Technical Field

[0001] This utility model relates to the field of amplitude flow fan technology, and in particular to a single-phase AC amplitude flow fan. Background Technology

[0002] A fan is a device that converts mechanical energy into the kinetic or potential energy of a gas through a mechanical means. It is mainly used for the transportation, ventilation, exhaust, cooling, and heating of air or other gases. Amplitude-flow fans are primarily used in air conditioning systems of vehicles. Single-phase AC refers to the fan's motor being powered by a single-phase AC power supply. To save costs and facilitate maintenance, a single-phase AC amplitude-flow fan is required.

[0003] A single-phase AC amplitude flow fan is a type of fan that uses a single-phase AC power supply. In previous technologies, the internal filter structure of the fan was usually fixed, making it difficult to disassemble and clean. Prolonged use may lead to blockage and increase the operating resistance of the fan, making it inconvenient to use. Utility Model Content

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a single-phase AC amplitude flow fan, comprising an air outlet box 1, a filter plate 2 slidably connected inside the air outlet box 1, a handle 3 fixedly connected to the upper surface of the filter plate 2, a retaining bead 4 slidably connected inside the filter plate 2, the outer wall of the retaining bead 4 being engaged inside the air outlet box 1, a limiting post 5 fixedly connected to the outer wall of the retaining bead 4, the outer wall of the limiting post 5 slidably connected to inside the filter plate 2, a spring 6 provided on the outer wall of the limiting post 5, one end of the spring 6 being fixedly connected to the outer wall of the retaining bead 4, the other end of the spring 6 being fixedly connected to inside the filter plate 2, and a support assembly provided on the outer wall of the air outlet box 1;

[0026] Specifically, the air outlet box 1 has an air outlet for the fan to output air. Inside the air outlet box 1 is a filter plate 2 for dust filtration. Two handles 3 are located above the filter plate 2. When the filter plate 2 needs to be removed, it can be pulled out by gripping the handles 3. Pulling the handles 3 causes the filter plate 2 to slide inside the air outlet box 1. The sliding of the filter plate 2 causes the retaining beads 4 to slide inside the air outlet box 1. A groove inside the air outlet box 1 limits the retaining beads 4, allowing for quick installation of the filter plate 2. A limiting post 5 on the outer wall of the retaining beads 4 limits the spring 6. The spring 6 rebounds, causing the retaining beads 4 to press against the air outlet box 1, thus achieving quick installation and removal of the filter plate 2. This allows for timely and regular cleaning of the filter plate 2, preventing clogging and effectively preventing dust.

[0027] Reference Figure 2 The support assembly includes a fixed box 7, the outer wall of the fixed box 7 is fixedly connected to the outer wall of the air outlet box 1, and a fixed box 8 is fixedly connected to the outer wall of the fixed box 7.

[0028] Specifically, the air outlet box 1 serves to fix the fixed box 7, and the fixed box 7 serves to fix the fixed box 8. The fixed box 7 and the fixed box 8 are used to support the internal structure of the fan and protect it.

[0029] Reference Figure 4 , Figure 5 and Figure 6 A motor 9 is fixedly connected to the outer wall of the fixed box 7. A rotating shaft 10 is fixedly installed at the output end of the motor 9. The outer wall of the rotating shaft 10 is rotatably connected to the inside of the fixed box 7. An impeller 11 is fixedly connected to the outer wall of the rotating shaft 10 and is located inside the fixed box 7. A rotating plate 12 is fixedly connected to the outer wall of the rotating shaft 10. A rotating shaft 13 is fixedly connected to the inside of the rotating plate 12. A connecting rod 14 is rotatably connected to the outer wall of the rotating shaft 13. A connecting shaft 15 is rotatably connected to the inside of the connecting rod 14. A rotating plate 16 is fixedly connected to the outer wall of the connecting shaft 15. A fixed shaft 17 is fixedly connected to the inside of the rotating plate 16. The outer wall of the fixed shaft 17 is rotatably connected to the inside of the air outlet box 1. An oscillating blade 18 is fixedly connected to the outer wall of the fixed shaft 17.

[0030] Specifically, the fixed box 7 serves to fix the motor 9. By starting the motor 9, the rotating shaft 10 can be driven to rotate inside the fixed box 7. The fixed box 7 supports the rotating shaft 10. The rotating shaft 10 drives the impeller 11 to rotate, and the impeller 11 can blow air when it rotates. The rotating shaft 10 can drive the rotating plate 12 to rotate, and the rotating plate 12 can drive the rotating shaft 13 to revolve around the rotating shaft 10. The rotating shaft 13 can drive the connecting rod 14 to rotate, and the connecting rod 14 can drive the connecting shaft 15 to oscillate back and forth. The connecting shaft 15 can drive the rotating plate 16 to oscillate back and forth, and the rotating plate 16 can drive the fixed shaft 17 to oscillate back and forth. The fixed shaft 17 can drive the swing blade 18 to oscillate back and forth. The swing blade 18 has a guiding effect, which can accelerate the airflow. It shares a drive motor 9 with the impeller 11, which can save costs.

[0031] Working principle: When the radial flow fan is needed, the motor 9 is started to drive the rotating shaft 10 to rotate inside the fixed box 7. While the rotating shaft 10 is rotating, it can drive the impeller 11 to rotate inside the fixed box 7, thereby driving the fan to work. When the rotating shaft 10 rotates, it can drive the rotating plate 12 to rotate. The rotating plate 12 can drive the rotating shaft 13 to rotate, and at the same time drive the connecting rod 14 to rotate, thereby driving the connecting shaft 15 to swing back and forth. At the same time, it can drive the rotating plate 16 to swing back and forth, thereby driving the fixed shaft 17 to move back and forth inside the air outlet box 1, and at the same time driving the swing blade 18 to swing back and forth, achieving the effect of automatically driving the swing blade 18 to swing.

[0032] When it is necessary to disassemble the handle 3, the filter plate 2 can be slid inside the air outlet box 1 by directly pulling the handle 3. At the same time, the retaining bead 4 can be slid out of the groove opened inside the air outlet box 1, and the spring 6 can be compressed, thereby causing the limiting post 5 to slide inside the filter plate 2. When the filter plate 2 slides out of the air outlet box 1, the handle 3 can be quickly disassembled, so that the handle 3 can be cleaned regularly to prevent blockage. This fan can not only drive the swing blade 18 to swing automatically when driving the fan, thereby achieving the effect of automatic air diversion, but also achieve the effect of quickly disassembling the filter plate 2, so as to clean the filter device inside the fan in a timely manner.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
