[0002] With the development of economy and the progress of society, people have higher and higher requirements for the quality of life. Therefore, some smart appliances that can free people's hands have emerged. Among them, sweeping robots, as a kind of smart home appliances, play an increasingly important role in people's daily lives.

[0003] A sweeping robot generally includes a dust collection system, a travel system, and a power supply system. The dust collection system is used to collect dust on the ground, the travel system is used to drive the sweeping robot to move, and the power supply system is used to provide energy for the dust collection system and the travel system. Generally, the dust collection system includes a roller brush mechanism, which includes a housing, a roller brush assembly, and a roller brush cover. The roller brush assembly is located within the housing, and the roller brush cover is located on the housing. The roller brush cover is provided with a dust suction port that allows the roller brush assembly to contact the ground. When the roller brush assembly rotates, the dust is drawn up through the dust suction port for cleaning. However, after using for a period of time, the traditional roller brush assembly is easily stuck due to excessive hair entanglement, and the roller brush assembly is inconvenient to clean, which in turn affects the normal operation of the roller brush assembly. Summary of the Invention

[0004] In order to solve the problem that the roller brush assembly is easily entangled with hair and is inconvenient to clean, the present invention proposes a roller brush assembly, a roller brush mechanism and a sweeping robot. The roller brush assembly, the roller brush mechanism and the sweeping robot can achieve the technical effect of preventing the roller brush assembly from being entangled with hair and facilitating cleaning.

The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] In one embodiment of the present invention, a sweeping robot is provided, which includes a dust collection system, a walking system and a power supply system. The dust collection system is used to collect dust on the ground, the walking system is used to drive the sweeping robot to move, and the power supply system is used to provide working energy for the dust collection system and the walking system.

[0039] The dust collection system includes a roller brush mechanism, a dust box, an air duct and a fan. The dust box is connected to the outlet of the roller brush mechanism, and the air duct is connected between the dust box and the fan. When the roller brush mechanism is working, it picks up the dust on the ground, and then the suction force generated by the fan sucks the dust-mixed air into the interior of the sweeping robot. When the dust-mixed airflow passes through the dust box, the dust is filtered in the dust box, and the clean air is discharged from the air duct after passing through the fan, thus realizing the dust collection function.

[0040] See Figure 1 The roller brush mechanism 200 includes a shell (not shown), a roller brush assembly 100 and a roller brush cover 210. The roller brush cover 210 is coupled to the shell and encloses a roller brush cavity. The roller brush assembly 100 is disposed in the roller brush cavity so that the roller brush assembly 100 can be assembled and protected by the roller brush cavity. Specifically, the shell has an opening, through which the roller brush assembly 100 is disposed in the shell. The roller brush cover 210 is disposed at the opening and coupled to the shell. In this way, a roller brush cavity is enclosed between the shell and the roller brush cover 210 so that the roller brush assembly 100 can be assembled in the roller brush cavity. In addition, a dust suction port 211 connected to the roller brush cavity is provided on the roller brush cover 210. The roller brush assembly 100 can contact the ground through the dust suction port 211 to pick up dust and other garbage on the ground, and then the garbage is sucked into the sweeping robot through negative pressure to complete the vacuuming work.

[0041] See Figure 2-Figure 3 The roller brush assembly 100 includes a roller body 10 and a brush body 30. The roller body 10 is connected to a motor, and the brush body 30 is disposed on the surface of the roller body 10. When the motor is operating, the roller body 10 rotates about its own axis, thereby rotating the brush body 30 on the surface of the roller body 10. The rotating brush body 30 contacts the ground, picking up dust and other debris on the ground to perform cleaning. Specifically, the brush body 30 includes a rubber brush 50 and a bristle brush 70. Along the rotation direction a of the roller body 10, the bristle brush 70 has a windward side 71 and a leeward side 73. The rubber brush 50 is located on the windward side 71 and abuts against the bristle brush 70. The windward side 71 is located in front of the bristle brush 70 in the rotation direction a, and the leeward side 73 is located behind the bristle brush 70 in the rotation direction a. This is equivalent to placing the brush 70 first and then the rubber brush 50 in the rotation direction a of the roller body 10. In the rotation direction a, the rubber brush 50 is located in front of the brush 70, and the rubber brush 50 is against the windward side 71 of the brush. During the rotation of the roller body 10, the rubber brush 50 against the brush 70 first contacts the ground, blocking hair on the ground and preventing the hair from being entangled with the brush 70. This reduces hair entanglement, prevents the roller brush assembly 100 from getting stuck due to hair entanglement, and improves the working efficiency of the roller brush assembly 100.

