Technical Field

[0001] This utility model belongs to the field of atomization disinfection technology for central air conditioning, and particularly relates to an atomization disinfection device for central air conditioning. Background Technology

[0002] Existing central air conditioning systems generally lack efficient, low-resistance, and sustainable disinfection methods. Methods such as ultraviolet light, ozone, or chemical fumigation have drawbacks including large blind spots, high energy consumption, corrosion of pipes, and potential harm to human health. Directly spraying disinfectants in liquid form can cause water accumulation in ducts, increased fan load, and secondary moisture contamination. To improve disinfection efficiency, a misting disinfection device for central air conditioning systems is proposed, which effectively atomizes disinfectant and improves disinfection efficiency. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a disinfection device for central air conditioning that achieves good atomization efficiency by using secondary atomization treatment, where the disinfectant diffuses along the direction of the air conditioning airflow, and the airflow direction is consistent with the tilt direction of the microporous ceramic atomizing plate, which effectively improves the atomization diffusion effect and increases the diffusion efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an atomizing disinfection device for central air conditioning, comprising an air duct, an air duct flange at the bottom of the air duct, a solution tank below the air duct, and a solution tank flange adapted to the air duct flange at the top of the solution tank;

[0005] The air duct is equipped with two inclined microporous ceramic atomizing plates. The surface of the microporous ceramic atomizing plates is provided with an annular piezoelectric actuator. A cavity is formed between the microporous ceramic atomizing plates. An atomizing nozzle is provided inside the cavity. The atomizing nozzle extends into the solution tank through a flexible tube.

[0006] Preferably, the solution tank is equipped with a liquid level sensor and a replenishment pump, and the replenishment pump is connected to an external container through a pipeline.

[0007] Preferably, the air duct flange and solution tank flange are replaced with threaded pipe connections for fixation.

[0008] Preferably, the included angle α between the microporous ceramic atomizing plate and the air duct is between 25° and 42°.

[0009] Preferably, the wind direction is consistent with the tilt direction of the microporous ceramic atomizing plate, that is, the microporous ceramic atomizing plate is the windward side.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Through secondary atomization treatment, the disinfectant diffuses along the direction of the air conditioning airflow, achieving a good atomization efficiency. The angle α between the microporous ceramic atomizing plate and the air duct is between 25-42°, and the airflow direction is consistent with the tilt direction of the microporous ceramic atomizing plate, which effectively improves the atomization diffusion effect and increases the diffusion efficiency.

[0012] 2. In terms of intelligence, timely replenishment can be achieved through liquid level sensors and replenishment pumps, effectively realizing automatic replenishment. Timers can also be added to realize functions such as timed atomization disinfection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0018] See appendix Figure 1-2 As shown, a misting disinfection device for central air conditioning includes an air duct 2, an air duct flange 21 at the bottom of the air duct 2, a solution tank 1 below the air duct 2, and a solution tank flange 12 at the top of the solution tank 1 that is compatible with the air duct flange 21.

[0019] The air duct 2 is provided with two inclined microporous ceramic atomizing plates 13. The surface of the microporous ceramic atomizing plate 13 is provided with an annular piezoelectric actuator 16. A cavity 14 is formed between the microporous ceramic atomizing plates 13. An atomizing nozzle 15 is provided inside the cavity 14. The atomizing nozzle 15 extends into the solution tank 1 through a hose 11.

[0020] Preferably, the solution tank 1 is equipped with a liquid level sensor and a replenishment pump, and the replenishment pump is connected to an external container through a pipeline.

[0021] Preferably, the air duct flange 21 and the solution tank flange 12 are replaced with threaded pipe connections for fixation.

[0022] Preferably, the included angle α between the microporous ceramic atomizing plate 13 and the air duct is between 25° and 42°.

[0023] Preferably, the wind direction is consistent with the tilt direction of the microporous ceramic atomizing plate 13, that is, the microporous ceramic atomizing plate 13 is the windward side.

[0024] Working principle: Disinfectant is placed in solution tank 1 and atomized through atomizing nozzle 15 for the first time. However, due to the poor atomization effect of industrial atomizing nozzle and the large atomized particle size, the disinfectant spray is driven by ring piezoelectric actuator 16 and atomized through the microporous ceramic atomizing plates 13 with smaller pores for the second atomization treatment. It diffuses with the direction of air conditioning airflow, achieving a good atomization efficiency treatment effect.

[0025] In terms of equipment setup, the air duct flange 21 and solution tank flange 12 can be replaced with threaded pipe connections for fixation, effectively reducing the ease of equipment installation and addressing both long-term and short-term treatment scenarios. The included angle α between the microporous ceramic atomizing plate 13 and the air duct is between 25-42°, and the airflow direction is consistent with the tilt direction of the microporous ceramic atomizing plate 13, effectively improving the atomization diffusion effect and increasing the diffusion efficiency.

[0026] In terms of intelligence, timely replenishment can be achieved through liquid level sensors and replenishment pumps, effectively realizing automatic replenishment. Timers can also be added to realize functions such as timed atomization disinfection.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
