[0059] In order to make the objects, technical solutions and advantages of the present application clearer, the following will be combined with the accompanying drawings for the preferred embodiments of the present application to make the technical solutions in the embodiments of the present application more fully described. In the accompanying drawings, the same or similar notations represent the same or similar components or components with the same or similar functions throughout.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] In the description of the present application, it should be noted that unless specifically defined and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, it can be a fixed connection, or an indirect connection through an intermediate medium, or an internal communication of two elements or an interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0061] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0062] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0063] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0064] Currently, the cleaning equipment with wet mopping function usually comprises a main machine and a floor brush, the floor brush is provided with a dust suction port and a cleaning piece, the cleaning piece can comprise one or two of a mop, a roller brush and a disc brush, the main machine comprises a dust suction unit and a liquid supply unit, the dust suction unit generates negative pressure after being powered on, and the dust and sewage on the ground are sucked into the dust suction unit by the action of the negative pressure, at the same time, the liquid supply unit sprays clean water to the cleaning piece or the ground, and the cleaning piece continuously contacts the ground during the travel of the floor brush, so that the cleaning equipment completes wet mopping.

[0065] However, after the cleaning equipment cleans the ground, water stains are often left on the ground, and the cleaning effect of the cleaning equipment is not good. This is because after the cleaning piece stops cleaning, a certain amount of water remains on the cleaning piece, and since the cleaning piece always contacts the ground, the water remaining on the cleaning piece is easy to flow along the cleaning piece to the ground. For example, when a roller brush is used as the cleaning piece, since the axis of the roller brush is in the horizontal direction, the roller brush forms linear contact with the ground, and the place where the roller brush contacts the ground is easy to form a strip-shaped water stain. The water amount of the strip-shaped water stain is relatively large, the drying time is relatively long, and after drying, a relatively obvious water stain mark is left, thereby affecting the cleaning effect of the cleaning equipment.

[0066] In view of the above problems, the present application provides a floor brush and a cleaning equipment. The floor brush is connected to the base and the cleaning unit through the connecting unit, so that the cleaning unit is movably arranged on the base. When the cleaning unit stops cleaning, the elastic connecting piece drives the cleaning unit to move in the opposite direction of the travel direction of the floor brush through the guide piece, so as to wipe off the residual water stains, thereby improving the cleaning effect of the floor brush.

[0067] The technical solutions of the floor brush and the cleaning equipment provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0068] Referring to Figure 1 As shown in the drawings, the present application provides a cleaning equipment, which comprises a floor brush 100 and a cleaning equipment body 200, and the floor brush 100 is connected to the cleaning equipment body 200.

[0069] The floor brush 100 moves on the surface to be cleaned to wipe the surface to be cleaned, and the cleaning equipment body 200 is used to suck the dust and sewage on the surface to be cleaned and collect the dirt. The cleaning equipment can be a dust collector, a floor washing machine, etc.

[0070] In specific implementation, the cleaning equipment body 200 can comprise a main body 210 and a water tank assembly 220, the water tank assembly 220 is detachably arranged on the main body 210, the water tank assembly 220 is in communication with the cleaning unit 120, and the water tank assembly 220 is configured to provide cleaning liquid to the floor brush 100.

[0071] The main body 210 is configured to form a negative pressure to enable the cleaning device to suck dust and sewage on the surface to be cleaned under the action of the negative pressure, and the water tank assembly 220 is configured to provide cleaning liquid to the cleaning unit 120 of the floor brush 100 or the surface to be cleaned, so that the cleaning unit 120 absorbs moisture and then performs wet mopping on the surface to be cleaned. After the cleaning unit 120 stops cleaning, the cleaning unit 120 can move in the extension direction of the travel direction of the floor brush 100, so as to wipe the water stains left on the surface to be cleaned by the cleaning device, thereby improving the cleaning effect of the cleaning device.

[0072] Referring to Figures 1 to 3 As shown in the drawings, the floor brush 100 provided by the embodiment of the present application comprises a base 110, a cleaning unit 120, and a connecting unit 130. The cleaning unit 120 is configured to clean the surface to be cleaned. The connecting unit 130 comprises an elastic connecting piece 131 and a guide piece 132. The elastic connecting piece 131 is connected between the base 110 and the cleaning unit 120. The elastic force direction of the elastic connecting piece 131 is opposite to the travel direction of the cleaning unit 120.

[0073] The guide piece 132 is connected to the base 110, and the guide piece 132 defines a guide space extending along the travel direction of the floor brush 100, so that the cleaning unit 120 is movably arranged relative to the base 110 in the guide space.

