Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-3In this embodiment of the present invention, a high-efficiency inflation device includes a base 1, on which an air intake 2 and an inflation cylinder 16 are fixedly connected. A first limiting ring 3 is fixedly connected to the bottom of the inner wall of the air intake 2, and a first air inlet box 5 is provided at the bottom of the first limiting ring 3. A second limiting ring 4 is fixedly connected to the top of the inner wall of the air intake 2, and a second air inlet box 6 is provided at the top of the second limiting ring 4. A sliding air plug 7 is slidably connected between the first limiting ring 3 and the second limiting ring 4 and is located inside the air intake 2. A sealing ring 8 is provided between the air intake cylinder 2 and the air intake cylinder 2. A first air intake port 12 is provided in the first air intake box 5, and a second air intake port 14 is provided in the second air intake box 6. A first one-way valve 13 is installed in the first air intake port 12, and a second one-way valve 15 is installed in the second air intake port 14. A fixed cylinder 9 is fixedly connected to the top of the air intake cylinder 2. A connecting rod 10 is slidably connected in the fixed cylinder 9. One end of the connecting rod 10 is fixedly connected to the sliding air plug 7, and the other end of the connecting rod 10 is fixedly connected to the handle 11.

[0018] The air cylinder 16 has two sets of symmetrically arranged partitions 17 fixedly connected inside. A first air chamber 18 is located at the top of each partition 17, and a second air chamber 19 is located at the bottom of each partition 17. A third air chamber 21 is located between the two sets of partitions 17. A third one-way valve 22 and a fourth one-way valve 23 are installed within each set of partitions 17, and the third one-way valve 22 and the fourth one-way valve 23 are symmetrically arranged. A first connector 24 is installed within the third air chamber 21, and the first connector 24 is connected to the third air chamber 21. An air nozzle is connected to a connector 24. An air guide pipe 20 is connected between the second air intake box 6 and the second air chamber 19. The air guide pipe 20 connects the second air intake box 6 and the second air chamber 19. A second connector 25 is installed in the first air chamber 18 and is connected to the first air chamber 18. A third connector 26 is installed in the first air intake box 5 and is connected to the first air intake box 5. A connecting hose 27 is connected between the third connector 26 and the second connector 25.

[0019] This utility model first connects the air nozzle to the valve. Then, the operator can hold the handle 11 with both hands and pull the handle 11 back and forth. The handle 11 drives the connecting rod 10 to move back and forth in the air pump 2. When the connecting rod 10 drives the sliding air plug 7 to rise, the air pressure in the first air box 5 increases and the air pressure in the second air box 6 decreases. At this time, the first one-way valve 13 opens and the second one-way valve 15 closes. At this time, the external gas enters the second air box 6 along the second air inlet 14, while the gas in the first air box 5 enters the first air chamber 18 along the connecting hose 27. The gas pressure in the first air chamber 18 increases. At this time, the third one-way valve 22 opens and the fourth one-way valve 23 closes. The gas in the first air chamber 18 enters the third air chamber 21 along the third one-way valve 22 and finally enters the air nozzle along the first connector 24.

[0020] Then, when the connecting rod 10 drives the sliding air plug 7 to descend, the air pressure in the first air intake box 5 decreases and the air pressure in the second air intake box 6 increases. At this time, the first one-way valve 13 closes and the second one-way valve 15 opens. At this time, the external gas enters the first air intake box 5 along the first air intake port 12, while the gas in the second air intake box 6 enters the second air chamber 19 along the air guide pipe 20. The gas pressure in the second air chamber 19 increases. At this time, the third one-way valve 22 closes and the fourth one-way valve 23 opens. The gas in the second air chamber 19 enters the third air chamber 21 along the fourth one-way valve 23, and finally enters the air nozzle along the first connector 24.

[0021] This allows for two sets of inflation in a single pass, improving the inflation efficiency of the equipment.

[0022] In one instance of this embodiment, please refer to Figures 1-3 The air intake 2 is fixedly connected to two sides by a fixed shaft 28, and a pedal 29 is rotatably connected to the fixed shaft 28. The present invention uses the fixed shaft 28 to rotate and install the pedal 29 so as to fold and retract the pedal 29 and to fix the equipment by stepping on it.
