Description

Technical Field

[0001] The utility model relates to the technical field of aroma detection odor scanners, and particularly relates to an odor scanner applicable to aroma detection. Background Art

[0002] Aroma, in short, is a natural therapy that uses the aroma of plants to create a specific atmosphere or achieve the purposes of relaxing the body and mind, improving sleep quality, enhancing mood, etc. Its principle is that different plant aromas can stimulate the olfactory nerves in the brain, thereby triggering a series of physiological and psychological reactions. During the production process of aroma, generally, some finished products in each batch of aroma are extracted and used for odor detection of the aroma by an odor scanner to ensure the quality of the aroma products.

[0003] For example, a tea aroma detection device with the publication number of CN220419295UA includes a detection device body. The detection device body includes a detection box, a tea sample box, a deodorization component, and an odor scanner. A partition is installed at the bottom of the detection box. A diversion pipeline is connected to the top of the detection box. The odor scanner is installed at the end of the diversion pipeline. A deodorization component is connected to the side of the bottom of the detection box, and the inside of the deodorization component is communicated with the bottom space inside the detection box. A cover plate is installed on the side of the detection box. In this tea aroma detection device, the tea samples to be detected are placed inside the tea sample box. Therefore, it can avoid the adhesion of tea sample residues to the inner wall of the detection box during the subsequent detection process, reduce the interference to the subsequent cleaning process and the next detection process, and use a third partition net and a fourth partition net to block the top and bottom of the tea sample box respectively, improving the concentration of the tea samples.

[0004] For the existing aroma odor scanners, when detecting the aroma odor, the operator needs to manually take a specific amount of samples from the aroma samples, and then manually install or place the detection sample storage container. The operation is troublesome, and due to the installation of the storage container taking a certain amount of time, during the installation, placement, and movement of the storage container, a small amount of aroma will escape, thus affecting the accuracy of the detection results.

[0005] The purpose of the utility model is to provide an odor scanner applicable to aroma detection to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An odor scanner applicable to aroma detection includes a constant temperature chamber and an odor scanner body.

The bottom end of the conduit is slidably sleeved with a limit disk, and the top side of the storage container is in contact with the bottom side of the limit disk. A plurality of pressure sensors are arranged in a circumferential array on the outer peripheral side of the bottom of the conduit, and both ends of each pressure sensor are fixedly connected to the limit disk and the inner wall of the constant temperature chamber respectively.

[0008] Preferably, a sealing ring is fixedly installed in the limit disk, and the inner ring wall of the sealing ring is in contact with the outer peripheral wall of the conduit.

[0009] Preferably, an annular groove is formed on the top side of the storage container, a sealing ring is arranged in the annular groove, and the outer wall of the sealing ring is in interference fit with the inner wall of the annular groove. The top side of the sealing ring extends outside the annular groove and is in contact with the bottom side of the limit disk.

[0010] Preferably, a limit ring is fixedly sleeved on the bottom end of the conduit, and the top side of the limit ring is in clearance fit with the bottom side of the limit disk.

[0011] Preferably, the diversion mechanism includes a plurality of one-way valves. A diversion groove is formed in the barrel wall of the storage container.

[0015] 1. When the odor scanner for aromatherapy detection is in use, the operator fits the storage container containing the aromatherapy sample on the limit disk, so that the storage container can be automatically adsorbed and fixed on the limit disk through the negative pressure cavity formed in the storage container. The operation of the device is simple. Then, the amount of the aromatherapy sample is detected by the pressure sensor, and then the odor of the aromatherapy is detected by the odor scanner, avoiding the influence of the escape of the aromatherapy on the accuracy of the aromatherapy detection structure;

[0016] 2. When performing the aromatherapy smell detection as described above, since a relatively enclosed cavity is formed inside the storage container, and the gas in the constant temperature chamber continuously flows into the storage container, it can prevent the aromatherapy sample in the storage container from vaporizing and escaping.

[0023] In order to make the technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] The present invention provides a technical solution: Referring to Figure 1 - Figure 5 , an odor scanner applicable to aromatherapy detection disclosed by the present invention includes a constant temperature chamber 1 and an odor scanner body 2. The odor scanner body 2 is fixedly installed on the top side of the constant temperature chamber 1. A connection mechanism 3 is provided at the air inlet end of the odor scanner body 2. A storage container 5 is provided in the constant temperature chamber 1, and a diversion mechanism 4 is provided in the storage container 5;

[0025] The connecting mechanism 3 includes an air pump 31, which is fixedly installed on the top side of the constant temperature chamber 1. The exhaust end of the air pump 31 is connected and installed with the intake end of the odor scanner body 2. The intake end of the air pump 31 is connected and installed with a conduit 32. The bottom end of the conduit 32 extends into the constant temperature chamber 1 and is fixedly connected to the outer shell of the constant temperature chamber 1. A limiting disk 33 is slidably sleeved on the outer peripheral side of the bottom end of the conduit 32. The top side of the storage container 5 is in contact with the bottom side of the limiting disk 33. A plurality of pressure sensors 34 are arranged in a circumferential array on the outer peripheral side of the bottom of the conduit 32. Both ends of each pressure sensor 34 are fixedly connected to the limiting disk 33 and the inner wall of the constant temperature chamber 1 respectively.

