Example 1
Referring to fig. 1, the present embodiment provides a roller brush, which includes a body 22, the body 22 has an inner wall 24 and an outer wall 26, the body 22 has a through slot 28 penetrating the inner wall 24 and the outer wall 26, and the inner wall 24 encloses a receiving space 30.
The inner wall 24 encloses a receiving space 30 for receiving other components, thereby making full use of the space of the body 22. The outer wall 26 forms a cleaning portion, or the outer wall 26 is provided with an additional cleaning portion, so that the cleaning portion is driven to clean when the body 22 rotates, for example, the outer wall 26 can be covered with a cleaning cloth, cleaning of the ground can be achieved through contact of the cleaning cloth with the ground, and replacement of the cleaning cloth is facilitated, further, the cleaning cloth can be a wet mop, so that wet mopping of the ground can be achieved, and it should be noted that the through groove 28 is exposed when the cleaning cloth is covered.
The through slot 28 through the inner wall 24 and the outer wall 26 may allow at least a portion of other components received in the receiving space 30 to pass through the through slot 28.
The number of the through grooves 28 is at least two, and at least two through grooves 28 are arranged at intervals in the circumferential direction. The circumferentially spaced through slots 28 allow other components to be selectively and conveniently inserted through the through slots 28, i.e., other components can be selectively inserted through any one of the through slots 28, which makes the operation easier.
In this embodiment, the through slots 28 include a first slot 32 and a second slot 34 that are connected, with the first slot 32 and the second slot 34 being disposed at an angle. Specifically, the first slot 32 and the second slot 34 are communicated with each other at an obtuse angle, and compared with the straight through slot 28, the through slot 28 of the present embodiment has a longer extending length, so that more parts of other components can protrude out of the through slot 28. It will be appreciated by those skilled in the art that the through groove 28 may extend spirally along the circumference of the body 22, and the through groove 28 may be a plurality of through holes, and any solution similar or identical to the embodiment is covered by the protection scope of the present invention.
Example 2
Referring to fig. 2, the present embodiment provides a rolling brush assembly 36, wherein the rolling brush assembly 36 includes the rolling brush described in embodiment 1, and for convenience of the following description, the rolling brush of embodiment 1 is defined as the first rolling brush 20. The brush roll assembly 36 further includes a second brush roll 38, the second brush roll 38 including a second body 40 and a second cleaning portion 42 connected thereto. The second cleaning portion 42 may be a bristle or an integrally formed rubber strip, and so on, which will not be described again, and all the embodiments that are the same as or similar to the embodiments are covered in the protection scope of the present invention.
Referring to fig. 2 and 3, the rolling brush assembly 36 has a first working state and a second working state, in the first working state shown in the left side of fig. 3, the second rolling brush 38 is accommodated in the accommodating space 30 formed by the first rolling brush 20, and only the first rolling brush 20 is in the working state at this time, so as to perform a cleaning task; in a second operating position, which is shown on the right in fig. 3, the second cleaning section 42 of the second roller brush 38 extends at least partially through the through-slot 28 and beyond the outer wall 26 of the first roller brush 20, with the second roller brush 38 in the operating position, performing a cleaning task.
That is, the outer diameter of the second rolling brush 38 is smaller than the diameter of the inner wall 24 of the first rolling brush 20, in the first working state, the second rolling brush 38 is accommodated in the accommodating space 30, the first rolling brush 20 can contact the surface to be cleaned, and the surface to be cleaned can be cleaned by the cleaning portion of the first rolling brush 20 (i.e. the outer wall of the first rolling brush 20); in the second operating state, the second cleaning portion 42 extends at least partially through the through slot 28 and beyond the outer wall 26, and the second cleaning portion 42 can contact the surface to be cleaned, and the second roller brush 38 can be used to clean the surface to be cleaned, and the first roller brush 20 does not contact the surface to be cleaned.
So set up, first round brush 20 and second round brush 38 can divide the labour, for example, first round brush 20 realizes the function that wets and drags, and second round brush 38 realizes the function that cleans, and a round brush subassembly 36 can realize the clean function of two kinds of differences, satisfies different clean needs, very big promotion user experience.
Moreover, when different working states are switched, only the first rolling brush 20 and the second rolling brush 38 need to move relatively in the radial direction, so that the second cleaning part 42 retracts into the accommodating space 30, or the second cleaning part 42 penetrates through the through groove 28 and extends out of the accommodating space 30, the whole rolling brush does not need to be dismounted, and the switching operation is very simple.
