Specific embodiment

It should be noted that word "front", "rear", "left", "right" used in the description of the utility model refer to it is attached Scheme the direction in (attached drawing 1 being primarily referred to as), word "inner" and "outside" are referred respectively to towards or away from particular elements geometry The direction of the heart.These are merely for convenience of describing the present invention and simplifying the description, rather than the device of indication or suggestion meaning Or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model Limitation.

The high-precision gas detector of the included cleaning device of the utility model mainly includes detector main body in structure 1, the gas access holes 11 inside multiple communication with detection instrument main bodys 1, detection are offered on 1 leading flank of detector main body (for plane) Plastic suckers 2 identical with 11 quantity of gas access holes are also incorporated on 1 leading flank of instrument main body, plastic suckers 2 are used and are pressed Mode be adsorbed on by sucker mouth on the leading flank of detector main body 1, each gas access holes 11 is inhaled by plastics respectively Disk 2 covers completely, and each one end of plastic suckers 2 far from sucker mouth is fixedly linked with the rear plate face of same panel 3,

Horizontal fixed link 13 is connected on the left side of detector main body 1,13 one end of fixed link is fixedly connected on detection The left side of instrument main body 1, left side of the other end far from detector main body 1,

Horizontal motion bar 31 is connected on the left side of panel 3,31 one end of motion bar is fixedly connected on the left end of panel 3 Face, left side of the other end far from panel 3,

The one of separate 3 left side of panel on one end and motion bar 31 in fixed link 13 far from 1 left side of detector main body It being connected between end by hinge axis 4, the setting of hinge axis 4 also limits the scope of activities of motion bar 31 and panel 3,

Panel 3 is that center axis rotates with hinge axis 4 under the driving of motion bar 31, so as to drive each plastic suckers 2 be adsorbed in or far from detector main body 1 leading flank；

It is located at 13 lower section of fixed link on 1 left side of detector main body and is also fixedly installed with air compression plant 12, air pressure Outlet pipe 121 is connected on compression apparatus 12, air compression plant 12 is blown outward by outlet pipe 121, outlet pipe 121 For flexible rubber tube,

When motion bar 31 is that center axis is rotated to (i.e. each modeling when forming 180 ° of angles between fixed link 13 with hinge axis 4 When material sucker 2 is sufficiently far from detector 1 leading flank of main body), by the air outlet on mobile outlet pipe 121, the outlet air can be made Mouth sucker mouth that is close and being directed at plastic suckers 2；

The lower end surface of detector main body 1 is equipped with charging interface 14, is located at charging interface on the lower end surface of detector main body 1 14 side is connected with rope 15, and 15 one end of rope is fixedly connected on the lower end surface of detector main body 1, and the other end is far from detection The lower end surface of instrument main body 1 is simultaneously fixedly connected with cover 5, and cover 5 covers charging interface 14, to avoid charging interface 14 by dust It corrodes.

Above-mentioned gas detector passes through sucker mouth in the case where not using, by plastic suckers 2 by the way of being pressed It is adsorbed on the leading flank of detector main body 1, divides each gas access holes 11 being similarly positioned on 1 leading flank of detector main body It is not covered completely (such as attached drawing 1) by a plastic suckers 2, the absorption of sucker 2 has good leakproofness, can will test instrument main body Gas access holes 11 on 1 leading flank is sufficiently isolated from the outside, and prevents sundries from entering in gas access holes 11, avoids to inspection The influence of precision is surveyed,

When needing to be detected using the gas detecting instrument, need sucker 2 through panel 3 on front side of detector main body 1 It is pulled away on face, during pulling away, sucker 2 also can generate certain suction in the duct to gas access holes 11, make originally The some sundries being present in duct are sucked out that (detector is not covered in use by sucker 2 after all, is had a small amount of Sundries enters in duct in this stage), catharsis is played, the influence to detection accuracy is avoided,

After the sundries being originally present in duct is sucked out, these sundries are easy to enter and stay in sucker by sucker mouth In 2 cavity, when sucker 2 being adsorbed in 1 leading flank of detector main body again at this time covering gas access holes 11, these sundries can also It re-enters into 11 duct of gas access holes.Therefore this programme is provided with air compression plant 12 and connects outlet pipe 121, Outlet pipe 121 can adjust at any time the position of air outlet on outlet pipe 121 using flexible rubber tube in air blowing process It sets, is carried out convenient for the cavity of (in the case where each plastic suckers 2 are sufficiently far from gas access holes 11) to each sucker 2 abundant High wind purging, sundries therein is produced by boasting.
