[0040] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or device comprising a series of elements not only includes those elements but also other elements not expressly listed, or elements inherent to such commodity or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the commodity or device comprising said element.

[0041] In the related art, inside a cleaning device, a clean water tank and a sewage tank are generally arranged on a handheld rod, occupying a relatively large space, which is not conducive to user storage. Moreover, since the weight of the handheld rod is increased, the user needs to apply a relatively large holding force during the use of the cleaning device, which is not conducive to convenient operation. In addition, in the related art, since the sewage tank is arranged at a relatively high position, the negative pressure assembly needs to consume a relatively large power to suck dirt into the sewage bucket. Therefore, there is also a problem of excessive noise of the negative pressure assembly in the related art, which affects the user experience.

[0042] An embodiment of the present disclosure provides a cleaning device having a cleaning head assembly and a handheld rod connected to each other, including: a cleaning member arranged on the cleaning head assembly for cleaning an operation surface; a clean water tank configured to provide clean water for the cleaning member; and a sewage tank arranged inside the cleaning head assembly for collecting dirt generated by the cleaning member, shortening the distance for the dirt to enter the sewage tank.

[0043] In the cleaning device provided by the present disclosure, the sewage tank is arranged on the cleaning head assembly, which reduces the weight of the handheld rod and increases the gravity of the cleaning head assembly at the same time. On the one hand, it shortens the distance for the dirt on the cleaning member to enter the sewage tank, and on the other hand, it makes it easier for the user to clean the operation surface when using the cleaning device, improving the user experience.

[0044] In view of this, the optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0045] An embodiment of the present disclosure provides a cleaning device 1000, the cleaning device 1000 having a cleaning head assembly 100 and a handheld rod 200 connected to each other. The cleaning head assembly 100 is configured to clean an operation surface, and when the cleaning head assembly 100 contacts the operation surface, dust and stains on the operation surface can be cleaned up together. The cleaning head assembly 100 has a connecting portion configured to be rotatably connected to the handheld rod 200.

[0046] In some embodiments, the cleaning device 1000 includes a cleaning member 130, a clean water tank 110, and a sewage tank 120. The cleaning member 130 is disposed inside the cleaning head assembly 100 and at least partially contacts the operation surface, configured to drive the cleaning head assembly 100 to move on the operation surface to clean the operation surface. The cleaning member 130 can be a roller brush, a mop, a mop board, etc.

[0047] The clean water tank 110 is configured to provide clean water for the cleaning member 130. Specifically, a clean water pump 111 can also be disposed inside the cleaning head assembly 100. The clean water in the clean water tank 110 is pumped to the cleaning member 130 through the clean water pump 111, so that the cleaning member 130 cleans the operation surface. The sewage tank 120 is disposed inside the cleaning head assembly 100 and is configured to collect the dirt generated by the cleaning member 130. When the sewage tank 120 is disposed inside the cleaning head assembly 100, the distance for the dirt to enter the sewage tank 120 can be shortened, the cleaning speed of the cleaning member 130 can be increased, and the noise generated during dirt collection can be reduced. Among them, the dirt includes sewage and impurities entrained in the sewage, such as dust, hair and other impurities.

[0048] In some embodiments, as Figure 2 shown, a cleaning liquid assembly 150 is further disposed inside the cleaning head assembly 100. The cleaning liquid assembly 150 includes a cleaning liquid tank and a cleaning liquid pump. The cleaning liquid pump is used to pump the cleaning liquid in the cleaning liquid tank to the cleaning member 130 to clean the cleaning member 130. The cleaning liquid assembly 150 is disposed inside the cleaning head assembly 100, which can further reduce the weight of the handheld rod 200.

[0049] In some embodiments, a water injection port is provided on the side wall of the clean water tank 110 for injecting clean water into the clean water tank 110. The clean water tank 110 further includes a clean water tank 110 sealing cover matching the water injection port for ensuring the sealing performance of the water injection port and avoiding liquid leakage. A water outlet is provided on the side wall of the sewage tank 120 for pouring the sewage in the sewage tank 120. The sewage tank 120 further includes a sewage tank 120 sealing cover matching the water outlet for ensuring the sealing performance of the water outlet and avoiding liquid leakage.

[0050] The sewage tank 120 is used to store the sewage generated by cleaning the cleaning member 130. A sealing ring is provided at the water outlet of the sewage tank 120, configured to enable the sewage tank 120 to be hermetically installed inside the cleaning head assembly 100, avoid sewage leakage, and ensure the airtightness inside the sewage tank 120.

