[0002] Disinfection and sterilization of public environments is particularly important. Although the existing fresh air system can replace the indoor air while removing and disinfecting the air containing pathogens, for environments with large traffic and many objects in the room, such as classrooms, it is easy for bacteria and viruses to accumulate due to students' communication and contact. Although some bacteria and viruses in the air can be eliminated through ventilation, the bacteria and viruses remaining on tables and chairs cannot be eliminated. Therefore, a fresh air disinfection system for campus classrooms is needed.

[0003] In order to achieve the effect of sterilizing and disinfecting the classroom while replacing the air, a disinfectant spraying device will be installed in the fresh air system.

[0029] By slidingly connecting an adjustment mechanism composed of a piston 23, a sleeve 25, a first elastic member 24, a circular plate 26, a first bearing 27 and a screw 7 in the storage bottle 22, the height of the piston 23 in the storage bottle 22 can be manually adjusted using the adjustment mechanism, thereby adjusting the amount of disinfectant water carried out in the air. At the same time, the resilience of the first elastic member 24 can be used to ensure that the height of the disinfectant water in the storage bottle 22 remains constant, thereby ensuring that the disinfectant water carried by the rotating plate 20 will not be reduced in subsequent carrying content due to gradual use.

[0030] A bracket 17 is fixed in the ventilation pipe 2, and a circular hole is provided on the side of the bracket 17 facing the fan 4, a second bearing 18 is connected and fixed in the circular hole, a rotating rod 19 is connected and fixed in the second bearing 18, a plurality of rotating plates 20 arranged in an annular manner and equidistantly are connected and fixed to the annular surface of the rotating rod 19, and the rotating plate 20 is located in the storage cup, a plurality of arc plates 21 arranged in an annular manner and equidistantly are connected and fixed to the annular surface of the end of the rotating rod 19 away from the bracket 17, and a plurality of hinged plates 5 arranged in an annular manner and equidistantly are hinged to the annular inner surface of the ventilation pipe 2, the hinged plate 5 is hinged to the side of the arc plate 21 facing the fan 4, and a second elastic member 6 is connected and fixed to the opposite sides of the plurality of hinged plates 5, the second elastic member 6 is a spring, the second elastic member 6 is in a normal state, and the end of the second elastic member 6 away from the hinged plate 5 is connected and fixed in the ventilation pipe 2.

[0031] By installing a hinge mechanism consisting of a hinge plate 5 and a second elastic member 6 on the side of the arc plate 21 facing the fan 4, the hinge mechanism is used to control the size of the ventilation pipe 2, thereby controlling the flow rate of air passing through the arc plate 21, ensuring that the fan 4 can make the rotating plate 20 rotate at the same speed under different powers, so that the amount of disinfectant water carried out of the storage bottle 22 by the air is consistent.

[0032] A plurality of support rods 11 are connected and fixed to the annular inner surface of one end of the ventilation duct 2 away from the fan 4, and a plurality of equidistantly arranged swing plates 12 are hingedly connected to the side of the support rod 11 facing the outside of the ventilation duct 2, and the swing plates 12 are hingedly connected to each other by connecting rods 13, and a third elastic member 28 is connected and fixed to the upper surface of the uppermost swing plate 12, and the third elastic member 28 is a spring. The third elastic member 28 is in a normal state, and the end of the third elastic member 28 away from the swing plate 12 is connected and fixed to the upper side of the annular inner surface of the ventilation duct 2.

[0033] By installing a swing mechanism consisting of a support rod 11, a swing plate 12 and a third elastic member 28 at the end of the ventilation duct 2 away from the fan 4, the swing mechanism is used to adjust the angle at which air is discharged from the ventilation duct 2, ensuring that disinfectant can be carried to all parts of the classroom both in the case of fast and slow air flow rates.

[0034] A fixing buckle 14 is connected to the upper surface of the uppermost swing plate 12, and a slot 15 matching the buckle 14 is provided at one end of the ventilation duct 2 in the classroom. The upper side of the annular surface of one end of the ventilation duct 2 in the box body 1 is connected to a communicating circular tube 8, and the end of the circular tube 8 away from the ventilation duct 2 passes through the box body 1. Both sides of the annular surface of the end of the circular tube 8 away from the ventilation duct 2 are connected to fixed plates 9, and interception plates 10 are hinged on the upper surface of the fixed plates 9, and the ends of the two interception plates 10 away from the fixed plates 9 are in contact.

[0035] The specific operation process of the present invention is as follows: start the fan 4 to discharge the air outside the classroom into the classroom through the ventilation pipe 2, and in the process of discharging into the classroom, drive the arc plate 21 to rotate, the arc plate 21 rotates to drive the rotating rod 19 and the rotating plate 20 to rotate, the rotating plate 20 rotates to pick up the disinfectant in the storage bottle 22, and then floats into the classroom with the air.

[0036] When the working power of the fan 4 is adjusted according to the ventilation requirements of different seasons and the number of people in the classroom, the air flow rate discharged into the classroom by the fan 4 is different. When the air flow rate is fast, the air has a large extrusion force on the hinged plate 5, and the pressure of the hinged plate 5 squeezing the second elastic member 6 is large, thereby increasing the cross-section of the ventilation pipe 2 at this time. When the air flow rate is slow, the hinged plate 5 is squeezed by the second elastic member 6 to reduce the cross-section of the ventilation pipe 2, thereby increasing the air flow rate when the air passes through the hinged plate 5, thereby increasing the rotation speed of the arc plate 21, thereby driving the rotation speed of the rotating plate 20 to increase, and avoiding a decrease in the content of disinfectant water brought into the classroom by the air.

[0037] During class, in order to prevent the smell of disinfectant from affecting students' normal classes, the height of the piston 23 in the storage bottle 22 can be adjusted by using the screw 7, so that the rotating plate 20 cannot contact the disinfectant in the storage bottle 22. At the same time, the buckle 14 and the slot 15 can be used to block one end of the ventilation pipe 2 in the classroom, so that air can enter the classroom through the circular tube 8, avoiding the air from blowing directly to the students in a cold environment and causing them to get cold, and avoiding direct blowing and causing chalk dust to scatter.

[0038] When the classroom needs to be disinfected after class, the buckle 14 is removed from the slot 15 to allow air to enter the classroom through the ventilation pipe 2, and the disinfectant is sprayed to various parts of the classroom by using the air flow. When spraying, the air flow rate is small. In order to prevent the disinfectant from being sprayed to areas far away from the fresh air system, the third elastic member 28 is used to drive the swing plate 12 to rotate upward, so that an upward arc appears when the air flows, so that the disinfectant can drift to a farther place in the classroom. When the air flow rate is large, the two interception plates 10 in the circular tube 8 are opened at the same time, so that part of the air is discharged through the circular tube 8, so as to prevent the air flow rate from being too large and causing the area close to the fresh air system to be unable to spray the disinfectant.

[0039] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
