Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a floor brush structure and a cleaning device. BACKGROUND

[0002] With the development of society and the progress of science and technology, more and more intelligent devices are applied to people's life. As a cleaning device that can automatically wipe and clean the ground, the scrubber replaces the mop and other daily cleaning tools, realizes the daily periodic cleaning and on-site cleaning of hard ground, and reduces the housework burden of people, bringing convenience to people's life.

[0003] The scrubber usually includes a roller brush, which can rotate and rub the ground to clean the ground. However, the bristles of the roller brush are prone to unilateral lodging after long-term use, which affects the cleaning effect of the scrubber and is not conducive to the further popularization and application of the scrubber. Utility model content

[0004] Therefore, it is necessary to provide a floor brush structure and a cleaning device aiming at the problem of unilateral lodging of the bristles of the roller brush.

[0005] A floor brush structure includes:

[0006] a main housing;

[0007] a roller brush rotatably mounted on the main housing, the roller brush including a roller brush body and bristles provided on an outer circumferential surface of the roller brush body; and

[0008] a scraping plate mounted on the main housing and located on one side of the roller brush, the scraping plate contacting the bristles;

[0009] wherein the scraping plate reciprocally moves relative to the roller brush to drive the bristles to reciprocally swing around a central axis of the roller brush.

[0010] In one of the embodiments, the scraping plate reciprocally moves relative to the roller brush along a first direction, and the first direction is perpendicular to a radial direction and an axial direction of the roller brush, respectively.

[0011] In one of the embodiments, the floor brush structure further includes a driving structure, the driving structure is in transmission connection with the scraping plate, and the driving structure is used to drive the scraping plate to reciprocally move relative to the roller brush.

[0012] In one of the embodiments, the driving structure includes:

[0013] a driving member;

[0014] a cam mounted on an 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, and drives the scraping plate to reciprocate relative to the rolling brush under the driving of the cam.

[0016] In one of the embodiments, the connecting rod mechanism comprises 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 scraping plate.

[0017] In one of the embodiments, the scraping plate comprises:

[0018] a scraping plate body provided with scraping teeth on the side facing the rolling brush; and

[0019] a first sealing portion and a second sealing portion respectively arranged on opposite sides of the scraping plate body in the width direction and extending along the length direction of the scraping plate body.

[0020] In one of the embodiments, the main housing is provided with a sliding groove, and the scraping plate is limited in the sliding groove.

[0021] A cleaning device comprising the above-mentioned brush structure.

[0023] In one of the embodiments, the cleaning device is a scrubber.

[0024] The above-mentioned brush structure can drive the bristles of the rolling brush to reciprocate around the central axis of the rolling brush through the reciprocating movement of the scraping plate relative to the rolling brush, so as to prevent the bristles from being laid in the same direction and maintain a fluffy state. The fluffy bristles have good scraping effect on dirt on the ground and good absorption effect on water stains on the ground. On the other hand, the rolling brush can always maintain forward rotation during the self-cleaning process, so that the dirt suction pipeline has good absorption effect on the dirt on the rolling brush, and the dirt on the rolling brush will not move away from the dirt suction pipeline due to the reverse rotation of the rolling brush, thereby facilitating the dirt to enter the dirt suction pipeline. In addition, the fluffy bristles can be quickly dried during the drying process of the brush structure, so that the drying efficiency is high, and the reverse rotation of the rolling brush can also be avoided to hinder the hot air from flowing into the dirt suction pipeline.

[0044] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a cleaning device, specifically a floor cleaning machine, which includes 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, and the other end of the handle is provided with a holding portion for a user to hold. The user can move the floor brush structure 100 on the floor by the handle. The main body is arranged at the end of the handle connected to the floor brush structure 100, and is used to absorb and store the sewage generated during the cleaning process.

[0046] In the following embodiments, the forward direction of the cleaning device is defined as the first direction (i.e. the X direction in Figure 1 ), the length direction of the cleaning device is defined as the second direction (i.e. the Y direction in Figure 1 ), and the height direction of the cleaning device is defined as the third direction (i.e. the Z direction in Figure 1 ). The first direction, the second direction, and the third direction are perpendicular to 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 Figures 3 to 5As shown, the floor brush structure 100 comprises 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 a first direction, and comprises a rolling brush 41 rotatably mounted on the main housing 20, which comprises a rolling brush body 412 and brush hairs 414. The rolling brush body 412 is in a cylindrical shape, and the central axis of the rolling brush body 412 extends in a second direction. The brush hairs 414 are covered on the outer circumferential surface of the rolling brush body 412. The rolling brush 41 can continuously rotate in a forward direction (i.e., the rolling brush 41 in Figure 5 rotates in a counterclockwise direction) to wipe and clean dirt on the ground.

