Problems solved by technology

[0002] At present, most of the air purifiers with bactericidal and formaldehyde-removing effects on the market need to use filters, or negative ions, ozone and other methods to remove bacteria, viruses, formaldehyde, etc. With the extension of use time, the effect will gradually decrease. If the filter is not replaced in time , there will be secondary pollution
At the same time, the product cost is high, the structure is complex, and the service life is short

Embodiment 1

[0034] Such as figure 1 As shown, an air purifier with sterilizing and formaldehyde-removing effect provided in this embodiment includes a purifier housing 1, a top cover 2 is arranged on the top of the purifier housing 1, and a top cover 2 is placed on the purifier housing 1 below the top cover 2. The air inlet 3 is set, and the interior of the purifier housing 1 is divided into a purification chamber 4 and an air outlet chamber 5 from top to bottom. A first chamber 6 and a second chamber 7 are arranged in the purification chamber 4. The air inlet 3 Connected to the first chamber 6, one side of the first chamber 6 is provided with a vent hole 61, the vent hole 61 communicates with the second chamber 7, and the outlet of the second chamber 7 communicates with the air outlet chamber 5 , a fan 51 is arranged in the air outlet chamber 5; an ultraviolet light source 8 is arranged in the second chamber 7; an external power supply port 9 is arranged on one side of the purifier housi...

Embodiment 2

[0037] Such as figure 2 As shown, this embodiment provides an air purifier with the function of sterilizing and removing formaldehyde, which is further improved on the basis of Embodiment 1. The second chamber 7 communicates with the air outlet chamber 5 through an air outlet duct 77 , the bottom end of the air outlet duct 77 communicates with the air outlet chamber 5, its main body is arranged in the second chamber 7, the top of the air outlet duct 77 is provided with a lamp panel 75, and the lamp panel 75 is provided with a second ultraviolet light source 71, the second The ultraviolet rays emitted by the second ultraviolet light source 71 are reflected by the second reflector 74 to further enhance the ultraviolet sterilization effect. The setting of the air outlet duct 77 increases the air flow path in the second chamber 7, relatively prolongs the irradiation time of ultraviolet sterilization, and improves the sterilization effect.

[0038] The second photocatalyst contac...

Embodiment 3

[0041] This embodiment provides a kind of air purifier that has the function of sterilizing and removing formaldehyde, such as Figure 4 As shown, the cross-sectional area of ​​the warehouse body of the first chamber 6 is greater than the cross-sectional area of ​​the air inlet 3, and the cross-sectional area of ​​the warehouse body of the second chamber 7 is greater than the cross-sectional area of ​​the air hole 61, and the outside air enters the first chamber through the air inlet 3 In the process of the first chamber 6, due to the sudden increase of the entering space, the incoming air stalls instantaneously, which increases the time for the air to circulate in the purifier. When the same air enters the second chamber 7 through the first chamber 6, The phenomenon of instantaneous stall will also occur, which increases the irradiation time of the ultraviolet light source. In addition, the main body of the air outlet duct 77 is arranged in the second chamber 7, the top of th...

Abstract

The invention discloses an air purifier with sterilizing and formaldehyde removing effects. The air purifier comprises a purifier shell. A top cover is arranged on the top of the purifier shell, air inlets are formed in the periphery of the top cover, the interior of the purifier shell is divided into a purification cavity and an air outflow cavity from top to bottom, a first bin and a second binare arranged in the portion, below the top cover, of the purification cavity, the air inlets communicate with the first bin, a vent hole is formed in one side of the first bin, the vent hole communicates with the second bin, an outlet of the second bin communicates with the air outflow cavity, and a fan is arranged in the air outflow cavity. An ultraviolet light source is arranged in at least oneof the first bin and the second bin. An external power port is formed in one side of the purifier shell. The power input ends of the fan and the ultraviolet power source are connected with the external power port through lines in an integrated manner. The air purifier with the sterilizing and formaldehyde removing effects is long in service life (UVC LED service life is longer than 10,000 H), freeof maintenance and low in use cost.

Description

technical field [0001] The invention belongs to a novel air cleaner with the function of sterilizing and removing formaldehyde used indoors and in cars, and in particular relates to an air cleaner with the function of removing formaldehyde from bacteria. Background technique [0002] At present, most of the air purifiers with bactericidal and formaldehyde-removing effects on the market need to use filters, or negative ions, ozone and other methods to remove bacteria, viruses, formaldehyde, etc. With the extension of use time, the effect will gradually decrease. If the filter is not replaced in time , there will be secondary pollution. Simultaneously, the product cost is high, the structure is complicated, and the service life is short. [0003] This product makes full use of the ability of LED deep ultraviolet light to kill bacteria and viruses and decompose formaldehyde. At the same time, it makes full use of the characteristics of ultraviolet light as the best excitation ...
