[0057] See also Figure 1 and Figure 2As shown, the embodiment of the present application provides a cleaning device for cleaning the floor and effectively reducing residual water stains on the floor. For ease of understanding, the cleaning device provided in the embodiment of the present application can be illustrated by taking a floor scrubber 100 as an example of an application scenario.

[0058] Specifically, the floor scrubber 100 includes a housing 110, a first cleaning assembly 120, and a drying assembly 130. The first cleaning assembly 120 and the drying assembly 130 are both mounted on the housing 110 and can move with the housing 110 as a whole. The first cleaning assembly 120 can preliminarily scrape off water stains on the ground, but will still leave a shallow layer of water film on the ground, which cannot be dried quickly. The drying assembly 130 can work synchronously with the first cleaning assembly 120, so as to dry the residual water film on the ground after the cleaning assembly preliminarily cleans the water stains on the ground, thereby improving the user experience.

[0059] In some embodiments, the first cleaning assembly 120 includes a first scraper bar 121, and the first scraper bar 121 can be controlled to contact or stay away from the ground. In this way, the first scraper bar 121 can be adjusted according to the operation requirements during the operation of the floor scrubber 100. When the floor needs to be mopped, the first scraper bar 121 is extended to contact the ground, and the floor scrubber 100 is controlled to move as a whole, and the first scraper bar 121 in contact with the ground scrapes the water stains on the ground.

[0060] 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 scrubber 100 provided with the first scraper bar 121 is referred to as the "front", the end of the scrubber 100 facing away from the first scraper bar 121 is referred to as the "rear", the upper side in the direction of gravity is referred to as the "upper" and "top", and the lower side in the direction of gravity is referred to as the "lower" and "bottom".

[0061] Furthermore, the first cleaning assembly 120 further includes a driving mechanism, which is mounted on the housing 110 and has an output end connected to the first scraper bar 121 to drive the first scraper bar 121 to contact or separate from the ground.

[0062] Exemplarily, the driving mechanism may be hydraulically driven, pneumatically driven, connecting rod driven, motor driven, or the like, so as to be able to control the operating state of the first scraper bar 121 under the action of electric control, thereby realizing the automated operation of the floor scrubber 100 .

[0063] In some embodiments, the driving mechanism includes a driving air pump 122, an air intake pipe 123, an air bag 124, an exhaust pipe 125, and an exhaust valve 126. The driving air pump 122 is connected to the air bag 124 through the air intake pipe 123, the exhaust valve 126 is connected to the air bag 124 through the exhaust pipe 125, and the side of the air bag 124 close to the ground is connected to the first scraper strip 121.

[0064] Specifically, the driving mechanism adopts a pneumatic driving method. The driving air pump 122 is installed in the housing 110 and connected to one end of the air inlet pipe 123 to deliver airflow to the air inlet pipe 123. The end of the air inlet pipe 123 away from the driving air pump 122 is connected to the airbag 124 to deliver the airflow of the driving air pump 122 to the airbag 124. The airbag 124 expands after receiving the airflow, thereby squeezing the first scraper 121 installed at the bottom of the airbag 124 toward the ground, so that the first scraper 121 contacts the ground. One end of the exhaust pipe 125 is connected to the airbag 124, and the other end is connected to the exhaust valve 126, and the exhaust valve 126 remains closed when the power is on, and remains open when the power is off. In this way, when the first scraper 121 is not needed to operate, the air pump 122 is powered off to stop supplying air, the exhaust valve 126 is powered off and opened, and the internal gas of the inflated airbag 124 is discharged through the exhaust pipe 125 and the exhaust valve 126. The airbag 124 contracts and the first scraper 121 is reset, thereby separating the first scraper 121 from the ground.

[0065] Continue reading Figure 3 , Figure 4 and Figure 5 As shown, further, the first cleaning component 120 also includes a limiting mechanism, which includes a limiting groove 128, a reset member 127 and an elastic member 129. The reset member 127 slides through the limiting groove 128 and its two ends are respectively connected to the airbag 124 and the first scraper strip 121. One end of the elastic member 129 is fixed to the limiting groove 128, and the other end is connected to the reset member 127.

