Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.
The present application provides a rolling brush, and the structure and the working principle of the rolling brush of the present application are described below by using two specific embodiments.
As shown in fig. 1, which is a schematic structural diagram of a first rolling brush provided in the present application, the rolling brush includes: the cleaning device comprises an annular belt brush 1 and two roller bodies, wherein the roller bodies comprise a first roller body 201 and a second roller body 202, the first roller body 201 and the second roller body 202 are driven to rotate around the respective rotation axes thereof, the rotation axes of the first roller body 201 and the second roller body 202 are parallel to each other, and in practice, the rotation axes of the first roller body 201 and the second roller body 202 of the roller brush are set to be parallel to each other, so that the first roller body 201 and the second roller body 202 can be kept in surface contact with a cleaned surface through the annular belt brush 1 all the time; in the connection mode of the annular belt brush 1 and the first roller body 201 and the second roller body 202, the annular belt brush 1 is sleeved on the outer surfaces of the first roller body 201 and the second roller body 202, and the first roller body 201 and the second roller body 202 rotate to drive the annular belt brush 1 to move annularly, so that the outer surface of the annular belt brush 1 is kept in surface contact with a cleaned surface.
Specifically, in the connection manner of the first roller body 201, the second roller body 202 and the endless belt brush 1, the first roller body 201 and the second roller body 202 are respectively distributed at two ends of the endless belt brush 1, and when the entire roller brush rotates between the first roller body 201 and the second roller body 202, the outer surface of the endless belt brush 1 is in surface contact with the surface 4 to be cleaned, thereby achieving the cleaning effect. Wherein, in the connection device of the whole first roller body 201, the whole second roller body 202 and the annular belt brush 1, the motor provides the power for the movement of the whole connection device. The manner in which the motor is used to power the entire linkage is varied and is described in the following description by way of example with two motors providing power to the entire linkage.
The motor has multiple modes for whole connecting device provides power: for example, a motor may be used to power the whole connecting device, or a motor may be provided for each roller body, and a plurality of motors drive the respective roller bodies to rotate synchronously and simultaneously. The former can adopt a mechanical transmission mode, and the latter can adopt a motor control mode.
When one motor is adopted to provide motion power for the whole connecting device, the motion power can be provided for the whole connecting device in a mechanical transmission mode. For example, a motor may be disposed at the middle of the roller body, a pinion gear is fixed on the output shaft of the motor, and the rotating shaft of each roller body is coaxially fixed to a large gear engaged with the pinion gear of the output shaft of the motor, so that the motion can be transmitted to a plurality of roller bodies by one motor, and the same rotating speed and the same rotating direction of each roller body can be ensured. The mechanical mechanism can realize the effect of reducing the rotating speed of the motor to the rotating speed required by the roller body through gear engagement.
When a plurality of motors are adopted to provide motion power for the whole connecting device, the motion power can be provided for the whole connecting device in a motor control mode. Namely, each roller body is independently and correspondingly provided with a motor, and the motors can output the same steering direction and rotating speed through the rotating speed control circuit of the motors. For example, the control of each motor can be realized by adopting a general motor servo control principle, and the same rotating speed instruction is provided for the servo control units of each motor, so that the consistent rotating speed and steering can be obtained. If the control of the rotational speed of the roller bodies needs to be very precise, a differential control unit can also be provided to automatically adjust when a difference in rotational speed between the roller bodies is detected.
The above two specific implementation manners of providing power for the whole connecting device by the motors are already provided with mature schemes in the prior art, and are not described herein again.
