Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a tower fan. Background Technology

[0002] Tower fans are popular in the market due to their small footprint and simple, aesthetically pleasing design. They typically feature a tall, slender body and a narrow air outlet. To improve airflow range, existing tower fans generally incorporate an automatic left-right oscillation function to deliver air to a wider area.

[0003] However, in actual use, this fixed automatic oscillation mode, with its preset and fixed oscillation angle and rhythm, cannot meet the personalized needs of users who wish to direct airflow to specific locations (such as sofas or beds) as their airflow changes frequently. When users want a fixed airflow direction, they must approach the tower fan and manually press the stop oscillation button, which is inconvenient. Furthermore, even when the oscillation stops, due to the narrow air outlet of the tower fan, it is difficult to accurately align the initial stop position with the user, usually requiring the user to manually fine-tune the angle of the unit, resulting in a still unsatisfactory experience.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] like Figures 1 to 5 As shown, a tower fan includes a base assembly, a rotating assembly, and a body assembly. The rotating assembly is disposed on the base assembly. The rotating assembly includes a drive motor and a transmission mechanism, and the output shaft of the drive motor is driven and transmitted to the drive motor. The body assembly is rotatably connected to the rotating assembly and is spaced apart from the base assembly. The body assembly has a receiving cavity and an air inlet and an air outlet communicating with the receiving cavity. The drive motor drives the body assembly to rotate relative to the base assembly through the transmission mechanism to adjust the orientation of the air outlet.

[0044] In this embodiment, the drive motor is a stepper motor; wherein, the stepper motor divides a full rotation into several equal small steps. When the main control MCU sends a pulse signal to the stepper motor driver, the motor shaft will rotate one step precisely. In this way, the main control MCU can precisely control the angle of rotation of the machine body by sending a specific number of pulses, thereby realizing the fine-tuning function of rotating by a preset angle with each button press.

[0045] In this embodiment, a control module and a remote controller are also included; the remote controller is equipped with a button for sending steering control signals; the control module is located on the tower fan and is used to receive signals sent by the remote controller and control the start, stop and steering of the drive motor according to the signals.

[0046] In this embodiment, the remote control is equipped with a left turn button and a right turn button; the control signal includes a left turn command and a right turn command; wherein, the control module is configured to: upon receiving a left turn command or a right turn command, control the drive motor to drive the transmission mechanism to rotate the body assembly by a preset angle, specifically: when the left turn command is received, control the drive motor to drive the transmission mechanism to rotate the body assembly to the left; when the right turn command is received, control the drive motor to drive the transmission mechanism to rotate the body assembly to the right.

[0047] When a user senses an incorrect wind direction, they don't need to get up. Simply press the corresponding directional control button on the remote control, such as the left or right turn button. Once the control module inside the tower fan receives the directional control signal from the remote control, its main chip (MCU) immediately decodes the signal. Based on the decoded instruction, such as the left turn instruction, the chip calls a preset program and sends electrical signals to the drive motor to start and turn left. After receiving the current and left turn instruction from the control module, the drive motor (i.e., the stepper motor) begins to rotate. The rotation direction and speed of its output shaft are precisely controlled by the control module. At the same time, the transmission mechanism is driven to rotate by the stepper motor, converting the high-speed, low-torque rotation of the motor into low-speed, high-torque rotation. The output end of the transmission mechanism is fixedly connected to the body assembly, so that the motor has enough power to smoothly drive the heavy body assembly to rotate. That is, when the transmission mechanism rotates slowly and powerfully, it will directly drive the entire body assembly to rotate relative to the stationary base assembly, thereby changing the orientation of the narrow air outlet on the body assembly. In other words, the user controls the drive motor to rotate via remote control, which in turn drives the transmission mechanism to rotate the main body components by a preset angle. This effectively adjusts the direction of the air outlet, allowing it to adjust with the user's position and significantly improving the user experience. Because the main body rotates as a whole, all areas of the air outlet change direction simultaneously, achieving the ultimate effect of maximizing the airflow towards the user.

