[0027] The intelligent spray disinfection vehicle provided in this embodiment can be used in stations or airports. Of course, it can also be used for disinfection of other walls and is not limited to the use in this embodiment.

[0028] The intelligent spray disinfection vehicle comprises a vehicle body 11, a controller, a plurality of obstacle avoidance sensors, a liquid storage tank 12 for storing disinfectant, and a spray assembly. The vehicle body 11 has a hollow inner cavity, the liquid storage tank 12 is arranged in the inner cavity, the spray assembly comprises a water pump 13, an atomizing nozzle 14, a hose 15, and a swing assembly. One end of the swing assembly is hinged to the outer wall side of the vehicle body 11, and swings up and down relative to the outer wall of the vehicle body 11. The atomizing nozzle 14 is arranged at the other end of the swing assembly. One end of the hose 15 is connected to the water pump 13, and the other end is arranged along the length direction of the swing assembly and connected to the atomizing nozzle 14. The water pump 13 is placed at the inner bottom end of the liquid storage tank 12; a plurality of obstacle avoidance sensors are respectively arranged on the front end face and two side faces of the vehicle body 11, a crawler track 16 is provided at the lower end of the vehicle body 11, the controller is electrically connected to the obstacle avoidance sensor, and when the disinfection vehicle is moving, the obstacle avoidance sensor senses an obstacle and transmits a signal to the controller, and the crawler track 16 turns to avoid the obstacle.

[0029] In the above-mentioned intelligent spray disinfection vehicle, one end of the swing assembly is hinged to the side of the outer wall of the vehicle body 11, and the atomizing nozzle 14 is arranged at the other end of the swing assembly, and the swing assembly can swing up and down relative to the outer wall of the vehicle body 11, and the atomizing nozzle 14 on the swing assembly faces the wall, and the water pump 13 draws the disinfectant from the liquid storage tank 12, and flows to the atomizing nozzle 14 through the hose 15. The disinfectant is sprayed after being atomized by the atomizing nozzle 14, and the height of the atomizing nozzle 14 is adjusted by the swing assembly, so that different height positions of the wall can be disinfected; the water pump 13 is placed at the inner bottom end of the liquid storage tank 12, and the disinfectant in the liquid storage tank 12 can be as much as possible during the disinfection process. The venom is completely extracted to avoid waste; the obstacle avoidance sensor is arranged on the front face and two sides of the vehicle body 11, and the obstacle avoidance sensor senses the front and both sides of the vehicle body 11 to avoid the disinfection vehicle from hitting obstacles in the front or on the sides during movement, and also avoids the swing component from colliding with the side wall. The controller controls the movement of the disinfection vehicle according to the signal of the obstacle avoidance sensor, and no human intervention is required. The disinfection vehicle realizes intelligent disinfection, reduces labor costs, and improves disinfection efficiency; the vehicle body 11 moves on the track 16, and will encounter various complex grounds when disinfecting the external wall. The track 16 enables the vehicle body 11 to adapt to various grounds, thereby improving the adaptability of the disinfection vehicle.

[0030] The controller is electrically connected to the obstacle avoidance sensor through a wire, and the obstacle avoidance sensor is an ultrasonic sensor or an infrared sensor; the track 16 is driven by a drive motor, and the drive motor is connected to the differential, and the differential is connected to the tracks 16 on both sides. The drive motor is electrically connected to the controller. When the disinfection vehicle needs to turn, the controller controls the drive motor to rotate, and the differential makes the speeds of the tracks 16 on both sides different, and the disinfection vehicle will turn toward the side with lower speed.

[0031] The controller is electrically connected to the water pump 13 , and the controller controls the water pump 13 to pump the disinfectant into the hose.

[0032] Specifically, the swing assembly includes a swing plate 17, two stretching rods 18, and a stretching motor 19. One end of the swing plate 17 is hinged to the outer wall side of the vehicle body 11, and the atomizing nozzle 14 is arranged at the other end of the swing plate 17; slide grooves 20 are formed on both sides of the swing plate 17, one end of the stretching rod 18 is hinged to the outer wall side of the vehicle body 11 and connected to the stretching motor 19, and a slider 21 is provided at the other end, and the slider 21 is hinged to the end of the stretching rod 18, and the two sliders 21 are respectively embedded in the swing plate 17 has two slide grooves 20; the stretching motor 19 drives the stretching rod 18 to swing up and down, so that the slider 21 slides in the slide groove 20, and pulls the swing plate 17 to swing up and down, the slide groove 20 has an upper groove surface facing the atomizing nozzle 14 and a lower groove surface away from the atomizing nozzle 14, when the slider 21 slides to abut the upper groove surface of the slide groove 20, the swing plate 17 swings upward to fit the outer wall of the vehicle body 11, and when the slider 21 slides to abut the lower groove surface of the slide groove 20, the swing plate 17 swings downward to be horizontally arranged.

