Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device. Background Technology

[0002] Cleaning equipment such as robotic vacuum cleaners and floor scrubbers typically require components such as roller brushes, water suction motors, and water pumps to work together to achieve functions such as floor cleaning, wastewater recycling, and drying.

[0003] In related technologies, cleaning equipment includes a main body and a floor brush unit. The floor brush unit includes a suction pipe, a floor brush housing, a roller brush module, a drive module, a steam module, and a cleaning liquid module.

[0004] However, the layout of the various modules in the current cleaning equipment floor brush device is still unreasonable and needs further optimization. Summary of the Invention

[0005] In a first aspect, this application provides a cleaning device, comprising:

[0006] body;

[0007] The floor brush unit is connected to the main body and includes:

[0008] Floor brush shell;

[0009] A roller brush module is disposed at one end of the floor brush housing along a first direction, and the axis of the roller brush module is perpendicular to the first direction; the roller brush module is configured to rotate relative to the floor brush housing to clean the surface to be cleaned.

[0010] The suction pipe is located at the center of the floor brush housing along the second direction, which is consistent with the axial direction of the roller brush module.

[0011] The steam module is located on the first side of the suction pipe along the second direction;

[0012] A drive module, connected to the roller brush module, is configured to drive the roller brush module to move relative to the floor brush housing such that the roller brush module extends at least partially beyond the planar coverage area of ​​the floor brush housing; the drive module is located on a second side of the suction pipe along a second direction;

[0013] The cleaning fluid module is located on the second side of the suction pipe along the second direction.

[0014] In related technologies, to reduce the amount of cleaning fluid piping in floor brush devices and facilitate pipeline layout and installation, the steam module and the cleaning fluid module are usually placed adjacent to each other. However, the applicant has found that because the steam module operates at a high temperature, it affects the heat dissipation of the pump body in the cleaning fluid module, thereby affecting the service life of the cleaning fluid pump and the accuracy of cleaning fluid metering, resulting in inaccurate water or air output, thus affecting the user experience of the cleaning equipment. The cleaning equipment provided in this application embodiment has a suction pipe located at the center of the floor brush housing along a second direction. The second direction is aligned with the axial direction of the roller brush module. The steam module is located on the first side of the suction pipe along the second direction. The drive module is located on the second side of the suction pipe along the second direction. The cleaning fluid module is located on the second side of the suction pipe along the second direction. By placing the steam module and the cleaning fluid module on opposite sides of the suction pipe, the steam module and the cleaning fluid module are effectively separated, thereby reducing the impact of the steam module on the cleaning fluid module, significantly improving the heat dissipation of each pump body in the cleaning fluid module, and thus improving the user experience of the current cleaning equipment.

[0015] Meanwhile, due to the large size and weight of the steam module, it is separately positioned on the first side of the suction pipe along the second direction. The smaller, lighter drive module and cleaning fluid module are placed together on the second side of the suction pipe along the second direction. This results in a more even weight distribution of the floor brush unit along the axial direction of the roller brush module. Therefore, the floor brush unit is less prone to poor cleaning performance and user experience caused by uneven weight distribution. Furthermore, the layout of the steam module, cleaning fluid module, and drive module according to their volume ensures a rational and efficient use of the floor brush housing space.

[0016] In some embodiments, the cleaning fluid module includes a cleaning fluid pump and a solution pump, which are located on a second side of the suction pipe along a second direction;

[0017] The steam module includes a steam pump and a steam generator, which are located on the first side of the suction pipe along the second direction.

[0018] This allows for a better balance between the weight of the steam pump and the steam generator and the weight of the cleaning fluid pump and the solution pump.

[0019] In some embodiments, the floor brush device further includes a connecting module, which is disposed at the center of the floor brush housing along a second direction, and the connecting module is located on the side opposite to the roller brush module along a first direction. The connecting module is used to connect to the body of the cleaning device.

[0020] This ensures that after the body is connected, the center of gravity of the body is located at the center of the brush housing along the second direction.

[0021] In some embodiments, along a first direction, a cleaning fluid pump is located on the side of the connecting module facing the roller brush module, and a solution pump is located on the side of the connecting module away from the roller brush module.

