Description

FIELD OF THE INVENTION

The present invention relates to an energy- and fluid-saving 'swirl control' that produces an adjustable cone and droplet spray. It can thus be used in a variety of spraying techniques which are well suited to agriculture and industry and are suitable for home cleaning and sanitation techniques.

The object of the present state of the art is the controllable atomization technique of the invention and its application. Another object is to provide a nebulizer structure suitable for cleaning and sanitary purposes.

The nebulizer structure of the present invention is also known and used with respect to the main elements (flutter elements, vortex chamber, closure needle). On the one hand, the relevant literature shows this; for example: Fejes-Tarján Chemical Machinery and Operations (Textbook Publisher 1972); Oliver Fűzi, Flow Engineering and Water Machines, and Hugó Frensidu Sanitertechnik, Campus Publisher 2001. The same can be said from the patent literature, except that they do not include certain specific embodiments of the elements in the shower, for example, and / or solutions. The same picture is presented to us, for example, by a plethora of objects in the plumbing industry, and by industry, too. In the construction industry spraying equipment is used for whitewashing and painting walls, but at the present state of the art the corrosion protection painting of some large metal tanks and metal equipment can also be well solved by spraying equipment.

Reviewing patents and information on the subject matter, we can determine that spray shower structures "have long been used in military technology and may have been treated as a military secret and not patented." For example, the Soviet-Russian personalization car, which used six-position spray shower structures. so there was no civilian use. This solution is based on verbal information.

Among the shower structures are Japanese patents, which are also protected in the US, such as US5344 080, Kazuhiro Machui (Tokyo) and Thosio Tagaki (US) 4909443, where the inventor's main purpose is to regulate water-saving energy. , quite complex structural solutions, but these have not finally appeared on the world market. The subject patent uses a mandrel to close the outlet, but this is not analogous to its own patent because this invention does not create an artificial vortex. That is, the Japanese invention is not a spray and the use of a mandrel forms a kind of needle valve.

Reference should also be made to the German patent DE 198 13 366-A1, which is intended to use a nozzle for creating a spray droplet for showering and other purposes. The objective is very good, but the structure described is not functional because it does not produce an artificial vortex and without it the structure is inoperable! It is not enough to designate a structural element as a turbulence chamber if no vortex is produced. This patent describes a peculiar, i.e. non-existent, process in which the atomized fluid particles are provided with an air bubble. This hypothesis does not work either because of the surface tension described in the Hungarian Eötvös Law in the physical literature. Liquid does not contain detergent as one of the main elements of a bubble toy used by children. This patent does not appear on the EU and world markets either. U.S. Patent No. 742,725 discloses a two-head shower structure, wherein a rotary pump uses a paddle wheel as a flow element for closing and opening the water flow, which results in a pulsating jet of water, but does not control spraying or turbulence. The pulsating jet of water is expected to save water and energy.

It can be stated that these patents do not use atomization, that is, they do not have a spin element and do not control the vortex.

The phenomenon of spontaneous dispersion

Some and high-pressure cleaning devices (in car and carwash systems) are spontaneously sprayed, which is related to the fact that swirls can be produced during the machining of the structures and spontaneously atomize at the outlets. However, this is not a deliberate and unpatentable, but a consequence of a technical error.

It is another object of the present invention to achieve a very significant reduction in water and fresh water use by controlled spraying for cleaning and cleaning purposes. Earth's water and fresh water resources are relatively decreasing due to the ever-increasing water use of populations of more than 6 billion people, resulting in a lack of fresh water in some geographical areas. Accordingly, the patent is intended to illustrate the operation of the shower structure.

Object of the invention

The spraying of liquids, water and its control, and the use of a jet of liquids for cleaning purposes, and for purposes which are known in the art to use the jet. According to the literature and experience, an artificial vortex should be created for the spraying of liquids and this vortex should be released at its base. The flow chart for this process is illustrated in FIG. 2-1, where the tangential introduction provides for the creation and removal of the artificial vortex through the orifice. This figure also illustrates a solution of control, which can be called external control, because the vortex chamber is divided, where the fluid is tangentially introduced in the upper part to create the vortex, and the vortex chamber has a threaded connection and also includes a nozzle orifice. This solution is used by many people, agriculture2

GB 227 323 Β1, using the adjustable nozzle for garden spraying on tall trees. In practice, in the vortex chamber, the artificial vortex extends from the nozzle orifice to the upper part of the chamber. The control can be solved by adjusting the height of the resulting vortex by an external thread. If the height of the vortex chamber is small, the resulting atomized beam will have a large cone angle and the atomized particles will be smaller. As the chamber height is increased by thread, the atomization cone angle becomes small and the diameter of the particles increases.