[0033] The controller is electrically connected to the stretching motor 19, and the controller controls the rotation angle of the stretching motor 19, thereby controlling the swing angle range of the stretching rod 18, to avoid rigid collision between the stretching rod 18, the swing plate 17 and the outer wall of the vehicle body 11, or rigid collision between the slider 21 and the slide groove 20, which may cause damage to the parts.

[0034] The stretching motor 19 is placed in the outer wall of the car body 11, and the output shaft is connected to one end of the stretching rod 18 to drive the stretching rod 18 to swing up and down. The slider 21 on the other end of the stretching rod 18 is embedded in the slide groove 20 of the swing plate 17 and slides in the slide groove 20. Since one end of the swing plate 17 is also hinged with the outer wall of the car body 11, when the stretching rod 18 is driven by the stretching motor 19 to swing up and down, the stretching rod 18 will drive the swing plate 17 to swing up and down, and the slider 21 slides up and down in the slide groove 20 during the swinging; when the slider 21 abuts the upper groove surface of the slide groove 20, the swing plate 17 swings upward to fit the outer wall of the car body 11, and the atomizing nozzle 14 on the swing plate 17 is at the highest point. On the contrary, when the slider 21 abuts the lower groove surface of the slide groove 20, the swing plate 17 swings downward to be horizontally arranged, and the atomizing nozzle 14 on the swing plate 17 is at the lowest point; the up and down swinging process of the swing plate 17 realizes the adjustment of the height of the atomizing nozzle 14.

[0035] More preferably, the slide groove 20 is located at the upper part of the swing plate 17 , so that the stretching rod 18 drives the swing plate 17 to swing up and down through the slider 21 with less effort, thereby reducing the power consumption of the stretching motor 19 .

[0036] When the slider 21 slides to abut against the upper groove surface of the slide groove 20 , the stretching rod 18 and the swing plate 17 are arranged in the same straight line.

[0037] The spacing between the two stretching rods 18 is greater than or equal to the width of the swing plate 17. When the slider 21 slides to abut the upper groove surface of the slide groove 20, the swing plate 17 fits the outer wall of the vehicle body 11. At this time, the entire swing plate 17 is between the two stretching rods 18. The stretching rod 18 and the swing plate 17 are arranged in the same straight line and fit together on the outer wall of the vehicle body 11, reducing the space occupied by the stretching rod 18 and the swing plate 17.

[0038] The outer wall side of the vehicle body 11 is recessed inward to form a pipeline groove 22 and a fitting groove 23. The pipeline groove 22 and the fitting groove 23 are arranged in a stepped manner, and the width of the pipeline groove 22 is smaller than the fitting groove 23. When the swing plate 17 swings upward to fit the outer wall of the vehicle body 11, the swing plate 17 and the stretching rod 18 are simultaneously embedded in the fitting groove 23, and the hose 15 arranged along the length direction of the swing plate 17 is embedded in the pipeline groove 22. Other pipeline wires on the swing plate 17 can also be embedded in the pipeline groove 22.

[0039] When the swing plate 17 and the stretching rod 18 are inserted into the fitting groove 23 , the swing plate 17 fits against the bottom groove surface of the fitting groove 23 , and the bottom groove surface of the fitting groove 23 limits the swing of the swing plate 17 and the stretching rod 18 at the highest point.

[0040] The side groove surfaces on both sides of the fitting groove 23 are arranged to be inclined outward, and the two side surfaces of the stretching rod 18 are also arranged to be inclined outward along the direction away from the vehicle body 11. Therefore, it is easier to align the stretching rod 18 when it is embedded in the fitting groove 23, and the stretching rod 18 and the swing plate 17 can be accurately embedded in the fitting groove 23, avoiding the stretching rod 18 from colliding with the edge of the fitting groove 23 and causing failure to embed.