[0074] In the embodiment, the base 110 is configured to mount the connecting unit 130 and support the cleaning unit 120, etc. At least part of the surface of the cleaning unit 120 protrudes outward from the base 110, so that at least part of the surface of the cleaning unit 120 is in contact with and rubs against the surface to be cleaned, thereby enabling the working surface of the cleaning unit 120 to wipe the surface to be cleaned. The connecting unit 130 is configured to connect the base 110 and the cleaning unit 120. The cleaning unit 120 can comprise a roller brush 1211, a disc brush, or a mop.

[0075] Specifically, the connecting unit 130 comprises the elastic connecting piece 131 and the guide piece 132. The elastic connecting piece 131 is configured to connect the guide piece 132 and the cleaning unit 120, or the elastic connecting piece 131 is configured to connect the base 110 and the cleaning unit 120, and is configured to provide the cleaning unit 120 with an elastic force opposite to the travel direction of the floor brush 100, so as to drive the cleaning unit 120 to move in the opposite direction of the travel direction of the floor brush 100. The guide piece 132 is configured to provide the cleaning unit 120 with a guiding action, so that the cleaning unit 120 moves in the extension direction of the travel direction of the floor brush 100 each time. The cleaning unit 120 can be arranged at the front end or the rear end of the travel direction of the floor brush 100.

[0076] For the convenience of description, the cleaning unit 120 is arranged at the front end of the travel direction of the floor brush 100 as an example. When the cleaning device is in standby, the resultant force acting on the cleaning unit 120 is zero, and the elastic connecting member 131 is in a reset state. When the cleaning device is started and the floor brush 100 performs cleaning work, because of the friction between the cleaning unit 120 and the surface to be cleaned, the friction is relatively large, the elastic force is relatively small, the resultant force direction points to the travel direction of the floor brush 100, and the elastic connecting member 131 is deformed, for example, the elastic connecting member 131 is elongated. The greater the deformation of the elastic connecting member 131, the greater the elastic force. When the elastic force increases to be equal to the friction, the elastic connecting member 131 no longer deforms. When the floor brush 100 stops wet mopping, the friction decreases or disappears, the resultant force direction points to the opposite direction of the travel direction of the floor brush 100, so as to drive the cleaning unit 120 to move toward the opposite direction of the travel direction of the floor brush 100, that is, the cleaning unit 120 retreats a distance under the action of the resultant force. In the process of retreating, the cleaning unit 120 contacts the surface to be cleaned with water stains, so as to flatten and partially absorb the water stains, thereby accelerating the evaporation of the water stains and reducing the residue of the water stains.

[0077] For example, when the cleaning unit 120 includes a roller brush 1211 and the elastic connecting member 131 is a tensile spring, during the cleaning work of the floor brush 100, the roller brush 1211 rotates around the horizontal axis relative to the surface to be cleaned and translates relative to the surface to be cleaned in the travel process of the floor brush 100. The friction of the surface to be cleaned on the roller brush 1211 points to the travel direction of the floor brush 100, the elastic force of the spring points to the opposite direction of the travel direction of the floor brush 100, and the friction is greater than the elastic force. Therefore, the spring is elongated. After the roller brush 1211 stops rotating, the friction decreases, and the spring resets due to the inertial effect of the spring, so as to make the roller brush 1211 translate relative to the surface to be cleaned in the opposite direction of the travel direction of the floor brush 100, thereby wiping off the strip-shaped water stains of the roller brush 1211 remaining on the surface to be cleaned.

[0078] The guide member 132 and the elastic connecting member 131 can be arranged side by side between the base 110 and the cleaning unit 120. The two ends of the extension direction of the guide member 132 are connected with the base 110 and the cleaning unit 120 respectively, and the two ends of the elastic force direction of the elastic connecting member 131 are connected with the base 110 and the cleaning unit 120 respectively. Alternatively, the guide member 132 and the elastic connecting member 131 can be arranged in sequence between the base 110 and the cleaning unit 120. The two ends of the elastic force direction of the elastic connecting member 131 are connected with the cleaning unit 120 and the guide member 132 respectively, and the two ends of the extension direction of the guide member 132 are connected with the elastic connecting member 131 and the base 110 respectively.

[0079] The floor brush 100 provided by the embodiment of the present application comprises a base 110, a cleaning unit 120 and a connecting unit 130, the connecting unit 130 comprises an elastic connecting piece 131 and a guide piece 132, the base 110 is arranged to mount and support the connecting unit 130 and the cleaning unit 120, the cleaning unit 120 is arranged to contact with a surface to be cleaned to wipe the surface to be cleaned, the guide piece 132 is arranged to provide a guiding effect for the cleaning unit 120 to enable the cleaning unit 120 to reciprocate relative to the base 110 along the extension direction of the guide piece 132, and the elastic connecting piece 131 is arranged to provide an elastic force for the cleaning unit 120 to enable the floor brush 100 to drive the cleaning unit 120 to move in the opposite direction of the moving direction of the floor brush 100 when the floor brush 100 stops cleaning, so as to wipe the water stains left on the surface to be cleaned by the cleaning unit 120 and avoid leaving water marks. Therefore, the floor brush 100 has a better cleaning effect.

