[0044] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0045] To more clearly describe the behavior of the floor brush of the cleaning equipment, as shown in Figure 1, the following directional definitions are made: The floor brush of the cleaning equipment can be categorized by the following three mutually perpendicular axes: the horizontal axis Y, the front-to-back axis X, and the central vertical axis Z. The direction along the arrow on the front-to-back axis X is labeled "backward," and the direction opposite to the arrow on the front-to-back axis X is labeled "forward." The direction along the arrow on the horizontal axis Y is the "right side" of the floor brush, and the direction opposite to the arrow on the horizontal axis Y is the "left side." The vertical axis Z extends upward along the bottom surface of the floor brush; the direction along the arrow on the vertical axis Z is the "top side" of the floor brush, and the direction opposite to the arrow on the vertical axis Z is the "bottom side."

[0046] As shown in Figure 1, a floor brush 100 for a cleaning device is provided according to some embodiments of this disclosure. The cleaning device may be, for example, a floor scrubber. The floor brush 100 is used to clean a surface (e.g., a floor) manually or automatically. The floor brush 100 includes a housing 110, a roller brush 120, a scraper 130, a drive assembly 140, a roller 150, a base 160, and a support wheel 170. The roller brush 120, scraper 130, drive assembly 140, roller 150, and support wheel 170 are mounted on the base 160. The housing 110 is fastened to the base 160. The support wheel 170 is located on the side of the base 160 closest to the roller brush 120. The roller 150 is located on the side of the support wheel 170 furthest from the roller brush 120. The base 160 has a suction port 161 through which dirt from the surface to be cleaned is sucked up. Under the action of an external power source, dirt entering through the suction port 161 is sucked into the wastewater tank through the suction pipe. A roller brush 120 is rotatably connected to the front end of the base 160; the roller brush 120 is driven to rotate by a roller brush drive mechanism to clean the surface to be cleaned. The roller brush 120 typically has a rigid shaft and soft brush parts or a brush cloth for dry or wet cleaning of the surface to be cleaned. A control assembly consists of a scraper 130, a drive assembly 140, and a controller (not shown). The control assembly is located on the side of the roller brush near the roller. The control assembly can adjust the angle of the scraper 130. The scraper 130 is movably connected to the base 160. The controller is connected to the scraper 130 through the drive assembly 140. The controller controls the rotation angle of the scraper 130 according to different working conditions. The scraper 130 is made of replaceable materials such as metal, alloy, or hard plastic. The scraper tip is made of soft rubber to facilitate contact with the surface to be cleaned and to adjust the pressure. By installing a drive assembly 140 and a controller on the scraper 130 of the floor brush in the cleaning equipment, the angle of the scraper 130 can be adjusted within a wide range. This allows for precise adjustment of the downward pressure of the scraper 130 under different working conditions, thereby improving the cleaning effect of the cleaning equipment. The control method for the downward pressure of the scraper 130 under different working conditions can be switched manually or automatically; there is no limitation in this regard. Furthermore, during the self-cleaning process, by controlling the movement of the cleaning equipment and the spraying of the cleaning fluid, the scraper 130 can be effectively cleaned and adjusted, thereby extending the service life of the scraper 130, maintaining the cleaning effect of the cleaning equipment, and improving the efficiency and user experience of the cleaning equipment.

[0047] In some embodiments, the controller controlling the rotation angle of the scraper 130 according to different working conditions may include adjusting the scraper to a preset position to match the status information of the floor brush of the cleaning equipment, based on the status information of the floor brush and the position information of the scraper. The scraper 130 is made of replaceable materials such as metal, alloy, or hard plastic. The end of the scraper is made of soft rubber to facilitate contact with the surface to be cleaned and to adjust the pressure on the surface to be cleaned. By setting the drive assembly 140 and the controller on the scraper 130 of the floor brush of the cleaning equipment, the angle of the scraper 130 can be adjusted within a large range to achieve precise adjustment of the downward pressure of the scraper 130 under different working conditions, thereby improving the cleaning effect of the cleaning equipment. Depending on the different control methods for the downward pressure of the scraper 130 under different working conditions, a manual switch can be set for switching, or an automatic control mode can be set; there is no limitation on this.