In the first operating state, the second rolling brush 38 is entirely accommodated in the accommodating space 30 of the first rolling brush 20, the first rolling brush 20 is driven to rotate to realize the cleaning function, the second rolling brush 38 preferably rotates synchronously with the first rolling brush 20, and the second rolling brush 38 may not rotate as long as the second rolling brush 38 is held in the accommodating space 30 of the first rolling brush 20.
In the second working state, the second cleaning portion 42 of the second rolling brush 38 at least partially passes through the through groove 28 and extends out of the outer wall 26 of the first rolling brush 20, and the first rolling brush 20 and the second rolling brush 38 rotate synchronously, so that the first rolling brush 20 and the second rolling brush 38 are relatively static in the circumferential direction, and therefore, the first rolling brush 20 does not influence the normal work of the second rolling brush 38, and the design is quite reasonable.
For convenience of subsequent description, the rotation axis of the first rolling brush 20 is defined as a first axis, the rotation axis of the second rolling brush 38 is defined as a second axis, the first axis and the second axis are parallel, the two axes are parallel, the structure is regular, and the rolling brush assembly 36 can be miniaturized in structure and is more convenient to use.
The relative movement of the first axis and the second axis along the radial direction can switch the rolling brush assembly 36 between the first working state and the second working state, and the switching operation is very simple. For example, the first roller brush 20 is held stationary and the cleaning portion of the second roller brush 38 is moved radially outwardly in alignment with the through slot 28, thereby switching the roller brush assembly 36 from the first operating condition to the second operating condition. Of course, it can be understood by those skilled in the art that the second rolling brush 38 remains stationary, the first rolling brush 20 may move radially inward, or the first rolling brush 20 and the second rolling brush 38 may move radially relative to each other at the same time to switch between the first working state and the second working state, and so on, which will not be described again, and all the embodiments that are the same as or similar to the present embodiment are included in the protection scope of the present invention.
Referring back to fig. 1 and 2, as mentioned above, the number of the through slots 28 is at least two, and at least two through slots 28 are circumferentially spaced. Preferably, the number of the second cleaning portions 42 of the second rolling brush 38 is at least two, and at least two second cleaning portions 42 are circumferentially spaced on the second body 40. Referring to fig. 2 and 3, after the first operating state is switched to the second operating state, only a portion of the second cleaning portion 42 of the second rolling brush 38 extends out of the through slot 28 to clean the surface to be cleaned, and the other portion of the cleaning portion is accommodated in the accommodating space 30. The part of the cleaning portion that is frequently used may be worn out by long-term use, and therefore, the relative angle of the second roller brush 38 to the first roller brush 20 in the rotation direction may be periodically changed to periodically protrude different second cleaning portions 42 through the slot 28 to clean the surface to be cleaned, so that the cleaning effect of the second roller brush 38 is longer in service life, and illustratively, in the same cleaning task, the different second cleaning portions 42 may be adjusted at a specified frequency, for example, 5min,10min, etc., without limitation, to perform the cleaning task. In another example, it is also possible to sequentially adjust the different second cleaning portions 42 to perform the cleaning tasks in order of the cleaning tasks.
As mentioned above, in the first operation mode, the first rolling brush 20 rotates, and the second rolling brush 38 may rotate synchronously with the first rolling brush 20 or may not move. If the second rolling brush 38 and the first rolling brush 20 always rotate synchronously, relative rotation does not exist between the two, and radial movement switching is easier; if the second rolling brush 38 is stationary and only the first rolling brush 20 rotates in the first mode, it is required to confirm that the second cleaning portion 42 of the second rolling brush 38 is aligned with the through slot 28 during switching, and relatively speaking, an additional confirmation and adjustment process is required during switching, but the energy consumption of the second rolling brush 38 can be reduced during the operation of the first rolling brush 20, which is more environment-friendly.
Example 3
Referring to fig. 4, the present embodiment provides a cleaning apparatus, which includes the rolling brush assembly 36 of embodiment 2, and further includes a driving device for driving the rolling brush assembly 36 to switch between a first working state and a second working state. Therefore, the switching of the two working states is realized through the driving device, manual operation is not needed, and the user experience can be improved.
