Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a liquid storage component and a cleaning device. Background Technology

[0002] With the development of society and economy, home cleaning has gradually entered the era of intelligence and mechanization. The emergence of floor cleaning robots has further relieved people of the heavy workload in home cleaning and reduced the fatigue of home cleaning.

[0003] Floor scrubbing robots are machines used to clean dust, stains, and other debris from floors. However, due to the unreasonable placement of the clean water tank, waste water tank, and pump assembly in existing floor scrubbing robots, when problems arise with the airtightness of the clean water or waste water tanks, it is necessary to disassemble other components already installed on the floor scrubbing machine (e.g., dust box, pump, etc.) to check the pipe connections, which is very inconvenient. Therefore, it is necessary to improve the existing technology to overcome the aforementioned shortcomings. Utility Model Content

[0039] Example 1

[0040] This invention provides a liquid storage component for storing liquids. The liquid can be various cleaning solutions with cleaning functions, municipal water, sewage, or other types of liquids. Figures 1 to 3 As shown, the liquid storage assembly includes a first liquid storage container 100, a second liquid storage container 200, and a drive assembly 300. The first liquid storage container 100 has a first chamber, and the second liquid storage container 200 has a second chamber 201. The drive assembly 300 is used to deliver external liquid into the first chamber and the second chamber 201. The first chamber and the second chamber 201 can be independent of each other or can be selectively connected.

[0041] In this embodiment, the second liquid storage container 200 is disposed on the first liquid storage container 100, and the drive assembly 300 is disposed on the first liquid storage container 100 and / or the second liquid storage container 200. That is, the first liquid storage container 100, the second liquid storage container 200, and the drive assembly 300 are connected to form a modular assembly. After the first liquid storage container 100, the second liquid storage container 200, and the drive assembly 300 form a modular assembly, installation and airtightness testing are facilitated. During airtightness testing, if air leakage, liquid leakage, or other problems affecting airtightness are found, pipeline troubleshooting can be easily performed.

[0042] In this embodiment of the disclosure, at least two of the first liquid storage container 100, the second liquid storage container 200, and the drive assembly 300 are arranged in a vertically stacked configuration. This vertically stacked layout saves horizontal space compared to placing them side-by-side in the horizontal direction, resulting in a more compact structure.

[0043] For ease of description, the following explanation uses the application of the liquid storage component in a floor cleaning robot as an example, wherein the first liquid storage container 100 is a clean water tank and the second liquid storage container 200 is a wastewater tank. It is understood that the scope of protection of the embodiments of this disclosure is not limited thereto.

[0044] Preferably, both the second liquid storage container 200 and the drive assembly 300 are disposed on the first liquid storage container 100. For example... Figure 4 and Figure 7 As shown, a recessed area is formed on the first liquid storage container 100, located on the outside of the first liquid storage container 100 and independently distributed from the first chamber. A second liquid storage container 200 and a drive assembly 300 are disposed in the recessed area. The recessed area includes a first groove 150 for accommodating the second liquid storage container 200 and a second groove 160 for accommodating the drive assembly 300.

[0045] In this embodiment, the projections of the second liquid storage container 200 and the drive assembly 300 in the front-to-back direction partially overlap, and their projections in the left-to-right direction also partially overlap. Consequently, the projections of the first groove 150 and the second groove 160 in the front-to-back direction partially overlap, and their projections in the left-to-right direction also partially overlap. This distribution method fully utilizes the space of the first liquid storage container 100, and makes the modular assembly formed by the first liquid storage container 100, the second liquid storage container 200, and the drive assembly 300 compact and space-saving. It is worth noting that the up, down, left, right, front, and back directions in this embodiment are relative to the attached... Figure 1 The directions refer to up, down, left, right, front, and back. Specifically, front refers to the direction closer to the observer, and back refers to the direction farther from the observer; up and down are relative to the direction of gravity; left and right correspond to the left and right sides of the observer's viewpoint.

