In the present utility model, the "top", "bottom" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 3, and the "axial" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 4. It is to be understood that such directional terms are merely used to facilitate the description of the utility model and to simplify the description, and are not intended to indicate or imply that the devices or elements so referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus are not to be construed as limiting the utility model.

An embodiment of the present utility model provides a ground brush, referring to fig. 1 to 4 and fig. 10 and 11, the ground brush includes a housing 10, a first rolling brush 20, a shearing assembly 30, and a first driving device 40, the first rolling brush 20 is rotatably disposed in the housing 10, the shearing assembly 30 is proximate to the first rolling brush 20, the shearing assembly 30 includes a first cutting member 31 extending along an axial direction of the first rolling brush 20, and the first driving device 40 drives the first cutting member 31 to reciprocate along the axial direction of the first rolling brush 20.

Another embodiment of the present utility model provides a vacuum cleaner, including the floor brush according to any of the embodiments of the present utility model.

Specifically, the first rolling brush 20 is rotatable within the housing 10. The shearing assembly 30 is adjacent to the first rolling brush 20, and the shearing assembly 30 may be disposed close to the first rolling brush 20 but not in contact with the first rolling brush 20, or the shearing assembly 30 may be in contact with and interfere with the first rolling brush 20.

Illustratively, the first rolling brush is a bristle rolling brush, which includes a barrel 21 and bristles 22 disposed on an outer surface of the barrel 21, and a minimum distance between the shearing assembly 30 and the bristles 22 is greater than or equal to-0.2 mm and less than or equal to 0.5mm. The minimum distance is controlled within this range to ensure the shearing effect of the shearing module 30 on the foreign matters such as the hair wound around the first roller brush 20. Preferably, the minimum distance is greater than or equal to 0mm and less than or equal to 0.2mm. Wherein, the minimum distance refers to the distance between the outer surface of the side of the shearing assembly 30 close to the barrel 21 and the outer surface of the side of the bristle 22 away from the barrel 21. A positive distance value indicates that the two are not in contact, a 0 distance value indicates that the two are in contact, and a negative distance value indicates that the cutting assembly 30 extends into the implant 22, i.e., interferes with the implant 22.

The first cutting element 31 may extend in the axial direction of the first rolling brush 20, that is, the longitudinal direction of the first cutting element 31 may be parallel to the axis of the first rolling brush 20, or may have a certain angle, and may extend only in the axial direction of the first rolling brush 20, thereby improving the shearing effect on the sundries such as the hair wound around the first rolling brush 20.

The first driving device 40 is a power source capable of driving the first cutting member 31 to reciprocate, and the frequency of the first cutting member 31 can be set according to practical situations, for example, the frequency of the first cutting member 31 can be between 400 times/minute and 500 times/minute.

The shearing assembly 30 of the ground brush provided by the embodiment of the utility model is close to the first rolling brush 20, so that sundries such as hair wound on the first rolling brush 20 can be sheared by arranging the shearing assembly 30. In addition, the first driving device 40 drives the first cutting member 31 to reciprocate along the axial direction of the first rolling brush 20, so that the first cutting member 20 can automatically cut sundries such as hair on the first rolling brush 20 under the driving of the first driving device 40, and manual cleaning of a user is not needed, so that the cleaning of the hair on the rolling brush can be facilitated, and the use effect of the user can be further improved.

The specific structure and actual driving manner of the first driving device 40 are not limited.

Illustratively, the first driving device 40 includes a first driving motor 41, a worm 42, a worm wheel 43, and a first transmission assembly 44, the worm 42 and the worm wheel 43 are meshed with each other, the first driving motor 41 is in driving connection with the worm 42, the worm wheel 43 is in driving connection with the first transmission assembly 44, and the first driving motor 41 rotates by driving the worm 42, so that the first transmission assembly 44 drives the first cutting member 31 to reciprocate along the axial direction of the first rolling brush 20.

