[0028] As Figure 5As shown, a connecting groove is arranged on the upper wall of the inner cavity of the sterilization box, the inner circumferential surface of the connecting groove has an internal thread matched with the external thread of the connecting convex ring 16, the bottom of the connecting groove has an annular water inlet corresponding to the annular water outlet 141, the middle of the bottom of the connecting groove has a convex mouth, the middle of the convex mouth has a water inlet channel, the convex mouth extends into the inner side of the water inlet ring 17 to be in close contact, and the water inlet channel is communicated with the first water passing channel 15. When the connecting convex ring 16 is screwed into the bottom of the connecting groove, the sealing ring in the first annular sealing groove 171 of the water inlet ring 17 abuts against the bottom of the connecting groove, so as to block the water inlet and the water inlet channel.

[0029] The bottom of the water spraying disc 1 has a bottom wall water outlet, the side of the water spraying disc 1 has a plurality of annularly and spacedly arranged side wall water outlets, the bottom wall water outlet is communicated with the first water passing cavity 14, the side wall water outlets are communicated with the bottom wall water outlet, the spray head 2 is connected to the bottom wall water outlet and the side wall water outlets, and the spraying range is as shown in Figure 7 .

[0030] Embodiment 2

[0031] As shown in Figure 1 , Figure 2 , Figure 4 , Figures 5-7 The difference between this embodiment and embodiment 1 is that the water spraying disc 1 comprises a shell 11, a middle partition plate 12 and an upper cover plate 13, the shell 11 is a rotary body, the shell 11 has an inner cavity, the opening of the inner cavity faces upward, the middle part of the shell 11 is formed with a first water guide column 111 extending upward, the first water passing channel 15 is located in the first water guide column 111, and the middle partition plate 12 has a connecting hole in the middle part.

[0032] The middle partition plate 12 is located in the inner cavity and is used for partitioning the inner cavity, the upper surface of the middle partition plate 12 is conical and the inclined surface is an arc surface, the upper surface of the middle partition plate 12 has a pit 121, which facilitates pressing and rotating the middle partition plate 12, specifically, the side wall of the inner cavity is formed with a limiting step, the lower surface of the middle partition plate 12 is in close contact with the limiting step, and the connecting hole of the middle partition plate 12 is threadedly connected with the circumferential surface of the first water guide column 111.
