Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1 to 6, the utility model provides a high-low pressure dual-purpose air pump, which comprises a frame 1, a driving device 5 connected to the frame 1, a transmission device 2 connected to an output end of the driving device 5, and a first inflation assembly 3 and a second inflation assembly 4 which are arranged on the frame 1 up and down, wherein the first inflation assembly 3 comprises a first cylinder 31, a first piston 32 movably arranged in the first cylinder 31, a first piston ring 33 sleeved on the first piston 32 and tightly connected to an inner side wall of the first cylinder 31, and a first transmission rod 34 connected to the transmission device 2 and the first piston 32; the second inflation assembly 4 comprises a second cylinder 41, a second piston 42 movably arranged in the second cylinder 41, a second piston ring 43 sleeved on the second piston 42 and tightly connected with the inner side wall of the second cylinder 41, and a second transmission rod 44 connected with the transmission device 2 and the second piston 42; the second piston ring 43 and the second transmission rod 44 are obliquely arranged; the piston ring I33 and the transmission rod II 44 are arranged obliquely.
Specifically, the first inflation assembly 3 further comprises a first air inlet 35 arranged on the first piston 32; the second inflation assembly 4 further comprises a second air inlet 45 arranged on the second piston 42; the piston ring I33 and the piston ring II 43 are arranged in a staggered mode in the vertical direction; the driving device 5 can adopt a motor; one-way air outlet valves are arranged at the air outlets of the first cylinder body 31 and the second cylinder body 41. And the first air inlet 35 and the second air inlet 45 are both provided with one-way air inlet valves.
In the actual use process, when the inflation assembly II 4 needs to be used for inflation, the driving device 5 is started and rotates forwards, the driving device 5 drives the first transmission rod 34 and the second transmission rod 44 to move synchronously through the transmission device 2, and the first transmission rod 34 and the second transmission rod 44 respectively convert the rotation of the transmission device 2 into the linear motion of the first piston 32 and the second piston 42; the first piston 32 and the first piston ring 33 are driven by the first transmission rod 34 to slide and swing back and forth in the first cylinder 31, and the second transmission rod 44 drives the second piston 42 and the second piston ring 43 to slide and swing back and forth in the second cylinder 41. As shown in fig. 5, the driving device 5 rotates forward and drives the driven wheel 23 to rotate in the direction a, the second transmission rod 44 drives the second piston 42 to move from the top dead center to the bottom dead center of the transmission device 2, the second transmission rod 44 drives the second piston 42 to move in the direction of moving out of the second cylinder 41, the second piston ring 43 and the second piston 42 swing downward along with the movement of the second transmission rod 44, because the second piston ring 43 and the second transmission rod 44 are obliquely arranged, the angle of swinging downward of the second piston ring 43 on the left side to the right side is larger than the angle of swinging downward of the second piston ring 43 on the right side, so that a gap is formed between the second piston ring 43 on the left side and the inner side wall of the second cylinder 41, and air can flow into the second cylinder 41 from the second air inlet 45 and the gap between the second cylinder 41 and the second piston ring 43. As shown in fig. 6, when the second transmission rod 44 drives the second piston 42 to move to the bottom dead center, the second transmission rod 44 drives the second piston ring 43 on the left side to swing to fit with the inner sidewall of the second cylinder 41 to close the air inside the second cylinder 41, the second transmission rod 44 continues to drive the second piston 42 to move in the direction close to the top dead center, that is, the second transmission rod 44 drives the second piston 42 to move in the direction moving into the second cylinder 41, at this time, the one-way intake valve disposed on the second intake port 45 closes the second intake port 45, the second piston ring 43 and the second piston 42 swing upward along with the movement of the second transmission rod 44, and at the same time, the second piston ring 43 on the left side swings to fit tightly with the inner sidewall of the second cylinder 41, the gas inside the second cylinder 41 is compressed, the high-pressure gas inside the second cylinder 41 causes the second piston ring 43 to expand (for example, elastic deformation occurs), and the connection between the second piston ring 43 and the inner sidewall of the second cylinder 41 is tighter, when the gas pressure in the second cylinder 41 is greater than the valve resistance of the one-way gas outlet valve of the second cylinder 41, the second cylinder 41 starts to exhaust, and when the second piston 42 moves to the top dead center, the exhaust is finished. Similarly, since the piston ring two 43 and the piston ring one 33 are disposed in a staggered and crossed manner, and the swinging directions of the piston ring two 43 and the piston ring one 33 are the same, when the transmission rod one 34 drives the piston ring one 33 to move from the top dead center to the bottom dead center of the transmission device 2, the piston ring one 33 swings downward but no gap or a very small gap is generated between the piston ring one 33 and the inner side wall of the cylinder body one 31, so that the air entering the cylinder body one 31 is correspondingly reduced, and when the piston ring one 33 moves from the bottom dead center to the top dead center, because the air entering the cylinder body one 31 is small, the work of the piston ring one 32 and the piston ring one 33 for compressing the air is correspondingly reduced, and the air discharged from the exhaust port of the cylinder body one 31 is also correspondingly reduced. Similarly, when inflation through the inflation assembly one 3 is required, the driving device 5 is reversed, air entering the cylinder two 41 is reduced, air entering the cylinder one 31 is increased, and then inflation through the inflation assembly one 3 is achieved. The pressure and the flow of the first inflation assembly 3 during inflation are adjusted by adjusting the volume of the first cylinder body 31, the size and the number of the first air inlets 35, the valve pressure resistance of the one-way air outlet valve of the first cylinder body 31 and the like, the pressure and the flow of the second inflation assembly 4 during inflation are adjusted by adjusting the volume of the second cylinder body 41, the size and the number of the second air inlets 45, the valve pressure resistance of the one-way air outlet valve of the second cylinder body 41 and the like, the first inflation assembly 3 can be adjusted to be a high-pressure low-flow inflation assembly according to actual conditions, and the second inflation assembly 4 can be adjusted to be a low-pressure high-flow inflation assembly.

The driving device 5 drives the first transmission rod 34 and the second transmission rod 44 to move synchronously through the transmission device 2, the first piston ring 33 and the second piston ring 43 are crossed in a staggered mode, when high-pressure low-flow inflatable appliances such as tires need to be inflated, the driving device 5 rotates reversely, gas entering the cylinder body II 41 is reduced, gas extruded out of the gas outlet of the second inflatable assembly 4 by the piston II 42 and the piston ring II 43 is correspondingly reduced, and similarly, when low-pressure high-flow inflatable appliances such as inflatable yachts need to be inflated, the driving device 5 rotates forwards, and gas discharged out of the gas outlet of the first inflatable assembly 3 is correspondingly reduced. The piston ring I33 and the piston ring II 43 are staggered and crossed, so that the mutual interference of the work of the inflation assembly I3 and the work of the inflation assembly II 4 can be avoided, and the inflation efficiency of the utility model is improved. The driving device 5 can respectively or simultaneously provide power sources for the first inflation assembly 3 and the second inflation assembly 4, so that the production cost is saved.
