Description

TECHNICAL FIELD The present invention relates to a hypochlorous acid water spraying device that performs sterilization and deodorization with weakly acidic hypochlorous acid water for improving the indoor environment in agricultural facilities such as greenhouses.

Conventionally, it has been used to sterilize the surface of hatching eggs of chickens and the like by atomization of weakly acidic hypochlorous acid water. Hypochlorous acid water is an aqueous solution containing hypochlorous acid (HClO) obtained by electrolyzing an aqueous solution of hydrochloric acid or sodium chloride as a main component. In addition, a method of sterilizing and disinfecting the interior of a room by spraying a chemical agent such as a bactericide has been performed. Weakly acidic hypochlorous acid water is remarkably effective against bacteria, viruses, and germs in greenhouses, and has almost no effect on the human body.

For example, as disclosed in Patent Document 1, a container of weakly acidic hypochlorous acid water, a mixing spray device and a liquid tube are connected, and a compressor and a mixing spray device are connected with an air tube, A mixing spray device holder is provided on the front of the blower, and the weakly acidic hypochlorous acid water stored in the container is operated by the compressor at an air pressure range of 0.2 MPa to 0.5 MPa, and the liquid and air A spray sterilization device for preventing the spread of viral infection is provided, which sprays from a mixing spray device via a tube for spraying particles having a size of 7 to 10 μm.

However, the conventional method using a sterilizing agent as described above does not always have sufficient sterilizing power, so a large amount of sterilizing agent must be sprayed, and because it is sprayed with large droplets of water, It was very difficult to sterilize in use. By the way, the particle diameter of sprayed from a spray bottle that can be used easily is about 10 to 20 micrometers, which is large, so it falls down before it flies far.

Therefore, in recent years, a method has been attempted in which a sterilizing aqueous solution is atomized into fine particles by ultrasonic waves or the like and released. For example, as disclosed in Patent Document 2, by discharging fine particles of hypochlorous acid aqueous solution over a wide range, it is possible to sterilize and eliminate bacteria in a wide range of indoor atmospheric air with a small amount of hypochlorous acid aqueous solution. A sterilization method and a sterilization device using a hypochlorous acid aqueous solution are provided.

Ultrasonic waves are applied to the hypochlorous acid aqueous solution in the hypochlorous acid aqueous solution storage section supplied from the supply tank by an ultrasonic oscillator, and microparticles of the hypochlorous acid aqueous solution are generated in the microparticle generation section. , the fine particles are discharged into the atmosphere from the spray nozzle through the induction conduit. At this time, the spray is conveyed far and discharged on a carrier flow sent out from an injection port provided directly below the spray port.

However, in the case of Patent Document 2 described above, the entire apparatus is a desktop type, and the amount of hypochlorous acid water that can be stored from the supply tank to the reservoir is limited. it is not possible to disperse

Moreover, in the case of Patent Document 2 described above, since the ultrasonic diaphragm is attached with bolts to the inner bottom (bottom) of the reservoir, when the water depth of the hypochlorous acid aqueous solution in the reservoir is large, Since the length to the ultrasonic diaphragm at the bottom is long, it is difficult to efficiently generate fine particles from the water surface.

In addition, in the case of Patent Document 2, the whole apparatus is of a stationary type and not of a mobile type, so it is difficult to transport the apparatus in a large-area room in an agricultural facility such as a greenhouse.

Therefore, the present invention was created in view of the conventional circumstances as described above. In the hypochlorous acid water spraying device that performs the above, even if it is a large-capacity water tank container that can secure a capacity that can be sprayed over a wide area in a large-area vinyl house, ultrafine particles of hypochlorous acid water are efficiently generated. To provide a jig hypochlorous acid water spraying device capable of spraying a large amount of hypochlorous acid water over a wide area over a long period of time and facilitating transportation in a room with a wide area.

