Description

Technical Field

[0001] The present invention relates to the technical field of odor detection devices, and in particular to a multi-dimensional analog experiment device for odor properties and an analog device thereof. Background Art

[0002] Smell is a basic element in daily life. People can feel it every time they breathe. However, it is difficult to feel and experience it because we cannot see it most of the time. In daily life, smell is a manifestation of many material properties. The study of smell is a very important part of studying the properties of materials. However, among the research tools of smell discipline, there is no mature smell analogy and detection device based on physical mechanical principles on the market.

[0003] When people undergo physical examinations, they also need to make judgments about their sense of smell. The tester holds up three bottles that look exactly the same, each containing pure water, acetic acid, and ethanol. Through olfactory analysis, the tester uses words to describe the types of smells perceived to determine whether the student's sense of smell is abnormal. This method is relatively simple and direct, and cannot identify and recognize multiple odors. In addition, in a higher-level olfactory recognition test, there is a "paper strip test method" in which "smearers" judge the sensitivity to odor concentration by tasting paper strips dipped in olfactory standard liquid and odorless liquid. As a disposable product exposed to the air, this "smell strip" inevitably has large errors, which reduces the accuracy of the test. Summary of the invention

[0004] In view of the above-mentioned defects or shortcomings, the object of the present invention is to provide a multi-dimensional analogy experimental device for odor properties and an analogy device thereof, which can analyze and compare a variety of odors.

[0005] To achieve the above purpose, the technical solution of the present invention is:

[0007] The liquid gas source tube comprises a first gas source tube shell, wherein a hollow sleeve is sleeved inside the first gas source tube shell, and a smelly sample slice is clamped inside the hollow sleeve.

[0008] The odor sample slice comprises a liquid slice, and the liquid slice comprises a slice test paper. Both ends of the slice test paper are provided with card slots for surrounding and clamping, and a fiber layer for dripping the liquid odor sample is provided in the slice test paper.

[0009] The odor sample slice comprises a solid slice, and the solid slice comprises an upper mesh metal slice and a lower mesh metal slice, and the solid odor sample is sandwiched between the upper mesh metal slice and the lower mesh metal slice.

[0010] The inner wall of the hollow sleeve is provided with a clip for fixing the odor sample slice.

[0011] The gas source bottle comprises a bottle body, on which a branch connection port for mixing gas is arranged; the upper and lower ports of the bottle body are both provided with threaded interfaces connected with a gas supply device and a playback device.

[0012] The air supply device comprises a peristaltic pump installed in the base, and the outlet of the peristaltic pump is connected to the filtering device.

[0013] The playback device comprises a hemispherical mask installed on the top of the air source pipe, an exhaust fan, an air pump and a piston conversion hole installed on the outlet of the air source pipe.

DETAILED DESCRIPTION

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0043] Embodiment 1

[0044] like Figure 1 As shown, the present invention provides an odor property exploration and multi-dimensional analog device, including a base 1, on which a rotatable turntable 2 is installed; a plurality of fixed frames 4 are arranged along the circumference of the turntable 2, and an air source mechanism 5 for collecting odors is installed on the fixed frame 4; wherein the air source mechanism 5 includes an air source tube 9, in which an odor sample is installed, the inlet of the air source tube 9 is connected to an air supply device 6 and a filtering device 17, and the outlet of the air source tube 9 is connected to a playback device 8; the air source tube 9 is a solid-liquid air source tube 91, or a gas source bottle 92. wherein, the type of slice of the sample in the air source tube 9 can be switched according to the actual application.

[0045] For solid and liquid gas source pipe 91:

[0046] Specifically, Figure 2As shown in the figure, the solid-liquid gas source tube 91 in the present invention includes a first gas source tube housing 911. Inside the first gas source tube housing 911, a hollow sleeve 912 is sleeved, and an odor sample slice 913 is clamped inside the hollow sleeve 912. The hollow sleeve 912 is a hollow sleeve made of plastics. The optimal choices for the materials of plastic products are all polytetrafluoroethylene, polyester, and polypropylene, or it is made of metal. The inner side of the housing is attached with a fiber layer such as sponge or cotton that has a strong expansion ability for liquids. The innermost part is a hollow pipe that ensures smooth airflow. Therefore, the liquid gas source tube can be divided into three layers: a hard outer shell, a liquid fiber diffusion layer, and a hollow inner layer.

