Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As Figures 1-6 Indicated, an air conditioner oil pump with filter screen structure, including pump body 1, the pump body 1 is based on the limit card slot 101 arranged on the outer surface and is divided into disc mechanism 102 and columnar mechanism 103, the columnar mechanism 103 is arranged on the upper surface of the disc mechanism 102, the oil delivery channel 131 is opened in the columnar mechanism 103, the oil delivery channel 131 is through the outer rotor 4 and the inner rotor 5 in the disc mechanism 102, thereby with the oil outlet 123 at the bottom of the disc mechanism 102 is communicated;It also includes filter screen 2 and elastic baffle ring 3, the filter screen 2 is based on the elastic baffle ring 3 and is installed on the outer surface of the columnar mechanism 103.

[0026] In the embodiment, the filter screen 2 is used to filter the impurities in the external lubricating oil, and the elastic retainer 3 is used to fix the filter screen 2 on the outer surface of the columnar mechanism 103. Specifically, when the outer rotor 4 is engaged with the inner rotor 5 to rotate, a periodically changing closed oil cavity is formed between the adjacent teeth. Due to the volume change of the closed oil cavity, the lubricating oil outside the pump body 1 passes through the filter screen and enters the closed oil cavity through the oil delivery channel 131, and is finally pumped out from the oil outlet 123 at the bottom of the pump body 1.

[0027] In one of the embodiments, the filter screen 2 is provided with a fixing groove 201 at the limiting slot 101, the fixing groove 201 is sleeved on the limiting slot 101, and the elastic retainer 3 is sleeved on the outer wall of the fixing groove 201. The elastic retainer 3 is used to fix the filter screen 2 on the limiting slot 101.

[0028] In the embodiment, the inner diameter of the elastic retainer 3 is smaller than the outer diameter of the limiting slot 101 and the outer diameter of the fixing groove 201, so that the filter screen 2 is fixedly sleeved on the outer surface of the columnar mechanism 103.

[0029] In one of the embodiments, the installation slot 121 is formed in the inner bottom of the disc mechanism 102, the oil outlet 123 is arranged at the bottom of the installation slot 121, the disc mechanism 102 at the top of the installation slot 121 is provided with an oil inlet 122, and the oil inlet 122 is connected with the oil delivery channel 131.

[0030] In the embodiment, based on the engagement and rotation of the outer rotor 4 and the inner rotor 5, the external lubricating oil is delivered through the oil delivery channel 131, enters the closed oil cavity formed by the engagement of the outer rotor 4 and the inner rotor 5 in the installation slot 121 through the oil inlet 122, and is finally delivered as lubricating oil from the oil outlet 123.

[0031] In one of the embodiments, the outer rotor 4 is sleeved on the inner wall of the installation slot 121, and the inner rotor 5 is sleeved on the inner wall of the outer rotor 4. The disc mechanism 102 at the top of the installation slot 121 is further provided with an unloading groove 124, the unloading groove 124 and the oil inlet 122 penetrate through the outer rotor 4 and the inner rotor 5, and are in communication with the oil outlet 123.

[0032] In the embodiment, the unloading groove 124 is used to reduce the impact of the engagement and rotation of the outer rotor 4 and the inner rotor 5 on the pump body 1. When the volume of the closed oil cavity decreases, part of the lubricating oil is collected in the unloading groove 124. When the volume of the closed oil cavity increases, the lubricating oil collected in the unloading groove 124 enters the closed oil cavity for delivery.

[0033] In one of the embodiments, the inner wall of the installation groove 121 near the oil outlet 123 end is also provided with a positioning hole 125 and a foolproof hole 126, the bottom of the installation groove 121 is clamped and installed with the sealing sheet 6 based on the positioning hole 125, and the foolproof hole 126 is used for assisting in installing the sealing sheet 6.

[0034] In the embodiment, the sealing sheet 6 is used for preventing the lubricating oil in the pump body 1 from leaking out, and ensuring that the lubricating oil is only discharged from the oil outlet 123 for delivery.

[0035] In one of the embodiments, the bottom of the disc-shaped mechanism 102 is also provided with a plurality of fastening holes 127 for assisting in installing the pump body 1.

[0036] In the embodiment, the fastening hole 127 is used for fixing and installing the oil pump on the air conditioner compressor.

[0037] In one of the embodiments, the outer surface of the columnar mechanism 103 is provided with a plurality of supporting ribs 132, and the outer surface of the supporting rib 132 abuts against the inner surface of the filter screen 2.

[0038] In the embodiment, the supporting rib 132 is used for supporting the filter screen 2, avoiding that the filter screen 2 is adsorbed and tightly attached to the outer surface of the pump body 1 when the outer rotor 4 and the inner rotor 5 are in meshing rotary motion, so as to reduce the oil inlet amount.

[0039] In one of the embodiments, the supporting ribs 132 are formed with oil collecting grooves 133 therebetween, and the top of the columnar mechanism 103 is also provided with a plurality of oil collecting openings 134, and the oil delivery channel 131 is communicated with two adjacent oil collecting grooves 133 based on the oil collecting opening 134.

[0040] In the embodiment, the oil collecting groove 133 and the oil collecting opening 134 are matched, so as to increase the oil amount entering the oil delivery channel 131 and improve the oil supply efficiency.

[0041] The specific implementation of the air conditioner oil pump with the filter screen structure is as follows:

[0042] The filter screen 2 is sleeved on the outer surface of the columnar mechanism 103 and is fixed on the limiting groove 101 based on the elastic check ring 3; when the air conditioner oil pump is installed on the air conditioner compressor and drives the outer rotor 4 and the inner rotor 5 to rotate in engagement, due to the change of the closed oil cavity volume between the outer rotor 4 and the inner rotor 5, the external pressure of the pump body 1 is greater than the internal pressure of the pump body 1, so that the external lubricating oil moves to the closed oil cavity; when the external lubricating oil filters impurities through the filter screen, the lubricating oil can enter the oil conveying channel 131 through the oil collecting groove 133 and the oil collecting opening 134, and can also directly enter from the top of the oil conveying channel 131; the hydraulic oil enters the oil inlet 122 through the oil conveying channel 131, so as to enter the closed oil cavity; based on the change of the closed oil cavity volume, most of the hydraulic oil is conveyed to the air conditioner compressor from the oil outlet 123, and a small part enters the unloading groove 124 and is collected and conveyed again.

[0043] The above describes the utility model and its implementation mode, which is not limited, and the drawings shown are only one of the implementation modes of the utility model, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structure modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