[0048] Further, the main housing 20 is also provided with a dirt suction pipeline 20a, and the floor brush structure 100 further comprises a squeegee. The dirt suction pipeline 20a is in communication with a dirt tank of the main body, and the dirt suction port of the dirt suction pipeline 20a faces the rear side of the rolling brush 41. The squeegee is located above the dirt suction port, and is used to press the rolling brush 41 to squeeze out the dirt water in the rolling brush 41. The dirt suction pipeline 20a is used to store the dirt water squeezed out by the squeegee into the dirt tank through the negative pressure effect.

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

[0050] As described in the background, after long-time use, the existing rolling brush 41 has the following problems. On the one hand, the brush hairs 414 will be worn out, which will reduce the water absorption capacity of the rolling brush 41, and increase the water stains on the ground. On the other hand, the long-term pressing of the squeegee on the brush hairs 414 will cause the brush hairs 414 to be unidirectionally laid down and tightly adhere to each other, which will further reduce the cleaning ability and water absorption of the rolling brush 41. Moreover, during the self-cleaning process, the bottom of the brush hairs 414 cannot be effectively cleaned due to the unidirectional laying down and tight adhesion of the brush hairs 414 to each other, which affects the self-cleaning effect.

[0051] In view of the above problems, in some existing technologies, the rolling brush 41 is controlled to alternately rotate in the forward and reverse directions to make the brush hairs 414 fluffy, so as to improve the cleaning effect of the rolling brush 41. However, when the rolling brush 41 is reversed (i.e., the rolling brush 41 in Figure 5 rotates in a clockwise direction), the dirt remaining on the rolling brush 41 will be pushed away from the dirt suction port of the dirt suction pipeline 20a in the opposite direction to the dirt in the cleaning tank of the base station, thereby expanding the range of the dirt, causing some dirt to be too far away from the dirt suction port to be easily absorbed and cleaned, and thus remaining on the front side of the cleaning tank of the base station, which reduces the self-cleaning effect of the cleaning device. Moreover, during the drying process of the cleaning device, the reverse rotation of the rolling 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 Figure 3 ,Figure 6 and Figure 7 In the present application, the brush assembly 40 further comprises a scraping plate 43, which is installed on the main housing 20 and located at one side of the roller brush 41. The scraping plate 43 contacts the bristles 414 of the roller brush 41, and reciprocally moves relative to the roller brush 41 to drive the bristles 414 to reciprocally swing around the central axis of the roller brush 41.

[0053] In this way, through the reciprocating movement of the scraping plate 43 relative to the roller brush 41, the bristles 414 of the roller brush 41 can be driven to reciprocally swing around the central axis of the roller brush 41, thereby preventing the bristles 414 from being laid in the same direction and maintaining a fluffy state. The fluffy bristles 414 have good scraping effect on dirt on the ground and good absorption effect on water stains on the ground, on the one hand, and the roller brush 41 can always maintain forward rotation during the self-cleaning process, so that the dirt on the roller brush 41 has good absorption effect on the dirt suction pipeline 20a, and the dirt on the roller brush 41 will not move away from the dirt suction pipeline 20a due to the reverse rotation of the roller brush 41, thereby facilitating the dirt to enter the dirt suction pipeline 20a. In addition, during the drying process of the brush assembly 40, the fluffy bristles 414 can be quickly dried, so as to have high drying efficiency, and meanwhile, the reverse rotation of the roller brush 41 can be avoided to hinder the hot air flowing into the dirt suction pipeline 20a.

[0054] It can be understood that the scraping plate 43 can drive the bristles 414 to reciprocally swing to maintain the bristles 414 fluffy in different working modes. In some embodiments, when the cleaning device 100 is in a cleaning mode to clean the ground, the scraping plate 43 can be in a reciprocating motion state to drive the bristles 414 to swing during the continuous forward rotation of the roller brush 41, thereby preventing the bristles 414 from being laid during the cleaning process. In some embodiments, when the cleaning device 100 is docked with the base to be in a self-cleaning state, the scraping plate 43 can be in a reciprocating motion state to drive the bristles 414 to swing.

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

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

[0057] Please continue to refer to Figure 6 and Figure 7In some embodiments, the scraping plate 43 comprises a scraping plate body 432. The scraping plate body 432 has a strip-shaped structure, the length direction of the scraping plate body 432 is parallel to the second direction, the width direction of the scraping plate body 432 is parallel to the first direction, and the length of the scraping plate body 432 is equal to or greater than the length of the rolling brush 41. The side of the scraping plate body 432 facing the rolling brush 41 is provided with a plurality of scraping teeth 4321, and all the scraping teeth 4321 are arranged in the width direction of the scraping plate 43 to be in contact with the plurality of bristles 414 to drive the plurality of bristles 414 to swing simultaneously. It can be understood that the number, shape and arrangement of the scraping teeth 4321 are not limited and can be set as required to meet different requirements.

