According to lever ratio, calculate the emitted dose of aerosol, when emitted dose reaches preset value, cut-out jet drive button mechanism with it is straight
The electric current connection of power supply is flowed, inhalator jar is stopped injection.
It is blunt nosed and be placed on the mass of the blunt nosed top of taper that described balance weight mechanism includes inverted taper, described cone
The blunt nosed head of shape contacts connection with the pallet of balance.
Described support includes base and elevating lever, the top connection of described lever and elevating lever, and described balance leads to
Pole is crossed to be fixed on elevating lever.
The effect of each part of the present invention：
Inhale iron：Attracted to push by magnetic force after electromagnet energization, the nozzle injection of driving gas tank.
Back-moving spring：Suction iron is resetted after electromagnet power-off, stops injection.
Magnet coil (electromagnet)：Magnetic force is produced when being powered and attracts iron.
Round end push rod：Inhaling between iron and gas tank nozzle, inhaling iron and attracted to apply gas tank nozzle by round end push rod by electrode
Pressure.
Inhalator jar fixed mechanism：Keep gas tank position.
Elastic contact blade is with contacting ring (bilateral)：Eliminate the interference that cable scratches power.
Bearing：Fulcrum as lever.
Mass：Both ends are made to keep balance.
Lever：Two end devices (measurement assembly and test suite) are connected, balance shows that numeral is need to be changed by lever ratio
Calculate gas tank loss quality.
Taper is blunt nosed：The measurement end of lever is arranged on, and is withstood on balance, has quality damage in the inhalator jar of test lead
After mistake, taper is blunt nosed to press to balance.
Balance：The change of gas tank quality is recorded in course of injection, to control power supply to stop injection, finally weighs gas tank
Quality after injection.
Electrically-controlled component：Including dc source and power-supply controller of electric.
Elevating lever：Adjusting apparatus height.
Base：Fixed whole device.
The present invention is by electrically-controlled component control electric current, and cable is scratched power and is eliminated in the presence of elastic contact blade and contact ring,
Magnet coil, which is powered, produces electromagnetic attracting force suction iron, inhales after iron is attracted by magnet coil (electromagnet) by round end push rod to gas
Mist tank nozzle presses, and inhalator jar ejects liquid and gas in inhalator jar after being under pressure from nozzle, now inhalator jar
Clamped by inhalator jar fixed mechanism will not be because being influenceed eject position by round end push rod pressure.Liquid is jetted in aerosol gas tank
After body and gas, the quality of test suite side is lightened, and the quality of measurement assembly side is unchanged, and taper is blunt nosed to be pushed, in day
Put down after showing numerical value, passing ratio lever converses gas tank loss quality, after reaching predetermined value, cuts off jet drive button machine
The connection of structure and power supply, electromagnetic force are disappeared, and back-moving spring will inhale iron and reset, and inhalator jar stops injection, and experimental test is completed.
Compared with prior art, the invention has the advantages that：
(1) sensitive, the amplification by multiplying lever to power is responded, makes the response of balance increase, improves spirit
Sensitivity.
(2) measurement is accurate：By ratio lever, balance weight mechanism, inhalator jar fixed mechanism, bearing, jet drive button mechanism,
Elastic contact blade can effectively eliminate cable when being powered to electromagnet and scratch the interference such as power with contacting ring group into the transmission system of a set of power
Measure factor, aerosol container bodies lost weight is set accurately and timely to be delivered on balance, after avoiding manual quality's estimation and injection
It is artificial to weigh test error caused by quality, the perfect requirement to testing standard operation.
(3) balanced using counterweight, the less balance of range ability can be used, substantially reduce cost, be such as not added with counterweight, need to make
With the balance of thousands of gram quantity journeys, after setting up counterweight, the balance of small amount journey (two hectograms or so range) can be used.
