Description

The present invention relates to veterinary medicine, specifically to devices and devices for dispersing aerosol cans indoors when treating them and animals without the presence of a person in a hazardous area.

According to the patent of the Russian Federation No. 2174051 (1), a device is known having an eccentric on the gear type shaft of the electric motor, periodically lifting the can up through the pusher, where its valve head is in contact with the clamping screw, there is a bevel gear at the end of the drive shaft interacting with the bowl for the can and rotating it around the axis, while the aerosol leaves the can willow only when the valve head is pressed against the clamping screw.

The purpose of the invention is the creation of a self-contained device that maximally disperses aerosol spray cans in the air of an enclosed space.

This goal is achieved by the fact that the device is equipped with an autonomous source of electricity and a control panel for its operation, the geared motor is reversible, and a gear is located on its shaft, which is in constant engagement with two gears of half circles carrying disks for spray cans and having the ability to turn up to 180 ° towards first to each other in one, and then in the opposite direction, the upper part of the shaft carries a bearing with a pillar, on top of which the core of the electromagnet solenoid is attached, equipped with the first bracket and the contactors, the apparatus is provided with a latch with a second electromagnet which serves for fixing the first core of the electromagnet in the upper position and engagement with contactor head cartridges.

The device is schematically depicted in the drawings: in Fig. 1 is a side view, in Fig. 2 is a sectional view A-A, in Fig. 3 is a fixture fixing the device in the upper position, but its latch is inoperative, in Fig. 4 the latch is depicted in the operating position.

The device has a housing 1. It contains a reversible gear type electric motor 2 with a shaft 3, a remote control 4 for controlling the operation of the device, compartments 5 for autonomous sources of electricity (battery, batteries, etc.). The shaft 3 of the electric motor 2 in the middle part of the height carries the gear 6.

The lower parts of the axles are fixed on the upper part of the housing 1, bearings 8 are located on their upper parts 7, and a device 9 is located on it, which changes the direction of rotation of the shaft 3 of the electric motor 2 to the opposite of the original (previous) one.

On bearings 8, fixtures having halves 10 and 11 are fixed, the first having 180 ° gears 12 that are constantly engaged with the gear 6 of the shaft 3 of the electric motor 2, the device 9 has contacts 13 interacting with the arms 14 of the semicircles 10.

Semicircles 10 and 11 carry disks with limiters 15 cartridges 16 with heads 17 valves.

The upper part of the shaft 3 carries a bearing 18 with a stand 19, the core 20 of an electromagnet solenoid 21, equipped with a bracket 22 and contactors 23, is attached to it at the top. On the side (Figs. 3 and 4) of the upper part of the stand 19 there is a slot 24 for placing the front part in it a latch 25 having a screen 26, a compression spring 27, an electromagnet solenoid 28.

Device operation

Bracket 22, the device is attached to the ceiling in the middle of the room, cartridges 16 are placed on the disks between the stops 15, so that the heads 17 of their valves are under the contactors 23, placed in the compartments 5 of the housing 1 autonomous sources of electricity, the remote control 4 set the program of the device.

At a given time, the remote control 4 turns on the electric power source, the electric current enters the electric motor 2, the solenoids 21 and 28 of the electromagnets. After that, the shaft 3 of the electric motor 2 starts to rotate together with the gear 6. It begins to shift in the bearings 8 in the opposite directions of the axis 7 and the gear 12 of the semicircles 10 and 11. Together with them, the cans 16 begin to move around the piles of the vertical axes, but the rack 19 remains stationary, since the rotation of the shaft 3 of the electric motor 2 is extinguished by the bearing 18.

At the same time, the solenoid 21 attracts the core 20. The entire lower part of the device moves upward, the heads 17 of the cans 16 begin to interact with the contactors 23, their valves open, the aerosol comes out and is scattered by the rotating cans 16 along the air horizon up to 360 °. At this time, the latch 25, under the influence of the compression spring 27, is displaced and its front part falls into the slot 24 of the rack 19. At the same time, it fixes the core 20 in the upper position and shuts off the flow of electric current from an autonomous source of electricity to the solenoids 21 and 28; motor operation 2.

When the semicircles 10 and 11 are moved in opposite directions, the shoulder 14 interacts with the contactor 13 of the device 9 and switches the rotation of the shaft 3 of the electric motor 2 to the previous one. Thus, an aerosol of two cans is scattered in the air of a closed room up to 360 ° by a non-rotating device.

At a given time, the control panel supplies an electric current to the electromagnet solenoid 28 (Figs. 3, 4), it attracts the screen 26 of the latch 25 to itself. It overcomes the force of the compression spring 27, its front part comes out of the slot 24 of the rack 19, the entire lower part of the device is lowered down, the heads 17 of the cans 16 cease to interact with the contactors 23, the valves are closed, the exit of the aerosol into the air of the enclosed space is stopped.

At this time, the operation control panel 4 ensures the cessation of the supply of electricity from autonomous sources to the electric motor 2, the rotation of its shaft 3, gear 6 is stopped, the device stops working until the control panel 4 is turned back on again at a predetermined time.

We believe that the proposed device will find application in farms for the following main indications: a) does not have wires that can short circuit and create a fire hazard situation; b) does not need to receive electricity from outside; c) uniformly and universally disperses the aerosol into the air of the entire enclosed space, maintains its therapeutic concentration during the entire treatment despite the constant absorption of it by animals with inhaled air.
