Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, specifically to an air purifier that deodorizes and sterilizes. Background Technology

[0002] With the development of society, people are paying more and more attention to the air quality of their living environment, and air purifiers have emerged as a result. Air purifiers are products that can adsorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to improve air cleanliness.

[0003] Air purifiers have filters to purify pollutants present in the air. Outside air drawn into the air purifier passes through the filters to remove pollutants, and the purified air is then discharged back to the outside.

[0004] The existing technology still has some problems: activated carbon adsorbs specific odorous gases quickly and has low efficiency, and cannot decompose these gases, resulting in a short filter life. In addition, the filter can only intercept particulate matter with attached microorganisms and cannot actively kill bacteria and viruses. In general, the deodorization and sterilization capabilities cannot meet the needs. Furthermore, the air outlet direction is fixed, and it is difficult to deliver the purified clean air to the required areas, such as pet beds and odor sources, in a targeted and rapid manner, resulting in low overall purification efficiency.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] First embodiment: Radial multi-layer purification cylinder See Figure 1 and Figure 5 This embodiment demonstrates an air purifier with a radial multi-layer structure that deodorizes and sterilizes, suitable for most living rooms and bedrooms. It comprehensively treats common odors, bacteria, and pet hair, etc., and includes an air purifier 1, which has a purification chamber 2 and an air intake chamber 3 arranged from bottom to top inside. A purification cylinder 4 is fixedly installed on the bottom wall of the purification chamber 2 by a snap-fit. Multiple air inlets 5 are opened on the outer periphery of the air purifier 1, and a grille 6 is detachably installed on the air inlet 5 to prevent large foreign objects from entering. Preferably, it is installed and removed by magnetic adsorption.

[0023] Then, a drive box 7 is fixedly connected to the upper end of the air purifier 1 by bolts. The drive box 7 has an air distribution chamber 8 and a drive chamber 9 machined from bottom to top. Four release heads 10 that can tilt and swing are evenly distributed on the outer periphery of the drive chamber 9. A centrifugal fan 11 is installed in the air intake chamber 3. The lower end and the upper end of the air intake chamber 3 have a first air duct 12 and a second air duct 13, respectively, which connect the purification chamber 2 and the air distribution chamber 8.

[0024] The core of this embodiment lies in the radial multi-layer structure of the purification cylinder 4. This structure, from the outside to the inside, consists of: Pre-filter layer 14: Made of PET material, its main function is to filter and intercept large particulate pollutants such as pet hair, dust, and particulate matter floating in the air.

[0025] Activated carbon layer 15: It is filled with coconut shell activated carbon particles with high iodine value (iodine value ≥1000mg / g). It has a huge specific surface area and can efficiently adsorb odor molecules such as ammonia, hydrogen sulfide, and formaldehyde, as well as volatile organic compounds in the air.

[0026] Antibacterial and disinfection layer 16: Using honeycomb aluminum as the substrate, nano-titanium dioxide photocatalyst is loaded on its surface. Under the irradiation of ultraviolet lamp 19, it can generate strong oxidizing hydroxyl radicals, which can completely decompose residual organic odor molecules and kill bacteria, viruses and other microorganisms that have passed through the first two layers.

[0027] Working principle: When the fan 11 is turned on, indoor air is drawn into the purification chamber 2 through the air inlet 5, and passes through the pre-filter layer 14, activated carbon layer 15 and antibacterial disinfection layer 16 of the purification cylinder 4 in sequence. Pollutants are removed step by step. The purified air is drawn by the fan 11 and enters the air distribution chamber 8 through the first air duct 12 and the second air duct 13 in sequence. Finally, it is discharged into the room through the release head 10. The first embodiment has comprehensive functions, compact structure and is suitable for comprehensive purification of daily home environment.

[0028] Second embodiment: Axially segmented purification cylinder See Figure 6 This embodiment provides another way to implement the purification cylinder, which is suitable for places with high odor concentration such as toilets, kitchens, hospital waiting rooms, and pet shops, and where the control of bacteria and viruses is strict and requires strong and thorough decomposition and disinfection. It shares the same main structure, drive box 7 and swing mechanism as Embodiment 1, but the difference lies in the structure of the purification cylinder 4.

