Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a small desktop fan that is easy to clamp. Background Technology

[0002] Electric fans are commonly used electrical appliances in daily life and work. Electric fans are divided into ceiling fans and table fans. Table fans are generally placed on stable surfaces such as desktops. However, table fans will vibrate during use and take up space above the desktop, affecting the user's use. Placing the table fan on the edge of the desktop also poses a risk of falling, causing damage to the electric fan and resulting in economic losses for the user. Therefore, we propose a small desktop fan that is easy to clamp. Utility Model Content

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Combined with appendix Figures 1-4 A small desktop fan that is easy to clamp includes a fan body, a flexible support rod 4, a fixing base 3, and a fixing clip. The fan body consists of a head 5, fan blades 6, a rear guard 7, a front guard 8, and a fixing ring 9. The fan blades 6 are distributed on the rotating shaft of the head 5. The rear end and front end of the fan blades 6 are provided with matching rear guards 7 and front guards 8. The fixing ring 9 is fitted onto the rear guards 7 and front guards 8. The flexible support rod 4 is provided below the head 5. This structure is commonly found in lazy phone holders and is conventional existing technology, so it will not be described in detail here. The lower end of the flexible support rod 4 is provided with a fixing base 3, and the lower end of the fixing base 3 is provided with a fixing clip.

[0020] The fan head 5 is electrically connected to an external power source and is rotatably connected to the upper end of the flexible support rod 4, which facilitates the adjustment of the airflow direction of the fan body. Users can bend the flexible support rod 4 as needed to adjust its height and position for user convenience. The fan head 5 is equipped with a cleaning device to remove dust adhering to the rear cover 7 at the air intake end of the fan body, reducing dust drifting towards the user.

[0021] The cleaning device includes a collar 15, a connecting rod 16, and a fixing clip 17. The collar 15 is fitted onto the head 5 and is rotatably connected to the head 5. The connecting rod 16 is provided on the side of the collar 15. The connecting rod 16 has bristles distributed on the side near the rear cover 7. The fixing clip 17 is provided at the upper end of the connecting rod 16. Rotating the collar 15 causes the connecting rod 16 to rotate around the collar 15. The bristles on the connecting rod 16 remove the dust from the rear cover 7. During the cleaning process, the dust falls or is carried away by the airflow, preventing the dust from being blown towards the user by the airflow.

[0022] The fixing clip 17 has an inverted U-shaped structure. The fixing clip 17 is set to cooperate with the fixing ring 9. The fixing clip 17 is fixed on both sides of the fixing ring 9. The fixing clip 17 is positioned above the connecting rod 16, so that the bristles on the connecting rod 16 can fully contact the rear cover 7.

[0023] The fixing clamp includes an upper clamping plate 1 and a lower clamping plate 2. The upper clamping plate 1 and the lower clamping plate 2 are hinged together. A torsion spring is provided at the hinge connection between the upper clamping plate 1 and the lower clamping plate 2. The fixing seat 3 is provided on the upper end face of the upper clamping plate 1. When the torsion spring is open, one end of the upper clamping plate 1 and the lower clamping plate 2 abut against each other, which facilitates clamping.

[0024] The inner walls of the closed ends of the upper clamping plate 1 and the lower clamping plate 2 are provided with soft anti-slip pads 14. The two anti-slip pads 14 are respectively clamped on the upper and lower ends of the tabletop to increase the stability of the clamping.

[0025] The lower clamping plate 2 is provided with a retaining ring 10 at its lower end, and a suction cup 11 is provided inside the retaining ring 10. The suction cup 11 moves up and down along the retaining ring 10. A lead screw 12 is provided above the suction cup 11. The lower end of the lead screw 12 is rotatably connected to the upper end of the suction cup 11. The upper end of the lead screw 12 passes through the lower clamping plate 2 and is threadedly connected to the lower clamping plate 2. A knob 13 is provided on the upper end of the lead screw 12. The suction cup 11 adheres to the fixing clamp on the table. By rotating the knob 13, the lead screw 12 moves down, thereby squeezing the suction cup 11, expelling the air inside the suction cup 11, and increasing the stability of the adsorption.

[0026] The embodiment describes a small desktop fan that is easy to clamp. In use, press one end of the upper clamp 1 and the lower clamp 2 opening to open the other ends. Then, clamp the fixing clip to the edge of the desktop. Two anti-slip pads 14 are clamped to the upper and lower surfaces of the desktop to increase clamping stability. Alternatively, the suction cup 11 can be fixed to the upper edge of the desktop, allowing the clamp to adhere to the desktop. By rotating the knob 13, the lead screw 12 moves downward, squeezing the suction cup 11 and expelling air from it, increasing suction stability. Then, turn on the fan body. During use, the fan head 5 can be rotated to adjust the airflow direction. The flexible support rod 4 can be bent as needed to adjust its height and position. When there is dust adhering to the rear cover 7, rotate the collar 15 to rotate the connecting rod 16 around the collar 15. The bristles on the connecting rod 16 remove the dust from the rear cover 7. During the removal process, the dust falls or drifts away with the airflow, preventing it from being blown towards the user.