The driving means includes a first driving means 44 for driving the first roll brush 20, and a second driving means 46 for driving the second roll brush 38, and the first driving means 44 and the second driving means 46 are spaced apart. That is to say, the driving devices of the first rolling brush 20 and the second rolling brush 38 are separately arranged, which not only makes the structures of the two driving devices simpler and the driving more reliable, but also facilitates separate control, and meets different control requirements, for example, in the first working state, the first rolling brush 20 needs to rotate, and the second rolling brush 38 can rotate or be stationary, and the control device separately arranged makes the control of the whole cleaning device simpler.
The first drive device 44 and the second drive device 46 are respectively provided at both end sides of the roll brush assembly 36. The two driving devices are respectively arranged at the two end sides of the rolling brush assembly 36, so that mutual interference is avoided, and the structural layout of the whole cleaning device is more regular and balanced, so that the cleaning device is more reliable to use.
The first drive means 44 and the second drive means 46 are of identical construction. The two driving devices have the same structure, the design is simpler, and the design, die sinking, assembly and other costs can be reduced.
The first driving device 44 will be described below as an example.
Referring to fig. 4 and 5, the first driving device 44 includes a motor (not shown), a first rotary driving mechanism 48 driven by the motor, and the first rotary driving mechanism 48 drives the first rolling brush 20 to rotate; the first driving device 44 further includes a second rotary driving mechanism 50 driven by a motor, and a reciprocating driving mechanism 52 clutched to the second rotary driving mechanism 50, wherein when the reciprocating driving mechanism 52 is connected to the second rotary driving mechanism 50, the reciprocating driving mechanism 52 drives the first rotary driving mechanism 48 to move linearly.
That is, the first driving device 44 can not only drive the first rolling brush 20 to rotate to perform its cleaning function, but also drive the first rolling brush 20 to linearly move, so that the first rolling brush 20 moves relative to the second rolling brush 38 in the radial direction, thereby realizing the switching between two working states, and improving the efficiency and reliability of switching before different working modes.
The second rotary drive mechanism 50 is clutched to the reciprocating drive mechanism 52, i.e., both have a disengaged state and an engaged state. In the separated state, the second rotary driving mechanism 50 is spaced apart from the reciprocating driving mechanism 52, and the second rotary driving mechanism 50 cannot drive the reciprocating driving mechanism 52, so that the reciprocating driving mechanism 52 is prevented from affecting the normal rotary cleaning function of the first rolling brush 20. In the engaged state, the second rotary driving mechanism 50 is engaged with the reciprocating driving mechanism 52 and enables the reciprocating driving mechanism 52 to drive the first rotary driving mechanism 48 to generate linear movement, so as to drive the whole first driving device 44 to linearly move, thereby realizing the switching between the two working states.
When the motor rotates around the first direction, the reciprocating driving mechanism 52 and the second rotary driving mechanism 50 are in a separated state; when the motor rotates in the second direction, the motor drives the second rotary drive mechanism 50 to approach the reciprocating drive mechanism 52, and the clutch state is switched to the engaged state. That is, switching between the engaged state and the disengaged state of the second rotary drive mechanism 50 and the reciprocating drive mechanism 52 can be achieved by switching the rotational direction of the motor, and the control is very simple.
Specifically, referring with emphasis to fig. 5, the first driving device 44 includes a center wheel 54 driven by a motor (not shown), and the motor drives the first and second rotary driving mechanisms 48 and 50 to rotate through the center wheel 54.
The first rotary drive mechanism 48 includes a first gear 56 engaged with the center wheel 54, and the first gear 56 rotates the first roller brush 20. The linkage mechanism between the first gear 56 and the first rolling brush 20 can be set as required, and is not described in detail.
The second rotary drive mechanism 50 includes a second gear 58 meshing with the center gear 54, a helical gear 60 disposed coaxially with the second gear 58, and a ratchet 62 meshing with the helical gear 60. When the bevel gear 60 rotates along the first direction, the bevel gear 60 cannot drive the ratchet 62 to generate linear movement along the axial direction; the helical gear 60 is rotated in the second direction to drive the ratchet 62 to move linearly in its axial direction. The ratchet 62 is provided at one end surface thereof with a first clutch member 64 which is in clutching connection with the reciprocating drive mechanism 52.
Referring to fig. 5 and 6, the first clutch member 64 is ramp-shaped and includes a circumferentially extending spiral surface 66 and a vertical surface 68 connected to the spiral surface 66 and perpendicular to the end surface of the ratchet wheel 62. The helical surface 66 facilitates engagement of the first clutch member 64 with the reciprocating drive mechanism 52 during rotation, and the vertical surface 68 provides a circumferentially fixed engagement of the ratchet wheel 62 with the reciprocating drive mechanism 52, which is well suited for design. The number of the first clutch members 64 is at least two, and the at least two first clutch members 64 are uniformly arranged at intervals along the circumferential direction, so that the clamping is more reliable.
