Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-2As shown, this utility model provides a friction-rolling self-generating thermometer, characterized in that it includes: a housing 3, one end of which is provided with a temperature sensor 2, and the other end of which is embedded with an end cap 11. A roller 12 is rotatably mounted on the tail end of the end cap 11, and the roller 12 can rotate relative to the end cap 11. The housing 3 also contains a circuit board 4 and an energy storage component 16 electrically connected to the circuit board 4. The energy storage component 16 is also connected to a generator 15. The output end of the generator 15 is connected to a speed regulating gearbox 19. The speed regulating gearbox 19 also extends a drive shaft 20, which is connected to the roller 12. The roller 12 drives the generator 15 to rotate and generate electrical energy after being adjusted by the speed regulating gearbox 19 via the drive shaft 20. The generator 15 is electrically connected to the energy storage component 16. The temperature sensor 2 is electrically connected to the circuit board 4.

[0022] Specifically, the housing 3 has one large end and one small end. A temperature sensor 2 is housed inside the smaller end, and a metal sleeve 1 is fitted over the end containing the temperature sensor 2 to improve heat conduction efficiency and provide protection. A circuit board 4 is housed inside the larger end of the housing 3. The temperature sensor 2 is electrically connected to the circuit board 4. A display screen 6 is mounted on the circuit board 4, and a plastic frame 7 is provided around the display screen 6. A switch 8 and a button 9 are located on the switch 8 at one end of the circuit board 4. A display window 21 is provided at the position corresponding to the display screen 6 on the housing 3, and a transparent film 5 is provided on the display window 21 to protect the display screen 6. Pressing the button 9 turns the switch 8 on / off, and the circuit board 4 converts the detected value from the temperature sensor 2 into a digital signal, which is then displayed on the display screen 6. To provide power for the operation of the circuit board 4, an energy storage component 16, a generator 15, and a speed regulating gearbox 19 are also housed inside the housing 3. The energy storage component 16 is electrically connected to the circuit board 4, and the speed regulating gearbox 19 is connected to the generator... The drive shaft 20 of generator 15 is connected to the generator 15. An end cover 11 is embedded at one end of the housing 3, and a roller 12 is rotatably mounted on the end cover 11. The drive shaft 20 of the speed regulating gearbox 19 is connected to the roller 12. The kinetic energy of the roller 12 during rotation is converted into a corresponding speed and torque by the speed regulating gearbox 19 and transmitted to the drive shaft 20 of generator 15, causing generator 15 to rotate and generate electrical energy. This electrical energy is then stored in the energy storage component 16 and can be output when needed. The energy storage component 16 includes energy storage elements and its charging and discharging management circuit. Its function is to efficiently and continuously lock and control the electrical energy generated by generator 15 for use by the circuit board. The circuit board also has an MCU and its associated circuitry. Operating on the electrical energy provided by the energy storage component, it detects and processes information from the temperature sensor and the energy storage component, driving the display screen to show the user temperature and energy storage information. Both the energy storage component and the circuit board utilize mature existing technologies, so their specific structures will not be described in detail here.

[0023] To fix the roller 12 to the end cover 11 and connect it to the drive shaft 20 of the speed regulating gearbox 19, a retaining piece 13 is provided inside the end cover 11. The retaining piece 13 is fixedly connected to the roller 12 by screws 14. The roller 12 cannot be detached from the end cover 11 due to the restriction between the retaining piece 13 and the end cover 11. A round hole is provided in the middle of the retaining piece 13, and the drive shaft 20 passes through the round hole to connect with the roller 12. The roller 12 is provided with a groove, and the end of the drive shaft 20 is inserted into the groove to connect with the roller 12. When the roller 12 rotates, it drives the drive shaft 20 to rotate.

[0024] Furthermore, to facilitate fixing the circuit board 4 and the generator 15 inside the housing 3, an inner lower cover 18 and an inner upper cover 10 are also provided inside the housing 3. For ease of description, one end of the inner lower cover 18 is defined as the first end and the other end as the second end. The inner upper cover 10 is fastened to the second end of the inner lower cover 18 and covers the area of ​​the second end. The circuit board 4 and the energy storage component 16 are fixedly installed in the first end, while the generator 15 and the speed regulating gearbox 19 are located in the second end. When the inner lower cover 18 is placed inside the housing 3, it is fixed inside the housing 3 by the compression of the end cover 11. To facilitate the user's awareness that the reading time of the temperature sensor 2 has been reached, the circuit board 4 is also connected to a buzzer 17. The buzzer 17 emits a buzzing sound to remind the user that the detection has been completed after the temperature value of the temperature sensor 2 has been fixed for a predetermined time.

[0025] To prevent moisture from entering through the gap between the roller 12 and the end cap 11 during use, a sealing ring is provided between the roller 12 and the end cap 11 to block moisture from entering the housing 3.

[0026] Furthermore, to increase the friction of the roller 12, an anti-slip texture or a soft rubber layer with an anti-slip texture is provided on the outer surface of the roller 12. The anti-slip texture improves the rotational efficiency of friction.

[0027] When in use, the housing 3 can be held with one hand, and the roller 12 can be rubbed by the body or external conditions such as a table to make the roller 12 rotate. The roller 12 drives the transmission shaft 20 to rotate through the locking piece 13. The transmission shaft 20 changes the transmission ratio through the speed regulating gearbox 19 and causes the generator 15 to rotate, generating electrical energy. The electrical energy is stored in the energy storage component 16. When needed, the circuit of the circuit board 4 can be connected by pressing the button 9, the energy storage component 16 outputs electrical energy, and the entire circuit starts to work.

[0028] It should be noted that the metal sleeve 1 part can also be replaced with a long metal probe, and the temperature sensor is placed inside the long metal probe. In this case, the temperature of the food can be measured through the long metal probe.

[0029] In summary, through the cooperation of rollers, speed-regulating gearbox, generator and energy storage components, it is possible to recharge at any time, unaffected by environmental conditions, without the need for frequent battery replacements, making it more environmentally friendly. The structure is reasonable and compact, and it is simple and convenient to use.

[0030] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