In the preferred embodiment of the present application, the first roller body 201 and the second roller body 202 are cylindrical roller bodies as shown in fig. 1, and a rotating shaft 201-1 and a rotating shaft 202-1 are respectively installed at the axial centers of the first roller body 201 and the second roller body 202, respectively, when the roll brush of the present application is installed on a vacuum cleaner, the first roller body 201 and the second roller body 202 are respectively installed on the body of the vacuum cleaner through the rotating shaft 201-1 of the first roller body 201 and the rotating shaft 202-1 of the second roller body 202, and the first roller body 201 and the second roller body 202 can rotate along with the rotation of the rotating shaft 201-1 and the rotating shaft 202-1; the annular belt brush 1 is sleeved on the outer diameter surfaces of the first roller body 201 and the second roller body 202 of the cylindrical structure, and the first roller body 201 and the second roller body 202 drive the annular belt brush 1 to move annularly when rotating. At this time, the first roller body 201 and the second roller body 202 are connected to the motor through respective lines, and after the motor is turned on, the first roller body 201 and the second roller body 202 synchronously rotate in the same direction.
In the above-mentioned manner of driving the endless belt brush 1 to move circularly after the first roller body 201 and the second roller body 202 rotate, in practice, the endless belt brush 1 may be sleeved on the outer diameter surfaces of the first roller body 201 and the second roller body 202 to move the endless belt brush 1 in various manners, and the following two movement manners are explained:
the first movement mode of the endless belt brush 1 sleeved on the outer diameter surfaces of the first roller body 201 and the second roller body 202 is: the inner surface of the annular belt brush 1 is sleeved on the outer surfaces of the outer diameters of the first roller body 201 and the second roller body 202 by adopting a first roller body 201 and a second roller body 202 which comprise gear structures and the annular belt brush 1 which comprises a notch meshed with the gear structures.
Specifically, gear structures are arranged on the outer surfaces of the outer diameters of the first roller body 201 and the second roller body 202, and correspondingly, notches corresponding to the gears are arranged on the inner surface of the annular belt brush 1, that is, the gears on the outer surfaces of the outer diameters mesh with the notches on the inner surface of the annular belt brush 1 when the first roller body 201 and the second roller body 202 rotate, so that the annular belt brush 1 is driven to move annularly around the first roller body 201 and the second roller body 202. It can be understood that the size of the notches on the inner surface of the annular brush 1 is matched with the size of the gears on the outer surfaces of the outer diameters of the first roller body 201 and the second roller body 202, that is, the gears are just meshed with the notches, so that the roller bodies on which the gears are arranged can drive the annular brush on which the notches are arranged to move circularly when rotating.
The second movement mode that the annular belt brush 1 is sleeved on the outer diameter surfaces of the first roller body 201 and the second roller body 202 is as follows: the first roller body 201 and the second roller body 202 with the external surfaces of the external diameters being non-smooth surfaces and the annular belt brush 1 with the internal surfaces being non-smooth surfaces are adopted, and the internal surface of the annular belt brush 1 is sleeved on the external surfaces of the external diameters of the first roller body 201 and the second roller body 202.
Specifically, the outer surfaces of the outer diameters of the first roller body 201 and the second roller body 202 are made of non-smooth surface materials, correspondingly, the inner surface of the annular belt brush 1 is also made of non-smooth surface materials, namely, friction exists between the non-smooth outer surface of the outer diameter and the non-smooth inner surface of the annular belt brush 1 when the first roller body 201 and the second roller body 202 rotate, so that the first roller body 201 and the second roller body 202 drive the endless belt brush 1 to move circularly when rotating, it can be understood that the friction between the non-smooth outer surfaces of the outer diameters of the first roller body 201 and the second roller body 202 and the non-smooth inner surface of the endless belt brush 1 can drive the endless belt brush 1 to move circularly, the specific material of the outer surface of the inner surface of the endless belt brush 1 on the outer diameter surface of the first roller body 201 and the second roller body 202 is not limited.
In the whole movement process of the device, the first roller body 201 and the second roller body 202 have the same movement direction, specifically, taking the second movement mode that the annular belt brush 1 is sleeved on the outer diameter surfaces of the first roller body 201 and the second roller body 202 as an example, when the first roller body 201 and the second roller body 202 rotate forward, the outer surfaces of the annular belt brush 1, the first roller body 201, the second roller body 202 and the annular belt brush 1 are all subjected to a friction force in the direction opposite to the rotation direction of the roller bodies, according to the principle of the friction force and the relative friction force, the inner surface parts of the annular belt brush 1, the first roller body 201 and the second roller body 202 are subjected to a friction force in the direction consistent with the rotation direction of the roller bodies, so as to realize that the annular belt brush 1 moves forward when the first roller body 201 and the second roller body 202 rotate forward, and the principle of the friction force and the relative friction force are adopted, the forward annular movement of the annular belt brush 1 is driven when the first roller body 201 and the second roller body 202 rotate forwards.