[0048] In some embodiments, in response to the cleaning device moving in a first direction, the first direction being forward, the roller brush 120 cleans the dirt on the surface to be cleaned by rotating; the controller controls the rotation angle of the scraper 130 so that it presses down and makes close contact with the surface to be cleaned. This close contact can be a completely seamless contact or a roughly seamless contact when the surface to be cleaned is uneven; when the surface to be cleaned is a soft surface (e.g., carpet), it can also be an embedded contact. A relatively enclosed space is formed between the roller brush 120, the surface to be cleaned, and the scraper 130; the suction port 161 located on the upper side of the scraper 130 can powerfully suck up the dirt in this relatively enclosed space through the gap between the scraper 130 and the roller brush 120; because the space is relatively enclosed, it is easier to create negative pressure, facilitating the removal of dirt from the relatively enclosed space, thereby improving the cleaning efficiency of the cleaning device.

[0049] In some embodiments, as shown in FIG1, the included angle A when the scraper 130 is in close contact with the surface to be cleaned is 80-100 degrees, for example, it can be 90 degrees, to improve the scraping effect.

[0050] In some embodiments, in response to the cleaning device moving in a second direction, which is backward, the controller controls the rotation angle of the scraper 130 to reduce or eliminate its downward pressure, ultimately creating a preset distance between the end of the scraper 130 and the surface to be cleaned; the preset distance is 2mm-5mm. Reducing the downward pressure between the end of the scraper 130 and the surface to be cleaned, for example, reducing it to 5N-25N, can reduce the resistance when the cleaning device moves backward and also reduce friction or damage to the scraper 130. At this time, there is still a certain distance between the scraper 130 and the roller brush 120, for example, a minimum distance of 2mm-5mm, so that there will be no scraping with the roller brush.

[0051] In some embodiments, the cleaning device cleans in a powerful mode in response to the cleaning device. The controller controls the rotation angle of the scraper 130 to ensure close contact with the surface to be cleaned. When performing a cleaning task, the cleaning device can select either a powerful mode or an economy mode depending on the degree of dirt on the surface. In powerful mode, the power source is strengthened, the rotation speed of the roller brush 120 is increased, and the suction power at the floor brush is also enhanced. At this time, the controller controls the rotation angle of the scraper 130 to press it down and ensure close contact with the surface to be cleaned, forming a relatively enclosed space between the roller brush 120, the surface to be cleaned, and the scraper 130. This allows the suction port 161 located on the upper side of the scraper 130 to powerfully suck up dirt from this relatively enclosed space through the gap between the scraper 130 and the roller brush 120. Because the space is relatively enclosed, it is easier to create negative pressure, facilitating the removal of dirt from the relatively enclosed space and thus improving the cleaning efficiency of the cleaning device.

[0052] In some embodiments, in response to the cleaning device cleaning in economy mode, the controller controls the rotation angle of the scraper 130 to maintain a preset distance from the surface to be cleaned. In economy mode, the power of the power source is reduced, and the rotation speed of the roller brush 120 is reduced to reduce energy consumption and noise. At this time, the controller controls the rotation angle of the scraper 130 to reduce or eliminate downward pressure, ultimately ensuring that the end of the scraper 130 maintains a preset distance from the surface to be cleaned; or, the end of the scraper 130 just touches the surface to be cleaned. This reduces friction or damage to the scraper 130, thereby increasing its service life.

