[0027] In actual application of this embodiment, when the hierarchical shock absorbing mechanism is used, during the operation of the air compressor, when the driving motor 105 generates vibration during the movement of the air compressor, since the outer bracket 201 and the inner bracket 203 are spaced apart, and the piston chamber 301 is assembled in the outer card slot 202, the airbag 302 is filled with inert gas, and the bottom of the airbag 302 is elastically connected to the inner card slot 204, so that the inner bracket 203 is elastically connected to the outer bracket 201 through the airbag 302 filled with gas in the circumference, and the driving motor 105 generates vibration during the movement of the air compressor. The energy of the rotation of the engine 105 can cause it to vibrate in a circumferential direction, and during the vibration process, it can continuously squeeze a plurality of airbags 302 during irregular vibration. When the airbags 302 are squeezed and elastically deformed, the piston 306 on one side of the guide cavity 303 can discharge the fluid therein toward the drain pipe 305 at one end under the gas pressure, and when the pressure on one side of the airbag 302 disappears, the piston 306 in the guide cavity 303 can be elastically reset, and at the same time, the airbag 302 can be elastically restored, so that the guide cavity 303 is 03 is in a negative pressure state, and the coolant can be sucked from the liquid inlet pipe 304, so that the airbag 302 can continuously perform a suction action under pressure, and the coolant can flow continuously between the plurality of pump flow components 3, and the outflowing coolant can be guided to the screw cavity 103 through the liquid inlet branch pipe 406. After the coolant passes through the rotating sealing ring 401 and flows into the guide pipe 402, it can flow along the guide pipe 403 to the side of the jet port 404 for discharge, and fully contact with the inner wall of the screw cavity 103, and in the contact process The heat generated by friction on the screw 102 can be fully absorbed, and after absorbing the heat, it can flow along the inner wall of the screw cavity 103 to one end of the reflux guide pipe 405, and flow along the reflux guide pipe 405 through the rotating sealing ring 401 and enter the return liquid branch pipe 407. The return liquid branch pipe 407 is connected with the several pump flow components 3, so that the vibration of the air compressor can continuously perform work to circulate the coolant, so that it can have a shock absorbing function and can also fully dissipate the heat of the screw inside the air compressor, which has the effect of energy saving and environmental protection.

[0028] In one case of this embodiment, the coolant medium may be a medium with a lower viscosity such as cooling water or cooling oil, which is not specifically limited here.

[0029] See also Figure 2 In a preferred embodiment of the present invention, the frame member 2 further includes an elastic member 205 , which is fixedly arranged at both side ends of the inner bracket 203 and elastically and slidably connected to the outer bracket 201 .

[0030] In actual application of this embodiment, the elastic member 205 is arranged on the sides of the outer bracket 201 and the inner bracket 203, and elastically connects the outer bracket 201 and the inner bracket 203, which can reduce a small amount of vibration of the air compressor in the direction of the motor shaft and prevent the outer bracket 201 and the inner bracket 203 from vibrating away.

[0031] See also Figure 3 In a preferred embodiment of the present invention, the pump flow component 3 also includes a first magnetic component 307 and a second magnetic component 308, the first magnetic component 307 is fixedly arranged at one end of the piston component 306, the second magnetic component 308 is fixedly assembled on the airbag 302 and arranged close to the inner bracket 203, and the polarities of the first magnetic component 307 and the second magnetic component 308 are matched.

[0032] In actual application of this embodiment, the first magnetic component 307 is arranged at one end of the piston component 306, and the second magnetic component 308 is arranged at one end of the inner bracket 203. When the outer slot 202 is pressed toward the side of the outer bracket 201 under the action of vibration, the second magnetic component 308 can be made to approach the side of the first magnetic component 307, and the piston component 306 can be driven to slide toward the inside of the guide cavity 303 under the action of magnetic force, so that the coolant medium inside the guide cavity 303 is discharged toward one end of the drain pipe 305. When the second magnetic component 308 moves toward the side away from the first magnetic component 307, the piston component 306 can be reset under the elastic force, and the coolant can be sucked through the inlet pipe 304 under the action of negative pressure, so that the coolant between several connected pump flow components 3 can flow continuously.

