Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning device, in particular, discloses a non-linear propulsion floor cleaning device.BACKGROUND

[0002] A floor cleaning brush of the current hand-held floor cleaning device cleans the floor through two brush plates rotating in opposite directions and arranged horizontally. The difference between the sum of front frictional forces and the sum of rear frictional forces are controlled by an inclination angle of the brush plates to provide forward power for the floor cleaning device. In the conventional technique of cleaning the floor using plate brushes, two plate brushes rotating in opposite directions are applied. In order to avoid the damage to the floor caused by the collision of the plate brushes, or the mutual damage between the plate brushes, a certain gap is arranged between the two plate brushes rotating in opposite directions. This gap may cause the plate brushes to be unable to completely cover every part of the floor during actual use. Therefore, during the movement, the area between the two plate brushes has low cleaning efficiency, and there may be cases of unclean cleaning, which affects user experience.SUMMARY

[0003] An object of the present application is to provide a non-linear propulsion floor cleaning device, to address the shortcomings and deficiencies in the prior art. The non-linear propulsion floor cleaning device changes its moving mode to be non-linear, thereby increasing the cleaning range of the floor cleaning device, reducing the cleaning dead zones, and improving the cleaning efficiency.

[0004] In order to achieve the above object, the present application provides a non-linear propulsion floor cleaning device, which includes two tools on a bottom. The two tools may be are two rotatable components rotating in opposite directions, and slightly inclined relative to a horizontal plane. Control signals are applied to control modules, so that the two rotatable components are rotated differently, and a driving force is generated to realize non-linear propulsion.

[0005] Preferably, the control modules are plate-brush motors or angle adjusting mechanisms.

[0006] Preferably, the angle adjusting mechanisms are push-rod motors.

[0007] Preferably, the rotatable components are plate brushes, rolling brushes, scouring pads, or magic eraser.

[0008] Preferably, the control signals are regular control signals.

[0009] Preferably, the regular control signals are sine wave signals or square wave signals.

[0010] The present application has following beneficial effects. The present application changes the moving mode of the floor cleaning device to be non-linear through improving the control mode, thereby increasing the cleaning range of the device, reducing cleaning dead zones, and improving cleaning efficiency. The non-linear movement is a kind of vibration-like frictional behavior against the floor, which can cause the whole brush plate to reciprocate leftward and rightward on the floor, so that the cleaning mode combines both reciprocating friction and rotating friction, which improves the cleaning effect and does not require additional reciprocating vibration elements.BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to facilitate the understanding of those skilled in the art, the present application will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present application.First Embodiment

[0014] As shown in FIG. 1 to 4, a non-linear propulsion floor cleaning device of the present application includes two plate brushes on the bottom. The two plate brushes can rotate in opposite directions, and be slightly inclined relative to a horizontal plane. Control signals are applied to plate-brush motors of the two plate brushes, so that the plate brushes have different rotational speeds, and a driving force is generated to realize non-linear propulsion.

[0015] A working process of the non-linear propulsion floor cleaning device is as follows. When A and B motors output according to square wave signals as shown in FIG. 2 or sine signals as shown FIG. 3, the two plate brushes may be driven with a first time period difference of θ. That is, during the first time period of θ, a rotational speed of the plate brush 1 is less than the rotational speed of the plate brush 2, causing the floor cleaning device to deflect and move around a plate brush 1 instead of moving in a straight line. Then, after the plate brush 1 and the plate brush 2 move for a period of time, a second time period of θ comes. During the second time period of θ, the rotational speed of the plate brush 2 is less than the rotational speed of the plate brush 1, which causes the floor cleaning device to deflect and move around the plate brush 2. As such, the floor cleaning device moves periodically in a reciprocating manner. The route is generally shown in FIG. 4. As long as a width W of the route is greater than the gap GAP, the coverage of the floor cleaning device can be maximized, avoiding the problem that the middle area cannot be covered.Second Embodiment

[0016] As shown in FIG. 5, a non-linear propulsion floor cleaning device of the present application includes two plate brushes on the bottom. The two plate brushes can rotate in opposite directions, and be slightly inclined relative to a horizontal plane. Control signals are applied to push-rod motors of the two plate brushes, so that a driving force is generated to realize non-linear propulsion through the rotational friction of each of the plate brushes at different inclination angles.

[0017] A working process of the on-linear propulsion floor cleaning device is as follows. In the case where the driving states of the two plate-brush motors are not adjusted (the rotational speeds thereof are constant), the inclination angles of the plate brushes adjusted by the push-rod motors can be increased. Since the moving directions of the plate brushes are directly related to the difference of the frictional force encountered by the plate brushes when rotating and contacting the floor, that is, on a cross section of a plane in which the plate brushes move, the plate brushes have inclination angles α and β relative to a horizontal direction as shown in FIG. 5. When performing linear movements in the moving direction of the floor cleaning device, the angles α and β are the same. It is only necessary to make an adjustment such that the angles α and β are different from each other, and the driving forces provided by the plate brushes on both sides are different from each other, so that the floor cleaning device can be deflected in a direction different from the moving direction, thereby achieving the non-linear movement.

[0018] The plate brushes may also be replaced with rolling brushes, scouring pads, or magic eraser by those skilled in the art can according to specific needs.

[0019] Certainly, other regular control signals can also be set, or the first embodiment and the second embodiment can also be combined, by those skilled in the art according to specific needs.

[0020] In the present application, the reciprocating route of the floor cleaning device changes little by adjusting the driving mode; and by adjusting the smoothness of the curve, the reciprocating acceleration of the floor cleaning device can be reduced, that is, the vibration feeling can be reduced. In this way, the change of the user's usage habits can be reduced, the realizability can be improved, and the cleaning effect and capacity can be improved.

[0021] As described above, the present application has the above-mentioned excellent characteristics, so that it can improve the performance that is not available in the prior art in use and become practical, and become a product with great practical value.

[0022] The above descriptions only illustrate preferred embodiments of the present application. For those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation and application scope, and the application of the specification of the present application should not be construed as limiting the present application.
