Description

Technical Field

[0001] The present disclosure generally relates to a disinfection device. More specifically, the present disclosure particularly relates to an ultraviolet disinfection device. Background Art

[0002] Ensuring adequate levels of disinfection as a means of limiting contamination, pathogen spread, and disease has proven to be a considerable challenge. This has become even more evident as viral infections have transitioned from local outbreaks to global pandemics.

[0003] It is instructive to study how viral diseases spread as a new indicator of the overall problem, and to help determine what steps can be taken to limit that spread. Like many viruses and infectious diseases, viral infections spread primarily through person-to-person interaction, both through close proximity and through contaminated objects. Droplets from sneezes and coughs can spread the virus between people because people are in close proximity to one another, and frequently touched surfaces can similarly contribute to transmission if they become contaminated with droplets containing the virus. To reduce transmission, steps must be taken to reduce the amount of live airborne and surface viruses that can be transmitted. Frequent handwashing and wiping down of surfaces can help, but their effectiveness depends on individual vigilance. The issue of increased disinfection has risen in our collective consciousness since the global viral infection pandemic began, but the technology has other uses as well, not only to greatly improve the level of disinfection in our daily lives.

[0004] Irradiating surfaces with ultraviolet light is a common method of disinfection. However, the development of UVC radiation that can effectively disinfect target pathogens has provided new opportunities for disinfection involving human tissue. Public buildings such as shopping malls, office buildings, grocery stores, etc. typically have many common public touch points, such as door handles, door knobs, elevator buttons, etc. Most of the time, such common public touch points are touched by the user's bare hands. In some cases, the user may have a common cold, flu, viral infection, and / or some other illness. In some cases, the user may be asymptomatic but still contagious. When such a user touches a common public touch point such as a door handle, the user may inadvertently contaminate the touched surface. Such contamination may expose subsequent users who touch the same public touch point to the disease, thereby exposing subsequent users to the risk of contracting the disease.

[0005] Light switches, elevator call buttons, elevator panel buttons, security keypads, toilet flush switch buttons, ATM panel buttons are some examples of contact surfaces that are typical carriers of infectious diseases through indirect or direct contact. For example, influenza viruses can be transmitted through such indirect or direct contact.

[0006] Unfortunately, many potential contamination transfer vector features of healthcare facilities and public or public areas have not been adequately addressed. Electrical or electronic switches (such as light switches, elevator switches, etc.) in public areas such as offices, hotels, hospitals, etc. are often contaminated. When the switch or button is used, contaminants may be transferred from one user of the switch or button to another user at the contact surface of the switch or button. This contamination transmission vector is believed to contribute to the spread of a variety of infectious diseases. Therefore, an effective method is needed to keep the contact surface of the switch or button disinfected. Utility Model Content

[0007] An object of the present disclosure is to be able to reduce or eliminate transfer-related contamination from selected touch points, including but not limited to electrical switches and push button switches, such as ordinary light switches, elevator call buttons, elevator panel buttons, keyboards, touch pads, etc., in an efficient, effective and economical manner.

[0033] The following disclosure provides many different embodiments or examples for realizing the different features of the utility model. The specific examples of components and arrangements are described below to simplify the disclosure. Of course, these are merely examples and are not intended to be limiting. In addition, the disclosure may repeat reference numerals and / or letters in each example. This repetition is for the purpose of simplicity and clarity, and does not itself specify the relationship between the various embodiments and / or configurations discussed.

[0034] In addition, for ease of description, spatially relative terms such as "under", "below", "lower", "above", "upper", etc. may be used herein to describe the relationship of one component or feature to another component. As shown in the figures. In addition to the orientations depicted in the figures, the spatially relative terms are intended to cover different orientations of the device in use or operation.

[0035] refer to Figure 1 , which shows a schematic diagram of an illustrative example of an ultraviolet light disinfection device according to the present disclosure. The ultraviolet light disinfection device mainly consists of an ultraviolet light source (20) installed in a frame (30), a motion detection sensor (40) and a controller (50). The ultraviolet light disinfection device of the utility model is installed on or above an operating interface (10), such as a light switch, an elevator call button, or an elevator control panel, a security keyboard, an ATM panel button, a touch panel, etc. Electronic device.

