[0053] In order for those skilled in the art to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0054] With the development of science and technology, cleaning equipment has become more and more popular. The floor cleaning work in families and offices has been gradually replaced by cleaning equipment.

[0055] Now, specific technical solutions will be described in detail with reference to the accompanying drawings which are not necessarily drawn to scale. Similar or identical reference numerals can be used to designate similar or identical parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all drawings including the similar or identical reference numerals constitute a single or same embodiment. The accompanying drawings generally illustrate various embodiments discussed in the present application in an exemplary and non-limiting manner.

[0056] FIG. 1 The structural schematic diagram of the dirt collecting assembly 10 described in an embodiment of the present application, FIG. 2 For FIG. 1 The air path schematic diagram of the dirt collecting assembly 10. In combination with FIG. 1 And FIG. 2 The dirt collecting assembly 10 includes a driving device 400, a rolling brush 500, a fan 100, a dirt guide cover 300 and a dust box (also referred to as a dirt collecting member) 200. During the operation of the cleaning equipment, the driving device 400 drives the rolling brush 500 to run on the surface to be cleaned, so as to gather the dirt on the surface to be cleaned. At this time, the fan 100 is in an operating state, so as to suck the dirt gathered by the rolling brush 500 through the dirt guide cover 300 into the dust box 200, thereby automatically completing the cleaning work on the surface to be cleaned. It should be noted that, FIG. 1 And FIG. 2 Only for the convenience of the reader to understand, the installation and possible application environment of a rolling brush 500 are illustrated. It can be understood that the rolling brush 500 can be installed or applied in other dirt collecting assemblies or cleaning equipment, and the corresponding cleaning effect can also be achieved.

[0057] Since the dirt on the surface to be cleaned can be a winding object such as hair, when the rolling brush 500 performs the cleaning action, the winding object such as hair is easily wound on the rolling brush 500 along with the rotation of the rolling brush 500. Too much winding object wound on the rolling brush 500 can cause the rolling brush 500 to rub against the surface to be cleaned, emit an abnormal sound, even cause deformation (for example, the rolling brush 500 is a rubber brush), and affect the cleaning effect.

[0058] To solve the above technical problems, the rolling brush 500 provided by the present application comprises at least one knife body which can move relative to the brush body under the drive of the transmission member, so as to cut the winding object wound on the surface of the rolling brush 500, avoid the rolling brush 500 from making abnormal sound, deforming or affecting the operation of the rolling brush 500 itself or even the cleaning equipment on which the rolling brush 500 is installed, and improve the cleaning effect of the cleaning equipment. The following will be described in detail in combination with the drawings. FIG. 3 to FIG. 43 The rolling brush 500 provided by the present application will be described in detail.

[0059] FIG. 3 The structure schematic diagram of the rolling brush 500a provided by an embodiment of the present application, the rolling brush 500a is one of the rolling brush 500. As shown in the figure, FIG. 3 the rolling brush 500a comprises at least one cutting assembly, each cutting assembly comprises at least one rotating knife body which can cut the winding object wound on the rolling brush, so as to reduce the winding object on the surface of the rolling brush, improve the cleanliness of the surface of the rolling brush, avoid affecting the operation of the rolling brush, and improve the cleaning effect of the cleaning equipment. The specific details of the rolling brush 500a will be further described in the following. FIG. 14 - the specific details of the rolling brush 500a will be further described in the following. FIG. 19

[0060] The rolling brush 500a comprises at least two knife bodies 505 which move relative to each other, so as to cut the winding object wound on the rolling brush 500a, improve the operation efficiency of the rolling brush 500a and the cleaning effect of the cleaning equipment on which the rolling brush 500a is installed.

[0061] As shown in the figure, FIG. 3 in addition to the knife body 505, the rolling brush 500a further comprises a brush body 501 which is a hollow column structure, so as to constitute the main body of the whole rolling brush 500a and serve as the installation basis of the remaining components of the rolling brush 500a. One end of the brush body 501 is configured to be connected with the driving device 400 of the cleaning equipment, so that the brush body 501 can roll on the surface to be cleaned under the drive of the driving device 400, so as to gather the dirt attached to the surface to be cleaned.

