[0072] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0073] With the development of technology, cleaning equipment has become increasingly popular, and floor cleaning work in homes and offices has been gradually replaced by cleaning equipment.

[0074] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized, illustrative, and not restrictive manner.

[0075] Figure 1 This is a schematic diagram of the structure of the dirt collection component 10 according to an embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the airflow path for the aforementioned dirt collection component 10. (Combined with...) Figure 1 as well as Figure 2 The dirt collection assembly 10 includes a drive unit 400, a roller brush 500, a fan 100, a dirt guide cover 300, and a dust box (also called a dirt collection component) 200. During the operation of the cleaning equipment, the drive unit 400 drives the roller brush 500 to run on the surface to be cleaned to collect dirt on the surface. At this time, the fan 100 is in operation to suck the dirt collected by the roller brush 500 into the dust box 200 through the dirt guide cover 300, automatically completing the cleaning work on the surface to be cleaned. It should be noted that... Figure 1 and Figure 2This illustration is merely for the reader's convenience, showing an example of the installation and possible application environment of the roller brush 500. It is understood that the roller brush 500 can be installed or applied to other dirt collection components or cleaning equipment, and can achieve the same cleaning effect.

[0076] Since the dirt on the surface to be cleaned may be tangled with hair or other debris, when the roller brush 500 performs its cleaning action, this tangled debris can easily become entangled on the roller brush 500 as it rotates. Excessive tangled debris on the roller brush 500 can cause it to rub against the surface to be cleaned, producing abnormal noises, or even deform (for example, if the roller brush 500 is made of rubber), thus affecting the cleaning effect.

[0077] Based on the aforementioned technical problems, the roller brush 500 provided in this application includes at least one blade that can move relative to the brush body under the drive of a transmission component, so as to cut off the entangled material wrapped around the surface of the roller brush 500, thereby preventing the roller brush 500 from making abnormal noises, deforming, or affecting the operation of the roller brush 500 itself or even the cleaning equipment on which the roller brush 500 is installed due to being entangled by the entangled material, and improving the cleaning effect of the cleaning equipment. The following will combine... Figures 3 to 62 The roller brush 500 described in several embodiments of this application will be described in detail.

[0078] Figure 3 This is a schematic diagram of the structure of a roller brush 500a according to an embodiment of this application. The roller brush 500a is one type of roller brush 500. For example... Figure 3 As shown, the roller brush 500a includes at least two blades 505 that reciprocate relative to each other to cut off the entangled material wrapped around the roller brush 500a, thereby improving the operating efficiency of the roller brush 500a and the cleaning effect of the cleaning equipment with the roller brush 500a installed.

[0079] like Figure 3 As shown, in addition to the blade body 505, the roller brush 500a also includes a brush body 501. The brush body 501 is a hollow columnar structure that forms the main body of the entire roller brush 500a and serves as the mounting base for the other components of the roller brush 500a. One end of the brush body 501 is configured to connect to the drive device 400 of the cleaning equipment so that it rolls on the surface to be cleaned under the drive of the drive device 400, thereby gathering the dirt adhering to the surface to be cleaned.

[0080] Specifically, such as Figure 3 As shown, a connecting portion 5011 is provided at one axial end of the brush body 501. The brush body 501 is connected to the drive unit 400 of the cleaning equipment through the connecting portion 5011, so that the brush body 501 can roll on the surface to be cleaned under the drive of the drive unit 400 to gather the dirt adhering to the surface to be cleaned. Furthermore, as... Figure 3As shown, a support base 502 is provided at the other axial end of the brush body 501. The other axial end of the brush body 501 is rotatably connected to the support base 502 through components such as bearings. The support base 502 is fixedly placed on the cleaning equipment. When the cleaning equipment is running, the brush body 501 rotates relative to the support base 502.

[0081] In addition, such as Figure 3 As shown, the roller brush 500a also includes a cleaning component 503, which is integrally formed or embedded in the periphery of the brush body 501. The cleaning component 503 has a certain degree of elasticity so that it can contact the surface to be cleaned during the rotation of the roller brush 500a, and roll to sweep and gather the dirt on the surface to be cleaned.

[0082] like Figure 3 As shown, the cleaning component 503 includes at least one cleaning strip 5031. When the number of cleaning strips 5031 is greater than one, these cleaning strips 5031 can be spaced apart on the circumferential surface of the brush body 501. The spaced-apart arrangement means that there is a certain interval between adjacent cleaning strips. Furthermore, at least one cleaning strip 5031 can extend along the axial direction of the brush body 501 between its axial ends; at least one cleaning strip 5031 can also extend along a direction that forms an angle with the axial direction of the brush body 501 between its axial ends; or at least one cleaning strip 5031 can also extend along an arc, spiral, or other regular or irregular curve between its axial ends. Moreover, any two of the at least one cleaning strip 5031 can have the same or different shapes. This application does not limit the number, extension direction, or whether the two ends of the cleaning strips 5031 abut against the axial ends of the brush body 501, so that during the rolling of the roller brush 500a on the surface to be cleaned, linear entangled objects such as hair can move along at least one cleaning strip 5031 to or be held at the blade body 505 as the roller brush 500a rotates. However, to clarify the possible structure and function of the cleaning strips 5031 for the reader, the following will explain... Figure 4 A detailed example and description of at least one of the cleaning strips 5031 is provided.

[0083] like Figure 3 As shown, the cleaning component 503 also includes at least one row of bristles 5033 disposed on the circumferential surface of the brush body 501. The arrangement direction of each row of bristles 5033 can be consistent with the arrangement direction of the corresponding row of cleaning strips 5031, so as to improve the cleaning effect of the roller brush 500a on the carpet and other surfaces to be cleaned, while ensuring that hair and other tangled objects are not blocked by the bristles 5033 as the roller brush 500a rotates. It should be noted that the roller brush 500a provided in this application may include only at least one cleaning strip 5031 or only at least one bristle 5033, or it may include both at least one cleaning strip 5031 and at least one row of bristles 5033.

[0084] Figure 4 This is a schematic diagram of a cleaning strip 5032 according to an embodiment of this application. The cleaning strip 5032 is one of at least one cleaning strip 5031. Figure 4 As shown, the inner side of the cleaning strip 5032 is fixed, integrally formed, or embedded in one side of the brush body 501, and is also referred to as the inner edge 50321 of the cleaning strip 5032. The outer side of the cleaning strip 5032 is the edge side away from the brush body 501, and is therefore also referred to as the edge side 50322 of the cleaning strip 5032. Figure 4 In the illustrated embodiment, the cleaning strip 5032 is folded by providing folding ribs 50323 from the inner side 50321 to the outer side 50322. The length L of the folding ribs 50323 is the shortest distance from the inner edge 50321 along the surface of the cleaning strip 5032 to the outer edge 50322, so that the wrapped material can be guided to the area where the blade 505 operates. Figure 4 As shown, in this embodiment, a folding rib 50323 is provided in the middle of the cleaning strip 5032. However, it is understood that folding ribs 50323 can also be provided at other positions of the cleaning strip 5032 to guide the wrapped material to the working area of ​​the blade body 505.

[0085] In addition, such as Figure 4 As shown, the inner edge 50321 of the cleaning strip 5032 is V-shaped or U-shaped, so that the outer edge 50322 of the cleaning strip 5032 is correspondingly V-shaped or U-shaped, thus achieving a better effect of gathering dirt. That is, the cleaning strip 5032 consists of two cleaning sections with opposite directions of rotation. As the roller brush 500a rolls on the ground, tangled objects such as hair will move along the spiral cleaning strip 5031 and gather between the two cleaning sections as the roller brush 500a rotates. Accordingly, the working area of ​​the blade body 505 can be set between these two cleaning sections. In a specific implementation, the ends of the two cleaning sections that are close to each other can be connected together by a folding rib 50323 to guide the tangled objects in contact with the two cleaning sections to the working area of ​​the blade body 505. Furthermore, those skilled in the art will understand that the inner edge of the cleaning strip 5032 can also be straight, spiral, or other curved, and correspondingly, the outer edge of the cleaning strip 5032 can also be straight, spiral, or other curved.

[0086] In another embodiment, Figure 4 The two cleaning sections shown may not be connected, so that hair and other tangled objects can be gathered from both ends to the gap between the two cleaning sections, which is the working area of ​​the blade 505, by following the flow design of the two cleaning sections.

[0087] In another embodiment, the cleaning strip 5032 may be at least partially straight, oblique, or / and arc-shaped. Each cleaning strip 5031 may also include the two cleaning segments 5032 mentioned above. The shapes of the two cleaning segments 5032 may be the same or different. During the rolling of the roller brush 500a on the ground, hair and other tangled objects can also move along the setting direction of the cleaning strip 5031 as the roller brush 500a rotates.

[0088] In another embodiment, Figure 4 The cleaning strip 5032 shown can also be designed as a streamlined whole, without needing to have Figure 4 The folding rib 50323 shown may have segmented connecting ribs, but these connecting ribs do not need to fold the cleaning section into a spiral or curved shape. This allows tangled materials such as hair to directly converge along the streamlined cleaning strip 5032 to the working area of ​​the blade body 505. The tangled materials such as hair can converge from both ends of the cleaning strip 5032 towards the middle, or from any segment of the cleaning strip 5032 towards another segment, to reach the working area of ​​the blade body 505.

[0089] In another embodiment, Figure 4 The cleaning strip 5032 shown can also be a single, integrated design, without the need for... Figure 4 The folding rib 50323 shown may have segmented connecting ribs, but these connecting ribs do not need to fold the cleaning section into a streamlined shape such as a spiral or curve. They can simply allow hair and other tangled objects to be placed in the working area of ​​the blade 505. At this time, because the hair and other tangled objects are flexible, the hair and other tangled objects supported on the cleaning strip 5032 will fall into the working area of ​​the blade 505 and be cut by the blade 505.

[0090] Figure 5 for Figure 3 The schematic diagram of the roller brush 500a shown is combined with... Figure 5 A cutting groove 504 is formed on the periphery of the brush body 501, penetrating both the inner and outer peripheries of the brush body 501. The cutting groove 504 is connected to the interior of the brush body 501, and is passed through by the cutting edge of the blade 505, allowing the blade 505 to cut the material wrapped around the brush body 501. Protective teeth 506 are provided outside the cutting groove 504 to prevent the user or the surface to be cleaned from directly contacting the cutting edge. The cutting edge of the blade 505 is at least partially positioned above the cutting groove 504 but below the protective teeth 506. The following will combine... Figure 6 The specific shape of the cutting groove 504 and how the cutting groove 504 houses the cutter body 505 are described in detail.

[0091] Figure 6 for Figure 3The radial cross-sectional view of the roller brush 500a is shown. Figure 6 As shown, in one embodiment, the cutting grooves 504 are two, and are arranged to pass through each other along the hollow brush body 501. The blade body 505 includes a first blade body 5051 ( Figure 7 (as shown) and the second cutter body 5052 ( Figure 8 As shown in the diagram, the first blade 501 has cutting edges on both sides. These cutting edges are positioned on both sides of the brush body 501 and protrude from corresponding cutting grooves 504. Two second blades 5052 are provided, with their cutting edges positioned on both sides of the brush body 501 and protruding from corresponding cutting grooves 504. The cutting edge of each second blade 5052 is positioned opposite to the cutting edge of the first blade 5051. Through the relative movement of the cutting edges of the first blade 5051 and the second blades 5052, which are at least partially higher than the cutting grooves 504, the material wrapped around the brush body 501 is cut, improving cutting efficiency.

[0092] In another embodiment, a cutting groove 504 is provided on the periphery of the brush body 501. Correspondingly, the cutting edge of the first blade 5051 is provided as one, and the second blade 5052 is also provided as one piece, so as to cut the wrapped material wrapped on the brush body 501 by the cutting edge of the first blade 5051 and the cutting edge of the second blade 5052 cooperating with each other.

[0093] Combination Figure 5 as well as Figure 6 In one embodiment, the cutting groove 504 is generally elongated and extends along the axial direction of the brush body 501 between its two axial ends. The cutting groove 504 has suitable dimensions to ensure that the blade 505 has sufficient cutting range (i.e., working area) within the cutting groove 504, guaranteeing the cutting effect on the material wrapped around the brush body 501. Figure 5 as well as Figure 6 The cutting groove 504 can be provided between two adjacent ones in at least one cleaning strip 5031, wherein the adjacent ones can be axially adjacent or circumferentially adjacent.

[0094] Combination Figure 5 as well as Figure 6 In one embodiment, the protective tooth 506 comprises two individual structures, each integrally formed on the periphery of the brush body 501 and disposed opposite to each other on either side of the opening of the cutting groove 504 formed on the periphery of the brush body 501. In another embodiment, the protective tooth 506 may also be a single integral structure, integrally formed on the outside of the opening of the cutting groove 504 formed on the periphery of the brush body 501. Furthermore, it should be noted that the brush body 501 of this application may also include at least two detachably connected individual structures to facilitate the assembly, maintenance, and replacement of the brush body 501 and its internal components.

[0095] The protective tooth 506 protrudes from the opening of the cutting groove 504. The blade 505 is disposed within the opening of the cutting groove 504, and its cutting edge is at least partially higher than the opening of the cutting groove 504, but lower than the protective tooth 506 (i.e., located within the protective tooth 506). This allows the protective tooth 506 to cover the portion of the blade 505 protruding from the cutting groove 504, preventing the user from being injured by the exposed blade 505 or its cutting edge, preventing the flexible surface to be cleaned from being injured by the exposed blade 505 or its cutting edge, or preventing the blade 505 or its cutting edge from contacting the rigid surface to be cleaned or dirt, thus preventing excessive wear. The protective tooth 506 has multiple teeth with inter-tooth portions that communicate with the cutting groove 504. Hair and other entangled objects can fall into the cutting groove 504 through these inter-tooth portions and be cut by the blade 505, thereby being sucked in. Figure 2 The dust box (also known as the dirt collection component) 200 shown effectively improves the operating efficiency of the roller brush 500a, extends its service life, and enhances the cleaning efficiency of cleaning equipment equipped with the roller brush 500a. Simultaneously, the protective teeth 506 pre-untangle tangled materials, making them easier to guide or fall into the working area of ​​the blade body 505. Furthermore, because the protective teeth 506 protrude from the brush body 501, although they typically do not exceed [the specified height]... Figure 3 The height of the cleaning component 503 is shown, but in some cases, the protective teeth 506 can pre-contact the surface to be cleaned to prevent the blade 505 from directly contacting the surface to be cleaned, thus avoiding damage to the surface to be cleaned or the blade 505, thereby protecting the surface to be cleaned or the cutting 505, improving the user experience and / or the service life of the blade 505.

