At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0049] The liquid cooling device provided in the embodiment of the present application is used to cool down the liquid to be cooled. The liquid to be cooled can be a liquid heated by a liquid heater. Based on the different types of liquid heaters, the heated liquid will also be different. Exemplarily, the liquid heater is but not limited to a kettle, an oil heater, a milk heater, etc. The liquid cooling device can be arranged on the liquid heater, and the liquid heated by the liquid heater is directly cooled down, and then flows out from the liquid outlet channel for use by the user. In this case, the liquid outlet channel is a liquid outlet channel shared by the liquid heater and the liquid cooling device. Alternatively, the liquid cooling device can also be arranged separately from the liquid heater, in which case the liquid outlet channel is the liquid outlet channel of the liquid cooling device.

[0050] In one embodiment, as shown in FIG. 1 , a liquid cooling device is provided, including a first storage area 102, a cooling switch 104, and a second storage area 106. The first storage area 102 is used to store a heat dissipation medium having a specific heat capacity smaller than the specific heat capacity of the liquid to be cooled. The cooling switch 104 is disposed between the first storage area 102 and the second storage area 106, and is used to connect the first storage area 102 and the second storage area 106 when it is turned on, so that the heat dissipation medium stored in the first storage area 102 flows into the second storage area 106. The second storage area 106 is disposed in a liquid outlet channel, and is used to cool the liquid flowing through it by means of the stored heat dissipation medium. Since the specific heat capacity of the heat dissipation medium is smaller than the specific heat capacity of the liquid heated by the liquid heater, when the liquid needs to be cooled, the cooling switch 104 can be turned on to allow the heat dissipation medium stored in the first storage area 102 to flow into the second storage area 106, so that the heat dissipation medium stored in the second storage area 106 cools the liquid in the liquid outlet channel and then flows out. The cooling speed is fast, which reduces the time the user has to wait for the liquid to cool down naturally, thereby improving the convenience of use.

[0051] Among them, the type of heat dissipation medium is not limited and can be determined according to the type of liquid to be cooled. For example, if the liquid to be cooled is water, the heat dissipation medium can be sand, and further, it can be fine sand with smaller particles. The specific heat capacity of sand is smaller than that of water, and it absorbs heat and heats up quickly, and dissipates heat and cools down quickly. The temperature difference between day and night in the desert is large, with a temperature of tens of degrees during the day, and when the sun sets, it can drop to a temperature of tens of degrees below zero in a short time. Therefore, by using sand as a heat dissipation medium, the heat dissipation efficiency is high and the cooling speed is fast.

[0052] The first storage area 102 is used to store the heat dissipation medium. When the liquid does not need to be cooled, all or most of the heat dissipation medium can be stored in the first storage area 102 for use when needed. The size and shape of the first storage area 102 can be set according to actual needs. For example, the first storage area 102 is a rectangular cavity. Generally, the volume of the first storage area 102 is greater than the volume of the second storage area 106, so that when the heat dissipation medium stored in the first storage area 102 flows into the second storage area 106, the second storage area 106 can be filled, which is conducive to improving the cooling efficiency.

[0053] The cooling switch 104 is disposed between the first storage area 102 and the second storage area 106. When the cooling switch 104 is turned on, the first storage area 102 and the second storage area 106 can be connected, so that the heat dissipation medium stored in the first storage area 102 flows into the second storage area 106. When the cooling switch 104 is turned off, the first storage area 102 and the second storage area 106 are not connected, and the heat dissipation medium cannot be transmitted. Therefore, the start and end of the liquid cooling process can be controlled by the cooling switch 104. Furthermore, the cooling switch 104 is a valve with an adjustable opening. By adjusting the valve opening, the amount and speed of the heat dissipation medium transmitted between the first storage area 102 and the second storage area 106 can be adjusted, thereby adjusting the cooling speed.

