Description

Technical Field

[0001] This utility model relates to the field of power cord technology, specifically a power plug cord with gas detection function. Background Technology

[0002] A power plug is a type of electrical wiring accessory, attached to the end of the power cable that connects to an electrical appliance. It is a connector used to plug into a socket. Typically, electricity in homes or factories is supplied through sockets; by inserting the plug of an electrical appliance into these sockets, power is supplied to the appliance to enable it to operate.

[0003] Current power plugs and cords have a relatively simple function, serving only as a power connection. However, when both gas leaks and equipment leakage occur simultaneously in the environment, a single-function module can only respond to its corresponding risk. The gas alarm only triggers the alarm but cannot cut off the power, and the leakage protection module cannot detect the dangerous gas condition. The two lack information exchange and linkage mechanisms. Before the gas leak reaches the explosive limit, if an electric spark is generated at the leakage point, the split system cannot coordinate to control the power cut-off, still posing a risk of a deflagration accident.

[0004] In light of this, we are launching a power plug cable with gas detection functionality. Utility Model Content

[0005] The purpose of this invention is to provide a power plug cable with gas detection function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power plug cable with gas detection function, comprising: a detection box, a gas sensor, and a microcontroller chip;

[0008] The gas sensor is mounted on the top of the circuit board, and a buzzer is mounted on the top of the circuit board to one side of the gas sensor.

[0009] The microcontroller chip is mounted on the surface of the circuit board, and a leakage protection module for cutting off the power supply when there is a circuit leakage is provided on the side of the circuit board where the gas sensor and the buzzer are located.

[0010] The bottom of the detection box is provided with an installation structure. The installation structure is configured with a connecting block, an elastic column and an elastic buckle to make the elastic buckle lock into the inside of the detection box.

[0012] Preferably, the positioning groove has a conductive groove inside for inserting a conductive post, and the bottom of the connecting block is connected to a wire.

[0013] Preferably, a fan is connected to the surface of the circuit board. The fan and the heat dissipation holes on the surface of the detection box work together. When the fan is running, the side holes on the side of the detection box allow outside air to enter (not shown in the figure), which accelerates the airflow and dissipates the heat generated by the circuit board through the heat dissipation holes to the outside of the detection box, thereby reducing the temperature of the circuit board.

[0014] Preferably, the surface of the detection box is provided with heat dissipation holes, which are integrally formed with the detection box. At the same time, the heat dissipation holes can also make the sound of the buzzer louder.

[0015] Preferably, an indicator light is connected to one side of the circuit board, and the indicator light extends through the surface of the detection box. The indicator light may display green when working normally, and red when a fault or abnormality occurs, so that users can intuitively understand the operation of the plug wire. A reset switch is connected to the side of the fan on the surface of the circuit board, and the reset switch extends through the surface of the detection box.

[0016] Preferably, the circuit board has a through hole A on its surface and the detection box has a through hole B inside. The through hole A and the through hole B are aligned. The alignment of the through hole A on the surface of the circuit board and the through hole B inside the detection box may be used for mounting the circuit board and the detection box together with bolts.

[0017] Preferably, positioning posts for fixing the cover are connected at the four corners of the inner sidewall of the mounting groove. The positioning posts are used to fix the cover on the top of the detection box by bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) By integrating functions such as gas detection and leakage protection, the gas detection function can detect harmful gas leaks in the environment in a timely manner, avoiding serious accidents such as poisoning and explosion caused by gas leaks; the leakage protection module can cut off the power supply at the moment of circuit leakage, effectively preventing electric shock accidents, providing users with comprehensive power safety protection, and improving safety during use.

[0020] (2) Through the combined design of connecting blocks, elastic columns and elastic buckles, the connection between the wire and the detection box is firm and reliable, not easy to loosen, and the stability of power transmission is guaranteed.

[0021] (3) The heat dissipation system composed of a fan and heat dissipation holes can effectively reduce the temperature of the circuit board, extend the service life of electronic components, reduce equipment failures caused by overheating, and ensure the stable operation of the power plug for a long time.

[0022] (4) The buzzer and indicator light provide dual sound and light alarms, which can effectively remind users even in noisy or dim environments. The indicator light can display the working status intuitively through different colors, green for normal and red for alarm, so that the fault type can be quickly determined without additional equipment.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a power plug with gas detection function, including: a detection box 1, the inside of the detection box 1 is provided with an installation groove 11, the inside of the installation groove 11 is provided with a circuit board 15, the back of the detection box 1 is provided with a pin 22, the pin 22 and the detection box 1 are integrally formed, the pin 22 is inserted into the power socket, thereby establishing a connection with an external power source.

[0032] Gas sensor 16 is disposed on the top of circuit board 15, and a buzzer 17 is disposed on the top of circuit board 15 on one side of gas sensor 16.

[0033] The microcontroller chip 20 is disposed on the surface of the circuit board 15. On the side of the gas sensor 16 and the buzzer 17, the surface of the circuit board 15 is provided with a leakage protection module 18 for cutting off the power supply when there is a circuit leakage. The leakage protection module 18 will quickly detect the abnormal change in current and immediately activate the function of cutting off the power supply to prevent electric shock accidents or electrical fires caused by leakage, and protect the personal safety of users and the safety of electrical equipment.

[0034] The bottom of the detection box 1 is provided with an installation structure. The connection block 5, elastic column 6 and elastic buckle 7 of the installation structure are arranged in a coordinated manner so that the elastic buckle 7 is locked inside the detection box 1.

[0035] The installation structure includes a positioning groove 9 at the bottom of the detection box 1, which is integrally formed with the detection box 1. The connecting block 5 is inserted into the interior of the positioning groove 9. The elastic column 6 is connected to the top two sides of the connecting block 5, which is integrally formed with the connecting block 5. The elastic buckle 7 is connected to the surface of the elastic column 6, which is integrally formed with the elastic column 6. The interior of the detection box 1 has a slot 14 on the side of the positioning groove 9 for engaging the elastic buckle 7, which is integrally formed with the detection box 1.

[0036] The positioning groove 9 has a conductive groove 10 for inserting conductive posts, and the bottom of the connecting block 5 is connected to a wire 8.

[0037] A fan 19 is connected to the surface of the circuit board 15. The fan 19 and the heat dissipation holes 3 on the surface of the detection box 1 work together. When the fan 19 is running, the side hole on the side of the detection box 1 allows outside air to enter (not shown in the figure), accelerates the air flow, and discharges the heat generated by the circuit board 15 through the heat dissipation holes 3 to the outside of the detection box 1, thereby reducing the temperature of the circuit board 15.

[0038] The surface of the detection box 1 is provided with heat dissipation holes 3, which are integrally formed with the detection box 1. At the same time, the heat dissipation holes 3 can also make the sound of the buzzer 17 louder.

[0039] An indicator light 4 is connected to one side of the surface of the circuit board 15, and the indicator light 4 extends through the surface of the detection box 1. When working normally, the indicator light 4 may show green, and when a fault or abnormality occurs, it will show red, so that users can intuitively understand the operation of the plug wire. A reset switch 2 is connected to the side of the fan 19 on the surface of the circuit board 15, and the reset switch 2 extends through the surface of the detection box 1.

[0040] The circuit board 15 has a through hole A21 on its surface and the detection box 1 has a through hole B13 inside. The through hole A21 and the through hole B13 are aligned. The alignment of the through hole A21 on the surface of the circuit board 15 and the through hole B13 inside the detection box 1 may be used for mounting the circuit board 15 and the detection box 1 together with bolts.

[0041] The four corners of the inner sidewall of the mounting groove 11 are connected to positioning posts 12 for fixing the cover. The positioning posts 12 are used to fix the cover on the top of the detection box 1 by bolts.

[0042] Specifically, when using this power plug with gas detection function, first insert the pin 22 on the back of the detection box 1 into the power socket to establish a connection with the external power source and power the entire plug system. The mounting structure at the bottom of the detection box 1 is used to connect the wire 8. The connecting block 5 is inserted into the positioning groove 9 at the bottom of the detection box 1. The elastic buckle 7 on the elastic post 6 engages with the slot 14 inside the detection box 1 to achieve a stable connection between the wire 8 and the detection box 1. The conductive groove 10 in the positioning groove 9 is used to insert the conductive post to ensure that the power is smoothly transmitted from the detection box 1 to the wire 8, thereby powering the electrical equipment.

[0043] The gas sensor 16 on the top of the circuit board 15 is in continuous operation, monitoring the gas composition and concentration in the surrounding environment in real time. When the gas sensor 16 detects a specific harmful gas (such as carbon monoxide, natural gas leak, etc.) and its concentration reaches a preset threshold, the gas sensor 16 will convert the detected gas signal into an electrical signal and transmit it to the microcontroller chip 20 on the surface of the circuit board 15. The microcontroller chip 20, as the "brain" of the entire system, analyzes and processes the electrical signal. When it is confirmed that the gas concentration exceeds the standard, the microcontroller chip 20 will issue a command to trigger the buzzer 17 located on the side of the gas sensor 16 on the top of the circuit board 15 to sound an alarm, so as to remind the user that there is a gas hazard in the surrounding environment and take appropriate measures.

[0044] The buzzer 17 emits sound in the following ways: slow sound = mild alarm, fast sound = moderate alarm, long sound = severe alarm; at the same time, the microcontroller chip 20 controls the leakage protection module 18 to cut off the power to the gas stove or gas water heater.

[0045] In addition, if leakage occurs in the circuit during power supply, the leakage protection module 18 on the surface of the circuit board 15 located on the side of the gas sensor 16 and the buzzer 17 will quickly detect the abnormal change in current. The leakage protection module 18 will immediately activate the power cut-off function to prevent leakage from causing electric shock accidents or electrical fires and other dangerous situations, thus ensuring the personal safety of users and the safety of electrical equipment.

[0046] To ensure stable performance of the circuit board 15 during long-term operation, the fan 19 connected to the surface of the circuit board 15 and the heat dissipation holes 3 on the surface of the detection box 1 work together. When the fan 19 is running, the side hole on the side of the detection box 1 allows outside air to enter (not shown in the figure), accelerating airflow and dissipating the heat generated by the circuit board 15 through the heat dissipation holes 3 to the outside of the detection box 1, reducing the temperature of the circuit board 15 and preventing damage or performance degradation of electronic components due to overheating. In addition, the indicator light 4 on the surface of the circuit board 15 is used to display the working status of the device. For example, the indicator light 4 may be green when working normally and red when a fault or abnormality occurs, allowing users to intuitively understand the operation of the plug wire. The reset switch 2 cuts off the power after an abnormality occurs in the circuit. When the fault is cleared, the user can press the reset switch 2 to restore the circuit to normal working state. The through hole A21 on the surface of the circuit board 15 is aligned with the through hole B13 inside the detection box 1, possibly for mounting the circuit board 15 and the detection box 1 with bolts.
