Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compressors, in particular to a liquid storage device and a compressor. Background Art
[0002] The working principle of the compressor is to use the slider to divide the cylinder into an intake chamber and an exhaust chamber. When the motor is powered on, the stator coil generates an electromagnetic field, and the rotor cuts the magnetic lines to generate power to drive the crankshaft of the pump body to rotate, causing the piston to rotate in the cylinder to compress the refrigerant. Under the action of the crankshaft, the volume of the intake and exhaust chambers is constantly changed, sucking in low-temperature and low-pressure gaseous refrigerant, compressing it into high-temperature and high-pressure gaseous refrigerant and then discharging it from the pump body, and the cycle continues.
[0003] Among them, the liquid reservoir is placed outside the compressor and needs to be fixed by welding, brackets, etc. With the expansion of compressor usage scenarios, the use of dehumidifiers, air conditioners and other products tends to be miniaturized, making the size of compressors and liquid reservoirs smaller and smaller. However, due to the relatively small internal space of the liquid reservoir, the filter inside the liquid reservoir cannot be well fixed by the fixing plate. During operation, the filter fluctuations are prone to generate high-frequency noise. Utility Model Content

[0011] As an implementation manner, the exhaust port is opened on the side wall of one end of the exhaust pipe extending into the interior of the liquid reservoir housing.
[0012] As an implementation manner, the shape of the exhaust port is one of a circle, an ellipse, a square, and a regular polygon.
[0013] As an implementation mode, a plurality of exhaust ports are provided on the side wall of one end of the exhaust pipe extending into the interior of the liquid reservoir housing.