In the above process, if the first roller body 201 and the second roller body 202 rotate in different directions, the friction force between the first roller body 201 and the endless belt brush 1 and the friction force between the second roller body 202 and the endless belt brush 1 are caused to be opposite, so that the friction force of the first roller body 201 on the endless belt brush 1 and the friction force of the second roller body 202 on the endless belt brush 1 are caused to be opposite, even two friction forces are offset in value, so that the roller bodies cannot drive the endless belt brush 1 to move circularly, and therefore the rotation directions of the roller bodies must be the same.
In addition, the annular belt brush 1 is an annular closed structure as shown in fig. 1, and the outer surface of the annular belt brush is provided with bristles, the bristles are uniformly distributed on the outer surface of the annular belt brush 1, and when the annular belt brush 1 moves annularly, i.e. the rolling brush works, at least part of the bristles are always in contact with the surface 4 to be cleaned, so that the bristle part of the annular belt brush 1 is always in contact with the surface 4 to be cleaned, thereby achieving the cleaning effect, and simultaneously, the plane formed by the rotation axes of the first roller body 201 and the second roller body 202 is parallel to the surface 4 to be cleaned, i.e. the shape and the size of the first roller body 201 and the second roller body 202 are the same.
Since the brush bristles of at least a partial region of the annular belt brush 1 are always in contact with the surface 4 to be cleaned, the roller brush can achieve a cleaning effect, and in addition, other cleaning materials can be arranged on the outer surface of the annular belt brush 1, for example, a cleaning cloth can be arranged on the outer surface of the annular belt brush 1 for wiping after cleaning.
The round brush in this embodiment adopts the annular band brush to cup joint on two gyro wheel bodies, has increased the girth of annular band brush, consequently uses the round brush of this application to clean and is difficult for causing to twine the hair, in addition, has also increased the area of contact of annular band brush with by the cleaning surface when increasing the girth of annular band brush, consequently uses the round brush of this application to clean comparatively save time.
As shown in fig. 2, which is a schematic structural diagram of a second rolling brush provided by the present application, the rolling brush includes: the cleaning device comprises an annular belt brush 1 and three roller bodies, wherein the roller bodies comprise a first roller body 301, a second roller body 302 and a tensioning roller body 303, and in the embodiment, the tensioning degree of the annular belt brush 1 can be adjusted by the three roller bodies, so that the outer surface of the annular belt brush is kept in surface contact with a cleaned surface. In the daily use process of the roller brush, the annular belt brush 1 needs to make surface contact with the cleaned surface 4 to achieve the cleaning effect, and if the annular belt brush is in a non-tensioned state in the use process, the contact area between the annular belt brush 1 and the cleaned surface is small, and even the normal operation of the roller brush is affected, therefore, in the embodiment, three roller bodies, namely, the first roller body 301, the second roller body 302 and the tensioning roller body 303 are selected to adjust the annular belt brush 1 to the optimal tensioning degree so as to achieve the better cleaning effect.
In the whole rolling brush structure, the first roller body 301, the second roller body 302 and the tension roller body 303 are driven to rotate around the respective rotation axes, the rotation axes of the first roller body 301, the second roller body 302 and the tension roller body 303 are parallel to each other, and in practice, the rotation axes of the first roller body 301, the second roller body 302 and the tension roller body 303 of the rolling brush are set to be parallel to each other, so that the first roller body 301 and the second roller body 302 can be kept in surface contact with a cleaned surface through the annular belt brush 1 all the time; in the connection mode of the annular belt brush 1 and the first roller body 301, the second roller body 302 and the tensioning roller body 303, the annular belt brush 1 is sleeved on the outer surfaces of the first roller body 301, the second roller body 302 and the tensioning roller body 303, and the first roller body 301, the second roller body 302 and the tensioning roller body 303 rotate to drive the annular belt brush 1 to move circularly, so that the outer surface of the annular belt brush 1 is kept in surface contact with the cleaned surface 4.