[0047] As Figure 3 shown, the odor sample slice 913 includes a liquid slice. The liquid slice includes a slice test paper 914. Clamping grooves 915 that are surrounded and clamped are arranged at both ends of the slice test paper 914. A fiber layer 916 for dripping a liquid odor sample is arranged in the slice test paper 914. It should be noted that in the present invention, the plastic liquid gas source tube is disassemblable and freely assembled, and various experimental potions that can be perceived by the human sense of smell (reaching the threshold) can be dripped arbitrarily. Structurally, assume that when the "liquid gas source tube" is unfolded, it is a rectangle with a length of xmm and a width of ymm. From both the left and right ends of the rectangle, small rectangles with a unit width of amm and a length of ymm are intercepted. The area where a < x is the "adhesive area", then the rectangle in the middle area with a length of x - 2amm and a width of ymm is the experimental area. A fiber tissue with good water absorption performance is closely laid in the experimental area in terms of technology. When making the slice test paper 914, any one or a mixture of potions can be evenly dripped on the experimental area. After smearing the potions evenly, cut bmm < b < y along the two intersection lines between the adhesive area and the experimental area from top and bottom respectively. Note that cut bmm from top to bottom on one side and cut bmm from bottom to top on the other side. During the process of manufacturing, in order to prevent the errors and troubles brought by the user's own cutting, machine cutting can be carried out at the experimental area and the adhesive boundary line from top to bottom during manufacturing. As Figure 4 shown, after the user evenly smears the potion, the left and right ends can be overlapped, and the upper and lower two notches can be inserted错位 to form a hollow cylinder; a clip 917 for fixing the odor sample slice 913 is arranged on the inner wall of the hollow sleeve 912, as Figure 5 shown.

[0048] As Figure 6 shown, in the present invention, the odor sample slice 913 includes a solid slice. The solid slice includes an upper reticulated metal slice 918 and a lower reticulated metal slice 919. The solid odor sample is clamped between the upper reticulated metal slice 918 and the lower reticulated metal slice 919.

[0049] Preferably, the solid slice is divided into a transverse slice and a longitudinal slice, as Figure 7 As shown, for transverse slicing, two pieces of stainless steel or other anti-corrosion treated mesh metal slices are cut, and a solid odor source slice is precisely sandwiched in the middle. The bottom of the first gas source tube shell 911 is twisted in the tube through a threaded interface. When making the odor slice, the solid odor source must be cut into a slice as thin as possible to ensure a certain amount of airflow passing through; Figure 8 As shown, longitudinal slicing is to insert the slicing clip into the outer shell tube and fix it close to the inner wall of the ellipsoidal body, so that when the airflow is input from the lower pipe or the air expansion funnel, more small particle odor molecules emitted by the odor source can be taken away. For longitudinal slicing, the clips 917 mentioned above can be arranged up and down on the inner wall of the hollow sleeve 912, such as Fig. 9 shown.

[0050] For gas source cylinder 92:

[0051] like Fig.10 As shown, the gas source bottle 92 includes a bottle body 921, on which a branch connection port 922 for mixing gas is provided; the upper and lower ports of the bottle body 921 are both provided with threaded interfaces connected to the air supply device 6 and the playback device 8.

[0052] Exemplarily, the gas source pipes in the present invention are divided into two categories:

[0053] One type has a metal interface at the top and bottom, and the whole is a glass cylinder. The interface of the gear-changing air supply device at the bottom is directly connected with a rubber tube. Open the valves on the upper and lower metal interfaces to discharge the gas stored in the tube that has reached the threshold odor. This type of gas source tube is also called a storage type gas source tube. Under this type of storage type gas source tube, there is also a disposable vacuum bottle sampler that can be connected to the upper and lower sections.

