[0019] With the advent of the Internet of Things era, smart home products are becoming increasingly popular. The low power consumption of smart home products is optimized to extend the battery life of smart home products. In the related technologies for optimizing the low power consumption of smart home products (e.g., temperature detection devices), a voltage-boosting process is usually performed through a voltage-stabilizing circuit to generate the required operating voltage to ensure that the temperature detection device can work normally. However, due to the loss of components inside the voltage-stabilizing circuit, the circuit has a high loss, thereby reducing the battery life of the temperature detection device.

[0020] In order to improve the above-mentioned problems, the present application provides a temperature detection device and a temperature detection equipment, wherein the temperature detection device comprises: a power supply battery, a connection detection module, a temperature detection module and a processing module, wherein the first end of the connection detection module is respectively connected to the positive electrode of the power supply battery and the processing module, the second end of the connection detection module is used for grounding, the third end of the connection detection module is connected to the negative electrode of the power supply battery, and the processing module is also connected to the temperature detection module; the power supply battery is used to provide a working voltage for the processing module; the connection detection module is used to control the power supply battery to power the processing module when it is detected that the power supply battery is supplying power normally; the temperature detection module is used to detect the temperature information of the environment and send the temperature information to the processing module; the processing module is used to determine the temperature value of the environment according to the temperature information.

[0021] Therefore, the working voltage output by the power supply battery is directly provided to the processing module through the connection detection module, so that the temperature detection module and the processing module cooperate with each other to complete the temperature detection, without using a voltage stabilizing circuit, so as to reduce power consumption.

[0022] The following is an introduction to the application environment of the cooking control method provided by the embodiment of the utility model.

[0023] See also Figure 1 , Figure 1 Schematic diagram of a temperature detection device provided in an embodiment of the present application. Figure 1 As shown, Figure 1 The temperature detection device 100 includes a power supply battery 110 , a temperature detection module 120 , a processing module 130 and a connection detection module 140 .

[0024] Among them, the first end of the connection detection module 140 is connected to the positive electrode of the power supply battery 110 and the processing module 130 respectively, the second end of the connection detection module 140 is used for grounding, the third end of the connection detection module 140 is connected to the negative electrode of the power supply battery 110, and the processing module 130 is also connected to the temperature detection module 120.

[0025] The power supply battery 110 is used to provide the required working voltage for the processing module 130; the connection detection module 140 is used to control the power supply battery 110 to supply power to the processing module 130 when it is detected that the power supply battery 110 is supplying power normally; the temperature detection module 120 is used to detect the temperature information of the environment and send the temperature information to the processing module 130; the processing module 130 is used to determine the temperature value of the environment according to the temperature information.

[0026] The power supply battery 110 is composed of a plurality of dry cells connected in series. The present application does not limit the number of AAA dry cells connected in series for the power supply battery 110, and the user can flexibly adjust it according to the actual situation. In some embodiments, the number of AAA dry cells connected in series for the power supply battery 110 can be determined based on the voltage corresponding to each AAA dry cell and the minimum operating voltage required by the processing module 130.

[0027] In a specific embodiment, the power supply battery 110 is composed of two AAA dry batteries connected in series. The power supply battery 110 can provide a working voltage of 1.8V-3.2V to the processing module 130. The processing module 130 can work normally when the power supply battery 110 has the lowest working voltage.

[0028] The working voltage output by the power supply battery 110 is controlled by the connection detection module 140 and is directly provided to the processing module 130, without the need for a voltage-boosting circuit to provide the required working voltage to the processing module 130. Since the voltage-stabilizing circuit is reduced, the loss of components inside the voltage-stabilizing circuit is reduced.

[0029] Through the control of the connection detection module 140, the power supply battery 110 provides the required working voltage to the processing module 130, and then the processing module 130 provides the working voltage to the temperature detection module 120. This ensures that the temperature detection module 120 and the processing module 130 can work normally. The temperature detection module 120 obtains the temperature information of the environment, and the processing module 130 determines the temperature value according to the temperature information.

[0030] In some embodiments, the temperature detection device 100 may be applicable to low-power devices such as electronic thermometers, electronic clocks, and temperature sensors, so that the temperature value of a corresponding area or environment can be read with low power consumption through the temperature detection device 100 .

