[0041] For further information, please also refer to Figure 2 and Figure 3 The high-pressure air pump of this embodiment also includes a stator assembly 5 and a rotor assembly 4 that can rotate relative to each other. The cylinder assembly 1 includes an upper shell 11 and a main body 15. The stator assembly 5 is fixedly connected to the upper shell 11, and the rotor assembly 4 is arranged in the upper shell 11 and is rotatably connected to the main body 15; an isolation cover 6 is fixedly provided on the main body 15 for separating the stator assembly 5 and the rotor assembly 4, the rotor assembly 4 is arranged on the inner side of the isolation cover 6, and the stator assembly 5 is arranged on the outer side of the isolation cover 6; the air pump of this embodiment also includes a cylinder body 3, and an oil storage bottom cover 32 is provided on the side of the cylinder body 3 away from the isolation cover 6. The oil storage bottom cover 32 and the cylinder body 3 are detachably connected, and a sealing sheet is provided between the oil storage bottom cover 32 and the cylinder body 3. The sealing sheet is configured as a Teflon sheet. Specifically, the thickness of the Teflon sheet is configured to be 0.2 mm. This arrangement has the advantages of reliable sealing, space saving, and simple installation.

[0042] Furthermore, please combine Figure 6, the cylinder body 3 is located below the main body 15, the rotor assembly 4 includes an eccentric shaft 7, and the end of the eccentric shaft 7 away from the upper shell 11 is sleeved with a balance wheel ring 71; a sink groove is provided at the bottom of the cylinder body 3, and the balance wheel ring 71 is rollingly connected to the sink groove. The air pump of this embodiment also includes a stopper 10 and a spring 9, the stopper 10 is arranged in the sink groove, and the stopper 10 and the balance wheel ring 71 divide the sink groove into two parts, I and II, wherein I is an air outlet cavity and II is an air inlet cavity; one end of the spring 9 is fixedly connected to the cylinder body 3, and the other end is fixedly connected to the stopper 10, and the balance wheel ring 71 is movably abutted against the stopper 10, and the balance wheel ring 71 rotates to adjust the position of the stopper 10 relative to the cylinder body 3, thereby adjusting the volume of the air inlet cavity II and the air outlet cavity I. The specific working process is: the rotor assembly 4 rotates, that is, the eccentric shaft 7 rotates, and the eccentric shaft 7 drives the balance wheel ring 71 to rotate clockwise. It can be understood that clockwise here refers to Figure 6 From the perspective, the balance wheel ring 71 rotates or rolls in the sink in the clockwise direction, and the balance wheel ring 71 squeezes the stopper 10, so that the size of the stopper 10 in the sink becomes smaller. At this time, the space of the air inlet chamber II gradually increases, and the gas is sucked in from the air inlet interface 21 of the air inlet component 2, filtered through the filter 22, and enters the cylinder component 1 through the air inlet pipe 23. As the balance wheel ring 71 continues to rotate, the sucked gas enters the air outlet chamber I. During the clockwise rotation of the eccentric shaft 7 and the balance wheel ring 71, the space of the air outlet chamber I gradually decreases, and the gas is subjected to greater pressure and is compressed into high-pressure gas, such as Figure 2 and Figure 7 As shown, a valve plate 16 is provided on the main body 15. The high-pressure gas will push open the valve plate 16 and move upward, and then pass through the oil-gas separation cover 17 provided on the main body 15 to separate the high-pressure gas from the lubricating oil. The high-pressure gas then passes through the gap between the rotor assembly 4 and the isolation cover 6 and is discharged through the gas outlet interface 14.

[0043] Please also read Figures 3 to 5 The cylinder body 3 is provided with a fixing hole 31, and the air intake pipe 23 is inserted into the fixing hole 31; the air intake assembly 2 also includes two limit blocks, namely a first limit block 24 and a second limit block 25. There is a gap between the first limit block 24 and the second limit block 25, and the gap is defined as a limit gap. A limit frame 8 is provided on the cylinder body 3, and the limit frame 8 is detachably connected to the cylinder body 3. The size of the limit frame 8 matches the size of the limit gap. The limit frame 8 is sequentially inserted into the limit gap and the cylinder body 3. In this way, under the clamping action of the limit frame 8 and the limit gap, the air intake assembly 2 is not easy to fall off from the fixing hole 31. During the installation process, the air intake pipe 23 is first inserted into the fixing hole 31, which is a primary clamping, and then the limit frame 8 is inserted into the cylinder body 3 along the limit gap, which is a secondary clamping. Through the two clampings, the connection tightness between the air intake assembly 2 and the cylinder assembly 1 can be effectively enhanced.

[0044] As an optional implementation, the limit block can also be set to one, and a limit groove 26 can be opened on the single limit block. The size of the limit frame 8 matches the size of the limit groove 26, and the limit frame 8 is connected to the cylinder body 3 through the limit groove 26. The principle is similar to the above method and will not be elaborated on.

[0045] It is understandable that a limit groove 26 may be provided on any one of the two limit blocks, and the width dimension of the limit frame 8 is equal to the sum of the width dimension of the limit gap and the width dimension of the limit groove 26; or both limit blocks may have limit grooves 26, and the width dimension of the limit frame 8 is equal to the sum of the width dimension of the limit gap and the width dimensions of the two limit grooves 26. Such an implementation manner also falls within the protection scope of the present utility model, and the specific connection process will not be further elaborated here.

[0046] In order to ensure the sealing between the intake assembly 2 and the cylinder assembly 1, the sealing measures of this embodiment adopt a double O-ring sealing structure. The external O-ring is used to seal the medium in the intake chamber, and the internal O-ring is used to seal the medium in the outlet chamber. Compared with the traditional riveting process, such a sealing structure has a simple structure, is easy to install, and has better sealing.

[0047] In this embodiment, the first limiting block 24 is configured as an external O-ring, which can not only achieve sealing but also engage with the limiting frame 8 to further enhance the tightness of the connection between the intake assembly 2 and the cylinder assembly 1 .

[0048] In summary, the utility model provides a detachable high-pressure air pump, including an air intake component 2 and a cylinder component 1, the air intake component 2 is used to inhale and filter gas, the cylinder component 1 is used to compress and exhaust gas, the air intake component 2 is detachably connected to the cylinder component 1, the air intake component 2 includes an air intake pipe 23, the cylinder component 1 includes a cylinder body 3, the cylinder body 3 is provided with a fixing hole 31, the air intake pipe 23 is plugged into the fixing hole 31, so that during the cleaning or maintenance of the air intake component 2, it can be removed from the cylinder assembly, which is convenient for cleaning or maintenance operations; on the other hand, the cylinder assembly 1 and the air intake component 2 can be mass-produced separately, and then installed according to the required quantity, which is convenient for mass production and sales, and improves processing efficiency.
