Description

Technical Field

[0001] The utility model relates to the technical field of fans, and in particular to a novel convenient mobile floor-climbing fan. Background Art

[0002] A floor fan is a fan placed on the ground and used in places that require ventilation, such as homes, factories, restaurants, and schools.

[0003] Traditional floor fans are not easy to move: Traditional floor fans are usually large and heavy, which makes them inconvenient to move. For example, during home cleaning, when you need to move the fan from one room to another, or switch between different usage scenarios (such as living rooms, bedrooms, etc.), you need to carry the fan laboriously, and it may even require two or more people to collaborate to complete the move. This causes great trouble to users and reduces the convenience and flexibility of use. Furthermore, the power cord of traditional floor fans is limited in length and is restricted by the location of the socket during movement. If you need to use the fan far away from the socket, you need to use an extension cord, which not only increases the complexity of use, but also poses safety hazards such as tripping pedestrians and electric leakage caused by damaged wires.

[0004] Traditional floor-standing fans suffer from poor ventilation and noise control: Traditional floor-standing fans often feature simple hood and blade designs, resulting in a single airflow direction, making them difficult to meet user needs for large-area ventilation in various scenarios. For example, in larger spaces (such as conference rooms and classrooms), traditional fans can only blow air in a single direction, failing to effectively cover the entire space and preventing adequate ventilation in some areas. The airflow generated by the rotating blades is unstable, prone to turbulence and high noise levels. This not only impacts the user experience, especially in environments requiring quiet, such as bedrooms and studies, but can also negatively impact physical and mental health. For example, long-term exposure to high noise levels can lead to hearing loss and irritability.

[0005] Traditional floor fans have low functional integration: Traditional floor fans are relatively simple, focusing primarily on blowing air and lacking practical additional features. For example, in places without power outlets, traditional fans are unusable, and fans without rechargeable batteries cannot meet user needs in these scenarios. Furthermore, traditional fans lack precise control over parameters such as wind speed and direction. Users can only adjust the wind speed through a limited number of gears, preventing more detailed adjustments based on actual needs.

[0006] The heat dissipation design of traditional floor fans is also not perfect: the motor generates heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will affect the performance and service life of the motor, and thus affect the overall operating stability and reliability of the fan.

[0007] The structural design and operational ease of traditional floor-standing fans need improvement: The bracket structure of traditional floor-standing fans is not well designed, and there are deficiencies in support stability and angle adjustment. For example, some bracket adjustments are complex, requiring users to use tools to adjust the angle. Alternatively, adjusting the angle can affect the fan's stability, making it prone to shaking or tipping over.

[0008] The air intake and grille designs of traditional floor-standing fans fail to adequately address both protection and heat dissipation. Their structural strength is insufficient, making them susceptible to damage from external impact, thus impacting the fan's proper function. Furthermore, the grille's poor heat dissipation can cause internal components like the motor to overheat, impacting the fan's performance and lifespan. Furthermore, the grille lacks effective noise-reduction features, effectively preventing the fan from generating noise during operation.

[0009] Furthermore, the control mechanism of traditional floor-mounted fans is typically located in a fixed position on the fan body, requiring users to bend over or reach into a specific position to operate, making it inconvenient and inefficient. Furthermore, the control mechanism may be relatively simple, providing only basic functions such as on / off and fan speed adjustment, failing to meet user needs for intelligent control (such as timer switching and remote control). Utility Model Content

[0010] In order to solve the problems raised in the above background technology, the utility model provides a new type of convenient mobile climbing fan with simple structural design, convenient movement, optimized air outlet effect and noise control, improved functional integration and high operational convenience, which brings better user experience.

[0011] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new type of convenient mobile crawling fan, comprising a fan body, wherein the fan body comprises, from front to back, an air outlet cover, a fan blade assembly, a mesh cover, an air inlet cover, a motor and a rechargeable battery, the shapes of the air outlet cover and the air inlet cover match, the mesh cover surrounds the outer periphery of the air outlet cover and the air inlet cover to form an accommodating space for the fan blade assembly, the fan blade assembly comprises a power seat and power fan blades, the power fan blades are connected to the power seat, a first mounting hole is provided in the middle of the air inlet cover, the motor is mounted at the rear end of the first mounting hole, the drive shaft of the motor extends forward and is connected to the power seat, and the rechargeable battery is arranged at the rear end of the motor and is electrically connected to the motor.

[0012] As a further elaboration of this technical solution:

[0013] Preferably, the front end of the air outlet cover is provided with a second mounting hole matching the first mounting hole, which is used to install a fan divergence block to diverge the wind blown out by the fan blade assembly to both sides to increase the blowing area. The air outlet cover and the air inlet cover both include a coiled spiral protective body and reinforcing ribs. The reinforcing ribs each include multiple ones, which are evenly distributed from the outer periphery of the first mounting hole and the second mounting hole and extend outward to the end of the protective body.

[0014] Preferably, the power seat of the fan blade assembly is three-pronged, and the power fan blades include three, which are respectively installed at the ends of the three-pronged power seat. The power fan blades include a first power blade and a second power blade. The first power blade is bird-wing-shaped and is used to push the air forward. The second power blade is connected to the rear side of the first power blade and is used to balance the force on the first power blade while enhancing the airflow stability and reducing the airflow disturbance noise. The first power blade and the second power blade are an integrated structure.

