[0002] A variable pitch aircraft generally refers to an aircraft that uses a variable pitch propeller or has a similar variable pitch function. The variable pitch propeller is one of the key components of a variable pitch aircraft. It can adjust the installation angle by rotating the blades to adjust its propulsion performance in different operating environments. From an aerodynamic point of view, the use of a variable pitch propeller can significantly improve the efficiency of the propeller, thereby improving the utilization of engine power and the flight performance of the aircraft, including speed, range, ceiling, takeoff run, climb, etc.

[0003] Compared with conventional remote-controlled aircraft, variable-pitch aircraft have more complex structures and functions, and their remote controls require extremely fast response speeds. During long-term use, dust and hand sweat easily adhere to the surface of the remote control, and frequent manual cleaning is troublesome. Failure to clean in time will cause the sticky impurities formed by the mixture of dust and hand sweat to damage the remote control and cause a decrease in sensitivity. Therefore, in response to the above problems, we propose a new type of variable-pitch aircraft control device. Utility Model Content

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the dust cover is rotated to cover the surface of the remote control and the movable baffle is pulled upward to expose the dust outlet. Then, the power switch is pressed to activate the battery to power the fan.

[0024] The effect achieved by the entire embodiment 1 is that the model of the remote controller 1 is MR1SS5. After the frequency is matched with the variable-frequency aircraft by wireless communication, a communication connection is established to control the variable-frequency aircraft. After use, the dust cover 2 can be rotated under the action of the first rotating seat 11 and the rotating column 21 to cover the surface of the remote controller 1. At this time, the control display area of ​​the remote controller 1 is in a sealed state. Then, the handle 31 is pulled upward to drive the movable baffle 3 to move upward. At this time, the dust discharge port 23 on the rear side of the dust cover 2 is exposed, and during the pulling process, the cross bar 32 on the rear surface of the movable baffle 3 will be detached from the lower clamping ring 24 and connected to the upper clamping ring 24, thereby controlling the movable baffle 3. The baffle 3 is fixed, and then the power switch 22 is pressed to start the battery 4 to power the fan 41. When the fan 41 is turned on, an airflow will be formed to blow toward the control surface of the remote control 1 and discharged to the outside through the dust outlet 23. At this time, the dust and hand sweat on the surface of the remote control 1 will be blown out and dried. Finally, the handle 31 is pressed downward to reset the movable baffle 3 and block the dust outlet 23. The design structure is simple and easy to operate. After each use of the remote control 1, it can be dusted and dried in time, thereby avoiding the problem of decreased sensitivity of the remote control 1. The movable baffle 3 is T-shaped as a whole, and the rear side passes through the surface of the dust cover 2, and is connected to the cross bar 32 bracket through a connecting block.

[0025] Example 2: Figure 1-Figure 4 As shown, the connecting mechanism 5 includes a clamping block 503 and a second rotating seat 501, the second rotating seat 501 is fixedly connected to a position near the top of the front surface of the remote control 1, the clamping block 503 is fixedly connected to a position near the top of the front surface of the dust cover 2, a buckle 502 is rotatably connected between the inner surface walls of the second rotating seat 501 via a rotating shaft, an inclined block 504 is fixedly connected to a position near the bottom of the outer surface of the buckle 502, a spring 505 is fixedly connected to the rear surface of the inclined block 504, the rear end of the spring 505 is fixedly connected to the front surface of the remote control 1, and the top of the buckle 502 is engaged with the clamping block 503.

[0026] The effect achieved by the entire embodiment 2 is that when opening the dust cover 2, it is only necessary to press the inclined block 504 to squeeze the spring 505 to contract and drive the top of the block 503 to flip forward, so that the dust cover 2 can be opened upward after losing the connection with the block 503. When closing the dust cover 2, it is only necessary to rotate it downward and press it. At this time, the inclined surface of the block 503 will squeeze the inclined surface of the top of the buckle 502 and flip it to the front side. At this time, the spring 505 is squeezed by the inclined block 504 and contracts. When the block 503 passes over the top of the buckle 502, the spring 505 will rebound and push the buckle 502 to reset, thereby completing the closing and fixing of the dust cover 2. The design structure is simple and stable, which is convenient for opening and closing the dust cover 2 and is more convenient to use.

[0027] Working principle: The remote controller 1 establishes a connection with the variable-pitch aircraft through wireless communication to realize the control of the aircraft. After the operation is completed, the dust cover 2 can be rotated to cover the surface of the remote controller 1 by using the cooperation of the first rotating seat 11 and the rotating column 21, thereby sealing the control display area of ​​the remote controller 1 to prevent dust. Subsequently, the lifting handle 31 drives the movable baffle 3 to rise, exposing the dust exhaust port 23 at the rear of the dust cover 2. During this process, the cross bar 32 on the back of the movable baffle 3 disengages from the lower snap ring 24 and engages with the upper snap ring 24 to stabilize the position of the movable baffle 3. Next, the power switch 22 is pressed to activate the battery 4 to power the fan 41. The fan 41 rotates to generate airflow, which flows through the control surface of the remote controller 1 and is discharged through the dust exhaust port 23, effectively removing dust from the surface of the remote controller 1 and drying hand sweat, keeping the remote controller 1 clean and dry. Finally, the handle 31 is pressed down to reset the movable baffle 3 , reclose the dust outlet 23 to complete the entire dust removal and drying process. This design is simple and efficient, easy to maintain immediately after each use, and effectively prevents the remote control 1 from reducing its sensitivity. In addition, when opening the dust cover 2, it is only necessary to press the inclined block 504 to squeeze the spring 505 to contract and drive the top of the card block 503 to flip forward, so that the dust cover 2 can be opened upward after losing connection with the card block 503. When closing the dust cover 2, it is only necessary to rotate it downward and press it. At this time, the inclined surface of the card block 503 will squeeze the inclined surface of the top of the buckle 502 and flip it forward. At this time, the spring 505 is squeezed by the inclined block 504 and contracts. When the card block 503 passes over the top of the buckle 502, the spring 505 will rebound and push the buckle 502 to reset, thereby completing the closing and fixing of the dust cover 2. This design structure is simple and stable, which is convenient for opening and closing the dust cover 2 and is more convenient to use.
