The other is to spray disinfectant on the hands to achieve the purpose of cleaning hands by directly killing bacteria; it still takes a long time to rub hands, although it takes less time than washing hands, it does more damage to the skin. Therefore, a disinfection device that is fast and less harmful to the skin is needed.

In the prior art, the Chinese patent CN03218206.6 discloses a hand sanitizer, which is characterized in that, "a housing, an ultrasonic atomizer and a fan are arranged in the composition, wherein an ultrasonic atomization chamber is arranged in the housing, The ultrasonic nebulizer is located in the disinfectant in the ultrasonic atomization chamber, the exhaust port of the fan leads to the disinfection port of the housing through the pipeline, and the fan is fixed in the housing.” But the disadvantage of this patent is: the disinfectant after atomization The small droplet size (generally a few microns to tens of microns) is very easy to diffuse with the airflow. As a result of the open structure, only a small part of the disinfectant droplets are adsorbed on the hands, and the rest are all diffused into the air. The low proportion of drops on hands (that is, the poor efficiency of the atomizer) will also cause a great waste of disinfectant; what is more serious is that the characteristics of disinfectant droplets are easy to diffuse with the air, so that they can irritate the respiratory tract and cause the user's body to be damaged. discomfort.

Both the ultrasonic atomizer and the liquid storage tank are fixed at the bottom of the box. The pipeline includes a section of straight pipe and a section of 180-degree elbow, which are respectively fixed on the side and top of the box. Among them, the straight pipe is located directly above the ultrasonic atomizer, and there is a certain vertical distance between the liquid storage tank; one end of the 180-degree elbow is connected with the straight pipe, and the edge of the other end is connected with the first deflector, and the first deflector The flow plate is slightly inclined downward toward the straight pipe, and its edge is glued to the box or pipe. A fan (motor and fan blade) is installed inside the straight pipe, and the fan shaft is fixed at the center of the cross section of the straight pipe with a rigid bracket. On one side of the box wall whose vertical height is slightly lower than the first deflector, there is an opening for reaching out. A second deflector is provided at a place slightly lower than the opening, which is slightly inclined downward toward the liquid storage tank, and its edge is glued to the edge of the box body or the liquid storage tank. The ultrasonic atomizer is connected in parallel with the fan, and then connected in series with the foot switch, so that the foot switch controls the start and stop of both at the same time.

The utility model adopts a circulation spraying structure of disinfectant liquid droplets, which can effectively reduce the waste of disinfectant liquid and stimulate the respiratory tract and increase the proportion of disinfectant liquid droplets on hands. The foot switch is used to simultaneously control the start and stop of the ultrasonic atomizer and the fan. It has the advantages of simple structure, low cost and high reliability.
