Description

Technical Field

[0001] The utility model belongs to the technical field of household fan shaking head mechanisms, and in particular relates to an adjustable fan shaking head mechanism. Background Art

[0002] In traditional fan designs, the shaking head mechanism often adopts a fixed structure, that is, when the fan is designed and manufactured, its shaking head angle range is preset and fixed, and cannot be adjusted according to actual usage requirements. Although this type of fixed shaking head angle design is relatively simple in production and manufacturing and has relatively low cost, its applicability is greatly limited. Specifically, when users need to enjoy directional and concentrated air supply in a smaller space, such as next to an office desk or at the head of a bed in the bedroom, the existing fixed large-range shaking head design may cause wind dispersion and cannot effectively meet the needs of local cooling or air circulation. On the contrary, in open large spaces, such as living rooms or conference rooms, the fixed small-range shaking head design makes it difficult to achieve full circulation and uniform distribution of air, affecting the overall comfort and use effect.

[0003] In summary, the fan design with a fixed shaking angle in the prior art has obvious deficiencies in adapting to different usage environments or meeting the personalized needs of users, which limits the versatility and market competitiveness of fan products. Therefore, developing an adjustable fan shaking mechanism that can adjust the shaking angle width according to actual needs has become an important direction for improving user experience and expanding market applications. Utility Model Content

[0004] In order to solve the above technical problems, the utility model solves them through the following technical solutions.

[0005] An adjustable fan shaking mechanism includes a motor seat and an assembly seat, wherein the motor seat is equipped with a rotating shaft, the rotating shaft is connected to an eccentric plate, the eccentric plate is connected to a connecting rod, and the connecting rod is rotatably connected to the assembly seat. An eccentric dial is detachably mounted on the eccentric plate, an eccentric shaft is arranged on the eccentric dial, and the eccentric shaft is rotatably connected to the connecting rod. The design can adjust the eccentric distance a between the eccentric shaft and the rotating shaft through the eccentric dial, and the change of the eccentric distance a directly affects the swing amplitude of the connecting rod, thereby realizing a wide adjustment of the fan shaking angle, which can not only meet the needs of local air supply in a small range, but also adapt to the scene of all-round air supply in a large space.

[0006] Preferably, the eccentric plate is fixedly equipped with a clamping shaft, the clamping shaft is fixedly equipped with a clamping block, and the eccentric dial is provided with a clamping slot for assembling with the clamping block.

[0009] Preferably, the assembly seat is provided with an adjustment slot, a fixing slot is provided on one side of the adjustment slot, a fixing pin is installed in the fixing slot, the connecting rod is installed in the adjustment slot through a rotating pin, and the fixing pin fixes the position of the rotating pin.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figures 1 to 5 An adjustable fan shaking mechanism includes a motor base 10 and an assembly base 20. The motor base 10 is equipped with a rotating shaft 11, and the rotating shaft 11 is connected to an eccentric plate 12. The eccentric plate 12 is connected to a connecting rod 13, and the connecting rod 13 is rotatably connected to the assembly base 20. An eccentric dial 30 is detachably mounted on the eccentric plate 12, and an eccentric shaft 31 is provided on the eccentric dial 30, and the eccentric shaft 31 is rotatably connected to the connecting rod 13. This design can adjust the eccentric distance a between the eccentric shaft 31 and the rotating shaft 11 through the eccentric dial 30. The change of the eccentric distance a directly affects the swing amplitude of the connecting rod 13, thereby realizing a wide adjustment of the fan shaking angle, which can not only meet the needs of local air supply in a small range, but also adapt to the scene of all-round air supply in a large space.

[0024] Specifically, the eccentric plate 12 is fixedly equipped with a card shaft 14, the card shaft 14 is fixedly equipped with a card block 15, and the eccentric dial 30 is provided with a card slot 32 assembled with the card block 15. This design can easily adjust the eccentricity a. When the user needs to adjust the fan shaking angle, it is only necessary to move the eccentric dial 30 downward so that the card block 15 is disengaged from the card slot 32, and the eccentric dial 30 can be freely rotated to achieve accurate adjustment of the eccentricity a. This step is not only easy to operate, but also because the card block 15 is accurately matched with the card slot 32, after the adjustment is completed, the eccentric dial 30 is moved up again so that the card block 15 slides into the card slot 32, which can firmly lock the position of the eccentric dial 30, prevent the eccentricity a from changing due to external force or misoperation, and ensure the stability and durability of the fan shaking angle setting.

[0025] Furthermore, the clamping shaft 14 is connected with a spring 16 for pulling the eccentric dial 30. When the user adjusts the eccentric distance a and releases the clamping block 15, the spring 16 automatically applies a restoring force to pull up the eccentric dial 30, so that the clamping block 15 enters a predetermined position in the clamping slot 32.

[0026] In addition, the block 15 is prism-shaped. The prism-shaped design can provide a stable limit for the eccentric dial 30. Each edge of the prism-shaped block 15 can form a good contact with the wall of the slot 32, ensuring that the block 15 maintains precise guidance and support during the sliding and positioning process, effectively avoiding shaking or falling off during the rotation process, thereby limiting the eccentric dial 30.

[0027] In order to cooperate with the adjustment design of the eccentric dial 30, an adjustment slot 21 is provided on the assembly seat 20, a fixed slot 22 is provided on one side of the adjustment slot 21, a fixed pin 24 is installed in the fixed slot 22, and the connecting rod 13 is assembled in the adjustment slot 21 through the rotating pin 23, and the fixed pin 24 fixes the position of the rotating pin 23. Specifically, the smaller the eccentricity a is, the smaller the angle of the fan's rotation and shaking, and the larger the eccentricity a is, the larger the angle of the fan's rotation and shaking. At the same time, the farther away the fulcrum of the connecting rod 13 and the adjustment slot 21 are from the fan, the smaller the angle of the fan's rotation and shaking, and the closer the fulcrum of the connecting rod 13 and the adjustment slot 21 are to the fan, the larger the angle of the fan's rotation and shaking. By combining the design of the adjustment slot 21 with the eccentric dial 30, the adjustment of the fan's shaking mechanism is more precise, and the fan's rotation and shaking can be controlled at any angle between 0° and 170°.

[0028] In order to further improve the stability and durability of the structure, the motor base 10 and the assembly base 20 can be fixed with reinforced connectors, such as high-strength bolts or quick-release fasteners, which not only ensures the reliable connection between the components, but also facilitates future maintenance and cleaning. At the same time, the motor base 10 is designed with a shock-absorbing gasket, which can effectively absorb the vibration generated by the operation of the motor, reduce noise, and improve the overall quietness of the fan when it is running, providing users with a more comfortable living environment.

[0029] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
