[0002] Existing cleaning devices, such as carpet cleaners, mainly consist of a base, body, rear seat, and functional components such as a wastewater tank and a clean water tank. The base, as the key component in contact with the ground, integrates the body and rear seat, which are secured and supported by a snap-fit ​​structure. The base also houses the wastewater tank and clean water tank; the wastewater tank collects wastewater generated during the cleaning process. To ensure stable installation of the wastewater and clean water tanks, existing products have relatively complex structures and operations, requiring users to press release buttons to remove either tank. While this structure achieves basic functionality, it suffers from large size and cumbersome operation, affecting ease of use and space utilization. Therefore, there is an urgent need for a carpet cleaner design with a more compact structure, easier assembly and disassembly, and the ability to install and remove the wastewater tank without complex operations, thereby improving user experience and product practicality.

[0041] Existing cleaning devices, such as carpet cleaners, typically include a base, main body, rear seat, and functional components such as a wastewater tank and a clean water tank. The base, which contacts the ground, integrates the main body and rear seat, and is secured with a snap-fit ​​mechanism. The wastewater and clean water tanks are located on the base and are used to collect wastewater and store cleaning solutions. To ensure stable tank installation, the existing structure and operation are relatively complex, requiring the pressing of a button to disassemble the tank. This results in issues such as large size and cumbersome operation, affecting ease of use and space utilization.

[0042] This utility model proposes a cleaning device 100, which aims to solve the problems of existing cleaning devices being cumbersome to operate and bulky when picking up and placing clean water tanks and wastewater tanks.

[0043] Please see Figures 1 to 3 In one embodiment of the present invention, the cleaning device 100 includes a base 1, two water tanks 2 and a body 3; the two water tanks 2 are installed on the top of the base 1; the body 3 extends vertically and the lower end of the body 3 is rotatably connected to the base 1; wherein, the base 1 is provided with an installation structure 4, the installation structure includes an installation housing 41 and two retaining parts 42 at least partially disposed within the installation housing 41, each water tank 2 is provided with a mating part 20, the retaining part 42 and the mating part 20 of the corresponding water tank 2 are engaged and connected, so that each water tank is installed on the base.

[0044] It should be noted that the base 1 is the part of the cleaning device 100 that contacts the ground, supporting the two water tanks 2 and enabling the spraying of cleaning liquid and the recycling of wastewater. The base 1 can be used as a floor brush for spraying cleaning liquid, scrubbing, and recycling wastewater. The base 1 may have a brush roller mounting cavity, a suction channel, and a spray nozzle inside, and brush bristles or a cleaning surface on the outer bottom surface for cleaning carpets or hard floors. The structural form and functional integration of the base 1 can refer to existing floor brush designs, and are not limited to roller brush, vibrating, or reciprocating structures. This specification does not limit this aspect in the embodiments.

[0045] Two water tanks 2 are respectively installed on the top of the base 1. The first water tank 201 is used to store clean water for cleaning, and the second water tank 202 is used to collect wastewater generated during the cleaning process. The first water tank 201 is provided with a first mating part, and the second water tank 202 is provided with a second mating part, which are respectively used to mate with the mounting structure 4 on the base 1 to realize the detachable connection of the water tanks.

[0046] The mounting structure 4 is mounted on the base 1 and includes a mounting housing 41 and two retaining parts 42, at least partially disposed inside the mounting housing 41. The two retaining parts 42 correspond to the first water tank 201 and the second water tank 202, respectively; that is, the first retaining part corresponds to the first mating part of the first water tank 201, and the second retaining part corresponds to the second mating part of the second water tank 202. When the water tank 2 is placed on the base 1, under the action of gravity or slight pressure, the mating part 20 on the water tank 2 can automatically engage with the retaining part 42, thereby quickly fixing the water tank 2. When it is necessary to remove the water tank 2, the user only needs to lift the water tank 2 upwards to disengage the mating part 20 from the retaining part 42, thus completing the quick disassembly of the water tank 2.

