Description

Technical Field

[0001] This utility model relates to the field of gear shifting technology, specifically to a fan switch that switches the wind speed via a gear shift lever. Background Technology

[0002] With the rapid development of modern home technology, home appliances have gradually become an important part of family life. Among them, fans, as an indispensable appliance in the home, are receiving increasing attention from users for their ease of operation, comfort, and design. To meet diverse usage needs, fans are usually equipped with multiple wind speeds for users to choose from, adapting to different temperatures and environments.

[0003] Traditional fans primarily rely on button or knob switches to switch fan speeds. While this design is simple and practical, it has several shortcomings in actual operation. First, button or knob switches often wear out or break after prolonged use, especially in high humidity or dusty environments, where the failure rate increases further. Second, due to the insufficient feedback mechanism of traditional button or knob switches, users may misoperate when switching fan speeds or have difficulty accurately sensing the current fan speed setting, thus affecting the user experience.

[0004] Furthermore, traditional fan switch designs often lack personalization and innovation, making it difficult to meet the aesthetic and usage requirements of modern consumers for home appliances. In the high-end market and among young consumers, traditional fan switch designs struggle to gain a significant competitive advantage, thus limiting the product's market potential.

[0014] The swing arm is equipped with a storage slot, and the magnetic element is installed in the storage slot.

[0015] The beneficial effects of this utility model are:

[0016] By setting a stop lever at the other end of the drive shaft, the operating stroke between different gears can be increased, thereby enhancing the sense of operation; at the same time, the longer the stop lever, the greater the operating stroke, and the stronger the sense of operation.

[0017] By setting a limiting hole on the housing, the drive shaft is limited to rotate within the limiting hole. A receiving groove for preventing the rolling balls is installed on the drive shaft. The inner wall of the limiting hole is provided with one or more damping grooves. The rolling balls are set in the damping grooves. When switching gears, the rolling balls switch between several damping grooves, increasing the tactile feedback during switching. Attached Figure Description
