[0036] Embodiment 1

[0037] This embodiment provides a cleaning device, such as Figures 1 to 4 As shown, the cleaning device includes a body 100, at least two cleaning members 200, a driving member 300, and a transmission assembly 400. Among them, the two cleaning members 200 are arranged at intervals one in front of the other along a first direction, and the extending direction of the cleaning member 200 intersects the first direction. The first direction is the traveling direction of the body 100. The driving member 300 is installed on the body 100, and the driving member 300 is respectively drivingly connected to the two cleaning members 200 through the transmission assembly 400. Among them, one end of any cleaning member 200 is connected to the transmission assembly 400, and the other end is exposed outside the lateral edge of the body 100.

[0038] Specifically, the ends of the two cleaning members 200 located on different sides are exposed outside the lateral edge of the body 100.

[0039] Specifically, two cleaning members 200 are installed on the body 100 of the cleaning device and are arranged one in front of the other along the first direction. The driving member 300 drives the two cleaning members 200 to rotate through the transmission assembly 400 to clean the surface to be cleaned. The extending direction of the two cleaning members 200 is perpendicular to the first direction. One end of any cleaning member 200 is connected to the transmission assembly 400, and the other end is exposed at the lateral edge of the body 100.

[0040] One end of any cleaning member 200 is connected to the transmission assembly 400, and the other end is exposed at the lateral edge of the body 100, so that the two cleaning members 200 cooperate to clean all areas between the two opposite sides of the body 100, avoiding the existence of cleaning blind spots, cleaning more comprehensively, effectively improving the cleaning efficiency, and increasing the user experience.

[0041] In this embodiment, the cleaning member 200 is a rotary brush. During the movement of the cleaning device, the two rotary brushes work together to drive the objects to be cleaned on the surface to be cleaned to the dust collection port 103 on the body 100 through rotation, and the objects to be cleaned are collected through the dust collection port 103.

[0042] Such as Figures 1 to 4 As shown, the diameter of one of the cleaning members 200 among the two cleaning members 200 is larger than that of the other cleaning member 200.

[0043] Specifically, by using the cleaning members 200 with different diameters in cooperation, the area between a set of opposite sides of the body 100 is comprehensively cleaned, effectively improving the cleaning efficiency. Among them, the diameter of the cleaning member 200 at the front end in the forward direction is larger than that of the cleaning member 200 at the rear end. The front-end cleaning member 200 provides traction while cleaning the objects to be cleaned during rotation, so that the body 100 moves forward.

[0044] Further, the specific dimensions of the cleaning member 200, such as length and diameter, can be adaptively designed according to the dimensions of the body 100, specifically to fully clean the area between a set of opposite sides of the body 100.

[0045] As Figure 2 shown, an installation area 104 is formed between the two cleaning members 200. The driving member 300 and the transmission assembly 400 are both accommodated in the installation area 104, and the dust collection port 103 is arranged inside the installation area 104.

[0046] Specifically, the two driving members 300 are connected to the same driving member 300 through the transmission assembly 400. The input end of the transmission assembly 400 is drivingly connected to the driving member 300, and the output ends of the transmission assembly 400 are respectively drivingly connected to the two cleaning members 200, so that the rotation directions of the two cleaning members 200 are opposite, so as to collect the object to be cleaned at the dust collection port 103 of the installation area 104.

[0047] Further, the driving member 300 can be a structural member that provides power such as a driving motor or a driving cylinder.

[0048] As Figure 2 shown, the body 100 has a first side wall 101 and a second side wall 102 that are oppositely arranged. The two cleaning members 200 are respectively a first cleaning member and a second cleaning member. The first end of the first cleaning member extends to the edge of the first side wall 101, and there is a first installation gap between the second end of the first cleaning member and the second side wall 102 of the body 100. At least a part of the transmission assembly 400 extends into the first installation gap and is drivingly connected to the first cleaning member; the first end of the second cleaning member extends to the edge of the second side wall 102, and there is a second installation gap between the second end of the second cleaning member and the first side wall 101 of the body 100. At least another part of the transmission assembly 400 extends into the second installation gap and is drivingly connected to the second cleaning member.

