[0039] In view of the technical problems described in the background art, a clamping type supercharged mixed flow fan is proposed, which mainly includes a clamping device 1, a rotating device 4, a connecting bracket 5 and a fan head 6.

[0040] refer to Figure 4 The clamping device 1 comprises a first clamping body 2 and a second clamping body 3. The first and second clamping bodies 2 and 3 are connected by a torsion spring, allowing them to open under external force and then be clamped to the edge of the tabletop by the torsion spring. The second clamping body 3 is designed to have a storage space to facilitate the installation of components or devices.

[0041] The rotating device 4 is installed in the second clamp 3. The rotating device 4 is connected to the connecting bracket 5, and the connecting bracket 5 is connected to the fan head 6. Under the drive of the rotating device 4, the fan head 6 is indirectly driven to rotate, rotating to supply air, increasing the air supply range of the fan head 6, and meeting the user's usage needs.

[0042] The connecting bracket 5 is used to connect the rotating device 4 and the fan head 6. At least a portion of the connecting bracket 5 is hinged to the fan head 6 bracket, so that the fan head 6 can rotate relative to the connecting bracket 5, thereby adjusting the air outlet direction of the fan head 6. Preferably, the connecting bracket 5 has a U-shaped structure, with both ends of the connecting bracket 5 hinged to the fan head 6.

[0043] The fan head 6 is used to drive and generate airflow. The fan head 6 mainly includes a first housing 7, a second housing 8, a first motor 9 and fan blades 10.

[0044] like Figure 7 , the first shell 7 includes a motor mounting seat 12, a first pressure plate 13 and a first outer ring 11, the motor mounting seat 12 and the first outer ring 11 can be integrally formed or be independent components, the motor mounting seat 12 can be set at the air inlet end position or the air outlet end position of the first outer ring 11, as a feasible technical method, the motor mounting seat 12 and the first outer ring 11 are integrally formed and the motor mounting seat 12 is set at the air outlet end of the first outer ring 11, the first pressure plate 13 can be evenly distributed or unevenly distributed between the first outer ring 11 and the motor mounting seat 12, preferably, the first pressure plate 13 is uniformly distributed on the circumference, due to the presence of the first pressure plate 13, the radial ventilation area of ​​the airflow passing through the first outer ring 11 becomes smaller, and the first shell 7 is located at the air inlet end, the airflow can absorb the airflow around it and increase the air volume; at the same time, the airflow is pressurized and the airflow speed is increased.

[0045] like Figure 8 The second housing 8 includes a second outer ring 15, a pressurizing seat 16, and a second pressurizing plate 17. These may be integrally formed or separate components. Preferably, they are integrally formed. The second housing 8 may be integrally formed with the first housing 7 or separate components. The second pressurizing plate 17 may be evenly or unevenly distributed between the second outer ring 15 and the pressurizing seat 16. Preferably, the second pressurizing plate 17 is evenly distributed around the circumference. The presence of the second pressurizing plate 17 in the second speed-increasing air duct 18 reduces the radial ventilation area of ​​the airflow passing through the second outer ring 15, further pressurizing the airflow and increasing its velocity.

[0046] In this way, by setting up a double speed-increasing air duct form, when the flow passes through the first speed-increasing air duct 14, the first pressure plate 13 set in the first speed-increasing air duct 14 causes the radial ventilation area to become smaller to achieve pressurization of the airflow. At the same time, the first speed-increasing air duct 14 is located at the air inlet end, thereby being able to absorb the surrounding air and increase the air volume; when the airflow passes through the second speed-increasing air duct 18, the second pressure plate 17 set in the second speed-increasing air duct 18 causes the radial ventilation area to become smaller, and the airflow is further pressurized and blown out in the second stage, thereby increasing the air volume and air supply distance.

[0047] like Figure 10 As shown, the circumferential position of the motor mounting seat 12 is provided with a first transition surface 19 that radially increases from the air inlet direction to the air outlet direction; the circumferential position of the boost seat 16 is provided with a second transition surface 20 that radially increases from the air inlet direction to the air outlet direction; the first transition surface 19 and the second transition surface 20 are arranged in contact with each other to form a uniformly transitioned arc surface or inclined surface to guide the airflow.

