Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to water tank structures, cleaning equipment and cleaning systems for cleaning equipment. Background Technology

[0002] With the rapid development of cleaning equipment, cleaning robots, floor scrubbers, and other cleaning equipment are widely used in home and commercial settings. These cleaning devices typically use fans to generate negative pressure suction, drawing solid, liquid, and gaseous contaminants (such as dust particles, liquid stains, and humid air) from the floor into the dirt collection area of ​​the cleaning device for temporary storage.

[0003] In related technologies, the gas entering the waste collection area needs to be purified before being discharged by a fan. Currently, gravity separation is commonly used to separate solid waste, sewage, and gas in the waste collection area. Solid waste and sewage move downwards, while lighter gases move upwards. However, gravity separation places high demands on the vertical height of the cleaning equipment. With the trend towards miniaturization in cleaning equipment design, the height of the equipment often fails to meet these gravity separation requirements, resulting in poor separation efficiency and consequently affecting the reliability and durability of the cleaning equipment. Utility Model Content

[0004] This application discloses a water tank structure, cleaning equipment, and cleaning system for cleaning equipment, in order to solve the problem that the height of the cleaning equipment involved in the related technology is difficult to meet the requirements of gravity separation, resulting in poor separation effect.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application disclose a water tank structure for a cleaning device, the disclosed water tank structure including a tank body, a cover body and a separation filter assembly; The interior of the housing has a dirt collection area, and the side wall of the housing has a suction port and an exhaust port. The suction port is connected to the dirt collection area and is used to transfer the dirt collected by the external cleaning components to the dirt collection area. The exhaust port is used to connect to the fan. The cover is placed over the opening of the box, and the inside of the cover is provided with a flow channel. The flow channel has a first opening and a second opening. The first opening faces the dirt collection area, and the second opening is connected to the exhaust port. The separation and filtration assembly is disposed within the flow channel. The separation and filtration assembly includes a baffle plate connected to the inner wall of the flow channel. The baffle plate has a guide hole. The solid part of the baffle plate is disposed opposite to the first opening. The guide hole connects the first opening and the second opening.

[0006] Secondly, this application discloses a cleaning device, which includes a device body and the water tank structure described in the first aspect, wherein the water tank structure is installed inside the device body.

[0007] Thirdly, embodiments of this application disclose a cleaning system, which includes a base station and the cleaning equipment described in the second aspect. The base station has a cabin, and the cleaning equipment is docked inside the cabin.

[0008] The technical solution adopted in this application can achieve the following technical effects: The water tank structure for cleaning equipment disclosed in this application improves upon related technologies. It utilizes a fan to provide negative pressure suction to the flow channel of the cover and the dirt collection area of ​​the tank. First, the solid-liquid-gas mixture of dirt is transported to the dirt collection area through the suction port of the tank. Gas and a small amount of wastewater in the dirt further enter the flow channel through the first opening. Under the shielding effect of the baffle, the wastewater in the dirt is further intercepted, causing the wastewater to flow back to the dirt collection area. Gas is diverted through the guide holes of the baffle to the second opening and finally discharged through the exhaust port of the tank and the fan. This design enables effective separation of the solid-liquid-gas mixture of dirt in the dirt collection area and inside the flow channel, thereby preventing wastewater from being discharged through the exhaust port and fan, reducing the probability of blockage or damage to the exhaust port and fan, and thus improving the reliability and durability of the cleaning equipment.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0013] Please refer to Figures 1 to 8 This application discloses a water tank structure for a cleaning device, which can be a cleaning robot, floor scrubber, or other equipment. The water tank structure can be installed inside the cleaning device, which can collect dust particles, sewage, and other dirt from the ground into the water tank structure. At the same time, the water tank structure can also store clean water for cleaning purposes.

