Technical Field

[0001] The present invention relates to the technical field related to axial flow fans, and in particular to an axial flow fan which is convenient for filtering air impurities. Background Art

[0002] Axial flow fans are mechanical devices used for ventilation and air circulation, which can move large amounts of air conveniently and efficiently. However, existing axial flow fans still have certain defects when used, such as; During use, protective nets are installed at both ends of the axial flow fan, which can not only improve safety but also block debris. However, the gaps in the protective nets are large, and the dust-proof effect of blocking fine impurities and dust is poor, which will cause dust to enter the interior of the axial flow fan and adhere to the blades and joints. Therefore, it needs to be cleaned frequently, which reduces the convenience of use. In order to overcome the above defects, prior art 1 (Chinese patent with application number 202323212601.2 and application date 2023-11-28) is a dust-proof mechanism for an axial flow fan, which solves the problem that the gap of the protective net in the prior art is large and has a good barrier effect on larger particles, but has a poor barrier and dust-proof effect on fine impurities and dust, which will cause dust to enter the interior of the axial flow fan and adhere to the blades and connections, so it needs to be cleaned frequently, reducing the convenience of use. A dust-proof mechanism for an axial flow fan includes a fan, and a dust-proof mechanism is provided at one end of the fan, the dust-proof mechanism includes a docking ring detachably connected to the end of the fan, so as to realize dust-proof protection at the air inlet position of the fan, minimize the dust from entering the interior of the fan, and at the same time, the dust filter can be removed for cleaning, thereby ensuring the air intake while reducing the entry of dust, reducing the frequency of cleaning and improving the efficiency of cleaning; There is also prior art 2 (Chinese patent with application number 202322398323.8 and application date 2023-09-05). An axial flow fan filter mechanism includes a fan body, and a detachable filter screen is provided at one end of the fan body, characterized in that: the fan body includes a fan cylinder, and two mounting grooves are provided at one end of the fan cylinder, and an opening is provided at one side of the fan cylinder at the mounting groove, and an elastic baffle is fixed to one side of the opening, and the detachable filter screen includes a mesh frame, and two mounting plates are fixed to one side of the mesh frame, and a stopper is fixed to one end of the mounting plate, and a handle is fixed to the mounting plate on the other side of the mesh frame, and a square hole is provided at the handle on one side of the mesh frame, and a push rod is inserted into the square hole on one side of the handle; And prior art 3 (Chinese patent with application number 202210470676.1 and application date 2022-04-28) An axial flow fan, comprising a rotating module, a disassembly component, a filter module, a fan body, a maintenance module and a fixed module; a rotatably connected maintenance module is provided on the disassembly component; thereby, it is convenient to drive the maintenance module to be separated from the fan body by the disassembly component, and the maintenance module is driven to rotate by the disassembly component, so that the top of the fan body is hollowed out, making the maintenance and maintenance of the fan body more convenient and quick, greatly improving the efficiency and quality of the maintenance and maintenance of the fan body; the filter module is fixed to the fixed module, and the filter module is in conflict with the fan body. The setting of the filter module is convenient for collecting and processing dust in the airflow, improving the indoor environment, and at the same time, it is convenient to drive the fixed module by the disassembly component, so that the fixed module controls the opening and closing of the filter module and the fan body, thereby making the cleaning and maintenance of the filter module more convenient and quick.

[0003] Although the existing technology can filter impurities in the air, during the working process, the impurities are filtered through the filter, and then the filter is disassembled using a disassembly component to make the filter convenient for cleaning. Therefore, the whole machine needs to be shut down, affecting the overall work efficiency. Frequent disassembly of the filter not only increases the complexity of the operation, but also causes wear of the filter, increasing the cost of maintenance and replacement.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original axial flow fan which is easy to filter air impurities. Therefore, we proposed that the axial flow fan which is easy to filter air impurities can solve the above problems well. Summary of the invention

[0005] The object of the present invention is to provide an axial flow fan which is convenient for filtering air impurities, so as to solve the problem proposed in the above background technology that impurities are filtered through a filter net in the current market, and then the filter net is disassembled using a disassembly component so that the filter net can be easily cleaned. Therefore, the whole machine needs to be shut down, which affects the overall work efficiency. Frequent disassembly of the filter net not only increases the complexity of operation, but also causes wear of the filter net, increasing the cost of maintenance and replacement.