[0051] In some embodiments, the cleaning device 1000 further includes a negative pressure assembly 300 and a battery module 400. The negative pressure assembly 300 and the battery module 400 are detachably disposed on the handheld rod 200 and configured to provide suction for the sewage tank 120 to suck the sewage generated by the cleaning member 130 cleaning the operation surface into the sewage tank 120. The battery is configured to provide energy for components such as the negative pressure assembly 300 and the water pump 111. Specifically, the water tank 110 pumps clean water towards the cleaning member 130 to clean the operation surface. In response to the cleaning member 130 cleaning the operation surface, the dust on the operation surface is absorbed by the cleaning member 130 and combines with the clean water on the cleaning member 130 to generate sewage. Further, the battery module provides power for the negative pressure assembly 300, and the negative pressure assembly 300 generates a high-speed air flow to form a negative pressure in the sewage tank 120. The sewage generated after the cleaning member 130 cleans the operation surface enters the sewage tank 120 under the action of the negative pressure. Since the sewage tank 120 is disposed in the cleaning head assembly 100, the sewage collection path from the cleaning member 130 to the sewage tank 120 is shortened. At this time, the suction force required by the negative pressure assembly 300 is reduced, thereby reducing the noise generated by the negative pressure assembly 300 during use. At the same time, the power consumption of the negative pressure assembly 300 is reduced, which is beneficial to energy conservation and emission reduction and prolongs the service life of the negative pressure assembly 300.

[0052] In some embodiments, the sewage tank 120 includes an air outlet, a sewage inlet, and a partition 121. The air outlet is communicated with the negative pressure assembly 300, and the sewage inlet is communicated with the sewage collection pipeline and is configured to convey sewage from the sewage inlet into the sewage tank 120 under the negative pressure of the negative pressure assembly 300. The partition 121 is disposed between the air outlet and the sewage inlet and divides the sewage tank 120 into a first chamber 101 and a second chamber 102, and is configured to extend the flow path of the dirt in the sewage tank 120 to prevent the sewage path from being blocked due to excessive dirt, so that all the sewage cannot be sucked into the sewage tank 120, resulting in sewage residue at the cleaning member.

[0053] In some embodiments, at least a part of the partition 121 is a solid-liquid separation net 122, and the solid-liquid separation net 122 is configured to filter impurities. Specifically, the solid-liquid separation net 122 is disposed at one end of the partition 121 away from the air outlet and the sewage inlet. On the one hand, it prevents the impurities in the dirt from being too many and blocking the sewage flow path at the sewage inlet. On the other hand, it prevents the filtered sewage from flowing into the negative pressure assembly 300. Therefore, the solid-liquid separation net 122 is away from the air outlet and the sewage inlet.

[0054] Specifically, on both sides of the solid-liquid separation net 122 are a first chamber 101 and a second chamber 102 respectively. The solid-liquid separation net 122 enables the flow of dirt to be from the sewage inlet into the first chamber 101, and after passing through the solid-liquid separation net 122, it flows into the second chamber 102. And because the negative pressure component 300 is arranged on the hand-held rod 200, the sewage in the sewage tank 120 will not flow into the negative pressure component 300, avoiding the influence of sewage on the negative pressure component 300.

[0055] In some embodiments, to lower the center of gravity of the cleaning device 1000, the water tank 110 can also be arranged inside the cleaning head assembly 100. In the working state, the forward direction of the cleaning device is the front, and the backward direction is the rear. On both sides of the straight line where the front or the rear is located are the left direction and the right direction respectively. As Figure 1 shown, the water tank 110 and the sewage tank 120 are arranged left and right. In this way, the water tank 110 and the sewage tank 120 arranged make the gravity of the cleaning head assembly 100 relatively balanced in the left-right direction, enabling the user to more stably control the flexible rotation of the cleaning head assembly 100 when using the cleaning head assembly 100.

[0056] When both the water tank 110 and the sewage tank 120 are arranged inside the cleaning head assembly 100, the gravity of the cleaning head assembly 100 is increased. Compared with the cleaning device in which both the water tank and the sewage tank are arranged on the hand-held rod, the cleaning device 1000 provided by the embodiment of the present disclosure shortens the water supply path of the water tank 110 and also shortens the sewage collection path of the sewage tank 120. At the same time, the gravity of the cleaning head assembly 100 is increased, making the overall center of gravity of the cleaning device 1000 lower, which is beneficial to reducing the weight of the hand-held rod 200 and making the user feel more portable when using the cleaning device 1000, improving the user experience.

