Description

Technical Field

[0001] The utility model relates to a structurally improved air purifier, belonging to the technical field of air purifiers. Background Art

[0002] Air purifier, also known as air cleaner, air refresher and purifier, refers to a product that can absorb, decompose or transform various air pollutants and effectively improve the cleanliness of the air.

[0003] Existing air purifiers are usually equipped with a filter, which intercepts dust and particulate impurities in the air. However, the filter is usually detachable. When the filter is used for a long time, dust and particulate matter will adhere to the filter and cause blockage. If the filter is not removed and cleaned in time, the air circulation will be affected, and frequent removal and cleaning of the filter is a cumbersome problem. At the same time, the ultraviolet disinfection lamp in the air purifier is generally equipped with a ballast, which is easy to heat up and cause failure or reduce the service life when working for a long time.

[0004] Therefore, how to provide an air purifier with improved structure which is convenient for replacing the filter and cooling the ballast is the research purpose of the utility model. Utility Model Content

[0005] In view of the deficiencies of the above-mentioned technology, the utility model provides a structurally improved air purifier, in which a pull-out and removable filter is arranged at the bottom of the chassis. When replacing, it is only necessary to pull out the old filter and insert the new filter. At the same time, a funnel is used to guide part of the purified air to the side of the chassis to cool and dissipate heat for the ballast.

[0006] In order to solve the existing technical problems, the technical solution adopted by the utility model is:

[0007] A structurally improved air purifier, characterized in that it comprises a chassis, a pull-out filter is provided at the bottom of the inner side of the chassis, a plurality of groups of ultraviolet disinfection lamps are arranged in an arranged manner in the middle, an axial flow fan is provided on the top, one end of each group of ultraviolet disinfection lamps is electrically connected to a ballast, a side cover is provided on the outer side of the ballast, a secondary air outlet is provided at the bottom end of the side cover, a main air outlet is provided above the axial flow fan, and a connecting funnel is provided on the side above the axial flow fan close to the ballast.

[0008] Furthermore, a bottom of one side of the chassis close to the ballast is provided with a slot for the filter to pass through.

[0009] Furthermore, the bottom of the chassis is arranged as an air inlet, and the front end of the chassis is provided with a front cover.

[0010] Furthermore, the side cover is fixedly mounted on one side of the chassis by screws.

[0011] Furthermore, a plurality of groups of ultraviolet disinfection lamps are arranged from top to bottom inside the chassis.

[0012] The beneficial effects of the utility model are as follows: a plug-in detachable filter is arranged at the bottom of the chassis, and when replacing, only the old filter needs to be pulled out and a new filter needs to be inserted; at the same time, a funnel is used to guide part of the purified air to the side of the chassis to cool the ballast.
