[0063] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] In order to improve the accuracy of judging whether overflow occurs and reduce safety risks, an embodiment of the present invention provides a smart pot. Figure 1 An intelligent pot provided by an embodiment of the present invention is introduced:

[0065] like Figure 1 As shown, an embodiment of the present invention provides a smart pot, which includes a smart pot cover 101 and a pot body 102. The smart pot cover 101 includes: a temperature control module 110, a temperature sensing module 120, an overflow detection module 130 and a signal processing module 140, wherein the temperature control module 110, the temperature sensing module 120 and the overflow detection module 130 are all connected to the signal processing module 140.

[0066] The temperature control module 110 is used to control the signal processing module 140 to be in a working state when the temperature in the pot body 102 is detected to be greater than a preset temperature threshold. When the temperature in the pot body 102 is detected to be not greater than the preset temperature threshold, the signal processing module 140 is controlled to be in a sleeping state.

[0067] The temperature sensing module 120 is used to detect a temperature signal corresponding to the temperature in the pot body 102 and output the temperature signal to the signal processing module 140 .

[0068] The pot overflow detection module 130 is used to detect a pot overflow signal in the pot body 102 and output the pot overflow signal to the signal processing module 140. The pot overflow signal is a signal indicating whether the pot overflow occurs in the pot body 102.

[0069] When the signal processing module 140 is in working state, the signal processing module 140 is used to send the temperature signal and the overflow signal to the heating device corresponding to the smart pot, so that the heating device adjusts the operating power based on the temperature signal and the overflow signal.

[0070] It can be seen that in this embodiment, the temperature control module can control the signal processing module to be in a working state when the temperature is high and in a sleeping state when the temperature is low, according to the relationship between the temperature and the preset temperature threshold, so as to save electric energy. In addition, the temperature signal and the overflow signal can be sent to the heating device, so that the heating device can adjust the operating power according to the temperature signal and the overflow signal, so as to accurately determine whether the overflow occurs and reduce the safety risk. In other words, the embodiment of the present invention provides a smart pot with reliable overflow detection and energy saving.

[0071] As an implementation manner of the embodiment of the present invention, the heating device may be an induction cooker. The induction cooker may include a control module and a signal receiving module. The control module is connected to the signal receiving module.

[0072] The signal receiving module is used to receive temperature signals and overflow signals.

[0073] The control module is used to adjust the operating power of the induction cooker based on the temperature signal. In one embodiment, the corresponding relationship between the temperature range and the operating power is pre-stored, and the operating power to be adjusted corresponding to the temperature signal can be determined based on the temperature range in which the temperature value corresponding to the temperature signal is located and the corresponding relationship between the temperature range and the operating power, so as to adjust the operating power of the induction cooker to the operating power to be adjusted.

[0074] When the operating power to be adjusted is greater than the current operating power, it is equivalent to increasing the operating power of the induction cooker. When the operating power to be adjusted is not greater than the current operating power, it is equivalent to reducing the operating power of the induction cooker.

[0075] In another embodiment, the correspondence between the temperature interval and the power adjustment value is pre-stored, and the power adjustment value to be adjusted corresponding to the temperature signal can be determined based on the temperature interval in which the temperature value corresponding to the temperature signal is located and the correspondence between the temperature interval and the power adjustment value.

[0076] The power adjustment value to be adjusted can be a positive value or a negative value. When the power adjustment value to be adjusted is a positive value, it is equivalent to increasing the operating power of the induction cooker. When the power adjustment value to be adjusted is a negative value, it is equivalent to reducing the operating power of the induction cooker. This is reasonable.

[0077] The correspondence between the temperature interval and the operating power and the correspondence between the temperature interval and the power adjustment value can be determined based on the operating mode of the induction cooker. That is, the correspondence between the temperature interval and the operating power and the correspondence between the temperature interval and the power adjustment value corresponding to different operating modes may be different. In this way, the accuracy of adjusting the operating power of the induction cooker can be improved.