[0080] In a possible implementation, the elastic force of the elastic connecting piece 131 and the friction force of the cleaning unit 120 when cleaning match with each other. In this way, when the cleaning unit 120 performs the cleaning work, the friction force can overcome the elastic force to enable the elastic connecting piece 131 to be elongated to a certain length, the cleaning unit 120 moves a distance in the direction of the friction force, and when the cleaning unit 120 stops the cleaning work, the elastic connecting piece 131 is reset under the action of the elastic force to drive the cleaning unit 120 to move in the direction of the elastic force, so as to wipe the residual water stains.

[0081] In some embodiments, the first end of the extension direction of the guide piece 132 is connected to the base 110, and the second end of the extension direction of the guide piece 132 faces the cleaning unit 120. In this way, the cleaning unit 120 can move back and forth relative to the base 110 along the extension direction of the guide piece 132.

[0082] Reference Figure 3 As shown in the specific implementation, the guide piece 132 has a guide cavity 1321 extending along the moving direction of the floor brush 100 to form a guide space. The end of the guide cavity 1321 facing the cleaning unit 120 has an opening, and at least part of the structure of the cleaning unit 120 extends into the guide cavity 1321 through the opening.

[0083] In this way, the cleaning unit 120 can extend into the guide cavity 1321 through the opening, or part of the cleaning unit 120 can be separated from the guide cavity 1321 through the opening, the cleaning unit 120 can form a moving connection relationship with the base 110 through the guide piece 132, so that the cleaning unit 120 can move along the moving direction of the floor brush 100, or the cleaning unit 120 can move in the opposite direction of the moving direction of the floor brush 100.

[0084] In a possible implementation, the elastic connecting member 131 is arranged in the guide cavity 1321.

[0085] In this way, the elastic connecting member 131 can be hidden in the guide cavity 1321, so that foreign matter cannot enter the guide cavity 1321 to cause the elastic connecting member 131 to be stuck. In addition, the elastic force direction of the elastic connecting member 131 is consistent with the extension direction of the guide cavity 1321, so that the elastic connecting member 131 can provide an elastic force for the cleaning unit 120 to drive the cleaning unit 120 to retreat along the extension direction of the guide cavity 1321 to wipe the remaining water stains.

[0086] Referring to Figure 3 In a specific implementation, the cleaning unit 120 includes a cleaning member 121 and a connecting arm 122, the cleaning member 121 is connected to a first end of the connecting arm 122, an elastic member is connected between a second end of the connecting arm 122 and the base 110, and the connecting arm 122 is movably arranged in a guide space defined by the guide member 132.

[0087] In this way, at least part of the surface of the cleaning member 121 protrudes out of the base 110 to contact and rub against the surface to be cleaned, so as to wipe the surface to be cleaned. The cleaning member 121 can be connected to the elastic connecting member 131 through the connecting arm 122, the elastic force acts on the cleaning member 121 through the connecting arm 122, and the frictional force of the surface to be cleaned on the cleaning unit 120 is applied to the cleaning member 121. The elastic force and the frictional force are both parallel to the surface to be cleaned, so that the cleaning member 121 moves relative to the base 110 under the combined action of the elastic force and the frictional force.

[0088] In a possible implementation, the connecting arm 122 extends along the advancing direction of the floor brush 100.

[0089] In this way, the extension direction of the connecting arm 122 is in the same straight line as the elastic force direction of the elastic connecting member 131, so that the resultant force direction of the connecting arm 122 is always along the advancing direction of the floor brush 100 or along the opposite direction of the advancing direction of the floor brush 100, thereby avoiding the connecting arm 122 driving the cleaning member 121 to move along a direction perpendicular to the advancing direction of the floor brush 100, that is, the cleaning member 121 can be prevented from moving left and right while advancing or retreating.

[0090] In order to improve the connection stability and movement stability, the number of the connecting arms 122 is two, and the two connecting arms 122 are arranged at opposite ends of the cleaning member 121 respectively.

[0091] In this way, the connecting arms 122 can be symmetrically arranged relative to the cleaning member 121, so that the connecting arms 122 stably drive the cleaning member 121 to move along the advancing direction of the floor brush 100 or along the opposite direction of the advancing direction of the floor brush 100, thereby avoiding the cleaning member 121 swinging left and right relative to the central axis of the floor brush 100 when moving.