[0048] In other words, when the user briefly presses the left or right turn button, the remote control sends a corresponding command signal. The tower fan's control module receives and processes this command. Each time the main control MCU receives a valid command, it sends a fine-tuning command to the stepper motor's drive circuit. The stepper motor receives and executes this fine-tuning action, rotating by a fixed step angle. This rotation is then transmitted through the transmission mechanism to the body assembly. Thus, each time a button is pressed, the entire body assembly smoothly rotates by a preset angle to align the center point of the air outlet with the user, allowing the user to clearly perceive the change in airflow direction. Ultimately, this achieves the convenient effect of "precisely adjusting the airflow without moving the machine."

[0049] In this embodiment, the transmission mechanism includes a first gear and a second gear that mesh with each other. The output shaft of the drive motor is connected to the first gear, and the second gear is fixedly connected to the body assembly. The drive motor 27 is a stepper motor, which serves as the drive source. Its output shaft directly drives the first gear 24 to rotate. The first gear 24 meshes with a second gear 22, which has a larger diameter, causing the second gear 22 to rotate. The second gear 22 is rigidly connected to the body assembly via a shaft. When the gear rotates, it directly drives the body assembly to rotate. The internal cavity of the body assembly contains a fan system. Air is drawn in through the air inlet, accelerated by the blower assembly, and then discharged through the air outlet.

[0050] In other words, the gear transmission uses a reduction ratio design, converting the high-speed motor output into low-speed, high-torque motion. This avoids excessively rapid turning that could cause vibration, ensuring smooth rotation of the body components. This improves upon the shortcomings of traditional structures, such as motion dead spots, frequent start-stop and reversal noises, unstable rotation, and high mechanical noise. Furthermore, because the body components and base component 1 are spaced apart, the internal air duct structure of the body components remains undisturbed when the rotating component adjusts its direction, ensuring continuous airflow output during turning. The rotational force of the gears overcomes friction, allowing the body components to freely turn, thus enabling fine-tuning of the air outlet to the left or right, ensuring the entire tower fan's air outlet faces the consumer directly. In addition, the base component 1 provides a wide support surface, lowering the center of gravity to counteract the swaying of the body components during rotation.

[0051] Upon startup, the drive motor 27 receives a signal and drives the first gear 24, which in turn drives the second gear 22 to rotate, achieving speed reduction through gear ratio. The second gear 22 drives the body assembly to rotate, causing the airflow direction at the outlet to change periodically. This gear transmission controls the rotation of the body assembly, significantly reducing noise compared to linkage mechanisms. Furthermore, if directional airflow is required, the drive motor 27 stops upon receiving a control signal, maintaining the angle of the body assembly through gear self-locking to achieve directional airflow. Thus, this tower fan achieves automatic outlet rotation through the mechanical linkage of the base assembly 1, the rotating assembly, and the body assembly. The motor-driven gear transmission enables smooth rotation of the body assembly, effectively adjusting the outlet direction and expanding the airflow range, thus solving to some extent the problems of limited airflow space and the need for manual movement in existing tower fans.

[0052] In this embodiment, as Figure 1As shown, the rotating assembly further includes a fixing member 21, a rotating shaft 23, and a support member 26; the fixing member 21 is disposed on the base assembly 1, and the fixing member 21 has a shaft hole; the rotating shaft 23 is inserted into the shaft hole through a bearing; the support member 26 is sleeved on the fixing member 21 and forms a space between the support member 26 and the fixing member 21; wherein, the drive motor 27 and the first gear 24 are both disposed on the support member 26; the second gear 22 is sleeved on the rotating shaft 23 and is located in the space; one end of the rotating shaft 23 is rotatably connected to the body assembly to drive the body assembly to rotate.

