Description

Technical Field

[0001] This utility model relates to the field of air circulation equipment, and in particular to a multi-segment tower fan with a limit memory rotation mechanism. Background Technology

[0002] Existing technology, such as Taiwan Patent TW113207882U, discloses a tower fan structure capable of multi-directional airflow. This structure uses multiple housing units connected in series, and each housing unit is rotated via upper and lower planar bearings, allowing the tower fan to output airflow in multiple directions. However, this technology still has the following shortcomings:

[0003] No angle limit structure: When users adjust the airflow direction of each section, it is easy to rotate beyond the angle, causing the air outlet pointing error, and may even damage the internal wiring or cause the structure to jam.

[0004] No rotation memory function: The tower fan needs to be manually readjusted after each power outage, which is cumbersome and results in a poor user experience.

[0005] Therefore, there is an urgent need to provide a structural improvement scheme with limit and rotation memory functions, which can achieve memory locking of the air outlet direction while maintaining segmented rotation, thereby improving the practicality and personalized control capability of multi-segment tower fans.

[0013] Preferably, the magnetic positioning element has an adsorption and holding force of 0.5–1.2 N, which can resist self-repositioning and stably maintain the set direction.

[0014] Preferably, a lower limit memory rotation mechanism is provided between the base and the first housing unit to control the limiting and memory of the overall direction of the tower.

[0015] Preferably, each housing unit is equipped with an independent limit memory rotation mechanism, which can realize segmented air supply angle memory control.

[0016] Preferably, the fan assembly is connected to the air ducts in each housing unit through the main air duct, and the air is drawn in by the base and discharged from each air outlet through each air duct.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This multi-segment tower fan with a limit memory rotation mechanism can maintain the rotation angle position of each segment through a magnetic adsorption positioning structure, so that the user does not need to adjust it again next time, realizing independent wind direction memory for multiple segments and no readjustment after power failure.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a multi-segment tower fan with a limit memory rotation mechanism, including a base (1), multiple shell units (2) connected in sequence, a fan assembly (3), and a limit memory rotation mechanism (4) disposed between each shell unit (2).

[0028] Multiple housing units (2) are rotatably connected relative to each other by a rotating connection structure (41), which can be an upper plane bearing or a rotating bracket, capable of supporting 360-degree or limited angle rotation.

[0029] The limiting structure (42) is provided between every two adjacent shell units, including a stop block (421) and a limiting groove (422). The limiting groove (422) is an arc-shaped track structure with limiting endpoints at both ends, and the rotation range is limited to 60-120 degrees to prevent over-rotation and jamming.

[0030] To address the issue of wind direction loss after a power outage and restart, a memory structure (43) is provided near the limiting structure. In this embodiment, a magnetic positioning method is used. The memory structure (43) includes a magnet (431) on the first housing unit and a metal positioning piece (432) on the second housing unit. When the user adjusts the angle to the desired position, the magnet (431) and the positioning piece (432) attract each other, achieving physical locking.

[0031] The magnetic force is controlled between 0.5 and 1.2 N, which is sufficient to maintain the angular positioning without hindering the user's manual adjustment.

[0032] In addition, a lower limit memory rotation mechanism (44) is provided between the base (1) and the first housing unit to record the main direction of the entire tower fan body. This structure can be linked with the main control chip or implemented by mechanical locking to ensure the consistency of the overall wind direction reset.

[0033] The fan assembly (3) is installed inside the base (1). The fan guides the airflow into the air ducts of each housing unit (2) through the main air duct and discharges it through the air outlet. The air outlet angle of each housing unit can be controlled independently. The user can set the three sections to 0°, 60° and –60° respectively to achieve a three-way air supply range.

[0034] This structure is suitable for high-end personalized tower fans, smart fans, or zoned air supply scenarios, improving air supply flexibility, user operation convenience, and product technology added value.
