[0016] In order to more clearly describe the technical solutions of the embodiments of the present application or the prior art, the drawings necessary for describing the embodiments or the prior art are briefly described below. The drawings below are only embodiments of the present application, and it is also obvious to those skilled in the art that they can obtain other drawings based on the drawings provided without any creative efforts.

[0017] [Figure 1] FIG. 2 is a schematic diagram of a control device for self-cleaning of a floor cleaning machine provided by an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the specific technical solutions of the present disclosure are described in more detail below based on the drawings in the embodiments of the present disclosure. The following embodiments are used to explain the present disclosure, but are not used to limit the scope of the present disclosure.

[0019] Hereinafter, the present disclosure will be described in more detail with reference to the drawings by way of a description of the preferred embodiment of the present invention.

[0020] In an embodiment of the present disclosure, a control device for self-cleaning of a floor cleaner is provided. FIG. 1 is a schematic diagram of a control device for self-cleaning of a floor cleaner provided by an embodiment of the present disclosure. As shown in FIG. 1, the control device for self-cleaning of the floor cleaner includes an activation unit and a sensing unit 1021, the activation unit is installed in a base unit 101 of the floor cleaner and is for transmitting a sensing signal when operated, and the sensing unit 1021 is installed in a main body unit 102 of the floor cleaner, receives the sensing signal, and triggers the main body unit 102 to perform a self-cleaning operation when the sensing signal meets a predetermined condition.

[0021] Here, the floor washer refers to any type of floor washer that can be used in daily life, such as a hand-pushed floor washer, an electric floor washer, etc., and the type of floor washer is not limited in this embodiment.

[0022] The activation unit may be installed in the base unit 101 of the floor cleaning machine, and the detection unit 1021 may be installed in the main body unit 102 of the floor cleaning machine. The base unit 101 of the floor cleaning machine is for placing the main body unit 102 of the floor cleaning machine and for holding and supporting the main body unit 102 upright. The main body unit 102 may include the main elements of the floor cleaning machine.

[0023] In some selectable embodiments, the activation unit continuously transmits a sensing signal, and when the user's foot performs an action on the activation unit, the position and / or signal strength of the activation unit is changed, and the sensing unit 1021 receives the sensing signal with the changed signal strength. When the strength of the sensing signal reaches a predetermined threshold, it means that the sensing unit 1021 has received a sensing signal that satisfies a predetermined condition, and further triggers the main body unit 102 to start performing a self-cleaning operation based on the sensing signal. In some other selectable embodiments, when the user's foot performs an action on the activation unit, the activation unit transmits a sensing signal, and the sensing unit 1021 receives the sensing signal. Therefore, when the sensing unit 1021 receives the sensing signal, it means that the sensing signal that satisfies a predetermined condition is received, and further triggers the main body unit 102 to start performing a self-cleaning operation based on the sensing signal.

[0024] The change in the position of the activation unit corresponds to a change in the signal strength received by the sensing unit 1021, and exemplarily, when the user's foot does not move relative to the activation unit, the activation unit is farthest from the sensing unit 1021, and accordingly, the signal strength received by the sensing unit 1021 is the smallest. When the user's foot moves relative to the activation unit, the distance between the activation unit and the sensing unit 1021 gradually decreases until it becomes a minimum, and when the distance between the activation unit and the sensing unit 1021 becomes a minimum, the signal strength received by the sensing unit 1021 becomes a maximum.

[0025] In this embodiment, in some alternative embodiments, the sensing signal may be a sensing signal generated by a specific physical property of a material. Exemplarily, the activating unit includes a magnetic material such as a magnet, and the magnet has a magnetic field, and the magnetic field strength is different depending on the distance between the magnets, so that the sensing signal can be generated by the magnetic field of the magnet, and accordingly, what the sensing unit receives is the magnetic field strength (or magnetic induction strength) generated by the magnetic field of the magnet. In some alternative embodiments, the sensing signal may be an electric signal generated by an electronic element and / or an optical signal generated by an optical element, etc.

[0026] In some optional embodiments, the activation unit includes an activation device 1011 and a stepping member 1012, the activation device 1011 is installed on a first side of the stepping member 1012, and a second side of the stepping member 1012 extends to the outside of the base unit 101, and by operating the stepping member 1012 from the second side, the first side of the stepping member 1012 can be controlled to move in a first direction to bring the activation device 1011 closer to the sensing unit 1021.

[0027] Optionally, the sensing unit 1021 triggers the main body unit to perform a self-cleaning operation when the strength of the received sensing signal reaches a predetermined threshold.

[0028] Here, the predetermined threshold value may be preset by the user to a value suitable for the current usage scenario (e.g., different activation elements) according to different usage scenarios, or an appropriate value may be set in advance when the floor cleaning machine equipment is shipped and then reset when the usage scenario changes.

[0029] In this embodiment, the stepping member 1012 corresponds to a stepping plate or a stepping 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 outside of the base part 101, and based on the principle of leverage, when a user applies force to the stepping member 1012 from the second side (i.e., steps on the stepping plate with the foot), the actuator 1011 located on the first side of the stepping member 1012 moves in a first direction as the second side of the stepping member 1012 moves in a second direction. For example, referring to FIG. 1, the first direction is downward, and the second direction is upward. For example, when the activator 1011 is made of a magnetic material, as the distance between the activator 1011 and the sensing unit 1021 of the main body 102 decreases, the magnetic field strength detected by the sensing unit 1021 increases, and when the magnetic field strength received by the sensing unit 1021 located in the main body 102 exceeds a set value, the main body 102 is triggered to start executing a self-cleaning operation, thereby keeping the roll brush and piping of the washer clean and preventing the roll brush from becoming dirty, the proliferation of bacteria, the generation of unpleasant odors, etc. Therefore, for example, when the floor washer is located in a corner of a wall, the user does not need to worry about inconveniences in operation, such as being unable to turn on the self-cleaning mode due to restrictions on the installation location, or the inconvenience of pressing the self-cleaning button when the user's hands are wet, and the user's hands are freed, improving the convenience of operation.