[0053] The structure of the rotating component is further refined, achieving more stable rotation of the fuselage assembly through the precise cooperation of the fixing member 21, the rotating shaft 23, and the support member 26. Specifically: the fixing member 21 is installed and fixed on the base assembly 1, serving as the static reference for the entire rotating system. Its shaft hole is embedded with a bearing (usually a ball bearing) to reduce the frictional resistance when the rotating shaft 23 rotates. The rotating shaft 23 passes through the shaft hole of the fixing member 21, achieving low-resistance rotation through the bearing. Its upper end is connected to the fuselage assembly, bearing the weight of the fuselage and wind pressure. Its lower end is fitted with the second gear 22 to transmit rotational torque. The support member 26 is fitted outside the fixing member 21, forming an annular space with the fixing member 21. It serves as a mounting platform for the drive motor 27 and the first gear 24, isolating the power components from the base and reducing vibration transmission. Preferably, the drive motor 27 can be a stepper motor or a DC geared motor, fixed on the support member 26. Its output shaft directly drives the first gear 24 (i.e., the driving gear). Preferably, the first gear 24 is usually a small module gear with fewer teeth to achieve high-speed output. The first gear 24 meshes with the second gear 22 (i.e., the driven gear), and the torque is amplified through gear reduction. The second gear 22 transmits the amplified torque to the rotating shaft 23. The top of the rotating shaft 23 is locked to the machine body assembly through a flange coupling or pin, driving the machine body to rotate at a low speed. Compared with traditional linkage mechanisms and simple direct motor connection, gear transmission converts the high-speed motor output into low-speed, high-torque motion, avoiding excessively fast steering and vibration, ensuring smooth rotation of the machine body assembly, thereby improving the defects of traditional structures such as motion dead points, frequent start-stop reversal noise, unstable rotation, and high mechanical noise. It can be seen that the support member 26 can prevent motor vibration from being transmitted to the base assembly 1 through the fixing member 21, reducing noise. A certain gap is maintained between the second gear 22 and the support member 26 to prevent thermal expansion from causing jamming.

[0054] In this embodiment, the fuselage assembly includes a tower fan body and a rotating base disposed at the bottom of the tower fan body. The rotating base is connected to the transmission mechanism to achieve rotation. Wherein, as... Figure 1As shown, the tower fan body includes a front shell assembly 61, a rear shell assembly 62, a blower assembly 5, and a second motor 4; the front shell assembly 61 is provided with the air outlet; the rear shell assembly 62 is provided with the air inlet; the rear shell assembly 62 and the front shell assembly 61 are detachably connected to the rear shell assembly 62 and enclose to form the receiving cavity; the blower assembly 5 is disposed in the receiving cavity; the second motor 4 is coaxially connected to the blower assembly 5 and is used to drive the blower assembly 5 to rotate.

[0055] In this embodiment, the design of the body components is further refined. Through the modular cooperation of the front shell assembly 61, rear shell assembly 62, blower assembly 5, and second motor 4, efficient air delivery and convenient maintenance are achieved. Specifically: the front shell assembly 61 forms the front of the body and is equipped with an air outlet. Preferably, the air outlet is typically a vertical grid or mesh structure, balancing airflow output and safety protection to prevent fingers from entering. The rear shell assembly 62 forms the back of the body and is equipped with an air inlet. Preferably, the air inlet is a bottom or back strip-shaped hole to ensure unobstructed airflow. The front shell assembly 61 and rear shell assembly 62 are double-fixed by clips and screws, enabling quick assembly and disassembly. Furthermore, after the second motor 4 is started, the blower assembly 5 rotates at high speed, creating negative pressure within the receiving cavity. External air is drawn in through the air inlet, accelerated along the tangential direction of the blower assembly 5 blades, and centrifugal force throws the air towards the outer edge of the impeller, then flows to the air outlet of the front shell assembly 61.

[0056] Preferred, such as Figure 1 As shown, the front shell assembly 61 includes a front shell bracket and a front shell portion 613. The front shell portion 613 is detachably disposed at an opening 612 on the side of the front shell bracket opposite to the rear shell assembly 62, meaning the front shell portion 613 can be magnetically or snapped to the front shell bracket. The front shell bracket also has a receiving seat 611, which is located within a receiving cavity and is used to house the blower assembly 5 and separate the blower assembly 5 from the second motor 4. In other words, the front shell bracket and the rear shell assembly 62 divide the receiving cavity into an upper receiving cavity and a lower receiving cavity through the receiving seat 611. The blower assembly 5 is located in the upper receiving cavity, with no moving parts interfering with airflow, reducing turbulence noise. Preferably, a rubber damping layer can also be placed inside the receiving seat 611 to block the transmission of motor vibration to the blower assembly 5. The second motor 4 and the rotating component are both located in the lower receiving cavity. Heat is discharged through the ventilation holes of the base assembly 1, preventing hot air from rising and affecting the blower efficiency, achieving more efficient heat dissipation and isolation, modular maintenance, and improved space utilization.

