Description

  TECHNICAL FIELD The present invention relates to a hypochlorous acid water spraying device for sterilizing and deodorizing a weakly acidic hypochlorous acid water for improving an indoor environment in an agricultural facility such as a vinyl house.

  Conventionally, it has been used to sterilize the surface of eggs such as chickens by atomizing the spray of weakly acidic hypochlorous acid water. Hypochlorous acid water is an aqueous solution containing hypochlorous acid (HClO) as a main component, which is obtained by electrolyzing an aqueous solution of hydrochloric acid or sodium chloride. In addition, a method of spraying a chemical such as a bactericidal agent to sterilize and disinfect the interior of the room is performed. Since weakly acidic hypochlorous acid water has a remarkable effect on bacteria, viruses, and miscellaneous bacteria in a house and has almost no effect on the human body, it is widely used as most sterilizing / disinfecting agents.

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

  However, the method using the conventional sterilizing agent as described above has to disperse a large amount of sterilizing agent because the sterilizing power is not always sufficient, and since it is sprayed with water droplets of large particles, the room is usually It was very difficult to sterilize in use. By the way, since the particle diameter of the spray bottle that can be used easily is about 10 to 20 micrometers and the particles are large, it drops down before flying 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 then discharged. For example, as disclosed in Patent Document 2, by discharging fine particles of an aqueous solution of hypochlorous acid over a wide range, it is possible to sterilize and sterilize a wide range of atmospheric air in a room with a small amount of aqueous solution of hypochlorous acid. There is provided a sterilizing method and a sterilizing apparatus using the hypochlorous acid aqueous solution.

This is because the ultrasonic wave acts on the hypochlorous acid aqueous solution in the hypochlorous acid aqueous solution storage part supplied from the supply tank by the ultrasonic vibrator, and the fine particle generation part generates fine particles of the hypochlorous acid aqueous solution. The fine particles are discharged from the spray port into the atmosphere through the guide pipe. At this time, it is supposed that the spray is carried to a far distance and discharged on a carrier flow sent 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 tabletop type, and the amount of hypochlorous acid water stored in the storage unit from the supply tank is limited, so a large amount of fine particles and a wide range over a long period of time are used. It is impossible to spray on.

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

  Further, in the case of Patent Document 2 described above, since the entire apparatus is a stationary type and not a mobile type, it is difficult to convey the apparatus in a large area in an agricultural facility such as a vinyl house.

  Therefore, the present invention was created in view of the above existing circumstances, for example, deodorization with weakly acidic hypochlorous acid water for improving the indoor environment in agricultural facilities such as vinyl houses. In a hypochlorous acid water spraying device that performs, even if it is a large-capacity aquarium container that can secure a capacity that can be sprayed over a wide area in a large area vinyl house, efficiently generate ultrafine particles of hypochlorous acid water. An object of the present invention is to provide a jig hypochlorous acid water spraying device that can be sprayed in a large amount over a wide area for a long time and can be easily transported in a room having a large 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 superfine by ultrasonic vibration. A hypochlorite water spraying device for atomizing and spraying through a nozzle to sterilize and deodorize an atmosphere in a room including a vinyl house, wherein the water is contained in the hypochlorous acid water in a tray container. It is characterized in that an ultra-fine atomization generator having an ultrasonic transducer placed on the bottom surface of is immersed and suspended.

  The aquarium container is equipped with an ultrasonic oscillator that drives the ultrasonic oscillator of the ultrafine atomization generator, and the ultrasonic oscillator has a surface that is immersed in hypochlorous acid water. Turn on the power source of the ultrasonic oscillator, and turn off the power source of the ultrasonic oscillator triggered by the disappearance of hypochlorous acid water on the surface of the ultrasonic oscillator due to the inclination of the water tank container A water level sensor is provided in the ultrafine atomization generator.

  The aquarium container has a volume capable of ensuring at least one volume to be sprayed into the vinyl house, and is movable by a mount with a grip portion including wheels such as casters and tires.

