Description

air purifier

technical field

The invention relates to a machine for cleaning the air.

Background technique

Due to the rapid development of industry and commerce, various industrial production and human commercial activities are frequent and concentrated, but the smoke emitted by industries and vehicles and other vehicles has seriously polluted the water, sunlight and air that human beings rely on for survival. Human health has been seriously affected, and the air is indispensable for human beings to survive every minute and every second. However, due to serious pollution in the current air, there are various harmful substances invisible to the eyes or high concentrations floating close to the ground. , desktops and countertops, car exhaust dust particles, hair, fibers, and various industrial pollution harmful smoke smells and other sundries, and when there is no wind in a static state, these harmful substances will be due to gravity (gravity) Therefore, the concentration of polluted air is generally the highest near the ground and the table. When we walk around, the flowing wind or the natural wind outside, The harmful substances that have fallen and accumulated on the ground, table or countertop will be lifted up and permeated in the air. Therefore, human beings have been inhaling these harmful substances in various places and spaces, and various diseases have been produced.

Therefore, at present, human beings have designed various air cleaners for clean air to improve the quality of the air, and rely on additional equipment such as filtration, sterilization and deodorization to achieve the purpose of cleaning the air, but the existing air cleaners , most of its air inlets and outlets are designed in a horizontal direction. Even if there are upper and lower air inlets and air outlets, they are only located on one side of the air cleaner. Although it can produce air suction, filtration and discharge However, due to the design of the position of the air inlet and outlet, the existing air purifiers cannot deal with a large number of high-concentration fine dust particles, pollen, dander and various kinds of dust particles that fall and accumulate or float on the ground, desktop or countertop in all directions. Harmful smoke and other harmful substances polluted by industrial nature cannot be effectively filtered and removed. Therefore, due to the poor filtering effect of various air purifiers currently on the market, most of the filters need to be cleaned after several months of use. This phenomenon does not mean that the air quality is good, but that the design of the existing air purifiers cannot effectively filter the fine dust particles, pollen and dander that accumulate and float on the ground, desktop or countertop, and the ion device used in it makes the Dust, pollen, smoke, etc. in the air are charged (static electricity) and are easily attracted to the ground and precipitated. Even with various additional functions of decomposition, deodorization and sterilization, it is impossible to effectively solve the aforementioned falling accumulation or a large number of high Concentration of fine dust particles, pollen, dander floating on the ground, desktop or countertop, as well as harmful smoke smell or toxic gas and smoke from various industrial and natural pollutions.

Wherein: fans are arranged above and below the housing.

Wherein: the fan is arranged at any position in the housing.

Wherein: the fan is assembled at the air outlet end on the top of the housing in a detachable manner.

Wherein: the fan is placed in a fan cover, and the fan cover is set at the air outlet on the top of the casing.

Wherein: the housing has a central axis, the central axis is set obliquely to the ground, and the air inlet of the housing is located at the bottom of the housing and faces the ground.

Wherein: a plurality of ventilation holes are provided on the outer lower surface of the housing to form the air inlet.

Wherein: a plurality of strip-shaped ventilation holes are provided on the lower peripheral surface of the casing to form the air inlet.

Compared with prior art, the beneficial effect that the present invention has is:

1. By means of the above-mentioned shell which is longitudinally perpendicular to the ground, a longitudinal air flow channel is formed in the center of the shell, the air inlet is set at the bottom of the shell, and the air outlet is set at the top of the shell. The set fan sucks air from the lower air inlet, and forms a low-pressure area at the above-mentioned place, attracting polluted air from all directions to flow to it, and the air is blown upward through the upper air outlet through the longitudinal air flow channel inside the housing , and then form a high and low pressure difference air convection phenomenon, and after the air is blown upwards from the air outlet, the air will diffuse and descend around the shell around the center, and then rely on the fan to continuously suck the air from the air inlet below to form The traction effect of the airflow forms a continuous microcirculation convection phenomenon of high and low pressure indoor air. With this convective air, a large number of high concentrations can be dropped due to gravity (gravity) and float close to the ground, desktop and The fine dust particles, hair, fibers and various industrial pollution and harmful smoke smells on the countertop are sucked into the housing, and are filtered out by the replaceable filter unit in the housing, thereby effectively improving the effect of air purification and forming a Low energy consumption and high efficiency air purifier.

2. The present invention has been made into a sample and actually tested for use. After 48 hours of use, the filter unit has absorbed dust particles, hair, fibers and various industrial pollution and harmful smoke smells. Therefore, its filter unit The effect is excellent.
