Shaftless fan blade mechanism capable of concentrating wind

This creation is about the fan blade mechanism, especially a shaftless fan blade mechanism that can concentrate wind.

The conventional fan structure mainly includes a plurality of blades connected to a rotating shaft, wherein the plurality of blades extend outward from the rotating shaft, and when the driving mechanism of the rear end drives the rotating shaft to rotate, the plurality of blades can be rotated and then rotated. The plurality of blades are used to cut the surrounding airflow to produce a wind beam in a particular direction.

However, in the fan structure of the prior art, the blades are all around the rotating shaft, so when the blade rotates, the wind force near the axial direction of the rotating shaft is smaller, so that the overall wind beam will diverge outward, and There is no concentrated and powerful wind, so the overall wind effect is quite insufficient. Therefore, the applicant hopes that through the simple fan blade design, the fan blade can generate concentrated and powerful wind when it rotates to meet the needs of use.

Therefore, the present invention hopes to propose a new shaftless fan blade mechanism capable of concentrated wind to solve the above-mentioned prior art defects.

Therefore, the purpose of the present invention is to solve the above-mentioned problems in the prior art.

Therefore, the wind beam flows from one end of the annular frame to the other end. In this case, since the fan blade extends toward the center of the annular outer frame, the wind blown out is concentrated in the central axial direction of the annular outer frame, and the effect of wind concentration is generated, and a strong and concentrated wind beam is blown out. Therefore, the disadvantage that the conventional fan cannot produce concentrated and powerful wind power can be solved.

In order to achieve the above object, a shaftless blade mechanism capable of concentrated wind is proposed in the present invention, comprising: a shaftless impeller comprising an annular outer frame and a plurality of segments, the plurality of segments being connected The inner wall of the annular outer frame extends from the inner wall of the annular outer frame toward the center of the annular outer frame; the outer wall of the annular outer frame forms a plurality of driving pieces; and a driving structure for driving the plurality of driving Rotating the piece to drive the annular outer frame to rotate, so that the plurality of segments in the annular outer frame also rotate to generate a wind beam; therefore, the wind beam flows from one end of the annular outer frame to the other end; The fan blades extend toward the center of the annular outer frame, so that the blown wind is concentrated in the central axial direction of the annular outer frame, and the effect of wind concentration is generated.

The outer wall of the annular outer frame 11 forms a plurality of driving pieces 15. When the external wind blows in the annular direction of the outer portion of the annular outer frame 11, the plurality of driving pieces 15 can be blown to rotate, and the annular outer frame 11 is driven to rotate, and the inner annular frame 11 is more The fan blades 12 are also rotated, so that the wind is from the ring frame One end of 11 flows to the other end to generate a wind beam.

A driving structure 20 is configured to drive the plurality of driving pieces 15 to rotate, and drive the annular outer frame 11 to rotate, so that the plurality of segments 12 in the annular outer frame 11 also rotate to generate a wind beam. Therefore, the wind beam is caused to flow from one end to the other end of the annular outer frame 11. In the present case, since the plurality of segments 12 extend toward the center of the annular outer frame 11, the wind blown out is concentrated in the central axial direction of the annular outer frame 11, and the effect of wind concentration is generated.

The motor blade group 40 includes a motor 51 and a spindle with the motor 51. 411 is coupled to a plurality of blades 42. The figure shows that the plurality of blades 42 extend directly from the mandrel 411 of the motor 51, such as the structure of a conventional electric fan. However, the present invention is not limited to this configuration, and any structure in which the blade 42 is coupled to the motor 51 and driven to rotate by the motor 51 is within the scope of the present invention. The motor blade set 40 drives the plurality of blades 42 to rotate via the motor 51, and external wind can be driven from the lower side inlet end 31 of the air guiding structure 30 to the outlet end 32 of the wind guiding structure 30.

When the wind from the motor blade set 40 follows the side of the wind guiding structure 30 When the plurality of driving pieces 15 driving the outside of the annular outer frame 11 are driven, the circular outer frame 11 is driven to rotate, and the plurality of segments 12 in the annular outer frame 11 are also rotated. Therefore, the wind is caused to flow from the upper side inlet end 32 to the outlet end 33, while blowing a strong and concentrated wind beam.

4 shows a second embodiment of the present invention in which a plurality of shaftless impellers 10 are arranged in series, so that the axial wind beam blown by the shaftless impeller 10 of the previous stage is further divided by the second stage. The shaftless impeller 10 accelerates, making the axial wind beam faster and more windy. Therefore, the axial arrangement of the plurality of shaftless impellers 10 can be used to sequentially strengthen the wind force to achieve a concentrated and powerful wind beam effect.

The above-mentioned series structure of the present invention can be used to push the injection engine, because in the series structure, the wind passes through a plurality of shaftless impellers 10 connected in series, so the wind is extremely strong, and when entering the injection engine, the surrounding air can be rapidly entered into the injection engine. Medium, therefore, can produce excellent results of rapid explosion. Since the wind is concentrated in the central portion of the flow path, the forging requirements for the metal or its alloy located around the flow path can be much lower than that of the conventional art injection engine, thereby achieving the purpose of improving efficiency and reducing cost.

Therefore, the wind beam is caused to flow from one end to the other end of the annular outer frame 11. In the present case, since the plurality of segments 12 extend toward the center of the annular outer frame 11, the wind blown out is concentrated in the central axial direction of the annular outer frame 11, and the effect of wind concentration is generated.

The drive structure 20 includes a motor drive gear set 50. The motor drive gear set 50 includes a motor 51 and a gear set 52 coupled to the spindle 511 of the motor 51. The gear set 52 includes at least one gear 521. . The figure shows that the gear set 52 is coupled to the mandrel 511 of the motor 51. Each of the driving pieces 15 is formed on the outer wall of the annular outer frame 11 in an equidistant manner, so that the plurality of driving pieces 15 can be coupled to the gear set 52 via meshing. When the motor drive gear set 50 drives the gear set 52 to rotate via the motor 51, the plurality of drive pieces 15 are driven to rotate.

When the motor drive gear set 50 drives the plurality of drive pieces 15 outside the annular outer frame 11, the annular outer frame 11 will be driven to rotate, and the plurality of segments 12 in the annular outer frame 11 are also Follow the rotation. Therefore, the wind is caused to flow from one end of the annular outer frame 11 to the other end, and a strong and concentrated wind beam is blown out.