[0049] Specifically, at least a part of the transmission member extends into the first gap and is drivingly connected to the first cleaning member, and at least another part extends into the second gap and is drivingly connected to the second cleaning member, so as to enable the first cleaning member to clean the corresponding surface to be cleaned at the second gap, and the second cleaning member to clean the corresponding surface to be cleaned at the first gap. Through the cooperation of the first cleaning member and the second cleaning member for cleaning, the first cleaning member cleans the surface to be cleaned at the cleaning blind area of the second cleaning member, and the second cleaning member cleans the surface to be cleaned at the first cleaning member, so as to achieve a full cleaning of the area between the first side wall 101 and the second side wall 102 and improve the cleaning efficiency.

[0050] It should be noted that one of the first cleaning member and the second cleaning member is a large-diameter cleaning member 200, and the other is a small-diameter cleaning member 200, which can also be adjusted according to needs. Both the first cleaning member and the second cleaning member are detachably connected to the body 100.

[0051] As Figure 4 shown, the transmission assembly 400 includes a first transmission member 401, a second transmission member 402, a transmission shaft 403, and a third transmission member 404. The driving member 300 is drivingly connected to the input end of the first transmission member 401. The output end of the first transmission member 401 extends into the interior of the first installation gap and is drivingly connected to the first cleaning member. The driving member 300 is drivingly connected to the second transmission member 402. The second transmission member 402 is drivingly connected to the transmission shaft 403. The transmission shaft 403 is drivingly connected to the input end of the third transmission member 404. The output end of the third transmission member 404 extends into the interior of the second installation gap and is drivingly connected to the second cleaning member.

[0052] In this embodiment, three implementation manners are provided according to the different structures of the first transmission member 401, the second transmission member 402, and the third transmission member 404, which are specifically as follows.

[0053] As Figure 4 shown in the specific implementation manner, the first transmission member 401 and the second transmission member 402 are both conveyor belts, and the third transmission member 404 is two meshing gears.

[0054] Specifically, the output shaft of the driving member 300 is drivingly connected to one of the first cleaning member and the second cleaning member through a conveyor belt. The driving member 300 is drivingly connected to the transmission shaft 403 through a conveyor belt. The transmission shaft 403 is drivingly connected to one of the two gears. The other of the two gears is drivingly connected to the other of the first cleaning member and the second cleaning member.

[0055] Furthermore, the cleaning member 200 drivingly connected to the driving member 300 through a conveyor belt has the same rotation direction as the output shaft of the driving member 300. The transmission shaft 403 has the same rotation direction as the output shaft of the driving member 300. The other cleaning member 200 connected to the transmission shaft 403 through two meshing gears has a rotation direction opposite to that of the output shaft of the driving member 300.

[0056] In a specific implementation manner not shown, the first transmission member 401 is two meshing gears, and the second transmission member 402 and the third transmission member 404 are both conveyor belts.

[0057] Specifically, the output shaft of the driving member 300 is drivingly connected to one of the first cleaning member and the second cleaning member through two meshing gears. The driving member 300 is drivingly connected to the transmission shaft 403 through a conveyor belt, and the transmission shaft 403 is drivingly connected to the other of the first cleaning member and the second cleaning member through a conveyor belt.

[0058] Further, the cleaning member 200 drivingly connected to the driving member 300 through two meshing gears rotates in a direction opposite to that of the output shaft of the driving member 300. The transmission shaft 403 rotates in the same direction as the output shaft of the driving member 300, and the cleaning member 200 drivingly connected to the transmission shaft 403 through a conveyor belt rotates in the same direction as the output shaft of the driving member 300.

