In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0027] Refer to Figures 1-6 Describe a humidifier capable of sterilizing air according to an embodiment of the present invention.

[0028] In one embodiment, as Figures 1-6 shown, a humidifier capable of sterilizing air includes a machine head 1 and a water tank 2 connected up and down. A fan 12 is provided in the machine head 1, and an air outlet 10 is provided at the upper part of the machine head 1. A filter assembly 3 is provided in the upper part of the inner cavity of the water tank 2, and uniformly distributed air inlet holes 21 are opened on the upper side wall of the water tank 2. A stirring assembly 22 is provided at the bottom of the water tank 2, and an installation box 23 is provided on one side of the inner cavity of the water tank 2. A sterilization module 24 and a water pump 25 are installed at the lower part of the inner cavity of the installation box 23. A plurality of water passing holes are opened on the lower side wall of the installation box 23. The water outlet of the water pump 25 is arranged below the filter assembly 3, and the sterilization module 24 has a plurality of electrolytic chambers.

[0029] Among them, the sterilization module 24 can electrolyze the water in the water tank 2 through multiple electrolysis chambers to continuously generate sterilization factors, achieving sterilization of water and air. The working principle of the sterilization module 24 is as follows:

[0030] The liquid to be electrolyzed is tap water. Since the waterworks uses chlorine-containing disinfectants to disinfect tap water, there are certain residual chloride ions in the tap water. Therefore, the following reactions also occur at the anode:

[0031] 2Cl- → Cl2 + 2e-

[0032] Cl2 + H2O → HClO + HCl

[0033] HCl → Cl2↑ + H2↑

[0034] HClO 〈==〉 ClO- + H+

[0035] The hypochlorous acid generated in the above reactions is the sterilization factor, which has the function of sterilization and disinfection.

[0036] At the same time, it is necessary to prevent side reactions from occurring to prevent the production of too much oxygen and the generation of ozone.

[0037] The side reactions are:

[0038] In an alkaline environment, 4OH- - 4e- → 2H2O + O2↑

[0039] In an acidic environment, 4H2O - 4e- → 4H+ + O2↑
