Description

[Detailed Description of the Invention] (Purpose of the Invention) <Industrial Application Field> The present invention is designed to prevent mosquitoes, flies, etc. This invention relates to a device for repelling flying pests that prevents them from entering.

<Background of the Invention> In places such as hospitals and pharmaceutical factories where work must be carried out in a sanitary environment, a method of maintaining a sanitary environment is to turn the workplace into a clean room or set up a so-called vestibule in front of the workplace. This prevents insects from entering from outside. However, even in places where a sanitary environment must be maintained, such as food processing factories and school lunch facilities,
Because there is a lot of traffic between the workplace and the outside, such as when raw materials are brought in or products are shipped, the workplace is not set up as a clean room or a vestibule is set up before entering the workplace. There were certain limits to maintaining a sanitary environment. That is, for example, in food processing factories and the like, a large number of transparent resin belt-like sheets are hung like curtains at the entrances and exits of workplaces to allow people to freely enter and exit, and to keep the entrances and exits closed at all times. However, even if such measures were taken, the band-shaped seal would be opened each time a person entered or exited the building, and there was no way to prevent flies or other insects from entering or bringing in dust, and it was difficult to take countermeasures.

Technical matters attempted to be developed> The present invention was conceived against this background, and
Focusing on the habit of insects such as mosquitoes and flies to avoid flying when fog occurs, we attempted to develop a device that utilizes this habit to effectively prevent the entry of these types of flying pests. It is something that

These inventions attempt to achieve the above object.

<Operation of the Invention> The present invention provides a liquid spraying device equipped with a nozzle in the communication area between the workplace and the outside, and sprays mist from the nozzle, thereby preventing flying pests from entering the workplace through the repellent action of the fog. This is to prevent

In addition, dust floating in the air and trying to enter from the outside absorbs moisture and falls, and dust attached to people's clothing is blown away by the slightest breeze and also absorbs moisture and falls. Or, it becomes fixed to clothing and no longer flies up. Furthermore, a repellent chamber is provided in the communication section, and a sensor for detecting a passing object is provided at the entrance to the repellent chamber, so that mist is ejected from the nozzle in response to a detection signal from the sensor.

<Examples> The present invention will be specifically described below based on illustrated examples. Reference numeral 1 denotes a flying pest repellent device according to the present invention, and as shown in FIG. A spray device 1a is installed above the repellent chamber E. The place where this spray device 1a is installed does not necessarily have to be in the repellent room E, but rather in the communication area T between the workplace R and the outside U, where flying pests are practically kept in the workplace R. If there is a possibility of entry into the interior, it can be installed, for example, at the upper edge of the window G as shown in FIG. This flying pest repellent device 1 is
It is equipped with a spray device 1a and a tank 2, which are the main components,
The spray device 1a includes a water storage chamber 3, a suction pipe 4, and a nozzle 5. To explain these components that are stored, the tank 2 is a relatively deep container, and an outlet 8 is formed at the lower side of the tank, and a water surface with a constant height H is formed at the upper part of the tank 2. A level gauge 9 is provided to detect the water surface height H in order to maintain the water level. For example, this level gauge 9 includes a plurality of electrode rods 1 having different lengths.
0, and the water surface height H is detected depending on which electrode rod 10 the water surface reaches. The level gauge 9 may be of a float type instead of using the electrode rod 10. The level gauge 9 is connected to a solenoid valve 12 installed in the water pipe 11, and the solenoid valve 12 is opened and closed according to the water surface height H determined by the level gauge 9. . By opening and closing the electromagnetic valve 12, the water W from the water pipe 11 is supplied or stopped, so that the water W in the tank 2 always maintains a constant water surface height H.

Next, a conduit pipe 13 is connected to the outflow port 8 in the tank 2, and the other end of the conduit pipe I3 is connected to the inlet port 14 formed at the bottom of the water storage chamber 3, thereby connecting the tank 2 and the water storage chamber. 3 are in communication. The water storage chamber 3 is, for example, a gutter-shaped one formed along the longitudinal direction of the storage box 6 as shown in FIG. There is. Since it is in communication with the tank 2 through the conduction pipe 13, the water W in the tank 2 flows toward the water storage chamber 3, and the water surface height in the water storage chamber 3 is the same as the water surface height H in the tank 2. It's high. Next, a suction pipe 4 is arranged from the water storage chamber 3 to the outside of the water storage chamber 3. One end of this suction pipe 4 is located below the water surface of the water storage chamber 3, and a nozzle is installed at the other end. 5 is provided.