[0096] Furthermore, in one embodiment, since the cleaning device's fan 100 sucks away the cut hair and other tangled material when it is running, there may be a small gap between the first blade 5051 and the second blade 5052 to maintain the smoothness of the relative movement between the first blade 5051 and the second blade 5052.

[0097] However, in another embodiment, the cutting edge of the first blade 5051 is configured to fit against the second blade 5052 or its cutting edge, to a certain extent preventing hair and other entangled objects from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus affecting the operation of the brush body 501. Under long-term use of the cleaning equipment, because the cutting edge of the first blade 5051 and the second blade 5052 reciprocate relative to each other and are arranged in close contact, the cutting edge of the first blade 5051 and / or the second blade 5052 will experience some wear, potentially creating a gap between them or widening an existing gap. Based on this, combined with... Figure 6The roller brush 500a of this application also includes an elastic element 507. The elastic element 507 can compensate for the wear of the cutting edge of the first blade 5051 and / or the second blade 5052, so that the cutting edge of the first blade 5051 and the second blade 5052 remain in contact, thereby preventing cut or uncut hair and other tangled objects from entering the brush body 501 through the gap between them and affecting the operation of the brush body 501. Specifically, as Figure 6 As shown, in one embodiment of this application, the aforementioned elastic element 507 is respectively provided between the cutting edge of the first blade 5051 and the groove wall of the cutting groove 504, and between the second blade 5052 and the groove wall of the cutting groove 504, to compensate for wear caused by the relative movement of the first blade 5051 and the second blade 5052, so that the two remain in contact. In another embodiment, the aforementioned elastic element 507 may also be provided only between the cutting edge of the first blade 5051 and the groove wall of the cutting groove 504, or only between the second blade 5052 and the groove wall of the cutting groove 504, to compensate for wear of at least one of the first blade 5051 and the second blade 5052, so that the two remain in contact.

[0098] Figure 9 This is a schematic diagram showing the first blade body 5051 arranged side by side inside the brush body 501, in conjunction with... Figures 7-9 The second blade 5052 is an elongated structure, its length slightly less than the length of the cutting groove 504, so that the second blade 5052 can oscillate back and forth within the cutting groove 504. Multiple first blades 5051 are spaced apart along the axial direction of the brush body 501, with gaps between them, allowing at least one first blade to oscillate independently. The overall length of the cutting edges of the multiple first blades 5051 is approximately the same as the overall length of the second blade 5052, ensuring effective cutting of the wrapped material on the surface of the roller brush 500a. Furthermore, two clearance recesses 5053 are provided on the periphery of the first blade 5051, positioned between the two cutting edges of the first blade 5051, to reduce the space occupied by the first blade 5051 within the brush body 501, increase the oscillation amplitude of the first blade 5051, and thus improve the shearing effect on the wrapped material.

[0099] Combination Figure 9In one embodiment, at least two first blades are arranged side-by-side along the axial direction of the brush body 501. These first blades have identical structures, and the first blade 5051 is any one of them. Therefore, an elastic member 507 that can abut against the cutting edge of all or each of the first blades is required. Specifically, the elastic member 507 can be a single-piece structure, individually provided to correspond to each first blade, and each is assembled in a mounting groove 5012 on the side wall of the brush body 501; the elastic member 507 can also be an integral structure, integrally formed to correspond to all the first blades, and integrally assembled in the mounting groove 5012 on the side wall of the brush body 501. The elastic element 507 disposed between the second blade body 5052 and the groove wall of the cutting groove 504 can be a split or integral structure, and is assembled in the mounting groove 5012 on the side wall of the brush body 501. The split refers to cutting the elastic element, which is preferably an integral piece, into multiple pieces. However, in this case, the combination of these pieces can achieve the effect of being assembled as a whole, or similarly but inferiorly, in the mounting groove 5012 on the side wall of the brush body 501.

[0100] Combination Figure 9 At least two first cutter bodies are arranged side by side along the axial direction of the brush body 501. These first cutter bodies have the same structure. Therefore, taking any one of the first cutter bodies 5051 as an example, combined with... Figure 10 The working process of each first cutter body is explained in detail.

[0101] Figure 10 for Figure 9 The diagram shows the assembly of the transmission component 508. Figure 9 as well as Figure 10 As shown, the roller brush 500a also includes a transmission assembly 508, which is placed inside the brush body 501 and connected to the first blade body 5051 to drive the first blade body 5051 to reciprocate relative to the brush body 501. Specifically, in conjunction with Figure 9 as well as Figure 10 A support shaft 5054 is provided in the middle of the first blade body 5051. In one embodiment, the support shaft 5054 can be fixedly placed inside the brush body 501, and the first blade body 5051 is loosely sleeved on the support shaft 5054. Driven by the transmission assembly 508, the first blade body 5051 reciprocates around the support shaft 5054. In another embodiment, both ends of the support shaft 5054 can also be rotatably connected inside the brush body 501. The first blade body 5051 can be fixedly connected to the support shaft 5054 by means of key connection or other means. Driven by the transmission assembly 508, the first blade body 5051 and the support shaft 5054 reciprocate synchronously.

[0102] Specifically, multiple first blades 5051 are directly or indirectly connected to the transmission assembly 508, so as to drive the multiple first blades 5051 to reciprocate. Among them, the first blades adjacent to the support base 502 are directly connected to the transmission assembly 508 to reduce the space occupied by the transmission assembly 508 in the brush body 501, while the first blades at other positions are indirectly connected to the transmission assembly 508.

[0103] Combination Figure 9 as well as Figure 10 The transmission assembly 508 includes a drive member 5081 and a swing arm 5082. The drive member 5081 is provided with a rotatable drive part, one end of the swing arm 5082 is connected to the drive part, and the other end of the swing arm 5082 is eccentrically connected to the first cutter body 5051. When the drive member 5081 rotates, the drive part of the drive member 5081 drives the first cutter body 5051 to reciprocate around its support shaft 5054 via the swing arm 5082.

[0104] Combination Figure 9 as well as Figure 10 The drive component 5081 includes a worm gear mechanism. The worm of the worm gear mechanism is connected to a support seat 502 at the other axial end of the brush body 501. When the roller brush 500a rolls on the ground, the worm of the worm gear mechanism rotates relative to the brush body 501, thereby driving the worm wheel of the worm gear mechanism to rotate. The worm wheel of the worm gear mechanism is configured as the drive part of the drive component 5081. One end of the swing arm 5082 is fitted onto the rotating shaft of the worm gear, and the other end of the swing arm 5082 is rotatably connected to the connecting shaft 5055 of the first cutter body 5051. The connecting shaft 5055 is eccentrically arranged with the support shaft 5054 of the first cutter body 5051, so that the rotation of the worm gear drives the first cutter body 5051 to rotate around its support shaft 5054. Because the drive component 5081 in the roller brush 500a adopts a worm gear mechanism for power transmission, it has the characteristics of smooth operation, low impact, vibration and noise, and can adapt to the assembly in the narrow space inside the brush body.

[0105] Figure 11 This is a schematic diagram of the assembly of multiple first tool bodies 8051 with the transmission component 509. (Combined) Figure 11To drive multiple first blades 5051 to reciprocate synchronously, the roller brush 500a of this application may further include a transmission member 509. Additionally, each first blade 5051 is eccentrically mounted with a transmission shaft 5056. The transmission member 509 is rotatably connected to the multiple transmission shafts 5056, and can reciprocate within the brush body 501. When the transmission assembly 508 drives a particular first blade 5051 to reciprocate around its support shaft 5054, the transmission member 509 drives multiple first blades 5051 to reciprocate synchronously around their support shaft 5054. In a specific implementation, the transmission component 509 can be a plate-shaped structure, which is arranged approximately along the axial direction of the brush body 501. The transmission component 509 is connected to the side of the multiple first blades 5051 facing away from the second blades 5052. The connecting shaft 5055 on the first blade 5051 connected to the swing arm 5082 connected to the transmission assembly 508 can be configured as the transmission shaft 5056 of the first blade 5051 to save parts and adapt to the internal space of the brush body 501.

[0106] Combination Figure 11 A wear-resistant component 510 is provided between the transmission component 509 and each first cutter body 5051. The wear-resistant component 510 can be solidly connected to the corresponding first cutter body 5051. The wear-resistant component 510 can be elastic to compensate for the wear of at least one of the first cutter body 5051 and the second cutter body 5052 during use. In a specific implementation, the wear-resistant component 510 is intermittently connected to the support shaft and the transmission shaft 5056 of the corresponding first cutter body 5051, so that the wear-resistant component 510 and the first cutter body 5051 are relatively fixed by the pressing of the transmission component 509; or, the wear-resistant component 510 can be glued or screwed to the corresponding first cutter body 5051, which is not limited here.

[0107] Figure 12 This is a schematic diagram of the assembly of the connecting rod assembly 511 with the first cutter body 5051 and the second cutter body 5052. (Combined with...) Figure 12 According to one embodiment of this application, the brush body 501 further includes a connecting rod assembly 511, which is disposed inside the brush body 501 and is respectively connected to the first blade 5051 and the second blade 5052 to drive the second blade 5052 to swing back and forth relative to the first blade 5051.

[0108] Figure 13 for Figure 12 The enlarged diagram at point A, combined with Figure 12 as well as Figure 13The linkage assembly 511 includes a first linkage 5111 and a second linkage 5112. One end of the first linkage 5111 is eccentrically and rotatably connected to the first blade body 5051 via a first pivot 5115. One end of the second linkage 5112 is rotatably connected to the other end of the first linkage 5111 via a second pivot 5116. The middle part of the second linkage 5112 is connected to the second blade body 5052 via a third pivot 5117. The other end of the second linkage 5112 is rotatably connected to the brush body 501 via a fourth pivot 5118. The second pivot 5116, the third pivot 5117, and the fourth pivot 5118 are not located on a straight line. When the first cutter body 5051 is driven to swing back and forth, the first cutter body 5051 drives the second connecting rod 5112 to rotate around the third rotating shaft 5117 via the first connecting rod 5111. Since the middle part of the second connecting rod 5112 is connected to the second cutter body 5052, the second connecting rod 5112 can drive the second cutter body 5052 to swing back and forth synchronously while rotating around the third rotating shaft 5117, so that the second cutter body 5052 and the multiple first cutters 5051 form a swinging motion of mutual shearing to shear the wrapped material on the roller brush 500a.

[0109] Combination Figure 12 as well as Figure 13 The first end of the first connecting rod 5111 is connected to the drive shaft 5056 of the first cutter body 5051 connected to the transmission member 509. The drive shaft 5056 of the first cutter body 5051 can be configured as a first rotating shaft 5115. That is, the first rotating shaft 5115 of the connecting rod assembly 511 and the drive shaft 5056 on the first cutter body 5051 connected to the connecting rod assembly 511 can be the same shaft to save parts and adapt to the internal space of the brush body 501.

[0110] Combination Figure 12 as well as Figure 13 In one embodiment, the second link 5112 can be approximately V-shaped, preferably with an acute angle, so that the second pivot 5116, the third pivot 5117, and the fourth pivot 5118 on the second link 5112 are not on a straight line and adapt to the internal space of the brush body 501. In another embodiment, the second link 5112 can also be arc-shaped, which is not limited herein.

[0111] Combination Figure 12 as well as Figure 13 According to one embodiment of this application, the linkage assembly 511 may further include a third linkage 5113, the two ends of which are rotatably connected to the second rotating shaft 5116 and the third rotating shaft 5117 respectively, so as to restrict the movement of the first linkage 5111 and the second linkage 5112 toward the third rotating shaft 5117, so as to restrict the movement direction of the linkage assembly 511 and adapt to the internal space of the brush body 501.

[0112] Combination Figure 12 as well as Figure 13 Since two second cutter bodies 5052 can be arranged opposite each other on both sides of the fourth rotating shaft 5118, the linkage assembly 511 of this application further includes a fourth link 5114. One end of the fourth link 5114 is fixedly connected to the other end of the second link 5112, and the other end of the fourth link 5114 is rotatably connected to the second cutter body 5052 through the fifth rotating shaft. During the reciprocating swing of the first cutter body 5051, the linkage assembly 511 is driven to move around the fourth rotating shaft 5118. Since one end of the fourth link 5114 is fixedly connected to the other end of the second link 5112, the reciprocating swing of the first cutter body 5051 also drives the fourth link 5114 to rotate around the fourth rotating shaft 5118. Since the other end of the fourth link 5114 is rotatably connected to the second cutter body 5052 through the fifth rotating shaft, the second cutter body 5052 is then driven to reciprocate. Specifically, a connecting rod assembly 511 drives two second blades 5052 to reciprocate. The reciprocating motion of the two second blades 5052 cooperates with the two shearing sections of multiple first blades 5051 to improve the shearing effect and efficiency on the surface of the brush body 501. At the same time, the connecting rod assembly 511 supports and connects the two second blades 5052, allowing them to be positioned opposite each other within the brush body 501 without the need for other components to connect the second blades 5052, thus simplifying the structure.

[0113] Combination Figure 12 as well as Figure 13 Each of the two second cutter bodies 5052 has a connecting protrusion 5057 on one side opposite to the other. The fourth connecting rod 5114 and the second connecting rod 5112 can be integrally formed to form a rod structure. The two ends of the rod structure are rotatably connected to the connecting protrusions 5057 of the two second cutter bodies 5052 through corresponding rotating shafts.

[0114] Combination Figure 12 The linkage assembly 511 of this application can be provided in two or more at intervals along the axial direction of the brush body 501. The first ends of the first linkage 5111 of the two linkage assemblies 511 are respectively connected to the two first blades 5051 so as to effectively support and connect the two second blades 5052, so that the two second blades 5052 can swing smoothly.

[0115] In summary, the roller brush 500a provided in this application, through the reciprocating oscillation of multiple first cutter bodies 5051 in conjunction with the reciprocating oscillation of a second cutter body 5052, can cut away any entanglement that may be wrapped around the roller brush 500a, reduce the entanglement on the surface of the roller brush 500a, improve the cleanliness of the roller brush 500a surface, thereby reducing the resistance of the roller brush 500a's operation and avoiding affecting the operation of the roller brush 500a. At the same time, it also improves the cleaning efficiency of the roller brush 500a, thereby improving the cleaning effect of the cleaning equipment and has good practicality.