[0022] Because the space on the side of the connecting module away from the roller brush module is smaller, while the space on the side of the connecting module facing the roller brush module is larger, the volume of the cleaning fluid pump is larger than that of the solution pump. Therefore, the cleaning fluid pump is located on the side of the connecting module facing the roller brush module, and the solution pump is located on the side of the connecting module away from the roller brush module to facilitate the installation of the cleaning fluid pump and the solution pump.

[0023] In some embodiments, the floor brush device includes two elastic components disposed on opposite sides of the connecting module along a second direction;

[0024] Along the first direction, the steam pump is located on one side of an elastic component facing away from the roller brush module, and the solution pump is located on the other side of an elastic component facing away from the roller brush module.

[0025] Among them, the elastic component can provide a force to restore the body to an upright position when the body is not in an upright position, so that the user can reduce the hand grip force when using the cleaning equipment and improve the user's hand grip experience. The elastic component includes, but is not limited to, coil spring components, torsion spring components, etc.

[0026] This design effectively separates the steam pump and steam generator in the steam module using elastic components, reducing the impact of the high temperature of the steam generator on the steam pump. Simultaneously, placing the solution pump behind another elastic component effectively balances gravity distribution. Furthermore, this arrangement allows for efficient use of the space on the side of the elastic component away from the roller brush module, improving the utilization rate of the brush housing space.

[0027] In some embodiments, along a first direction, a steam pump is located on the side of the connecting module away from the roller brush module, and a steam generator is located on the side of the connecting module facing the roller brush module.

[0028] Because the space on the side of the connecting module away from the roller brush module is smaller, while the space on the side facing the roller brush module is larger, the steam pump is smaller than the steam generator. Therefore, placing the steam pump on the side of the connecting module away from the roller brush module and the steam generator on the side facing the roller brush module facilitates the installation of both the steam pump and the steam generator.

[0029] In some embodiments, along the second direction, the steam pump and the solution pump are located on opposite sides of the connecting module.

[0030] Since the steam pump and the solution pump are similar in weight and volume, and are located on opposite sides of the connecting module along the second direction, it is advantageous for the center of gravity of the floor brush device to be located at the center of the floor brush housing along the second direction.

[0031] In some embodiments, the drive module includes a drive element and a gear, and the brush module is provided with a rack that matches the gear.

[0032] The drive unit and gear are located on the second side of the suction pipe along the second direction.

[0033] In this way, the drive components and gears can be used to balance the weight of the steam module.

[0034] In some embodiments, along the second direction, the cleaning fluid pump is located on the side of the drive module away from the steam module.

[0035] In this way, the cleaning fluid pump is far from the steam module, and the heat emitted by the steam module after the temperature rises is less likely to affect the cleaning fluid pump.

[0036] In some embodiments, the steam module includes a reversing valve located on the side of the steam generator facing the brush module in a first direction.

[0037] The reversing valve is used to switch between hot water and steam. The hot water and steam output positions are close to the roller brush module. The reversing valve is located on the side of the steam generator facing the roller brush module, which helps to shorten the length of the pipeline on the side of the reversing valve facing the roller brush module.

[0038] In some embodiments, the steam module includes a scale inhibitor box located between the connecting module and the steam generator along a first direction.

[0039] In this way, the scale inhibitor box is close to the steam generator, making it easier for the steam generated by the steam generator to enter the scale inhibitor box. Moreover, the heat generated by the steam generator has a smaller impact on the scale inhibitor box. By placing the scale inhibitor box close to the steam generator and keeping the steam pump away from the steam generator, damage to the steam pump caused by the heat generated by the steam generator can be effectively avoided.

[0040] In some embodiments, the brush housing also includes two wheels, which are disposed at one end of the brush housing away from the roller brush module along a first direction and at both ends of the brush housing along a second direction.

[0041] Along the second direction, the steam pump and the solution pump are located between the two traveling wheels.

[0042] This allows for the use of the space between the two wheels, improving the utilization rate of the brush holder space.

