Description

[Technical Field]

[0001] The present utility model is applied to the technical field of fan technology, and particularly relates to a desktop circulating fan. [Background Art]

[0002] As an air circulation device, a fan is a common cooling household electrical appliance in hot summer and is widely used in people's daily life.

[0003] At present, most of the oscillation modes of commercially available desktop fans adopt a crank structure, which can only perform linear reciprocating movement after being powered on. There are dead points in movement, large reciprocating inertia, high noise, low rotation service life, and inability to change direction rapidly.

[0004] Therefore, the present utility model provides a desktop circulating fan, which can effectively solve the above problems, transmits power through gears, can realize rapid direction change, and reduce noise. [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] In order to overcome the drawbacks of the prior art, the present utility model provides a desktop circulating fan, which transmits power through gears, can achieve high-speed direction change, and reduces noise. [Means for Solving the Problem]

[0006] The technical solution adopted by the present utility model to solve the problem is as follows.

[0007] A desktop circulating fan comprises the following components.

[0008] a fixed base

[0009] a horizontal rotation module. The horizontal rotation module is mounted on the fixed base and can perform 360-degree horizontal rotation relative to the fixed base.

[0010] Inversion module. The inversion module is connected to the horizontal rotation module and can be inverted 90 degrees vertically relative to the horizontal rotation module.

[0011] Blade. The blade is connected to the inversion module.

[0012] Eventually, the horizontal rotation module worked in conjunction with the vertical inversion module to enable multi-angle adjustment of the blade. [Effects of the Invention]

[0013] The effect of this new practical design is that, with the aforementioned structure installed, when in use, the base drive module drives the rotating cover, causing it to rotate left and right around the vertical axis Z, thereby changing the direction of the fan module. The inversion module then drives the fan module, causing it to rotate around the upward axis X, moving the fan joule up and down. The two movements combined allow for free adjustment of the direction of the fan module. When the fan motor starts, it drives the blades to rotate and generates airflow, and in conjunction with the operation of the base drive module and the inversion module, the direction of the airflow can be freely adjusted, resulting in a better overall performance of this product.

As used in this application, terms such as “vertical,” “horizontal,” “up,” “down,” “left,” and “right” are for illustrative purposes only and do not imply that they represent only one embodiment.

[0021] Figures 1 through 12 show one type of desktop circulating fan.

[0022] Fixed base 100

[0023] Horizontal rotation module 200. The so-called horizontal rotation module 200 is fixed to the fixed base 100 and can rotate horizontally 360 degrees relative to the fixed base 100.

[0024] The inversion module 300 is connected to the horizontal rotation module 200 and can be inverted 90 degrees vertically relative to the horizontal rotation module 200.

[0025] Blade 400. Blade 400 is connected to the inversion module 300.

[0026] Of these, the horizontal rotation module 200 works in cooperation with the vertical inversion module 300 to enable multi-angle adjustment of the blade 400.

[0027] With this structure installed, when in use, the base horizontal rotation module 200 drives the rotation cover 210, which rotates the rotation cover 210 left and right around the vertical axis Z, changing the direction of the fan module 400. Then, the up-and-down inversion module 300 drives the fan module 400, moving the fan joule 400 up and down. The two movements together allow the direction of the fan module 400 to be freely adjusted. The fan motor 410 starts up, driving the blades 430 to rotate and generate airflow, and the airflow can be adjusted in any direction by the movements of the horizontal rotation module 200 and the up-and-down inversion module 300. The effect is improved. Referring to Attached Figures 1 and 8, the product is in the first state. The fan module 400 is facing forward. Referring to Attached Figures 2 and 4, the product is in the second state. The fan module 400 is facing diagonally upward. Referring to Attached Figure 3, the product is in the third state. The fan module 400 is pointed straight upwards.

[0032] In this embodiment, the transmission component 340 is provided with a gear groove 342, and the transmission rack 341 is installed within the gear groove 342. The upper and lower drive gears 330 are inserted into the gear groove 342 and are movable within the gear groove 342. With this structure, the upper and lower drive gears 330 are inserted into the gear groove 342, and as the upper and lower drive gears 330 move along the transmission rack 341, the gear groove 342 moves within the gear groove 342, effectively protecting the upper and lower drive gears 330. In addition, a portion of the lubricating oil is contained within the gear groove 342, allowing the upper and lower drive gears 330 to mesh more smoothly with the transmission rack 341, resulting in smoother product movement and effective noise reduction.

An opening (321) is provided at the rear of the motor base (320), and the enclosure (423) is attached to the motor base (320) and closed over the opening (321). This structure allows the front fan cover (421) and the rear fan cover (422) to be removed. The blades 430, blade motor 410, and vertical rotation module 300 are easily assembled to the fan cover 420. This improves assembly efficiency.

[0036] In this embodiment, a positioning shaft (212) is located at the center of the swivel cover (210). A shaft hole (101) is drilled at the center of the fixed base (100). The positioning shaft (212) can rotate within the shaft hole (101). This structure allows the swivel cover 210 to rotate more smoothly relative to the fixed base 100 as the positioning shaft (212) rotates within the shaft hole 101. This enables the swivel cover 210 and the fixed base 100 to be positioned radially, allowing the base drive gear 230 to mesh with the inner ring gear 240 more stably.

[0037] In this embodiment, the horizontal rotation module 200 further includes a connecting cover 270. The connecting cover 270 is installed between the swivel cover 210 and the fixed base 100 and is connected to the swivel cover 210. The positioning shaft 212 extends downward along the lower surface of the connecting cover 270. This structure allows both the base motor 220 and the positioning shaft 212 to be connected to the connecting cover 270, making the structural layout of the product more rational, making the installation of the base motor 220 easier, increasing the assembly efficiency of the product, and further allowing the base drive gear 230 to mesh more stably with the inner ring gear 240.
