Please refer to FIG. 3, which is a perspective view of the third embodiment of the ultraviolet sterilization device of the present invention. In some examples, the ultraviolet sterilization device 10 may further include an infrared detection unit 22, which is electrically connected to the control unit 16, and the infrared detection unit 22 is used to detect whether there are people in the sterilization range of the ultraviolet sterilization device 10 , The control unit 16 triggers the warning unit 18 to generate a corresponding warning signal according to the received detection result and indication signal. In the example in FIG. 3, there are a total of four infrared detection units 22, which are distributed in different directions, and can detect whether there are people in the sterilization range of the ultraviolet sterilization device 10 from different directions. For example, when the detection result of the infrared detection unit 22 is that there is no one and the indication signal is a sterilization start signal, the warning signal is a red light flashing. If the ultraviolet sterilization device 10 detects that someone enters the sterilization range of the ultraviolet sterilization device 10 during the sterilization process, the ultraviolet generation unit 14 stops the sterilization, and the warning unit generates 18 a fourth warning signal (which can be an orange light flashing) to remind the warning The person leaves; when the person leaves, the ultraviolet sterilization device 10 returns to the sterilization state, and the warning signal is flashing red. When the indicator signal is a sterilization start signal, and the infrared detection unit 22 detects that someone needs to be sterilized, the warning unit 18 generates a fourth warning signal (which can be an orange light flashing) to remind the warning personnel to leave. After a period of time, ultraviolet light sterilizes The device 10 enters the sterilization state, and the warning signal is flashing red.

In some implementation examples, the ultraviolet sterilization device 10 may further include a timer 26. The manual switch 24 is electrically connected to the control unit 16 for generating an instruction signal and outputting to the control unit 16. After the instruction signal received by the control unit 16 is a sterilization start signal, the timer 26 is triggered to start counting for a set time. After the timer 26 completes timing, a start signal is generated to instruct the control unit 16 to start the ultraviolet generation unit 14 to generate ultraviolet rays for sterilization, and control the warning The unit 18 generates a first warning signal (such as a red light flashing). The set time is 30 to 60 seconds or other reasonable time. The specific setting time can be determined comprehensively according to the actual situation. In one embodiment, after the control unit 16 receives the sterilization start signal, in addition to triggering the timer to start timing, it can also control the warning unit 18 to generate a third warning signal (such as orange flashing) to prompt the indoor personnel to leave as soon as possible.

The timer 26 can also be used in conjunction with the infrared detection unit 22. When the indication signal is a sterilization start signal and the infrared detection unit 22 detects a person, the warning unit 18 generates a third warning signal (such as a flashing orange light) to remind the person Leave. After the timer 26 finishes timing and the infrared detection unit 22 confirms that there is no one, the control unit 16 will activate the ultraviolet generation unit 14 to generate ultraviolet rays. The wire is sterilized, and the warning unit 18 is controlled to generate a first warning signal (such as a red light flashing). If the timer 26 finishes timing but the infrared detection unit 22 still detects a person, the control unit 16 will continue to delay the activation time of the ultraviolet generation unit 14, and the warning unit 18 will continue to generate a third warning signal (such as a flashing orange light) Prompt the staff to leave.

In some implementation examples, the timer 26 can also be used to set the sterilization time of the ultraviolet generating unit 14. Generally speaking, the sterilization time can be set to 30 minutes or more. The user or manager can adjust the sterilization time according to different actual conditions or preset the sterilization time corresponding to different situations. For example, if the space is seriously polluted, has not been sterilized for a long time, or the space is large, a longer sterilization time can be set. When the indication signal received by the control unit 16 is a sterilization start signal, the sterilization start signal is sent to the timer 26, and the timer 26 matches the preset according to the detection result of the infrared detection unit 22 and/or the detection result of the air quality detection unit. Set the sterilization time, start the ultraviolet generating unit 14 for sterilization, and the warning signal is flashing red. After the preset sterilization time, the ultraviolet generating unit 14 is turned off, and the warning signal is a steady green light.

In one embodiment, the fourth warning signal is set as a yellow warning light. Depending on the specific situation, the fourth warning signal can be further divided into a steady yellow light or a flashing yellow light.

For example, when the detection result of the air quality detection unit is that the air is good and the sterilization is over, the warning signal of the warning unit 18 is a steady green light. When the detection result of the air quality detection unit is that the air is bad, the warning signal of the warning unit 18 is yellow regardless of whether the sterilization is over. The light flashes to warn the manager to pay attention to the air quality condition and the cause of formation within the sterilization range of the ultraviolet sterilization device 10, and whether or not to arrange sterilization operations, etc.

In some implementation examples, the ultraviolet sterilization device 10 may further include a digital teaching module (not shown in the figure), which is electrically connected to the control unit 16.
