DETAILED DESCRIPTION

[0027] The embodiments of the present utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present utility model are described in detail below.

[0028] The embodiments of the present utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present utility model are described in detail below. Figures 1-4 The embodiments of the present utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present utility model are described in detail below.

[0029] The embodiments of the present utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present utility model are described in detail below. Figures 1-4 The embodiments of the present utility model are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present utility model are described in detail below.

[0030] The lifting mechanism and the scraping strip 10 are in transmission connection, the mode switching mechanism 30 is connected with the scraping strip 10, and the mode switching mechanism 30 is configured to make the scraping strip 10 have a fixed state and a lifting state, wherein in the fixed state, the scraping strip 10 keeps away from the surface to be cleaned, and in the lifting state, the scraping strip 10 contacts or keeps away from the surface to be cleaned under the driving of the lifting mechanism.

[0031] Specifically, the squeegee 10 control structure is arranged inside the shell of the cleaning device, the lifting mechanism can drive the squeegee 10 to move in the direction intersecting with the surface to be cleaned, and the mode switching mechanism 30 switches the squeegee 10 between the fixed state and the lifting state. In the fixed state, the squeegee 10 is stably away from the surface to be cleaned and cannot be moved, which facilitates the maintenance and inspection of the cleaning device or makes the cleaning device avoid obstacles on the surface to be cleaned. In the lifting state, the squeegee 10 can be flexibly lifted to meet the cleaning requirements of complex scenes.

[0032] In one example, the lifting mechanism can be two swing wheels 21, which are arranged at intervals in the length direction of the squeegee 10 to drive the squeegee 10 to rise or fall. The shell can be provided with a notch at a position corresponding to the swing wheel 21, so that the swing wheel 21 has sufficient swing space in the front-back direction.

[0033] Further, referring to Figures 2-3 The mode switching mechanism 30 includes a first transmission member 35 and a bottom plate 34, the first transmission member 35 is connected to the bottom plate 34, and the first transmission member 35 is configured to switch between the first position and the second position relative to the bottom plate 34 when subjected to force. In the first position, the first transmission member 35 is away from the surface to be cleaned. In the second position, the first transmission member 35 is close to the surface to be cleaned. In this way, the mode switching mechanism 30 switches the first transmission member 35 between the first position and the second position, and since the first transmission member 35 and the squeegee 10 are connected to each other, the squeegee 10 is switched along with the first transmission member 35. That is, when the first transmission member 35 is in the first position, the squeegee 10 is in the fixed state, that is, the squeegee 10 is stably away from the surface to be cleaned and cannot be moved, which facilitates the maintenance and inspection of the cleaning device or makes the cleaning device avoid obstacles on the surface to be cleaned. When the first transmission member 35 is in the second position, the squeegee 10 is in the lifting state, that is, the squeegee 10 can be flexibly lifted to meet the cleaning requirements of complex scenes.

[0034] Therefore, the mode switching mechanism 30 switches the squeegee 10 between the fixed state and the lifting state, and the squeegee 10 can be fixed away from the surface to be cleaned or can be flexibly lifted, which can conveniently switch the working state of the squeegee 10 according to actual needs, and improves the flexibility and adaptability of the cleaning device.

[0035] Referring to Figures 3-4 The mode switching mechanism 30 further includes a connecting rod 36, the connecting rod 36 penetrates the bottom plate 34, and the two ends of the connecting rod 36 are connected to the first transmission member 35, and the connecting rod 36 drives the first transmission member 35 to move between the first position and the second position. Specifically, the inner side of the first transmission member 35 is provided with two through holes 352, the two through holes 352 are arranged at intervals in the length direction of the first transmission member 35, and the two ends of the connecting rod 36 are connected to the through holes 352 after penetrating the bottom plate 34, so that the first transmission member 35 and the connecting rod 36 can move synchronously.

[0036] Thus, when an external force is applied to the first transmission member 35, the first transmission member 35 is adjusted between the first position and the second position. For example, when a downward pressure is applied to the first transmission member 35, the first transmission member 35 is moved from the first position to the second position, and under the limited cooperation of the connecting rod 36, the first transmission member 35 is stopped at the second position. For another example, when an upward pressure is applied to the first transmission member 35, the first transmission member 35 is moved from the second position to the first position, and under the limited cooperation of the connecting rod 36, the first transmission member 35 is stopped at the first position.

[0037] Referring to Figure 4 The connecting rod 36 includes a first rotating portion 361, a connecting portion 362, and a second rotating portion 363. The connecting portion 362 is connected between the first rotating portion 361 and the second rotating portion 363 and is arranged perpendicularly relative to the first rotating portion 361 and the second rotating portion 363. The first rotating portion 361 penetrates the bottom plate 34, and the second rotating portion 363 cooperates with the first transmission member 35. In this way, the first rotating portion 361 is fixed in the floor and can rotate, and the second rotating portion 363 and the connecting portion 362 can rotate therewith, so that the second rotating portion 363 changes position in the up-down direction.

[0038] Referring to Figure 4 The connecting rod 36 is at least two, and the at least two connecting rods 36 are arranged in the up-down direction. By arranging at least two connecting rods 36, better balance can be provided, and the swing or instability phenomenon that may occur in a single connecting rod 36 is reduced. The double connecting rod 36 design disperses the load, increases the synchronization of the movement of the first transmission member 35 and the connecting rod 36, and improves the reliability of the mode switching mechanism 30.

[0039] The first transmission member 35 is further provided with an operating rod 38 to apply force to the first transmission member 35 through the operating rod 38.

[0045] In addition, the elastic part 37 can be at least two, and the at least two elastic parts 37 are spaced in the length direction of the first transmission part 35. Similarly, the first matching part 341 and the second matching part 351 are at least two groups. In this way, by arranging at least two elastic parts 37, the first transmission part 35 is more stable when adjusting between the first position and the second position, and the damping force when adjusting is more appropriate.

[0046] In addition, the elastic part 37 can be at least two, and the at least two elastic parts 37 are spaced in the length direction of the first transmission part 35. Similarly, the first matching part 341 and the second matching part 351 are at least two groups. In this way, by arranging at least two elastic parts 37, the first transmission part 35 is more stable when adjusting between the first position and the second position, and the damping force when adjusting is more appropriate. Figures 2-4 As shown in the figure, the upper end of the bottom plate 34 is provided with a sealing flange, the upper end of the first transmission part 35 and the side facing the bottom plate 34 are provided with a avoiding slot, and the avoiding slot and the sealing flange are matched when the first transmission part 35 is in the first position. That is, the sealing flange is arranged on the bottom plate 34, and the avoiding slot which can be matched with the sealing flange is arranged on the first transmission part 35. In this way, when the first transmission part 35 is in the first position, the avoiding slot and the sealing flange are matched, so as to improve the integrity of the wiper control structure, and prevent dust from entering between the first transmission part 25 and the bottom plate 34 in the first position.

[0047] The first transmission part 35 is provided with a second clamping part, and the first clamping part and the second clamping part are clamped and matched with each other, so as to realize the mutual connection between the wiper 10 and the first transmission part 35.
