Description
Technical field
The utility model relates to a kind of air cleaner.
Background technology
Air compressor is quoted widely in daily life, various pneumatic tool all has and relates to, air cleaner on as a rule connecting on air compressor, the dust of outside air etc. can intercept on filter core by air cleaner, guarantees the clean free from admixture of gas that air compressor sprays.Filter core is generally hollow structure, can be provided with filter cloth above, and the gas for the external world passes through, and filter cloth can hinder dust etc. to enter inner chamber, and that guarantees to give vent to anger is pure.
Now because gas is in the process of flowing, in the high velocity jet situation of air-flow mostly, gas shock filter core can produce filter core and necessarily rock, filter core will be caused like this to occur vibrations sound, working environment is affected, and the overgenerous words of vibrations easily cause the damage of filter core, make greatly reduce service life.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of air cleaner, by filter core inlay card between seal cover and filter body, and then utilize the screw rod passed from centre to fix, make pressure from center toward surrounding radiation, ensure that fixing the stablizing of filter core, also can be for convenience detach.
For achieving the above object, the utility model provides following technical scheme: a kind of air cleaner, comprise filter body, seal cover, the filter core for filtering is provided with in described filter body, described filter core is hollow structure, described filter body inwall bottom surface is provided with the draw-in groove with described filter core end face inlay card, described filter body bottom surface is also provided with the bulge loop with described filter core inwall inlay card, described filter body is provided with the venthole for giving vent to anger, and described venthole is provided with the escape pipe with venthole hole wall inlay card, fixed support is provided with in described escape pipe, described fixed support is equipped with the screw rod be threaded with described seal cover.
The utility model is set to further: described venthole is provided with groove, and described escape pipe is provided with the projection with described groove inlay card.
The utility model is set to further: the quantity of described groove is two, and all located on a straight line.
The utility model is set to further: be equipped with some reinforcements inside and outside the bulge loop of described seal cover inwall, described reinforcement circumferentially.
The utility model is set to further: described screw rod is provided with nut, and described seal cover is fixed on described filter body by nut extruding.
Compared with prior art, the utility model has the advantage of, by filter core inlay card between seal cover and filter body, and then utilize the screw rod passed from centre to fix, seal cover is pressed in above filter body by screw rod in the middle of utilizing all the time, and pressure is from center toward surrounding radiation.And the structure of draw-in groove and bulge loop tightly can fix filter core under the effect of the pressure, guarantee that filter core there will not be and significantly shake, decrease the generation of noise, also ensure that fixing the stablizing of filter core simultaneously, also can be for convenience detach.

Detailed description of the invention
Referring to figs. 1 through Fig. 7, the utility model air cleaner embodiment is described further.
A kind of air cleaner, comprise filter body 1, seal cover 2, filter body 1 is columniform, and seal cover 2 is circular, seal cover 2 have above one with the annular groove of filter body 1 inlay card, annular groove can be guaranteed that seal cover 2 blocks and can not leak gas on the filter.Be provided with the filter core 3 for filtering in described filter body 1, described filter core 3 is hollow structure, is also cylindrical shape, and top and seal cover 2 are conflicted, and bottom and filter body 1 inwall are conflicted, and is concentric setting with filter body 1.
Described filter body 1, the inwall of filter core 3 is equipped with the draw-in groove 41 with described filter core 3 outer wall inlay card, described filter body 1, the inwall of filter core 3 is also provided with the bulge loop 42 with described filter core 3 inwall inlay card, described filter body 1 is provided with the venthole for giving vent to anger and utilizes the air inlet pipe 16 of air inlet, and described venthole is provided with the escape pipe 11 with venthole hole wall inlay card, fixed support 12 is provided with in described escape pipe 11, described fixed support 12 is equipped with the screw rod 13 be threaded with described seal cover 2, the position of venthole and screw rod 13 is positioned on the axis of filter body 1, can guarantee that the uniform past surrounding radiation of fixation pressure in the middle of position is come like this.
By filter core 3 inlay card between seal cover 2 and filter body 1, and then utilize the screw rod 13 passed from centre to fix, seal cover 2 is pressed in above filter body 1 by screw rod 13 in the middle of utilizing all the time, and pressure is from center toward surrounding radiation.And draw-in groove 41 and the structure of bulge loop 42 tightly can fix filter core 3 under the effect of the pressure, guaranteeing that filter core 3 there will not be significantly shakes, and decreases the generation of noise, also ensure that fixing the stablizing of filter core 3 simultaneously.
Wherein, described venthole is provided with groove 15, and described escape pipe 11 is provided with the projection 111 with described groove 15 inlay card, and the quantity of described groove 15 is two, and all located on a straight line.Allow the direct inlay card of escape pipe 11 so very easily on filter body 1; there will not be displacement etc.; because escape pipe 11 can be connected with the breather pipe in the external world above usually; therefore fixing not revolvable escape pipe 11 is necessary; in the present embodiment; escape pipe 11 is provided with screw thread, can be connected with the gas-pipe thread in the external world.The structure installment of this clamping removes very convenient, and displacement one straight line is guaranteed stability under loading between the two, groove 15 is not easy to occur deformation.
Wherein, be equipped with some reinforcements 21 inside and outside the bulge loop 42 of described seal cover 2 inwall, described reinforcement 21 circumferentially.Described screw rod 13 is provided with nut 14, and described seal cover 2 is fixed on described filter body 1 by nut 14 extruding.
Reinforcement 21 can guarantee the fixing of bulge loop 42, because nut 14 is fixed on seal cover 2, therefore local pressure is larger above for top seal lid 2, if the tension that nut 14 sometimes can be twisted when twisting, the easy like this deformation causing bulge loop 42, the bulge loop 42 that goes down for a long time may cause the deformation of irrecoverability, and reinforcement 21 can strengthen overall structure, guarantees that bulge loop 42 is not easy to occur deformation.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
