Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, the utility model provides a kind of warning device for preventing plugged filter, including intake valve 1, sky
Filter core 4 and air filter 5, the inlet end of intake valve 1 connect air filter 5 by air inlet pipe 2, were easy to air filtering, and make the sky after filtering
Gas is entered in intake valve 1 by air inlet pipe 2, and the junction of air filter 5 and air inlet pipe 2 is provided with air filter core 4, the side of air inlet pipe 2
Be welded with blast pipe 3, valve 10 be installed on blast pipe 3, by valve 10 control blast pipe 3 break-make, air inlet pipe 2 it is another
Side connects pressure difference alarm 7 by attaching nut 9, and pressure difference switch 8 is provided with pressure difference alarm 7.
Air filter core 4 is arranged in air filter 5, and air filter core 4 and air filter 5 are fastened on air inlet pipe 2 by air filter clamp nut 6
On, it is easy to fix air filter core 4 and air filter 5.
Air filter clamp nut 6 is arranged on the top of air filter 5, is easy to rotate air filter clamp nut 6, so that air filter 5 fastens
Or unclamp, it is conveniently replaceable air filter core 4.
It is provided with battery and alarm in pressure difference alarm 7, and battery is by wired in series alarm and pressure difference switch 8,
Connecting and disconnecting of the circuit between battery and alarm is controlled by pressure difference switch 8, so as to control the power on/off of alarm, controls pressure difference report
