Description

air purifier

The present invention relates to an air purifier, and in particular refers to an invention that can prevent filtered air from being sucked into the air purifier again immediately.

Exhaust gas will be emitted when the vehicle is moving, and exhaust gas will be emitted during the production process of the factory, or it will also be generated when the thermal power plant is performing power generation operations, or it will be caused by the cold high pressure going south, causing neighbors If the air pollutants from the country are brought to the country, then there is a chance to cause serious air pollution along the western coast of the island; generally speaking, exhaust gas or air pollutants refer to carbon monoxide, nitrogen dioxide, ozone, suspended particles, etc. If the human body grows Exposure to air pollutants for a long time will affect health such as respiratory diseases, chest tightness and even life safety.

In order to prevent health from being harmed by air pollutants, there is the Republic of China Patent Publication No. M631974 "Multidirectional Air Purifier", which includes an outer shell, an inner shell, a filter and a fan. The outer casing is provided with a plurality of first air holes, and the first air holes are perforated on the periphery of the side wall of the outer casing, and there is a receiving space in the outer casing; the inner casing is arranged in the receiving space, and the inner casing is provided with a plurality of first air holes corresponding to Two air holes, the second air hole is pierced on the side wall periphery of the inner shell, the inner shell divides the accommodation space into a filter space and an air collection space, the filter space is sandwiched between the outer shell and the inner shell, and the air collection space is set In the inner shell; the filter ring is set in the filter space; the fan cover is set on the top side of the outer shell and the inner shell, the fan makes the external air flow pass through the filter space to the air collection space from multiple directions, and is guided by the fan out.

However, the direction of the airflow before and after filtration in the previous proposal is set at 90 degrees, and the filtered airflow may still be sucked into the air purifier again when it flows, which will affect the efficiency of the clean airflow. Republic of China Patent Announcement No. M610141 "Filter Fan", which includes a net body, an air supply device, a base and a filter body, wherein the filter body can be arranged on the outer surface of the net body, and through the filter body set The filter element enables the air supply device to achieve the purpose of filtering air during the air supply operation. In addition, because the net body is pivotally equipped with a base, the net body can achieve the purpose of adjusting different blowing angles.

However, although the airflow direction before and after filtration in the above-mentioned prior art is the same and located at opposite ends, there is no clear boundary between the air inlet and the air outlet, and the airflow may still flow freely and affect the efficiency of the clean airflow.

Furthermore, such devices often need to be operated for a long time. Under long-term use, the motors that drive the fans or blades are often damaged. When the motors are damaged, the entire set must be replaced, which is not economical.
