Abstract

The prevent invention provides a device with automatic sterilization and protective function, including a shell body that has a spreading mechanism to transmit a contact part. The contact part protrudes to the said shell body when the contact part is in the using position and when it is in the closing and opening position, it does not protrude to the said shell body. A controlling unit is set on the shell and connects to a sensing device and driving device. The said controlling unit has a timing unit, which connects to the said driving device to drive a sterilizing unit. Thereby, when user would like to operate related interface such as buttons of elevator, it can prevent user’s fingers from being contaminated by germs and can move to the using position by using the contact part of the prevent invention to click, touch and swipe the interface. After that, it can make the contact part move to the closing and opening position and the controlling unit can activate the driving device and timing unit to let the sterilizing unit sterilize the contact part. The way of sterilizing is to use ultraviolet to heat or spray on the sterilizing unit. The sterilizing process is carried out in the shell body and it will be automatically closed when it reaches the time value, which can prevent the sterilizing unit from destroying external environment and device and eliminate germs that is applied on of contact part to achieve the effectiveness of preventing epidemic and maintaining human health and safety.

Description

Device with automatic sterilization and protection function

The present invention provides a device with automatic sterilization and protection functions, especially a device that can operate an external environment interface through a contact part, and can be automatically sterilized when the contact part is folded, without affecting the external environment during the sterilization process , the device or its interface.

According to the press, in recent years, with the development of science and technology and changes in the environment, the mutation and evolution of viruses and bacteria have caused the bacteria to directly or indirectly infect various species through various channels according to their characteristics. Those who cannot produce antibodies immediately, or cannot resist, will lead to the high spread of the bacteria among the species. In addition, the current transportation technology is extremely developed, which promotes intensive contact between people or species in different countries, and further increases the spread of the bacteria around the world. If the bacteria are mutated again at this time, if there is no effective medicine to cure, it will cause a large-scale outbreak of the epidemic, and if the bacteria have a high mortality rate, the consequences will be unimaginable.

Although medical and pharmaceutical technology has also progressed, it is still not as good as the evolution of pathogenic bacteria. Therefore, today's infectious diseases, such as: influenza, bird flu, COVID-19, MERSCoV, SARS, etc., often have large-scale infections. Before the development of relevant therapeutic drugs is successful, the public can only strengthen epidemic prevention measures and improve their own resistance to avoid infection; and epidemic prevention measures still need to be adapted to the transmission route of germs. Among them, droplet infection and contact infection are more difficult to prevent. In addition to wearing masks, face coverings and washing hands frequently, Avoid touching the eyes, mouth and nose after contaminating the hands with germs. However, the hands are the most frequently used parts of the human body. They often need to touch or touch various supplies in daily life. germs, and contaminate the body or personal objects with hands, increasing the risk of infection; the operation of public appliances is still unavoidable in daily life, for example, buttons of elevators, screens of public payment machines, etc. Through finger selection, although users often use alternatives to replace their fingers due to the epidemic, such as ballpoint pens and keys, to operate public goods through other objects, however, the ends of ballpoint pens and keys have a certain sharpness. Clicking on it will damage public goods, or cause scratches on its screen and other interfaces. Although it can avoid direct contact with germs, it will cause damage to public goods or damage the appearance, so it is difficult to say that it is the correct way. , the bacteria will still adhere to the ballpoint pen and key. At this time, if the ballpoint pen or key is directly placed in the handbag or pocket without disinfection, it will also make the bacteria stick to the clothes or handbag, and it will still cause disease. Moreover, if it is attached to objects such as ball pens or keys, it cannot be disinfected immediately, so there is also a certain risk during the period of non-sterilization; and carrying objects such as alcohol or hypochlorous acid water with you will also cause cause inconvenience to users.

During the COVID-19 epidemic, public areas need to be disinfected regularly, but the disinfectant may enter the control circuit board through the gap of the pressing part, so many protective measures are to put plastic film on the elevator keys to avoid this problem; however, , the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and a research team from Princeton University and the University of California, Los Angeles (UCLA) conducted research to detect viruses left on surfaces in home or hospital settings The survival time of the virus, according to research, the new coronavirus survives the longest on plastic surfaces, 72 hours, followed by 48 hours on stainless steel surfaces; if it is on thick cardboard, it can survive for up to 24 hours; The time is shorter, and the virus cannot be detected for up to 4 hours; in the airborne particles of PM5.0 (5 microns), the new coronavirus can survive in the spray for up to 3 hours; therefore, the plastic film helps the survival of the virus, May Many units also put copper foil on the elevator buttons to reduce the survival time of the virus, but even so, for frequently used elevators, the protective effect is still limited.

Therefore, it is conventional to provide a UVC LED sterilizer, which mainly installs an ultraviolet light-emitting element on a body, so as to emit ultraviolet light for disinfection, so as to eliminate germs on clothes, mobile phones and other objects. However, UV light will destroy ordinary plastics. Material, if you use it to illuminate the elevator buttons, because most elevator buttons are still made of plastic, it will embrittle the elevator buttons, causing the button to be damaged. If the object is made of plastic, there is also a concern of damage, and the disinfection method will be the same as the above, so it must be carried separately, which also increases the inconvenience when using it.

In addition, related research shows that "dose (mJ/cm ² ) = UVC radiation intensity (mW/cm ² ) x time (Sec)", the higher the radiation intensity, the shorter the sterilization time, so if you want to achieve fast sterilization in seconds To this extent, the light intensity of UVC LED must be increased, and the lethal dose of UV for different microorganisms such as bacteria or viruses is also different. Taking SARS virus as an example, the light intensity is 90μW/cm ² (equivalent to 0.09mW/cm ² ) irradiation 30 minutes, or 1,800 seconds, can successfully destroy the virus; if the time is shortened to the level of 1.8 seconds, the intensity must be increased to 90,000μW/cm ² (ie 90mW/cm ² ) to achieve the same dose, which is obviously not effective for objects. And the human body is also very harmful, so carrying a UVC LED sterilizer with you is not a better epidemic prevention measure, but there is a fear of harming yourself.

Although the UVC LED sterilizer also has a lightweight design, as mentioned above, its intensity is insufficient, not as good as the intensity of sunlight at noon (0.055mw/cm ² ), and it takes about two years to eliminate the SARS virus. More than an hour, so there are still doubts about its applicability and anti-epidemic sterilization effect.

The prior art also provides an anti-epidemic pressing device. The main body is arranged in a column shape, and a cover is provided at the end. The cover is filled with sterilizing particles, such as chlorine dioxide, so that after the object is operated through the end of the body, The cover can be covered to form a seal between the cover and the main body through chlorine dioxide The space is sealed and sterilized; however, the cover cannot be removed and operated with one hand, so it is still inconvenient to use.