[0015] Preferably, the mesh cover is annular, and a plurality of heat dissipation holes are provided on the outer periphery of the mesh cover. The heat dissipation holes are used to optimize airflow distribution and simultaneously dissipate heat from the inner periphery of the mesh cover and reduce noise.

[0016] Preferably, a handle is provided on the upper side of the middle portion of the rear end of the air inlet cover, and the handle is welded to the air inlet cover and is used to lift and place the fan body.

[0017] Preferably, it also includes a control mechanism, and the control mechanism, motor and rechargeable battery are encapsulated together in the rear shell at the rear end of the first mounting hole. The front end of the rear shell is provided with a transmission shaft hole, and the transmission shaft of the motor is extended forward to be connected to the power seat. The rear end of the rear shell is provided with a charging hole for charging the rechargeable battery.

[0018] Preferably, it also includes a bracket assembly, which includes a supporting bracket. Reinforcement parts are provided on the left and right sides of the inner periphery of the middle part of the mesh cover. Bolts are provided on the outer side of the mesh cover corresponding to the reinforcement parts. The left and right sides of the supporting bracket are respectively connected to the left and right ends of the middle part of the mesh cover through the cooperation of hand-tightening nuts and bolts, which are used to support and stabilize the fan main body and adjust the angle of the fan main body.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] First, the utility model is easy to move as a whole. The connection design between the support bracket and the fan body makes the fan more stable and easy to operate when moving. The support bracket reduces the risk of the fan tipping over during movement. A handle is provided on the upper side of the middle of the rear end of the air inlet cover. The handle is welded to the air inlet cover and is used to lift and place the fan body, further facilitating the user's lifting and placing operations of the fan. Whether picking up the fan from the ground and placing it elsewhere, or needing to lift the fan briefly during transportation, the handle provides a convenient fulcrum. The user can easily push or lift the fan using the support bracket and handle.

[0021] Secondly, this utility model overcomes the constraints of power cords by equipping the fan with a rechargeable battery, freeing it from complete dependence on power cords. The fan can still function properly in indoor locations without power outlets, or in outdoor settings such as camping and garden parties. After charging, users can carry the fan anywhere they need it, regardless of the location of a power source, greatly expanding the fan's range of uses. For example, a user can place a charged floor fan next to the dining table to provide a comfortable breeze while dining, without having to worry about whether there is a power outlet nearby.

[0022] Thirdly, the front end of the air outlet cover of the utility model is provided with a second mounting hole for mounting a fan diverging block, which can disperse the wind blown out by the fan blade assembly to both sides, thereby increasing the blowing area. This design makes the air outlet of the fan no longer limited to a single direction, and can better cover the surrounding space. The multiple heat dissipation holes opened on the outer periphery of the annular mesh cover, on the one hand, play a role in optimizing the airflow distribution, making the blown wind more uniform; on the other hand, these heat dissipation holes contribute to the heat dissipation of the inner periphery of the mesh cover, reducing the impact of the heat generated by components such as the motor on the airflow, and at the same time can also play a role in reducing noise. Through reasonable airflow distribution and heat dissipation design, the overall performance and comfort of the fan are further improved. For example, in an environment such as an office, the fan can provide blowing services to people in multiple directions at the same time. When the fan is running, it can ensure a good ventilation effect without generating too much noise to interfere with work.

[0023] Fourthly, the power base of this utility model features a three-pronged design with three power blades. The unique combination of a first power blade (a bird-wing shape) that propels air forward and a second power blade (which balances force, enhances airflow stability, and reduces noise) effectively improves airflow stability. The first power blade efficiently propels airflow, providing sufficient air volume, while the second power blade ensures airflow stability while reducing airflow disturbances and turbulence. This not only makes the airflow softer and more comfortable, but also reduces the noise generated by unstable airflow. For example, when used in the bedroom, users can enjoy a quiet and even airflow experience without being disturbed by excessive noise.

[0024] Fifth, the utility model adopts a multifunctional control and packaging design. The control mechanism, motor and rechargeable battery are packaged together in the rear shell at the rear end of the first mounting hole, realizing the integrated management of functional components. This design not only makes the appearance of the fan more concise and beautiful, but also facilitates the unified protection and maintenance of these key components. The charging hole set at the rear end of the rear shell facilitates the charging operation of the rechargeable battery. The user can charge it directly by plugging in the battery adapter, or plugging in the solar panel power generation device for charging without disassembling other components. At the same time, the integration of the control mechanism allows the user to conveniently operate various functions of the fan, such as switch, wind speed adjustment, charging control, etc., in one location, which improves the convenience of operation and the overall user experience.

[0025] Sixth, the utility model features a rational structural design. The support bracket is connected to the middle of the mesh cover via hand-tight nuts and bolts, which not only provides stable support for the fan body but also allows for convenient angle adjustment of the fan body. Users can easily adjust the fan's blowing angle according to their needs without the need for additional tools. Both the air inlet cover and the blade cover utilize a coiled spiral protective body and evenly distributed reinforcement ribs, improving structural strength and protective performance. The protective body effectively prevents external objects from colliding with and damaging the fan's internal components, while the reinforcement ribs enhance the stability and durability of the overall structure.