Since the purpose of the present invention is to atomize the water W, a gas atomization nozzle as shown in FIG. 4 is used as the nozzle 5, as an example. This gas atomization nozzle is a type that atomizes liquid by colliding high-velocity air with it, and the liquid is atomized by pressurizing it, flowing it by gravity, or using the suction force of a gas stream. Suction or supply. In this embodiment, among these liquid suction methods, the suction force of a gas flow is used, but other methods may of course be used. An air supply pipe 17 is attached to the nozzle 5, and the air supply pipe 17 is further connected to a near compressor 18. Further, the nozzle 5 may be one that substantially sends mist into the repellent chamber E, and in addition to the gas atomization nozzle, a fan-shaped spray nozzle, an impact nozzle, etc. can also be used. In addition, with a gas atomization nozzle, the size of droplets is related to the ratio of air to water, and if the amount of air is small, large water droplets are likely to form, so it is necessary to provide sufficient air flow to generate fog. It is necessary to keep the droplets fine. Also, if the air pressure is high, the air velocity increases and the water droplets become finer. The position of such a nozzle 5 is set to be higher than the water surface height H by a nozzle height h.

Incidentally, depending on the nozzle height h, the water W from the suction pipe 4
The storage box 6 in which the zero-order water storage chamber 3, the suction pipe 4, and the nozzle 5, in which the suction state and the draining state of the nozzle 5 are adjusted, will be described. This box consists of a box main body 6a that is open downward, and a lid 6b that is provided to cover the open part, and has a horizontally long rectangular box shape as a whole. A conduit hole 21 for guiding the conduit tube 13 into the storage box 6 is formed on the edge surface of the box body 6a, and an air supply tube 17 is formed on the side surface of the box body 6a for guiding the conduit tube 17 into the storage box 6. Air supply pipe hole 22 for
form.

Further, an anchor 23 is provided on the upper surface of the box body 6a, and the spray device 1a is suspended from the ceiling of the repellent chamber E by this anchor 23. In addition, the box body 6a and the lid part 6b are connected to each other by a hinge 24.
One side is connected with , and the other side is a connecting piece 2 that can be opened and closed.
5, it is in a closed state. In addition, four small holes 26, for example, are formed in the lid part 6b, and the tip of the nozzle 5 housed in the storage box 6 projects outward from each small hole 26. Next, near the repellent room E, there is a power distribution I! for operating the flying pest repellent device 1! 127 is provided. This power distribution block 27 includes a main power switch 27a, a pressure adjustment dial 27b for the near compressor 18, and a spray time adjustment dial 2 that determines the spray time in the avoidance chamber E.
7C and a pilot lamp 27d. Further, at the entrance to the repellent room E, a work place sensor 28 and an outside sensor 29 are provided for the work place R and the outside U, respectively.

The workplace side sensor 28 and the outside side sensor 29 use, for example, a phototube to detect the passage of a passing object M such as a worker or a forklift within the detection range and send the signal to the switchboard 27.

The flying pest repellent device 1 of the present invention has the above structure, and when using this device, first turn on the main power switch 27a of the power distribution board 27 and turn on the pilot lamp 27d. In this state, use the pressure adjustment dial 27b and the spray time adjustment dial 27C to
Adjust the spray pressure and spray time of the mist. When a passing body M such as a worker moves from the workplace R to the outside U in such a state, the workplace side sensor 28 detects the presence of the passing body M, and a signal thereof is sent to the power distribution i27. Then, in the switchboard 27, air is sent from the air supply pipe 17 to the nozzle 5 by turning on the conduit switch on the air compressor 18 side for a certain period of time. Such air flow creates a negative pressure at the tip of the nozzle 5, sucks up the water in the water storage chamber 3 into the suction pipe 4, and sprays mist from the nozzle 5 for a certain period of time. During this time, the passing body M moves from the work place R to the outside U. On the other hand, when moving from the outside U to the workplace R, the outside sensor 29 is activated and mist is similarly sprayed into the avoidance room E. In this way, while the mist is being sprayed, any flying pests that try to enter the workplace R from the outside U are prevented from entering by the repellent action of the mist. Further, when floating dust enters from the outside U, the dust adsorbs moisture and falls. Furthermore, dust adhering to people's clothing also absorbs moisture and is fixed to the clothing, preventing it from flying up. Next, the water storage chamber 3 is
When the water W in the tank is consumed, the water W is supplied from the tank 2 to the water storage chamber 3 through the conduction pipe 13, and the reduced water W in the tank 2 is supplied from the water pipe 11 by the operation of the level gauge 9. be done.

Therefore, the water surface height H of the tank 2 and water storage chamber 3 is always maintained at a constant height.

(Effects of the Invention) In the present invention, since the water W is atomized to prevent the entry of flying pests and dust, a sanitary environment can be maintained in the workplace R.

Furthermore, since water is used, the running cost is low, and there is no harm to the objects M passing through, such as workers.

Furthermore, by providing a repellent chamber E and arranging the spray device 1a therein, the entire repellent chamber E will be sprayed with mist, and the entry of flying pests from the outside U can be more effectively prevented. At the same time, it is also possible to prevent dust from entering into the workplace R.

Furthermore, if a workplace side sensor 28 and an external side sensor 29 are provided, mist can be sprayed as needed.

Furthermore, since the flying pest repellent device 1 is relatively compact, it can be installed even in narrow places such as the upper edge of a window G or a ventilation hole.
