Referring to fig. 1, an underwater cleaner provided by an embodiment of the present application may include: a charging port, a contact module, and a battery. The underwater cleaning machine is characterized in that the contact module is arranged between the charging port and the battery, the contact module is kept in an off state during non-charging, and the contact module is conducted under the condition that the charging port detects a power supply signal of a power supply so that the power supply charges the battery. Possibly, the contact module is a mechanical contact switch, which may comprise a relay, the contact module having at least two normally open contacts. For example, the contact module may include two relays, each relay including a normally open contact; it is also possible that one relay comprises two normally open contacts. The charging device comprises a charging port, a normally open contact, a charging port and a negative terminal, wherein the positive terminal of the charging port corresponds to the normally open contact, and the negative terminal of the charging port corresponds to the other normally open contact. Therefore, the embodiment of the application can completely isolate the positive and negative ends of the charging port from the contact modules, so as to avoid the problems of electric leakage and the like caused by the electrolytic loop formed by the charging port and other components.
Further, the underwater cleaning machine in the embodiment of the application can further comprise a charging management module. The charge management module is configured to monitor battery charging current and/or voltage. Specifically, the charge management module is connected with the contact module. The charge management module may include a charge management chip and corresponding peripheral circuitry.
Possibly, the charging management module of the embodiment of the application can be arranged between the contact module and the charging port, and also can be arranged between the contact module and the battery. It can be understood that the charging management chip can adjust and output the power supply to the battery voltage for battery charging, so that the power supply can be the voltage of the relay, so that the mechanical contact switch can be closed after the power supply is inserted into the charging port, and the circuit loop is conducted. In addition, if the battery is charged by adopting the USB power supply with the same voltage as the relay, when the voltage and the current of the USB power supply are collected by the charging management chip, the mechanical contact switch can be directly controlled to be closed so as to enable the USB power supply to start charging the battery.
Possibly, the underwater cleaning machine in the embodiment of the application can further comprise a voltage stabilizing module. The voltage stabilizing module and the contact module can be arranged between the charging port and the battery, and the contact module is controlled to be conducted through the voltage stabilizing module under the condition that the charging port detects a power supply signal of the power supply so as to enable the power supply to charge the battery. Referring to fig. 2, when the voltage stabilizing module obtains a power supply signal of the power supply, a relay in the contact module can be controlled to be closed, so that the charging loop is conducted, and the power supply starts to charge the battery.
Possibly, the underwater cleaner in the embodiment of the application may further include: and the controllable switch module and the control module. The controllable switch module is arranged between the contact module and the battery, the input end of the control module is connected with the contact module, and the output end of the control module is connected with the controllable switch module. Under the condition that the control module detects a power supply signal output by the contact module, the control module controls the controllable switch module to be conducted so as to charge the battery by the power supply; or under the condition that the control module detects the power supply signal which is not output by the contact module, the control module controls the controllable switch module to be disconnected so as to stop the power supply from charging the battery.
In particular, at least one controllable switch module in embodiments of the present application may be disposed in a positive loop and/or a negative loop between the charging port and the battery. After the underwater cleaning machine is fully charged or the charger and/or the charging power supply are/is separated, the controllable switch module is in an off state; after the subsea cleaner charger and/or the charging power source is/are disconnected, the contact module is in an open state.
Referring to fig. 3, after the mechanical contact in the electric shock module is closed, the control system may acquire a voltage sampling signal, so that the control system may send a turn-on instruction to the controllable switch in the controllable switch module to turn on a line between the mechanical contact and the battery, conversely, when the power supply is removed from the charging port, the power supply signal immediately disappears, that is, the control system detects a change of the power supply signal, and the control module needs to control the controllable switch module to be turned off so as to prevent phenomena such as equipment leakage caused by discharging the battery to the direction of the mechanical contact, electrolytic corrosion at the charging port and the like.
Further, the underwater cleaner in the embodiment of the application may further include: and a voltage sampling module. The voltage sampling module is connected with the input end of the control module. According to the embodiment of the application, the voltage at two ends of the battery can be collected through the voltage sampling module; and under the condition that the voltage at two ends of the battery is larger than the sampling voltage threshold value, the controllable switch module is controlled to be disconnected through the control module.
It can be understood that the embodiment of the application can determine whether the battery is full or not by collecting the voltages at the two ends of the battery, and particularly can judge the battery by setting the sampling voltage threshold value, when the voltages at the two ends of the battery are larger than the sampling voltage threshold value, the battery is full, and the control system can control the controllable switch to be disconnected so as to avoid the damage to the battery possibly caused by long-time charging.
See the internal module schematic of the subsea cleaner shown in fig. 3. The underwater cleaning machine in the embodiment of the application can further comprise: the sampling module I and the adoption module II can comprise a voltage sampling module and/or a current sampling module. The sampling module I is used for collecting data in the battery charging and discharging loop and transmitting the data to the control module, and the control module can judge whether the controllable switch module is turned on or turned off according to the data of the sampling module I. The current sampling module is arranged between the negative electrode of the battery and the control module, and samples the charge and discharge current of the battery through the current sampling module; under the condition that the charging current of the battery exceeds the sampling current threshold range, the controllable switch module is controlled to be disconnected by the control module; the sampling module II is arranged between the battery and the control module to collect parameters of the battery and transmit the parameters to the control unit; the control unit comprehensively judges and controls the on and off of the controllable switch module according to the sampling data. In addition, the underwater cleaning machine may further include a power button, the power button connecting the battery and the control unit such that the battery supplies power to the control unit.
