Description of the drawings
Fig. 1 is explosive view of the utility model for an embodiment of the filter of filtering compressed air；
Fig. 2,3 are that the utility model is used for the filter upper shell of filtering compressed air and the assembling schematic diagram of lower housing.
Specific embodiment
Below in conjunction with the accompanying drawings, by specific embodiment, the technical solution of the utility model is carried out it is clear, completely retouch
It states.
It please refers to Fig.1 shown in -3, the utility model provides a kind of filter for filtering compressed air, including upper shell
1st, lower housing 2 and filter core 3, the lower housing 2 are snapped connection with the upper shell 1, and the filter core 3 blocks with the upper shell 1
Button is connected and stretched into the lower housing 2.
It can only be installed or removed by human hand using the connection mode snapped connection, special work need not be used
Tool, dismounting is very convenient, so as to replace the efficient of filter core 3, convenient for safeguarding.
The outer wall of the upper shell 1 is equipped with the first convex block 11, and the inner wall of the lower housing 2 is equipped with the second convex block 22, described
Second convex block 22 is clasped with first convex block 11, connects so as to fulfill the buckle of the upper shell 1 and the lower housing 2
It connects.In one embodiment, first convex block 11 is L-shaped, and second convex block 22 is rectangular.As shown in Fig. 2, by the lower housing
2 stretch to the upper shell 1 so that second convex block 22 aligns the snapped-in position of first convex block 11, then rotate described in
Lower housing 2 may be such that the formation of second convex block 22 and first convex block 11 is clasped, as shown in figure 3, thus by institute
It states lower housing 2 and is installed on the upper shell 1.In the present embodiment, it is convex that the upper shell 1 is equipped with several first in its circumferential direction
Block 11, similarly, it is convex that the lower housing 2 is equipped with corresponding with 11 quantity of the first convex block several second in its circumferential direction
Block 22.During installation, first so that the second convex block 22 from the interval of the first adjacent convex block 11 through be rotated further by lower housing 2 can will
The lower housing 2 is installed on the upper shell 1.
The upper shell 1 is equipped with inlet channel 101 and outlet passageway 102, the inlet channel 101 and the outlet passageway
102 separate, and one end of the filter core 3 is installed on the inlet channel 101, described in the connects with the internal cavities of the filter core 3 into
Gas passage 101 and the outlet passageway 102.Compressed air enters filter core 3 from inlet channel 101, from going out after the filtering of filter core 3
Gas passage 102 flows out.
101 inner wall of inlet channel is equipped with the 3rd convex block 13, and 3 outer wall of filter core is equipped with the 4th convex block 34, and described the
Four convex blocks 34 are clasped with the 3rd convex block 13.The structure of 3rd convex block 13 and the 4th convex block 34 can with it is described
