Woven fabric 30;It is set to the air inlet 40 of 11 downside of compression chamber, air inlet 40 installs breather check valve 41;It is respectively arranged at compression chamber
The piston 50 at 11 both ends;Drive the drive component 60 of piston 50;It is driven by drive component 60 and wears compression chamber 11 to central mistake
The decontamination shaft 70 of mouth 20 is filtered, the hollow and end ring towards water proof nonwoven cloth 30 of decontamination shaft 70 sets sweep-up pipe 80, sweep-up pipe
80 connection decontamination shafts 70;And the bend pipe 90 of decontamination shaft 70,90 end set solenoid valve 91 of bend pipe are connected to by flange.
In an embodiment of the present invention, outer housing 10 has the compression chamber 11 being connected to by central filter mouth 20 and water storage
Chamber 12, compression chamber 11 are completed internal piston using piston 50 and are moved, by 40 air inlet of air inlet, suck ambient air, then press
Contracting, then storage chamber 12 is emitted by water proof nonwoven cloth 30, it is finally filtered by the water in storage chamber 12, realizes air purification, knot
Structure is simple.Drive component 60 drives 50 energy-saving convenient of piston, highly practical.It is noted that water proof nonwoven cloth 30 is by gathering
Allyl resin is main production raw material, then the fibre made of fine fibre, and waterproof and breathable, tough physical property is good, in the present invention
In the air purifier of offer, the water that on the one hand can be effectively isolated in storage chamber 12 prevents from revealing;On the other hand it can also adsorb
Particle is polluted, is effectively collected, secondary pollution is avoided, improves air purification effect.
Breather check valve 41 is articulated in 40 side of air inlet, is set as en plaque, and the other end is another by being fixed on air inlet 40
The limited block 42 of side supports, and when piston 50 bounce back, 11 internal pressure of compression chamber reduction, check valve will lift, open into
Gas port 40 realizes air inlet.When piston 50 compresses, 11 internal pressure of compression chamber rises, and check valve will decline, and contradicts limited block
42, air inlet 40 is closed, compressed air to 30 filtration, purification of water proof nonwoven cloth is simple in structure, easy to use.
Drive component 60 includes driving motor 61;The driving gear 62 driven by driving motor 61;Connect driving motor 61
And the crank connecting link 63 of driving gear 62 is worn, crank connecting link 63 connects left hand piston 50;Engage the central tooth of driving gear 62
Wheel 64, central gear 64 wear decontamination shaft 70;And the driven gear 65 of engagement central gear 64, driven gear 65 is by wearing
If crank connecting link 63, right hand piston 50 is driven.In an embodiment of the present invention, driving motor 61 is separately provided one, passes through
Gear-linked is driven to respectively on two pistons 50 of 11 left and right ends of compression chamber, and realization moves synchronously, and is saved the energy, is avoided
It is driven using two motors, saves cost.It is to be understood that crank connecting link 63 is made of crank and connecting rod, power is completed
Transmission, the present invention do not repeat herein.
60 operation principle of this drive component is specifically, bent when driving motor 61 drives left crank connecting rod 63 to rotate
Handle connecting rod 63 drives the left side in compression chamber 11 of left hand piston 50 to move back and forth, closer or far from water proof nonwoven cloth 30, to inhale
Receipts and compressed air;Driving gear 62 is driven by driving motor 61 and is rotated simultaneously, and driven gear 65 is driven by central gear 64,
Drive right crank connecting rod 63 to rotate, right hand piston 50 driven to be moved back and forth on 11 right side of compression chamber, closer or far from waterproof without
Woven fabric 30, similarly absorption and compressed air, complete the absorption of external ambient air and purification.
In addition, central gear 64 can also drive decontamination shaft 70 that sweep-up pipe 80 is driven to rotate, and the sealing of 80 both ends of sweep-up pipe, axis
To the thin mouth of dust suction of the arrangement towards water proof nonwoven cloth 30 81.In the present embodiment, because water proof nonwoven cloth 30 needs to filter dirt
Air is contaminated, inevitable surface layer can adsorb a large amount of pollution particle, at this point, the solenoid valve 91 on bend pipe 90 is opened, in piston
During 50 movements, due to internal and external pressure difference, the pollution particle on surface layer will be passed through the thin mouth of the dust suction of rotation by pressure action
81 high speed sucking sweep-up pipes 80, and as decontamination shaft 70 excludes, facilitate user's collection to handle, while also cleaning water proof non-woven
Cloth 30 reduces the influence to filtration, purification, improves durability, keeps purification efficiency.
It is noted that 70 upper end of decontamination shaft is to be fixed on central filter mouth 20 by bearing, stability, side are kept
Just decontamination shaft 70 rotates, and is tightly connected water proof nonwoven cloth 30, it is ensured that sealing performance.
Next, please also refer to Fig. 1 and Fig. 2, Fig. 2 is that the partition board 100 of the embodiment of the present invention and pressure check valve 111 are pacified
Fill schematic diagram.As shown, the invention also includes the isolation boards being set in compression chamber 11 and positioned at 30 both sides of water proof nonwoven cloth
100, two side pistons 50 and water proof nonwoven cloth 30 is isolated in isolation board 100, and is provided with and is circulated to water proof non-woven by 50 side of piston
The pressure check valve 110 of 30 side of cloth.In an embodiment of the present invention, isolation board 100 is mounted on 30 both ends of water proof nonwoven cloth,
Separator piston 50 is limited, is played a protective role;Pressure check valve 110 unidirectionally plays on or off with 50 movement of piston effect simultaneously
It closes, realizes air inlet when closing, compression purification when opening.
Specifically, pressure check valve 110 includes being set to the cone hole part 111 of isolation board 100;In cone hole part 111
Gag lever post 112;It is sheathed on the spring 113 of gag lever post 112;And it is arranged in the ball 114 of gag lever post 112,114 both ends of ball
Cone hole part 111 and spring 113 are contradicted respectively;Wherein, cone hole part 111 is gradually big along 30 direction aperture of water proof nonwoven cloth.In this implementation
In mode, gag lever post 112 supports ball 114 to cone hole part 111 by spring 113 so that pressure of the ball 114 by spring 113
Limit is only butted on cone hole part 111.When piston 50 is shunk, both sides compression chamber 11 can be closed, improves the air inlet effect of air inlet 40
Rate;And when piston 50 compresses, air inlet 40 is closed, and ball 114 will be detached by pressure with cone hole part 111 so that gas pressure
Contracting is directed to water proof nonwoven cloth 30, completes purification filtering, simple in structure, easy to use, ensures to improve again while safety
Purification efficiency.
In addition, the present invention compression chamber 11 in be arranged pressure gauge 200, pressure gauge 200 between both sides isolation board 100,
Pressure gauge 200 can understand that the pressure between isolation board 100 can when reflecting the movement of both ends piston 50 in compression chamber 11
Solenoid valve 91 is opened or closed according to actual demand, facilitates the dust suction decontamination of decontamination shaft 70, improves purification efficiency, practicality side
Just.
