Household air purifier

Abstract

The invention belongs to the technical field of purifiers, and particularly relates to a household air purifier. The household air purifier comprises a main body, a fan, an air cylinder and a controller, wherein a group of hollow plates are arranged in the main body, the main body is divided into a first cavity, a second cavity and a third cavity by means of the hollow plates, a group of first filter elements, a group of second filter elements and a group of negative ion generators are arranged in the main body, a group of second air outlet grids are fixedly connected to the front side wall and the rear side wall of the main body, and each second air outlet grid communicates with the second cavity. According to the household air purifier, through cooperation of the first cavity and the third cavity, a contact area of dust-containing air and the first filter elements and a contact area of the dust-containing air and the second filter elements are increased, so that dust in the dust-containing air can be rapidly removed, a dust content in the air is reduced, the quality of the air is improved, purified air is uniformly conveyed to the periphery of the main body by means of a first air outlet grid and the second air outlet grids, then the quality of the air around the main body can be quickly improved, and harm of the dust-containing air to human health is reduced.

Description

technical field [0001] The invention belongs to the technical field of purifiers, in particular to a household air purifier. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decorations that can absorb, decompose, or transform various air pollutants, generally including PM2.5, dust, pollen, odor, and formaldehyde.

[0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to decorations that can absorb, decompose, or transform various air pollutants, generally including PM2.5, dust, pollen, odor, and formaldehyde. Pollution, bacteria, allergens, etc., products that can effectively improve air cleanliness are mainly divided into household, commercial, industrial and building; air purification technologies commonly used in the market currently include adsorption technology, plasma catalytic purification technology, electrostatic dust removal technology, photocatalyst technology, etc., but the existing air purifiers have insufficient air purification effect, low air purification efficiency, single wind outlet angle, and a lot of dust in the air in the environment, such as in the northwest of my country, where the climate is dry and there is a lot of sand and dust. The dust content in the environment is relatively high, which makes the dust on the filter screen easy to accumulate, which can easily cause the filter screen to be blocked and difficult to clean the filter screen. Frequent replacement of the filter screen is required. To replace the filter screen, the air purifier needs to be disassembled, and the whole process is time-consuming and laborious. , affecting the purification effect of dust in the air

[0003] There is also a patent about a household air purifier in the prior art. For example, a Chinese patent with the application number CN2017112354443 discloses a household air purifier, which includes an air inlet, a housing, a channel and an air outlet. An air inlet channel is installed on the right side of the air inlet, and an air intake fan is installed in the air inlet channel, an electrostatic dust filter device is installed in the channel, and an anion purifier is installed on the right side of the electrostatic precipitator filter device, and the anion purifier An activated carbon filter layer is installed on the right side, an air outlet channel is installed on the right side of the air outlet, and an air outlet fan is installed in the air outlet channel, a power cord is installed on the lower side of the housing, and a bracket is installed on the lower side of the housing. A power switch is installed on the surface of the housing, and a heating pipe switch is installed on the right side of the power switch, and a water injection port is installed on the right side of the heating pipe switch. The invention can detect the quality of the air at any time by installing an air detector in the housing. Guarantee real-time monitoring; however, there are deficiencies in this technical solution. For example, due to climate reasons in the northwest of China, the climate is relatively dry, the dust content in the environment is high, and it is easy to fall ash in the family environment. When the dust content in the air in the family environment is high For a long time, the electrostatic dust removal filter device of the air purifier has poor trapping effect on larger particles and fibers, which will cause discharge, and the cleaning is troublesome, time-consuming and laborious, and it is difficult to quickly reduce the dust content in the air, and it is difficult to quickly improve the air quality in the home environment