[0062] Specifically, as shown in the figure, FIG. 3 one end of the brush body 501 in the axial direction is provided with a connecting part 5011, the brush body 501 is connected to the driving device 400 of the cleaning equipment through the connecting part 5011, so that the brush body 501 can roll on the surface to be cleaned under the drive of the driving device 400, so as to gather the dirt attached to the surface to be cleaned. In addition, as shown in the figure, FIG. 3 the other end of the brush body 501 in the axial direction is provided with a support seat 502, the other end of the brush body 501 in the axial direction is rotatably connected in the support seat 502 through a bearing or the like, and the support seat 502 is fixedly arranged on the cleaning equipment. When the cleaning equipment operates, the brush body 501 rotates relative to the support seat 502.

[0063] In addition, as shown in the figure, FIG. 3 ​As shown, the rolling brush 500a further comprises a cleaning member 503 which is integrally formed or fixedly connected to the circumferential side of the brush body 501. The cleaning member 503 has a certain elasticity so as to contact the surface to be cleaned during the rotation of the rolling brush 500a and roll up the dirt on the surface to be cleaned.

[0064] As shown in the drawings, FIG. 3 The cleaning member 503 comprises at least one cleaning strip 5031. When the number of the cleaning strips 5031 is greater than one, the cleaning strips 5031 can be arranged at intervals on the circumferential surface of the brush body 501, that is, the adjacent cleaning strips have a certain interval. In addition, the at least one cleaning strip 5031 can extend between the axial ends of the brush body 501 along the axial direction of the brush body 501; the at least one cleaning strip 5031 can also extend between the axial ends of the brush body 501 along a direction having an angle with the axial direction of the brush body 501; or the at least one cleaning strip 5031 can also extend between the axial ends of the brush body 501 along an arc, a spiral or other regular or irregular curve. In addition, the shapes of any two of the at least one cleaning strip 5031 can be the same or different. The number, extension direction and whether the two ends abut against the axial ends of the brush body 501 of the cleaning strip 5031 are not limited in the present application, so that the linear entanglements such as hair can move to or be supported at the cutter body 505 along the at least one cleaning strip 5031 during the rolling of the rolling brush 500a on the surface to be cleaned. However, in order to make the reader clear about the possible structure and function of the cleaning strip 5031, the following will be described in detail by taking FIG. 4 one of the at least one cleaning strip 5031 as an example.

[0065] As shown in the drawings, FIG. 3 The cleaning member 503 further comprises at least one row of bristles 5033 arranged 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 rolling brush 500a on the carpet or other surface to be cleaned and prevent the entanglements such as hair from being blocked by the bristles 5033 during the rotation of the rolling brush 500a. It should be noted that the rolling brush 500a provided in the present application can only comprise the at least one cleaning strip 5031 or only comprise the at least one row of bristles 5033, or can comprise both the at least one cleaning strip 5031 and the at least one row of bristles 5033.

[0066] FIG. 4 The schematic view of the cleaning strip 5032 described in an embodiment of the present application is one of the at least one cleaning strip 5031. As shown in the drawings, FIG. 4As shown, the inner side of the cleaning strip 5032 is fixed or integrally formed or implanted on one side of the brush body 501, 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, so also referred to as the edge side 50322 of the cleaning strip 5032. In FIG. 4 In the embodiment shown, the cleaning strip 5032 is folded by providing a folding rib 50323 from the inner side 50321 to the outer side 50322, wherein the length L of the folding rib 50323 is the shortest distance from the inner edge 50321 to the outer edge 50322 along the surface of the cleaning strip 5032, so that the winding can be guided to the working area of the cutter body 505. As shown, FIG. 4 In the embodiment shown, the folding rib 50323 is provided in the middle of the cleaning strip 5032, but it can be understood that the folding rib 50323 can also be provided at other positions of the cleaning strip 5032 to guide the winding to the working area of the cutter body 505.

[0067] In addition, as shown, FIG. 4 The inner edge 50321 of the cleaning strip 5032 is arranged in a V shape or a U shape, so that the outer edge 50322 of the cleaning strip 5032 is correspondingly arranged in a V shape or a U shape, and has a better effect of gathering dirt. That is, the cleaning strip 5032 presents two cleaning sections with opposite rotation directions, and during the rolling of the roller brush 500a on the ground, the hair and other windings will move along the spiral cleaning strip 5031 and be gathered to the gap between the two cleaning sections with the rotation of the roller brush 500a, and correspondingly, the working area of the cutter body 505 can be arranged between the two cleaning sections. In specific implementation, one end of the two cleaning sections close to each other can be connected together by the folding rib 50323 to guide the winding contacting the two cleaning sections to the working area of the cutter body 505. And it can be understood by those skilled in the art that the inner edge of the cleaning strip 5032 can also be a straight strip, a spiral or other curved shape, and correspondingly, the outer edge of the cleaning strip 5032 can also be a straight strip, a spiral or other curved shape.

