[0002] Floor cleaning equipment is a type of automated equipment that uses mechanical power, water jets, vacuum suction, and other technologies to clean various types of floors. It is widely used in homes, shopping malls, supermarkets, hotels, office buildings, and other places, greatly reducing the labor intensity of manual cleaning and significantly improving cleaning efficiency and quality. Floor scrubbers and carpet cleaners are subcategories of floor cleaning equipment, providing diverse cleaning solutions for different materials such as hard floors and carpets.

[0003] However, current household floor cleaning equipment on the market suffers from significant shortcomings in operation and control. Regardless of type, none are equipped with remote control functionality. Users must manually operate the control buttons on the machine to start and stop the equipment, and adjust parameters such as suction power, brush speed, and water spray intensity. This means that when cleaning large rooms, users must frequently move between the cleaning machine and the control point; when cleaning hard-to-reach areas such as under furniture or in narrow passageways, manual operation is extremely inconvenient, severely impacting cleaning efficiency and potentially causing user discomfort due to improper posture. This fails to meet the modern family's demand for efficient and convenient cleaning. Utility Model Content

The remote control includes a main control unit, a battery management circuit, a touch button detection circuit, a transmission circuit, and LED indicator lights.

[0027] The battery management circuit, touch button detection circuit, and wireless transmission circuit are all electrically connected to the main control unit; the control unit includes a receiving circuit, which is electrically connected to the control unit; the transmission circuit is signal-connected to the receiving circuit. The LED indicator is electrically connected to the main control unit.

The VCC pin is equipped with a capacitor for filtering, stabilizing the power supply voltage and preventing the remote control from crashing or interrupting its signal due to voltage fluctuations, ensuring continuous operation. The CHRG and STDBY pins are connected to LED1 to visually display the charging status (e.g., charging, fully charged), improving the user experience. The BAT pin is equipped with a capacitor for filtering, optimizing battery output characteristics, ensuring stable power supply, and preventing interruptions due to abnormal power levels during cleaning operations.

[0029] like Figure 3 As shown, the wireless transmission circuit includes a transmitter chip. The POUT pin of the transmitter chip is connected to the antenna through capacitor C6 and inductor L2. The XOSC pin is connected to a crystal oscillator chip, and the DIN pin is connected to the level signal transmitted from the main control chip. The transmitter chip is a 433 transmitter chip. The POUT pin optimizes the antenna impedance through the C6 / L2 matching network, improving signal transmission efficiency by 30% and increasing the effective distance by 20%, reaching an effective distance of up to 5 meters. The XOSC pin is connected to an external crystal oscillator to provide a high-precision clock of ±10ppm, reducing signal drift and lowering the bit error rate from 0.5% to below 0.1%. The DIN pin is directly connected to the main control level, reducing command delay to 5ms and achieving instant response. The 433 transmitter chip is characterized by strong penetration in the 433MHz band, enabling transmission through walls and improving anti-interference capability by 50% in complex home environments.

[0030] like Figure 5As shown, the touch button detection circuit includes a touch button management chip. This chip is connected to a touch spring via a resistor, and its output pins are electrically connected to the main control unit. Pins CIN0, CIN1, CIN2, and CIN3 of the touch button management chip are connected to resistors R10, R11, R12, and R13 respectively, and then to the first, second, third, and fourth touch springs.

[0032] The working principle of this utility model of floor cleaning equipment is as follows: The user triggers the operation by touching the touch button detection circuit via a touch spring. The touch button management chip collects the signal through a resistor network and transmits it to the main control chip of the main control unit. The main control chip parses the instruction and provides feedback on the operation and equipment status through LED indicators. At the same time, it transmits the processed instruction to the wireless transmission circuit. The transmitting chip of the wireless transmission circuit optimizes the signal through a capacitor and inductor matching network and ensures frequency stability with the help of a high-precision clock from an external crystal oscillator. It utilizes the strong penetration and anti-interference capabilities of the 433MHz band to transmit the signal to the host receiving circuit. After receiving the signal, the host receiving circuit drives the corresponding functional module to perform the cleaning operation. During this period, the battery management circuit monitors the battery status in real time through each pin of the chip, controls charging and discharging, and stabilizes the voltage, providing power assurance for the operation of the remote control.
