[0003] This invention relates to the field of smart homes, specifically to a control device for self-cleaning of floor scrubbers and a floor scrubber. Background Technology

[0004] Currently, existing floor scrubbers leave residue in the water system after cleaning, which can develop an unpleasant odor over time, leading to a poor user experience. To prevent this, floor scrubbers have incorporated a self-cleaning function to automatically rinse the pipes and brushes. In related technical solutions, the scrubber has a self-cleaning button on the handle. When the user presses this button to activate self-cleaning mode, the system rinses the pipes and brushes. However, manual operation becomes very inconvenient when the scrubber is placed against a wall. Furthermore, after filling the water tank, the user's hands are wet; pressing the self-cleaning button at this time may cause water to flow into the scrubber, affecting other functions and thus impacting usability. Therefore, there is currently no effective solution to make the self-cleaning operation of floor scrubbers more convenient and efficient. Summary of the Invention

Obviously, the drawings in the following description are only embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative labor on the basis of the provided drawings.

[0023] Figure 1 A self-cleaning control device for a scrubber provided by the embodiment of the present application is shown in the figure. DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear and obvious, the specific technical scheme of the present application will be further described in detail below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0025] The present application will be further described in detail below through specific embodiments combined with the drawings.

[0026] The embodiment of the present application provides a control device for self-cleaning of a scrubber, Figure 1 A self-cleaning control device for a scrubber provided by the present application is shown in the figure. Figure 1 As shown in the figure, the control device for self-cleaning of the scrubber comprises an excitation part and a sensing part 1021; the excitation part is arranged in the base part 101 of the scrubber, and is used to send a sensing signal when being operated; the sensing part 1021 is arranged in the main machine part 102 of the scrubber, receives the sensing signal, and triggers the main machine part 102 to perform a self-cleaning action when the sensing signal meets a preset condition.

[0027] Here, the scrubber is any type of scrubber that can be used in daily life, such as a hand-push scrubber, an electric scrubber, etc., and the type of the scrubber is not limited in the embodiment.

[0028] The excitation part can be arranged in the base part 101 of the scrubber, and the induction part 1021 can be arranged in the main machine part 102 of the scrubber. The base part 101 of the scrubber is used to support the main machine part 102 of the scrubber and to maintain the upright support of the main machine part 102. The main machine part 102 can include the main devices of the scrubber.

[0029] In some optional embodiments, the excitation part continuously emits the induction signal, and when the user's foot acts on the excitation part, the position of the excitation part and / or the signal strength changes, so that the induction part 1021 receives the induction signal with changed signal strength. When the strength of the induction signal reaches a preset threshold, it indicates that the induction part 1021 receives the induction signal that meets the preset condition, and further triggers the main machine part 102 to start performing the self-cleaning action based on the induction signal. In other optional embodiments, when the user's foot acts on the excitation part, the excitation part emits the induction signal, so that the induction part 1021 receives the induction signal. Accordingly, when the induction part 1021 receives the induction signal, it indicates that the induction signal that meets the preset condition is received, and further triggers the main machine part 102 to start performing the self-cleaning action based on the induction signal.

[0030] In some optional embodiments, the change in the position of the excitation part corresponds to the change in the signal strength received by the induction part 1021. For example, when the user's foot does not act on the excitation part, the excitation part is farthest from the induction part 1021, and accordingly, the induction part 1021 receives the signal with the minimum strength. When the user's foot acts on the excitation part, the distance between the excitation part and the induction part 1021 gradually decreases until it is minimum, and when the distance between the excitation part and the induction part 1021 is minimum, the induction part 1021 receives the signal with the maximum strength.

[0031] In some optional embodiments, the induction signal can be an induction signal caused by a specific physical property of a substance. For example, the excitation part can include a magnetic material, such as a magnet, which has a magnetic field, and different distances from the magnet correspond to different magnetic field strengths. In this case, the induction signal can be caused by the magnetic field of the magnet, and accordingly, the induction part receives the magnetic field strength (or magnetic induction strength) caused by the magnetic field of the magnet. In other optional embodiments, the induction signal can also be an electric signal emitted by an electronic device, an optical signal emitted by an optical device, etc.

[0032] In some optional embodiments, the excitation part includes an exciter 1011 and a stepping part 1012, the exciter 1011 is arranged on the first side of the stepping part 1012, and the second side of the stepping part 1012 extends to the outside of the base part 101.

[0033] Operating the treading component 1012 from the second side can control the first side of the treading component 1012 to move towards a first direction, so that the exciter 1011 is close to the induction part 1021.

[0034] Optionally, the induction part 1021 triggers the host part to perform a self-cleaning action when the intensity of the received induction signal reaches a preset threshold.

[0035] Here, the preset threshold can be set by the user in advance according to different use scenarios (such as different excitation devices), or the corresponding value can be configured in advance when the floor cleaning machine device is shipped, and if the use scenario changes, it can be reset.

