Description

Technical Field

[0001] This utility model relates to the field of swing mechanism technology, specifically to a multi-nozzle swing mechanism for a car swing-type cleaning machine. Background Technology

[0002] In the car wash industry, efficient, comprehensive, and meticulous cleaning results have always been the goal. Traditional car washing methods, such as manual washing, not only consume a lot of manpower and time, but also make it difficult to guarantee consistent cleaning quality. With the development of technology, various automated car wash machines have emerged, among which the oscillating washing machine has attracted attention because it can improve the cleaning coverage to a certain extent.

[0003] For example, Chinese patent CN108608997B discloses a gantry-type automatic car wash machine, including a chassis cleaning system located at the bottom of the gantry frame, a crossbeam slidably mounted on the longitudinal slide rail of the gantry frame, a fan unit mounted on the crossbeam, a slide table slidably mounted on the crossbeam, and a rotating mechanism mounted on the slide table. The rotating mechanism has a mounting frame connected to its rotating shaft. The mounting frame is equipped with a spray frame and a roller brush frame composed of a top rod and a side rod. The spray frame has nozzles connected to a liquid source. A roller brush is arranged along the roller brush frame. With the help of a matching rotating drive mechanism, the roller brush rotates and, together with the roller brush frame and the spray frame, circles around the car body to form a roller brush and spray cleaning structure, and, together with the fan, forms a wiping and drying structure.

[0004] However, the nozzle oscillation mechanism described above still has some problems:

[0005] First, the spray nozzle's swing angle and range are limited, making it impossible to completely cover all parts of the car, which can easily create blind spots and result in incomplete cleaning.

Multiple fixing plates 12, slots 13, first fixing cylinders 14, and second fixing cylinders 15 are provided at equal intervals and arranged at the lower end of the horizontal plate 11.

[0043] The drive assembly 21 includes a motor 211, a mounting plate 212, a rotating plate 213, a first connecting rod 214, a second connecting rod 215, a third connecting rod 216, and a fourth connecting rod 217. The mounting plate 212 is fixedly installed on the lower end of the horizontal plate 11. The motor 211 is fixedly connected to the mounting plate 212. The output end of the motor 211 is fixedly connected to one end of the rotating plate 213. The other end of the rotating plate 213 is rotatably connected to one end of the first connecting rod 214, one end of the second connecting rod 215, one end of the third connecting rod 216, and one end of the fourth connecting rod 217. The other ends of the first connecting rod 214, the second connecting rod 215, the third connecting rod 216, and the fourth connecting rod 217 are all connected to the transmission assembly 22.

[0044] The transmission assembly 22 includes a first swing plate 221, a second swing plate 222, a third swing plate 223, and a fourth swing plate 224. The lower end of the first swing plate 221 is rotatably connected to the other end of the first connecting rod 214, and the upper end of the first swing plate 221 is connected to the water volume regulating assembly 31.

[0047] Example 2: In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown in a preferred embodiment of this utility model, the water volume regulating component 31 includes a motor 311, a gear 312, a transmission gear ring 313, a rotating ring 314, a sliding plate 315, a mounting ring 316, a protrusion 318, and a connecting cylinder 319. The motor 311 is fixedly installed on the outer end of the connecting cylinder 319, and the output end of the motor 311 is fixedly connected to the gear 312. The rotating ring 314 is slidably connected to the inner wall of the connecting cylinder 319. A through groove is provided in the middle of the connecting cylinder 319, and the transmission gear ring 313 is fixedly connected to the rotating ring 314 through the through groove. The inner end of the transmission gear ring 313 slides against the outer end of the connecting cylinder 319. The gear 312 is meshed with the transmission gear ring 313. Multiple sliding plates 315 are provided, and the lower ends of the multiple sliding plates 315 are slidably connected to the rotating ring 314, and the upper ends of the multiple sliding plates 315 are slidably connected to the mounting ring 316. The lower ends of the multiple sliding plates 315 are fixedly installed with protrusions 318. The rotating ring 314 is provided with a sliding groove 317. Multiple sliding grooves 317 are provided at equal intervals with the protrusions 318 and are arranged in a circle. The sliding grooves 317 and the protrusions 318 are slidably connected. The mounting ring 316 is fixedly installed on the inner wall of the connecting cylinder 319. The lower end of the connecting cylinder 319 is connected to the rotating spray assembly 32.

[0048] The rotating spray assembly 32 includes a rotating cylinder 321, a conical block 322, and a nozzle 324. The lower end of the connecting cylinder 319 is slidably connected to the upper end of the rotating cylinder 321. The conical block 322 is fixedly installed at the inner bottom of the rotating cylinder 321. Multiple oblique grooves 323 are equally spaced on the outer surface of the conical block 322. Multiple nozzles 324 are equally spaced and fixedly installed at the outer end of the rotating cylinder 321.

[0049] The motor 311, gear 312, transmission gear ring 313, rotating ring 314, sliding plate 315, mounting ring 316, sliding groove 317, protrusion 318, connecting cylinder 319, rotating cylinder 321, conical block 322, and nozzle 324 are all provided in multiple quantities and are respectively arranged on the front and rear sides of the horizontal plate 11.

[0050] The first swing plate 221, the second swing plate 222, the third swing plate 223, and the fourth swing plate 224 are respectively fixedly connected to multiple connecting cylinders 319.

[0051] In use, water is pumped by a water pump (not shown in the figure) into the interior of the connecting cylinder 319. If the water flow needs to be adjusted, the motor 311 is started, which drives the gear 312 to rotate. The gear 312 drives the transmission gear ring 313 to rotate, which in turn drives the rotating ring 314 to rotate. The rotating ring 314 drives the sliding groove 317 to rotate, thereby causing the protrusion 318 to move in the sliding groove 317. The protrusion 318 drives the sliding plate 315 to slide on the mounting ring 316, thereby changing the opening and closing degree of the multiple sliding plates 315, thus changing the cross-sectional area of ​​the water flow channel. When the cross-sectional area of ​​the water flow channel is larger, the water volume is greater, and when the cross-sectional area of ​​the water flow channel is smaller, the water volume is less, thus achieving the adjustment of the water flow. Because the nozzle 324 is constantly oscillating, the water flow rate reaching different parts of the vehicle body is different, thus meeting the cleaning needs of different parts of the vehicle body and saving water resources.

[0052] When water flows out from between multiple sliding vanes 315 and impacts the conical block 322, the water flow generates tangential force under the action of multiple equidistant oblique grooves 323 on the outer surface of the conical block 322, which push the rotating cylinder 321 to rotate around its own axis. As the rotating cylinder 321 rotates, multiple nozzles 324 installed at the outer end of the rotating cylinder 321 also rotate, spraying water out in a rotating manner, expanding the spraying range and improving cleaning efficiency.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
