Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning system. Background Technology

[0002] Robotic vacuum cleaners, also known as automatic cleaning machines, smart vacuums, or robotic vacuums, are a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. With technological advancements, robotic vacuum cleaners now also include base stations, which allow them to charge and operate during cleaning.

[0003] Because the sweeper and the base station are separate structures, the sweeper cannot automatically connect its wastewater tank to the base station's wastewater trough after entering the base station. This means that the user needs to manually empty the wastewater tank into the wastewater trough, which is very inconvenient.

[0004] Therefore, there is an urgent need to design a new cleaning system to improve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning system that addresses the technical problem that the sweeper cannot automatically connect its wastewater tank to the base station's wastewater trough after entering the base station, resulting in the user having to manually empty the wastewater tank into the wastewater trough.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The cleaning system provided by this utility model includes:

[0008] A base station, comprising a body and a base plate, the base plate being disposed below the body, one side of the body forming an accommodating space with the upper surface of the base plate, and a sewage tank being disposed on the upper surface of the base plate;

[0009] A sweeper, wherein the sweeper has a built-in wastewater tank, the outlet of the wastewater tank is located on the bottom or side wall of the sweeper, and a sealing element is provided in the outlet;

[0010] A swing arm assembly is rotatably mounted on the base station in a horizontal direction. When the sweeper is located in the accommodating space, the wastewater tank corresponds to the wastewater trough. The sealing element is located within the rotational stroke range of the swing arm assembly. The swing arm assembly lifts the sealing element to connect the wastewater tank and the wastewater trough.

[0011] Once the sweeper enters the base station's storage space, the sweeper's wastewater tank is positioned corresponding to the wastewater trough. The seal is located precisely within the rotational travel range of the end of the swing arm assembly. By swinging the arm assembly, the seal is lifted, opening the outlet of the wastewater tank and discharging the wastewater into the wastewater trough. This achieves automatic discharge of wastewater from the sweeper, which is very convenient.

[0012] As a preferred embodiment of the cleaning system, one end of the swing arm assembly is connected to a drive member that drives the swing arm assembly to rotate so that the other end lifts the seal.

[0013] The swing arm assembly is driven to rotate actively by the drive component, so as to complete the lifting action of the swing arm assembly on the seal.

[0014] As a preferred embodiment of the cleaning system, a first elastic element is fitted at the pivot of the swing arm assembly, with one end of the first elastic element connected to the swing arm assembly and the other end connected to the base plate.

[0015] When the sweeper enters the base station, the pressure arm assembly rotates, causing the first elastic element to twist and store force. When the sweeper enters the base station and the swing arm assembly aligns with the seal, the elastic force of the first elastic element pushes the swing arm assembly to rotate in the opposite direction, thereby lifting the seal. The structure is simple and easy to manufacture.

[0016] As a preferred embodiment of the cleaning system, the swing arm assembly includes at least:

[0017] First arm swing;

[0018] The second swing arm has one end connected to one end of the first swing arm, and the second swing arm is set at an angle to the first swing arm;

[0019] A pivot is provided at the connection between the first swing arm, the second swing arm, or the first swing arm and the second swing arm.

[0020] The first and second swing arms are set at an angle to change the orientation of the first or second swing arm in lifting the seal, and lifting and resetting are achieved by rotating along the shaft.

[0021] As a preferred embodiment of the cleaning system, a third swing arm is provided at the end of the first swing arm away from the second swing arm. The third swing arm is set at an angle to the first swing arm, and extends in the opposite direction to the second swing arm. The extended end of the third swing arm movably lifts the seal.

[0022] The third swing arm extends upwards at an angle in the vertical direction, which makes it easier to apply an upward thrust to the seal and lift the seal more easily.

[0023] As a preferred embodiment of the cleaning system, a fourth swing arm is provided at the end of the second swing arm away from the first swing arm. The fourth swing arm and the second swing arm are arranged at an angle, and the fourth swing arm extends in the opposite direction to the first swing arm.

[0024] The fourth swing arm facilitates the installation of the drive components, makes the structure fit more tightly, and makes better use of the base station's internal space.

[0025] As a preferred embodiment of the cleaning system, the first swing arm, the second swing arm, the third swing arm, and the fourth swing arm are integrally formed.

[0026] The third swing arm is formed by bending one end of the first swing arm, and the fourth swing arm is formed by bending one end of the second swing arm.

[0027] The one-piece molded structure is sturdy and not easily deformed during use.

[0028] As a preferred embodiment of the cleaning system, the driving component includes a first drive motor, which is disposed on the base plate. The output end of the first drive motor is provided with a cam, and the outer periphery of the cam abuts against the swing arm assembly to drive the swing arm assembly to rotate.

[0029] The first drive motor drives the cam to rotate. When the cam rotates to the cam protrusion, it pushes the fourth swing arm to swing downward, that is, the swing arm assembly rotates. The third swing arm then moves upward in sync to lift the seal.