[0014] The aforementioned water tank structure may include a tank body 110, a cover 120, and a separation filter assembly 130. The tank body 110 has a dirt collection area 111 inside. The side wall of the tank body 110 is provided with a suction port 112 and an exhaust port 113. The suction port 112 is connected to the dirt collection area 111 and can be used to transfer dirt collected by the external cleaning component 140 to the dirt collection area 111. The external cleaning component 140 may be a roller brush, a bristle brush, or other components. The external cleaning component 140 can pick up solid waste and sewage from the ground. The exhaust port 113 can be connected to a blower 150. When the blower 150 is working, it can put the inside of the tank body 110 into a negative pressure state, thereby providing negative pressure suction to the suction port 112, so that the solid waste and sewage picked up by the external cleaning component 140 can be collected into the dirt collection area 111 through the suction port 112.

[0015] The cover 120 is placed over the open end of the housing 110. The cover 120 and the housing 110 can be assembled together by means of snap-fit, bolt connection, etc. The interior of the cover 120 is provided with a flow channel 121, which has a first opening 1211 and a second opening 1212. The first opening 1211 faces the dirt collection area 111, and the second opening 1212 is connected to the exhaust port 113. The airflow transmission path in the water tank structure is as follows: suction port 112 → dirt collection area 111 → first opening 1211 → flow channel 121 → second opening 1212 → exhaust port 113. The gas discharged from the exhaust port 113 is finally discharged by the fan 150. In the above path, some solid waste and sewage will be collected in the dirty collection area 111, and some airflow carrying sewage will be transported along the path of first opening 1211 → flow channel 121 → second opening 1212 → exhaust port 113. When it is discharged by the fan 150, it is easy to cause the fan 150 to be blocked or damaged.

[0016] To address the aforementioned issues, a separation filter assembly 130 can be installed within the flow channel 121 to block wastewater in the airflow, thereby separating the wastewater from the gas. Specifically, the separation filter assembly 130 may include a baffle 131 connected to the inner wall of the flow channel 121. The connection method can be snap-fit, heat-fusion connection, or bonding. The baffle 131 has a guide hole 1311. The solid portion of the baffle 131 is positioned opposite to the first opening 1211. When the airflow carrying wastewater passes through the first opening 1211, it is blocked by the solid portion of the baffle 131, thus separating the wastewater from the gas under the obstruction of the baffle 131. The guide hole 1311 connects the first opening 1211 and the second opening 1212. The separated gas can be transmitted through the guide hole 1311, the second opening 1212, and the exhaust port 113 to the fan 150, and then discharged by the fan 150. Since the baffle 131 can effectively reduce the amount of sewage carried in the airflow, it can reduce the probability of the blower 150 becoming clogged or damaged.

[0017] As described above, the water tank structure for cleaning equipment disclosed in this application improves upon related technologies. It utilizes a fan 150 to provide negative pressure suction to the flow channel 121 of the cover 120 and the dirt collection area 111 of the box 110. The dirt, which is a mixture of solid, liquid, and gas, is first transported to the dirt collection area 111 through the suction port 112 of the box 110. The gas and a small amount of sewage in the dirt will further enter the interior of the flow channel 121 through the first opening 1211. Under the shielding effect of the baffle 131, the sewage in the dirt can be further intercepted, causing the sewage to flow back to the dirt collection area 111. The gas is diverted to the second opening 1212 through the guide hole 1311 of the baffle 131, and finally discharged through the exhaust port 113 of the box 110 and the fan 150. The above design enables the solid, liquid and gaseous mixture of dirt to be well separated in the dirt collection area 111 and the flow channel 121, thereby preventing sewage from being discharged through the exhaust port 113 and the blower 150, reducing the probability of blockage or damage to the exhaust port 113 and the blower 150, and thus improving the reliability and durability of the cleaning equipment.