[0059] In a specific embodiment not shown, the first transmission member 401 is two meshing gears, and both the second transmission member 402 and the third transmission member 404 are two meshing gears.

[0060] Specifically, the driving member 300 is drivingly connected to one of the first cleaning member and the second cleaning member through two meshing gears, so that the cleaning member 200 rotates in a direction opposite to that of the driving shaft. The driving member 300 is drivingly connected to the transmission shaft 403 through two meshing gears, so that the transmission shaft 403 rotates in a direction opposite to that of the driving shaft. The transmission shaft 403 is drivingly connected to the other cleaning member 200 through two meshing gears, so that the cleaning member 200 rotates in a direction opposite to that of the driving shaft.

[0061] As Figure 2 shown, a dust collection port 103 is provided on the body 100. The dust collection port 103 is provided between the first cleaning member and the second cleaning member. The cleaning device further includes a pump body 500. The pump body 500 is installed on the body 100, and the pump body 500 and the driving member 300 are respectively arranged on both sides of the dust collection port 103.

[0062] Among them, the driving member 300 provides the power for the rotation of the cleaning member 200, and the pump body 500 is used to provide liquid.

[0063] Specifically, the cleaning device further includes a steam generating device 600. The steam generating device 600 is installed on the body 100 and connected to the pump body 500. The output port of the steam generating device 600 faces at least one of the first cleaning member, the second cleaning member, and the cleaning surface. The steam generating device 600 has a heater, and the start and stop of the heater are controlled to adjust the steam generating device 600 to spray steam or spray liquid.

[0064] Further, the steam generating device 600 has one or more output ports. When the steam generating device 600 has multiple output ports, the multiple output ports are arranged at intervals along the extending direction of the cleaning member 200.

[0065] Further, the steam generating device 600 has a liquid inlet and a heating chamber. The heater is disposed inside the heating chamber. When the heater operates, the liquid entering the heating chamber through the liquid inlet is heated and evaporated, and the steam generated by evaporation is discharged from the heating chamber through the outlet.

[0066] Of course, the heater is not limited to being disposed inside the heating chamber, and may also be disposed in the external area of the heating chamber to heat the heating chamber, and the liquid entering the heating chamber through the liquid inlet is evaporated to generate steam.

[0067] It should be noted that when the heater is not operating, the steam generating device 600 functions as a liquid distributor. The pump body 500 supplies liquid into the steam generating device 600, and the liquid is discharged from the steam generating device 600 through the outlet.

[0068] As Figure 1 and Figure 5 shown, the cleaning device further includes a first connecting arm 700 and a second connecting arm 800. One end of the first connecting arm 700 is rotatably connected to the body 100, and the second connecting arm 800 is rotatably connected to the other end of the first connecting arm 700. The rotation direction of the first connecting arm 700 is perpendicular to the rotation direction of the second connecting arm 800. Wherein, the first connecting arm 700 is rotatably connected to the body 100 and the first connecting arm 700 is rotatably connected to the second connecting arm 800 through a rotating shaft 900.

[0069] Specifically, the rotation direction of the first connecting arm 700 intersects with the rotation direction of the second connecting arm 800, preferably perpendicular, so as to achieve the effect that the first connecting arm 700 and the second connecting arm 800 can rotate relative to the body 100 in different directions. During use, the second connecting arm 800 is connected to the handle, and by adjusting the handle, the relative rotation between the body 100, the first connecting arm 700, and the second connecting arm 800 can be controlled to achieve cleaning of different positions.

[0070] Further, by rotating the angle between the first connecting arm 700 and the body 100, it is possible to clean a small space area through the handle.

[0071] In this embodiment, a limiting groove 1030 is provided on the rotating shaft 900. The cleaning device further includes a locking member. The locking member is installed on the body 100 and the first connecting arm 700. The rotating shaft 900 has a locked state and an unlocked state. When the rotating shaft 900 is in the locked state, at least a part of the locking member extends into the limiting groove 1030. When the rotating shaft 900 is in the unlocked state, the locking member disengages from the limiting groove 1030.