[0047] The body 3 extends vertically, and its lower end is connected to the base 1 via a rotatable connection. When the user needs to remove or place the water tank 2, the body 3 can be rotated to avoid the path of the water tank 2, thereby preventing the body 3 from interfering with the disassembly and assembly of the water tank 2.

[0048] In actual use, before starting the cleaning operation, the user usually needs to install the first water tank 201 onto the base 1 to ensure that the cleaning device 100 has sufficient cleaning fluid for spraying and cleaning. After the cleaning operation is completed, the user can remove the first water tank 201 for cleaning or refilling. As for the second water tank 202, the user usually continuously collects wastewater during the cleaning process. When the second water tank 202 is close to full or after completing a cleaning task, it needs to be removed for wastewater emptying and internal cleaning. At this time, the user only needs to lift the second water tank 202 upwards to separate it from the base 1. The operation is simple and requires no additional tools or complicated steps.

[0049] By providing two locking parts 42 within the mounting housing 41, which respectively engage with the mating parts 20 of the first water tank 201 and the second water tank 202, the water tank 2 can automatically lock and secure itself during placement using its own weight or slight pressure, eliminating the need for additional operations and simplifying the installation process. Furthermore, when disassembling the water tank 2, the user only needs to pull it upwards to detach it, without pressing buttons or other complex operations, thus enhancing convenience.

[0050] Further, please refer to Figure 1 In this embodiment, the two water tanks 2 are arranged side by side in the front-to-back movement direction of the cleaning device.

[0051] It should be noted that the "forward and backward movement direction" refers to the main direction of movement of the cleaning device 100 when the user pushes or guides it forward and backward while performing a cleaning task; that is, the direction in which the cleaning device 100 moves relative to the ground during cleaning operations. This direction is consistent with the extension direction of the base 1 and the cleaning path of the base structure. When the user operates the cleaning device 100 to clean carpets or floors, by pushing the body 3 to move it forward or backward in a straight line, the direction formed by this movement trajectory is the forward and backward movement direction.

[0052] In this direction, the first water tank 201 and the second water tank 202 are arranged sequentially in the front-to-back direction and are close to each other in the lateral space, forming a compact parallel structure. Specifically, the first water tank 201 can be located at the front and the second water tank 202 at the rear, or vice versa, the first water tank 201 and the second water tank 202 can be installed side by side on the top of the base 1, making full use of the structural space of the cleaning device 100 in the front-to-back direction. Since the two water tanks 2 are arranged side by side in the front-to-back direction, the user can operate independently from the front or the rear when installing or removing the water tanks 2, without interfering with each other.

[0053] Specifically, please refer to Figure 2 In this embodiment, the body 3 includes a main body 31 and two side parts 32. The two side parts 32 are respectively disposed on both sides of the main body 31 and extend downward from the main body 31. The lower ends of the two side parts 32 are respectively rotatably connected to the two opposite side parts of the base 1. The main body 31 and the two side parts 32 define an accommodating space a between the main body 31 and the base 1, and at least a portion of at least one water tank 2 is located in the accommodating space a.

[0054] It should be noted that the main body 31 constitutes the central main structure of the fuselage 3, used for user grip and integration of control components, power supply, or piping systems. Two side sections 32 are respectively located on the left and right sides of the main body 31, extending downwards from the lower part of the main body 31 in a vertical direction, forming a symmetrical support arm structure. The lower ends of the two side sections 32 are rotatably connected to two opposite sides of the base 1, i.e., the left and right sides of the base 1 arranged opposite each other in the horizontal direction, thereby achieving multi-point hinge between the fuselage 3 and the base 1.

[0055] With this connection method, the body 3 can rotate around the rotation axis relative to the base 1 at a certain angle, which makes it convenient for the user to rotate the body 3 to clear the access path when maintaining or replacing the water tank 2.

[0056] Specifically, the main body 31, the two side portions 32, and the base 1 together spatially define the receiving space a. This receiving space a is located in the inner region of the fuselage 3 and is formed by the rear of the main body 31, the inner walls of the two side portions 32, and the top of the base 1.

