Description

Technical Field

[0001] This utility model relates to the field of olfactometer technology, specifically to an ODP olfactometer with a heating component. Background Technology

[0002] During the experiment, residues appeared at the ODP olfactometer. After observation and analysis, it was found that the residues were caused by the fact that when the fraction was drawn out from the high-temperature environment of the column oven, the temperature of the olfactometer was relatively low compared to the temperature of the column oven. Some high-boiling-point substances condensed at the olfactometer, resulting in residues.

[0003] These residues may cause column blockage or affect other aspects of the flow analysis.

[0004] In the past, cleaning and drying steps were usually added after use. However, the air passage is relatively closed, making cleaning more difficult and easily damaging the equipment, which brings difficulties to daily use.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a method that uses auxiliary heating to maintain the temperature at the olfactory opening at a level where the flow fraction is not prone to condensation, thereby avoiding the formation of residual ODP olfactory openings with heating components.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: an ODP olfaction port with a heating component, comprising an ODP olfaction port and an auxiliary heating sleeve; The ODP olfactometer includes an olfactometer glass cover, an air inlet pipe, and an olfactometer body. The outlet end of the olfactometer body is connected to the olfactometer glass cover, and the inlet end of the olfactometer body is connected to the air inlet pipe. The auxiliary heating sleeve includes a sleeve, a heating component, and a movable sealing plate. The sleeve consists of two arc-shaped outer shells with one end hinged together, and the other ends of the two arc-shaped outer shells are openable and closable together for detachably wrapping around the outside of the olfactory port body. The heating component is installed on the inner wall of the sleeve and is used to heat the olfactory opening body; The movable sealing plates are encapsulated at both ends of the sleeve, and circular holes are respectively provided at the center of the movable sealing plates at both ends of the sleeve for the air intake pipe to pass through and the olfactory mouth glass cover to pass through.

[0008] This invention adds a detachable auxiliary heating sleeve to the ODP olfactometer. The auxiliary heating sleeve has a heating component inside and movable sealing plates at both ends. When in use, it is fitted over the outside of the olfactometer body, and the two ends are respectively clipped onto the air intake pipe and the glass cover of the olfactometer to fix it and seal the internal space. By controlling the power of the heating component, the internal temperature is adjusted to effectively prevent the gas from the air intake pipe from condensing and remaining due to temperature difference.

[0009] As described above, the other ends of the two arc-shaped outer shells are connected by magnetic attraction, plug-in connection, or latching. This facilitates assembly and disassembly.

[0010] Based on the above, the sleeve is made of a non-thermal conductive material, and an insulation layer is provided on the inner side of the sleeve to prevent burns to operators.

[0011] Based on the above, the heating component consists of heating wires evenly distributed on the inner wall of the sleeve. This method allows for direct heating via electrical current, resulting in high efficiency and speed.

[0012] Based on the above, a temperature sensor is installed inside the sleeve or on the olfactory port body to detect the internal temperature of the sleeve and provide a reference for adjusting the power of the heating wire. Through the feedback from the temperature sensor, a feedback self-regulation mechanism is established to ensure that the heating temperature remains relatively stable.

[0013] Based on the above, the movable sealing plate includes several metal baffles of equal size. The outer ends of the metal baffles are arc-shaped to fit the end of the sleeve. The inner ends of the metal baffles converge to cover the end of the sleeve and form the circular hole. The outer ends of the metal baffles are hinged to the end of the sleeve via a resistance hinge. This movable sealing plate can be opened and closed relatively easily.

[0014] As described above, a heat insulation layer is provided on the inner end face of the metal baffle. This is mainly used to prevent heat loss.

[0015] Based on the above, the olfactory port glass cover is a cover whose diameter gradually increases from the air inlet end to the air outlet end, and the neck of the olfactory port glass cover passes through the circular hole formed by the metal baffle. The internal volume of the olfactory port glass cover is as large as possible to meet the requirements of airflow and diffusion.

[0016] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model adds a detachable auxiliary heating sleeve at the ODP olfaction port. The auxiliary heating sleeve is equipped with a heating component inside, which can realize the adjustment of the internal temperature and effectively avoid the condensation and residue of the gas transmitted from the air intake pipe due to the temperature difference.