[0043] In some embodiments, a control panel is also included, located along a second direction on the side of the cleaning fluid pump away from the steam module.

[0044] In this way, the control panel is far from the steam module, and the heat emitted by the steam module after the temperature rises is less likely to affect the cleaning fluid pump. Attached Figure Description

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0060] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0061] As described in the background section, the floor brush device includes a suction pipe, a floor brush housing, a roller brush module, a drive module, a steam module, and a cleaning fluid module. In related technologies, to reduce the number of cleaning fluid lines in the floor brush device and facilitate pipeline layout and installation, the steam module and the cleaning fluid module are usually placed adjacent to each other. However, the applicant has found that because the steam module operates at a high temperature, it affects the heat dissipation of the pump body in the cleaning fluid module, thereby affecting the service life of the cleaning fluid pump and the accuracy of cleaning fluid metering, resulting in inaccurate water or air output, thus impacting the user experience of the cleaning equipment.

[0062] Furthermore, the steam module is heavier than the drive module, which in turn is heavier than the cleaning fluid module. In related technologies, the steam and cleaning fluid modules are located on one side of the suction pipe along the axis of the roller brush module, while the drive module is located on the other side. Therefore, the weight distribution of the floor brush unit along the axis of the roller brush module is uneven. During use, this uneven weight distribution causes the center of gravity of the cleaning equipment to shift. When the user holds or pushes the brush, the handle experiences unilateral tension / pressure, resulting in a "deviation towards the heavier side." This requires continuous force to correct the direction, and prolonged use can easily lead to hand and arm fatigue. For example, if the left side of the floor brush is heavier, pushing it forward will automatically cause it to veer to the left, requiring deliberate effort to apply force to the right during cleaning, significantly reducing operational smoothness and affecting user comfort. Moreover, uneven pressure on the floor brush increases cleaning blind spots. The contact pressure between the floor brush device and the ground is determined by the weight distribution. If the pressure on the heavier side is too high, the lighter side will not be able to effectively contact the ground. This will result in the roller brush module on the lighter side not being able to make full contact with the ground, making it difficult to clean the dirt (such as stubborn oil stains and dust) and creating cleaning blind spots. On the other hand, excessive pressure on the heavier side may also wear down the ground (such as wooden floors and ceramic tile glaze) or cause excessive wear on the roller brush in certain areas.

[0063] Based on this, this application provides a cleaning device. The floor brush device includes a floor brush housing, a roller brush module, a suction pipe, a steam module, a drive module, and a cleaning fluid module. The suction pipe is located at the center of the floor brush housing along a second direction. This second direction is aligned with the axial direction of the roller brush module. The steam module is located on the first side of the suction pipe along the second direction. The drive module is located on the second side of the suction pipe along the second direction. The cleaning fluid module is located on the second side of the suction pipe along the second direction. By separately positioning the steam module and the cleaning fluid module on opposite sides of the suction pipe, the steam module and the cleaning fluid module are effectively separated, thereby reducing the impact of the steam module on the cleaning fluid module and significantly improving the heat dissipation of the pumps in the cleaning fluid module, thus improving the user experience of current cleaning equipment.

[0064] Meanwhile, due to the large size and weight of the steam module, it is separately positioned on the first side of the suction pipe along the second direction. The smaller, lighter drive module and cleaning fluid module are placed together on the second side of the suction pipe along the second direction. This results in a more even weight distribution of the floor brush unit along the axial direction of the roller brush module. Therefore, the floor brush unit is less prone to poor cleaning performance and user experience caused by uneven weight distribution. Furthermore, the layout of the steam module, cleaning fluid module, and drive module according to their volume ensures a rational and efficient use of the floor brush housing space.

[0065] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0066] The cleaning equipment can be a floor scrubber, such as a fully automatic floor scrubber, a semi-automatic floor scrubber, a walk-behind floor scrubber, or a ride-on floor scrubber. In some embodiments, the cleaning equipment can be a vacuum cleaner or a robotic vacuum cleaner with a floor scrubbing function.

[0067] In this embodiment, a floor scrubber is used as an example of the cleaning equipment described above.

[0068] Figure 1 A schematic diagram of the cleaning equipment provided in this application.

