11 is a cross-sectional view of the water purifying apparatus according to an embodiment of the present invention.

Referring to FIG. 11, the water purification device 300 includes a reservoir 310 and a sterilization module 320.

According to an embodiment of the present invention, the water purification device 300 sterilizes the water stored in the reservoir 310 by the sterilization module 320, thereby treating the water with water.

According to an embodiment of the present invention, the water is stored in the reservoir 310. Although not shown in FIG. 11, the water tank 310 has an inlet through which water is introduced from the outside and an outlet through which purified water is discharged to the outside.

According to an embodiment of the present invention, the sterilization module 320 is installed to penetrate one surface of the reservoir 310. Here, the sterilization module 320 is one of the sterilization modules of FIGS. 1 to 10. Detailed description of the configuration of the sterilization module 320 will be described with reference to FIGS. 1 to 10.

Referring to FIG. 11, the sterilization module 320 is installed to penetrate the upper surface of the reservoir 310. The lower part of the sterilization module 320 is located inside the reservoir 310, and the upper part of the sterilization module 320 is located outside the reservoir 310. In detail, a part of the body fixing part 113 and the main body 110 located below the body fixing part 113 is located in the reservoir 310. In addition, the portion of the main body 110, the upper portion of the body fixing portion 113 and the outer holder 170 is located outside the reservoir 310. Therefore, the inner wall of the reservoir 310 is in contact with the upper surface of the body fixing portion 113. In addition, the outer wall of the reservoir 310 is in contact with the lower surface of the outer holder 170.

At this time, by the outer sealing material 182 located between the upper surface of the body fixing portion 113 and the inner wall of the reservoir 310, the waterproof effect of the sterilization module 320 is improved.

According to an embodiment of the present invention, the sterilization module 320 irradiates ultraviolet rays to the surface of the water stored in the reservoir 310. The water stored in the reservoir 310 is purified by the sterilization effect of ultraviolet rays emitted from the sterilization module 320.