[0026] In this embodiment, when the improved odor scanner for aromatherapy detection is in use, the operator first opens the hatch in the constant temperature chamber 1 and takes out the storage container 5 in the constant temperature chamber 1. Then, an appropriate amount of aromatherapy sample is poured into the storage container 5, and the hatch of the constant temperature chamber 1 is opened and the storage container 5 is placed into the constant temperature chamber 1. Then, the top end of the storage container 5 is attached to the limiting disk 33. Subsequently, the operator starts the pneumatic pump. The air pump 31 continuously extracts the gas in the storage container 5 through the conduit 32. Since the amount of the constant temperature gas flowing into the storage container 5 from the outer peripheral side of the storage container 5 is limited, a negative pressure chamber is continuously formed in the storage container 5. Finally, the storage container 5 is adsorbed and fixed on the limiting disk 33 through the negative pressure chamber in the storage container 5.

[0027] During the process of adsorbing and fixing the storage container 5 on the limiting disk 33 as described above, the air flow passes through the aromatherapy sample in the storage container 5, enabling the gas to fully contact the aromatherapy sample, thereby accelerating the evaporation rate of the aromatherapy sample, simulating the treatment operation of inserting an activated carbon rod into the aromatherapy to accelerate the evaporation of the aromatherapy, and simulating the temperature environment of each season through the constant temperature chamber 1, so that the air flow is mixed with the vaporized aromatherapy sample. Subsequently, the air flow carries the vaporized aromatherapy sample into the odor scanner body 2 for detecting the odor of the aromatherapy sample, thereby determining whether the odor of the aromatherapy sample is qualified.

[0028] After the storage container 5 is fixed as described above, the operator closes the hatch of the constant temperature chamber 1 and starts the pressure sensor 34. The pressure sensor 34 detects the weights of the aromatherapy sample, the storage container 5 and the limiting disk 33, thereby automatically obtaining the amount of the aromatherapy sample. According to the above, when the odor scanner detects that there is no fragrance in the gas, the maximum usage duration of a unit of aromatherapy is obtained.

[0029] After the detection of the aromatherapy sample is completed, the air pump 31 runs for a period of time, so that the air flow can be used to clean the inside of the conduit 32 and the air passage of the odor scanner body 2, thereby preventing the residual aromatherapy in the conduit 32 and the air passage of the odor scanner body 2 from affecting the subsequent detection of the aromatherapy sample.

[0030] In a further preferred embodiment of the present utility model, as Figure 3 andFigure 4 As shown, a sealing ring 35 is fixedly installed inside the limit disc 33, and the inner ring wall of the sealing ring 35 is in contact with the outer peripheral wall of the conduit 32;

[0031] In this embodiment, the setting of the sealing ring 35 can block the gap between the conduit 32 and the limit disc 33, making the adsorption and fixation between the storage container 5 and the limit disc 33 more stable.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 5 shown, an annular groove 36 is formed in the top side of the storage container 5, a sealing ring 37 is arranged in the annular groove 36, and the outer wall of the sealing ring 37 is in interference fit with the inner wall of the annular groove 36. The top side of the sealing ring 37 extends outside the annular groove 36 and is in contact with the bottom side of the limit disc 33;

[0033] In this embodiment, when the storage container 5 and the limit disc 33 are adsorbed and fixed, due to the mutual resistance between the limit disc 33 and the sealing ring 37, the sealing ring 37 deforms adaptively according to the contact position of the limit disc 33 within the annular groove 36, thereby automatically blocking the gap between the storage container 5 and the limit disc 33, making the adsorption and fixation between the storage container 5 and the limit disc 33 more stable.

[0034] In a further preferred embodiment of the present utility model, as Figure 4 shown, a limit ring 38 is fixedly sleeved on the bottom end of the conduit 32, and the top side of the limit ring 38 is in clearance fit with the bottom side of the limit disc 33;

[0035] In this embodiment, the setting of the limit ring 38 can restrict and limit the downward movement length of the limit disc 33, preventing the pressure sensor 34 from being damaged due to excessive downward movement distance of the limit disc 33.