[0054] Another type of glassy gas source tube has a branch tube at the top or bottom of the gas source tube, and the branch tube can be on the same side or on the opposite side. This gas source tube can be connected to other chemical devices that generate gases that can be sensed by human olfaction. At this time, the gas source tube is like a multifunctional bottle or a gas washing bottle in a chemical experiment in terms of function and operation. According to different chemical reaction requirements, a gas source tube with different branches is selected. Among them, the branch tube can be connected to various specifications of tetrafluoroethylene gas sample collection of the three-point comparison collection belt method.

[0055] In addition, there is an ASTM syringe-collection type gas source tube, such as Fig.11As shown, this ASTM syringe-collection type air source tube does not need to rely on the air delivery device 6 of the base when in use, but uses the physical and mechanical compression device carried by itself to slowly compress the air in the syringe that carries the odor molecules out in the form of a syringe. At the same time, when in use, it is necessary to simultaneously unfold at least three or more air source tube caps on the odor microscope rotating fragrance wheel. The upper part of this cap is a metal tube with a valve, which can be connected to other filter tube structures. The lower part of the playback device 8 is a long bottle cap-style threaded structure, which can be connected to the ASTM syringe-collection type air source tube with its knob. At the same time, this long bottle cap also has a long rubber plug with a channel inside, which can ensure that the ASTM syringe needle is inserted. In order to fix the ASTM syringe-collection type air source tube from falling, a grid bag can be added and suspended on the connecting iron rod to fix it.

[0056] In the device for exploring the properties of odors and for multi-dimensional analogy, a retractable support rod 3 is installed on the rotating platform 2, and a support frame 7 for connecting to the top of the gas source pipe 9 is installed on the support rod 3. Fig.12 As shown, 6-8 fixing frames 4 are arranged along the circumference of the rotating table 2 and are fixedly connected to the gas source pipe 9 of the research department, and can be freely rotated and replaced with different gas source pipes 9. In addition to the first layer of 6 or 8 different types of gas source pipes 9 with fixing frames 4 fixed on a rotating incense wheel when leaving the factory, it can also be a free assembly joint, such as a directly rotating threaded joint matched with the fixing frame 4 on the gas source pipe 9 or a translation from top to bottom, so that the connecting rod near the steering wheel end is horizontally pushed into the stuck groove.

[0057] like Fig.13 As shown, the air supply device 6 includes a peristaltic pump 10 installed in the base 1, and the outlet filter device 17 of the peristaltic pump 10 is connected. The exhaust volume of the peristaltic pump is at least 10L / min. The filter device 17 is an air expansion funnel, which is a small instrument that can be connected to the peristaltic pump through a rubber hose, and the other end is larger with a threaded port that can be connected to the air source pipe 9 for rotation, and an activated carbon net is provided in the middle to filter air. The jet outlet of the variable gear peristaltic pump is connected to the air expansion funnel by a rubber conduit. The air expansion funnel is connected to the bottom of the air source pipe connected to the same rotating fragrance wheel, and the connection method can be a tight sleeve or a threaded rotation, and the air expansion funnel is rotated to the air source pipe in two ways. The air expansion funnel is a small instrument that can be connected to the peristaltic pump through a rubber hose, and the other end is larger with a threaded port that can be connected to the air source pipe 9 for rotation, and an activated carbon net is provided in the middle to filter air. The 6 to 8 air source pipes connected to the outer ring of the bearing of the rotating table 2 can rotate alternately. When connected to the gas expansion funnel, rotate the gas expansion funnel to rotate it at the bottom of the gas source tube. Fig.14 shown.

[0058] Exemplarily, the filter device 17 may have three types of dust removal pipes that may be added to the upper end or the lower end of the "air source pipe".

[0059] The first type is a gas filter bottle, which can remove dust from the gas sample, such as Fig.15 As shown in a.

[0060] The second type is a filter cover made of metal mesh, which is used to remove dust from gas samples, such as Fig.15 As shown in b.

[0061] The third type is a filter tube made of glass wool, which is used to remove dust from gas samples, such as Fig.15 As shown in c.

