Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic structural diagram of an experimental gas release control device according to an embodiment of the present invention, which is applicable to a scenario of gas release control in a related experiment of gas olfaction stimulation.
As shown in fig. 1, the experimental gas release control device includes the following structure:
a test solvent stirrer 110 and a gas flow measurer 120.
Wherein, experiment solvent agitator is used for holding experiment solvent and stirs experiment solvent. Specifically, the test solvent is a solvent prepared in advance, and can volatilize the target test gas. Of course, different concentrations of test solvent will affect the rate at which the test gas can be emitted, but this is still an uncontrollable parameter. In this embodiment, the release of the test gas can be accelerated by the test solvent stirrer by stirring the test solvent.
Further, the flow rate of the test gas released can be measured by the gas flow measuring device 120, so as to achieve the measurability of the flow rate and the flow rate of the test gas. The gas inlet of the gas flow rate measuring device 120 is connected to the gas outlet of the experimental solvent stirrer, and is used for measuring the gas flow rate of the experimental gas released by the experimental solvent after stirring. The main feature of the gas flow rate measuring device 120 is that it is not affected by temperature and pressure variations, and its display interface can directly display flow rate data reading, directly indicate the mass flow rate of the gas, and record the amount of the gas flowing through the installation pipeline.
Further, the experimental solvent stirrer 110 may be controlled to stir the experimental solvent with different stirring intensities, so as to change the flow rate of the experimental gas per unit time. That is to say, different stirring speeds and different volatilization release speeds of the experimental gas can be adjusted according to the flow value displayed by the gas flow measurer 120, so as to achieve the effect of controllable experimental gas flow.
Further, the gas release control apparatus for experiment further includes an air suction pipe for connecting with the gas outlet of the experiment solvent stirrer 110 to deliver the experiment gas to the target experiment object. That is, when the experiment gas discharge flow rate is stable after the experiment solvent stirrer 110 is adjusted, the gas suction pipe may be directly connected to the gas outlet of the experiment solvent stirrer 110, and the experiment gas may be delivered to the target experiment object for the experiment. Then, the flow rate of the experimental gas delivered to the target object is known, and the amount of the experimental gas as a whole can be controlled.
In another alternative embodiment, an air suction pipe for connecting with the air outlet of the air flow rate measurer 120 delivers the experimental air to the target experimental object. That is, the test solvent stirrer 110, the gas flow rate measuring unit 120, and the gas suction pipe are connected in sequence, so that the flow rate of the test gas can be observed in real time during the process of transferring the test gas to the target test object, thereby adjusting the stirring speed of the test solvent stirrer 110 according to the flow rate of the gas.
In a preferred embodiment, the experimental solvent stirrer 110 is an ultrasonic shaker. The ultrasonic oscillator utilizes the high-frequency sound wave of ultrasonic wave to generate oscillation, can stir solution, and the frequency of ultrasonic wave can be adjusted to can adjust the speed that experimental gas released. The experimental solvent is vibrated and stirred by adopting different ultrasonic frequencies, so that the flow of the experimental gas in unit time is changed.
In one specific embodiment, an integrated device for experimental olfactory stimulus release and inhalation may be as shown in fig. 2. In fig. 2, an ultrasonic oscillator, a gas flow rate measuring device, and a nasal inhalation tube are included. Wherein, gas flow caliber is provided with the flow display screen, and the experimenter can be in real time watch the gas flow who surveys. After the gas flow is measured and adjusted, when the gas flow released from the ultrasonic oscillator meets the experimental requirements, the nasal obstruction type air suction pipe can be directly connected with the ultrasonic oscillator to convey the experimental gas to a target experimental object. Wherein, the nose plug type air suction pipe is also provided with a skidding air regulating valve for opening or closing the air pipeline or regulating the flow rate of air. Of course, the air inlet of the gas flow measurer can be connected with the air outlet of the ultrasonic oscillator, the air outlet of the gas flow measurer is connected with the air inlet of the nasal obstruction type air suction pipe, and the experimental gas flow rate in the experimental process is monitored in real time. The experimental gas can be prepared into the experimental solvent with the preset concentration through the solvent preparation test tube, and then the experimental solvent is poured into the solution placing space of the ultrasonic oscillator.
According to the technical scheme of the embodiment, the experimental gas release control device is composed of an experimental solvent stirrer and a gas flow measurer; wherein the experimental solvent stirrer is used for containing and stirring the experimental solvent; the gas inlet of the gas flow measurer is connected with the gas outlet of the experimental solvent stirrer and is used for measuring the gas flow of the experimental gas released by the experimental solvent after stirring.