[0046] The first groove 150 and the second groove 160 have openings formed on the first liquid storage container 100. The second liquid storage container 200 is disposed within the first groove 150 through the opening on the first groove 150, and the drive assembly 300 is disposed within the second groove 160 through the opening on the second groove 160. The opening direction on the first groove 150 and the opening direction on the second groove 160 can be the same or different. The first groove 150 and the second groove 160 can be independent or connected to form a larger groove. The first groove 150 and the second groove 160 can be relatively regular grooves or irregularly shaped grooves.

[0047] The first groove 150 is located at or near the center of the first liquid storage container 100. Specifically, the opening formed by the first groove 150 on the front wall of the first liquid storage container 100 is located at the center of the front wall. The term "center" refers to the center along the length of the leftmost and rightmost ends of the outer contour of the first liquid storage container 100. Positioning the second liquid storage container 200 at the center of the first liquid storage container 100 facilitates center of gravity optimization and motion stability. Furthermore, the second liquid storage container 200 is located slightly below the center of the first liquid storage container 100. This arrangement lowers the center of gravity and makes the structure more compact.

[0048] In this embodiment, the first liquid storage container 100 and the second liquid storage container 200 constitute a nested double-container structure. The second liquid storage container 200 is partially enclosed by the first chamber of the first liquid storage container 100. The projections of the first chamber and the second chamber 201 in the vertical direction at least partially overlap. Figure 7 As shown, the first chamber is generally inverted "L" shape, including a horizontally extending horizontal cavity 101 and a vertical cavity 102 located below the horizontal cavity 101, with the horizontal cavity 101 and the vertical cavity 102 connected. The horizontal cavity 101 is longer than the vertical cavity 102 in the horizontal direction, forming a receiving space on one side of the vertical cavity 102, within which the second liquid storage container 200 is at least partially located. The projections of the drive assembly 300 and the first chamber in the left-right direction at least partially overlap. The second groove 160 is distributed near the side of the first liquid storage container 100, facilitating the distribution and connection of pipelines.

[0049] The first liquid storage container 100 is provided in two separate parts, including a lower body 180 and an upper cover 190 detachably disposed on the lower body 180. The aforementioned recessed area can be located on the lower body 180, or it can be formed by the lower body 180 and the upper cover 190. Preferably, the recessed area is located on the lower body 180, because the volume of the lower body 180 is larger than the volume of the upper cover 190, providing sufficient space for the recessed area.

[0050] For ease of assembly and disassembly, the second liquid storage container 200 is detachably mounted on the first liquid storage container 100. Specifically, the connection between the second liquid storage container 200 and the first liquid storage container 100 can be a snap-fit ​​connection, a connection via fasteners (screws), or a magnetic connection, etc. When the second liquid storage container 200 and the first liquid storage container 100 are connected by a snap-fit, one of the second liquid storage container 200 and the first liquid storage container 100 has a movable buckle, and the other has a slot that mates with the movable buckle. The drive assembly 300 is connected to the first liquid storage container 100 via fasteners (screws).

[0051] In the embodiments disclosed herein, such as Figure 4 As shown, the drive assembly 300 includes a first drive member 310 acting on the first liquid storage container 100 and a second drive member 320 acting on the second liquid storage container 200. The first drive member 310 is in fluid communication with the first chamber, forming a first fluid passage; the second drive member 320 is in fluid communication with the second chamber 201, forming a second fluid passage. Both the first drive member 310 and the second drive member 320 are pump bodies. The projections of the first drive member 310 and the second drive member 320 in the vertical direction at least partially overlap to fully utilize space.

[0052] The types of the first driving member 310 and the second driving member 320 can be determined according to the liquid inlet method of the first liquid storage container 100 and the second liquid storage container 200. In one embodiment, the first driving member 310 uses a positive pressure (i.e., pressurized output) method to deliver the liquid, applying pressure to the liquid through mechanical action to overcome resistance and deliver it to the target location, for example, a centrifugal pump or a diaphragm pump. The second driving member 320 uses a negative pressure method to deliver the liquid, creating a low-pressure (vacuum) environment inside the pump, using atmospheric pressure to force the dirty liquid generated by the wet cleaning component (roller, rag, or conveyor belt rag) during the cleaning task into the pump. The second driving member 320 can be a vacuum pump, a negative pressure pump, etc.

