Description

Technical Field

[0001] This utility model relates to the field of olfactometer technology, and more specifically, to a multifunctional ODP olfactometer. Background Technology

[0002] The ODP olfactometer is a professional instrument for detecting odor substances. In the tobacco industry, it is commonly used to detect the aroma of flavorings and fragrances.

[0003] The olfactory port of the ODP olfactometer, also known as the detection port, is a functional component that guides odors to the detection port for the testing personnel to smell the odors by nasal inhalation. It is usually used for two purposes: one is to allow the testing personnel to smell directly, and the other is to connect to accessories such as collection bags to enrich the odors. When switching functions, the olfactory port needs to be disassembled and replaced, which is relatively cumbersome.

[0004] ODP olfactometers are purchased equipment, and their structure is relatively fixed and precise. The above-mentioned usage methods are also relatively niche, making it difficult to provide more functional gas paths by modifying the internal gas path channels to meet the needs of using both functions simultaneously.

[0005] Based on the above situation, it is necessary to improve the ODP olfaction port to enable it to perform both olfaction and enrichment functions.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a multifunctional ODP olfaction port that combines olfaction and enrichment functions.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a multifunctional ODP olfaction port, including an air intake channel, a relay buffer chamber, an olfaction channel, and an enrichment channel; The air intake channel is connected to the relay buffer chamber through a one-way air blowing valve, which is used to introduce the gas to be tested into the relay buffer chamber. A first bidirectional blowing valve is provided at the outlet of the relay buffer chamber connected to the olfaction channel, which is used to introduce the gas to be tested into the olfaction channel or to block the gas from entering the olfaction channel. A second bidirectional air-blowing valve is installed at the outlet of the relay buffer chamber connected to the enrichment channel, which is used to introduce the gas to be tested into the enrichment channel or to block it from entering the enrichment channel.

[0009] This invention can effectively integrate olfaction and enrichment functions to meet different needs.

[0010] Based on the above, a snoring mask is detachably installed at the end of the snoring channel. The snoring mask is detachable, facilitating cleaning, replacement, and maintenance.

[0011] Based on the above, an enrichment cavity is detachably installed at the end of the enrichment channel. This detachable structure makes it more convenient to use.

[0012] Based on the above, the enrichment cavity is an adsorption tube, an absorption belt, a collection bag, or a collection bottle. These collection facilities are all relatively conventional enrichment equipment.

[0013] Based on the above, the one-way air blowing valve is an annular valve, comprising an annular valve body and air outlets evenly distributed on one side end face of the annular valve body. An air passage is provided within the annular valve body to connect each air outlet, and an air inlet is provided on the side of the annular valve body. The orientation of the air outlets is the same as the flow direction of the air inlet passage. This annular valve can result in a more even dispersion of the discharged airflow.

[0014] Based on the above, the air inlet of the one-way air valve is connected to an air source via an air inlet line. The air source is either an inert gas or air to ensure a stable supply of air.

[0015] Based on the above, the bidirectional air-blowing valve is an annular valve, comprising an annular valve body and two sets of air outlets evenly spaced on both end faces of the annular valve body. The annular valve body has two air passages that respectively connect to the two sets of air outlets. An air inlet is located on the side of the annular valve body, and a movable switch is provided at the air inlet for selectively opening one of the two air passages. Compared to a unidirectional air-blowing valve, it can blow air to both sides, ensuring the switching action and uniform distribution of the airflow.

[0016] Based on the above, an arc-shaped cavity is provided at the air inlet of the annular valve body. The movable switch is an arc-shaped slider that slides radially with the arc-shaped cavity. Air ports are provided on both ends of the arc-shaped cavity corresponding to two air passages. The arc-shaped slider selectively blocks one of the air ports by sliding. This structure optimizes the switching mechanism of the annular valve body, making its structure simpler. Since this structure is specifically designed for this system, there is no need to consider its universality in other fields.

[0017] Based on the above, the air inlet of the bidirectional air valve is connected to an air source through an air inlet line. The air source is either inert gas or air, ensuring a stable air supply.

[0018] Based on the above, the relay buffer cavity has an ellipsoidal structure, with its air inlet and outlet located at the long end of the ellipsoidal structure. The cavity volume of the buffer is large enough to ensure the stability of the buffer.

[0019] This utility model has substantial features and advancements compared to existing technologies. Specifically, this utility model improves upon the structure of a traditional olfaction port. First, a one-way blowing valve is added to the air inlet side to guide the airflow to be measured into the relay buffer chamber. Then, two branches are set at the outlet end of the relay buffer chamber: one is an olfaction channel, and the other is an enrichment channel. Both channels are controlled by a two-way blowing valve, so that the olfaction port can meet the needs of simultaneous olfaction and enrichment, or the need to select one of them, thus diversifying its functions.

