Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a circulating fan. Background Technology

[0002] Existing fans rely on a synchronous motor, crank, and connecting rod to tilt and oscillate the fan head. Because the center of gravity of the fan head is relatively high and the head is heavy, prolonged tilting and oscillation causes the connecting rod to continuously push and pull the synchronous motor shaft. All the force exerted by the connecting rod is applied to the synchronous motor shaft. Due to the structural limitations of the synchronous motor, it can only withstand a limited amount of force. Over time, the pushing and pulling action during automatic tilting and oscillation gradually loosens the synchronous motor shaft, leading to damage and reduced or malfunction of the tilting function. Furthermore, this type of structure, which simultaneously performs tilting and oscillation, is bulky and complex. Additionally, traditional fans and humidifiers are separate devices, and their functions cannot be combined into a single unit. To address this, existing water-cooled humidifying fans are used. However, existing humidifying fans involve setting up water tanks and pumps on the support components or control units, while the mist outlet is located on the fan head frame, delivering water from bottom to top. This requires increasing the volume of the support components or control units, and the water path is relatively long. Therefore, the humidification structure is more complex, larger in size, and more expensive. Furthermore, placing the mist outlet on the fan head frame or base affects the spraying effect. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-3As shown, a circulating fan includes a support assembly 1. A control assembly 2 is located at the upper end of the support assembly 1. A swinging connecting frame 3 is movably connected to the upper end of the control assembly 2 via a swinging component.

The fan heads 4 are eccentrically connected to the rocking synchronous motor 10. The swinging assembly includes a swinging frame 6 connected between the control assembly 2 and the connecting frame 3. A motor base 7 is fitted to the upper end of the swinging frame 6. A swinging synchronous motor 8 is mounted on the motor base 7. The swinging synchronous motor 8... The motor 10 and the oscillating synchronous motor 8 are controlled separately, so that the fan head 4 performs pitching and swaying movements respectively.

In addition, by placing the oscillating synchronous motor 10 between the connecting frame 3 and the fan head 4, and placing the oscillating synchronous motor 8 between the connecting frame 3 and the control component 2, and by placing the humidifying device 5 on the fan head 4, water is delivered from top to bottom. The water path is shorter, which can improve the spraying effect. This makes the overall structure simple and reasonable, with a small size, and can save costs.

[0022] In this embodiment, the swing frame 6 has a central connecting hole 61 in the middle, and two arc-shaped swing holes 62 are symmetrically arranged on both sides of the central connecting hole 61.

When the fan head 4 needs to swing left and right, the motor is controlled to rotate, so that the gear 73 meshes and rotates in the internal gear ring 63 of the swing frame 6. Since the swing frame 6 is fixed, when the gear 73 rotates, it rotates in an arc along the two arc-shaped swing holes 62 via the two swing rods 72, so that the motor base 7, the swing synchronous motor 8, the connecting frame 3 and the fan head 4 swing left and right together.

[0023] In this embodiment, the control component 2 includes a front control shell 21 and a rear control shell 22.

The output end of the shaking synchronous motor 10 is connected to one of the connecting heads 34. The shaking synchronous motor 10 is provided with a motor cover 35. The shaking of the fan head 4 directly drives the connecting head 34 to rotate through the shaking synchronous motor 10, so that the fan head 4 as a whole rotates and oscillates in accordance with the connecting frame 3.

[0026] In this embodiment, a base annular groove 36 for mounting the motor base 7 is formed between the front frame housing 31 and the rear frame housing 32.

This structure is simple and reasonable, with a small volume, and can effectively save costs.

[0030] In this embodiment, the water tank 51 includes an arc-shaped box body 511 that fits into the inner wall of the air inlet shell 41. The top of the arc-shaped box body 511 has a groove 512 that fits into a connecting post on the inner wall of the air inlet shell 41. An arc-shaped annular cavity 513 is formed at the front of the arc-shaped box body 511, and a fan-shaped cavity 514 communicating with the arc-shaped annular cavity 513 is formed inside the arc-shaped box body 511.
