Description

Technical Field

[0001] This utility model relates to the technical field of air compressor pumps for oxygen generators, and in particular to an air compressor pump for oxygen generators with dual flow channels for heat dissipation. Background Technology

[0002] To avoid air pollution from lubricating oil, oxygen concentrators need to use oil-free air compressors to meet their high air quality requirements.

[0003] Since there is no lubricating oil, the piston is prone to wear if it slides against the inner wall of the cylinder liner. Therefore, a piston cup can be installed on the piston of the oilless air compressor, and a sliding seal is achieved by the edge of the piston cup sliding against the inner wall of the cylinder liner.

[0004] Although the piston cup reduces wear on the inner wall of the cylinder liner, the friction between the piston cup and the cylinder liner generates a lot of heat. If the piston cup and the cylinder liner cannot dissipate heat in time, it will accelerate the wear of the piston cup and shorten its service life, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an air compressor pump for oxygen generators with dual-channel heat dissipation, thereby improving the heat dissipation effect of the cylinder liner.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An air compressor pump for an oxygen generator with dual-channel heat dissipation includes: a motor, a connecting seat, a cylinder liner, a piston, a piston cup, and a cover. The connecting seat is disposed at one or both ends of the motor. The cylinder liner is disposed on the connecting seat. The piston is disposed in the cylinder liner. The piston cup is disposed on the piston, with the edge of the piston cup slidingly contacting the inner wall of the cylinder liner. A piston rod extending into the connecting seat is disposed on the back of the piston. The cover is disposed on the opening of the cylinder liner for sealing. An intake air passage extending into the inner wall of the connecting seat is disposed in the inner wall of the cylinder liner. An intake pipe connector communicating with the intake air passage is disposed on the outer side of the connecting seat. An exhaust air passage extending into the inner wall of the connecting seat is disposed in the inner wall of the cylinder liner. An exhaust pipe connector communicating with the exhaust air passage is disposed on the outer side of the connecting seat.

[0008] The connecting seat is provided with a crankshaft that is connected to the rotating shaft of the motor and drives the piston rod to move.

[0009] The cover is provided with a first one-way valve that connects the air intake passage and the cylinder liner.

[0010] The cover is equipped with a second one-way valve that connects the exhaust passage and the cylinder liner.

[0011] The number of exhaust channels is at least one.

[0012] The number of air intake channels is at least one.

[0013] The beneficial effects of this utility model are as follows: An air compressor pump for oxygen generators with dual-channel heat dissipation is specially designed with a dual-channel heat dissipation structure. When the external airflow enters the cylinder liner through the intake channel, it can carry away the heat of the cylinder liner. When the air in the cylinder liner is discharged through the exhaust channel, it can also carry away the heat of the cylinder liner. This enhances the heat dissipation of the cylinder liner and helps to remove the heat from the piston cup, avoiding the problem of accelerated wear of the piston cup due to high temperature. This helps to extend the service life of the piston cup and cylinder liner and reduce the frequency and cost of maintenance. Attached Figure Description

[0017] like Figure 1 The air compressor pump for the oxygen concentrator shown includes: a motor 1, a connecting seat 2, a cylinder liner 5, a piston 4, a piston cup 7, and a cover 6. The connecting seat 2 is located at one or both ends of the motor 1. The connecting seat 2 and the motor 1 housing can be fixed with screws, making disassembly and assembly convenient.

[0018] The cylinder liner 5 is mounted on the connecting seat 2. In this embodiment, the cylinder liner 5 is located on the top of the connecting seat 2 and can be an integrated steel structure with high strength.

[0019] The piston 4 is disposed within the cylinder liner 5, and the piston cup 7 is disposed on the piston 4, moving back and forth within the cylinder liner 5 along with the piston 4. The edge of the piston cup 7 slides in contact with the inner wall of the cylinder liner 5, allowing airflow to be drawn in and discharged, ensuring good airtightness.

[0020] A piston rod 3 extending into the connecting seat 2 is provided on the back of the piston 4. In this embodiment, the connecting seat 2 is provided with a crankshaft that is connected to the rotating shaft of the motor 1 and drives the piston rod 3 to move, thereby realizing the reciprocating drive of the piston 4.

An intake pipe connector 10 connected to the intake air passage 8 is provided on the outer side of the connecting seat 2. An external filter is connected to the intake pipe connector 10 to introduce external air into the intake air passage 8. As the air enters the cylinder liner 5 through the intake air passage 8, it can carry away the heat of the cylinder liner 5, thereby realizing the heat dissipation of the diaphragm cup 7.

[0023] The number of intake air passages 8 is at least one, and the number of exhaust air passages 9 is at least one. In order to improve the heat dissipation effect and temperature distribution uniformity of cylinder liner 5, multiple intake air passages 8 and exhaust air passages 9 can be used, which are evenly distributed in the inner wall of cylinder liner 5.

[0024] like Figure 1 As shown, the cover 6 is provided with a first one-way valve connecting the intake air passage 8 and the top of the inner cavity of the cylinder liner 5, and the cover 6 is provided with a second one-way valve connecting the exhaust air passage 9 and the top of the inner cavity of the cylinder liner 5.