[0018] The cover 120 can be a one-piece structure or a split structure. In an optional embodiment of this application, to facilitate the assembly of the cover 120, the cover 120 may include a top cover 122 and a bottom shell 123. The top cover 122 is connected to the bottom shell 123 and forms the aforementioned flow channel 121. The top cover 122 covers the open end of the housing 110. At least a portion of the bottom shell 123 extends into the dirt collection area 111, and the baffle 131 is connected to the inner wall of the bottom shell 123. The connection method between the top cover 122 and the bottom shell 123 can be snap-fit, adhesive, etc. Similarly, the connection method between the baffle 131 and the bottom shell 123 can also be snap-fit, adhesive, etc.

[0019] The first opening 1211 is formed on the bottom wall of the bottom shell 123, and the second opening 1212 is formed on the side wall of the bottom shell 123. A first flow gap exists between the baffle 131 and the bottom wall of the bottom shell 123. The first opening 1211 communicates with the guide hole 1311 through the first flow gap. A second flow gap exists between the baffle 131 and the top cover 122. The guide hole 1311 communicates with the second opening 1212 through the second flow gap. Under the action of the baffle 131, the amount of sewage carried in the airflow can be effectively reduced, thereby reducing the probability of blockage or damage to the blower 150.

[0020] The aforementioned separation and filtration assembly 130 may further include a baffle 132, which is disposed in the second flow gap. The baffle 132 can be connected to the top cover 122. The baffle 132 and the top cover 122 can be an integral structure or manufactured separately and then assembled together by means of bonding, snap-fitting, etc. Some sewage may still remain in the airflow flowing into the second flow gap through the guide hole 1311. By setting the baffle 132, the sewage can be further intercepted, thereby further reducing the sewage carried in the airflow.

[0021] Considering that the sewage intercepted by the baffle 132 will form large droplets after a long period of accumulation, a guide slope 1312 can be provided on the side of the baffle 131 near the top cover 122 to facilitate droplet collection. The guide slope 1312 forms a preset angle with the horizontal plane, which can be in the range of 5°-30°, specifically 5°, 10°, 15°, 30°, etc. The baffle 132 and the guide slope 1312 are arranged opposite each other, and the sewage collected on the baffle 132 will drip onto the guide slope 1312 for collection.

[0022] In order to discharge the sewage on the guide slope 1312 in a timely manner, a valve body 1313 can be provided at the bottom of the guide slope 1312. The valve body 1313 is unidirectionally open from the baffle 131 to the bottom shell 123. The sewage collected on the guide slope 1312 can flow through the valve body 1313 to the bottom shell 123, and then further flow through the first opening 1211 to the dirty collection area 111.

[0023] In an optional embodiment of this application, the separation filter assembly 130 may further include a partition plate 133 and a cover plate 134. The partition plate 133 is connected to the side of the baffle 131 facing away from the bottom shell 123, and the cover plate 134 covers the partition plate 133. The cover plate 134, the partition plate 133, and the baffle 131 form a vortex channel 135. A guide hole 1311 is located at the inlet end of the vortex channel 135, and the cover plate 134 is provided with a through hole 1341 located at the outlet end of the vortex channel 135. The guide hole 1311 communicates with the second opening 1212 through the vortex channel 135 and the through hole 1341. The airflow flows into the vortex channel 135 through the guide hole 1311 and then exits through the through hole 1341 and the second opening 1212. Since the airflow is subjected to centrifugal force when it flows in the vortex channel 135, the sewage carried in the airflow will adhere to the partition plate 133 under the action of centrifugal force, thereby further reducing the sewage carried in the airflow.

[0024] The aforementioned partition plate 133 may include a first vortex segment 1331, a second vortex segment 1332, and a third vortex segment 1333 arranged sequentially along the vortex trajectory. The diameters of the first vortex segment 1331, the second vortex segment 1332, and the third vortex segment 1333 gradually decrease. The end of the first vortex segment 1331 and the beginning of the second vortex segment 1332 are spaced apart to form a first diversion channel 1334. The end of the second vortex segment 1332 and the beginning of the third vortex segment 1333 are spaced apart to form a second diversion channel 1335. The area enclosed by the third vortex segment 1333 is opposite to the through hole 1341. The baffle plate 131 is provided with a drain outlet 1314. The first diversion channel 1334 is connected to the first flow gap through the drain outlet 1314.

