[0027] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0028] like Figures 1 to 10 As shown, a cross-infection prevention disinfection device includes a disinfection vehicle body 1 and an ultraviolet lamp group 2 with an angle adjustment function. A mounting groove 101 is provided on the top of the disinfection vehicle body 1. A sliding control component 3 for controlling the reciprocating sliding of the ultraviolet lamp group 2 is provided inside the mounting groove 101. A swing control component 4 for allowing the ultraviolet lamp group 2 to swing back and forth while sliding back and forth is provided on the top of the disinfection vehicle body 1. An adjustment component 5 for adjusting the amplitude of the reciprocating sliding of the ultraviolet lamp group 2 is provided on the sliding control component 3.

[0029] like Figures 1 to 3 As shown, the ultraviolet lamp group 2 includes an ultraviolet lamp 201, and a mounting bracket 202 is fixedly installed at one end of the ultraviolet lamp 201 close to the disinfection vehicle body 1. A support arm 203 is hinged inside the mounting bracket 202, and a positioning screw 204 for positioning the position of the ultraviolet lamp 201 is provided on the mounting bracket 202; by adjusting the angle of the ultraviolet lamp 201, after the angle of the ultraviolet lamp 201 is adjusted, the position of the mounting bracket 202 and the ultraviolet lamp 201 is locked by the positioning screw 204, and then the disinfection step can be carried out.

[0030] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 9As shown, the sliding control assembly 3 includes a turntable 301 rotatably arranged inside the mounting groove 101, and a follower shaft 302 is rotatably provided at the edge of the top of the turntable 301. The follower shaft 302 rotates with the turntable 301, and the outer surface of the follower shaft 302 is movably connected to a track member 303. The outer surface of the follower shaft 302 fits with the inner wall of the track member 303. The outer surface of the track member 303 is symmetrically fixedly connected to two support rods 304. The outer surfaces of the two support rods 304 are both covered with sleeves 305. The ends of the two sleeves 305 away from the turntable 301 are fixedly installed in the mounting groove. The side wall of 101, the core of the sleeve 305 is hexagonal, the support rod 304 is slidably set inside the sleeve 305, and the mounting groove 101 is located directly below the turntable 301 and is fixedly installed with a driving member 7 (a motor) for controlling its rotation. The turntable 301 is controlled to rotate circumferentially by the driving member 7, and then the cooperation between the follower shaft 302 and the track member 303 is utilized to allow the swing control component 4 to drive the ultraviolet lamp group 2 to slide back and forth (the cooperation between the set support rod 304 and the sleeve 305 can ensure the stability of the track member 303 during reciprocating sliding).

[0031] like Figures 2 to 9 As shown, the swing control assembly 4 includes a fixed base 401 fixedly mounted on the top of the track member 303, and a rotating shaft 402 is rotatably provided on the top of the fixed base 401. A gear 403 is fixedly mounted on the outer surface of the rotating shaft 402. A top cover 6 is fixedly mounted on the top of the disinfection vehicle body 1, and a slot 601 is provided on the top cover 6 corresponding to the position of the rotating shaft 402. The slot 601 is symmetrically and staggeredly provided with multiple gear groups 602 along the sliding direction of the rotating shaft 402. The support arm 203 is fixedly mounted on the top of the rotating shaft 402, and a gap is left between the support arm 203 and the top cover 6. When the track member 303 slides back and forth, the cooperation between the gear 403 and the multiple symmetrically and staggered gear groups 602 can make the rotating shaft 402 rotate back and forth (switch back and forth between clockwise rotation and counterclockwise rotation), so that the support arm 203 is fixedly mounted on the top of the rotating shaft 402, so that the ultraviolet lamp 201 can swing back and forth.

