Description

Technical Field

[0001] The utility model relates to the technical field of floor washing machines, and particularly relates to a multifunctional floor washing device controlled by voltage. Background Art

[0002] Based on a vacuum cleaner, a water brush is modified. The vacuum cleaner has no self-cleaning function. After changing an accessory of the vacuum cleaner into a floor brush with a water tank, it can act as a floor washing machine, realizing the function of multi-purpose use. A floor washing machine with a self-cleaning function can improve the user experience.

[0003] For a traditional floor washing machine, a communication terminal is respectively arranged on the main machine and the base station. After the main machine is placed on the base station, the two communication terminals are in contact and conduct. At this time, the control board on the main machine can start the self-cleaning function, and there is no need to additionally arrange a control board for controlling self-cleaning on the base station.

[0004] Currently, for a vacuum cleaner main machine plus a new water brush accessory, since no communication terminal is arranged on the vacuum cleaner main machine, only a control board for controlling self-cleaning can be separately arranged on the water brush accessory, which will increase the cost. If following the idea of the previous floor washing machine, the old vacuum cleaner main machine that the user has already bought back cannot be adapted to the current water brush accessory.

[0005] In summary, a multifunctional floor washing device controlled by voltage is designed. Content of the Utility Model

[0010] Preferably, the positive electrode of the voltage regulation circuit is electrically connected to the signal acquisition end of the MCU_2 main board, and one of the I / O ends of the MCU_1 main board is electrically connected to the signal control end of the voltage regulation circuit. In the normal working state, the battery pack outputs a stable voltage to control the device to work. When mode switching is required, the I / O end of the MCU_1 main board sends a signal to the voltage regulation circuit, and the voltage regulation circuit adjusts the output voltage of the battery pack, so that the voltage output waveform has a short-term low voltage for a few seconds and then returns to the normal working voltage. After the signal acquisition end of the MCU_2 main board receives the short-term low voltage signal for a few seconds, the MCU_2 main board sends an instruction to other motors for mode switching.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present utility model will be described by way of examples and with reference to the accompanying drawings, wherein:

[0017] Figure 1 is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0019] As Figure 1 shown, a voltage-controlled multi-functional floor washing device includes a host device and a water brush device. The host device includes an MCU_1 main board, a voltage regulation circuit, and a battery pack. The battery pack is electrically connected to the water brush device through the voltage regulation circuit, and the MCU_1 main board is electrically connected to the voltage regulation circuit;

[0020] The water brush device includes an MCU_2 main board, a floor brush motor, and a rolling brush. The MCU_2 main board is electrically connected to the rolling brush through the floor brush motor, and the MCU_2 main board is electrically connected to the battery pack through the voltage regulation circuit.

[0021] The working principle of the device is as follows:

[0022] ① Assume that the voltage range of the PACK is: 0 to U, unit: V;

[0023] ② The MCU_1 main board outputs a regulation signal through the first switch, and outputs a voltage to Vout through the voltage regulation circuit;

[0024] ③ At this time, the voltage output range of Vout is restricted by the maximum and minimum voltages of the PACK;

[0025] ④ Therefore, the voltage range of Vout is also: 0 to U1, unit: V;

[0026] ⑤ The output end of Vout can be connected to the positive pole of the water brush device;

[0027] Note: The voltage regulation circuit can be a MOS switch circuit or a comprehensive integrated module; the control signal output by the MCU_1 main board through the first switch port can be a digital signal, such as PWM, or an analog signal, such as voltage, but not limited to these;

[0028] After the host is powered on, theoretically, the voltage of the PACK can be divided into N different voltages and output to the Vout terminal through the voltage regulation circuit;

[0029] Here, a detailed example is given in 3 segments:

[0030]

[0031] To maintain the normal operation of the water brush device, the Vout voltage output by the host device cannot be too small. Assuming the voltage output by Vout is Um, then Um <= U1. Each time the host is powered on, the Vout voltage will be adjusted to Um, and after a delay of M seconds, the Vout voltage will be adjusted to U1 and continuously output to supply power to the water brush device;

[0032] Next, it mainly describes that when the MCU_2 main board of the water brush device detects different positive terminal voltages, that is, different Vout voltages, it will enter different working modes or states:

[0033] Since the battery pack PACK generally has a low voltage protection and cannot output its full voltage completely, it is necessary to assume in advance that the minimum output voltage of PACK is Ulow, that is, the PACK output voltage mentioned above satisfies: Ulow <= U1;

[0034] According to the schematic diagram of the voltage change at the Vout terminal, it can be seen that:

[0035] 1. When Vout = Um = U1, delay for M seconds, that is, the signal control terminal of the MCU_1 main board sends a control signal to fully open the voltage regulation circuit. At this time, after the MCU_2 main board of the water brush device detects the voltage, it directly enters Mode A for operation;

[0036] 2. When Ux <= Um < Ulow and after a delay of M seconds, that is, the signal control terminal of the MCU_1 main board sends a control signal to open the voltage regulation circuit by x%, at this time, x% < 100%. At this time, after the MCU_2 main board of the water brush device detects the voltage, it directly enters Mode B for operation;

[0037] 3. When 0 < Um < Ux and after a delay of M seconds, that is, the signal control terminal of the MCU_1 main board sends a control signal to open the voltage regulation circuit by y%, at this time, y% < x%. At this time, after the MCU_2 main board of the water brush device detects the voltage, it directly enters Mode C for operation;

[0038] And so on. In theory, N states can be switched, but limited by the voltage detection accuracy of the MCU, there should be gaps between Ux, Uy,... Un and there should be no overlap or intersection.

[0039] Among them, the working modes of the device include: normal working mode, that is, the floor washing mode; self-cleaning mode, that is, the mode of cleaning the roller brush; water absorption mode, that is, the mode of absorbing water from the ground, etc.

[0040] In summary, the voltage regulation circuit can adjust the battery pack voltage to different preset values, and after the MCU_1 main board and the MCU_2 main board detect different preset values, different working modes can be started.

[0041] Specifically, the positive electrode of the voltage regulation circuit is electrically connected to the signal acquisition end of the MCU_2 main board, and one of the I / O ends of the MCU_1 main board is electrically connected to the signal control end of the voltage regulation circuit. In the normal working state, the battery pack outputs a stable voltage to control the operation of the device.

[0042] Specifically, the water brush device further includes a water pump motor and a clean water tank. The MCU_2 main board is electrically connected to the clean water tank through the water pump motor. The clean water tank is connected to the water pump motor, and then the water in the clean water tank is sprayed onto the rolling brush or the ground.

[0043] Specifically, the host device further includes a water suction motor. A first switch is provided between the MCU_1 main board and the water suction motor. The MCU_1 main board controls the on / off of the first switch. The water suction motor is used to suck the water on the ground into the sewage tank.

[0044] Specifically, the MCU_2 main board is electrically connected to the water pump motor through a second switch, and the MCU_2 main board is electrically connected to the floor brush motor through a third switch. The MCU_2 main board controls the on / off of the second switch and the third switch respectively. The MCU_2 main board controls the operation of the water pump motor and the floor brush motor by controlling the second switch and the third switch. The water pump motor is used to spray the water in the clean water tank onto the rolling brush or the ground to moisten the rolling brush or the ground for the purpose of mopping the floor. The floor brush motor is used to control the rotation of the rolling brush. The rolling brush rotates and then takes away the garbage on the ground to achieve the function of scrubbing the floor.

[0045] Specifically, both the MCU_1 main board and the MCU_2 main board are main board circuits mainly composed of MCUs.

The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
