Further, it is close to filter the piece the one end of closing cap is provided with welds the net circle, it blocks the piece to be provided with on the outer lane of net circle to weld, be provided with the round hole on the closing cap, the diameter of round hole is less than weld the diameter of net circle, weld the net circle with be provided with the filtration circle between the closing cap.

Further, the filtering piece is a cylindrical filtering sponge, and the filtering ring is a circular filtering sponge.

Further, the shell is a circular net cylinder.

The utility model has the advantages that: the utility model discloses the structure has adopted including shell and filtration piece, the one end of shell is provided with out the gas cap, and the other end is provided with the closing cap, it establishes to filter the piece cover on the shell and with go out the gas cap with the closing cap cooperatees, and during the use, the air is filtered the piece and is gone into the cavity in the shell, flows from the gas outlet that goes out on the gas cap again. The following advantages are obtained in comparison with the closest prior art: the whole structure is simple and compact, and the use is convenient; the filtering piece is directly sleeved on the shell, so that the assembly and disassembly are convenient, and the maintenance is facilitated; structural design is reasonable, and it easily solves to filter the piece damage problem, and the filter effect is good, and economic benefits is high.

Detailed Description

As shown in fig. 1 to 3, the present invention specifically comprises: the utility model discloses it includes shell 1 and filtering piece 2, the one end of shell 1 is provided with out gas cap 3, and the other end is provided with closing cap 4, filter 2 covers and establish on the shell 1 and with go out gas cap 3 with closing cap 4 cooperatees, and during the use, the air is filtered 2 back entering shell 1 interior cavity of filtration of piece, flows from the gas outlet that goes out on the gas cap 3 again. Shell 1 can ventilate and breathe freely, the circulation that does not obstruct the air, filter 2 covers on shell 1, go out the mutual adaptation of air outlet cover 3 and closing cap 4 and shell 1, can play the restriction effect to filtering piece 2 through going out air outlet cover 3 and closing cap 4, when using, go out the external article that needs clean air of the gas outlet on the air outlet cover 3, the air gets into shell 1's inner chamber all around from filtering piece 2, through filtering action of filtering piece 2, the air that enters into shell 1 inner chamber all is purified air, when needing to be changed and filtering piece 2, only need to take off from shell 1 with filtering piece 2, again with new filter sheathe in can.

In this embodiment, the both ends of shell 1 all encircle and are provided with a plurality of spacing pieces 5, filter piece 2 and a plurality of spacing piece 5 cooperatees, go out gas lid 3 with all be provided with flange 6 on the closing cap 4, flange 6 with filter piece 2 cooperatees. Both ends of shell 1 have all set up spacing piece 5, and its height and filter piece 2 are corresponding, play fine restriction effect to filtering piece 2, go out the diameter size and the 5 looks adaptations of spacing pieces of flange 6 of gas cap 3 and closing cap 4 to can cover a small part of filtering piece 2 when the installation, can play restriction and a little guard action.

In this embodiment, one end of the filter element 2 close to the sealing cover 4 is provided with a welding mesh ring 7, an outer ring of the welding mesh ring 7 is provided with a blocking sheet 8, the sealing cover 4 is provided with a circular hole 9, the diameter of the circular hole 9 is smaller than that of the welding mesh ring 7, and a filtering ring 10 is arranged between the welding mesh ring 7 and the sealing cover 4. The diameter of welding net circle 7 and the big or small looks adaptation of shell 1 inner chamber, be provided with the obstruction piece 8 on welding net circle 7's outer lane, the position that welding net circle 7 is absorbed in the inner chamber of shell 1 just is unanimous with the length of obstruction piece 8, round hole 9 on closing cap 4 is also an air inlet, the size of the filtration circle 10 that sets up between welding net circle 7 and closing cap 4 and the diameter looks adaptation of welding net circle 7, obstruction piece 8 and closing cap 4 restriction filtration circle 10 position, make filtration circle 10 can be in reasonable position, guarantee the filter effect, simultaneously, after increasing this department of filtration, whole structure will possess more efficient filtration efficiency.

In the present embodiment, the filter element 2 is a cylindrical filter sponge, and the filter ring 10 is a circular filter sponge. The filtering sponge is adopted as the filtering piece 2, so that the filtering effect can be achieved, the replacement and the maintenance of the filtering piece are facilitated, and the filtering can be easily completed by using elasticity during the disassembly and assembly; the filtering ring 10 is also a filtering sponge, when being installed, the filtering ring 10 is firstly pinched small and is put in through the round hole 9, then the filtering ring is adjusted again by utilizing the elasticity of the filtering ring, and the filtering ring is directly pulled out during the disassembly, which is very convenient.

In this embodiment, the housing 1 is a cylindrical net cylinder. The circular net cylinder has a good ventilation effect, does not obstruct the circulation of air, and has enough strength to bear certain pressure.

While the embodiments of the present invention have been described in terms of practical embodiments, they are not intended to limit the scope of the invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
