[0002] In daily life, water-using equipment can be seen everywhere, such as humidifiers, fish tanks or animal drinking water devices with water tanks. Water tanks are prone to breeding bacteria and producing odors, and usually require the sterilization function and the start and stop function of the water pump to be controlled according to a certain logic. Usually the water pump and the sterilization module are integrated together, so that only power supply can be achieved, and communication is impossible. The water pump and the sterilization module (such as ultraviolet lamps, electrolyzed water) can only be started and stopped synchronously, and independent control of the water pump and the sterilization module cannot be achieved.

[0003] In the related art, a pair of wireless communication modules (such as Bluetooth) are added at the power transmitting end and the receiving end respectively, so as to realize the separate control of the water pump and the sterilization module.

[0054] Figure 1 It is a structural schematic diagram of a pump body power supply control device provided according to an embodiment of the present application.

[0055] Reference Figure 1 As shown, some examples of embodiments of the present application provide a pump body power supply control device 10.

[0056] In some examples, the pump body power supply control device 10 may include a base 100 .

[0057] In some examples, the pump body power supply control device 10 may include a pump body 200. The pump body 200 may be disposed separately from the base 100. The pump body 200 may be configured to be disposed in the liquid storage container 20.

[0058] In some examples, liquid may be stored in the liquid storage container 20. The liquid may include water.

[0059] In some examples, a first induction coil 101 may be disposed in the base 100. The first induction coil 101 may be configured to transmit a control signal and electrical power according to the electrical signal parameter.

[0060] In some examples, the electrical signal parameter may include frequency.

[0061] In some examples, the electrical signal parameter may include a duty cycle.

[0062] In some examples, the electrical signal parameter may include voltage.

[0063] In some examples, the parameters of the electrical signal on the first induction coil 101 can be changed, thereby changing the field strength generated by the first induction coil 101 .

[0064] In some examples, the first induction coil 101 may include an inductor.

[0065] For some examples, refer to Figure 1 As shown, a second induction coil 201 may be disposed in the pump body 200 . The second induction coil 201 may be configured to be coupled with the first induction coil 101 .

[0068] In some examples, when the second induction coil 201 is coupled to the first induction coil 101 , the second induction coil 201 may receive the electrical power of the control signal sent by the first induction coil 101 .

[0069] In some examples, a change in the field strength generated by the first induction coil 101 may change the electric power on the second induction coil 201 .

[0070] In some examples of the embodiments of the present application, by setting a first induction coil 101 on the base 100, the first induction coil 101 transmits a control signal and electric power according to the electric signal parameters, the pump body 200 and the base 100 are separated, and the pump body 200 can be set in the liquid storage container 20, and the second induction coil 201 is set in the pump body 200; when the liquid storage container 20 is placed on the base 100, the second induction coil 201 can be coupled with the first induction coil 101, so as to receive the electric power and control signal of the first induction coil 101; in this way, the transmission of electric power and control signals between the base 100 and the pump body 200 is realized through the coupling of the second induction coil 201 and the first induction coil 101, and the transmission distance of the control signal is short. Only when the distance between the second induction coil 201 of the pump body 200 and the first induction coil 101 is less than the second preset distance, the second induction coil 201 can communicate with the first induction coil 101 and transmit electric power; therefore, no interference will be generated between other water-using equipment, and the occurrence of identification and matching errors is avoided.

[0071] For some examples, refer to Figure 1 As shown, a second controller 202 may be disposed in the pump body 200. The second controller 202 may be connected to the second induction coil 201.

[0072] In some examples, the second controller 202 can receive control signals and electrical power transmitted by the second induction coil 201 .

In some examples, the second controller 202 may also be other types of controllers.

[0077] In some examples, the second controller 202 may have a first communication interface 2021 .

[0078] In some examples, a sterilization mechanism 203 may be disposed in the pump body 200 . The sterilization mechanism 203 may be connected to the first communication interface 2021 .

[0079] In some examples, the control signal can be transmitted to the sterilization mechanism 203 through the first communication interface 2021 to control the start and stop of the sterilization mechanism 203 .

[0080] In some examples, the control signal can control the sterilization mechanism 203 to start through the first communication interface 2021. At this time, the second induction coil 201 can power the sterilization mechanism 203 through the first communication interface 2021, so that the sterilization mechanism 203 starts working. The sterilization mechanism 203 can sterilize the liquid in the liquid storage container 20.

[0081] In some examples, the first communication interface 2021 may include an RS232 interface.

[0082] In some examples, the first communication interface 2021 may include an RS485 interface.

