[0002] With the development of society and the advancement of science and technology, more and more smart devices are being used in people's lives. As a cleaning device that can automatically wipe and clean the floor, the floor scrubber replaces daily cleaning tools such as mops, and realizes daily periodic cleaning and fixed-point cleaning of hard floors at any time, which reduces people's housework burden and brings convenience to people's lives.

[0003] A floor scrubber usually includes a roller brush, which can clean the floor by rotating and rubbing against the floor. However, after long-term use, the bristles of the roller brush are prone to one-way lodging, thereby affecting the cleaning effect of the floor scrubber and hindering the further promotion and application of the floor scrubber. Summary of the invention

[0004] Based on this, it is necessary to provide a floor brush structure and cleaning equipment to address the problem of one-way lodging of the bristles of the roller brush.

[0005] A floor brush structure, comprising:

[0006] main housing;

[0007] A roller brush is rotatably mounted on the main housing, the roller brush comprising a roller brush body and bristles arranged on an outer circumferential surface of the roller brush body; and

[0008] A scraper plate is mounted on the main housing and located on one side of the roller brush, wherein the scraper plate contacts a portion of the brush hairs;

[0009] Wherein, the scraping plate moves back and forth relative to the roller brush to drive the bristles to swing back and forth around the central axis of the roller brush.

[0010] In one of the embodiments, the scraper plate reciprocates relative to the roller brush along a first direction, and the first direction is perpendicular to the radial direction and the axial direction of the roller brush.

[0011] In one of the embodiments, the floor brush structure further includes a driving structure, which is transmission-connected to the scraping plate, and is used to drive the scraping plate to reciprocate relative to the roller brush.

[0012] In one embodiment, the driving structure includes:

[0013] Driving parts;

[0014] A cam is mounted on the output end of the driving member, and the driving member drives the cam to rotate; and

[0015] A connecting rod mechanism is connected between the cam and the scraping plate. The connecting rod mechanism drives the scraping plate to move back and forth relative to the roller brush under the drive of the cam.

[0016] In one embodiment, the connecting rod mechanism includes a first connecting rod and a second connecting rod, one end of the first connecting rod is rotatably connected to the cam, the other end of the first connecting rod is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the scraper plate.

[0017] In one embodiment, the scraper plate comprises:

[0018] A scraper plate body, with scraper teeth on one side facing the roller brush; and

[0019] The first sealing portion and the second sealing portion are respectively arranged on two opposite sides of the scraper plate body in the width direction and extend along the length direction of the scraper plate body.

[0020] In one of the embodiments, the main shell is provided with a sliding groove, and the scraper plate is confined in the sliding groove.

[0023] In one embodiment, the cleaning device is a floor scrubber.

[0024] The above-mentioned floor brush structure can drive the bristles of the roller brush to swing back and forth around the central axis of the roller brush through the reciprocating movement of the scraper plate relative to the roller brush, thereby preventing the bristles from falling in the same direction and maintaining a fluffy state. On the one hand, the fluffy bristles have a good scraping effect on the dirt on the ground and a good absorption effect on the water stains on the ground. On the other hand, the roller brush can always keep forward rotation during the self-cleaning process, so the dirt suction pipeline has a good absorption effect on the dirt on the roller brush, and the dirt on the roller brush will not be far away from the dirt suction pipeline due to the reversal of the roller brush, so that the dirt is easy to enter the dirt suction pipeline. In addition, during the drying process of the floor brush structure, the fluffy bristles can be dried quickly, so it has a higher drying efficiency, and it can also avoid the reversal of the roller brush hindering the hot air from flowing into the dirt suction pipeline.

[0044] 1 and 2 , an embodiment of the present application provides a cleaning device, specifically a floor scrubber, including a floor brush structure 100 , a handle, and a main body.

[0045] The floor brush structure 100 is used to clean the floor. One end of the handle is connected to the floor brush structure 100. The other end of the handle is provided with a gripping portion for the user to hold. The user can drive the floor brush structure 100 to move on the floor through the handle. The main body is provided at one end of the handle connected to the floor brush structure 100, and is used to absorb and store sewage generated during the cleaning process.

[0046] In the following embodiments, the forward direction of the cleaning device is set as the first direction (i.e., the X direction in Figure 1), the length direction of the cleaning device is set as the second direction (i.e., the Y direction in Figure 1), and the height direction of the cleaning device is set as the third direction (i.e., the Z direction in Figure 1). The first direction, the second direction, and the third direction intersect with each other. As a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other.