[0031] Further, in some embodiments, see Figure 2 , Figure 2 Schematic diagram of another temperature detection device provided in the embodiment of the present application. Figure 2 As shown, Figure 2 The power supply battery 110 includes multiple battery cells and a connector P1; the first end of the connection detection module 140 is respectively connected to the positive pole of the connector P1 and the processing module 130, the second end of the connection detection module 140 is used for grounding, and the third end of the connection detection module 140 is connected to the negative pole of the connector P1. The multiple battery cells are connected in series, and the connector P1 is used to place multiple battery cells.

[0032] The battery cell may be an AAA dry cell or other dry cells. The connection detection module 140 is used to control the multiple battery cells to supply power to the processing module 120 when detecting that the positive electrodes of the multiple battery cells connected in series are connected to the positive electrode of the connector P1.

[0033] The connector P1 is used to place multiple battery cells, so that the voltages of the multiple battery cells can be output through the positive and negative electrodes of the connector P1 , and the voltages provided by the multiple battery cells can be provided to the processing module 130 through the connection detection module 140 .

[0034] That is, when multiple cells are connected in series in sequence, and the positive electrodes of the multiple cells connected in series are connected to the positive electrode of the connector P1, the multiple cells connected in series supply power to the processing module 120 normally, so that the temperature detection module 120 and the processing module 130 can cooperate with each other to complete the detection of the temperature value. By detecting whether the positive electrodes of the multiple cells connected in series are connected to the positive electrode of the connector P1, the reverse connection of the multiple cells can be avoided.

[0035] Specifically, in some embodiments, see Figure 3 , Figure 3 is a circuit structure diagram of a connection detection module provided in an embodiment of the present application. Figure 3 As shown, the connection detection module 140 includes a connection resistor R1 and a connection switch device Q1, the first end of the connection switch device Q1 is connected to one end of the resistor R1, the other end of the connection resistor R1 is respectively connected to the positive pole of the connector P1 and the processing module 130, the second end of the connection switch device Q1 is used for grounding, and the third end of the connection switch device Q1 is connected to the negative pole of the connector P1.

[0036] Wherein, the connection switch device Q1 can be a metal oxide semiconductor (Metal-Oxide-Semiconductor, MOS) tube, can also be a triode, can also be an insulated gate bipolar transistor (Insu l ated Gate Bipolar Transistor, IGBT), can also be other switch devices with a switch function. Only when the first end of the connection switch device Q1 is connected to the positive electrode of the multiple-section battery cell in series through the connection resistor R1, the connection switch device Q1 will work normally, forming a power supply circuit for the multiple-section battery cell in series to the processing module 130. When the first end of the connection switch device Q1 cannot be connected to the positive electrode of the multiple-section battery cell in series through the connection resistor R1, the connection switch device Q1 cannot work, and the power supply circuit of the multiple-section battery cell in series to the processing module 130 is disconnected.

[0037] Furthermore, in some embodiments, please continue to refer to Figure 3The connection detection module 140 further includes a first filter capacitor C1 and a second filter capacitor C2, and the first filter capacitor C1 and the second filter capacitor C2 are used for energy storage and filtering to convert the working voltage from a sawtooth wave to a DC wave.

[0038] Specifically, two ends of the first filter capacitor C1 and two ends of the second filter capacitor C2 are connected to the positive electrode and the negative electrode of the connector P1 respectively.

[0039] Among them, the first filter capacitor C1 and the second filter capacitor C2 play the role of storing energy, filtering low-frequency signals and filtering high-frequency wave signals, so that the sawtooth wave originally output by the power supply battery 110 becomes a smooth pulsating wave, and then provided to the processing module 130.

[0040] The connection detection module 140 is added to verify whether the power supply battery is reversely connected, so as to avoid interference with the normal operation of the temperature detection device caused by the reverse connection of the power supply battery. The connection detection module 140 filters out low-frequency signals and high-frequency wave signals from the working voltage output by the power supply battery 110, so as to provide a more stable working voltage to the processing module 130.