[0054] The second storage area 106 is arranged in the liquid outlet channel, and is used to cool the liquid flowing through by the stored heat dissipation medium. It can be understood that one end of the liquid outlet channel is the liquid inlet, and the other end is the liquid outlet. The dotted arrow in the figure is the direction of liquid flow. When the liquid needs to be cooled, the liquid to be cooled can be injected from the liquid inlet, and the injected liquid reaches the liquid outlet through the liquid outlet channel, and the user can take the liquid at the liquid outlet. Among them, the second storage area 106 is arranged in the liquid outlet channel, and the liquid flowing through the liquid outlet channel will flow through the second storage area 106. In the case where a heat dissipation medium is stored in the second storage area 106, the liquid will flow through the heat dissipation medium stored in the second storage area 106, and the heat dissipation medium can cool the liquid flowing through, thereby reducing the temperature of the liquid reaching the outlet, so that the user can take the liquid with a lowered temperature faster, reducing the waiting time of the user, and better meeting the needs of the user.

[0055] In this embodiment, since the specific heat capacity of the heat dissipation medium is smaller than the specific heat capacity of the liquid heated by the liquid heater, when the liquid needs to be cooled, the cooling switch 104 can be turned on to allow the heat dissipation medium stored in the first storage area 102 to flow into the second storage area 106, so that the heat dissipation medium stored in the second storage area 106 cools the liquid in the liquid outlet channel and then flows out. The cooling speed is fast, which reduces the time the user has to wait for the liquid to cool down naturally, thereby improving the convenience of use.

[0056] Furthermore, the number of the second storage areas 106 is not unique, for example, there may be one, which can play a role in cooling the liquid. Alternatively, in other embodiments, as shown in FIG. 2 , the number of the second storage areas 106 is more than two, the number of the cooling switches 104 is the same as the number of the second storage areas 106 , and each second storage area 106 is connected to the first storage area 102 via a cooling switch 104 .

[0057] Among them, the number of cooling switches 104 is the same as the number of second storage areas 106, both of which are more than two. Each second storage area 106 is connected to the first storage area 102 through a cooling switch 104, that is, the connection status of each second storage area 106 and the first storage area 102 is controlled by a cooling switch 104, and whether the heat dissipation medium is stored in each second storage area 106 and the amount of the heat dissipation medium stored are independent of each other.

[0058] The number of cooling switches 104 and the number of second storage areas 106 are not limited, and can be two, three or more, depending on the cooling demand. When the number of cooling switches 104 and the number of second storage areas 106 are both more than two, different numbers of cooling switches 104 can be controlled to store heat dissipation media in different numbers of second storage areas 106, thereby adjusting the heat dissipation effect. For example, different numbers of cooling switches 104 can be controlled to open according to the amount of liquid to be cooled. Specifically, when the amount of liquid to be cooled is small, one cooling switch 104 can be controlled to open, so that one second storage area 106 stores the heat dissipation medium from the first storage area 102 to meet the cooling demand. When the amount of liquid to be cooled is large, multiple cooling switches 104 can be controlled to open, so that multiple second storage areas 106 store the heat dissipation medium from the first storage area 102, and the amount of heat dissipation media participating in cooling the liquid is large, so as to improve the cooling effect.

[0059] In this embodiment, the number of the second storage areas 106 is more than two, the number of the cooling switches 104 is the same as the number of the second storage areas 106, and each second storage area 106 is connected to the first storage area 102 via a cooling switch 104. Therefore, different numbers of cooling switches 104 can be controlled according to actual needs, and the amount of heat dissipation medium involved in cooling can be adjusted, thereby adjusting the cooling intensity, so that the liquid cooling device can meet different cooling needs, and expand the application range of the liquid cooling device.

[0060] In addition, the structure of the second storage area 106 is not unique. For example, in one embodiment, the second storage area 106 includes two layers of filter screens that are relatively spaced apart, and the space between the two layers of filter screens is used to store the heat dissipation medium. The filter screen is used to block the heat dissipation medium and pass the liquid. The area formed between the two layers of filter screens in the second storage area 106 is the storage space of the second storage area 106, which is used to accommodate the heat dissipation medium. Among them, the first layer of the two layers of filter screens is arranged near the liquid inlet of the liquid inlet channel, and the second layer is arranged near the liquid outlet of the liquid inlet channel. The specific structure of the filter screen can be determined according to actual needs and is not limited here.

[0061] The filter screen can pass liquid, so that when the liquid enters the liquid outlet channel from the liquid inlet and flows through the liquid channel, it can pass through the first layer of filter screen to reach the second storage area 106, so that the heat dissipation medium in the second storage area 106 cools the incoming liquid. The cooled liquid flows out through the second layer of filter screen and reaches the liquid outlet for use by the user.