[0062] In addition, it can also be a blower with heating and multiple gears. Its power supply relies on a wire with a three-hole socket to directly connect to the laboratory student power supply or household power socket. The blower can switch between hot and cold winds and can flexibly adjust the wind speed in 4 to 8 different gears.

[0063] The rotatable turntable 2 is free to rotate 360°. Specifically, a rotatable bearing is installed on the base 1. Preferably, a retractable support rod 3 is installed on the turntable 2, and a support frame 7 for connecting with the top of the air source pipe 9 is installed on the support rod 3, which is used to perform secondary fixation on the long structure of the air source pipe 9 to stabilize its position and prevent it from tipping over during tasting.

[0064] like Fig.16 As shown, the playback device 8 includes a hemispherical mask 81 installed on the top of the gas source pipe 9, an exhaust fan 82, an air pump 83, and a piston conversion hole 84 installed on the outlet of the gas source pipe 9. A filter layer 18 can also be installed in the playback device 8. The material of the filter layer 18 can be "acetate fiber" used in cigarette filters as the first choice. An external odor detector or sensor can be installed. The first function is to detect gas components, and the second function is to prevent researchers from inhaling toxic gases. The air pump 83 can be divided into two types: manual and electric. The manual one is an extrusion exhaust piston or a manual pumping rod piston. According to the needs of the experimenter's personal olfactory perception, the gas overflow speed is controlled by the squeezing force or pulling frequency of the piston with the idle hand, which indirectly controls the odor diffusion speed. The air extraction hole is located at the top center of the entire device, covered with a hemispherical mask 81, the cover can be disassembled and cleaned, and a layer of fluff structure similar to the inside of the lens hood of a single-lens reflex camera is built in, which plays the role of electrostatic dust removal.

[0065] The exhaust fan 82 is used to change the vertically rising airflow carrying odor molecules into a horizontal airflow, so that the experimenter can directly sense it with his sense of smell. The principle of this way of olfactory odor perception is exactly the method of sensing the odor of the gas in the gas collection bottle in the laboratory - the principle of the fan smelling method. This method prevents the strong irritating odor gas from directly irritating the mucous membrane inside the nasal cavity.

[0066] It should be noted that the smell property exploration and multi-dimensional analog device can add several sets of filtering devices according to the actual experimental needs. The telescopic mast can be freely extended and retracted, similar to the structure of the laboratory iron frame, and can be freely connected and combined with the uppermost section of the freely combined smell experimental device by means of an iron ring with adjustable circumference and an iron clamp with variable tension.

[0067] The working process of the device of the present invention is:

[0068] 1. Place the odor property exploration and multi-dimensional analogy device on the desktop, connect the peristaltic pump or blower power supply of the base, 220V household power supply or student power supply;

[0069] 2. Select the appropriate gas source tube according to the nature of the odor source to be studied.

[0070] Before the experiment, the experimenter's arms need to be washed with odorless soap. The experimenter needs to open the windows for ventilation and breathe fresh air to prevent olfactory fatigue and maintain sensitivity to odors within the maximum range.

[0071] Daily steps for cleaning the gas source pipe: neutral cleaning liquid → water alkali solution (10% sodium hydroxide) → potassium dichromate cleaning solution → boiling water → flushing with water → ethanol → acetone → drying

[0072] (1) Since the application field requires mostly "perfume", the "liquid gas source tube" is the most widely used. Spread the "replaceable plastic (polytetrafluoroethylene) liquid gas source tube" on a clean glass plate, apply the perfume that reaches the experimenter's odor threshold concentration evenly to the experimental area, then fold the two ends, alternately inlay the notches on the left and right ends of the adhesion area, and then firmly hang it on the hollow tube of the cylinder, and connect the other sections from the top and bottom in a spiral twisting manner.

[0073] (2) The method of using the gas source tube for ordinary storage gas is: rotate the threads at the upper and lower ends of the gas source tube together with the upper and lower sections. When using it, first open the upper and lower pistons, and then turn on the peristaltic pump or multi-speed blower to ensure that the airflow passes directly through this section to the upper section through the rubber tube and the air expansion funnel.

[0074] The method of using the common collecting gas source tube is: according to the experiment to be performed, choose different types of collecting gas source tubes with the same side or different side, with upper or lower branches, and rotate and connect them with the upper and lower sections.

[0075] The method of using the "ASTM syringe - collection type gas source tube" is: turn the aroma wheel to spread out 3 to 4 "gas source tube caps", store the gas carrying odor molecules collected by the ASTM syringe in this type of gas source tube, and then rotate it on the gas source tube cap, and hang it upside down on the iron rod with a mesh sling to ensure that the needle of the ASTM syringe can pass through the pipe of the rubber piston in the gas source tube cap.

[0076] (3) How to use the gas source tube for horizontally slicing solids: When making slices, cut the solid odor source into slices as thin as possible, and use a dissecting needle to pierce multiple needle holes to ensure smooth airflow. Clamp it tightly with two layers of slicing clamps, and then rotate it in the upper and lower cylinders.

[0077] How to use the longitudinally sliced ​​solid odor tube: The production method is basically the same as above, but the longitudinal slice may be clamped into a curved surface. The solid odor source needs to be bent into a curved surface that can cover the inner surface of the saddle surface, and it does not necessarily need to be pierced with a dissecting needle. When it is tightly attached to the upper saddle surface, close the lower page and then hang it firmly in the odor tube.

[0078] 3. According to the needs of the desired odor experiment, twist the knob on the upper section to add more filtering devices.

[0079] 4. According to the needs of comparative experiments, multiple sets of experimental equipment can be used on the rotating incense wheel at the same time. The customized version can push the gas source tube device with the connecting iron rod from top to bottom into the card slot or screw knob to fix it on the rotating incense wheel. According to the actual length of the carrying device, control the length of the telescopic mast, and connect its upper end with the expansion funnel to ensure its fixation.

[0080] 5. Install the "aroma tasting device" with an odor microscope equipped with a vacuum pump, exhaust fan and hemispherical cover at the top of each experimental device. Connect the vacuum pump and exhaust fan of the power device to the student power supply.

[0081] 6. Turn on the peristaltic pump or multi-speed blower to ensure smooth airflow through the air source pipe and filter pipe to the upper vacuum pump, keep the laboratory ventilated, and turn on the exhaust fan.

[0082] 7. The experimenter leans forward and puts his nose near the top of the device to judge whether the gas is toxic by "fanning and sniffing". It can also be used to verify whether the gas is toxic or flammable and explosive. However, most experiments used to analyze odors are for non-toxic and odorous gases.

[0083] 8. After determining that the gas has no odor, you can adjust the variable-speed blower to hot air or a higher gear, or turn up the gears of the vacuum pump and exhaust fan.

[0084] After the experiment, dismantle the device, carefully clean and store the air source tube with odorless air, and put all experimental equipment back in place.

[0085] Note: If you sense foul-smelling gases, due to the experience accumulated by humans during millions of years of evolution, many foul-smelling gases often carry "toxins". Therefore, when you smell a certain odor, the experimenter should be highly vigilant. Once you feel any physical discomfort, immediately turn off the peristaltic pump (blower) and the upper vacuum pump and exhaust fan, and open the window for ventilation.

[0086] At the same time, you should also remain vigilant about unfamiliar odorless gases. If you feel any physical discomfort, stop the experiment and repeat the above steps.

[0087] Embodiment 2

[0088] like Fig.17 As shown, the present invention provides a multi-dimensional analog device for odor properties, which can be divided into three types: entertainment type, commercial type, and medical type, including a plurality of rotatably connected columnar shells 11, an odor sample unit 12 is radially arranged along the inner wall of each columnar shell 11, a plurality of odor sample capsules 13 are installed on the edge of the odor sample unit 12, a baffle layer 15 is arranged below the odor sample unit 12, and a gap is arranged between one side of the baffle layer 15 and the columnar shell 11; a micro exhaust fan 14 is installed inside the bottom columnar shell 11, and a power supply is connected to the micro exhaust fan 14; an air outlet 16 is provided on the top columnar shell 11, and the air outlet 16, the micro exhaust fan 14 and the gap are located in the same straight line;

