Description

Technical Field

[0001] The utility model belongs to the technical field of odor detection, and in particular relates to a device that can replace sensory organs to detect the odor value of a sample. Background Art

[0002] Odors primarily originate from a series of irritating and toxic gases released by microbial fermentation of organic matter at high temperatures. These gases, primarily ammonia (NH3) and hydrogen sulfide (H2S), can be extremely harmful if inhaled. Therefore, it's often necessary to test the odor levels of certain items, using odor detection equipment.

[0003] In the prior art, the utility model patent with patent number CN202220245820.7 discloses an odor content detection device that is installed in a gas pipeline. The device includes a housing, a controller, an odor detection component, and an alarm component. The housing has a storage space inside and is provided with an air inlet pipe and an air outlet pipe. Natural gas in the gas pipeline can enter the interior of the device through the air inlet pipe, and natural gas in the gas pipeline can enter the gas pipeline through the air outlet pipe, thus forming a closed loop. The controller is located in the internal space of the housing, and the odor detection component is located in the internal space of the housing. The odor detection component is electrically connected to the controller and can detect the concentration of odor in the natural gas. The alarm component is located on the side of the housing and is electrically connected to the controller. When the odor concentration is too low or too high, the alarm component will sound an alarm, reminding the staff to increase or decrease the odor concentration.

[0004] The odor content detection device provided by the aforementioned patent is primarily used for odor detection in natural gas pipelines. When testing the odor values ​​of samples of some substances in daily life, workers often use sensory methods and an odor detector to detect them. The main method of sensory detection is smell, but inhaling too much odor can cause physical discomfort to workers. Furthermore, detecting the odor value of a sample through sensory methods cannot guarantee that the odor of the sample is confined to a certain spatial range. If the odor of the substance sample quickly diffuses into the air, the odor value of the sample cannot be effectively sensed and detected. Therefore, existing odor detection methods are not suitable for detecting the odor value of substance samples, and are prone to inaccurate detection results due to the rapid diffusion of the odor of the substance sample. Utility Model Content

[0005] The purpose of the utility model is to provide a device that can replace the sensory detection of the odor value of a sample, so as to solve the problem that the existing odor detection method is not suitable for detecting the odor value of a material sample and the detection result is not accurate due to the rapid diffusion of the odor of the material sample.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The utility model limits the space around the sample by fixing the cup cover to ensure that the odor of the sample will not spread quickly. At the same time, the movable cup cover and the fan can make the odor emitted by the sample spread quickly and evenly into the space of the fixed cup cover.

[0021] 4. This utility model can replace the sensory method to detect the odor value of the sample. It is harmless to the human body and the detection value is relatively accurate. The traditional sensory method of detecting odor value will cause certain discomfort to the tester's body and the test results are obviously subjective.

[0022] 5. This utility model can detect the odor value of quantitative samples and quantitatively compare the differences between samples, providing a more scientific and accurate basis for the experiment;

[0023] 6. The utility model can expand the selection of different gas detectors to detect different gas concentrations as needed, rather than being limited to detecting odor concentrations. For example, to detect odor, you can choose an odor detector with the function of detecting NH3 and H2S concentrations. To detect other toxic and harmful gases (carbon monoxide, formaldehyde, etc.), you can choose a gas detector with this function. BRIEF DESCRIPTION OF THE DRAWINGS