Possibly, the underwater cleaner in the embodiment of the application may further include: and a temperature sampling module. The temperature sampling module is arranged between the battery and the control module. Acquiring the temperature of the battery through a temperature sampling module; and under the condition that the temperature of the battery exceeds the temperature threshold range, the control module controls the controllable switch module to be disconnected.
In particular, the temperature sampling module in embodiments of the present application may employ a temperature sensor that is at least one thermistor (Negative Temperature Coefficient, NTC) resistor. The temperature sensor is used for monitoring the temperature of the battery core in the charging and discharging process of the battery by the control system, the temperature data can be displayed through a display interface (panel or application program APP) of the control system, so that a user can know the temperature state of the battery core, if the temperature is abnormal, the control system can automatically close the controllable switch, and the user can also close the controllable switch in a manual mode, so that a charging and discharging loop of the battery is cut off, and the use safety of the battery is ensured.
The underwater cleaning machine in the embodiment of the application can further comprise: and a signal amplifying module. The signal amplifying module is arranged between the current sampling module and the control module. Amplifying the charge and discharge current of the battery through a signal amplifying module to obtain the amplified current of the battery; determining a voltage corresponding to the amplified current of the battery; if the voltage corresponding to the amplified current of the battery is smaller than the preset reference voltage, the battery is in a charging state; if the voltage corresponding to the amplified current of the battery is greater than or equal to the preset reference voltage, the battery is in a discharging state.
It can be understood that, since the current direction in the charging loop is opposite to the current direction in the discharging loop, the digital circuit adopted by the control system can only process signals in a single direction, so that the signals output by the battery need to be amplified to convert the current in the positive and negative directions into the current signals in the single positive direction, so that the control system can perform analog-to-digital AD sampling.
See the schematic circuit diagram of the signal amplifying module shown in fig. 4. The signal amplification module IS arranged in a negative electrode loop of a battery, a specific IS port IS connected with the negative electrode of the battery, a signal IS connected with a negative electrode input end 4 of a signal amplifier through a resistor R20, a resistor R22 and a capacitor C20 (the resistor R22 and the capacitor C20 are also mutually connected in parallel) are connected in parallel between the negative electrode input end 4 of the signal amplifier and an output end 1 of the signal amplifier, one end of a positive electrode input end 3 of the signal amplifier IS grounded through a resistor R21, and the other end of the positive electrode input end 3 IS connected with a reference source VREF through a resistor R23 and a capacitor C21 which are mutually connected in parallel respectively. The reference source may be set to 2.5V voltage, so that the signal output by the battery is increased to 0-5V, for example, after the voltage corresponding to the charge-discharge current of the battery is amplified, the voltage is greater than 0V but less than 2.5V of the reference voltage, which indicates that the battery is in a charged state; if the voltage is greater than or equal to the preset reference voltage of 2.5V, the battery is in a discharging state.
Specifically, the controllable switch module in the embodiment of the application can be any one of an N-channel insulated gate field effect transistor NMOS, a P-channel insulated gate field effect transistor PMOS and a relay. Because NMOS, PMOS and relay are all low internal resistance devices, under the condition of the same voltage for sampling, the generated current is larger than the current generated by the diode in the related art, so the charging method provided by the embodiment of the application has higher efficiency and effectively saves the charging time. In addition, because the voltage drop of 0.6-0.7V exists between the anode and the cathode of the diode, under the condition of using larger power supply voltage, the high current can improve the temperature of the diode, the safety of a charging structure is influenced, and a certain voltage drop possibly exists between the power supply and the battery due to the influence of the voltage drop, so that the battery cannot be fully charged.
Referring to fig. 5, a schematic circuit diagram of an underwater robot using an NMOS controllable switch module is shown. Specifically, the positive pole end of the mouth that charges links to each other with relay K1's one end, and the negative pole extreme of the mouth that charges links to each other with relay K2's one end, has parallelly connected diode D2 between relay K1 and the relay K2 to the positive pole end of the mouth that charges still links to each other with voltage stabilizing module, and specifically this voltage stabilizing module includes: the diode D1, the resistor R1, the zener diode ZD1, the triode Q1 and the capacitor C1 are connected with the positive electrode terminal of the charging port. The positive terminal of the diode D1 is connected with the positive terminal of the charging port, the negative terminal of the diode D1 is connected with one end of the resistor R1 and the collector of the triode Q1 respectively, the other end of the resistor R1 is connected with the negative terminal of the zener diode ZD1 and the base of the triode Q1 respectively, the positive terminal of the zener diode ZD1 is grounded, the emitter of the triode Q1 is connected with one end of the relay K1 and one end of the relay K2 respectively and one end of the capacitor C1 respectively, and the other end of the capacitor C1 is grounded. The other end of the relay K1 is connected with the positive electrode of the battery B1 through an NMOS controllable switch module, the other end of the relay K2 supplies power to the control system through a resistor R2, a resistor R3 and a diode D3, and the two ends of the resistor R3 are connected with a capacitor C2 in parallel to input sampling signals at the two ends of the resistor R3 to the control system.
