Problems solved by technology

However, the existing liquid atomization devices generally have the following problems: the sprayed droplets (fog droplets) are not uniform in size, and larger droplets will directly drop to cause pollution and waste, and often fail to reach Sufficiently small droplets; especially when this liquid atomization device is used in animal inhalation exposure tests, larger droplets will drop directly on the animal and enter the animal through the skin instead of from the animal's respiratory system Into its body, the effect of inhalation poisoning that does not reach the expected target will directly affect the accuracy of the test results
Apparently, this device has the disadvantages of the existing jet liquid atomization device as described above.

Embodiment Construction

[0014] Referring to the accompanying drawings, the liquid atomization device of the present invention mainly consists of a liquid reservoir 1, a catheter 2, a liquid regulating valve 8, a nozzle 3, an air compression pump 5, a compressed air conduit 4 and a large nozzle located in front of the spout of the nozzle. The mist collection cup 6 and the large mist return pipe 7 connected to the lower part of the collection cup constitute. The large mist collection cup is usually made into a funnel shape, and its lower part is connected with the large mist return pipe. The other end of the large mist return pipe can be connected to the liquid reservoir 1, and the collected large mist liquid is introduced into the liquid storage. Recycle. It is preferable to be provided with a deflector 61 at the place directly in front of the nozzle spout 31 in the large mist collection cup 6, and the center of the deflector is preferably made into a raised cone, so that the liquid mist ejected from ...

Abstract

The invention discloses a liquid atomized device and usage as suction toxicant exposure device, which comprises the following parts: accumulator, catheter, liquid adjustment valve, sprayer, air compression pump and air compressor conduit, wherein the big droplet collection cup is set in front of sprayer, whose bottom connects the big droplet reflux pipe to build a specific liquid foggy environment; the spray sensor can be set in the spray chamber, which accomplishes the self-control of liquid foggy quantity through connecting the signal amplifier with adjustment valve controller. The invention can be an experimental device to test animal suction toxicant exposure or other exposures, which collects large droplet in the accumulator to circulate.

Description

technical field [0001] The invention relates to a liquid atomizing device for atomizing liquid through a spraying method and its application as a poisoning device for inhaling poisoning of animals or exposing other objects. technical background [0002] The device for atomizing liquid by spraying has the advantages of simple structure, convenient operation and low cost. However, the existing liquid atomization devices generally have the following problems: the sprayed droplets (fog droplets) are not uniform in size, and larger droplets will directly drop to cause pollution and waste, and often fail to reach Sufficiently small droplets; especially when this liquid atomization device is used in animal inhalation exposure tests, larger droplets will drop directly on the animal and enter the animal through the skin instead of from the animal's respiratory system Entering its body, the effect of inhalation poisoning that does not reach the expected target will directly affect th...