[0057] Please see Figure 1 In the accommodating space a, at least one water tank 2 is disposed therein. Specifically, at least a portion of at least one of the first water tank 201 or the second water tank 202 is arranged within the accommodating space a, or both water tanks 2 can be at least partially accommodated within the space, thereby achieving integration of the water tank with the body structure. This arrangement can fully utilize the internal space between the body 3 and the base 1, thereby avoiding the volume expansion problem caused by placing the water tank outside the whole machine.

[0058] Specifically, please refer to Figures 3 to 5 In this embodiment, each of the two water tanks 2 has a mating part 20 on its first side that is close to each other, and the mating part 20 of each water tank 2 is detachably connected to a corresponding holding part 42.

[0059] Specifically, when the first water tank 201 and the second water tank 202 are arranged side by side along the front-to-back movement direction of the cleaning device 100, they are close to each other in the lateral direction, and their adjacent side surfaces are defined as "first side surfaces". On the two first side surfaces, there are respectively provided mating parts 20 for cooperating with the holding parts 42 on the base 1, wherein the first mating part of the first water tank 201 is detachably connected to the corresponding first holding part on the base 1, and the second mating part of the second water tank 202 is detachably connected to the second holding part.

[0060] The mating part 20 is preferably a groove, buckle, or limiting protrusion structure provided on the side of the water tank 2. Its shape matches the holding part 42, and it can automatically engage with the water tank 2 by gravity or by applying downward pressure when the water tank 2 is placed on the base 1. When it is necessary to disassemble the water tank 2, the user only needs to lift the water tank 2 upward to disengage the mating part 20 from the holding part 42, which can achieve quick disassembly.

[0061] By placing the mating part 20 on the first side of the two water tanks 2 that are close to each other, the two water tanks 2 can fit tightly together in the installed state, which not only reduces the occupancy of the lateral space, but also enhances the compactness of the overall structure.

[0062] Furthermore, since the first sides of the two water tanks 2 are close to each other, users do not need to pay extra attention to the gap between the water tanks 2 during operation, thus achieving stable installation and sealed connection.

[0063] Specifically, please refer to Figures 5 to 7 In this embodiment, the mating part 20 includes a mating groove 2a disposed on the first side of the corresponding water tank 2, with the groove opening of the mating groove 2a facing downward; the holding part 42 is movably mounted on the mounting housing 41 in the vertical direction, for extending into the corresponding mating groove 2a and engaging with the mating groove 2a in a limiting fit.

[0064] Specifically, the mating groove 2a is formed in the middle or lower part of the first side of the water tank 2 that are close to each other, and its shape is preferably a groove structure with a certain depth, which is used to form a limiting fit with the holding part 42.

[0065] The retaining part 42 is movably installed within the mounting housing 41 in the vertical direction. Its structure can be a snap-fit ​​driven by an elastic element, a sliding pin, or an elastic arm structure with a limiting function. When the water tank 2 is placed on the base 1, the retaining part 42 is initially located at a higher position within the mounting housing 41, at which point there is a gap between the retaining part 42 and the mating groove 2a. As the water tank 2 moves downward, the lower edge of the mating groove 2a pushes the retaining part 42 downward until the retaining part 42 is aligned and extends into the interior of the mating groove 2a, achieving a limiting connection.

[0066] This design allows the water tank 2 to be automatically engaged during installation simply by placing it vertically downwards, without requiring additional alignment or rotation. For disassembly, the user only needs to lift the water tank 2 upwards to disengage the retaining part 42 from the mating groove 2a, enabling quick removal.

[0067] Furthermore, since the groove opening of the mating groove 2a faces downward, the holding part 42 can limit the water tank 2 in the front-back direction after it is engaged in the mating groove 2a, preventing the water tank 2 from sliding or shifting during the front-back movement of the cleaning device 100.

[0068] Specifically, please refer to Figure 5 In this embodiment, the mounting structure 4 further includes two elastic members 43, each elastic member 43 connecting the mounting housing 41 and the corresponding retaining part 42, so that the corresponding retaining part 42 can be extended and retracted in the vertical direction.