[0116] Figure 14 This is a schematic diagram of another type of roller brush 500b according to this application. (Combined with...) Figure 14 This application provides a roller brush 500b, which includes at least one cutting component. Each cutting component includes at least one rotating blade that can cut away debris that may be entangled on the roller brush, thereby reducing the debris on the roller brush surface, improving the cleanliness of the roller brush surface, and avoiding affecting the operation of the roller brush, thus improving the cleaning effect of the cleaning equipment. The following is an example... Figure 14 - Appendix Figure 29 Further details regarding the 500b roller brush are described below.

[0117] Figure 14 The roller brush 500b shown is a type of roller brush 500, similar to roller brush 500a. The roller brush 500b also includes a brush body 501, a cleaning component 503, and protective teeth 506. Unless otherwise specified, the structure and function of these components in the roller brush 500b are roughly the same as those in the roller brush 500a. Therefore, the corresponding description of the roller brush 500a can be referred to, and will not be repeated here.

[0118] Figure 15 for Figure 14 A schematic diagram of the radial section of brush body 501. (Combined with...) Figure 14 as well as Figure 15 The brush body 501 has a cutting groove 504 on its periphery, which penetrates the inner and outer periphery of the brush body 501 and communicates with the interior of the brush body 501. At least part of the cutting edge of the blade 505 protrudes from the cutting groove 504 to cut the linear winding material wrapped around the brush body 501.

[0119] Combination Figure 14 as well as Figure 15In one embodiment, two cutting grooves 504 are formed on the periphery of the brush body 501, and the two cutting grooves 504 are mutually connected. At least a portion of the cutting edge of the blade body 505 protrudes from the two cutting grooves 504 to simultaneously cut the material wrapped around the brush body 501, thereby improving cutting efficiency. In another embodiment, only one cutting groove 504 may be formed on the periphery of the brush body 501, and the cutting edge of the blade body 505 protruding from the cutting groove 504 can also achieve the purpose of cutting the material wrapped around the brush body 501.

[0120] Combination Figure 14 as well as Figure 15 The cutting groove 504 can be roughly elongated to have a suitable size so that the blade 505 has a sufficient cutting range within the cutting groove 504, ensuring the cutting effect on the wrapped material on the brush body 501.

[0121] Combination Figure 14 as well as Figure 15 In one embodiment, the cutting groove 504 can be disposed between two adjacent cleaning strips 5031. Hair and other tangled material, supported on the cleaning strips 5031, will fall into the cutting groove 504 due to the flexibility of the tangled material, and be cut by the blade 505 within the cutting groove 504. Figure 14 The cutting groove 504 is located in the area between the middle of two adjacent cleaning strips 5031. When at least part of the cleaning strip 5031 is spiral, hair and other tangled objects will move and gather in the area between the two cleaning sections 5032. Then, through the cutting of the blade 505 in the cutting groove 504 between the two adjacent cleaning strips 5031, the hair and other tangled objects can be cut off significantly, so as to effectively reduce the tangled objects on the surface of the roller brush and improve the cleanliness of the roller brush surface.

[0122] In another embodiment, the cutting groove 504 can be disposed in the area between two cleaning segments of the cleaning strip 5031, that is, the two cleaning segments of the cleaning strip 5031 are spaced apart, and the cutting groove 504 is disposed between the two cleaning segments of the cleaning strip 5031. When at least a portion of the cleaning strip 5031 is spiral, tangled objects such as hair will move and gather in the area between the two cleaning segments. Then, through the cutting of the blade 505 in the cutting groove 504 between the two cleaning segments 5032, the tangled objects such as hair can be cut off significantly, thereby effectively reducing the tangled objects on the surface of the roller brush and improving the cleanliness of the roller brush surface.

[0123] Combination Figure 14 as well as Figure 15There can be two cutting components, and correspondingly, there are four cutting grooves 504. Each pair of cutting grooves 504 forms a group, and the two cutting grooves 504 in each group are connected and cooperate with the same cutting component. That is, at least part of the cutting edge on the periphery of the blade body 505 of a cutting component protrudes from two cutting grooves 504 to form two shearing parts, so as to improve the cutting effect on tangled objects such as hair.

[0124] Figure 16 for Figure 14 Internal structure diagram. Figure 17 for Figure 16 A top-down view diagram. Combined with... Figure 16 as well as Figure 17 The cutting assembly includes a first blade 5051, which is rotatably configured. At least a portion of the cutting edge on the periphery of the first blade 5051 protrudes from the cutting groove 504. By rotating the first blade 5051, the entanglement that may be wrapped around the roller brush is cut off, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, avoiding affecting the operation of the roller brush, and improving the cleaning effect of the cleaning equipment.

[0125] Combination Figure 16 as well as Figure 17 As described above, there are two cutting components arranged opposite to each other, and correspondingly, there are also two first blades 5051 arranged opposite to each other. The two opposite and rotatable first blades 5051 can simultaneously cut the entangled material that may be wrapped around the roller brush, thereby improving the cutting effect on the entangled material.

[0126] Combination Figure 16 as well as Figure 17 The roller brush also includes a transmission assembly 508, which is housed within the brush body 501 and connected to the first blades 5051 of the two cutting assemblies, respectively, to drive the first blades 5051 of the two cutting assemblies to rotate within the brush body 501, thereby cutting any material that may be entangled on the roller brush. Now, by way of the attached... Figure 17 - Appendix Figure 21 Further details of the transmission assembly 508 are described below.

[0127] Figure 18 for Figure 17 A schematic diagram of the AA cross-section. Combined with... Figure 17 as well as Figure 18In one embodiment, the transmission assembly 508 of this application includes a driving member 5081, a main gear 5083, a driving shaft 5084, and two driven gears 5085. The driving member 5081 is provided with a rotatable driving section. The main gear 5083 is connected to the driving section of the driving member 5081. The driving shaft 5084 is rotatably disposed within the brush body 501. Two first blades 5051 are connected to the driving shaft 5084. The two driven gears 5085 are mounted on the driving shaft 5084 and respectively engage with the conical surfaces of the main gear 5083. When the driving section of the driving member 5081 rotates, the main gear 5083 and the driving section of the driving member 5081 rotate synchronously to drive the two driven gears 5085, the driving shaft 5084, and the two first blades 5051 on the driving shaft 5084 to rotate synchronously, thereby shearing any material that may be wrapped around the roller brush.

[0128] Combination Figure 17 as well as Figure 18 The driving part of the driving member 5081 can be arranged along the axial direction of the brush body 501, and the driving shaft 5084 is arranged along the radial direction of the brush body 501 or parallel to the radial direction of the brush body 501, so that the driving part of the driving member 5081 and the driving shaft 5084 are arranged perpendicularly. There is a certain gap between the driving shaft 5084 and the driving part of the driving member 5081 to provide space for the arrangement of the main gear 5083 and the two driven gears 5085.

[0129] Combination Figure 17 as well as Figure 18 A fixing member 512 is fixedly installed inside the brush body 501. The middle part of the drive shaft 5084 is rotatably connected to the fixing member 512. The two ends of the drive shaft 5084 protrude from the two ends of the fixing member 512, respectively. Two first blades 5051 and two driven gears 5085 are respectively connected to the two ends of the drive shaft 5084. When the drive part of the drive member 5081 rotates, the main gear 5083 drives the driven gears 5085 to drive the drive shaft 5084 to rotate inside the fixing member 512, thereby driving the two first blades 5051 connected to the drive shaft 5084 to rotate.

[0130] Figure 19 for Figure 18 The assembly diagram of the fixing component 512 and the drive shaft 5084 is shown. (Referring to...) Figure 18 as well as Figure 19In one embodiment, the fixing member 512 can be a sleeve structure, with a positioning protrusion 5121 extending outward on its periphery. This positioning protrusion 5121 is inserted into the brush body 501 to fix the fixing member 512 within the brush body 501. Specifically, two positioning protrusions 5121 can be provided, and both protrusions 5121 can be integrally formed on the periphery of the fixing member 512. In another embodiment, the fixing member 512 can also be integrally formed or connected to the brush body 501 by screws or other components.

[0131] Figure 20 for Figure 19 A cross-sectional schematic diagram, combined with Figure 19 as well as Figure 20 The drive shaft 5084 includes a first shaft body 50841 and a second shaft body 50842. One end of the first shaft body 50841 and the second shaft body 50842 are connected to the fixing member 512, and the other end protrudes from the fixing member 512. Two first blade bodies 5051 are respectively connected to the periphery of the other end of the first shaft body 50841 and the second shaft body 50842.

[0132] Combination Figure 20 In one embodiment, one end of the first shaft 50841 and the second shaft 50842 are abutted against and grounded in the fixing member 512, and the other ends of the first shaft 50841 and the second shaft 50842 respectively abut against the inner side wall of the brush body 501. The two driven gears 5085 can be keyed and assembled on the other end of the first shaft 50841 or the second shaft 50842, so that when the driven gear 5085 is driven to rotate by the main gear 5083, The first shaft 50841 and the second shaft 50842 rotate synchronously. Two first cutting bodies 5051 can also be connected to the other ends of the first shaft 50841 and the second shaft 50842 via a key connection, and are positioned on opposite sides of the two driven gears 5085. This allows the first shaft 50841 and the second shaft 50842 to drive their respective first cutting bodies 5051 to rotate synchronously when the first shaft 50841 and the second shaft 50842 rotate. In another embodiment, the first shaft 50841 and the second shaft 50842 can also be integrally formed.

[0133] Combination Figure 20 A first support member 5086 is provided at one end opposite to the first shaft 50841 and the second shaft 50842 to support the rotation of the first shaft 50841 and the second shaft 50842 within the brush body 501. The first support member 5086 can be a bearing or a copper sleeve to ensure that the first shaft 50841 and the second shaft 50842 can rotate smoothly within the brush body 501.

[0134] Figure 21This is a schematic diagram showing the assembly of the cutting component within the brush body 501. (Combined with...) Figure 21 At least one cutting component further includes a second blade 5052, which is fixedly disposed on the brush body 501. At least a portion of the cutting edge on the periphery of the second blade 5052 protrudes from the cutting groove 504. The second blade 5052 and the first blade 5051 are disposed opposite to each other. Since the first blade 5051 is rotatably disposed within the brush body 501 and the second blade 5052 is fixedly disposed within the brush body 501, the first blade 5051 is rotatably disposed relative to the second blade 5052. By fixing the entangled material such as hair with the fixed second blade 5052, and by cutting the fixed entangled material such as hair with the second blade 5052 that rotates relative to the first blade 5051, the cutting effect on the entangled material such as hair is improved. At least one cutting component includes a second blade 5052, meaning that each cutting component may include a second blade 5052, and the first blades 5051 of the two cutting components rotate relative to the second blade 5052; or, only one cutting component has a second blade 5052, and the first blade 5051 of one cutting component rotates relative to the second blade 5052, while the other cutting component has only one rotating first blade 5051.

[0135] Combination Figure 21 In one embodiment, the first blade 5051 is disposed between the second blade 5052 and the driven gear 5085 to make reasonable use of the internal space of the brush body 501. In another embodiment, the second blade 5052 is disposed between the first blade 5051 and the driven gear 5085, and this application does not limit this.

[0136] Combination Figure 21 In one embodiment, the first blade 5051 and the second blade 5052 are fitted together to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding interference with the operation of the internal components of the brush body 501. In another embodiment, since the cleaning device's fan will suck away the cut hair during operation, a small gap may also exist between the first blade 5051 and the second blade 5052.

[0137] Figure 22 for Figure 21 A schematic diagram of the structure of the first cutter body 5051 in the process. Figure 23 for Figure 21 A schematic diagram of the structure of the second cutter body 5052. (Combined with...) Figure 22 as well as Figure 23The first cutter body 5051 and / or the second cutter body 5052 are provided with a plurality of heat dissipation holes 5059. The heat dissipation holes 5059 can be circular or square or other shapes. On the one hand, they can dissipate heat when the first cutter body 5051 rotates relative to the second cutter body 5052. On the other hand, they can reduce the contact area between the two, reduce friction, make the first cutter body 5051 rotate smoothly relative to the second cutter body 5052, and improve the service life of both.

[0138] Combination Figures 21-23 The brush body 501 has a receiving cavity 5013, the cutting groove 504 communicates with the receiving cavity 5013, the second blade body 5052 is fixedly disposed in the receiving cavity 5013, the first blade body 5051 is rotatably disposed in the receiving cavity 5013, and an elastic member 507 is disposed between at least one of the outer sides of the first blade body 5051 and the second blade body 5052 and the receiving cavity 5013. Under long-term use of the cleaning equipment, the first blade 5051 rotates relative to the second blade 5052, and the two are arranged in close contact. The first blade 5051 and / or the second blade 5052 will experience certain wear, which may cause gaps between them. Based on this, the elastic element 507 can compensate for the wear of the first blade 5051 and / or the second blade 5052, so that the first blade 5051 and the second blade 5052 remain in close contact, so as to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

[0139] Combination Figures 21-23In one embodiment, the receiving cavity 5013 includes a first receiving cavity 50131, and the second blade 5052 is matchedly assembled in the first receiving cavity 50131. The side wall of the first receiving cavity 50131 is provided with a limiting recess 50133, and there may be two limiting recesses 50133 arranged opposite to each other. The circumferential side of the second blade 5052 is provided with a first limiting protrusion 5058, and the first limiting protrusion 5058 is inserted into the corresponding limiting recess 50133 so that the second blade 5052 can be relatively fixedly assembled in the first receiving cavity 50131. The receiving cavity 5013 also includes a second receiving cavity 50132, which communicates with the first receiving cavity 50131. The thickness of the second receiving cavity 50132 is slightly greater than the thickness of the first blade 5051. The first blade 5051 is rotatably mounted in the first receiving cavity 50131. The aforementioned elastic element 507 is provided between the side of the first blade 5051 facing away from the second blade 5052 and the side wall of the second receiving cavity 50132. Under the condition of wear of the first blade 5051 and / or the second blade 5052, the elastic element 507 can compensate for the wear of the first blade 5051 and / or the second blade 5052, so that the first blade 5051 and the second blade 5052 remain in contact. In another embodiment, the thickness of the first receiving cavity 50131 may be slightly greater than the thickness of the second blade 5052. The second blade 5052 can move slightly within the first receiving cavity 50131. An elastic element 507 is provided between the side of the second blade 5052 facing away from the first blade 5051 and the sidewall of the first receiving cavity 50131. Alternatively, an elastic element 507 is provided between the side of the second blade 5052 facing away from the first blade 5051 and the sidewall of the first receiving cavity 50131, and between the side of the first blade 5051 facing away from the second blade 5052 and the sidewall of the second receiving cavity 50132, to compensate for the wear of the first blade 5051 and / or the second blade 5052, so that the first blade 5051 and the second blade 5052 remain in a close fit.