[0069] See Figure 1 As shown, the cleaning equipment includes a floor brush device 100, which is the part of the cleaning equipment that contacts the surface to be cleaned. The cleaning equipment cleans the surface to be cleaned through the floor brush device 100.

[0070] The cleaning equipment includes a body 200. The body 200 is the main supporting structure of the cleaning equipment, and it is connected above the floor brush device 100, or in other words, the floor brush device 100 is connected to the bottom of the body 200. The body 200 may include a housing and some components housed within the housing. The components within the housing, together with the components within the floor brush device 100, form a cleaning fluid supply system and a dirt recovery system to achieve the cleaning function of the cleaning equipment.

[0071] The cleaning equipment includes a handle 300. The handle 300 is attached to the upper end of the body 200, and the handle 300 is, for example, integrally formed into the housing. The handle 300 is for the user to hold so that the user can control the forward direction of the cleaning equipment.

[0072] The main motor, located in the body 200, generates vacuum suction to remove dirt from surfaces to be cleaned. These surfaces can include floors, tabletops, carpets, sofas, and mattresses.

[0073] Figure 2 A schematic diagram of the structure of the floor brush device in the cleaning equipment provided in this application after removing part of the floor brush shell. Figure 3 for Figure 2 Top view.

[0074] See Figure 2 and Figure 3 As shown, the floor brush device 100 includes a floor brush housing 110. The floor brush housing 110 has a rectangular structure.

[0075] The floor brush device 100 includes a roller brush module 120. The floor brush housing 110 serves as the basic support structure for the floor brush device 100 and can also be used as a mounting base for other components of the floor brush device 100. The roller brush module 120 includes a roller brush frame and a roller brush. The roller brush frame is connected to the floor brush housing 110, and the roller brush is mounted on the roller brush frame. When the cleaning equipment performs cleaning operations, the roller brush rolls along the surface to be cleaned to clean the surface.

[0076] Specifically, the roller brush module 120 is disposed at one end of the floor brush housing 110 along a first direction, and the axial direction of the roller brush module 120 is perpendicular to the first direction. The first direction can be the direction shown by the Y-axis in the figure.

[0077] The floor scrubber unit 100 includes a suction pipe 130. When scrubbing the floor, the roller brush module 120 mixes clean water / cleaning solution with the floor stains to form wastewater, while simultaneously lifting up solid debris (such as hair, dust, food crumbs, small particles of garbage, etc.). The suction pipe 130 serves as a transport channel, quickly conveying the wastewater and solid debris collected at the suction port of the roller brush module 120 to the wastewater tank in the machine body. For roller brush floor scrubbers, the suction pipe 130 is typically positioned directly below or behind the roller brush's suction port.

[0078] The suction pipe 130 is positioned at the center of the floor brush housing 110 along a second direction, which is aligned with the axial direction of the roller brush module 120. A portion of the suction pipe 130 has an axial direction aligned with the first direction. The axis of this portion of the suction pipe 130 can be... Figure 3 As shown by the straight line o in the middle.

[0079] Specifically, the first direction can be the direction shown by the Y-axis in the figure. The second direction can be the direction shown by the X-axis in the figure. At least a portion of the suction pipe 130 extends along the first direction, and the axis of this portion of the suction pipe 130 coincides with the center plane of the floor brush housing 110 along the second direction.

[0080] The floor brush device 100 includes a steam module 140. The steam module 140 can be used to deliver hot water to the roller brush module 120 or to deliver steam to the surface to be cleaned, thereby achieving high-temperature cleaning.

[0081] The steam module 140 is located on the first side of the suction pipe 130 along the second direction. The second direction can be the direction shown by the X-axis in the figure.

[0082] The floor brush device 100 includes a drive module 150. The drive module 150 is connected to a roller brush module 120 and is configured to drive the roller brush module 120 to move relative to the floor brush housing 110 such that the roller brush module 120 at least partially extends beyond the planar coverage area of ​​the floor brush housing 110. The drive module 150 is located on a second side of the suction pipe 130 along a second direction.