[0036] In this embodiment, the treading component 1012 corresponds to a pedal or a pedal lever, one end (i.e. the second side) is outside the base part 101, and the other end (i.e. the first side) is inside the base part 101; based on the principle of leverage, when the user applies force to the treading component 1012 from the second side (i.e. steps on the pedal), the exciter 1011 at the first side of the treading component 1012 moves towards the first direction as the second side of the treading component 1012 moves towards the second direction, for example, as shown in Figure 1 The first direction points downward, and the second direction points upward; taking the exciter 1011 as a magnetic material, the magnetic field intensity detected by the induction part 1021 of the host part 102 will increase as the distance between the exciter 1011 and the induction part 1021 of the host part 102 decreases, and when the magnetic field intensity received by the induction part 1021 of the host part 102 is greater than a set value, the host part 102 will be triggered to start performing a self-cleaning action, thereby keeping the floor cleaning machine roller brush and pipeline clean and hygienic, preventing the roller brush from being dirty, breeding bacteria, and producing odor, etc. Therefore, the user does not have to worry about the inconvenience of operation, such as: when the floor cleaning machine is located in the corner of the wall, the user cannot start the self-cleaning mode due to the limitation of the placement position, when the user's hands are wet, it is not convenient to press the self-cleaning button, etc., thereby freeing the user's hands and improving the convenience of user operation.

[0037] In some optional embodiments, the first side of the treading component 1012 is provided with the exciter 1011, and the second side of the treading component 1012 is connected with the telescopic component 1014 fixed to the base part 101.

[0038] The treading component 1012 controls the first side of the treading component 1012 to move towards the second direction through the stretching of the telescopic component 1014, so that the exciter 1011 is away from the induction part 1021.

[0039] In the embodiment, the exciter 1011 can be an electric sensor, a magnetic sensor, an optical sensor or other sensors, which are not limited herein. The treading component 1012 can be a treadle or a pedal, and a support 1013 is needed to support the treading action. The support 1013 is fixed to the base 101, which is equivalent to the fulcrum of a lever. The support 1013 supports the treading component 1012 at a position close to the second side of the treading component 1012 or at a middle position of the treading component 1012, so that the displacement of the first side of the treading component 1012 moving towards the first direction is not greater than the position of the second side of the treading component 1012 moving towards the second direction, and thus the action of the user's foot is small in amplitude, which can make the exciter 1011 move a larger range. The exciter 1011 is located directly above the first side of the treading component 1012 (i.e., the first side of the treading component 1012), and a telescopic component 1012 is further arranged below the first side of the treading component 1012 (i.e., the second side of the treading component 1012). As an example, the telescopic component 1012 can be a spring or other telescopic device. When the user's foot removes the action on the second side of the treading component, the exciter 1011 can be controlled to move away from the sensing component 1021 by the stretching of the telescopic component 1012, so as to move to the initial position.

[0040] In an optional embodiment of the present application, the excitation part is configured to emit the sensing signal when an object is detected within a preset distance range.

[0041] In the embodiment, the excitation part can be arranged at the edge of the base 101, and the sensing component of the excitation part is outside the base 101 and the sensing direction is directed to the outside of the base 101. As an example, the excitation part can include a photoelectric sensor, and the sensing component of the photoelectric sensor is outside the base 101. When the user approaches the photoelectric sensor to a certain distance, the photoelectric sensor detects that there is an object within a preset distance range, and then emits the sensing signal. After the sensing component 1021 receives the sensing signal, the host component 102 is triggered to perform the self-cleaning action.

[0042] In the embodiment, the sensing component 1021 has the functions of receiving signals or detecting signals and performing functions. As an example, the functions of receiving signals or detecting signals can be realized by sensors or sensing chips, and the performing functions can be realized by controllers or control chips. Generally, the host component 102 includes a main control board for controlling the scrubber. The controller or control chip can be a controller or control chip arranged separately from the sensing component 1021 or can be realized by the main control board of the scrubber.

[0043] In this embodiment, after the exciter 1011 moves towards the first direction, the exciter 1011 and the inductor 1021 can be in contact or non-contact relationship.

[0044] By using the technical scheme of the embodiment of the present application, the inductor receives the inductive signal emitted by the exciter and meeting the preset condition through the action of the foot on the exciter, so that the scrubber performs the self-cleaning action, which is more convenient to operate and better in user experience.

[0045] Based on the above embodiment, the embodiment of the present application further provides a scrubber, which comprises a host unit and a base unit, the base unit being used for bearing the host unit; the scrubber further comprises any of the above devices for self-cleaning of the scrubber.

[0046] For example, the host unit comprises a clean water tank for storing clean water, a clean water pipeline, a water pump and a roller brush; the water pump is arranged on the clean water pipeline; one end of the clean water pipeline is connected to the clean water tank, and the other end of the clean water pipeline is connected to the roller brush;

[0047] When the host unit performs the self-cleaning action, the water pump is started to drain the clean water in the clean water tank to the roller brush through the clean water pipeline, so that the roller brush is cleaned under the action of the clean water.

[0048] In some optional embodiments, the host unit further comprises a water suction fan, a sewage pipeline and a sewage tank for storing sewage, one end of the sewage pipeline is connected to the roller brush, and the other end of the sewage pipeline is connected to the sewage tank;

[0049] When the host unit performs the self-cleaning action, the water suction fan is started to suck the sewage generated by cleaning the roller brush to the sewage tank through the sewage pipeline.

[0050] Here, during the self-cleaning process of the scrubber, the water pump of the scrubber sprays the clean water in the clean water tank on the roller brush through the clean water pipeline, and the roller brush rotates at a certain speed, the rotation speed and time of which are sufficient to use centrifugal force to throw most, especially most, of the sewage from the roller brush, and the water suction fan works synchronously to form negative pressure in the sewage pipeline, so as to suck most of the sewage for flushing the roller brush, especially the sewage thrown out by centrifugal force, to the sewage tank, thereby completing the cleaning of the roller brush.

[0051] It should be noted that the scrubber can further comprise a main control board, a key display board, a roller brush electrode and other devices.

[0052] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