[0036] An ultraviolet (UV) light source (20) is mounted in the frame (30) and is preferably located to provide coverage of a specific portion of the entire operating surface (11) of the operating interface (10). The ultraviolet (UV) light source (20) primarily emits UV or UV-C radiation to kill pathogens on the operating surface (11) of the operating interface (10). Other effective UV-C generators or bulbs may be used. As will be understood by those skilled in the art, the UV or UV-C generator or bulb may be an array of one or more light emitting diodes (LEDs) that emit UV or UV-C radiation.

[0037] The motion detection sensor (40) is used to detect any movement near the operation interface (10). As will be understood by those skilled in the art, passive infrared (PIR), microwave and dual-type motion detection sensors that detect any movement near the operation interface (10) can all be used in the ultraviolet disinfection device according to the present disclosure. When the ultraviolet (UV) light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the operation surface (11) of the operation interface (10), if the motion detection sensor (40) detects any movement of the user near the operation interface (10), the controller (50) will suspend the working mode of the ultraviolet (UV) light source (20) to protect the user. Alternatively, when the ultraviolet (UV) light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the operation surface (11) of the operation interface (10), if any user operation is performed on the operation interface (10), the controller (50) will also suspend the working mode of the ultraviolet (UV) light source (20) to protect the user.

[0038] After the user uses the operation interface (10), the controller (50) outputs an operation mode signal to the ultraviolet (UV) light source (20) for emitting UV or UV-C radiation to kill pathogens on the operation surface. According to the power of the ultraviolet (UV) light source (20) and the size of the disinfection area of ​​the operation interface (10), the predetermined irradiation time period of the ultraviolet (UV) light source (20) is pre-set in the controller (50). At the same time, the indicator light (52) is displayed as an operation mode in response to the operation mode signal output from the controller (50), for example, in orange. According to some embodiments of the present disclosure, when the ultraviolet (UV) light source (20) is not in the working mode, the frame (30) is located in the standby position; when in the working mode, the frame (30) moves to the working position, so that the ultraviolet (UV) light source (20) installed in the frame (30) is located to provide irradiation coverage for a specific portion of the entire operation surface (11) of the operation interface (10). In the operation mode. The movement of the frame (30) between the standby position and the working position is controlled manually by a user or by a working mode signal output by a controller (50). After the ultraviolet light source (20) emits UV or UV-C radiation for a predetermined time, the ultraviolet disinfection device completes the entire disinfection process of killing pathogens on the operating interface (10).

[0039] When the ultraviolet (UV) light source (20) is in an operation mode of emitting UV or UV-C radiation to kill pathogens on the operation surface (11) of the operation interface (10), if the motion detection sensor (40) detects that the user has any movement near the operation interface (10), the controller (50) will immediately output a pause signal to set the ultraviolet (UV) light source (20) to a pause mode to pause the ultraviolet (UV) light source (20) from emitting UV or UV-C radiation for a predetermined time, such as 30 seconds, to prevent the user from being harmed by UV or UV-C radiation, thereby protecting the user. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, such as red. According to some embodiments of the present disclosure, the frame (30) moves back to the standby position from the operation position in response to the pause signal output from the controller (50).

[0040] Alternatively, when the ultraviolet (UV) light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the operating surface (11) of the operating interface (10), if there is any user operation on the operating interface (10), the controller (50) will immediately output a pause signal to set the ultraviolet (UV) light source (20) to the pause mode to pause the ultraviolet (UV) light source (20) from emitting UV or UV-C radiation for a predetermined time, such as 30 seconds, to prevent the user from being harmed by UV or UV-C radiation, thereby protecting the user. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, such as red. According to some embodiments of the present disclosure, the frame (30) moves back to the standby position from the operating position in response to the pause signal output from the controller (50).

[0041] When the ultraviolet light source (20) is in the pause mode for a predetermined time (e.g., 30 seconds), and the motion detection sensor (40) does not detect any movement of the user near the operation interface (10) or the operation interface (10) is not operated, the controller (50) outputs another working mode signal to the ultraviolet (UV) light source (20), thereby resuming the ultraviolet (UV) light source (20) to emit UV or UV-C radiation light, so as to complete the entire disinfection process of killing pathogens on the operation surface (11) of the operation interface (10).

[0042] Optionally, the ultraviolet disinfection device of the utility model further comprises a test button (60) located on the operation interface (10). During testing, an engineer can activate the ultraviolet (UV) light source (20) to emit UV or UV-C radiation light through the test button (60) to kill pathogens on the operation surface (11) of the operation interface (10), thereby ensuring that all aspects of the ultraviolet disinfection device function normally.

[0043] Reference Figure 2A , Figure 2B , Figure 2C and Figure 2D , are perspective views of illustrative examples of an ultraviolet disinfection device according to the present disclosure, which is used in standby mode and operating mode of an elevator call button and an elevator control panel, respectively. In these embodiments, the elevator call button and the elevator control panel are as shown Figure 1 In these embodiments according to the present invention, as shown in the operation interface (10). Figure 2A and Figure 2C As shown, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located in the same plane as the elevator call button (210) or the elevator control panel (220). When the ultraviolet (UV) light source (20) is in the working mode, in response to the working mode signal output by the controller (50), the frame (30) moves out to the working position, so that the ultraviolet (UV) light source (20) is in the working mode. The UV light source (20) installed in the frame (30) is located to provide coverage illumination to the entire button portion (211) of the elevator call button (210) or a specific portion of the button portion (221) of the control panel (220).

[0044] like Figure 2B and Figure 2D As shown, an ultraviolet (UV) light source (20) is mounted in a frame (30) of an elongated housing, and the frame (30) is mounted on the entire elevator call button (210) or the entire elevator control panel (220) to provide ultraviolet light coverage of the entire button portion (211, 221). An indicator light (52) is disposed on the elevator call button (210) or the elevator control panel (220), preferably on the outer surface of the frame (30). A motion detection sensor (40) is disposed on or inside the frame (30) together with the ultraviolet (UV) light source (20), or on the elevator call button (210) or the elevator control panel (220) outside the frame (30), as long as the motion detection sensor (40) can detect any movement near the elevator call button (210) or the elevator control panel (220) within the coverage of UV or UV-C radiation emitted from the ultraviolet (UV) light source (20).

[0045] When a user presses an elevator call button (210) or an elevator control panel (220), the controller (50) outputs an operating mode signal to the ultraviolet (UV) light source (20), so that the ultraviolet (UV) light source (20) emits UV or UV-C radiation to kill pathogens on the button portion (211, 221) of the elevator call button (210) or the elevator control panel (320) within a predetermined time period preset in the controller (50). At the same time, the indicator light (52) displays an operating mode in response to the operating mode signal output from the controller (50), for example, in orange. After the ultraviolet light source (20) emits UV or UV-C radiation for the predetermined time, the ultraviolet light disinfection device completes the entire disinfection process of irradiating pathogens on the button portion (211, 221) of the elevator call button (210) or the elevator control panel (220).