[0069] Specifically, the two elastic members 43 include a first elastic member and a second elastic member, wherein the first elastic member connects the mounting housing 41 and the first holding part, and is used to drive the first holding part to reciprocate in the vertical direction relative to the mounting housing 41; the second elastic member connects the mounting housing 41 and the second holding part, and is used to drive the second holding part to achieve the same elastic action.

[0070] Each elastic element 43 is preferably a compression spring, a torsion spring, or a plastic elastic arm structure with elasticity. One end of the elastic element is fixed to the support structure inside the mounting housing 41, and the other end acts on the force-bearing part of the corresponding holding part 42.

[0071] This design allows the elastic element to effectively buffer the engagement of the retaining part 42 during its contact with the mating groove 2a, preventing rigid collisions between the first retaining part and the first mating part of the first water tank 201, and also preventing hard contact between the second retaining part and the second mating part of the second water tank 202. When the user quickly installs the water tank 2, the elastic element 43 effectively absorbs impact energy, protecting the mating structure from damage.

[0072] Specifically, please refer to Figure 3 and Figure 4 In one embodiment, the first side of the water tank 2 is recessed with a groove penetrating the bottom of the water tank 2, and the first side wall above the groove is provided with a limiting protrusion 21, which defines a mating groove 2a between the limiting protrusion 21 and the inner wall of the groove; the side of the holding part 42 facing the other holding part 42 is recessed with a limiting groove 42a penetrating its top, and the limiting groove 42a is matched with the limiting protrusion 21.

[0073] Because the retaining part 42 has a recessed limiting groove 42a extending through its top on the side facing the other retaining part 42, and the opening of the limiting groove 42a faces the other retaining part 42, the limiting groove 42a and the limiting protrusion 21 form a limiting engagement after the water tank 2 is installed in place. Specifically, when the water tank 2 is placed vertically downwards onto the base 1, the retaining part 42 automatically extends into the engaging groove 2a, and at the same time, the limiting protrusion 21 also enters the limiting groove 42a. The two mutually limit each other in the front-back direction, preventing the water tank 2 from shifting or shaking during the front-back movement of the cleaning device 100.

[0074] Furthermore, the mating surfaces of the limiting protrusion 21 and the limiting groove 42a can preferably be inclined or rounded transition structures, thereby guiding the limiting protrusion 21 and the limiting groove 42a to align smoothly and enter the limiting state during installation. This not only improves the smoothness of water tank 2 installation but also enhances the stability of the limiting fit. In addition, since the limiting groove 42a penetrates the top of the retaining part 42, the limiting protrusion 21 can smoothly enter the limiting groove 42a from top to bottom during water tank 2 installation without additional angle or direction adjustments, further improving installation convenience.

[0075] Further, please refer to Figure 4 In this embodiment, guide slopes 421 are provided on the opposite sides of the two holding parts 42.

[0076] Specifically, each holding part 42 has an inclined guide slope 421 on its side surface facing away from the other holding part 42. The guide slope 421 gradually extends outward from the top to the bottom of the holding part 42 to form a guide entrance structure.

[0077] The guide ramp 421 provides progressive guidance for the water tank 2 during downward installation, enabling it to automatically adjust its position when it contacts the holding part 42, thereby reducing installation resistance. This not only improves the smoothness and fault tolerance of the water tank 2 installation, but also effectively avoids problems such as jamming and misalignment caused by improper installation angle or inaccurate alignment.

[0078] Specifically, please refer to Figure 5 In this embodiment, the mounting housing 41 has a receiving cavity 41a, and the top of the receiving cavity 41a is provided with an opening 41b. The holding part 42 is installed in the receiving cavity 41a and passes through the opening 41b. The peripheral side of the holding part 42 is provided with a limiting stop part 422, which is used to cooperate with the inner peripheral edge of the opening 41b when the holding part 42 moves outward toward the opening 41b.

[0079] It should be noted that the limiting stop 422 is preferably a flange structure extending outward from the outer periphery of the holding part 42, and its position is located between the upper and lower ends of the holding part 42. When the holding part 42 moves in the receiving cavity 41a in the vertical direction, the limiting stop 422 moves synchronously with the holding part 42, and when the holding part 42 moves upward to the limit position, it forms a limiting stop engagement with the inner periphery of the opening 41b.

