Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a bladeless fan. Background Technology

[0002] A bladeless fan is an innovative type of fan. Unlike traditional fans, a bladeless fan does not have exposed blades to propel air. Instead, it works using aerodynamic principles. The bladeless fan has an air inlet at the bottom, which draws in air and then ejects it at high speed through a ring-shaped outlet.

[0003] For example, an existing patent, application number 202510460034.7, discloses a bladeless fan with humidification and purification functions. The fan includes a main body, which comprises a housing and a fan assembly, a filter assembly, and a humidification assembly disposed within the housing. The housing has an air inlet. An air outlet is also present on the main body, having an air inlet channel for introducing airflow generated by the fan assembly and an air outlet for discharging the airflow. When the bladeless fan operates, the airflow enters the housing through the air inlet, passes sequentially through the filter assembly, the humidification assembly, the fan assembly, and the air inlet channel, and then exits through the air outlet. The bladeless fan can selectively activate a humidification mode. However, the air outlet in this patent is an annular outlet, and apart from the fan's regular oscillation, the angle of the annular outlet is fixed. Therefore, there is still room for improvement in the fan's air outlet angle and coverage.

[0004] Therefore, it is necessary to invent a bladeless fan to solve the above problems. Utility Model Content

[0037] This utility model discloses a bladeless fan.

[0038] like Figure 1 and 2 As shown, the device includes a main unit 1. A vertical air duct 2 is installed on the top of the main unit 1. The bottom end of the air duct 2 is inserted into the interior of the main unit 1. An adapter 3 is sealed and connected to the top end of the air duct 2. A diversion box 4 is rotatably installed on one side of the adapter 3 and is driven to rotate by the adapter 3. The rotation axis is horizontal. Two air outlet pipes 5 are sealed and connected to the two ends of the diversion box 4 away from the adapter 3. The air outlet pipes 5 have an "L" shape structure. The "L" shaped air outlet pipe 5 includes a short section and a long section. The short section of the air outlet pipe 5 is connected to the diversion box 4 and its axis is horizontal. The long section of the air outlet pipe 5 extends outward from the end connected to the diversion box 4. The two air outlet pipes 5 are symmetrically arranged with respect to the center of the diversion box 4. The long sections of the two air outlet pipes 5 form a straight line. A rotating base 6 is installed at the bottom of the main unit 1 for the bladeless fan to swing. The swing axis is vertical.

[0039] like Figure 2 and 3As shown, the main unit 1 has an internal cavity, and a fan 7 is installed inside the cavity. The output end of the fan 7 is sealed and connected to an air guide shroud 10. The output end of the air guide shroud 10 is sealed and connected to an air guide pipe 2. An air inlet 9 is provided on the housing of the main unit 1. The fan 7 draws air, and the air flows from the outside of the main unit 1 through the air inlet 9, the fan 7, the air guide shroud 10, the air guide pipe 2, the adapter 3, the distribution box 4, and the air outlet pipe 5, and is output from the output end of the air outlet pipe 5. The fan 7 is hidden inside the main unit 1 to achieve air blowing, which has a high degree of safety.

[0040] like Figure 3 and 4 As shown, in some embodiments, a fan cover 8 is also included, which covers the outside of the fan 7 and has an input end and an output end. The fan 7 is sealed and connected to the air guide cover 10 through the output end of the fan cover 8.

[0041] like Figure 5 As shown, the fan 7 includes an air guide shroud 701 and a mixed-flow fan 702. The mixed-flow fan 702 is fixedly installed at the bottom of the air guide shroud 701. The mixed-flow fan 702 includes a motor and fan blades. The motor of the mixed-flow fan 702 is fixedly connected to the air guide shroud 701. The fan blades are driven by the motor to rotate independently. The mixed-flow fan 702 is existing technology and therefore will not be described in detail here. The air guide shroud 701 includes a base plate and a guide plate. The base plate has a tapered structure that is narrow at the top and wide at the bottom. Several guide plates are installed on the outside of the base plate. A guide channel is formed between two adjacent guide plates. An air guide port 11 is opened at one end of the guide channel near the mixed-flow fan 702 for air to pass through.

[0042] like Figure 3 and 5 As shown, the mixed-flow fan 702 draws air, and the air flows out through the gap between the fan 7 and the fan cover 8, as well as the air guide 701. The air guide 701 diverts and guides the airflow to improve the smoothness of the airflow and increases the air pressure to improve the air output efficiency.

[0043] like Figure 5 As shown, in some embodiments, the bottom plate surface of the air guide shroud 701 is provided with a plurality of air guide holes 12 to reduce obstruction of the airflow of the mixed flow fan 702 and improve the air output efficiency.

[0044] like Figure 4 As shown, the rotating base 6 is used to drive the fan to swing, which is a conventional existing technology and therefore will not be described in detail here. This includes, but is not limited to, using a gear set to adapt the oscillating motor to drive the swing.

[0045] It also includes a protective cover 13, which covers the drive mechanism of the rotating base 6 and provides protection for it. The top of the protective cover 13 has several heat dissipation holes 14 for heat dissipation of electrical components.

[0046] like Figure 2 and 6 As shown, the adapter 3 has a first adapter air duct 15 inside. The two ends of the first adapter air duct 15 pass through the shell of the adapter 3 and connect to the outside. The two ends of the first adapter air duct 15 are perpendicular. One end is connected to the air guide pipe 2, and the other end is connected to the inner cavity of the diversion box 4. The inner cavity of the diversion box 4 is provided with a partition 16, which divides the inner cavity of the diversion box 4 into two diversion air ducts 17. Both diversion air ducts 17 are connected to the inner cavity of the first adapter air duct 15. The input ends of the two air outlet pipes 5 are respectively sealed and connected to the output ends of the two diversion air ducts 17. This utility model sets up a diversion box 4 and two air outlet pipes 5 for air output. The diversion design reduces the airflow path in the air outlet pipes 5, thereby improving the air output efficiency.

[0047] like Figure 6 As shown, a motor 18 is installed inside the adapter 3. The output end of the motor 18 coincides with the rotation axis of the diverter box 4. The output end of the motor 18 is coaxially connected to a rotating shaft 19. The end of the rotating shaft 19 is fixedly connected to the diverter box 4. The diverter box 4 is driven to rotate by the motor 18, thereby realizing the rotation of the air outlet pipe 5 and realizing the adjustment of the air outlet angle. The air outlet angle is flexible and versatile and covers a wide range.

[0048] like Figure 7 As shown, the inner cavity of the "L"-shaped short section of the air outlet duct 5 is provided with a second transition air duct 20. The end of the second transition air duct 20 passes through the end of the short section of the air outlet duct 5 and is used to connect with the branch air duct 17. The inner cavity of the "L"-shaped long section of the air outlet duct 5 is provided with an air outlet duct 21, which is connected to the second transition air duct 20. An air outlet 22 connected to the air outlet duct 21 is provided on one side of the long section of the air outlet duct 5 along its length direction. Several diversion plates 23 are provided in the inner cavity of the air outlet duct 21 along its length direction. The diversion plates 23 are located on the side close to the air outlet 22 for air diversion, thereby improving the uniformity of air outlet.

[0049] In some embodiments, the air outlet duct 21 gradually narrows from the air inlet end to the opposite end cavity, further improving the uniformity of air outlet 22 in each area.

[0050] 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.
