Description

Technical Field

[0001] The utility model relates to the technical field related to crossflow fans, in particular to a crossflow fan which is easy to disassemble. Background Art

[0002] A crossflow fan is also called a crossflow fan. The impeller is multi-blade, long cylindrical, and has forward multi-wing blades. When the impeller rotates, the airflow enters the blade grid from the opening of the impeller, passes through the inside of the impeller, and is discharged into the volute from the other side of the blade grid to form a working airflow. The flow of air in the impeller is very complicated, and the airflow velocity field is unstable. There is also a vortex in the impeller with the center located near the volute tongue.

[0003] In the prior art, when a cross flow fan is used, it is mostly directly fixed and installed at a desired position by bolts. When it is necessary to replace or repair it, it is not convenient to disassemble it. Therefore, a cross flow fan that is easy to disassemble is needed. Utility Model Content

When the cross-flow fan needs to be disassembled, the motor is started, and the motor drives the second reciprocating screw to rotate, thereby driving the fixed plate to move. When the fixed plate moves, it drives the rack to move. When the rack moves, it drives the gear meshing with it to rotate, thereby driving the threaded rod to rotate, thereby driving the sleeve to move. When the sleeve moves, it drives the cross plate to move. When the cross plate moves to above the blocking plate in the mounting groove, the fixed box can be pulled to separate it, and then the cross-flow fan can be removed.

[0012] By adopting the above technical solution, when the first reciprocating screw rotates, it drives the moving block to move back and forth, thereby driving the cleaning plate to move back and forth.

[0013] Optionally, an air inlet slot is provided on the fan body, a filter plate is provided on the air inlet slot, and the cleaning plate is against the filter plate.

[0014] By adopting the above technical solution, the dust on the filter plate can be cleaned by the back and forth movement of the cleaning plate.

[0015] Optionally, a second reciprocating screw is fixedly mounted on the motor, a fixing plate is threadedly mounted on the other end of the second reciprocating screw, and a rack is fixedly mounted on the fixing plate.

[0016] By adopting the above technical solution, the motor is started, and the motor drives the second reciprocating screw to rotate, thereby driving the fixed plate to move, and the fixed plate drives the rack to move when it moves.

[0017] Optionally, the rack is meshed with a gear, a threaded rod is fixedly mounted on the gear, and a sleeve is threadedly sleeved on the threaded rod.

[0018] By adopting the above technical solution, when the rack moves, it will drive the gear meshing with it to rotate, thereby driving the threaded rod to rotate, and thus driving the sleeve to move.
