[0008] <> Hereinafter, a drug dispensing device according to one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the attached drawings. In each figure, the components of the chemical dispensing device are shown in a simplified and schematic manner. Therefore, the size (dimensions) and ratios of each component shown in the figures, the placement of each component, and the spacing between components are not particularly limited and should be set to a suitable level depending on the application and operating environment of the chemical dispensing device, as well as the components contained in the chemical. In addition, some equipment and components may be omitted in the drawings; for example, in Figure 3, the drip prevention plate 46, which will be described later, is omitted.

[0009] Furthermore, in this specification, "vertical direction" means the vertical direction of the drug dispensing device, that is, the direction perpendicular to the horizontal plane on which the drug dispensing device is installed, and is parallel to the vertical direction when the drug dispensing device is in use.

[0010] The chemical ejector 10 according to this embodiment is used for the purpose of exterminating pests and vermin such as cockroaches and rats in buildings such as stores (especially kitchens, dining halls, etc.) in restaurants, etc., houses, facilities such as schools and hospitals, offices, and warehouses. The chemical ejector 10 is a stationary / placement type device and is installed at a predetermined location in the building as shown in FIG. 1.

[0011] In this embodiment, the chemical ejector 10 ejects a chemical containing mainly an insecticidal component for exterminating cockroaches and a repellent component for repelling rats. Here, "ejection" includes spraying and discharging, and the method of ejecting the chemical includes continuously ejecting the chemical and intermittently (intermittently) ejecting the chemical.

[0012] As shown in FIG. 1, the chemical ejector 10 has an ejection unit 12, a chemical tank 14, a housing unit 24, a support unit 32, and a control controller 30. Further, as shown in FIG. 2, the chemical ejector 10 includes an adjustment unit 16, a connecting shaft 18, and a rotating unit 22.

[0013] As shown in FIGS. 1 and 2, the ejection unit 12 includes a nozzle 40 having an opening 42 and a holder 44. The ejection unit 12 sucks the chemical in the chemical tank 14 through a tube 38 by a pump provided in the holder 44. The ejection unit 12 ejects the sucked chemical from the opening 42 of the nozzle 40 at a predetermined pressure. In this embodiment, as shown in FIGS. 1 and 2, in order to prevent the chemical ejected from the opening 42 of the nozzle 40 from dripping downward and adhering to devices and components, a drip prevention plate 46 is arranged directly below the nozzle 40 and is fixed to the holder 44.

[0014] The housing unit 24 is a case (container) arranged below the ejection unit 12. The adjustment unit 16 and the rotating unit 22 are housed in the housing unit 24.

[0015] The adjustment unit 16 moves the ejection unit 12 to adjust the position of the surface at the opening 42 of the nozzle 40 (hereinafter referred to as the "opening surface") in order to eject the drug from the top to the bottom of the target object. More specifically, in this embodiment, as shown in Figures 1 to 3, the ejection unit 12 is provided at the tip of the connecting shaft 18. More precisely, the lower surface of the holder 44 is fixed to the tip of the connecting shaft 18. Also, as shown in Figure 3, a pivot shaft 20 is provided at the other end of the connecting shaft 18.

[0016] As shown in Figure 3, the adjustment unit 16 uses the power of a motor (not shown) to move the ejection unit 12 in an arc around the pivot shaft 20 to adjust the position of the opening. That is, the forward and backward tilting movements of the connecting shaft 18 are repeated alternately at a constant period to adjust the position of the opening. By making this adjustment, the adjustment unit 16 enables the ejection of the agent from the nozzle 40 from the top to the bottom of the object. Since the connecting shaft 18 moves along with the movement of the ejection unit 12, a groove is formed in the upper part of the housing unit 24.

[0017] The rotating part 22 can rotate the ejection part 12 to the right or left around the connecting shaft 18 using the power of a motor (not shown). More specifically, in this embodiment, as shown in Figure 2, a rotating shaft 23 is provided in the center of the rotating part 22, and an adjustment part 16 is installed on the upper surface of the rotating part 22. By using the power of a motor (not shown), as shown in Figures 2 and 4, the rotating part 22 is rotated clockwise or counterclockwise around the rotating shaft 23, causing the adjustment part 16, the connecting shaft 18, and the ejection part 12 to rotate in the same direction around the connecting shaft 18. This rotation causes the position of the opening surface in the nozzle 40 to rotate left or right around the connecting shaft 18.

