Any embodiment or design scheme described as "exemplary" or "for example" in this utility model should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0019] In this invention, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between the related objects, indicating that three relationships can exist.

[0020] like Figures 1-8 As shown, a fan with grating animation effect includes: a front grille 1 and a rear grille 2, which are fastened together to define an accommodating area; a hollow shaft 3 fixed to the center of the rear grille 2, with a fan wheel 4 sleeved on the portion of the hollow shaft 3 extending into the accommodating area, the fan wheel 4 being rotatably connected to the hollow shaft 3; a grating plate 5, fixed to the center of the front grille 1, with a support 6 provided in the accommodating area, the support 6 being fixed to the grating plate 5, and an image plate 7 being rotatably connected to the side of the support 6 near the grating plate 5, and the pattern on the image plate 7 being projected horizontally onto the grating plate 5 to form a dynamic image of the pattern; a driving member, provided on the support 6, with the driving end of the driving member connected to the image plate 7 to make the image plate 7 rotate coaxially relative to the grating plate 5, the driving member being an electrically driven structure, and the power wire 13 of the driving member passing through the hollow shaft 3.

[0021] This invention uses a hollow shaft 3 to fix the power wire 13, allowing the drive component used to drive the image plate 7 to rotate to be electrically connected, ensuring the driving effect on the image plate 7. This avoids the need to set a wiring groove on the front cover 1, without damaging the appearance of the original fan structure, thus improving the overall integrity of the fan structure and enhancing its aesthetic appeal. By rotating the image plate 7 and projecting the pattern onto the grating plate 5, a dynamic image of the pattern on the image plate 7 is formed during user operation, thereby improving the user's viewing experience when using the fan.

[0022] Specifically, controlling the rotation of the image plate 7 independently through the driving component is beneficial for regulating the rotation speed of the image plate 7. After the image is analyzed frame by frame by the raster plate 5, the viewing experience of the generated dynamic image can be effectively improved.

[0023] Furthermore, the grating plate 5 is a transparent plate, and a plurality of grating strips 8 are provided on the grating plate 5. The plurality of grating strips 8 are equally spaced outward from the center and are distributed radially. The plurality of grating strips 8 cooperate to define the grid area on the grating plate 5, and the pattern of the image plate 7 is projected into the grid area. In this case, the pattern on the image plate 7 has gaps in the projection area of ​​the grating strip 8 along the horizontal direction.

[0024] The transparent grating plate 5 is used to project the pattern on the image plate 7 onto the front cover 1, and the pattern on the image plate 7 has a cavity corresponding to the projection coverage area of ​​the grating strip 8. When the pattern is directly projected into the grating area, the rotating image plate 7 and the grating strip 8 move alternately to form a dynamic effect of alternating layers of deep-light-deep, thereby improving the user's viewing experience.

[0025] Furthermore, the number of frames in the grating plate 5 is not less than 2.

[0026] Specifically, according to the formula (width of a single grating stripe + width of a single grating gap pixel = number of frames × width of a single grating gap pixel), the number of display frames of the grating plate 5 can be controlled when printing the grating strip 8.

[0027] Furthermore, the rotation speed of the image plate 7 is 60±25 revolutions per minute.

[0028] The image plate 7 is rotated by a driving component, and the rotation speed of the image plate 7 can be easily adjusted by controlling the image plate 7 independently through the driving component.

[0029] Furthermore, a collar 9 is integrally formed and fixed to the outer periphery of the grating plate 5. The collar 9 extends into the receiving area, and the support 6 is embedded in the collar 9. A step 10 is provided on the outer side wall of the support 6. The collar 9 abuts against the step 10 so that a gap is provided between the support 6 and the grating plate 5, and the image plate 7 is transferred into the gap.

[0030] By using the collar 9 and the step 10, the support 6 is nested and fixed to the grating plate 5, and the drive component is fixedly supported by the support 6. At the same time, the image plate 7 is rotatably connected to the support 6, ensuring the rotational stability of the image plate 7 and making the image plate 7 fit the grating plate 5, which is beneficial to improving the image clarity.

