Description

Technical Field

[0001] The present invention relates to the technical field of UV-LED disinfection, and particularly relates to a UV-LED disinfection device and method. Background Art

[0002] For the liquid materials involved in surgical supplies, such as common disinfectants, cleaning liquids, or the materials used for surgical dressings, during the production and preparation process of such liquid materials, it is necessary to disinfect and sterilize them. Commonly, such as using a UV-LED lamp, when in use, the UV-LED lamp is directly used to disinfect the liquid, and at the same time, a reflector is used to increase the disinfection effect. The wavelength of the UV-LED lamp and the angle of the reflector are set constantly. However, during the specific use process, the liquid flow rate is in an unstable state. The constant settings of the wavelength and the reflector cannot well meet the use requirements, especially the disinfection effect at the middle position of the liquid is limited. The disinfection effect is related to the irradiation time and distance. When the flow rate increases, the irradiation time shortens, affecting the disinfection effect. For this reason, we propose a UV-LED disinfection device to solve the above problems. Summary of the Invention

[0012] In the above-mentioned UV-LED disinfection device, the driving member includes a transmission structure, a second gear, and a shaft body.

Second gears are installed on the three shaft bodies; A one-way bearing is installed on the shaft body corresponding to the first toothed ring seat, and the one-way bearing cooperates with the corresponding second gear.

[0013] A UV-LED disinfection method using the above-mentioned disinfection device includes the following steps: S1: The liquid is transported into the disinfection tank through the liquid inlet pipe fitting. When the liquid enters, it impacts the filter screen frame and drives the filter screen frame to rotate. When the filter screen frame rotates, the shielding member moves under the centrifugal force, thereby sealing and shielding the arc-shaped through holes on the filter screen frame. The sieve plate blocks the particulate impurities and collects them on the corresponding blades as the blades rotate. When the impact force of the liquid decreases, the shielding member resets, and the impurities collected on the blades at this time will be collected into the filter screen frame; S2: The liquid generates an impact on the arc plate through the impact pipe, which causes the lifting frame to move downward. The downward movement of the lifting frame drives the rack to move downward, and then drives the reflector to adjust the reflection angle through the first gear. When the liquid flow rate is fast and the impact force is large, the rotation angle is larger; S3: The rotation of the filter screen frame drives the rotation of the shaft rod frame. The rotation of the shaft rod frame drives the rotation of the shaft body through the transmission structure. The rotation of the shaft body drives the rotation of the first tooth ring seat, the third tooth ring seat, and the second tooth ring seat. By changing the branch pipe through which the liquid passes, the rotation angle of the shaft rod frame can be changed, thereby controlling whether the first tooth ring seat rotates; S4: The rotation of the first tooth ring seat drives the rotation of the UV-LED lamp, the pushing member, and the reflector together. During the rotation process, the pushing member causes the round rod to swing under the action of centrifugal force, thereby adjusting the angle of the UV-LED lamp. And the magnitude of the centrifugal force is related to the magnitude of the impact force of the liquid, so that the adjustment magnitude of the angle of the UV-LED lamp is coordinated with the liquid flow rate, and the UV-LED lamp and the reflector are used in cooperation for primary disinfection; S5: When the liquid continues to move downward through the first tooth ring seat, the liquid at the central position can directly enter the gathering pipe fitting and enter the third tooth ring seat through the connecting pipe, and then flow out through the mixing pipe fitting. At this time, the flowing out liquid contacts the liquid edge, completing the transportation of the central liquid to the edge position. And when the third tooth ring seat rotates, it drives the mixing pipe fitting to rotate together. At this time, under the cooperation of the tooth ring and the third gear, the extrusion roller rotates, and the extrusion roller plays an intermittent extrusion effect on the mixing pipe fitting during the rotation process, thereby changing the magnitude of the impact force of the liquid flowing out through the mixing pipe fitting, so that the liquid at the central position is fully transported to the edge and the position near the edge of the liquid; S6: The liquid continues to flow, and is disinfected twice by the UV-LED lamp on the second tooth ring seat, and finally flows out of the disinfection tank through the external pipe body.

[0014] Compared with the existing technology, the advantages of the present invention are: 1: Use two sets of UV-LEDs set at different heights to disinfect the liquid multiple times. At the same time, set a flow direction adjustment member and a liquid mixing member between the two sets of UV-LEDs to adjust the liquid after the first disinfection, adjust the liquid originally in the middle position to the edge position, and then cooperate with the lower UV-LED for re-disinfection to improve the disinfection effect.

[0015] 2: The reflection adjustment member is used to automatically adjust the angle of the reflector hood with the change of the liquid impact force, so as to better reflect the light emitted by the corresponding UV-LED lamp. When the liquid flow rate increases, the upper end of the reflector hood rotates towards the direction close to the liquid flow direction. At this time, the distance between the reflected ultraviolet rays and the liquid is shortened, increasing the disinfection effect in a short time.

[0016] 3: Use a filtering member to screen out solid particle impurities from the liquid before disinfection, effectively improving the disinfection effect of the UV-LED on the liquid. Moreover, the filtering member also has a self-collection function, automatically collecting impurities after use. At the same time, the filtering member can change the rotation direction by changing the flow direction of the liquid when it enters, thereby controlling the upper UV-LED to be in a rotating or static disinfection state.