[0033] See also Figure 3 In a preferred embodiment of the present embodiment, the pump flow component 3 also includes a one-way valve core 309, which is arranged in the liquid inlet pipe 304 and the liquid discharge pipe 305, and is used to limit the flow direction of the coolant in the guide cavity 303, the liquid inlet pipe 304 and the liquid discharge pipe 305.

[0034] In actual application of this embodiment, the one-way valve core 309 is arranged in the liquid inlet pipe 304 and the liquid discharge pipe 305, which can limit the flow direction of the coolant medium in the liquid inlet pipe 304 and the liquid discharge pipe 305, so as to realize the one-way flow of the coolant therebetween, prevent the coolant medium from being diverted in the liquid inlet pipe 304 and the liquid discharge pipe 305, and at the same time, cooperate with the reciprocating motion of the piston member 306 to realize the automatic suction action of the coolant medium.

[0035] In one case of the present embodiment, the single-sided airbag 302 can pump the coolant therein to flow when under pressure, and since several pump flow components 3 are unidirectionally connected through the liquid inlet pipe 304 and the liquid discharge pipe 305, the coolant medium can circulate simultaneously when one side is under pressure.

[0036] See also Figure 4 In a preferred embodiment of the present invention, the jet port 404 is arranged close to the driving motor 105 , and the reflux guide pipe 405 is arranged away from the driving motor 105 .

[0037] In actual application of this embodiment, when the coolant medium flows to the side of the jet outlet 404 through the guide pipe 403, it can flow from the end close to the drive motor 105 to the end away from the drive motor 105, thereby evenly absorbing heat from the inner wall of the screw cavity 103, thereby achieving overall heat dissipation of the screw 102, and the coolant after absorbing heat can flow along the inner wall of the screw cavity 103 to one end of the reflux pipe 405, and be discharged to the return liquid branch pipe 407 through the reflux pipe 405, and the coolant in the return liquid branch pipe 407 can circulate to the liquid inlet pipe 304 again, and flow unidirectionally between several pump flow components 3, thereby achieving the circulation of the coolant medium.

[0038] See also Figure 5 In a preferred embodiment of the present invention, the single-screw air compressor with a layered shock-absorbing mechanism also includes a duct assembly 5, and the duct assembly 5 includes a connecting hose 501. The connecting hose 501 is arranged between a plurality of air bags 302, and is respectively connected to the liquid inlet pipe 304 and the liquid discharge pipe 305 on two adjacent air bags 302, so as to guide the flow of the coolant.

[0039] In actual application of this embodiment, the connecting hose 501 is connected between several adjacent liquid inlet pipes 304 and liquid discharge pipes 305, so that the coolant can flow unidirectionally between several pump flow components 3, thereby achieving heat conduction and heat dissipation of the coolant during its flow process, and achieving natural heat dissipation with the help of external air flow.

[0040] In one case of the present embodiment, the duct assembly 5 also includes a connecting hard tube 502 and heat dissipation fins 503, wherein the connecting hard tube 502 is arranged on the connecting soft tube 501, and the heat dissipation fin 503 array is assembled on the connecting hard tube 502. Since the inner bracket 203 vibrates irregularly in the outer bracket 201, when the outer bracket 201 and the inner bracket 203 are close to each other, the air between the outer bracket 201 and the inner bracket 203 can be squeezed, and during the resetting process of the inner bracket 203, the reciprocating flow of air is realized, so that the gas can continuously contact the surface of the heat dissipation fin 503 during the flow process and absorb the heat thereon, thereby realizing heat conduction of the coolant in the connecting hard tube 502.

[0041] The above-mentioned embodiment of the present invention provides a single-screw air compressor with a hierarchical shock-absorbing mechanism, and through an inner bracket 203 movably arranged in an outer bracket 201, and a plurality of pump flow components 3 arranged between the outer bracket 201 and the inner bracket 203, it can absorb the energy of vibration to perform work when the air compressor vibrates during operation, and can continuously pump the coolant to guide and dissipate heat for the screw inside the air compressor, and cool the coolant in conjunction with the movement of the inner bracket 203, thereby achieving a shock-absorbing effect while effectively dissipating heat for the air compressor.
