Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical disinfection technology, specifically relating to a public keyboard disinfection device. Background Technology
[0002] In modern hospital environments, computer keyboards, as input devices frequently used by medical staff and patients, are generally shared and insufficiently disinfected. Especially in high-traffic areas such as emergency rooms, wards, and outpatient clinics, keyboard surfaces easily accumulate various pathogens, including bacteria and viruses, becoming potential vectors for cross-infection. Traditional manual disinfection methods (such as alcohol wiping) rely on manual operation, which is often difficult to perform regularly due to busy schedules and limited time for medical staff, resulting in inconsistent disinfection effectiveness. Furthermore, some keyboards have complex structures, making it difficult to thoroughly clean crevices and keycap gaps, further increasing the risk of pathogen residue. During flu season or epidemics, inadequately disinfected keyboards may accelerate the spread of pathogens, threatening the health of both medical staff and patients. Currently, there is a lack of efficient, convenient keyboard disinfection products suitable for hospital environments on the market. Therefore, there is an urgent need for a solution that can automate and quickly disinfect keyboards to reduce the risk of cross-infection and improve hospital infection control. Utility Model Content
[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one aspect of the present invention is to provide a public keyboard disinfection device, which includes a main frame, keyboard slots, an ultraviolet disinfection lamp and a motor. The main frame is a hollow cylindrical structure with a motor on one side. There are two keyboard slots, which are symmetrically arranged at both ends of the outer side of the main frame. The ultraviolet disinfection lamp is arranged on the outer side of the main frame and between the two keyboard slots.
[0004] Preferably, the main frame includes an antibacterial plastic mold roller shaft and an antibacterial plastic mold roller. The antibacterial plastic mold roller shaft is disposed inside the cylindrical structure of the main frame. One end of the antibacterial plastic mold roller shaft is fixedly connected to the output shaft of the motor, and the antibacterial plastic mold roller is slidably connected to the antibacterial plastic mold roller shaft.
[0005] Preferably, the main frame further includes a dust cover, which is disposed at the other end of the main frame opposite to the motor, and the dust cover is movably connected to the main frame.
[0006] Preferably, the main frame further includes an antibacterial plastic film outlet, which is horizontally positioned above the ultraviolet disinfection lamp.
[0007] Preferably, the main frame further includes a sliding knife, which is movably connected to the antibacterial plastic film outlet.
[0008] Preferably, the main frame is a metal structure.
[0009] Preferably, the keyboard slot includes a keyboard card, a magnetic block, and an anti-slip pad. The magnetic block is disposed at the connection end between the keyboard card and the main frame. The keyboard card is magnetically connected to the main frame through the magnetic block. The anti-slip pad is fixed on the side where the keyboard card is movably connected to the keyboard.
[0010] Preferably, the motor includes an antibacterial plastic mold roller shaft switch and an ultraviolet disinfection lamp switch, which are located near the ultraviolet disinfection lamp on the motor.
[0011] The beneficial effects of this utility model are as follows:
[0012] Long-lasting antibacterial protection: The antibacterial plastic film forms a durable protective layer on the keyboard surface, inhibiting the growth of bacteria and viruses, reducing microbial contamination during daily use, and ensuring a stable and continuous protective effect through regular replacement.
[0013] Highly efficient and deep disinfection: Ultraviolet disinfection technology can quickly inactivate a variety of pathogenic microorganisms (such as bacteria, viruses and fungi), making up for the shortcomings of traditional cleaning methods. It is especially suitable for hard-to-clean areas such as keyboard crevices, improving the overall hygiene level.
[0014] Dual protection system: The antibacterial film and ultraviolet light work together to form a multi-layered protection mechanism of "physical barrier + active disinfection", which significantly reduces the risk of cross-infection and is suitable for public places with high frequency of contact.
[0015] Convenient and highly adaptable: The product structure is compatible with various keyboards, and it is easy to operate. It can be widely used in densely populated places such as hospitals, schools, and public transportation to improve the hygiene and safety of public facilities.
[0016] Social health benefits: By optimizing keyboard hygiene management in public environments, the spread of diseases can be effectively reduced, user health can be protected, and the overall level of public health can be improved. It takes into account both practicality and innovation, and provides an efficient and reliable solution for the hygiene management of public keyboards.
[0017] Additional aspects and advantages of this invention will become apparent from the description which follows, or may be learned by practice of this invention. Attached Figure Description