The characteristic of the vortex is that the pressure inside the vortex is almost 0, i.e. the vapor pressure of the fluid at a given temperature. On this basis, water and other jet pumps operate.

The inside of a vortex is referred to in the literature as an air core or vortex hole, which may be capable of sucking in a secondary liquid or gas.

The main object of the invention

Instead of changing the height of the vortex chamber from outside the nozzle, we adjust the height of the vortex from the inside.

Another object of the invention

For cleaning purposes, use water and water sprayed for sanitary purposes, as not only will you retain a great deal of comfort, but will also significantly reduce the amount of water and energy required for warm-up. Because if the use of water is reduced, the amount of energy needed for heating will also decrease. Experimental equipment achieved a savings of about 75%.

Atomised water particles have long been used in personal cleaning and chemical de-radiation, but they have only been used in military technology, not in civilian practice, and may not have been introduced into civilian practice through "military secrets" and thus filed by government patent offices. system was not invented. Advances in sanitary engineering have created hand-held shower enclosures made of metal or plastic, which are connected to the hot water system by flexible connecting pipes providing hot water.

There was also a major energy crisis and a lack of fresh water in the world. This justifies the development of new sanitary and other cleaning products, bearing in mind that other techniques used in industry as well as in agriculture also have the benefit of non-infinitely adjustable spray control.

Control of the atomized liquid jet by varying the size of the vortex hole "the air core".

Liquids have developed a wide variety of control devices to control the amount of flowing water in modern hydro-engineering. An excellent example of this can be seen in the literature, for example the work of Olivér Fűzi: Flow Engineering Machines and Systems (Tankönyvkiadó Bp. 1991); The chapter on water turbines on page 382 describes the regulator needle, which is designed to control the speed of the turbines. This device, and its flow-oriented, streamlined design of the needle, is also capable of controlling the size of the vortex hole and air core, taking into account aspects of similarity theory and multidimensional size reduction. When this device is movably incorporated into the atomization chamber, it is also suitable for controlling the atomized liquid, the water jet particles and the spray cone. The insertion allows the flow needle to be adjustable to produce either a constant spray or infinitely adjustable, or even to close the nozzle orifice in the extreme position. The installation allows the flow needle to be adjustable to produce a constant spray, or the choice of a mounting where the vortex hole is infinitely adjustable or, in the extreme, also suitable for closing. In a special design, i.e. drilling the flow needle along its length, it also allows the introduction of secondary fluid. The flow needle can also be integrated with flip-flops and a spring for operation. The control is made possible by different flow needle designs in various spraying devices, which sometimes need to be designed with a streamline design so that the overflow of liquid and water is not reduced.

The object of the present invention is thus to provide a general purpose atomiser as defined in claim 1. Preferred embodiments of the nebulizer are shown in Figures 2-8. claims.

In Figure 1, Figure 1 illustrates a hand shower structure and this special design generally illustrates the atomizer structures, since a similar flow needle is required for any atomization, since the same is to use a stone element, a vortex chamber and an orifice. By rotating the nozzle 12 in Figure 1, the holes 12b are exposed and thus function as a conventional multi-jet shower head. When sealed, seal 16 is provided to the vortex chamber 11b

Fig. 4 is a view of Figs. 4 and 5, where Fig. 4 employs a variant wherein the size of the vortex hole is controlled by unscrewing and unscrewing the closure cover 4-2 externally, and the arcuate wheel variant 43b (Fig. 3b). ).

Figure 5 illustrates a spiral leaf spring 5-1 which can function as a leaf spring and a spiral flutter at the same time.

Since one of the goals of controlled spray technology is the patented development of water and energy saving cleaning and shower devices, mechanical cleaning may also be required. Thus, an obvious solution is to adapt a brush disk to the controlled atomizer, which can be moved by moving the surface to enhance the cleaning effect. Alternatively, when used in the shower structure, a massaging vasculature on the body surface becomes possible and dead skin cells can be removed more easily from the skin surface.

Control of water volume and pressure

It is an object of the present invention to use a spray liquid or a water jet for cleaning and showering. This means very significant water savings, so if you don't have a water volume and pressure control tap installed in your network, you may need to control your network independent water volume and pressure for a spray shower. One solution is to incorporate a control valve in a cleaning or shower structure that structurally mimics the butterfly valves. Butterfly valves are commonly used in AHUs, but the current state of the art allows them to be used with flowing fluids.

