A switching valve 179 is provided in the first T-shaped tube 163 and the second T-shaped tube 165 via a rotary shaft 179a, which can switch the passage by operating the operation handle 123.

  Next, the procedure and operation for performing the disinfection operation of the vehicle 1 using the disinfection device 100 having the above-described configuration will be described.

  When the vehicle 1 is stopped in front of the entrance gate of a farm or the like, and the driver presses the power button 151 of the operation box 150 to turn on the power, and presses either the automatic button 152 or the manual button 153, the control signal is controlled through the wiring 155. The electromagnetic valve 177 is sent to the box 120, the sterilizing liquid L constantly pressurized in the disinfecting liquid tank 110 passes through the second liquid pipe 139, the inlet pipe 174, and the outlet pipe 175, and further the first liquid pipe 136. The disinfecting liquid L is ejected from the respective ejection nozzles 140 to the surface of each tire 3 and below the chassis 2 at a time for several seconds. In addition, when the vehicle 1 is driven slowly while the disinfecting liquid L is ejected for several seconds, the disinfecting liquid L can be surely distributed over the entire surface of each rotating tire 3.

In the disinfectant tank 110, compressed air stored in the air tank 7 passes from the second air pipe 132 through the first T-shaped pipe 163, the connecting pipe 164, the second T-shaped pipe 165, and further through the third air pipe 133. 3, the third T-tube 168 shown in FIG. 3 branches into the fourth air pipe 134 and the fifth air pipe 135, and the compressed air is sent from the fourth air pipe 134 into the tank, and at the same time from the fifth air pipe 135. Compressed air is sent into the vertical pipe 115, and compressed air is sent into the disinfectant L in the tank from the air hole 115A. In this compressed air supply operation, the operation handle 123 is held in a horizontal posture, and as shown by circles A and B in FIG. 4, the first T-tube 163 includes only the first introduction part 163A and the lead-out part 163B. Only the introduction portion 165A and the first lead-out portion 165B communicate with the second T-shaped tube 165.

  The inside of the disinfectant tank 100 is sent from the air tank 7, and the disinfectant L is constantly pressurized from above by the compressed air introduced from the compressed air introduction port 114, and the compressed air ejected from the air hole 115 </ b> A of the vertical pipe 115. As a result, the stock solution of the disinfectant L and water are constantly stirred. The air tank 7 is supplied with compressed air from the air compressor 6 in order to supply the derived compressed air.

  When the disinfection work of the vehicle 1 is completed before the entrance gate of a farm or the like, the vehicle 1 is entered from the entrance gate. Since the driver can operate the operation box 150 while sitting on the driver's seat, the disinfection work of the vehicle 1 can be performed efficiently and easily. There is no need to get off the driver's seat at the entrance gate and manually disinfect the tires every time the farm arrives, and it is not necessary to install an expensive disinfection device at the entrance gate in the farm. This can reduce the driver's burden and the farm burden associated with disinfection work.

  The remaining amount of the disinfecting liquid L in the disinfecting liquid tank 110 can be visually checked with the level gauge 118, but when the remaining amount of the disinfecting liquid L decreases, a replenishment operation is performed. First, the compressed air in the disinfectant tank 110 needs to be exhausted.

The lid 122 is opened, and the switching operation handle 123 is switched from the horizontal posture of FIG. 4 to the standing posture of FIG. As a result, as shown in circles C and D in FIG. 5, the first T-shaped tube 163 includes the second introducing portion 163C and the deriving portion 163B, and the second T-shaped tube 165 includes the introducing portion 165A and the second deriving portion 165C. Switch to communicate with each other. Simultaneously with the switching operation, the compressed air in the disinfectant tank 110 is discharged from the exhaust port 116 as shown by the arrows in FIG. 5, the first exhaust pipe 138, the introduction pipe 171, the first T-shaped pipe 163, the connection pipe 164, the second T It passes through the character tube 165 and the outlet tube 178 and is quickly discharged into the skirt 119 from the second exhaust tube 138A.

  Next, the cap 113 </ b> A is opened, and the stock solution of the disinfectant L and water are supplied from the supply port 113. As the stock solution, iodine-based, chlorine-based, aldehyde-based or other complex liquids are used, and diluted by mixing with water at a predetermined ratio. The ratio of water to the stock solution is, for example, 200 to 1000 times that of stock solution 1. When the stock solution and water for the disinfectant are supplied, the cap 113A is closed, the switching operation handle 123 is switched to the horizontal position, compressed air is introduced from the air tank 7 into the disinfectant tank 110, and pressurization and agitation are performed simultaneously. In the disinfectant tank 110, the stock solution and the water are automatically agitated by the compressed air ejected from the air hole 115A of the vertical pipe 115, and the disinfectant L is efficiently generated.

  When the replenishment operation of the disinfecting liquid L is completed, preparation for disinfection operations of each part of the vehicle 1 is performed.

FIG. 8 shows another embodiment. As shown in the figure, the 4T-tube 180 is interposed between the front of the solenoid valve 177 of the inlet tube 174 and outlet tube 175 of the lower flow of the second liquid pipe 139, of the 4T-tube 180 second An inlet of the third liquid pipe 181 is connected to the outlet 180B, and a gun type ejection nozzle 182 is attached to the outlet of the third liquid pipe 181. Since the gun-type ejection nozzle 182 is supplied with a sterilizing liquid that is constantly pressurized up to the front of the solenoid valve 177, the sterilizing liquid L can be ejected from the ejection nozzle portion 184 at the tip by pulling the lever 183. It has become. As a result, disinfection work for drivers and workers entering the farm can be performed together. A button type injection nozzle or the like can be used instead of the gun type injection nozzle 182.

FIGS 9 (A) without (C) shows an example of the arrangement of the ejection nozzle 140. FIG. 4A shows an example in which the disinfecting liquid is ejected from above to the front and rear tires 3, and FIGS. 5B and 5C show examples in which the disinfecting liquid is ejected from the front and rear directions of the respective tires 3. Moreover, when a double tire is arrange | positioned at right and left, such as a large truck, it cannot be overemphasized that the ejection nozzle 140 is arrange | positioned for every tire. The ejection nozzle 140 can be arranged not only in the vicinity of the tire but also on any of the lower part of the chassis, the front surface, the side surface, the back surface, and the top surface.

  The vehicle 1 may be equipped with a disinfectant tank 110 and a water tank. A control box 120, a pipe 130, a jet nozzle 140, and an operation box 150 shown in FIGS. The pipe 130, the ejection nozzle 140, and the operation box 150 can also be used as the disinfecting liquid tank 110. After the disinfection work, the attached disinfectant solution may solidify on the side, front, back, etc. of the body. In such a case, solidification of the disinfectant solution can be prevented by ejecting water after a certain time when the disinfecting effect is obtained.

  The vehicle 1 includes a truck, a bus, a passenger car, a two-wheeled vehicle, a freight car, a passenger car, and the like. A wide variety of liquids intended for sterilization, sterilization, and the like can be applied to the disinfecting liquid. The operating voltage of the sterilizer 100 can be either 12V or 24V.

  The disinfecting apparatus of the present invention can be widely used as an apparatus for disinfecting various parts of a vehicle (tires, undercarriage, side, front, back, top surface, etc.). Moreover, it can be used not only for the disinfectant but also for water washing.