[0062] The filter is used to block the heat dissipation medium, so that the heat dissipation medium stored in the second storage area 106 is confined in the second storage area 106 and cannot diffuse into the liquid, thereby preventing the heat dissipation medium from mixing into the liquid and preventing the user from taking the liquid containing the heat dissipation medium, which is beneficial to ensuring the working performance of the liquid cooling device.

[0063] In this embodiment, the second storage area 106 includes two layers of filter screens arranged at a relative interval, and the space between the two layers of filter screens is used to store the heat dissipation medium. Based on the structure of the two layers of filter screens, the liquid can flow through the second storage area 106, and the heat dissipation medium stored in the second storage area 106 can be used to cool the flowing liquid, and the heat dissipation medium can be prevented from diffusing into the liquid, which is conducive to improving the reliability of the liquid cooling device.

[0064] Furthermore, in one embodiment, a conveying device is provided in the second storage area 106 for conveying the heat dissipation medium stored in the second storage area 106 to the first storage area 102 .

[0065] The type of the conveying device is not limited, and may be, for example, a conveying crawler. When the heat dissipation medium is stored in the second storage area 106, the heat dissipation medium may be stored on the conveying crawler.

[0066] After the liquid cooling process is completed, the heat dissipation medium stored in the second storage area 106 can be transferred to the first storage area 102 by controlling the movement of the conveyor belt, so as to realize the automatic reflux of the heat dissipation medium and reduce the user's usage load. For example, the conveyor belt can be a small miniature conveyor belt, which is convenient for being arranged in the second storage area 106. After the heat dissipation medium is transferred to the first storage area 102, it will also start to cool down, so as to be convenient for use when the liquid needs to be cooled down next time.

[0067] In an extensible manner, the working state of the conveying device can be controlled by the user or by the controller. For example, after the user has finished taking water or there is no cooling demand, a work instruction can be sent to the conveying device to control the conveying device to work, and the heat dissipation medium stored in the second storage area 106 is transferred to the first storage area 102, and the cooling is stopped. Alternatively, after the controller determines that the liquid output after cooling has met the user's needs, the conveying device is controlled to work, and the heat dissipation medium stored in the second storage area 106 is transferred to the first storage area 102, and the cooling is ended.

[0068] In this embodiment, a conveying device is provided in the second storage area 106 for conveying the heat dissipation medium stored in the second storage area 106 to the first storage area 102. The conveying device can realize automatic reflux of the heat dissipation medium, thereby reducing the usage load of the user.

[0069] In an optional embodiment, as shown in FIG. 2 , the second storage area 106 extends in a horizontal direction, the first storage area 102 extends in a vertical direction, and the cooling switch 104 is disposed in a height direction of the first storage area 102 .

[0070] The extension direction of the first storage area 102 is the vertical direction, and the cooling switch 104 is arranged in the height direction of the first storage area 102, which means that it is arranged in the vertical direction. When there are multiple cooling switches 104, each cooling switch 104 is respectively arranged in a different height direction of the first storage area 102. When the first storage area 102 stores a heat dissipation medium, different heights of the first storage area 102 can be reached according to different amounts of the stored heat dissipation medium, and the greater the amount, the higher the height.

[0071] The second storage area 106 extends in the horizontal direction. When the cooling switch 104 is turned on, the heat dissipation medium stored in the first storage area 102 can automatically flow into the second storage area 106 under the action of gravity, without the need to set up other structures to help transfer, which is conducive to simplifying the structure. In addition, based on the structure of this embodiment, after the cooling process is completed, the user can tip the liquid cooling device so that the first storage area 102 is located in the horizontal direction and the second storage area 106 is located in the vertical direction. Therefore, the heat dissipation medium stored in the second storage area 106 can flow into the first storage area 102 under the action of gravity, realizing the reflux of the heat dissipation medium, which is convenient to use.

[0072] In this embodiment, the second storage area 106 extends in a horizontal direction, the first storage area 102 extends in a vertical direction, and the cooling switch 104 is arranged in a height direction of the first storage area 102. This structure can facilitate the flow of the heat dissipation medium between the first storage area 102 and the second storage area 106, which is conducive to improving the convenience of use of the liquid cooling device.