[0072] Specifically, at least a part of the locking member extends into the inner part of the limiting groove 1030 to achieve the locking function, so that the handle and the body 100 maintain a preset angle to clean the surface to be cleaned.

[0073] Furthermore, one or more limiting grooves 1030 are provided. When multiple limiting grooves 1030 are provided, the multiple limiting grooves 1030 are arranged at intervals along the circumferential direction of the rotating shaft 900, and a preset angle is provided between the multiple limiting grooves 1030, so that the handle can be locked at multiple different positions when the rotating shaft 900 is in the locked state, ensuring that the handle cannot move freely.

[0074] It should be noted that the preset angle can be adaptively set according to actual requirements.

[0075] As Figure 5 shown, the locking member includes a limiting protrusion 1010 and an elastic member 1020. Installation grooves are provided on the body 100 and the first connecting arm 700. One end of the elastic member 1020 abuts against the groove wall of the installation groove, and the other end of the elastic member 1020 is connected to the limiting protrusion 1010. When the rotating shaft 900 is in the locked state, at least a part of the limiting protrusion 1010 extends into the inner part of the limiting groove 1030. When the rotating shaft 900 is in the unlocked state, the limiting protrusion 1010 disengages from the limiting groove 1030.

[0076] Specifically, the elastic member 1020 provides a restoring force in the direction away from the bottom of the installation groove for the limiting groove 1030. The structure of the elastic member 1020 cooperating with the limiting protrusion 1010 is used to lock or unlock the rotating shaft 900, which is convenient for operation.

[0077] Embodiment 2

[0078] The difference between this embodiment and Embodiment 1 is that in this embodiment, two driving members 300 are provided, and the two driving members 300 are respectively drivingly connected to the two cleaning members 200.

[0079] Specifically, the two driving members 300 are installed on the body 100, the two driving members 300 are respectively drivingly connected to the two cleaning members 200, and the rotation directions of the output shafts of the two driving members 300 are opposite, so that under the drive of the two driving members 300, the two cleaning members 200 rotate in opposite directions.

[0080] Embodiment 3

[0081] The difference between this embodiment and Embodiment 1 is that in this embodiment, the body 100 is not only provided with a steam generating device 600 but also provided with a liquid distributor.

[0082] Specifically, the cleaning device further includes a liquid distributor disposed on the body 100. The liquid distributor is connected to the pump body 500 so that the pump body 500 supplies liquid to the liquid distributor, and the liquid outlet of the liquid distributor is arranged to face at least one of the two cleaning members 200.

[0083] Furthermore, the liquid distributor has one or more outlets. When the steam generating device 600 has multiple outlets, the multiple outlets are arranged at intervals along the extending direction of the cleaning member 200.

[0084] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0085] 1. One end of any one of the two cleaning members 200 is connected to the transmission assembly, and the other end extends out of the lateral edge of the body 100, so that the two cleaning members 200 cooperate to clean all areas between the two opposite sides of the body 100, avoiding the existence of cleaning blind spots, cleaning more comprehensively, effectively improving the cleaning efficiency, and increasing the user experience.

[0086] 2. By providing the first connecting arm 700 and the second connecting arm 800 that are rotatably connected, the angle adjustment between the body 100, the first connecting arm 700, and the second connecting arm 800 is realized, improving the practicability of the cleaning device.

[0087] 3. By using one driving member 300 to drive the two cleaning members 200 to act, the use efficiency is improved.

[0088] 4. A steam generating device 600 is arranged on the body 100 to spray liquid or steam onto the cleaning member 200 or the surface to be cleaned, improving the cleaning efficiency of the cleaning member 200.

[0089] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art can make other different forms of changes or modifications without creative efforts, and all should belong to the protection scope of the present invention.
