Description

Technical Field

[0001] The present application relates to the technical field of surface cleaning, and in particular to a surface cleaning device. Background Art

[0002] Surface cleaning equipment is mainly used to clean and maintain hard surfaces such as floors, tiles, marble, etc. Floor scrubbers are common surface cleaning equipment on the market. They can mop the floor and suck out the water stains left on the floor after mopping to prevent the floor from being too slippery. The sucked-out sewage will be stored in the sewage tank. After the cleaning work is completed, the water in the sewage tank will be centrally processed.

[0003] In the related art, the surface cleaning equipment usually includes a body, a handle, a floor brush assembly, a clean water tank, a dirty water tank and a suction source. The handle is installed at the upper end of the body, the floor brush assembly is installed at the lower end of the body, and the clean water tank, the dirty water tank and the suction source are installed on the body. When the roller brush of the floor brush assembly rotates, the clean water in the clean water tank flows out from the roller brush to remove stains, oil stains and other dirt on the surface to be cleaned while washing and brushing. In this process, the suction source is used to suck the dirty water remaining after the roller brush is cleaned into the dirty water tank to keep the surface to be clean and tidy.

[0004] Since both the clean water tank and the sewage tank are installed on the machine body, and in order to facilitate user operation, the volume of the sewage tank is usually small, so that the sewage tank is easily filled with water. The sewage tank needs to be emptied frequently to prevent the sewage in the sewage tank from being sucked into the suction source from the suction port. Especially when the machine body is in a state parallel to the ground, the sewage tank needs a larger water storage space to prevent the sewage in the sewage tank from flowing horizontally to the suction port and being sucked into the suction source.

In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0039] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0040] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0041] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0044] The present application provides a surface cleaning device for cleaning hard surfaces such as floors, tiles, marble, etc., and for sucking out water stains remaining on the floor after mopping to prevent the floor from being too slippery. It is understandable that the surface cleaning device can be a floor scrubber, such as a portable floor scrubber or a ride-on floor scrubber, etc., which is not limited here.

[0045] In the related art, the surface cleaning equipment usually includes a body, a handle, a floor brush assembly, a clean water tank, a dirty water tank and a suction source. The handle is installed at the upper end of the body, the floor brush assembly is installed at the lower end of the body, and the clean water tank, the dirty water tank and the suction source are installed on the body. When the roller brush of the floor brush assembly rotates, the clean water in the clean water tank flows out from the roller brush to remove stains, oil stains and other dirt on the surface to be cleaned while washing and brushing. In this process, the suction source is used to suck the dirty water remaining after the roller brush is cleaned into the dirty water tank to keep the surface to be clean and tidy.

[0046] Since both the clean water tank and the sewage tank are installed on the machine body, and in order to facilitate user operation, the volume of the sewage tank is usually small, so that the sewage tank is easily filled with water. The sewage tank needs to be emptied frequently to prevent the sewage in the sewage tank from being sucked into the suction source from the suction port. Especially when the machine body is in a state parallel to the ground, the sewage tank needs a larger water storage space to prevent the sewage in the sewage tank from flowing horizontally to the suction port and being sucked into the suction source.

[0047] In order to solve the above problems, the surface cleaning equipment provided in the present application installs a clean water tank on the floor brush assembly and a dirty water tank on the body. Compared with the technical solution in which both the clean water tank and the dirty water tank are installed on the body, this solution only installs the dirty water tank on the body, which can increase the volume of the dirty water tank to avoid the dirty water in the dirty water tank being sucked into the suction source.

