[0002] In the related art, in the cleaning device involving water cleaning, a scraping strip is usually arranged on one side of a rolling brush. During operation, the rolling brush often rubs against the ground and leaves a large amount of water stains.

[0076] Referring to Figure 1 As shown, the embodiment of the present application provides a cleaning device 100, which can be used for floor cleaning and effectively reduces the residual water stains on the floor. For ease of understanding, the cleaning device 100 provided by the embodiment of the present application can be exemplified by a scrubber.

[0077] Continuing to refer to Figure 2 As shown, specifically, the cleaning device 100 includes a machine body 110, a traveling assembly 120, a first cleaning assembly 130, and a second cleaning assembly 140. The traveling assembly 120 is installed at one end of the machine body 110 and can drive the machine body 110 to move as a whole. The second cleaning assembly 140 is installed at an end of the machine body 110 away from the traveling assembly 120. The first cleaning assembly 130 is installed between the second cleaning assembly 140 and the traveling assembly 120.

[0078] It should be noted that for ease of understanding, the orientation in the embodiment of the present application is explained. In the present application, the end of the cleaning device 100 provided with the traveling assembly 120 is "rear", the end of the cleaning device 100 away from the traveling assembly 120 is "front", the direction above the gravity is "upper" and "top", and the direction below the gravity is "lower" and "bottom".

[0079] In some embodiments, the cleaning device 100 further includes a control assembly, the traveling assembly 120 includes at least one set of traveling wheels 121 and a hub motor 122. Each set of traveling wheels 121 includes two traveling wheels 121 arranged opposite to each other on two sides of the machine body 110. The hub motor 122 is installed on one of the traveling wheels 121 and is electrically connected to the control assembly.

[0080] In the specific embodiment, there is only one set of traveling wheels 121, and the two traveling wheels 121 are installed on two opposite sides of the rear end of the machine body 110. The hub motor 122 is installed in one of the traveling wheels 121, thereby driving the traveling wheel 121 to rotate. The control assembly can receive the operation signal of the hub motor 122, determine the running direction of the whole machine, and make adjustment on the running mode.

[0081] Specifically, the wheel hub motor 122 refers to integrating the power device, transmission device and brake device together into the wheel hub, thereby simplifying the mechanical part of the machine body 110. It can be understood that the control assembly can include a processing chip and a plurality of operation buttons, and will determine the received signal and make control instructions through the internal running program.

[0082] Referring to Figure 3 In some embodiments, the walking assembly 120 includes a plurality of walking wheels 121 and an encoder 123, and the encoder 123 is installed on one of the walking wheels 121 and is electrically connected to the control assembly.

[0083] Specifically, the walking assembly 120 can adopt an alternating current asynchronous motor installed in the machine body 110, and the motor drives the walking wheel 121 to rotate. The encoder 123 installed on the walking wheel 121 obtains the rotation signal of the walking wheel 121 and sends it to the control assembly. The control assembly determines the received signal and makes control instructions through the internal running program.

[0084] Of course, the walking assembly 120 can also adopt other types of motors, which can meet the rotation of the walking wheel 121, and will not be enumerated here. The number of walking wheels 121 can also be two or more, and can be installed on the other side of the non-rear end of the machine body 110. The specific selection can meet the normal operation of the cleaning device 100.

[0085] Referring to Figure 4 and Figure 5 In some embodiments, the first cleaning assembly 130 includes a roller brush 131 installed on the front end of the machine body 110.

[0086] Specifically, during the operation of the cleaning device 100, the bottom side of the roller brush 131 contacts the ground, and during the walking process of the walking wheel 121 driving the whole machine, the ground garbage is rolled and cleaned.

[0087] Referring to Figure 6 It can be understood that the cleaning device 100 also includes a dirty channel 113, a fan and a sewage tank, so that during the operation, the fan can absorb the garbage rolled by the roller brush 131 and discharge it to the sewage tank through the dirty channel 113.

[0088] Further, the first cleaning assembly 130 also includes a first scraping strip 132 fixed to one side of the roller brush 131 close to the walking assembly 120.

[0089] Specifically, when the cleaning device 100 runs forward, the roller brush 131 located at the front end rolls the garbage and at the same time rubs the ground, thereby leaving water stains on the ground. In this way, the first scraping strip 132 located at the rear end of the roller brush 131 cleans the water stains, so that the ground only leaves a layer of shallow water film, which can be quickly air-dried.

[0090] With reference to the drawings Figure 7 Further, the first cleaning assembly 130 further comprises a scraper 133, which is mounted on the side of the roller brush 131 opposite to the squeegee mechanism 142 and abuts against the roller brush 131.