[0140] Figure 24 for Figure 21 A schematic diagram of the elastic element 507 in the diagram. (Combined with...) Figure 24 The elastic element 507 is roughly circular in shape. A second limiting protrusion 5071 is provided on the periphery of the elastic element 507. Two second limiting protrusions 5071 can be provided opposite each other to abut against the inner wall of the second receiving cavity 50132 so that the elastic element 507 can be fixedly installed in the brush body 501.

[0141] Figure 25 This is an assembly diagram of the first cutter body 5051 and the driven gear 5085. Figure 26 This is a structural schematic diagram of partition component 513. (Combined with...) Figure 25 as well as Figure 26A partition 513 is provided between the first cutter body 5051 and the driven gear 5085. The partition 513 can be placed at a distance in the middle of the elastic member 507. The partition 513 can be a wave-shaped gasket, which can separate the first cutter body 5051 and the driven gear 5085 in the axial direction of the drive shaft 5084 to avoid interference between them. The contact between the partition 513 and the first cutter body 5051 and the driven gear 5085 is partial contact, so as to reduce the friction area between the partition 513 and the first cutter body 5051 and the driven gear 5085, and make the first cutter body 5051 and the driven gear 5085 rotate smoothly.

[0142] In another embodiment, the first cutter body 5051 can also be directly connected to the main gear 5083. When the driving part of the driving member 5081 rotates, the main gear 5083 and the driving part of the driving member 5081 rotate synchronously to drive the first cutter body 5051 connected to the driven gear 5085 to rotate, which can also cut the wrapped material that may be wrapped on the roller brush.

[0143] Figure 27 for Figure 16 A structural schematic diagram of the drive component 5081. (Combined with...) Figure 27 The drive unit 5081 includes a power input shaft 5087, a reduction mechanism 5088, and a power output shaft 5089 connected in sequence. The power output shaft 5089 is configured as a drive unit. The power input shaft 5087 is placed inside the brush body 501 and intersects with the central axis of the drive shaft 5084. The power input shaft 5087 is connected to the power output shaft 5089 through the reduction mechanism 5088 so that the rotational speed of the power output shaft 5089 can be reduced to a suitable range, which also reduces the rotational speed of the driven gear 5085 and the first cutter body 5051, thereby reducing noise and reducing the wear of the first cutter body 5051 and the second cutter body 5052.

[0144] Combination Figure 27 One end of the power input shaft 5087 can be connected to the support seat 502 at the other end of the brush body 501. When the roller brush moves and rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501, so as to transmit power to the main gear 5083 through the reduction mechanism 5088 and the power output shaft 5089, so as to drive the driven gear 5085 and the first cutter body 5051 to rotate.

[0145] Combination Figure 27One or more second support members 514 can be provided inside the brush body 501. The power input shaft 5087 rotatably passes through the second support member 514 to support the power input shaft 5087. The second support member 514 can be a bearing or a copper sleeve to ensure that the power input shaft 5087 can rotate stably within the second support member 514. In specific implementations, the number of support members can be set according to the length of the power input shaft 5087. If the power input shaft 5087 is long, multiple second support members 514 can be provided; if the drive shaft is short, only one second support member 514 can be provided.

[0146] Because the roller brush rotates at a relatively high speed, the first blade 5051 rotating in the cutting assembly also rotates at a relatively high speed, resulting in faster wear of the blade 505. Therefore, this application provides a reduction mechanism 5088 between the power input shaft 5087 and the power output shaft 5089 to reduce the speed of the power output shaft 5089, thereby reducing the speed of the first blade 5051 accordingly. This reduces wear on the blade 505 while ensuring the shearing effect on the wound material. The details of the reduction mechanism 5088 are now further described with reference to the accompanying drawings.

[0147] According to one embodiment of this application, the reduction mechanism 5088 is a planetary gear reducer. Planetary gear reducers are characterized by small size, high load-bearing capacity, and stable operation, and can adapt to the internal space of the brush body 501, ensuring stable power output. A planetary gear reducer can have one or more transmission stages; the more stages, the larger the reduction ratio. The number of stages can be set according to the reduction requirements. The following is an example... Figure 28 - Appendix Figure 29 The structure of the planetary gear reducer is further explained.

[0148] Figure 28 This is a structural schematic diagram of the 5088 reduction mechanism. (Combined with...) Figure 28 The reduction mechanism 5088 includes a housing 50881, which is positioned between the power input shaft 5087 and the power output shaft 5089. A positioning protrusion 50882 is provided on the periphery of the housing 50881. The positioning protrusion 50882 is inserted into or abuts against the inner wall of the brush body 501, so that the housing 50881 of the reduction mechanism 5088 can be fixed relative to the brush body 501. Furthermore, teeth are provided on the inner periphery of the housing 50881 to mesh with the planetary gears of the planetary gear reducer, ensuring smooth operation of the planetary gears.

[0149] Figure 29 for Figure 28 The diagram shown below illustrates the internal structure of the speed reduction mechanism 5088. Figure 29The reduction mechanism 5088 includes a primary central gear 50883, primary planetary gears 50884, and a primary planetary carrier 50885. The primary planetary carrier 50885 is housed within a housing 50881 and is spaced axially from one end of the housing 50881. One end of the central shaft of the primary central gear 50883 passes through the axial end of the housing 50881 and is connected to the power input shaft 5087. The other end of the central shaft of the primary central gear 50883 is rotatably connected to the primary planetary carrier 50885. Multiple primary planetary gears 50884 are spaced and meshed around the periphery of the primary central gear 50883. Multiple primary planetary gears... One end of the central shaft of the planetary gear 50884 intermittently abuts against one axial end of the housing 50881. The other ends of the central shafts of the multiple planetary gears are connected to the first-stage planetary carrier 50885. The first-stage planetary carrier 50885 can be connected to the power output shaft 5089. When the power input shaft 5087 is rotated, the first-stage central gear 50883 and the power input shaft 5087 rotate synchronously to drive the multiple first-stage planetary gears 50884 to revolve around the first-stage central gear 50883. At the same time, it drives the first-stage planetary carrier 50885 to rotate around the central shaft of the first-stage central gear 50883, and then transmits the power to the power output shaft 5089 for output, thus forming a first-stage reduction.

[0150] Combination Figure 29 The reduction mechanism 5088 further includes a secondary central gear 50886, secondary planetary gears 50887, and a secondary planetary carrier 50888. The secondary planetary carrier 50888 and the primary planetary carrier 50885 are spaced apart within the housing 50881. The secondary planetary carrier 50888 abuts against the other axial end of the housing 50881 with a gap. The input end of the central shaft of the secondary central gear 50886 is fixedly connected to the middle of the primary planetary carrier 50885, and the other end of the central shaft of the secondary central gear 50886 is rotatably connected within the secondary planetary carrier 50888. Multiple secondary planetary gears 50887 are spaced apart and mesh with the circumference of the secondary central gear 50886. Multiple secondary planetary gears... One end of the central shaft of the gear 50887 intermittently abuts against the primary planetary carrier 50885, and the other end of the central shaft of the multiple secondary planetary gears 50887 is connected to the secondary planetary carrier 50888. The secondary planetary carrier 50888 is connected to the power output shaft 5089. Under the condition that the primary planetary carrier 50885 rotates around the central shaft of the central gear, it drives the secondary central gear 50886 to rotate, which in turn drives the multiple secondary planetary gears 50887 to revolve around the secondary central gear 50886. At the same time, it drives the secondary planetary carrier 50888 to rotate around the central shaft of the secondary central gear 50886, and then transmits the power to the power output shaft 5089 for output, so as to form a two-stage reduction.

[0151] Similarly, the deceleration requirement can be achieved by using a matching center gear, planetary gears, and planetary carrier. The appropriate number of matching center gears, planetary gears, and planetary carriers can be set according to the deceleration requirement, which will not be elaborated here.

[0152] In summary, the roller brush 500b provided in this application can cut away tangled material that may be wrapped around the roller brush by rotating the first cutter body 5051 relative to the second cutter body 5052 in the two sets of cutting components. This reduces the tangled material on the roller brush surface, improves the cleanliness of the roller brush surface, reduces the resistance of the roller brush operation, and avoids affecting the operation of the roller brush. At the same time, it also improves the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment and has good practicality.

[0153] Figure 30 This is a schematic diagram of another type of roller brush 500c according to this application. (Combined with...) Figure 30 This application provides a roller brush 500c, which includes a cutting assembly composed of two blades 505. One blade 505 is fixedly mounted, while the other blade 505 is reciprocating, allowing the two blades 505 to reciprocate relative to each other. This reciprocating motion cuts away any material that may be entangled on the roller brush, thereby reducing the amount of material on the roller brush surface and improving its cleanliness. This avoids affecting the operation of the roller brush and improves the cleaning effect of the cleaning equipment. The following is an illustration... Figure 30 -Appendix Figure 37 Further details regarding the 500c roller brush are described below.

[0154] Figure 30 The roller brush 500c shown is a type of roller brush 500, similar to roller brushes 500a and 500b. The roller brush 500c also includes a brush body 501, a cleaning component 503, and protective teeth 506. Unless otherwise specified, the structure and function of these components in the roller brush 500b are roughly the same as those of the roller brushes described above. Therefore, the corresponding descriptions of the roller brushes described above can be referred to, and will not be repeated here.

[0155] Figure 31 for Figure 30 A schematic diagram of the radial section of brush body 501. (Combined with...) Figure 31 The brush body 501 has a cutting groove 504 on its periphery, which penetrates the inner and outer periphery of the brush body 501 and is connected to the interior of the brush body 501. The cutting edges of the two blades 505 protrude at least partially from the cutting groove 504 to cut the wrapped material on the brush body 501.

[0156] Combination Figure 31In one embodiment, the brush body 501 has two cutting grooves 504 on its periphery, which are arranged to communicate with each other. At least a portion of the cutting edges of the two blades 505 protrudes from the two cutting grooves 504 to simultaneously cut the material wrapped around the brush body 501, thereby improving cutting efficiency. In another embodiment, the brush body 501 has one cutting groove 504 on its periphery, which also allows the cutting edges of the blades 505 protruding from the cutting groove 504 to cut the material wrapped around the brush body 501.

[0157] For the setting position and shape of the cutting groove 504 in the roller brush 500c, please refer to the relevant description of the cutting groove 504 in the roller brush 500b, which will not be repeated here.

[0158] Figure 32 for Figure 30 Internal diagram, Figure 33 for Figure 32 A structural diagram from another perspective. Combined with... Figures 30-32 The cutting assembly of the roller brush 500c includes a first blade 5051 and a second blade 5052 disposed within the brush body 501. The first blade 5051 is fixedly disposed relative to the brush body 501, and the second blade 5052 is arranged opposite to the first blade 5051. The second blade 5052 can reciprocate within the brush body 501, so that the second blade 5052 reciprocates relative to the first blade 5051. At least a portion of the cutting edges on the periphery of the first blade 5051 and the second blade 5052 are provided with protruding cutting grooves 504 to cut off the entanglement that may be wrapped around the roller brush, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, avoiding affecting the operation of the roller brush, and improving the cleaning effect of the cleaning equipment. Meanwhile, since the second blade 5052 oscillates back and forth instead of rotating continuously in the same direction, it can prevent the sheared entangled material from entering between the two blades 505 and inside the brush body 501 as the blades 505 rotate, so as to avoid affecting the operation of the internal components of the blades 505 and the brush body 501.

[0159] Combination Figures 31-33The brush body 501 is provided with a receiving cavity 5013, which communicates with the cutting grooves 504 on both sides, and the cutting assembly is placed in the receiving cavity 5013. A support shaft 5054 is provided inside the brush body 501. The support shaft 5054 can be arranged along an axial direction perpendicular to the brush body 501. The middle part of the support shaft 5054 is placed in the receiving cavity 5013, and the two ends of the support shaft 5054 pass through the side wall of the receiving cavity 5013 and are connected to the inner wall of the brush body 501. In one embodiment, two first support members 5086 are provided inside the brush body 501. The first support member 5086 can be a bearing or a copper sleeve. The two ends of the support shaft 5054 are rotatably connected to the two first support members 5086, so that the support shaft 5054 can be rotatably set relative to the brush body 501. The first blade 5051 is loosely sleeved on the support shaft 5054. The second blade 5052 can be fixedly connected or loosely sleeved on the support shaft 5054, so that the second blade 5052 rotates synchronously with the support shaft 5054, or the second blade 5052 rotates around the support shaft 5054. In another embodiment, the two ends of the support shaft 5054 can be fixedly connected to the inner wall of the brush body 501 so that the support shaft 5054 is fixedly connected to the brush body 501. The first blade 5051 is gapped or fixedly connected to the support shaft 5054, and the second blade 5052 is gapped on the support shaft 5054 so that the second blade 5052 is rotatably connected to the fixed support shaft 5054 and rotates around the support shaft 5054.

[0160] Figure 34 for Figure 30 A structural schematic diagram of the first cutting tool body 5051. (Combined with...) Figure 34 The first blade 5051 is generally circular. To prevent the first blade 5051 from rotating, at least a portion of its periphery is provided with a first limiting protrusion 5058. This first limiting protrusion 5058 is inserted into the inner wall of the receiving cavity 5013 so that the first blade 5051 can be fixed relative to the brush body 501. In specific implementation, two first limiting protrusions 5058 are provided. The two first limiting protrusions 5058 are arranged opposite each other on the periphery of the first blade 5051 along a first direction. The cutting edge of the first blade 5051 is arranged opposite each other on the periphery of the first blade 5051 along a second direction. The second direction and the first direction are intersecting.