[0042] Furthermore, the distance between the side of the brush 70 away from the roller body 10 and the roller body 10 is greater than the distance between the side of the rubber brush 50 away from the roller body 10 and the roller body 10. In other words, the brush 70 partially protrudes from the rubber brush 50, and the rubber brush blocks hair to prevent it from getting entangled in the brush 70. At the same time, the brush 70 at least partially protrudes from the rubber brush, and the portion of the brush 70 protruding relative to the rubber brush 50 contacts the ground to perform cleaning work.

[0043] As can be understood, the portion of the brush 70 that protrudes from the rubber brush 50 has an interference fit with the ground. During the rotation of the roller brush assembly 100, the rubber brush 50 first cleans hair and other debris from the ground. Then, the brush 70 located behind the rubber brush 50 contacts the ground. When the brush 70 contacts the ground, due to the interference fit between the brush 70 and the ground, the brush 70 is bent in a direction opposite to the rotation direction a by the action of the ground, that is, the brush 70 bends away from the rubber brush 50. After bending, the brush 70 can be completely located behind the rubber brush 50, and the rubber brush 50 can still prevent hair from being entangled in the brush 70. Therefore, although the brush 70 is partially protruding from the rubber brush 50 to facilitate the cleaning of dust and other debris from the ground, the brush 70 will bend away from the rubber brush 50 during the cleaning process. The top portion of the brush 70 that protrudes from the rubber brush 50 can still bend behind the rubber brush 50, and the rubber brush 50 can still protect the top of the brush 70, preventing hair from being entangled.

[0044] See Figure 3-Figure 6In some embodiments, the brush 70 is detachable from the roller body 10. This allows the brush body 30 to have two states. In one state, the brush body 30 includes the brush 70 and the rubber brush 50. The rubber brush 50 can be used to clean not only large particles of waste, such as soybeans, but also small particles of waste, such as dust. This allows the rubber brush 50 and the brush 70 to work together to comprehensively clean the floor, achieving a superior cleaning effect. In the other state, the brush 70 is detached, leaving the brush body 30 consisting solely of the rubber brush 50. This allows for cleaning large particles of waste. In this case, the brush 70 can be detached, allowing the rubber brush 50 to clean the waste, while the rubber brush 50 can be used to clean the waste. This prevents contamination of the brush 70, improving its utilization. This allows the brush body 30 to have multiple states. Furthermore, the detachable design of the brush 70 from the rubber brush facilitates cleaning.

[0045] See Figure 2 and Figure 5 In some embodiments, the rubber brush 50 includes a surrounding portion 52 and a stop portion 54. The surrounding portion 52 surrounds the base of the brush 70 and is disposed within the first mounting groove 11. The stop portion 54 is connected to the surrounding portion 52. The stop portion 54 is located on the windward side 71 of the brush 70 and abuts against the brush 70. Thus, by providing the surrounding portion 52 on the rubber brush 50, the base of the brush 70 is surrounded by the surrounding portion 52, and the brush 70 is then assembled to the rubber brush 50, so that the rubber brush 50 and the brush 70 are assembled as a whole. Subsequently, the brush body 30 can be assembled by simply assembling the rubber brush 50 to the roller body 10, eliminating the need to assemble the rubber brush 50 and the brush 70 separately, thereby improving assembly efficiency. Furthermore, the surrounding portion 52 surrounds the base of the brush 70, providing a certain amount of support for the brush 70, preventing the brush 70 from shifting or deforming during cleaning, and ensuring the cleaning effect of the brush 70.

[0046] The distance between the side of the stopper 54 away from the roller body 10 and the roller body 10 is smaller than the distance between the side of the brush 70 away from the roller body 10, so that the end of the brush 70 protrudes from the stopper 54. During the rotation of the roller brush assembly 100, the rubber brush 50 first cleans the ground to remove large particles of garbage such as soybeans, and then the protruding end of the brush 70 behind the rubber brush 50 cleans the ground to remove small particles of garbage such as dust.

[0047] In some embodiments, the roller body 10 is provided with a first mounting slot 11; the enclosing portion 52 is positionally mounted within the first mounting slot 11 in a direction perpendicular to the axial direction of the roller body 10. This allows the enclosing portion 52 to be installed through the first mounting slot 11, while also being positionally secured in a direction perpendicular to the axial direction of the roller body 10, preventing it from falling out of the first mounting slot 11 in the direction perpendicular to the roller body 10, thereby ensuring reliable installation. Furthermore, the enclosing portion 52 encloses a receiving slot 521, into which the base of the brush 70 is positioned. The engagement of the receiving slot 521 with the base of the brush 70 allows the brush 70 to be assembled to the rubber brush 50. In addition, the root of the brush 70 is limitedly assembled in the accommodating cavity 521 along a direction perpendicular to the axial direction of the roller body 10, so that when the root of the brush 70 is assembled through the accommodating cavity 521, the root of the brush 70 is limited by the inner wall of the accommodating cavity 521 to prevent the brush 70 from separating from the rubber brush 50 along a direction perpendicular to the roller body 10, thereby ensuring the installation effect.

