Description

Cleaning-free laser dust detector

Technical Field

The utility model relates to the technical field of dust detection, in particular to a cleaning-free laser dust detector.

Background

The laser dust detector is one of dust detectors, can be generally divided into the laser dust detector, the micro-weight balance and the beta-ray dust detector according to the detection principle, is relatively commonly used in China, is used for detecting dust concentration in labor sanitation aspects such as industrial and mining enterprise production sites and the like, can be used for monitoring the concentration of inhalable dust in the field of environmental protection, can be used for evaluating the purification efficiency of an air purifier, is very popular and wide in use, and has a certain demand for a cleaning-free laser dust detector for occupational health detection along with the development of technology.

The structure that current laser dust detector utilized the fan to remove dust more, but the dust was adsorbed at the structure inner wall easily, and the fan can't be with its clean up, long-term in the past, pile up easily at the structure inner wall, lead to the dust removal effect to descend, also have some structures to utilize the brush to carry out dust treatment to the inner wall, but the brush also can remain partial dust, if the brush can not get cleanly, can influence the measurement accuracy of detector for a long time, need exempt from to wash formula laser dust detector now solves above-mentioned problem.

Disclosure of Invention

According to the technical problem, the utility model provides a cleaning-free laser dust detector which is characterized by comprising a detection tube, a laser detector, a dust collector, a mini fan, a spring, a containing groove, a limiting through hole, a limiting rod, a dust exhaust tube, a limiting block and a sleeve.

The dust collector is characterized in that the lower part of the detection tube is fixedly connected with the dust collector, a laser detector is arranged at the top of the dust collector and is positioned in the detection tube, the laser detector is fixedly connected with the inner wall of the detection tube, the detection tube is fixedly connected with the sleeve, a containing groove is formed in the sleeve, the containing groove is fixedly connected with the spring, the spring is connected with the dust exhaust tube in a contact mode, the right side of the dust exhaust tube is in an opening shape, the left side of the dust exhaust tube is in a closed shape, the left side of the dust exhaust tube is internally connected with the mini fan fixedly, a limiting through hole is formed in the wall of the sleeve, the outer wall of the dust exhaust tube is fixedly connected with one end of the limiting rod, an acute angle is formed between the outer wall of the dust exhaust tube and the limiting rod, and the other end of the limiting rod is fixedly connected with the limiting rod.

The sleeve is fixedly connected with the fixed plate through screws, and the fixed plate is provided with vent holes.

The casing pipe and the dust exhaust pipe wall are both provided with dust inlets.

The casing bottom and detection casing fixed connection, the detection casing is provided with operating button and display screen, the inside battery and the mainboard of being provided with of detection casing, battery and mainboard wire connection, mainboard and laser detector and mini fan wireless connection, the mainboard respectively with operating button and display screen wire connection.

The utility model has the beneficial effects that: the existing laser dust detector utilizes a hairbrush to carry out dust treatment on the inner wall, but part of dust can be reserved in the hairbrush; according to the utility model, the dust discharging pipe and the sleeve are arranged into a detachable structure, the dust discharging pipe is detachably connected with the sleeve through the limiting through hole, the limiting block, the spring and the fixing plate, a user places the dust discharging pipe into the sleeve, places one side of the fan in the dust discharging pipe close to the spring and fixes the fan through the fixing plate, so that detected dust can be discharged out of the laser dust instrument, the dust discharging pipe can be detached and cleaned regularly, and the situation that the instrument is inaccurate in measured value due to dust accumulation is further reduced.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model:

embodiment 1, when using, detect pipe 1 and sleeve pipe 4 fixed connection, the inside holding tank of having seted up of sleeve pipe 4, holding tank and spring fixed connection, spring and dust exhaust pipe 13 contact connection, dust exhaust pipe 13 right side is the opening form, dust exhaust pipe 13 left side is the closure form, dust exhaust pipe 13 left side is inside and mini fan 5 fixed connection, spacing through-hole 9 has been seted up to sleeve pipe 4 pipe wall, dust exhaust pipe 13 outer wall and gag lever post 10 one end fixed connection, the angle is the acute angle between dust exhaust pipe 13 outer wall and the gag lever post 91, the gag lever post 10 other end and stopper 91 fixed connection.

Working principle: after the detected dust is sucked to the dust discharging pipe 13 by the dust collector 3, the mini fan 5 sends the dust out of the dust discharging pipe 13, the dust discharging pipe 13 is detachably connected with the sleeve 4 through the limiting through hole 9, the limiting block 91, the spring and the fixing plate 7, a user puts the dust discharging pipe 13 into the sleeve 4, one side of the mini fan 5 in the dust discharging pipe 13 is close to the spring, and after the limiting block 91 exists in the limiting through hole 9, the fixing plate 7 is fixed with the sleeve 4 through a screw;
