Description

Technical Field

[0001] This utility model relates to a partition curtain disinfection device, belonging to the field of disinfection equipment technology. Background Technology

[0002] Partition curtains are flexible partition devices commonly used in shopping malls, medical institutions, laboratories, and other places. They are mainly used to separate spaces, protect privacy, guide the flow of people, and create relatively independent work or rest areas. After frequent contact with people entering and exiting, partition curtains can accumulate germs, especially in hospital wards, surgical preparation areas, emergency rooms, and other places where partition curtains are often in close contact with patients and medical staff. Their surfaces are prone to accumulating droplets, dust, and microorganisms, thus becoming potential mediums for the spread of germs.

[0003] Currently, the disinfection of partition curtains mainly relies on manual methods. These include spraying disinfectant and wiping the surface. They can also be disassembled for cleaning or wiping. Manual disinfection not only requires dedicated personnel and regular disinfection, wasting manpower and resources, but also makes it difficult to thoroughly spray and wipe all areas, potentially leading to missed areas. Thorough disinfection requires disassembly, but this is time-consuming and affects usability, making it difficult to achieve high-frequency, comprehensive, and rapid disinfection. In high-risk infection scenarios, manual methods often fail to guarantee thoroughness and timeliness of disinfection.

[0004] Therefore, to solve the above problems, there is an urgent need for an automated, fully covered, and contactless disinfection technology that can be used while the partition curtain is suspended. Using a retractable array of ultraviolet lamps, disinfection is widely used for surface disinfection of items due to its advantages such as broad-spectrum sterilization, no chemical residue, and rapid disinfection speed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a partition curtain disinfection device, which solves the problem of low disinfection efficiency caused by relying on manual disinfection of partition curtains.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A partition curtain disinfection device includes:

[0008] The disinfection roller blind is composed of a flexible light-shielding layer and a flexible ultraviolet disinfection array layer. The inner surface of the light-shielding layer is provided with a reflective film, and the ultraviolet disinfection array layer has a uniformly distributed array of ultraviolet lamp beads. The inner and outer sides of the partition curtain are respectively provided with one of the disinfection roller blinds, and the ultraviolet disinfection array layer of each disinfection roller blind faces the partition curtain.

[0009] A synchronous winding device is fixed to the top of the partition curtain and synchronously winds up or lowers the two disinfection curtains.

[0010] Preferably, a pair of guide frames are vertically installed on both sides of the partition curtain, and two pairs of sliding grooves are provided on the guide frames along the vertical direction. The two sides of the disinfection roller curtain are inserted into the opposite sliding grooves and move up and down along the sliding grooves.

[0011] Preferably, a gravity bar is fixed to the bottom edge of the disinfection roller shutter.

[0012] Preferably, the synchronous winding device includes a winding box, two rotatably mounted inside the winding box, and a motor that synchronously drives the two rotatable rollers to rotate in opposite directions.

[0013] Preferably, the motor shaft is connected to one of the reels, and identical and meshing synchronous gears are fixed on both reels.

[0014] Preferably, human body sensors are provided on both the inner and outer sides of the winding box.

[0015] Preferably, proximity sensors for detecting the position of the end of the gravity rod are fixed at the top and bottom of the guide frame, respectively.

[0038] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0039] like Figure 1 , Figure 2 As shown, the disinfection equipment for this partition curtain 1 includes two disinfection roller blinds 2 installed on the inner and outer sides of the partition curtain 1, and a synchronous winding device 3 that synchronously winds up or lowers the two disinfection roller blinds 2.

[0040] like Figures 3-4 As shown, the disinfection roller shutter 2 is composed of a flexible light-blocking layer 201 and a flexible ultraviolet disinfection array layer 202.

[0041] The flexible light-shielding layer 201 uses PET, ETFE, or FEP film, or woven fabric with PVC or TPU coating as the roller blind substrate, and an aluminum layer is plated on it as a reflective film to achieve the effects of light shading and reflection.

[0042] The ultraviolet disinfection array layer 202 comprises an array of ultraviolet lamp beads fixed to the inner surface of the light-shielding layer 201 and flexible wires supplying power to the ultraviolet lamp beads array. The wires of the ultraviolet lamp beads array are covered by an ETFE film, which has good ultraviolet light transmittance, thus reducing the impact on the disinfection effect. The ultraviolet disinfection array layer 202 faces the partition curtain 1 for ultraviolet light irradiation disinfection.

[0043] like Figure 4 As shown, the synchronous winding device 3 is fixed to the top of the partition curtain 1 and synchronously winds up or lowers the two disinfection curtains 2. It includes a winding box 301, two parallel rollers 302 rotatably mounted within the winding box 301 (one roller 302 is obscured), and a motor 303 that synchronously drives the two rollers 302 to rotate in opposite directions. The shaft of the motor 303 is connected to one of the rollers 302, and identical and meshing synchronous gears 304 are fixed on both rollers 302 (one synchronous gear 304 is obscured).

