Description

Air purifier and air purification cartridge

The invention relates to an air purifier and an air purification cartridge, in particular to an air purifier having an air purification cartridge and sterilizing by ultraviolet irradiation.

Air purifier refers to a product that can adsorb, decompose or transform various air pollutants and effectively improve air cleanliness. The pollutants handled include not only harmful chemical gases such as PM2.5, dust, odor, formaldehyde, but also microorganisms such as germs and allergens.

As people pay more attention to their own health and air quality, various indoor air purifiers have developed rapidly in recent years. Among them, ultraviolet light air purifiers used to sterilize bacteria, allergens and other microorganisms in indoor air are also Has been widely used.

However, the existing ultraviolet light air purifier usually installs the ultraviolet lamp at the air outlet of the rear section of the air purifier, and the air flow rate at the air outlet is very fast, which may cause the problem of unsatisfactory sterilization effect.

Therefore, the main purpose of the present invention is to provide an air purifier and an air purification cartridge to solve the above-mentioned problems.

The object of the present invention is to provide an air purifier and an air purifying cylinder, which can avoid the breeding of bacteria, greatly improve the purification effect of the air purifier, and have a simple structure and low cost.

The invention relates to an air purifier. The air purifier includes an outer tube, an inner tube, a filter assembly, a first ultraviolet irradiation device, and a second ultraviolet irradiation device. The inner tube is arranged in the outer tube, and the space between the outer tube and the inner tube is the first space. The inner cavity of the barrel is the second space.

The inner cylinder has a channel to communicate with the first space and the second space. The filter element is covered and arranged in the channel to filter out impurities in the air, but it also reduces the air flow rate. The first ultraviolet irradiation device is arranged in the first space and adjacent to the outside of the filter assembly, and the second ultraviolet irradiation device is arranged in the second space and adjacent to the inside of the filter assembly. Therefore, both the inside and the outside of the filter assembly can be irradiated by ultraviolet rays for sufficient sterilization.

Air will enter the first space from the outside of the air purifier, continue to pass through the filter assembly, enter the second space, and then leave the air purifier. The flow rate of the air through the filter assembly will slow down, so there can be more time to Ultraviolet rays are fully sterilized.

Furthermore, the cross section of the outer cylinder may be square, and the first ultraviolet irradiation device may be arranged at the corner of the square of the cross section of the outer cylinder.

To further illustrate, the filter assembly may include primary filter cotton, harmful gas filter cotton or activated carbon filter cotton.

The controller is electrically coupled to the first ultraviolet irradiation device and the second ultraviolet irradiation device for controlling the intensity of the ultraviolet irradiation.

In order to achieve at least one of the advantages or other advantages, another embodiment of the present invention may provide an air purification tube, including an outer tube, an inner tube, a first lamp holder, and a second lamp holder. Inner cylinder Placed in the outer cylinder, the space between the outer cylinder and the inner cylinder is the first space, the inner cavity of the inner cylinder is the second space, and the inner cylinder has a channel to communicate the first space and the second space. The first lamp socket is arranged in the first space, and the second lamp socket is arranged in the second space.

During operation, air will enter the first space from the outside of the air purifier, then pass through the channel, enter the second space, and then leave the air purifier.

To further illustrate, the air purification cylinder further includes a filter assembly, a first ultraviolet irradiation device, and a second ultraviolet irradiation device. The filter assembly is covered and arranged in the channel, and the first ultraviolet irradiation device is assembled on the first lamp holder to be arranged in the first space. And adjacent to the outside of the filter assembly, the second ultraviolet irradiation device is assembled on the second lamp holder so as to be arranged in the second space and adjacent to the inside of the filter assembly. Therefore, both the inside and the outside of the filter assembly can be irradiated by ultraviolet rays to be fully sterilized, and further, the flow rate of the air passing through the filter assembly is slowed down, so there is more sufficient time to fully sterilize with ultraviolet rays.

Therefore, the present invention provides an air purifier and an air purifying cartridge. The ultraviolet irradiation device is installed on the inside and outside of the filter assembly, where the air flow rate is slow and dirt is easy to accumulate, which can improve the sterilization efficiency, and the reflector is installed on the One side of the ultraviolet irradiation device can improve the utilization rate of ultraviolet rays, so the air purifier and the air purification cylinder of the present invention can greatly improve the air purification effect, and have a simple structure and low cost.
