In this embodiment, the atomizing assembly 1 includes a water storage tank 11 and an ultrasonic atomizing sheet. Wherein the open side of the water storage tank 11 is connected to the plasma generation assembly 2. The ultrasonic atomization sheet is arranged in the water storage tank 11 and can atomize the liquid in the water storage tank 11. The ultrasonic atomization sheet is used for atomizing water, so that the energy is saved, the environment is protected, and the atomization efficiency is high. In order to facilitate the filling of the water storage tank 11, the water storage tank 11 may optionally be detachably connected to the plasma generating assembly 2, and a user may be able to detach the water storage tank 11 and fill the water storage tank 11 with water. Preferably, in this embodiment, a water filling structure 111 is formed on a sidewall of the water storage tank 11. The water injection structure 111 is preferably, but not limited to, a water injection pipe. The storage tank 11 may be selected to be cylindrical or truncated cone shaped. Preferably, in this embodiment, the water storage tank 11 is in a truncated cone shape, and the area of the bottom is larger than that of the top, so that the stability of the disinfectant generating device can be improved.

In this embodiment, the disinfecting liquid generating device preferably further comprises a control module. A timer is provided in the control module, which is adapted to detect the water outlet time of the release structure 4. For example, the control module may be configured to start timing when a first instruction is received. The first command is preferably, but not limited to, a command to turn on the plasma generation assembly 2 and/or the gas-liquid distribution mechanism 3. The control module is in communication connection with the power supply device and the atomization assembly 1, and can control the power supply voltage of the power supply device to increase and the atomization amount of the atomization assembly 1 to increase when the water outlet time of the release structure 4 exceeds a preset value. The preset value can be set according to the requirements of the user. The disinfection liquid generator can adjust the concentration and the mist output of the disinfection liquid released by the disinfection liquid generator according to the concentration requirement of the environment on the disinfection liquid. When the space to be disinfected is small or the concentration of pollutants in the space is low, the concentration and the release amount of the disinfectant can be low, and the energy is saved; when the space needing to be disinfected is large or the concentration of pollutants in the space is high, the control module can increase the discharge power of the plasma generation assembly 2, so that the concentration of the disinfectant is increased, and the environment is disinfected quickly and thoroughly. The control module may include a programmable logic control unit (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control unit, etc., which are well known to those skilled in the art and will not be described in detail herein.