The father of flow technology, Euler, made measurements with a circular disc, which allows a butterfly valve to be adapted to a nozzle. That is, if the disc is parallel to the flow of the fluid, it will barely narrow the cross-section and thus not provide substantial flow resistance. If the butterfly valve is perpendicular to the flow direction, liquid or water may flow through a small hole. Thus, the amount and pressure of water can be controlled, thereby controlling the strength of the atomized jet.

The purpose of the drawings is to illustrate the conceptual design of general and special atomized controlled structures, wherein the numerals are at the same time reference numerals.

The atomization and flare elements shown in these figures can be designed in mass production to be interchangeable. Thus, when used as a scrubber in a replacement, we can replace the more appropriate equipment in the scrubbing technique.

Note that in the above nebulizers and spraying devices, the elimination of shortcomings of conventional nebulizers by internal control of the vortex and the multi-purpose

EN 227 323 Β1 allows significant fluid and water savings. This objective is mainly that the vortex is controlled not from the outside, but mainly from the inside, and that the physical properties of the vortex are whirled. This is mainly made possible by the specially designed needle. A further difference is that the affected area can be adapted to absorb spray additives compared to the state of the art. In addition, the use of a brush disk allows for a better cleaning effect or a massage technique for shower structures.

Description of the Function of the Nozzle for a Cleaning or Shower Device According to the state of the art, the nozzle devices are available in four versions and combinations thereof. These are described in Section 2.1. The tangentially introduced vortex chamber of FIG. directional and 2.3. Impact nozzles marked in Figure 2.4. The rotor auger inserts utilizing the torque insertion of FIG. 1A can be made into an adjustable liquid pressure nebulizer by controlling the swirl space itself with the elements (regulating needle) of the present invention. This is preferably done by passing the fluid through the hole in the ergonomically designed hand grip into the vortex chamber. Thus, a suitably designed regulating needle controls both the length of the vortex chamber and the vortex itself by means of an established spring mechanism. The needle can be adjusted with the help of an ergonomically designed (accessible) angle lifter. Alternatively, fixing the spray cone and droplet size to the correct position can stabilize the process. The particular design of the control needle according to the present invention should be experimentally tested, with due consideration of hydrodynamic considerations and design, to facilitate the formation of a turbulent vortex. Accordingly, the adjusting needle; the hydrodynamic resistance of the flow body shall be low and suitable for closing the orifice in the extreme position. It is very important to ensure the smoothness of the flow body so that no local vortexes are formed, either on the wall of the vortex chamber or on the surface of the needle. Experiments in this regard show that the optimum design of the control needle is a rotational body that approximates the shape of a drop of free-flowing liquid.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS and General Purpose Nozzle Operation Nozzle devices always meet a particular need, and therefore, a special atomization device is described by describing the operation of a 'spray hand shower'. This is also necessary because the different atomization devices are extremely ergonomically different. This is necessary to fit well with the use and the hands of the person and the health aspects of the person performing the application (eg face shield, protective clothing, spraying fruit trees).

However, in order to function properly, the design must always include:

- an excuse Stone Element

- a vortex chamber

- an external or internal solution controlling the length of the vortex hole

- an orifice.

Their operation is analogous in all equipment. This means creating a vortex with a nozzle opening at its base. The length of the vortex, which extends from the nozzle orifice to the back wall of the chamber, can be controlled externally or internally. External control means that the vortex chamber is divided in design and the threaded connection is twisted in and out to control the length of the vortex chamber. The internal control, on the other hand, introduces a flow-compatible needle into the vortex chamber, which penetrates into the vortex hole and is thus continuously adjustable from the outside. This adjusts the length of the vortex and the spray cone. Accordingly, the operation of the hand shower system is as follows:

The structure is illustrated in Figure 1 of Sheet 1. The spray hand shower is connected to the fluid network and pressurized either through a tap or a butterfly valve. As a result, the shower swirl chamber is filled with water or other liquids. By actuating the angle lever 15, the control needle 13b is moved away from the nozzle closing position against the pre-tension spring 14 and consequently the water on the actuator 13, variations of which are shown in Fig. 3, curved, angled blade wheel or screw , the water enters into a vortex and exits through the nozzle opening 12a in the form of a cone in the form of droplets. In addition to creating a vortex, the swirling element 13 also has the function of guiding the control needle 13b in the swirling chamber 11c. This will prevent harmful eddies and vibrations from forming on the wall of the control needle or swirl chamber. The angle lifter 15 is secured to the fluid inlet pipe 11a firmly but pivotally. The fluid inlet pipe 11a and the nail lift 15 are ergonomically adapted to the human hand. It just depends on design techniques. The angle lever 15 can be locked in desired positions by the guide 15c and the fastener 15d, and the operation can be locked either continuously or in steps.

