[0061] A control valve 28 is provided at the air intake port recessed in the first connecting seat 251. The control valve 28 can change between a one-way state and an open state. A top abutting convex seat 346 is formed by the downward extension of the peripheral part of a first inner through hole of the valve core plate 341, so that the bottom surface of the valve core plate 341 has the top abutting convex seat 346 and the remaining area. The bottom surface of the valve core plate 341 cooperates with the control valve 28. Whether the control valve 28 is in an open state or a one-way state is determined by whether the top abutting convex seat 346 abuts and compresses the control valve 28. When the reversing valve core group 34 is in the exhaust position, the top abutting convex seat 346 abuts and compresses the control valve 28 to make the control valve 28 in an open state, and the gas in the air chamber is exhausted outward through the control valve, the first inner through hole, etc. When in the first and second air intake positions, the remaining area cooperates with the control valve 28 to make the control valve 28 in a one-way state (one-way valve). When in the second air intake position, the outside air enters the air intake port through the second inner through hole and unidirectionally opens the control valve to pump air into the second air connection path. The control valve 28 includes a plug that can be connected to move up and down in the air intake port and a third elastic body provided in the air intake port. The third elastic body abuts the plug from the inside to the outside. The plug can move between an open position and a closed position relative to the air intake port. The plug abuts and cooperates with the bottom surface of the valve core plate. When the top abutting convex seat 346 cooperates with the control valve, the top abutting convex seat can abut the plug to make it in an open position. When the remaining area cooperates with the control valve 28 and is in the second air intake position, the outside air drives the plug to slide downward to the open position through the first inner through hole so that the outside air pumps air into the second air connection path through the control valve. When there is no outside air or the outside air pressure is small, the control valve is in a closed position. Through the above structure, it can be ensured that the control valve is in an open state during the exhaust state and in a one-way valve state in other states (including the air pumping state), improving the air pumping and exhaust performance.

[0062] A second elastic body 345 is provided between the air separation plate 342 and the middle section 27. The second elastic body 345 sleeved on the air separation plate 342 abuts against the bottom of the inner cavity of the middle section 27 and the flange protruding on the air separation plate 342. First, it can make the valve core plate seal and abut against the sealing plate, enhancing the sealing performance. Second, when rotating the operating member, the reversing valve core group can move downward by pressing the operating member to reduce the friction between the valve core plate and the sealing plate. Third, it can increase the operating feel.

[0064] In another specific embodiment: The difference from the previous specific embodiment is that a control valve 28 is provided at the air intake port recessed in the first connecting seat 251. The control valve 28 can change between a one-way state and an open state. Peripheral portions of the two first inner through holes of the valve core plate 341 extend downward to form abutting convex seats 346, so that the bottom surface of the valve core plate 341 has two abutting convex seats 346 and the remaining regions. The bottom surface of the valve core plate 341 cooperates with the control valve 28 to make the control valve 28 in an open state or a one-way state by whether the abutting convex seats 346 abut and compress the control valve 28. When the commutation valve core group 34 is in the exhaust position and the second air intake position, the abutting convex seats 346 abut and compress the control valve 28 to make the control valve 28 in an open state. When in the first air intake position, the remaining regions cooperate with the control valve 28 to make the control valve 28 in a one-way state (one-way valve).
