[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] like Figures 1 to 6As shown, the first embodiment of the present invention provides a courier disinfection and sterilization device, which mainly includes a housing 23, a conveying mechanism, a disinfectant spraying mechanism and a spraying control mechanism. Figure 1 and Figure 2 As shown, the conveying mechanism passes through the housing 23. The conveying mechanism of the present invention is composed of a first roller conveying unit 1 and a second roller conveying unit 2. Both conveying units are roller conveying units, so there is a gap between the rollers. Therefore, disinfectant can be sprayed upward from the gap to disinfect the bottom of the package. Figure 2 As shown, the conveying surfaces of the two units (i.e., the bearing surfaces of the rollers) form a 90-degree angle between them, and the two units are arranged at an angle. In this way, the package will slide on the roller toward the intersection of the two conveying units. The conventional package is generally in the shape of a rectangular parallelepiped. When the package slides to the intersection of the two conveying units, at least two vertical surfaces are attached to the first roller conveying unit 1 and the second roller conveying unit 2 respectively.

[0044] The disinfectant spraying mechanism designed in the present invention includes two spraying units, namely the first spraying unit and the second spraying unit. The first spraying unit is located above the conveying mechanism, while the second spraying unit is located below the conveying mechanism. The first spraying unit and the second spraying unit have the same basic structure, both including a first bracket 3 and a second bracket 4. The first bracket 3 and the second bracket 4 in the same spraying unit are vertical, and the front and rear positions are staggered to avoid interference. Figure 2 As shown, the first bracket 3 and the second bracket 4 in the first spraying unit are parallel to the conveying surfaces of the first roller conveying unit 1 and the second roller conveying unit 2, respectively. Similarly, the first bracket 3 and the second bracket 4 in the second spraying unit are also parallel to the conveying surfaces of the first roller conveying unit 1 and the second roller conveying unit 2, respectively. A plurality of nozzles 5 are arranged on the two first brackets 3 and the two second brackets 4, and the nozzles 5 are perpendicular to the corresponding conveying surfaces. The nozzles 5 located below the conveying mechanism can spray the two downward sides of the package through the gap between the rollers, while the nozzles 5 located above the conveying mechanism can directly spray the two upward sides of the package, so that all four sides can be sprayed. Since the spray itself has a certain spraying range, in fact, when the package passes through the spraying range, its front and back sides can also be covered. Therefore, the present invention can ensure the full coverage of the disinfectant and fully disinfect the package.

[0045] In order to accurately spray the package, thereby reducing the consumption of disinfectant and avoiding excessive spraying of the package causing the package to become damp, the present invention designs a spray control mechanism. The spray control mechanism can start the corresponding number and position of nozzles 5 to spray the package according to the size of the package, thereby reducing the number of nozzles 5 actually used, maximizing the use of disinfectant and reducing waste.

[0046] Specifically, the spray control mechanism designed in the present invention includes two sets of infrared detection components and four sets of control components. Each set of infrared detection components includes a plurality of infrared sensors, and the plurality of infrared sensors are arranged in a straight line in sequence. The two sets of infrared detection components are respectively fixed on the first roller conveying unit 1 and the second roller conveying unit 2. Figure 2 As shown, taking the first roller conveyor unit 1 as an example, the corresponding multiple infrared sensors are arranged in sequence along the axis of the roller, that is, these infrared sensors are parallel to the conveying surface of the corresponding conveying unit. Since one side of the package will be against the first roller conveyor unit 1, when the package passes through the infrared sensor, the size of the side of the package can be inferred based on the number and position of infrared rays blocked by the package. Two groups of infrared sensors located on the first roller conveyor unit 1 and the second roller conveyor unit 2 can cooperate to measure the width and height of the package.

[0047] The four groups of control components designed in the present invention are respectively located on the first bracket 3 and the second bracket 4 on the two spraying units. According to the width and height of the package provided by the infrared detection component, the nozzles 5 at the corresponding positions can be controlled to start spraying, while the nozzles 5 beyond the package range will not be started, thereby realizing the spraying of disinfectant on demand.

[0048] The basic structures of the four control components are the same. To facilitate the description of the specific structure of the control components, the control components on the first bracket 3 in the second spray unit are taken as an example. Figures 3 to 6 As shown, the control assembly of the present invention is designed with multiple valve bodies 6 to control the start and stop of multiple nozzles 5 respectively. The valve body 6 is fixed on the first bracket 3, and the nozzle 5 is directly connected to the corresponding valve body 6, and the valve body 6 is connected to the main liquid supply pipeline through a connecting pipe, and the main liquid supply pipeline is connected to the disinfectant storage barrel 24. The disinfectant storage barrel 24 is pressurized so that the disinfectant can flow in the connecting pipe. A valve stem 7 is provided on the valve body 6, and the opening and closing of the valve body 6 can be adjusted by rotating the valve stem 7. When the valve body 6 is opened, the disinfectant is sprayed out from the nozzle 5, and when the valve body 6 is closed, the disinfectant will not be sprayed out from the nozzle 5.

[0049] like Figures 3 to 6 As shown, in order to simultaneously drive multiple valve bodies 6 to open and close, the present invention fixes a limit plate 8 on the first bracket 3, and movably inserts multiple parallel rods 9 on the limit plate 8. A rotating sleeve 10 is fixed on one end of the rod 9 close to the valve body 6. The rotating sleeve 10 is provided with an inner hexagonal groove and can be sleeved on the hexagonal head on the valve stem 7. A first gear 11 is fixed on the side of the rod 9 located on the limit plate 8 away from the valve body 6.