[0068] In another embodiment, FIG. 4 As shown, the two cleaning sections can also not be connected, so that the hair and other windings can be directly gathered to the gap between the two cleaning sections along the streamline design of the two cleaning sections, that is, the working area of the cutter body 505.

[0069] In another embodiment, the cleaning strip 5032 can be at least partially linear, diagonal or / and arc-shaped, and each cleaning strip 5031 can also include the above-mentioned two cleaning sections 5032, and the shapes of the two cleaning sections 5032 can be consistent or inconsistent, and during the rolling of the roller brush 500a on the ground, the hair and other windings can also move along the arrangement direction of the cleaning strip 5031 with the rotation of the roller brush 500a.

[0070] In another embodiment, FIG. 4 The cleaning strip 5032 shown can also be designed as a streamlined whole, without needing to have FIG. 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.

[0071] In another embodiment, FIG. 4 The cleaning strip 5032 shown can also be a single, integrated design, without the need for... FIG. 3 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.

[0072] Combination FIG. 6 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... FIG. 5 The specific shape of the cutting groove 504 and how the cutting groove 504 houses the cutter body 505 are described in detail.

Since the first cutter body 5051 is rotatably arranged in the brush body 501 and the second cutter body 5052 is fixedly arranged in the brush body 501, the first cutter body 5051 is rotatably arranged relative to the second cutter body 5052, the fixed hair and the like are cut by the second cutter body 5052 fixedly arranged, and the fixed hair and the like are cut by the second cutter body 5052 rotatably arranged relative to the first cutter body 5051, thereby improving the shearing effect on the hair and the like.

[0092] Figure 8 is a schematic view of the assembly of the cutting assembly in the brush body 501. FIG. 11 In an embodiment, the first cutter body 5051 is arranged between the second cutter body 5052 and the driven gear 5085 to reasonably utilize the internal space of the brush body 501. In another embodiment, the second cutter body 5052 is arranged between the first cutter body 5051 and the driven gear 5085, which is not limited in the present application.

[0093] Figure 8 is a schematic view of the assembly of the cutting assembly in the brush body 501. FIG. 12 In an embodiment, the first cutter body 5051 and the second cutter body 5052 are arranged in close contact to avoid the cut hair entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052, thereby avoiding the phenomenon of affecting the operation of the internal components of the brush body 501.

FIG. 12 Figure 12 is a schematic view of the assembly of the cutting assembly in the brush body 501. FIG. 13 Figure 13 is a schematic view of the assembly of the cutting assembly in the brush body 501. FIG. 11-FIG. 13A plurality of heat dissipation holes 5059 are arranged on the first cutter body 5051 and / or the second cutter body 5052. The heat dissipation holes 5059 can be circular or square in shape. On one hand, the heat dissipation holes 5059 can dissipate heat when the first cutter body 5051 rotates relative to the second cutter body 5052. On the other hand, the heat dissipation holes 5059 can also reduce the contact area between the first cutter body 5051 and the second cutter body 5052, thereby reducing the friction and making the first cutter body 5051 rotate smoothly relative to the second cutter body 5052. In addition, the heat dissipation holes 5059 can also prolong the service life of the first cutter body 5051 and the second cutter body 5052.

[0095] In combination FIG. 11-FIG. 13 The brush body 501 is provided with a receiving cavity 5013. The cutting groove 504 and the receiving cavity 5013 are communicated with each other. The second cutter body 5052 is fixedly arranged in the receiving cavity 5013. The first cutter body 5051 is rotatably arranged in the receiving cavity 5013. At least one of the outer sides of the first cutter body 5051 and the second cutter body 5052 and the receiving cavity 5013 are provided with an elastic member 507. Under the condition of long-term use of the cleaning device, since the first cutter body 5051 rotates relative to the second cutter body 5052 and the two are arranged in close contact, the first cutter body 5051 and / or the second cutter body 5052 will be worn to a certain extent, which may cause a gap between the two. Based on this, the elastic member 507 can compensate for the wear of the first cutter body 5051 and / or the second cutter body 5052, so that the first cutter body 5051 and the second cutter body 5052 remain in close contact. In this way, the cut hair can be prevented from entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052, thereby avoiding the phenomenon that the operation of the internal components of the brush body 501 is affected.

