[0001] This utility model relates to the field of power adapter technology, specifically a power adapter with temperature detection function. Background Technology
[0002] A power adapter is a power conversion device for small portable electronic devices and appliances. It is generally composed of components such as a casing, transformer, inductor, capacitor, control IC, and PCB board. Its working principle is to convert AC input to DC output. According to the connection method, it can be divided into wall plug type and desktop type. It is widely used in security cameras, set-top boxes, routers, light strips, massagers and other devices.
[0003] However, existing power adapters have the following drawbacks: when the power adapter is working, the circuit board inside the power adapter will generate some heat. Due to the low heat dissipation efficiency of the power adapter, the excessive heat will affect the normal operation of the circuit board and may even cause safety accidents. In addition, users cannot know the amount of heat generated by the power adapter in a timely manner. Therefore, the current power adapter needs to be improved. Utility Model Content
[0004] The purpose of this utility model is to provide a power adapter with a temperature detection function to solve the problems mentioned in the background art, such as the internal circuit board of the power adapter on the market generating some heat, the user not being able to know the amount of heat generated by the power adapter in a timely manner, and the low heat dissipation efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a power adapter with temperature detection function, comprising a power adapter body and a circuit board, one end of the power adapter body being connected to a power cord, the other end of the power adapter body being provided with a socket, the circuit board being installed inside the power adapter body, side frames being fixed on both sides of the power adapter body, heat dissipation mechanisms being installed at both ends of the power adapter body near the side frames, and a temperature sensor being installed on the inner wall of the power adapter body near the circuit board, the heat dissipation mechanism comprising a dustproof mesh, heat dissipation holes and a magnetic sheet, and heat dissipation holes being opened on the inner walls at both ends of the power adapter body.
[0006] Preferably, magnetic sheets are provided on the outer walls of both ends of the power adapter body, and a dustproof mesh is magnetically connected to one side of the magnetic sheets.
[0007] Preferably, a display screen is mounted on the outside of the power adapter body, and heat-conducting plates are mounted on both ends of the power adapter body near the heat dissipation mechanism.
[0008] Preferably, the heat-conducting plate has heat sinks evenly distributed on the side away from the circuit board, and the power adapter body has a limit mechanism connected to the end near the socket.
[0009] Preferably, the limiting mechanism includes a screw, a fixing block, a limiting plate, and a guide rod, and a fixing block is fixed on the outer wall of one end of the power adapter body.
[0010] Preferably, a screw is threaded into the middle of the fixing block, and the end of the screw near the insertion port is connected to a limiting plate via a bearing.
[0011] Preferably, the limiting plate is connected to guide rods at both ends, and the guide rods slide through both ends of the fixing block.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. Equipped with a temperature sensor, display screen, and heat dissipation mechanism, the temperature sensor detects the heat generated by the circuit board and displays the detected heat value on the screen, allowing users to easily view and take cooling measures. Simultaneously, heat is absorbed by the heat-conducting plate and dissipated through the heat sink to the heat dissipation holes, where it is then exhausted. A dust filter prevents dust from entering the power adapter body through the heat dissipation holes. By incorporating a temperature sensor, display screen, and heat dissipation mechanism, rapid heat dissipation is achieved during temperature detection, preventing overheating, improving the safety of the power adapter, and extending its service life.
[0014] 2. A limiting mechanism is provided. After the connector plug is inserted into the socket, the screw is rotated to engage with the fixing block. Then the screw pushes the limiting plate to one side, while the guide rod slides inside the fixing block, so that the limiting plate abuts against both sides of the connector plug to prevent the plug from becoming loose and improve the stability of the power adapter.

Detailed Implementation
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a power adapter with temperature detection function, including a power adapter body 1 and a circuit board 4. One end of the power adapter body 1 is connected to a power cord 2, and the other end of the power adapter body 1 is provided with a socket 3. The circuit board 4 is installed inside the power adapter body 1, and side frames 6 are fixed on both sides of the power adapter body 1.
[0024] Please see Figures 1-6 The power adapter body 1 has heat dissipation mechanisms 8 installed at both ends near the side frame 6. A temperature sensor 9 is installed on the inner wall of the power adapter body 1 near the circuit board 4. The heat dissipation mechanism 8 includes a dustproof mesh 801, heat dissipation holes 802, and a magnetic sheet 803. Heat dissipation holes 802 are provided on the inner walls of both ends of the power adapter body 1. Magnetic sheets 803 are provided on the outer walls of both ends of the power adapter body 1. A dustproof mesh 801 is magnetically connected to one side of the magnetic sheet 803. A display screen 7 is installed on the outer side of the power adapter body 1. A heat-conducting plate 11 is installed at both ends of the power adapter body 1 near the heat dissipation mechanism 8. Heat dissipation fins 10 are evenly distributed on the side of the heat-conducting plate 11 away from the circuit board 4. The temperature sensor 9 is a thermistor sensor. The heat-conducting plate 11 and the heat dissipation fins 10 are both made of copper.
[0025] In practical implementation, when the power adapter is working, the circuit board 4 inside the power adapter will generate some heat. Due to the low heat dissipation efficiency of the power adapter, excessive heat can affect the normal operation of the circuit board 4 and may even cause safety accidents. Furthermore, users cannot know the amount of heat generated by the power adapter in a timely manner. The heat generated by the circuit board 4 can be detected by the temperature sensor 9 and the detected heat value can be displayed on the display screen 7, making it convenient for users to check and take cooling measures. At the same time, the heat can be absorbed by the heat conduction plate 11 and dissipated to the heat dissipation hole 802 through the heat sink 10. Then, the heat is discharged from the heat dissipation hole 802. The dustproof net 801 can prevent dust from entering the power adapter body 1 from the heat dissipation hole 802. By setting the temperature sensor 9, the display screen 7 and the heat dissipation mechanism 8, heat dissipation can be carried out quickly during the temperature detection process, preventing excessive heat, improving the safety of the power adapter and extending its service life.
[0026] See also Figures 1-4 The power adapter body 1 is connected to a limiting mechanism 5 at one end near the socket 3. The limiting mechanism 5 includes a screw 501, a fixing block 502, a limiting plate 503, and a guide rod 504. A fixing block 502 is fixed on the outer wall of one end of the power adapter body 1. The screw 501 is threaded into the middle of the fixing block 502. The end of the screw 501 near the socket 3 is connected to the limiting plate 503 through a bearing. The two ends of the limiting plate 503 are connected to the guide rods 504, and the guide rods 504 slide through the two ends of the fixing block 502. The limiting plate 503 is U-shaped.
[0027] In practice, since one end of the power adapter is inserted into the connector plug, but the plug is prone to loosening, affecting the working stability of the power adapter, the screw 501 can be rotated after inserting the connector plug into the socket 3 to engage with the fixing block 502. Then, the screw 501 pushes the limiting plate 503 to one side, while the guide rod 504 slides inside the fixing block 502, so that the limiting plate 503 abuts against both sides of the connector plug, preventing the plug from becoming loose and improving the stability of the power adapter.
[0028] Working principle: When using this power adapter with temperature detection function, firstly, insert the connector plug into the socket 3. Then, the position of the plug is restricted by the limiting mechanism 5 to prevent loosening. Then, the power cord 2 is connected to other devices. The circuit board 4 converts the AC voltage of the power supply into the DC voltage and current required by the device. During the operation of the circuit board 4, the temperature is detected and displayed by the temperature sensor 9 and the display screen 7. At the same time, the heat is dissipated by the heat dissipation mechanism 8, which improves the safety of the power adapter and extends its service life. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