[0032] like Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the adjustment component 5 includes a sliding groove 501 provided on the turntable 301, a sliding block 502 is provided for sliding inside the sliding groove 501, and the bottom end of the follower shaft 302 is rotatably connected to the sliding block 502, and the sliding block 502 is located at the bottom end of the follower shaft 302 and has a rotating hole. The follower shaft 302 is connected to the rotating hole through a bearing, so that the friction between the follower shaft 302 and the track member 303 can be reduced by using the above-mentioned bearing. A screw rod 503 is provided for rotation inside the sliding groove 501, and the sliding block 502 is threadedly connected to the screw rod 503. One end of the screw rod 503 passes through the turntable 301, and a knob 504 is fixedly installed on the end of the screw rod 503 outside the turntable 301. The turntable 301 is A rotating hole is provided at the position of the screw rod 503, and the screw rod 503 is connected to the rotating hole through a bearing. The above-mentioned bearing can reduce the friction force when the screw rod 503 rotates, and improve the stability of the screw rod 503 when rotating. The disinfection vehicle body 1 is inlaid with a baffle 102 on the front side of the installation groove 101. Through the adjustment component 5, the baffle 102 can be removed to contact the knob 504, and then the screw rod 503 is rotated by the knob 504 to make the sliding block 502 slide inside the sliding groove 501, thereby adjusting the distance between the follower shaft 302 and the center of the turntable 301. The larger the distance, the larger the reciprocating sliding amplitude of the track member 303, and the smaller the distance, the smaller the reciprocating swing amplitude of the track member 303.

[0033] The usage process is as follows:

[0034] S1: If Figures 1 to 3 As shown, when in use, first push the disinfection vehicle body 1 to the position where disinfection is required, then adjust the angle of the ultraviolet lamp 201. After the angle of the ultraviolet lamp 201 is adjusted, lock the position of the mounting bracket 202 and the ultraviolet lamp 201 by the positioning screw 204, and then the disinfection step can be carried out;

[0035] S2: If Figure 2 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 9 As shown, during disinfection, the medical staff withdraws first, and then controls the turntable 301 to rotate circumferentially through the driving member 7. Then, by utilizing the cooperation between the follower shaft 302 and the track member 303, the swing control assembly 4 can drive the ultraviolet lamp group 2 to slide back and forth (the cooperation between the provided support rod 304 and the sleeve 305 can ensure the stability of the track member 303 during the reciprocating sliding);

[0036] S3: If Figures 2 to 9As shown, when the track member 303 slides back and forth, the gear 403 cooperates with the plurality of symmetrically staggered gear groups 602 to allow the shaft 402 to reciprocate (switching back and forth between clockwise and counterclockwise rotation), thereby allowing the support arm 203 fixedly mounted on the top of the shaft 402 to allow the ultraviolet lamp 201 to swing back and forth;

[0037] S4: In summary, the UV lamp group 2 slides back and forth and swings back and forth at the same time, so that its irradiation range is no longer limited to a fixed area, but can cover a larger space. The synergistic effect of sliding and swinging forms a sweeping light path. The dynamic irradiation method allows the UV light to reach more corners, greatly increasing the overall irradiation area, avoiding differences in disinfection effects caused by excessive or insufficient local irradiation, and ensuring the consistency and reliability of disinfection.

[0038] S5: If Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, by removing the baffle 102 through the adjustment assembly 5, the knob 504 can be accessed, and then the screw rod 503 is rotated by the knob 504 to make the sliding block 502 slide inside the sliding groove 501, thereby adjusting the distance between the follower shaft 302 and the center of the turntable 301. The larger the distance, the greater the reciprocating sliding amplitude of the track member 303, and the smaller the distance, the smaller the reciprocating swing amplitude of the track member 303.

[0039] S6: As Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the adjustment component 5 allows the amplitude of the reciprocating sliding to be adjusted, and the swing amplitude can also be adjusted, so that the ultraviolet lamp group 2 can be quickly adapted to objects of different sizes, thereby completing the disinfection task in a shorter time and improving the disinfection efficiency (for larger objects, the sliding stroke and swing amplitude can be increased to ensure that the entire surface of the object can be fully irradiated; for smaller objects, the corresponding amplitude can be reduced to avoid unnecessary energy waste and improve energy utilization efficiency).