The accommodating cavity 5013 further comprises a second accommodating cavity 50132, the second accommodating cavity 50132 is communicated with the first accommodating cavity 50131, the thickness of the second accommodating cavity 50132 is slightly greater than the thickness of the first cutter body 5051, the first cutter body 5051 is rotatably assembled in the first accommodating cavity 50131, the elastic member 507 is arranged between the side of the first cutter body 5051 away from the second cutter body 5052 and the sidewall of the second accommodating cavity 50132, under the condition that the first cutter body 5051 or / and the second cutter body 5052 is worn, the elastic member 507 can compensate the wear of the first cutter body 5051 or / and the second cutter body 5052, so that the first cutter body 5051 and the second cutter body 5052 can be kept in close contact. In another embodiment, the thickness of the first accommodating cavity 50131 can also be slightly greater than the thickness of the second cutter body 5052, the second cutter body 5052 can be slightly moved in the first accommodating cavity 50131, an elastic member 507 is arranged between the side of the second cutter body 5052 away from the first cutter body 5051 and the sidewall of the first accommodating cavity 50131, or, an elastic member 507 is arranged between the side of the second cutter body 5052 away from the first cutter body 5051 and the sidewall of the first accommodating cavity 50131, and between the side of the first cutter body 5051 away from the second cutter body 5052 and the sidewall of the second accommodating cavity 50132, so as to compensate the wear of the first cutter body 5051 or / and the second cutter body 5052, and keep the first cutter body 5051 and the second cutter body 5052 in close contact.

In combination with FIG. 15 , the elastic member 507 is generally in a circular structure, the circumferential side of the elastic member 507 is provided with a second limiting protrusion 5071, two second limiting protrusions 5071 can be provided oppositely, so as to abut against the inner wall of the second accommodating cavity 50132, so that the elastic member 507 can be fixedly arranged in the toothbrush body 501.

[0098] FIG. 16 is the assembly diagram of the first cutter body 5051 and the driven gear 5085, FIG. 15 is the structure diagram of the partition member 513. In combination with FIG. 16 and FIG. 17A partition member 513 is arranged between the first cutter body 5051 and the driven gear 5085. The partition member 513 is arranged in the middle of the elastic member 507 in a gap. The partition member 513 can be a wave-shaped gasket. The partition member 513 can axially separate the first cutter body 5051 and the driven gear 5085 to avoid interference between the first cutter body 5051 and the driven gear 5085. The partition member 513 is in partial contact with the first cutter body 5051 and the driven gear 5085 to reduce the friction area between the partition member 513 and the first cutter body 5051 and the driven gear 5085, so that the first cutter body 5051 and the driven gear 5085 can rotate smoothly.

[0099] In another embodiment, the first cutter body 5051 can 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, so that the entanglements on the rolling brush can be cut.

[0100] FIG. 16 For FIG. 17 the structure of the driving member 5081. In combination with FIG. 17 , the driving member 5081 includes a power input shaft 5087, a speed reduction mechanism 5088 and a power output shaft 5089 connected in sequence. The power output shaft 5089 is configured as a driving part. The power input shaft 5087 is arranged in the brush body 501 and intersects with the central shaft of the driving shaft 5084. The power input shaft 5087 is connected to the power output shaft 5089 through the speed reduction mechanism 5088, so that the rotating speed of the power output shaft 5089 can be reduced to an appropriate range, and the rotating speed of the driven gear 5085 and the first cutter body 5051 is also reduced, so that the noise is reduced and the abrasion of the first cutter body 5051 and the second cutter body 5052 is reduced.

[0101] In combination with FIG. 18 , 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 rolling brush rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501 to transmit power to the main gear 5083 through the speed 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.

[0102] In combination with FIG. 19One 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.

[0103] 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.

[0104] 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. 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. (See attached diagram.) FIG. 18 -Appendix FIG. 18 The structure of the planetary gear reducer is further explained.

[0105] FIG. 19 This is a structural schematic diagram of the 5088 reduction mechanism. (Combined with...) FIG. 18 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.