[0083] In some examples, the first communication interface 2021 may include a Universal Serial Bus (USB) interface.

[0084] In some examples, the first communication interface 2021 may include a Type-C interface.

[0085] In some examples, the first communication interface 2021 may include a Metal Oxide Semiconductor Field Effect Transistor (MOSFET).

[0086] It can be understood that in some examples of the embodiments of the present application, the types of the first communication interface 2021 are only shown as some specific examples, and the specific type of the first communication interface 2021 is not limited.

[0087] In some examples, the second controller 202 can have a second communication interface 2022 .

[0088] In some examples, an impeller driver 204 may be disposed in the pump body. The impeller driver 204 may be connected to the second communication interface 2022.

[0089] In some examples, the control signal can control the impeller driver 204 to start via the second communication interface 2022 . At this time, the second induction coil 201 can supply power to the impeller driver 204 via the second communication interface 2022 , thereby making the impeller driver 204 work.

[0090] In some examples, the second communication interface 2022 may include an RS232 interface.

[0091] In some examples, the second communication interface 2022 may include an RS485 interface.

[0092] In some examples, the second communication interface 2022 may include a Universal Serial Bus (USB) interface.

[0093] In some examples, the second communication interface 2022 may include a Type-C interface.

[0094] In some examples, the second communication interface 2022 can include a MOSFET.

[0095] It can be understood that in some examples of the embodiments of the present application, the types of the second communication interface 2022 are only shown as some specific examples, and the specific type of the second communication interface 2022 is not limited.

[0096] In some examples, the impeller driver 204 may include an impeller motor. An output shaft of the impeller motor may be connected to the impeller.

[0097] In some examples, the impeller motor can drive the impeller to rotate, thereby pumping the liquid in the liquid storage container 20 .

[0098] According to the pump power supply control device 10 provided in the embodiment of the present application, the first communication interface 2021 of the second controller 202 is connected to the sterilization mechanism 203, and controls the start and stop of the sterilization mechanism 203 according to the control signal; the second communication interface 2022 of the second controller 202 is connected to the impeller driver 204, and controls the start and stop of the impeller driver 204 according to the control signal; in this way, the start and stop of the sterilization mechanism 203 and the start and stop of the impeller driver 204 can be independently controlled, which is conducive to the effective sterilization of the liquid in the water-using equipment. When in use, according to the control logic of the control signal, the sterilization mechanism 203 can be first started to sterilize the liquid for a preset time period, and then the impeller driver 204 can be started to pump the liquid.

[0099] In some examples, the base 100 may include a first shell (not numbered in the figure). The first induction coil 101 may be disposed in the first shell.

[0100] In some examples, the first shell can protect the first induction coil 101 and provide waterproofing and moisture-proofing.

[0101] In some examples, the first shell may be a plastic member.

[0102] In some examples, a circuit board may be disposed in the first housing, and the first induction coil 101 may be disposed on the circuit board.

[0103] In some examples, after the liquid storage container is placed on the base, in order to locate the position of the liquid storage container, a positioning gasket may be provided on a side of the first shell facing the liquid storage container.

[0104] In some examples, the positioning washers may be anti-slip washers.

[0105] In some examples, the pump body 200 may include a second housing. The second induction coil 201 may be disposed in the second housing.

[0106] In some examples, a circuit board may be disposed in the second housing, and the second induction coil 201 may be disposed on the circuit board.

[0107] In some examples, the second shell can protect and waterproof the circuit board.

[0108] In some examples, to facilitate installation of the circuit board into the second housing, one side of the second housing may have an opening, and the circuit board may be installed into the second housing through the opening.

[0109] In some examples, to waterproof the circuit board, the opening may be filled with epoxy resin, and the epoxy resin may seal the opening.

[0110] In some examples, the epoxy resin may have a melting point of 300° C.-400° C.

[0111] In some examples, the distance between the first induction coil 101 and the second induction coil 201 is relatively large due to the presence of the first shell, the positioning gasket, the liquid storage container, and the second shell between the first induction coil 101 and the second induction coil 201. The second induction coil 201 generates a large amount of heat when receiving the electric power sent by the first induction coil 101. That is, the heat generated by the second induction coil 201 is greater than or equal to the preset threshold.

[0112] In some examples, the first shell and the second shell may be thinned to reduce the heat generated by the second induction coil 201. Although the first shell and the second shell may be thinned, due to the presence of the first shell, the positioning gasket, the liquid storage container, the second shell and other components between the first induction coil 101 and the second induction coil 201, the distance between the first induction coil 101 and the second induction coil 201 is still large, and the heat generated is large.

