The cleaning robot is generally provided with a drum, and cleans a surface to be cleaned by applying clean water to the drum and then using the wetted drum. In order to avoid secondary pollution of the sewage on the drum to the surface to be cleaned, a sewage tank and a sewage scraping plate are usually arranged near the drum for recycling the sewage.

However, after the roller of the cleaning robot is used for a long time, the roller is contacted with an external object, materials on the roller can be gradually worn, the outer surface layer of the roller is gradually thinned, at the moment, the roller cannot be fully attached to the dirt scraping plate, even the dirt scraping plate cannot play a role, and the collection of sewage from the sewage tank to the roller is affected.

In addition, the contact mode of dirt scraping plate and cylinder periphery is hard contact, and in the cylinder execution cleaning function in-process, dirt scraping plate also causes wearing and tearing to the periphery of cylinder easily, and dirt scraping plate and cylinder's life all receive the influence.

In addition, the existing cleaning robot needs users to pour sewage after the sewage tank is filled, and the accommodating space of the existing sewage tank is limited and has smaller capacity, so that the use experience of the users is reduced.

As shown in fig. 4, in order to solve the above-mentioned technical problem, in a first aspect, an embodiment of the present application provides a floor cleaning device 100, which is mainly applied to a cleaning robot 1000 for cleaning a surface to be cleaned.

As shown in fig. 2 and 4, a cartesian coordinate system is established defining that the width direction of the waste water recovery tank 140 is parallel to the first direction, the height direction of the waste water recovery tank 140 is parallel to the second direction, and both the length direction of the waste water recovery tank 140 and the axial direction of the drum 111 are parallel to the third direction. It is to be understood that the above definitions are merely provided to facilitate understanding of the relative positional relationship of the various parts of the floor cleaning device 100 and are not to be construed as limiting the present application.

As shown in fig. 4, 5 and 9, the floor cleaning device 100 includes: a drum assembly 110, a sewage collection tank 120, and an adjustment assembly 130.

The roller assembly 110 includes a bracket 112 and a roller 111 rotatably disposed on the bracket 112, and the bracket 112 is provided with a limiting hole 1121. The sewage collection tank 120 is slidably connected to the bracket 112 along the first direction, and a sewage scraping portion 122 is disposed on a side of the sewage collection tank 120 facing the drum 111, the sewage scraping portion 122 abuts against the outer periphery of the drum 111, and the sewage collection tank 120 defines a mounting position 123. The adjustment assembly 130 includes: the sewage collecting box comprises an elastic driving piece 132 which is connected with the inner wall of the installation position 123 of the sewage collecting box 120 in a sliding way along a first direction, and an elastic clamping piece 131 which is connected with the elastic driving piece 132 in a sliding way along a second direction, wherein the first direction is perpendicular to the second direction.

As shown in fig. 6 and 7, when the elastic clamping member 131 is pressed, the elastic clamping member 131 is clamped into the limiting hole 1121, so that the sewage collecting tank 120 is driven to move in a direction approaching the drum 111 by the elastic driving member 132, and the sewage scraping portion 122 is brought into contact with the outer circumference of the drum 111.

It can be appreciated that, in the floor cleaning apparatus 100 provided in this embodiment, when the elastic clamping member 131 is pressed, the elastic clamping member 131 can be clamped into the limiting hole 1121 of the bracket 112, so that the elastic driving member 132 drives the sewage collecting box 120 to move along the direction close to the roller 111, that is, along the first direction close to the roller 111, so that the dirt scraping portion 122 contacts with the periphery of the roller 111, and the dirt scraping portion 122 is fully attached to the periphery of the roller 111, so that the dirt scraping portion 122 can continue to function, and the service life is prolonged.

Illustratively, the dirt scraper 122 may be an edge of the dirt inlet 121 of the dirt collection tank 120 or a dirt scraper plate secured to the dirt collection tank 120.

As shown in fig. 7 and 8, when the drum 111 rotates about its axis and the scraping portion 122 contacts the outer circumference of the drum 111, the scraping portion 122 can scrape off the garbage and sewage on the drum 111 and introduce the same into the sewage collection tank 120, thereby improving the collection efficiency of the sewage collection tank 120 for sewage.

