Olfaction detector capable of setting odor concentration

Abstract

The invention provides an olfaction detector capable of setting odor concentration. The olfaction detector comprises a box body and a first partition plate arranged in the box body, the interior of the box body is divided into a first cavity and a second cavity by the first partition plate, an air outlet is formed in the side wall of the second cavity, a nasal mask is arranged on the outer side ofthe air outlet, and a first plugging structure is arranged on the inner side of the air outlet; a vertically-arranged second partition plate is arranged at the bottom of the second cavity, a third cavity is formed by the second partition plate and the side wall of the box body, and a second plugging structure is arranged at the top of the third cavity; an electric heating plate and a metering valve are arranged in the third chamber, and the metering valve drips liquid medicine towards the electric heating plate; an air extracting pump is arranged in the first cavity, the air inlet end of theair extracting pump communicates with the second cavity through a first air pipe, and the air inlet end of the air extracting pump communicates with the third cavity through a second air pipe; and a gas concentration sensor is arranged on the side wall of the second cavity. The odor concentration can be detected in real time, the odor concentration can be conveniently set before detection, and therefore detection of odor of different concentrations can be performed on patients conveniently.

Description

technical field [0001] The invention relates to the field of olfactory detection equipment, and more specifically, relates to an olfactory detection instrument capable of setting odor concentration. Background technique [0002] Medical testing equipment refers to the real-time or non-real-time qualitative testing and measurement of people in the fields of production, experiment, scientific research, use, maintenance, etc. A process for testing reports. In the process of using medical equipment, we need to continuously detect and evaluate to ensure its normal work, so that medical equipment can give full play to its advantages. Therefore, daily monitoring of medical equipment is essential. [0003] Medical detection equipment includes olfactory detection equipment. Most of the existing general olfactory detection equipment only detects the sense of smell through the odor distribution box, the detection effect is limited, and the odor concentration cannot be better adjusted,...