[0047] As shown in FIGS. 3 to 5 , the floor brush structure 100 includes a main housing 20 and a floor brush assembly 40. The floor brush assembly 40 is mounted on one side of the main housing 20 in the first direction. The floor brush assembly 40 includes a roller brush 41, which is rotatably mounted on the main housing 20 and includes a roller brush body 412 and bristles 414. The roller brush body 412 is cylindrical, and the central axis of the roller brush body 412 extends along the second direction. The bristles 414 cover the outer circumferential surface of the roller brush body 412. The roller brush 41 can continuously rotate in the forward direction (i.e., the roller brush 41 in FIG. 5 rotates in the counterclockwise direction) to wipe and clean the dirt on the floor.

[0048] Furthermore, the main housing 20 is further provided with a sewage suction pipeline 20a, and the floor brush structure 100 further includes a wiper. The sewage suction pipeline 20a is connected to the sewage tank of the main body, the sewage suction port of the sewage suction pipeline 20a faces the rear side of the roller brush 41, and the wiper is located above the sewage suction port. The wiper is used to squeeze the roller brush 41 to squeeze out the sewage in the roller brush 41, and the sewage suction pipeline 20a is used to suck the sewage squeezed out by the wiper through the negative pressure and store it in the sewage tank.

[0049] In some embodiments, the cleaning device can also cooperate with a base station, which can charge the cleaning device, extract sewage, and replenish clean water. The floor brush structure 100 can also perform self-cleaning in the base station for the next use.

[0050] As described in the background technology, after long-term use, the existing roller brush 41 will have its bristles 414 worn out, which will reduce the water absorption capacity of the roller brush 41 and increase the residual water stains on the ground. On the other hand, the long-term squeezing of the bristles 414 by the wiper will cause the bristles 414 to fall down one-way and stick to each other, thereby further reducing the cleaning ability and water absorption of the roller brush 41. Moreover, during the self-cleaning process, since the bristles 414 fall down one-way and stick to each other, the bottom of the bristles 414 cannot be effectively cleaned, affecting the self-cleaning effect.

[0051] In view of the above problems, in some prior arts, the roller brush 41 is controlled to rotate alternately forward and reversely to make the bristles 414 fluffy, thereby improving the cleaning effect of the roller brush 41. However, when the roller brush 41 is reversed (i.e., the roller brush 41 in FIG. 5 rotates clockwise), the dirt remaining on it and the dirt in the base station cleaning tank will be pushed away from the suction port of the dirt suction pipeline 20a in the opposite direction, thereby expanding the range of dirt, causing some dirt to be too far away from the suction port and not easily absorbed and cleaned, and then remaining on the front side of the base station cleaning tank, reducing the self-cleaning effect of the cleaning device. Moreover, in the process of drying the cleaning device, the reversal of the roller brush 41 will hinder the hot air from flowing into the dirt suction pipeline 20a, thereby affecting the drying effect.

[0052] Based on the above technical problems, please refer to Figures 3, 6 and 7. The floor brush assembly 40 in the present application also has a scraper plate 43, which is installed on the main shell 20 and is located on one side of the roller brush 41. The scraper plate 43 contacts part of the bristles 414 of the roller brush 41. The scraper plate 43 reciprocates relative to the roller brush 41 to drive the bristles 414 to swing back and forth around the central axis of the roller brush 41.

[0053] In this way, the reciprocating movement of the scraper plate 43 relative to the roller brush 41 can drive the bristles 414 of the roller brush 41 to swing back and forth around the central axis of the roller brush 41, thereby preventing the bristles 414 from falling in the same direction and maintaining a fluffy state. On the one hand, the fluffy bristles 414 have a good scraping effect on the dirt on the ground and a good absorption effect on the water stains on the ground. On the other hand, the roller brush 41 can always keep forward rotation during the self-cleaning process, so the dirt suction pipeline 20a has a good absorption effect on the dirt on the roller brush 41, and the dirt on the roller brush 41 will not be away from the dirt suction pipeline 20a due to the reversal of the roller brush 41, so that the dirt is easy to enter the dirt suction pipeline 20a. In addition, during the drying process of the floor brush assembly 40, the fluffy bristles 414 can be dried quickly, so it has a higher drying efficiency, and it can also avoid the reversal of the roller brush 41 hindering the hot air from flowing into the dirt suction pipeline 20a.