Specifically, in the connection manner of the first roller body 301, the second roller body 302 and the tension roller body 303 with the endless belt brush 1, the first roller body 301, the second roller body 302 and the tension roller body 303 are respectively distributed at three vertexes of the endless belt brush 1, and the endless belt brush 1 has a triangular structure as shown in fig. 2, wherein one side of the triangular structure is in contact with the surface 4 to be cleaned, thereby achieving the cleaning effect. In the connection device of the entire first roller body 301, the second roller body 302 and the tension roller body 303 with the endless belt brush 1, the power for the movement of the entire connection device is provided by a motor. The power supply of the whole connecting device by the motor can be achieved in various ways, and the specific way of supplying the power of the roller body by the motor can be referred to the relevant description part of the first embodiment, and is not described herein again.
More specifically, in the preferred embodiment of the present application, the first roller body 301, the second roller body 302 and the tension roller body 303 are roller bodies having a cylindrical structure as shown in fig. 2, and the rotating shafts 301-1, 302-1 and 303-1 are respectively and correspondingly installed at the axial centers of the first roller body 301, the second roller body 302 and the tension roller body 303, when the roll brush of the present application is installed on the vacuum cleaner, the first roller body 301, the second roller body 302 and the tension roller body 303 are respectively installed on the body of the vacuum cleaner through the rotating shafts 301-1, 302-1 and 303-1, and the first roller body 301, the second roller body 302 and the tension roller body 303 can rotate along with the rotation of the rotating shafts 301-1, 302-1 and 303-1; the annular belt brush 1 is sleeved on the outer diameter surfaces of the first roller body 301, the second roller body 302 and the tensioning roller body 303 which are of cylindrical structures, and the first roller body 301, the second roller body 302 and the tensioning roller body 303 drive the annular belt brush 1 to move annularly when rotating. At this time, the first roller body 301, the second roller body 302 and the tension roller body 303 are connected to the motors through respective lines, and after the motors are turned on, the first roller body 301, the second roller body 302 and the tension roller body 303 are synchronously rotated in the same direction.
In the above-described manner of driving the endless belt brush 1 to move endlessly after the first roller body 301, the second roller body 302, and the tension roller body 303 rotate, the endless belt brush 1 may be moved by fitting the endless belt brush 1 to the outer diameter surfaces of the first roller body 301, the second roller body 302, and the tension roller body 303 in various manners, and two manners of movement will be described below:
the first movement mode in which the endless belt brush 1 is fitted to the outer diameter surfaces of the first roller body 301, the second roller body 302, and the tension roller body 303 is: the inner surface of the annular belt brush 1 is sleeved on the outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tensioning roller body 303 by adopting the first roller body 301, the second roller body 302 and the tensioning roller body 303 which comprise gear structures and the annular belt brush 1 which comprises notches meshed with the gear structures.
Specifically, gear structures are arranged on the outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tensioning roller body 303, and correspondingly, notches corresponding to the gears are arranged on the inner surface of the annular belt brush 1, namely, the first roller body 301, the second roller body 302 and the tensioning roller body 303 are meshed with the notches on the inner surface of the annular belt brush 1 through the gears on the outer surfaces of the outer diameters when rotating, so that the annular belt brush 1 is driven to move annularly around the first roller body 301, the second roller body 302 and the tensioning roller body 303. It can be understood that the gears on the outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tensioning roller body 303 are matched with the size of the notches on the inner surface of the annular belt brush 1, namely, the gears are just meshed with the notches, so that the roller bodies on which the gears are arranged can drive the annular belt brush on which the notches are arranged to move annularly when rotating.
