Description

Technical Field

[0001] The invention relates to the technical field of sterilization and disinfection water tanks, in particular to a deep ultraviolet LED sterilization and disinfection water tank. Background Art

[0002] The quality of cleaning, disinfection and sterilization of surgical instruments is one of the key points in operating room management. Surgical instruments are usually cleaned in medical cleaning machines to ensure the cleaning quality. In order to avoid pathogens in the cleaning water, medical cleaning machines are usually equipped with ultraviolet sterilization tanks to disinfect pathogens in the water.

[0003] In order to ensure the sealing of the existing sterilization and disinfection water tanks, bolts are mostly used to fix the box body and the box cover. The LED ultraviolet lamp is fixedly installed inside for irradiation and sterilization. It is inconvenient to inspect and replace the LED ultraviolet lamp. The staff needs to use tools to disassemble and install multiple bolts to replace the LED ultraviolet lamp whose life has expired. It takes a long time, and the internal volume of the water tank is limited. It cannot be adjusted according to actual use needs, and its use is limited. Summary of the invention

[0004] The invention relates to a deep ultraviolet LED sterilization and disinfection water tank, which solves the problem that in order to ensure the sealing of the existing sterilization and disinfection water tank, a box body and a box cover are mostly fixed with bolts, and it is inconvenient to inspect and replace the internal LED ultraviolet lamp in the later stage. The staff needs to use tools to disassemble and assemble multiple bolts to replace the LED ultraviolet lamp whose life has expired, which is time-consuming. In addition, the internal volume of the water tank is limited, and the volume cannot be adjusted according to actual use requirements, so there are limitations in use.

[0005] In order to achieve the above-mentioned purpose, a deep ultraviolet LED sterilization and disinfection water tank is provided, which specifically includes: an upper box body, a middle box body, a lower box body, a positioning hoop, a box top cover, a rubber sealing ring, an LED deep ultraviolet lamp and a movable locking sleeve; the bottom of the upper box body is fixedly connected to the middle box body, and the bottom of the middle box body is fixedly connected to the lower box body; the outside of the lower box body is connected to the positioning hoop, and the positioning hoop is connected to the upper box body; the top of the upper box body is buckled with the box top cover, the inside of the box top cover is installed with a rubber sealing ring, and the bottom of the box top cover is installed with an LED deep ultraviolet lamp; the outside of the upper box body is covered with a movable locking sleeve, and the top of the movable locking sleeve is in contact with the bottom of the box top cover.

Water enters the water tank through the water inlet, and the LED deep ultraviolet lamp emits deep ultraviolet light to kill bacteria in the water. Then the water is discharged through the drain port. The upper box body can be adjusted up and down according to the required volume to change the distance between the upper box body and the lower box body. The upper box body drives the middle box body to retract and retract to change the internal volume of the water tank.

[0007] Furthermore, a vertical rod is arranged in a surrounding shape on the outside of the upper box body, and an ear plate is arranged in a surrounding shape on the outside of the lower box body. The ear plate is provided with a through hole inside, and the vertical rod passes through the through holes provided on the two ear plates.
