Description

Technical Field

[0002] Fans are common products in everyday life. To address the problem of fans requiring a flat surface for use, a lamp-like clamping assembly can be placed on the bottom of the fan. However, this clamping assembly can only be clamped to horizontal surfaces, not vertical surfaces, limiting its practical applications. Furthermore, since the fan itself has a certain weight, the clamping assembly is easily affected by gravity and the fan's rotation during use, causing the fan to wobble or move vertically when fixed to the vertical surface, making its safe use difficult to ensure.

[0003] Therefore, there is an urgent need for a clampable fan to solve the above problems. Utility Model Content

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figures 1 to 3As shown, this embodiment provides a clampable fan, comprising a fan body and a clamping assembly 4. The fan body includes a fan head 1 and a control and adjustment assembly. The fan head 1 is disposed at the upper end of the control and adjustment assembly, and the control and adjustment assembly is used to support and control the movement of the fan head 1. The clamping assembly 4 includes two clamping arms 41, a fixed shaft, and a spring. The spring and the middle sections of the two clamping arms 41 are both inserted into the fixed shaft and can rotate about the fixed shaft. The axial end of the fixed shaft is connected to the lower end of the control and adjustment assembly, thereby achieving connection between the clamping assembly 4 and the fan body. The spring is used to ensure that the first ends 411 of the two clamping arms 41 always have a force to press against each other, thereby forming a clamping portion of the clamping assembly 4, and to ensure that the second ends 412 of the two clamping arms 41 always have a force to separate from each other, thereby forming a separating portion of the clamping assembly 4. Pressing the separating portion can move the two second ends 412 closer together and the two first ends 411 farther apart, so that the two first ends 411 can be located on either side of a longitudinal fixed object. Releasing the pressure on the separating portion allows the clamping portion to clamp the longitudinal fixed object. In addition, N reinforcement grooves 413 are correspondingly provided at the first ends 411 of the two clamping arms 41. The reinforcement grooves 413 can divide the clamping portion into N+1 clamping sub-portions. That is, when the size of the clamping arm 41 remains unchanged, the number of clamping portions with the longitudinal fixed object can be increased by providing the reinforcement grooves 413, which can improve the fixing stability of the clamping portion and the longitudinal fixed object, and avoid shaking or longitudinal movement of the clamping portion when it is clamped on the longitudinal fixed object due to factors such as the weight of the fan and the rotation of the fan during use, thereby ensuring safety in use.

[0036] Optionally, when the number N of reinforcement grooves 413 is greater than 1, that is, when at least two reinforcement grooves 413 are provided, the at least two reinforcement grooves 413 are spaced apart along the axial direction of the fixed shaft. In a specific implementation, the width and number of reinforcement grooves 413 along the axial direction of the fixed shaft can be adjusted based on the axial dimension of the first end 411 of the clamping arm 41. The depth of the reinforcement grooves 413 can be adjusted to allow clearance of longitudinal fixtures.

[0037] Optionally, the inner wall surface 4131 of the reinforcement groove 413 has a curved corner, that is, the corner is rounded instead of a right angle. This configuration makes the stress distribution of the clamping portion more uniform, improves the strength and durability of the overall structure of the clamping assembly 4, and is more beautiful and easier to clean.

[0038] Optionally, the first ends 411 of the two clamping arms 41 are each provided with a triangular groove 4141, so that the clamping sub-section has a square groove 414 extending axially along the fixed axis. The square groove 414 is used to accommodate a longitudinal fixture. In a specific implementation, the width of the square groove 414 is determined based on the size of the longitudinal fixture. The longitudinal fixture is generally a cylindrical rod or a square rod. The width of the square groove 414 is adapted to the diameter of the cylindrical rod or the side length of the square rod, which facilitates the clamping of cylindrical and square rods and has a wider range of applications.

[0039] Optionally, anti-slip protrusions are provided on the inner wall of the square groove 414. In a specific implementation, the anti-slip protrusions can be small particles raised on the inner wall of the square groove 414, or can be horizontal zigzag patterns, thereby increasing the friction between the clamping sub-part and the longitudinal fixture, making the clamping assembly 4 more stable when fixed to the longitudinal fixture.

[0040] Optionally, an anti-skid pad is provided on the inner wall of the square groove 414. The anti-skid pad and the anti-skid protrusion can be provided selectively, and the anti-skid pad can be fixed in the square groove 414 by bonding, which is convenient for replacement.

[0041] In this embodiment, the control and adjustment component includes a control module 2 and an adjustment module 3. The upper end of the control module 2 is connected to the fan head 1, the lower end of the control module 2 is connected to the upper end of the adjustment module 3, and the lower end of the adjustment module 3 is connected to the fixed axis of the clamping component 4. The adjustment module 3 is used to adjust the angle between the fan head 1 and the horizontal plane, and the control module 2 is used to control the working mode of the fan head 1. During specific implementation, the control module 2 can control the fan head 1 to rotate and blow air or blow air in a fixed direction, and can also control the blowing level of the fan head 1, that is, the air volume. The adjustment module 3 can raise the fan head 1 to increase the angle between the fan head 1 and the horizontal plane, or lower the fan head 1 to reduce the angle between the fan head 1 and the horizontal plane, so that the blowing range of the clamped fan is wider.

[0042] Optionally, the adjustment module 3 includes an upper fixing member 31, a lower fixing member 32, and a connecting shaft 33. The upper fixing member 31 is connected to the lower end of the adjustment module 3, and the lower fixing member 32 is connected to the fixed shaft. The end of the upper fixing member 31 not connected to the adjustment module 3 and the end of the lower fixing member 32 not connected to the fixed shaft are rotatably connected via the connecting shaft 33. The connection angle between the upper fixing member 31 and the lower fixing member 32 is adjustable. In a specific implementation, when the clamping assembly 4 is fixed to the longitudinal fixture, the position of the clamping assembly 4 and the lower fixing member 32 is fixed, while the lower fixing member 32 is connected to the adjustment module 3, and the fan head 1 is disposed on the adjustment module 3. Then, by adjusting the connection angle between the upper fixing member 31 and the lower fixing member 32, the angle of the fan head 1 relative to the plane of the longitudinal fixture can be changed.

[0043] Optionally, the fan head 1 includes blades 12 and a housing 11. The blades 12 are disposed within the housing 11, which is secured to the control module 2. The blades 12 are rotatably connected to the control module 2. The blades 12 are electrically connected to the control module 2. When the control module 2 controls the rotation of the fan head 1, the control module 2 rotates relative to the adjustment module 3 and the clamping assembly 4, thereby driving the rotation of the fan head 1. When the control module 2 controls the airflow level of the fan head 1, the drive unit of the control module 2 drives the blades 12 to rotate. The faster the rotation speed of the blades 12, the greater the airflow.

[0044] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