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0022] like Figures 1-3 As shown, an ODP olfaction port with a heating element includes an ODP olfaction port and an auxiliary heating sleeve. The ODP snorting port includes a snorting port glass cover 1, an air inlet pipe 2, and a snorting port body 3. The outlet end of the snorting port body 3 is connected to the snorting port glass cover 1 for providing a snorting experience for the testing personnel. The inlet end of the snorting port body 3 is connected to the air inlet pipe 2 for receiving the gas to be tested blown from the upstream equipment.

[0023] The auxiliary heating sleeve includes a sleeve 4, a heating component 5, and a movable sealing plate 6. The sleeve 4 consists of two arc-shaped outer shells, one end of which is hinged to each other by a structure such as a hinge. The other ends of the two arc-shaped outer shells are connected together in an openable and closable manner for detachably wrapping around the outside of the olfactory port body.

[0024] Specifically, in this embodiment, the other ends of the two arc-shaped shells are connected together by magnetic attraction. In other embodiments, they can also be connected by plugging or locking.

[0025] In this embodiment, the sleeve is made of a non-thermal conductive material, and an insulation layer is provided on the inner side of the sleeve to prevent heat loss and maintain a stable internal ambient temperature.

[0026] The heating component 5 is installed on the inner wall of the sleeve. In this embodiment, it is an electric heating wire evenly arranged on the inner wall of the sleeve, used to heat the olfactory opening body.

[0027] In terms of control, a temperature sensor (not shown in the figure) is installed inside the sleeve 4 or on the sniffing port body 3 to detect the internal temperature of the sleeve 4 and provide a reference for adjusting the power of the heating wire.

[0028] The movable sealing plate 6 is encapsulated at both ends of the sleeve 4. At the center of the movable sealing plate 6 at both ends of the sleeve 4, there are circular holes 7 for the air intake pipe 2 to pass through and the olfactory glass cover 1 to pass through.

[0029] Specifically, in this embodiment, the movable sealing plate 6 includes several metal baffles of equal size. The outer end of each metal baffle is an arc shape adapted to the end of the sleeve. The inner end of each metal baffle closes up to cover the end of the sleeve and form the circular hole 7. The outer end of each metal baffle is hinged to the end of the sleeve through a resistance hinge, so that the metal baffle can be suspended at any angle without the application of additional structures. This allows it to converge into an integral baffle when closed, and effectively support the outer wall of the air intake pipe 2 and the outer surface of the olfactory port glass cover 1. When unfolded, it can be opened so that the entire sleeve can be easily removed.

[0030] To prevent heat loss, in a preferred embodiment, a heat insulation layer is provided on the inner end face of the metal baffle.

[0031] To ensure that the size of the circular hole is not too large, in a preferred embodiment, the olfactory port glass cover is a cover with a diameter that gradually increases from the air inlet end to the air outlet end, and the circular hole formed by the metal baffle passes through the neck of the olfactory port glass cover.

[0032] Explanation of operating principles: The two arc-shaped outer shells of the sleeve are unfolded through the hinge end. At this time, the movable sealing plate 6 at the end is in the unfolded state. Then, the sleeve is surrounded outside the olfactory opening, and the two arc-shaped outer shells are closed by using the magnetic attraction force at the other end.

[0033] At the same time, adjust the metal baffles at both ends so that the circular holes 7 formed by the metal baffles close and surround the outside of the air intake pipe 2 and the outside of the olfactory port glass cover 1. The size of the circular holes is comparable to the outer diameter of the air intake pipe 2 and the neck size of the olfactory port glass cover 1. On the one hand, it is used to pass through the circular holes, and on the other hand, it can serve as a support point for the entire sleeve, ensuring that the olfactory port body is located in a relatively central position inside the sleeve.

[0034] Then adjust the heating component 5 to heat the internal environment. It is best to adjust it according to the inlet temperature of the airflow to make the two temperatures the same, thereby avoiding some of the airflow condensing inside the olfaction port.

[0035] Under normal circumstances, the temperature of the flow sample is within a safe range that the human body can tolerate. Of course, the airflow temperature can also be cooled by setting the neck length of the sniffing nozzle glass cover. By changing the sniffing nozzle glass cover to different lengths, it is possible to avoid the temperature from being too high and burning the testing personnel.

[0036] Furthermore, a notch structure for threading can be added to the closed end of the sleeve to facilitate the wiring of the olfactory port body, the heating component, and the temperature sensor.

[0037] In some embodiments, to ensure the sealing of the round holes at both ends, a substance such as gel can be used to temporarily seal the gap.

[0038] 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.