It can be appreciated that, because the elastic driving member 132 has elastic capability, when the elastic clamping member 131 is clamped into the limiting hole 1121, the dirt scraping portion 122 on the sewage collecting box 120 can be elastically attached to the periphery of the drum 111, so that the dirt scraping portion 122 dynamically floats in the first direction, thereby alleviating the hard contact phenomenon between the dirt scraping portion 122 and the periphery of the drum 111, and prolonging the service lives of the dirt scraping portion 122 and the drum 111.

Because the elastic clamping piece 131 has elastic capability, when a user presses the elastic clamping piece 131 manually or through an actuating mechanism, the elastic clamping piece 131 can be automatically clamped into the limiting hole 1121 under the action of elastic force, so that the user can conveniently adjust the fit degree of the dirt scraping part 122 and the roller 111, and the adjustment efficiency of the adjustment assembly 130 is improved.

In addition, the limiting hole 1121 may be a through hole, that is, the limiting hole 1121 penetrates through the bracket 112, so that the elastic clamping member 131 can be fully clamped into the limiting hole 1121, and the structural stability of the elastic clamping member and the bracket after clamping is improved.

As shown in fig. 13, in one embodiment, the elastic clamping member 131 includes a fastening member 1311 and a first elastic member 1312, the elastic driving member 132 is provided with a receiving groove 13211, the fastening member 1311 is slidably connected with a groove wall of the receiving groove 13211, and the first elastic member 1312 is coupled between the fastening member 1311 and a groove wall of a side of the receiving groove 13211 away from the fastening member 1311.

It can be appreciated that, when the fastening member 1311 is pressed, the fastening member 1311 drives the elastic driving member 132 to approach the roller 111 along the first direction, and when the elastic driving member 132 moves to the preset position, the fastening member 1311 can be fastened into the limiting hole 1121 of the bracket 112 under the pushing of the elastic force of the first elastic member 1312, and at this time, the dirt scraping portion 122 contacts the periphery of the roller 111 more fully and the fitting is tighter.

Illustratively, the first resilient member 1312 is a cylindrical spring or leaf spring. When the first elastic member 1312 adopts a cylindrical spring, the fastening member 1311 may have an assembly hole along the second direction for accommodating at least a portion of the cylindrical spring, and an end of the cylindrical spring away from the assembly hole abuts against a groove wall of the accommodating groove 13211 on a side away from the fastening member 1311.

Thus, through the arrangement of the assembly holes, an accommodating space is provided, so that the buckling piece 1311 can accommodate the cylindrical spring, thereby improving the structural compactness of the first elastic piece 1312 and being beneficial to the miniaturization design of the adjusting assembly 130.

As shown in fig. 14, further, a positioning post 13213 is disposed on a side of the receiving groove 13211 away from the fastening piece 1311, and one end of the cylindrical spring is inserted into the positioning post 13213, so as to facilitate assembly of the cylindrical spring, thereby improving assembly efficiency of the elastic fastening member 131.

It should be noted that, the first elastic member 1312 is coupled between the fastening member 1311 and a groove wall of the receiving groove 13211 on a side away from the fastening member 1311, that is, the two ends of the first elastic member 1312 may abut between the fastening member 1311 and the groove wall of the receiving groove 13211, or may be fixed between the fastening member 1311 and the groove wall of the receiving groove 13211, and both the two connecting manners may enable the fastening member 1311 to elastically slide in the second direction.

In another embodiment, the elastic clamping member 131 is a buckle made of an elastic material, and the buckle of this embodiment can also be clamped into the limiting hole 1121 of the bracket 112 when the elastic driving member 132 moves a predetermined distance.

As shown in fig. 13, in one embodiment, the elastic driving member 132 includes a sliding seat 1321 and a second elastic member 1322, where the sliding seat 1321 is slidably connected to an inner wall of the mounting location 123, and the second elastic member 1322 is coupled between the sliding seat 1321 and a groove wall of a side of the mounting location 123 near the drum 111.

It will be appreciated that the sliding seat 1321 is slidably coupled to the inner wall of the mounting location 123 such that the sliding seat 1321 is capable of sliding in a first direction within the mounting location 123 relative to the waste collection tank 120. The second elastic member 1322 is one of the components of the elastic portion of the elastic driving member 132, and is coupled between the sliding seat 1321 and the groove wall of the installation site 123 on the side close to the drum 111, so that the sliding seat 1321 can elastically float in the first direction with respect to the sewage collecting tank 120 within the installation site 123.

