Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a method for a cleaning equipment to identify a plurality of floor brush assemblies. Background Art

[0002] With the wide use of cleaning equipment, the user's demand for cleaning equipment that can be applicable to different usage scenarios has gradually increased. Equipping a main body with different floor brush assemblies is a good method. However, since the functions and usage scenarios of each floor brush assembly are different, such as a bed brush, a water brush, a carpet brush, a floor brush, a vibrating brush, etc., the control logics of the main body for different floor brush assemblies are also different. Therefore, before normal operation, the main body needs to identify which floor brush assembly is installed at this time to enable different control logics. The prior art often uses identification devices such as Hall sensors, which have a high cost, and it is difficult to install identification devices such as Hall sensors on all floor brush assemblies in the case of limited structural space of the floor brush assemblies. Summary of the Invention

[0003] In order to overcome the above deficiencies, the present invention provides a method for a cleaning equipment to identify a plurality of floor brush assemblies. The cleaning equipment includes a main body and a plurality of different floor brush assemblies. Different control units B are respectively arranged on the plurality of different floor brush assemblies. The different control units B independently control the loads on their respective floor brush assemblies. Before the loads operate normally, the different control units B first turn on the loads to operate for a set duration with their respective different programs, and then selectively turn off a plurality of loads and keep them in the off state for a duration of T1, so as to enable the plurality of different floor brush assemblies to generate different current curves. A control unit A is arranged on the main body, and the control unit A distinguishes the plurality of different floor brush assemblies according to the different current curves.

[0004] Wherein, the main body further includes a power supply unit, a switch unit S1 and a switch unit S2. The floor brush assembly further includes a power conversion module. The control unit A detects the current value in the circuit through the a0 pin, controls the on / off of the switch unit S1 through the a1 pin, controls the on / off of the switch unit S2 through the a2 pin, and the switch unit S1 and the switch unit S2 are electrically connected to the power conversion module.

[0005] Wherein, the floor brush assembly further includes a switch unit S3. The control unit B controls the on / off of the switch unit S3 through the b1 pin, and the switch unit S3 is electrically connected to the load.

[0006] Wherein, the main body further includes a resistor R1. The resistor R1 is connected in series in the circuit connecting the main body and the floor brush assembly. The control unit A detects the voltage value across the resistor R1 through the a0 pin, so as to calculate the current value flowing through the floor brush assembly.

[0007]

[0008] ​Among them, the control unit A differentiates several different floor brush components according to the duration T1 of keeping the load closed and in the closed state.

[0009] The beneficial effects of the present invention are as follows: After the host identifies different floor brush components, different control methods can be adopted for different floor brush components to achieve the function of multi-purpose use of one machine. The method of current identification does not require the installation of identification devices such as Hall sensors, saving costs, and solving the problem that it is difficult to install identification devices such as Hall sensors on all floor brush components when the structural space of the floor brush components is limited.

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0013] As Figure 1 shown, a method for a cleaning device to identify several floor brush components, the cleaning device includes a host

[0014] and several different floor brush components. Different control units B are respectively arranged on several different floor brush components. Different control units B independently control the loads on their respective floor brush components. Before the load operates normally, different control units B first turn on the load to operate for a set duration according to their respective different programs, and then selectively turn off several loads and keep them in the closed state for a duration of T1, so as to make several different floor brush components generate different current curves. A control unit A is arranged on the host, and the control unit A differentiates several different floor brush components according to different current curves. After the host identifies different floor brush components, different control methods can be adopted for different floor brush components to achieve the function of multi-purpose use of one machine. The method of current identification does not require the installation of identification devices such as Hall sensors, saving costs, and solving the problem that it is difficult to install identification devices such as Hall sensors on all floor brush components when the structural space of the floor brush components is limited. Several different floor brush components can be a bed brush, a water brush, a carpet brush, a floor brush, a vibrating brush, etc. The loads on the floor brush components can be a roller brush motor, a water pump, a lighting lamp, etc., which are equipped according to the functions of different floor brush components.

[0015] Taking one of the floor brush components as an example, the control relationship between the main body and the floor brush component is described as follows: The main body further includes a power supply unit, a switch unit S1, and a switch unit S2, and the floor brush component further includes a power conversion module; the control unit A detects the current value in the circuit through the a0 pin, controls the on / off of the switch unit S1 through the a1 pin, controls the on / off of the switch unit S2 through the a2 pin, and the switch unit S1 and the switch unit S2 are electrically connected to the power conversion module. When the switch unit S1 and the switch unit S2 are turned on, the power supply unit of the main body can supply power to the floor brush component, and the power conversion module in the floor brush component can convert the voltage into a voltage that can supply power to the control unit B and the load to work.

[0016] In addition, the floor brush component further includes a switch unit S3, the control unit B controls the on / off of the switch unit S3 through the b1 pin, and the switch unit S3 is electrically connected to the load, so that the control unit B can control the on / off of the load. When the switch unit S3 is closed, the load works; when the switch unit S3 is opened, the load stops working.

[0017] The main body further includes a resistor R1, and the resistor R1 is connected in series in the circuit where the main body and the floor brush component are connected. The control

[0018] unit A detects the voltage value across the resistor R1 through the a0 pin, so as to calculate the current value flowing through the floor brush component. When the load works, the current increases; when the load stops working, the current decreases to around 0 mA. For the sake of easy understanding, the following takes the ideal state where the current decreases to 0 mA after the load stops working as an example for description. In actual situations, the current may be around 0 mA, but not the standard 0 mA, which is not considered here for the time being.

[0019] Such as Figure 2As shown, in one embodiment, three different floor brush components are used as examples. In the figure, the curves L1, L2, and L3 respectively correspond to the current curves of the three different floor brush components. It is not difficult to see that since the current of curve L3 does not reach 0 mA after tending to stable operation, it can be confirmed that the floor brush component corresponding to curve L3 does not turn off the load after turning on the load. At this time, it is relatively easy to distinguish the floor brush component corresponding to curve L3 from the floor brush components corresponding to curve L1 and curve L2. However, the floor brush components corresponding to curve L1 and curve L2 both experience the situation of first turning on the load and then turning off the load, so their current values both decrease to 0 mA, and it is impossible to distinguish the floor brush component corresponding to curve L1 from the floor brush component corresponding to curve L2. At this time, using the identification method of the present invention, monitor the duration T1 when the load is turned off and remains in the off state, that is, the floor brush component current value is 0 mA, and compare the duration T1 with the standard set value to confirm the type of the floor brush component. Specifically, the control unit B controls the duration for which the load of the floor brush component corresponding to curve L1 maintains a current of 0 mA to be t2 milliseconds, and the control unit B controls the duration for which the load of the floor brush component corresponding to curve L2 maintains a current of 0 mA to be t1 milliseconds, and then compare the duration for which the current of the floor brush component corresponding to curve L3 is 0 mA to be 0 milliseconds. At this time, the control unit A on the host periodically collects the real-time current value of the floor brush component and distinguishes several different floor brush components according to the different durations for which the current value of each floor brush component is 0 mA. More than three floor brush components can also be discriminated by this method, and the method is the same and will not be elaborated here. After the duration for which the load remains in the off state is sufficient to distinguish different floor brush components, then turn on the load to start the normal operation of the floor brush.

[0020] It should be noted that in order to make the image clear and concise in the figures of the embodiments of the present invention, the starting point of the current value of 0 mA is set as the same starting point. In actual situations, the starting points of the current values of the curves of all floor brush components are not the same, and the actual situation shall prevail.

[0021] Based on the inspiration of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
