Description

Technical Field

[0001] This utility model belongs to the technical field of swimming pool cleaning equipment, specifically relating to a power supply system for a swimming pool cleaning machine that has two charging and discharging modes. Background Technology

[0002] Existing electric pool cleaners are divided into two types based on their power supply method. One type is a pool cleaner powered by a cable: it is powered by an external power source, has strong cleaning capabilities, and can achieve high power and long-term operation. However, it requires dragging a cable during operation, and its range of use is limited by the length of the power cord. It also has problems such as limited working area, the risk of cable tangling, and inconvenience in carrying. The other type is a battery-powered pool cleaner: it is powered by a built-in rechargeable battery, does not require a cable during operation, and has high flexibility. However, it is limited by the battery capacity and has a limited battery life, requiring regular charging. It is suitable for small pools or temporary use scenarios.

[0003] Pool cleaners powered by cable connections have high power and long operating time, but lack flexibility; battery-powered pool cleaners without cables are highly flexible, but have low power and short operating time.

[0004] Currently, there is no pool cleaning machine that can achieve both high-power, long-term operation and flexible operation without the constraints of cables, thus combining the advantages of both usage scenarios.

[0005] Therefore, how to solve the above problems and provide a power supply system for a pool cleaning machine that is both efficient in cleaning and flexible in use is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a power supply system for a pool cleaner that combines two charging and discharging modes, addressing the problems in the existing technology.

[0007] Therefore, the above-mentioned objective of this utility model is achieved through the following technical solution:

[0009] The battery and charging module store electrical energy and power the pool cleaner.

[0010] An external power supply box provides an external power input;

[0011] When connected to an external power supply box, the control system switches the pool cleaner to the external power supply channel. The external voltage detection point and the external current detection point detect the voltage and current of the external power supply, and adjust the output of the external power supply to supply power to the load of the pool cleaner through the external control signal. At the same time, the charging module receives electrical energy from the external power supply through the internal charging input terminal to charge the battery. The control system sets the charging current of the charging module according to the working status, and detects the battery charging current in real time through the battery current detection point. The control system manages the external power input, the power supply of the pool cleaner and the battery charging in real time.

[0012] When the external power supply box is disconnected, the control system switches the pool cleaner to the battery-powered channel, supplying power to the pool cleaner through the battery input terminal.

[0013] While adopting the above technical solutions, this utility model may also adopt or combine the following technical solutions:

[0018] The control logic unit switches the power supply channel and adjusts the charging current of the charging module based on the voltage and current sampling results.

[0019] When a voltage input is detected in the external power channel and the voltage is within a reasonable range, the control system controls the use of the external power channel to power the host and shuts down the battery power rail.

[0020] When the battery voltage is detected to be lower than the preset threshold, the control system adjusts the charging current of the charging module according to the current consumption of the external power channel, without exceeding the total power of the external power supply, and opens the battery charging channel.

[0021] As a preferred technical solution of this utility model: the external power supply channel detects the power supply status of the external power supply box through a voltage sampling circuit and a current sampling circuit; the charging module detects the charging status of the battery through a voltage sampling circuit and a current sampling circuit.

[0022] As a preferred technical solution of this utility model: the control system includes a link control part, an analog control part, and a power control part;

[0023] The link control section includes a power button and a battery-assisted control. The power button starts or stops the pool cleaner body, and the battery-assisted control adjusts the battery power supply mode.

[0024] The analog control section includes multiple analog input pins for receiving sensor signals;

[0025] The power control section comprises multiple power control pins, including a charging output pin and a power reset pin. The charging output pin controls the charging state, and the power reset pin resets the power system.

[0026] The control system receives sensor signals by connecting the control pins of the control section and the analog input pins of the analog control section, optimizes energy distribution, and adjusts the power output through the power control section to achieve stable operation of the pool cleaning machine.

[0027] As a preferred technical solution of this utility model: the external power supply box is connected to the pool cleaning machine via a floating cable, providing high power and long-term working capability;

[0028] The connection interface between the floating cable and the pool cleaning machine is a high-strength interface, which can withstand the tension when the pool cleaning machine drags the cable.

[0029] As a preferred technical solution of this utility model: the charging module includes an integrated circuit setting pin and an integrated circuit status pin. The integrated circuit setting pin configures the charging mode, charging current parameters, and charging voltage parameters, and the integrated circuit status pin indicates the charging status and fault information.

[0030] Compared with existing technologies, the power supply system of this utility model for a pool cleaner with two charging and discharging modes has the following advantages: An external power supply box powers the pool cleaner body via a floating cable, while simultaneously charging the battery through an internal charging module, enabling simultaneous charging and operation. When the external power supply box is disconnected, the pool cleaner operates solely on its internal battery. The circuit design, through a hybrid power supply system combining external power and battery power, effectively solves the problems of poor flexibility with towed devices and low power and short operating time with non-towed devices. This combination of wired and wireless power supply capabilities allows for both high-power, long-duration operation and flexible wireless operation, improving cleaning efficiency and user experience. It not only achieves the dual goals of efficient energy management and flexible power supply but also enhances user experience and equipment reliability through automatic control.

[0038] The battery and charging module store electrical energy and power the pool cleaner.

[0039] An external power supply box provides an external power input;

[0040] When the external power supply box is connected, the control system switches the pool cleaner to the external power supply channel. External voltage and current detection points detect the voltage and current of the external power supply, and adjust the output of the external power supply to power the pool cleaner load through external control signals.

[0047] When a voltage input is detected in the external power channel and the voltage is within a reasonable range, the control system controls the use of the external power channel to power the host and shuts down the battery power rail.

[0048] When the battery voltage is detected to be lower than the preset threshold, the control system adjusts the charging current of the charging module according to the current consumption of the external power channel, without exceeding the total power of the external power supply, and opens the battery charging channel.

[0049] As a preferred technical solution of this utility model: the external power supply channel detects the power supply status of the external power supply box through a voltage sampling circuit and a current sampling circuit; the charging module detects the charging status of the battery through a voltage sampling circuit and a current sampling circuit.

[0058] Compared with the prior art, the power supply system of the pool cleaning machine of this utility model, which combines two charging and discharging modes, has the following advantages:

[0059] First, it combines the advantages of both power supply modes:

[0060] In external power supply mode, the main unit can operate at high power for extended periods while simultaneously charging the built-in battery.

[0061] In battery-powered mode, the main unit is free from cable constraints, allowing for flexible operation without the risk of tangling.

[0062] Second, improve efficiency and enhance user comfort:

[0063] Users can choose the power supply mode according to their needs, either charging while working or working wirelessly after charging.

[0064] The dedicated charging port supports fast charging, reducing charging waiting time.

[0065] Third, extend the service life of the equipment:

[0066] By optimizing the power supply mode through an intelligent control system, battery consumption can be reduced and the lifespan of the equipment can be extended.

[0067] Example 1

[0068] like Figure 1 As shown, this utility model's pool cleaning machine, which combines two charging modes, achieves efficient operation through both external power supply and battery power. Its workflow is as follows:

[0069] External power supply mode:

[0070] When the external power supply box is connected to the pool cleaner via a floating cable, external power enters the system through the EXT IN input terminal. The voltage and current of the external power supply are monitored in real time through the EXT VOLTAGE and EXT CURRENT detection points, and the output is regulated by the EXT CONTROL signal. The control system prioritizes using the external power supply to power the load, while simultaneously transferring a portion of the electrical energy to the charging module through the INTCHUG IN internal charging input terminal to charge the battery.

[0071] The charging module configures charging parameters such as charging current and charging voltage through the ICM SET pin, and monitors the charging status in real time, such as charging completion and overvoltage protection, through the ICM STAT pin, to ensure a safe and efficient charging process.

[0072] Battery powered mode:

[0073] When the external power supply is disconnected, the control system automatically switches to battery-powered mode. The battery provides power through the BATT IN input terminal, and the discharge current is monitored in real time by the BAT CURRENT detection point. The output is adjusted by the BAT CONTROL signal to ensure stable operation of the load. In this mode, the control system optimizes energy distribution, prioritizing the normal operation of the cleaning machine's core functions while extending battery life.

[0074] Charging management:

[0075] In external power supply mode, the charging module configures charging parameters via the ICM SET pin and monitors the charging status in real time via the ICMSTAT pin. When the battery level falls below a preset threshold, the control system automatically initiates the charging process to ensure the battery is always fully charged for use when the external power supply is disconnected.

[0076] Automatic control and energy optimization:

[0077] The control system uses pins such as POWER BUTTON and BATT AUX CONTROL in the Link Control section to control device startup, shutdown, and battery power mode adjustment. Simultaneously, the Analog Control section receives sensor signals (such as temperature and current) through pins like ANALOG MIX1 to optimize energy distribution in real time. The Power Control section adjusts the power output through pins such as CHGOUT and POWER RST to ensure stable system operation under different power supply modes.

[0078] Mode switching and energy management:

[0079] When the external power supply is reconnected, the control system automatically switches back to external power supply mode and continues charging the battery. This seamless switching between external power and battery power modes ensures the pool cleaner operates continuously and efficiently under various working conditions.

[0080] Through the above-described workflow, the pool cleaning machine of this invention, which combines two charging modes, achieves intelligent switching and efficient management of external power supply and battery power supply modes. This ensures continuous operation of the equipment and extends the battery's lifespan. At the same time, the charging module and control system ensure the safety and stability of the charging process.
