Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Referring to fig. 1 to 3, the utility model discloses an air receiver with filtering capability, including air receiver body 1, air outlet department of air receiver body 1 is provided with joint seat 2, has seted up the mounting hole in joint seat 2, is provided with the internal thread in this mounting hole. Connect in the mounting hole to filter and connect 3, filter and connect 3 including the connector 31 and the filter screen skeleton 32 that link to each other, this connector 31 adopts the metal material to process and forms, and filter screen skeleton 32 adopts plastics material to process and forms. A threaded hole is provided in the connection head 31, through which connection with an external pipe can be achieved. The connector 31 is provided with a mounting thread 31c matched with the mounting hole in the connector base 2 and a connecting part 31d connected with the filter screen framework 32. The filter adapter 3 is screwed into the adapter base 2 by the engagement between the mounting thread 31c and the internal thread of the mounting hole. The connection head 31 is further provided with a mounting table 31a and a sealing groove 31b, and an O-ring is disposed in the sealing groove 31b, so as to ensure the sealing effect between the filter adapter 3 and the adapter 2. The filter screen framework 32 comprises a plurality of connecting strips 32a and a plurality of reinforcing rings 32b which are integrally formed, the influence of the filter joint 3 on the air flow rate in the air storage cylinder can be reduced through the framework structure formed by the connecting strips 32a and the reinforcing rings 32b, and the strength of the connecting strips 32a can be improved through the reinforcing rings 32b, so that the strength of the filter screen framework 32 is improved. The filter screen 4 is arranged on the filter screen framework 32, and the filter screen 4 is distributed on the circumferential surface and the end surface of the filter screen framework 32, so that the impurities in the air storage cylinder can be effectively prevented from leaking to an external pipeline through the air outlet.

The diameter of the connecting portion 31d is smaller than the diameter of the mounting screw 31c, and the movement of the screen frame 32 toward the mounting screw 31c can be prevented by the stepped surface between the connecting portion 31d and the mounting screw 31 c.
