AI Technical Summary

Problems solved by technology

The gas in the bottle of the above-mentioned device cannot be exported and collected, and the smell diffuses when the container bottle is opened, making repeated identification impossible, resulting in inaccurate identification results
Moreover, the above-mentioned device is only suitable for dividing each part into small samples. The container bottle is generally glass with a size of 1L, and the division of the sample will increase its surface area. The odor produced by multiple samples will be different from that produced by the whole part. The simulation process is not accurate
Some auto parts are large in size, up to 1m in length, and irregular in shape, and the above-mentioned device cannot be used. Therefore, it is necessary to provide an odor evaluation device that can accurately simulate large auto parts

Embodiment 2

[0041] The odor evaluation device is the same as in Example 1, and the steps of the method of use are:

[0042] a. The volume to the heating device 1 is 2m 3 Put the parts to be tested in the sample bag 2, use the bead 7 and the pressure groove 8 to clamp and seal the opening 6 of the sample bag 2, keep the air valve 4 open, and connect the end of the heating device 1 outer air pipe 3 to a vacuum pump to vacuum the sample Bag 2 is vacuumed;

[0043] b. Fill 1.6m into the sample bag 2 3 For high-purity air, close the air valve 4;

[0044] c. Turn on the heating device to raise the temperature to 65°C and keep it for 6h;

[0045] d. Turn off the heating device 1, open the air valve 4, connect the end of the air pipe 3 to an air pump, and export the gas to be tested in the sample bag 2 for odor evaluation.

Embodiment 3

[0047] The odor evaluation device is the same as in Example 1, and the steps of the method of use are:

[0048] a. The volume to the heating device 1 is 3m 3 Put the parts to be tested in the sample bag 2, use the bead 7 and the pressure groove 8 to clamp and seal the opening 6 of the sample bag 2, keep the air valve 4 open, and connect the end of the heating device 1 outer air pipe 3 to a vacuum pump to vacuum the sample Bag 2 is vacuumed;

[0049] b. Fill 2.4m into the sample bag 2 3 For high-purity nitrogen, close the gas valve 4;

[0050] c. Turn on the heating device to raise the temperature to 100°C and keep it for 2 hours;

[0051] d. Turn off the heating device 1, open the air valve 4, connect the end of the air pipe 3 to an air pump, and export the gas to be tested in the sample bag 2 for odor evaluation.

Abstract

The invention discloses a smell evaluating device capable of simulating large automobile parts and a use method thereof. The whole volatizing process of the automobile parts in an automobile is simulated, and gas is collected and guided out. The automobile part smell evaluating device is characterized by comprising a heating device and a sample bag located in the heating device, gas pipes penetrating through the heating device are connected to the sample bag, and gas valves are arranged at the portions where the gas pipes are communicated with the sample bag. The automobile part smell evaluating device is simple in structure, convenient to use, capable of being repeatedly used, efficient and economical.

Description

technical field [0001] The invention relates to the air quality of automobiles, in particular to a device for evaluating the odor of automobile parts and a method for using the same. Background technique [0002] The so-called smell is the olfactory perception of the physical properties of volatile substances by the human olfactory organ using air as the medium. The smell in the car is the small molecules volatilized by various parts in the car, which diffuse in the air in the car and are then perceived by people's olfactory organs. If the smell in the car is not good, it will seriously affect the subjective feelings of the driver and passengers, and ultimately affect the choice of the driver and passengers for this brand of car. Therefore, it is necessary to detect the smell of auto parts in advance. How to accurately and effectively simulate the volatilization process of auto parts in the car, and then detect the smell is a difficult problem in the current car air quality...