[0041] In a temperature detection device that generates a required operating voltage by performing a voltage-boosting process through a voltage-stabilizing circuit, the power consumption of the circuit within the temperature detection device mainly comes from the loss of the switching tube, the resistance loss of the inductive element, and the forward voltage drop loss of the diode.

[0042] Specifically, during the conduction period of the switch tube, the switch tube will have a certain conduction resistance, thereby generating conduction loss. This part of the loss increases with the increase of the conduction time. And when the switch tube switches from the on state to the off state, the switch tube will generate a reverse recovery current, so that the circuit will also cause certain losses during the reverse recovery time of the switch tube. The inductor element itself has a certain resistance, and the resistance of the inductor element itself will cause a certain energy loss in the circuit. And this loss increases with the increase of the working current of the inductor. The forward voltage drop of the diode will also cause a certain energy loss.

[0043] Compared with the temperature detection device using a voltage stabilizing circuit, the circuit device provided by the present application is relatively simple and can effectively reduce the loss of the device itself. The present application directly provides the voltage provided by multiple battery cells to the processing module 130 through the continuous detection module 140. The processing module 130 is connected to the temperature detection module 120 to provide the required voltage to the temperature detection module 120 through the processing module 130 to ensure that the temperature detection module 120 can obtain the temperature information of the environment and send the temperature information back to the processing module 130. The processing module 130 determines the temperature value based on the temperature information.

[0044] Specifically, in some embodiments, see Figure 4, Figure 4 is a circuit structure diagram of a temperature detection module provided in an embodiment of the present application. Figure 4 As shown, the temperature detection module 120 includes a thermistor J2, a first voltage-dividing resistor R2 and a second voltage-dividing resistor R3. The first end of the thermistor J2 is respectively connected to the other end of the first voltage-dividing resistor R2 and the processing module 130, the second end of the thermistor J2 is respectively connected to one end of the second voltage-dividing resistor R3 and the processing module 130, one end of the first voltage-dividing resistor R2 is connected to the processing module 130, and the other end of the second voltage-dividing resistor R3 is used for grounding.

[0045] The thermistor J2 may be a negative temperature coefficient (NTC) thermistor. The thermistor J2 has the advantages of high sensitivity (the resistance variation range of the thermistor J2 is large and it is very sensitive to temperature changes), good stability (not easily affected by interference or noise), high reliability (not easily affected by the environment and can still provide stable electrical characteristics in harsh environments such as extreme temperature or humidity), and fast response speed (its internal structure is relatively simple, so its response speed is faster than other types of temperature sensors).

[0046] The first voltage-dividing resistor R2 and the second voltage-dividing resistor R3 play a role in voltage division. By adjusting the resistance values ​​of the first voltage-dividing resistor R2 and the second voltage-dividing resistor R3, the resistance variation range of the thermistor J2 at different temperatures can be changed, thereby achieving accurate measurement and control of temperature, and at the same time, the sensitivity of the thermistor J2 can be adjusted.

[0047] The temperature information is determined by outputting a first detection voltage through the first end of the thermistor J2 and outputting a second detection voltage through the second end of the thermistor J2. The processing module 130 can obtain the temperature information through the first end of the thermistor J2 and the second end of the thermistor J2. The processing module 130 can determine the voltage value at both ends of the thermistor J2 according to the difference between the first detection voltage and the second detection voltage, and can determine the current value of the loop according to the ratio of the second detection voltage to the resistance value of the second voltage-dividing resistor R3. The processing module 130 can calculate the resistance value of the thermistor J2 according to the voltage value and the current value at both ends of the thermistor J2, and then can determine the current temperature value of the thermistor J2 according to the corresponding relationship between the resistance value of the thermistor J2 and the temperature value.

[0048] Further, in some embodiments, please continue to refer to Figure 4The temperature detection module 120 also includes a first current limiting resistor R4 and a second current limiting resistor R5, one end of the first current limiting resistor R4 is connected to the first end of the thermistor J2, and the other end of the first current limiting resistor R4 is connected to the processing module 130; one end of the second current limiting resistor R5 is connected to the second end of the thermistor J2, and the other end of the second current limiting resistor R5 is connected to the processing module 130.