Specifically, the worm 42 and the worm wheel 43 are engaged with each other, and the first drive motor 41 can drive the worm wheel 43 to rotate by driving the worm 42 to rotate. The worm gear 43 is in driving connection with the first transmission assembly 44, and the specific driving connection manner is not limited, for example, the worm gear 43 and the first transmission assembly 44 rotate coaxially, and for example, the worm gear 43 and the first transmission assembly 44 rotate in a meshed manner. Thus, the worm gear 43 can transmit the driving force from the first driving motor 41 to the first transmission assembly 44, and drives the first cutting member 31 to reciprocate under the transmission action of the first transmission assembly 44. In an embodiment, referring to fig. 11 and 12, the first transmission assembly 44 includes a guide rod 441 eccentrically disposed with respect to the worm gear 43, the first cutting member 31 has a guide groove 31a, the extending direction of the guide groove 31a is perpendicular to the axial direction of the first rolling brush 20, the guide rod 441 extends into the guide groove 31a, and the first driving motor 41 rotates by driving the worm 42 to move the guide rod 441 rotating with the worm gear 43 along the extending direction of the guide groove 31a so as to drive the first cutting member 31 to reciprocate.

Specifically, the guide rod 441 is disposed eccentrically with respect to the worm wheel 43, i.e., the central axis of the guide rod 441 does not coincide with the central axis of the worm wheel 43. The extending direction of the guide groove 31a may be perpendicular to the axial direction of the first roller brush 20, or the longitudinal direction of the guide groove 31a may be perpendicular to the axial direction of the first roller brush 20, or both may be at a certain angle so that the longitudinal direction of the guide groove 31a is substantially perpendicular to the axial direction of the first roller brush 20. Thus, when the first driving motor 41 drives the worm 42 to rotate the worm wheel 43, the guide bar 441 can be rotated about the central axis of the worm wheel 43 due to the eccentric arrangement of the guide bar 441. By extending the guide rod 441 into the guide groove 31a, it is possible to push the groove wall of the guide groove 31a in the axial direction of the first rolling brush 20 while the guide rod 441 is moved in the extending direction of the guide groove 31a within the guide groove 31a, whereby the reciprocating movement of the first cutting member 31 along the axis of the first rolling brush 20 can be achieved.

It should be noted that, since the guide rod 441 actually performs a circular motion around the central axis of the worm wheel 43 when the worm 42 is driven to rotate by the first driving motor 41, the groove length of the guide groove 31a in the extending direction should be larger than the circumferential diameter of the guide rod 441 performing the circular motion. That is, the groove length thereof should satisfy the path length of the guide bar 441 moving along the extending direction of the guide groove 31a, so as to avoid that the guide bar 441 pushes the guide groove 31a along the extending direction of the guide groove 31a when the groove length of the guide groove 31a is insufficient, and also avoid that the guide groove 31a blocks the guide bar 441 moving along the extending direction, so that the structure of the guide bar 441 is damaged.

In addition, the specific manner in which the first transmission assembly 44 drives the first cutting member 31 to reciprocate may be determined according to the specific structure inside the ground brush, so as to facilitate the structural design of the ground brush, for example, the first transmission assembly 44 includes a crank mechanism, and the first cutting member 31 is driven to reciprocate along the axis of the first rolling brush 20 by the crank mechanism rotating into a linear motion.

In an embodiment, referring to fig. 12, the first transmission assembly 44 includes a rotating shaft 442 and a connecting member 443, the connecting member 443 and the worm gear 43 are both disposed on the rotating shaft 442, and the guide rod 441 is disposed on a side of the connecting member 443 facing away from the worm gear 43.

Specifically, the connection member 443 and the worm wheel 43 are rotatable about the rotation shaft 442 with their central axes overlapping, and the guide rod 441 is eccentrically disposed on a side of the connection member 443 facing away from the worm wheel 43, so that eccentric disposition of the guide rod 441 with respect to the worm wheel 43 can be achieved.

The specific shape of the connecting member 443 is not limited, and it may be a cylinder or other shapes that are convenient for processing and setting.

In one embodiment, referring to fig. 8, 9 and 11, the first cutting member 31 includes a cutting blade 311 and a connecting rod 312 connected to the cutting blade 311, and the connecting rod 312 has a guiding slot 31a.

