Description

Yo

The invention relates to means for spraying liquid media in the form of aerosols and mists on various surfaces in the art, as well as drugs in medicine.

The aim of the invention is to provide the possibility of optimal supply of liquid medium to the working end of the concentrator, reducing its losses in use and simplifying operation.

Figure 1 shows a device for ultrasonic atomization of a liquid medium; figure 2 is a section along aa in figure 1; in Fig.3 is a view along arrow B in Fig.1; in Fig.4 is a side view in Fig.Z.

A device for ultrasonic atomization of a liquid medium comprises a housing 1 with a support sleeve 2, an ultrasonic emitter 3 with a hub 4 having a transformer 5 working end, forming a magnetostrictor mounted on rubber supports 6 and 7 in the housing 1.

The device is also equipped with a container 8 with a threaded cover 9. a lock nut 10 and an outlet opening 11 for supplying a liquid medium to the outer surface of the concentrator 4.

In addition, the device is equipped with a threaded neck 12, rigidly connected to the container 8 and mounted with the possibility of axial movement relative to the support sleeve, and secured to the cover 9 by a locking needle 13 for closing and adjusting the outlet 11 of the container 8, which is made in the form of a nozzle. A hole 14 is made in front of the hole 11, forming a two-stage system with the hole 11. Cover 9 is made with

refueling funnel 15. and the working end face of the hub 4 is inclined to its axis by the value of the cross section of droplets dk and faces the outlet 11 of the container 8.

At the working end of the concentrator 4, a cascade of drain channels is made (Fig. 4). Capacity 8 is installed with the possibility of removal and replacement.

A device for ultrasonic atomization of a liquid medium operates as follows.

After connecting the ultrasonic emitter 3 to an ultrasound generator (not shown), for example of the URSK type, with an operating frequency of 25.5 kHz through a transformer 5, ultrasonic vibrations are excited at the working end of the concentrator 4. At the same time, by lifting the locking needle 13, a liquid droplet feed is provided through hole 11 ™ on the inclined surface of the working end. The liquid medium, falling down the cascade of gutters, is briefly held onto them, dispersed and sprayed. The locking needle 13 controls the dropping frequency and the length of the spray pattern.

An example of a specific embodiment of the invention is an operating device with a capacity of 5 cm3 shown on a scale of M1: 1 in Fig. 1, where: the neck 12 has a thread M 12x1, the hole 14 is of a diameter of 2 mm, the hole 11 is a diameter of 0.7 mm; the outlet end is made in the form of a truncated cone with an angle of 30 °, a height of 3 mm and a diameter of a smaller base 1.7 mm, the needle 13 has a length of 28 mm, a diameter of 3 mm, a cone of 60 °, a 4-diameter concentrator of 11 mm. dk 3-4 mm, the gutter is a radius of 10 mm, the maximum depth along the generatrix is 1 mm (see figure 4). The device is equipped with replaceable containers 8 with a volume of 5 and 10 cm, the metered filling of which is carried out with a syringe. If necessary, the container 8 can be connected via a hole to the filling funnel 15 with a hose to a more capacious vessel with a liquid medium (not shown).

The device for ultrasonic atomization of a liquid medium in comparison with the base object allows: to provide an optimal supply of a liquid medium to the working end of the concentrator; reduce its spray losses; to simplify the operation of the device due to the lack of piping and increased structural rigidity.