[0048] Figure 1 A schematic structural diagram of the surface cleaning device provided by the present application is shown. Figure 2 A cross-sectional schematic diagram of a surface cleaning device provided by the present application is shown. Figure 3 Schematic diagram of the decomposition of the surface cleaning device provided by the present application is shown. Figures 1 to 3 As shown, the surface cleaning device includes a body 1, a handle 2, a suction source 3, a sewage tank 4, a floor brush assembly 5 and a clean water tank 6. The body 1 has a first mounting position 111, a second mounting position 112, a third mounting position 113 and a fourth mounting position 114 arranged in sequence from top to bottom, and the handle 2 is installed at the first mounting position 111; the suction source 3 is installed at the second mounting position 112, and the sewage tank 4 is installed at the third mounting position 113. The sewage tank 4 has a water storage cavity, and one end of the sewage tank 4 close to the suction source 3 has a suction port connecting the suction source 3 and the water storage cavity. The suction source 3 sucks water from the surface to be cleaned into the water storage cavity through the suction port; the floor brush assembly 5 is installed at the fourth mounting position 114, and the floor brush assembly 5 includes a floor brush housing 51 and a roller brush 52 rotatably installed on the floor brush housing 51; the clean water tank 6 is installed on the floor brush housing 51 and is used to supply clean water to the roller brush 52.

[0049] Compared with the technical solution in which both the clean water tank 6 and the sewage tank 4 are installed on the body 1, the surface cleaning device provided in the present application installs the clean water tank 6 on the floor brush assembly 5, and only installs the sewage tank 4 on the body 1. The volume of the sewage tank 4 can be increased to avoid the sewage in the sewage tank 4 being sucked into the suction source 3 through the suction port, thereby ensuring that the suction source 3 can work stably and improving the stability of the equipment.

[0050] The surface cleaning device also includes a power supply 7, which is installed in the handle 2 and is used to supply power to the suction source 3. In one embodiment, the power supply 7 can be a secondary battery, which can store power by charging, so that there is no need to connect a charging cable in the working state, which is convenient for users to operate. Furthermore, the floor brush assembly 5 has a charging terminal on the side close to the ground, through which the power supply 7 can be charged.

[0051] The surface cleaning device further includes a control system, which is electrically connected to the power supply 7, and is used to control the opening and closing of the suction source 3 to achieve the suction of sewage from the surface to be cleaned into the sewage tank 4. In one embodiment, the control system includes a PCB 8, which is installed in the handle 2 and is located below the power supply 7.

[0052] In one embodiment, the handle 2 has a first cavity for installing the power supply 7, and the handle 2 also has a second cavity for installing the PCB 8.

[0053] The surface cleaning device further comprises a suction shell, the air outlet of the suction shell is connected to the air inlet of the suction source 3, the air inlet of the suction shell is connected to the suction port, and the suction shell is used to ensure that the suction port is stably connected to the air inlet of the suction source 3. When the suction source 3 is working, the gas in the sewage tank 4 enters the suction shell from the suction port, then enters the air inlet of the suction source 3, and finally is discharged from the air outlet of the suction source 3, so that negative pressure is generated in the sewage tank 4, thereby allowing water from the outside to enter the sewage tank 4.

[0054] The surface cleaning device also includes a mesh plate, which is covered outside the suction port and has an air hole connecting the suction port and the air inlet of the suction shell. The mesh plate is used to prevent large particles of debris in the sewage tank 4 from entering the suction source 3 to ensure that the suction source 3 can work stably.

[0055] When the floor needs to be cleaned, the user can stand on the rear side of the surface cleaning device, hold the handle 2 of the surface cleaning device and push the surface cleaning device to clean the floor. It will take a lot of physical strength for the user to push the surface cleaning device for a long time. In order to reduce the labor intensity of the user when cleaning the floor, the floor brush assembly 5 also includes a roller 53, which is rotatably mounted on the floor brush housing 51, and the wheel surface of the roller 53 can contact the ground, so that the floor brush assembly 5 can roll forward relative to the ground. In one embodiment, the number of rollers 53 is two, and the two rollers 53 are symmetrically mounted on the floor brush housing 51 with the central axis of the floor brush housing 51 as the center, so that the floor brush assembly 5 can stably roll forward relative to the ground.

