Description
Technical field
The present invention relates to a kind of dust electrometer treasure, belong to dust weight detection technique field.
Background technology
Haze weather is happened occasionally, and air quality is increasingly paid close attention to by people, inhalable especially in air
Grain thing, either outdoor or indoor, people want to understand content, the composition of dust in air, and each composition is to human body
Harm.At present, for the detection of dust particle, more accurately data are all that authoritative institution is gone out by the apparatus measures of specialty
Come, people can not understand air pollution situation anywhere or anytime, this be due to specialty measuring instrument costly.At present
In the market also sells hand-held laser dust counter, but it can only measure number of particles, volume in general unit volume, no
The quality of all particles can be helped with other data together in the quality of all particles, unit volume in energy units of measurement volume
Help others quick general understanding particle main component, the quality and number of particles, volume one of all particles in unit volume
Rise, particle averag density can be calculated.For example, when content containing metallic is beyond normal level in air, particle is average close
Degree will exceed the averag density of particle in normal air, be used as a significant data for judging air quality.
The content of the invention
The technical problems to be solved by the invention are：A kind of dust electrometer treasure is provided, it solves current equipment
The problem of quickly and easily can not being detected to the quality of all particles in unit volume in air.
The technical problems to be solved by the invention take following technical scheme to realize：
A kind of dust electrometer treasure, it is quick that it includes housing, blower fan, anion generator, anode dust piece, pedestal, depression bar, power
Resistance, high pressure nozzle, the shell one end be provided with air inlet, from air inlet to housing hollow in be sequentially provided with blower fan, anion
Generator, anode dust piece, the anode dust piece are fixed on depression bar one end, and the depression bar other end is movably fixed to base by bearing pin
On seat, pedestal is fixed in housing, and downside is provided with briquetting in the middle part of depression bar, and force sensing resistance is fixed on pedestal, below briquetting,
Force sensing resistance is contacted with briquetting, is provided with the housing below high pressure nozzle, anode dust piece and is opened up above the anode dust piece
There is air outlet.
It is located at as preferred embodiment, on the pedestal above depression bar and is provided with limited block.
The beneficial effects of the invention are as follows：Drawn air into by blower fan in anion generator so that negative electricity on particle band,
Negatively charged particle is built up by the absorption of anode dust piece, passes through the quick electricity of depression bar oppressive force under the particle Action of Gravity Field of accumulation
Resistance, according to the characteristic curve of force sensing resistance, the detection circuit being connected with force sensing resistance will detect all attachment particle weights；One
After secondary measurement, the particle on anode dust piece is blown off by high pressure nozzle, blown out by air outlet, to measure next time；Pressure
Limited block is provided with above bar, prevents depression bar from excessively swinging, internal structure is damaged.
Brief description of the drawings

The other end is movably fixed on pedestal 5 by bearing pin, and pedestal 5 is fixed in housing 1, and the middle part of depression bar 6 downside is provided with briquetting 9, power
Quick resistance 7 is fixed on pedestal 5, positioned at the lower section of briquetting 9, and force sensing resistance 7 is contacted with briquetting 9, and the top of anode dust piece 4 is provided with height
Press and offer air outlet 12 on nozzle 8, the housing 1 of the lower section of anode dust piece 4.
It is located at the top of depression bar 6 on pedestal 5 and is provided with limited block 10.
Drawn air into by blower fan 2 in anion generator 3 so that negative electricity on particle band, negatively charged particle is by anode
The absorption of dust piece 4 is built up, and force sensing resistance 7 is oppressed by depression bar 6 under the particle Action of Gravity Field of accumulation, according to force sensing resistance
7 characteristic curve, the detection circuit being connected with force sensing resistance 7 will detect all attachment particle weights；After one-shot measurement, pass through
High pressure nozzle 8 blows off the particle on anode dust piece 4, is blown out by air outlet 12, to measure next time；The top of depression bar 6 is set
Limited location block 10, prevents the excessively swing of depression bar 6, damages internal structure.
