Furthermore, the circuit board 20 is a double-layer circuit board, the ultraviolet light emitting module 22 , the visible light emitting module 23 and the distance sensor 24 are arranged on the bottom circuit of the circuit board 20 , and the casing 10 is The bottom surface has bottom through holes 131 , 132 and 133 opposite to the ultraviolet light emitting module 22 , the visible light emitting module 23 and the distance sensor 24 ; the switch 28 , the charging port 291 and the charging indicator 292 are arranged on the bottom surface. The top circuit of the circuit board 20 is formed, and the top surface of the casing 10 has top through holes 141 , 142 and 143 opposite to the switch 28 , the charging port 291 and the charging indicator 292 .

Based on this structure, the folded state of the present invention is shown in [Fig. 1A] and [Fig. 1B], and the size of a credit card is very convenient to carry; then, the unfolded state is shown in [Fig. 2A], [Fig. 2B], [Fig. 3] [ 5], the article to be sterilized (such as a mask) is placed under the casing 10, and the switch 28 is pressed to let the ultraviolet light emitting module 22 irradiate the article with ultraviolet light for sterilization; The state of use is shown in [ FIG. 6 ], the casing 10 is directly placed on the object to be sterilized (eg cups), and several concentric concave grooves 11 on the bottom surface of the casing 10 help the casing 10 10, press the switch 28 to let the ultraviolet light emitting module 22 irradiate the ultraviolet light on the article for sterilization.

However, during the sterilization, the visible light emitting module 23 emits visible light (eg, blue light), so that the surrounding people know that the sterilization is currently being performed, so as to prevent the surrounding people from being harmed by ultraviolet light because they do not know that the sterilization is being performed. In addition, while sterilization is performed, there is at least one automatic shutdown sensing control element (distance sensor 24, angle sensor 25, timer 26 or a combination thereof) to perform the active safety sensing and control of the present invention; distance The sensor 24 senses whether there is an item within the set distance D of 10 cm, and automatically shuts down once there is no item within the set distance (for example, in a suspended state); the angle sensor 25 senses that the allowable tilt angle is within 75 degrees. In the horizontal setting state, it will automatically shut down; the timer 26 will automatically shut down when the set time is 1 minute.

Therefore, the folded state of the new type is only about the size of a credit card, which has the effect of being convenient to carry around and use; it also improves the safety of use through multiple safety mechanisms such as emitting visible light, sensing distance, sensing angle and timing. effect.

To sum up, the technical means disclosed in this new model do meet the new patent requirements such as "novelty", "progressiveness" and "availability for industrial use". Moral sense.