[0058] Further, the scraping plate 43 further comprises 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 in the width direction of the scraping plate body 432 and respectively extend along the length direction of the scraping plate body 432 from one end of the scraping plate body 432 to the other end of the scraping plate body 432. The cross section of the first sealing portion 434 and the second sealing portion 436 perpendicular to the second direction is in the shape of "U". The first sealing portion 434 and the second sealing portion 436 are formed of a material capable of elastic deformation such as rubber, and are used to seal the gap between the rolling brush 41 and the main housing 20 to prevent external dirt from entering the inside of the main housing 20.

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

[0060] As shown in FIG. 1, Figures 6 to 9 In some embodiments, the floor brush assembly 40 further comprises a driving structure 45 in transmission connection with the scraping plate 43, and the driving structure 45 is used to drive the scraping plate 43 to reciprocate.

[0061] Specifically, the driving structure 45 comprises a driving member 452, a cam 454 and a connecting rod mechanism 456. The driving member 452 is installed on the main housing 20, the cam 454 is installed on the output end of the driving member 452, the driving member 452 drives the cam 454 to rotate, and the connecting rod mechanism 456 is connected between the cam 454 and the scraping plate 43. 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 in the third direction, and the driving member 452 outputs torque through the output shaft to drive the cam 454 to rotate around the third direction.

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

[0064] Further, the driving structure 45 further comprises a cam bearing 458, the inner ring of the cam bearing 458 is sleeved on the outside of 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 arranged on the main housing 20 about the central axis thereof through the cam bearing 458, and rotates about the central axis thereof under the driving 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 main body 432 of the scraping plate. Therefore, the rotation of the driving member 452 is converted into the reciprocating linear movement of the connecting rod mechanism 456 along the first direction by the cam 454.

[0066] Specifically, the connecting rod mechanism 456 comprises a first connecting rod 4561 and a second connecting rod 4563. The first connecting rod 4561 is in a rod structure, one end of the first connecting rod 4561 is rotatably connected to the connecting shaft 4545 of the cam 454 about the first direction through a bearing or the like, and the other end of the first connecting rod 4561 is rotatably connected to the second connecting rod 4563 about the first direction through a bearing or the like. The second connecting rod 4563 is in a “T” shape structure, comprising a first connecting part 4563a and a second connecting part 4563b which are integrally formed. The first connecting part 4563a is in a rod structure, one end of the first connecting part 4563a is rotatably connected to the first connecting rod 4561 about the first direction through a bearing or the like, and the other end of the first connecting part 4563a is connected to the second connecting part 4563b. The second connecting part 4563b is in a long strip structure, the length direction of the second connecting part 4563b is parallel to the second direction, and the first connecting part 4563a is connected to the middle region of the second connecting part 4563b in the length direction thereof.

[0067] Further, the scraping plate body 432 is provided with a plurality of first hinge portions 4323 on the side away from the roller brush 41, and all the first hinge portions 4323 are arranged at intervals along the length direction of the scraping plate body 432. The second connecting portion 4563b is provided with a plurality of second hinge portions 4563c, and all the second hinge portions 4563c are arranged at intervals along the length direction of the second connecting portion 4563b. Each second hinge portion 4563c is rotatably connected with a first hinge portion 4323 through a hinge shaft around the second direction. It can be understood that the number of the first hinge portions 4323 and the second hinge portions 4563c is not limited, and can be set according to different connection requirements.

[0068] In this way, the driving member 452 outputs torque to drive the cam 454 to rotate around its own axis, 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 further driving the other end of the first connecting rod 4561 to reciprocate in the first direction, thereby driving the second connecting rod 4563 to reciprocate in the first direction, and finally driving the scraping plate 43 to reciprocate in the first direction.

[0069] The brush structure 100 and the cleaning equipment provided with the same can drive the bristles 414 to swing back and forth through the reciprocating scraping plate 43, so that the bristles 414 can always maintain a fluffy state, thereby having good scraping effect and water stain absorption effect when cleaning the ground. When the brush structure 100 is self-cleaning, the deep dirt of the fluffy bristles 414 can also be easily cleaned, and the bristles 414 can be fluffy without driving the roller brush 41 to reverse, so that the process of sucking dirt by the dirt suction pipeline 20a is continuous, and has good cleaning effect. Moreover, the bristles 414 can be quickly dried, and have high drying efficiency.

[0070] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure.

[0071] 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 considered as a limitation on the patent application scope. It should be noted that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