[0106] FIG. 19 for FIG. 19 The diagram shown is of the internal structure of the deceleration mechanism 5088. FIG. 20The reduction mechanism 5088 comprises a first central wheel 50883, a first planetary wheel 50884 and a first planetary carrier 50885. The first planetary carrier 50885 is arranged in the shell 50881 and spaced from the axial end of the shell 50881. The central shaft of the first central wheel 50883 is connected with the power input shaft 5087 and extends through the axial end of the shell 50881. The other end of the central shaft of the first central wheel 50883 is rotatably connected in the first planetary carrier 50885. The first planetary wheels 50884 are arranged in the circumferential side of the first central wheel 50883. The central shaft of the first planetary wheels 50884 is intermittently abutted against the axial end of the shell 50881. The other end of the central shaft of the first planetary wheels 50884 is connected with the first planetary carrier 50885. The first planetary carrier 50885 is connected with the power output shaft 5089. Under the condition that the power input shaft 5087 is rotated, the first central wheel 50883 and the power input shaft 5087 are synchronously rotated to drive the first planetary wheels 50884 to revolve around the first central wheel 50883 and drive the first planetary carrier 50885 to rotate around the central shaft of the first central wheel 50883, thereby transmitting power to the power output shaft 5089 to form a first reduction.

[0107] In combination FIG. 20 The reduction mechanism 5088 further comprises a second central wheel 50886, a second planetary wheel 50887 and a second planetary carrier 50888. The second planetary carrier 50888 is arranged in the shell 50881 and spaced from the other axial end of the shell 50881. The input end of the central shaft of the second central wheel 50886 is fixedly connected with the middle portion of the first planetary carrier 50885. The other end of the central shaft of the second central wheel 50886 is rotatably connected in the second planetary carrier 50888. The second planetary wheels 50887 are arranged in the circumferential side of the second central wheel 50886. The central shaft of the second planetary wheels 50887 is intermittently abutted against the first planetary carrier 50885. The other end of the central shaft of the second planetary wheels 50887 is connected with the second planetary carrier 50888. The second planetary carrier 50888 is connected with the power output shaft 5089. Under the condition that the first planetary carrier 50885 rotates around the central shaft of the central wheel, the second central wheel 50886 is driven to rotate, thereby driving the second planetary wheels 50887 to revolve around the second central wheel 50886 and driving the second planetary carrier 50888 to rotate around the central shaft of the second central wheel 50886, thereby transmitting power to the power output shaft 5089 to form a second reduction.

[0108] 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.

[0109] In summary, the roller brush 500a 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, thereby reducing the tangled material on the roller brush surface, improving the cleanliness of the roller brush surface, reducing the resistance of the roller brush operation, so as to avoid affecting the operation of the roller brush, and at the same time improving the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment, and has good practicality.

[0110] FIG. 20 This is a schematic diagram of another type of roller brush 500b according to this application. (Combined with...) FIG. 27 This application provides a roller brush 500b, 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 brush surface and improving its cleanliness. This avoids affecting the operation of the roller brush and improves the cleaning effect of the cleaning equipment. (See attached document.) FIG. 20 -Appendix FIG. 21 Further details regarding the 500b roller brush are described below.

[0111] FIG. 20 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 a protective tooth 506. Unless otherwise specified, the structure and function of these components in roller brush 500a are roughly the same as those in the roller brush described above. Therefore, the corresponding description of the roller brush described above can be referred to, and will not be repeated here.

FIG. 22 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.

[0113] Combination FIG. 20In an embodiment, the brush body 501 is provided with two cutting grooves 504, and the two cutting grooves 504 are oppositely arranged. At least part of the cutting edges on the circumferential sides of the two cutter bodies 505 protrude from the two cutting grooves 504, so as to simultaneously cut the winding material wound on the brush body 501, and improve the cutting efficiency.

At least part of the cutting edges on the circumferential sides of the first cutter body 5051 and the second cutter body 5052 protrude from the cutting groove 504, so as to cut the winding material possibly wound on the rolling brush, and then reduce the winding material on the surface of the rolling brush, improve the cleanliness of the surface of the rolling brush, avoid affecting the operation of the rolling brush, and improve the cleaning effect of the cleaning equipment. At the same time, since the second cutter body 5052 reciprocates instead of rotating in the same direction all the time, the cut winding material can be prevented from entering between the two cutter bodies 505 and the brush body 501 along with the rotating cutter body 505, so as to avoid affecting the operation of the cutter body 505 and the internal components of the brush body 501.

[0116] In combination with FIG. 20The brush body 501 is provided with a containing cavity 5013 which is communicated with the cutting grooves 504 on both sides, and the cutting assembly is arranged in the containing cavity 5013. The brush body 501 is provided with a supporting shaft 5054 which is arranged along the axial direction perpendicular to the brush body 501, the middle part of the supporting shaft 5054 is arranged in the containing cavity 5013, and the two ends of the supporting shaft 5054 pass through the side wall of the containing cavity 5013 and are connected to the inner wall of the brush body 501. In an embodiment, two first supporting members 5086 are arranged in the brush body 501, the first supporting member 5086 can be a bearing or a copper sleeve, and the two ends of the supporting shaft 5054 are rotatably connected to the two first supporting members 5086 respectively, so that the supporting shaft 5054 can be rotatably arranged relative to the brush body 501. The first cutter body 5051 is gap-set on the supporting shaft 5054, and the second cutter body 5052 can be fixedly connected or gap-set on the supporting shaft 5054, so that the second cutter body 5052 rotates synchronously with the supporting shaft 5054, or the second cutter body 5052 rotates around the supporting shaft 5054. In another embodiment, the two ends of the supporting shaft 5054 can be fixedly connected to the inner wall of the brush body 501, so that the supporting shaft 5054 is fixedly connected to the brush body 501, the first cutter body 5051 is gap-set or fixedly connected on the supporting shaft 5054, and the second cutter body 5052 is gap-set on the supporting shaft 5054, so that the second cutter body 5052 is rotatably connected to the fixed supporting shaft 5054, and the second cutter body 5052 rotates around the supporting shaft 5054.

[0119] FIG. 26 The assembly of the cutting assembly in the brush body 501 is shown in the figure. In an embodiment, the first cutter body 5051 and the second cutter body 5052 are arranged in close contact to avoid the cut hair entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052, which may affect the operation of the internal components of the brush body 501. In another embodiment, since the air blower of the cleaning device can suck the cut hair away when the cleaning device is in operation, the first cutter body 5051 and the second cutter body 5052 can also have a small gap.

[0120] In combination FIG. 27 Under the condition of long-term use of the cleaning device, since the second cutter body 5052 reciprocates relative to the first cutter body 5051 and the two are arranged in close contact, the first cutter body 5051 or / and the second cutter body 5052 will be worn to some extent, which may cause a gap between the two. Based on this, the application is provided with an elastic member 507 between the outside of at least one of the first cutter body 5051 and the second cutter body 5052 and the accommodating cavity 5013. The elastic member 507 can compensate for the wear of the first cutter body 5051 or / and the second cutter body 5052, so that the first cutter body 5051 and the second cutter body 5052 remain in close contact to avoid the cut hair entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052, which may affect the operation of the internal components of the brush body 501.

The two ends of the swing arm 5082 are rotatably connected to the first driving shaft 50810 and the second driving shaft 50811 respectively. Under the condition that the driving member 5081 rotates, the swing arm 5082 is driven to reciprocate through the two eccentric driving shafts.

[0124] In combination with FIG. 27In an embodiment, the driving member 5081 comprises a power input shaft 5087, a worm gear mechanism 50812 and a first transmission wheel 50813, wherein the power input shaft 5087 is arranged in the brush body 501, the worm of the worm gear mechanism 50812 is connected to the power input shaft 5087, the worm wheel is rotatably connected in the brush body 501, the first transmission wheel 50813 is rotatably connected in the brush body 501 and in transmission connection with the worm wheel, the first transmission wheel 50813 is configured as a driving part, and the first driving shaft 50810 is connected to the end face of the first transmission wheel 50813. Under the condition that the power input shaft 5087 rotates, the first transmission wheel 50813 is driven to rotate by the transmission of the worm gear mechanism 50812, so as to drive the second cutter body 5052 to reciprocate by the swing arm 5082.

[0125] In combination FIG. 27 , one end of the power input shaft 5087 can be connected in the support seat 502 at the other end of the axial direction of the brush body 501, and when the rolling brush travels on the ground, the power input shaft 5087 rotates relative to the brush body 501 to drive the worm gear mechanism 50812, the first transmission wheel 50813 and the swing arm 5082 to act, and then drive the second cutter body 5052 to reciprocate.

