Abstract

The invention relates to aerosol production devices and can be used in everyday life and technology. The aim of the invention is to improve the usability. For this, the container is made in the form of a bellows, at the bottom end of which a threaded sleeve is fixed on the inner surface for engagement with a thread made on the outer surface of the cap, and a siphon tube is installed in the cap cover with the possibility of axial displacement and fixing it in the extreme positions x When the bellows is stretched, it is filled with liquid, and when compressed, a working pressure is created for atomization. 4 il.

Description

The invention relates to aerosol production devices and can be used in everyday life and technology.

The purpose of the invention is to increase the ease of use

Fig. 1 shows the nebulizer at the end of filling it with liquid and air, a section; in fig. 2 - the same, working position, section; in fig. 3 - the upper part of the sprayer at the moment of filling the container with liquid; in fig. 4 - the same, at the moment of filling the tank with air.

The atomizer contains a container 1 with a cap 2 installed in its upper part with a spray head 3 and a valve 4 and a siphon tube 5 communicating with the spray head 3. The container 1 is made in the form of a bellows, at the bottom end 6 of which the sleeve 7 is threadedly fixed 8 on the inner surface to interact with the thread 9. made on the outer surface of the cap 2. In the cap of the cap 2 there is a threaded bore 10, in which axially displace and fix in the extreme positions is set a background tube 5 having threaded extensions 11 and 12 in its upper and lower part. The siphon tube 5 is provided with thumbstuffs 13. In the spray head 3, a nozzle 14 and a stem 15 are formed.

The spray liquid works as follows

To fill the container 1 with the working fluid, the siphon tube with the spray head 3 removed is extended and fixed in the extreme extended position with the help of the thumb 13 (Fig. 3), after which the end of the tube 5 is lowered into the main working fluid vessel and the bellows is expanded by the cap 2 and sleeve 7. The discharge created in the bellows ensures that the liquid enters it from the main vessel. For a more convenient filling of the spray bottle, a hose may be attached to the end of the siphon tube 5. Control of the degree of filling of the container 1 with the liquid is carried out visually by dividing the main vessel or by the level of the liquid in the bellows (in the case of

tea is made of a transparent material, e.g. polyethylene).

After the dispenser is filled with the working fluid, the siphon tube 5 is moved to an intermediate position (Fig. 4) and the bellows is fully stretched. Next, the siphon tube 5 is moved and fixed (Fig. 1).

To bring the sprayer into working field, those with and / / bellows, combining the cylinder 2 and the sleeve I and turning their friend

relative to each other, the last ones are entered in a winter. The final compression of the bellows and the creation of a working pressure in it (1 ... 2 atm) does not require significant muscular effort due to the use of a threaded transmission between the cap 2 and the sleeve 7.

After creating the required working pressure in the bellows, the spray head 3 is installed on the siphon tube 5 (Fig. 2). The device is ready for operation.

To carry out the work, the nozzle 14 is directed to the desired direction and the spray head 3 is pressed, the stem 15 of which then rests against the ball of the valve 4 and opens the latter, ensuring that the working fluid under pressure flows from the tank 1 to the spray head 3.

The implementation of a fluid dispenser with a capacity in the form of a compressible bellows and a retractable siphon tube simplifies and reduces the cost of construction, enhances ease of operation due to the syringe filling method of the container with liquid and using a screw gear to create pressure in the container.

The proposed design is most suitable for sprayers with a small working volume, such as inhalers.
