[0034] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0035] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0036] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0037] See Figures 1 to 4 ,in, Figure 1 The structure of the ultraviolet disinfection device in one embodiment is shown; Figure 2 The structure of the disinfection section channel in one embodiment is shown; Figure 3 The structure of the ultraviolet emission source in one embodiment is shown; Figure 4 The structure of the output rotating reflector and the rotating drive device is shown. Using the ultraviolet disinfection channel system provided by this invention, ultraviolet disinfection of goods can be achieved, while reducing the probability of workers being exposed to ultraviolet radiation and minimizing the health impact on workers.

[0038] The ultraviolet disinfection device 1 provided by the present invention may include an input channel 11, a disinfection channel 12, and an output channel 13, wherein:

[0039] The input channel 11 may include a starting input unit 111 and an input reversing unit 112. The input reversing unit 112 is used to reverse the direction of the goods output from the starting input unit 111, and the input reversing unit 112 is located at the output end of the starting input unit 111. Here, the input reversing unit 112 may be, but is not limited to, any one of a swing wheel machine, a steering belt machine, or a steering roller machine.

[0040] The disinfection section channel 12 may include an ultraviolet disinfection chamber 121 with an input opening and an output opening, wherein the input opening is located on the output end side of the input reversing mechanism 112. In this embodiment, the ultraviolet disinfection chamber 121 may include a conveying area 1211 and a plurality of ultraviolet emission sources 1212 surrounding the conveying area 1211. The conveying area 1211 is located between the input opening and the output opening. The conveying unit in the conveying area 1211 may be, for example, a roller, with light-transmitting gaps between each roller, or the conveying unit may be a light-transmitting element. The conveying unit may specifically be a roller, or a light-transmitting conveyor belt that allows ultraviolet light to pass through, or a mesh conveyor that allows ultraviolet light to pass through, etc.

[0041] A reflector plate 12123 for reflecting ultraviolet light into the ultraviolet disinfection chamber 121 is also provided on the outer periphery of the plurality of ultraviolet emission sources 1212. The direction of the input opening of the ultraviolet disinfection chamber 121 is at a first preset angle with the transport direction of the starting input machine 111, that is, the ultraviolet light emitted from the input opening cannot be directly emitted to the starting input machine 111, thus ensuring that personnel at the starting input machine 111 will not be exposed to ultraviolet radiation when placing goods, reducing the impact on personnel health and safety. In addition, to further reduce the ultraviolet light emitted to the starting input machine 111, an entrance curtain 113 is also provided between the input reversing machine 112 and the starting input machine 111.

[0042] In this invention, such as Figure 3 As shown, the ultraviolet emission source 1212 may include a microwave electrodeless ultraviolet lamp 12121 and a microwave head 12122 for controlling the microwave electrodeless ultraviolet lamp 12121, while the reflector 12123 may include a W-shaped reflector for reflecting the ultraviolet rays emitted by the microwave electrodeless ultraviolet lamp 12121 into the ultraviolet disinfection chamber 121. Multiple microwave electrodeless ultraviolet lamps 12121 are respectively located on the top, bottom, left, and right sides of the ultraviolet disinfection chamber 121, thereby forming a surrounding disinfection of the goods. The multiple W-shaped reflectors are respectively located on the top, bottom, left, and right sides of the ultraviolet disinfection chamber 121, thus enabling the ultraviolet rays emitted by the microwave electrodeless ultraviolet lamp 12121 to irradiate the goods as much as possible, improving the ultraviolet disinfection effect.

[0043] The output channel 13 may include an output reversing mechanism 131 and a terminal output mechanism 132. The output reversing mechanism 131 is used to reverse the direction of goods output from the output opening, while the terminal output mechanism 132 is used to output the goods output by the output reversing mechanism 131. The terminal output mechanism 132 is located at the output end of the output reversing mechanism 131. Here, the direction of the output opening of the ultraviolet disinfection chamber 121 forms a second preset angle with the transport direction of the terminal output mechanism 132. That is, the ultraviolet rays emitted from the output opening of the ultraviolet disinfection chamber 121 cannot directly reach the terminal input mechanism 132. Therefore, it can be ensured that personnel at the terminal output mechanism 132 will not be exposed to ultraviolet radiation when retrieving goods, reducing the impact on personnel health and safety. In addition, to further reduce the ultraviolet rays emitted to the terminal output mechanism 132, an exit curtain 133 is also provided between the output reversing mechanism 131 and the terminal output mechanism 132.

[0044] In this invention, the first preset angle and the second preset angle may be equal or unequal. In a preferred embodiment, the first preset angle and the second preset angle are equal, both being 90 degrees or approximately 90 degrees, so that personnel can place and retrieve goods on the same side of the ultraviolet disinfection device 1.

[0045] This invention utilizes ultraviolet (UV) emission sources arranged around the perimeter of the conveying area to disinfect goods through irradiation. Simultaneously, reflectors within the UV disinfection chamber reflect as much UV radiation as possible onto the goods, enhancing the disinfection effect. Furthermore, by incorporating input and output reversing mechanisms within the UV disinfection chamber, with the input opening facing at a first preset angle to the transport direction of the initial input machine and the output opening facing at a second preset angle to the transport direction of the final output machine, personnel located at the initial input machine and the final output machine are prevented from direct UV irradiation, reducing safety hazards.