The second movement mode in which the endless belt brush 1 is fitted to the outer diameter surfaces of the first roller body 301, the second roller body 302, and the tension roller body 303 is: the inner surface of the annular belt brush 1 is sleeved on the outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tensioning roller body 303 by adopting the first roller body 301, the second roller body 302 and the tensioning roller body 303 of which the outer surfaces are non-smooth surfaces and the annular belt brush 1 of which the inner surface is non-smooth surfaces.
Specifically, the outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tension roller body 303 are made of non-smooth surface materials, and correspondingly, the inner surface of the endless belt brush 1 is also made of non-smooth surface materials, namely, friction forces exist between the non-smooth outer surfaces of the outer diameters and the non-smooth inner surface of the endless belt brush 1 when the first roller body 301, the second roller body 302 and the tension roller body 303 rotate, so that the endless belt brush 1 is driven to move circularly when the first roller body 301, the second roller body 302 and the tension roller body 303 rotate, it can be understood that the friction forces between the non-smooth outer surfaces of the outer diameters of the first roller body 301, the second roller body 302 and the tension roller body 303 and the non-smooth inner surface of the endless belt brush 1 can drive the endless belt brush 1 to move circularly, namely, for the inner surface of the endless belt brush 1, the specific material of the outer surfaces of the first roller body 301, the second roller body 302, and the tension roller body 303 on the outer diameter surface is not limited.
In the whole device moving process, the first roller body 301, the second roller body 302 and the tension roller body 303 are in the same rotating direction, specifically, taking the second moving mode that the endless belt brush 1 is sleeved on the outer diameter surfaces of the first roller body 301, the second roller body 302 and the tension roller body 303 as an example, when the first roller body 301, the second roller body 302 and the tension roller body 303 rotate forwards, the outer surfaces of the first roller body 301, the second roller body 302 and the tension roller body 303 contacting the endless belt brush 1 are all subjected to a friction force in the direction opposite to the rotating direction of the roller bodies, and according to the principle of the friction force and the relative friction force, the inner surface parts of the endless belt brush 1 contacting the first roller body 301, the second roller body 302 and the tension roller body 303 are subjected to a friction force in the same direction as the moving direction of the roller bodies, so as to realize that the first roller body 301, the second roller body 302 and the tension roller body 303 simultaneously drive the endless belt brush 1 to move forwards, the principle adopts the principle of friction and relative friction, so that the first roller body 301, the second roller body 302 and the tensioning roller body 303 drive the annular belt brush 1 to move forwards circularly when rotating forwards.
In the above process, if the first roller body 301, the second roller body 302 and the tension roller body 303 move in different directions, the direction of the friction force applied to the endless belt brush 1 is not consistent, and the roller body cannot drive the endless belt brush 1 to move circularly, so the rotation directions of the roller bodies must be the same.
In addition, the endless belt brush 1 in this embodiment is also of an annular closed structure as shown in fig. 2, and bristles are arranged on the outer surface of the endless belt brush, the bristles are uniformly distributed on the outer surface of the endless belt brush 1, and when the endless belt brush 1 moves circularly, i.e., when the roller brush works, at least part of the bristles are in constant contact with the surface 4 to be cleaned, so that the bristles of the endless belt brush 1 are in constant contact with the surface 4 to be cleaned, thereby achieving the cleaning effect, and simultaneously, the plane formed by the rotation axes of the first roller body 301 and the second roller body 302 is parallel to the surface 4 to be cleaned, i.e., the shape and size of the first roller body 301 and the second roller body 302 are the same.
Since the brush bristles of at least a partial region of the annular belt brush 1 are always in contact with the surface 4 to be cleaned, the roller brush can achieve a cleaning effect, and in addition, other cleaning materials can be arranged on the outer surface of the annular belt brush 1, for example, a cleaning cloth can be arranged on the outer surface of the annular belt brush 1 for wiping after cleaning.
The round brush in this embodiment adopts the annular band brush to cup joint on three gyro wheel bodies, has increased the girth of annular band brush, consequently uses the round brush of this application to clean and is difficult for causing to twine the hair, in addition, has also increased the area of contact of annular band brush with by the cleaning surface when increasing the girth of annular band brush, consequently uses the round brush of this application to clean comparatively save time.
