Abstract
The utility model discloses a compressor internal admission automatic cooling structure which comprises a casing body and a motor component arranged in the casing body. The casing body is provided with an air inlet and an air outlet. The compressor internal admission automatic cooling structure is characterized in that a motor chamber is provided with an air inlet hole corresponding to the air inlet of the casing body; a piston is arranged in the air outlet of the casing body; and the piston is provided with an airflow channel from which air in the casing body is discharged. The compressor internal admission automatic cooling structure gets rid off auxiliary parts such as a fan, reduces power and noise and has excellent popularization value, and internal admission automatic cooling is realized.
Description
Technical field
The utility model relates to the Compressor Technology field, specifically a kind of automatic cooling structure of interior air inlet of compressor.
Background technique
Tradition is applied to the oilless compressor cooling means to be had: dispel the heat by increasing supplementary equipment such as surperficial efficiently radiates heat area and increase fan in shape, this method increases the loss of merit, increases noise.As patent No. CN200820300200.9, denomination of invention is the non-lubricated compressor interstage cooler, it is connected to a vertical air-water separation unit behind the gas cooling unit, this unit is by inner core is housed in urceolus, the outlet pipe that passes urceolus is housed in inner core, be formed with the gas baffling passage between inner/outer tube and the outlet pipe, outside the inner core lower ending opening, be provided with manger board, be provided with the dash rib at outer tube inner wall.The utility model is contained between non-lubricated compressor and the I and II compression cylinder; not only can effectively isolate the moisture in the one-level pressurized gas; the selflubricating environment that forms with the polytetrafluoroethylene material in the protection secondary cylinder; improve the reliability of machine run and the working life of easily damaged parts; but manufacture cost is higher, is unfavorable for promoting.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, power consumption, low noise, and the automatic cooling structure of air inlet in the compressor of effective cooling motor.
The utility model is to adopt following technical solution to realize above-mentioned purpose: the automatic cooling structure of air inlet in a kind of compressor, the electric machine assembly that comprises housing and interior setting thereof, housing is provided with inlet, outlet, it is characterized in that, described motor cavity volume is provided with the inlet hole corresponding with shell air inlet, be provided with piston in the air outlet of housing, piston is provided with the air-flow path that the gas in the housing is discharged.
As further specifying of such scheme, the inlet hole of described air-flow path is arranged on the side of piston, and this inlet hole extends to the turnover of piston centerline and runs through piston along the piston centerline direction.
The edge, air outlet of described housing bends inwards, and with the piston sliding contact.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the motor cavity volume to be provided with the inlet hole corresponding with shell air inlet, be provided with piston in the air outlet of housing, piston is provided with the air-flow path that the gas in the housing is discharged, air-flow at first sucks the interior cooling motor of cavity volume of electric machine assembly, during piston motion, after being inhaled into piston, the gas in the motor cavity volume discharges, effectively cooling motor, no power consumption, low noise.

Embodiment
As shown in Figure 1, the automatic cooling structure of air inlet in a kind of compressor of the utility model, the electric machine assembly 2 that comprises housing 1 and interior setting thereof, housing 1 is provided with inlet, outlet 3,4, the motor cavity volume is provided with the inlet hole corresponding with shell air inlet, is provided with piston 5 in the air outlet of housing 1, and piston 5 is provided with the air-flow path 5-1 that the gas in the housing is discharged, the edge, air outlet of housing bends inwards, and with the piston sliding contact.The inlet hole 5-2 of air-flow path is arranged on the side of piston, and this inlet hole extends to the turnover of piston centerline and runs through piston along the piston centerline direction.
In the using process, the airflow direction of control compressor air inlet: air-flow is unidirectional to be entered, and at first enters the cavity volume cooling motor of electric machine assembly, and piston motion gas is sucker once more, and body is discharged in the back.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
