of the valve core 6 more convenient and stable. The valve core 6 is embedded in the valve seat 1 to set the top positioning error-proofing glue and the positioning groove and positioning hole, which have positioning ridges, reduce the errors made by the user during installation, and bring convenience to the staff.