[0029] In this embodiment, the purification cylinder 4 adopts an axially segmented structure, which is divided into two sections from bottom to top:

[0030] First functional section 17 (deodorization section): Its interior is filled with modified alumina balls with potassium permanganate loaded on the surface. Potassium permanganate is a strong oxidant that can efficiently catalyze the decomposition of malodorous gas molecules (such as H2S, NH3) in the air through redox reactions, converting them into harmless substances.

[0031] Second functional section 18 (sterilization section): It is filled with ultraviolet light-excited nano-Ag / TiO2 composite particles. The combination of nano-silver and titanium dioxide produces a synergistic effect, which can generate more free radicals under ultraviolet light irradiation, deeply killing bacteria and viruses that have penetrated into this section. The sterilization spectrum is broader and the effect is longer lasting.

[0032] General preferred embodiments and working principles See Figure 3 , Figure 4 as well as Figure 7 As shown, both of the above embodiments can integrate the following preferred solutions:

[0033] An ultraviolet lamp 19 is fixedly connected to the bottom wall of the purification chamber 2 at the center of the purification cylinder 4. This ultraviolet lamp 19 can simultaneously provide ultraviolet light source for the antibacterial disinfection layer 16 of the first embodiment and the sterilization section of the second embodiment, thereby stimulating a photocatalytic reaction.

[0034] The drive box 7 has four openings 20 on its outer periphery. Each opening 20 is rotatably connected to a special-shaped gear 21 via a bearing. Each special-shaped gear 21 has an empty tube 22 fixedly connected to its opposite sides. The release head 10 is fixedly connected to the end of the empty tube 22 away from the special-shaped gear 21. The bottom wall of the air distribution chamber 8 is fixedly connected to an air collection box 23. The air collection box 23 is connected to the second air duct 13. Each empty tube 22 is connected to the air collection box 23 via a flexible air tube 24.

[0035] A vertical lead screw 25 is rotatably connected to the upper and lower ends of the drive cavity 9 via bearing seats. A lifting plate 26 is threaded onto the lead screw 25. Four fixed guide rods 27 slide through the lifting plate 26. The two ends of the guide rods 27 are fixed to the inner wall of the drive cavity 9. Four racks 28 are fixedly connected to the outer periphery of the lifting plate 26. The irregular gears 21 mesh with the racks 28. A motor 29 is fixedly connected to the upper end of the drive box 7 via a bracket. The output shaft of the motor 29 is connected to the lead screw 25 via a coupling. The motor 29 has a self-locking function.

[0036] Oscillating working principle: According to the air supply needs, the user starts the motor 29, which drives the lead screw 25 to rotate. Under the constraint of the guide rod 27, the lifting plate 26 will rise or fall in the vertical direction. When the lifting plate 26 moves, it drives the rack 28 on it to move synchronously. The rack 28 drives the four irregular gears 21 meshing with it to rotate synchronously, thereby driving the air pipe 22 and the release head 10 to swing up and down, expanding the air supply range. The purified air in the air distribution chamber 8 first enters the air collection box 23 for temporary storage, and then is delivered to the air pipe 22 through the flexible air pipe 24. The air pipe 24 has a certain degree of extensibility and bendability, and is finally discharged into the room through the release head 10.

[0037] Meanwhile, users can adjust the angle of the release head 10 by controlling the forward and reverse rotation of the motor 29, thereby achieving directional air delivery, aiming at the source of odor on the ground and at the pet's bed, and directly delivering the purified clean air to areas with high pollution concentration, avoiding the spread of clean air in non-target areas, and improving local purification efficiency. Moreover, the four release heads 10 are evenly distributed around the drive box 7, and with the tilt angle adjustment, full-dimensional coverage can be achieved. For example, in a living room scenario, the release heads 10 swing towards the four walls to prevent clean air from accumulating in the central area and improve purification efficiency.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
