Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 3, the utility model is the air cleaner with spring drainage mechanism, including filter body 1, mistake
It is provided with filter body 1 and is provided with what is be fixedly connected with filter body 1 in the housing 5 being arranged outside cup 2 and cup 2, cup 2
Filter assemblies 6, the lower end of cup 2 is provided with perforate 21, and spring drainage mechanism 3 is provided with perforate 21.
Filter assemblies 6 include cyclone blade 61, filter core 62, water bloking piece 63 and fix bar 64, and water bloking piece 63 is arranged at fixation
The lower end of bar 64, the upper end of fix bar 64 is fixedly connected with filter body 1, and filter core 62 is sheathed on fix bar by water bloking piece 63
On 64, cyclone blade 61 is set in the outside of filter core 62.Water bloking piece 63 can prevent the compression with profit or other impurities
Air enters filter core 62 from the lower end of filter core 62.Compressed air is entered in filter body 1 from gas source inlet 11, through cyclone leaf
The breach of the tangential direction of piece 61 rotates strongly, liquid profit and solid impurity centrifugal action in compressed air, is thrown to
On the side wall of cup 2, then along the surface current of cup 2 to the bottom of cup 2, compressed air is after the filtration treatment of filter core 62 from source outlet
12 discharges.
As shown in figure 4, spring drainage mechanism 3 includes the hollow draining valve body 31 that card is set in perforate 21, wherein perforate
21 be stepped hole, and the upper end aperture of stepped hole is more than lower end aperture, and one end that draining valve body 31 is located inside cup 2 is provided with opening
The annular boss 311 that the upper end interporal lacuna in hole 21 coordinates, is arranged between annular boss 311 and the upper end hole step surface of perforate 21
First sealing ring 41, the first sealing ring 41 seals the junction of draining valve body 31 and perforate 21.In hollow draining valve body 31
Provided with spring 33 and by the drain plug 34 of the jack-up of spring 33, drain plug 34 is interior to be provided with drainage channel 341, drain plug 34
Formed with the madial wall of draining valve body 31 and communicated drainage passage 341 is transversely provided with the passage 342 that discharges water, drain plug 34 and is discharged water
The through hole 343 of passage 342, and the second sealing ring 42 of the salable passage 342 that discharges water is arranged with drain plug 34.Draining valve
The threaded one end that body 31 stretches out cup 2 is connected with hollow draining bonnet 32, and the screw thread of draining bonnet 32 and draining valve body 31 connects
Annular groove 321 is opened up above the place of connecing, while setting rim of a cup and annular groove 321 with cup 2 respectively in annular groove 321
The 3rd sealing ring 43 that bottom surface is abutted against.3rd sealing ring 43 seals perforate 21 in the outside of cup 2.Due to the 3rd sealing ring 43
Setting, it is therefore prevented that the profit in cup 2 passes through clearance flow between the first sealing ring 41 and draining valve body 31 and the inwall of perforate 21
To outside air cleaner, overall sealing effectiveness is improved.Draining bonnet 32 is screwed on into draining valve body 31 for convenience simultaneously,
Therefore circumferentially it is uniformly arranged axial anti-slip tank 322 in the lateral wall of draining bonnet 32.
As shown in Figure 3 and Figure 5, the outside of cup 2 is arranged housing 5, and the bottom of cup 2 is conical cavity 22, the cone
Shape chamber 22 is gradually reduced close to the bottom level area of section of cup 2, and the place lateral wall of conical cavity 22 sets reinforcement 23, reinforcement
23 is inconsistent with the madial wall of housing 5.Meanwhile, the port side wall internal diameter of housing 5 reduces, with cup 2 in interference fit.
As shown in Figure 3 and Figure 6, when the cup 2 and filter body 1 are engaged, the madial wall of filter body 1
Set in the annular groove formation toroidal cavity 24 that the annular groove of setting is set with the upper port lateral wall of cup 2, the toroidal cavity 24
Put the rubber seal 44 that size is more than toroidal cavity 24.This set makes cup 2 be fixed on filter body 1, and water
The junction of cup 2 and filter body 1 is sealed by rubber seal 44.
As shown in Figure 3 and Figure 6, the lateral wall of housing 5 is axially uniformly arranged strip through hole 51.Strip through hole can be passed through
The 51 observation inner cases of cup 2, are monitored in real time.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