[0046] During the operation mode of emitting UV or UV-C radiation by the ultraviolet (UV) light source (20), if the motion detection sensor (40) detects any movement of the user near the elevator call button (210) or the elevator control panel (220), the controller (50) will immediately output a pause signal to pause the ultraviolet (UV) light source (20) from emitting UV or UV-C radiation for a predetermined time, for example, 30 seconds. The pause mode can prevent the user from being harmed by UV or UV-C radiation. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, for example, red. After the ultraviolet (UV) light source (20) is in the pause mode for a predetermined time (e.g., 30 seconds), the motion detection sensor (40) does not detect any movement of the user near the elevator call button (210) or the elevator control panel (220), and the controller (50) outputs another working mode signal to the ultraviolet light source (20), thereby resuming the ultraviolet light source (20) to emit UV or UV-C radiation, thereby completing the entire process of killing pathogens on the button portion (211, 221) of the elevator call button (210) or the elevator control panel (220). Alternatively, when the ultraviolet (UV) light source (20) is in the working mode, emitting UV or UV-C radiation to kill pathogens on the button portion (211, 221) of the elevator call button (210) or the elevator control panel (220), when the elevator call button (210) or the elevator control panel (220) is operated by any user, the controller (50) will pause the working mode of the ultraviolet (UV) light source (20) to protect the user. When the ultraviolet (UV) light source (20) is in the pause mode for a predetermined time, such as 30 seconds, and the elevator call button (210) or the elevator control panel (220) is not operated by any user, the controller (50) outputs another working mode signal to the ultraviolet light source (20), so that the ultraviolet light source (20) resumes emitting UV or UV-C radiation, thereby completing the entire disinfection process of illuminating pathogens on the button portion (211, 221) of the elevator call button (210) or the elevator control panel (220).

[0047] See also Figure 3A and Figure 3B , is a perspective view of an illustrative example of an ultraviolet (UV) light disinfection device according to the present disclosure, the device being in standby mode and keyboard use in operating mode. In this embodiment, the keyboard is such as Figure 1 The operation interface (10) shown in FIG. Figure 3AAs shown, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located in the same plane as the keyboard (310). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) moves upward to the working position in response to the working mode signal output from the controller (50), so that the ultraviolet (UV) light source (20) installed in the frame (30) is located in a specific part that can provide light to cover the entire key portion (311) of the keyboard (310). The ultraviolet (UV) light source (20) installed in the frame (30) of the elongated housing is arranged at the upper end of the keyboard (310) and is located in the entire key portion (311) of the keyboard (310). The indicator light (52) is preferably arranged on the outer surface of the frame (30). The motion detection sensor (40) is located inside or on the frame (30), or on the keyboard (310) outside the frame (30), as long as the motion detection sensor (40) can detect any user's movement near the keyboard (310) within the coverage of the UV or UV-C radiation light emitted from the ultraviolet (UV) light source (20).

[0048] When the user uses the keyboard (310), the controller (50) outputs an operating mode signal to the ultraviolet (UV) light source (20), and within a predetermined time preset in the controller (50), the ultraviolet (UV) light source (20) emits UV or UV-C radiation to kill pathogens on the key portion (311). At the same time, the indicator light (52) responds to the operating mode signal output from the controller (50) and displays the operating mode, for example, in orange. After the ultraviolet light source (20) emits UV or UV-C radiation for a predetermined time, the ultraviolet light disinfection device completes the entire process of irradiating the pathogens on the key portion (311) of the keyboard (310).

[0049] During the operation mode of emitting UV or UV-C radiation, if the motion detection sensor (40) detects any movement of the user near the keyboard (310), the controller (50) immediately outputs a pause signal to cause the UV light source (20) to pause emitting UV or UV-C radiation for a predetermined time, such as 30 seconds, to prevent the user from being hurt. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, such as red. After the UV light source (20) is in the pause mode for a predetermined time (such as 30 seconds), the motion detection sensor (40) no longer detects any movement of the user near the keyboard (310), and the controller (50) outputs another operation mode signal to the UV light source (20), so that the UV light source (20) resumes emitting UV or UV-C radiation, thereby completing the entire disinfection process of the pathogens on the buttons (311) of the keyboard (310) illuminated by the UV light source (20).

[0050] In the embodiment of the present utility model, Figure 3A As shown, when the frame (30) is in the standby position, the frame (30) and the ultraviolet (UV) light source (20) are located in the same plane as the key portion (311) of the keyboard (310). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) moves upward to the working position in response to the working mode signal output from the controller (50), so that the upper end of the ultraviolet (UV) light source (20) is located to provide illumination covering the entire key portion (311) of the keyboard (310).

