[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] An air circulator fan includes a rear cover 1, fan blades 2, a front cover 5, and a front baffle 6. The fan blades 2 are installed inside the rear cover 1, and a limiting mechanism 3 is provided on the outer side of the rear cover 1. A base mechanism 4 is installed outside the limiting mechanism 3. The front cover 5 is installed on one side of the rear cover 1, and the front baffle 6 is installed inside the front cover 5. The base mechanism 4 includes a base frame 41. A latch 42 is provided on one side of the base frame 41, and a rotation limiting groove 43 is provided on the inner side of the base frame 41. A rubber ring 44 is fixedly connected to the bottom end of the base frame 41. A rubber post 45 with a threaded hole is fixedly connected to the bottom end of the base frame 41. An anti-slip component 46 is provided at the bottom end of the base frame 41. A strap component 47 is provided at the bottom end of the base frame 41, and a screw-on fixing component 48 is installed at the bottom end of the strap component 47.

[0032] As a further implementation of this solution, a number of rotation limiting grooves 43 are provided. The multiple rotation limiting grooves 43 are evenly and equidistantly distributed in a circular array. The position of the rotation limiting grooves 43 corresponds one-to-one with a number of protrusions provided on one side of the limiting mechanism 3. A part of the limiting mechanism 3 is inserted into the bayonet 42. This design can ensure that the device can rotate at a certain angle and stop at a specific position, which is beneficial for adjusting the air outlet angle of the equipment.

[0033] As a further implementation of this solution, the central axis of the rubber ring 44 and the central axis of the threaded rubber column 45 are on the same straight line. The diameter of the rubber ring 44 is twice the diameter of the threaded rubber column 45. The anti-slip component 46 is a square in the vertical direction. The anti-slip component 46 is set on the side of the strap assembly 47 near the base frame 41. The screw fastener 48 is spirally connected to the threaded rubber column 45 and the base frame 41. This arrangement can make the connection between the components more stable. At the same time, the anti-slip component 46 can improve the anti-slip effect of the device when it is fixed on other components.

[0034] As a further implementation of this solution, the anti-slip component 46 includes a rubber plate 461, an inter-plate groove 462 on the inner side of the rubber plate 461, a long rod 463 on the inner side of the inter-plate groove 462, and a rubber sheet 464 fixedly connected to the outer side of the long rod 463 by adhesive bonding. A limit groove 465 is formed on the inner side of the rubber plate 461, a side groove 466 is formed on the inner side of the rubber plate 461, an adhesive plate 467 is fixedly connected to one side of the rubber plate 461, and anti-slip holes 468 are fixedly connected to the inner side of the adhesive plate 467. The rubber sheet 461 is fixedly connected to one side of the rubber sheet 464, and the long rod... A gap is provided between the outer side of 463 and the inner side of the inter-plate groove 462. The side groove 466 is opened above the connection between the rubber 464 and the rubber plate 461. Several anti-slip holes 468 are provided. The multiple anti-slip holes 468 are evenly distributed in a rectangular array on the inner side of the adhesive plate 467. The connection between the rubber 464 and the long rod 463 allows the inter-plate groove 462 to be quickly exposed when the long rod 463 is squeezed, thereby increasing the friction between the rubber plate 461 and the contact surface. The limiting groove 465 can prevent slippage between the anti-slip component 46 and the strap component 47.

[0035] As a further implementation of this solution, the strap assembly 47 includes a rubber strap 471. One side of the rubber strap 471 is fixedly connected to a Velcro 472 by adhesive. One end of the rubber strap 471 is equipped with an iron ring 473. A rubber washer 474 is fixedly connected to one side of the rubber strap 471. A portion of the rubber strap 471 is disposed in a limiting groove 465. The rubber washer 474 is embedded between the rubber ring 44 and the threaded rubber post 45. There are two rubber washers 474, and the positions of the two rubber washers 474 correspond one-to-one with the positions of the screw fastener 48. The arrangement of the rubber strap 471, Velcro 472, and iron ring 473 enables the components to be quickly fixed. The design of the rubber washer 474 being embedded between the rubber ring 44 and the threaded rubber post 45 makes the strap assembly 47 more stably connected to the base frame 41 by the screw fastener 48.

[0036] Workflow: First, install the fan blade 2 inside the rear cover 1. Then, snap the front cover 5 into the rear cover 1. Next, install the front baffle 6 into the front cover 5. Align the limiting mechanism 3 with the bayonet 42 to mount the rear cover 1 onto the base mechanism 4. If the device needs to be used on a stable table, the rubber ring 44 fixedly connected to the bottom of the base frame 41 can contact the table to prevent slipping. Then, rotate the rear cover 1. When 11 rotates, the relative positions of the different rotation limiting grooves 43 and the limiting mechanism 3 change, which can change the blowing angle of the device. If the device needs to be fixed on a wobbly table or an unstable place, the anti-slip component 46 can be attached to the bottom of the base frame 41. Then, fix the strap component 47 to the base frame 41 by screwing on the fixing component 48. At this time, the rubber washer 474 is stuck between the rubber ring 44 and the threaded rubber post 45, which further improves the connection stability between the rubber strap 471 and the base frame 41. The rubber strap 471 presses the long rod 463 in the limiting groove 465, causing the long rod 463 to penetrate into the inter-plate groove 462 and causing the rubber sheet 464 to deform. This makes the inter-plate groove 462 improve the anti-slip properties of the rubber sheet 461 surface and increase the friction when the rubber sheet 461 contacts other objects. At the same time, the adhesive plate 467 contacts the base frame 41. The anti-slip hole 468 prevents slippage between the adhesive plate 467 and the base frame 41. One end of the rubber strap 471 is passed through the iron ring 47. 3. By attaching the two Velcro pieces 472 together, the device can be fixed. When the device needs to be removed, simply rotate the screw fastener 48 to separate the screw fastener 48 from the base frame 41 and the threaded rubber post 45, and then remove it from one side of the strap assembly 47. At this time, the long rod 463 will be reset by the force generated by the elastic deformation of the rubber 464. At the same time, the dust on the surface of the rubber 464 will slide into the side groove 466 to ensure the cleanliness of the device surface.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
