Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to a fan with adjustable angle. Background Art

[0002] An electric fan is a common electrical appliance that uses an electric motor to drive the impeller to rotate to accelerate the circulation of air. It is mainly used for cooling down and circulating air, bringing great convenience to people's lives.

[0003] For example, the Chinese patent document with publication number CN221074697U discloses a desktop fan with up and down and left and right swinging functions, including a desktop base, a head assembly rotatably connected to the desktop base through a connecting rod assembly; the fan head assembly is connected to the front end of the head assembly, and the two form a transmission match; the head assembly includes a head support base, a fan blade motor fixed at the front end of the head support base, a swing motor arranged inside the head support base, an electric control assembly arranged at the upper end of the head support base, and left and right swing rods transmission-connected to the swing motor; the connecting rod assembly includes at least a fixed connecting rod and a swing connecting rod, which is fixedly connected and installed on the desktop base, and the swing connecting rod is movably connected to the fixed connecting rod; the upper end of the swing connecting rod is provided with a rotation center hole and a swing fulcrum; the fan blade assembly is provided with a motor core shaft downward, and the motor core shaft is inserted into the rotation center hole; the output ends of the left and right swing rods are connected to the swing fulcrum.

[0004] In the technical solution of the above patent document, the fan head assembly is connected to the front end of the machine head assembly, and the machine head assembly is rotatably connected to the desktop base through the connecting rod assembly. Therefore, only the connecting rod assembly supports the fan head assembly and the machine head assembly. The upper end is heavy and prone to instability during long-term use. After manually adjusting the fan assembly to swing up and down to the target angle, the fixed block needs to be inserted into the corresponding gear slot to keep the position of the machine head assembly relative to the connecting rod assembly stable, and the operation is relatively troublesome.

[0005] The Chinese patent document with publication number CN221347351U discloses a dual-purpose small fan that can be wall-mounted or used vertically, comprising: a U-shaped fan base having a flat bottom end surface, a plurality of ground support feet being arranged on the bottom end surface, and a wall-mounting hole being arranged on the bottom end surface; a fan housing is rotatably matched with the upper end of the U-shaped fan base through an angle gear mechanism; a fan blade assembly is arranged in the fan housing; a switch member is arranged on the back of the fan housing; the angle gear mechanism comprises a guide groove and a rotation hole arranged at the U-shaped fan base, a fixed gear plate installed on the U-shaped fan base, and a plurality of A gear slot is provided on the fixed gear plate and is annularly distributed around the rotating hole, a rotating shaft and guide ribs are formed on the fan cover, and a movable stopper and a spring are located between the fixed gear plate and the fan cover; the rotating shaft is inserted into the rotating hole so that the fan cover can rotate relative to the U-shaped fan base with the rotating shaft as the rotation center; the guide rib is always inserted in the guide slot and can move along the guide slot; the movable stopper can be inserted into any gear slot; the spring abuts between the fan cover and the movable stopper, so that the stopper always has a movement tendency close to the fixed gear plate.

[0006] In the technical solution of the above patent document, the fan blade assembly is arranged in the fan housing, and the fan housing is rotatably connected with the upper end of the U-shaped fan base through the angle gear mechanism, that is, the two ends of the fan housing are connected to the upper end of the U-shaped fan base, so that the fan remains stable when rotating; and by manually adjusting the angle gear mechanism, the spring in the angle gear mechanism acts on the movable positioning member, and a preload is always provided, which has a good damping texture when switching gears, and after the gear adjustment, the movable fixed member can be continuously and reliably in the gear, meeting the different air outlet requirements of users, and no additional manual operation of the fixed gear is required, which is easy to operate. However, the U-shaped base is relatively bulky, and the U-shaped base can only be connected to the fan assembly through the two connection points at the upper end, so that only fans of a single size and the base can be supplied on the production line for matching connection. If you want to supply fans of different sizes, you need to redesign and manufacture base molds of different sizes, which greatly increases the cost, making the base insufficiently versatile, which is not conducive to mass production and assembly.