[0066] Specifically, the limiting groove 128 is in the form of a long strip to accommodate the installation of the first scraper 121. The notch of the limiting groove 128 faces upward so that the elastic member 129 can be installed in the wire groove. A card slot is provided at the bottom end of the reset member 127 to install the first scraper 121 in the card slot of the reset member 127, so as to facilitate the disassembly and assembly of the first scraper 121. Preferably, in order to ensure the stable installation of the first scraper 121, a plurality of reset members 127 should be provided, such as two ends, three, four, etc., to clamp multiple parts of the first scraper 121 to ensure the stability of the first scraper 121 during operation.

[0067] The elastic member 129 is a compression spring, and the main body of the reset member 127 is a cylindrical structure. The elastic member 129 is sleeved on the cylindrical structure of the reset member 127, and one end of the elastic member 129 is fixed to the bottom surface of the limiting groove 128. The end of the reset member 127 connected to the airbag 124 is provided with a limiting end larger than the inner diameter of the spring, and the end of the elastic member 129 away from the limiting groove 128 contacts the limiting end of the reset member 127. In this way, during the downward adjustment process of the first scraper 121, the driving air pump 122 is started, the airbag 124 is inflated, and the reset member 127 drives the first scraper 121 to move downward to contact the bottom surface. In this process, the limiting end of the reset member 127 applies pressure to the elastic member 129, so that the elastic member 129 is compressed in the limiting groove 128. During the upward adjustment of the first scraper strip 121, the driving air pump 122 is closed, the airbag 124 is deflated through the exhaust pipe 125 and the exhaust valve 126, and the elastic member 129 is in a pressure-free state and resets under the drive of elastic potential energy, thereby applying an increasing pressure to the limit end of the reset member 127, driving the reset member 127 and the first scraper strip 121 to rise back to the initial position.

[0068] Continue reading Figure 6 and Figure 7 As shown, the drying component 130 includes a drying air pump 132 and an air cavity 131. The drying air pump 132 is connected to the air cavity 131 through a pipeline. The air cavity 131 is located on one side of the first scraper strip 121 and has a drying port 1311 facing the ground.

[0069] Specifically, when the air-drying air pump 132 is powered on, it can deliver air-drying air to the air cavity 131 through the pipeline, and blow dry air to the bottom surface through the air-drying port 1311. The air cavity 131 is installed at the front end of the first scraper bar 121, so that when the floor scrubber 100 runs backward, the first scraper bar 121 is lowered to contact the bottom surface to preliminarily remove water stains on the bottom surface. However, there will still be a small amount of water film on the ground. Therefore, through the synchronous start-up of the air-drying air pump 132, the water film remaining on the bottom surface is dried by the dry air blown out of the air-drying port 1311 located at the front end of the first scraper bar 121, so as to achieve rapid drying of the bottom surface and improve user experience.

[0070] In some embodiments, the cleaning device also includes a second cleaning component 140, which includes a roller brush 141. The roller brush 141 is rotatably mounted at one end of the shell 110 and at least part of its surface is exposed to a side of the shell 110 close to the ground. The first scraper strip 121 and the air cavity 131 are mounted on the same side of the roller brush 141.

[0071] Specifically, the roller brush 141 is installed on the rear side of the second scraper bar 142 and can rotate with the scrubber 100 during its movement. The roller brush 141 contacts the ground to roll up the garbage on the ground during its movement. It is understandable that the scrubber 100 is provided with an air duct and a fan inside so that the rolled garbage can be sucked into a collection container through the air duct by the fan to achieve garbage cleaning on the ground. Therefore, the scrubber 100 can clean the garbage on the ground through the roller brush 141 during its forward movement, and in order to prevent the garbage from being blocked by the first scraper bar 121 in front, when the scrubber 100 moves forward, the first scraper bar 121 is kept separated from the ground by the action of the elastic member 129 through the driving stop operation. During the movement of the scrubber 100, the garbage on the ground contacts the roller brush 141 through the gap between the first scraper bar 121 and the ground and is rolled up and collected by the roller brush 141. When the floor scrubber 100 moves backward, a large amount of water stains are generated during the friction between the roller brush 141 and the ground. At this time, the driving air pump 122 can be started to lower the first scraper bar 121 to contact the ground, so that the water stains on the ground can be initially scraped off during the operation of the roller brush 141. In addition, the air drying air pump 132 is started simultaneously to air dry the ground treated by the first scraper bar 121 again to keep the ground dry.

[0072] Furthermore, the second cleaning assembly 140 further includes a second scraper bar 142 , which is installed on a side of the housing 110 close to the ground and located on a side of the roller brush 141 facing away from the first scraper bar 121 .