[0036] In a further preferred embodiment of the present utility model, as Figure 5 shown, the diversion mechanism 4 includes a plurality of one-way valves 42. A diversion groove 41 is formed in the barrel wall of the storage container 5. The plurality of one-way valves 42 are arranged in a circumferential array on the inner bottom side of the storage container 5, and the air inlet end of each one-way valve 42 is inserted into the diversion groove 41 and fixedly connected to the barrel wall of the storage container 5. A plurality of air inlet holes 43 are formed in the outer peripheral wall of the storage container 5, and the interior of each air inlet hole 43 is communicated with the interior of the diversion groove 41;

[0037] In this embodiment, after the negative pressure chamber is formed in the storage container 5, due to the pressure difference at both ends of the one-way valve 42, the gas in the diversion groove 41 continuously flows into the storage container 5 through the one-way valve 42, and a negative pressure chamber is continuously formed in the diversion groove 41. Furthermore, a pressure difference is formed at both ends of the air inlet hole 43, and the constant-temperature gas in the constant-temperature chamber 1 continuously flows into the diversion groove 41 through the air inlet hole 43 to supplement the gas lost in the diversion groove 41, so that while the gas enters from the bottom of the storage container 5, the aromatherapy sample in the storage container 5 is prevented from flowing out of the storage container 5.

[0038] In a further preferred embodiment of the present utility model, as Figure 5 shown, a plurality of air inlet holes 43 are arranged in a circumferential array on the outer peripheral wall of the top of the storage container 5, and the diversion groove 41 is arranged in a cylindrical shape;

[0039] In this embodiment, when the constant-temperature gas in the constant-temperature chamber 1 flows through the air inlet hole 43 towards the one-way valve 42, the constant-temperature gas closely adheres to the inner wall of the diversion groove 41, so that the storage container 5 is always maintained at a specific temperature to stabilize the environment around the aromatherapy sample.

[0040] In a further preferred embodiment of the present utility model, as Figure 5 shown, a plurality of mesh plates 44 are provided above a plurality of one-way valves 42, and the outer peripheral wall of each mesh plate 44 is fixedly connected to the inner wall of the storage container 5, and the distance between adjacent two mesh plates 44 is equal;

[0041] In this embodiment, when the gas flowing into the aromatherapy sample from the one-way valve 42 travels inside the aromatherapy sample, due to the blocking of the mesh plate 44, the air flow is split into several small air flows that pass through the holes of the mesh plate 44. Furthermore, the several small air flows travel inside the aromatherapy sample, so that the gas is in full contact with the aromatherapy sample, thereby accelerating the evaporation rate of the aromatherapy sample, simulating the treatment operation of inserting an activated carbon rod into the aromatherapy to accelerate the evaporation of the aromatherapy, and reducing the consumption of supplies during aromatherapy detection.

[0042] Working principle: When the odor scanner for aromatherapy detection is in use, the operator first opens the hatch in the constant-temperature chamber 1 and takes out the storage container 5 in the constant-temperature chamber 1, then pours an appropriate amount of aromatherapy sample into the storage container 5, opens the hatch of the constant-temperature chamber 1 and puts the storage container 5 into the constant-temperature chamber 1, then fits the top end of the storage container 5 on the limit disk 33. Subsequently, the operator starts the pneumatic pump, and the air pump 31 continuously extracts the gas in the storage container 5 through the conduit 32. Since the amount of gas flowing into the storage container 5 through the connection hole, the diversion groove 41 and the one-way valve 42 on the outer peripheral side of the storage container 5 is limited, a negative pressure chamber is continuously formed in the storage container 5, and finally the storage container 5 is adsorbed and fixed on the limit disk 33 through the negative pressure chamber in the storage container 5;

[0043] During the above process of adsorbing and fixing the storage container 5 on the limit plate 33, the gas flowing into the aromatherapy sample from the one-way valve 42 is blocked by the mesh plate 44 during its passage through the aromatherapy sample. As a result, the air flow is split into several small air flows that pass through the holes of the mesh plate 44, and then the several small air flows pass through the aromatherapy sample, enabling the gas to come into full contact with the aromatherapy sample, thereby accelerating the evaporation rate of the aromatherapy sample and simulating the treatment operation of inserting an activated carbon rod into the aromatherapy to accelerate evaporation. Thus, the gasified aromatherapy sample is mixed in the air flow, and then the air flow carries the gasified aromatherapy sample into the odor scanner body 2 for detecting the odor of the aromatherapy sample, so as to determine whether the odor of the aromatherapy sample is qualified;

[0044] After the above fixing of the storage container 5 is completed, the operator closes the door of the constant temperature chamber 1 and activates the pressure sensor 34. The pressure sensor 34 detects the weights of the aromatherapy sample, the storage container 5 and the limit plate 33, thereby automatically obtaining the amount of the aromatherapy sample. According to the above, when the odor scanner detects that there is no fragrance in the gas, the maximum usage duration of a single aromatherapy can be obtained;

[0045] It should be noted that when the constant temperature gas in the constant temperature chamber 1 flows through the air inlet hole 43 towards the one-way valve 42, the constant temperature gas is in close contact with the inner wall of the diversion groove 41, so that the storage container 5 is always maintained at a specific temperature, and the temperature in the constant temperature chamber 1 is adjusted by the constant temperature chamber 1, so as to simulate the usage conditions of the aromatherapy in different seasons.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