[0051] Alternatively, when the ultraviolet light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the entire key portion (311) of the keyboard (310), if there is any user operation on the keyboard (310), the controller (50) will pause the ultraviolet (UV) light source (20) in the operating mode, so that the ultraviolet (UV) light source (20) pauses emitting UV or UV-C radiation for a predetermined time to protect the user. When the ultraviolet light source (20) is in the pause mode after a predetermined time, such as 30 seconds, and the keyboard (310) is not operated by any user, the controller (50) outputs another operating mode signal to the ultraviolet light source (20), so that the ultraviolet light source (20) resumes emitting UV or UV-C radiation, and completes the entire disinfection process of the ultraviolet light source (20) illuminating the pathogens on the buttons (311) of the keyboard (310).

[0052] See also Figure 4A and Figure 4B, is a perspective view of an illustrative example of an ultraviolet (UV) light disinfection device according to the present disclosure, the device being in standby mode and in operation mode using a touch panel (410). In this embodiment, the touch panel (410) is as follows Figure 1 The operation interface (10) shown in FIG. Figure 4A As shown, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located in the same plane as the touch panel (410). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) moves upward to the working position in response to the working mode signal output by the controller (50), so that the ultraviolet (UV) light source (20) installed in the frame (30) is located in a specific part that can provide light to cover the entire touch panel (410). The ultraviolet (UV) light source (20) is installed in the frame (30) of the U-shaped housing, and the two ends of the U-shaped frame (30) are pivotally mounted on both sides of the touch panel (410). The indicator light (52) is preferably arranged on the outer surface of the frame (30) or on the touch panel (410). The motion detection sensor (40) is located either inside the frame (30) together with the ultraviolet (UV) light source (20) or on the frame (30), or on the touch panel (410) outside the frame (30), as long as the motion detection sensor (40) can detect any movement of the user near the touch panel (410) within the coverage of the UV or UV-C radiation emitted from the ultraviolet (UV) light source (20).

[0053] When the user uses the touch panel (410), the controller (50) outputs an operating mode signal to the ultraviolet (UV) light source (20), and within a predetermined time preset in the controller (50), the ultraviolet (UV) light source (20) emits UV or UV-C radiation to kill pathogens on the touch surface (411) of the touch panel (410). At the same time, the indicator light (52) responds to the operating mode signal output from the controller (50) and displays the operating mode, for example, in orange. After the ultraviolet light source (20) emits UV or UV-C radiation for a predetermined time, the ultraviolet disinfection device completes the entire process of irradiating the pathogens on the keys of the touch surface (411) of the touch panel (410).

[0054] During the operation mode of emitting UV or UV-C radiation, if the motion detection sensor (40) detects any movement of the user near the touch panel (410), the controller (50) immediately outputs a pause signal to cause the UV light source (20) to pause emitting UV or UV-C radiation for a predetermined time, such as 30 seconds, to prevent the user from being harmed. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, such as red. After the UV light source (20) is in the pause mode for a predetermined time (such as 30 seconds), the motion detection sensor (40) no longer detects any movement of the user near the touch panel (410), and the controller (50) outputs another operation mode signal to the UV light source (20), so that the UV light source (20) resumes emitting UV or UV-C radiation, thereby completing the entire disinfection process of the pathogens on the touch surface (411) of the touch panel (410) illuminated by the UV light source (20).

[0055] Alternatively, when the ultraviolet light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the touch panel (410), if there is any user operation on the touch panel (410), the controller (50) will pause the ultraviolet (UV) light source (20) in the operating mode, so that the ultraviolet (UV) light source (20) pauses emitting UV or UV-C radiation for a predetermined time to protect the user. When the ultraviolet light source (20) is in the pause mode after a predetermined time, for example, 30 seconds, and the keyboard (310) is not operated by any user, the controller (50) outputs another operating mode signal to the ultraviolet light source (20), so that the ultraviolet light source (20) resumes emitting UV or UV-C radiation, and completes the entire disinfection process of the ultraviolet light source (20) irradiating the pathogens on the touch surface (411) of the touch panel (410).