[0073] Illustratively, in one embodiment, the liquid cooling device further includes a cleaning device, which is disposed in the first storage area and / or the second storage area and is used to clean the heat dissipation medium.

[0074] The cleaning device may be arranged in the first storage area to clean the heat dissipation medium in the first storage area to improve the cleanliness of the heat dissipation medium, thereby reducing the impact on the quality of the liquid being cooled when the heat dissipation medium is used for cooling.

[0075] Alternatively, the cleaning device may be disposed in the second storage area to clean the heat dissipation medium in the second storage area. For example, when the heat dissipation medium stored in the second storage area cools the liquid, the heat dissipation medium may be cleaned to reduce the impact on the quality of the liquid. Alternatively, the cleaning device may clean the heat dissipation medium stored in the second storage area before the heat dissipation medium flows back to the first storage area to improve the cleanliness of the heat dissipation medium.

[0076] Alternatively, the cleaning device may be disposed in both the first storage area and the second storage area, so that the heat dissipation medium can be cleaned in both storage areas, thereby enhancing the cleaning effect.

[0077] The type of cleaning device is not limited. For example, the cleaning device can be an ultraviolet disinfection device. The ultraviolet disinfection device disinfects and sterilizes the heat dissipation medium by emitting ultraviolet rays. It is understood that in other embodiments, the cleaning device can also be of other types as long as those skilled in the art consider it feasible.

[0078] Illustratively, in one embodiment, the liquid cooling device further includes a controller, and the controller is connected to the cooling switch.

[0079] When the controller is connected to the cooling switch, the state of the cooling switch can be controlled based on the connected signal, or based on a preset rule. The state of the cooling switch can be controlled to be turned on or off, or to adjust the opening of the cooling switch.

[0080] For example, when the controller receives a signal indicating the need to take cooling liquid, it can control the cooling switch to open so that the first storage area and the second storage area are connected, and the heat dissipation medium stored in the first storage area flows into the second storage area. The heat dissipation medium in the second storage area cools the liquid to provide cooled liquid.

[0081] Alternatively, when the controller controls the cooling switch to be turned on, it starts to time the opening time of the cooling switch. When the opening time of the cooling switch reaches the preset opening time, it means that the cooling requirement has been met, and the cooling switch can be controlled to be turned off to end the cooling. It can be understood that in other embodiments, the controller can also exchange signals with other devices, or control the working status of other devices, etc., which will not be repeated here.

[0082] In this embodiment, the liquid cooling device further includes a controller, and the controller is connected to the cooling switch. The cooling switch can be controlled by the controller, thereby improving the intelligence level of the liquid cooling device.

[0083] In one embodiment, the liquid cooling device further includes an input device connected to the controller, the input device is used to receive a liquid extraction instruction and transmit it to the controller, and the controller is used to control the cooling switch according to the liquid extraction instruction.

[0084] Among them, the input device is a device for interacting with the user. After receiving the user's instructions, the input device can transmit the received user instructions to the controller, so that the controller executes relevant processing according to the user's instructions, such as controlling the cooling switch according to the liquid extraction instruction.

[0085] Specifically, after the input device receives the liquid taking instruction, it indicates that the user needs to take the cooled liquid at this time. In this case, the input device transmits the liquid taking instruction to the controller, and the controller controls the cooling switch to open according to the liquid taking instruction, so that the first storage area and the second storage area are connected, and the heat dissipation medium stored in the first storage area flows into the second storage area, and the heat dissipation medium in the second storage area cools the liquid to provide the cooled liquid. The type of input device is not unique, for example, it can be a button, a touch screen or a voice device, etc., which is not limited here.

[0086] In this embodiment, the liquid cooling device further includes an input device connected to the controller, the input device is used to receive a liquid extraction instruction and transmit it to the controller, and the controller is used to control the cooling switch according to the liquid extraction instruction. Thus, the user can send relevant instructions through the input device so that the controller controls the cooling switch according to the user's needs, thereby improving the convenience and automation of the liquid cooling device.