[0054] It is understood that the scraper plate 43 can drive the bristles 414 to swing back and forth in different working modes to keep the bristles 414 fluffy. In some embodiments, when the cleaning device 100 is in the cleaning mode to clean the floor, the scraper plate 43 can be in a reciprocating motion state to drive the bristles 414 to swing while the roller brush 41 is continuously rotating in the forward direction, thereby preventing the bristles 414 from falling over during the cleaning process. In some embodiments, when the cleaning device 100 is docked with the base and is in a self-cleaning state, the scraper plate 43 can be in a reciprocating motion state to drive the bristles 414 to swing.

[0055] As a preferred embodiment, the scraper plate 43 moves linearly and reciprocatingly along a first direction relative to the roller brush 41, so the moving direction of the scraper plate 43 is respectively perpendicular to a radial direction and an axial direction of the roller brush 41, thereby having a good fluffing effect.

[0056] It is understood that the moving direction of the scraper plate 43 is not limited thereto. For example, in some other embodiments, the scraper plate 43 reciprocates around the central axis of the roller brush 41, and the moving track of the scraper plate 43 is arc-shaped, which can also play the role of fluffing the bristles 414. In other embodiments, the moving direction of the scraper plate 43 may not be completely perpendicular to a radial direction and an axial direction of the roller brush 41, but may be offset within a certain range, which can also play the role of fluffing the bristles 414.

[0057] Please continue to refer to Figures 6 and 7. In some embodiments, the scraper plate 43 includes a scraper plate body 432. The scraper plate body 432 is in a long strip structure, the length direction of the scraper plate body 432 is parallel to the second direction, the width direction of the scraper plate body 432 is parallel to the first direction, and the length of the scraper plate body 432 is equal to or greater than the length of the roller brush 41. A plurality of scraper teeth 4321 are provided on the side of the scraper plate body 432 facing the roller brush 41, and all the scraper teeth 4321 are arranged at intervals along the width direction of the scraper plate 43 to contact with the multiple bristles 414 to drive the multiple bristles 414 to swing simultaneously. It can be understood that the number, shape and arrangement of the scraper teeth 4321 are not limited thereto, and can be set as needed to meet different requirements.

[0058] Furthermore, the scraper plate 43 also includes a first sealing portion 434 and a second sealing portion 436. The first sealing portion 434 and the second sealing portion 436 are respectively arranged on opposite sides of the scraper plate body 432 in the width direction, and extend from one end of the scraper plate body 432 to the other end of the scraper plate body 432 along the length direction of the scraper plate body 432, respectively. The cross-section of the first sealing portion 434 and the second sealing portion 436 perpendicular to the second direction is "U"-shaped. The first sealing portion 434 and the second sealing portion 436 are formed of elastically deformable materials such as rubber, and the first sealing portion 434 and the second sealing portion 436 are used to close the gap between the roller brush 41 and the main housing 20, and play a sealing role to prevent external dirt from entering the interior of the main housing 20.

[0059] In some embodiments, the main shell 20 is further provided with a guide groove extending along the second direction, and the scraping plate 43 is limited in the guide groove to move back and forth in the guide groove, thereby ensuring a good fluffing effect.

[0060] As shown in FIG. 6 to FIG. 9 , in some embodiments, the floor brush assembly 40 further includes a driving structure 45 , which is transmission-connected to the scraping plate 43 , and the driving structure 45 is used to drive the scraping plate 43 to move back and forth.

[0061] Specifically, the driving structure 45 includes a driving member 452, a cam 454, and a connecting rod mechanism 456. The driving member 452 is mounted on the main housing 20, the cam 454 is mounted on the output end of the driving member 452, the driving member 452 drives the cam 454 to rotate, the connecting rod mechanism 456 is connected between the cam 454 and the scraping plate 43, and the connecting rod mechanism 456 drives the scraping plate 43 to reciprocate under the drive of the cam 454.

[0062] The driving member 452 is a motor, which is fixedly installed in the main housing 20. The output shaft of the driving member 452 is inserted into one end of the cam 454 along the third direction. The driving member 452 outputs torque through the output shaft, thereby driving the cam 454 to rotate around the third direction.