[0073] Specifically, when the floor scrubber 100 moves forward, the roller brush 141 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 second scraper bar 142 at the rear end of the roller brush 141 cleans the water stains, leaving only a shallow layer of water film on the ground, which is convenient for subsequent air drying.

[0074] In some embodiments, the floor scrubber 100 further includes a traveling assembly 150 and a control assembly. The traveling assembly 150 is mounted on the housing 110 and can drive the floor scrubber 100 to move as a whole. The control assembly is electrically connected to the first cleaning assembly 120, the drying assembly 130 and the traveling assembly 150, respectively.

[0075] It is understandable that the control component may include a processing chip and a number of operating buttons, and will determine the received signal and make control instructions through the internal running program. The walking component 150 includes a set of walking wheels and a drive motor. The control component is electrically connected to the drive motor to obtain the rotation direction of the drive motor, and then determine the movement direction of the floor scrubber 100, and adjust the operation mode of the first cleaning component 120 and the drying component 130 according to the movement direction of the floor scrubber 100.

[0076] Furthermore, the floor scrubber 100 further includes a detection component, which is electrically connected to the control component. A sewage pipe 111 is provided in the housing 110 , and the detection component is disposed in the sewage pipe 111 to detect the degree of dirtiness of the sewage pipe 111 .

[0077] Specifically, the sewage pipe 111 is used to connect the air duct inside the housing 110 and the sewage tank, so that the garbage collected by the roller brush 141 is transported to the sewage tank under the drive of the fan, so that the current dirtiness of the ground can be judged according to the dirtiness of the sewage pipe 111. When the ground is too dirty, the control component will limit the start of the driving air pump 122 to prevent the first scraper 121 from contacting the ground, causing the first scraper 121 to become dirty, reducing the frequency of later replacement and increasing the service life.

[0078] Exemplarily, the detection component includes an infrared transmitter and an infrared receiver that are relatively arranged, the sewage pipe 111 is made of a transparent material, and the infrared transmitter and the infrared receiver are respectively arranged on two opposite sides of the sewage pipe 111. In this way, during the operation of the floor scrubber 100, the sewage pipe 111 will flow through the sewage after cleaning, and the turbidity of the sewage can effectively reflect the current cleanliness of the ground. Therefore, when the ground is relatively clean, the turbidity of the sewage in the sewage pipe 111 is low, the infrared light emitted by the infrared transmitter can effectively penetrate the sewage pipe 111, and be received by the infrared receiver that is relatively arranged. After the control component obtains the receiving signal of the infrared receiver, it is determined that the current cleanliness of the ground is not dirty. When the ground is not clean or there are stubborn stains, the turbidity of the sewage in the sewage pipe 111 is high, the infrared light emitted by the infrared transmitter cannot effectively penetrate the sewage pipe 111, and the infrared receiver that is relatively arranged cannot receive the infrared light signal. After the control component obtains the non-receiving signal of the infrared receiver, it is determined that the current cleanliness of the ground is dirty. In this way, the control component will control the descent of the first scraper bar 121 to prevent the first scraper bar 121 from getting dirty, until the detection component detects that the sewage pipe 111 is not dirty, and the driving air pump 122 can operate normally to control the descent movement of the first scraper bar 121 to clean the residual water stains on the ground.

[0079] The embodiments of the present application also provide a cleaning method, which uses the floor scrubber 100 in any of the above embodiments.

[0080] Continue reading Figure 8 As shown, in some embodiments, the cleaning method includes:

[0081] S101, the control component determines that the dirt information of the sewage pipeline 111 is not dirty based on the signal of the detection component, and the driving air pump 122 and the air drying air pump 132 can operate normally.

[0083] Specifically, the garbage to be cleaned can be rolled up by the roller brush 141 through the gap between the first scraper bar 121 and the ground, and the second scraper bar 142 follows to clean the water stains remaining on the ground by the roller brush 141, thereby achieving normal cleaning of the garbage on the ground without causing the garbage to be blocked by the first scraper bar 121.

[0087] Specifically, after cleaning the garbage forward, the roller brush 141 can continue to rotate backward to mop the ground again, and the first scraper bar 121 located at the front end of the roller brush 141 can effectively clean the water stains left on the ground by the roller brush 141. At the same time, the air drying port 1311 located on the front side of the first scraper bar 121 blows out dry air, and the ground treated by the first scraper bar 121 is dried, thereby improving the user experience.

[0088] Continue reading Fig.10 As shown, in some other embodiments, the cleaning method further comprises:
