[0095] It should be noted that the specific installation position of the inner support 100A is not limited herein. The inner support 100A can be installed in the second rod 400, or the inner support 100A can be installed in the first rod 100. Of course, the inner support 100A can also be arranged across the second rod 400 and the first rod 100, that is, a part of the inner support 100A is arranged in the second rod 400, and the other part of the inner support 100A is arranged in the first rod 100. It should be further noted that the specific number of the inner support 100A is not limited herein. The inner support 100A can be arranged in at least two. At least one inner support 100A can be arranged in the first rod 100 and the second rod 400 respectively.

[0096] Further, taking the inner support 100A arranged in the first rod 100 as an example, the inner support 100A should be adapted to the shape of the hollow inside of the first rod 100, so that the inner support 100A arranged in the first rod 100 will not slide or fall off when the cleaning device is working. The inner support 100A arranged in the first rod 100 can realize integrated installation of the water channel, the circuit line and the power supply in the rod assembly as a bearing and connecting unit of the internal components of the rod assembly (which will be described in detail later). Since the first rod 100 is hollow inside, the inner support 100A arranged in the first rod 100 supports the inner wall of the first rod 100 to increase the structural strength and rigidity of the first rod 100, thereby further increasing the rigidity of the rod assembly while reducing the overall weight of the rod assembly.

[0097] In one embodiment, referring to Figure 9 , Figure 2 andFigure 3 The rod assembly further comprises a water pump 101 arranged on the inner support 100A, and a water inlet pipe (not shown in the figure) and a water outlet pipe (not shown in the figure) arranged on the hinge rod 20. The water pump 101 is arranged close to the lower port 100A1 of the inner support 100A. The water pump 101 is provided with a water outlet 101a and a water inlet 101b, both of which are arranged towards the direction of the hinge rod 20. The water outlet 101a and the water inlet 101b are connected to the water outlet pipe and the water inlet pipe respectively through the lower port 100A1, and the water inlet pipe and the water outlet pipe are connected to the trailing head 30, thereby forming a water channel connecting the rod assembly and the trailing head 30.