[0031] Furthermore, the driving components include: The rotating motor 14 is fixed to the outer wall of the support 6. The rotating motor 14 does not contact the wind turbine 4, and the rotating motor 14 is connected to the power wire 13. The reduction gear set 15 has a cavity inside the support 6. The reduction gear set 15 is rotatably fitted in the cavity. The input end of the reduction gear set 15 is coaxially fixed to the output shaft of the rotating motor 14, and the output end of the reduction gear set 15 is fixed to the axis of the image plate 7.

[0032] The rotating motor 14 is fixedly supported by the support 6, and the driving force of the rotating motor 14 is transmitted to the image plate 7 through the reduction gear set 15, thereby controlling the rotation of the image plate 7 independently. Specifically, according to the fixed transmission ratio of the reduction gear set 15, the speed of the rotating motor 14 is controlled to meet the speed requirements of the image plate 7. The transmission principle of the reduction gear set 15 is a conventional technical means and will not be described in detail.

[0033] Specifically, a sealed bearing 16 is connected to the side of the support 6 near the grating plate 5, a connecting post 17 is fixed to the center of the image plate 7, and the connecting post 17 is inserted into the inner ring side of the sealed bearing 16 for fixation. The output end of the reduction gear set 15 is coaxially fixed to the connecting post 17, driving the image plate 7 to rotate at a specific speed.

[0034] Furthermore, it also includes: A hollow motor 18 is fitted outside the hollow shaft 3. A base plate 19 is fixedly connected to the center of the rear mesh cover 2. The hollow motor 18 is fixedly connected to the base plate 19, and the hollow shaft 3 is fixedly connected to the base plate 19. The drive shaft 20 of the hollow motor 18 is rotatably connected to the hollow shaft 3 through a bearing. The impeller 4 is fitted and fixed to the outer periphery of the drive shaft 20.

[0035] The hollow motor 18 and the hollow shaft 3 are fixedly supported by the base plate 19, and the drive shaft 20 of the hollow motor 18 is sleeved on the outside of the hollow shaft 3. The drive shaft 20 is rotatably connected to the hollow shaft 3 through the bearing, so that the drive shaft 20 is used to drive the fan wheel 4 to rotate, which meets the user's wind power needs. At the same time, it keeps the inside of the hollow shaft 3 relatively stable, which is conducive to the stable support of the wire 13 passing through the hollow shaft 3, enhancing the overall integrity of the fan structure and avoiding the need to open the wiring channel on the front grille 1.

[0036] Furthermore, a through hole 11 is provided in the center of the base plate 19, and the hollow shaft 3 is connected to the through hole 11. The machine cover 12 is fixed to the side of the base plate 19 away from the rear mesh cover 2, and one end of the power wire 13 extends into the machine cover 12 and is connected to an external power source.

[0037] The hollow shaft 3 is connected to the machine cover 12 through the through hole 11 on the base plate 19, which facilitates the routing of the power wire 13 to meet the power requirements of the rotating motor 14.

[0038] This utility model also provides a working principle for a fan with raster animation effects: By fastening and fixing the front grille 1 and the rear grille 2 together, the rotating motor 14 is connected to the controller (not shown in the figure) inside the housing 12 by the power cable 13, so as to drive the image plate 7 to rotate at a constant speed. The pattern on the image plate 7 is projected onto the grating plate 5. As the image plate 7 rotates, a dynamic image of the pattern is formed, which enhances the visual experience of the fan structure. Furthermore, the hollow shaft 3 and the hollow motor 18 work together to drive the impeller 4 to rotate and provide airflow. The hollow shaft 3 is fixed on the base plate 19 to ensure the stability of the support for the power cable 13, and avoids opening a cable channel on the front grille 1 to destroy the integrity of the fan, thereby improving the user experience.