[0048] As a preferred embodiment, the outer circumference of the motor mounting seat 12 is provided with a first transition surface 19 from the air inlet direction to the air outlet direction, and the outer circumference of the boost seat 16 is provided with a second transition surface 20 from the air inlet direction to the air outlet direction. The first transition surface 19 and the second transition surface 20 are radially enlarged and arranged close to each other from the air inlet direction to the air outlet direction. Through this structural setting, the first transition surface 19 and the second transition surface 20 are close to each other to form an arc surface form or a slope form, and there is no gap between the first transition surface 19 and the second transition surface 20. On the one hand, the airflow is guided to be blown out through the first transition surface 19 and the second transition surface 20 during the blowing process. Due to its radially enlarged structure, the airflow can be pressurized, the wind pressure of the airflow can be increased, and the air supply distance can be increased. On the other hand, since the first transition surface 19 and the second transition surface 20 are close to each other, the wind noise can be reduced and the airflow can be guided to be blown out.

[0049] The second outer ring 15 is provided with a third transition surface 21 radially contracting from the air inlet direction to the air outlet direction near the air outlet direction. The third transition surface 21 and the second transition surface 20 focus and pressurize the airflow.

[0050] A radially contracting third transition surface 21 is provided on the inner wall of the second outer ring 15 close to the air outlet direction. The third transition surface 21 may be an arc surface or an inclined surface. Structurally, since the second transition surface 20 is radially enlarged and the third transition surface 21 is radially contracted, a necking shape is formed. When the airflow passes through the second transition surface 20 and the third transition surface 21, the airflow is pressurized, the wind pressure of the airflow is increased, and the air supply distance is increased.

[0051] like Figure 7-8As shown, the first pressure plate 13 is distributed clockwise or counterclockwise from the air inlet end to the air outlet end, so that the first pressure plate 13 of the first speed-increasing air duct 14 guides the airflow in the forward direction or gathers the airflow in the reverse direction to the second speed-increasing air duct 18, and the second pressure plate 17 is distributed counterclockwise or clockwise from the air inlet end to the air outlet end, so that the second pressure plate 17 gathers the airflow in the reverse direction or blows it out in the forward direction, thereby achieving the effect of pressurizing and gathering the airflow.

[0052] In one practicable embodiment, the first pressure plate 13 is arranged in a clockwise direction and the second pressure plate 17 is arranged in a counterclockwise direction. As the airflow is driven by the fan blades 10, the airflow moves centrifugally along the surrounding directions of the fan blades 10. The first pressure plate 13 of the first speed-increasing air duct 14 is arranged in a direction opposite to the direction of the airflow. The first pressure plate 13 gathers the wind moving in the surrounding directions and changes the flow direction of the airflow. The airflow passing through the first speed-increasing air duct 14 is guided to the second speed-increasing air duct 18. The second pressure plate 17 of the second speed-increasing air duct 18 is arranged in a counterclockwise direction. Since the counterclockwise arrangement of the second pressure plate 17 is the same as the direction of the airflow, the second pressure plate 17 guides the gathered airflow and blows the air through the second speed-increasing air duct 18 out in a forward direction. This avoids the airflow being dispersed and blown out, resulting in air volume loss, and achieves the effect of wind gathering and pressure increase.

[0053] In another feasible manner, the first pressure plate 13 is arranged counterclockwise and the second pressure plate 17 is arranged clockwise. As the airflow is driven by the fan blades 10, the airflow moves centrifugally along the four directions of the fan blades 10. The first pressure setting direction of the first speed increasing duct 14 is the same as the direction of the airflow movement. The first pressure plate 13 guides and pressurizes the wind moving in all directions. Since the clockwise setting of the second pressure plate 17 is opposite to the direction of the airflow movement, the second pressure plate 17 can gather the airflow and change the flow direction of the airflow, so that the airflow can be blown out from the front when it is blown out, avoiding the airflow being dispersed and causing air volume loss.

[0054] like Figure 11-13 As shown, the first motor 9 includes a stator 22 and a rotor 23. The stator 22 is fixed to the motor mounting base 12, and the rotor 23 is arranged on the fan blade 10. The rotor 23 is sleeved on the stator 22. In practice, the first motor 9 can be a brushed motor or a brushless motor.