[0057] In some embodiments, as Figure 2 shown, the water tank 110 and the sewage tank 120 are arranged front and rear inside the cleaning head assembly 100. The water tank 110 can be arranged at one end of the cleaning head assembly 100 away from the connection part, for providing clean water for the operation surface cleaning. Specifically, a cleaning liquid component is arranged outside the water tank 110, configured to add an appropriate amount of detergent to the water tank 110 to keep the cleaning part 130 clean in the working state. The sewage tank 120 is arranged at one end of the cleaning head assembly 100 adjacent to the connection part, for accommodating the sewage generated during the working process of the cleaning device. A sewage collection pipeline is arranged between the cleaning part 130 and the sewage tank 120, configured to transport the sewage generated by the cleaning part 130 to the sewage tank 120.

[0058] It should be separately noted that the present disclosure does not specifically limit the installation positions of the clean water tank 110 and the sewage tank 120. Inside the cleaning head assembly 100, it is also possible that the clean water tank 110 is arranged on one side adjacent to the connecting part, and the sewage tank 120 is arranged between the clean water tank 110 and the cleaning member 130.

[0059] In some embodiments, as Figure 2 shown, the clean water tank 110 and the sewage tank 120 can be an integrated structure. The clean water tank 110 and the sewage tank 120 are neatly arranged in a stacked manner inside the cleaning head assembly 100 and share the same side wall. Compared with the split-type water tank, it saves more internal space of the cleaning head assembly 100.

[0060] It should be noted that the stacking method inside the cleaning head assembly 100 is not limited to this. The clean water tank 110 and the sewage tank 120 can also be arranged adjacent to each other in the width direction or the height direction of the cleaning head assembly 100. No matter in what way the clean water tank 110 and the sewage tank 120 are arranged, compared with the split clean water tank 110 and sewage tank 120, for the integrated structure of the clean water tank 110 and the sewage tank 120, there is the same side wall between them, which occupies less space and has a more stable center of gravity inside the cleaning head assembly 100.

[0061] In some embodiments, as Figure 3 shown, the clean water tank 110 and the sewage tank 120 can be stacked along the height direction of the cleaning head assembly 100 into the cleaning head assembly 100. Through the clean water pump 111, the clean water in the clean water tank 110 is pumped to the cleaning member 130. The sewage tank 120 is arranged adjacent to the cleaning member 130 and is configured to collect the sewage generated on the cleaning operation surface of the cleaning member 130 into the sewage tank 120 under the action of the negative pressure assembly 300. In this structure, on the one hand, the path from the cleaning member 130 to the sewage tank 120 is shorter, which is beneficial to accelerating the sewage collection speed of the sewage tank 120 and keeping the cleaning member 130 clean. On the other hand, since the clean water tank 110 and the sewage tank 120 are stacked and arranged inside the cleaning head assembly 100, in the cleaning device 1000, the gravity of the brush head is relatively large. When the user uses the device to clean the operation surface, it is easier to control the flexible turning of the brush head. At the same time, since the sewage tank 120 is arranged in the cleaning head assembly 100 and the negative pressure assembly 300 is arranged on the handheld rod 200, the liquid level in the sewage tank 120 will not change due to the torsion of the cleaning head assembly 100, resulting in the sewage in the sewage tank 120 entering the negative pressure assembly 300, presenting the risk of water ingress into the negative pressure assembly 300. The present disclosure embodiment does not specifically limit the negative pressure assembly 300, and the negative pressure assembly 300 can be a blower.

[0062] In some embodiments, the cleaning head assembly 100 has a cleaning member 130 and an auxiliary wheel 140. The cleaning member 130 and the auxiliary wheel 140 are disposed inside the cleaning head assembly 100 and at least partially contact the operation surface. Specifically, both the cleaning member 130 and the auxiliary wheel 140 contact the operation surface and can roll on the operation surface. The cleaning head assembly 100 moves relative to the operation surface by rolling of the cleaning member 130 and the auxiliary wheel 140.

[0063] The cleaning member 130 is used to directly contact dust and stains on the operation surface to clean the operation surface. The auxiliary wheel 140 has a guiding and rolling function and is used to assist the cleaning head assembly 100 to roll on the operation surface to ensure that the cleaning head assembly 100 can clean the dust and stains on the operation surface.

