Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation technology, specifically relating to a power-type thermistor device with high heat dissipation efficiency. Background Technology

[0002] Previously, temperature was measured mostly using alcohol or mercury thermometers, as well as some mechanical switches. These things were either fragile, slow to react, and not very accurate. With thermistors, the situation is different. Thermistors are electronic components that are particularly sensitive to temperature. When the temperature changes, their resistance changes significantly. They are very convenient to use, whether measuring human body temperature, equipment temperature, or ambient temperature. Therefore, they are now used in many places to measure temperature.

[0003] Traditional charger plugs always have some concerns. They often get hot during charging, especially after charging phones and tablets for extended periods. The plug and cable connections become noticeably hot, especially in summer, raising safety concerns. Overheating also slows down charging; what should take an hour to fully charge might take ten minutes longer. Prolonged high temperatures accelerate the aging of internal components, potentially leading to poor contact and even replacement. Many chargers, in their compact design, have very little space for heat dissipation, which not only shortens their own lifespan but can also potentially affect nearby devices. Summary of the Invention

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0018] Reference Figure 1-4 This embodiment of the present invention provides a high-heat-dissipation-efficiency power-type thermistor device, comprising: The plug assembly 100 includes a housing 101, an air inlet 102 formed on the side wall of the housing 101, an air outlet 103 formed on the side wall of the housing 101, a base plate 106 snapped onto the bottom of the housing 101, a pin 104 inserted into the side wall of the base plate 106, and a slot 105 formed on the top of the housing 101. The heat dissipation assembly 200 includes a heat sink 201 disposed inside the housing 101, a circuit board 202 movably connected to the side wall of the heat sink 201, a thermistor 203 mounted on the side wall of the circuit board 202, and a servo motor 204 adapted to be mounted on the side wall of the housing 101. The output end of the servo motor 204 is fixedly connected to a fan blade 205. Specifically, the outer casing 101 has air inlets 102 and air outlets 103 on both sides, the top pin 104 is connected to the power supply, the top slot 105 is used to supply power to the USB interface 206, the bottom plate 106 encloses the overall structure, the heat sink 201 has a multi-layer heat dissipation structure as the core, which is used to dissipate the heat from the circuit board 202. When the thermistor 203 detects that the temperature is too high, it starts the servo motor 204, and the fan blades 205 rotate to cool the inside.

[0019] The heat dissipation assembly 200 also includes a USB interface 206 fixedly connected to the side wall of the circuit board 202, the USB interface 206 being attached to the side wall of the heat sink 201, and the USB interface 206 being attached to the side wall of the slot 105.

[0020] Furthermore, one end of the USB interface 206 is connected to the circuit board 202, and the other end is inserted into the slot 105. At the same time, the side wall of the USB interface 206 is attached to the heat sink 201 to enjoy the heat dissipation effect.

[0021] The heat dissipation assembly 200 also includes a wire 208 fixedly connected to the side wall of the circuit board 202, and the wire 208 is snapped into the inner wall of the connector 207.

[0022] Preferably, the pin 104 is snapped into the bottom of the connector 207, and the wire 208 is snapped into the side wall of the connector 207. The wire 208 is also connected to the circuit board 202, so that electrical energy can be conducted from the pin 104 into the circuit board 202.

[0023] The circuit board 202 is fixedly connected to the inner wall of the housing 101, and thermal grease is applied between the circuit board 202 and the heat sink 201.

[0024] It should be noted that the heat generated by the circuit board 202 is transferred to the heat sink 201 through the thermal grease, and then the heat sink 201 dissipates it, making the heat transfer efficiency higher.

[0025] When in use, the plug 104 is inserted into the socket, and the USB interface 206 is connected to the charging device via the data cable. During the charging process, the thermistor 203 detects that the circuit board 202 is too hot and starts the servo motor 204. The fan blades 205 at the output end rotate and generate wind that blows through the gaps in the heat sink 201, carrying away the heat generated by the circuit board 202.

[0026] In summary, the design of the heat sink 201, servo motor 204, and fan blades 205 ensures rapid heat dissipation during charging, making it safe to use even in summer. The thermistor 203 prevents additional power consumption when not generating heat, eliminating concerns about power outages or safety hazards. Improved heat dissipation also leads to more stable charging efficiency, maintaining the initial charging speed steadily, allowing phones and tablets to fully charge quickly. Furthermore, the low temperature environment slows down the aging of internal components, significantly increasing the durability of the plug and reducing the need for frequent replacements. While ensuring efficient heat dissipation, portability is not compromised; its size is similar to a standard plug, taking up minimal space when plugged into a socket and not interfering with nearby devices.