[0083] Specifically, when cleaning a low-height recessed space, the drive module 150 drives the roller brush module 120 to move along a second direction toward a second side, so that the roller brush module 120 partially extends beyond the planar coverage area of ​​the floor brush housing 110, and the roller brush module 120 cleans the floor of the recessed space. After cleaning, the drive module 150 drives the roller brush module 120 to move along the second direction toward a first side, so that the roller brush module 120 is located within the planar coverage area of ​​the floor brush housing 110. See also... Figure 3 As shown in the figure, the area within the dashed box represents the position of the roller brush module 120 after it has been moved outward.

[0084] The floor brush unit 100 includes a cleaning fluid module 160. The cleaning fluid module 160 is used to supply cold water or cleaning fluid to the roller brush module 120. The cleaning fluid module 160 is located on the second side of the suction pipe 130 along the second direction.

[0085] It is understood that the suction pipe 130 is positioned at the center of the floor brush housing 110 along the second direction. This second direction aligns with the axial direction of the roller brush module 120. The steam module 140 is located on the first side of the suction pipe 130 along the second direction. The drive module 150 is located on the second side of the suction pipe 130 along the second direction. The cleaning fluid module 160 is located on the second side of the suction pipe 130 along the second direction. By positioning the steam module 140 and the cleaning fluid module 160 on opposite sides of the suction pipe 130, they are effectively separated, thereby reducing the impact of the steam module 140 on the cleaning fluid module 160 and significantly improving heat dissipation of the pumps within the cleaning fluid module 160, thus improving the user experience of the current cleaning equipment.

[0086] Meanwhile, due to the large size and weight of the steam module 140, it is separately positioned on the first side of the suction pipe 130 along the second direction. The smaller and lighter drive module 150 and cleaning liquid module 160 are positioned together on the second side of the suction pipe 130 along the second direction. In this way, the weight distribution of the floor brush device 100 is more even along the axial direction of the roller brush module 120. Therefore, the floor brush device 100 is less likely to suffer from poor cleaning performance and poor user experience due to poor weight distribution. Moreover, the layout of the steam module 140, cleaning liquid module 160, and drive module 150 according to their volume is reasonable and makes efficient use of the space in the floor brush housing 110.

[0087] See Figure 2 and Figure 3 As shown, in some embodiments, the cleaning fluid module 160 includes a cleaning fluid pump 161. The cleaning fluid pump 161 is used to deliver cold water from the clean water tank 400 to the roller brush module 120. The clean water tank 400 can be mounted on the body 200, or it can be mounted on the floor brush device 100. The cleaning fluid pump 161 is located on the second side of the suction pipe 130 along a second direction. The second direction can be the direction shown by the X-axis in the figure.

[0088] The cleaning fluid module 160 includes a solution pump 162 for delivering cleaning fluid from the cleaning fluid tank to the roller brush module 120. The solution pump 162 is located on the second side of the suction pipe 130 along a second direction.

[0089] The steam module 140 includes a steam pump 141. The steam pump 141 is connected to the clean water tank 400 of the cleaning equipment via a pipe, and is also connected to the steam generator via a pipe. The steam pump 141 is used to deliver cold water from the clean water tank 400 to the steam generator. The steam pump 141 is located on the first side of the suction pipe 130 along the second direction.

[0090] The steam module 140 includes a steam generator 142. The steam generator 142 heats water to form steam via an internal heater, and the steam is delivered to the surface to be cleaned via a reversing valve and steam pipe for cleaning. Alternatively, the steam generator 142 heats water via its internal heater, and the hot water is delivered to the roller brush module 120 via a reversing valve and hot water pipe. The steam pump 141 and the steam generator 142 are located on the first side of the suction pipe 130 along a second direction.

[0091] It is understood that in this embodiment, the cleaning fluid module 160 includes a cleaning fluid pump 161 and a solution pump 162, which are located on the second side of the suction pipe 130 along the second direction. The steam module 140 includes a steam pump 141 and a steam generator 142, which are located on the first side of the suction pipe 130 along the second direction. This facilitates the weight balance of the cleaning fluid pump 161 and the solution pump 162 by utilizing the weight of the steam pump 141 and the steam generator 142.

