Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular discloses a non-linear propulsion ground cleaning device. Background Technology

[0002] Current handheld floor cleaning devices use two horizontally placed brush discs that rotate in opposite directions to clean the floor. The angle of the brush discs controls the difference in the total friction force between the front and rear sides, providing the device with forward propulsion. Existing disc brush technology uses two disc brushes rotating in opposite directions. To avoid damage to the floor or between the two discs due to collisions, a certain gap is provided between the two disc brushes. This gap means that in actual use, the disc brushes cannot completely cover the entire floor. Therefore, the cleaning efficiency of the area between the two disc brushes is lower during operation, and there may be areas that are not cleaned thoroughly, thus affecting the user experience. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a non-linear propulsion ground cleaning device, which changes the movement mode of the device to non-linear, thereby increasing the cleaning range, reducing cleaning dead angles, and improving cleaning efficiency.

[0004] To achieve the above objectives, the present invention provides a nonlinear propulsion ground cleaning device, which includes two tools located at the bottom. The two tools are rotatable components that can rotate in opposite directions and are slightly tilted relative to the horizontal plane. A control signal is applied to a control module, and a driving force is generated by the different rotations of each rotating component to achieve nonlinear propulsion.

[0005] Preferably, the control module is a disc brush motor or an angle adjustment mechanism.

[0006] Preferably, the angle adjustment mechanism is a push rod motor.

[0007] Preferably, the rotating component is a disc brush, roller brush, scouring pad, or magic sponge.

[0008] Preferably, the control signal is a regular control signal.

[0009] Preferably, the regular control signal is a sine wave signal or a square wave signal.

[0010] The beneficial effects of the present invention are as follows: By improving the control method, the present invention changes the movement mode of the equipment to non-linear, thereby increasing the cleaning range of the equipment, reducing cleaning dead angles, and improving cleaning efficiency. Non-linear motion is a kind of vibration-like ground friction behavior, which can carry the entire brush plate to move back and forth on the ground. This combines the two types of cleaning methods: reciprocating friction and rotational friction, thereby improving the cleaning effect and eliminating the need to add reciprocating vibration elements.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] Example 1: Please refer to Figures 1-4 As shown, the present invention provides a nonlinear propulsion ground cleaning device, which includes two disc brushes located at the bottom. The two disc brushes can rotate in opposite directions and are slightly tilted relative to the horizontal plane. A control signal is applied to the disc brush motors of the two disc brushes, and a driving force is generated by the different rotation speeds of each disc brush to achieve nonlinear propulsion.

[0020] Its workflow is as follows: When motors A and B press... Figure 2 square wave signal or Figure 3 When the sinusoidal signal is output, the two brush drives will differ by a time interval θ. During this time interval, the rotational speed of brush 1 is less than that of brush 2, causing the device to deflect around brush 1 instead of moving in a straight line. After brushes 1 and 2 have traveled for a period of time, another time interval θ will pass, during which brush 2 will rotate less than brush 1, causing the device to deflect around brush 2. This cycle repeats. The route is roughly as follows: Figure 4As shown, as long as the path width W is greater than the gap GAP, the device coverage area can be maximized, avoiding the problem of insufficient coverage in the middle area.

[0021] Example 2: Please refer to Figure 5. A non-linear propulsion ground cleaning device of the present invention includes two disc brushes located at the bottom. The two disc brushes can rotate in opposite directions and are slightly tilted relative to the horizontal plane. A control signal is applied to the push rod motor of the two disc brushes. The non-linear propulsion is achieved by generating driving force through the rotation friction of each disc brush at a different tilt angle.

[0022] Its working process is as follows: Without adjusting the two disc brush motor drives (rotation speed constant), a push rod motor can be added to adjust the tilt angle of the disc brush. Since the advance direction of the disc brush is directly related to the frictional force of its rotational contact with the ground, that is, the disc brush will have a cross-section on the advance plane as... Figure 5 The tilt angles α and β in the horizontal direction are shown. When the equipment moves in a straight line in the direction of travel, angles α and β are the same. However, by simply adjusting the angles α and β to be different, the driving force provided by the brushes on both sides will be different, which will make the equipment perform a yaw motion in a direction different from the direction of travel, thus achieving nonlinear motion.

[0023] Depending on specific needs, those skilled in the art can also modify the disc brush into a roller brush, scouring pad, or magic sponge.

[0024] Of course, depending on specific needs, those skilled in the art can also set other regular control signals, or combine Embodiment 1 with Embodiment 2.

[0025] This invention can reduce the variation in the reciprocating path of the device by adjusting the driving mode, and can reduce the reciprocating acceleration of the device by adjusting the smoothness of the curve, that is, reduce the vibration, thereby reducing the need to change the user's usage habits, improving feasibility, and improving cleaning effect and capability.

[0026] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0027] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of the present invention specification should not be construed as a limitation of the present invention.