The reciprocating drive mechanism 52 includes a moving member 70 and a fixed member 72 eccentrically drivingly connected to the moving member 70. The end surface of the moving member 70 facing the ratchet wheel 62 is provided with the second clutch members 74, and the shapes and the number of the second clutch members 74 are the same as those of the first clutch members 64, so that the second clutch members 74 can be conveniently and reliably engaged with the first clutch members 64. Thus, when the motor output rotates in the second direction, the helical gear 60 drives the ratchet gear 62 to move axially, thereby engaging the first clutch member 64 with the second clutch member 74 and the second rotary drive mechanism 50 drives the reciprocating drive mechanism 52.
The end face of the mover 70 remote from the ratchet 62 is provided with an eccentric pin 76. The fixing member 72 comprises a fixedly connected, preferably integrally formed, mating portion 78 and a rod portion 80, the mating portion 78 being provided with a kidney slot 82 for cooperation with the eccentric pin 76, the rod portion 80 extending lengthwise, the kidney slot 82 extending in a direction perpendicular to the direction of extension of the rod portion 80. The stem portion 80 is fixed relative to the housing of the cleaning device, and thus the stem portion 80 and the mating portion 78 are relatively fixed. When the eccentric pin 76 slides in the kidney-shaped slot 82, the engaged moving member 70, the second rotary driving mechanism 50, the center wheel 54 and the first rotary driving mechanism 48 are driven to integrally generate linear movement in the extending direction of the kidney-shaped slot 82, so that the first rolling brush 20 generates linear movement in the radial direction thereof, and the rolling brush assembly 36 is convenient to switch between the first working state and the second working state.
As mentioned above, the structure and operation principle of the second driving device 46 are the same as those of the first driving device 44, and thus the description thereof is omitted.
The operation of the cleaning device of the present embodiment is described below.
The first working state:
when the motor output shaft of the first drive device 44 outputs rotation in the first direction, the center wheel 54 connected to the motor drives the first and second rotary drive mechanisms 48, 50 to rotate. Although the first rotary driving mechanism 48 drives the first rolling brush 20 to rotate for cleaning, the second rotary driving mechanism 50 also rotates, but the helical gear 60 cannot drive the ratchet 62 to move axially, the second rotary driving mechanism 50 is spaced from the reciprocating driving mechanism 52, the reciprocating driving mechanism 52 drives the output shaft of the first rolling brush 20 to move radially, the radial relative position of the first rolling brush 20 and the second rolling brush 38 does not change, and the working state of the rolling brush assembly 36 does not switch.
At this time, the second rolling brush 38 is located in the receiving space 30 of the first rolling brush 20, and if the second rolling brush 38 is stationary, the second motor of the second driving device 46 is turned off, and the second driving device 46 does not operate. If the second rolling brush 38 is rotated in synchronization with the first rolling brush 20, the second motor of the second driving device 46 is started, and since the structure and principle of the second driving device 46 are the same as those of the first driving device 44, the second driving device 46 drives such that the second rolling brush 38 is rotated, but the relative positions of the second rolling brush 38 and the first rolling brush 20 are not changed, and the operation state of the rolling brush assembly 36 is not switched.
Switching:
the output shaft of the motor of the first drive device 44 outputs rotation in the second direction, and the center wheel 54 connected to the motor drives the first and second rotary drive mechanisms 48, 50 to rotate in opposite directions. The first rotary drive mechanism 48 drives the first rolling brush 20 to rotate reversely, the helical gear 60 of the second rotary drive mechanism 50 drives the ratchet gear 62 to rotate reversely and move axially, the first clutch 64 is engaged with the second clutch 74, so that the ratchet gear 62 of the second rotary drive mechanism 50 is engaged with the moving member 70 of the reciprocating drive mechanism 52, the eccentric pin 76 of the moving member 70 slides in the kidney-shaped groove 82, the belt second rotary drive mechanism 50, the center wheel 54 and the first rotary drive mechanism 48 move in the extending direction of the kidney-shaped groove 82, so that the first rolling brush 20 moves radially relative to the second rolling brush 38, and the second cleaning portion 42 of the second rolling brush 38 at least partially passes through the through groove 28 of the first rolling brush 20 and extends out of the outer wall 26 of the first rolling brush 20, and is switched from the first working state to the second working state.
