Description

Air purifier

The present invention comprises an air purification technique, in particular a housing having a suction port disposed vertically on the bottom and a discharge port disposed on the upper side, wherein an electric fan installed inside the housing passes through the upper air discharge port. The pressure difference of the convection of air between the low air pressure at the open lower side and the high air pressure at the upper side by sucking air from the open lower air intake port to cause the air intake flow upwards through the longitudinal air passage of the housing To form. When the air flows upwards outside the air exhaust port, it flows upwards at a constant height and then diverges and descends in all directions from the center of the housing. During the continuous operation of the electric fan to draw air, high concentration car exhaust gas, fine dust by the pressure difference of the convection of air between the traction force of the flow of air and the low air pressure on the open lower side of the housing and the high air pressure on the upper side of the housing Particles, hair dust, microfibers, and other harmful industrial odors that fall to the floor or closely float on the floor under the influence of gravity are sucked into the housing by a low pneumatic zone on the open lower side of the housing, It is removed by a replaceable filter unit in the housing, thereby improving the air purification effect. Other air treatments can be installed in the housing to enhance the filtration effect.

With rapid sales and industrial development, industrial and sales activities are concentrated at specific locations. However, exhaust gases from industries, automobiles and other vehicles affect water quality, sunlight and the air around people, threatening human health. However, the air around us contains invisible harmful substances. High concentrations of contaminants such as fine particles of automobile exhaust, tiny hairs, microfiber and industrial exhaust and odorous substances are suspended in the air around the floor, table top and desk top. If left unchecked, these harmful substances would fall on the floor, table top and desk top under the influence of gravity, or float closely on the floor, table top and desk top. When winds or natural winds occur when we walk, harmful substances that accumulate on the floor, table top or desk top, or float closely on the floor, table top or desk top, wind up upwards to the upper level of indoor air. They will be moved together, and people in this realm will breathe in these harmful substances that cause disease.

Many other air purifiers are known and commonly available. Such conventional air purifiers generally use an electric fan that causes circulation of the flow of air through the housing and air filter elements for removing harmful substances from the passing air. Advanced air cleaners or air cleaners will have separate air treatment devices, such as electrostatic precipitators, ionizers, ultraviolet lamps, photocatalyst panels, etc. to enhance air purification or eliminate bacteria. However, conventional air purifiers generally have air intake ports installed at the front and air exhaust ports at the rear for horizontal circulation of air. Another commercial design is known which has upper and lower air intake ports and air exhaust ports disposed on one side for circulation of air. However, the air inlet and outlet port designs of conventional air purifiers have been found to contain harmful fine dust particles, pollen, hair dust and other industrial contaminants accumulating on the table top and desk top or floating on the floor, table top and desk top. It is not possible to draw air from all other directions to effectively bring in odors for processing through the internal air filter elements and the air treatment components. Therefore, conventional air purifiers have low filtration efficiency. In addition, wire mesh filters of conventional air purifiers must be cleaned or replaced after several months of use. This does not mean the high quality of the air, but merely the function of the air purifier to bring in dust particles, flower dust and other contaminants that accumulate on the table top and desk top or float on the floor, table top and desk top. This is because the air cannot be drawn effectively in all directions.

Therefore, it is desirable to provide an air purifier that solves the above problems.

The present invention has been accomplished under such circumstances. It is an object of the present invention to provide an air purifier that effectively purifies air, using an electric fan and air filter elements in the longitudinal air passage that cause the formation of convective flow circulating upwards through the longitudinal air passage.

In order to achieve these and other objects of the present invention, an air purifier includes an air intake port having an open end positioned at a lower side, an air exhaust port located at an upper side of the housing for guiding the inner air out of the housing, and an air intake port.

Subject to the design of air passages extending vertically or substantially vertically, low and high air pressures are applied to the lower and upper sides of the housing during operation of the electric fan to draw air into the housing through the lower air intake port. Each occurs. If the intake stream of air goes upwards outside the air outlet port, the stream of air flows upward at a constant height, and then diverges and descends in all directions from the center of the housing. During the continuous operation of the electric fan to draw air, high concentration car exhaust gas, fine dust by the pressure difference of the convection of air between the traction force of the flow of air and the low air pressure on the open lower side of the housing and the high air pressure on the upper side of the housing Particles, hair dust, microfibers, and other harmful industrial odors that fall to the floor or closely float on the floor under the influence of gravity are sucked into the housing by a low pneumatic zone on the open lower side of the housing, It is removed by the air filter unit.
