Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to the technical field of displacement positioning fans. Background Art

[0002] Fans drive airflow, removing heat from the human body through the flowing airflow, achieving a cooling effect. Traditional fans only provide cooling, but because the airflow is high at high speeds, prolonged fan use can cause headaches and other discomfort. At low speeds, the airflow is low, failing to achieve rapid heat dissipation. Utility model patent application number CN00245799.7 discloses an electric fan with a conveniently changeable housing design. This fan utilizes a structure that separates the fan housing cover from the housing. This allows the fan to be customized by simply adding different housing covers. Thus, a variety of electric fans can be produced simply by adding different housing covers to the same fan housing. This reduces mold manufacturing costs and shortens production cycles. The reduced cost of manufacturing new fan designs allows manufacturers to offer a wider range of fan designs. However, this approach does not address how to achieve adaptive fan blades, ensuring consistent air flow and a similar blowing effect regardless of the fan's speed. Summary of the Invention

DETAILED DESCRIPTION

[0019] See Figure 1 and Figure 2The present invention provides a displacement positioning fan, comprising a motor 1, a fixing base 2, a limited sliding turntable 3, a rotating cylinder 4, a rotating blade 5, an inclination reset mechanism 6, a dust collector 7 and an inclination linkage mechanism 8. The upper side of the motor 1 is provided with a fixing base 2 for fixing the fan on the roof, the rotating shaft of the motor 1 is fixedly provided with a limited sliding turntable 3, the internal part of the limited sliding turntable 3 is provided with an inclination linkage mechanism 8, at least two rotating cylinders 4 are provided around the inclination linkage mechanism 8, and the lower side of the rotating cylinder 4 is provided with a rotating mechanism for driving the rotating cylinder 4. The rotating drum 4 rotates the rotating blade 5 with automatically adjusted inclination. The end of the rotating drum 4 is provided with a dust collector 7 for collecting dust. The limit sliding turntable 3 is provided with an inclination reset mechanism 6 for resetting the inclination of the rotating blade 5. In the blowing mode, the limit sliding turntable 3 is driven by the motor 1 to rotate. The rotating blade 5 rotates under the drive of the limit sliding turntable 3. The air is pushed downward by the rotating blade 5. Due to the air resistance, the angle of the rotating blade 5 will be adaptively flipped. Under the action of the inclination linkage mechanism 8, all the rotating blades are The rotating blades 5 move synchronously. The higher the speed of the fan, the greater the angle of rotation of the rotating blades 5, and vice versa. When the speed is reduced or stopped, under the action of the inclination angle reset mechanism 6, the angles of all the rotating blades 5 will be reduced synchronously. That is, in the low speed mode, the amount of air pushed by the surface of the rotating blades 5 is large, but the speed is low. In the high speed mode, the amount of air pushed by the surface of the rotating blades 5 is small, but the speed is fast. This can maximize the efficiency of the fan-driven air flow. At the same time, for some people who get a headache when blowing at high wind speeds, they can choose the low wind speed mode to achieve the effect of cooling through a large amount of air flow. At the same time, the wind speed is low. The rotating blades 5 in the dust removal mode rotate in the opposite direction, and the fan pushes the air upward. Under the guiding action of the rotating blades 5, the air is introduced into the dust collector 7. Under the action of centrifugal force, the dust is confined in the dust collector 7. When it is hot, this fan can drive the air flow downward to achieve the purpose of cooling the human body, and drive the air flow upward to remove dust in the air. The fan utilization rate is high and the value of the fan can be maximized.

[0020] like Figure 1 and 2 As shown, the fixing base 2 includes a fixing plate 21 and a connecting rod 22. One end of the connecting rod 22 is fixed to the motor 1, and the other end is fixed to the fixing plate 21. The fixing plate 21 is provided with a fixing hole. The fixing plate 21 is fixed to the roof using expansion screws through the fixing hole. Since this fan collects dust through centrifugal force, it can only be fixed on the roof, that is, to keep the rotating cylinder 4 rotating in the horizontal plane. Figure 3 As shown, the limited sliding turntable 3 includes a turntable seat 31 and a turntable cover 32. The turntable seat 31 is cylindrical with an open upper end, and the upper end of the turntable seat 31 is fixedly connected to the turntable cover 32 by bolts.