In this way, when the elastic clamping member 131 drives the sliding seat 1321 to move, the second elastic member 1322 pushes the sewage collecting tank 120 to approach the drum 111 along the first direction, so that the dirt scraping portion 122 is fully attached to the periphery of the drum 111.

In this embodiment, the second elastic member 1322 may be a cylindrical spring or a shrapnel, similar to the first elastic member 1312.

As shown in fig. 9 and 13, the second elastic member 1322 is illustratively a cylindrical spring, the sliding seat 1321 and the mounting location 123 are respectively provided with a positioning portion 12312 on the groove wall on one side of the roller 111, and two ends of the cylindrical spring are respectively inserted between the two positioning portions 12312, so as to facilitate assembly of the cylindrical spring, thereby improving assembly efficiency of the elastic driving member 132.

In another embodiment, the elastic driving member 132 is a push block made of an elastic material, such as silicone, rubber, etc. The push block made of an elastic material can apply a force to the sewage collection tank 120 in an elastic manner as well, and can be used instead of the second elastic member 1322 and the sliding seat 1321.

As shown in fig. 11 and 12, in one embodiment, in order to improve stability and smoothness when the sewage collection tank 120 slides with respect to the bracket 112, sliding portions 124 are formed at opposite sides of the sewage collection tank 120 in a third direction, and guide portions 1122 are formed on the bracket 112 to be engaged with the sliding portions 124, the sliding portions 124 are slidably connected with the guide portions 1122, and the third direction is perpendicular to the first and second directions, respectively.

Illustratively, the sliding portion 124 is an extension plate integrally formed on the sewage collection tank 120, and the guide portion 1122 is a chute.

When pressing the elastic clamping piece 131, the elastic driving piece 132 can drive the sewage collecting box 120 to move along the direction close to the roller 111, the extending plate slides along the groove wall of the chute in the moving process, the chute not only can play a guiding role on the extending plate, the moving stability of the sewage collecting box 120 is improved, but also the sliding smoothness of the sewage collecting box 120 can be improved.

Of course, for the above example, the sliding portion 124 may also be a sliding groove, and the guiding portion 1122 may be a guiding rib integrally formed on the bracket 112, so that the sliding groove can slide along the guiding rib during the movement of the sewage collecting tank 120, and the stability and fluency of the sewage collecting tank 120 sliding relative to the bracket 112 may be improved.

As shown in fig. 11 and 12, the sliding portion 124 may be disposed at a position of the sewage collection tank 120 close to the mounting position 123 thereof, and the guiding portion 1122 is disposed at a position of the support 112 corresponding to the sliding portion 124, so that stability and smoothness of the sliding of the sewage collection tank 120 with respect to the support 112 can be further improved.

As shown in fig. 9, in one embodiment, the elastic driving member 132 is provided with a stop portion 13212 at opposite sides thereof along a third direction, a limiting portion 12311 is formed at a side of the mounting portion 123 away from the drum 111, and the limiting portion 12311 can abut against the stop portion 13212 to limit the elastic driving member 132 from sliding out of the mounting portion 123 along a direction away from the drum 111, and the third direction is perpendicular to the first direction and the second direction, respectively.

It can be appreciated that, due to the provision of the stop portion 13212 and the limiting portion 12311, when the elastic driving member 132 moves to a preset distance along the direction away from the drum 111, the limiting portion 12311 abuts against the stop portion 13212, so as to limit the elastic driving member 132 from sliding out of the mounting position 123 along the direction away from the drum 111, so that the elastic driving member 132 can be prevented from being separated from the mounting position 123, the stability of the assembly structure of the elastic driving member 132 and the sewage collecting tank 120 is improved, and the service life is prolonged.

For example, the stop portion 13212 may be a buckle, and the limiting portion 12311 is a baffle integrally formed on an inner wall of the mounting location 123, and the baffle can abut against the buckle to prevent the elastic driving member 132 from being separated from the mounting location 123.

In one embodiment, in order to facilitate adjusting the fit degree of the dirt scraping portion 122 and the drum 111, a plurality of limiting holes 1121 are formed, and the plurality of limiting holes 1121 are arranged at intervals along the first direction, and the elastic clamping member 131 can slide out of one limiting hole 1121 and be clamped into the adjacent other limiting hole 1121.

It will be appreciated that by arranging the plurality of limiting holes 1121 at intervals along the first direction, the elastic clamping member 131 can slide out of one limiting hole 1121 and be clamped into the adjacent other limiting hole 1121.
