Preferably, described filter and support contact position are provided with cushion.
Preferably, described air pump is 2 and is connected with filter and probe respectively.
Compared with prior art, the invention has the beneficial effects as follows：The dust detection case of this teaching; using many siphunculus, casing is divided into two parts, a part produces clean air by filter, protects the electronic devices and components of box house not polluted by under test gas; another part passes through probe and other detecting elements realize detection; structure is simple, and casing is petite, facilitates pupil to carry; tank surface is embedded in using display screen and control knob; save space, not only pupil operate and be easily understood, and teacher explanation get up convenient.
Brief description
Fig. 1 is present configuration schematic diagram；
Fig. 2 is control panel plane graph of the present invention.
In figure：1 casing, 2 air inlet pipe, siphunculus more than 3,4 air pumps, 5 filters, 6 escape pipes, 7 laser diodes, 8 lens group, 9 probes, 10 photoelectric detectors, 11 Main Control Tanks, 12 display screens, 13 control knobs.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of protection of the invention.
Refer to Fig. 1-2, the present invention provides a kind of technical scheme：A kind of dust detection case of teaching，Including casing 1，The left-hand face of casing 1 offers control panel，Control panel includes display screen 12 and control knob 13，Control knob 13 is arranged on left side and the downside of display screen 12 with semi-surrounding form，Control knob 13 electrically connects Main Control Tank 11 with display screen 12，The top left side of casing 1 is through with air inlet pipe 2，The afterbody of air inlet pipe 2 is connected with many siphunculus 3，Many siphunculus 3 pass on left the inlet end that air pump 4 is connected with filter 5，Air pump 4 is 2 and is connected with filter 5 and probe 9 respectively，Filter 5 is fixedly mounted on the inside of casing 1 by support，Filter 5 and support contact position are provided with cushion，The outlet side of filter 5 is connected with exhaustor 6，The right side of many siphunculus 3 is connected with probe 9 by air pump 4，The side of probe 9 is provided with lens group 8，The left side of the lens group 8 and right side of filter 5 is provided with laser diode 7，The opposite side of probe 9 is provided with photoelectric detector 10，The inside of the casing 1 and lower section of lens group 8 is provided with Main Control Tank 11，The electrical connection air pump 4 of Main Control Tank 11、Filter 5、Laser diode 7 and photoelectric detector 10，The dust detection case of this teaching，It is divided into two parts using many 3 casings 1 of siphunculus，A part produces clean air by filter 5，The electronic devices and components within casing 1 are protected not polluted by under test gas，Another part passes through pop one's head in 9 and the realization detection of other detecting elements，Structure is simple，Casing 1 is petite，Pupil is facilitated to carry，Casing 1 surface is embedded in using display screen 12 and control knob 13，Save space，Not only pupil operates and is easily understood，And teacher explanation get up convenient.