[0006] To achieve the above object, the present invention provides the following technical solution: an axial flow fan for filtering air impurities, comprising a fan body, a motor is connected to the fan body through a support seat, and a blade is connected to the output end of the motor through a rotating shaft; A rotating assembly is installed on the outside of the rotating shaft, and the rotating assembly includes a cleaning plate installed on the outside of the rotating shaft, a brush is arranged on the cleaning plate, a first magnetic block is arranged on the cleaning plate, the cleaning plate is connected to a filter screen through a spring seat, a second magnetic block is installed on the surface of the filter screen, and the brush is driven to rotate on the surface of the filter screen by the rotation of the cleaning plate of the rotating assembly.

[0008] Preferably, the storage box is mounted on the fan body, the airbag output end is connected to a sleeve via a first delivery pipe, the sleeve is mounted on the outside of the rotating shaft, and a through groove is provided on the outside of the rotating shaft.

[0009] Preferably, a first pipe is opened inside the rotating shaft, the first pipe is connected to a second pipe, the second pipe is opened inside the cleaning plate, and an air jet hole is opened on the surface of the cleaning plate.

[0010] Preferably, a sleeve is installed on the outside of the rotating shaft, and a pressure rod is movably connected inside the sleeve. The pressure rod contacts the first delivery pipe after movement. When the rotating shaft rotates, the pressure rod on the outside of the rotating shaft moves from the inside of the sleeve to the outside due to the action of centrifugal force, so that the first delivery pipe can be squeezed by the pressure rod. When the rotating shaft rotates slowly, the pressure rod moves toward the inside of the sleeve, so that the first delivery pipe is opened, which is convenient for gas cleaning operations. When the rotating shaft rotates quickly, the first delivery pipe is squeezed by the pressure rod, which reduces the problem of reduced gas delivery efficiency caused by conflict between air blowing cleaning and gas delivery by the fan body, thereby improving overall practicality.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the axial flow fan is convenient for filtering air impurities, and the brush on the rotating assembly is convenient for cleaning the surface of the filter screen to clean the surface of the filter screen, thereby reducing the problem of reduced impurity filtering efficiency due to a large amount of dust attached to the surface of the filter screen, and the first magnetic block cooperates with the second magnetic block to make the filter screen shake and clean, thereby reducing the problem of reduced work efficiency due to the need for shutdown processing. The specific contents are as follows: The cleaning plate of the rotating assembly rotates to drive the brush to rotate on the surface of the filter, so that the brush on the cleaning plate can clean the surface of the filter, thereby reducing the problem of reduced impurity filtering efficiency due to excessive dust adhering to the surface of the filter and prolonging the service life of the filter. The air bag of the air delivery component delivers the gas to the inside of the sleeve through the first delivery pipe, which facilitates the gas to be delivered through the second pipe, so that the gas is ejected from the jet holes on the cleaning plate, which facilitates the cleaning of dust on the filter screen, thereby greatly improving the overall cleaning efficiency; When the rotating shaft rotates, the pressure rod on the outside of the rotating shaft moves outward from the inside of the casing under the action of centrifugal force, which makes it convenient to squeeze the first conveying pipeline through the pressure rod, thereby reducing the problem of reduced gas transmission efficiency caused by the conflict between the air blowing cleaning and the gas conveyed by the fan body, and improving the overall practicality; The piston of the driving assembly moves laterally, which facilitates the transfer of the liquid inside the delivery cylinder to the inside of the cooling pipe. The overall drive is simple and fast, which reduces the problem of increased costs caused by the need to set up redundant driving structures and facilitates subsequent operation and maintenance. When the eccentric wheel of the driving assembly contacts the pressure plate, liquid is transported to the inside of the cooling pipe. The liquid offsets the heat generated when the motor is in use, thereby performing heat dissipation operations, thereby greatly improving the service life of the motor and reducing the problem of motor damage caused by high temperature inside the fan body.