[0030] In some alternative embodiments, an activator 1011 is installed on a first surface of the first side of the footing member 1012, and a telescopic member 1014 fixed to the base portion 101 is connected to a second surface of the first side of the footing member 1012. The footing member 1012 is controlled by tension of the telescopic member 1014 such that the first side of the footing member 1012 moves in a second direction, moving the activator 1011 away from the sensing portion 1021.

[0031] In this embodiment, the activator 1011 may be an electric sensor, a magnetic sensor, an optical sensor, or other sensor, and is not limited thereto. The stepping member 1012 may be a stepping lever or a stepping plate, and needs to be supported by a support part 1013 to realize a stepping action, and the support part 1013 is fixed in the base part 101 and corresponds to a fulcrum of a lever. The position where the support part 1013 supports the stepping member 1012 is close to the second side of the stepping member 1012 or is at the middle position of the stepping member 1012, so that the displacement of the first side of the stepping member 1012 moving in the first direction is equal to or smaller than the displacement of the second side of the stepping member 1012 in the second direction, and therefore, even if the width of the stepping action of the user's foot is small, the activator 1011 can be moved in a wider range. The activator 1011 is located directly above the first side of the stepping member 1012 (i.e., the first surface of the stepping member 1012), and an expandable member 1012 is further installed below the first side of the stepping member 1012 (i.e., the second surface of the stepping member 1012). As an example, the expandable member 1012 can be an expandable element such as a spring, and when the user's foot releases the movement of the stepping member against the second side, the tension of the expandable member 1012 moves the activator 1011 away from the sensing unit 1021, thereby moving the activator 1011 to its initial position.

[0032] In one alternative embodiment of the present disclosure, the initiator is for emitting the sensing signal when an object is detected within a predetermined distance range.

[0033] In this embodiment, the activating unit may be installed on the edge of the base unit 101, the sensing member of the activating unit is outside the base unit 101, and the detection direction faces the outside of the base unit 101. Exemplarily, the activating unit includes a photoelectric sensor, and the sensing member of the photoelectric sensor is located outside the base unit 101. When a user approaches within a certain distance from the photoelectric sensor, the photoelectric sensor detects that an object exists within the predetermined distance range and transmits the detection signal. After receiving the detection signal, the detection unit 1021 triggers the main body unit 102 to perform a self-cleaning operation.

[0034] In this embodiment, the sensing unit 1021 has a function of receiving or detecting a signal and a function of executing, and for example, the function of receiving or detecting a signal can be realized by a sensor or a sensing chip, and the function of executing can be realized by a controller or a control chip. Usually, a main control board for controlling the floor washer is included in the main body 102, and the controller or control chip may be a controller or control chip separately installed in the sensing unit 1021, or may be realized by the main control board of the floor washer.

[0035] In this embodiment, after the activator 1011 moves in the first direction, the activator 1011 and the sensing unit 1021 may be in a contact or non-contact relationship.

[0036] By adopting the technical solution of the embodiment of the present disclosure, the movement of the foot on the activation part causes the sensing part to receive the sensing signal sent by the activation part that meets the predetermined condition, and activates the floor cleaning machine to perform the self-cleaning operation, which is more convenient to operate and has a better user experience.

[0037] Based on the above-mentioned embodiments, an embodiment of the present disclosure further provides a floor cleaning machine, the floor cleaning machine having a main body and a base for placing the main body, and the floor cleaning machine further includes a control device for self-cleaning of any one of the floor cleaning machines of the above-mentioned devices.

[0038] Exemplarily, the main body includes a fresh water tank for storing fresh water, a fresh water pipe, a water pump, and a roll brush, and the water pump is installed in the fresh water pipe. The fresh water tank is connected to one end of the fresh water pipe, and the other end of the fresh water pipe is directed toward the roll brush. When the main body performs a self-cleaning operation, the water pump is started and the fresh water in the fresh water tank is guided to the roll brush through the fresh water pipe by the water pump, and the roll brush is cleaned by the action of the fresh water.

[0039] In some optional embodiments, the main body further includes a suction fan, a sewage pipe, and a sewage tank for storing sewage, wherein the suction direction of one end of the sewage pipe faces the roll brush and the other end of the sewage pipe is connected to the sewage tank, and when the main body performs a self-cleaning operation, the suction fan is activated and the sewage generated by cleaning the roll brush is collected in the sewage tank through the sewage pipe by the suction action of the suction fan.

[0040] Here, during the self-cleaning process of the floor washer, the water pump of the floor washer sprays the fresh water in the fresh water tank evenly onto the roll brush through the fresh water pipe, and at the same time the roll brush rotates at a certain speed, the speed and time of rotation are sufficient to use centrifugal force to shake off most of the wastewater, especially the vast majority of the wastewater, from the roll brush, and at the same time the water suction fan operates synchronously to create negative pressure in the wastewater pipe, so that most of the wastewater that has been washed off the roll brush, especially the wastewater that has already been shaken off by the centrifugal force, is sucked into the wastewater tank, and the cleaning of the roll brush is completed.

[0041] The floor washer may also include other elements such as a main control board, a button display panel, and a roll brush electrode.

[0042] The above are only specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited thereto, and all modifications or replacements that a person skilled in the art can easily think of within the technical scope described in the present disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be in accordance with the scope of protection of the claims.