[0049] The first current limiting resistor R4 and the second current limiting resistor R5 play a role in current limiting to limit the current passing through the thermistor J2 to protect the thermistor J2 and the corresponding input port of the processing module 130 from being damaged.

[0050] Furthermore, in some embodiments, please continue to refer to Figure 4 The temperature detection module also includes a third filter module C3 and a fourth filter module C4, one end of the third filter module C3 is connected to the other end of the second current limiting resistor R5, one end of the fourth filter module C4 is connected to the other end of the first current limiting resistor R4, and the other end of the third filter module C3 and the other end of the fourth filter module C4 are used for grounding.

[0051] The third filter module C3 is used to filter the first detection voltage. The fourth filter module C4 is used to filter the second detection voltage so that the processing module 130 can obtain stable first detection voltage and second detection voltage and better receive temperature information.

[0052] As can be seen from the above, the power supply battery 110 provides the operating voltage to the processing module 130, and then the processing module 130 provides the required voltage to the temperature detection module 120 to ensure that the temperature detection module 120 can obtain the temperature information of the environment. More specifically, in some embodiments, please refer to Figure 5 , Figure 5 is a circuit structure diagram of a processing module provided in an embodiment of the present application. Figure 5 As shown, the processing module 130 includes a signal processing chip U1 and a reset resistor R6, the first end of the signal processing chip U1 is connected to the power supply battery 110, the second end, the third end and the fourth end of the signal processing chip U1 are connected to the temperature detection module 120, the fifth end and the sixth end of the signal processing chip U1 are used for grounding, and the seventh end of the signal processing chip U1 is used for grounding.

[0053] The signal processing chip U1 may be a microcontroller unit (MCU) or a system on chip (Soc), etc. For example, a BT Soc or a WI FI Soc, etc. For ease of understanding, the following description is made by taking the signal processing chip U1 as a microcontroller unit as an example.

[0054] The power supply battery 110 is composed of two AAA dry batteries connected in series. The power supply battery 110 can provide a working voltage of 1.8-3.2V to the processing module 130, and the signal processing chip U1 supports a working voltage between 1.8V and 4.3V. That is to say, the signal processing chip U1 can still work normally when the power supply battery 110 is at the lowest working voltage.

[0055] The first end of the signal processing chip U1 is the VBAT pin (pin 16) of the micro control unit, the second end of the signal processing chip U1 is the PC5 pin (pin 22) of the micro control unit, the third end of the signal processing chip U1 is the PC4 pin (pin 23) of the micro control unit, the fourth end of the signal processing chip U1 is the PA4 pin (pin 1) of the micro control unit, the fifth and sixth ends of the signal processing chip U1 are the GND pin (pin 33, pin 6) of the micro control unit, and the seventh end of the signal processing chip U1 is the RSTP pin (pin 14) of the micro control unit.

[0056] The power supply battery 110 provides the operating voltage to the signal processing chip U1 through the VBAT pin (pin 16) of the signal processing chip U1. The PA4 pin (pin 1) of the signal processing chip U1 is connected to the connection detection module 140, and the PA4 pin of the signal processing chip U1 outputs a high level to provide the voltage required by the temperature detection module 120 to ensure that the temperature detection module 120 can work normally, so that the temperature detection module 120 can obtain temperature information.

[0057] Since the signal processing chip U1 is reset at a high level, in order to prevent the signal processing chip U1 from being reset due to a momentary pulse caused by external interference, the seventh terminal of the signal processing chip U1 is connected to the ground terminal through the reset resistor R6, and the level is pulled down through the reset resistor R6, thereby preventing the signal processing chip U1 from being reset due to a momentary pulse caused by some external interference.

[0058] Further, in some embodiments, the processing module 130 also includes a fifth filter capacitor C5, a sixth filter capacitor C6 and a seventh filter capacitor C7, one end of the fifth filter capacitor C5, one end of the sixth filter capacitor C6 and one end of the seventh filter capacitor C7 are respectively connected to the first end of the signal processing chip U1 and the power supply battery 110, and the other end of the fifth filter capacitor C5, the other end of the sixth filter capacitor C6 and the other end of the seventh filter capacitor C7 are used for grounding.