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

  According to the present invention, for example, in a hypochlorous acid water spraying device for sterilizing and deodorizing a weakly acidic hypochlorous acid water for improving the indoor environment in an agricultural facility such as a vinyl house, in a wide area vinyl house Even if it is a large-capacity aquarium container that can secure a volume that can be sprayed over a wide range, it is possible to efficiently generate ultrafine particles of hypochlorous acid water, and it is possible to spray a large amount over a wide area for a long time. It is possible to provide a jig hypochlorous acid water spray device which can be easily carried in a room having a large area.

  That is, the present invention is an ultra-fine atomization of the hypochlorous acid water in the aquarium container storing the hypochlorous acid water by ultrasonic vibration, by spraying through a nozzle of the atmosphere of the room including the vinyl house A hypochlorous acid water spraying device for deodorizing bacteria, in the hypochlorous acid water of the aquarium container, an ultra-fine atomization generating device that arranges an ultrasonic vibrator on the bottom of the tray container Since it is immersed and suspended, even if the depth of 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 allows the hypochlorous acid water to reach approximately 4 to 5 micrometers. Can be efficiently generated from the surface of the water, and the ultra-fine mist of hypochlorous acid water that employs the ultrasonic method spreads to all corners of the indoor space, and efficiently produces mist that is not hot. And it can be sprayed gently.

  In addition, the sprayed mist disappears immediately, but since the components do not fall, it is possible to ride the wind far and spread to every corner of the room to sterilize the air, and hypochlorous acid water is safe. As it is made from the ingredients, inhaling a sprayed mist will not affect your health.

  Furthermore, the ultra-fine atomization generator itself is not directly bottomed in the water tank container, but floats in the hypochlorous acid water, so even if a forced rigid 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 in a state where it is buffered and protected by fluid hypochlorous acid water. Will not be given directly. Moreover, maintenance of the ultrafine atomization generator becomes easy.

  The aquarium container is equipped with an ultrasonic oscillator that drives the ultrasonic oscillator of the ultrafine atomization generator, and the ultrasonic oscillator has a surface that is immersed in hypochlorous acid water. Turn on the power source of the ultrasonic oscillator, and turn off the power source of the ultrasonic oscillator triggered by the disappearance of hypochlorous acid water on the surface of the ultrasonic oscillator due to the inclination of the water tank container Since the water level sensor is equipped in the ultra-fine atomization generator, even if the water on the surface of the ultrasonic oscillator of the ultra-fine atomization generator runs out due to tilting of the water tank container, the power of the ultrasonic oscillator is automatically turned off. Therefore, it is possible to prevent damage to the ultrasonic transducer of the ultrafine atomization generator due to careless oscillation drive under anhydrous conditions.

  Since the aquarium container has a volume that can secure at least one volume to be sprayed in the vinyl house and can be moved by a mount with gripping parts equipped with wheels such as casters and tires, the hypochlorous acid water A large amount of ultra-fine mist can be sprayed over a wide area over a long period of time, and transportation in a large-area room becomes easy.

  The nozzle is formed by a flexible bellows-shaped cylindrical member attached to the opening on the top surface of the water tank container, and the back of the nozzle is a superfine atomized hypochlorous acid water sprayed from the nozzle. Since the blower for diffusing the water is provided in the room, the ultrafine mist of hypochlorous acid water can be sprayed in a wide range by the cooperation of the nozzle and the blower even in a room having a large area.

  An embodiment of the present invention will be described in detail below with reference to the drawings. In the drawings, reference numeral 1 indicates a weakly acidic hypochlorous acid water for improving an indoor environment in an agricultural facility such as a vinyl house. It is a hypochlorous acid water spraying device for decontaminating and deodorizing by 9.

  As shown in FIGS. 1 and 2, the hypochlorous acid water spraying device 1 has an upper part that can be opened by a lid part 2a and can store therein a predetermined amount of hypochlorous acid water 9 described later (cooler). ) A box type water tank container 2 and an ultrasonic oscillator 3 with a power source for exciting and driving an ultrasonic vibrator 4a of an ultrafine atomization generator 4 described later have wheels 5a such as casters and tires at four corners on the lower surface. A vertically long U-shaped frame-shaped gripping portion 5b is mounted on a pedestal 5 which is erected at the end and is movable.