[0018] In this embodiment, as shown in Figures 2 and 4, the connecting shaft 18 rotates together with the rotating part 22, allowing the nozzle 40 to rotate 90° clockwise and 90° counterclockwise from a predetermined position. However, the rotation angle is not limited to this and may be set as appropriate. The upper part of the housing part 24, which has the groove, may be structured to allow the position of the groove to be adjusted in accordance with the rotation of the rotating part 22.

[0019] As shown in Figure 1, the control controller 30 controls the drive equipment of the drug dispensing device 10, specifically the drug supply pump, the adjustment unit 16 (motor that rotates the pivot shaft 20), and the rotating unit 22 (motor that rotates the pivot shaft 23). The control controller 30 is composed of a microcomputer and a control circuit, and controls the above-mentioned controlled equipment according to the control program (including forward and reverse rotation control for motors).

[0020] The support section 32 constitutes the lower part of the drug dispensing device 10 and is positioned directly below the housing section 24. The support section 32 supports the dispensing section 12, the housing section 24, and the adjustment section 16 and rotating section 22, etc., which are housed within the housing section 24. As shown in Figure 1, the support section 32 in this embodiment is composed of a support column 34 and a tripod 36 assembled to the support column 34.

[0021] The support column 34 extends vertically, and when the chemical dispensing device 10 is in use, the lower end of the support column 34 touches the floor or ground. In this embodiment, as shown in Figure 5, the support column 34 is extendable and retractable vertically, allowing the height of the chemical dispensing device 10 to be adjusted. The height of the dispensing section 12 can be changed using this support column 34. The extension and retraction of the support column 34 may be performed manually or electrically using a motor or other driving force. When the support column 34 is extended and retracted electrically, the height of the support column 34 may be automatically controlled by the control controller 30.

[0022] Each leg of the tripod 36 is positioned around the support column 34 and extends diagonally relative to the support column 34, and its inclination angle relative to the ground or floor is adjustable, as shown in Figure 6. The smaller the inclination angle of each leg, the larger the space occupied by the tripod 36, and the more stably the chemical spraying device 10 is fixed. The tripod 36 may also be structured so that the length of each leg can be individually adjusted so that the chemical spraying device 10 can be installed horizontally on an inclined ground or floor.

[0023] <<Example of use of a drug dispensing device according to one embodiment of the present invention>> An example of using the drug dispensing device 10 will now be described. The drug dispensing device 10 is installed in a designated location within a building, such as a cafeteria or kitchen. The drug dispensing device 10 is installed as shown in Figure 1. At this time, the position of the opening 42 of the nozzle 40 is set to a predetermined position as shown in Figure 4.

[0024] The drug dispensing device 10 periodically dispenses the drug after being installed in a predetermined location. Specifically, at a predetermined time, the control controller 30 activates the pump and starts supplying the drug to the nozzle 40. As a result, the dispensing unit 12 dispenses the drug from the opening 42 of the nozzle 40 at a predetermined pressure for a certain period of time at a predetermined time.

[0025] At this time, the control controller 30 controls the adjustment unit 16 to rotate the connecting shaft 18 in the forward or reverse direction around the pivot shaft 20. This moves the spraying unit 12 in the forward or reverse direction in an arc, adjusting the position of the opening and spraying the chemical from the top to the bottom of the target object. More specifically, the connecting shaft 18 repeatedly tilts forward and backward alternately, spraying the chemical from the nozzle 40 of the spraying unit 12 from the top to the bottom of the target object (see Figure 3). Target objects include places where pests and rodents are likely to appear, nearby walls, kitchen equipment and its gaps. By periodically spraying the chemical using the chemical spraying device 10 of the present invention in this way, it is possible to drastically reduce pests and rodents such as cockroaches and rats.

[0026] The above effects are particularly effective against cockroaches. As shown in Figure 7, cockroaches (indicated by the symbol G in Figure 7) have a habit of moving up and down on the target object (indicated by the symbol O in Figure 7). By spraying the insecticide from the top to the bottom of the target object O, it becomes possible to effectively exterminate cockroaches with a small amount of insecticide (reducing their population by 99%).

[0027] Furthermore, the control controller 30 controls the rotating part 22 to rotate the ejection part 12, the connecting shaft 18, and the adjustment part 16 in forward or reverse direction around the rotating shaft 23 (see Figures 2 and 4). This allows the agent to be ejected not only in one direction (up and down), but also in multiple up and down directions and multiple left and right directions, so that the target object is evenly covered with the agent.