[0161] Figure 35 for Figure 30 A schematic diagram of the structure of the second cutter body 5052. (Combined with...) Figure 35The second blade 5052 is generally circular. Since the second blade 5052 reciprocates, cutting teeth can be provided on its circumferential side as cutting edges. These cutting teeth protrude from the cutting grooves 504 on the circumference of the brush body 501 and reciprocate within the holes of the cutting grooves 504 to cut any material that may be wrapped around the roller brush. In another embodiment, the cutting teeth can also be arranged on the circumference of the second blade 5052, i.e., the cutting teeth are annular, so that the circumference of the second blade 5052 serves as the cutting edge of the second blade 5052.

[0162] Figure 36 This is a schematic diagram of the assembly of the cutting component within the brush body 501. In one embodiment, the first blade 5051 and the second blade 5052 are fitted together to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding interference with the operation of the internal components of the brush body 501. In another embodiment, since the cleaning device's fan will suck away the cut hair during operation, a small gap may also exist between the first blade 5051 and the second blade 5052.

[0163] Combination Figure 36 Under long-term use of the cleaning equipment, due to the reciprocating swing of the second blade 5052 relative to the first blade 5051 and their close fit, the first blade 5051 or / and the second blade 5052 will experience certain wear, which may lead to gaps between them. Based on this, this application provides an elastic element 507 between the outer side of at least one of the first blade 5051 and the second blade 5052 and the receiving cavity 5013. The elastic element 507 can compensate for the wear of the first blade 5051 or / and the second blade 5052, keeping the first blade 5051 and the second blade 5052 in close fit, so as to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

[0164] Combination Figure 36In one embodiment, the elastic element 507 is disposed between the outer side of the second blade 5052 and the side wall of the receiving cavity 5013. To prevent the elastic element 507 from rotating with the second blade 5052, at least a second limiting protrusion 5071 is provided on the periphery of the elastic element 507, so that the elastic element 507 has a non-circular structure. The second limiting protrusion 5071 on the periphery of the elastic element 507 abuts against the inner wall of the receiving cavity 5013, so that the second elastic element 507 can be fixed relative to the brush body 501 to compensate for the wear of the first blade 5051 and / or the second blade 5052, and keep the first blade 5051 and the second blade 5052 in contact. In a specific implementation, two second limiting protrusions 5071 are provided, and the two second limiting protrusions 5071 are arranged opposite to each other on the periphery of the elastic element 507. In another embodiment, the elastic element 507 may also be disposed between the outer side of the first blade 5051 and the side wall of the receiving cavity 5013, or the elastic element 507 may be disposed between the outer side of the first blade 5051 and the second blade 5052 and the side wall of the receiving cavity 5013.

[0165] Figure 37 for Figure 30 The diagram shows the assembly of the transmission component 508 and the second cutter body 5052. (Combined with...) Figure 37 The roller brush also includes a transmission assembly 508, which is disposed inside the brush body 501. The transmission assembly 508 is connected to the second blade body 5052. The transmission assembly 508 drives the second blade body 5052 to swing back and forth relative to the first blade body 5051 to cut the entangled material that may be wrapped around the roller brush.

[0166] Combination Figure 37 According to one embodiment of this application, the transmission assembly 508 includes a drive member 5081, a first drive shaft 50810, a second drive shaft 50811, and a swing arm 5082. The drive member 5081 is provided with a rotatable drive portion. The first drive shaft 50810 is eccentrically connected to the drive portion of the drive member 5081, and the second drive shaft 50811 is eccentrically connected to the second cutter body 5052. Both ends of the swing arm 5082 are rotatably connected to the first drive shaft 50810 and the second drive shaft 50811, respectively. When the drive member 5081 rotates, the second cutter body 5052 reciprocates through the cooperation of the two eccentric drive shafts and the swing arm 5082.

[0167] Combination Figure 37In one embodiment, the drive member 5081 includes a power input shaft 5087, a worm gear mechanism 50812, and a first transmission wheel 50813. The power input shaft 5087 is housed within the brush body 501. The worm of the worm gear mechanism 50812 is connected to the power input shaft 5087, and the worm gear is rotatably connected within the brush body 501. The first transmission wheel 50813 is rotatably connected within the brush body 501 and is connected to the worm gear via a transmission connection. The first transmission wheel 50813 is configured as a drive unit, and a first drive shaft 50810 is connected to the end face of the first transmission wheel 50813. When the power input shaft 5087 rotates, the first transmission wheel 50813 is driven to rotate via the transmission energy of the worm gear mechanism 50812, thereby driving the second cutter body 5052 to reciprocate through the swing arm 5082.

[0168] Combination Figure 37 One end of the power input shaft 5087 can be connected to the support seat 502 at the other end of the brush body 501. When the roller brush moves and rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501, driving the worm gear mechanism 50812, the first transmission wheel 50813 and the swing arm 5082 to move, and then driving the second cutter body 5052 to swing back and forth.

[0169] Combination Figure 37 One or more first and second support members 514 can be provided inside the brush body 501. The power input shaft 5087 rotatably passes through the second support member 514 to support the power input shaft 5087. The second support member 514 can be a bearing or a copper sleeve to ensure that the power input shaft 5087 can rotate stably within the second support member 514. In specific implementations, the number of second support members 514 can be set according to the length of the power input shaft 5087. If the power input shaft 5087 is long, multiple second support members 514 can be provided; if the drive shaft is short, only one second support member 514 can be provided.

[0170] Combination Figure 37 The power input shaft 5087 is arranged along the axial direction of the brush body 501, and the central axis of the first transmission wheel 50813 is perpendicular to the axial direction of the brush body 501. That is, the central axis of the first transmission wheel 50813 and the power input shaft 5087 are arranged perpendicularly. The power of the power input shaft 5087 is transmitted to the first transmission wheel 50813 through the worm gear mechanism 50812 to drive the first transmission wheel 50813 to rotate. The worm gear mechanism 50812 has the characteristics of smooth operation, low impact, vibration and noise, and can adapt to the assembly in the narrow space inside the brush body 501.

[0171] In one embodiment, combined with Figure 37The transmission assembly 508 also includes a central gear 50814, which is coaxially connected to the worm gear. That is, the central gear 50814 and the worm gear share a central shaft, allowing them to rotate synchronously. The reason for providing the central gear 50814 is that, since the worm gear and the first transmission wheel 50813 are not on the same plane, power transmission between them is achieved through the central gear 50814, which is on the same plane as the first transmission wheel 50813. In another embodiment, if the worm gear and the first transmission wheel 50813 are on the same plane, the worm gear can directly mesh with the first transmission wheel 50813, eliminating the need for the central gear 50814.

[0172] Combination Figure 37 In one embodiment, the transmission assembly 508 further includes a second transmission wheel 50815, which is rotatably connected inside the brush body 501 and connected to both the intermediate gear 50814 and the first transmission wheel 50813. The second transmission wheel 50815 is positioned upstream of the first transmission wheel 50813, and its radius is smaller than that of the first transmission wheel 50813. This arrangement of the second transmission wheel 50815 adapts to the internal space of the brush body 501. Furthermore, the second transmission wheel 50815 and the first transmission wheel 50813 form a speed reduction mechanism, thereby reducing the rotational speed of the first transmission wheel 50813 and correspondingly reducing the reciprocating oscillation speed of the second blade 5052. This reduces noise and wear on both the first and second blades 5051 and 5052, demonstrating good practicality. In another embodiment, if the internal space of the brush body 501 allows, the first transmission wheel 50813 can also directly mesh with the intermediate gear 50814 for transmission.

[0173] Combination Figure 37 The first transmission wheel 50813 is fixedly connected to the first drive shaft 50810 by means of key connection or other means. Both ends of the first drive shaft 50810 are rotatably connected inside the brush body 501. One end of the swing arm 5082 is eccentrically connected to the first drive shaft 50810. When the first transmission wheel 50813 is driven to rotate, it drives the first drive shaft 50810 to rotate synchronously, thereby driving the swing arm 5082 to move. To ensure smooth rotation of the first drive shaft 50810, two third support members 515 are provided inside the brush body 501. Both ends of the first drive shaft 50810 are rotatably connected to the two third support members 515, which can be bearings or copper sleeves.

[0174] Combination Figure 37In one embodiment, the second cutter body 5052 is eccentrically provided with a connecting hole. One end of the second drive shaft 50811 can be assembled into the connecting hole of the second cutter body 5052 by means of threaded connection or key connection. One end of the swing arm 5082 is rotatably sleeved on the other end of the second drive shaft 50811. In order to make the swing arm 5082 rotate smoothly on the second drive shaft 50811, a wear-resistant part can be provided between the swing arm 5082 and the second drive shaft 50811. The wear-resistant part can include a copper sleeve or a bearing. In another embodiment, the second drive shaft 50811 can also be integrally formed and connected to the second cutter body 5052.

[0175] In summary, the roller brush 500c provided in this application, through the cooperation of a fixedly set first blade 5051 and a second blade 5052 that can reciprocate relative to the first blade 5051, can cut off the entangled material that may be wrapped around the roller brush, reduce the entangled material on the roller brush surface, improve the cleanliness of the roller brush surface, reduce the resistance of the roller brush operation, so as to avoid affecting the operation of the roller brush, and at the same time improve the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment, and has good practicality.

[0176] Figure 38 This is a schematic diagram of another type of roller brush 500d according to this application. (Combined with...) Figure 38 This application provides a roller brush 500d, which includes two blades 505. One blade 505 is fixedly mounted, while the other blade 505 is rotatably mounted, allowing the two blades 505 to rotate relative to each other. This cuts away any material that may be entangled on the roller brush, reducing the amount of material on the brush surface and improving its cleanliness. This avoids affecting the operation of the roller brush and improves the cleaning effect of the cleaning equipment. The following is an illustration... Figure 38 - Appendix Figure 44 The specific details of the roller brush are further described below.

[0177] Figure 38 The roller brush 500d shown is a type of roller brush 500, similar to roller brush 500c. The main difference between the two is that the blade of roller brush 500d is rotating, while the blade of roller brush 500c is reciprocating. Roller brush 500d also includes a brush body 501, a cleaning component 503, a cutting groove 504, and protective teeth 506. Unless otherwise specified, the structure and function of these components in roller brush 500b are largely the same as those in roller brush 500c, and therefore can be referred to the corresponding description of the roller brushes above, which will not be repeated here.

[0178] Figure 39 for Figure 38 A schematic diagram of the radial cross-section. Combined with... Figure 39The blade body 505 of the roller brush 500d includes a first blade body 5051 and a second blade body 5052 disposed within the brush body 501. The first blade body 5051 is fixedly disposed relative to the brush body 501, and the second blade body 5052 is arranged opposite to the first blade body 5051. The second blade body 5052 can rotate within the brush body 501 so that the second blade body 5052 rotates relative to the first blade body 5051. At least a portion of the cutting edges on the periphery of the first blade body 5051 and the second blade body 5052 are provided with protruding cutting grooves 504 to cut off the entanglement that may be wrapped around the roller brush, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, avoiding affecting the operation of the roller brush, and improving the cleaning effect of the cleaning equipment.

[0179] Figure 40 for Figure 38 An internal diagram. Combined with... Figure 39 as well as Figure 40 The brush body 501 is provided with a receiving cavity 5013, which communicates with the cutting grooves 504 on both sides, and the cutting assembly is placed inside the receiving cavity 5013. A support shaft 5054 is provided inside the brush body 501. The support shaft 5054 can be arranged along an axial direction perpendicular to the brush body 501. The middle part of the support shaft 5054 is placed inside the receiving cavity 5013, and both ends of the support shaft 5054 pass through the side walls of the receiving cavity 5013 and are connected to the inner wall of the brush body 501. In one embodiment, two first support members 5086 are provided inside the brush body 501. The first support member 5086 can be a bearing or a copper sleeve. Both ends of the support shaft 5054 are rotatably connected to the two first support members 5086, so that the support shaft 5054 can be rotatably arranged relative to the brush body 501. The first cutter body 5051 is fitted onto the support shaft 5054 with a gap so that the first cutter body 5051 remains fixed when the support shaft 5054 rotates. The second cutter body 5052 can be connected to the support shaft 5054 by a key connection so that the second cutter body 5052 and the support shaft 5054 are fixedly connected. When the support shaft 5054 rotates, the second cutter body 5052 rotates synchronously with the support shaft 5054.

[0180] Figure 41 for Figure 38 A structural schematic diagram of the first cutting tool body 5051. (Combined with...) Figure 41 The first blade body 5051 is generally circular. To prevent the first blade body 5051 from rotating, at least a portion of its periphery is provided with a first limiting protrusion 5058. This first limiting protrusion 5058 abuts against the inner wall of the receiving cavity 5013, so that the first blade body 5051 can be fixed relative to the brush body 501. In specific implementation, two first limiting protrusions 5058 are provided. The two first limiting protrusions 5058 are arranged opposite each other on the periphery of the first blade body 5051 along a first direction, and the cutting blade is arranged opposite each other on the periphery of the first blade body 5051 along a second direction. The first direction and the second direction intersect.

[0181] Figure 42 for Figure 38 A schematic diagram of the structure of the second cutter body 5052. (Combined with...) Figure 42 The second blade 5052 is generally circular. Since the second blade 5052 is rotatably arranged, in one embodiment, cutting teeth can be provided on the circumferential portion of the second blade 5052 to serve as cutting edges. The cutting teeth on the circumferential side of the second blade 5052 protrude from the cutting groove 504 on the circumference of the brush body 501 and rotate within the cutting groove 504 to cooperate with the fixed first blade 5051 to intermittently cut the material that may be wrapped around the roller brush. In another embodiment, the cutting teeth can be provided on the circumference of the second blade 5052, i.e., the cutting teeth are annular, to continuously cut the material that may be wrapped around the roller brush.

[0182] Figure 43 This is a schematic diagram showing the assembly of the blade body 505 within the brush body 501. (Combined with...) Figure 43 The first blade 5051 and the second blade 5052 are fitted together to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding interference with the operation of the internal components of the brush body 501. In another embodiment, since the cleaning device's fan will suck away the cut hair during operation, a small gap may also exist between the first blade 5051 and the second blade 5052.

