Description

Wide-angle spray head

Technical Field

The invention relates to the technical field of high-pressure mist making spray heads, in particular to a wide-angle spray head.

Background

The spray head is applied to environmental cooling, plant preservation in the market, visual effect application, agricultural production, irrigation, fishery, cultivation, food processing, industrial cleaning and the like for fogging. The atomizing is used for refining water molecules, so that the fine water molecules at least achieve the effects of environmental cooling, market plant preservation, visual effect application, agricultural production, irrigation, fishery, cultivation, food processing, industrial cleaning and the like. The atomizing at least comprises: ultrasonic mist generation, rotary centrifugal mist generation and high-pressure mist generation.

Ultrasonic atomization is performed by using ultrasonic waves, titanium alloy or static electricity to vibrate water into water mist with a diameter of 1 to 5 μm, and then the water mist is sprayed out by a fan and a nozzle, wherein the spraying is performed in the following steps: air heat exchange, efficient fire extinguishing, room humidification and purification, hospital ward humidification and anionization, air conditioning humidification and purification, refrigerator humidification and energy conservation, greenhouse humidification and the like, and after water mist absorbs heat, the water mist is immediately vaporized into a part of air. However, the disadvantages of ultrasonic fogging in use are: the device has extremely high requirement on the water quality required by use, so that high-cost filtering equipment is required to be used for filtering the used water, and the single-machine humidifying device has small humidifying capacity and can only be suitable for small-space and small-amount humidifying. The ultrasonic atomization has the advantages that: the atomizing particles are minimum, the heat absorption is obvious, the installation is easy, and the cost price of a single machine is low (as shown in Taiwan patent certificate No. I564054).

The rotating centrifugal mist generation generally utilizes centrifugal force to convert water into 5-10 μm ultra-fine mist droplets under the action of a rotator driven by an air compressor and a mist particle spraying device, and the mist droplets are mostly used in the following processes: fresh-keeping in the vegetable market, orchid planting and cooling and dedusting in an open space. However, rotary centrifugal fogging also has its disadvantages: the operation of the air compressor can generate great noise, and the size of the generated fog particles is not uniform enough. The rotary centrifugal mist-making has the advantages in use that: no requirement for water quality, easy installation, moderate fog-making amount, and intermediate overall manufacturing cost and selling price (as shown in taiwan patent certificate nos. M316491 and 456176).

High-pressure mist generation is carried out by driving water under 100 Kg/cm 2-200 Kg/cm2 of ultrahigh pressure and then spraying the water through an atomizing nozzle to obtain 30-60 mu m atomized water drops. Generally, the spray particles sprayed by the atomizing nozzle are large, so that the time and the required distance required for heat exchange absorption of air are long, and the spray sprayed by the atomizing nozzle is suitable for humidifying large space, and is suitable for large fields such as large gardening, poultry or beast farms, mushroom growing farms, brick kiln farms, restaurants, performance farms and the like, and has the functions of cooling, heat dissipation, dust removal and moisture preservation. Its disadvantages are complicated structure, difficult installation, high water quality requirement and high cost. The high-pressure atomizing has the advantages that: the number and the range of the nozzles in the whole field are better in expandability, the nozzles can be selected to control the size of the fog particles, and the method is suitable for large-area application. However, the high pressure atomizing nozzle cannot be adjusted in any direction and has a limited atomizing angle, so that when the nozzle needs to be used at different angles, the nozzle with a proper angle needs to be assembled, and if the atomizing water drops are finer, the driving pressure value of the ultrahigh pressure of 250 Kg/cm2 or more needs to be increased to obtain the atomizing water drops with the diameter of 18-20 μ M, which often affects the damage of the pressure value of the whole nozzle and the whole pipe, or the separation and the breakage of the pipe, and the diameter of the high pressure atomizing nozzle is very fine, so that the sprayed mist is very little, and the pressurized water is mixed and accumulated in the nozzle, therefore, the high pressure atomizing nozzle has poor efficiency (as shown in Taiwan patent No. M487777 and No. M553101). High pressure atomization is to promote atomization of atomized water droplets, and is combined with a nozzle spray by a gas mixing technique (as shown in taiwan patent document No. M548954).

However, ultrasonic atomization, rotary centrifugal atomization and high-pressure atomization are all used with their pertinence, and nozzle spray or device cannot achieve both fine atomization and wide-angle atomization, and particularly in the high-pressure atomization category, there is a problem that ultra-high pressure driving is too large, and when pressurization is required, the nozzle and the pipe are damaged due to pressure intolerance, or the pipe is detached or broken due to the pipe.

Disclosure of Invention

In view of the above, the high-pressure mist generation in the related art has the technical problem that the nozzle and the piping are damaged or broken due to the over-large ultra-high pressure driving, so the inventor of the present invention has developed in the direction of reducing the high-pressure mist generation delivery pressure and improving the effect of wide-angle mist generation.
