Digital smell recognition capability detection device

Abstract

The invention discloses a digital olfactory recognition capability detection device, which comprises a vortex ring shell and a vortex ring nozzle, and is characterized in that the vortex ring shell is provided with at least two cavities for generating vortex rings and a connecting rod driving mechanism for generating linkage of the cavities; the linkage of the cavities is controlled by the connecting rod driving mechanism, so that the volume of jet gas of the vortex ring nozzle is adjusted. The jet flow volume can be finely adjusted, heating caused by long-time energization is avoided, vibration is small, noise is low, and meanwhile the vortex ring can be periodically excited for a long time at high frequency.

Description

technical field [0001] The invention relates to the technical field of odor transmission, in particular to a digital olfactory recognition ability detection device. Background technique [0002] It is generally believed that olfactory function has little effect on human health, so olfactory health care is often ignored, even if the sense of smell is lost, it is not taken seriously. Osmia not only affects our quality of life, but even threatens life safety. Because we can't smell it, we can't notice gas leaks, and we can accidentally eat spoiled food. Studies have shown that stable olfactory impairment is often not an independent pathology, and may be an early symptom of intracranial lesions or mental illnesses in addition to unexpected factors such as external force impacts. If it is not treated in time, it will lead to the onset of its symptoms, which will have serious consequences such as irreversible brain damage. [0003] In the prior art, the olfactory detection is m...

Problems solved by technology

[0004] 1. The iron core is prone to heat and cannot be energized for a long time;

[0005] 2. When the electromagnet is energized and pushed, there will be a large vibration;

[0006] 3. When an electromagnet with an iron core is used, the electromagnet is prone to noise;

[0007] 4. The iron core will rub against the support of the coil when it is excited;

[0008] 5. Electromagnetic emission cannot excite the vortex ring periodically for a long time and high frequency