[0027] Refer to Figures 1 - 20 , a UV-LED disinfection method, using the above disinfection device, includes the following steps: S1: The liquid is conveyed into the disinfection box 1 through the liquid inlet pipe fitting 38. When the liquid enters, it impacts the filter mesh frame 3 and drives the filter mesh frame 3 to rotate. When the filter mesh frame 3 rotates, the shielding member 22 moves under the centrifugal force, thereby hermetically shielding the arc-shaped through holes on the filter mesh frame 3. The sieve plate 5 blocks the particulate impurities and collects them on the corresponding blades as the blades rotate. When the impact force of the liquid decreases, the shielding member 22 resets. At this time, the impurities collected on the blades will be collected into the filter mesh frame 3; S2: The liquid generates an impact on the arc plate 23 through the impact pipe 6, which causes the lifting frame 20 to move downward. The downward movement of the lifting frame 20 drives the rack 18 to move downward, and then drives the reflector 16 to adjust the reflection angle through the first gear 17. When the liquid flow rate is fast and the impact force is large, the rotation angle is larger; S3: The rotation of the filter mesh frame 3 drives the rotation of the shaft rod frame 4. The rotation of the shaft rod frame 4 drives the rotation of the shaft body 39 through the transmission structure 14. The rotation of the shaft body 39 drives the rotation of the first ring gear seat 7, the third ring gear seat 31, and the second ring gear seat 8. By changing the branch pipe through which the liquid passes, the rotation angle of the shaft rod frame 4 can be changed, thereby controlling whether the first ring gear seat 7 rotates; S4: The rotation of the first ring gear seat 7 drives the UV-LED lamp 9, the pushing member 13, and the reflector 16 to rotate together. During the rotation of the pushing member 13, the round rod 10 swings under the action of centrifugal force, thereby adjusting the angle of the UV-LED lamp 9. And the magnitude of the centrifugal force is related to the magnitude of the impact force of the liquid, so that the adjustment magnitude of the angle of the UV-LED lamp 9 matches the liquid flow rate. The cooperation of the UV-LED lamp 9 and the reflector 16 is used for primary disinfection; S5: When the liquid continues to move downward through the first ring gear seat 7, the liquid at the central position can directly enter the converging pipe fitting 27, and then enter the third ring gear seat 31 through the connecting pipe 28, and then flow out through the mixing pipe fitting 33. At this time, the flowing-out liquid contacts the liquid edge, completing the transportation of the central liquid to the edge position. Moreover, when the third ring gear seat 31 rotates, it drives the mixing pipe fitting 33 to rotate together. At this time, under the cooperation of the ring gear 32 and the third gear 37, the squeezing roller 36 rotates. During the rotation of the squeezing roller 36, it has an intermittent squeezing effect on the mixing pipe fitting 33, thereby changing the magnitude of the impact force when the liquid flows out through the mixing pipe fitting 33, so that the liquid at the central position is fully transported to the edge and the inner position near the edge of the liquid; S6: The liquid continues to flow, and is secondarily disinfected by the UV-LED lamp 9 on the second ring gear seat 8, and finally flows out of the disinfection box 1 through an external pipe body.

10. A UV-LED disinfection method, using the disinfection device as claimed in claim 9, characterized in that: The following steps are involved: S1: liquid is transported into the disinfection box (1) through the liquid inlet pipe (38). When the liquid enters the disinfection box, it impacts the filter rack (3) and drives the filter rack (3) to rotate. When the filter rack (3) rotates, the shielding member (22) moves under the centrifugal force, thereby sealing and shielding the arc-shaped through hole on the filter rack (3). The sieve plate (5) blocks the particle impurities and collects them on the corresponding blades as the blades rotate. When the impact force of the liquid decreases, the shielding member (22) is reset. At this time, the impurities collected on the blades are collected in the filter rack (3); S2: The liquid impacts the arc plate (23) through the impact tube (6), and the impact causes the lifting frame (20) to move downward, which drives the rack (18) to move downward, and then drives the reflector (16) to adjust the reflection angle through the gear 1 (17). When the liquid flow rate is fast and the impact force is large, the rotation angle is larger; S3: The filter frame (3) rotates to drive the shaft frame (4) to rotate. The shaft frame (4) rotates to drive the shaft body (39) to rotate through the transmission structure (14). The shaft body (39) rotates to drive the gear ring seat 1 (7), the gear ring seat 3 (31), and the gear ring seat 2 (8). By changing the branch pipe through which the liquid passes, the rotation angle of the shaft frame (4) can be changed, thereby controlling whether the gear ring seat 1 (7) rotates; S4: The gear ring seat (7) rotates to drive the UV-LED lamp (9), the pusher (13), and the reflector (16) to rotate together. During the rotation process, the pusher (13) causes the round rod (10) to swing under the action of centrifugal force, thereby adjusting the angle of the UV-LED lamp (9). The magnitude of the centrifugal force is related to the magnitude of the impact force of the liquid, so that the adjustment magnitude of the angle of the UV-LED lamp (9) is coordinated with the flow rate of the liquid, and a disinfection is performed by utilizing the coordination between the UV-LED lamp (9) and the reflector (16); S5: When the liquid continues to move downward through the gear ring seat 1 (7), the liquid at the center position can directly enter the gathering pipe (27), and enter the gear ring seat 3 (31) through the connecting pipe (28), and then flow out through the mixing pipe (33). At this time, the liquid flowing out contacts the edge of the liquid, and the center liquid is transported to the edge position. When the gear ring seat 3 (31) rotates, the mixing pipe (33) is driven to rotate together. At this time, the squeezing roller (36) rotates with the cooperation of the gear ring (32) and the gear 3 (37). During the rotation of the squeezing roller (36), the mixing pipe (33) is intermittently squeezed, thereby changing the impact force of the liquid when it flows out through the mixing pipe (33), so that the liquid at the center position is fully transported to the edge of the liquid and the inner position of the edge; S6: The liquid continues to flow and undergoes secondary disinfection through the UV-LED lamp (9) on the second gear ring seat (8), and finally flows out of the disinfection box (1) through the external tube.