In order to solve the above-mentioned problems, in the hypochlorous acid water spraying device according to the present invention, the hypochlorous acid water in the water tank container storing the hypochlorous acid water is super finely divided by ultrasonic vibration. A hypochlorous acid water spraying device that sterilizes and deodorizes an indoor atmosphere including a vinyl house by atomizing and spraying through a nozzle, wherein a tray container is placed in the hypochlorous acid water of the water tank container. An ultrasonic oscillator for driving the ultrasonic oscillator of the ultrafine atomization generator is immersed and floated in the water tank container. is equipped, and when the surface of the ultrasonic transducer is immersed in hypochlorous acid water, the power of the ultrasonic oscillator is turned on, and the surface of the ultrasonic transducer is tilted by the inclination of the water tank container. The ultrafine atomization generator is provided with a water level sensor for turning off the power of the ultrasonic oscillator when the hypochlorous acid water runs out, and the ultrasonic oscillator has an electrostrictive sensor inside the ultrasonic oscillator. The ceramic vibrating element of the mold is fixed, and an opening is formed in the center of each side wall surface of the ultrafine atomization generator, so that the hypochlorous acid water can enter the tray container from the four side directions. The fine atomization generator is characterized by maintaining a floating state at a predetermined depth position .

The water tank container is characterized by having a volume enough to secure at least a spraying capacity in the vinyl house, and being movable by means of a frame with a handle provided with wheels such as casters and tires.

The nozzle is formed by a flexible bellows-shaped cylindrical member attached to the opening of the top surface of the water tank container, and the hypochlorous acid water sprayed from the nozzle is super finely atomized on its back. It is characterized by having a blower for diffusing into the room.

According to the present invention, for example, in a hypochlorous acid water spraying device that performs sterilization and deodorization with weakly acidic hypochlorous acid water for improving the indoor environment in agricultural facilities such as vinyl houses, in a large area vinyl house Even with a large-capacity aquarium container that can secure a capacity that can be sprayed over a wide area, hypochlorous acid water ultrafine particles can be generated efficiently, and a large amount of water can be sprayed over a wide area for a long time. It is possible to provide a jig hypochlorous acid water spraying device that can be easily transported in a room with a large area.

That is, the present invention uses ultrasonic vibration to superfinely atomize hypochlorous acid water in a water tank container storing hypochlorous acid water, and sprays it through a nozzle to improve the atmosphere of a room including a vinyl house. A hypochlorous acid water spraying device for sterilization and deodorization, wherein an ultrafine atomization generator is formed by disposing an ultrasonic vibrator on the bottom of a tray container in the hypochlorous acid water of the water tank container. Because it is immersed and floated, even if the water depth of the hypochlorous acid water is large due to the large-capacity water tank container, the ultra-fine atomization generator that floats just below the water surface produces hypochlorous acid water of about 4 to 5 micrometers. It can be efficiently generated from the surface of the water in the form of ultrafine particles, and in this way, the ultrafine mist of hypochlorous acid water that adopts the ultrasonic method spreads to every corner of the indoor space, and efficiently produces a fog that is not hot. and can be gently sprayed.

In addition, the sprayed mist disappears immediately, but the ingredients do not fall down, so they can ride the wind far away and spread to every corner of the room to disinfect the air, and hypochlorous acid water is safe. Since it is made from ingredients, inhaling the atomized mist will not affect your health.

Furthermore, since the ultra-fine atomization generator itself is not directly attached to the water tank container and is floating in the hypochlorous acid water, even if forced rigid body vibration acts on the water tank container from the outside, This vibration is not directly transmitted to the ultra-fine atomization generator itself, but is transmitted while being buffered and protected by fluid hypochlorous acid water, resulting in external damage to the ultra-fine atomization generator. is not given directly. Moreover, the maintenance of the ultrafine atomization generator is also facilitated.

The water tank container is equipped with an ultrasonic oscillator for driving the ultrasonic oscillator of the ultrafine atomization generator, and when the surface of the ultrasonic oscillator is immersed in hypochlorous acid water, the ultrasonic oscillator A power on/off switch for turning on the power of the ultrasonic oscillator and turning off the power of the ultrasonic oscillator when the hypochlorous acid water on the surface of the ultrasonic oscillator disappears due to the inclination of the water tank container. Since the water level sensor is provided in the ultrafine atomization generator, even if the water tank container is tilted and there is no water on the surface of the ultrasonic oscillator of the ultrafine atomization generator, the power supply to the ultrasonic oscillator is automatically turned off. Therefore, it is possible to prevent the ultrasonic vibrator of the ultrafine atomization device from being damaged due to careless oscillation driving in anhydrous conditions.