[0063] The cam 454 includes a first rotating portion 4541, a second rotating portion 4543, and a connecting shaft 4545. The first rotating portion 4541 and the second rotating portion 4543 are connected to each other and are coaxially arranged, and the central axes of the two extend along the third direction. The first rotating portion 4541 is sleeved on the output shaft of the driving member 452, and the outer diameter of the second rotating portion 4543 is larger than the outer diameter of the first rotating portion 4541. The connecting shaft 4545 is convexly arranged at one end of the second rotating portion 4543 away from the first rotating portion 4541, and the connecting shaft 4545 is eccentrically arranged relative to the second rotating portion 4543 and close to the edge of the second rotating portion 4543.

[0064] Furthermore, the driving structure 45 also includes a cam bearing 458, the inner ring of the cam bearing 458 is sleeved outside the first rotating part 4541, and the outer ring of the cam bearing 458 is fixedly connected to the main housing 20. Therefore, the cam 454 is rotatably installed on the main housing 20 around its own central axis through the cam bearing 458, and rotates around its own central axis under the drive of the driving member 452.

[0065] One end of the connecting rod mechanism 456 is rotatably connected to the eccentrically arranged connecting shaft 4545, and the other end of the connecting rod mechanism 456 is rotatably connected to the scraper plate body 432, so that the rotation of the driving member 452 is converted by the cam 454 into reciprocating linear movement of the connecting rod mechanism 456 along the first direction.

[0066] Specifically, the connecting rod mechanism 456 includes a first connecting rod 4561 and a second connecting rod 4563. The first connecting rod 4561 is a rod-shaped structure, one end of the first connecting rod 4561 is rotatably connected to the connecting shaft 4545 of the cam 454 around a first direction through a bearing or other components, and the other end of the first connecting rod 4561 is rotatably connected to the second connecting rod 4563 around a first direction through a bearing or other components. The second connecting rod 4563 is a "T"-shaped structure, including an integrally formed first connecting portion 4563a and a second connecting portion 4563b. The first connecting portion 4563a is a rod-shaped structure, one end of the first connecting portion 4563a is rotatably connected to the first connecting rod 4561 around a first direction through a bearing or other components, and the other end of the first connecting portion 4563a is connected to the second connecting portion 4563b. The second connection portion 4563b is in a long strip structure, the length direction of the second connection portion 4563b is parallel to the second direction, and the first connection portion 4563a is connected to the middle area of ​​the second connection portion 4563b in its own length direction.

[0067] Further, a plurality of first hinged parts 4323 are convexly provided on the side of the scraper plate body 432 facing away from the roller brush 41, and all the first hinged parts 4323 are arranged at intervals along the length direction of the scraper plate body 432. The second connecting part 4563b is provided with a plurality of second hinged parts 4563c, and all the second hinged parts 4563c are arranged at intervals along the length direction of the second connecting part 4563b, and each second hinged part 4563c is rotatably connected to a first hinged part 4323 around a second direction via a hinge axis. It can be understood that the number of the first hinged parts 4323 and the second hinged parts 4563c is not limited, and can be set as needed to meet different connection requirements.

[0068] In this way, the driving member 452 outputs torque to drive the cam 454 to rotate around its own axis, and the connecting shaft 4545 on the cam 454 rotates around the central axis of the cam 454, thereby driving one end of the first connecting rod 4561 to rotate around the central axis of the cam 454, and then making the other end of the first connecting rod 4561 reciprocate in the first direction, thereby driving the second connecting rod 4563 to reciprocate in the first direction, and finally driving the scraper plate 43 to reciprocate in the first direction.

[0069] The above-mentioned floor brush structure 100 and the cleaning equipment equipped with it, through the reciprocating scraping plate 43, drive the bristles 414 to swing back and forth, so that the bristles 414 can always remain fluffy, so that when cleaning the floor, it has a good scraping effect and water stain absorption effect. When the floor brush structure 100 is self-cleaning, the deep dirt of the fluffy bristles 414 is also easy to clean, and there is no need to drive the roller brush 41 to reverse to make the bristles 414 fluffy. Therefore, the process of absorbing dirt by the suction pipe 20a is continuous, with a good cleaning effect, and the bristles 414 can be quickly dried with a high drying efficiency.

[0070] 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.

[0071] 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.