[0057] In this embodiment, as Figures 3 to 5As shown, the rear shell assembly 62 has a mounting groove on the side wall facing the receiving cavity, and a fixing cover 25 is provided in the mounting groove. Preferably, the bottom of the mounting groove has a threaded post or a snap-fit ​​position for fixing the fixing cover 25, and the groove is surrounded by reinforcing ribs to ensure the stability of the load-bearing components. That is, in this embodiment, the rear shell assembly 62 further optimizes the installation stability and maintenance convenience of the internal components by adding a mounting groove and a fixing cover 25. Figures 3 to 5 As shown, the fixing cover 25 is sleeved on the rotating shaft 23 to rotatably connect the body assembly to the rotating shaft 23. In this embodiment, the rotating shaft 23 serves as a core transmission component, with its upper end connected to the inside of the body assembly via the fixing cover 25, and its lower end connected to the base assembly 1 via a bearing. Preferably, the fixing cover 25 is a ring-shaped kit made of metal or high-strength plastic, with a flange edge on its outer edge. This flange edge mates with the mounting groove to achieve a fixed connection between the body assembly and the rotating assembly. Preferably, a silicone gasket can be added to the contact surface between the flange edge and the mounting groove to suppress resonance noise. The top of the rotating shaft 23 is machined with a flat end or keyway, which meshes with the corresponding structure of the inner hole of the fixing cover 25 to ensure torque transmission without slippage, while also limiting the vertical movement of the body assembly. In other words, the stable rotational connection of the body assembly is achieved through the cooperative design of the fixing cover 25 and the rotating shaft 23, while simplifying the assembly process.

[0058] In this embodiment, the rear housing assembly 62 has a limiting groove on its side wall facing the receiving cavity, and the limiting groove has a support assembly 3 for supporting the second motor 4. In this embodiment, the limiting groove is located on the inner side wall of the rear housing assembly 62 facing the receiving cavity, usually near the bottom (i.e., the lower receiving cavity), corresponding to the installation position of the second motor 4. The output shaft of the second motor 4 is aligned with the coupling of the blower assembly 5 and pushed into place to complete the installation of the second motor 4 on the support assembly 3, ensuring the coaxiality of the second motor 4 and the blower assembly 5, reducing vibration and noise, and limiting the axial / radial displacement of the second motor 4 during operation to prevent loosening of the connection due to vibration. In addition, the support assembly 3 has a shock-absorbing pad made of silicone or rubber to reduce the transmission of vibration of the second motor 4 to the housing assembly. That is, the limiting groove is designed on the inner side wall of the rear housing assembly 62, and the second motor 4 is fixed and supported by the support assembly 3 to ensure its stable operation, while facilitating assembly and maintenance.

[0059] In this embodiment, as Figure 5 As shown, the support assembly 3 has multiple mounting posts 31 on the side facing the fixed cover 25; the fixed cover 25 has multiple protrusions 251 correspondingly; wherein, the protrusions 251 and the mounting posts 31 are fitted together to achieve the positioning connection between the support assembly 3 and the fixed cover 25. The support assembly 3 and the fixed cover 25 achieve high-precision positioning and stable connection through the fitting structure of the protrusions 251 and the mounting posts 31, ensuring the long-term stable operation of the second motor 4 and the rotating assembly.

[0060] In this embodiment, as Figure 1 As shown, the front shell assembly 61 is also provided with a placement slot 614 for placing the remote control, so as to enable users to conveniently access it.

[0061] In this embodiment, as Figure 1 As shown, it also includes an emergency stop component 7, which is disposed in the receiving cavity and located at the end of the blower assembly 5 opposite to the second motor 4. The emergency stop component 7 is added to the end of the blower assembly 5 to achieve rapid braking in emergency situations and ensure user safety.
