[0023] In the above scheme, the first one-way valve 5 is a thin-walled cylindrical structure made of soft rubber material, and a reversible first flap 51 extends inward from its top surface, and a first columnar step 22 extends backward from the central channel 21 of the adapter 2. The first one-way valve 5 is inserted into the first columnar step 22, and the outer side surface of the first columnar step 22 is deformed and fixed, and the first flap 51 on the top surface covers the central channel 21; when negative pressure is generated at the rear of the first flap 51, the fluid enters the central channel 21 from the front end and pushes the first flap 51 backward to enter the central hole 31 of the mounting seat 3; conversely, when positive pressure is generated at the rear of the first flap 51, the first flap 51 tightly fits and closes the central channel 21.
[0024] In addition, a first annular hole 52 is cut out between the first flap 51 and its side wall to facilitate flipping.
[0025] In the above scheme, the second one-way valve 6 is a thin-walled cylindrical structure made of soft rubber material, with a reversible second flap 61 extending inward from the middle, and a second columnar step 34 extending outward from the exhaust channel 32 of the mounting seat 3. The second one-way valve 6 is inserted into the second columnar step 34, and the outer side surface is deformed and fixed, and the second flap 61 thereon covers the exhaust channel 32; when negative pressure is generated inside the second flap 61, the second flap 61 is tightly attached to close the exhaust channel 32, and when positive pressure is generated inside the second flap 61, the second flap 61 is pushed outward to exhaust air outward through the exhaust channel 32.
[0026] In addition, a second annular hole 62 is cut out between the second flap 61 and its side wall to facilitate flipping.
[0027] The second one-way valve 6 is an integrated cylindrical structure with an open top. When in use, the wind coming out of the exhaust passage 32 has no resistance, and thus no noise caused by wind resistance is generated.