[0048] Furthermore, the rubber brush 50 further includes an auxiliary portion 56, which is connected to the surrounding portion 52. The auxiliary portion 56 is located on the leeward side 73 and abuts the brush 70. The distance between the auxiliary portion 56 and the roller body 10 on the side away from the roller body 10 is less than the distance between the blocking portion 54 and the roller body 10 on the side away from the roller body 10. The auxiliary portion 56 blocks the leeward side 73 of the brush 70 relative to the blocking portion 54 and is relatively low. The auxiliary portion 56 provides a certain amount of support for the leeward side 73 of the brush 70. When the brush 70 is bent by the force of the ground, the auxiliary portion 56 supports the end of the brush 70 close to the roller body 10, preventing the brush 70 from bending too much and deforming after excessive bending, thereby ensuring the cleaning effect of the brush 70.

[0049] Specifically in this embodiment, a through slot 57 is formed between the auxiliary portion 56 and the stopper portion 54, communicating with the accommodating groove 521. In a plane perpendicular to the axial direction of the roller body 10, and perpendicular to the direction from the surrounding portion 52 to the stopper portion 54, the width of the through slot 57 is smaller than the width of the accommodating groove 521. Furthermore, the brush 70 includes a brush body 72 and a stopper portion 74. The stopper portion 74 is connected to the brush body 72 and is positioned within the accommodating groove 521 along the direction from the surrounding portion 52 to the stopper portion 54. The brush body 72 extends outward through the through slot 57. That is, the width of the through slot 57 is relatively small, the width of the accommodating slot 521 is relatively large, the width of the limiting portion 74 is relatively large, and the width of the brush body 72 is relatively small. During installation, the limiting portion 74 is inserted into the accommodating slot 521, and the brush body 72 extends out of the through slot 57. This allows the limiting portion 74 to contact the inner wall of the accommodating slot 521, preventing the brush 70 from separating from the rubber brush 50 along the direction from the surrounding portion 52 to the abutting portion 54, thereby reliably assembling the brush 70 to the rubber brush 50. Specifically, the cross-section of the brush 70 and the accommodating slot 521 are both T-shaped.

[0050] Optionally, the root of the brush 70 can be detachably assembled in the accommodating groove 521. When in use, the brush 70 can be assembled or disassembled as needed, providing the brush body 30 in multiple states, and the brush 70 is easy to clean after being disassembled.

[0051] Specifically, the accommodating groove 521 and the through groove 57 are provided through the extension direction of the rubber brush 50 to form a first mounting opening at the extended end of the rubber brush 50. The brush 70 can be assembled into the accommodating groove 521 of the surrounding portion 52 along the extension direction of the rubber brush 50 from the first mounting opening, thereby achieving assembly of the rubber brush 50 with the brush 70. Similarly, the brush 70 can also be removed from the accommodating groove 521 from the first mounting opening, thus achieving detachable assembly of the brush 70 with the rubber brush 50.

[0052] Alternatively, the enclosing portion 52 may be detachably disposed within the first mounting groove 11 of the roller body 10, thereby allowing the rubber brush 50 and the bristle brush 70 to be removed from the roller body 10 as a whole, thereby facilitating cleaning of the rubber brush 50 and the bristle brush 70. Specifically, in a plane perpendicular to the axial direction of the roller body 10, the enclosing portion 52 protrudes relative to the bristle brush 54 along a width direction perpendicular to the direction in which the enclosing portion 52 points toward the bristle brush 54. The enclosing portion 52 is disposed within the first mounting groove 11. An opening is provided on the top wall of the first mounting groove 11 facing the axis of the roller body 10, through which the bristle brush 54 and the bristle brush 54 extend. The top wall of the first mounting groove 11 abuts against the side of the enclosing portion 52 facing away from the bottom wall of the first mounting groove 11, equivalent to the protruding portion of the enclosing portion 52 relative to the bristle brush 54 abutting against the top wall of the first mounting groove, thereby preventing the rubber brush 50 from escaping from the first mounting groove 11 in the direction in which the enclosing portion 52 points toward the bristle brush 54, thereby improving the reliability of the installation of the brush body 30. Specifically, the transverse cross-sections of the surrounding portion 52 and the first installation groove 11 are both T-shaped.

[0053] Furthermore, the first mounting groove 11 is provided through the roller body 10 along the extension direction of the rubber brush 50, thereby forming a second mounting opening at the axial end of the roller body 10. The rubber brush 50 can be assembled into the first mounting groove 11 from the second mounting opening along the extension direction of the first mounting groove 11, thereby achieving assembly of the rubber brush 50 and the roller body 10. Similarly, the rubber brush 50 can also be removed from the first mounting groove 11 from the second mounting opening, thus achieving detachable assembly of the rubber brush 50 and the first mounting groove 11.

