The charging module 112 includes a battery 116 and a solar panel 117 , wherein the battery 116 is arranged in the lower area 102 , and the solar panel 117 is arranged in the casing 100 a. The sterilized liquid 106 is output through the output port 113 . The liquid 106 in this embodiment can be water or other liquids to be sterilized.

As shown in Figures 1 and 2, the portable liquid sterilizing device 100 has a one-piece shell 100a, which has a large capacity and is easy to carry, and is suitable for disaster relief personnel to use during emergency relief. Wherein, the casing 100 a and the solar panel 117 can be integrated into one body, and when the voltage of the battery 116 is insufficient, the solar panel 117 can convert light energy into electrical energy to charge the battery 116 .

On the other hand, the display panel 115 may also display indicator lights L2 (for example, LEDs) such as system standby or system normal operation. For example, when the system is in standby mode, the indicator light L2 is blue. When the system is working, the liquid flow is detected to start sterilization. At this time, the indicator light L2 is red and blue at the same time.

Please refer to FIG. 3 . FIG. 3 shows a schematic cross-sectional view of an ultraviolet treatment unit 110 adopting a double-flow tube structure.

The ultraviolet treatment unit 110 is, for example, a double-flow tube structure (or other types of multi-flow tube structure), one end of which is the inlet In, and the other end is the outlet Out. The inlet In and the outlet Out are located on the same side (such as the bottom side), and the inlet A U-shaped channel 121 is formed between In and the outlet Out. A sensing module (not shown in the figure, such as a flow meter) is provided in the double-flow pipe structure. When the liquid 106 enters the U-shaped channel 121 through the inlet In, the sensing module senses the flow of the liquid to activate the ultraviolet light emitting element 122 to emit deep Ultraviolet light, and sterilize the liquid 106 with deep ultraviolet light. In this embodiment, one side of the double-flow tube structure (the side opposite to the inlet In and the outlet Out, such as the top side) is provided with at least one ultraviolet light emitting element 122 and a light source detection module 124, and the light source detection module 124 is used By sensing the light intensity of the ultraviolet rays, the sterilizing ability of the portable liquid sterilizing device 100 can be known, and use information can be provided (for example, through the display panel 115 ) to the user.

In one embodiment, when only air is in the U-shaped channel 121 (no liquid 106 passes through), there is no impurity in the U-shaped channel 121 to absorb the ultraviolet light, so the light intensity of the ultraviolet light detected by the light source detection module 124 can be up to 100%; when the liquid 106 with low turbidity passes through, the impurities in the U-shaped channel 121 absorb less ultraviolet light at this time, so the light intensity of the ultraviolet light detected by the light source detection module 124 is about 80-85%; when the turbidity When the liquid 106 with high density passes through, impurities in the U-shaped channel 121 absorb more ultraviolet light at this time, so the light intensity of ultraviolet light detected by the light source detection module 124 is about 60-35%. At the same time, when the system detects that the liquid 106 with high turbidity passes through, the sterilizing ability of the portable liquid sterilizing device 100 can be improved by increasing the light intensity of the ultraviolet light, or a warning signal can be sent to the user (for example, with a bee beeper sounds), notifying the water quality is poor.

Please refer to FIG. 4 , which shows a schematic circuit diagram of the voltage detection module 114 . The voltage detection module 114 is used to detect the voltage of the battery 116, and can notify the user through the detection result when the voltage of the battery 116 is insufficient. The voltage detection module 114 includes a comparator 118. The comparator 118 has an input terminal voltage Va, a detection terminal voltage Vb, and an output terminal voltage Vc. The terminal voltage Vb is, for example, connected to a battery voltage, and the battery voltage is measured by voltage division, wherein the output terminal voltage Vc corresponds to the difference between the input terminal voltage Va and the detection terminal voltage Vb. For example, when the voltage of the battery 116 is lower than the system set voltage and the output terminal voltage Vc is a negative value, at this time, the voltage detection module 114 will activate an indicator light or a buzzer to generate a warning signal to inform the user that the current battery voltage is insufficient . On the contrary, when the battery voltage is higher than the system setting voltage, the output terminal voltage Vc is a positive value, indicating that the battery voltage is normal, and a light signal can be displayed to inform the user.

The portable liquid sterilizing device of the above embodiment of the invention has an ultraviolet treatment unit to sterilize the liquid, and has a charging module to charge and supply power to the battery of the portable liquid sterilizing device. When the battery voltage is insufficient, The solar panel converts light energy into electrical energy to provide power to charge the battery. In this way, the portable liquid sterilizing device of this embodiment can quickly connect the water pipe to the joint in response to emergency relief, and the external liquid enters the accommodating cavity, and Impurities in water are filtered and sterilized to improve timeliness. In another embodiment, the liquid can also be directly poured into the accommodating cavity through an opening without an external water pipe.
