R. Korea, z. No. KR2020060026937, 29.09.2006, publ. 12/18/2006). The invention relates to a device for atomizing air or a mixture of air and water, the main body having an air channel through which air passes, and a water channel communicating with the air channel for supplying water and a nozzle for injecting air and mixture passing through the air channel. A water inlet valve is installed on the water passage to open and close the water passage.

Accordingly, it is possible to atomize only air, or selectively atomize a mixture of water and air, and create a portable air atomizing device that can be carried and used in a portable manner.

The disadvantages of the invention also include the need to supply compressed air from a compressor or portable cylinder. There is no possibility of supplying liquid under pressure in the system, but only compressed air with mixing of washing liquid from the container.

Additionally, a common disadvantage of all three considered prototypes is the inability to supply washer fluid to the pressure line under high pressure to a height of tens of meters.

The systems and devices disclosed in the prior art do not provide a solution to a number of technical problems, in particular, the creation of a device for cleaning, including optical, surfaces, having a simple and technological design, which allows the operator to effectively clean surfaces from contamination, with the supply of liquid high pressure media, which reduces the flow rate of the treatment fluid, and can also be used in areas where there are special requirements, incl. for explosion safety.

The technical problem is solved as follows. The present invention proposes a device for cleaning optical surfaces, comprising a housing with a working member configured to accommodate liquid and / or gaseous media, equipped with inlets for liquid and / or gaseous media, channels for moving liquid and / or gaseous media and means for supplying liquid and / or gaseous media to the external environment. The device is additionally characterized in that the working body provides a portioned supply to the means providing the supply of liquid and / or gaseous media to the external environment, a liquid medium, and the gaseous medium enters the means providing the supply of liquid and / or gaseous media to the external environment, from the reservoir connected to the body through the gaseous medium inlet.

The features common to the analogue are the presence of a housing containing a working member made with the possibility of accommodating liquid and / or gaseous media, equipped with inlets for liquid and / or gaseous media, channels for moving liquid and / or gaseous media and means for supplying liquid and / or gaseous media to the environment.

The features that distinguish the device from the analogue are the provision of a portioned supply by the working element to the means providing the supply of liquid and / or gaseous media to the external environment, a liquid medium, and the supply of a gaseous medium to the means providing the supply of liquid and / or gaseous media to the external environment, from a source connected to the housing through a gaseous medium inlet.

In the first particular case, the device is characterized in that the working body contains a chamber equipped with a piston with the ability to move inside the chamber space and dividing it into compartments in such a way that at least one of the compartments communicates with the container for the gaseous medium, and the other with a container for a liquid medium.

In the second particular case, the device is additionally characterized in that the piston through the rod is additionally equipped with a handle made in such a way that in one of the positions it helps to close at least one of the channels for the gaseous medium.

In the third particular case, the device is characterized in that the means for supplying liquid and / or gaseous media to the external environment, associated with the channels for moving the liquid and / or gaseous media, provide alternating atomization of the liquid and gaseous media.

In the fourth particular case, the device is characterized in that it is equipped with a trigger, the actuation of which causes the flow from the container from the gaseous medium to the gaseous medium inlet of the housing.

In the first refinement of this particular case, the device differs in that it contains several sets of channels for a gaseous medium, arranged in such a way that one of the sets of channels ensures the flow of the gaseous medium into the chamber compartment, and the other set provides the supply of the gaseous medium to the means for spraying liquid and / or gaseous media to the environment.

In the fifth special case, a device, characterized in that the flow of liquid medium into the corresponding compartment of the chamber is provided by extending the handle of the rod connected to the piston.

In the sixth particular case, a device characterized in that it is equipped with a container with a liquid medium and a container with a gaseous medium, and in the container with a gaseous medium, the gaseous medium is under pressure above atmospheric.

In the seventh particular case, the device is characterized in that when the piston is moved to a position in which essentially the entire space of the chamber is occupied by a gaseous medium, by closing the channels, a gaseous medium is supplied to the means for spraying liquid and / or gaseous media into the external Wednesday.

In the eighth particular case, the device is characterized in that the means for supplying liquid and / or gaseous media to the external environment additionally comprise means for connecting to a pressure line, which is equipped with an object containing an optical surface.

