Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fan technology, and more specifically, it relates to a desktop tower fan. Background Technology
[0002] Existing desktop tower fans typically employ a vertical cylindrical casing structure with a single built-in cross-flow fan. Their working principle is as follows: air is drawn in through an inlet located at the bottom or rear of the casing, accelerated by the cross-flow fan, and then expelled through a narrow, vertical outlet on the front of the casing, creating a relatively wide airflow. These products, with their compact design (saving space), relatively low operating noise, and multi-speed fan adjustment capabilities, can provide effective localized ventilation and cooling for individuals or small areas.
[0003] However, due to their inherent single-flow fan structure and single vertical air outlet design, existing desktop tower fans have a significant drawback: their airflow direction is strictly limited to a single direction on the front of the unit. When a user places such a tower fan on a desktop, the airflow it generates can only cover a fan-shaped area in front of it. This prevents it from simultaneously delivering airflow in multiple different directions, making it difficult to meet the needs of multiple users (e.g., two people) in the same desktop environment to receive effective airflow at the same time. Therefore, in view of this, this paper studies and improves the existing structure and its shortcomings to provide a desktop tower fan with greater practical value. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a desktop tower fan, which is achieved by the following specific technical means: A desktop tower fan includes a base, a fixed frame rotatably connected to the top of the base, and two sets of fans installed inside the fixed frame; each fan is rotatably connected to a rotating seat on its outer side, and the two sets of fans are rotatably mounted at the upper and lower ends of the fixed frame respectively via the rotating seats; each fan has a mounting groove at the center of the front fan frame, and an infinity mirror light assembly is installed inside the mounting groove.
[0005] Furthermore, a pair of connecting seats are connected to one side of the rotating seat by fasteners, and a fixed shaft is provided on the opposite side of each pair of connecting seats; a connecting strip is provided on the outer side of the fan, and both ends of the connecting strip are provided with fixing holes for insertion into the fixed shaft, and the fixing holes and the fixed shaft are interference fit.
[0006] Furthermore, the fixed frame is composed of a rear frame and a front frame spliced together; both the upper and lower ends of the rear frame and the front frame are provided with arc-shaped grooves; the rotating seat is circular and is fitted and installed in the arc-shaped groove between the rear frame and the front frame.
[0007] Furthermore, the base is composed of a bottom shell and a top cover; the top of the top cover is provided with a rotating groove, and a turntable is rotatably installed inside the rotating groove; the bottom ends of the rear frame and the front frame are both provided with base plates connected to the turntable, and the base plates are fastened to the turntable by fastening screws.
[0008] Furthermore, a through hole is provided in the center of the rotating groove, and a connecting shaft that mates with the through hole is provided at the bottom center of the turntable. The bottom end of the connecting shaft passes through the through hole and a limiting plate is fixedly installed on the bottom side of the upper cover. A drive motor is fixedly installed inside the bottom shell, and the output shaft of the drive motor is fixedly connected to the center of the limiting plate.
[0009] Furthermore, a motherboard and a battery are also installed inside the bottom shell; the motherboard is electrically connected to the fan, drive motor and battery; a control component and a display component are installed on the motherboard; the control component is a set of touch buttons and the display component is a display screen.
[0010] Furthermore, the infinity mirror lighting assembly includes a reflector, a light strip, and coated glass; the reflector is fixedly installed at the bottom of the mounting groove, the coated glass is fixedly installed at the opening of the mounting groove, and the light strip is fixedly installed on the inner peripheral wall of the mounting groove and located between the reflector and the coated glass.
[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention fundamentally overcomes the problem of limited airflow direction caused by the single vertical air outlet of existing desktop tower fans by setting two sets of independently rotating fans vertically within the same fixed frame. The two sets of fans can be angled by their rotating seats within the arc-shaped groove of the fixed frame, so that their air outlets face different directions. This allows a single tower fan to send airflow in two or more different directions at the same time, significantly expanding the effective airflow coverage area. It is suitable for scenarios where multiple users are seated side by side on a desktop, and can effectively meet the needs of multiple people to receive comfortable airflow at the same time.