[0183] Combination Figure 43 Under long-term use of cleaning equipment, the second blade 5052 rotates relative to the first blade 5051, and the two are arranged in close contact. The first blade 5051 or / and the second blade 5052 will experience certain wear, which may cause gaps between them. Based on this, the roller brush of this application also includes an elastic element 507. The elastic element 507 can compensate for the wear of the first blade 5051 or / and the second blade 5052, so that the first blade 5051 and the second blade 5052 remain in close contact, so as to prevent the cut hair from entering the brush body 501 through the gap between the first blade 5051 and the second blade 5052, thus avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

[0184] Combination Figure 43An elastic element 507 is disposed between the side of the second blade 5052 facing away from the first blade 5051 and the brush body 501 to compensate for the wear of the first blade 5051 and / or the second blade 5052, keeping the first blade 5051 and the second blade 5052 in close contact. In a specific implementation, the elastic element 507 can be a ring-shaped structure, with its gap sleeved on the support shaft 5054 so that it rotates around the support shaft 5054 with the second blade 5052, and the elastic element 507 is fixedly assembled on the side wall of the receiving cavity 5013 to compensate for the wear of the first blade 5051 and / or the second blade 5052.

[0185] Combination Figure 43 The side wall of the receiving cavity 5013 is provided with an assembly part 50132. The assembly part 50132 can be a hole-shaped structure or a groove-shaped structure. Part of the elastic member 507 is placed in the assembly part 50132 by means of bonding, interference fit, etc. The other part of the elastic member 507 abuts against the second cutter body 5052 to compensate for the wear of the first cutter body 5051 and / or the second cutter body 5052, so as to ensure that the first cutter body 5051 and the second cutter body 5052 fit together.

[0186] Figure 44 This is a schematic diagram of the assembly of the transmission component 508 and the second cutter body 5052. (Combined with...) Figure 44 The roller brush also includes a transmission assembly 508, which is housed within the brush body 501 and connected to a second blade 5052. The transmission assembly 508 drives the second blade 5052 to rotate relative to the first blade 5051, thereby cutting any material that may be entangled on the roller brush. The specific details of the transmission assembly 508 are now further described with reference to the accompanying drawings.

[0187] Combination Figure 44 According to one embodiment of this application, the transmission assembly 508 includes a drive member 5081 and a worm gear mechanism 50812. The drive member 5081 is provided with a rotatable drive part. The worm of the worm gear mechanism 50812 is connected to the drive part in a transmission manner. The worm gear is rotatably connected to the brush body 501 around the support shaft 5054. In one embodiment, the second cutter body 5052 is connected to the support shaft 5054. When the drive member 5081 rotates, the support shaft 5054 is driven to rotate by the worm gear mechanism 50812, so as to drive the second cutter body 5052 connected to the support shaft 5054 to rotate. The rotating second cutter body 5052 cooperates with the fixed first cutter body 5051 to cut the entanglement that may be wrapped around the roller brush. In another embodiment, the second cutter body 5052 is directly connected to the turbine. When the turbine rotates, it directly drives the second cutter body 5052 to rotate synchronously with the turbine. The rotating second cutter body 5052 cooperates with the fixed first cutter body 5051 to cut the entangled material that may be wrapped around the roller brush.

[0188] Combination Figure 43In one embodiment, a fixed first cutter body 5051 is disposed between a rotatable second cutter body 5052 and a worm gear mechanism 50812 to facilitate the arrangement of the elastic element 507. In another embodiment, if the internal space of the brush body 501 allows, the rotatable second cutter body 5052 can also be disposed between the fixed first cutter body 5051 and the worm gear mechanism 50812.

[0189] Combination Figure 44 According to one embodiment of this application, the worm can be arranged along an axial direction parallel to the brush body 501. Two fourth support members 516 are provided in the brush body 501. The fourth support member 516 can be a bearing or a copper sleeve. The two ends of the worm are rotatably connected to the two fourth support members 516 so that the worm can be rotatably arranged relative to the brush body 501.

[0190] Combination Figure 44 The driving component 5081 includes a power input shaft 5087, a first transmission wheel 50813, and a second transmission wheel 50815. The first transmission wheel 50813 is connected to the power input shaft 5087 and is configured as a driving unit. The second transmission wheel 50815 is connected to the worm gear and meshes with the first transmission wheel 50813. When the power input shaft 5087 rotates, the meshing transmission of the first transmission wheel 50813 and the second transmission wheel 50815 drives the worm gear mechanism 50812 to operate, which in turn drives the second cutter body 5052 to rotate, thereby cutting any material that may be wrapped around the brush.

[0191] Combination Figure 44 One end of the power input shaft 5087 can be connected to the support seat 502 at the other end of the brush body 501. When the roller brush moves and rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501, driving the worm gear mechanism 50812 to move, and then driving the second cutter body 5052 to rotate, so as to cut the entanglement that may be wrapped on the roller brush.

[0192] Combination Figure 44 One or more second support members 514 can be provided inside the brush body 501. The power input shaft 5087 rotatably passes through the second support member 514 to support the power input shaft 5087. The second support member 514 can be a bearing or a copper sleeve to ensure that the power input shaft 5087 can rotate stably within the support member. In specific implementations, the number of second support members 514 can be set according to the length of the power input shaft 5087. If the power input shaft 5087 is long, multiple second support members 514 can be provided; if the power input shaft 5087 is short, only one second support member 514 can be provided.

[0193] Combination Figure 44 Since the power input shaft 5087 is driven by the worm gear of the worm gear mechanism 50812 through the meshing first transmission wheel 50813 and second transmission wheel 50815, and the power input shaft 5087 is coaxially arranged with the central axis of the brush body 501, the worm gear of the worm gear mechanism 50812 can be offset from the central axis of the brush body 501. This provides more space for arranging the cutter body 505, allowing the cutting assembly to be arranged as close as possible to the center of the brush body 501, thereby improving the shearing effect on any material that may be wrapped around the roller brush. In other embodiments, if the worm gear mechanism can also be directly connected to the power input shaft 5087, it can also drive the second cutter body 5052 to be rotatably arranged relative to the first cutter body 5051.

[0194] Combination Figure 44 The radius of the second transmission wheel 50815 is larger than that of the first transmission wheel 50813 to reduce the rotational speed of the second transmission wheel 50815. Correspondingly, the output speed of the worm gear mechanism is also reduced, as is the rotational speed of the second cutter body 5052. This reduces the noise of the cleaning equipment and reduces the wear of the first cutter body 5051 and the second cutter body 5052, making it highly practical.

[0195] The transmission assembly 508 provided in this application uses a worm gear mechanism 50812 for power transmission. The worm gear mechanism 50812 has the characteristics of smooth operation, low impact, vibration and noise, and can adapt to the assembly in the narrow space inside the brush body 501.

[0196] In summary, the roller brush 500d provided in this application, through the cooperation of a fixed first cutter body 5051 and a second cutter body 5052 that can rotate relative to the first cutter body 5051, can cut off the entangled material that may be wrapped around the roller brush, reduce the entangled material on the roller brush surface, improve the cleanliness of the roller brush surface, thereby reducing the resistance of the roller brush operation to avoid affecting the operation of the roller brush. At the same time, it also improves the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment, and has good practicality.

[0197] Figure 45 This is a schematic diagram of another type of roller brush 500e according to this application. (Combined with...) Figure 45 This application provides a roller brush 500e, which includes at least one reciprocating blade 505. The cutting edge of the reciprocating blade 505 can cut away any debris that may be wrapped around the roller brush, thereby reducing the debris on the roller brush surface, improving the cleanliness of the roller brush surface, and avoiding affecting the operation of the roller brush, thus improving the cleaning effect of the cleaning equipment. Specific details of the roller brush are now further described with reference to the accompanying drawings. Figure 45 -Appendix Figure 53 The specific details of the roller brush are further described below.

[0198] Figure 45 The roller brush 500e shown is a type of roller brush 500, similar to roller brush 500a. The main difference is that the blade 505 of roller brush 500e is reciprocating, while the blade 505 of roller brush 500a is oscillating. Roller brush 500e also includes a brush body 501, a cleaning component 503, a cutting groove 504, and protective teeth 506. Unless otherwise specified, the structure and function of these components in roller brush 500e are largely the same as those in roller brush 500d described above; therefore, please refer to the corresponding description of the roller brushes above, and it will not be repeated here.

[0199] Figure 46 for Figure 45 A radial cross-sectional schematic diagram, combined with Figure 45 as well as Figure 46 The brush body 501 has a cutting groove 504 on its periphery, which is connected to the inside of the brush body 501. At least part of the cutting edge of the blade body 505 is placed in the cutting groove 504 to cut the wrapped material on the brush body 501.

[0200] Combination Figure 45 as well as Figure 46 The cutting groove 504 can be roughly elongated and can be arranged on the periphery of the brush body 501 along an axial direction parallel to the brush body 501. The length of the cutting groove 504 is slightly less than the axial length of the brush body 501, so that the cutting groove 504 has a longer length, allowing the cutter body 505 to have a sufficient range of reciprocating movement within the cutting groove 504, ensuring the cutting effect on the material wrapped around the brush body 501.

[0201] Combination Figure 45 as well as Figure 46 The blade body 505 is placed inside the brush body 501. At least a portion of the cutting edge on the periphery of the blade body 505 protrudes from the cutting groove 504. The blade body 505 can move back and forth within the cutting groove 504 to cut off the entanglement that may be wrapped around the roller brush, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, so as to avoid affecting the operation of the roller brush and improve the cleaning effect of the cleaning equipment.

[0202] Figure 47 for Figure 45 The diagram shows the assembly of the cutter body 505 and the transmission assembly 508. (Combined with...) Figure 47 The roller brush also includes a transmission assembly 508, which is located inside the brush body 501. The transmission assembly 508 includes a drive shaft 5084 and a cam 50816. The drive shaft 5084 is rotatably located inside the brush body 501, and at least one cam 50816 is connected to the drive shaft 5084 so that the cam 50816 rotates synchronously with the drive shaft 5084.

[0203] Combination Figure 47The blade body 505 is provided with a driven part, and the cam 50816 is provided with two or more positioning parts on its periphery. The two or more positioning parts are spaced apart along the axial direction of the cam 50816, and at least part of the two or more positioning parts are staggered along the periphery of the cam 50816. The two or more positioning parts cooperate with the driven part. Under the condition that the drive shaft 5084 drives the cam 50816 to rotate synchronously, the cam 50816 drives the blade body 505 to reciprocate relative to the brush body 501 to cut the entanglement that may be wrapped on the roller brush, reduce the entanglement on the roller brush surface, improve the cleanliness of the roller brush surface, reduce the resistance of the roller brush operation, so as to avoid affecting the operation of the roller brush. At the same time, it also improves the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment and having good practicality.

[0204] It should be noted that, in this application, "two or more positioning parts are spaced apart along the axial direction of the cam 50816" means that, along the axial direction of the cam 50816, two or more positioning parts are sequentially arranged on the circumference of the cam 50816. "At least part of two or more positioning parts are staggered along the circumference of the cam 50816" means that, along the axial direction of the cam 50816, the projections of two or more positioning parts at least do not overlap, so that two or more positioning parts can cooperate with the driven part to drive the cutter body 505 to reciprocate relative to the brush body 501. The details of the cooperation between the cam 50816 and the cutter body 505 are now further described with reference to the accompanying drawings.

[0205] Figure 48 for Figure 47 A schematic diagram of the structure of cam 50816 in the diagram. Figure 49 for Figure 47 A structural schematic diagram of the blade 505. (Combined with...) Figures 47-49In one embodiment, at least a portion of the circumferential side of the cam 50816 is provided with a first protrusion 50817. The first protrusion 50817 has two or more positioning portions in the axial direction of the cam 50816. Correspondingly, the blade body 505 is provided with a first recess 50511. At least a portion of the first protrusion 50817 rotates within the first recess 50511, and the first recess 50511 is configured as a driven portion. During the rotation of the drive shaft 5084, the first protrusion 50817 rotates synchronously within the first recess 50511. Since the first protrusion 50817 has two or more of the aforementioned positioning portions in the axial direction of the cam 50816, it can drive the blade body 505, which is provided with the first recess 50511, to reciprocate relative to the brush body 501 to cut any material that may be wrapped around the roller brush. In a specific implementation, the first protrusion 50817 can be arranged in a ring around the periphery of the cam 50816 so that the drive shaft 5084 can rotate in a set direction and drive the blade body 505 to reciprocate relative to the brush body 501; or, the first protrusion 50817 can also be provided only on the periphery of the cam 50816, and the blade body 505 can also be driven to reciprocate relative to the brush body 501 by the rotation of the drive shaft 5084.

[0206] Combination Figure 48 In one embodiment, a portion of the blade body 505 is placed inside the brush body 501, and another portion (cutting edge) of the blade body 505 protrudes from the cutting groove 504 on the brush body 501. Two first connecting protrusions 50512 are provided on the side of the blade body 505 located inside the brush body 501, and the two first connecting protrusions 50512 together with the blade body 505 form the aforementioned first recess 50511. In another embodiment, a groove can also be directly formed on the side of the blade body 505 located inside the brush body 501 to serve as the aforementioned first protrusion 50817.

[0207] Combination Figure 49 In one embodiment, at least a portion of the first protrusion 50817 has a helical structure, which enables the cutter body 505 to reciprocate linearly when the drive shaft 5084 rotates, improving the smoothness of the cutter body 505's movement. The first protrusion 50817 having at least a helical structure means that the first protrusion 50817 is entirely helical, or that a portion of the first protrusion 50817 has a helical structure, while another portion of the first protrusion 50817 may have a planar structure. In another embodiment, at least a portion of the first protrusion 50817 has an inclined plane structure or an inclined plane structure, or is one or a combination of two or more of the following: a helical structure, an inclined plane structure, and an inclined plane structure.

[0208] Combination Figure 48 as well as Figure 49In one embodiment, the first protrusion 50817 and the first recess 50511 are arranged in a one-to-one correspondence, that is, the reciprocating movement of the blade body 505 relative to the brush body 501 is driven by the movement of one first protrusion 50817 within the corresponding first recess 50511. In another embodiment, multiple first protrusions 50817 and first recesses 50511 can also be arranged in a one-to-one correspondence, that is, the reciprocating movement of the blade body 505 relative to the brush body 501 is driven by the movement of multiple first protrusions 50817 within the corresponding first recesses 50511. In specific implementation, multiple first protrusions 50817 can be integrated on one cam 50816, or each cam 50816 can be integrated with one first protrusion 50817. By setting multiple cams 50816, multiple first protrusions 50817 can be provided.

