Description

Nozzles for spraying < RTI ID = 0.0 >

The present invention relates to a nozzle for spraying, and more particularly to a spray nozzle for atomizing a solution into fine particles in air to jet an object or space into the object.

The nozzle is a tube mounted at the end of the flow path for ejecting the solution at a high speed, and is largely divided into a contraction type and an expansion type. Such a nozzle utilizes the fact that the pressure energy is converted into the velocity energy when the jetting cross-sectional area is reduced when the high-pressure liquid is jetted. That is, the shrinking type narrows the cross-sectional area of the flow path and injects the solution in the shape of a stem, and the expanding type spreads the cross-sectional area of the flow path to spray the solution in the form of mist.

The shrink type is used for supplying a solution to a target or for dropping off an attached material, and an expandable type is used for coating a solution on a surface of a target in the form of a thin film or for extracting or supplying a solution into fine particles. Here, unlike the contraction type, the expandable type can be regarded as having a different quality and range of application depending on the size of the particles atomized in air. That is, in recent years, a method of making the particles of the solution to be sprayed into nano (nm) has been sought.

For example, Korean Registered Utility Model No. 20-0277184 entitled " Fine particle spraying device for basic cosmetics "and Korean Patent Registration No. 10-1063469" Solution jetting body and nano ion spraying device using the same " The disclosures of the present invention increase the efficacy of the solution while improving the permeability by spraying the particles of the solution with nanoscale.

However, the disclosed documents have a problem in that the amount of particles that are actually nanoized and sprayed to the outside is remarkably low as a result of nano-deposition of particles simply colliding with the resist ribs or nano plates. That is, when the sprayed particles collide with the nanoparticles, many particles are deposited on the surface rather than particles that are repelled from the surface and are nanoized. Therefore, there is a case where the amount to be sprayed is inevitably applied only to a specific use not related to it.

Korean Registered Utility Model No. 20-0277184 entitled "Spraying device for fine particles of basic cosmetics" Korean Patent Registration No. 10-1063469 "Solution Injector and Nano Ion Spraying Apparatus Using the Same"

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a spray nozzle for atomizing a solution into fine particles in air and spraying the spray nozzle. The nozzle is mainly composed of a housing tube (10), a spray tube (20) and a grinding means. The nozzle of the present invention is portable, and is suitable for industrial or medical use in which a solution containing a plurality of components is automatically pumped and used, rather than for home use where pumped water is manually pumped. That is, as the particles of the solution to be sprayed become finer, the effect of the solution is amplified, or the spraying or spraying quality is improved.

The housing tube 10 according to the present invention is formed into a tubular shape having a center at one end as shown in FIGS. 1 to 3, and is mounted to one or more crushing motors 31 described later. The housing tube 10 is provided with a connection port 11 through which the solution fed from the outside flows into the outer surface and a flow passage 15 communicating with the connection port 11 to discharge the solution to the inner surface. Here, a fixing plate 12 is integrally formed on one side of the outer surface on which the connection port 11 is located, for guiding the removal and mounting of the connection body 11 with other bodies. That is, the fixing plate 12 is formed with a plurality of fixing holes for guiding mounting to a hand gun or a robot arm.

At this time, the inner surface of the housing tube 10 includes a branch groove 13 for transferring the solution introduced from the connection port 11 to the injection tube 20 as shown in Figs. 2 and 3, The mounting groove 14 is formed so as to be stepped inward. That is, when one end of the spray tube 20 is inserted into the mounting groove 14, the branch groove 13 is automatically closed from the outside as shown in FIG. The solution flowing into the inlet 11 is collected in the branch groove 13 through the flow path 15 and the solution collected in the branch groove 13 is delivered to the injection tube 20 in a constant positive pressure. Here, one surface of the housing tube 10, which is engaged with one surface of the spray tube 20, is further formed with a packing groove 10a into which a packing for preventing leakage of the solution collected in the branch groove 13 is inserted.

1 to 3, the spray tube 20 according to the present invention is formed in a tubular shape having a center and is mounted on one surface concentric with the housing tube 10. The spray tube 20 is integrally formed with the airtight plate 22 and the airtight tube 23 which are in tight contact with the one surface of the housing tube 10 and the mounting groove 14 to seal the branch groove 13 from the outside, And at least one atomizing nozzle 21 is detached and mounted on the airtight plate 22 opposed to the branch groove 13.

Here, the airtight plate 22 is formed vertically inward on one side of the spray tube 20, and the airtight tube 23 is formed horizontally inside the airtight plate 22 in a direction concentric with the spray tube 20 . The airtight plate 22 and the airtight tube 23 may be formed independently of each other so as to be mounted on the spray tube 20. The airtight plate 22 and the airtight tube 23 may be integrally formed As shown in FIG. That is, the solution collected in the branch groove 13 closed by the airtight plate 22 and the airtight tube 23 is simultaneously delivered to the plurality of spray nozzles 21 at a constant positive pressure. At this time, the airtight plate 22 is formed with a plurality of mounting holes 22a for guiding the housing tube 10 to be fastened to the housing tube 10. The airtight plate 13 is also provided with the branch grooves 13 on the outer surface of the airtight tube 13, And a packing groove 13a into which a packing for preventing leakage of the solution introduced into the packing groove 13a is further formed.

The pulverizing means according to the present invention is a pulverizing means for pulverizing the solution sprayed into the pulverizing tube 20 into fine particles as shown in Figs. 1 to 3, (31), and a crushing blade (35) connected to the crushing motor (31) to crush the sprayed solution into fine particles.

The crushing motor 31 is mounted so as to be exposed in the center of the spray pipe 20 in the housing pipe 10. The pulverizing motor 31 is preferably a high-frequency type rotating at 10,000 RPM or more to rotate the pulverizing blade 35 at a high speed. The spindle 32, which rotates at the center of the crushing motor 31, can be optionally provided with either a single shaft or a double shaft type. That is, in the double shaft type, the crushing blade 35 can be mounted on one shaft and the other shaft, respectively. In this case, it is possible to construct a pair of spray tubes 20 by only one crush motor 31. [

The crushing blade 35 is connected to the spindle 32 protruding into the spray pipe 20 and rotates at a high speed. Here, the crushing blade 35 rotates in the direction of accelerating the ejection of the solution sprayed from the spraying nozzle 21. That is, the particles of the solution in which the crushing blade 35 rotating at high speed is sprayed are crushed into nano-sized fine particles. The pulverized fine particles are accelerated again by the pulverizing blades 35 and are ejected to the outside.

Hereinafter, the flow and action of the solution will be described with reference to FIG. 4 based on an embodiment in which a solution is coated on the surface of the object to a predetermined thickness. First, a solution (coating agent) to be coated on the object is prepared, and the prepared solution is manually or automatically pumped and fed to the connection port 11. The pressurized solution is gathered in the state of being filled in the branch groove 13 through the flow path 15 and is sprayed from the spray nozzle 21. [ The solution ejected from the spray nozzle 21 is sprayed in the form of atomized mist in the air. Subsequently, the particles of the solution sprayed with the pulverizing blade 35 rotating at high speed are pulverized into nano-sized fine particles and accelerated and coated onto the object surface. Therefore, since the particles of the solution are sprayed in a nano-sized atomized state, it is possible to coat the surface with uniform and uniform thickness, thereby improving the quality.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
