Implementation of the utility model.

In the proposed embodiment, the air hood for masters of eyelash extension consists of a split body 1 (see Fig. 1, 2) of rectangular cross-section made of the front and rear parts with two symmetrically made through holes 2 located at the right and left edges of the body 1 Inside the holes 2 on the mounting platforms 3 are mounted electric fans 4, the blades of which are oriented in such a way that when they rotate, the air flow is directed inside the holes from the front side of the case to its rear part. In this case, the distance between the fan blades 4 is from 3 to 6 cm.To turn on and off the electric fans 4, a switch 5 is mounted on the front side of the housing 1, and to power them in the housing 1, on its rear part, a connector 6 is mounted.

On the back of the body, rectangular plates 7 are horizontally mounted. In this case, the installation of the plates 7 is made with the possibility of changing their inclination relative to the vertical, and their width is guaranteed to cover at least 1/2 of the area of the holes 2. In the upper part of the body 1, an element is mounted on its lateral surface mounts 8 for installing the device in working position.

In one of the configuration options, the hood may additionally contain a hinged multi-link bracket 9 (see Fig. 3) containing several pairs of profile guides 10 mounted by a movably detachable connection between paired connecting plates 11. At one end of the bracket 9, a counterpart of the fastening element 8 of the hood is made, and at the other end, the bracket 9 contains a clamp 12 for attaching it to the edge of the working surface.

The air extract for eyelash extension masters is used as follows.

Before starting work (see Fig. 4), the bracket 9 is fixed with a clamp 12 on the edge of the working surface. The fastening elements 8 are combined with its counterpart on the bracket 9 and the hood is placed at the level of the master's face. Select the required angle of inclination of the plates 7 to direct the air flow upward. Connect the power cable to connector 6 and switch 5 to supply voltage to electric fans 4. By rotating the blades of fans 4, air with material vapors is drawn into holes 2 and directed upward using plates 7.

The specified technical result of the utility model, the prevention of the deposition of vapors of harmful substances on the surface of the case in its middle part is achieved by reducing the distance between the fan blades 4. At the same time, the distance from 3 to 6 cm significantly improves the air exhaust in the space in front of the middle part of the device, which with one side prevents the deposition of vapors of harmful substances on the surface of the case in its middle part, and also increases the efficiency of air extraction in the space in front of the middle part of the device, in which the face of the eyelash extension master is mainly located, and thereby prevents it from inhaling harmful vapors.

Preventing the deposition of vapors of harmful substances on the surface of the body allows to increase the structural reliability of the product by eliminating the degradation of the surface of the body of the device under the action of vapors.

Reducing the distance between the blades of the fans 4 is achieved, depending on the version of the hood, in different ways.

In one embodiment (see Fig. 5), the distance between the blades of the fans 4 is reduced by displacing the fans 4 towards the center of the hood without changing the position of the holes 2. In this case, the main force of the intake air flow falls on the center of the hood where the zone with the highest concentration is located vapors, and in areas with a lower concentration of vapors falling to the edges of the hood, the force of the air flow is weaker.

In another embodiment (see Fig. 6), a decrease in the distance between the blades of fans 4 is achieved by installing fans 4 of a larger diameter without changing the size and position of the cutouts 2. This increases the efficiency of air flow suction due to an increase in the volume of sucked air, compared to the prototype, since in the prototype, with the given geometric parameters of the holes 2, the installation of fans 4 of a larger diameter is impossible, since their diameter is limited by the distance between them.

In the next embodiment (see Fig. 7), the reduction in the distance between the blades of the fans 4 is achieved by displacing the holes 2 towards the center of the hood. In this case, the main force of the intake air flow falls on the center of the hood, where the zone with the highest concentration of vapors is located, and in the zones with a lower concentration of vapors falling to the edges of the hood, the force of the air flow is weaker.

Let us consider an example of achieving the technical result using the example of the implementation of the claimed solution shown in Fig. five.

Before carrying out cosmetic procedures for eyelash extension, the device is brought to its original position, an example of which is shown in Fig. 4, then during cosmetic procedures from the glue used for eyelash extension, for example, cyanoacrylate, vertical streams of harmful vapors are formed, mainly in the area in front of the middle part of the device, which, rising to the device, are sucked in by fans 4, while no deposition of vapors of harmful substances occurs on the surface of the case in its middle part, and the efficiency of air extraction in the space in front of the middle part of the device, in which the face of the eyelash extension master is predominantly located, significantly the concentration of glue vapors near the master's respiratory tract is reduced.

In 2020, the applicant made a mock-up of the claimed device, the trial operation of which made it possible to achieve the claimed technical result.
