Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an ultraviolet disinfection device. Background Technology

[0002] Hospitals primarily install ultraviolet (UV) disinfection devices in areas requiring strict air or surface disinfection, such as high-risk areas like operating rooms, treatment rooms, laboratories, isolation wards, fever clinics, and medical waste disposal rooms, as well as some instrument storage or cleaning areas. The UV lamps used in these devices are devices that emit ultraviolet light, a physical method of sterilization. Their wavelengths range from 10-400 nm. However, prolonged exposure can cause eye discomfort and, in severe cases, burns.

[0003] Currently, ultraviolet (UV) lamps are often installed on the ceiling of rooms to achieve overall room disinfection. For example, patent application CN201921244560.6 discloses a safe UV disinfection device, which includes a housing, a UV lamp, a junction box, and a controller. The advantage of this invention is that when the UV lamp is activated, the controller programs and controls the piston rod of the hydraulic cylinder to move up and down. This causes the drive gear, under the action of the connecting rod, to rotate the gear plate. The gear plate then rotates the UV lamp and the reflector plate on the mounting plate, thereby increasing the height of the UV lamp and widening its irradiation angle. The UV light generated by the lamp is then reflected by the reflector plate to the surrounding area of ​​the room, reducing the area of ​​blind spots and improving the disinfection effect. Simultaneously, when the UV lamp is turned off, the controller rotates the reflector plate and the UV lamp, with the reflector plate facing inwards, enclosing the UV lamp between the reflector plate and the housing, preventing the UV lamp from being struck by thrown objects.

[0004] However, because the ultraviolet lamp light source is relatively stable, it will continue to irradiate once turned on, so nurses, doctors, and even patients who accidentally enter the room may not realize that the ultraviolet lamp has been turned on, which can lead to excessive exposure and burns.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the ultraviolet disinfection device according to an embodiment of the present invention includes a housing 100, a partition plate, ultraviolet lamps 200, and a shielding assembly. The housing 100 is connected to the room. The partition plate is connected in parallel and spaced within the housing 100 to form a plurality of mounting slots 120. The ultraviolet lamps 200 are respectively connected to each mounting slot 120. The shielding assembly includes a fixed baffle 310, a pushing mechanism 320, and a movable baffle 330. The fixed baffle 310 is connected to the light-transmitting opening 130 of the housing 100. The movable baffle 330 is movably connected to the fixed baffle 310. The pushing mechanism 320 is drivenly connected to the movable baffle 330.

[0032] In actual use, the fixed baffle 310, together with the pushing mechanism 320, drives the movable baffle 330 to block the ultraviolet lamp tube 200, so that the irradiation of the ultraviolet lamp tube 200 is in a discontinuous state. At the same time, the light and shadow changes brought about by the movable baffle 330 will be very obvious, so that the intruder can easily feel that the ultraviolet light source is on. This can remind the intruder that ultraviolet disinfection has started in the room, prompting the intruder to leave as soon as possible or turn off the ultraviolet disinfection device as soon as possible, and prevent the intruder from being exposed to ultraviolet radiation for a long time.

[0033] Specifically, the partition is made of mirrored material. The mirrored partition allows most of the light emitted by the ultraviolet lamp tube 200 in the horizontal direction to be reflected and emitted through the light-transmitting opening 130, thereby enhancing the effect of ultraviolet disinfection.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the upper part of the fixed baffle 310 is provided with a first light-transmitting hole 311 corresponding to the ultraviolet lamp tube 200;

[0035] The movable baffle 330 is provided with second light-transmitting holes 331 at intervals.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: the first light-transmitting hole 311 is uniformly arrayed on the fixed baffle 310;

[0037] The distance between adjacent first light-transmitting holes 311 is greater than the width of the first light-transmitting hole 311.

[0038] In some specific embodiments of this utility model, it may also have the following additional technical features: the second light-transmitting holes 331 are uniformly arrayed on the movable baffle 330;

[0039] The distance between adjacent second light-transmitting holes 331 is greater than the width of the second light-transmitting hole 331.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: the shape of the first light-transmitting hole 311 is the same as that of the second light-transmitting hole 331.