[0064] In some embodiments, in the height direction of the cleaning head assembly 100, the projection of the clean water tank 110 or the sewage tank 120 covers the auxiliary wheel 140. Since the clean water tank 110 and the sewage tank 120 have a certain weight, the auxiliary wheel 140 is disposed within the projection range of the clean water tank 110 or the sewage tank 120, so that the auxiliary wheel 140 has a supporting effect on the clean water tank 110 or the sewage tank 120. When a user uses the cleaning head assembly 100 to clean the operation surface, the cleaning head assembly 100 will not tip over due to the gravity offset of the clean water tank 110 or the sewage tank 120.

[0065] In some embodiments, the position of the auxiliary wheel 140 can be set to dry the cleaning member 130, that is, the drying cleaning member 130 is provided to replace the auxiliary wheel 140. The drying cleaning member 130 is used to assist the cleaning device to quickly dry the cleaned operation surface. It should be separately noted that the operation surface is the cleaning surface of the cleaning head assembly 100, which can be a flat surface, such as the ground; or an uneven surface, such as a carpet.

[0066] In some embodiments, the cleaning head assembly includes a first accommodation space and a second accommodation space. The first accommodation space is configured to accommodate the cleaning member, so that the cleaning member can freely rotate in the first accommodation space to clean the operation surface. The second accommodation space is configured to accommodate the clean water tank and the sewage tank. Among them, the height of the first accommodation space is lower than the height of the second accommodation space.

[0067] Specifically, as Figure 3As shown, the height of the first accommodation space is H1, and the height of the second accommodation space is H2. In order to enable at least part of the cleaning member 130 to enter a narrow gap for cleaning, the height of the first accommodation space needs to be less than the height of the rear end, that is, H1 < H2. In practical applications, for example, the gap between a cabinet or a sofa and an operating surface is approximately 3 - 8 cm. Therefore, the height of the first accommodation space is less than 8 cm.

[0068] In some embodiments, the handheld rod 200 is disposed at the rear end of the cleaning head assembly 100, and the handheld rod 200 is detachably connected to the cleaning head assembly 100. After detaching the handheld rod 200, the space occupied by the cleaning device 1000 is smaller, facilitating the storage and transportation of the cleaning equipment. One end of the handheld rod 200 away from the cleaning head assembly 100 may be provided with a handheld portion for facilitating the user to hold and clean the operating surface during use.

[0069] In the embodiments of the present disclosure, the cleaning head assembly 100 has a cuboid-like structure with a relatively low center of gravity, which can ensure the stability of the cleaning device and facilitate the user to perform cleaning operations on the operating surface.

[0070] It should be noted that the present disclosure does not limit the shape of the cleaning head assembly 100. The cleaning head assembly 100 may be configured as an approximate cuboid structure, or an approximate cylindrical structure, or any other shape that can accommodate the internal stacking of the cleaning head assembly 100. When the cleaning head assembly 100 is a cuboid structure, the center of the cleaning head assembly 100 is located at the intersection of the diagonals of the cuboid; when the cleaning head assembly 100 is configured as a cylinder, the center of gravity is located at the center point of the axis of the cylinder.

[0071] In some embodiments, the handheld rod 200 is rotatably connected to the cleaning head assembly 100. Thus, there is a rotatable connection angle α between the cleaning head assembly 100 and the cleaning head assembly 100, where the angle α satisfies: 60° ≤ α ≤ 180°. Further, when α is 60°, 90°, 120°, 150°, or 180° respectively, the handheld rod 200 can be clamped relative to the cleaning head assembly 100, and at the clamped position, the handheld rod 200 does not freely rotate relative to the cleaning head assembly 100, facilitating the user to clean the operating surface.

[0072] In some embodiments, when the cleaning device is accommodated in the accommodation space, the angle between the lower surface of the cleaning device and the horizontal plane is α, 45° ≤ α ≤ 90°. Such a setting can reduce the area of the base station.

[0073] In some embodiments, when the cleaning head assembly 100 is in the working state and the angle between the handheld rod 200 and the cleaning head assembly 100 is adjusted to 180°, at this time, the cleaning head assembly 100 can clean the dust in a relatively large gap space such as under the bed or under the cabinet. Therefore, the height of the cleaning head assembly 100 is approximately 8-12 cm, that is, H2≈8-12 cm.

[0074] In some embodiments, such as Figure 2 , Figure 4 shown, the battery module 400 is detachably arranged inside the cleaning head assembly 100 and is configured to provide electric energy for the cleaning head assembly 100. The battery module 400 is arranged inside the cleaning head assembly 100, which is beneficial to increasing the gravity of the cleaning head assembly 100 and reducing the weight of the handheld rod 200, so that it is more labor-saving for the user to use the cleaning device 1000.