[0021] Example:
[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a desktop tower fan, including a base 1, a fixed frame 2 rotatably connected to the top of the base 1, and two sets of fans 3 installed inside the fixed frame 2; a rotating seat 4 is rotatably connected to the outside of each fan 3, and the two sets of fans 3 are rotatably installed at the upper and lower ends of the fixed frame 2 respectively through the rotating seat 4; an installation groove is provided at the center of the fan frame on the front of each fan 3, and an infinite mirror light assembly is installed inside each installation groove.
[0023] One side of the rotating base 4 is connected to a pair of connecting seats 5 by fasteners, and each pair of connecting seats 5 is provided with a fixed shaft on the opposite side; the outer side of the fan 3 is provided with connecting strips, and both ends of the connecting strips are provided with fixing holes for insertion into the fixed shafts. The fixing holes and the fixed shafts are interference fit; this ensures that the fan 3 can rotate stably and smoothly around the fixed shafts, while ensuring the high strength, durability and stability of the connection points at the set angles, allowing users to accurately set the vertical air delivery angle.
[0024] The fixed frame 2 is composed of a rear frame 201 and a front frame 202. Both the upper and lower ends of the rear frame 201 and the front frame 202 are provided with arc-shaped grooves. The rotating seat 4 is circular and is fitted and snapped into the arc-shaped groove between the rear frame 201 and the front frame 202. The separate assembly structure of the rear frame 201 and the front frame 202 greatly facilitates the installation and maintenance of the internal components. The arc-shaped grooves provided on the upper and lower ends of the rear frame 201 precisely accommodate and limit the circular rotating seat 4. This not only stably constrains the position of the rotating seat 4, but more importantly, it provides a smooth, stable and controllable arc-shaped motion trajectory and guiding support for the left and right rotation of the rotating seat 4 and the fan 3 in the horizontal plane. This is the key to realizing the horizontal adjustment of the fan 3.
[0025] The base 1 is composed of a bottom shell 101 and a top cover 102. The top of the top cover 102 is provided with a rotating groove, and a turntable 6 is rotatably installed inside the rotating groove. The bottom ends of the rear frame 201 and the front frame 202 are both provided with base plates connected to the turntable 6. The base plates are fastened to the turntable 6 by fastening screws.

The connecting shaft passes through the through hole and is fixedly connected to the lower limiting plate 7. While transmitting rotational power, the limiting plate 7 effectively prevents the turntable 6 from axial displacement during operation, ensuring the smoothness and reliability of the rotational motion. The drive motor 9 directly drives the limiting plate 7, which can efficiently and accurately drive the turntable 6, the entire fixed frame 2, and the fan 3 to rotate horizontally, greatly expanding the horizontal coverage of the air supply and enabling automated air sweeping.
[0026] The bottom shell 101 houses a motherboard 8 and a battery 10. The motherboard 8 serves as the central control core, coordinating and managing the start / stop and wind speed of the dual fans 3 and the rotation of the drive motor 9. The motherboard 8 is electrically connected to the fans 3, drive motor 9, and battery 10. The built-in battery 10 provides a long-lasting and stable internal power supply, significantly enhancing the product's portability and freedom of use from cable constraints. The motherboard 8 is equipped with a control component and a display component. The control component consists of multiple sets of touch buttons, and the display component is a screen. The top cover 102 has a touch panel near the touch buttons on the motherboard 8 and an opening near the screen for it to be exposed. A charging socket is also installed on one side of the motherboard 8, and a charging port is provided on the top cover 102 at the corresponding charging socket location.
[0027] The Infinity Mirror lighting assembly includes a reflector 12, a light strip 13, and a coated glass 11. The reflector 12 is fixedly installed at the bottom of the mounting slot, the coated glass 11 is fixedly installed at the opening of the mounting slot, and the light strip 13 is fixedly installed on the inner circumferential wall of the mounting slot, located between the reflector 12 and the coated glass 11.