[0126] In combination FIG. 27 , one or more than one first and second support members 514 can be arranged in the brush body 501, and the power input shaft 5087 can rotatably pass through the second support member 514 to support the power input shaft 5087 by the second support member 514. The second support member 514 can be a bearing or a copper bushing, so that the power input shaft 5087 can stably rotate in the second support member 514. In specific implementation, the number of the second support member 514 can be arranged according to the length of the power input shaft 5087. If the length of the power input shaft 5087 is relatively long, a plurality of second support members 514 can be arranged, and if the length of the transmission shaft is relatively short, only one second support member 514 can be arranged.

[0127] In combination FIG. 27 , the power input shaft 5087 is arranged along the axial direction of the brush body 501, and the central shaft of the first transmission wheel 50813 is perpendicular to the axial direction of the brush body 501, that is, the central shaft of the first transmission wheel 50813 is arranged perpendicularly to the power input shaft 5087. The power of the power input shaft 5087 can be transmitted to the first transmission wheel 50813 by the mediation of the worm gear mechanism 50812 to drive the first transmission wheel 50813 to rotate. The worm gear mechanism 50812 has the characteristics of stable work, small impact, vibration and noise, and can adapt to the assembly of the narrow space inside the brush body 501.

The transfer gear 50814 is arranged for the following reason: since the worm gear and the first transmission gear 50813 are not in the same plane, in order to realize power transmission between the worm gear and the first transmission gear 50813, power can be transmitted to the first transmission gear 50813 through the transfer gear 50814 which is in the same plane with the first transmission gear 50813. In another embodiment, if the worm gear and the first transmission gear 50813 are in the same plane, the worm gear can also directly engage with the first transmission gear 50813 for transmission, and the above-mentioned transfer gear 50814 can be cancelled.

The second transmission gear 50815 is arranged upstream of the first transmission gear 50813, and the radius of the second transmission gear 50815 is smaller than that of the first transmission gear 50813. The arrangement of the second transmission gear 50815 can adapt to the internal space of the brush body 501, and the second transmission gear 50815 and the first transmission gear 50813 are configured as a speed reduction mechanism to reduce the rotation speed of the first transmission gear 50813, and accordingly the speed of the reciprocating swing of the second cutter body 5052 is reduced, so as to reduce noise and wear of the first cutter body 5051 and the second cutter body 5052, which has good practicability. In another embodiment, if the internal space of the brush body 501 allows, the first transmission gear 50813 can directly engage with the transfer gear 50814 for transmission.

[0130] In combination FIG. 28 The first transmission gear 50813 can be fixedly connected to the first driving shaft 50810 by means of key connection or the like. The two ends of the first driving shaft 50810 are rotatably connected in the brush body 501, and one end of the swing arm 5082 is eccentrically connected to the first driving shaft 50810. Under the condition that the first transmission gear 50813 is driven to rotate, the first driving shaft 50810 is synchronously rotated to drive the swing arm 5082 to move. In order to make the rotation of the first driving shaft 50810 smooth, two third supporting members 515 are arranged in the brush body 501, and the two ends of the first driving shaft 50810 are rotatably connected in the two third supporting members 515. The third supporting member 515 can be a bearing or a copper bushing.

[0131] In combination FIG. 28In 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.

[0132] In summary, the roller brush 500b provided in this application, through the cooperation of a fixed 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.

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.

FIG. 33 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.

[0140] Combination FIG. 34 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.

[0141] Combination FIG. 34The elastic member 507 is arranged between the second cutter body 5052 and the brush body 501, and is arranged on the side of the second cutter body 5052 away from the first cutter body 5051, so as to compensate for the wear of the first cutter body 5051 or / and the second cutter body 5052, and keep the first cutter body 5051 and the second cutter body 5052 in close contact.

In specific implementation, the number of the second support member 514 can be arranged according to the length of the power input shaft 5084. If the length of the power input shaft 5084 is relatively long, a plurality of second support members 514 can be arranged.

In specific implementation, if the central angle of the circle formed by the projections of the swing axes 50819 on the two driven gears 5085 is between 0-45°, the two cutter bodies 505 rotate in the same direction at different speeds; if the central angle of the circle formed by the projections of the swing axes 50819 on the two driven gears 5085 is between 135-180°, the two cutter bodies 505 rotate in opposite directions at different speeds.