[0054] In other embodiments, a second mounting groove is provided on the roller body 10, and the root of the rubber brush 50 and the root of the hair brush 70 are assembled side by side in the second mounting groove, that is, the hair brush 70 and the rubber brush 50 are arranged side by side in the second mounting groove. In this way, there is no need to set a structure for installing the hair brush 70 on the rubber brush 50, which simplifies the overall structure of the rubber brush 50 and facilitates the production of the rubber brush 50.

[0055] Furthermore, the base of the brush 70 is bonded to the base of the rubber brush 50. This bonding facilitates their simultaneous installation into the second mounting groove. Furthermore, the bonded brush 70 and rubber brush 50 prevent them from shifting within or detaching from the second mounting groove, thereby improving the installation reliability of the brush 70 and rubber brush 50. Optionally, the bases of both the brush 70 and rubber brush 50 are bonded to the inner wall of the second mounting groove to securely secure the brush 70 and rubber brush 50 within the second mounting groove.

[0056] It is understandable that in some other embodiments, the brush 70 and the rubber brush 50 can also be assembled to the roller body 10 in other ways. The installation method of the brush 70 and the rubber brush 50 is not limited here, as long as the rubber brush 50 can be supported on the windshield side of the brush 70.

[0057] In some embodiments, multiple brush bodies 30 are arranged at intervals along the circumference of the roller body 10. Multiple brush bodies 30 are arranged at intervals along the circumference of the roller body 10. When the roller body 10 rotates, the multiple brush bodies 30 clean the floor, improving the cleaning effect. Each brush strip and brush 70 extends in a wavy or V-shaped pattern from one end to the other along the axis of the roller body 10. The extension path of the brush strips and brushes 70 is not limited herein.

[0058] Based on the same concept, one embodiment of the present invention further provides a roller brush mechanism as described above. The roller brush mechanism includes a housing, a roller brush assembly 100, and a roller brush cover. The housing has an opening, and the roller brush assembly 100 is disposed within the housing through the opening. The roller brush cover is disposed at the opening and is mated to the housing. Thus, a housing space is enclosed between the housing and the roller brush cover, and the roller brush assembly 100 is assembled within the housing space. Furthermore, a dust suction port is provided on the roller brush cover, through which the roller brush assembly 100 can contact the ground to pick up dust and other debris on the ground. The debris is then sucked into the sweeping robot through negative pressure, completing the vacuuming process.

[0059] Specifically, the roller brush assembly 100 includes a roller body 10 and a brush body 30. The roller body 10 is connected to a motor, and the brush body 30 is located on the surface of the roller body 10. When the motor is operating, it drives the roller body 10 to rotate about its own axis, thereby driving the brush body 30 on the surface of the roller body 10 to rotate. The rotating brush body 30 contacts the ground, picking up dust and other debris on the ground to perform cleaning. Specifically, the brush body 30 includes a rubber brush 50 and a bristle brush 70. Along the rotation direction a of the roller body 10, the bristle brush 70 has a windward side 71 and a leeward side 73. The windward side 71 is located in front of the bristle brush 70 in the rotation direction a, and the leeward side 73 is located behind the bristle brush 70 in the rotation direction a. The rubber brush 50 and the bristle brush 70 are located side by side on the outer surface of the roller body 10, and the bristle brush 70 and the rubber brush 50 are arranged in sequence along the rotation direction a of the roller body 10. In the rotational direction a of the roller body 10, the brush 70 is positioned first, followed by the rubber brush 50. In this direction a, the rubber brush 50 is positioned in front of the brush 70, and the rubber brush 50 rests on the windward side 71 of the brush. During the rotation of the roller body 10, the rubber brush 50 in the front first contacts the ground, blocking any hair on the ground and preventing it from becoming entangled with the brush 70. This reduces hair entanglement, prevents the roller brush assembly 100 from becoming stuck due to hair entanglement, and improves its operating efficiency. Furthermore, the brush 70 is detachable from the roller body 10, allowing for easy cleaning as needed.

[0060] Based on the same concept, one embodiment of the present invention further provides the aforementioned roller brush assembly 100. In the rotational direction a of the roller body 10, the bristle brush 70 is positioned first, followed by the rubber brush 50. In the rotational direction a, the rubber brush 50 is positioned in front of the bristle brush 70, and the rubber brush 50 abuts the windward side 71 of the bristle brush. During the rotation of the roller body 10, the front rubber brush 50 first contacts the ground, blocking hair on the ground and preventing it from becoming entangled with the bristle brush 70. This reduces hair entanglement, prevents the roller brush assembly 100 from becoming stuck due to hair entanglement, and improves the operating efficiency of the roller brush assembly 100. Furthermore, the bristle brush 70 is detachable from the roller body 10 and can be removed as needed for easier cleaning.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0062] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
