Description

Technical Field

[0001] The utility model relates to the technical field of fan equipment, and in particular to a new fan with a filtering mechanism. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. When the fan equipment is in use, during its input and output of air, the residual odor in the internal gas is difficult to be effectively treated during the entry and output of gas. As a result, when the fan equipment is working, the air output is still air with residual odor. The use of the device only plays a transmission role, and the filtering property of the fan equipment is lacking, thus affecting the practicality of the device.

[0003] Patent document CN219413051U discloses a fan "including a fan body, the fan body including an air inlet, a blowing part and an air outlet installed on the air inlet, and also including a filtering device, the filtering device including a filter cartridge, a protective part and a filtering mechanism, the filter cartridge is detachably mounted on the air inlet through a fixing assembly, the air inlet is provided with a mounting opening for installing the filter cartridge, the filter cartridge is used for air intake, the protective part is fixedly arranged on the filter cartridge, the protective part and the filter cartridge are hinged by a hinge, the protective part is used for preliminary filtration of the incoming air, the filtering mechanism is detachably arranged inside the filter cartridge, this fan is convenient for improving the air intake efficiency of the motor fan through the cooperation of the filter cartridge, the protective plate and the filtering mechanism, and is convenient for replacing and disassembling the filter cotton, thereby improving the working efficiency of the fan".

[0004] When the above device is in use, the cooperation of the filter cartridge, the protective plate and the filter mechanism improves the air intake efficiency of the motor fan, and at the same time facilitates the replacement and removal of the filter cotton, thereby improving the working efficiency of the fan. However, the device still has certain shortcomings when in use;

[0005] When the device drives the gas circulation, the gas retains the original odor when the device introduces and outputs the air, so that when the device is used for ventilation, the retained odor problem makes it difficult to ensure the cleanliness of the device when transporting the gas, and the gas retains residual odor inside when it is input and output, which in turn affects the practicality of subsequent use.
