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

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

[0078] It should be noted that, for ease of understanding, the directions in the embodiments of the present application are explained. In the present application, the end of the cleaning device 100 provided with the walking assembly 120 is referred to as the "rear", the end of the cleaning device 100 facing away from the walking assembly 120 is referred to as the "front", the upper side in the direction of gravity is referred to as the "upper" and the "top", and the lower side in the direction of gravity is referred to as the "lower" and the "bottom".

[0079] In some embodiments, the cleaning device 100 also includes a control component, the walking component 120 includes at least one group of walking wheels 121 and a hub motor 122, each group of walking wheels 121 includes two relatively arranged on both sides of the body 110, and the hub motor 122 is installed on one of the walking wheels 121 and is electrically connected to the control component.

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

[0081] Specifically, the hub motor 122 integrates the power device, transmission device and brake device into the hub, thereby simplifying the mechanical part of the body 110. It can be understood that the control component may include a processing chip and a plurality of operating buttons, and will judge the received signal and make control instructions through the internal running program.

[0082] Continue reading Figure 3 As shown, in other embodiments, the travel component 120 includes a group of travel wheels 121 and an encoder 123, and the encoder 123 is installed on one of the travel wheels 121 and is electrically connected to the control component.

[0083] Specifically, the walking component 120 can use an AC asynchronous motor installed in the body 110, and the motor drives the walking wheel 121 to operate. The encoder 123 installed on the walking wheel 121 obtains the operating signal of the walking wheel 121 and sends it to the control component. The control component judges the received signal through the internal running program and makes a control instruction.

[0084] Of course, the walking assembly 120 can also use other types of motors that can meet the operation of the walking wheels 121, and no examples are given here. The number of groups of walking wheels 121 can also be two or more, and they can be installed on the other side of the body 110 other than the rear end. The specific selection can be based on actual needs, as long as it can meet the normal operation of the cleaning device 100.

[0085] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, the first cleaning assembly 130 includes a roller brush 131 installed at the front end of the body 110 .

[0086] Specifically, during the operation of the cleaning device 100, the bottom side of the roller brush 131 contacts the ground, and the running wheels 121 drive the entire device to move, thereby rolling up and cleaning the garbage on the ground.

[0087] Continue reading Figure 6 As shown, it can be understood that the cleaning device 100 also includes a dirt channel 113, a fan and a sewage tank, so that during operation, the fan can absorb the garbage rolled up by the roller brush 131 and discharge it into the sewage tank through the dirt channel 113.

[0088] Furthermore, the first cleaning assembly 130 further includes a first scraper bar 132 , and the first scraper bar 132 is fixed to a side of the roller brush 131 close to the traveling assembly 120 .

[0089] Specifically, when the cleaning device 100 moves forward, the roller brush 131 at the front end rolls up the garbage and rubs against the ground at the same time, thereby leaving water stains on the ground. In this way, the first scraper bar 132 at the rear end of the roller brush 131 cleans the water stains, leaving only a shallow water film on the ground, which can be quickly dried.

[0090] Continue reading Figure 7 As shown, further, the first cleaning assembly 130 further includes a scraper 133 , which is mounted on a side of the roller brush 131 facing away from the scraper mechanism 142 and abuts against the roller brush 131 .

[0091] Specifically, the rear end of the scraper 133 is fixed inside the body 110, and the front end is in contact with the rear side of the roller brush 131, so that when the roller brush 131 moves forward, the garbage adhered to the roller brush 131 is scraped off and sucked into the sewage tank through the fan.

[0092] Continue reading Figure 8 As shown, in some embodiments, a detection mechanism 114 is provided on the side of the dirty channel 113, and the control component is electrically connected to the detection mechanism 114. The detection mechanism 114 can obtain dirt information of the dirty channel 113 and send it to the control component.

[0093] Exemplarily, the detection mechanism 114 includes an infrared transmitter and an infrared receiver that are arranged relatively, the dirty channel 113 is made of a transparent material, and the infrared transmitter and the infrared receiver are respectively arranged on two opposite sides of the dirty channel 113. In this way, during the operation of the cleaning device 100, the dirty channel 113 will circulate the cleaned sewage, and the turbidity of the sewage can effectively reflect the current clean 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 transmitter can effectively penetrate the dirty channel 113, and is received by the infrared receiver that is arranged relatively. After the control component obtains the receiving signal of the infrared receiver, it determines that the current cleanliness of the ground 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 transmitter cannot effectively penetrate the dirty channel 113, and the infrared receiver that is arranged relatively cannot receive the infrared light signal. After the control component obtains the non-receiving signal of the infrared receiver, it determines that the current cleanliness of the ground is dirty.

[0094] In some embodiments, the second cleaning assembly 140 is installed on the side of the roller brush 131 facing away from the walking assembly 120 and includes a driving mechanism 141 and a scraping mechanism 142, and the driving mechanism 141 is in transmission connection with the scraping mechanism 142. In this way, the driving mechanism 141 can drive the scraping mechanism 142 to contact or separate with the ground, so as to cooperate with the walking assembly 120 to realize multiple operation modes of the cleaning device 100.

[0095] Furthermore, the body 110 includes a first cover 111 and a second cover 112 , the first cover 111 covers the side of the roller brush 131 facing away from the ground, the second cover 112 is located on the side of the first cover 111 facing away from the roller brush 131 , and the scraper mechanism 142 slides and retracts between the first cover 111 and the second cover 112 .

