Description

Technical Field

[0001] The present invention relates to the technical field of ozone disinfection, in particular to a wall-mounted ozone disinfector. Background Art

[0002] Ozone, also known as triatomic oxygen, is a strong oxidant used in air disinfection to oxidize and decompose the enzymes required by bacteria in the air to produce glucose, thereby inactivating and killing the bacteria. Ozone can be produced using the dielectric barrier discharge (DBD) method. An alternating high-voltage electric field generates a corona in the gas. The free, high-energy electrons in the corona dissociate oxygen molecules, which then aggregate into ozone molecules through collisions. The DBD method offers relatively low energy consumption and high ozone production per unit. The gas source can be dry air, oxygen, or an oxygen-enriched gas with a high oxygen concentration. Therefore, this method is widely used in industrial ozone synthesis.

[0003] Existing indoor ozone disinfection devices lack a cooling device in the DBD module, which causes the DBD reactor to always maintain a high temperature during operation. This can easily cause the electrode plates to break down over time, greatly reducing its service life. Most of the internal components of the device are fixed using welding and other methods, making subsequent maintenance and replacement difficult. Ozone is generated on one side of the device and has a low degree of mixing with the air, so it cannot be discharged evenly during emission.

[0004] Therefore, improvements are made to the above problems. Summary of the Invention

[0005] Therefore, the present invention is designed in response to the above problems. Through the design of the clip and exhaust duct, the present invention solves the problems of existing DBD reactors, such as high temperatures resulting in a short lifespan, complex component installation, replacement, and maintenance, low mixing with air, and uneven ozone discharge.

[0011] Beneficial effects of the present invention

[0012] The arrangement of the rotary fan on the right side of the DBD reactor of the present invention can, when the rotary fan rotates, cool the DBD reactor on the one hand, and guide the ozone generated by the operation of the DBD reactor into the guide cover on the other hand. During the guidance process, the ozone and air are mixed to a certain extent. At the same time, the rotary fan is slightly larger than the DBD reactor and the DBD reactor is arranged vertically. This allows the airflow generated by the rotary fan to carry away as much ozone as possible without affecting the air flow rate inside the DBD reactor, thereby avoiding the problem of ozone accumulation near the DBD reactor.

[0013] The arrangement of the snap-fit ​​fixing device and the fan fixing device of the present invention enables the operator to remove the crossflow fan for maintenance and replacement by removing screws 1 and 2 during the specific implementation process;

Finally, under the airflow generated by the cross-flow fan, the air and ozone are fully mixed with the air and discharged into the air outside the device through the air outlet baffle for sterilization and disinfection, thus avoiding the problem of uneven discharge of ozone.

[0039] Working principle of the present invention:

[0040] First, under the control of the power controller 9, the motor 6 starts to rotate, and the rotation of the motor 6 drives the solid cylinder 141 at the right end of the cross-flow fan 14 connected thereto. The solid cylinder 141 then transmits the rotation state to the rotating ring 142 connected thereto, thereby driving the fan blades and the fixed shaft 85 connected thereto; finally, the fan blades and the hollow exhaust pipe 84 rotate synchronously, driving the conical drainage block 83 on the left side of the cross-flow fan 14, and the rotation of the conical drainage block 83 drives the rotating fan 82 connected thereto to rotate, and the rotating fan 82 rotates to generate an airflow to move the DBD reactor 10 The ozone generated during operation is guided into the guide cover 81, and then enters the hollow exhaust pipe 84 under the guidance of the conical guide block 83, and is then released into the cross-flow fan 14 through the exhaust holes on its surface. Since the ozone is released in the gap between the fan blades and the hollow exhaust pipe 84, the cross-flow fan 14 generates laminar flow after acting on the gas, so that the ozone is mixed flatly inside each layer of the expelled air flow, making the ozone mixing more uniform. The gas is finally fully stirred and mixed with the air under the airflow generated by the cross-flow fan 14, and then discharged into the air outside the device through the air outlet baffle 4 for sterilization and disinfection.