[0089] Entertainment type: Specifically, the entertainment type is connected by a bearing or a rubber piston, and a micro exhaust fan 14 powered by two built-in No. 7 or No. 5 batteries provides uniform wind force of different gears at the bottom. The wind of different gears will go straight through the vent to the nose support fragrance mouth at the other end. In the middle of the whole, there are three rotating fragrance wheels that can rotate 360°. There are different odor-isolating edge layers in the middle of the three steering wheels, which are connected in the middle by bearings and can rotate 360°. The air outlet 16 is a cover that can be highly matched with the bridge of the nose in bioengineering. There is a hole in the inside that can be replaced by rotation. The hole is in a horizontal straight line with the bottom fan. This channel is called the inner court channel. If the vacant holes of the three rotating fragrance wheels are rotated on the inner court channel at the same time, the bottom airflow can be blown directly outside the fragrance mouth.

[0090] The plurality of rotatably connected cylindrical shells 11 are connected by bearings or rotating shafts. One is a metal bearing. The three bearings uniformly connect the inner ring or outer ring with the main rod, so as to achieve the purpose of freely switching the "liquid gas source pipe" on each layer of the "rotating incense wheel". Fig.18As shown, the other is a rubber piston, which is lighter than a metal bearing.

[0091] When using it, players need to put their nose close to the exhaust port at the other end, turn on the power switch, and the bottom fan will rotate, forming an airflow with a certain wind speed from the bottom of the aroma tasting channel. Rotate the three rotating aroma cylinders separately, and each rotating aroma cylinder has several aroma adjustment circles (one of the aroma adjustment circles is empty to ensure that the airflow can pass directly. Reset the empty aroma adjustment circles of the other two rotating aroma wheels with the single air source tube of another rotating aroma wheel, so that a single smell can be tasted.)

[0092] In addition, the odor sample capsule 13 can be provided with a groove channel that can hold the liquid gas source tube, and a small hook that matches it is built into each channel where the liquid gas source tube is placed, and a homemade temporary liquid gas source tube or a permanent gas source tube is horizontally pushed into each fixed position, and it is firmly hung with a hook fixed at each position. The gas source tube can be a filter paper gas source tube or a cotton gas source tube according to the material of the liquid diffusion layer, and gas source tubes of different fiber materials are made according to parameters such as the permeability of different experimental potions. The gas source tube can be divided into two types: permanent gas source tube and temporary gas source tube according to the number of experimental uses. The permanent gas source tube is uniformly produced by the factory and can be used as a fixed odor slice of an entertainment type or commercial type and a medical detector. The entertainment type and commercial type odor kaleidoscope can also be divided into two types: fixed type and open type, that is, analogous to the permanent slice and temporary slice of an optical microscope; the permanent gas source tube is uniformly produced by the factory and can be used as a fixed odor slice of an entertainment type or commercial type and a medical odor tube detector, and the entertainment type and commercial type odor kaleidoscope can also be divided into two types: fixed type and open type.

[0093] Fixed type: the whole device is sealed and fixed, and you only need to replace the battery regularly and rotate the three aroma wheels to freely combine. In the entertainment type, based on the principle of economy and affordability, the normal use of the scent toy is guaranteed before the scent liquid evaporates in half a year to a year. For economic and practical considerations, it is only necessary to provide players with a few fixed smells that are popular with the public to meet the design requirements based on this design concept. At the same time, the number of aroma wheels can be appropriately reduced.

[0094] Commercial type: At the same time, such as the commercial sale of air purifiers with fixed scents, or the analog display of different scents of the same type of cosmetics, etc. In order to ensure the richness and authenticity of the scent, perfume manufacturers can produce more refined high-end business areas than entertainment types, providing customers who choose scented cosmetics with a more elegant and accurate shopping method to choose cosmetics that suit their own scent.

[0095] Compared with the original method of applying them on the palms respectively and smelling them in turn, this high-end business model that carries different scented liquids produced by the original manufacturer can also be used for new product samples provided by the technical research and development department to the front-line sales department, or for samples shown to major customers, which can make their products stand out in the fiercely competitive market.