[0053] Furthermore, such as Figure 1 As shown, the second liquid storage container 200 and the drive assembly 300 are located within the outline of the first liquid storage container 100. That is, the second liquid storage container 200 and the drive assembly 300 are respectively located within the first groove 150 and the second groove 160, ensuring that the outlines of the second liquid storage container 200 and the drive assembly 300 do not extend beyond the outer edge of the outline of the first liquid storage container 100. Therefore, during installation, installation space can be reserved according to the shape and size of the first liquid storage container 100 to facilitate installation.

[0054] Of course, the installation methods between the first liquid storage container 100, the second liquid storage container 200, and the drive assembly 300 include, but are not limited to, the second liquid storage container 200 and the drive assembly 300 being disposed on the first liquid storage container 100. Alternatively, the second liquid storage container 200 can be disposed on the first liquid storage container 100, and the drive assembly 300 can be disposed on the second liquid storage container 200. Or, the second liquid storage container 200 can be disposed on the first liquid storage container 100, and the drive assembly 300 can be partially disposed on the first liquid storage container 100 and partially disposed on the second liquid storage container 200. The following description uses the example of both the second liquid storage container 200 and the drive assembly 300 being disposed on the first liquid storage container 100, but as can be seen from the above description, the scope of protection of the embodiments of this disclosure is not limited thereto.

[0055] In this embodiment, all interfaces on the second liquid storage container 200 for connecting to the drive assembly 300 are located on the first liquid storage container 100. This arrangement simplifies the pipeline layout, shortens pipeline length, avoids complex intersection designs, and reduces the complexity of the pipeline structure. Furthermore, having all interfaces on the second liquid storage container 200 located on the first liquid storage container 100 enhances the sealing design (e.g., using a shared sealing ring), reducing the risk of leaks at multiple locations. Preferably, the interfaces on the second liquid storage container 200 for connecting to the drive assembly 300 are located on the same side of the first liquid storage container 100. When leaks or blockages occur during airtightness testing, the user only needs to check the interfaces on the same side, simplifying troubleshooting.

[0056] like Figure 2 As shown, the container wall of the first liquid storage container 100 is also provided with a plurality of intermittently distributed ribs 103. The plurality of ribs 103 are used to form a wiring space for pipelines on the container wall of the first liquid storage container 100. The pipelines are housed in the above-mentioned space, which on the one hand can limit the posture of the pipelines and prevent the pipelines from changing position and becoming loose from the interface; on the other hand, it makes the pipeline wiring more aesthetically pleasing.

[0057] Continue reading Figure 2 As shown, the first liquid storage container 100 is provided with a first interface 110 communicating with the second chamber 201 for allowing sewage to enter the second chamber 201, and a second interface 120 communicating with the second chamber 201 and connected to the drive assembly 300. The first interface 110 and the second interface 120 are located on the groove wall of the first groove 150, which is the groove wall opposite to the opening of the first groove 150.

[0058] like Figure 5As shown, the second liquid storage container 200 is provided with a second container inlet 210 that mates with the first interface 110 and a second container outlet 220 that mates with the second interface 120. The second container inlet 210 is the inlet for wastewater in the second chamber 201, and the second container outlet 220 is the outlet for air extraction from the second chamber 201. The second container inlet 210 and the second container outlet 220 are respectively connected to the second chamber 201. One of the second container inlet 210 and the first interface 110 is a male connector, and the other is a female connector. The term "male connector" refers to a protruding structure, and "female connector" refers to a recessed structure.

