Fig. 1 shows the schematic cross-sectional view of the embodiment of dust catcher according to the present utility model.As shown in Figure 1, this The dust catcher of embodiment includes body 10, dust-collecting cylinder 20, wind turbine 30, inductor 40 and controller.Wherein, it is provided on body 10 Air inlet and air outlet, dust-collecting cylinder 20 are arranged on body 10.The entrance of dust-collecting cylinder 20 is connected with air inlet, and dust-collecting cylinder 20 includes Cylinder 21 and the filtration 22 being arranged in cylinder 21, the solid sucked from the air inlet of body 10 are hindered by filtration 22 Every staying in cylinder 21；The gas sucked from the air inlet of body 10 is flowed out by filtration 22 from the outlet of dust-collecting cylinder 20. Wind turbine 30 is arranged in body 10, and the import of wind turbine 30 is connected with the outlet of dust-collecting cylinder 20, outlet and the body 10 of wind turbine 30 Air outlet is connected.Inductor 40 is arranged between the outlet of dust-collecting cylinder 20 and the import of wind turbine 30, when the outlet stream of dust-collecting cylinder 20 When going out solid, inductor 40 sends out inductive signal, and wind turbine 30 is controlled when controller receives inductive signal and is stopped.

Using the technical solution of the present embodiment, when the wind turbine 30 of dust catcher operates, air and the rubbish being inhaled into air, Dust, clast etc. along dust catcher duct flows.Specifically, the pollutants such as air and rubbish, dust, clast from body into Air port enters, and by dust-collecting cylinder 20, the solid pollutants such as rubbish, dust, clast are hindered by the filtration 22 of dust-collecting cylinder 20 at this time Every, and be collected in cylinder 21 and realize cleaning effect；Air by filtration 22, by 40 cocurrent of inductor to wind turbine 30, finally body 10 is flowed out from the air outlet of body 10.When occur between the building block aging of dust-collecting cylinder 20, component gap, When having solid pollutant to be flowed out from dust-collecting cylinder 20, solid pollutant will trigger inductor 40, induction when by inductor 40 Device 40 sends out inductive signal to controller after being triggered, controller will be by power-off or other modes when receiving inductive signal Control wind turbine 30 is stopped, and avoids solid pollutant from entering wind turbine 30, wind turbine 30 is protected not to be damaged.Even if user is in wind turbine Dust catcher is restarted after 30 shutdown, solid pollutant is still had and is flowed out from dust-collecting cylinder 20 and trigger inductor 40, in turn It again leads to wind turbine 30 to be stopped, until the problem of causing solid pollutant to flow out from dust-collecting cylinder 20 is solved.

Specifically, as shown in Figure 1, the entrance in wind turbine 30 is arranged in inductor 40.According to actual function needs, dust Other structures can be set between cylinder 20 and wind turbine 30, compared with being arranged inductor 40 in the exit of dust-collecting cylinder 20, induction Device 40 is arranged close to wind turbine 30, make inductor 40 it is more acurrate it is reliable judge whether there is solid and enter wind turbine 30, more effectively protect It is injury-free to protect wind turbine 30.

Further, Fig. 2 shows partial enlargement structural representations at the A of the dust catcher of Fig. 1；Fig. 3 is shown with Fig. 2's The structural schematic diagram of the opposite inductor of inductor.As shown in Figure 1 to Figure 3, the inductor 40 of the present embodiment is 3,3 inductions Device 40 is separately positioned on the opposite both sides of import of wind turbine 30.

Specifically, as shown in Fig. 2, the side of the import of wind turbine 30 is provided with 2 inductors 40.As shown in figure 3, with above-mentioned The other side that the import of wind turbine 30 is opposite is provided with 1 inductor 40, the side where 1 inductor 40 to 2 inductors On projection be located between 2 inductors 40, that is, multiple inductors 40 in the both sides of the import of wind turbine 30 are set in vertical side Upward interlaced arrangement.

According to the size and other factors of the import of wind turbine 30, the quantity of inductor 40 could be provided as 2, or It 4 or more, to reduce the gap between inductor 40, avoids leaking through solid pollutant.

In the present embodiment, 3 settings of inductor 40 in the same plane, further increase the covering surface of inductor 40 Product.

Preferably, as shown in Figures 2 and 3, in the present embodiment, above-mentioned plane is vertical with the direction that gas flows, and makes suction Dirt device can use the inlet -duct area of the covering wind turbine 30 of inductor 40 few as possible.In other unshowned other embodiments, As long as the direction that plane is flowed with gas is angularly arranged, can be transferred through being arranged multiple inductors makes inductor cover entire wind The import of machine.The mode that is vertically arranged of the present embodiment has chosen most efficient set-up mode.

Preferably, the inductor 40 of the present embodiment is infrared probe.3 infrared probes can make in being generally aligned in the same plane The infrared-ray of infrared probe also in this plane, is easy to implement the inlet -duct area of inductor covering wind turbine.

Further, in the present embodiment, dust catcher further includes indicator light, when inductor 40 sends out inductive signal, control Device control indicator light processed lights.Meanwhile the dust catcher of the present embodiment further includes alarm, when inductor 40 sends out inductive signal When, controller control alarm sounds.Indicator light and alarm actively prompt user's dust catcher event occur by light and sound Barrier, needs to be adjusted or repair, enable the customer to correspondingly make renewal part or be sent to the judgement of after-sales service.

Further, to avoid the solid pollutant of triggering inductor 40 from entering wind turbine 30, as shown in Figure 1 to Figure 3, at this In embodiment, the entrance of wind turbine 30 is provided with import frame 31, and inductor 40 is arranged on the inner wall of import frame 31, and dust catcher is also Including being arranged in import frame 31 and positioned at the filtration 50 in 40 downstream of inductor.Filtration 50 will trigger inductor 40 Solid pollutant is blocked in import frame 31, and second protection is played to wind turbine 30.

It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：

Dust catcher wind turbine operating when, air and the rubbish being inhaled into air, dust, clast etc. along dust catcher wind It flows in road.Specifically, the pollutants such as air and rubbish, dust, clast enter from the air inlet of body, by dust-collecting cylinder, at this time The solid pollutants such as rubbish, dust, clast are obstructed by the filtration of dust-collecting cylinder, and are collected in cylinder and are realized cleaning effect Fruit；Air by filtration, by inductor cocurrent to wind turbine, finally from the air outlet of body flow out body.Work as dust-collecting cylinder Building block aging, when there is gap between component, thering is solid pollutant to be flowed out from dust-collecting cylinder, solid pollutant will pass through Inductor is triggered when crossing inductor, inductor sends out inductive signal to controller after being triggered, controller receives inductive signal When will by power-off or other modes control wind turbine be stopped, avoid solid pollutant from entering wind turbine, protect wind turbine not by Damage.Even if user restarts dust catcher after fan parking, still has solid pollutant and flow out and touch from dust-collecting cylinder Inductor is sent out, and then wind turbine is again led to and is stopped, until the problem of causing solid pollutant to be flowed out from dust-collecting cylinder is solved Certainly.
