For a better understanding of the objects, technical solutions and technical effects of the present invention, the present invention will be further explained below with reference to the drawings and examples. Meanwhile, it is stated that the embodiments described below are only for explaining the present invention and are not intended to limit the present invention.

As shown in fig. 1, the atomizing sterilizer comprises a spraying mechanism 1, a liquid supplementing box 2, a fan 3 and an atomizer 4, wherein the spraying mechanism 1 comprises a liquid storage part 13, an atomizing cavity 11 and an atomizing head 12 which are communicated, and the atomizer 4 is uniformly distributed at the bottom of the liquid storage part 13. The spray head 12 comprises at least one azimuth mist outlet 121, the opening of the azimuth mist outlet 121 is tilted up by a plurality of angles, preferably, the opening of the azimuth mist outlet 121 is tilted up by 45 degrees, in a specific embodiment, the spray head 12 is provided with four azimuth mist outlets 121 protruding a distance from the top side of the mist chamber 11, tilted up by 45 degrees again, and the orientation connecting lines of the four azimuth mist outlets 121 are crossed, when the sterilizer works, the sterilizer is used as the center, and disinfectant is sprayed to the periphery, so that the sterilization range is wider.

Besides the four-direction mist outlet 121, the top of the spray head 12 is also provided with a vertical mist outlet 122, which is positioned at the top of the atomization cavity 11, and the opening of the vertical mist outlet 122 is vertically upwards, so that the space range which cannot be sprayed by the four-direction mist outlet 121 can be made up, and the disinfection range can be further improved.

The liquid supplementing box 2 of the sterilizer is externally connected to one side of the atomizing cavity 11, the liquid supplementing box 2 is connected with the liquid storage part 13 of the atomizing cavity 11 through a liquid supplementing pipeline 21, when disinfectant is required to be added, disinfectant can be injected into the sterilizer only through the liquid supplementing box 2, the volume of the liquid supplementing box 2 is equal to three fourths of the volume of the liquid storage part 13, and the situation that the disinfectant exceeds the highest working liquid level of the liquid storage part 13 is avoided when the liquid supplementing box 2 is filled. In order to make the atomizer 4 obtain a better atomization effect, the disinfectant in the liquid storage portion 13 cannot be too full or too little, and at least the surface of the atomizer 4 is needed to be submerged, namely the lowest working liquid level of the liquid storage portion 13; the highest working liquid level of the liquid storage part 13 is not more than three fourths of the height of the liquid storage part 13, and the problem that the liquid replenishing amount is not well controlled in actual liquid replenishing operation is avoided, because the capacity of the liquid replenishing box 2 is designed, and the liquid replenishing box 2 is only required to be filled when the liquid storage part 13 is not provided with disinfectant.

The fan 3 is externally connected to the other side of the atomizing cavity 11, and is separately arranged on two sides of the atomizing cavity 11 with the fluid infusion box 2, so that the balance effect can be achieved.