[0059] The first interface 110 can be considered as an extension of the second container inlet 210, and the second interface 120 can be considered as an extension of the second container outlet 220. The first interface 110 is the interface between the second liquid storage container 200 and the external liquid. The inlet of the second drive unit 320 is connected to the second interface 120 through the third pipe 430. When the second drive unit 320 is working, it extracts the gas in the second chamber 201 through the third pipe 430, making the second chamber 201 a negative pressure state, thereby enabling the sewage from the external environment to be drawn into the second chamber 201 through the first interface 110. The first interface 110 and the outlet of the second drive unit 320 can be understood as the upstream and downstream ends of the second flow path.

[0060] It is worth noting that the installation direction between the second liquid storage container 200 and the first liquid storage container 100 is consistent with the insertion direction of the second container inlet 210 and the second container outlet 220, so that the second container inlet 210 can be connected to the first interface 110 and the second container outlet 220 can be connected to the second interface 120.

[0061] To ensure the airtight connection between the first liquid storage container 100 and the second liquid storage container 200, and to prevent liquid or gas from overflowing between the second container inlet 210 and the first interface 110, and between the second container outlet 220 and the second interface 120, in the embodiments of this disclosure, the second container inlet 210 and the first interface 110, and the second container outlet 220 and the second interface 120 are sealed together.

[0062] like Figure 6 and Figure 7 As shown, the first liquid storage container 100 and / or the second liquid storage container 200 are provided with a sealing element 500, which surrounds the connection between the second container inlet 210 and the first interface 110, and the second container outlet 220 and the second interface 120. Preferably, the sealing element 500 is made of soft rubber and is disposed on the groove wall of the first groove 150. Considering that the docking structure between the second container inlet 210 and the first interface 110 is the same as the docking structure between the second container outlet 220 and the second interface 120, for ease of description, the following description only focuses on the docking structure between the second container inlet 210 and the first interface 110.

[0063] After the second liquid storage container 200 is inserted into the first groove 150, the soft rubber is compressed at the same time that the second container inlet 210 aligns with the first interface 110, achieving a partial seal so that liquid and gas will not overflow from the installation gap between the second container inlet 210 and the first interface 110.

[0064] Regarding the first liquid storage container 100, the first liquid storage container 100 is provided with a first container inlet 130 that communicates with the first chamber and is connected to the first drive component 310, an adapter 140 that connects the drive component 300 and the external interface 230, an exhaust port 170 that communicates with the external environment, and an outlet 181 for discharging liquid.

[0065] The first drive unit 310 is connected to the adapter 140 and the first container inlet 130 via the first pipe 410 and the second pipe 420, respectively. The first container inlet 130 is the inlet of the first liquid storage container 100, through which clean water enters the first chamber and is stored. During the process of the first drive unit 310 pumping clean water into the first chamber, the gas in the first chamber is discharged to the external environment through the exhaust port 170.

[0066] like Figure 1 As shown, the external interface 230 is located on the wall of the second liquid storage container 200. The wall of the second chamber 201 is also provided with a connection port 240 that mates with the adapter 140. The adapter 140 can be regarded as an extension of the connection port 240, and the external interface 230 is connected to the adapter 140.

[0067] Specifically, such as Figure 3 As shown, a fourth pipe 440 is provided in the second chamber 201. One end of the fourth pipe 440 is connected to the external interface 230, and the other end is connected to the connector 240. Since the connector 240 is inserted into the adapter 140, liquid entering the fourth pipe 440 through the external interface 230 can enter the first pipe 410 through the adapter 140. Liquid in the first pipe 410 enters the first drive member 310 through the inlet, flows to the second pipe 420 through the outlet of the first drive member 310, and finally enters the first chamber through the first container inlet 130. A seal 500 is also provided between the connector 240 and the adapter 140. The external interface 230 and the vent 170 can be understood as the upstream and downstream ends of the first fluid passage.