[0096] Medical type: Medical detection of olfaction requires tightness. A national standard medical detector can be equipped with six fixed channels with permanent gas source tubes on a rotating aroma wheel, five of which are different dilution concentrations of the same odor substance, and the other is a blank control. One layer of the rotating aroma wheel can be loaded with different concentrations of diluted ethanol, and the other layer can be loaded with different dilution concentrations of acetic acid.

[0097] The medical odor kaleidoscope detector is mainly used in medical olfactory testing. To meet the detection needs of different dilution concentrations of the same odor substance, different gears of fans can be turned on for the same air source tube in the same channel to increase the diffusion frequency of odor molecules.

[0098] At the same time, medical smell kaleidoscopes are different from entertainment and commercial smell kaleidoscopes in that they have higher requirements for insulation barriers and are more stringent in manufacturing.

[0099] Preferably, the medical CCCRC confirmation threshold detection of the medical category of the present invention - odor kaleidoscope detector:

[0100] like Fig.19 As shown, the CCCRC olfactory test is divided into detection threshold and confirmation threshold test. Among them, the confirmation threshold test uses 8 kinds of daily items as olfactory objects: prickly heat powder dilution, cocoa juice, cinnamon extract, coffee, mothball solution, cream, peanut butter, toothpaste, soap, black pepper solution, and tobacco dilution. These eight solutions are made into air source tubes in the form of permanent air source tubes or temporary air source tubes and mounted on medical odor converters. The special structure of this medical CCCRC confirmation threshold detection-odor detector is that there is only one rotating aroma wheel, but there are nine channels for placing air source tubes on a rotating aroma wheel (one of which is still a blank idle channel.) At the same time, there are two holes on the aroma tasting device of this medical CCCRC confirmation threshold detection-odor kaleidoscope detector, both of which can be closed separately.

[0101] Generally speaking, the fixed type only considers the effective preservation of the scent within a shelf life, so the gas source tube can be made more delicately, and the perfume dripped into the liquid diffusion fiber layer can be more purified and richer.

[0102] In terms of whether the internal gas source pipe can be replaced, the mechanical form can be divided into two categories: fixed type and open type.

[0103] In addition to the fixed type, there are three types of "open types" that can be disassembled and replaced

[0104] 1. Direct plug-in

[0105] like Fig. 20 As shown, this connection method has the lowest cost, but it is easy to fail prematurely due to internal odor leakage caused by poor sealing. That is, the entire device is a series of tubes spliced ​​together. Each tube with an insulation layer is slightly smaller than the bearing or rubber piston for mounting the gas source tube. When the rubber piston is pushed into the next tube, it fits perfectly and ensures that the outer wall is smooth. With this method of splicing tubes one by one, when the internal gas source tube needs to be replaced, the section where it is located can be disassembled, and then spliced ​​together after the replacement is completed.

[0106] 2. Interlayer pipe splicing

[0107] This structure is to design each section of the outer wall pipe of the insulation layer into two semicircular combinations that can be spliced. That is, one half has two protrusions and the other is a groove that can match them. The two are inlaid to form a seal.

[0108] like Fig.21 As shown, when replacement is needed, open the corresponding section and remove the air source pipe firmly hung on the aroma wheel. After replacement, close the section and continue to use it.

[0109] 3. Revolver

[0110] like Fig. 22 As shown, it is similar to the way of pulling out the magazine to change bullets in a revolver. A self-locking rod is set in each section of the whole barrel. During normal use, the self-locking rod is closed to ensure that the incense wheel can rotate 360 ​​degrees freely.

[0111] When the air source pipe needs to be replaced, rotate each section of the self-locking rod to the same horizontal straight line, press the mechanical button, and the locking rod with a spherical thin rod originally retracted in the bore of each section of the self-locking rod will pop out and sink into the corresponding grooves of the upper and lower sections. At this time, push the aroma wheel to the left. After replacement, push the aroma wheel back to release the self-locking rod and continue to use it.

[0112] The working process of the present invention is:

[0113] Commercial and recreational scent tubes come in direct contact with the nose and should never be used to taste any "toxic gases".

