Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and specifically to a disinfection and purification device for central air conditioners. Background Art

[0002] With the improvement of people's living standards and the increasing attention to health, the indoor air quality has been paid more and more attention. As an air conditioning device widely used in modern buildings, the central air conditioner plays an important role in adjusting the indoor temperature and humidity. However, during its operation, many problems related to air quality have also emerged.

[0003] On the one hand, the internal environment of the traditional central air conditioning system is relatively closed and humid. After long-term use of the ventilation ducts, a large amount of dust and dirt will accumulate, which become a breeding ground for microorganisms. Microorganisms such as bacteria, viruses, and molds multiply in large numbers in the ducts and are spread to every corner of the room along with the air flow of the air conditioner. On the other hand, although some central air conditioners are equipped with simple filtering devices, they usually can only filter larger dust particles, and have poor removal effects on fine particles, harmful gases, and microorganisms. The common filter screens are easy to clog, resulting in a decrease in ventilation efficiency, frequent replacement is required, increasing the use cost and maintenance workload. In terms of removing harmful gases such as formaldehyde and benzene, these harmful gases remain in the room for a long time, which will cause chronic harm to the human body and affect the health of the occupants. In addition, in places where people are active frequently, the risk of airborne diseases is high, which poses extremely high requirements for the disinfection and purification functions of the central air conditioner. Various odors and pollutants increase, and efficient purification equipment is needed to ensure a comfortable shopping environment.

One side of the bottom of the air freshener box 504 is rotatably installed with a second rotating rod 506. One side of the second rotating rod 506 is fixedly connected to a bottom plate 507. When it is necessary to replace the air freshener in the air freshener box 504, rotate the second rotating rod 506 to open the bottom plate 507, and the used air freshener drops into the collection component. The dosing component is installed above the air freshener box 504, facilitating the air freshener to fall from the discharge pipe 502 into the air freshener box 504.

[0050] The collection component includes a collection box 508 installed at the inner bottom end of the box body 1. The collection box 508 is installed at the bottom of the freshener box 504. At the outer bottom of the box body 1, a third rotating rod 509 is rotatably installed. On one side of the third rotating rod 509, a third blocking door 510 is fixedly installed. On the outer side of the third blocking door 510, a third handle 511 is installed. The third blocking door 510 is installed beside the collection box 508.

[0051] Specifically, the collection component includes a collection box 508 installed at the inner bottom end of the box body 1. The collection box 508 is used to collect impurities such as used freshener that fall from the freshener box 504. The collection box 508 is installed at the bottom of the freshener box 504, facilitating the collection of the used freshener. At the outer bottom of the box body 1, a third rotating rod 509 is rotatably installed. On one side of the third rotating rod 509, a third blocking door 510 is fixedly installed. On the outer side of the third blocking door 510, a third handle 511 is installed. The third blocking door 510 is installed beside the collection box 508. When the freshener in the collection box 508 accumulates to a certain extent, rotate the third rotating rod 509 at the outer bottom of the box body 1 to open the third blocking door 510, and take out the collection box 508 through the third handle 511 for replacement to ensure the continuous and effective air freshening function.

[0052] Working principle: During operation, external air enters from the air inlet 201 at one end of the box body 1. First, the air is processed by the filtering mechanism 2. The filter screen 202 at the front end inside the air inlet 201 will initially intercept larger dust particles, hair and other impurities in the air, playing a role of coarse filtration. Then, the air reaches the dispersion plate 203, and the air is evenly dispersed through multiple dispersion holes 204 inside the dispersion plate 203, enabling the air to come into contact with subsequent components more fully.

[0053] Subsequently, the air contacts the adsorption component. An adsorbent 207 is fixed on a rotating column 206 installed in the square frame 205 at the rear end inside the air inlet 201. The user can drive the rotation of the rotating column 206 by rotating the knob 208, thereby adjusting the position of the adsorbent 207 to enable the adsorbent 207 to more effectively adsorb harmful gases, odor molecules, etc. in the air, further purifying the air. When the adsorbent 207 is saturated with adsorption and needs to be replaced, the square frame 205 can be conveniently taken out for replacement by pulling the first handle 211 on the first blocking door 210 to make the square frame 205 slide along the first sliding groove 209.

[0054] The air that has undergone filtration and adsorption treatment enters the interior of the box body 1. Multiple ultraviolet lamps 302 connected between two connecting blocks 301 emit ultraviolet rays to disinfect the air. Ultraviolet rays can damage the DNA or RNA structure of microorganisms such as bacteria and viruses, rendering them inactive, thereby achieving the purpose of disinfection. When the ultraviolet lamps 302 need to be replaced, the first rotating rod 306 on one side of the exterior of the box body 1 is rotated to open the closing door 307. As a result, the sliders 303 at both ends of the connecting block 301 slide within the second sliding groove 305 on the fixed block 304, facilitating the removal of the ultraviolet component for replacement.

[0055] To enable the ultraviolet rays to irradiate the air more evenly, the motor 405 on the support frame 401 is started. The output end drives the rotating shaft 402 to rotate, and then the reflector 403 installed on the rotating shaft 402 rotates. By adjusting the angle of the reflector 403, the ultraviolet rays can be reflected to all corners inside the box body 1, ensuring that the air can fully receive ultraviolet irradiation and improving the uniformity of the disinfection effect.

[0056] The disinfected air continues to flow towards the other end inside the box body 1 and enters the air freshening mechanism 5. The storage tank 501 in the feeding component stores the air freshener. Meanwhile, the valve 503 on the discharge pipe 502 is opened, and the air freshener drips into the freshener box 504 below through the discharge pipe 502. The air freshener can slowly volatilize into the air through multiple circulation holes 505 on the outer surface of the freshener box 504, further purifying and scenting the air. When the air freshener in the freshener box 504 needs to be replaced, the second rotating rod 506 can be rotated to open the bottom plate 507, causing the used air freshener to fall into the collection component. The collection box 508 installed at the bottom end inside the box body 1 is used to collect these substances. Subsequently, the third rotating rod 509 at the bottom of the exterior of the box body 1 is rotated to open the third blocking door 510, and finally, the collection box 508 is taken out through the third handle 511 to achieve the purpose of replacing the air freshener.

[0057] Finally, the clean and fresh air that has undergone a series of treatments such as filtration, disinfection, and air freshening exits from the air outlet 6 at the other end of the exterior of the box body 1 and enters the indoor space, providing a healthy and comfortable air environment for people. Through the coordinated operation of each component, the entire central air-conditioning disinfection and purification device achieves efficient purification and freshening treatment of the air, meets people's requirements for indoor air quality, and effectively improves the comfort and health level of the indoor environment.

[0058] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
