Description

Disinfection apparatus for gate enable to spray disinfectant uniformly that sprays disinfectant uniformly through a plurality of nozzles

It relates to an entrance gate type sterilization and disinfection device that sterilizes a user by spraying a disinfectant solution.

Due to a highly contagious virus such as Corona virus (COVID-19), strengthening the quarantine system is emerging as a social problem that is most urgently needed. Corona 19 is a respiratory infectious disease, and the pathogen is SARS-CoV-2, and it is mainly spread by droplets of an infected person penetrating into the respiratory tract or the mucous membranes of the eyes, nose, and mouth. That is, it is spread by coughing or sneezing, or by touching a material contaminated with the virus and then touching your eyes, nose, and mouth.

Therefore, in order to prevent infection of COVID-19, precautions must be observed. Individuals must wash their hands thoroughly under running water for at least 30 seconds, and those with respiratory symptoms such as coughing must wear a mask. There are precautions such as wearing a mask when visiting and using a mask, observing cough etiquette, and not touching your eyes, nose, and mouth. In addition, multi-use facilities including schools, service areas, churches, stores and government offices must be ventilated at least twice a day and disinfected by periodically spraying disinfectant, but a separate quarantine manager or quarantine manager must be designated. , in the case of multi-use facilities, it is a space where visitors, including users who regularly commute to work and visitors from outside, come and go, and are exposed to infectious diseases due to frequent access and various visitors from outside. There was a problem.

The air pipe is an air inlet pipe, which is a path through which the air pressurized by the compressor flows into the first and second solenoid valves, and a path through which the air discharged from the first and second solenoid valves is supplied to the plurality of injection nozzles. Including an air discharge pipe,
The diameter of the air discharge pipe is formed to be smaller than the diameter of the air inlet pipe, so that the pressure of the air passing through the air discharge pipe is greater than the pressure of the air passing through the air inlet pipe. The method of claim 1,
a second disinfectant solution level sensor installed in the upper disinfectant solution reservoir to detect the level of the disinfectant solution stored in the upper disinfectant solution reservoir;
When the level of the disinfectant solution in the upper disinfectant solution reservoir sensed by the second disinfectant solution level sensor is less than the lower limit level, the control unit controls the pump so that the disinfectant solution in the lower disinfectant solution reservoir moves to the upper disinfectant solution reservoir. Entrance gate type disinfection device. 8. The method of claim 7,
It further comprises a disinfectant counterflow pipe having one end connected to the lower disinfectant solution reservoir and the other end connected to the upper disinfectant solution reservoir through which the disinfectant solution moves from the lower disinfectant solution reservoir to the upper disinfectant solution reservoir by the pump.
The control unit controls the pump to move the disinfectant solution until the level of the disinfectant solution in the upper disinfectant solution reservoir reaches the upper limit level;
The upper limit water level is located below the distal end of the disinfectant backflow pipe connected to the upper disinfectant reservoir.