[0059] The fifth filter capacitor C5, the sixth filter capacitor C6 and the seventh filter capacitor C7 play the roles of energy storage (the fifth filter capacitor C5, the sixth filter capacitor C6 and the seventh filter capacitor C7 can store charge and release it when needed to help smooth the fluctuation of input current, reduce the noise in the power supply battery 110, and improve the stability of the temperature detection device 100), filtering (the fifth filter capacitor C5, the sixth filter capacitor C6 and the seventh filter capacitor C7 can absorb high-frequency noise in the power supply battery 110 to ensure the purity of the power supply battery 110 and improve the quality of signal transmission) and decoupling (reducing the power supply current absorption caused by large load capacitance, thereby avoiding noise problems in the circuit).

[0060] That is, the fifth filter capacitor C5, the sixth filter capacitor C6 and the seventh filter capacitor C7 change the working voltage provided by the power supply battery 110 to the processing module 130 from the original sawtooth wave to a smooth pulsating wave so as to be close to direct current.

[0061] In some implementations, the eighth terminal and the ninth terminal of the signal processing chip U1 are connected to the crystal oscillator device Y1, and the crystal oscillator device Y1 provides a clock frequency signal to the signal processing chip U1 to ensure that the signal processing chip U1 can issue instructions normally.

[0062] The eighth terminal of the signal processing chip U1 is the XTAL0 pin (pin 7) of the signal processing chip U1, and the ninth terminal of the signal processing chip U1 is the XTAL1 pin (pin 8) of the signal processing chip U1. Specifically, the X0UT pin of the crystal oscillator device Y1 is connected to the eighth terminal of the signal processing chip U1, the XIN pin of the crystal oscillator device Y1 is connected to the ninth terminal of the signal processing chip U1, and the GND pin of the crystal oscillator device Y1 is used for grounding.

[0063] In order to better transmit signals between the crystal oscillator device Y1 and the signal processing chip U1, a first filter capacitor C8 is connected between the X0UT pin of the crystal oscillator device Y1 and the GND of the crystal oscillator device Y1, and a second filter capacitor C9 is connected between the XIN pin of the crystal oscillator device Y1 and the GND of the crystal oscillator device Y1.

[0064] In some embodiments, the tenth terminal, the eleventh terminal, and the twelfth terminal of the signal processing chip U1 are output terminals of an internal power supply of the signal processing chip U1, and the RF signal is powered through the tenth terminal, the eleventh terminal, and the twelfth terminal of the signal processing chip U1.

[0065] Specifically, the tenth end of the signal processing chip U1 is the LDO_OUT pin (pin 19) of the signal processing chip U1, the eleventh end of the signal processing chip U1 is the BFB pin (pin 18) of the signal processing chip U1, and the twelfth end of the signal processing chip U1 is the BSW pin (pin 17) of the signal processing chip U1. The tenth end of the signal processing chip U1 is connected to the first capacitor C10, the eleventh end and the twelfth end of the signal processing chip U1 are respectively connected to the two ends of the first inductor L1, the other end of the first inductor L1 is also connected to one end of the second capacitor C11, and the other end of the first capacitor C10 and the other end of the second capacitor C11 are used for grounding.

[0066] See also Figure 6 , Figure 6 2 is a schematic diagram of a temperature detection device provided in an embodiment of the present application. The temperature detection device 200 includes: a display module 210 and the above-mentioned temperature detection device 100. Specifically:

[0067] The display module 210 is used to display the temperature value detected by the temperature detection device.

[0068] The temperature detection device 100 determines the temperature information of the environment through the internal circuit, for example, the power supply module, the connection detection module, the processing module and the temperature detection module inside the temperature detection device 100 cooperate with each other to determine the temperature information of the environment. The temperature detection device 100 then sends the determined temperature information of the environment to the display module 210, and the display module 210 displays the temperature information of the environment so that the user can obtain the temperature of the environment through the display module 210 at any time.

[0069] Furthermore, since the temperature detection device 100 uses a circuit with relatively low power consumption, the service life of the temperature detection device 100 can be effectively prolonged, and the user does not need to frequently replace the battery cell of the temperature detection device 100, thereby improving the user experience.

[0070] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-mentioned device can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.