[0087] In an embodiment, the liquid cooling device further comprises a temperature sensor, which is arranged at the liquid outlet of the liquid outlet channel and connected to the controller. The temperature sensor is used to detect the outlet temperature of the liquid and transmit it to the controller, and the controller is used to control the cooling switch according to the outlet temperature.

[0088] The temperature sensor is arranged at the liquid outlet of the liquid outlet channel, and can be arranged at the side of the liquid outlet close to the liquid, or at the side of the liquid outlet far from the liquid. After the temperature sensor detects the outlet temperature of the liquid, it transmits it to the controller, and the controller analyzes the outlet temperature and controls the cooling switch according to the analysis result.

[0089] For example, after the controller obtains the outlet temperature of the liquid, if it is determined that the outlet temperature of the liquid is too high, more cooling switches can be controlled to open to improve the cooling effect, thereby reducing the outlet temperature of the liquid to meet user needs. Alternatively, after the controller obtains the outlet temperature of the liquid, if it is determined that the outlet temperature of the liquid meets the requirements or is low, the cooling switches can be controlled to close to end the cooling process.

[0090] In this embodiment, the liquid cooling device further includes a temperature sensor, which is disposed at the liquid outlet of the liquid outlet channel and connected to the controller. The temperature sensor is used to detect the outlet temperature of the liquid at the outlet and transmit it to the controller, and the controller is used to control the cooling switch according to the outlet temperature of the liquid. Thus, the state of the cooling switch can be adjusted according to the outlet temperature of the liquid to achieve feedback adjustment of the cooling process and improve the working reliability of the liquid cooling device.

[0091] For example, in one embodiment, the liquid cooling device further comprises a gravity sensor, which is arranged on the liquid cooling device and connected to the controller. The gravity sensor is used to detect the amount of liquid to be cooled and transmit it to the controller, and the controller is used to control the cooling switch according to the amount of liquid.

[0092] Among them, the gravity sensor can be set on the side of the liquid cooling device close to the ground, so as to detect the total liquid volume of the liquid cooling device, and then obtain the liquid volume of the liquid to be cooled in the liquid cooling device. After the gravity sensor detects the liquid volume of the liquid to be cooled, it is transmitted to the controller, and the controller controls the cooling switch according to the liquid volume. For example, the controller can control the number of cooling switches that are opened according to the liquid volume of the liquid to be cooled. The larger the liquid volume of the liquid to be cooled, the more cooling switches the controller controls to be opened, so that more heat dissipation medium is used for cooling to meet the cooling demand; the smaller the liquid volume of the liquid to be cooled, the fewer cooling switches the controller controls to be opened, and the less heat dissipation medium is used for cooling, so as to achieve cooling on demand.

[0093] In this embodiment, the liquid cooling device further includes a gravity sensor, which is disposed in the liquid cooling device and connected to the controller. The gravity sensor is used to detect the amount of liquid to be cooled and transmit it to the controller, and the controller is used to control the cooling switch according to the amount of liquid. In this solution, the amount of liquid can be directly detected by the gravity sensor without manual control of the input liquid amount, and the corresponding amount of heat dissipation medium can be matched to achieve intelligent cooling.

[0094] In one embodiment, the liquid cooling device further includes a switch control circuit, and the controller is connected to the cooling switch via the switch control circuit.

[0095] The controller controls the cooling switch by controlling the switch control circuit. The controller adjusts different signals sent to the switch control circuit to control the working state of the switch control circuit, thereby controlling the state of the cooling switch.

[0096] The structure of the switch control circuit is not unique. For example, in one embodiment, as shown in FIG3 , the switch control circuit includes a transistor Q4, a transistor Q5, a resistor R6, a resistor R7, a resistor R8 and a resistor R9. The control end of the transistor Q4 is connected to the controller through the resistor R6, the first end of the transistor Q4 is connected to the control end of the transistor Q5 through the resistor R7, the first end of the transistor Q5 is connected to the cooling switch through the resistor R8, the second end of the transistor Q4 can be connected to the self-locking circuit or the power supply, the control end of the transistor Q5 is grounded through the resistor R9, and the second end of the transistor Q5 is grounded. The controller can send a signal to the transistor Q4 to control the conduction state of the transistor Q4, and then control the conduction state of the transistor Q5. When the controller obtains the liquid amount of the liquid to be cooled, it can output a corresponding control signal, and can control two switches or one switch in the transistor Q4 and the transistor Q5 to open, and the heat dissipation medium flows out. At this time, the preparation work is completed, and the liquid to be cooled can be poured into the liquid cooling device for cooling.