[0028] <<Regarding other embodiments>> In the above description, one embodiment of the drug dispensing device and its usage method of the present invention has been explained. However, this is merely an example to facilitate understanding of the present invention and does not limit it. In other words, the present invention can be modified and improved without departing from its spirit. Furthermore, it goes without saying that the present invention includes equivalents thereof.

[0029] In the above-described embodiment, a support section 32 composed of a support column 34 and a tripod 36 was used as an example, but the invention is not limited to this, and the support section 32 may be composed of only a tripod 36. When the support section 32 is composed of only a tripod 36, it is preferable to use a tripod having a structure similar to that of a surveying tripod. Alternatively, the support section 32 may be composed of a support column 34 and a base plate made of a flat plate attached to the lower end of the support column 34.

[0030] In the above-described embodiment, a nozzle 40 is installed that sprays the chemical at a predetermined pressure using a pump. However, this nozzle 40 may be a device that sprays microparticles of the chemical using wind power. This makes it possible to exterminate pests such as cockroaches and rats more efficiently with a smaller amount of chemical.

[0031] In the above-described embodiment, the spraying section 12 is made to move in an arc shape by rotating the connecting shaft 18, to which the spraying section 12 is fixed, around the pivot shaft 20, thereby adjusting the position of the opening surface of the nozzle 40 so that the drug can be sprayed from the top to the bottom of the object. The present invention is not limited to this configuration. For example, the spraying section 12 may be fixed to a rod of a piston mechanism, and this rod may reciprocate vertically by the piston mechanism, thereby moving the position of the opening surface of the nozzle 40 vertically and adjusting it so that the drug can be sprayed from the top to the bottom of the object.

[0032] Furthermore, in the above-described embodiment, the rotating part 22 rotates the ejection part 12, the connecting shaft 18, and the adjustment part 16 integrally. However, the configuration is not limited to this, and the ejection part 12, the connecting shaft 18, and the adjustment part 16 may be rotated integrally by rotating the housing part 24.

[0033] Furthermore, although the above-described embodiment described a stationary / freestanding drug dispensing device 10 that is installed and used in a predetermined location, it is not limited to this, and for example, it may be a drug dispensing device equipped with a self-propelled mechanism that can move on the ground or floor.

[0034] Furthermore, if the target object is a gap between kitchen equipment and a wall or floor, a gap between kitchen equipment, a gap within kitchen equipment, etc., and its surrounding area (meaning the area from which the pesticide spraying device can spray pesticide), the pesticide spraying device having some or all of the above-described components may further include an LED irradiation unit that irradiates light into the gap or the inside of the gap in kitchen equipment (for example, the inside of a motor or precision equipment) where pests and rodents are hiding (for example, their dens). Specifically, as shown in Figure 8, the pesticide spraying device 10 of the present invention may be provided with an LED irradiation unit 51 that irradiates light into the gap between kitchen equipment 100 or the inside of the gap in kitchen equipment 100 where pests and rodents are hiding. In this way, by providing the LED irradiation unit 51 in the pesticide spraying device 10 of the present invention, it becomes possible to irradiate light into the gap between kitchen equipment 100 or the inside of the gap in kitchen equipment 100 where pests and rodents are hiding. As a result, the negative attraction of pests and rodents to light can be used to drive them out of gaps. Furthermore, the pesticide spraying device 10 of the present invention can spray the pesticide onto target objects O, such as gaps between kitchen equipment 100 and their surroundings, in places where pests and rodents pass through, thereby bringing the pesticide into contact with the pests and rodents, making it possible to exterminate pests and rodents more efficiently.

[0035] The LED illumination unit 51 may include, for example, an LED tube light or an LED strip light, but is not limited to these. Furthermore, there may be one light unit installed, or multiple lights may be installed. In this embodiment, the power supply unit 50 controls the irradiation of light by the LED irradiation unit 51, and the drug dispensing device 10 controls the power supply unit 50 via the connecting line 52. However, the drug dispensing device 10 may also control the power supply unit 50 wirelessly. Examples of wireless communication include wireless LAN and Bluetooth. Furthermore, it is preferable that the light irradiation by the LED irradiation unit 51 be performed simultaneously with or before / after the spraying of the chemical by the spraying unit 12 of the chemical spraying device 10. This makes it possible to more effectively exterminate pests and rodents with a smaller amount of chemical. [Explanation of Symbols]