[0092] See Figure 2 and Figure 3 As shown, in some embodiments, the floor brush device 100 further includes a connection module 170 for connecting to the body 200 of the cleaning equipment.

[0093] The connecting module 170 is located at the center of the brush housing 110 along the second direction, and is situated on the side of the drive module 150 opposite to the roller brush module 120 along the first direction. A portion of the suction pipe 130 is located within the connecting module 170, thereby communicating with the wastewater tank on the main body 200. The second direction can be the direction shown by the X-axis in the figure.

[0094] It is understandable that the connection module 170 is located at the center of the brush housing 110 along the second direction, which is beneficial to the fact that after the body 200 is connected, the center of gravity of the body 200 is located at the center of the brush housing 110 along the second direction.

[0095] In some embodiments, the floor brush device 100 includes two elastic components disposed on opposite sides of the connecting module 170 along a second direction;

[0096] Along the first direction, the steam pump 141 is located on the side of one elastic component facing away from the roller brush module 120, and the solution pump 162 is located on the side of another elastic component facing away from the roller brush module 120.

[0097] Among them, the elastic component can provide a force to restore the body 200 to an upright position when the body is not in an upright position, so that the user can reduce the hand holding force when using the cleaning equipment and improve the user's hand holding experience. The elastic component includes, but is not limited to, coil spring components, torsion spring components, etc.

[0098] See Figure 2 and Figure 3 As shown, in some embodiments, the floor brush device 100 includes two torsion springs disposed on opposite sides of the connecting module 170 along a second direction.

[0099] Along the first direction, the steam pump 141 is located on one side of the roller brush module 120 away from a torsion spring, and the solution pump 162 is located on the other side of the roller brush module 120 away from a torsion spring.

[0100] In this way, the steam pump 141 and the steam generator 142 in the steam module 140 can be effectively separated by a torsion spring, reducing the impact of the high temperature of the steam generator 142 during operation on the steam pump 141. At the same time, placing the solution pump 162 behind another torsion spring can effectively balance the distribution of gravity. Moreover, this arrangement can make efficient use of the space on the side of the torsion spring away from the roller brush module 120, improving the utilization rate of the space in the brush housing 110.

[0101] It should be noted that the torsion springs are not shown in the attached drawings. One torsion spring is positioned opposite the steam pump 141 along the Y-axis. The other torsion spring is positioned opposite the solution pump 162 along the Y-axis. Both torsion springs can be connected to the shafts on both sides of the connecting module 170, and are also connected to the floor brush housing 110, thereby achieving the reset of the machine body 200 after rotation around the X-axis.

[0102] Alternatively, the torsion springs are connected to the connecting module 170 and the floor brush housing 110 respectively, thereby achieving the reset of the body 200 after rotation around the Z-axis.

[0103] See Figure 2 and Figure 3 As shown, in some embodiments, along a first direction, the cleaning fluid pump 161 is located on the side of the connecting module 170 facing the roller brush module 120, and the solution pump 162 is located on the side of the connecting module 170 away from the roller brush module 120. The first direction can be the direction shown by the Y-axis in the figure.

[0104] Understandably, the space on the side of the connecting module 170 facing away from the roller brush module 120 is smaller, while the space on the side of the connecting module 170 facing the roller brush module 120 is larger, and the volume of the cleaning fluid pump 161 is larger than that of the solution pump 162. Therefore, the cleaning fluid pump 161 is located on the side of the connecting module 170 facing the roller brush module 120, and the solution pump 162 is located on the side of the connecting module 170 facing away from the roller brush module 120 to facilitate the installation of the cleaning fluid pump 161 and the solution pump 162.

[0105] Specifically, the cleaning fluid pump 161 can be a peristaltic pump. The solution pump 162 can be a diaphragm pump. Under the same flow rate and pressure conditions, diaphragm pumps are generally smaller in volume than peristaltic pumps.

[0106] See Figure 2 and Figure 3 As shown, in some embodiments, along the first direction, the steam pump 141 is located on the side of the connecting module 170 away from the roller brush module 120, and the steam generator 142 is located on the side of the connecting module 170 facing the roller brush module 120.