[0021] like Figure 5 As shown, the rotating drum 4 is provided with a dust filter air inlet 41, which is located on the back side of the rotation direction in the blowing mode. The dust filter air inlet 41 is located on the upper side of the rotating blade 5. The fan is divided into a blowing mode and a dust removal mode. The blowing mode drives the air to flow downward by rotating the rotating blade 5. The dust removal mode drives the air to flow upward by rotating the rotating blade 5 in the opposite direction, and at the same time, the dust is recovered under the action of centrifugal force. Figure 4 As shown, the inclination linkage mechanism 8 includes a linkage shaft 81, a linkage gear 82, a linkage toothed disc 83, an inclination limiting movable column 84 and an inclination limiting fixed column 85. The linkage shaft 81 is laterally arranged on the turntable seat 31, the linkage gear 82 is arranged on the linkage shaft 81, the linkage toothed disc 83 is arranged at the bottom of the turntable seat 31, the linkage gear 82 is engaged with the linkage toothed disc 83, the linkage shaft 81 is provided with an inclination limiting movable column 84 for limiting the rotation angle of the linkage shaft 81, the turntable seat 31 is provided with an inclination limiting fixed column 85 that cooperates with the inclination limiting movable column 84 to limit the rotation angle of the linkage shaft 81, and the linkage toothed disc 83 can make all the linkage gears 82 rotate at the same inclination angle, and finally achieve the goal of making all the rotating blades 5 rotate at the same inclination angle, thereby avoiding the situation where shaking occurs due to different wind resistance caused by different angles. Figure 3 As shown, the inclination angle reset mechanism 6 includes a positioning ring body 61, a reset spring piece 62 and a reset limit seat 63. The positioning ring body 61 is fixed on the turntable seat 31, and the reset limit seat 63 is fixed on the linkage gear plate 83 around the positioning ring body 61. One end of the reset spring piece 62 is fixed on the positioning ring body 61, and the middle of the other end is pressed on the reset limit seat 63. When the fan is in the blowing mode, when the linkage gear plate 83 rotates a certain angle, the reset spring piece 62 will be compressed and deformed to store elastic force. When the fan slows down or stops working, under the action of the reset elastic force of the reset spring piece 62, the linkage gear plate 83 is reset to its initial position. The dust collector 7 is fixed to the end of the rotating cylinder 4 by threads. A filter is provided inside the dust collector 7. Air holes are provided around the dust collector 7. In the dust removal mode, the fan rotates in the opposite direction and introduces air into the dust removal filter air inlet 41 through the rotating blades 5. Finally, the air enters the dust collector 7. The air entering the dust collector 7 is discharged through the air holes. Under the action of centrifugal force, the dust is filtered by the filter.

[0022] Working process of the present invention:

[0023] In the working process of the displacement positioning fan of the present invention, in the blowing mode, the motor 1 drives the limited sliding turntable 3 to rotate, and the rotating blades 5 are driven by the limited sliding turntable 3 to rotate. Under the action of the rotating blades 5, the air is pushed downward. Since the rotating blades 5 are subjected to air resistance, the angles will be adaptively flipped. Under the action of the inclination linkage mechanism 8, all the rotating blades 5 move synchronously. The higher the speed of the fan, the greater the angle of rotation of the rotating blades 5, and vice versa. When the speed is reduced or stopped, under the action of the inclination reset mechanism 6, the angles of all the rotating blades 5 will be reduced synchronously, that is, In low-speed mode, the amount of air pushed by the surface of the rotating blades 5 is large, but the speed is low. In high-speed mode, the amount of air pushed by the surface of the rotating blades 5 is small, but the speed is fast. This can maximize the efficiency of the fan-driven air flow. At the same time, for some people who get headaches when blowing air at high wind speeds, they can choose the low wind speed mode to achieve the effect of cooling through a large amount of air flow. At the same time, the wind speed is low, and the rotating blades 5 in the dust removal mode rotate in the opposite direction. The fan pushes the air upward, and under the guiding action of the rotating blades 5, the air is introduced into the dust collector 7. Under the action of centrifugal force, the dust is confined in the dust collector 7.

[0024] The present invention provides a displacement positioning fan. By applying rotating blades 5, an inclination angle reset mechanism 6, a dust collector 7 and an inclination angle linkage mechanism 8 to the fan, the fan can have a blowing mode and a dust removal mode. In the blowing mode, the optimal cooling effect can be achieved by adaptively adjusting the inclination angle of the fan blades at different rotation speeds, which is beneficial to improving the utilization rate of electric energy. In the dust removal mode, dust in the room can be removed by centrifugal force, and the dust on the filter net can be automatically gathered to the bottom, thereby achieving the purpose of purifying the air.