[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: a sliding groove 312 is connected to the side of the fixed baffle 310 facing the ultraviolet lamp tube 200, and the movable baffle 330 is slidably connected in the sliding groove 312.

[0042] In some specific embodiments of this utility model, it may also have the following additional technical features: the pushing mechanism 320 is an electric telescopic rod, and the rod body of the electric telescopic rod is connected to the movable baffle 330.

[0043] By driving the movable baffle 330 along the length of the slide groove 312 of the fixed baffle 310 via the pushing mechanism 320, when the first light-transmitting hole 311 and the second light-transmitting hole 331 are completely aligned, the light from the ultraviolet lamp 200 is unobstructed and can pass through the second light-transmitting hole 331 and the first light-transmitting hole 311 in sequence to illuminate the room. However, when the first light-transmitting hole 311 and the second light-transmitting hole 331 are only partially aligned until they are completely misaligned, the light from the ultraviolet lamp 200 is gradually blocked and is completely blocked after the first light-transmitting hole 311 and the second light-transmitting hole 331 are completely misaligned, thus completely blocking the light from the ultraviolet lamp 200. During operation, the electric telescopic rod reciprocates, causing the first light-transmitting hole 311 and the second light-transmitting hole 331 to constantly change between alignment and misalignment, thereby creating a distinct light and shadow effect that can be seen by those who accidentally enter.

[0044] In some specific embodiments of this utility model, it may also have the following additional technical features: the ultraviolet disinfection device also includes a ceiling mounting bracket 410 installed on the ceiling and a lifting component, the lifting component being connected to the ceiling mounting bracket 410 and drivenly connected to the housing 100.

[0045] In some specific embodiments of this utility model, it may also have the following additional technical features: the lifting assembly includes a lifting drive 421, a take-up reel 422 and a suspension line 423. The lifting drive 421 is mounted on the ceiling mounting bracket 410, the take-up reel 422 is fixedly mounted on the output end of the lifting drive 421, and the two ends of the suspension line 423 are respectively fixedly connected to the take-up reel 422 and the outer casing 100.

[0046] Furthermore, the ultraviolet lamp 200 is lowered by the lifting component to carry out ultraviolet disinfection. The ultraviolet lamp 200 at different heights allows unauthorized intruders to more clearly perceive whether the room is being disinfected with ultraviolet light.

[0047] Specifically, the lifting drive component 421 is a drive motor. To further improve stability during the lifting process, an isosceles triangle 424 is connected between the suspension line 423 and the outer casing 100. The suspension line 423 is connected to one end of the isosceles triangle 424, and the remaining two ends of the isosceles triangle 424 are connected to the two ends of the top of the outer casing 100 via steel wires. Through the above design, the presence of the isosceles triangle 424 during the lifting process ensures that the outer casing 100 remains essentially horizontal, thus maintaining a stable lifting process.

[0048] In some specific embodiments of this utility model, it may also have the following additional technical features: an LED warning light 140 is connected to the outer casing 100, and a light intensity sensor 150 is connected to the inner wall of the outer casing 100 on the side away from the light-transmitting opening 130. The LED warning light 140 is electrically connected to the light intensity sensor 150. When the light intensity sensor 150 detects that the light intensity of the ultraviolet lamp 200 exceeds a threshold, it triggers the LED warning light 140, causing the LED warning light 140 to emit light. Preferably, the LED warning light 140 is a red LED warning light 140. The red warning light can more clearly make the intruder aware that the ultraviolet lamp 200 is working, and at the same time urge the intruder to turn off the ultraviolet disinfection device or leave the current room.

[0049] It should be noted that the UV lamp 200, electric telescopic pole, drive motor, light intensity sensor 150 and LED warning light 140 are all commonly used technical solutions in the prior art. They can all be obtained by consulting reference books and purchasing them on the market according to the actual needs and parameters. Their specific structure and principle will not be described in detail here.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