[0113] In some examples, in order to ensure the strength of the first shell and the second shell, it is difficult to further thin the first shell and the second shell.

[0114] In some examples, although the epoxy resin has a melting point of 300°C-400°C, the heat generated by the second induction coil 201 will not affect the epoxy resin. However, the second induction coil 201 is arranged on the circuit board. In order to ensure that the heat generated by the second induction coil 201 is dissipated outward and does not affect other electronic components on the circuit board, the second induction coil 201 cannot be wrapped with epoxy resin.

[0115] In some examples, since the second housing is a plastic part, the heat generated by the second induction coil 201 may easily cause the second housing to melt and deform, thereby causing the epoxy resin to be unable to seal the opening, resulting in a poor sealing effect of the epoxy resin on the opening.

[0116] In some examples, the pump body 200 may include a temperature detection sensor. The temperature detection sensor may be disposed in the second housing.

[0117] In some examples, the temperature detection sensor may be disposed on a circuit board in the second housing. The temperature detection sensor may be configured to detect a temperature on the circuit board.

[0118] In some examples, when the temperature is greater than or equal to the preset temperature threshold, the second controller 202 may shut down the first communication interface 2021. That is, the second controller 202 may stop the sterilization mechanism 203 from working, thereby reducing the load on the second induction coil 201 and reducing the heat generated by the second induction coil 201.

[0119] In some examples, when the temperature is greater than or equal to a preset temperature threshold, the second controller 202 may shut down the second communication interface 2022. That is, the second controller 202 may stop the operation of the impeller driver 204, thereby reducing the load on the second induction coil 201 and reducing the heat generated by the second induction coil 201.

[0120] In some examples, when the temperature is greater than or equal to a preset temperature threshold, the second controller 202 can simultaneously shut down the first communication interface 2021 and the second communication interface 2022 to reduce the load on the second induction coil 201 and reduce the heat generated by the second induction coil 201 .

[0121] In some examples, the preset temperature threshold may be 85°C.

[0122] In some examples, the preset temperature threshold may be 90°C.

[0123] In some examples, the preset temperature threshold may be 95°C.

[0124] It is understood that in some examples of the embodiments of the present application, the preset temperature threshold can be set according to the tolerable temperature range of the second shell and the first shell. In some examples of the embodiments of the present application, the preset temperature threshold is only shown as some specific examples, and does not limit the preset temperature threshold.

[0125] In some examples of the embodiments of the present application, by setting a temperature detection sensor in the second shell, the temperature detection sensor can detect the temperature in the second shell. When the temperature is greater than or equal to the preset temperature threshold, the second controller 202 can stop the sterilization mechanism 203 through the first communication interface 2021, or stop the impeller driver 204 through the second communication interface 2022; in this way, the load on the second induction coil 201 can be reduced, thereby reducing the heat generated by the second induction coil 201, and the deformation of the second shell under high temperature can be avoided, thereby improving the sealing effect of the epoxy resin on the opening of the second shell. In some examples, refer to Figure 1 As shown, a first controller 102 may be disposed in the base 100. The first controller 102 may be connected to the first induction coil 101.

[0126] In some examples, the first controller 102 may include a microcontroller unit (MCU).

[0127] In some examples, the first controller 102 may include a central processing unit (CPU).

[0128] In some examples, the first controller 102 may include a Field Programmable Gate Array (FPGA).

[0129] It is understood that in some examples of the embodiments of the present application, the specific type of the first controller 102 is only shown as some specific examples, and does not limit the specific type of the first controller 102. In some examples, the first controller 102 may also be other types of controllers.

[0130] In some examples, the type of the first controller 102 may be the same as, close to, or similar to that of the second controller 202 .

[0131] In some examples, the type of first controller 102 can be different than the type of second controller 202 .

[0132] In some examples, the first controller 102 may be configured to output a control signal to the first induction coil 101 .

[0133] In some examples, the first controller 102 may be configured to output a control signal to the first induction coil 101 based on the high level signal.

[0134] In some examples, the first controller 102 may be configured to output a control signal to the first induction coil 101 based on the low level signal.

[0135] In some examples, the first controller 102 may modulate the high-level signal or the low-level signal using a frequency-shift keying (FSK) modulation method, and send the modulated signal to the second induction coil 201 via the first induction coil 101 .

[0136] In some examples, the second controller 202 may demodulate the control signal received by the second induction coil 201 using an FSK demodulation method.