[0078] The control module is further configured to control the induction cooker to stop operating when the temperature value corresponding to the temperature signal is greater than a preset overflow temperature and the overflow signal indicates that overflow has occurred, wherein the preset overflow temperature is greater than a preset temperature threshold. The preset overflow temperature can be set according to actual use requirements, for example, the preset overflow temperature can be set to 90°C, 93°C, 95°C, etc.

[0079] When the temperature value corresponding to the temperature signal is greater than the preset overflow temperature and the overflow signal indicates that overflow has occurred, it means that the temperature inside the pot is high and overflow has occurred. Therefore, the induction cooker can be controlled to stop running, thereby reducing safety risks.

[0080] When the temperature value corresponding to the temperature signal is not greater than the preset overflow temperature, and the overflow signal indicates that overflow has occurred, it means that overflow has not occurred. Therefore, the control module can adjust the operating power of the induction cooker based on the temperature signal.

[0081] When the temperature value corresponding to the temperature signal is greater than the preset overflow temperature, and the overflow signal indicates that overflow has not occurred, it means that overflow has not occurred, and therefore, the control module can reduce the operating power of the induction cooker.

[0082] When the temperature value corresponding to the temperature signal is not greater than the preset overflow temperature, and the overflow signal indicates that overflow has not occurred, it means that overflow has not occurred. Therefore, the control module can adjust the operating power of the induction cooker based on the temperature signal.

[0083] It can be seen that in this embodiment, the operating power of the induction cooker can be accurately adjusted according to the temperature signal and the overflow signal, thereby reducing the safety risk.

[0084] As an implementation of the embodiment of the present invention, the temperature control module includes a temperature control switch, one end of the temperature switch is connected to the signal processing module, and the other end of the temperature switch is grounded;

[0085] The temperature control switch is used to close when the temperature is greater than the preset temperature threshold, and output a low level to the signal processing module to control the signal processing module to be in a working state;

[0086] The temperature control switch is also used to disconnect when the temperature is not greater than the preset temperature threshold, so as to control the signal processing module to be in a sleep state. The preset temperature threshold can be set according to actual use requirements, for example, the preset temperature threshold can be set to 40°C, 50°C, 60°C, etc.

[0087] In one embodiment, one end of the temperature-controlled switch can be connected to one end of a temperature-controlled current-limiting resistor, and the other end of the temperature-controlled current-limiting resistor can be connected to the signal processing module. The resistance value of the temperature-controlled current-limiting resistor can be set according to actual use requirements.

[0088] When the preset temperature threshold is 50°C, Figure 2 As shown, it includes a temperature controlled switch 201, a temperature controlled current limiting resistor R1 and a signal processing module 140. The other end of the temperature controlled switch 201 is grounded, one end of the temperature controlled switch 201 is connected to one end of the temperature controlled current limiting resistor R1, and the other end of the temperature controlled current limiting resistor R1 is connected to the signal processing module 140. The resistance value of the temperature controlled current limiting resistor R1 can be 1 kilo-ohm.

[0089] When the temperature reaches 50° C., the temperature control switch 201 is closed, that is, the temperature control switch 201 is short-circuited, and a falling edge signal can be output to the signal processing module 140 , so that the signal processing module 140 can be in a working state.

[0090] When the temperature is greater than 50° C., the temperature control switch 201 is continuously closed, and the temperature control switch 201 can continuously output a low level to the signal processing module 140 , so that the signal processing module 140 can always be in a working state.

[0091] It can be seen that in this embodiment, the temperature control switch can control the signal processing module according to the relationship between the temperature and the preset temperature threshold. Specifically, the temperature control switch can control the signal processing module to be in a working state when the temperature is high and in a sleeping state when the temperature is low, according to the relationship between the temperature and the preset temperature threshold, thereby saving electric energy.

[0092] As an implementation manner of an embodiment of the present invention, the above-mentioned smart pot cover further includes a button, one end of the button is grounded, and the other end of the button is connected to the signal processing module;

[0093] When the button is subjected to a pressure greater than a preset pressure threshold, a low level is output to the signal processing module to control the signal processing module to be in a working state. The preset pressure threshold can be set according to actual use requirements.

[0094] In one embodiment, the other end of the button can be connected to one end of the button current limiting resistor, and the other end of the button current limiting resistor can be connected to the signal processing module, wherein the resistance value of the button current limiting resistor can be consistent with the resistance value of the temperature-controlled current limiting resistor, and can also be set according to actual usage requirements.

[0095] like Figure 3 As shown, one end of the button 301 is grounded, the other end of the button 301 is connected to one end of the button current limiting resistor R2, and the other end of the button current limiting resistor R2 is connected to the signal processing module 140. When the button 301 is subjected to a pressure greater than a preset pressure threshold, the button 301 is closed and a low level can be output to the signal processing module 140, so that the signal processing module 140 is in a working state. The resistance value of the button current limiting resistor R2 can be 1 kilo-ohm.

[0096] It can be seen that in this embodiment, the user can actively control the signal processing module to be in working state by pressing buttons according to actual usage needs, without waiting for the temperature control switch to control, which can meet the user's usage needs.

[0097] As an implementation mode of an embodiment of the present invention, the above-mentioned smart pot cover also includes a battery, and the battery is used to provide electrical energy; wherein one pole of the battery can be connected to the power supply end, and the other pole of the battery is grounded.

[0098] The smart pot cover also includes a light prompt module, and the light prompt module and the battery are both connected to the signal processing module;

[0099] The light prompt module includes a light of a first color and a light of a second color;

[0100] The signal processing module is also used to control the light of the first color to flash a preset number of times when the signal processing module enters a working state; wherein the preset number of flashes can be set according to actual usage requirements, for example, the preset number of flashes can be 1, 3, 4, etc.

[0101] The signal processing module is further used to control the light of the second color to light up when the overflow signal indicates that the overflow occurs. In order to allow the user to know the overflow in time, the light of the second color can be controlled to be always on.

[0102] The signal processing module is also used to control the light of the first color to not light up when the power of the battery is lower than a preset power and the key is subjected to a pressure greater than a preset pressure threshold. In this way, the user can know the battery power status in time and replace the battery.

[0103] For example, Figure 4As shown, one end of the first color lamp 401 and one end of the second color lamp 402 are both connected to the power supply terminal VCC, the other end of the first color lamp 401 is connected to one end of the first light current limiting resistor R3, and the other end of the second color lamp 402 is connected to one end of the second light current limiting resistor R4. The other end of the first light current limiting resistor R3 and the other end of the second light current limiting resistor R4 are both connected to the signal processing module 140. The first color lamp 401 can be green, and the second color lamp 402 can be red. Figure 4 Only different grayscales are used to illustrate, and specific colors can be set according to actual usage requirements.

[0104] When the signal processing module 140 is in working state, the signal processing module 140 can control the first color light 401 (green) to flash. When the overflow signal indicates that the overflow occurs, the signal processing module 140 can control the second light current limiting resistor 405 (red) to be always on. If the user presses the button and the first color light 401 (green) does not light up, it means that the battery power is lower than the preset power, so the user can replace the battery.

[0105] The resistance value of the first light current limiting resistor R3 and the resistance value of the second light current limiting resistor R4 can be consistent with the resistance value of the temperature control current limiting resistor, and can also be set according to actual use requirements. The resistance value of the first light current limiting resistor R3 can be 1 kilo ohm. The resistance value of the second light current limiting resistor R4 can be 1 kilo ohm.

[0106] As an implementation method of an embodiment of the present invention, the above-mentioned overflow signal includes a first overflow signal and a second overflow signal. The overflow detection module includes a first overflow detection unit and a second overflow detection unit, the first overflow detection unit includes an anti-overflow sheet, and the second overflow detection unit includes an anti-overflow probe. The first overflow detection unit and the second overflow detection unit have different measurement principles.

[0107] The first overflow detection unit is used to detect the first overflow signal based on the charge change corresponding to the overflow prevention sheet. The second overflow detection unit is used to detect the second overflow signal based on the resistance change corresponding to the overflow prevention probe. The overflow prevention probe includes a first overflow prevention probe and a second overflow prevention probe.

[0108] The second overflow detection unit is less affected by temperature and humidity. When the overflow occurs to a lesser extent (for example, when foam overflows), although the resistance change corresponding to the overflow prevention probe is small, the second overflow signal will be detected relatively quickly.

[0109] In actual use, the second pot overflow signal can be detected first, and then sent to the induction cooker, so that the induction cooker stops running. In this way, the induction cooker can be stopped when the degree of pot overflow is relatively minor.

[0110] When the first pot overflow signal and the second pot overflow signal are detected at the same time, it indicates that the pot overflow situation is more serious. In this case, an alarm module can be set to control the induction cooker to stop running and play an alarm so that the user can come in time.

[0111] As an implementation mode of an embodiment of the present invention, the first overflow detection unit also includes an overflow current limiting resistor, wherein the resistance value of the overflow current limiting resistor can be consistent with the resistance value of the temperature control current limiting resistor, and can also be set according to actual usage requirements.

[0112] Both ends of the overflow prevention sheet are connected to one end of the overflow current limiting resistor, and the other end of the overflow current limiting resistor is connected to the signal processing module. Figure 5 As shown, the first overflow detection unit includes an anti-overflow sheet 501 and an overflow current limiting resistor R5, the anti-overflow sheet 501 is connected to one end of the overflow current limiting resistor R5, and the other end of the overflow current limiting resistor R5 is connected to the signal processing module 140. The resistance value of the overflow current limiting resistor R5 can be 1 kilo-ohm.

[0113] As an implementation method of the embodiment of the present invention, Figure 6 As shown, the second overflow detection unit includes a first anti-overflow probe P1, a second anti-overflow probe P2, a first voltage-dividing resistor R6, and a second voltage-dividing resistor R7. The resistance value of the first voltage-dividing resistor R6 and the resistance value of the second voltage-dividing resistor R7 can be set according to actual use requirements. For example, the resistance value of the first voltage-dividing resistor R6 can be 562 kilo-ohms. The resistance value of the second voltage-dividing resistor R7 can be 4.7 megohms.

[0114] The first anti-overflow probe P1 is connected to one end of the first voltage-dividing resistor R6, the other end of the first voltage-dividing resistor R6 is connected to the power supply terminal VCC, one end of the first voltage-dividing resistor R6 is also connected to one end of the second voltage-dividing resistor R7, the second anti-overflow probe P2 is connected to the other end of the second voltage-dividing resistor R7, and the other ends of the second anti-overflow probe P2 and the second voltage-dividing resistor R7 are also grounded;

[0115] One end of the first voltage-dividing resistor R6 , the first anti-overflow probe P1 , and one end of the second voltage-dividing resistor R7 are all connected to the signal processing module 140 .

[0116] As an implementation method of the embodiment of the present invention, Figure 6As shown, the second overflow detection unit further includes a first protection resistor R8, a second protection resistor R9, a current limiting resistor R10, a filter capacitor C1, a first diode D1 and a second diode D2; the first diode D1 is used to prevent a voltage higher than the power supply terminal VCC from entering, thereby avoiding damage to the circuit. The second diode D2 is used to prevent a signal lower than the ground from entering.

[0117] The resistance value of the first protection resistor R8 and the resistance value of the second protection resistor R9 can be set according to actual use requirements. For example, the resistance value of the first protection resistor R8 and the resistance value of the second protection resistor R9 can both be 10 kilo-ohms. The resistance value of the current limiting resistor R10 can be consistent with the resistance value of the temperature-controlled current limiting resistor, and can also be set according to actual use requirements.