The movement of the nose 15 on the arc is converted by the axis 13 into a linear motion, and therefore an oval opening is formed on the nose 15 to provide the required play. The adjusting screw 15b ensures that the regulating needle 13b closes the nozzle opening 12a in its initial position. Plot the length of the spring 14 to determine the amount of base preload. During operation, the spring 14 is tensioned on the rear wall of the chamber 11b and the actuator 13a, and when the nail 15 is released, the regulating needle 13b closes the nozzle opening 12a. The resulting vortex can be controlled by the needle 13b which reduces it

EN 227 323 Β1 increases the length of the vortex. In the vortex chamber, the spray liquid cone is formed and the "air core" is formed, the vortex hole 12 in the vortex chamber formed by the chamber 11b and exiting the nozzle orifice to decompose the vortex droplets. It forms a cone of atomized droplets. The sealing of the chamber housing 11b and the shaft 13 is provided by the ring 0 17. By rotating the cap 12, the holes 12b can be released to operate the unit as a conventional hand shower.

Of course, if the cap is screwed back in, the seal will close the holes and the structure will only work again by spraying. The size of the air core or vortex hole determines the atomization cone, i.e. the relative position of the control needle 13b and the atomization opening 12a. This means that the control needle 13b and the nozzle opening 12a are close to each other, resulting in a diffused liquid spray with a larger taper angle and smaller droplets, which results in a very comfortable feeling of comfort.

If the position of the control needle 13b and the nozzle opening 12a are larger relative to one another, a smaller cone angle and larger particles are formed, and the atomized beam is harder and the feeling of comfort is reduced. At the same time, when cleaning objects, it is advisable to wash with a softer, large tapered spray, while the dirt and detergents can be effectively removed with a harder jet. The pressure in the structure is controlled by the network valves or is determined by the position of the butterfly valve 19c.

Higher pressures result in a smaller spray cone, while lower pressures (around two bars) result in a softer wide taper spray. The butterfly valve 19c bore 19 is closed, the pressure is reduced and a soft jet is created. If the butterfly valve is open, it will produce more pressure and a harder beam, which is indicated by the size of the taper. The two positions of the butterfly valve 19 may be adjusted by the shaft 19a, which may be secured by the stops 19d. The shaft 19 is sealed by the ring 19b 0.

Preferred examples of use, variants

1. A 2.5. Figure 1B illustrates a removable closure cover which may also be adapted to the spray device of Figure 1. It can be either concave or convex and can be fitted with a brush disc. Due to its mechanical effect, it is ideal for cleaning equipment (kitchen sink, car wash, or shower structures).

2. In 3d. Fig. 11A shows a preferred variation of the control needle 13b, wherein the tip of the control needle is wedge-shaped, which is capable of closing a wedge-shaped spray slot. This variant can be used for garden watering devices or cleaning devices.

3. Through-hole adjustment needle (Sheet III, Fig. 3e). Its use is justified if a secondary liquid is to be introduced into the vortex. The vortex pressure is less than the atmospheric pressure and acts like a water jet pump. In the vortex, the primary and secondary fluids mix well and can be sprayed together. If no secondary fluid is to be aspirated, use the 3e4 end cap to seal the rear opening of the nebulizer needle.

4. Figure 4 illustrates an externally controlled simplified nebulizer structure that ultimately controls the size of the vortex hole by rotating the top of the split vortex chamber. Liquid or water is introduced through the inlet port 4.1a through the inlet port 4.1a to the chamber 41 with a tangential inlet which already has a swivel, but the swing member 4.3b can further assist in the formation of the vortex. The dispersion is created by adjusting the size of the vortex chamber with the lid 42. Therefore, in the simplified solution, the control needle can be fixed, but the point is to control the size of the vortex.

5. Figure 5 illustrates an atomizing device having a spring 5.1 formed as a helical leaf spring, thereby serving as a fluttering element at the same time as the spring function.

Advantages of the patented solutions

The main advantages of the patented nebulizer devices are summarized as follows:

- A single orifice structure can be used to produce a hard or soft jet that is adjustable by controlling the atomization cone and particle size, that is, the vortex.

- During spraying the medium droplet diameter and the spraying cone can be adjusted.
