Description

Technical Field

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

[0002] For liquid materials involved in surgical supplies, such as common disinfectants, cleaning liquids, or materials used in surgical dressings, during the production and preparation process of such liquid materials, it is necessary to disinfect and sterilize them. Commonly, for example, 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 usage requirements, especially for the disinfection effect at the middle position of the liquid. The disinfection effect is related to the irradiation time and distance. When the flow rate increases, the irradiation time is shortened, affecting the disinfection effect. For this reason, we propose a UV-LED disinfection device to solve the above problems. Summary of the Invention

[0024] In the above UV-LED disinfection device, the driving member includes a transmission structure, a second gear, and a shaft body. Three shaft bodies are rotatably installed on the disinfection box. One end of the filter screen frame and the three shaft bodies are hermetically and rotatably penetrated through the disinfection box. A transmission structure is sleeved on one end of the filter screen frame and the three shaft bodies outside the disinfection box. Second gears are installed on the three shaft bodies;

[0025] A one-way bearing is installed on the shaft body corresponding to the first toothed ring seat, and the one-way bearing is matched with the corresponding second gear.

[0026] A UV-LED disinfection method using the above disinfection device includes the following steps: S1: The liquid is transported into the disinfection box 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. At this time, the impurities collected on the blades will be collected into the filter screen frame;

[0027] S2: The liquid generates an impact on the arc plate through the impact pipe. This impact 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;

[0028] 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 toothed ring seat, the third toothed ring seat, and the second toothed 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 toothed ring seat rotates;

[0029] S4: The rotation of the first toothed ring seat drives the rotation of the UV-LED lamp, the pushing member, and the reflector together. During the rotation of the pushing member, the round rod swings 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 matched with the liquid flow rate. The UV-LED lamp and the reflector are used in cooperation for one-time disinfection;

[0030] S5: When the liquid continues to move downward through the first ring gear seat, the liquid at the central position can directly enter the converging pipe fitting, and then enter the third ring gear seat through the connecting pipe, and then flow out through the mixing pipe fitting. At this time, the outflowing liquid contacts the liquid edge, completing the transportation of the central liquid to the edge position. When the third ring gear seat rotates, it drives the mixing pipe fitting to rotate together. At this time, under the cooperation of the ring gear and the third gear, the extrusion roller rotates. During the rotation of the extrusion roller, an intermittent extrusion effect is exerted on the mixing pipe fitting, thereby changing the magnitude of the impact force when the liquid flows 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;

[0031] S6: The liquid continues to flow, is disinfected twice by the UV-LED lights on the second ring gear seat, and finally flows out of the disinfection box through the external pipe body.

[0032] Compared with the existing technology, the advantages of the present invention are as follows:

[0033] 1: Two groups of UV-LEDs arranged at different heights are used to disinfect the liquid multiple times. At the same time, a flow direction adjustment member and a liquid mixing member are arranged between the two groups of UV-LEDs to adjust the liquid after the first disinfection, adjust the liquid originally located in the middle position to the edge position, and then cooperate with the UV-LED below for re-disinfection to improve the disinfection effect.

[0034] 2: The reflection adjustment member is used to automatically adjust the angle of the reflector hood with the change of the magnitude 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.

[0035] 3: The filtering member is used 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 the impurities after use. At the same time, the filtering member can change the rotation direction by changing the flow direction when the liquid enters, thereby controlling the upper UV-LED to be in a rotating or stationary disinfection state.

[0067] Refer to Figures 1 - 20 , a UV-LED disinfection method, using the above-mentioned disinfection device, includes the following steps:

[0068] 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 screen frame 3 and drives the filter screen frame 3 to rotate. When the filter screen frame 3 rotates, the shielding member 22 moves under the action of centrifugal force, and then hermetically shields the arc-shaped through holes on the filter screen 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 screen frame 3;

[0069] S2: The liquid generates an impact on the arc plate 23 through the impact tube 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;

[0070] 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 toothed ring seat 7, the third toothed ring seat 31, and the second toothed ring 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 toothed ring seat 7 rotates;

[0071] S4: The rotation of the first toothed ring 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. Moreover, the magnitude of the centrifugal force is related to the magnitude of the liquid impact force, so that the adjustment magnitude of the angle of the UV-LED lamp 9 matches the liquid flow rate. The UV-LED lamp 9 and the reflector 16 are used in cooperation for primary disinfection;

[0072] S5: When the liquid continues to move downward through the first toothed ring seat 7, the liquid at the central position can directly enter the converging pipe fitting 27, and enter the third toothed ring 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 toothed ring seat 31 rotates, it drives the mixing pipe fitting 33 to rotate together. At this time, under the cooperation of the toothed ring 32 and the third gear 37, the pressing roller 36 rotates. During the rotation of the pressing roller 36, it has an intermittent pressing effect on the mixing pipe fitting 33, thereby changing the magnitude of the impact force of the liquid flowing out through the mixing pipe fitting 33, so that the liquid at the central position is fully transported to the edge and the position near the edge of the liquid;

[0073] S6: The liquid continues to flow, and is disinfected twice by the UV-LED lamp 9 on the second toothed ring seat 8, and finally flows out of the disinfection box 1 through an external pipe body.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

10. A UV-LED disinfection method, using the disinfection device as described in claim 9, characterized in that, It includes the following steps: S1: The liquid is conveyed into the disinfection tank (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 action of 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). This impact 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 reflection cover (16) to adjust the reflection angle through the first gear (17). The faster the liquid flow rate and the greater the impact force, the larger the rotation angle. 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 toothed ring seat (7), the third toothed ring seat (31), and the second toothed ring seat (8). By changing the branch pipes through which the liquid passes, the rotation angle of the shaft rod frame (4) can be changed, thereby controlling whether the first toothed ring seat (7) rotates. S4: The rotation of the first toothed ring seat (7) drives the UV-LED lamp (9), the pushing member (13), and the reflecting cover (16) to rotate together. During the rotation, the pushing member (13) causes the round rod (10) to swing under the action of centrifugal force, thereby adjusting the angle of the UV-LED lamp (9). Moreover, the magnitude of the centrifugal force is related to the magnitude of the liquid impact force, so that the adjustment of the angle of the UV-LED lamp (9) matches the liquid flow rate. The UV-LED lamp (9) and the reflecting cover (16) are used in cooperation for primary disinfection; S5: When the liquid continues to move downward through the first toothed ring seat (7), the liquid at the central position can directly enter the converging pipe fitting (27), and then enter the third toothed ring seat (31) through the connecting pipe (28), and then flow out through the mixing pipe fitting (33). At this time, the flowing liquid contacts the liquid edge, completing the transportation of the central liquid to the edge position. When the third toothed ring seat (31) rotates, it drives the mixing pipe fitting (33) to rotate together. At this time, under the cooperation of the toothed ring (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 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 toothed ring seat (8), and finally flows out of the disinfection tank (1) through an external pipe body.
