This application discloses a friction-rolling self-generating
thermometer, comprising: a housing, a temperature sensor at one end of the housing, an end cap embedded at the other end of the housing, a roller rotatably mounted at the
tail end of the end cap, the roller being rotatable relative to the end cap, a circuit board and an
energy storage component electrically connected to the circuit board inside the housing, a generator connected to the circuit board, a speed regulating gearbox connected to the power input end of the generator, a
drive shaft extending from the speed regulating gearbox, the
drive shaft being connected to the roller, the roller driving the speed regulating gearbox to rotate through the
drive shaft, and the generator being electrically connected to the
energy storage component; the temperature sensor being electrically connected to the circuit board; by using the above method, through the cooperation of the roller, speed regulating gearbox, generator and
energy storage component, it is possible to achieve on-demand charging, unaffected by environmental conditions, and without batteries, making it
safer, eliminating the need for frequent battery replacements, avoiding the worry of running out of power when urgently needed, and also being more
environmentally friendly, with a reasonable and compact structural design, and simple and convenient to use.