[0020] Furthermore, the intermediate buffer chamber makes the flow of the gas to be tested smoother and gentler, which facilitates the distribution process of subsequent branches. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] like Figures 1-3 As shown, a multifunctional ODP olfaction port includes an air intake channel 1, a relay buffer chamber 2, an olfaction channel 3, and an enrichment channel 4.

[0027] The air intake channel 1 is connected to the relay buffer chamber 2 through the one-way blowing valve 5, which is used to introduce the gas to be tested into the relay buffer chamber 2. In this embodiment, the one-way blowing valve 5 is an annular valve, including an annular valve body 51 and air outlets 52 evenly distributed on one side end face of the annular valve body. The annular valve body 51 is provided with an air passage 54 that connects each air outlet 52. The side of the annular valve body 51 is provided with an air inlet 53. The orientation of the air outlets 52 is the same as the flow direction of the air intake channel 1.

[0028] The air inlet of the one-way air valve 5 is connected to an air source via an air inlet line, and the air source is either inert gas or air.

[0029] The relay buffer chamber 2 is an ellipsoidal air chamber. The air inlet and outlet of the relay buffer chamber 2 are located at both ends of the long end of the ellipsoidal structure to moderate the airflow velocity, which is beneficial to the airflow distribution of subsequent branch paths.

[0030] The relay buffer chamber 2 is connected to the olfaction channel 3 at the outlet of the first bidirectional blowing valve 6, which is used to introduce the gas to be tested into the olfaction channel 3 or to block the gas from entering the olfaction channel 3. The end of the olfaction channel is detachably equipped with an olfaction hood for the experimental personnel to smell.

[0031] A second bidirectional blowing valve 7 is installed at the outlet of the enrichment channel connected to the relay buffer chamber 2. This valve is used to introduce the gas to be tested into the enrichment channel 4 or to block its entry into the enrichment channel 4. An enrichment chamber, which can be an adsorption tube, absorption belt, collection bag, or collection bottle, is detachably installed at the end of the enrichment channel to collect the gas to be tested. The inlet of the bidirectional blowing valve is connected to a gas source, which can be an inert gas or air, via an inlet line.

[0032] The bidirectional air valve is an annular valve, comprising an annular valve body 51 and two sets of air outlets 52 evenly distributed on the two end faces of the annular valve body. The annular valve body is provided with two air passages 54 that respectively connect the two sets of air outlets. An air inlet is provided on the side of the annular valve body. An active switch 55 for switching between the two air passages is provided at the air inlet. Specifically, an arc-shaped cavity 56 is provided at the air inlet of the annular valve body 51. The active switch 55 is an arc-shaped slider that slides radially with the arc-shaped cavity. Air ports 57 are provided on the two end faces of the arc-shaped cavity corresponding to the two air passages. The arc-shaped slider blocks one of the air ports by sliding.

[0033] Operating principle: When staff need to enrich the gas to be tested while smelling it, they open the one-way blowing valve 5, which controls the air outlet on the side of the first two-way blowing valve 6 facing the outlet end of the smelling channel to open, and at the same time controls the air outlet on the side of the second two-way blowing valve 7 facing the outlet end of the enrichment channel to open, so that the gas to be tested can be transmitted to the two channels simultaneously, achieving smelling and enrichment respectively.

[0034] When staff only need to smell, they open the one-way blowing valve, controlling the air outlet on the side of the first two-way blowing valve 6 facing the outlet end of the smelling channel to open, and at the same time controlling the air outlet on the side of the second two-way blowing valve 7 facing the inlet end of the enrichment channel to open, thereby realizing reverse blowing and preventing the airflow from entering the enrichment channel, thus realizing the single activation of the smelling function.

[0035] Correspondingly, when only enrichment is needed, the other processes are the same, and it is only necessary to control the first two-way blowing valve 6 to open in the reverse direction.

[0036] It should be noted that the movable switch 55 in the first two-way air valve 6 and the second two-way air valve 7 is a toggle switch. The operation is simple and infrequent, and the valve body is not large. Therefore, the execution of this action can be manually completed by manually operating the toggle mechanism derived from the movable switch 55. In experimental environments with high automation requirements, this action can also be completed by electric drive, or a bypass air path can be added. The bypass air path connects to the two cavities separated by the movable switch 55. The toggle action of the movable switch 55 is controlled by the conduction of the bypass air path, similar to the execution action of a two-position two-way valve.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