  As shown in FIGS. 1 to 3, a nozzle 6 for spraying hypochlorous acid water 9 formed by a flexible bellows-shaped cylindrical member is attached to an opening formed on the top surface of the lid 2a. A blower 8 (two in FIG. 2 and FIG. 3) for diffusing the ultrafine atomized hypochlorous acid water 9 sprayed from the nozzle 6 into the room is provided on the back part thereof. In FIG. 2, two nozzles 6 are arranged in parallel. 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 vibrator 4a of the ultrafine atomization generator 4 is provided. Has been done.

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

  Further, an opening 4c is formed at the center of each side wall surface of the four sides of the ultrafine atomization generator 4 (tray container), and hypochlorous acid water 9 enters (introduces) into the tray container from the side 4 directions. You can do it. As a result, the ultra-fine atomization generator 4 maintains a floating state at a predetermined depth position (for example, even if the water surface is grazing or a depth of several centimeters is acceptable) (see FIG. 5).

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

  As shown in FIGS. 4 and 5, a water level sensor 7 for turning on and off the power supply is provided at an end of the inner bottom surface of the tray container forming the ultrafine atomization generating device 4 and is erected in a substantially U-frame shape. . The water level sensor 7 is electrically connected to the power source of the ultrasonic oscillator 3, and the power source of the ultrasonic oscillator 3 is in a state where the surface of the ultrasonic oscillator 4a is immersed in the hypochlorous acid water 9. Is turned on (oscillation state). On the other hand, the power of the ultrasonic oscillator 3 is turned off (non-oscillation state) when the hypochlorous acid water 9 on the surface of the ultrasonic oscillator 4a disappears due to the inclination of the water tank container 2.

  The water level sensor 7 is a method of detecting the electrostatic capacity between a pair of electrodes or between one electrode and a metal tank to obtain the level, and an electric state in space and an electric state in full time. The level is detected based on the difference between. As the water level sensor 7, for example, in the case of an electrostatic capacitance type level switch, the detection unit is composed of a detection electrode and a ground electrode which are insulated from each other, and detects the presence or absence of a measurement object from the change in electrostatic capacitance generated between these two electrodes. To do.

  The aquarium container 2 has a volume capable of ensuring a volume capable of being sprayed into at least one vinyl house. Further, if the stock solution having a concentration of 200 PPM is diluted four 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. Further, the amount of spraying per one piece of vinyl house is preferably 10 L for 2 hours, but the present invention is not limited to this. For example, spraying is performed for 3 to 4 hours for the vinyl house 2 and further for 2 to 3 hours at a concentration of 50 PPM to 65 PPM.

  Next, an example of the use and operation of the configuration configured as described above will be described. First, the lid 2a of the water tank container 2 is opened and the pair of ultrafine atomization generators 4 are housed inside. The external ultrasonic oscillator 3 is electrically connected to the electrodes of the individual ultrafine atomization generators 4 via, for example, a cable 4b with an alligator plug.

  Then, the aforesaid predetermined amount of hypochlorous acid water 9 is stored in the water tank container 2 and the lid portion 2a is closed. After that, the power source of the ultrasonic oscillator 3 is turned on and a high frequency oscillation signal is sent to the ultrafine atomization generator 4 to drive all the ultrasonic transducers 4a to be excited at the same time.

  At this time, the ceramic vibrating element converts the high-frequency power generated by the ultrasonic oscillator 3 into mechanical vibration, and generates a strong ultrasonic wave from the ultrasonic vibrator 4a, which is about 4 to 5 micrometers of hypochlorous acid water 9. Ultrafine particles are generated from the water surface of the hypochlorous acid water 9 and are sprayed to the outside from the nozzle 6 while being diffused into the room by the blower 8.

  When the water tank container 2 tilts and the hypochlorous acid water 9 on the surface of the ultrasonic vibrator 4a of the ultrafine atomization generator 4 disappears, the power of the ultrasonic oscillator 3 is turned off by the water level sensor 7 ( The vibration drive of the ultrasonic transducer 4a is stopped). As a result, it is possible to prevent damage to the ultrasonic vibrator 4a due to the empty vibration when the ultrasonic vibrator 4a is not immersed in the hypochlorous acid water 9.

  The hypochlorous acid water spraying device according to the present invention may be applied to various other purposes such as a virus infection prevention measure in a hospital or an influenza epidemic prevention measure for livestock in winter.