[0080] Specifically, when the water tank 2 is removed or subjected to an upward external force, the retaining part 42 moves upward under the push of the elastic member 43, and the limiting stop part 422 rises accordingly until it contacts the inner edge of the opening 41b and stops, thereby preventing the retaining part 42 from completely detaching from the mounting housing 41. This arrangement ensures that the retaining part 42 is always retained in the receiving cavity 41a, preventing the retaining part 42 from falling off due to misoperation or vibration.

[0081] Further, please refer to Figure 8 and Figure 9 In this embodiment, one of the water tank 2 and the base 1 is provided with a positioning protrusion 22, and the other is provided with a positioning groove 1a that is positioned and engaged with the positioning protrusion 22.

[0082] Specifically, the positioning protrusion 22 can be provided at the bottom or side of the water tank 2, while the positioning groove 1a is correspondingly provided on the mounting area of ​​the base 1 for supporting the water tank 2. When the water tank 2 is placed on the base 1, the positioning protrusion 22 is inserted into the positioning groove 1a, thereby achieving the initial alignment and positioning between the water tank 2 and the base 1.

[0083] The preferred positioning structure consists of multiple positioning protrusions 22 located at the bottom of the water tank 2, with corresponding multiple positioning grooves 1a located on the top mounting surface of the base 1. The engagement between the positioning protrusions 22 and the positioning grooves 1a can be an interference fit, a clearance fit, or a guide fit, designed specifically according to actual assembly requirements. During the downward placement of the water tank 2, the positioning protrusions 22 first contact the positioning grooves 1a and guide the water tank 2 into the correct installation position, thereby ensuring accurate engagement between the water tank 2 and the retaining part 42.

[0084] Furthermore, the cooperation between the positioning protrusion 22 and the positioning groove 1a not only limits the horizontal movement of the water tank 2 during installation, but also enhances the structural stability of the water tank 2 after installation to a certain extent. When the cleaning device 100 moves back and forth or is subjected to bumpy operations, it prevents the water tank 2 from shifting laterally or rotating, thereby improving the reliability and safety of the water tank 2 during use.

[0085] In addition, the positioning structure can work in conjunction with the snap-fit ​​structure between the holding part 42 and the mating groove 2a to achieve dual fixation of the water tank 2. That is, the positioning structure first achieves alignment guidance, and then the snap-fit ​​structure achieves a firm connection, thereby further improving the stability of the water tank 2 installation.

[0086] Specifically, in this embodiment, the body 3 has an upright state extending in the vertical direction and an operating state that is inclined relative to the base 1. When the body 3 is in the upright state, at least one of the two water tanks 2 can be detached from the base 1.

[0087] It should be noted that the body 3 has two position states during its rotation stroke: one is an upright state extending in the vertical direction, and the other is an operating state in which it is tilted relative to the base 1. When the cleaning device 100 is in a non-operating state, such as when it is stationary, in standby mode, self-cleaning, or charging, the body 3 is in an upright state. At this time, the body 3 is upright above the base 1 and extends in the vertical direction.

[0088] In this upright position, at least one of the two water tanks 2 can be detached from the base 1. Specifically, since the body 3 is in a vertical position, the user can directly lift either water tank 2 upwards to disengage the locking part 42 from the mating part 20, thereby completing the disassembly operation. This process does not require rotating the body 3 beforehand to avoid obstacles, making the operation process simpler.

[0089] In operation, the body 3 tilts forward relative to the base 1. The user holds the body 3 and applies force to push the cleaning device 100 forward, and the base 1 contacts the ground to perform the cleaning task.

[0090] This manual does not limit the specific structure of the rotatable connection between the body 3 and the base 1. It can be a hinge shaft, pivot pin, or universal joint structure, etc., and is not limited here. The angle difference between the upright state and the working state can be adjusted according to ergonomics or spatial layout, and the embodiments in this manual do not limit this.