[0107] Understandably, the space on the side of the connecting module 170 away from the roller brush module 120 is smaller, while the space on the side of the connecting module 170 facing the roller brush module 120 is larger, and the volume of the steam pump 141 is smaller than that of the steam generator 142. Therefore, the steam pump 141 is located on the side of the connecting module 170 away from the roller brush module 120, and the steam generator 142 is located on the side of the connecting module 170 facing the roller brush module 120 to facilitate the installation of the steam pump 141 and the steam generator 142.

[0108] Specifically, the steam pump 141 can be a plunger pump, or the steam pump 141 can be a diaphragm pump.

[0109] See Figure 2 and Figure 3 As shown, in some embodiments, along the second direction, the steam pump 141 and the solution pump 162 are located on opposite sides of the connecting module 170.

[0110] Understandably, since the steam pump 141 and the solution pump 162 are similar in weight and volume, and are located on opposite sides of the connecting module 170 along the second direction, it is advantageous for the center of gravity of the floor brush device 100 to be located at the center of the floor brush housing 110 along the second direction.

[0111] See Figure 2 and Figure 3 As shown, in some embodiments, the steam pump 141 and the solution pump 162 are symmetrically arranged about the connecting module 170 along the second direction. The steam pump 141 and the solution pump 162 have similar weight and volume, and their symmetrical arrangement about the connecting module 170 is advantageous because it allows the center of gravity to be located at the center of the bottom shell along the second direction.

[0112] Specifically, the steam pump 141 can be a diaphragm pump. The solution pump 162 can be a diaphragm pump.

[0113] See Figure 2 and Figure 3 As shown, in some embodiments, the steam module 140 includes a reversing valve 143. The steam generator 142 heats water to form steam via its internal heater, and the steam is delivered to the surface to be cleaned via the reversing valve 143 and a steam pipe for cleaning. Alternatively, the steam generator heats water via its internal heater, and the hot water is delivered to the brush module 120 via the reversing valve 143 and a hot water pipe. In a first direction, the reversing valve 143 is located on the side of the steam generator 142 facing the brush module 120. The first direction is the direction indicated by the Y-axis.

[0114] Understandably, the reversing valve 143 is used to switch between hot water and steam. The hot water and steam output positions are close to the roller brush module 120. The reversing valve 143 is located on the side of the steam generator 142 facing the roller brush module 120, which helps to shorten the length of the pipeline on the side of the reversing valve 143 facing the roller brush module 120.

[0115] Specifically, the directional control valve 143 can be a three-way directional control valve. The directional control valve 143 can also be a solenoid directional control valve.

[0116] See Figure 2 and Figure 3As shown, in some embodiments, the steam module 140 includes a scale inhibitor box 144. The scale inhibitor box 144 is used to separate scale from the steam. Along a first direction, the scale inhibitor box 144 is located between the connecting module 170 and the steam generator 142. This close proximity of the scale inhibitor box 144 to the steam generator 142 facilitates the entry of steam generated by the steam generator 142 into the scale inhibitor box 144. Furthermore, the heat generated by the steam generator 142 has a smaller impact on the scale inhibitor box 144. By placing the scale inhibitor box 144 close to the steam generator 142 and the steam pump 141 away from the steam generator 142, damage to the steam pump 141 caused by the heat generated by the steam generator 142 can be effectively avoided.

[0117] The scale inhibitor box 144 can be connected to the steam generator 142. The scale inhibitor box 144 can also be connected to the reversing valve 143. Clean water in the clean water tank 400 is supplied to the steam generator 142. The steam generator 142 heats the water to form steam through its internal heater. The steam generated by the steam generator 142 is injected into the scale inhibitor box 144 to separate the scale. The separated steam is then delivered to the surface to be cleaned through the reversing valve 143 and the steam pipe.

[0118] See Figure 2 and Figure 3 As shown, in some embodiments, the drive module 150 includes a drive element 151 and a gear, and the roller brush module 120 is provided with a rack that matches the gear. The drive element 151 and the gear are located on a second side of the suction pipe 130 along a second direction. The drive element 151 and the gear can be used to balance the weight of the steam module 140.