Specifically, only one cutter 311 may be connected to the link 312, or a plurality of cutters 311 may be connected to the link 312, which are disposed at intervals in the axial direction of the first roll brush 20. The guide bar 441 moves in the extending direction of the guide groove 31a and pushes the link 312 to reciprocate along the axis of the first roll brush 20, thereby enabling the cutter 311 to cut the foreign matters such as hair on the first roll brush 20.

The cutting unit 30 may cut the sundries such as the hair wound around the first roller brush 20 only by the first cutting member 31, or may cut the sundries by a plurality of cutting members cooperating with each other.

Illustratively, referring to fig. 9, the shear assembly 30 includes a second cutter 32 extending in the axial direction of the first roller brush 20, the second cutter 32 being stationary relative to the housing 10.

Specifically, the first cutting member 31 and the second cutting member 32 cooperate with each other to cut the hair or the like. The first cutting member 31 reciprocates under the driving of the first driving device 40, and the second cutting member 32 is kept stationary relative to the housing 10, so that the relative movement between the first cutting member 31 and the second cutting member 32 can be realized, and the effect of cutting sundries such as hair can be improved.

It should be noted that, the cutter 311 and the second cutting member 32 may be serrated, so that, during the working process of the ground brush, the impurities such as the hair on the first rolling brush 20 may be thrown onto the serrated along with the movement of the first rolling brush 20, and the serrated can cut the impurities such as the hair by the relative movement.

In addition, the shearing module 30 may be provided with only one second cutting member 32 to be matched with the first cutting member 31, and may be provided with a plurality of second cutting members 32 along the axial direction of the first rolling brush 20, so that the second cutting members 32 do not need to be oversized, and the second cutting members 32 can be manufactured conveniently while ensuring the shearing effect of the shearing module 30 on sundries such as hair.

In one embodiment, the shearing assembly 30 includes a plurality of first cutting members 31 and a plurality of second cutting members 32, each of the second cutting members 32 is fixed on the housing 10 and extends along the axis of the first rolling brush 20, and the first cutting members 31 and the second cutting members 32 are disposed in a one-to-one correspondence.

In one embodiment, referring to fig. 5 and 7, the housing 10 includes a casing 11, the casing 11 having a first mounting groove 11a, and a suction port 11b and a first opening 11c communicating with the first mounting groove 11a, the suction port 11b being provided at one side of the first mounting groove 11a, the first opening 11c being provided at one side of the casing 11 near the suction port 11b and extending in an axial direction of the first rolling brush 20, the first rolling brush 20 being provided in the first mounting groove 11a, a shearing assembly 30 being provided at one side of the casing 11 facing away from the first rolling brush 20, and a first cutter 31 passing through the first opening 11c to extend into the first mounting groove 11 a.

Specifically, the suction port 11b communicates with the first mounting groove 11a, so that air flow from the outside through the first mounting groove 11a and then into the suction port 11b can be facilitated, the first opening 11c communicates with the first mounting groove 11a and is located on the side of the housing 11 close to the suction port 11b, and the first cutting member 31 can be arranged on the side close to the suction port 11b by passing the first cutting member 31 through the first opening 11c and extending into the first mounting groove 11a, whereby it is possible to facilitate that sundries such as hairs cut by the first cutting member 31 on the first rolling brush 20 enter the suction port 11b with the air flow, and it is possible to prevent the sundries such as the cut hairs from gathering in the housing 10.

When the second cutting member 32 is disposed to cooperate with the first cutting member 31 to cut sundries such as hair, the second cutting member 32 also passes through the first opening 11c to extend into the first mounting groove 11 a. Thereby, the second cutting member 32 and the first cutting member 31 can be made to cut the foreign matter such as the hair wound around the first roller brush 20 together.

In an embodiment, the first opening 11c is disposed near the suction port 11b, and the foreign matter such as hair cut by the first cutting member 31 on the first rolling brush 20 flows into the suction port 11b with the outside air flow in a direction consistent with the rotation direction of the first rolling brush 20. Thereby, it is possible to promote the entry of the sundries such as the cut hair into the suction port 11b more smoothly, so that the collection effect of the floor brush can be improved.

