Description

Temperature sensing glass ball, temperature sensing alarm circuit and electronic device

The present invention relates to the field of electronic circuits, and in particular to a temperature-sensitive glass ball, a temperature-sensitive alarm circuit and an electronic device.

In many fire-related casualties, many fires occur at night, and people may be burned to death while sleeping. Nowadays, many old residential communities and newly built residential buildings do not have automatic fire alarms and smoke and heat fire detectors installed indoors. When a fire occurs, sleeping people miss the best time to escape the fire scene because there is no effective fire detection and alarm device, resulting in a large number of fire casualties. In today's society, mobile phones have become a must-have electronic product for everyone. Whether it is day or night, mobile phones are basically not left by their side, and mobile phones have the basic functions of vibrating ringtones and directly communicating with emergency contacts. In addition, current temperature-sensitive glass balls are non-conductive, so it is necessary to set additional conductive elements on the temperature-sensitive glass balls so that the temperature-sensitive glass balls can be connected to the temperature-sensitive alarm circuit. Therefore, it is necessary to provide a mobile phone with a temperature-sensitive alarm function to detect and alert users in time when a fire occurs.

In view of the above, it is necessary to provide a temperature-sensitive glass ball, a temperature-sensitive alarm circuit and an electronic device to detect and alert users in time when a fire occurs, thereby avoiding fire-related casualties.

The first aspect of this application provides a temperature-sensitive glass ball, which is electrically conductive.

Preferably, the outer surface/inner surface of the temperature-sensitive glass ball is coated with a conductive material, or the temperature-sensitive glass ball is sealed inside to contain a vaporizable conductive liquid.

The second aspect of the present application provides a temperature sensing alarm circuit, comprising a temperature sensing glass ball, a power supply voltage, an input resistor and a ground terminal, wherein the temperature sensing glass ball comprises a first end and a second end, wherein the first end is connected to the power supply voltage via the input resistor, and the second end is connected to the ground terminal, and the temperature sensing alarm circuit further comprises a SOC circuit and an alarm, wherein the SOC circuit is connected to the alarm, and the SOC circuit is connected to the first end of the temperature sensing glass ball and the SOC circuit is used to detect the voltage value of the first end of the temperature sensing glass ball. When the ambient temperature does not reach the bursting temperature of the temperature-sensitive glass ball, the temperature-sensitive glass ball will not burst, the circuit between the power voltage and the temperature-sensitive glass ball is connected, and the voltage at the first end is low; when the ambient temperature reaches the bursting temperature of the temperature-sensitive glass ball, the temperature-sensitive glass ball bursts, the circuit between the power voltage and the temperature-sensitive glass ball is disconnected, and the voltage at the first end is high. When the SOC circuit detects that the voltage value at the first end of the temperature-sensitive glass ball is high, it controls the alarm to sound an alarm.

Preferably, the interior of the temperature-sensitive glass ball is sealed with a vaporizable conductive liquid, and the conductive liquid is electrically connected to the first end and the second end of the temperature-sensitive glass ball.

Preferably, a glass tube filled with conductive liquid is disposed inside the temperature-sensitive glass ball, and the conductive liquid is electrically connected to the first end and the second end of the temperature-sensitive glass ball through the glass tube filled with conductive liquid.

Preferably, the conductive liquid is electrically connected to the first end and the second end of the temperature-sensitive glass ball via wires.

Preferably, the interior of the temperature-sensitive glass ball contains a vaporizable liquid in a sealed manner, the outer surface/inner surface of the temperature-sensitive glass ball is coated with a conductive material, and the first end and the second end of the temperature-sensitive glass ball are respectively connected to the outer surface/inner surface of the temperature-sensitive glass ball.

Preferably, the temperature sensing alarm circuit also includes a vibration module, which is connected to the SOC circuit. When the SOC circuit detects that the voltage value at the first end of the temperature sensing glass ball is at a high level, the vibration module is controlled to vibrate.

The third aspect of this application provides an electronic device, which includes the above-mentioned temperature sensing alarm circuit.

Preferably, the electronic device further includes a communication module, which is connected to the SOC circuit of the temperature sensing alarm circuit. When the SOC circuit detects that the voltage value of the first end of the temperature sensing glass ball is high, it detects whether a user's instruction to turn off the alarm is received within a preset time. When the user's instruction to turn off the alarm is not received within the preset time, the SOC circuit obtains the location information of the electronic device, controls the communication module to contact a preset emergency contact, and sends the obtained location information of the electronic device to the contact.

In this case, when a fire occurs, the temperature-sensitive glass ball detects whether the ambient temperature exceeds the bursting temperature of the temperature-sensitive glass ball. When the ambient temperature exceeds the bursting temperature of the temperature-sensitive glass ball, the SOC circuit sends a control command to control the alarm device to sound an alarm, thereby reminding the user in time to avoid fire casualties.

