Description

Technical Field

[0001] This utility model relates to the field of fan manufacturing technology, specifically to a floor fan that is easy to adjust in angle and has good stability. Background Technology

[0002] Floor fans, as devices that deliver air close to the ground, are widely used in homes, offices, and commercial spaces due to their low center of gravity design. In existing technology, traditional floor fans typically employ a hinged support structure to adjust the airflow angle, requiring manual manipulation of the fan body to change the tilt angle.

[0003] Existing floor fans also have shortcomings in terms of heat dissipation performance and user experience. Most products use a single-layer grille heat dissipation design, which has limited heat dissipation efficiency. During continuous operation, the temperature inside the motor compartment rises significantly, affecting the lifespan of components. At the same time, the control module is mostly scattered on the side or rear of the fan body, requiring users to frequently bend over to operate it, which is not convenient to use. In terms of support structure, the base of some products lacks anti-slip treatment, which can easily cause displacement, especially when running on smooth surfaces (such as tiles), posing a safety hazard.

[0004] Therefore, how to achieve stable locking after multi-dimensional angle adjustment while ensuring structural simplicity, optimize heat dissipation path to improve equipment reliability, and integrate intelligent control to improve operational convenience has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To overcome the above problems, this utility model provides a floor fan that is easy to adjust the angle and has good stability, and can achieve a stable lock after multi-dimensional angle adjustment.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a floor fan that is easy to adjust the angle and has good stability, including a front fan body, a rear fan body, fan blades, a fan blade drive assembly and a support structure;

[0007] The support structure includes a U-shaped support frame and an adjustable stabilizing mechanism;

[0008] The adjustable stabilizing mechanism is hinged to the rear fan body and the U-shaped support frame. The rear fan body can be adjusted in angle and kept stable through the adjustable stabilizing mechanism.

[0009] The adjustable stabilizing mechanism includes a spherical joint that can drive the rear fan body to rotate around the two ends of the U-shaped support frame. The adjustable stabilizing mechanism also includes a rotating sleeve sleeved outside the U-shaped support frame. A universal telescopic component is provided between the spherical joint and the rotating sleeve.

[0010] As an improvement, the universal telescopic assembly includes a rod body connected to a ball joint, a threaded rod on a rotating sleeve, and an internal threaded sleeve rotatably connected to one end of the rod body near the threaded rod, with the internal threaded sleeve threadedly connected to the threaded rod.

[0011] As an improvement, the adjustable stabilizing mechanism further includes two connecting discs located between the two ends of the rear fan body and the U-shaped support frame. The two connecting discs are symmetrically distributed, fixedly connected to the rear fan body, and rotatably connected to the two ends of the U-shaped support frame.

[0012] As an improvement, a U-shaped rod is provided between the two connecting discs, and an extension rod is provided between the U-shaped rods. The end of the extension rod away from the U-shaped rod is fixedly connected to the ball joint.

[0013] As an improvement, radial heat dissipation grilles are provided on the front and rear fan bodies to form a double-layer ventilation structure, and the gap width of the radial heat dissipation grilles is 3-8mm.

[0014] As an improvement, the top of the rear fan body is provided with an integrated control module, which includes operation buttons and sensors for adjusting wind speed and angle.

[0015] The U-shaped support frame is provided with anti-slip texture.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. Unified Multi-Dimensional Angle Adjustment and Stable Locking: Through the synergistic effect of the ball joint and universal telescopic components, the limitations of traditional single-axis hinges are overcome, enabling multi-dimensional angle adjustment of pitch and yaw. The threaded pair mechanism composed of the threaded rod and the internal threaded sleeve can achieve mechanical self-locking by tightening after angle adjustment. Combined with the rigid structure of the U-shaped support frame, it ensures that the fan body has no rebound or wobbling at any angle from 0-90°, solving the technical problem of easy loosening after the angle of the traditional structure is fixed.

[0018] 2. Anti-slip composite stabilizing structure: The anti-slip texture at the bottom of the U-shaped support frame forms an anti-slip system with a static friction coefficient of 1.2-1.5. Combined with the triangular force-bearing structure of the adjustable stabilizing mechanism, the whole machine can withstand aerodynamic loads at a wind speed of 5m / s on the tile floor without displacement, and the safety meets the standards of industrial equipment.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figures 1 to 4 The floor fan body consists of a front fan body 1 and a rear fan body 2 forming a shell assembly, which are connected by snap-fit ​​to form a hollow cavity. A fan blade drive assembly 4 is provided at the joint between the front fan body 1 and the rear fan body 2. This assembly includes a brushless motor and a drive shaft. The drive shaft passes through the rear fan body 2 and is fixedly connected to the fan blades 3. The fan blades 3 adopt a five-blade streamlined design and are installed on the air inlet side of the front fan body 1.

[0026] The support structure consists of a U-shaped support frame 5 and an adjustable stabilizing mechanism 6. The U-shaped support frame 5 is formed by bending 304 stainless steel tubing with a diameter of 12mm. Its bottom horizontal section has anti-slip texture, and a silicone pad is attached to the surface in contact with the ground. The two connecting discs 602 of the adjustable stabilizing mechanism 6 are symmetrically fixed to the two side walls of the rear fan body 2 by bolts. The center of the connecting disc 602 has a bearing with a diameter of 8mm, forming a rotating pair with the rotating shafts at the two vertical ends of the U-shaped support frame 5.

[0027] The U-shaped rod 601 is laterally connected to two connecting discs 602, and its open end is connected to the extension rod 603 via threaded fasteners. A ball joint 604 is welded to the end of the extension rod 603, which forms a universal joint with the rotating sleeve 605 fitted onto the U-shaped support frame 5. An M8 threaded rod 606 is welded to the outside of the rotating sleeve 605. The front end of the rod body 607 is connected to the ball joint 604 via a ball joint, and the end is fitted with an internally threaded sleeve 608. The effective length of the rod body 607 can be changed by rotating the internally threaded sleeve 608.

[0028] The front fan body 1 and the rear fan body 2 are provided with radial heat dissipation grilles on their housing surfaces. The grille gap width of the front fan body 1 is 3mm, and the grille gap width of the rear fan body 2 is 8mm, forming a progressive heat dissipation channel. An integrated control module is embedded in the top of the rear fan body 2. This module includes touch operation buttons, a gyroscope sensor, and a wireless communication chip, and is connected to the frequency converter controller of the fan blade drive assembly 4 via a CAN bus.

[0029] In practical implementation, when the air delivery angle needs to be adjusted, the user rotates the inner threaded sleeve 608 to cause the rod 607 to move axially, driving the ball joint 604 to move the rear fan body 2 in a pitching motion around the rotation axis of the U-shaped support frame 5. After adjustment, the inner threaded sleeve 608 is tightened to lock the angle. The anti-slip texture at the bottom of the U-shaped support frame 5 generates static friction with the ground, which, together with the multi-point support structure of the adjustable stabilizing mechanism 6, ensures that the fan body can work stably at any angle within the range of 0-90°.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
