Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.
The concrete structure of the utility model first embodiment as depicted in figs. 1 and 2.
Air purifier comprises framework 10 and the centrifugal fan 20 that is located in framework 10 and screen pack.The screen pack energy filtration, purification particle of the present embodiment, organic chemical pollutant and germ.
Framework 10 comprises the front framework 11 and rear framework 12 that are mutually permanently connected.Front framework 11 is provided with the air channel 111 for holding a centrifugal fan 20.Centrifugal fan 20 is fixed on the centre position in air channel 111 by installing rack 21.In the present embodiment, centrifugal fan 20 has two, and therefore air channel 111 also has two.Two air channels 111 are located on same vertical plane side by side, and the axis in air channel 111 is all perpendicular to vertical plane.
Rear framework 12 is provided with the air intake cavity 121 in corresponding air channel 111.Air intake cavity 121 also has two.In actual production, rear framework can be arranged the air intake cavity of more than 1 or 1.When rear framework only being arranged 1 air intake cavity, multiple rear framework needs to be arranged on side by side on same vertical plane.And when rear framework being arranged more than 1 air intake cavity, for example in the present embodiment, front framework 11 has 2 air channels 111, rear framework 12 also there is the air intake cavity 121 in 2 corresponding air channels 111, so, framework 12 just can global formation, rear framework 12 can arrange less installing component, the integral thickness size of air purifier can be reduced like this, also reduce installation procedure, reduce costs.
The air inlet 112 in air channel 111 and air outlet 114 are all on the axis in air channel 111, and the axis of centrifugal fan 20 overlaps with the axis in air channel 111.That is to say, the air intake direction in air channel 111 is identical with air-out direction and be parallel to the axis in air channel 111.The air inlet 112 in air channel 111 is located on cylinder type air intake passage 113, and faces centrifugal fan 20.The incoming air area of air intake passage 113 diminishes from outside to inside gradually.The cross section of inboard wall of air intake passage 113 is the circular arc of indent, and the whirlpool produced during to reduce air flowing, reduces the loss of air energy of flow.
In addition, for convenience of producing, the sidewall of air channel 111 and air intake cavity 121 is equipped with pattern draft.
In addition, make an uproar for reducing wind, the shape of cross section in air channel 111 from the inside to the outside from circle gradually transition be square.In air channel 111, direction is from the inside to the outside the direction pointing to air outlet 114 from air inlet 112.
Screen pack comprises for the airfiltering inlet air filter screen 32 for entering air intake cavity 121, and inlet air filter screen 32 is arranged at the rear side of rear framework 12.The rear side of rear framework 12 is the rear in air intake direction, after air-flow needs just to enter into after inlet air filter screen 32 in framework 12.
The outside of inlet air filter screen 32 is provided with air intake screen 34.The outside of inlet air filter screen 32 is the rear in air intake direction, and air needs first just through the filtration of inlet air filter screen 32, then just to enter in rear framework 12 after air intake screen 34.Air intake screen 34 is made detachable, to facilitate cleaning.In other embodiments, air intake screen also can to make non-dismountable formula, and air intake screen also can replace with air intake orifice plate or air intake web plate.
Screen pack also comprises the air-out screen pack 31 for filtering the air sprayed from the air outlet 114 in air channel 111, and air-out screen pack 31 is located at the front of front framework 11.The front of front framework 11 is the front of air-out direction, from air channel 111 spray air leave air channel 111 after just can through the filtration of air-out screen pack 31.
The outside of air-out screen pack 31 is also provided with air-out screen 33.The outside of air-out screen pack 31 is the front of air-out direction, and the air sprayed from air channel 111 just arrives the external world through air-out screen pack 31, air-out screen 33 successively.Air-out screen 33 is made detachable, to facilitate cleaning.In other embodiments, air-out screen also can to make non-dismountable formula, and the screen of air-out simultaneously also can replace with air-out orifice plate or air-out web plate.
In actual production, for embodying different product hierarchy levels, air-out screen pack and inlet air filter screen only can install one of them, also can both be installed on air purifier.
During air purifier work, air enters in air intake cavity 121 through air intake screen 32, inlet air filter screen 34 successively, then enters in the air intake passage 113 in air channel 111 from air intake cavity 121.Air inlet 112 through air channel 111 after air is accelerated in air intake passage 113 enters in centrifugal fan 20, assembles formation malleation then spray from the air outlet 114 in air channel 111 from centrifugal fan 20 air out air channel 111 in.The air sprayed from the air outlet 114 in air channel 111 arrives extraneous successively after air-out screen pack 33, air-out screen 33.
The concrete structure of the second embodiment as shown in Figure 3.The main difference point of the second embodiment and the first embodiment is the number of centrifugal fan.In second embodiment, centrifugal fan 220 has 4, and corresponding air channel 211 also has 4.Similarly, 4 air channels 211 are located on same vertical plane side by side, and the axis in air channel 211 is all perpendicular to vertical plane.If the second embodiment is the same with the incoming air area of the first embodiment, so centrifugal fan and motor can do smaller, and noise can be less.
The concrete structure of the 3rd embodiment as shown in Figure 4.The main difference point of the 3rd embodiment and the first embodiment is the number of centrifugal fan.In 3rd embodiment, centrifugal fan 320 has 6, and corresponding air channel 311 also has 6.Similarly, 6 air channels 311 are located on same vertical plane side by side, and the axis in air channel 311 is all perpendicular to vertical plane.
It should be noted that, in the embodiment above, in air purifier, the number of centrifugal fan is even number, but in other embodiments of the present utility model, ensureing that the number of centrifugal fan is more than under the prerequisite of 1, the utility model does not specifically limit the number of centrifugal fan.
In addition, multiple centrifugal fan associated working is enough to meet the requirements of operating efficiency, and by adopting the centrifugal fan of varying number, the air purifier of different volumes size is set, air purifier of the present utility model can be made can be applied to different use occasion, as vehicle-mounted, indoor or public place etc.
More than state only with embodiment to further illustrate technology contents of the present utility model; so that reader is easier to understand; but do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
