[0002] An air purifier, also known as an air cleaner, air refresher, or purifier, is a product that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), effectively improving the cleanliness of the air.

[0003] Traditional air purifiers use fans to allow air to enter the air purifier, and the air passes through the filter materials inside, such as non-woven fabrics, filter paper, fibers, etc., to separate pollutants from the air and achieve the purpose of purification. However, this type of air purifier uses physical filtration and adsorption to remove dust. Although it is effective to a certain extent, it only plays a role in removing pollutants and cannot fundamentally eliminate the pollution caused by viruses, microorganisms, etc. Therefore, some manufacturers have added disinfection lamps in the air purifiers to kill viruses or microorganisms by irradiation with disinfection lamps. The disinfection lamp is usually fixedly screwed and installed on the top or bottom of the air purifier to disinfect the air from top to bottom or from bottom to top, and the installation structure is simple. However, since the ultraviolet lamp has a certain service life, it is necessary to replace the ultraviolet lamp regularly. However, in the existing structure, the disassembly and assembly of the lamp is very troublesome, and ordinary consumers cannot replace it by themselves, so it is necessary to make further improvements to it.

[0022] The present invention is further described in detail below with reference to the accompanying drawings. A vertical air purifier that is convenient for replacing ultraviolet lamps, characterized in that: it includes a cabinet 1, a front opening and side openings are provided in the front and on both sides of the cabinet 1, a front door panel 2 and two side door panels 3 are detachably mounted on the front opening and the side openings, the cabinet 1, the front door panel 2 and the two side door panels 3 are mutually surrounded to form an air cavity; a purification device is installed in the air cavity, air enters the air cavity through the air inlet 6 below the front door panel 2 and the side door panels 3, and is discharged from the air outlet 7 on the top of the cabinet 1 after being filtered and disinfected by the purification device;

[0023] The purification device includes a serpentine air duct 5 formed by a plurality of longitudinally distributed wind partitions 4, one side of the wind partition 4 is provided with an air outlet slot 41, and the air outlet slots 41 between the upper and lower wind partitions 4 are staggered; the purification device also includes a filter screen 8 arranged in the serpentine air duct 5, the surface of the filter screen 8 or the surface of the wind partition 4 is sprayed with a photocatalyst layer, and ultraviolet lamps 9 are arranged on both sides of the serpentine air duct 5 to irradiate the photocatalyst layer.

[0024] The surface of the ultraviolet lamp tube 9 is sleeved with a mounting ring 10 , and a mounting groove 42 is provided on the side of the wind shield plate 4 , and the ultraviolet lamp tube 9 is fixed in the mounting groove 42 by snapping the mounting ring 10 .

[0025] The outer cylindrical surface of the mounting ring 10 is inwardly recessed to form a clamping groove 101, and the clamping groove 101 clamps the mounting groove 42 of the wind shielding plate 4 therein.

[0026] The mounting groove 42 is a U-shaped opening groove.

[0027] A fan 11 is also installed on the upper part of the air cavity, and the air outlet of the fan 11 is connected to the air outlet 7 on the top of the air purifier.

[0028] The air inlet 6 is also covered with a shading cover 12 . The side of the shading cover 12 facing the air inlet 6 is recessed inward to form a groove 121 . Air enters the groove 121 from the air inlet 6 and enters the air cavity through an opening provided at the bottom of the groove 121 .

[0029] Working principle: In this case, the cabinet of the air purifier has a front opening and side openings in front and on both sides. The front door panel and the door panels on both sides are detachably installed on the front opening and the side openings. The cabinet, the front door panel and the door panels on both sides are mutually surrounded to form an air cavity. When the ultraviolet lamp needs to be disassembled, only the door panels on both sides need to be disassembled, and the ultraviolet lamp becomes directly exposed to the user's line of sight. At this time, the user pulls the mounting ring of the outer sleeve of the ultraviolet lamp out of the mounting groove of the wind shield plate, and the ultraviolet lamp can be easily replaced and maintained. The structure is simple, the disassembly operation is convenient and quick, and the professional technical requirements are low, which is convenient for users to operate by themselves.

[0030] Furthermore, the purification device includes a serpentine air duct formed by splicing a number of longitudinally distributed air baffles, wherein an air outlet slot is provided on one side of the air baffle, and the air outlet slots between the upper and lower air baffles are staggered. When the air enters the air cavity through the air inlet below the front door panel and the side door panel, it flows upward into the serpentine air duct under the action of the fan, and the air moves in a serpentine manner. Each time it flows through the gap between adjacent air baffles, it can be filtered once through the filter net. The air undergoes multiple filtrations from the air inlet to the air outlet, which enhances the air filtration effect and improves the air quality.

[0031] Among them, an installation groove is set on the side of the wind partition, and the ultraviolet lamp tube is fixed in the installation groove by a mounting ring buckle. The ultraviolet lamp tube is set across both sides of the serpentine air duct. Therefore, each time the air flows through the gap between adjacent wind partitions, it is irradiated and disinfected on one side by the ultraviolet lamp tube. The air undergoes multiple irradiation disinfections in the process from the air inlet to the air outlet, which effectively enhances the effect of air sterilization and disinfection, completely kills pollutants such as viruses or microorganisms, and ensures the quality of the air.

[0032] Among them, the surface of the filter or the surface of the wind shield is sprayed with a photocatalyst layer. Under the irradiation of the ultraviolet lamp, the photocatalyst layer produces substances that can be used to decompose viruses or microorganisms, effectively degrading toxic and harmful gases in the air, and further enhancing the disinfection and sterilization ability of the air purifier.

[0033] Furthermore, the air inlet is covered with a shading cover, and the side of the shading cover facing the air outlet is inwardly recessed to form a groove, and air enters the groove from the air inlet and enters the air cavity through the opening provided at the bottom of the groove. The shading cover not only ensures the inflow of air, but also effectively blocks the irradiation of the ultraviolet lamp into the room, effectively protecting the user's safety, preventing the user or pets from being exposed to ultraviolet rays, and improving its safety, so it can be widely promoted for use.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