The device is a gun form factor purifier. The working body of the device is designed in such a way that it allows placing a liquid and gaseous medium isolated from each other in its internal space. Channels for the movement of liquid and / or gaseous media are a means of supplying liquid and / or gas between the units of the device: from the inlet to the working body and further to the means providing the supply of liquid and / or gaseous media to the external environment, as well as ensuring the delivery of a gaseous medium from the corresponding entrance directly to the means providing the supply of a liquid and / or gaseous medium to the external environment, bypassing the working body. The portioned supply of liquid to the means providing the supply of liquid and / or gaseous media to the external environment is provided by the return movement of the piston, which displaces the liquid medium from the corresponding compartment of the working body chamber. The movement of the piston when the liquid medium is displaced is provided due to the flow of the gaseous medium into another compartment of the working body chamber. The entry of the gaseous medium is provided from a reservoir in which the gaseous medium is preferably under pressure. An alternative to a pressure vessel can be a pressure line. One of the main characteristics of the gaseous medium is that the gaseous medium entering the inlet of the casing is supplied at a pressure higher than atmospheric pressure.

The design of the chamber of the working body makes it possible to carry out, by moving the piston, a collection of a liquid medium into the corresponding compartment by creating a vacuum in the compartment. In the extreme position of the piston, with the rod fully extended, essentially the entire space of the chamber is a compartment filled with a liquid medium. Then, by means of a system of valves, upon activation by the operator of the trigger mechanism, the supply of a gaseous medium from a corresponding source to another compartment of the chamber is initiated. As a result, there is a reverse movement of the piston and the displacement of the liquid medium through the channel to the means providing the supply of the liquid and / or gaseous medium to the external medium.

The design of the rod handle is made in such a way that when a liquid medium is displaced by a gaseous medium and the piston is moved to the opposite position from the initial one, the handle by pressing action closes the channel that ensures the flow of the gaseous medium into the corresponding compartment of the working body chamber, which changes the path through which the gaseous medium flows, causing the flow of the latter directly to the means by means of providing the supply of liquid and / or gaseous media to the external environment. Thus, at the first stage, the cleaning and wetting of the surface to be cleaned with a portioned volume of liquid is provided, and then the air flow provides drying of the surface to be cleaned from liquid droplets.

The device is equipped with a trigger mechanism implemented on the principle of a pistol trigger. Pressing the hook by the operator causes the gaseous medium from the appropriate source to flow into the fluid compartment.

As described in the description below, the device contains a set of channels that allow the supply of liquid and gaseous media to the chamber of the working member and to the means for supplying liquid and / or gaseous media to the external environment. These channel sets allow the device to perform its function without the need for complex hydraulic or electrical systems. The cycle of operation of the device is provided by the mechanical movement of the piston, carried out by the operator and the force of the gaseous medium under pressure, which displaces the liquid medium from the compartment of the working body chamber, and also carries out the final stage of the cleaning cycle: drying the surface to be cleaned. Thus, the sets of channels provide communication of a gaseous medium with one of the compartments of the working body chamber, as well as with means for supplying a liquid and / or gaseous medium to the external environment, i.e., essentially to the surface to be cleaned.

As already noted above, the intake of a liquid medium from the source occurs mechanically by extending the rod connected to the piston by the corresponding handle. The vacuum created in the formed compartment of the working body chamber allows the liquid to flow through the corresponding channels into the corresponding compartment. Then, the actuation of another system of valves, as well as the entry of a gaseous medium into another compartment of the chamber, causes the ejection of liquid onto the surface to be cleaned. This design makes it possible, without the use of complex technical means, to achieve effective cleaning of the optical surface, while simultaneously saving liquid, since the dispensing is carried out in portions.

The device is equipped with a source of a gaseous medium made in the form of a container or a duct connected, in turn, with a source of a gaseous medium. Since the gaseous medium for the purposes of the present technical solution must be at a pressure above atmospheric to displace the liquid medium from the corresponding compartment of the working body chamber, either a container with a pressure inside it, or a device for injecting the gaseous medium, essentially in the form of a compressor, is required.

To understand the principles of operation and features of various implementations of the invention, the following is a description of the figures of the technical solution. Although the text of the description explains in detail the preferred embodiments of the technical solution, it should be understood that other embodiments of the invention are possible. Accordingly, there is no need to limit the scope of legal protection of a technical solution exclusively to the presented implementations and lists of subsystems, assemblies and components. The invention can be implemented in other ways. At the same time, when describing the preferred options for technical solutions, for clarity of understanding the basic principles of the invention by a specialist, it is necessary to clarify the terms used in the description.

It should be noted that the units and parts of the device used in the singular in the description and the claims also represent plural forms, unless the opposite is explicitly stated. For example, referring to a component of a device also means referring to a collection (plurality) of such items.

