[0022] ​​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 protection of the present application.

[0023] With the development of science and technology, cleaning equipment has become more and more popular. The floor cleaning work in units such as families and offices has been gradually replaced by cleaning equipment.

[0024] 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 the same or similar 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.

[0025] Figure 1 The structural schematic diagram of the dirt collecting assembly 10 described in an embodiment of the present application, Figure 2 For Figure 1 The wind path schematic diagram of the dirt collecting assembly 10. In combination with Figure 1 And Figure 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 to gather the dirt on the surface to be cleaned. At this time, the fan 100 is in an operating state 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, Figure 1 And Figure 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.

[0026] Since the dirt on the surface to be cleaned can be hair and the like, when the rolling brush 500 performs the cleaning action, the hair and the like can easily be entangled on the rolling brush 500 with the rotation of the rolling brush 500. If too much entangled matter is entangled on the rolling brush 500, the rolling brush 500 can rub against the surface to be cleaned, making an abnormal sound, even deforming (for example, the rolling brush 500 is a rubber brush), and affecting the cleaning effect.

[0027] To solve the above technical problems, the rolling brush 500 provided by the present application comprises at least one knife body capable of moving relative to the brush body under the driving of the transmission assembly, 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 the cleaning equipment on which the rolling brush 500 is installed, and improve the cleaning effect of the cleaning equipment. The rolling brush 500 provided by the embodiments of the present application will be described in detail below. Figures 3 to 13 The rolling brush 500 provided by the embodiments of the present application will be described in detail below.

[0028] Figure 3 The structure schematic diagram of the rolling brush 500 provided by an embodiment of the present application is shown in FIG. 1. As shown in the figure, the rolling brush 500 comprises at least two pieces of knife bodies 505 capable of moving reciprocally, so as to cut the winding object wound on the surface of the rolling brush 500, improve the operation efficiency of the rolling brush 500 and the cleaning effect of the cleaning equipment on which the rolling brush 500 is installed. Figure 3

[0029] As shown in the figure, in addition to the knife bodies 505, the rolling brush 500 further comprises a brush body 501, which is a hollow columnar structure, so as to constitute the main body of the entire rolling brush 500 and serve as the installation basis of the remaining components of the rolling brush 500. One end of the brush body 501 is configured to be connected to the driving device 400 of the cleaning equipment, so that the brush body 501 can roll on the surface to be cleaned under the driving of the driving device 400, thereby gathering the dirt attached to the surface to be cleaned. Figure 3 Specifically, as shown in the figure, an axial end of the brush body 501 is provided with a connecting part 5011, and 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 driving of the driving device 400, thereby gathering the dirt attached to the surface to be cleaned. In addition, as shown in the figure, the other axial end of the brush body 501 is provided with a support seat 502, and the other axial end of the brush body 501 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.

[0030] Figure 3 In addition, as shown in the figure, the rolling brush 500 further comprises a cleaning piece 503, which is integrally formed or rootedly connected to the peripheral side of the brush body 501. The cleaning piece 503 has a certain elasticity, so as to contact the surface to be cleaned in the process of rotating the rolling brush 500, and roll to clean and gather the dirt on the surface to be cleaned. Figure 3

[0031] In addition, as shown in the figure, the rolling brush 500 further comprises a cleaning piece 503, which is integrally formed or rootedly connected to the peripheral side of the brush body 501. The cleaning piece 503 has a certain elasticity, so as to contact the surface to be cleaned in the process of rotating the rolling brush 500, and roll to clean and gather the dirt on the surface to be cleaned. Figure 3

[0032] As shown in the figure, in addition to the knife bodies 505, the rolling brush 500 further comprises a brush body 501, which is a hollow columnar structure, so as to constitute the main body of the entire rolling brush 500 and serve as the installation basis of the remaining components of the rolling brush 500. One end of the brush body 501 is configured to be connected to the driving device 400 of the cleaning equipment, so that the brush body 501 can roll on the surface to be cleaned under the driving of the driving device 400, thereby gathering the dirt attached to the surface to be cleaned. 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 500 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 500 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 are provided.

[0033] 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 500 on the carpet and other surfaces to be cleaned, while preventing hair and other tangled objects from being blocked by the bristles 5033 as the roller brush 500 rotates. It should be noted that the roller brush 500 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.

[0034] 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 4In the shown embodiment, the cleaning strip 5032 is folded by arranging the 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 object can be guided to the working area of the cutter body 505. As shown in the figure, Figure 4 In the shown embodiment, the folding rib 50323 is arranged in the middle of the cleaning strip 5032, but it can be understood that the folding rib 50323 can also be arranged at other positions of the cleaning strip 5032 to guide the winding object to the working area of the cutter body 505.

[0035] In addition, as shown in the figure, Figure 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 is arranged to include two cleaning sections with opposite rotation directions, and during the rolling of the roller brush 500 on the ground, the hair and other winding objects 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 500, and correspondingly, the working area of the cutter body 505 can be arranged between the two cleaning sections. In specific implementation, the two cleaning sections can be connected together at one end close to each other by the folding rib 50323, so as to guide the winding object contacting the two cleaning sections to the working area of the cutter body 505. 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.

[0036] In another embodiment, Figure 4 As shown in the figure, the two cleaning sections can also not be connected, so that the hair and other winding objects 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.

[0037] 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 500 on the ground, the hair and other winding objects can also move along the arrangement direction of the cleaning strip 5031 with the rotation of the roller brush 500.

[0038] In another embodiment, Figure 4 As shown in the figure, the cleaning strip 5032 can also be designed as a whole streamline, and does not need to have Figure 4The folding rib 50323 shown, or the segmented connecting rib, does not need to bear the function of folding the cleaning section into a spiral or curved shape, so that the hair and other entanglements can be directly gathered to the working area of the cutter body 505 along the streamlined cleaning strip 5032. Among them, the hair and other entanglements can be gathered from both ends of the cleaning strip 5032 to the middle, or from any one section of the cleaning strip 5032 to the other section, to reach the working area of the cutter body 505.

[0039] In another embodiment, Figure 4 The cleaning strip 5032 shown can also be directly designed as a whole, without having Figure 4 The folding rib 50323 shown, or the segmented connecting rib, does not need to bear the function of folding the cleaning section into a spiral or curved shape, so that the hair and other entanglements can be directly gathered to the working area of the cutter body 505 along the streamlined cleaning strip 5032. Among them, the hair and other entanglements can be gathered from both ends of the cleaning strip 5032 to the middle, or from any one section of the cleaning strip 5032 to the other section, to reach the working area of the cutter body 505.

[0040] Figure 5 For Figure 3 The structure diagram of the rolling brush 500 shown, combined Figure 5 The cutting groove 504 is provided on the peripheral side of the brush body 501, and penetrates the inner and outer peripheral sides of the brush body 501. The cutting groove 504 is communicated with the inside of the brush body 501, and is passed through by the cutting edge of the cutter body 505, so that the cutter body 505 cuts the entanglements entangled on the brush body 501. The cutting groove 504 is externally provided with a protection tooth 506 to avoid direct contact of the user or the surface to be cleaned with the cutting edge. Among them, the cutting edge of the cutter body 505 is at least partially set to be higher than the cutting groove 504, but lower than the protection tooth 506. The specific form of the cutting groove 504 and how the cutting groove 504 is internally provided with the cutter body 505 will be described in detail below. Figure 6 The specific form of the cutting groove 504 and how the cutting groove 504 is internally provided with the cutter body 505 will be described in detail below.