[0025] When the airflow flows in the vortex channel 135, the wastewater carried in the airflow adheres to the separator plate 133 under the action of centrifugal force. By setting the first diversion channel 1334, the wastewater can enter the first diversion channel 1334, and then the wastewater will be discharged to the bottom shell 123 through the drain outlet 1314, and then further transferred to the dirt collection area 111 through the first opening 1211. The second diversion channel 1335 can transfer the airflow back to the first vortex section 1331 for further separation, thereby improving the separation effect.

[0026] In one optional embodiment of this application, the bottom shell 123 has an extension channel 1231 inside. The first port of the extension channel 1231 communicates with the suction port 112, and the second port of the extension channel 1231 extends into the dirt collection area 111 and is close to the bottom wall of the housing 110. Dust particles, sewage and other dirt are discharged to the bottom of the housing 110 after passing through the suction port 112 and the extension channel 1231, which can reduce dirt splashing.

[0027] The aforementioned housing 110 also has a clean water storage area 114 inside, and a spray nozzle 1232 is provided in the extension channel 1231. The spray nozzle 1232 is connected to the clean water storage area 114. A water pump can be used to draw clean water from the clean water storage area 114 and transfer it to the spray nozzle 1232. The spray nozzle 1232 is used to clean the extension channel 1231 and the dirt collection area 111, which can prevent dirt from adhering to the extension channel 1231 and the dirt collection area 111.

[0028] To prevent large particles of debris in the dirt collection area 111 from entering the flow channel 121, a porous filter medium 160, such as a stainless steel filter screen, filter grid, or sponge, can be installed at the first opening 1211. Similarly, a porous filter medium 160 can also be installed at the second opening 1212 to prevent large particles of debris from entering the fan 150 and causing blockage.

[0029] To improve the ease of use of the cleaning equipment, a cleaning port 170 can be provided in the housing 110. The dirt collection area 111 is connected to the cleaning port 170. The cleaning port 170 can be connected to the sewage suction pipe of the base station. The sewage suction pipe generates negative pressure suction in the dirt collection area 111 and the flow channel 121 through the cleaning port 170, thereby sucking out the debris in the dirt collection area 111 and the flow channel 121, realizing the collection of debris, and also realizing simple cleaning of the dirt collection area 111 and the flow channel 121.

[0030] This application also discloses a cleaning device, which may include a device body and the aforementioned water tank structure, with the water tank structure installed inside the device body.

[0031] As described above, the water tank structure for cleaning equipment disclosed in this application improves upon related technologies. It utilizes a fan 150 to provide negative pressure suction to the flow channel 121 of the cover 120 and the dirt collection area 111 of the box 110. The dirt, which is a mixture of solid, liquid, and gas, is first transported to the dirt collection area 111 through the suction port 112 of the box 110. The gas and a small amount of sewage in the dirt will further enter the interior of the flow channel 121 through the first opening 1211. Under the shielding effect of the baffle 131, the sewage in the dirt can be further intercepted, causing the sewage to flow back to the dirt collection area 111. The gas is diverted to the second opening 1212 through the guide hole 1311 of the baffle 131, and finally discharged through the exhaust port 113 of the box 110 and the fan 150. The above design enables the solid, liquid and gaseous mixture of dirt to be well separated in the dirt collection area 111 and the flow channel 121, thereby preventing sewage from being discharged through the exhaust port 113 and the blower 150, reducing the probability of blockage or damage to the exhaust port 113 and the blower 150, and thus improving the reliability and durability of the cleaning equipment.

[0032] This application also discloses a cleaning system, which includes a base station and the aforementioned cleaning equipment. The base station has a housing, and the cleaning equipment can dock inside the housing to perform operations such as sewage discharge, cleaning, and charging. The cleaning system disclosed in this application has the same beneficial effects as the aforementioned cleaning equipment, and will not be described in detail here.

[0033] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