[0209] Figure 50 for Figure 47 Another structural schematic diagram of cam 50816 in the diagram. Figure 51 for Figure 47 Another structural schematic diagram of the blade body 505. Combined with... Figure 50 as well as Figure 51 In another embodiment, at least a portion of the circumferential side of the cam 50816 is provided with a second recess 50818, the second recess 50818 having two or more positioning portions in the axial direction of the cam 50816; correspondingly, the blade body 505 is provided with a second protrusion 50513, the second protrusion 50513 being integrally formed and connected to the side of the blade body 505 located within the brush body 501, at least a portion of the second protrusion 50513 rotating within the second recess 50818, the second recess 50818 being configured as a driven portion. During the rotation of the drive shaft 5084, the second protrusion 50513 moves within the rotating second recess 50818. Since the second recess 50818 has two or more of the aforementioned positioning portions in the axial direction of the cam 50816, the blade body 505 provided with the second recess 50818 can be driven to reciprocate relative to the brush body 501 to cut any material that may be wrapped around the roller brush. In a specific implementation, the second recess 50818 can be arranged in a ring around the periphery of the cam 50816 so that the drive shaft 5084 can rotate in a set direction and drive the blade body 505 to reciprocate relative to the brush body 501; or, the second recess 50818 can be provided only on the periphery of the cam 50816, and the blade body 505 can also be driven to reciprocate relative to the brush body 501 by the rotation of the drive shaft 5084.

[0210] Combination Figure 50 as well as Figure 51In one embodiment, at least a portion of the second recess 50818 has a helical structure, which enables the cutter body 505 to reciprocate linearly when the drive shaft 5084 rotates, improving the smoothness of the cutter body 505's movement. The helical structure of at least a portion of the second recess 50818 means that the second recess 50818 is entirely helical, or that a portion of the second recess 50818 is helical, while the other portion of the second recess may be planar. In another embodiment, at least a portion of the second recess 50818 has a sloped structure or a combination of one or more of the following structures: helical, sloped, and sloped.

[0211] Combination Figure 50 as well as Figure 51 In one embodiment, the second protrusion 50513 and the second recess 50818 are arranged in a one-to-one correspondence, that is, the reciprocating movement of the blade body 505 relative to the brush body 501 is driven by the movement of one second protrusion 50513 within the corresponding second recess 50818. In another embodiment, multiple second protrusions 50513 and second recesses 50818 can also be arranged in a one-to-one correspondence, that is, the reciprocating movement of the blade body 505 relative to the brush body 501 is driven by the movement of multiple second protrusions 50513 within the corresponding second recesses 50818. In specific implementation, multiple second protrusions 50513 can be integrated on one cam 50816, or each cam 50816 can be integrated with one second protrusion 50513. By setting multiple cams 50816, multiple second protrusions 50513 are provided.

[0212] Combination Figure 46 as well as Figure 47 The cutting assembly includes two or more blades 505, at least one of which has a driven part. A cam 50816 and the blades 505 with driven parts are correspondingly arranged one-to-one. Two or more positioning parts on the cam 50816 cooperate with the driven parts on the corresponding blades 505 to drive the corresponding blades 505 to reciprocate relative to the brush body 501. That is, in each cutting assembly, at least one blade 505 with a driven part is ensured to reciprocate relative to the brush body 501 to cut the material that may be wrapped around the roller brush. The remaining blades 505 can be fixed relative to the brush body 501 or can move relative to the brush body 501 to cooperate with the blades 505 with driven parts to cut the material that may be wrapped around the roller brush, thus improving the cutting efficiency of the wrapped material. In each cutting assembly, since two or more blades 505 reciprocate relative to the brush body 501, the cutting efficiency of the wrapped material is improved.

[0213] Combination Figure 46 as well as Figure 47Each cutting assembly includes two blades 505. Both blades 505 have the aforementioned driven part on one side inside the brush body 501. Correspondingly, the cam 50816 on the drive shaft 5084 includes two cams 50816 arranged at intervals. The positioning parts on the two cams 50816 respectively cooperate with the driven parts of the blades 505. When the drive shaft 5084 rotates, it drives the two blades 505 to move relative to the brush body 501 to cut the entanglement that may be wrapped around the roller brush.

[0214] Combination Figure 47 In one embodiment, each cutting assembly has at least two relatively movable blades 505 to shear material that may be wrapped around the roller brush by mutual shearing, thereby further improving the shearing effect on the wrapped material. In specific implementation, two cams 50816 that cooperate with the two relatively movable blades 505 are symmetrically arranged about an axis perpendicular to the drive shaft 5084. While the drive shaft 5084 rotates, the cams 50816 on the two blades 505 respectively drive the two blades 505 to move relative to each other.

[0215] In another embodiment, in each cutting assembly, two or more blades 505 can also reciprocate in the same direction. When two or more blades 505 reciprocate in the same direction, it is preferable that the two or more blades 505 have a speed difference. For example, the first blade 505 reciprocates at a first speed, and the second blade 505 reciprocates at a second speed, with the first speed being greater than the second speed. By having a speed difference between the first and second blades 505, the material that may be wrapped around the roller brush can be cut by mutual shearing, further improving the cutting effect on the wrapped material. In specific implementation, the speed difference between the two blades 505 moving in the same direction can be achieved by using different shapes of the cams 50816 that cooperate with the two or more blades 505. For example, this can be achieved by different inclination angles of the spiral structure, inclination degrees of the inclined surface structure, or central angles of the arc surface structure of the first protrusion 50817 or the first concave surface 50511 on the cam 50816. No limitation is imposed here.

[0216] It should be noted that in each cutting assembly, there may be only one type of two relatively moving blades 505 and two reciprocating blades 505 in the same direction, or both types may exist. If both types exist, it is only necessary to set three or more blades 505 and cams 50816 that cooperate with the blades 505. The specific driving method can be referred to the above description, and will not be repeated here.

[0217] Combination Figure 47A first guide portion 50514 is provided on the blade 505 that reciprocates relative to the brush body 501, and a second guide portion 517 is provided inside the brush body 501. Of the first guide portion 50514 and the second guide portion 517, one is a guide shaft and the other is a guide recess. The guide recess is arranged axially parallel to the drive shaft 5084, and the guide shaft reciprocates within the guide recess. Under the condition that the blade 505 reciprocates on the drive shaft 5084, the guide shaft reciprocates within the guide recess to guide the reciprocating movement of the blade 505, causing the blade 505 to reciprocate along a predetermined direction. Furthermore, the guide shaft also allows the blade 505 to be supported and suspended within the brush body 501, preventing the blade 505 from detaching from the brush body 501 during brush operation.

[0218] Combination Figure 47 In one embodiment, a guide recess is provided on the blade 505 that reciprocates relative to the brush body 501. The guide recess can be a guide groove or a guide hole. The guide recess is configured as the first guide portion 50514 described above. A guide shaft is fixedly provided inside the brush body 501. For example, the two ends of the guide shaft are connected to the two side walls of the protective teeth. The guide shaft is configured as the second guide portion 517 described above. With two reciprocating blades 505, the guide recess is a guide hole, and the drive shaft 5084 can reciprocate within the guide holes of the two blades 505 to ensure the movement direction of the blades 505 through a single drive shaft 5084. In another embodiment, a guide recess is provided on the brush body 501, for example, on the side wall of the protective teeth. The guide recess can be a guide groove or a guide hole. The guide recess is configured as the second guide portion 517 described above. A guide shaft is fixedly provided on the reciprocating blade 505. The guide shaft is configured as the second guide portion 517 described above. With two reciprocating cutter bodies 505, two guide recesses are respectively arranged opposite each other, and the drive shafts 5084 on the two cutter bodies 505 reciprocate in the two guide recesses respectively to ensure the movement direction of the cutter bodies 505.

[0219] marry Figure 47 According to one embodiment of this application, multiple guide shafts are provided, and the line connecting at least two guide shafts intersects with the drive shaft 5084. For example, when three guide shafts are provided, the three guide shafts are arranged in a triangular pattern, that is, the three guide shafts are not on a straight line, which can further ensure the moving direction of the blade body 505 and further prevent the blade body 505 from falling off the brush body 501 during the operation of the roller brush.

[0220] Figure 52 for Figure 45 The diagram shows the assembly of the two tool bodies 505. (Combined with...) Figure 52According to one embodiment of this application, two or more blades 505 are stacked together, that is, two or more blades 505 are fitted together, so as to prevent the cut hair from entering the brush body 501 through the gap between adjacent blades 505, thus avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

[0221] Combination Figure 52 In the outermost layer, at least one of the two blades 505 has an elastic element 507 on its outer side. Under long-term use of the cleaning equipment, due to movement between adjacent blades 505 and their close fit, at least one of the blades 505 will experience wear, potentially creating gaps between them. Therefore, the elastic element 507 compensates for the wear of the adjacent blades 505, keeping them in close contact to prevent cut hair from entering the brush body 501 through the gaps between the blades 505 and thus affecting the operation of the internal components of the brush body 501.

[0222] Combination Figure 52 In one embodiment, in the two outer blades 505, an elastic element 507 is provided on the outer side of each blade 505. The elastic element 507 can fit against the side wall of the cutting groove 504. The elastic element 507 can be connected to the side wall of the cutting groove 504 or the blade 505 by means of adhesive or screw connection. While ensuring that the adjacent blades 505 fit together, the cutting groove 504 can also be filled by the elastic element 507 and the blades 505, preventing the cut hair from entering the brush body 501 through the cutting groove 504. In another embodiment, in the two outer blades 505, an elastic element 507 is provided on the outer side of one of the blades 505. This can also ensure that the adjacent blades 505 fit together, and the cutting groove 504 can also be filled by the elastic element 507 and the cutting component, preventing the cut hair from entering the brush body 501 through the cutting groove 504.

[0223] Figure 53 for Figure 47 A schematic diagram of the transmission component 508 in the diagram. (Combined with...) Figure 53The transmission assembly 508 includes a power input shaft 5087, a reduction mechanism 5088, and a power output shaft 5089 connected in sequence. The power output shaft 5089 is configured as a drive shaft 5084. The power input shaft 5087 is housed within the brush body 501 and is connected to the power output shaft 5089 via the reduction mechanism 5088. The power input shaft 5087 and the power output shaft 5089 are arranged axially along the brush body 501. Because they are connected via the reduction mechanism 5088, the rotational speed of the power output shaft 5089 can be reduced to a suitable range, thus reducing the rotational speed of the driven gear and the first cutter body 505, thereby reducing noise and wear on the first and second cutter bodies 505.

[0224] Combination Figure 53 One end of the power input shaft 5087 can be connected to the support seat at the other end of the brush body 501. When the roller brush moves and rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501 so as to transmit power to the main gear through the reduction mechanism 5088 and the power output shaft 5089 to drive the driven gear and the first cutter body 505 to rotate.

[0225] Combination Figure 53 One or more second support members 514 can be provided inside the brush body 501. The power input shaft 5087 rotatably passes through the second support member 514 to support the power input shaft 5087. The second support member 514 can be a bearing or a copper sleeve to ensure that the power input shaft 5087 can rotate stably within the second support member 514. In specific implementations, the number of second support members 514 can be set according to the length of the power input shaft 5087. If the power input shaft 5087 is long, multiple second support members 514 can be provided; if the drive shaft is short, only one second support member 514 can be provided. Similarly, a suitable number of second support members 514 can also be configured on the power input shaft 5089.

[0226] The reduction mechanism 5088 in the roller brush 500e can reduce the rotational speed of the power output shaft 5089 to a suitable range, and also reduce the rotational speed of the driven gear 5085 and the first cutter body 5051, thereby reducing noise and wear on the first cutter body 5051 and the second cutter body 5052. In specific implementation, the reduction mechanism 5088 in the roller brush 500e can be the same as the reduction mechanism 5088 in the roller brush 500b, that is, the reduction mechanism 5088 can be a planetary gear reducer. Planetary gear reducers are characterized by small size, high load capacity, and stable operation, and can adapt to the internal space of the brush body 501, ensuring stable power output. The planetary gear reducer can have one or more transmission stages; the more stages, the larger the reduction ratio. The number of stages can be set according to the reduction requirements. Specific structure details are described above and will not be repeated here.

[0227] In summary, the roller brush 500e provided in this application can cut away any entanglement that may be wrapped around the roller brush through at least one reciprocating blade 505, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, reducing the resistance of the roller brush operation to avoid affecting the operation of the roller brush, and at the same time improving the cleaning efficiency of the roller brush, thus improving the cleaning effect of the cleaning equipment, and has good practicality.

[0228] Figure 54 This is a schematic diagram of another type of roller brush 500f according to this application. (Combined with...) Figure 54 The roller brush 500f provided in this application includes two blades 505, both of which are rotatable to cut away any debris that may be entangled on the roller brush, thereby reducing the amount of debris on the roller brush surface, improving the cleanliness of the roller brush surface, and avoiding any impact on the operation of the roller brush, thus improving the cleaning effect of the cleaning equipment. The specific details of the roller brush 500f are now further described with reference to the accompanying drawings.

[0229] Figure 54 The roller brush 500f shown is a type of roller brush 500, similar to roller brush 500d. The main difference is that both blades 505 of roller brush 500f are rotatable, while one blade 505 of roller brush 500d is fixed and the other blade 505 rotates. Roller brush 500d also includes a brush body 501, a cleaning component 503, a cutting groove 504, and protective teeth 506. Unless otherwise specified, the structure and function of these components in roller brush 500f are largely the same as those in roller brush 500d, and therefore can be referred to the corresponding description of the roller brushes described above, which will not be repeated here.

[0230] Figure 55 for Figure 54 A schematic diagram of the radial cross-section. Combined with... Figure 55 The brush body 501 has a cutting groove 504 on its periphery, which communicates with the interior of the brush body 501. At least a portion of the cutting edges of the two blades 505 of the cutting assembly are disposed within the cutting groove 504 to cut the material wrapped around the brush body 501. In addition, the cutting groove 504 can be generally elongated to have a suitable size so that the blades 505 have a sufficient cutting range within the cutting groove 504, ensuring the cutting effect on the material wrapped around the brush body 501.

[0231] Combination Figure 55Two cutting grooves 504 are provided on the periphery of the brush body 501. The two cutting grooves 504 are arranged to be mutually connected. At least a portion of the cutting edges on the periphery of the two blades 505 of the cutting assembly protrudes from the two cutting grooves 504 to simultaneously cut the material wrapped around the brush body 501, thereby improving cutting efficiency. In another embodiment, each blade 505 may be equipped with only one cutting groove 504, and the material wrapped around the brush body 501 can also be cut by the cutting edges of the blades 505 protruding from the cutting grooves 504.