[0056] The clean water tank 6 includes a first clean water tank and a second clean water tank which are interconnected. The floor brush assembly 5 is provided with at least two rollers 53, and the first clean water tank and the second clean water tank are separated on the sides of the two rollers. Such an arrangement can not only make the overall force of the floor brush assembly 5 balanced, but also increase the gravity of the floor brush assembly 5, so that the floor brush assembly 5 has better stability when walking. The first clean water tank and the second clean water tank are arranged at intervals along the length direction of the roller brush 52. The first clean water tank and the second clean water tank both have a connecting port and are connected by a pipeline to improve the cleaning efficiency of the roller brush 52. The inner diameter of the connecting pipe between the first clean water tank and the second clean water tank is not less than 5 mm to ensure that the clean water can flow smoothly and stably.

[0057] The floor brush assembly 5 further includes a liquid distributor, which is disposed adjacent to the roller brush 52 , and the first clean water tank and / or the second clean water tank are connected to the liquid distributor to supply clean water to the roller brush 52 through the liquid distributor.

[0058] The first clean water tank and / or the second clean water tank is provided with a liquid inlet, and the liquid inlet is used to inject liquid into the first clean water tank and / or the second clean water tank. A cover body is provided at the liquid inlet, and the cover body is used to cover the liquid inlet, so as to close the above-mentioned liquid inlet when no liquid replenishment is required, so as to prevent the water in the clean water tank from overflowing from the liquid inlet.

[0059] In order to facilitate the installation of the clean water tank, the first clean water tank and the second clean water tank are respectively connected to the floor brush assembly 5. For example, the first clean water tank and the second clean water tank are both provided with a slot and / or a protrusion, and the floor brush assembly 5 is provided with a protrusion and / or a slot, and the slot on one component can be connected with the protrusion on another component.

In another embodiment, the first clean water tank and the second clean water tank are both provided with a protrusion, and the floor brush assembly 5 is provided with a slot, and the first clean water tank and the second clean water tank are detachably installed on the floor brush assembly 5 through the cooperation of the slot and the protrusion. In another embodiment, the first clean water tank and the second clean water tank are both provided with a protrusion and a groove, and the floor brush assembly 5 is provided with a groove and a protrusion. The groove of the floor brush assembly 5 is engaged with the protrusion on the first clean water tank and the second clean water tank, and the protrusion on the floor brush assembly 5 is engaged with the groove on the first clean water tank and the second clean water tank, so as to realize the detachable installation of the first clean water tank and the second clean water tank on the floor brush assembly 5.

[0060] The body 1 and the floor brush assembly 5 are rotatably connected to facilitate the user to adjust the angle between the body 1 and the floor brush assembly 5 according to the cleaning needs, so as to clean the floor at different positions and angles. In one embodiment, the floor brush housing 51 has a rotation hole 511 arranged parallel to the roller brush 52; the body 1 includes a body 11 and a rotation shaft 12 fixed to the lower end of the body 11, and the rotation shaft 12 can be rotatably installed in the rotation hole 511 to enable the body 11 to rotate relative to the floor brush assembly 5. Furthermore, there are two rotation holes 511, and the two rotation holes 511 are symmetrically arranged with the central axis of the floor brush housing 51 as the center, and the two ends of the rotation shaft 12 are respectively rotatably matched with one rotation hole 511.

[0061] In one embodiment, the third installation position 113 is a receiving groove, and the sewage tank 4 is detachably installed in the receiving groove. When the sewage tank 4 is installed in the receiving groove of the fuselage body 11, the outer surface of the sewage tank 4 is flush with the outer surface of the fuselage body 11, and the assembly of the fuselage body 11 and the sewage tank 4 forms a cylindrical whole (see Figure 1 ), which can improve the aesthetics of the equipment.

[0062] The body 11 and the handle 2 are detachably connected via an elastic convex.