[0056] In the embodiment of the utility model, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located in the same plane as the touch panel (20). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) is pivoted upward to the working position in response to the working mode signal output from the controller (50), so that the upper end of the ultraviolet (UV) light source (20) is located at a specific part that can provide illumination to cover the entire touch surface (411) of the touch panel (410).

[0057] See also Figure 5A and Figure 5B , is a perspective view of an illustrative example of an ultraviolet (UV) light disinfection device according to the present disclosure, the device being in standby mode and in operation mode with a touch panel (510) in use. Figure 5A As shown, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located at the lower end of the touch panel (510). The frame (30) can slide in two grooves (520) located on both sides of the touch panel (510). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) responds to the working mode signal output by the controller (50) and slides upward toward the upper end of the touch panel (510) to the working position, so that the ultraviolet (UV) light source (20) installed in the frame (30) is located to provide light covering the entire touch panel (510). Alternatively, when the frame (30) is in the standby mode position, the frame (30) and the ultraviolet (UV) light source (20) are located at the upper end of the touch panel (510). The frame (30) can slide in two grooves (520) located on both sides of the touch panel (510). When the ultraviolet (UV) light source (20) is in the working mode, the frame (30) slides downward toward the lower end of the touch panel (510) to the working position in response to the working mode signal output by the controller (50), so that the ultraviolet (UV) light source (20) installed in the frame (30) is located to provide light covering the entire touch panel (510). The indicator light (52) is preferably arranged on the outer surface of the frame (30) or on the touch panel (510). The motion detection sensor (40) is either located inside the frame (30) together with the ultraviolet (UV) light source (20) or on the frame (30), or on the touch panel (510) outside the frame (30), as long as the motion detection sensor (40) can detect any user's movement near the touch panel (410) within the coverage range of the UV or UV-C radiation emitted from the ultraviolet (UV) light source (20).

[0058] When the user uses the touch panel (510), the controller (50) outputs an operating mode signal to the ultraviolet (UV) light source (20), and within a predetermined time preset in the controller (50), the ultraviolet (UV) light source (20) emits UV or UV-C radiation to kill pathogens on the touch surface (511) of the touch panel (510). At the same time, the indicator light (52) responds to the operating mode signal output from the controller (50) and displays the operating mode, for example, in orange. After the ultraviolet light source (20) emits UV or UV-C radiation for a predetermined time, the ultraviolet disinfection device completes the entire process of irradiating the pathogens on the keys of the touch surface (411) of the touch panel (410).

[0059] During the operation mode of emitting UV or UV-C radiation, if the motion detection sensor (40) detects any movement of the user near the touch panel (510), the controller (50) immediately outputs a pause signal to cause the UV light source (20) to pause emitting UV or UV-C radiation for a predetermined time, such as 30 seconds, to prevent the user from being harmed. At the same time, in response to the pause mode signal output from the controller (50), the indicator light (52) is displayed in a warning mode, such as red. After the UV light source (20) is in the pause mode for a predetermined time (such as 30 seconds), the motion detection sensor (40) no longer detects any movement of the user near the touch panel (510), and the controller (50) outputs another operation mode signal to the UV light source (20), so that the UV light source (20) resumes emitting UV or UV-C radiation, thereby completing the entire disinfection process of the pathogens on the touch surface (511) of the touch panel (510) illuminated by the UV light source (20).

[0060] Alternatively, when the ultraviolet light source (20) is in the working mode and emits UV or UV-C radiation to kill pathogens on the touch panel (510), if there is any user operation on the touch panel (510), the controller (50) will pause the ultraviolet (UV) light source (20) in the operating mode, so that the ultraviolet (UV) light source (20) pauses emitting UV or UV-C radiation for a predetermined time to protect the user. When the ultraviolet light source (20) is in the pause mode after a predetermined time, for example, 30 seconds, and the keyboard (310) is not operated by any user, the controller (50) outputs another operating mode signal to the ultraviolet light source (20), so that the ultraviolet light source (20) resumes emitting UV or UV-C radiation, and completes the entire disinfection process of the ultraviolet light source (20) irradiating the pathogens on the touch surface (511) of the touch panel (510).