[0030] As a preferred embodiment of the cleaning system, the drive component includes a second drive mechanism, which is disposed on the base plate and has its output end connected to the rotating shaft to drive the swing arm assembly to rotate.

[0031] The second driving component drives the rotating shaft to rotate in the forward or reverse direction, so that the swing arm assembly connected to the rotating shaft rotates synchronously. The second driving component drives the swing arm assembly to rotate forward, which drives the third swing arm to rotate upward to lift the seal. The second driving component drives the swing arm assembly to rotate in the reverse direction, which drives the third swing arm to rotate downward to reset the swing arm assembly.

[0032] As a preferred embodiment of the cleaning system, a second elastic element is provided around the outer periphery of the seal, the second elastic element being located inside the water outlet and abutting against the stepped surface of the seal and the inner wall of the water outlet.

[0033] The swing arm assembly pushes the seal to rise, and the second elastic element compresses and stores force. When the sweeper moves out of the base station's storage space, the seal loses the lifting force of the swing arm assembly, and the elastic force of the second elastic element pushes the seal back to its original position, thereby sealing the outlet of the sewage tank.

[0034] The beneficial effects of this utility model are:

[0035] Once the sweeper enters the base station's storage space, the sweeper's wastewater tank is positioned corresponding to the wastewater trough. The seal is located precisely within the rotational travel range of the end of the swing arm assembly. By swinging the arm assembly, the seal is lifted, opening the outlet of the wastewater tank and discharging the wastewater into the wastewater trough. This achieves automatic discharge of wastewater from the sweeper, which is very convenient. Attached Figure Description

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0048] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0051] Because the sweeper and the base station are separate structures, the sweeper cannot automatically connect its wastewater tank to the base station's wastewater trough after entering the base station. This means that the user needs to manually empty the wastewater tank into the wastewater trough, which is very inconvenient.

[0052] To solve the above problems, combined with Figures 1-6 As shown, this embodiment provides a cleaning system, which includes a base station and a sweeping robot, such as... Figure 1 and Figure 2 As shown, the base station includes a body 100 and a base plate 200. The base plate 200 is located below the body 100. One side of the body 100 and the upper surface of the base plate 200 form an accommodating space. A sewage tank is provided on the upper surface of the base plate 200. The sweeper has a built-in sewage tank 300. The outlet of the sewage tank 300 is located at the bottom of the sweeper, and a sealing element 2 is provided inside the outlet. The sealing element 2 seals the outlet, thus sealing the sewage in the sewage tank 300.

[0053] like Figure 2and Figure 3 As shown, the cleaning system also includes a swing arm assembly 1, which is rotatably mounted on the base plate 200 in the horizontal direction. The sweeper moves and stops within the accommodating space. When the sweeper is in the accommodating space, the wastewater tank 300 corresponds to the wastewater trough. The seal 2 is located within the rotation stroke range of the swing arm assembly 1. The swing arm assembly 1 lifts the seal 2 to connect the wastewater tank 300 with the wastewater trough.

[0054] When the sweeper enters the base station's storage space, the sweeper's wastewater tank 300 is positioned corresponding to the wastewater trough. The seal 2 is located within the rotational stroke range of the end of the swing arm assembly 1. By swinging the arm assembly 1, the seal 2 is lifted, opening the outlet of the wastewater tank 300. The wastewater in the wastewater tank 300 is discharged into the wastewater trough, realizing the automatic discharge of sewage from the sweeper, which is very convenient.

[0055] Furthermore, one end of the swing arm assembly 1 is connected to a drive component that drives the swing arm assembly 1 to rotate so that the other end lifts the seal 2. The drive component drives the swing arm assembly 1 to rotate actively, thereby completing the lifting action of the swing arm assembly 1 on the seal 2.

[0056] Specifically, such as Figure 4 , Figure 5 and Figure 6 As shown, the swing arm assembly 1 includes at least a first swing arm 11, a second swing arm 12, and a rotating shaft 15. One end of the second swing arm 12 is connected to one end of the first swing arm 11, and the second swing arm 12 is set at an angle to the first swing arm 11. The rotating shaft 15 is located at the connection between the first swing arm 11, the second swing arm 12, or the first swing arm 11 and the second swing arm 12. The first swing arm 11 and the second swing arm 12 are set at an angle to change the orientation of the first swing arm 11 or the second swing arm 12 in lifting the seal 2. Lifting and resetting are achieved by rotating along the rotating shaft 15.

[0057] See also Figure 6 In this embodiment, a third swing arm 13 is also provided at the end of the first swing arm 11 away from the second swing arm 12. The third swing arm 13 and the first swing arm 11 are arranged at an angle. The third swing arm 13 extends in the opposite direction to the second swing arm 12, and the extended end of the third swing arm 13 movably lifts the seal 2. The third swing arm 13 extends obliquely upward in the vertical direction, which facilitates the application of an oblique upward thrust to the seal 2 and makes it easier to lift the seal 2.

