Description

Technical Field

[0001] This utility model relates to a car wash machine, and more particularly to a suspended swing car wash blower. Background Technology

[0002] Existing car wash systems use fans to dry the car body after washing. The fans are usually located at the top of the car wash system, that is, above the car body, to dry the top of the car.

[0003] For example, Chinese patent CN106945646A discloses a drying device for a car wash machine. Its air knife structure is complex and it can only blow air in one direction. The effect on the sides of the car body is poor, and it needs to be combined with a side blowing device, which results in a complex overall structure and high manufacturing cost.

[0004] For example, CN204567585U discloses a car wash machine drying system, which includes two side drying devices and a horizontal drying device located at the top. The side drying devices are used for drying the sides of the vehicle body and require side air ducts and horizontal air ducts, making the overall structure more complex and costly. Utility Model Content

[0005] To solve the above problems, this utility model provides a suspended swing car wash blower, the specific technical solution of which is as follows:

[0006] A suspended oscillating car wash blower includes a blower motor, a drive motor, and centrifugal fan blades fixed on the blower motor. It also includes: a blower frame, with the drive motor symmetrically mounted on both sides of the blower frame; a rotating shaft rotatably mounted on the blower frame; a volute fixed on the rotating shaft and connected to the blower motor, with the centrifugal fan blades movably disposed within the volute; and an eccentric linkage device connected to both the volute and the drive motor, so as to drive the volute to oscillate reciprocally via the drive motor.

[0007] Preferably, the eccentric linkage device includes: a first connecting shaft disposed on the volute housing; a first spherical bearing disposed on the first connecting shaft; a first connecting rod with one end disposed on the first spherical bearing; a second spherical bearing disposed on the other end of the first connecting rod; a second connecting shaft disposed on the second spherical bearing; and an eccentric connecting rod disposed on the drive motor and connected to the second connecting shaft.

[0008] Preferably, the eccentric connecting rod is provided with a plurality of eccentric holes, and the eccentric holes are connected to the eccentric connecting rod.

[0009] Preferably, the vortex shell is provided with a plurality of reinforcing plates, and the reinforcing plates are also connected to the rotating shaft.

[0010] Preferably, it further includes: a connecting sealing plate, which is connected to the blower motor and the vortex housing respectively.

[0011] Furthermore, the connecting plate includes: a first connecting plate disposed on the first connecting hole of the vortex shell; a first connecting cylinder disposed at one end on the first connecting plate; and a second connecting plate disposed at the other end of the first connecting cylinder and connected to the blower motor; wherein the second connecting plate is also located inside the vortex shell.

[0012] Furthermore, the diameter of the first connecting hole is larger than the outer diameter of the centrifugal fan blade.

[0013] Preferably, it further includes: a bearing housing, disposed on the blower frame and connected to the rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention provides a suspended swing car wash blower that drives the vortex shell to swing through a drive motor and an eccentric linkage device, thereby enabling effective air blowing on both sides of the car body to achieve air drying, improving the air drying effect. It also has a simple structure and does not require a side air drying device, which greatly reduces the cost. Attached Figure Description

[0024] The present invention will now be further described with reference to the accompanying drawings.

[0025] like Figures 1 to 8 As shown, a suspended swing car wash blower includes a blower motor 3, a drive motor 6, centrifugal fan blades, a volute 1, a blower frame 8, a rotating shaft 5, and an eccentric linkage device 7. The drive motor 6 is symmetrically installed at both ends of the blower frame 8 and connected to the volute via the eccentric linkage device 7. The volute is rotatably mounted on the blower frame 8 via the rotating shaft 5. The blower motor 3 is fixed to one side of the volute 1 and connected to the centrifugal fan blades, which are movably located inside the volute 1. The drive motor 6 drives the volute 1 to swing back and forth around the axis of the rotating shaft 5 via the eccentric linkage device 7, realizing swing blowing. This means that the angle of the air outlet of the volute 1 can be adjusted, allowing the air outlet to blow towards both sides of the car body, increasing the blowing coverage and thus improving the drying effect. It eliminates the need for a separate side drying device, as well as horizontal and side air ducts, and only requires rotating the volute 1, greatly simplifying the structure and reducing costs.

[0026] The eccentric linkage device 7 includes a first connecting shaft 74, a first spherical bearing 72, a first connecting rod 71, a second spherical bearing 73, a second connecting shaft, and an eccentric connecting rod 75 connected in sequence. The first connecting shaft 74 is fixed to the side of the volute housing 1, and the eccentric connecting rod 75 is mounted on the drive motor 6. Both ends of the first connecting rod 71 are connected to the first spherical bearing 72 and the second spherical bearing 73 by threads. The eccentric connecting rod 75 drives the volute housing 1 to reciprocate.

[0027] To facilitate adjustment of the swing angle of the vortex housing 1, i.e., to facilitate adjustment of the blowing angle range, a plurality of eccentric holes 751 are provided on the eccentric connecting rod 75. The eccentric holes 751 are arranged along the length direction of the eccentric connecting rod 75 and are connected to the eccentric connecting rod 75. The eccentric holes 751 are used to adjust the eccentric distance, thereby realizing the adjustment of the swing angle range of the vortex housing 1.

[0028] To improve the connection strength between the volute and the rotating shaft 5, and to enhance safety and reliability, several reinforcing plates 12 are provided on the volute 1. These reinforcing plates 12 are also connected to the rotating shaft 5. Three reinforcing plates 12 are provided; two are fixed to the connecting bosses 11 at both ends of the volute, and the other is welded to the middle position of the volute 1, making the connection between the volute 1 and the rotating shaft 5 more reliable.

[0029] For ease of assembly, a connecting plate 2 is included, which is connected to both the blower motor 3 and the volute housing 1. The connecting plate 2 comprises a first connecting plate 21, a first connecting cylinder 22, and a second connecting plate 23 connected in sequence. The first connecting plate 21 is mounted on the first connecting hole 13 of the volute housing 1. Both the first connecting plate 21 and the second connecting plate 23 are annular plates. The first connecting cylinder 22 is located between the first connecting plate 21 and the second connecting plate 23 to increase the axial depth. The second connecting plate 23 is connected to the blower motor 3. To facilitate the assembly of the centrifugal fan blades, the centrifugal fan blades can be first fixed to the blower motor 3 and then installed as a whole onto the volute housing 1. Therefore, the diameter of the first connecting hole 13 needs to be larger than the outer diameter of the centrifugal fan blades. The first connecting plate 21 has an arc-shaped mounting hole 211, which is fixed to the volute housing 1 by screws.

[0030] To improve the rotational flexibility of the vortex housing 1, reduce noise and friction, and extend service life, a bearing housing 4 is also included. The bearing is fixed on the blower frame 8 and connected to the rotating shaft 5. The bearing housing 4 is located at both ends of the rotating shaft 5.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
