Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a floor fan. Background Technology

[0002] A floor fan is a common air conditioning appliance, mainly composed of a motor, fan blades, fan head, column, and base. It uses a motor to drive the fan blades to rotate, creating airflow to achieve ventilation, cooling, and air exchange. When the motor is connected to a power source, the coil inside the motor generates a magnetic field, causing the rotor to rotate. The rotor, through a shaft, drives the fan blades. As the blades rotate, they propel air forward, creating a breeze. Different floor fans may have different wind speed settings and oscillation functions. Wind speed is adjusted by changing the motor speed, and the oscillation mechanism causes the fan head to swing left and right, expanding the airflow range. The telescopic design of the column allows the height of the fan head to be adjusted according to the user's height and usage scenario for optimal airflow.

[0003] However, existing floor fans have the following problems when in use:

[0004] Currently, most floor fans on the market are not equipped with casters and are usually carried by hand, which is extremely inconvenient and strenuous. In terms of height adjustment, the traditional column adjustment method usually involves pulling it upwards by hand, which is not very stable and is prone to shaking or jamming, affecting the user experience and lifespan.

[0005] This invention enables flexible movement and stable fixation of the floor fan through structures such as casters and suction cups; the suction cup lifting is precisely controlled by gear and toothed plate transmission, and the height adjustment is ensured to be smooth and stable by guide rods, fixing rods and sliders, effectively improving the convenience, stability and safety of use. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a floor fan.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a floor fan, comprising: a base, a control column fixedly installed on the upper end of the base, a fan head slidably connected to the upper end of the control column, a partition fixedly installed inside the control column, casters fixedly installed at the four corners of the bottom of the base, a slot opened at the upper end of the control column, sliding grooves opened at both ends of the slot, a fixed cover fixedly installed at the bottom of the fan head, the fixed cover being adapted to the size of the upper end of the control column, a fixed rod fixedly installed at the bottom of the fixed cover, the fixed rod being slidably connected to the slot, an internally threaded sleeve provided inside the fixed rod, and sliders fixedly installed at the bottom of the left and right ends of the fixed rod, the sliders being slidably connected to the sliding grooves.

[0008] A further preferred embodiment: a movable rod is slidably mounted behind the universal wheel, a suction cup is fixedly mounted at the bottom of the movable rod, and a handle is rotatably connected to the right end of the universal wheel.

[0009] A further preferred embodiment: a gear is fixedly installed on the left end of the handle, and a toothed plate is fixedly installed on the front of the moving rod. The toothed plate has a toothed groove on its front side, which meshes with the gear.

[0010] A further preferred embodiment: the control column has several heat dissipation vents on its back, a light strip groove on its front, a control panel fixedly mounted on its front, and the light strip groove surrounding the control panel.

[0011] A further preferred embodiment: guide holes are provided on both the left and right sides of the slot, and the guide holes are slidably connected to the fan head.

[0012] A further preferred embodiment: guide rods are fixedly installed on the left and right sides below the fan head, the guide rods are fixedly installed on the left and right sides of the bottom of the fixed cover, and the guide rods are slidably connected by being embedded in the guide holes.

[0013] A further preferred embodiment: a motor is fixedly installed at the upper end of the partition, and a screw is fixedly installed at the output end of the motor, the screw being threadedly connected to an internally threaded sleeve.

[0014] Beneficial effects:

[0015] 1. Equipped with casters and suction cups, the casters allow the floor fan to move easily between different spaces and complex terrains. Whether in the living room, bedroom, or uneven outdoor ground, users can effortlessly push it to the desired location, eliminating the hassle of moving traditional floor fans. The suction cups solve the problem of fixing the floor fan. After reaching the destination, a simple operation allows the suction cups to adhere tightly to the ground, firmly fixing the body and preventing displacement or tipping caused by vibration from the fan's operation or accidental collisions. This provides users with a safe and reliable user experience. This design not only meets the need for convenient movement in daily use but also maintains stability during use, achieving "move when you want, stay still when you want," greatly improving the convenience and safety of floor fan use and adapting to diverse usage scenarios.

[0016] 2. Through a transmission structure with gears and toothed plates meshing together, the circular motion of the user turning the handle is efficiently converted into the linear motion of the moving rod, making operation more effortless and precise. When the floor fan needs to be fixed, the user only needs to turn the handle gently, and the gears drive the toothed plates to precisely control the moving rod to slide down, so that the suction cup can be smoothly attached to the ground and generate a firm suction force. When the handle is turned in the opposite direction, the tight cooperation between the gears and toothed plates allows the moving rod to rise at a uniform speed, so that the suction cup can be smoothly lifted off the ground. This structure not only reduces the difficulty of operation, but also ensures the stability and reliability of the movement process, avoiding problems such as uneven force and jamming caused by manually pushing and pulling the moving rod. The ingenious mechanical design improves the practicality and durability of the floor fan's fixing and moving functions.

[0017] 3. The system is equipped with a guide rod, a fixed rod, and a slider. The fixed rod, as the core component connecting the fan head and the control column, works with the internal screw to achieve height changes. The slider at its bottom is embedded in the control column's groove, serving as a guide and limiter during height adjustment, preventing the fixed rod from shifting or wobbling during movement and ensuring a smooth and stable adjustment process. At the same time, the guide rod below the fan head is embedded in the control column's guide hole, forming a double guide structure with the slider, further enhancing the stability of the fan head during lifting and lowering. This makes the entire height adjustment process as precise and controllable as sliding on a track. The three components work together to not only improve the accuracy and smoothness of height adjustment but also enhance the robustness of the connection between the fan head and the control column, effectively reducing noise and safety hazards caused by loose components, and providing users with a more reliable and comfortable user experience.

[0018] 4. In summary, this type of floor fan, through the design of casters, suction cups, gears, toothed plates, guide rods, fixing rods, and sliders, allows the floor fan to move freely and be securely fixed in different scenarios. The transmission design of the gears and toothed plates controls the lifting and lowering of the suction cups in a labor-saving and precise manner, making the fixing process easier and more reliable. The guiding system composed of guide rods, fixing rods, and sliders ensures that the fan head moves smoothly and steadily during height adjustment, avoiding wobbling and deviation, and accurately meeting the user's needs for airflow height. These structures work together to not only improve the practicality and durability of the floor fan, but also optimize the user experience from the details, bringing a more efficient and comfortable experience to daily life.

Detailed Implementation

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-5In this embodiment of the utility model, a floor fan includes: a base 1, a control column 2 fixedly installed on the upper end of the base 1, a fan head 3 slidably connected to the upper end of the control column 2, a partition 4 fixedly installed inside the control column 2, casters 101 fixedly installed at the four corners of the bottom of the base 1, a slot 204 opened at the upper end of the control column 2, and sliding grooves 205 opened at both the left and right ends of the slot 204, a fixing cover 301 fixedly installed at the bottom of the fan head 3, the fixing cover 301 being adapted to the size of the upper end of the control column 2, a fixing rod 303 fixedly installed at the bottom of the fixing cover 301, the fixing rod 303 being slidably connected inside the slot 204, an internally threaded sleeve being provided inside the fixing rod 303, and sliders 304 fixedly installed at the bottom of the left and right ends of the fixing rod 303. 04 is slidably connected to the slide groove 205. Several heat dissipation vents 201 are opened on the back of the control column 2. Guide holes 206 are opened on both the left and right sides of the slot 204. The guide holes 206 are slidably connected to the fan head 3. Guide rods 302 are fixedly installed on the left and right sides below the fan head 3. The guide rods 302 are fixedly installed on the left and right sides of the bottom of the fixed cover 301. The guide rods 302 are slidably connected to the guide holes 206. The upper end of the partition 4 is fixedly installed with a motor 401. The output end of the motor 401 is fixedly installed with a screw 402. The screw 402 is threadedly connected to the internal threaded sleeve. Since universal wheels 101 are fixedly installed at the four corners of the bottom of the base 1, the base can be easily pushed when the floor fan needs to be moved. The rotation of the universal wheels 101 allows the floor fan to move flexibly on the ground. Move the fan head 3 to the desired position. When the height of the fan head 3 needs adjustment, start the motor 401 at the upper end of the internal partition 4 of the control column 2. The motor 401 operates, and its output end drives the screw 402 to rotate. Because the screw 402 is threadedly connected to the internal threaded sleeve inside the fixed rod 303, as the screw 402 rotates, the internal threaded sleeve moves up and down on the screw 402. The movement of the internal threaded sleeve drives the fixed rod 303 to move. The sliders 304 at the bottom of the left and right ends of the fixed rod 303 are slidably connected to the sliding grooves 205 at the left and right ends inside the slot 204 on the control column 2. This ensures the stability and guidance of the fixed rod 303 when it moves up and down. At the same time, the guide rods 302 fixedly installed on the left and right sides below the fan head 3 are embedded in the slot 204 on the control column 2. The guide holes 206 on both sides slide internally, further assisting the vertical movement of the fan head 3, allowing it to rise or fall smoothly in the vertical direction, thus achieving height adjustment. During the operation of the floor fan, components such as the motor 401 generate heat. Several heat dissipation vents 201 on the back of the control column 2 help air circulation, dissipating the internal heat, ensuring the normal operating temperature of the motor and other components, and extending their service life. The fan head 3 is connected to the control column 2 via a fixing cover 301 at the bottom. The fixing cover 301 is adapted to the size of the upper end of the control column 2, allowing the fan head 3 to be stably placed on the control column 2. The fixing rod 303 is inserted into the slot 204 for sliding connection. This structure not only realizes the height adjustment function, but also...It also serves to position and secure the fan head 3 during installation, ensuring a stable connection between the fan head 3 and the control column 2, preventing it from easily shaking or falling off during operation.