[0044] The disinfection roller shutter 2 is lowered manually by operating the synchronous winding device 3, and then the ultraviolet lamp array is manually turned on for ultraviolet disinfection. After the specified disinfection time, the ultraviolet lamp array is manually turned off, and the synchronous winding device 3 is operated to wind up the disinfection roller shutter 2, completing one disinfection cycle. Automated disinfection can also be achieved through the controller described below. The disinfection roller shutter 2 can comprehensively disinfect both sides of the entire partition curtain 1 with ultraviolet irradiation, providing more thorough disinfection, and is simple and convenient to operate.

[0045] like Figures 3-5 As shown, in some embodiments, a pair of guide frames 4 are vertically installed on both sides of the partition curtain 1. Two pairs of sliding grooves 401 are provided on the guide frames 4 along the vertical direction. The two sides of the disinfection roller curtain 2 are inserted into the opposite sliding grooves 401 and move up and down along the sliding grooves 401.

[0046] Due to airflow changes or human contact, the disinfection roller shutter 2 may move away from or closer to the partition curtain 1, resulting in uneven ultraviolet light distribution and light leakage. The guide frame 4, with its sliding groove 401, confines the two sides of the disinfection roller shutter 2 within its designated track, ensuring that the distance between the disinfection roller shutter 2 and the partition curtain 1 remains constant. This guarantees uniform ultraviolet light distribution when the ultraviolet lamp array irradiates the partition curtain 1. Furthermore, the guide frame 4 completely blocks light leakage from the sides of the disinfection roller shutter 2, enhancing safety for nearby personnel.

[0047] like Figures 1-4 As shown, in some embodiments, a gravity rod 5 is fixed to the bottom edge of the disinfection roller shutter 2. The disinfection roller shutter 2 is relatively light in weight and may get stuck when rolling up or down. Therefore, the gravity rod 5 can be used to pull the disinfection roller shutter 2 straight down, making the entire disinfection surface flatter and making rolling up and down smoother.

[0048] like Figures 1-6 As shown, in some embodiments, human body sensors 6 are respectively installed on the inner and outer sides of the winding box 301. Proximity sensors 7, which detect the position of the ends of the gravity rod 5, are fixed to the top and bottom of the guide frame 4. The human body sensors 6 (two on the inner and outer sides), the proximity sensors 7 (two on the upper part and two on the lower part of the guide frame 4), the motor 303 (sharing the same motor via a synchronous gear 304), and the ultraviolet lamp array (two sets on the inner and outer sides) are all connected to the controller. The controller is connected to a status indicator 8 (two sets on the inner and outer sides) installed on the winding box 301. The status indicator 8 includes a status indicator light and a horn. The controller is installed inside the control box 9, which is fixed to the synchronous winding device 3.

[0049] like Figure 6 The diagram shows the circuit diagram for automatic disinfection via a controller. The controller uses a commercially available microcontroller (MCU). The human body sensor 6 is a commercially available passive infrared sensor that detects the presence or movement of a human by detecting changes in infrared radiation emitted by the human body. The proximity sensor 7 is a commercially available infrared reflective proximity sensor that detects changes in the intensity of the reflected infrared light to determine if an object is approaching. The ultraviolet lamp array uses LEDs that emit UVC ultraviolet light with wavelengths between 200–280 nm. The status indicator uses red and green dual-color LEDs.

[0050] Automatic disinfection control steps:

[0051] Disinfection mode: Taking a UVC intensity of approximately 0.5 mW / cm² as an example, the interval disinfection time can be set via the controller. For example, disinfection for 60 seconds every 1 hour.

[0052] (1) When the disinfection time point is reached, the controller controls the motor 303 to rotate forward and synchronously lower the disinfection roller shutters 2 on both the inner and outer sides of the partition curtain 1, and controls the red and green dual-color LED indicator to display red.

[0053] (2) When the proximity sensor 7 below detects the gravity rod 5 of the disinfection roller shutter 2, the motor 303 is stopped, the disinfection roller shutter 2 is in place, the double-sided ultraviolet lamp array is turned on, and a countdown of 60 seconds begins to carry out ultraviolet disinfection.

[0054] (3) During ultraviolet disinfection, if the human body sensor 6 detects that a person is approaching, the controller will immediately control the speaker to emit a warning sound: "Disinfecting in progress, please pass through later!"

[0055] (4) After 60 seconds of disinfection, turn off the double-sided UV lamp array, and the controller controls the motor 303 to reverse and roll up the disinfection curtain 2. When the proximity sensor 7 above detects the gravity rod 5 of the disinfection curtain 2, the motor 303 stops and controls the red and green dual-color LED indicator to display green, thus completing this disinfection.

[0056] By arranging ultraviolet lamp arrays on both the inner and outer sides of the partition curtain 1 and controlling the irradiation time as required, the surface of the partition curtain 1 can be efficiently, uniformly and comprehensively sterilized and disinfected without affecting its normal use, thereby reducing the risk of germ transmission and improving the hygiene and safety level of public places.

[0057] The disinfection curtain 2 can be rolled up and lowered synchronously by the synchronous winding device 3. During disinfection, the two opposing light-shielding layers 201 can block and reflect the ultraviolet light emitted by the ultraviolet lamp array on the opposite side. On the one hand, the reflective film of the light-shielding layer 201 makes full use of ultraviolet light for disinfection by multiple reflections. On the other hand, the light-shielding layers 201 block each other to prevent ultraviolet light from leaking to the opposite side and reduce the impact on nearby personnel.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