[0053] In some embodiments, as shown in FIG2, the cleaning equipment returns to the base station for self-cleaning after completing its work. During self-cleaning, the roller brush 120 rotates at high speed, and cleaning fluid is sprayed onto the roller brush 120 to clean the dirt on its surface. In some cases, the roller brush 120 also needs to be dried. In this case, the controller controls the rotation angle of the scraper 130 so that it at least contacts the outer contour surface of the roller brush 120; or, the controller controls the rotation angle of the scraper 130 so that its contact position with the roller brush 120 is within the outer contour of the roller brush 120, i.e., the scraper 130 makes excessive contact with the outer surface of the roller brush 120. While the roller brush 120 rotates for self-cleaning, the scraper 130 can also be cleaned. During the self-cleaning process, by controlling the movement of the cleaning equipment and the spraying of the cleaning fluid, the scraper 130 can be effectively cleaned and adjusted, thereby extending the service life of the scraper 130, maintaining the cleaning effect of the cleaning equipment, and improving the efficiency and user experience of the cleaning equipment.

[0054] In some embodiments, as shown in FIG3, the drive assembly 140 includes a motor 141, a connector 142, an encoder 143, a gear set 144, etc. The drive assembly 140 is used to drive the scraper 130 to rotate within a preset angle. The motor 141 has a power output shaft 1411. The motor 141 provides forward and / or reverse driving force under the control of the controller. One end of the connector 142 is connected to the output shaft 1411 of the motor 141, and the other end is connected to the scraper 130. The connector 142 drives the scraper 130 to move within a preset angle under the drive of the motor 141. The encoder 143 is connected to the output shaft 1411 of the motor 141. As the output shaft 1411 of the motor 141 rotates synchronously, the encoder 143 records the rotation angle of the output shaft 1411 and feeds it back to the controller, thereby enabling the controller to precisely control the rotation angle of the motor 141.

[0055] In some embodiments, the rotation angle of the output shaft 1411 is 0-30 degrees. The output shaft 1411 can stop at any angle within the range of 0-30 degrees, thereby allowing the scraper 130 to be hovered at any angle within the range of 0-30 degrees. This angle range can be adjusted as needed and is not limited thereto.

[0056] In some embodiments, as shown in FIG4, the gear set 144 further includes a driving gear 1441 and a driven gear 1442. The driving gear 1441 is connected to the output shaft 1411 of the motor to provide active rotational force under the drive of the output shaft 1411. The driven gear 1442 meshes with the driving gear 1441 and drives the connecting member 142 to rotate. The driven gear 1442 can be a complete disc-shaped gear or a part of a disc-shaped gear. The connecting member 142 includes a connecting shaft 1421. The connecting shaft 1421 is fixedly connected to the driven gear 1442 to rotate within a preset angle range under the drive of the driven gear 1442. The connecting member 142 also includes a connecting rod 1422 and a connecting plate 1423. The connecting rod 1422 is coaxially fixedly connected to the connecting shaft 1421. The connecting plate 1423 is disposed on the side of the connecting rod 1422 near the scraper 130. The connecting plate 1423 and the connecting rod 1422 are integrally formed. As the connecting rod 1422 rotates, the connecting plate 1423 rotates within a preset angle. As shown in Figure 4, the base 160 includes a base plate 162. Two front support wheels 170 are mounted on the base plate 162. The support wheels 170 maintain the stability of the roller brush 120 of the cleaning equipment relative to the surface to be cleaned, so as to precisely control the rotation angle of the scraper 130, thereby precisely controlling the downward pressure of the lower scraper 130 or precisely controlling the preset distance between the lower scraper 130 and the surface to be cleaned. The base plate 162 includes a notch for accommodating the connecting plate 1423. When the connecting rod 1422 drives the connecting plate 1423 to rotate upward, the connecting plate 1423 is lifted from the notch of the base plate 162; when the connecting rod 1422 drives the connecting plate 1423 to rotate downward, the connecting plate 1423 returns to the notch of the base plate 162, and is approximately on the same plane as the base plate 162. As shown in Figure 4, the scraper 130 includes a support portion 131 and a contact portion 132. One end of the support portion 131 is fixedly connected to the connecting plate 1423, and the other end is detachably connected to the fitting portion 132. The connecting plate 1423 drives the fitting portion 132 to rotate via the support portion 131. The connecting plate 1423 and the support portion 131 can be an integrally formed structure or a separate structure.

[0057] This disclosure also provides a method for controlling the floor brush of a cleaning device, as shown in Figure 5, including:
