Figure 43 DETAILED DESCRIPTION In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0052] With the development of science and technology, cleaning equipment has become more and more popular, and floor cleaning work in units such as families and offices has been gradually replaced by cleaning equipment.

[0053]

[0054] ​​​​​​The specific technical solutions will be explained in detail with reference to the drawings which are not necessarily drawn to scale. Similar or identical reference numerals can be used to refer to similar or identical parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all the drawings comprising the similar or identical reference numerals constitute a single or same embodiment. The drawings generally illustrate various embodiments discussed in the present application in an exemplary but non-limiting manner.

[0055] Figure 1 A structural schematic diagram of the dirt collection assembly 10 described in an embodiment of the present application, Figure 2 For Figure 1 A wind path schematic diagram of the dirt collection assembly 10. In combination with Figure 1 And Figure 2 The dirt collection assembly 10 comprises 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 collection member) 200. During the operation of the cleaning device, the driving device 400 drives the rolling brush 500 to run on the surface to be cleaned to collect the dirt on the surface to be cleaned. At this time, the fan 100 is in an operating state to suck the dirt collected by the rolling brush 500 into the dust box 200 through the dirt guide cover 300, thereby automatically completing the cleaning of the surface to be cleaned. It should be noted that Figure 1 And Figure 2 Only to facilitate the reader to understand, a kind of installation and possible application environment of the rolling brush 500 is shown, and it can be understood that the rolling brush 500 can be installed or applied in other dirt collection assemblies or cleaning devices, and the corresponding cleaning effect can also be achieved.

[0056] Since the dirt on the surface to be cleaned can be hair or other winding objects, when the rolling brush 500 performs the cleaning action, the hair or other winding objects can easily wind around the rolling brush 500 along with the rotation of the rolling brush 500. If too much winding object is wound around 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.

[0057] Based on the above technical problem, the rolling brush 500 provided by the present application comprises at least one cutter body which can move relative to the brush body under the drive of the transmission member, so as to cut the winding object wound around the surface of the rolling brush 500, thereby avoiding the rolling brush 500 from making an abnormal sound, deforming or affecting the operation of the rolling brush 500 itself or the cleaning device in which the rolling brush 500 is installed, and improving the cleaning effect of the cleaning device. The rolling brush 500 described in multiple embodiments of the present application will be explained in detail below. Figures 3 to 43 The rolling brush 500 described in multiple embodiments of the present application will be explained in detail below.

[0058] Figure 3 A structural schematic diagram of the rolling brush 500a described in an embodiment of the present application, which is one kind of rolling brush 500. As shown in Figure 3As shown, the roller brush 500a includes at least one cutting assembly, each cutting assembly including at least one rotating blade. This rotating blade is capable of cutting away any debris that may become 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. (See attached diagram.) Figure 14 -Appendix Figure 19 Further details regarding the 500a roller brush are described below.

[0059] 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 on which the roller brush 500a is installed.

[0060] 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.

[0061] 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 3 As 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.

[0062] 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.

[0063] like Figure 3As 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 are provided.

[0064] 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.

[0065] 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.

[0066] 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 500a 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 500a, 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.

[0067] 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.

[0068] In another embodiment, the cleaning strip 5032 can be at least partially arranged in a straight line, an inclined line or / and an arc, 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 winding objects can also move along the arrangement direction of the cleaning strip 5031 with the rotation of the roller brush 500a.

[0069] In another embodiment, Figure 4 As shown in the figure, the cleaning strip 5032 can also be designed as a whole in a streamline shape, and does not need to have Figure 4The 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.

[0070] 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.

[0071] Combination Figure 3 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.

[0072] Figure 5 for Figure 3 The radial cross-sectional view of the brush body 501 of the roller brush 500a is shown. Figure 5 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 cutting assembly includes a first blade body 5051 ( Figure 6 As shown), the first blade 5051 is rotatably configured, and 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, 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.

[0073] Combination Figure 5In an embodiment, the protective tooth 506 comprises two single structures which are integrally formed on the circumferential side of the brush body 501 and oppositely arranged on both sides of the slot opening of the cutting slot 504 formed on the circumferential side of the brush body 501. In another embodiment, the protective tooth 506 can also be a whole structure which is integrally formed on the outside of the slot opening of the cutting slot 504 formed on the circumferential side of the brush body 501. In addition, it should be noted that the brush body 501 of the present application can also comprise at least two single structures which are detachably connected, so as to facilitate the assembly and maintenance and replacement of the brush body 501 and the related components therein.

[0074] The protective tooth 506 is protruded from the slot opening of the cutting slot 504, the cutter body 505 is arranged in the slot opening of the cutting slot 504, and the cutting edge thereof is at least partially higher than the slot opening of the cutting slot 504 but lower than the protective tooth 506 (i.e. located in the protective tooth 506), so that the protective tooth 506 can cover the part of the cutter body 505 protruding from the cutting slot 504, thereby preventing the user from being injured by the exposed cutter body 505 or the cutting edge thereof, preventing the flexible surface to be cleaned from being damaged by the exposed cutter body 505 or the cutting edge thereof, or preventing 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 slot 504. Hair and other entanglements can fall into the cutting slot 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 500a, prolong the service life of the roller brush 500a, and improve the cleaning efficiency of the cleaning equipment provided with the roller brush 500a. At the same time, the protective tooth 506 can play a role in pre-combing the entanglements, so that the entanglements are more easily guided or fall into the working area of the cutter body 505. In addition, the protective tooth 506 is protruded on 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, and causing the surface to be cleaned or the cutter body 505 to be damaged, 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 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 500a, prolong the service life of the roller brush 500a, and improve the cleaning efficiency of the cleaning equipment provided with the roller brush 500a. At the same time, the protective tooth 506 can play a role in pre-combing the entanglements, so that the entanglements are more easily guided or fall into the working area of the cutter body 505. In addition, the protective tooth 506 is protruded on 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, and causing the surface to be cleaned or the cutter body 505 to be damaged, 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.

[0075] In combination with the above description, the protective tooth 506 can be integrally formed on the circumferential side of the brush body 501, and the cutter body 505 can be arranged in the slot opening of the cutting slot 504 formed on the circumferential side of the brush body 501. Figure 5In an embodiment, two cutting grooves 504 are formed on the circumferential side of the brush body 501, the two cutting grooves 504 are opposite to each other, and at least part of the cutting edges on the circumferential side of the cutter body 505 protrude from the two cutting grooves 504 to simultaneously cut the winding material wound on the brush body 501, thereby improving the cutting efficiency. In another embodiment, only one cutting groove 504 can be formed on the circumferential side of the brush body 501, and the cutter body 505 protruding from the cutting groove 504 can also achieve the purpose of cutting the winding material wound on the brush body 501.

[0076] In combination Figure 5 The cutting groove 504 can be in a strip shape, and has a suitable size so that the cutter body 505 has sufficient cutting range in the cutting groove 504 to ensure the cutting effect on the winding material wound on the brush body 501.

[0077] In combination Figure 5 In an embodiment, the cutting groove 504 can be arranged between two adjacent cleaning strips 5031. The winding material such as hair is supported on the cleaning strips 5031, but the winding material such as hair has flexibility, and the winding material such as hair supported between the two cleaning strips 5031 will fall into the cutting groove 504 and be cut by the cutter body 505 in the cutting groove 504. Figure 14 In combination Figure 14 The cutting groove 504 is arranged in the region between the middle portions of the two adjacent cleaning strips 5031. Under the condition that at least part of the cleaning strip 5031 is in a spiral shape, the winding material such as hair will move and gather in the region between the two cleaning segments 5032, and then be cut by the cutter body 505 in the cutting groove 504 between the two adjacent cleaning strips 5031, thereby greatly cutting the winding material such as hair to effectively reduce the winding material on the surface of the roller brush and improve the cleanliness of the surface of the roller brush.

Figure 11 The at least one cutting assembly further comprises a second cutter body 5052 fixedly arranged in the brush body 501, at least part of the cutting edges of the second cutter body 5052 protruding into the cutting groove 504, and the second cutter body 5052 oppositely arranged with the first cutter body 5051. 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 with the second cutter body 5052, the fixed hair and other winding objects are cut by the second cutter body 5052 rotating relative to the first cutter body 5051, and the shearing effect on the hair and other winding objects is improved. The at least one cutting assembly comprising the second cutter body 5052 means that each cutting assembly can comprise the second cutter body 5052, the first cutter bodies 5051 of the two cutting assemblies are rotatable relative to the second cutter body 5052; or only one cutting assembly has the second cutter body 5052, the first cutter body 5051 of one of the cutting assemblies is rotatable relative to the second cutter body 5052, and the other cutting assembly only has a rotatable first cutter body 5051.

[0091] Figure 8 is a schematic view of the assembly of the cutting assembly in the brush body 501. Figure 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.

[0092] Figure 8 is a schematic view of the assembly of the cutting assembly in 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 running, the first cutter body 5051 and the second cutter body 5052 can also have a small gap therebetween.

[0093] Figure 12 Figure 9 is a schematic view of the structure of the first cutter body 5051 in the cutting assembly of Figure 11 Figure 10 is a schematic view of the structure of the second cutter body 5052 in the cutting assembly of Figure 13 Figure 10 is a schematic view of the structure of the second cutter body 5052 in the cutting assembly of Figure 11 Figure 10 is a schematic view of the structure of the second cutter body 5052 in the cutting assembly of Figure 12 Figure 10 is a schematic view of the structure of the second cutter body 5052 in the cutting assembly of Figure 13A plurality of heat dissipation holes 5059 are arranged on the first cutter body 5051 and / or the second cutter body 5052, and 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, reduce the friction, make the first cutter body 5051 rotate smoothly relative to the second cutter body 5052, and improve the service life of the first cutter body 5051 and the second cutter body 5052.

[0094] In combination Figures 11-13 The brush body 501 is provided with a containing cavity 5013, the cutting groove 504 and the containing cavity 5013 are communicated, the second cutter body 5052 is fixedly arranged in the containing cavity 5013, the first cutter body 5051 is rotatably arranged in the containing cavity 5013, and at least one of the outer sides of the first cutter body 5051 and the second cutter body 5052 and the containing 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 or / and 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 or / and the second cutter body 5052, so that the first cutter body 5051 and the second cutter body 5052 remain in close contact, so as 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, and avoid affecting the operation of the internal components of the brush body 501.

[0095] In combination Figures 11-13In an embodiment, the accommodating cavity 5013 comprises a first accommodating cavity 50131, the second cutter body 5052 is assembled in the first accommodating cavity 50131 in a matching manner, the sidewall of the first accommodating cavity 50131 is provided with a limiting recess 50133, two limiting recesses 50133 can be provided oppositely, the circumferential side of the second cutter body 5052 is provided with a first limiting protrusion 5058, the first limiting protrusion 5058 is inserted into the corresponding limiting recess 50133, so that the second cutter body 5052 can be assembled in the first accommodating cavity 50131 in a relatively fixed manner. The accommodating cavity 5013 further comprises a second accommodating cavity 50132, the second accommodating cavity 50132 and the first accommodating cavity 50131 are communicated, 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.

[0096] Figure 14 For Figure 11 the structure diagram of the elastic member 507 in the toothbrush 500. In combination with Figure 14 , 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 brush body 501.

[0097] Figure 15 is the assembly diagram of the first cutter body 5051 and the driven gear 5085, Figure 16 is the structure diagram of the partition member 513. In combination with Figure 15 and Figure 16A 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.

[0098] 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.

[0099] Figure 17 For Figure 16 the structure of the driving member 5081. In combination with Figure 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 rotation speed of the power output shaft 5089 can be reduced to an appropriate range, and the rotation speed of the driven gear 5085 and the first cutter body 5051 is also reduced, so as to reduce noise and reduce the wear of the first cutter body 5051 and the second cutter body 5052.

[0100] In combination with Figure 17 , 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 travels 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.

[0101] In combination with Figure 17One 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.

[0102] 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.

[0103] 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.) Figure 18 -Appendix Figure 19 The structure of the planetary gear reducer is further explained.

[0104] Figure 18 This is a structural schematic diagram of the 5088 reduction mechanism. (Combined with...) Figure 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.

[0105] Figure 19 for Figure 18 The diagram shown is of the internal structure of the deceleration mechanism 5088. Figure 19The 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.

[0106] In combination Figure 19 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.

[0107] By analogy, the speed reduction requirement can be achieved by the matched center wheel, planetary wheel and planet carrier, and the appropriate number of matched center wheel, planetary wheel and planet carrier can be set according to the speed reduction requirement, which will not be described here.

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.

[0115] Combination Figures 21-23The 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.

[0116] Figure 24 For Figure 20 the structure diagram of the first cutter body 5051 in the first cutter body 5051. In combination with Figure 24 , the first cutter body 5051 is generally circular, and in order to prevent the first cutter body 5051 from rotating, at least part of the circumferential side of the first cutter body 5051 is provided with a first limiting protrusion 5058 which is inserted into the inner wall of the containing cavity 5013, so that the first cutter body 5051 can be fixed relative to the brush body 501. In specific implementation, the first limiting protrusion 5058 is provided with two, and the two first limiting protrusions 5058 are arranged on the circumferential side of the first cutter body 5051 in the first direction, and the cutting edge of the first cutter body 5051 is arranged on the circumferential side of the first cutter body 5051 in the second direction, and the second direction and the first direction are arranged intersectingly.

[0117] Figure 25 For Figure 20 the structure diagram of the second cutter body 5052 in the second cutter body 5052. In combination with Figure 25The second cutter body 5052 is substantially circular. Since the second cutter body 5052 reciprocates, the cutting teeth can be arranged on the circumferential side of the second cutter body 5052 as the cutting edges of the second cutter body 5052. The cutting teeth on the circumferential side of the second cutter body 5052 protrude into the cutting groove 504 of the brush body 501 and reciprocate in the cutting groove 504 to shear the entangled objects that may be entangled on the rolling brush. In another embodiment, the cutting teeth can also be arranged on the circumferential side of the second cutter body 5052, i.e., the cutting teeth are annular, so that the circumferential side of the second cutter body 5052 serves as the cutting edge of the second cutter body 5052.

[0118] Figure 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 sheared 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. In another embodiment, since the air blower of the cleaning device can suck the sheared 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.

[0119] In combination Figure 26 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 a certain extent, which may cause a gap between the two. Based on this, the present 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 sheared 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.

[0120] In combination Figure 26In an embodiment, the elastic member 507 is arranged between the outer side of the second cutter body 5052 and the side wall of the accommodating cavity 5013. In order to prevent the elastic member 507 from rotating with the second cutter body 5052, at least a part of the circumferential side of the elastic member 507 is provided with a second limiting protrusion 5071, so that the elastic member 507 has a non-circular structure. The second limiting protrusion 5071 on the circumferential side of the elastic member 507 is in abutment with the inner wall of the accommodating cavity 5013, so that the second elastic member 507 can be fixed relative to the brush body 501, to 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 are kept in close contact. In a specific implementation, the second limiting protrusion 5071 is provided with two second limiting protrusions 5071, which are arranged on the circumferential side of the elastic member 507. In another embodiment, the elastic member 507 can also be arranged between the outer side of the first cutter body 5051 and the side wall of the accommodating cavity 5013, or the elastic member 507 is arranged between the outer side of the first cutter body 5051 and the second cutter body 5052 and the side wall of the accommodating cavity 5013.

[0121] Figure 27 For Figure 20 the assembly of the transmission member 508 and the second cutter body 5052. In combination with Figure 27 The roller brush further comprises a transmission member 508, which is arranged in the brush body 501. The transmission member 508 is connected with the second cutter body 5052, and drives the second cutter body 5052 to reciprocate relative to the first cutter body 5051 through the transmission member 508, so as to shear the entangled objects that may be entangled on the roller brush.

[0122] In combination with Figure 27 According to an embodiment of the present application, the transmission member 508 comprises a driving member 5081, a first driving shaft 50810, a second driving shaft 50811 and a swing arm 5082. The driving member 5081 is provided with a rotatable driving portion. The first driving shaft 50810 is eccentrically connected to the driving portion of the driving member 5081. The second driving shaft 50811 is eccentrically connected to the second cutter body 5052. 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.

[0123] In combination with Figure 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.

[0124] In combination Figure 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. 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.

[0125] In combination Figure 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. If the length of the transmission shaft is relatively short, only one second support member 514 can be arranged.

[0126] In combination Figure 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.

[0127] In an embodiment, in combination Figure 27The transmission member 508 further comprises a transfer gear 50814 coaxially connected with the worm gear, i.e. the transfer gear 50814 and the worm gear share a same central shaft so that the transfer gear 50814 and the worm gear rotate synchronously. 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.

[0128] In combination Figure 27 In an embodiment, the transmission member 508 further comprises a second transmission gear 50815 rotatably connected in the brush body 501 and connected with the transfer gear 50814 and the first transmission gear 50813 respectively. 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.

[0129] In combination Figure 27 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.

[0130] In combination Figure 27In 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.

[0131] 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.

[0132] Figure 28 This is a schematic diagram of another type of roller brush 500c according to this application. (Combined with...) Figure 28 This application provides a roller brush 500c, 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. (See attached image.) Figure 28 -Appendix Figure 34 The specific details of the roller brush are further described below.

[0133] Figure 28 The roller brush 500c shown is a type of roller brush 500, similar to roller brush 500b. The main difference between the two is that the blade of roller brush 500c is rotating, while the blade of roller brush 500b is reciprocating. Roller brush 500c 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 500a are largely the same as those in roller brush 500b, and therefore can be referred to the corresponding description of the roller brushes described above, which will not be repeated here.

[0134] Figure 29 for Figure 28 A schematic diagram of the radial cross-section. Combined with... Figure 29The blade body 505 of the roller brush 500c 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.

[0135] Figure 30 for Figure 28 An internal diagram. Combined with... Figure 29 as well as Figure 30 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.

[0136] Figure 31 for Figure 28 A structural schematic diagram of the first cutting tool body 5051. (Combined with...) Figure 31 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.

[0137] Figure 32 for Figure 28 A schematic diagram of the structure of the second cutter body 5052. (Combined with...) Figure 32 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.

[0138] Figure 33 This is a schematic diagram showing the assembly of the blade body 505 within the brush body 501. (Combined with...) Figure 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.

[0139] Combination Figure 33 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.

[0140] Combination Figure 33The 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 a specific implementation, the elastic member 507 can be in a ring structure, and the gap of the ring structure is sleeved on the support shaft 5054, so as to rotate with the second cutter body 5052 around the support shaft 5054, and the elastic member 507 is fixedly arranged on the side wall of the accommodating cavity 5013, so as to compensate for the wear of the first cutter body 5051 or / and the second cutter body 5052.

[0141] In combination Figure 33 The side wall of the accommodating cavity 5013 is provided with a mounting portion 50132, which can be in a hole structure or a groove structure. A part of the elastic member 507 is arranged in the mounting portion 50132 by means of adhesion, interference fit or the like. Another part of the elastic member 507 abuts against the second cutter body 5052, 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.

[0142] Figure 34 The figure shows the assembly of the transmission member 508 and the second cutter body 5052. In combination Figure 34 The rolling brush further comprises a transmission member 508, which is arranged in the brush body 501 and connected with the second cutter body 5052, so as to drive the second cutter body 5052 to rotate relative to the first cutter body 5051, and cut the entanglements possibly entangled on the rolling brush. The specific details of the transmission member 508 are further described by means of the figures.

[0143] In combination Figure 34 According to an embodiment of the present application, the transmission member 508 comprises a driving member 5081 and a worm and gear mechanism 50812. The driving member 5081 is provided with a rotatable driving portion. The worm of the worm and gear mechanism 50812 is in transmission connection with the driving portion. The worm wheel is rotatably connected in the brush body 501 around the support shaft 5054. In an embodiment, the second cutter body 5052 is connected with the support shaft 5054. Under the condition that the driving member 5081 rotates, the support shaft 5054 is driven to rotate by the worm and gear mechanism 50812, so as to drive the second cutter body 5052 connected with the support shaft 5054 to rotate. The rotating second cutter body 5052 cooperates with the fixed first cutter body 5051, so as to cut the entanglements possibly entangled on the rolling brush. In another embodiment, the second cutter body 5052 is directly connected with the worm. Under the condition that the worm rotates, the second cutter body 5052 is directly driven to rotate synchronously with the worm. The rotating second cutter body 5052 cooperates with the fixed first cutter body 5051, so as to cut the entanglements possibly entangled on the rolling brush.

[0144] In combination Figure 33In an embodiment, the fixed first cutter 5051 is arranged between the rotatable second cutter 5052 and the worm gear mechanism 50812 to facilitate the arrangement of the elastic member 507. In another embodiment, if the interior space of the brush body 501 allows, the rotatable second cutter 5052 can also be arranged between the fixed first cutter 5051 and the worm gear mechanism 50812.

[0145] In combination Figure 34 According to an embodiment of the present application, the worm can be arranged in parallel to the axial direction of the brush body 501, and two fourth support members 516, which can be bearings or copper bushings, are arranged in the brush body 501, and 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.

[0146] In combination Figure 34 The driving member 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 the first transmission wheel 50813 is configured as a driving part. The second transmission wheel 50815 is connected to the worm, and the second transmission wheel 50815 is engaged with the first transmission wheel 50813. Under the condition that the power input shaft 5087 rotates, the worm gear mechanism 50812 can be driven to act through the engagement transmission of the first transmission wheel 50813 and the second transmission wheel 50815, and in turn the second cutter 5052 is driven to rotate to shear the entanglements that can be entangled on the rolling brush.

[0147] In combination Figure 34 One end of the power input shaft 5087 can be connected to the support seat 502 at the other end of the axial direction of the brush body 501. When the rolling brush travels and rolls on the ground, the power input shaft 5087 rotates relative to the brush body 501 to drive the worm gear mechanism 50812 to act, and in turn the second cutter 5052 is driven to rotate to shear the entanglements that can be entangled on the rolling brush.

[0148] In combination Figure 34 More than one second support member 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 through 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 support member. In specific implementation, the number of second support members 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, multiple second support members 514 can be arranged. If the length of the power input shaft 5087 is relatively short, only one second support member 514 can be arranged.

[0149] In combination Figure 34 Since the power input shaft 5087 is driven by the first transmission wheel 50813 and the second transmission wheel 50815 in meshing engagement and the worm of the worm and gear mechanism 50812, and the power input shaft 5087 is coaxially arranged with the central shaft of the brush body 501, the worm of the worm and gear mechanism 50812 can be offset from the central shaft of the brush body 501, and then more space can be provided for the cutter body 505, so that the cutting assembly is arranged as much as possible at the center of the brush body 501 to improve the shearing effect on the entanglements that can be entangled on the roller brush. In other embodiments, the worm of the worm and gear mechanism can also be directly connected with the power input shaft 5087 to drive the second cutter body 5052 to be rotatably arranged relative to the first cutter body 5051.

[0150] In combination Figure 34 The radius of the second transmission wheel 50815 is greater than that of the first transmission wheel 50813 to reduce the rotation speed of the second transmission wheel 50815, and accordingly the output speed of the worm and gear mechanism and the rotation speed of the second cutter body 5052, so as to reduce the noise of the cleaning equipment in operation and reduce the wear of the first cutter body 5051 and the second cutter body 5052, which has good practicability.

In combination Figure 35 The roller brush 500d provided in the present application includes two cutter bodies 505, both of which can rotate to shear the entanglements that can be entangled on the roller brush, reduce the entanglements on the surface of the roller brush, improve the cleanliness of the surface of the roller brush, avoid affecting the operation of the roller brush and improve the cleaning effect of the cleaning equipment. The specific details of the roller brush 500d are further described with reference to the accompanying drawings.

[0154] Figure 35The shown rolling brush 500d is one of the rolling brushes 500, similar to the rolling brush 500c, the difference between the two mainly lies in that both of the two cutter bodies 505 of the rolling brush 500d are rotationally arranged, one of the two cutter bodies 505 of the rolling brush 500c is fixed, and the other cutter body 505 is rotatable. The rolling brush 500c also comprises the brush body 501, the cleaning member 503, the cutting groove 504, and the protection tooth 506, and unless otherwise specified, the structures and functions of these components in the rolling brush 500d are substantially the same as those of the rolling brush 500c described above, so reference can be made to the corresponding description of the rolling brush above, and will not be repeated here.

In combination Figure 36 The cutting groove 504 is formed on the circumferential side of the brush body 501, the cutting groove 504 is in communication with the inside of the brush body 501, and at least part of the cutting edges on the circumferential side of the two cutter bodies 505 of the cutting assembly are arranged in the cutting groove 504 to cut the entangled objects entangled on the brush body 501. In addition, the cutting groove 504 can be substantially in the form of a long strip, so as to have a suitable size, so that the cutter body 505 has sufficient cutting range in the cutting groove 504, and the cutting effect on the entangled objects entangled on the brush body 501 is guaranteed.

[0156] In combination Figure 36 Two cutting grooves 504 are arranged on the circumferential side of the brush body 501, the two cutting grooves 504 are arranged opposite to each other, and at least part of the cutting edges on the circumferential side of the two cutter bodies 505 of the cutting assembly protrude out of the two cutting grooves 504 to simultaneously cut the entangled objects entangled on the brush body 501, thereby improving the cutting efficiency. In another embodiment, each cutter body 505 can be provided with only one cutting groove 504, and the cutting edges of the cutter body 505 protruding out of the cutting groove 504 can also cut the entangled objects entangled on the brush body 501.

[0157] In combination Figure 36 The two cutter bodies 505 of the rolling brush 500d can be defined as a first cutter body 5051 and a second cutter body 5052, both of which are arranged in the brush body 501 and can rotate relative to the brush body 501, and at least part of the cutting edges on the circumferential side of the first cutter body 5051 and the second cutter body 5052 protrude out of the cutting groove 504, so that the two cutter bodies 505 that can rotate relative to the brush body 501 can cut the entangled objects that can be entangled on the rolling brush, thereby reducing the entangled objects on the surface of the rolling brush, improving the cleanliness of the surface of the rolling brush, and avoiding affecting the operation of the rolling brush, thereby improving the cleaning effect of the cleaning equipment.

[0158] In combination Figure 36The 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.

[0159] Figure 37 for Figure 35 An internal diagram. Combined with... Figure 36 as well as Figure 35 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.

[0160] Combination Figure 36 as well as Figure 37 In 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.

[0161] Combination Figure 36 as well as Figure 37 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.

[0162] Combination Figure 36 as well as Figure 37In an embodiment, the elastic member 507 is arranged between the end face of the two knife bodies 505 and the side wall of the accommodating cavity 5013 to compensate for the wear of the first knife body 5051 or / and the second knife body 5052, so that the two knife bodies 505 are kept in close contact. In another embodiment, the elastic member 507 can be arranged only between the end face of one of the two knife bodies 505 and the side wall of the accommodating cavity 5013 to compensate for the wear of the first knife body 5051 or / and the second knife body 5052, so that the two knife bodies 505 are kept in close contact.

[0163] Figure 38 For Figure 37 the structure of the elastic member 507. In combination with Figure 38 , the circumferential side of the elastic member 507 is provided with a second limiting protrusion 5071 which abuts against the side wall of the accommodating cavity 5013, so that the elastic member 507 can be kept fixed when the knife body 505 rotates, avoiding the elastic member 507 from rotating with the knife body 505.

[0164] Figure 39 For Figure 37 the structure of the knife body 505. In combination with Figure 39 In some embodiments, the first knife body 5051 or / and the second knife body 5052 is provided with a plurality of heat dissipation holes 5059 which can be circular or square in shape. On the one hand, the heat dissipation holes 5059 can dissipate heat when the first knife body 5051 rotates relative to the second knife body 5052. On the other hand, the heat dissipation holes 5059 can also reduce the contact area between the two knife bodies 505, thereby reducing the friction and making the rotation of the first knife body 5051 relative to the second knife body 5052 smooth, and improving the service life of the two knife bodies 505.

[0165] In combination with Figure 37 , the rolling brush further comprises a transmission member 508 which is arranged in the brush body 501 and connected with the two knife bodies 505 to drive the two knife bodies 505 to rotate simultaneously relative to the brush body 501, so as to shear the entangled objects which can be entangled on the rolling brush.

[0166] In an embodiment, the two knife bodies 505 rotate relative to each other to shear the entangled objects which can be entangled on the rolling brush through the relative movement of the shearing teeth on the circumferential side of the two knife bodies 505, so as to improve the shearing effect on the entangled objects. In another embodiment, the two knife bodies 505 can also rotate in the same direction at different speeds, i.e. the two knife bodies 505 have the same rotational speed but the rotational speed of one of the two knife bodies 505 is different from that of the other, which can also shear the entangled objects which can be entangled on the rolling brush. The specific details of the transmission member 508 will be described further. Figure 40 -Appendix Figure 43 The specific details of the transmission member 508 will be described further.

[0167] Figure 40 For Figure 37 the top view of the rolling brush, in combination with Figure 37 and Figure 40According to an embodiment of the present application, the transmission member 508 comprises a driving member 5081, a main gear 5083, two driven gears 5085 and a swing arm 5082. The driving member 5081 is provided with a rotatable driving portion, the main gear 5083 is connected to the driving portion, the two driven gears 5085 are rotatably arranged in the brush body 501, at least one of the driven gears 5085 is in conical surface cooperation with the main gear 5083, the two driven gears 5085 are eccentrically provided with swing shafts 50819, the swing arm 5082, the driven gear 5085, the cutter body 505 and the support shaft 5054 are arranged one by one, 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. Under the condition that the driving member 5081 rotates, the main gear 5083 and the driven gear 5085 in conical surface cooperation can drive the driven gear 5085 to rotate in the brush body 501, the swing shaft 50819 on the driven gear 5085 rotates synchronously with the driven gear 5085, the swing shaft 50819 reciprocates in the connecting recess 50820 of the corresponding swing arm 5082 to drive the support shaft 5054 to rotate, and then drive the two cutter bodies 505 to rotate relative to the brush body 501 to shear the entanglements possibly entangled on the roller brush.

[0168] In combination with Figure 37 and Figure 40 The two driven gears 5085 are connected to a connecting shaft 5055 which can be perpendicular to the central shaft of the brush body 501. A fixing member 512 is fixedly arranged in the brush body 501, the middle part of the connecting shaft 5055 is arranged in the fixing member 512, the two ends of the connecting shaft 5055 protrude out of the fixing member 512, and the two driven gears 5085 are connected to the two ends of the connecting shaft 5055 respectively. The fixing member 512 can be a columnar structure or a square structure. When the fixing member 512 is a columnar structure, the fixing member 512 is provided with a positioning protrusion 5121 on the side surface, the positioning protrusion 5121 is embedded into the inner wall of the brush body 501 to fix the fixing member 512 in the brush body 501, so that the fixing member 512 is prevented from being driven to rotate by the connecting shaft 5055.

[0169] In an embodiment, the connecting shaft 5055 is rotatably connected in the fixing member 512, and the two driven gears 5085 are fixedly assembled on the two ends of the connecting shaft 5055 by means of key connection or the like. When one of the driven gears 5085 is driven to rotate, the driven gear 5085 drives the connecting shaft 5055 to rotate in the fixing member 512, and in turn drives the other driven gear 5085 (not engaged with the main gear 5083) to rotate. In another embodiment, the connecting shaft 5055 is fixed in the fixing member 512 by means of key connection or the like, and the driven gears 5085 are rotatably connected on the connecting shaft 5055. The two driven gears 5085 are engaged with the gear 5085. When the two driven gears 5085 are driven to rotate, the two driven gears 5085 rotate around the connecting shaft 5055.

[0170] Figure 41 For Figure 37 , the structure diagram of the swing arm 5082 in the cutting tool 505 is shown. In combination with Figure 41 , in an embodiment, the connecting recess 50820 on the swing arm 5082 can be a waist-shaped hole, and the swing shaft 50819 can slide along the length direction of the waist-shaped 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 a waist-shaped groove, and the swing shaft 50819 can slide along the length direction of the waist-shaped groove to drive the support shaft 5054 at the other end of the swing arm 5082 to rotate.

[0171] In combination with Figure 41 , the overall shape of the swing arm 5082 can be a zigzag structure to adapt to the internal space of the brush body 501. The other end of the swing arm 5082 can be fixedly connected on the corresponding support shaft 5054 by means of key connection or the like. The other end of the swing arm 5082 is arranged between the first support member 5086 and the corresponding cutter body 505. A partition member is arranged between the swing arm 5082 and the corresponding cutter body 505. The partition member is clearance connected on the support shaft 5054. The partition member can be a wave-shaped gasket. The wave-shaped gasket can axially separate the corresponding cutter body 505 and the swing arm 5082 on the support shaft 5054, so as to avoid interference between the two. In addition, the contact between the partition member and the cutter body 505 and the swing arm 5082 is local contact, so as to reduce the friction area between the partition member and the cutter body 505 and the swing arm 5082, and make the cutter body 505 and the swing arm 5082 rotate smoothly.

[0172] In combination with Figure 40The driving member 5081 comprises a power input shaft 5084, a speed reduction mechanism 5088 and a power output shaft 5089 connected in sequence, wherein the power output shaft 5089 is configured as a driving part. Under the condition that the power input shaft 5084 rotates, the speed of the power output shaft 5089 can be reduced by the speed reduction mechanism 5088, so as to make the two cutter bodies 505 rotate at a suitable speed, thereby reducing the noise of the cleaning equipment and reducing the wear of the two cutter bodies 505, which has good practicability.

[0173] In combination Figure 40 One end of the power input shaft 5084 can be connected in the support seat 502 at the other end of the axial direction of the brush body 501. When the roller brush travels 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 cutter bodies 505 to rotate and shear the entanglements that can be entangled on the roller brush.

[0174] In combination Figure 40 More than one second support member 514 can be arranged in the brush body 501, and the power input shaft 5084 can rotatably pass through the second support member 514 to support the power input and output shaft through the second support member 514. The second support member 514 can be a bearing or a copper bushing, so that the power input shaft 5084 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 5084. If the length of the power input shaft 5084 is relatively long, a plurality of second support members 514 can be arranged. If the length of the power input shaft 5084 is relatively short, only one second support member 514 can be arranged. Similarly, a suitable number of second support members 514 can also be arranged on the power input shaft 5084.

[0175] The speed reduction mechanism 5088 in the roller brush 500d 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, so as to reduce the noise and reduce the wear of the first cutter body 5051 and the second cutter body 5052. In specific implementation, the speed reduction mechanism 5088 in the roller brush 500d can adopt the speed reduction mechanism 5088 in the roller brush 500a. That is, the speed reduction mechanism 5088 can be a planetary gear reducer. The planetary gear reducer has the characteristics of small volume, large carrying capacity and stable work, can adapt to the internal space of the brush body 501501, and can stably output power. The planetary gear reducer can have one or more stages of transmission. The more the number of stages is, the larger the speed reduction ratio is. The number of stages can be set according to the speed reduction requirement.

[0176] In combination Figure 42In an embodiment, the projections of the swing axes 50819 on the two driven gears 5085 are located at different positions on the same circle coaxial with the connecting shaft 5055 along the axial direction of the connecting shaft 5055. That is, the distance between the swing axes 50819 on the two driven gears 5085 and the central axis of the driven gears 5085 is consistent, but the line connecting the two swing axes 50819 intersects the connecting shaft 5055, so that the two cutter bodies 505 driven by the two driven gears rotate relative to each other to shear the entanglements that may be entangled on the roller brush, thereby improving the shearing effect on the entanglements. In specific implementation, the central angle of the circle formed by the projections of the swing axes 50819 on the two driven gears 5085 can be between 90-180°, for example, the projections of the swing axes 50819 on the two driven gears 5085 can be symmetrically arranged on the two sides of the circle, or the central angle of the circle formed by the projections of the swing axes 50819 on the two driven gears 5085 can be 90°, 135°, etc., which is not limited herein.

[0177] In combination Figure 43 In another embodiment, the projections of the swing axes 50819 on the two driven gears 5085 are located on two circles along the axial direction of the connecting shaft 5055, that is, the distance between the swing axes 50819 on the two driven gears 5085 and the connecting shaft 5055 is inconsistent, and under the condition that the two driven gears 5085 rotate, the rotation of the corresponding two cutter bodies 505 has a speed difference to shear the entanglements that may be entangled on the roller brush. 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.

[0178] In summary, the roller brush provided in the present application can shear the entanglements that may be entangled on the roller brush through the two rotating cutter bodies, reduce the entanglements on the surface of the roller brush, improve the cleanliness of the surface of the roller brush, reduce the resistance of the roller brush in operation, avoid affecting the operation of the roller brush, and also improve the cleaning efficiency of the roller brush, thereby improving the cleaning effect of the cleaning equipment, and having good practicability.