[0046] In one specific embodiment of this method, an input auxiliary disinfection channel 14 is provided between the input channel 11 and the disinfection channel 12. Input rotating reflectors 1213 are provided on both the top and bottom sides of the input opening. The reflection direction of the input rotating reflectors 1213 faces the output opening, meaning that the ultraviolet light reflected by the input rotating reflectors 1214 can be reflected into the output auxiliary disinfection channel 15 to disinfect the tail surface of the goods in this channel. The incident direction of the input rotating reflectors 1213 faces the interior of the ultraviolet disinfection chamber 121. Furthermore, the output auxiliary disinfection channel 15 has a roller input machine 141. Additionally, a set of reflectors can be provided on both sides of the input rotating reflectors 1213. This set of reflectors may include a large reflector and a small reflector, with the small reflector positioned higher than the large reflector. Both the large and small reflectors face the opposite set of reflectors. The multiple large and small reflectors further increase the ultraviolet radiation dose to the goods.

[0047] More specifically, the input auxiliary disinfection channel 14 also includes a reflective input channel wall 143 to ensure that as much ultraviolet light emitted into the input auxiliary disinfection channel 14 as possible is reflected back onto the goods for disinfection. The input channel wall 143 can be the side wall and top wall of the input auxiliary disinfection channel 14. Furthermore, an entrance inner curtain 142 is provided at the junction of the input section channel 11 and the input auxiliary disinfection channel 14 to reduce the amount of ultraviolet light emitted from the input auxiliary disinfection channel 14 into the input section channel 11.

[0048] In one specific embodiment of this method, an auxiliary output disinfection channel 15 is further provided between the disinfection section channel 12 and the output section channel 13. The top and bottom sides of the output opening of the ultraviolet disinfection chamber 121 are provided with output rotating reflectors 1214. The reflection direction of the output rotating reflectors 1214 faces the input opening side, meaning that the ultraviolet light reflected by the output rotating reflectors 1214 can be reflected into the auxiliary input disinfection channel 14 to disinfect the first surface of the goods in that channel. The incident direction of the output rotating reflectors 1214 faces the interior of the ultraviolet disinfection chamber 121. Here, the auxiliary output disinfection channel 15 has a roller output machine 151. Similarly, a set of reflectors can also be provided on both sides of the output rotating reflectors 1214. Since the structure is the same as that of the aforementioned output rotating reflectors 1213, it will not be described again here to avoid repetition.

[0049] More specifically, the output auxiliary disinfection channel 15 also includes a reflective output channel wall 153 to ensure that as much ultraviolet light emitted into the output auxiliary disinfection channel 15 as possible is reflected onto the goods for disinfection. Furthermore, an outlet inner curtain 152 is provided at the junction of the output section channel 13 and the output auxiliary disinfection channel 15 to reduce the amount of ultraviolet light emitted from the output auxiliary disinfection channel 15 into the output section channel 13.

[0050] It is understandable that by setting the input auxiliary disinfection channel 14 and the output auxiliary disinfection channel 15, the disinfection time of goods inside the ultraviolet disinfection device 1 is increased, thereby achieving a more comprehensive disinfection effect.

[0051] Preferably, the curtains of the entrance outer curtain 113, the entrance inner curtain 142, the exit outer curtain 133, and the exit inner curtain 152 provided by the present invention can all be provided with a wave-absorbing layer to further reduce the possibility of microwaves being emitted to the outside world and reduce the safety hazards to staff and the environment.

[0052] In this invention, the input rotating reflector 1213 and the output rotating reflector 1214 can have the same structural configuration, specifically, as shown in the example below. Figure 4 As shown, taking the structure of the output rotating reflector 1214 as an example, the output rotating reflector 1214 can be fixedly mounted on a rotatable shaft 1215. A fixing plate 1216 can be installed at both ends of the shaft 1215 for fixation, allowing the shaft 1215 to rotate relative to the fixing plate 1216. The fixing plate 1216 is fixedly mounted on the body of the ultraviolet disinfection chamber 121. A rotary driver 1217 can also be installed and fixed on one side of the fixing plate 1216. The drive motor 1217 can be connected to one end of the shaft 1215 via a coupling. Here, corresponding bearings can be installed on the fixing plate 1216 to fix both ends of the shaft 1215, or one bearing can fix the output shaft of the drive motor 1217, and another bearing can fix one end of the shaft 1215. Thus, the rotation angle of the output rotating reflector 1214 can be controlled by controlling the rotary driver 1217.

[0053] In this invention, the input reversing machine 112 and / or the output reversing machine 131 are any one of a swing wheel machine, a steering belt machine, or a steering roller machine, to realize the reversing transport of goods.

[0054] In this invention, both the input channel 11 and the output channel 13 include roller conveyors or belt conveyors for transporting goods.

[0055] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