[0041] When the swing plate 17 and the stretching rod 18 are simultaneously inserted into the fitting groove 23 , the outer end surface of the swing plate 17 , the outer end surface of the stretching rod 18 , and the outer wall side surface of the vehicle body 11 are arranged flush.

[0042] The thickness of the swing plate 17 and the stretching rod 18 is equal to the depth of the fitting groove 23. Therefore, after the swing plate 17 and the stretching rod 18 are embedded in the fitting groove 23, the outer end faces of the swing plate 17 and the stretching rod 18 and the outer wall side of the vehicle body 11 are arranged flush, making the outer surface of the entire vehicle body 11 smoother, reducing protrusions, and avoiding collisions between protrusions and other objects.

[0043] A rotating shaft 24 is provided at the end of the swing plate 17 facing away from the vehicle body 11, a connecting block 25 is fixed to the lower part of the atomizing nozzle 14, the connecting block 25 is sleeved on the rotating shaft 24, two torsion springs 26 are sleeved on the rotating shaft 24, one end of the torsion spring 26 is fixed to the connecting block 25 of the atomizing nozzle 14, and the other end is fixed to the swing plate 17; the atomizing nozzle 14 has a nozzle 27, and the torsion spring 26 ensures that the direction of the nozzle 27 of the atomizing nozzle 14 is always maintained in parallel with the length direction of the swing plate 17.

[0044] The atomizing nozzle 14 is sleeved on the rotating shaft 24 through the connecting block 25 and can rotate relative to the rotating shaft 24. The elastic force of the torsion spring 26 keeps the direction of the nozzle 27 of the atomizing nozzle 14 parallel to the length direction of the swing plate 17. When the swing plate 17 swings downward to the lowest point and is arranged horizontally, the direction of the nozzle 27 is also horizontal; during the upward swinging process of the swing plate 17, the direction of the nozzle 27 gradually tilts upward, thereby expanding the height range of the atomizing nozzle 14 spraying disinfectant.

[0045] The top end surface of the fitting groove 23 is recessed upward to form a nozzle groove 28, and the nozzle groove 28 is in the shape of an arc surface, and the upper end surface of the atomizing nozzle 14 is in the shape of an arc surface; when the swing plate 17 is embedded in the fitting groove 23, the atomizing nozzle 14 is embedded in the nozzle groove 28, and the nozzle groove 28 squeezes the atomizing nozzle 14, so that the atomizing nozzle 14 remains in a horizontal arrangement, and the torsion spring 26 is in a compressed state.

[0046] At this time, the swing plate 17 has been embedded in the fitting groove 23. In order to prevent the atomizing nozzle 14 from spraying disinfectant on the outer wall of the vehicle body 11, when the swing plate 17 swings to the highest point, the upper end surface of the atomizing nozzle 14 can be squeezed through the nozzle groove 28, so that the atomizing nozzle 14 rotates on the rotating shaft 24, and finally the direction of the nozzle 27 is horizontal and facing the wall; at this time, the torsion spring 26 is compressed, and when the swing plate 17 swings downward again, the elastic force of the torsion spring 26 causes the atomizing nozzle 14 to gradually reset until the direction of the nozzle 27 is arranged parallel to the length direction of the swing plate 17.

[0047] From top to bottom, the outer wall side of the vehicle body 11 is tilted inward at an angle of 45-60°. The tilted outer wall of the vehicle body 11 allows the maximum upward swinging angle of the swing plate 17 to be within a reasonable range, thereby preventing the disinfectant sprayed from the atomizing nozzle 14 from being able to be sprayed onto the wall due to an excessively large angle.

[0048] The nozzle 27 of the atomizing nozzle 14 is annular, and the width of the annular nozzle 27 is less than or equal to 0.5 mm, thereby enhancing the atomization effect of the sprayed disinfectant. The small width of the nozzle 27 can increase the spraying speed of the disinfectant, so that the disinfectant can be sprayed farther to ensure that it is sprayed on the wall.

[0049] In the direction away from the vehicle body 11, the diameter of the nozzle 27 gradually increases, that is, the nozzle 27 is in the shape of a ring-shaped expansion, which is beneficial to increase the coverage area after the disinfectant is sprayed out and improve the disinfection spraying efficiency of the wall.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