[0097] In this embodiment, the liquid cooling device further includes a switch control circuit. The controller is connected to the cooling switch via the switch control circuit. The switch control circuit can realize accurate control of the cooling switch.

[0098] Exemplarily, in one embodiment, the liquid cooling device also includes a display device connected to the controller. Among them, the display device can display corresponding content according to the signal received from the controller. Exemplarily, after the controller obtains the liquid amount of the liquid to be cooled, it can output a corresponding display signal to the display device, so that the display device displays the liquid amount of the liquid to be cooled, which is convenient for the user to timely understand or perform secondary confirmation of the liquid amount of the liquid to be cooled. Alternatively, the controller can also send the working time of the liquid cooling device to the display device for display, so that the user can better detect the working status of the liquid cooling device. It can be understood that in other embodiments, the display device can also display other content, as long as those skilled in the art believe that it can be achieved.

[0099] The types of display devices are not limited. For example, in one embodiment, the display device includes a display circuit and a display, and the controller is connected to the display via the display circuit. The controller controls the working state of the display circuit by sending a signal to the display circuit, thereby controlling the working state of the display connected to the display circuit.

[0100] Exemplarily, as shown in FIG4 , the display circuit includes four transistors, the control end of each transistor is connected to the controller, and the second end of each transistor can be connected to a self-locking circuit or a power supply. The display is a display screen, and a display screen has four COM channels and can display four digits. The first end of each transistor is respectively connected to a COM channel of the display screen. The controller can control the four COM channels of the display screen by controlling the four transistors, and then control the display content of the display screen.

[0101] In this embodiment, the display device includes a display circuit and a display, and the controller is connected to the display via the display circuit. The controller can control the working state of the display circuit by sending a signal to the display circuit, thereby controlling the working state of the display connected to the display circuit.

[0102] In one embodiment, the liquid cooling device further comprises a chip peripheral circuit connected to the controller. The chip peripheral circuit is connected to the controller and is used to cooperate with the controller to enable the controller to work normally.

[0103] The structure of the chip peripheral circuit is not unique. For example, in one embodiment, as shown in Figure 5, the chip peripheral circuit includes two filter capacitors and three voltage-dividing resistors. After the two filter capacitors are connected in parallel, one end is connected to the controller, and the self-locking circuit or power supply is connected to play a filtering role. The first ends of the three voltage-dividing resistors are all connected to the input device, for example, three springs of the input device can be connected respectively, and the second ends of the three voltage-dividing resistors are connected to the controller. The three springs use touch control logic, which are a power button, a water increase button, and a water reduction button. The controller recognizes the user command through the signal fed back by the three voltage-dividing resistors, and then performs the corresponding control process. It can be understood that in other embodiments, the structure of the chip peripheral circuit can also be other, as long as those skilled in the art believe that it can be achieved.

[0104] Optionally, in one embodiment, the liquid cooling device further comprises a self-locking circuit connected to the controller. The controller can control the working state of the self-locking circuit. The self-locking circuit can also be connected to other circuits, so that the controller can control the working state of other circuits through the self-locking circuit. For example, the self-locking circuit can be connected to one or more of the display circuit, the switch control circuit, and the chip peripheral circuit, such as connecting the display circuit, the switch control circuit, and the chip peripheral circuit through a VDC port to directly control the working state of the connected circuit.

[0105] Exemplarily, after the controller obtains the liquid extraction completion signal, after a preset waiting time, it indicates that the user has completed the liquid extraction, and the controller can control the self-locking circuit to disconnect, so that the circuits connected to the self-locking circuit lose power and stop working. The value of the preset waiting time is not limited, for example, it can be one minute. Alternatively, after the controller detects the liquid extraction instruction, after a preset working time, it indicates that the liquid cooling device has completed cooling, and the controller controls the self-locking circuit to disconnect, so that the circuits connected to the self-locking circuit lose power and stop working. The value of the preset working time is not limited, for example, it can be three minutes.

