Description

Technical Field

[0001] The invention relates to the field of bite force detection, and in particular to a bite force measuring device. Background Art

[0002] In order to determine the oral health of animals, it is necessary to detect the bite conditions of animals. Since dogs and other animals are active and cannot communicate, it is difficult to measure their actual bite force, so the theoretical limit of their bite force is usually calculated by simulation. However, the simulation method has a weak basis, and the numerical error of the animal's bite force is very large, making it difficult to accurately determine the oral health of the animal. In addition, there are problems such as inaccurate control of the bite position during the measurement process, low accuracy of the measurement data, and large data deviation. The willingness of the animal to cooperate during the measurement process is also an important factor affecting the bite force measurement.

[0003] Of course, there are bite force measurement devices that use sensors. The bite force of animals is measured by letting the animals bite the position of the sensors in the measurement device. However, the sensors are easily damaged by direct bites of animals and can usually only be used once, which is too expensive. Summary of the invention

[0008] A gap is provided between the base material portion and the force-bearing portion. When the sensing head is bitten by an animal, the free end of the force-bearing portion deviates toward the base material portion to apply pressure to the pressure sensor.

[0009] In a preferred embodiment, a surface of the force-bearing portion adjacent to the outer circumferential surface of the sensing body matches the outer circumferential surface of the sensing body.

[0010] In a preferred embodiment, the substrate portion and the force-bearing portion are both hard sheet members, and the hard sheet members are equally divided along the outer circumference of the sensing body.