Also, specific terms are used in describing the preferred embodiments for clarity of understanding. The term is intended to be used in the broadest sense in which it can be interpreted by those skilled in the art and includes all technical equivalents used in the same manner and for the same purpose. So, in particular, the term "optical surface" means a certain solid surface of a substantially optically transparent material, in at least one segment from the optical range. Such a surface can be the glass of a video camera of a video surveillance system or another surface that requires periodic cleaning from contamination. The term "liquid medium / gaseous medium" means a substance used in a device, which is, respectively, in a liquid and gaseous state of aggregation. It can be air or an air mixture for a gaseous medium and water or a cleaning agent or a mixture thereof for a liquid medium. In the description, the equivalent terms "liquid" and "gas" can also be found. The term "channel" refers to the components of the device (housing), which provides the flow of gaseous and / or liquid medium between the inlet, the working member and the means for supplying the gaseous and / or liquid medium to the external environment. The form of execution of the channels within the framework of this technical solution is not fundamental. In the case of the present invention, the phrase "means for supplying liquid and / or gaseous media to the external environment" is used to describe the ejection component of the device responsible for supplying liquid or gas to the external environment, including to the surface to be cleaned. The component can be made in the form of nozzles. In the description of the present technical solution, the equivalent term "spray means" is also used. The phrase "portioned supply" means that in one cycle of operation of the device an amount of substance enters the external environment from the working body, approximately equal to the volume of the compartment of the working body chamber. The term "source" in relation to sources of liquid and / or gas means that the device is connected or contains directly connected to it a container or compressor in relation to a gaseous medium, supplying to the inlet of the housing of the device liquid and gas, respectively. The implementation of such a source can be technically solved in another way. The term "chamber" means a substantially closed container provided with a piston and inlets for liquid and / or gaseous media. Moreover, the chamber is equipped with an outlet for a liquid medium, which can be either combined with an inlet for a liquid medium, as in the general case of implementation, or be made separately. The chamber, in accordance with the invention, is divided into compartments of variable volume formed by a movable piston driven by a handle with a rod. The term "handle" can refer essentially to the shape of the piston rod tip. The name is given for the convenience of identifying the component of the device. The handle or rod tip is designed in such a way that the operator can extend the rod with the piston beyond it. The phrase "alternating spraying" characterizes the operation of the device, namely the order of supply of liquid and gas to the spray means.

The words "consisting", "containing", "including" mean that at least the specified component, element, part or step of the method is present in the composition, object or method, but does not exclude the presence of other components, materials, parts, steps of the method, even if such a component, material, part, method step performs the same function as the specified one.

The materials from which the various elements of the present invention are made, indicated below in the description of examples of a specific embodiment of the device, are typical, but not required for use. The materials indicated in the present examples of execution can be replaced by numerous analogs that perform the same function as the examples of materials given in the description.

Let's turn to the attached figures. In accordance with one of the private implementations of the present invention, the device is intended for cleaning from dirt, preferably optical (translucent) surfaces. As shown in FIG. 1, 3, the device is a spray gun 1 made in the form factor of a pistol, consisting of a body 2 equipped with a working body containing a chamber in the form of a working cylinder 3, in which a piston 4 moves, connected to a rod 5 with a tip (handle) 6. Channels 7 in the body are used to move liquid and gas in the space of the body. The liquid flows are regulated by check valves 8. For the flow of gas into the corresponding compartment of the chamber 3, the valve, combined with the trigger 9, opens, when pressed, the tract for the entry from the container with compressed air 10 opens. all the liquid from chamber 3 opens the air valve 11, causing gas to flow through the check valve 12 to the atomizing means 13. The liquid for cleaning is in the container 14.

The device works as follows. The operator pulls the rod 5 out of the chamber 3 by the tip 6. A vacuum is formed behind the piston 4, due to which the washer fluid is sucked from the reservoir 14 into the chamber 3. The volume of the collected washer fluid is determined by the length of the extended rod 5. By pressing the trigger 9 of the pistol grip, which mechanically is connected to the valve, air from the container 10 through the opened valve enters the corresponding compartment of the chamber 3, pressing on the piston 4. The piston 4 moves, squeezing the collected portion of the washer fluid from the chamber 3 onto the atomizing means 13. After returning the piston 4 to its original position, when squeezing out of all liquid, the air pressure valve 11 opens, due to the shape of the tip 6 of the rod 5. The operator continues to hold the trigger 9, while the compressed air from the container 10 and through the opened valve 12 through the atomizing means 13 is supplied to the external environment. There is a blowing of the surface to be cleaned from drops of washing liquid. Also, the device can be equipped with an outlet pipe made with the ability to connect to the pressure line of the camera's washing system.

An implementation of the technical solution disclosed in FIG. 2, in which containers with compressed air 10 and liquid 14 are in a backpack worn by the operator.

The embodiments of the present invention are not limited to the above specific examples. Other forms of implementation of the technical solution can be proposed without departing from the meaning of the invention.

The above examples of execution are given in order to show the industrial applicability of the device and to give a general impression of the device. The scope of legal protection of a technical solution is determined by the claims, and not by the description presented, and all changes made using equivalent features fall under the legal protection of the present invention.