[0114] 1. Put two AA batteries or AA batteries into the scent tube.

[0115] 2. Wash your arms with odorless soap to keep the air ventilated to avoid olfactory fatigue before the experiment.

[0116] 3. The method of making the plastic liquid gas source tube is as above. After making it, hook it tightly on the channel of the "rotating incense wheel".

[0117] 4. Open type scent diffuser, open and replace the gas source tube:

[0118] (1) Direct plug-in scent tube with the same usage method:

[0119] Pull each section of the tube off the incense wheel, use tweezers to replace the plastic liquid gas source tube with a new liquid gas source tube, and use tweezers to firmly hang it on the hook of the inner channel of the steering wheel in the same way. Use this method to replace the gas source tube that needs to be replaced. Then reassemble each section of the tube with the steering wheel.

[0120] (2) How to use the interlayer pipe splicing scent tube:

[0121] In the middle of every two sections of the aroma wheel is the interlayer tube of the scent tube, which is made of two semicircular surfaces. Use your fingers to dig into the joint to break the protrusion on one side from the groove on the other side, open the interlayer tube, expose each channel tube on the aroma wheel, and then use tweezers to remove the plastic liquid type gas source tube inside and replace it with a new one. Then connect the two semicircular parts together and lock them tightly.

[0122] (3) How to use the left-hand rotating scent tube: rotate each section of the self-locking rod to the same horizontal line, press the mechanical button, open the self-locking rod to fix all sections of the tube. Push the aroma wheel to the left, so that the aroma wheel rotates and pushes out with the self-locking rod as the axis. Use tweezers to remove the plastic liquid gas source tube inside and replace it with a new one. After the replacement is completed, rotate it back into the tube in the opposite direction to release the self-locking rod.

[0123] 5. Place the "nasal mask aroma mouth" of the "smell rotating incense cylinder" next to your nose, and rotate it to adjust the size of the aroma mouth. Rotate the empty tracks of the other two aroma rotating wheels onto the "inner courtyard channel", and then rotate the other aroma rotating wheel channel with the air source tube installed onto the "inner courtyard channel".

[0124] 6. Turn on the switch, turn on the first gear of the fan, and smell it. If you need to compare a single smell with different smells, rotate the aroma wheel in turn to switch.

[0125] 7. If you need to taste different kinds (two or three) of mixed aromas, rotate the other aroma wheels in turn to taste them one by one.

[0126] Medical use:

[0127] Clean the equipment strictly according to the above instructions for cleaning equipment.

[0128] Wash your arms as described above for the experimenter's arms;

[0129] Open windows for ventilation to prevent olfactory fatigue of subjects before use.

[0130] Place the aroma mouthpiece with a nasal mask around the nasal cavity. Follow the above method, leave the other two aroma wheels empty, rotate the lowest concentration air source tube on one aroma wheel on the "Inner Courtyard Channel", rotate to increase the concentration in sequence, fill in the corresponding options on the medical test form, and hand it over to the responsible physician after completion.

[0131] According to actual testing needs, the base multi-speed fan can be turned on.

[0132] After completing a test, according to actual testing needs, the empty part of the tested aroma wheel is rotated back to the "inner court passage", and another aroma wheel is rotated in the same way.

[0133] Medical CCCRC confirmed threshold detection-How to use the odor kaleidoscope detector: Other usage methods are the same as other odors and medicine, the difference is that these eight substances need to be named.

[0134] The experimenter first closes one channel and selects the other nostril for analysis. The two nostrils are tested separately and the substances smelled are named. The responsible doctor can remind the name of the substance. All the time for confirming the threshold value needs to be completed within 15 minutes, and the score is calculated. The test results of the detection threshold test with butanol as the olfactory substance are combined to produce a comprehensive score, with a score ranging from 0 to 7, indicating from anosmia to normal.

[0135] It is obvious to those skilled in the art that the above-mentioned specific examples are only preferred embodiments of the present invention. Therefore, the improvements and changes that may be made by those skilled in the art to certain parts of the present invention still embody the principles of the present invention and achieve the purpose of the present invention, and all belong to the scope of protection of the present invention.