[0106] The structure of the self-locking circuit is not unique. For example, in one embodiment, as shown in FIG6 , the self-locking circuit includes a transistor Q1, a triode Q2, a triode Q3, a resistor R1, a resistor R2, a resistor R3, a resistor R4, and a resistor R5. The controller is connected to the control end of the triode Q3 through the resistor R5, and the second end of the triode Q3 is grounded. The first end of the resistor R4 is connected to the control end of the triode Q3, and the second end is grounded. The first end of the triode Q3 is connected to the control end of the transistor Q1 through the resistor R2, and the control end of the transistor Q1 is connected to the first end of the transistor Q1 through the resistor R1. The first end of the transistor Q1 is connected to a DC power supply, and the second end of the transistor Q1 is connected to the output end of the self-locking circuit. The input device is connected to the control end of the triode Q2 through the resistor R3, the first end of the triode Q2 is connected to the DC power supply, and the second end of the triode Q2 is connected to the output end of the self-locking circuit.

[0107] The controller can use a self-locking circuit to achieve the goal that after the cooling liquid is connected, there is no need to manually cut off the power to the liquid cooling device. The liquid cooling device will automatically cut off the power after standing by for one minute. Alternatively, when the user touches the power button, the controller detects the touch signal and controls the transistor of the self-locking circuit to be turned on for three minutes. At this time, the next operation can be carried out. After all operations are completed in three minutes, the power will be automatically cut off.

[0108] In this embodiment, the liquid cooling device further comprises a self-locking circuit connected to the controller. The controller can control the working state of the self-locking circuit. The self-locking circuit can control the states of multiple circuits, thereby improving the automation of the liquid cooling device.

[0109] In addition, in one embodiment, the liquid cooling device further includes an energy storage component connected to the controller. The energy storage component may be a battery. The energy storage component may store electrical energy and use the stored electrical energy to power the controller so that the controller works normally. It is understood that in other embodiments, the energy storage component may also be connected to other devices to power other devices, which is not limited here.

[0110] Illustratively, in one embodiment, the liquid cooling device further comprises a thermoelectric power element, a first side of the thermoelectric power element is arranged in contact with the liquid to be cooled, a second side of the thermoelectric power element is exposed to the air, and the thermoelectric power element is connected to the energy storage element.

[0111] Among them, the thermoelectric power generation device generates electricity based on the temperature difference between the temperature on the first side and the temperature on the second side. The greater the temperature difference, the more electrical energy can be generated; the smaller the temperature difference, the less electrical energy can be generated. The first side of the thermoelectric power generation device is arranged in contact with the liquid to be cooled, and the temperature of the first side is close to the temperature of the liquid. The second side of the thermoelectric power generation device is exposed to the air, and the temperature of the second side is close to the room temperature. As a result, it is very likely that a temperature difference will be generated on both sides of the thermoelectric power generation device, and the thermoelectric power generation device can generate electricity using the temperature difference. In addition, the thermoelectric power generation device is connected to the energy storage device, and the generated electrical energy can be transmitted to the energy storage device for storage, so as to charge the energy storage device.

[0112] In this embodiment, the liquid cooling device further includes a thermoelectric power generation element, a first side of which is in contact with the liquid to be cooled, a second side of which is exposed to the air, and the thermoelectric power generation element is connected to an energy storage element. The thermoelectric power generation element can generate electricity using the temperature difference between the liquid and the room temperature to charge the energy storage element, so that the energy storage element can provide more electrical energy to the connected device, thereby extending the life of the liquid cooling device.

[0113] Illustratively, in one embodiment, the liquid cooling device further includes a fan, which is disposed in the first storage area and is used to cool the heat dissipation medium stored in the first storage area.

[0114] The fan is arranged in the first storage area, and generally the air suction side of the fan is arranged close to the first storage area, and the air outlet side of the fan is arranged far from the first storage area. When the fan is working, the heat in the first storage area can be transferred to the air to help the first storage area to dissipate heat. For example, after the heat dissipation medium in the second storage area cools the liquid, the temperature of the heat dissipation medium increases. After the heat dissipation medium with increased temperature flows back to the first storage area, the fan can help the heat dissipation medium to cool down faster, thereby increasing the frequency of use of the heat dissipation medium.