[0232] Combination Figure 55 The two blades 505 of the roller brush 500f can be defined as a first blade 5051 and a second blade 5052. Both the first blade 5051 and the second blade 5052 are placed inside the brush body 501 and can rotate relative to the brush body 501. At least part of the cutting edge on the periphery of the first blade 5051 and the second blade 5052 protrudes into the cutting groove 504, so as to cut the entanglement that may be wrapped on the roller brush by the two blades 505 that can rotate relative to the brush body 501, thereby reducing the entanglement on the roller brush surface, improving the cleanliness of the roller brush surface, so as to avoid affecting the operation of the roller brush and improve the cleaning effect of the cleaning equipment.

[0233] Combination Figure 55 The brush body 501 is provided with a receiving cavity 5013, which communicates with the cutting grooves 504 on both sides. The cutting assembly is placed inside the receiving cavity 5013. The middle parts of the two blades 505 of the cutting assembly are respectively connected to the support shafts 5054. The support shafts 5054 can be arranged along the axial direction perpendicular to the brush body 501. The two support shafts 5054 are arranged opposite to each other, and their opposite ends are inserted into each other so that the two support shafts 5054 can rotate independently. The opposite ends of the two support shafts 5054 are placed inside the receiving cavity 5013, and the back ends of the two support shafts 5054 pass through the side wall of the receiving cavity 5013 and are connected to the inner wall of the brush body 501.

[0234] Figure 56 for Figure 54 An internal diagram. Combined with... Figure 55 as well as Figure 54 In one embodiment, two first support members 5086 are provided inside the brush body 501. Each first support member 5086 can be a bearing or a copper sleeve. The opposite ends of two support shafts 5054 are rotatably connected to the two first support members 5086, allowing the support shafts 5054 to be rotatably disposed relative to the brush body 501. In another embodiment, two mounting grooves are provided on the inner wall of the brush body 501. The opposite ends of the two support shafts 5054 can also be rotatably connected to the two mounting grooves of the brush body 501.

[0235] Combination Figure 55 as well as Figure 56In one embodiment, the two blades 505 are fitted together to prevent the cut hair from entering the brush body 501 through the gap between the two blades 505, thus avoiding interference with the operation of the internal components of the brush body 501. In another embodiment, since the cleaning device's fan will suck away the cut hair during operation, a small gap may also exist between the two blades 505.

[0236] Combination Figure 55 as well as Figure 56 Under long-term use of cleaning equipment, since both blades 505 are rotatably mounted relative to the brush body 501 and are arranged in close contact, the first blade 5051 or / and the second blade 5052 will experience certain wear, which may lead to gaps between them. Based on this, the roller brush of this application also includes an elastic element 507. The elastic element 507 can compensate for the wear of the first blade 5051 or / and the second blade 5052, keeping the two blades 505 in close contact, so as to prevent the cut hair from entering the brush body 501 through the gap between the two blades 505, thus avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

[0237] Combination Figure 55 as well as Figure 56 In one embodiment, the aforementioned elastic element 507 is provided between the end faces of both blades 505 and the sidewall of the receiving cavity 5013 to compensate for wear on the first blade 5051 and / or the second blade 5052, keeping the two blades 505 in contact. In another embodiment, the aforementioned elastic element 507 may be provided only between the end face of one of the blades 505 and the sidewall of the receiving cavity 5013 to compensate for wear on the first blade 5051 and / or the second blade 5052, keeping the two blades 505 in contact.

[0238] Figure 57 for Figure 56 A schematic diagram of the elastic element 507 in the diagram. (Combined with...) Figure 57 The elastic member 507 is provided with a second limiting protrusion 5071 on its periphery. The second limiting protrusion 5071 abuts against the side wall of the receiving cavity 5013 so that the elastic member 507 can remain fixed when the blade body 505 rotates, and prevent the elastic member 507 from rotating with the blade body 505.

[0239] Figure 58 for Figure 56 A structural schematic diagram of the blade 505. (Combined with...) Figure 58In some embodiments, the first cutter body 5051 and / or the second cutter body 5052 are provided with a plurality of heat dissipation holes 5059. The heat dissipation holes 5059 can be circular or square or other shapes. On the one hand, they can dissipate heat when the first cutter body 5051 rotates relative to the second cutter body 5052. On the other hand, they can reduce the contact area between the two, reduce friction, make the first cutter body 5051 rotate smoothly relative to the second cutter body 5052, and improve the service life of both.

[0240] Combination Figure 56 The roller brush also includes a transmission assembly 508, which is placed inside the brush body 501 and connected to two blades 505 to drive the two blades 505 to rotate simultaneously relative to the brush body 501 to cut any entangled material that may be wrapped around the roller brush.

[0241] In one embodiment, the two blades 505 rotate relative to each other, so that the relative motion of the shearing teeth on the periphery of the two blades 505 cuts the material that may be wrapped around the roller brush, thereby improving the cutting effect on the wrapped material. In another embodiment, the two blades 505 may also rotate in the same direction at a different speed, that is, both blades 505 have the same rotational speed, but their rotational speeds have a speed difference, which can also cut the material that may be wrapped around the roller brush. Now, by way of the attached... Figure 59 -Appendix Figure 62 Further details of the transmission assembly 508 are described below.

[0242] Figure 59 for Figure 56 A top-down view diagram, combined with Figure 56 as well as Figure 59According to one embodiment of this application, the transmission assembly 508 includes a driving member 5081, a main gear 5083, a driven gear 5085, and a swing arm 5082. The driving member 5081 is provided with a rotatable driving part, the main gear 5083 is connected to the driving part, and two driven gears 5085 are provided, both of which are rotatably disposed within the brush body 501. At least one driven gear 5085 engages with the conical surface of the main gear 5083. A swing shaft 50819 is eccentrically mounted on the gear 5085. The swing arm 5082, driven gear 5085, cutter body 505 and support shaft 5054 are arranged in a corresponding manner. One end of the swing arm 5082 is provided with a connecting recess 50820, which is connected to the swing shaft 50819 of the corresponding driven gear 5085. The other end of the swing arm 5082 is connected to the support shaft 5054, and the cutter body 505 is connected to the corresponding support shaft 5054. When the drive component 5081 rotates, the driven gear 5085 can be driven to rotate within the brush body 501 through the conical engagement of the main gear 5083 and the driven gear 5085. The swing shaft 50819 on the driven gear 5085 rotates synchronously with the driven gear 5085. The swing shaft 50819 reciprocates within the connecting recess 50820 of the corresponding swing arm 5082 to drive the support shaft 5054 to rotate, thereby driving the two blades 505 to rotate relative to the brush body 501 to cut the entanglement that may be wrapped around the roller brush.

[0243] Combination Figure 56 as well as Figure 59 Two driven gears 5085 are connected to a connecting shaft 5055, which can be perpendicular to the central axis of the brush body 501. A fixing member 512 is fixedly placed inside the brush body 501. The middle part of the connecting shaft 5055 is placed in the fixing member 512, and both ends of the connecting shaft 5055 protrude from the fixing member 512. The two driven gears 5085 are respectively connected to the two ends of the connecting shaft 5055. The fixing member 512 can be a columnar structure or a square structure. When the fixing member 512 is a columnar structure, a positioning protrusion 5121 is provided on the periphery of the fixing member 512. The positioning protrusion 5121 is embedded in the inner wall of the brush body 501 so that the fixing member 512 is fixedly assembled inside the brush body 501 and prevents the fixing member 512 from being driven to rotate by the connecting shaft 5055.

[0244] In one embodiment, the connecting shaft 5055 is rotatably connected to the fixing member 512. Two driven gears 5085 are fixedly assembled at both ends of the connecting shaft 5055 by means of key connection or the like. When one driven gear 5085 is driven to rotate, the driven gear 5085 drives the connecting shaft 5055 to rotate in the fixing member 512, and then drives the other driven gear 5085 (which does not mesh with the main gear 5083) to rotate. In another embodiment, the connecting shaft 5055 is fixed to the fixing member 512 by means of key connection or the like. The driven gears 5085 are rotatably connected to the connecting shaft 5055. Both driven gears 5085 mesh with the main gear 5085. When the two driven gears 5085 are driven to rotate, the two driven gears 5085 rotate around the connecting shaft 5055.

[0245] Figure 60 for Figure 56 A schematic diagram of the swing arm 5082 in the diagram. (Combined with...) Figure 60 In one embodiment, the connecting recess 50820 on the swing arm 5082 can be an oblong hole, and the swing shaft 50819 can slide along its length in the oblong hole to drive the support shaft 5054 at the other end of the swing arm 5082 to rotate. In another embodiment, the connecting recess 50820 on the swing arm 5082 can also be an oblong groove, and the swing shaft 50819 can slide along its length in the oblong groove to drive the support shaft 5054 at the other end of the swing arm 5082 to rotate.

[0246] Combination Figure 60 The overall shape of the swing arm 5082 can be Z-shaped to accommodate the internal space of the brush body 501. The other end of the swing arm 5082 can be fixedly connected to the corresponding support shaft 5054 by means of key connection or other means. The other end of the swing arm 5082 is placed between the first support member 5086 and the corresponding blade body 505. A partition is provided between the swing arm 5082 and the corresponding blade body 505. The partition is gap-connected to the support shaft 5054. The partition can be a wave-shaped gasket, which can axially separate the corresponding blade body 505 and the swing arm 5082 on the support shaft 5054 to avoid interference between the two. It also makes the contact between the partition and the blade body 505 and the swing arm 5082 a partial contact to reduce the friction area between the partition and the blade body 505 and the swing arm 5082, so that the blade body 505 and the swing arm 5082 can rotate smoothly.

[0247] Combining 56 and Figure 59The drive unit 5081 includes a power input shaft 5084, a reduction mechanism 5088, and a power output shaft 5089 connected in sequence, wherein the power output shaft 5089 is configured as the drive unit. When the power input shaft 5084 rotates, the reduction mechanism 5088 reduces the rotational speed of the power output shaft 5089, thereby allowing the two blades 505 to rotate at a suitable speed. This reduces the noise of the cleaning equipment and minimizes wear on the two blades 505, demonstrating excellent practicality.

[0248] Combining 56 and Figure 59 One end of the power input shaft 5084 can be connected to the support seat 502 at the other end of the brush body 501. When the roller brush moves and rolls on the ground, the power input shaft 5084 rotates relative to the brush body 501, thereby driving the power output shaft 5089 and the cooperating main gear 5083 and driven gear 5085 to rotate, so as to drive the two blades 505 to rotate and cut the entanglement that may be wrapped on the roller brush.

[0249] Combining 56 and Figure 59 One or more second support members 514 can be provided inside the brush body 501. The power input shaft 5084 rotatably passes through the second support member 514 to support the power input / output shaft. The second support member 514 can be a bearing or a copper sleeve to ensure that the power input shaft 5084 can rotate stably within the second support member 514. In specific implementations, the number of second support members 514 can be set according to the length of the power input shaft 5084. If the power input shaft 5084 is long, multiple second support members 514 can be provided; if the power input shaft 5084 is short, only one second support member 514 can be provided. Similarly, an appropriate number of second support members 514 can also be configured on the power input shaft 5084.

[0250] The reduction mechanism 5088 in the roller brush 500f can reduce the speed of the power output shaft 5089 to a suitable range, and also reduce the speed of the driven gear 5085 and the first cutter body 5051, thereby reducing noise and wear on the first cutter body 5051 and the second cutter body 5052. In specific implementation, the reduction mechanism 5088 in the roller brush 500f can be the same as the reduction mechanism 5088 in the roller brush 500b, that is, the reduction mechanism 5088 can be a planetary gear reducer. Planetary gear reducers are characterized by small size, high load capacity, and stable operation, and can adapt to the internal space of the brush body 501501, and ensure stable power output. The planetary gear reducer can have one or more transmission stages. The more stages, the larger the reduction ratio. The number of stages can be set according to the reduction requirements.

[0251] Combination Figure 61In one embodiment, along the axial direction of the connecting shaft 5055, the projections of the swing shafts 50819 on the two driven gears 5085 are located at different positions on the same circumference, which is coaxial with the connecting shaft 5055. That is, the distance between the swing shafts 50819 on the two driven gears 5085 and the central axis of the driven gear 5085 is the same, but the line connecting the two intersects the connecting shaft 5055, so that the two cutter bodies 505 driven by the two transmission gears rotate relative to each other to cut the material that may be wrapped around the roller brush, thereby improving the cutting effect on the wrapped material. In specific implementation, the central angle formed by the projections of the swing shafts 50819 on the two driven gears 5085 can be between 90° and 180° to ensure that the two cutter bodies 505 can rotate relative to each other. For example, the projections of the swing shafts 50819 on the two driven gears 5085 can be symmetrically arranged on both sides of the circumference, or the central angle formed by the projections of the swing shafts 50819 on the two driven gears 5085 can be 90°, 135°, etc., without any restrictions.

[0252] Combination Figure 62 In another embodiment, along the axial direction of the connecting shaft 5055, the projections of the swing shafts 50819 on the two driven gears 5085 are located on two circumferences, that is, the distances between the swing shafts 50819 on the two driven gears 5085 and the connecting shaft 5055 are not consistent. Under the condition that the two driven gears 5085 rotate, the rotation of the corresponding two cutter bodies 505 can have a speed difference to cut the entangled material that may be wrapped around the roller brush. In specific implementation, if the central angle formed by the projections of the swing shafts 50819 on the two driven gears 5085 is between 0 and 45 degrees, the two cutter bodies 505 rotate in the same direction at a different speed; if the central angle formed by the projections of the swing shafts 50819 on the two driven gears 5085 is between 135 and 180 degrees, the two cutter bodies 505 rotate in opposite directions at a different speed.

[0253] In summary, the roller brush provided in this application can cut away any entangled material that may be wrapped around the roller brush through two mutually rotating blades, reducing the entangled material on the roller brush surface, improving the cleanliness of the roller brush surface, thereby reducing the resistance of the roller brush operation to avoid affecting the operation of the roller brush. At the same time, it also improves the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment, and has good practicality.

[0255] Cleaning equipment equipped with any of the aforementioned roller brushes reduces the amount of debris entangled on the brush surface, improving its cleanliness and thus lowering the resistance during operation. This prevents the brush from being affected and also increases its cleaning efficiency, thereby enhancing the overall cleaning effect and making the equipment highly practical. The cleaning equipment can be a robotic vacuum cleaner, floor scrubber, or mop, among other things.