[0041] Figure 6 For Figure 3 The radial cross-sectional view of the rolling brush 500 shown. As Figure 6 In an embodiment, the cutting groove 504 is two, and is provided in opposite penetration along the hollow brush body 501. The cutter body 505 includes a first cutter body 5051 ( Figure 7 shown) and a second cutter body 5052 ( Figure 8As shown in the drawings, the first cutter body 501 is provided with cutting edges on both sides, and the cutting edges on both sides of the first cutter body 501 are arranged on both sides of the brush body 501 and can protrude into the corresponding cutting grooves 504. The second cutter body 5052 is provided with two, and the cutting edges of the two second cutter bodies 5052 are arranged on both sides of the brush body 501 and protrude into the corresponding cutting grooves 504. The cutting edges of each second cutter body 5052 and the cutting edges of the first cutter body 5051 are oppositely arranged, so that the cutting edges of the first cutter body 5051 and the cutting edges of the second cutter body 5052 are at least partially higher than the cutting grooves 504, and the relative movement of the cutting edges of the first cutter body 5051 and the cutting edges of the second cutter body 5052 can cut the winding material wound on the brush body 501, thereby improving the cutting efficiency.

[0042] In another embodiment, the cutting grooves 504 arranged on the side of the brush body 501 are one, and correspondingly, the cutting edges of the first cutter body 5051 are one, and the second cutter body 5052 is also one, so that the cutting edges of the first cutter body 5051 and the cutting edges of the second cutter body 5052 can cut the winding material wound on the brush body 501 by cooperation.

[0043] In combination Figure 5 and Figure 6 In an embodiment, the cutting grooves 504 are substantially long strip-shaped, which are arranged between the two ends of the brush body 501 along the axial direction of the brush body 501. The cutting grooves 504 have a suitable size, so that the cutter body 505 has sufficient cutting range (i.e. working area) in the cutting grooves 504, thereby ensuring the cutting effect of the winding material wound on the brush body 501. In combination Figure 5 and Figure 6 The cutting grooves 504 can be arranged between at least two adjacent ones of the cleaning strips 5031, wherein the adjacent ones can be adjacent in the axial direction or adjacent in the circumferential direction.

[0044] In combination Figure 5 and Figure 6 In an embodiment, the protection tooth 506 includes two single structures, which are integrally formed on the side of the brush body 501 and oppositely arranged on both sides of the slot of the cutting groove 504 arranged on the side of the brush body 501. In another embodiment, the protection tooth 506 can also be a whole structure, which is integrally formed on the outside of the slot of the cutting groove 504 arranged on the side of the brush body 501. In addition, it should be noted that the brush body 501 of the present application can also include at least two single structures which can be detachably connected, so as to facilitate the assembly and maintenance and replacement of the brush body 501 and the related components therein.

[0045] The protective tooth 506 is protruded from the cutting groove 504, and the cutter body 505 is arranged in the cutting groove 504, and the cutting edge of the cutter body 505 is at least partially higher than the cutting groove 504 but lower than the protective tooth 506 (i.e. in the protective tooth 506), so that the protective tooth 506 can cover the part of the cutter body 505 protruding from the cutting groove 504, to prevent the user from being hurt by the exposed cutter body 505 or the cutting edge thereof, to prevent the flexible surface to be cleaned from being hurt by the exposed cutter body 505 or the cutting edge thereof, or to prevent the cutter body 505 or the cutting edge thereof from contacting the rigid surface to be cleaned or the dirt to cause excessive wear. The protective tooth 506 is provided with a plurality of tooth portions, and the tooth portions are provided with tooth gap portions which are communicated with the cutting groove 504. Hair and other winding objects can fall into the cutting groove 504 from the tooth gap portions and be cut by the cutter body 505, so as to be sucked into the dust box 200 Figure 2 The dust box (also referred to as a dirt collecting member) 200 shown in the figure can effectively improve the operation efficiency of the roller brush 500, prolong the service life of the roller brush 500, and improve the cleaning efficiency of the cleaning equipment provided with the roller brush 500. At the same time, the protective tooth 506 can play a role in pre-combing the winding objects, so that the winding objects are more easily guided or fall into the working area of the cutter body 505. In addition, the protective tooth 506 is protruded from the brush body 501, and although the protective tooth 506 is generally not higher than the height of the cleaning member 503, in some cases, the protective tooth 506 can play a role in pre-contacting the surface to be cleaned, avoiding the cutter body 505 directly contacting the surface to be cleaned, causing damage to the surface to be cleaned or the cutter body 505, so as to protect the surface to be cleaned or the cutter 505, improve the user experience and / or the service life of the cutter body 505. Figure 3

[0046] In addition, in an embodiment, since the fan 100 of the cleaning equipment can suck away the cut hair and other winding objects when the cleaning equipment is in operation, a small gap can be provided between the first cutter body 5051 and the second cutter body 5052 to maintain the smoothness of the relative movement between the first cutter body 5051 and the second cutter body 5052.

[0047] However, in another embodiment, the cutting edge of the first cutter body 5051 is configured to be attached to the second cutter body 5052 or the cutting edge thereof, to avoid the hair and other winding objects entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052 to a certain extent, affecting the operation of the brush body 501. However, under the condition of long-term use of the cleaning equipment, since the cutting edge of the first cutter body 5051 is relatively reciprocated with the second cutter body 5052, and the two are attached to each other, the cutting edge of the first cutter body 5051 and / or the second cutter body 5052 will be worn to a certain extent, resulting in a gap between the two or the original gap being enlarged. Based on this, in combination with the above-mentioned embodiment, the cutting edge of the first cutter body 5051 is configured to be attached to the second cutter body 5052 or the cutting edge thereof, to avoid the hair and other winding objects entering the brush body 501 through the gap between the first cutter body 5051 and the second cutter body 5052 to a certain extent, affecting the operation of the brush body 501. Figure 6 ​The rolling brush 500 of the present application further comprises elastic members 507, which can compensate for the wear of the cutting edges of the first cutter body 5051 and / or the second cutter body 5052, so that the cutting edges of the first cutter body 5051 and the second cutter body 5052 are kept in close contact, to avoid the entry of the entanglements such as the uncut or cut hairs into the brush body 501 through the gap between the two, and affect the operation of the brush body 501. Specifically, as shown in Figure 6 the elastic members 507 are arranged between the cutting edges of the first cutter body 5051 and the groove walls of the cutting groove 504, and between the second cutter body 5052 and the groove walls of the cutting groove 504, to compensate for the wear caused by the relative movement of the first cutter body 5051 and the second cutter body 5052, so that the two are kept in close contact. In another embodiment, the elastic members 507 can be arranged only between the cutting edges of the first cutter body 5051 and the groove walls of the cutting groove 504, or only between the second cutter body 5052 and the groove walls of the cutting groove 504, to compensate for the wear of at least one of the first cutter body 5051 and the second cutter body 5052, so that the two are kept in close contact.

[0048] Figure 9 For the schematic view of the first cutter body 5051 arranged side by side inside the brush body 501, in combination with Figures 7-9 the second cutter body 5052 is a long strip structure, and its length is slightly smaller than the length of the cutting groove 504, so that the second cutter body 5052 can reciprocate in the cutting groove 504; the first cutter body 5051 is arranged in multiple along the axial direction of the brush body 501, and the multiple first cutter bodies have gaps therebetween, so that at least one of the first cutter bodies can reciprocate independently of each other. The overall length of the cutting edges of the multiple first cutter bodies 5051 and the overall length of the second cutter body 5052 are substantially the same, to ensure the cutting effect on the entanglements on the surface of the rolling brush 500. In addition, the first cutter body 5051 is further relatively provided with two avoiding recesses 5053, which are arranged between the two cutting edges of the first cutter body 5051, to reduce the occupied space of the first cutter body 5051 inside the brush body 501, improve the swinging amplitude of the first cutter body 5051, and then improve the shearing effect on the entanglements.

[0049] In combination with Figure 9In an embodiment, at least two first blades are arranged in parallel along the axial direction of the brush body 501, and the first blades are identical in structure. The first blade 5051 is any one of the first blades. Therefore, the cutting edge of each first blade needs to be provided with an elastic member 507 that can abut against it.