[0075] In the embodiments of the present disclosure, the battery module 400 can be a wireless charging module. Thus, the cleaning head assembly 100 can be used in combination with the base station 2000. In the user's use environment, there is no complicated power cord connection, which is more beautiful in space layout and more convenient in use. Further, to ensure the normal charging of the battery module 400, the surface of the cleaning head assembly 100 in contact with the base station 2000 is constructed as a flat surface for charging the battery module 400 with the base station 2000.

[0076] It should be noted that the present disclosure does not specifically limit the charging method of the cleaning device 1000. It can be wireless charging, or spring pin charging, or any other charging method, which does not affect the normal use of the cleaning device 1000.

[0077] In some embodiments, the cleaning device 1000 further includes a display screen and a main board module. The display screen is used to display the remaining power of the battery module 400, the remaining water volume in the clean water tank 110, and the sewage volume in the sewage tank 120. When the remaining power is lower than the power warning value, or the remaining water volume in the clean water tank 110 is lower than the warning value of the clean water tank 110, or the sewage volume in the sewage tank 120 reaches the warning value of the sewage tank 120. A corresponding icon will flash on the display screen to prompt the user to charge or clean the water tank in time.

[0078] In a second aspect of the embodiments of the present disclosure, a cleaning system is provided. The cleaning system includes the cleaning device 1000 provided in the first aspect of the present disclosure and a base station 2000 adapted to the cleaning device 1000. The base station 2000 has a receiving space for receiving the cleaning device 1000. When the cleaning device 1000 is received in the receiving space, the angle between the lower surface of the cleaning device 1000 and the horizontal plane is α, where 0° ≤ α ≤ 90°. Specifically, as Figure 5 shown, the cleaning device 1000 can be inclined and assembled in the base station 2000 to save the floor space of the cleaning system. At this time, the angle between the lower surface of the cleaning head assembly 100 and the horizontal plane is approximately 45°.

[0079] In some embodiments, as Figure 6 shown, to save the floor space of the cleaning system, the volume of the base can be reduced so that the side wall of the first accommodation space of the cleaning head assembly 100 contacts the bottom wall of the receiving space, so that the entire cleaning device 1000 is placed vertically in the base station 2000. At this time, the angle between the lower surface of the cleaning head assembly 100 and the horizontal plane is approximately 90°.

[0080] In some embodiments, as Figure 7 shown, to save the floor space of the cleaning system, the volume of the base can be reduced so that the lower surface of the cleaning head assembly 100 contacts the bottom wall of the receiving space, so that the entire cleaning device 1000 is placed horizontally in the base station 2000. At this time, the angle between the lower surface of the cleaning head assembly 100 and the horizontal plane is approximately 0°. In some embodiments, the base station includes a cleaning pipeline configured to clean the cleaning device 1000. In response to the cleaning device 1000 being assembled to the base station 2000, the cleaning pipeline is connected to the cleaning head assembly 100 of the cleaning device 1000. In response to the cleaning device 1000 being assembled in the receiving space of the base station 2000, the clean water tank 110 and the sewage tank 120 are docked with the base station 2000, clean water is injected into the clean water tank 110 through the water inlet of the clean water tank 110, and the sewage in the sewage tank 120 is discharged through the drain outlet of the sewage tank 120.

[0081] Since the sewage tank 120 is provided in the cleaning head assembly 100, and the negative pressure assembly 300 is provided in the handheld rod 200, therefore, whether the cleaning head assembly 100 is in the working state of cleaning the operation surface, or the cleaning head assembly 100 is in the charging state when assembled to the base station 2000, or even in the charging state within the base station 2000, the sewage in the sewage tank 120 will not be inverted into the interior of the negative pressure assembly 300 due to the torsion of the cleaning head assembly 100, thus avoiding water ingress into the negative pressure assembly 300.

[0082] In some embodiments, a magnetic attraction structure may be provided at the position where the battery module 400 matches the base, configured to attract each other when adjacent, that is, accurate positioning of the battery module 400 and the base is achieved, enabling the cleaning head assembly 100 to quickly enter the charging state.

[0083] For the specific structure, working principle, and beneficial effects of the cleaning device and cleaning system provided in the embodiments of the present disclosure, reference may be made to the cleaning device and cleaning system described in any of the foregoing embodiments, and details will not be elaborated herein.

[0084] Finally, it should be noted that the embodiments in this specification are described in a progressive manner, and the key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments may be referred to each other. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and reference may be made to the description of the method part for related parts.

[0085] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