[0055] The motor mounting seat 12 is provided with a boss 24 extending axially and hollow inside; the fan blade 10 includes a hub portion 25 and blades 26 evenly arranged on the outer peripheral surface of the hub portion 25, and the hub portion 25 has a receiving portion 27 recessed inwardly; the stator 22 includes an iron core 28 inserted on the boss 24 and a coil 29 wound on the iron core 28; the rotor 23 includes a rotating shaft 30 axially arranged on the receiving portion 27 and a magnetic ring 31 attached to the radial inner wall of the receiving portion 27, and the rotating shaft 30 is inserted in the boss 24.

[0056] Preferably, as an implementable technical solution, the first motor 9 adopts an outer rotor brushless motor. Structurally, the hub portion 25 of the fan blade 10 is provided with a storage portion 27, and the fan blade 10 is used as the installation position of the rotor 23. The magnetic ring 31 and the rotating shaft 30 of the rotor 23 are arranged at the storage portion 27 position, thereby optimizing the structure and saving the number of components. At the same time, a hollow boss 24 is provided on the motor mounting seat 12 to facilitate the insertion of the rotating shaft 30 into the boss 24 for positioning. At the same time, the iron core 28 and the coil 29 of the stator 22 can be sleeved on the boss 24 for positioning. The fan blade 10 is driven by the designed outer rotor brushless motor structure, which can be more compact in structure, save the number of components, and thus reduce costs.

[0057] like Figure 6 As shown, a cover 32 is provided on one side of the boost seat 16 close to the air outlet end. There is an installation space between the cover 32 and the boost seat. A first digital display panel 33 is provided in the installation space. The first digital display panel 33 is used to display and / or control parameters.

[0058] To facilitate the clamp-on supercharged mixed flow fan, a mounting space is provided on the supercharger base 16. A first digital display panel 33 is disposed within the mounting space. The first digital display panel 33 can be designed to control the rotation of the first motor 9 and the rotation of the rotating device 4. During use, the fan can be powered externally using a power cord, with the user controlling the drive through the first digital display panel 33. Alternatively, the fan can be powered by a built-in battery. Preferably, the battery can be built into the supercharger base 16. At the same time, the first digital display panel 33 can display the battery charge level.

[0059] As shown in the figure, it includes an air inlet grille 34, and the air inlet grille 34 is provided with a hollow accommodating portion 35 along the air inlet end to the air outlet end, and at least a portion of the accommodating portion 35 extends to the first shell 7 or the second shell 8; to form a package that wraps the first shell 7 or the first shell 7 and the second shell 8, or to form a package that is accommodated in the first shell 7 or the first shell 7 and the second shell 8.

[0060] An air inlet grille 34 is added. The air inlet grille 34 is a hollow structure forming a receiving portion 35. The air inlet grille 34 can be set on one side of the first housing 7. In a first embodiment, the air inlet grille 34 can accommodate the first housing 7 and the second housing 8 through the receiving portion 35. In a second embodiment, the air inlet grille 34 can accommodate the first housing 7 through the receiving portion 35. In a third embodiment, the receiving portion 35 of the air inlet grille 34 can be accommodated within the first housing 7 and the second housing 8. In a fourth embodiment, the receiving portion 35 of the air inlet grille 34 can be accommodated within the first housing 7. Preferably, the present invention adopts the fourth embodiment, and the air inlet grille 34 is used to prevent foreign matter from entering the interior of the fan head 6.

[0061] like Figure 15-16 As shown, the rotating device 4 includes a second digital display panel 36 arranged inside the second clamp 3, a second motor 37 arranged inside the second clamp 3 and electrically connected to the second digital display panel 36, and a rotating member 38 arranged on the output end of the second motor 37; the rotating member 38 is fixedly connected to the connecting bracket 5, and the second motor 37 drives the connecting bracket 5 to rotate.

[0062] In implementation, the rotating device 4 mainly includes a second digital display panel 36, a second motor 37 and a rotating member 38. The second digital display panel 36 can be designed to control the rotation of the second motor 37. The output end of the second motor 37 is provided with a rotating member 38. The rotating member 38 is fixedly connected to the connecting bracket 5. When the second motor 37 rotates, it drives the connecting bracket 5 to rotate. Since the fan head 6 is hinged on the connecting bracket 5, the rotation of the fan head 6 is indirectly realized, thereby increasing the air supply range of the fan head 6.