In one embodiment, referring to fig. 2 and 5, the housing 10 has a suction port 11b facing the first roller brush 20, and the floor brush includes a second roller brush 50 rotatably disposed in the housing 10 on a side of the first roller brush 20 facing away from the suction port 11b. That is, the floor brush can be provided with two rolling brushes to improve the dust removing effect of the product. And, the suction port 11b faces the first roller brush 20, so that the cut hair and other impurities can be conveniently introduced into the suction port 11b along with the airflow, and the cleaning effect on the floor brush can be improved.

In an embodiment, referring to fig. 2 and 3, the ground brush includes a second driving device 60, the second driving device 60 includes a second driving motor 61 and a second transmission assembly 62, and the second driving motor 61 drives the second transmission assembly 62 to rotate the first rolling brush 20 and the second rolling brush 50.

Specifically, the second driving motor 61 directly drives the second transmission assembly 62, and the second transmission assembly 62 drives the first rolling brush 20 and the second rolling brush 50 to rotate respectively. Thereby, the first and second rolling brushes 20 and 50 can be simultaneously driven to rotate by one second driving motor 61.

It should be noted that the second driving device 60 may cooperate with the first driving device 40, that is, the two driving devices operate simultaneously, so that the shearing effect of the shearing assembly 30 is better.

The second transmission assembly 62 may be a pulley assembly or may be driven by other arrangements.

In addition, the second driving motor 61 may also adopt other driving methods.

Illustratively, the second driving motor 61 is in driving connection with the first rolling brush 20, the second transmission assembly 62 is in driving connection with the first rolling brush 20 and the second rolling brush 50 respectively, and the second driving motor 61 drives the first rolling brush 20 to rotate so that the second transmission assembly 62 drives the second rolling brush 50 to rotate. That is, the second driving motor 61 directly drives the first rolling brush 20 to rotate, and the first rolling brush 20 drives the second rolling brush 50 to rotate through the second transmission assembly 62.

The first rolling brush 20 and the second rolling brush 50 rotate in the same direction, so that the cleaner can be moved conveniently.

Further, although the first and second rolling brushes 20 and 50 are rotated in synchronization, the rotation speeds thereof may be set to be the same or may be set to be different. For example, the rotation speed of the first roll brush 20 is 3500 to 4500 rpm, and the rotation speed of the second roll brush 50 is 1500 to 2000 rpm.

In one embodiment, the first rolling brush 20 has a first accommodating cavity and a second opening communicated with the first accommodating cavity, the second opening is located at one axial end of the first rolling brush 20, and the second driving motor 61 is connected with the casing 10 and extends into the first accommodating cavity from the second opening.

Specifically, the second driving motor 61 extends into the first accommodating cavity, so that the second driving motor 61 is built into the first rolling brush 20, the overall size of the ground brush can be reduced, and the design requirement of miniaturization of the ground brush is met. The second driving motor 61 is connected to the housing 10, and plays a role of stabilizing the second driving motor 61. The output shaft of the second driving motor 61 directly drives the first rolling brush 20, thereby rotating the first rolling brush 20.

Of course, the second driving motor 61 may also be disposed in the second rolling brush 50, where the second driving motor 61 is fixed on the housing 10 and extends into the second rolling brush 50 along the axial direction, so that the second driving motor 61 may directly drive the second rolling brush 50 to rotate, and the second rolling brush 50 drives the first rolling brush 20 to rotate through the second transmission assembly 62.

In addition, the second driving motor 61 may be further disposed in the housing 10 at a side of the first rolling brush 20 facing away from the second rolling brush 50, thereby facilitating heat dissipation of the second driving motor 61 to improve stability of the cleaner in a long-time operating state.

It should be noted that the specific types of the first and second rolling brushes 20 and 50 may be determined as needed. For example, the first roller brush is a flocked roller brush, and the second roller brush 50 is a lint roller brush. Therefore, the dust collector can clean floors or carpets, and the aim of one brush with multiple purposes is fulfilled.

In one embodiment, referring to fig. 2, the bristles 22 of the bristle rolling brush are wound around the circumference of the barrel 21 and extend along the axis of the barrel 21 to form a 360 ° rotational pitch structure. Thus, by reasonably arranging the bristles 22, the cleaning effect of the bristle rolling brush can be improved.