[0096] Specifically, the first cover 111 is provided on the top side of the roller brush 131 to protect the roller brush 131. At the same time, the first cover 111 can play the role of a fender. During the rotation of the roller brush 131, the water stains attached to the roller brush 131 are blocked by the first cover 111 and cannot splash outside 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 roller brush 131. The first cover plate covers the second cleaning assembly 140, thereby providing protection for the second cleaning assembly 140.

[0097] Continue reading Fig. 9 As shown, further, the driving mechanism 141 includes a driving motor 1411, a cam and a connecting rod group 1412. The driving motor 1411 is fixedly installed in the body 110 and connected to the cam. One end of the connecting rod group 1412 is connected to the cam, and the other end is connected to the scraper mechanism 142. The scraper mechanism 142 is slidably matched with the first cover body 111.

[0098] Exemplarily, the drive motor 1411 may be a brushless motor, whose output device is connected to the cam, thereby driving the cam selection. The connecting rod group 1412 includes a first connecting rod 14121 and a second connecting rod 14122, wherein the first connecting rod 14121 is rotationally connected to one side of the cam, and the other end is rotationally connected to the second connecting rod 14122, and the end of the second connecting rod 14122 away from the first connecting rod 14121 is rotationally connected to the scraper mechanism 142, and the scraper mechanism 142 and the first cover body 111 slide in the direction of gravity. In this way, under the drive of the drive motor 1411, the cam drives the first connecting rod 14121 and the second connecting rod 14122 to rotate and shrink in turn, and the scraper mechanism 142 cannot follow the rotation under the restriction of the first cover body 111, so it can only move in the direction of gravity to achieve the extension and contraction of the scraper mechanism 142, so that the scraper mechanism 142 is in contact with or separated from the ground.

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

[0100] Continue reading Fig.10 As shown, further, the scraper mechanism 142 includes a bracket 1421, a second scraper 1422 and at least one guide rib 1423. The second scraper 1422 is fixed to the lower end of the bracket 1421 in the direction of gravity. Each guide rib 1423 is arranged parallel to the direction of gravity and fixed to the side of the bracket 1421 facing away from the second scraper 1422. The first cover 111 is correspondingly provided with at least one slide groove 1111 parallel to the direction of gravity, and each slide groove 1111 is distributed in a corresponding guide rib 1423 for sliding fit.

[0101] Exemplarily, two guide ribs 1423 and two slide slots 1111 are provided to ensure the stability of the scraper mechanism 142 during movement. During the operation of the drive motor 1411, the connecting rod assembly 1412 drives the bracket 1421 to move. Under the restriction of the guide ribs 1423 and the slide slot 1111, the bracket 1421 can only move along the extension direction of the slide slot 1111, thereby driving the second scraper 1422 fixed at the bottom of the bracket 1421 to extend and retract up and down.

[0102] Continue reading Fig.11 As shown, further, the first cover body 111 is further provided with a first limiting rib 115 and a second limiting rib 116 which are relatively 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 are relatively distributed up and down. It can be understood that the projection of the first limiting rib 115 in the direction of gravity is the first projection surface, the projection of the second limiting rib 116 in the direction of gravity is the second projection surface, and the projection of the top surface of the bracket 1421 in the direction of gravity is the third projection surface. 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 descends to the set position, it will be blocked by the second limiting rib 116, so as to achieve the precise positioning of the second scraper strip 1422.

[0104] Continue reading Fig.12 As shown, an embodiment of the present application further provides a cleaning method, which uses the cleaning device 100 in any of the above embodiments.

[0105] Continue reading Fig.13 As shown, in some embodiments, the cleaning method includes:

[0106] S101, the control component determines that the dirt information of the dirt channel 113 is not dirty according to the signal of the detection mechanism 114, and the driving motor 1411 can operate normally.

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

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

[0109] Furthermore, the distance between the scraper mechanism 142 and the ground is d, and satisfies: d≥10 mm.

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

[0111] Continue reading Fig.14 As shown, in some other embodiments, the cleaning method further comprises:

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

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

[0114] Specifically, the second operation mode is the floor cleaning mode. The cleaning device 100 moves to the rear end, the drive motor 1411 is started, and the scraper mechanism 142 is controlled to contact the floor. After cleaning the garbage forward, the roller brush 131 can continue to move backward to mop the floor again, and the second scraper bar 1422 located at the front end of the roller brush 131 can effectively clean the water stains left on the floor by the roller brush 131, thereby improving the user experience.

[0115] Continue reading Fig.15 As shown, in some other embodiments, the cleaning method further comprises:

[0116] S102, the control component determines that the dirt information of the dirt channel 113 is dirty according to the signal of the detection mechanism 114, the driving motor 1411 is paused, and the scraper mechanism 142 is controlled to separate from the ground.

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

[0118] Specifically, the second scraper bar 1422 will not contact the ground when the cleaning device 100 moves in any direction, so as to prevent the ground from being too dirty and soiling the second scraper bar 1422, thereby reducing the maintenance time and increasing the service life of the device. When the dirtiness of the ground reaches the set requirement, the cleaning device 100 can be controlled to enter the first operation mode or the second operation mode.

[0119] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations 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 protection scope of the patent application shall be subject to the attached claims.