Please refer to Figure 1, which is a schematic diagram of a temperature sensing alarm circuit 1 in an embodiment of the present invention. In this embodiment, the temperature sensing alarm circuit 1 at least includes a temperature sensing glass ball 11, a power voltage 12, an input resistor 13, a ground terminal 14, a SOC (System On Chip) circuit 15 and an alarm 16. In this embodiment, the temperature sensing glass ball 11 includes a first end 111 and a second end 112. The first end 111 of the temperature sensing glass ball 11 is connected to the power voltage 12 via the input resistor 13. In this embodiment, the input resistor is 100kΩ and the power voltage 12 is 1.8V. The second end 112 of the temperature sensing glass ball 11 is connected to the ground terminal 14. The SOC circuit 15 is connected to the alarm 16. The SOC circuit 15 is connected to the first end 111 of the temperature-sensitive glass ball 11 and is used to detect the voltage value of the first end 111 of the temperature-sensitive glass ball 11. In this embodiment, when a fire occurs, the ambient temperature gradually increases. When the ambient temperature does not reach the explosion temperature of the temperature-sensitive glass ball 11, the temperature-sensitive glass ball 11 will not explode, the circuit between the power voltage 12 and the temperature-sensitive glass ball 11 is connected, and the voltage of the first end 111 of the temperature-sensitive glass ball 11 is low. When the ambient temperature reaches the bursting temperature of the temperature-sensitive glass ball 11, the temperature-sensitive glass ball 11 bursts, the circuit between the power voltage 12 and the temperature-sensitive glass ball 11 is disconnected, the voltage of the first end 111 of the temperature-sensitive glass ball 11 is high, and the SOC circuit 15 controls the alarm 16 to sound an alarm when it detects that the voltage value of the first end 111 of the temperature-sensitive glass ball 11 is high. Therefore, in this case, when a fire occurs, the temperature-sensitive glass ball 11 detects whether the ambient temperature exceeds the bursting temperature of the temperature-sensitive glass ball 11, and when the ambient temperature exceeds the bursting temperature of the temperature-sensitive glass ball 11, the SOC circuit 15 sends a control instruction to control the alarm 16 to sound an alarm, thereby timely reminding the user to avoid fire casualties.

The conductive liquid 113 is electrically connected to the first end 111 and the second end 112 of the temperature sensing glass ball 11. In one embodiment, a glass tube 114 filled with conductive liquid is provided in the temperature sensing glass ball 11, and the conductive liquid 113 is electrically connected to the first end 111 and the second end 112 of the temperature sensing glass ball 11 through the glass tube 114 filled with conductive liquid. In this embodiment, the conductive liquid 113 is a gasifiable conductive liquid (such as mercury) or a mixture of a gasifiable conductive liquid and a conductive material. In another embodiment, the conductive liquid 113 is electrically connected to the first end 111 and the second end 112 of the temperature-sensitive glass ball 11 respectively through wires. In this embodiment, different conductive liquids can be distinguished by different colors. For example, the conductive liquid can be divided into orange conductive liquid, red conductive liquid, yellow conductive liquid, and green conductive liquid, wherein the explosion temperature corresponding to the orange conductive liquid is 57°C, the explosion temperature corresponding to the red conductive liquid is 68°C, the explosion temperature corresponding to the yellow conductive liquid is 79°C, and the explosion temperature corresponding to the green conductive liquid is 93°C. In this embodiment, when the ambient temperature reaches the explosion temperature, the conductive liquid 113 expands and explodes the temperature-sensitive glass ball 11, thereby disconnecting the circuit between the power voltage 12 and the temperature-sensitive glass ball 11.

In one embodiment, the interior of the temperature-sensitive glass ball 11 is sealed to contain a vaporizable liquid, and the outer surface/inner surface of the temperature-sensitive glass ball 11 is coated with a conductive material. The first end 111 and the second end 112 of the temperature-sensitive glass ball 11 are respectively connected to the outer surface/inner surface of the temperature-sensitive glass ball 11, so that when the ambient temperature does not reach the bursting temperature of the temperature-sensitive glass ball 11, the circuit between the power supply voltage 12 and the temperature-sensitive glass ball 11 is connected, or when the ambient temperature reaches the bursting temperature of the temperature-sensitive glass ball 11, the circuit between the power supply voltage 12 and the temperature-sensitive glass ball 11 is disconnected. In this embodiment, the vaporizable liquid includes at least alcohol. In other embodiments, the vaporizable liquid may be an organic solution with a high thermal expansion coefficient.

In this embodiment, the alarm 16 is a speaker. When the SOC circuit 15 detects that the voltage value of the first end 111 of the temperature-sensitive glass ball 11 is high, the speaker is controlled to emit a sound to sound an alarm.

In one embodiment, the temperature sensing alarm circuit 1 further includes a vibration module 17. The vibration module 17 is connected to the SOC circuit 15.

In this embodiment, the vibration module 17 is a vibration motor module.

In this embodiment, the electronic device 100 includes the temperature sensing alarm circuit 1 and the communication module 2.

Please refer to FIG. 3, which is a structural schematic diagram of the electronic device 100 in an embodiment of the present invention. The temperature sensing glass ball 11 in the temperature sensing alarm circuit 1 is installed on the back cover 101 of the electronic device 100. Specifically, the temperature sensing glass ball 11 is installed in a sealed container 18, and the sealed container 18 is installed on the back cover 101 of the electronic device 100 near the rear camera. When the SOC circuit 15 detects that the voltage value of the first end 111 of the temperature-sensitive glass ball 11 is at a high level, it detects whether the user has received an instruction to turn off the alarm 16 or the vibration module 17 within the preset time. When the user has not received an instruction to turn off the alarm 16 or the vibration module 17 within the preset time, the SOC circuit 15 obtains the location information of the electronic device 100, controls the communication module 2 to contact the preset emergency contact, and sends the obtained location information of the electronic device 100 to the emergency contact. Therefore, when the user does not find the fire situation because of deep sleep, the preset emergency contact notifies the user, avoiding the occurrence of casualties caused by the user not being notified in time.