[0058] In addition, such as Figure 6 As shown, a fourth swing arm 14 is provided at the end of the second swing arm 12 away from the first swing arm 11. The fourth swing arm 14 is set at an angle to the second swing arm 12, and the fourth swing arm 14 extends in the opposite direction to the first swing arm 11.

[0059] Preferably, the swing arm assembly 1 is arranged in a "W" shape. The specific lengths of the first swing arm 11, the second swing arm 12, the third swing arm 13 and the fourth swing arm 14 can be set according to the size of the accommodating space of the base plate 200. This embodiment does not make specific limitations on this.

[0060] Optionally, the swing arm assembly 1 may have only a first swing arm 11 and a second swing arm 12, that is, the swing arm assembly 1 is arranged in a "V" shape. Alternatively, the swing arm assembly 1 may have a first swing arm 11, a second swing arm 12 and a third swing arm 13, that is, the swing arm assembly 1 is arranged in an "N" shape, etc.

[0061] The first swing arm 11, the second swing arm 12, the third swing arm 13 and the fourth swing arm 14 are integrally formed. The integrally formed structure has good sturdiness and is not easily deformed during use. The third swing arm 13 is formed by bending one end of the first swing arm 11, and the fourth swing arm 14 is formed by bending one end of the second swing arm 12.

[0062] To improve the strength of the swing arm assembly 1, such as Figure 5 and Figure 6 As shown, a reinforcing rib 111 is provided on the longer swing arm section to reduce the possibility of swing arm deformation and extend service life. Exemplarily, the first swing arm 11 of this embodiment is provided with a reinforcing rib 111, which surrounds the outer periphery of the first swing arm 11 and is located at the middle section of the first swing arm 11.

[0063] Specifically, such as Figure 6 As shown, the driving component includes a first driving motor 3, which is mounted on the base plate 200. A cam 31 is provided at the output end of the first driving motor 3. The outer periphery of the cam 31 abuts against one end of the swing arm assembly 1 to drive the swing arm assembly 1 to rotate. More specifically, the outer periphery of the cam 31 abuts against the fourth swing arm 14. The first driving motor 3 drives the cam 31 to rotate. When the cam 31 rotates to its protruding portion, it pushes the fourth swing arm 14 to swing downwards, causing the swing arm assembly 1 to rotate. Simultaneously, the third swing arm 13 rises upwards to lift the seal 2. The fourth swing arm 14 facilitates the installation of the driving component, makes the structural fit more tightly, and makes reasonable use of the internal space of the base station.

[0064] Furthermore, such as Figure 6 As shown, a limiting plate 141 is also provided on the end face of the fourth swing arm 14 that abuts against the cam 31. There are two limiting plates 141, which are spaced apart, and the cam 31 is located between the two limiting plates 141. This ensures that the cam 31 will not be misaligned, resulting in better stability.

[0065] In this embodiment, the sealing element 2 is T-shaped, and a second elastic element 21 is sleeved on its outer periphery. The second elastic element 21 is located inside the water outlet and abuts against the stepped surface of the sealing element 2 and the inner wall of the water outlet. When the swing arm assembly 1 pushes the sealing element 2 to rise, the second elastic element 21 compresses and stores force. When the sweeper moves out of the accommodating space of the base station, the sealing element 2 loses the lifting force of the swing arm assembly 1, and the elastic force of the second elastic element 21 pushes the sealing element 2 back to its original position, thereby sealing the water outlet of the sewage tank 300. Preferably, the second elastic element 21 is a spring.

[0066] In one embodiment, the driving component can be replaced with other structures. For example, a first elastic element (not shown in the figure) is sleeved at the pivot 15 of the swing arm assembly 1. One end of the first elastic element is connected to the swing arm assembly 1, and the other end is connected to the base plate 200. When the sweeper enters the base station, it presses against the swing arm assembly 1 to rotate, causing the first elastic element to twist and store force. When the sweeper enters the base station and the swing arm assembly 1 is aligned with the seal 2, the elastic force of the first elastic element pushes the swing arm assembly 1 to rotate in the opposite direction, thereby lifting the seal 2. The structure is simple and easy to manufacture. Preferably, the first elastic element is a torsion spring.

[0067] In another embodiment, the driving component can be replaced with other structures. For example, the driving component includes a second driving mechanism, which is disposed on the base plate 200 and whose output end is connected to the rotating shaft 15 to drive the swing arm assembly 1 to rotate. The second driving mechanism is a second driving motor (not shown in the figure). The second driving motor drives the rotating shaft 15 to rotate forward or backward, so that the swing arm assembly 1 connected to the rotating shaft 15 rotates synchronously. The second driving motor drives the swing arm assembly 1 to rotate forward, driving the third swing arm 13 to rotate upward to lift the seal 2. The second driving motor drives the swing arm assembly 1 to rotate in reverse, driving the third swing arm 13 to rotate downward to reset the swing arm assembly 1. That is, the output end of the driving motor is directly connected to the rotating shaft 15, driving the rotating shaft 15 to rotate.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
