[0028] As shown in Figures 1-3 A water rake swing mechanism for a floor cleaning machine includes a fixed seat 3, a positioning rod 1, a water rake connecting plate 2 and a driving assembly.

[0029] The fixed seat 3 is fixed to the main body of the floor cleaning machine upwardly, as shown in Figure 1 The fixed seat 3 is a frame structure, and the positioning rod 1 is fixed on the bottom surface of the fixed seat 3. Specifically, the positioning rod 1 includes a bolt and a nut matched with the bolt. The end of the bolt penetrates the fixed seat 3 and is screwed with the fixed seat. The end of the bolt extends out of the fixed seat 3 and is screwed with the nut. In this way, the positioning rod 1 forms a middle thin section and two end boss parts.

[0030] As shown in Figure 1 and 2 The thin section penetrates the first end of the water rake connecting plate 2 and is gap matched with the water rake connecting plate 2. Specifically, the through hole for the thin section to penetrate on the water rake connecting plate 2 is a long hole 21 extending front and back. In this way, the water rake connecting plate 2 can move up and down, front and back, and left and right on the bolt, and has good flexibility, can be used in various ground conditions, and has simple structure, small action range, is beneficial to save space, and has good use experience.

[0031] The second end of the water rake connecting plate 2 is away from the brush disc and is fixed with a water rake, which is a prior art and is used for sucking away the cleaned sewage from the ground, and will not be described here again. The fixing seat 3, the positioning rod 1, the water rake connecting plate 2 and the water rake are symmetrically arranged about the central axis of the scrubber, so that the overall structure of the scrubber has good stability.

[0032] As shown in Figure 1 The bottom of the fixing seat 3 is provided with two groups of front and rear first wheels to support the fixing seat 3 and the water rake swing mechanism, so as to facilitate the movement of the scrubber. The bottom of the water rake is provided with a group of second wheels to support the water rake and facilitate the overall movement of the scrubber.

[0033] The driving assembly is used for driving the water rake connecting plate 2 to swing up and down, so that the water rake contacts or separates from the ground, so as to realize the switching between the working state and the non-working state. In the embodiment, the driving assembly includes a pneumatic support rod 4 and a pull rod 5. The pneumatic support rod 4 is a prior art, and a person skilled in the art can select it according to the needs. Here, it will not be described again, which is used to maintain the position state of the water rake connecting plate 2. As shown in Figure 1 and 3 The first end of the pneumatic support rod 4 is spherically hinged to the top surface of the fixing seat 3, and the second end of the pneumatic support rod 4 is spherically hinged near the second end of the water rake connecting plate 2. The pull rod 5 is hinged downward to the water rake connecting plate 2. Specifically, the hinge between the pull rod 5 and the water rake connecting plate 2 is located outside the second end of the pneumatic support rod 4, so that a larger swing moment can be obtained. The upper part of the pull rod 5 is vertically fixed with a handle, and the operator holds the handle to operate the pull rod. In this way, the water rake connecting plate 2 can be driven to swing up and down with the water rake, so that the water rake contacts or separates from the ground, so as to realize the switching between the working state and the non-working state. Under the action of the pneumatic support rod 4, the water rake can be maintained in the working state or the non-working state.

[0034] As shown in Figure 1 The pneumatic support rod 4 and the pull rod 5 are symmetrically arranged about the central axis of the scrubber.