The water tank container has a volume that can secure a volume that can be sprayed in at least one roll of the vinyl house, and is movable by a frame with a grip part equipped with wheels such as casters and tires. A large amount of ultra-fine mist can be dispersed over a wide area for a long time, and transportation in a large-area room is facilitated.

The nozzle is formed by a flexible bellows-shaped cylindrical member attached to the opening of the top surface of the water tank container, and the hypochlorous acid water sprayed from the nozzle is super finely atomized on its back. Since the blower is provided for diffusing the hypochlorous acid water into the room, even in a room with a large area, the cooperative action of the nozzle and the blower makes it possible to spread the ultra-fine mist of hypochlorous acid water over a wide area.

Reference numeral 1 shown in the drawing is weakly acidic hypochlorous acid water for improving the indoor environment in agricultural facilities such as greenhouses. It is a hypochlorous acid water spraying device that performs sterilization and deodorization by 9.

As shown in FIGS. 1 and 2, the hypochlorous acid water spraying device 1 has an upper portion that can be opened by a lid portion 2a, and a predetermined amount of hypochlorous acid water 9, which will be described later, can be stored inside (cooler ) A box-type water tank container 2 and an ultrasonic oscillator 3 with a power supply for exciting and driving an ultrasonic oscillator 4a of an ultrafine atomization generator 4, which will be described later, have wheels 5a such as casters and tires at the four corners of the lower surface. It is equipped with a vertical U-shaped frame-shaped grip part 5b and is mounted on a frame 5 which is erected at the end so that it can be moved.

In FIG. 2, two nozzles 6 are arranged side by side. Further, on the outside of the water tank container 2, an ultrasonic oscillator 3 with a power source (for example, a battery with an AC adapter (not shown)) for driving the ultrasonic oscillator 4a of the ultrafine atomization generator 4 is provided. It is

As shown in FIGS. 3 to 5, in the hypochlorous acid water 9 contained in the water tank container 2, a plurality of (12 total in the figure) ultrasonic transducers 4a are placed on the bottom surface of the tray container. A plurality of ultrafine atomization generators 4 (two in the figure) are immersed and floated. An electrostrictive type (Langevin type vibrator) ceramic vibrating element (piezo element) that expands and contracts when an electric field is applied, for example, is fixed inside the ultrasonic vibrator 4a. An externally attached ultrasonic oscillator 3 is electrically connected to the electrodes of each of these ultrafine atomization generators 4 via, for example, a cable 4b with an alligator plug.

In addition, an opening 4c is formed in the center of each of the four side walls of the ultrafine atomization generator 4 (tray container), and the hypochlorous acid water 9 enters (introduces) into the tray container from four sides. It is possible. As a result, the ultra-fine atomization generator 4 is maintained in a floating state at a predetermined depth (for example, just above the water surface or at a depth of several centimeters) (see FIG. 5).

The ceramic vibrating element converts the high-frequency power emitted by the ultrasonic oscillator 3 into mechanical vibration, generates powerful ultrasonic waves from the ultrasonic oscillator 4a, and generates ultrafine particles of about 4 to 5 micrometers of the hypochlorous acid water 9. is generated from the surface of the hypochlorous acid water 9 and sprayed from the nozzle 6 to the outside. 2, 3 and 5, reference numeral 10 denotes a stirring fan for stirring ultrafine particles of the hypochlorous acid water 9 generated inside the water tank container 2.

Also, if the dilution factor of the stock solution with a concentration of 200 PPM is 4 times, the concentration is 50 PPM, the stock solution is 5.0 L, and the water is 15.0 L, the concentration of the hypochlorous acid water 9 is relatively suitable. In addition, although the amount of sprayed per one vinyl greenhouse is preferably 10 L for 2 hours, the present invention is not limited to this. For example, for 2 vinyl greenhouses, spraying is carried out for 3 to 4 hours, and for concentrations of 50 PPM to 65 PPM, spraying is carried out for 2 to 3 hours.

Next, an example of the use and operation of the form configured as described above will be described. , the electrodes of the individual ultrafine atomization generators 4 are electrically connected to the externally attached ultrasonic oscillator 3 via, for example, a cable 4b with an alligator plug.