[0091] Specifically, the rear end of the scraper 133 is fixed inside the machine body 110, and the front end abuts against the rear side of the roller brush 131, so that when the roller brush 131 is running forward, the garbage adhered to the roller brush 131 is scraped off and sucked into the sewage tank by the air blower.

[0092] With reference to the drawings Figure 8 In some embodiments, the side of the dirty channel 113 is provided with a detection mechanism 114, and the control assembly is electrically connected with the detection mechanism 114. The detection mechanism 114 can obtain the dirty information of the dirty channel 113 and send it to the control assembly.

[0093] For example, the detection mechanism 114 comprises an infrared emitter and an infrared receiver arranged opposite to each other. The dirty channel 113 is made of transparent material, and the infrared emitter and the infrared receiver are arranged on the two opposite sides of the dirty channel 113. In this way, during the operation of the cleaning device 100, the dirty channel 113 will flow with the cleaned sewage, and the turbidity of the sewage can effectively reflect the current cleaning state of the ground. Therefore, when the ground is relatively clean, the turbidity of the sewage in the dirty channel 113 is low, the infrared light emitted by the infrared emitter can effectively penetrate the dirty channel 113 and be received by the oppositely arranged infrared receiver. After the control assembly obtains the receiving signal of the infrared receiver, it determines that the current ground cleaning degree is not dirty. When the ground is not clean, the turbidity of the sewage in the dirty channel 113 is high, the infrared light emitted by the infrared emitter cannot effectively penetrate the dirty channel 113, and the oppositely arranged infrared receiver cannot receive the infrared light signal. After the control assembly obtains the non-receiving signal of the infrared receiver, it determines that the current ground cleaning degree is dirty.

[0094] In some embodiments, the second cleaning assembly 140 is mounted on the side of the roller brush 131 opposite to the walking assembly 120 and comprises a driving mechanism 141 and a squeegee mechanism 142, and the driving mechanism 141 is in transmission connection with the squeegee mechanism 142. In this way, the driving mechanism 141 can drive the squeegee mechanism 142 to contact or separate from the ground to cooperate with the walking assembly 120 to realize various operation modes of the cleaning device 100.

[0095] Further, the machine body 110 comprises a first cover 111 and a second cover 112. The first cover 111 covers the side of the roller brush 131 opposite to the ground, and the second cover 112 is located on the side of the first cover 111 opposite to the roller brush 131. The squeegee mechanism 142 slides and extends between the first cover 111 and the second cover 112.

[0096] Specifically, the first cover 111 is arranged on the top side of the rolling brush 131 to protect the rolling brush 131. Meanwhile, the first cover 111 can play the effect of a fender. During the rotation of the rolling brush 131, water stains attached to the rolling brush 131 are blocked by the first cover 111 and cannot splash to the outside of the machine body 110. In addition, the first cover 111 provides a mounting carrier for the second cleaning assembly 140, effectively separating the second cleaning assembly 140 from the rolling brush 131. The first cover plate covers the second cleaning assembly 140, thereby providing protection for the second cleaning assembly 140.

[0097] Continuing to refer to Figure 9 Further, the driving mechanism 141 includes a driving motor 1411, a cam and a connecting rod set 1412. The driving motor 1411 is fixedly installed in the machine body 110 and connected with the cam. One end of the connecting rod set 1412 is connected with the cam, and the other end is connected with the wiper strip mechanism 142. The wiper strip mechanism 142 is in sliding fit with the first cover 111.

[0098] For example, the driving motor 1411 can be a brushless motor, the output of which is connected with the cam to drive the cam. The connecting rod set 1412 includes a first connecting rod 14121 and a second connecting rod 14122. The first connecting rod 14121 is rotatably connected with one side of the cam, and the other end is rotatably connected with the second connecting rod 14122. The second connecting rod 14122 is rotatably connected with the wiper strip mechanism 142 at the end away from the first connecting rod 14121. The wiper strip mechanism 142 is in sliding fit with the first cover 111 along the direction of gravity. In this way, under the drive of the driving motor 1411, the cam drives the first connecting rod 14121 and the second connecting rod 14122 to rotate and contract in turn. The wiper strip mechanism 142 cannot rotate under the restriction of the first cover 111, and can only move along the direction of gravity, so as to realize the extension and contraction of the wiper strip mechanism 142, and make the wiper strip mechanism 142 contact or separate from the ground.

[0099] It should be noted that the start of the driving motor 1411 can also be controlled by the control assembly, so as to limit the start of the driving motor 1411 when the control assembly determines that the ground is too dirty, and the second wiper strip 1422 is kept separated from the ground.