[0115] In this embodiment, the liquid cooling device also includes a fan, which is arranged in the first storage area and is used to cool the heat dissipation medium stored in the first storage area, thereby increasing the usable frequency of the heat dissipation medium in the first storage area, thereby increasing the cooling frequency of the liquid cooling device.

[0116] In one embodiment, the present application further provides a liquid cooling method, which is implemented based on the liquid cooling device of any of the above embodiments, and can be specifically executed by a controller of the liquid cooling device. As shown in FIG7 , the liquid cooling method includes the following steps:

[0117] Step 702, determining the amount of liquid to be cooled.

[0118] The amount of the liquid to be cooled can be set by the user, for example, the user can set it through an input device. The controller uses the amount of liquid set by the user as the amount of the liquid to be cooled. Alternatively, the amount of the liquid to be cooled can also be detected by other devices, such as a gravity sensor, which is not limited here.

[0119] Step 704, controlling the cooling switch to operate according to the amount of the liquid to be cooled.

[0120] After determining the amount of liquid to be cooled, the cooling switch is controlled to work, for example, whether the cooling switch is working, or the opening of the cooling switch, or the number of opened cooling switches, etc., so as to adjust the amount of heat dissipation medium involved in cooling, so that the cooling result can meet the user's needs. It can be understood that in other embodiments, the liquid cooling device also includes other steps that can be implemented by the controller, which will not be repeated here.

[0121] In this embodiment, after determining the amount of liquid to be cooled, the cooling switch is controlled according to the amount of liquid to be cooled. The cooling switch can be controlled accordingly according to the cooling demand so that a corresponding amount of heat dissipation medium is used for cooling, thereby achieving cooling on demand.

[0122] In one embodiment, the present application further provides a heating device, including a liquid heater and a liquid cooling device as described above. The liquid heater includes but is not limited to a kettle, an oil heater, a milk heater, etc. The liquid cooling device can be arranged on the liquid heater to directly cool the liquid heated by the liquid heater and then flow out from the liquid outlet channel for use by the user. In this case, the liquid outlet channel is a liquid outlet channel shared by the liquid heater and the liquid cooling device. Alternatively, the liquid cooling device can also be arranged separately from the liquid heater, in which case the liquid outlet channel is the liquid outlet channel of the liquid cooling device.

[0123] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, taking the liquid to be cooled as hot water and the heat dissipation medium as fine sand as an example, as shown in FIG8 , the cooling process of the liquid cooling device includes the following steps:

[0124] Step A: Start the cooler and set the amount of water required for cooling.

[0125] Step B, according to the input water volume, match the corresponding sand output volume. If the water volume is small, such as 300ml or 500ml, only one switch is turned on, and only one layer of sand is needed to cool the water to a non-scalding state; if the water volume is large, such as 1L, two switches are turned on to flow out two layers of sand to the filter. Accurately control the sand output volume, use the minimum amount of fine sand, and when the fine sand flows back, reduce the static cooling time, the cooling speed is faster in the same time, and it can be used more times.

[0126] Step C: After all the fine sand has flowed into the filter, pour boiling water into the water inlet directly above, and place a container under the water outlet to catch the cooled water.

[0127] Step D: After receiving the cooling water, place the cooling water device horizontally so that the fine sand can flow back to the sand storage place and the switch will be automatically closed; after the fine sand is left to cool down, it can be used again.

[0128] In addition, the liquid cooling device can be further intelligentized in the following ways:

[0129] 1. Add the function of temperature difference power generation, use the difference between hot water temperature and room temperature to generate electricity, charge the battery, and realize the reuse of the battery without replacing the battery.

[0130] 2. Increase the ventilation function of fine sand and add a micro fan to allow the fine sand heated by conduction heat to flow back to the sand storage area (the first storage area), which can achieve faster cooling and increase the frequency of use.

[0131] 3. Add a gravity sensor, no need to manually control the water input, the gravity sensor directly detects the water volume and matches the corresponding sand output to achieve intelligence.

[0132] 4. Add a temperature sensor at the water outlet to detect the cooling water temperature in real time. If the water temperature needs to be further lowered, the cooling water process can be repeated.

[0133] In order to solve the technical problem of hot water burning the mouth in the prior art, this embodiment uses fine sand to conduct heat, thereby achieving the technical effect of quickly cooling the hot water.