In addition, the specific size of the bristle rolling brush can be determined according to the specific structure of the ground brush, for example, the diameter of the barrel 21 of the bristle rolling brush is between 40mm and 60mm, and the length of the bristle 22 is between 7mm and 10 mm.

In one embodiment, referring to fig. 6, the housing 10 includes a second accommodating cavity 10b having a front opening 10c and a bottom air inlet 10d, the ground brush includes a sealing member 70 disposed at a peripheral side of the bottom air inlet 10d, and the second rolling brush 50 is disposed at the front opening 10c and cooperates with the sealing member 70 to seal an outer periphery of the bottom air inlet 10 d.

That is, the front end of the bottom air intake 10d is sealed by the second rolling brush 50, and the other sides of the bottom air intake 10d in the circumferential direction are sealed by the sealing member 70, whereby the tightness of the second accommodation chamber 10b in the circumferential direction can be ensured to raise the vacuum degree of the floor brush, thereby improving the cleaning effect of the floor brush on the foreign matter.

It should be noted that, the sealing member 70 and the second rolling brush 50 seal the circumferential direction of the bottom air inlet 10d, and do not affect the dust collection and air inlet effect of the bottom air inlet 10 d. In addition, the kind of the seal 70 is not limited, and for example, the seal 70 is a lint.

In a specific embodiment, the gap between the second rolling brush 50 and the area of the housing 10 located at the top of the second rolling brush 50 is 0, and the bottom side of the second rolling brush 50 extends out of the front end opening 10c along the radial direction, so that the second rolling brush 50 can be closely attached to the ground in the working state of the ground brush, so as to further enhance the sealing effect of the second accommodating cavity 10b along the circumferential direction.

The distance that the second rolling brush 50 extends out of the front end opening 10c toward the bottom side may be 2mm to 3mm, or may be set according to practical situations.

In an embodiment, referring to fig. 5, the housing 10 has a second mounting groove 11d, the lint rolling brush is disposed in the second mounting groove 11d, and a portion of a groove wall of the second mounting groove 11d protrudes toward a direction close to the lint rolling brush to form a plurality of spaced comb teeth 111, and the comb teeth 111 are close to the lint rolling brush. Thereby, the comb teeth 111 can clean dust and foreign matter adhering to the lint roller brush, so that the peeled dust and foreign matter can flow into the suction port 11b with the airflow.

The comb teeth 111 are close to the lint rolling brush, which means that the comb teeth 111 may be close to the lint rolling brush but not contact with the lint rolling brush, or the comb teeth 111 may contact with and interfere with the lint rolling brush. It should be noted that, the contact and interference between the comb teeth 111 and the lint rolling brush can improve the cleaning effect of the comb teeth 111 on the lint rolling brush, and the specific depth of the comb teeth extending into the lint rolling brush may be greater than or equal to 0.5mm and less than or equal to 1mm. The penetration depth is controlled in the range, so that the lint rolling brush can be cleaned well and can not be prevented from rotating.

In an embodiment, referring to fig. 5, the housing 10 includes a rib 12, the rib 12 is located on a side of the first roller brush 20 facing away from the second roller brush 50, and the rib 12 is spaced from a sidewall of the housing 10 provided with the suction port 11b and avoids the suction port 11b, so that a buffer 10a is formed at the spacing.

Specifically, the rib 12 is located between the side wall of the housing 10 having the suction port 11b and the second roller brush 50, and a buffer zone 10a is formed at the interval between the rib 12 and the side wall, and the buffer zone 10a communicates with the suction port 11b, so that the buffer effect can be achieved, and therefore, the problem that the suction port 11b is blocked by impurities such as hair cut by the cutting assembly 30 on the first roller brush 20 due to the fact that the suction port 11b is too close to the first roller brush 20 can be avoided.

The rib 12 avoids the suction port 11b, that is, the rib 12 is not provided at the suction port 11b, and may be a notch located at the suction port 11b, so that the airflow passing through the first rolling brush 20 can pass through conveniently, however, other specific structures may be adopted to avoid the suction port 11b, such as a plurality of ribs 12 arranged at intervals to avoid the suction port 11b at intervals.