In the switching process, the first rolling brush 20 can rotate reversely, so that the first rolling brush 20 rotates and moves radially, and the most accurate and rapid switching method is that the first rolling brush 20 and the second rolling brush 38 rotate synchronously in the first working state and the second working state, so that the first rolling brush 20 and the second rolling brush 38 do not have relative position change in the circumferential direction, and cleaning of the surface to be cleaned can be accurately and reliably realized when the second rolling brush 38 works.
Of course, if the second rolling brush 38 and the first rolling brush 20 do not rotate synchronously before the switching, the rotation position of the first rolling brush 20 and/or the second rolling brush 38 is/are properly adjusted before the switching, and the first driving device 44 and the second driving device 46 can be driven to rotate synchronously and reversely after the second cleaning portion 42 of the second rolling brush 38 is aligned with the through slot 28, so that the switching can be realized.
Furthermore, because the second cleaning portion 42 has a certain elasticity, the first rolling brush 20 (or the second rolling brush 38) can be directly driven by the first driving device 44 (or the second driving device 46) to rotate reversely and simultaneously move radially, so that the first rolling brush 20 and the second rolling brush 38 can move relatively in the radial direction; then, the rotational position of the second roller brush 38 (or the first roller brush 20) is slightly adjusted so that the second cleaning portion 42 is aligned with the through groove 28 and at least partially passes through the through groove 28.
In summary, it is within the scope of the present invention to move the first rolling brush 20 and/or the second rolling brush 38 relative to each other in the radial direction by the first driving device 44 and/or the second driving device 46, and finally to make the second cleaning portion 42 of the second rolling brush 38 at least partially pass through the through groove 28 by properly adjusting the rotational position of the first rolling brush 20 and/or the second rolling brush 38, if necessary.
The second working state:
the motor of the first driving device 44 outputs rotation in the first direction to drive the first roll brush 20 to rotate without producing relative movement in the radial direction, and the motor of the second driving device 46 outputs rotation in the first direction to drive the second roll brush 38 to rotate without producing relative movement in the radial direction; the first rolling brush 20 is rotated but is away from the surface to be cleaned, and the second cleaning portion 42 of the second rolling brush 38 is brought into contact with the surface to be cleaned to clean the surface to be cleaned.
Therefore, it can be seen that the cleaning device of the present embodiment not only can switch the rolling brush assembly 36 between the first working state and the second working state, so as to selectively use the first rolling brush 20 or the second rolling brush 38 to clean the surface to be cleaned, but also the motor rotates forward to drive the rolling brush assembly 36 to work, and rotates backward to realize the switching of the modes, so that the operation is very simple.
Example 4
This embodiment provides a control method of the cleaning apparatus according to embodiment 3, including the steps of:
s1: receiving a cleaning instruction of a user;
s2: and controlling one of the first rolling brush and the second rolling brush to perform a cleaning task according to the cleaning instruction.
Preferably, the control method further includes the steps of:
s3: and after one of the first rolling brush and the second rolling brush is executed, controlling the other one of the first rolling brush and the second rolling brush to execute a cleaning task.
Specifically, the user sends a cleaning instruction through a key or voice control, and after receiving the cleaning instruction from the user, the motor outputs rotation in the first direction to drive the rolling brush assembly 36 to be in the first working state or the second working state, that is, the first rolling brush or the second rolling brush is made to execute a cleaning task according to the instruction.
If the user gives a command to change the working roller brush (i.e., the roller brush for performing the cleaning task) by means of a button or voice control, etc., the control motor outputs a rotation in the second direction to drive the first roller brush 20 and the second roller brush 38 of the roller brush assembly 36 to move in the radial direction, so as to prepare for changing the working roller brush.
Subsequently, the motor outputs the motion in the first direction to drive the rolling brush assembly 36 to be in the second working state or the first working state, that is, after the working rolling brush is switched in place, the motor continues to output the rotation in the first direction, so that the rolling brush assembly 36 can use the switched working rolling brush to perform the cleaning task. The specific driving of the second operating state and the first operating state is the same as that described above, and is not described again.
Therefore, the control method can control the working state of the rolling brush component 36 and the switching of the working state only by changing the rotation direction of the motor after receiving the instruction of the user, and the control is very simple.
It is to be understood that the above-described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
