Description

Technical Field

[0001] This utility model belongs to the field of fan technology, and in particular relates to a fan with a nameplate built-in in a stable state. Background Technology

[0002] Currently, in traditional fans, the manufacturer's logo is printed directly in the center of the fan blade. When the fan blade rotates with the drive mechanism, the logo also rotates, making it difficult for the logo to be clearly seen by the user, which is not conducive to advertising. Utility Model Content

[0003] The purpose of this invention is to provide a fan built into the nameplate in a stable state, which aims to solve the technical problem in the prior art where the nameplate logo cannot be clearly displayed as the fan blades rotate.

[0004] To achieve the above objectives, this utility model provides a nameplate-mounted fan with a stable internal structure, comprising a nameplate, a bracket, a connecting shaft, a drive device, and fan blades. The bracket extends upwards around its periphery to form a mounting portion. A vertically upward connecting shaft is provided within the mounting portion. The drive device is mounted on the mounting portion and sleeved on the connecting shaft. The fan blades are also sleeved within the connecting shaft and connected to the drive device to drive the fan blades to rotate. The inner end face of a first bearing is sleeved on the connecting shaft, and the outer end face of the first bearing is connected to the inner end of the fan blades. The top end of the connecting shaft is fixedly connected to the nameplate by a locking device.

[0005] Furthermore, the lower end of the nameplate is provided with a nameplate fixing piece, which is fixed around the connecting shaft; the nameplate fixing piece is provided with a positioning groove, and the upper end of the connecting shaft is provided with a limiting boss that connects to the positioning groove.

[0006] Furthermore, a limiting boss is set inside the positioning groove, and a retaining ring is set around the positioning groove and engages with the limiting boss to form a locking connection, so as to lock the entire nameplate fixing piece between the retaining ring and the first bearing.

[0007] Furthermore, the fan blade includes an impeller housing and multiple blades distributed on the outer edge of the impeller housing, and the impeller housing is provided with a placement cavity with an open bottom.

[0008] Furthermore, the top wall of the impeller housing is provided with a central tube mounting hole for connection with the bearing.

[0009] Furthermore, the drive unit is installed in the placement cavity and includes a stator and a rotor. The stator is fixed on the mounting part, the rotor is rotatably sleeved on the stator, and the upper end face of the rotor is fixedly connected to the fan blades and drives the fan blades to rotate under electromagnetic action.

[0010] Furthermore, there is a movable cavity between the rotor and the fan blade. The movable cavity is provided with a first bearing, a spring and a second bearing in sequence from top to bottom. The inner end face of the second bearing is sleeved on the connecting shaft, and the outer end face of the bearing is connected to the inner end of the fan blade. The spring separates the two bearings to avoid interference.

[0011] The technical solution of the nameplate with built-in fan in steady state provided in this embodiment of the utility model has at least one of the following technical effects:

[0012] In this practical nameplate-mounted fan, the first step is to vertically install the connecting shaft within the mounting section of the bracket. The drive unit (motor) is then fitted onto the connecting shaft and fixed to the mounting section, ensuring a good fit between the drive unit and the connecting shaft. The fan blades are fitted onto the connecting shaft and connected to the connecting shaft and the inner end of the fan blades via a first bearing, ensuring smooth rotation of the fan blades. Finally, a locking device secures the nameplate to the top of the connecting shaft, ensuring that the nameplate does not rotate with the fan blades during fan operation. When the power is turned on, the drive unit starts, the fan blades begin to rotate, while the nameplate remains stationary, displaying a clear logo. Through this unique stable structural design, the nameplate can remain stationary relative to the fan blades, thus ensuring that the manufacturer's logo and other information on the nameplate are clearly visible to the user.
