(21) Further, the toy aircraft further includes a spraying assembly 6, where the spraying assembly 6 includes a water tank 61 and an atomizer 62. The water tank 61 is arranged in the main body 1 and located at the bottom of the main body 1, a through hole for mounting the atomizer 62 is formed in a lower end surface of the water tank 61, and the bottom of the main body 1 is provided with a plurality of supporting legs 13 distributed circumferentially.

(22) The working manner of this disclosure is described as follows: according to the toy aircraft adopting the structure, the battery box 21 in the main body 1 supplies power to the motor set 23 on the motor seat 22, and a switch arranged on the main body 1 is used for opening and closing the battery box 21. Since the content belongs to the prior art, a redundant description of how to implement power supply will not be given here. The motor set 23 is detachably mounted on the motor seat 22. Preferably, the motor seat 22 is provided with a mounting seat for mounting the outer motor 231 and the inner motor 232. Both the outer motor 231 and the inner motor 232 are arranged vertically, and the outer gear 241 and the inner gear 242 are transversely arranged in parallel. The inner gear 242 is located below the outer gear 241 and is rotatably connected to the bottom of the motor seat 22, and the output ends of the outer motor 231 and the inner motor 232 are in meshing connection with the outer gear 241 and the inner gear 242, respectively.

(23) To drive the first rotating blade 31 and the second rotating blade 34 to rotate in different directions in a starting process of the motor set 23, a connecting column is vertically arranged at the bottom of the motor seat 22 and extends upwards vertically, the first rotating cylinder 33 is sleeved on the connecting column and is connected to the motor seat 22 through a bearing 7, the upper end of the first rotating cylinder 33 is embedded and fixed in the first rotating shaft 32, and the lower end of the first rotating cylinder 33 is embedded and fixed in the outer gear 241. Therefore, in a process of starting the outer motor 231, the outer gear 241 meshed with the outer motor is driven to rotate, so that the first rotating shaft 32 is driven to rotate, the first rotating blade 31 rotatably connected to the outer side wall of the first rotating shaft 32 rotates, and at least two groups of first rotating blades 31 with the first rotating shaft 32 as a symmetric center rotate under the action of centrifugal force; and the second rotating cylinder 36 is also sleeved on the connecting column and located in the first rotating cylinder 33, the second rotating cylinder 36 is connected to the first rotating shaft 32 and the outer gear 241 through a bearing 7, respectively, the upper end of the second rotating cylinder 36 is embedded and fixed in the second rotating shaft 35, and the lower end of the second rotating cylinder 36 is embedded and fixed in the inner gear 242. Therefore, when the inner motor 232 is started and a rotation direction opposite to the outer motor 231 is kept, the inner gear 242 meshed with the inner motor is driven to rotate, so that the second rotating shaft 35 is driven to rotate, the second rotating blade 34 rotatably connected to the outer side wall of the second rotating shaft 35 rotates, at least two groups of second rotating blades 34 with the second rotating shaft 35 as a symmetric center rotate reversely under the action of centrifugal force, the effect of simultaneous reverse rotation of the double-layer rotating blades is achieved, the reverse torsion force caused by the double-layer rotating blades is counteracted, and stable up-down flight is achieved.

(24) The lift-off effect caused by simple reverse rotation of the double-layer rotating blades is still unstable, and the reason lies in that the air under synchronous rotation is pressurized and turbulent, which causes the aircraft to swing left and right, and the flight state is unstable. Therefore, through at least two groups of balance rods 38 which are mounted on the second rotating shaft 35 and are symmetrical to each other, the balance rods 38 are synchronously driven to rotate in the rotating process of the second rotating blade 34, and the counterweight block 381 at the end portion of the balance rod 38 can effectively provide stronger centrifugal force, so that left-right transverse swing force caused by turbulence is counteracted, and stable up-down flight of the aircraft is ensured. The stabilizing rod 39 is arranged to fix the connection between the second rotating shaft and the balance shaft 37.

(25) Since the lift-off effect of the double-layer rotating blades moves up and down, horizontal transverse movement cannot be achieved without external force. Thus, the fixed seat 51 is arranged at an upper end of the connecting rod 4, the traveling rotating blade 53 is vertically arranged on the transverse air duct 54 in the fixed seat 51, and the traveling rotating blade 53 is driven by the traveling motor 52, and therefore, when the aircraft is in a hovering state, the aircraft can be assisted in transverse displacement by starting the traveling rotating blade 53, thereby achieving the flight effect in each of the up-down, left-right, front-back directions.

(26) Due to the flight effect of the aircraft moving up and down, left and right, and front and back, which is similar to a starship, the first surrounding wall 11 is arranged on the first rotating shaft 32, the second surrounding wall 12 is arranged on the second rotating shaft 35, the first surrounding wall 11, the second surrounding wall 12, and the main body 1 are coaxial up and down and form a continuous cylindrical shell structure, and an outer portion of the fixed seat 51 is of a cone structure folded upwards. Meanwhile, the supporting legs 13 are arranged at the bottom of the main body 1, so that the overall appearance is like a starship hovering during launch, which is more attractive to children to play with it.

(27) Since the appearance has presented the effect of the starship, the absence of a flame-like jet effect during hovering will appear that the toy is not real enough. Therefore, a water tank 61 is arranged at the bottom of the main body 1. The bottom of the water tank 61 is sprayed by an atomizer 62, and when necessary, a bulb, preferably a red bulb, is added to the bottom of the water tank 61. When the atomizer 62 and the bulb are started, the double-layer rotating blades are started at the same time to assist the main body 1 to lift off, a simulation effect similar to starship launching can be achieved, making the toy more interesting. In addition, after completing hovering flight, the aircraft can perform in-place landing, and after landing, the first rotating blade 31, the second rotating blade 34, and the balance rod 38 on the aircraft are folded downwards under the action of gravity, without taking up space when not started.

(28) Beneficial effects of this disclosure are as follows: the outer motor 231 and the inner motor 232 are mounted and the outer gear 241 and the inner gear 242 are driven, respectively, so that the effect of simultaneous reverse rotation of the double-layer rotating blades is achieved, the reverse torsion force caused by the double-layer rotating blades is counteracted, and stable up-down flight is achieved. To counteract the left-right transverse swing force caused by turbulence, and ensure stable up-down flight of the aircraft, a balance rod 38 synchronously rotating with the second rotating blade 34 is arranged, so that more stable up-down flight is achieved, meanwhile, transverse displacement of the aircraft is achieved through arrangement of the traveling rotating blade 53, and finally the flight effect in each of the up-down, left-right, front-back directions is achieved. Meanwhile, in cooperation with the atomizer 62 and the bulb, a simulation effect similar to starship launching can be achieved, making the toy more interesting.

Although this disclosure has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that the technical solutions recited in the above embodiments may still be modified, or some or all of the technical features thereof may be replaced with equivalents.