[0092] In order to improve the guiding stability, in a possible implementation, the guide 132 is two, and the two guides 132 and the connecting arm 122 are arranged in one-to-one correspondence. In this way, the connecting arm 122 at the opposite ends of the cleaning element 121 can be guided by the corresponding guide 132, so that the connecting arm 122 always moves along the travel direction of the floor brush 100 or in the opposite direction of the travel direction of the floor brush 100, thereby ensuring the consistency of the moving direction of the cleaning element 121.

[0093] In some embodiments, the connecting arm 122 and the guide 132 are relatively slidably arranged along the travel direction of the floor brush 100. In this way, the connecting arm 122 and the guide 132 can be slidably arranged, so that the connecting arm 122 can slide back and forth relative to the guide 132, thereby making the connecting arm 122 move back and forth along the extension direction of the guide 132.

[0094] In a specific implementation, one of the connecting arm 122 and the guide 132 has a sliding groove, and the other has a sliding rail, which is arranged in the sliding groove and slidably arranged along the sliding groove.

[0095] For example, a sliding groove can be arranged on the cavity wall of the guide cavity 1321, and a sliding rail can be arranged on the side wall of the connecting arm 122, or a sliding rail can be arranged on the cavity wall of the guide cavity 1321, and a sliding groove can be arranged on the side wall of the connecting arm 122. By slidably arranging the sliding rail and the sliding groove, the connecting arm 122 can reciprocate relative to the guide 132 along the extension direction of the sliding rail and the sliding groove, thereby making the cleaning unit 120 always move back and forth in the same direction to prevent the moving direction of the cleaning unit 120 from deviating.

[0096] In some embodiments, the connecting arm 122 and the cleaning element 121 can be rotatably arranged. Compared with the cleaning element 121 that can only translate relative to the surface to be cleaned, the cleaning element 121 that can both translate and rotate relative to the surface to be cleaned has better cleaning effect.

[0097] For example, the cleaning element 121 can be a disc brush, and the axial direction of the disc brush is arranged in the vertical direction. By rotatably arranging the connecting arm 122 and the disc brush, the disc brush can rotate rapidly around the vertical axis relative to the ground during the travel of the floor brush 100, so that the disc brush can rotate relative to the base 110 to efficiently remove stains on the ground.

[0098] In a possible implementation, the cleaning element 121 is a roller brush 1211, and the axial direction of the roller brush 1211 is arranged in the horizontal direction.

[0099] In this way, the rolling brush 1211 can rotate around its own axis, so that the surface of the rolling brush 1211 is in turn in contact with the surface to be cleaned when the rolling brush 1211 rotates, so as to wipe off the stains on the surface to be cleaned, and the rolling brush 1211 can roll up the dirt such as hair on the surface to be cleaned and suck it into the main body 210 under the action of negative pressure when wiping.

[0100] In some embodiments, the ground brush 100 further comprises a driving motor fixedly connected to the base 110 and a flexible transmission member arranged between the driving shaft of the driving motor and the rolling brush 1211. In this way, when the cleaning device is working, the driving motor can transmit power to the rolling brush 1211 through the flexible transmission member to drive the rolling brush 1211 to rotate around its own axis, so as to generate a larger friction force with the surface to be cleaned to drive the rolling brush 1211 to move along the direction of travel of the rolling brush 1211 against the elastic force.

[0101] The flexible transmission member can be a belt or a chain.

[0102] Referring to Figure 2 In a possible implementation, the ground brush 100 provided by the embodiments of the present application further comprises a water spraying member 140 and a water scraping member 150, both of which are arranged on the base 110, and the nozzle of the water spraying member 140 faces the cleaning member 121, and the water scraping member 150 extends in the same direction as the rolling brush 1211.

[0103] In this way, the water spraying member 140 can uniformly spray cleaning liquid to the rolling brush 1211 to keep the rolling brush 1211 in a wet state, and the water scraping member 150 can scrape off the dirt and excess water on the surface of the rolling brush 1211 after the rolling brush 1211 wipes the surface to be cleaned and suck it into the ground brush 100, so as to prevent the dirty water from flowing to the surface that has been cleaned and polluting the surface that has been cleaned.

[0104] It can be understood that when the instruction to stop cleaning is received, the water tank assembly 220 will reduce or stop supplying water to the water spraying member 140, and control the main body 210 to continue to suck dust from the surface to be cleaned to suck the remaining water stains on the surface to be cleaned. At the same time, the elastic connecting member 131 drives the cleaning member 121 to wipe the surface to be cleaned to jointly reduce the liquid residue on the surface to be cleaned.

[0105] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