[0027] In this embodiment of the invention, a movable rod 102 is slidably mounted behind the universal wheel 101. A suction cup 103 is fixedly mounted at the bottom of the movable rod 102. A handle 104 is rotatably connected to the right end of the universal wheel 101. A gear 105 is fixedly mounted to the left end of the handle 104. A toothed plate 106 is fixedly mounted on the front of the movable rod 102. The toothed plate 106 has a toothed groove on its front and meshes with the gear 105. When the floor fan is moved to the desired position, it needs to be fixed to prevent it from moving arbitrarily. At this time, rotating the handle 104 rotatably connected to the right end of the universal wheel 101 causes the gear 105, which is fixedly mounted on the left end of the handle 104 and meshes with the toothed plate 106 fixedly mounted on the front of the movable rod 102, to rotate the handle 104. The rotation of the gear 105 drives the toothed plate 106 to move. Because the toothed plate 106 is fixedly installed on the moving rod 102, the moving rod 102 will slide behind the caster 101 together with the toothed plate 106. The bottom of the moving rod 102 is fixedly installed with a suction cup 103. When the moving rod 102 slides down, the suction cup 103 will gradually approach the ground. Continue to rotate the handle 104 to make the suction cup 103 make close contact with the ground and generate suction force, thereby firmly fixing the floor fan to the ground and preventing it from moving due to accidental collision or other reasons during use. When it is necessary to move the floor fan again, rotate the handle 104 in the opposite direction. Similarly, through the meshing transmission of the gear 105 and the toothed plate 106, the moving rod 102 slides up. As the moving rod 102 rises, the suction cup 103 separates from the ground, the suction force disappears, and the floor fan can then be moved flexibly by the caster 101.

[0028] In this embodiment of the utility model, a light strip groove 202 is provided on the front of the control column 2, and a control panel 203 is fixedly installed on the front of the control column 2. The light strip groove 202 is opened around the control panel 203, and a light strip is embedded in the light strip groove 202. The light strip can emit a weak light to illuminate the control panel 203, making the various control buttons on the control panel 203 clearer. The control panel 203 has buttons for controlling the wind speed and gear, and has several ports, including USB ports and round hole ports. These ports are all connected to the fan through the circuit on the back of the control panel 203.

[0029] Working principle: When the floor fan needs to be moved, the user can directly push the base 1. Since the base 1 has four casters 101 at its bottom corners, it can rotate 360 ​​degrees flexibly, easily moving the floor fan to the desired position. Once in the designated position, the user rotates the handle 104 connected to the right end of the casters 101. The gear 105 at the left end of the handle 104 rotates accordingly. The gear 105 meshes with the toothed plate 106 on the front of the moving rod 102, causing the moving rod 102 to slide down behind the casters 101. This causes the suction cup 103 at the bottom of the moving rod 102 to make close contact with the ground and generate suction force, allowing the fan to move from the ground. To securely fix the floor fan, if it needs to be moved again, simply turn the handle 104 in the opposite direction. The moving rod 102 will rise, and the suction cup 103 will detach from the ground, allowing the floor fan to be moved again. Users can activate the motor 401 at the upper end of the internal partition 4 of the control column 2 via the control panel 203. The output of the motor 401 drives the screw 402 to rotate. The screw 402 is threadedly connected to the internal threaded sleeve inside the fixing rod 303. As the screw 402 rotates, the internal threaded sleeve moves up and down on the screw 402, thereby moving the fixing rod 303. The sliding joints at the bottom of the left and right ends of the fixing rod 303... Block 304 slides in the groove 205 inside slot 204, providing stable guidance; simultaneously, the guide rod 302 below the fan head 3 slides in the guide hole 206, assisting the fan head 3 to smoothly rise or fall vertically, achieving precise height adjustment. The user presses the switch button on the control panel 203 to start the fan head 3. The fan speed can be adjusted using the wind speed and gear control buttons to meet different airflow needs. During operation, the heat generated by components such as the motor 401 is dissipated through the heat dissipation vent 201 on the back of the control column 2, ensuring... The motor and other components are kept at normal operating temperature to extend their service life. The LED strip in the LED strip slot 202 turns on by default after the floor fan is powered on, emitting a faint light to illuminate the control panel 203, making it easier for users to see the control buttons. Users can also adjust the LED strip's on / off state, brightness, and color through the light control buttons on the control panel 203. In addition, the USB port and round hole port on the control panel 203 can connect to external devices (such as mobile phone charging, connecting smart devices to control the fan, etc.). These ports are connected to the fan through the circuitry on the back of the control panel 203 to realize data transmission or power supply functions.
