Embodiment Construction
[0024] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0025] Such as figure 1 As shown, a PTC assembly moving device for a cooling fan is arranged in an air duct with an air outlet of the cooling fan, and includes a PTC assembly 1, a drive motor 2, a transmission mechanism 3, and a controller 4. The PTC assembly 1 can It is installed in the air duct of the cooling fan. The output end of the drive motor 2 is connected to the PTC assembly 1 through the transmission mechanism 3. The PCT assembly 1 is driven to move in the air duct by the action of the drive motor 2. The controller 4 and the drive The signal connection of the motor 2 controls the action of the driving motor 2. The driving motor 2 adopts a stepping mo...

The invention discloses a PTC assembly moving device for a cooling fan, the cooling fan and a heating control method thereof. A PTC assembly, a driving motor, a transmission mechanism and a controllerare included. The PTC assembly is movably installed in an air channel. The output end of the driving motor is connected with the PTC assembly through the transmission mechanism. The driving motor acts to drive the PTC assembly to move in the air channel. The controller and the driving motor are in signal connection to control the driving motor to act. The driving motor controls the PTC assembly to move, the rotation angle of the driving motor are controlled and adjusted by the controller, the work state of the cooling fan is controlled, according to the work state of the cooling fan, the rotation angle of the driving motor is controlled, thus movement of the PTC assembly is controlled, heating is conducted when the PTC assembly moves to an air outlet, and heating is stopped when the PTC assembly is reset to the initial position. The structure is simple, overall operation is convenient and quick, assembly efficiency is high, work is stable, response time is short, abrasion between parts is small, service life of the cooling fan is prolonged, and the after-sales repair rate is lowered.
Description
Technical field [0001] The invention belongs to the technical field of fans, and specifically relates to a PTC component moving device for a cooling fan, a cooling fan and a heating control method thereof. Background technique [0002] At present, many cooling fans have two functions, namely cold air and warm air, which are suitable for different solar terms and environments. Compared with the air conditioner, the cooling fan has the advantages of low cost, high efficiency and environmental protection. The PTC assembly composed of the PTC bracket and the PTC heating element fixed in the PTC bracket is one of the most important parts of the cooling fan. The PTC assembly can generally be made Move up and down to touch the tact switch, and then the tact switch controls the work of the PTC component and the motor. In the existing structure, the motor and the heating component are generally transmitted by gear meshing transmission to achieve PTC. The components move up and down, but ...
