Description

Technical Field

[0001] This utility model belongs to the field of odor detection technology. Specifically, this utility model relates to an odor evaluation device for automotive parts. Background Technology

[0002] As a common means of transportation, the smell inside cars is receiving increasing attention from consumers. The air quality inside cars is valued by both OEMs and consumers and is a key consideration when purchasing a car. The main components affecting the air quality and smell inside a car are interior parts and sealing strips. The chemical substances emitted by these parts are often the source of the odor, allowing consumers to smell the odor inside the car.

[0003] A patent application (patent number 201721455190.1, published on June 1, 2018) discloses a blind odor testing device for materials, comprising a sealed container, an inflation device, a test bag, and an odor evaluation bag. The inflation device, connected to the sealed container via a gas tube, is used to inflate the sealed container with gas to create positive pressure. The test bag contains the test sample and is placed within the sealed container. The odor evaluation bag collects the volatile odor emitted by the test sample; the test bag and the odor evaluation bag are connected via a gas supply tube. Before the odor evaluation begins, the test bag is placed in the container that creates positive pressure. When the test bag is subjected to positive pressure in the container, the gas containing volatile organic compounds is forced into the connected vacuum odor evaluation bag, thus capturing the volatile substances emitted by the sample. This device allows for the isolation of evaluators from the actual sample, evaluating only the gaseous products emitted by the sample, achieving blind evaluation of the sample, and ensuring an objective and impartial odor assessment.

[0004] Odor evaluation relies on the sense of smell of professional odor personnel. In ordinary odor evaluation, personnel can usually see or touch the components before conducting the evaluation. This can lead to the odor evaluator being influenced by the components and subconsciously giving results, thus compromising the accuracy of the evaluation. Because personnel can directly see or touch the samples, the objectivity of the odor evaluation results is challenged and questioned.

[0005] In the aforementioned prior art, the blind evaluation device can only take one bag of sample at a time. Odor evaluators evaluate at different time periods. Due to the influence of sample temperature and previous evaluators' descriptions of the odor, the results of subsequent evaluators may be guided by the previous results, causing the odor results to deviate from the truth. Utility Model Content

[0006] The present invention aims to provide an odor evaluation device for automotive parts that can improve the accuracy and fairness of odor detection.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an odor evaluation device for automotive parts, comprising an oven and an air guiding device, wherein a sample bag is provided inside the oven, the sample bag contains the parts to be tested, and the sample bag is connected to an odor bag through the air guiding device.

[0008] The gas guiding device consists of an inflation pump and a suction pump. The sample bag is equipped with two air tubes, which are connected to the suction pump and the inflation pump, respectively.

[0009] The air pump is connected to the odor bag via an air pipe.

[0010] There are at least two scent bags.

[0011] The air pump is connected to a gas tank via an air pipe.

[0012] The air pipe is equipped with an air valve.

[0013] The oven is equipped with a support at the bottom.

[0014] The technical advantages of this invention are as follows: the odor evaluation device of this invention can ensure that different evaluators conduct odor evaluations at similar temperatures, and will not result in inaccurate odor results due to the influence of gas temperature or the guidance of evaluators, making the results more reliable, credible, objective and fair. In addition, it can fill multiple odor bags for evaluation by multiple different evaluators, which helps to improve the fairness and accuracy of the test. Attached Figure Description

[0015] This manual includes the following figures, which illustrate the following:

[0016] Figure 1 This is a schematic diagram of the structure of an odor evaluation device for automotive parts according to the present invention.

[0017] The following are labeled in the diagram: 1. Oven; 2. Sample bag; 3. Component to be tested; 4. Support; 5. Ventilation valve; 6. Gas pipe; 7. Inflation pump; 8. Gas tank; 9. Vacuum pump; 10. Odor bag. Detailed Implementation

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0019] Please see Figure 1An odor evaluation device for automotive parts includes an oven 1 and an air guiding device. The oven 1 contains a sample bag 2, which holds a component 3 to be tested. The sample bag 2 is connected to an odor bag 10 via the air guiding device. The air guiding device introduces air from the sample bag 2 containing the component 3 into the odor bag 10. Multiple odor bags 10 can be filled, allowing multiple testers to detect the odor. This improves measurement accuracy by using data from multiple testers, while also ensuring fairness of the test results by separating the testers.

[0020] The gas guiding device is divided into an inflation pump 7 and an exhaust pump 9. The sample bag 2 is equipped with two air tubes 6, which are connected to the exhaust pump 9 and the inflation pump 7 respectively. Through the inflation pump 7 and the exhaust pump 9, the sample bag 2 can be inflated or deflated, which can quickly fill the odor bag 10 and replenish the gas in the sample bag 2.

[0021] The air pump 9 is connected to the odor bag 10 through the air tube 6; the air pump 9 extracts the gas from the sample bag 2 and sends it into the odor bag 10 for easy testing.

[0022] There are at least two odor bags 10; this ensures that at least two measurers are involved in the testing, effectively improving the accuracy and fairness of the measurement.

[0023] An air pump 7 is connected to a gas tank 8 via an air pipe 6. The air pump 7 fills the sample bag 2 with air from the gas tank 8, and the sample bag 2 is heated by an oven 1 so that the odor of the component 3 to be tested can fill the sample bag 2. The air pump 9 can then extract the air from the sample bag 2 and send it into an odor bag 10. This process can be repeated to fill multiple odor bags 10, which can be used for evaluation and testing by multiple different evaluators, thus improving the fairness and accuracy of the test.

[0024] The trachea 6 is equipped with a ventilation valve 5; the ventilation valve 5 is used to control the opening and closing of the trachea 6.

[0025] The bottom of the oven 1 is equipped with a support 4 to support the oven 1.

[0026] The technical effects of this utility model are as follows: the odor evaluation device of this utility model can ensure that different evaluators conduct odor evaluations at similar temperatures, and the odor results will not be inaccurate due to the influence of gas temperature and the guidance of the evaluators, making the results more reliable, credible, objective and fair. In addition, multiple odor bags 10 can be filled for evaluation by multiple different evaluators, which helps to improve the fairness and accuracy of the test.