[0050] The first bracket 3 is slidably mounted with a first rack 12 parallel to the limit plate 8 and meshed with all the first gears 11. In this way, when the first rack 12 moves, all the first gears 11 can be driven to rotate. If the rotating sleeve 10 is sleeved on the top of the valve stem 7 at this time, the valve stem 7 will also rotate, thereby controlling the opening and closing state of the nozzle 5. The present invention has a cylinder 13 fixedly mounted on the first bracket 3, and the movable end of the cylinder 13 is fixedly connected to the first rack 12. Therefore, the cylinder 13 can change the opening and closing state of the valve body 6.

[0051] In order to allow the rotating sleeve 10 to be automatically sleeved on the valve stem 7, the present invention is designed with a self-locking structure. Figure 5 As shown, the self-locking structure includes a spring 14 sleeved on the rod body 9, one end of the spring 14 abuts against the limit plate 8, and the other end abuts against the rotating sleeve 10, ensuring that the rotating sleeve 10 is always in close contact with the top of the valve stem 7.

[0052] After the above arrangement, when the cylinder 13 is working, all valve bodies 6 on the first bracket 3 will start and stop synchronously. However, the present invention also needs to be able to adjust the number of valve bodies 6 to be controlled, so as to cooperate with the infrared detection component to adjust the number of starts and stops of the nozzles 5. Therefore, the present invention designs an unlocking structure to facilitate the quick release of the connection between part of the rotating sleeve 10 and the valve stem 7 when needed, so as to maintain the closed state of part of the valve body 6, so that the cylinder 13 can only open the remaining valve bodies 6. The unlocking structure of the present invention includes a spherical lifting part 15 fixed to the end of the rod body 9, an unlocking plate 16 slidably mounted on the first bracket 3 and parallel to the limit plate 8, and a lifting slope 17 is provided at one end of the unlocking plate 16 close to the rod body 9. In this way, when the unlocking plate 16 moves toward the rod body 9, the lifting slope 17 can be against the lifting part 15, and give the lifting part 15 a thrust to move away from the valve body 6, so that the rotating sleeve 10 compresses the spring 14 and disengages from the valve stem 7. In this way, the unlocking plate 16 prevents the valve body 6 corresponding to this part of the rod body 9 from changing the open and closed state due to the action of the cylinder 13, thereby being able to adjust the number of nozzles 5 to be started. In order to drive the unlocking plate 16 to move, the present invention fixes a motor 19 on the first bracket 3, a second gear 20 is fixed on the output shaft of the motor 19, and a second rack 18 meshing with the second gear 20 is fixed on the unlocking plate 16, so that when the motor 19 is started, the unlocking plate 16 can be driven to move.

[0053] Working principle: When the express package is placed on the conveying mechanism, it will slide to the intersection of the first roller conveying unit 1 and the second roller conveying unit 2, so that the two sides of the package are respectively attached to the conveying surfaces of the first roller conveying unit 1 and the second roller conveying unit 2. When the package passes through the infrared detection component, the infrared detection component can detect the width and height of the package. According to the size information of the package, the motor 19 drives the unlocking plate 16 to move to control the number of nozzles 5 that need to be started. The cylinder 13 works, driving the valve stem 7 to rotate, so that the corresponding nozzle 5 sprays the disinfectant, thereby realizing the targeted adjustment of the spraying range according to the size of the package, thereby avoiding the waste of disinfectant, and the package can also be fully sprayed.

[0054] Embodiment 2:

[0055] On the basis of the first embodiment, considering the different distances between the nozzle 5 and the package, the spraying range and spraying density of the nozzle 5 will also change. In order to maintain a good spraying effect, it is necessary to be able to adjust the distance between the nozzle 5 and the package. In order to further improve the disinfection effect, such as Figure 2 As shown, the present invention further installs a first telescopic mechanism and a second telescopic mechanism on the housing 23, which are respectively used to adjust the positions of the first bracket 3 and the second bracket 4 in the first spraying unit, thereby adjusting the distance between the nozzle 5 and the conveying surface of the first roller conveying unit 1 and the conveying surface of the second roller conveying unit 2, and ensuring that the disinfectant can be evenly sprayed on the package surface at the most suitable distance. The structures of the first telescopic mechanism and the second telescopic mechanism are basically the same. Taking the first telescopic mechanism as an example, the first telescopic mechanism includes two telescopic guide rods 21 and an electric push rod 22. The two ends of the telescopic guide rod 21 are respectively fixedly connected to the housing 23 and the first bracket 3, which can provide a stable guiding effect. The two ends of the electric push rod 22 are also respectively fixedly connected to the housing 23 and the first bracket 3. The electric push rod 22 is responsible for accurately adjusting the distance between the first bracket 3 and the package according to the package size measured by the infrared sensor assembly, thereby maintaining the distance between the nozzle 5 and the package at an appropriate position.

[0056] Embodiment three:

[0057] In order to prevent the disinfectant from splashing around during disinfection, the present invention is provided with curtains 25 on both the front and rear sides of the housing 23. The curtains 25 can be pushed open when the package is moved, and the curtains 25 can block the splashing disinfectant.

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