[0119] When the cleaning equipment is running, the drive unit 151 of the drive module 150 drives the rack of the roller brush module 120 to move via gears, causing the roller brush module 120 to extend at least partially beyond the planar coverage area of ​​the floor brush housing 110 to clean the edge areas. At this time, the cleaning fluid pump 161 of the cleaning fluid module 160 sprays cold water onto the roller brush module 120, or the cleaning fluid pump 161 and solution pump 162 spray cleaning fluid onto the roller brush module 120, or the steam pump 141 of the steam module 140 delivers water to the steam generator 142, where it is heated to produce high-temperature steam. This high-temperature steam is filtered through the scale inhibitor box 144 and then sprayed out, thereby softening stubborn stains on the surface to be cleaned. The suction pipe 130 simultaneously collects the liquid and dust generated during the cleaning process.

[0120] In other embodiments, the drive module 150 includes a drive member. The drive member is located on a second side of the suction pipe 130 along a second direction. The drive member is connected to the roller brush module 120. The drive member drives the roller brush module 120 to move along the second direction. The drive member can be a linear drive member, such as a hydraulic cylinder or an electric actuator.

[0121] See Figure 2 and Figure 3 As shown, in some embodiments, along the second direction, the cleaning fluid pump 161 is located on the side of the drive module 150 away from the steam module 140. In this way, the cleaning fluid pump 161 is far away from the steam module 140, and the heat emitted by the steam module 140 after the temperature of the steam module 140 rises is less likely to affect the cleaning fluid pump 161.

[0122] Moreover, when the gear drives the rack to move in the second direction toward the first side, thereby causing the roller brush module 120 to extend from the first side, and when the gear drives the rack to move in the second direction toward the second side, thereby causing the roller brush module 120 to extend from the first side, the position of the drive module 150 is closer to the center of the second direction, and the difference in the displacement distance of the rack is small when it extends from both sides.

[0123] Specifically, along the second direction, the cleaning fluid pump 161 is located on the side of the drive unit 151 opposite to the steam module 140.

[0124] See Figure 2 and Figure 3 As shown, in some embodiments, a control board 180 is also included, located along the second direction on the side of the cleaning fluid pump 161 opposite to the steam module 140.

[0125] In this way, the control panel 180 is far from the steam module 140, and the heat emitted by the steam module 140 after the temperature rises is less likely to affect the cleaning liquid pump 161.

[0126] Specifically, the control board 180 is in contact with the cleaning fluid pump 161, reducing the distance between the control boards 180 and the cleaning fluid pump 161, thereby making full use of space and resulting in a compact structure. Furthermore, the cleaning fluid pump 161 can be used to cool the control board 180.

[0127] See Figure 2 and Figure 3 As shown, in some embodiments, the floor brush device 100 further includes two wheels 190. The wheels 190 are used to reduce the resistance of user operation and improve mobility and stability.

[0128] Two wheels 190 are positioned at one end of the brush housing 110 away from the roller brush module 120 along a first direction, and two wheels 190 are positioned at both ends of the brush housing 110 along a second direction. Along the second direction, the edges of the wheels 190 are not recessed into the edges of the brush housing 110, and the steam pump 141 and the solution pump 162 are located between the two wheels 190.

[0129] Specifically, along the second direction, the edge of the wheel 190 is flush with the edge of the brush housing 110. Alternatively, along the second direction, the edge of the wheel 190 protrudes beyond the edge of the brush housing 110.

[0130] It is understandable that, compared to the edge of the walking wheel 190 being recessed into the edge of the brush housing 110, the distance between the two walking wheels 190 in the brush device 100 provided in this embodiment can be larger along the second direction, thereby providing installation space for the steam pump 141 and the solution pump 162.

[0131] In some embodiments, the floor brush device 100 includes a power component for driving the walking wheel 190 to rotate.

[0132] Finally, it should be noted that other embodiments of this disclosure will readily arise in the mind of those skilled in the art upon consideration of the specification and practice of the solutions disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
