Description

The invention relates to medical equipment and can be used in aerosol generators for vaccination and therapy of animals, as well as for disinfection of premises.

By main auto F 528 096 ⁵ iz news elektroaeroeolny sprayer, which has a housing, a gas and liquid nozzle formed by the inner and outer screw-on nozzles, and inducing electrode. For ¹⁰ separate control of aerosol dispersion, the part of the induction electrode located in the nozzles is made with a variable cross section p}. ^fifteen

However, when using the well-known electroaerosol dispenser, liquid fluid condenses in its channels, which, through the nozzles of the molester, enters the sprayed substance, changes its concentration, and violates the vaccination regime.

The purpose of the invention is to prevent dilution of the sprayed substance with condensate of moist air.

The goal is achieved by the fact that two chambers are made in the casing of the electroaerosol sprayer, placed one on top of the other, one chamber having a hole for ejecting condensate and connected to the channel of the inducing electrode using labyrinth channels, and the chamber located in the first is filled with a filtering element and with a face the side is connected to the air inlet fitting, and holes for filtered air and condensate are made in its cylindrical wall.

The drawing shows an electroaerosion rasp.pylitel, section.

The sprayer contains a housing 1 made of an insulating material with a central channel for screwing in the induction electrode 2.

The internal assembly z. 854402 4 is screwed on the casing 4, the cone of which is tapered fist of which, on,. screwed onto the cylindrical part, forms a gas nozzle * The density is ensured by a gasket. 4, clamped by a ring 5. An outer nozzle 6 is screwed onto the inner nozzle 3 ₅ , forming a fluid nozzle coaxial with the gas nozzle and induction electrode 2. The head 7 of the induction electrode is made in the form of a truncated cone screwed into the end face of the cylindrical part of the electrode. It with nozzles 3 and 6 forms cracks 8 and 9, respectively. The composite design of the internal nozzle 3 and the inducing electrode 15 15 allows you to conveniently change the sizes of the slits 8 and 9 and thereby obtain the required spray performance. Inside the induction electrode 10 is a channel ₂₀ for supplying pressurized air, which through openings 11 enters the gas nozzle. To supply voltage to the induction electrode, a bolt 12 with a contact is screwed into the housing 1. To supply 25 fluid to the fluid nozzle there is a fitting 13 with a contact 14 for grounding.

A glass 15 is screwed onto the housing 1, forming a chamber 16. At the bottom of the glass there is a fitting 17 for supplying compressed air. In the chamber 16 is a cylinder 18, divided by a transverse wall 19 into two parts. One part forms a chamber 20, filled with a filter element 21, which is pressed by a mesh 22. The chamber 20 communicates with the chamber 16 with openings 23 for air passage and openings 24 for passage of the flowing liquid. The other side of the wall 19 passes into the tube, by means of which the cylinder 18 is attached to the 'housing 1. In addition, this wall together with the side wall of the cylinder and the nozzle 25 of the corresponding shape forms labyrinth channels 26, through which the camera 16 through the holes 27 is connected to the channel induction electrode. To remove condensate, the chamber 16 communicates with the environment through a channel 28 into which a screw 29 is screwed, containing a calibrated hole 30.

The electroaerosol atomizer operates as follows.

Compressed air through the nozzle 17 enters the mesh 22 and through it to the filter element 21. Various particles are trapped in the chamber 20, and condensate flows through the openings 24 into the chamber 16 and through the channel 28, and the hole 30 of the bolt 29 is thrown out under pressure. At the same time, air seeps through the filter element 21 and, passing through the mesh 22 and the holes 23 of the cylinder 18, enters the channel between the outer wall of the cylinder 18 and the inner wall of the glass 15. Then, through the labyrinth channels 26 and openings 27, the air passes into the channel 10 induction electrode. At the same time, the air changes its direction several times, as a result of which condensate particles are extracted from the air stream, collected in the chamber 16 and removed through the channel 28 and the calibrated hole 29. Thus, the cleaned air enters through the openings 11 to the slots 8 and 9 of the hens 3 and 6 which, passing through these slots, creates a vacuum in them, due to which the liquid entering through the nozzle 13 is sucked into the expansion zone. When voltage is applied to the induction electrode 2 through the contact of the bolt 12, the spray particles acquire a charge that is negative to the field voltage source 14 is grounded through the contact.

Cleaning compressed air immediately before it enters the gas nozzle according to this invention · avoids disruption due to clogging of the nozzle outlet openings, and, moreover, the vaccination mode is not violated by diluting the substance with the condensed moist air.

Due to the fact that the established immunization regimen is not violated, the overall time spent on work is reduced and the usability of the aerosol dispenser is increased.

The invention relates to medical technology and can be used in aerosol generators for vaccination and therapy of animals, as well as Up disinfection facilities. According to the main auth. By 528096 lime, there is an electroaerosol sprayer in which there is a body, a gas and a liquid nozzle, formed by internal and external screwing in 1 nozzles, and an inductive electrode. In order to regulate dispersion separately, the aerosol located in the nozzles of the part of the inducing electrode is made with a variable cross section fl}. However, when using a well-known electro-aerosol dispenser, its bone condenses in its channels, which through the nozzles disperses the substance into the sprayed substance, changes its concentration, and thus disrupts the vaccination regimen. The purpose of the invention is to prevent the dispersion of the sprayed substance by condensation of moist air. The goal is achieved by having two chambers placed one inside the other in the case of an electroaerosol sprayer, one chamber having an opening for draining condensate and connected to the duct with an arc 0 (its electrode using labyrinth channels, and the chamber located in the first one is filled with a filter and on the front side it is connected to a fitting for air, and in the cylindrical wall it has holes for filtered air and condensate.