[0100] Continuing to refer to Figure 10 Further, the wiper strip mechanism 142 includes a bracket 1421, a second wiper strip 1422 and at least one guide rib 1423. The second wiper strip 1422 is fixed to the lower end of the bracket 1421 in the direction of gravity. Each guide rib 1423 is arranged in parallel with the direction of gravity and is fixed to the side of the bracket 1421 away from the second wiper strip 1422. The first cover 111 is provided with at least one sliding groove 1111 corresponding to each guide rib 1423 in parallel with the direction of gravity.

[0101] Exemplarily, the guide ribs 1423 and the sliding grooves 1111 are both provided with two to ensure the smooth movement of the scraping strip mechanism 142. During the operation of the driving motor 1411, the connecting rod set 1412 drives the bracket 1421 to move, and under the limitation of the guide ribs 1423 and the sliding grooves 1111, the bracket 1421 can only move along the extension direction of the sliding grooves 1111, thereby driving the second scraping strip 1422 fixed to the bottom of the bracket 1421 to stretch and retract up and down.

[0102] Referring back to Figure 11 Further, the first cover body 111 is further provided with a first limiting rib 115 and a second limiting rib 116 oppositely distributed, and the bracket 1421 is limited between the first limiting rib 115 and the second limiting rib 116.

[0103] Specifically, the first limiting rib 115 and the second limiting rib 116 both extend along the length direction of the bracket 1421 and oppositely distribute up and down. It can be understood that the projection of the first limiting rib 115 in the direction of gravity is a first projection surface, the projection of the second limiting rib 116 in the direction of gravity is a second projection surface, and the projection of the top surface of the bracket 1421 in the direction of gravity is a third projection surface, and the first projection surface, the second projection surface and the third projection surface have the same overlapping area. In this way, when the bracket 1421 rises to the set position, it will be blocked by the first limiting rib 115, and when it falls to the set position, it will be blocked by the second limiting rib 116, thereby achieving accurate positioning of the second scraping strip 1422.

[0104] Referring back to Figure 12 Further, the embodiment of the present application also provides a cleaning method using the cleaning device 100 in any of the above embodiments.

[0105] Referring back to Figure 13 In some embodiments, the cleaning method comprises:

[0107] S201, the cleaning device 100 enters a first working mode.

[0108] Specifically, the first working mode can be a garbage cleaning mode. The cleaning device 100 moves to the front end, the driving motor 1411 is paused, and the scraping strip mechanism 142 is controlled to separate from the ground. The garbage to be cleaned can be rolled up by the rolling brush 131 through the gap between the second scraping strip 1422 and the ground, and the first scraping strip 132 follows the cleaning rolling brush 131 to clean the water stains remaining on the ground, thereby achieving normal cleaning of the garbage on the ground without causing the garbage to be blocked by the second scraping strip 1422.

[0109] Further, the distance between the scraping strip mechanism 142 and the ground is d, and d≥10mm is satisfied.

[0110] For example, the distance d between the scraping strip mechanism 142 and the ground can be 10mm, 11mm, 12mm, 15mm, 17mm, 18mm, 19mm, etc., and can be reasonably selected according to the implementation requirements, and is not limited here. In this way, through the above design, the distance between the scraping strip mechanism 142 and the ground can be passed through the garbage to be cleaned, and then be rolled up by the roller brush 131.

[0111] Referring back to Figure 14 In some embodiments, the cleaning method further includes:

[0112] S101, the control assembly determines that the dirt information of the dirt channel 113 is not dirty according to the signal of the detection mechanism 114, and drives the motor 1411 to normally work.

[0113] S202, the cleaning device 100 enters a second working mode.

[0114] Specifically, the second working mode is a ground cleaning mode. The cleaning device 100 moves to the rear end, the motor 1411 is started, and the scraping strip mechanism 142 is controlled to be in contact with the ground. After cleaning the garbage in the forward direction, the roller brush 131 can continue to operate in the backward direction to clean the ground again, and the second scraping strip 1422 located at the front end of the roller brush 131 can effectively clean the water stains on the ground left by the roller brush 131, improving the user experience.

[0115] Referring back to Figure 15 In some embodiments, the cleaning method further includes:

[0116] S102, the control assembly determines that the dirt information of the dirt channel 113 is dirty according to the signal of the detection mechanism 114, and drives the motor 1411 to pause, and the scraping strip mechanism 142 is controlled to be separated from the ground.

[0117] S203, the cleaning device 100 enters a third working mode.

[0118] Specifically, the cleaning device 100 moves in any direction, and the second scraping strip 1422 will not be in contact with the ground, so as to avoid the ground being too dirty, the second scraping strip 1422 being dirty, reduce the maintenance time in the later period, and improve the service life of the device. Until the dirt degree of the ground reaches the set requirement, the cleaning device 100 can be controlled to enter the first working mode or the second working mode.

[0119] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0120] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