[0068] The first liquid storage container 100 and / or the second liquid storage container 200 are provided with airtight ports 600 that can communicate with the first fluid passage and the second fluid passage. Preferably, as follows: Figure 1 and Figure 6As shown, two airtight ports 600 are provided on the first liquid storage container 100, corresponding to the first liquid storage container 100 and the second liquid storage container 200 respectively. The two airtight ports 600 are defined as the first airtight port 610 and the second airtight port 620. The first airtight port 610 is connected to the exhaust port 170 of the first liquid storage container 100 through a first extended pipe 611, and the second airtight port 620 is connected to the outlet of the second driving component 320 through a second extended pipe 621. Thus, the first airtight port 610 can form an airtightness detection path between itself and the external interface 230 through a first fluid passage; the second airtight port 620 can form an airtightness detection path between itself and the first interface 110 through a second fluid passage.

[0069] When testing the airtightness of the first fluid passage where the first liquid storage container 100 and the first driving component 310 are located, the two ends of the testing device (not shown) can be connected to the external interface 230 and the first airtight port 610, respectively. When testing the airtightness of the second fluid passage where the second liquid storage container 200 and the second driving component 320 are located, the two ends of the testing device can be connected to the first interface 110 and the second airtight port 620, respectively, which greatly simplifies the airtightness testing process.

[0070] Example 2

[0071] This utility model also provides a cleaning device (not shown in the figure), which includes the liquid storage component described in Embodiment 1. In one application scenario, the cleaning device is a floor scrubbing robot used to clean surfaces to be cleaned. Of course, the cleaning device includes, but is not limited to, floor scrubbing robots, and can also be window cleaning robots, etc.

[0072] The system comprises a first storage container 100, which serves as the clean water tank for the floor cleaning robot; a second storage container 200, which serves as the wastewater tank for the floor cleaning robot; and a drive assembly 300, which acts as a pump for both the clean water and wastewater tanks. The drive assembly 300 includes a water pump connected to the clean water tank and a vacuum pump (wastewater pump) connected to the wastewater tank. The water pump draws water from the external environment into the clean water tank. The vacuum pump creates negative pressure in the wastewater tank, drawing wastewater generated at the cleaning components of the floor cleaning robot into the wastewater tank.

[0073] In the embodiments of this disclosure, the wastewater tank and the pump body are placed on the clean water tank to form a vertical stacked layout. The vertical layout saves more horizontal space than the side-by-side placement, which is suitable for miniaturization of the machine body and can optimize the internal installation space of the floor cleaning robot, making the structure more compact.

[0074] In existing technologies, the clean water tank, wastewater tank, water pump, and vacuum pump are distributed throughout the robot body. For example, the wastewater tank and vacuum pump are fixed to the cleaning module of the robot body, while the water pump is fixed to the base of the robot body. This results in spatial overlap between the clean water tank, wastewater tank, water pump, and vacuum pump and other modules on the robot body (cleaning module, dust box, etc.). Therefore, before measuring airtightness, these other modules must be assembled before airtightness testing can be performed. If an airtightness test fails, the aforementioned modules must be disassembled to troubleshoot the connecting pipes between the clean water tank, wastewater tank, water pump, and vacuum pump. This process is time-consuming, labor-intensive, and extremely inconvenient.

[0075] In the embodiments of this disclosure, by mounting the wastewater tank, water pump, and vacuum pump on the clean water tank, the clean water tank, wastewater tank, water pump, and vacuum pump are connected as modular components, enabling modular installation of the clean water tank, wastewater tank, water pump, and vacuum pump. During installation, the clean water tank, wastewater tank, water pump, and vacuum pump will not intersect with other modules on the robot body. When performing airtightness testing, only the clean water tank, wastewater tank, water pump, and vacuum pump need to be installed on the robot body; it is not necessary for other modules to be installed on the robot body as a prerequisite.

[0076] In embodiments of this disclosure, such as Figure 6 As shown, the bottom of the first liquid storage container 100 is also provided with a decorative plate 700, and an airtight port 600 is provided through the decorative plate 700.

[0077] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
