Description

Technical Field

[0001] The invention relates to the technical field of olfactory screening, training, assessment and odor evaluation, and in particular to a handheld odor quantitative release device. Background Art

[0002] At present, the evaluation of odor pollution is mainly based on the corresponding standards and is achieved through olfactory sensory tests of odorists. The screening, training and assessment of odorists, as well as the grading of odor intensity, all require a standard odor source. In most standards, the odor standard source adopts the test paper method, which is to immerse odorless paper in odorous liquid and then take it out and give it to the odorist to smell. The disadvantage of this method is that each test requires manual dipping of odorous liquid, and the consistency of the test paper invasion time, invasion depth, and test paper transfer time cannot be guaranteed. There are large errors in the test results. In addition, the test efficiency is low because it requires manual dipping of odorous liquid. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a handheld odor quantitative release device, which can not only continuously and stably release odor substances, but also does not require human interference in the odor release process, greatly reducing the test error, improving the accuracy of the test, and greatly improving the efficiency of the test.

[0004] The present invention provides a handheld quantitative odor release device, comprising: a shell, provided with a accommodating chamber; a partition, the partition is arranged in the accommodating chamber and cooperates with the inner wall surface of the shell to separate the accommodating chamber into an air source storage chamber and an odor release chamber, wherein the air source storage chamber is used to store a liquid odor source; an odor release component, comprising a sleeve and a core body arranged in the sleeve, one end of the sleeve is arranged in the air source storage chamber, and the other end is arranged in the odor release chamber, and the other end of the sleeve is provided with an odor release hole, and the core body is suitable for absorbing the liquid odor source and releasing the odor through the odor release hole.

[0005] The handheld odor quantitative release device provided by the present invention divides the accommodating chamber of the shell into an air source storage chamber and an odor release chamber by arranging a partition in the shell, and one end of the sleeve is arranged in the air source storage chamber, and the other end is arranged in the odor release chamber. A core body is arranged in the sleeve, and the core body can absorb a liquid odor source. One end of the sleeve arranged in the odor release chamber is provided with an odor release hole, so that after the core body absorbs the liquid odor source, the odor can be released from the odor release hole, thereby solving the technical problem in the prior art that a test paper needs to be dipped in odor liquid and then taken out for odor identification by an odorist. In addition, since the odor substance can be released continuously and stably, human interference is avoided in the odor release process, which effectively improves the accuracy of the test and greatly improves the efficiency of the test.

[0006] It is worth noting that, since the apertures of the odor release holes are different, the amount of odor released per unit time is different, so the test of odor intensity can be tested by multiple handheld odor quantitative release devices, and the multiple handheld odor quantitative release devices have odor release holes with different apertures. For example, taking n-butanol as the odor source, 5 mL of n-butanol is added to five handheld odor quantitative release devices respectively, and the apertures of the odor diffusion holes of the five handheld odor quantitative release devices are set to 0.1 mm, 0.6 mm, 1 mm, 2 mm and 5 mm respectively, and the corresponding odor intensities are level 1, level 2, level 3, level 4 and level 5 respectively, which are used as the reference benchmark for odor evaluation.

[0007] According to one embodiment of the present invention, the odor release component also includes: a fixed seat, which is arranged in the gas source storage chamber and connected to the bottom wall of the shell; an odor diffusion pool, which is arranged at the other end of the sleeve, and the odor diffusion hole is provided on the odor diffusion pool, and the liquid odor source absorbed by the core is suitable for volatilization and release from the odor release hole; wherein the fixed seat is provided with a limiting groove, the limiting groove is communicated with the gas source storage chamber, and one end of the sleeve is arranged in the limiting groove.

[0008] The odor release component also includes a fixed seat and an odor diffusion pool. The fixed seat is arranged in the gas source storage chamber and fixedly connected to the bottom wall of the shell, and the fixed seat is provided with a limiting groove, which is connected to the gas source storage chamber. One end of the sleeve is arranged in the limiting groove, so that the liquid odor source can enter the sleeve, thereby realizing that the liquid odor source can soak the core. The odor diffusion pool is arranged at the other end of the sleeve (that is, arranged at the end of the sleeve located in the odor release chamber), and the liquid odor source can volatilize in the odor diffusion pool. The odor diffusion hole is arranged on the odor diffusion pool, so that the liquid odor source can be absorbed by the core and then volatilize and diffuse in the odor diffusion pool, and then released from the odor diffusion hole, thereby improving the timeliness of odor release and the accuracy of the test.

[0009] According to one embodiment of the present invention, one end of the sleeve is tightly connected to the limiting groove; and / or the odor diffusion pool is detachably connected to the other end of the sleeve; and / or the odor diffusion pool is provided with a plug, which covers the odor diffusion hole, and the plug is suitable for rotating relative to the odor diffusion pool to change the size of the odor diffusion hole.

[0010] The size of the limiting groove is adapted to one end of the sleeve (i.e., one end of the gas source storage chamber), and one end of the sleeve is tightly connected with the limiting groove, without the need to add other connecting parts, reducing the parts of the product, thereby reducing the production cost of the product and facilitating installation and disassembly. At the same time, when the sleeve is tightly connected with the fixing seat, the connection is more reliable, thereby improving the stability of the sleeve installation.

[0011] The odor diffusion pool is detachably connected to the other end of the sleeve (i.e., one end of the odor release chamber) to facilitate the maintenance and replacement of the odor diffusion pool, and the odor release holes of different apertures can be changed by replacing odor diffusion pools of different specifications.

[0012] A stopcock is provided on the odor diffusion pool, which covers the odor diffusion hole to seal and prevent the odor from volatilizing and wasting. The stopcock can rotate relative to the odor diffusion pool to adjust the size of the odor diffusion hole, thereby achieving testing of different odor intensities.

[0013] According to one embodiment of the present invention, the fixing seat is provided with a first connecting hole, which connects the limiting groove and the gas source storage chamber; or, the fixing seat is provided with a connecting pipe, which is respectively connected to the limiting groove and the gas source storage chamber.

[0014] By providing a first connecting hole on the fixing seat, the first connecting hole can be set on one side of the bottom of the fixing seat, so that the limiting groove is connected with the gas source storage chamber, so that the liquid odor source can enter the limiting groove and the sleeve. After the liquid odor source soaks the core body and reaches the top of the core body, it evaporates from liquid to gas in the diffusion pool, and the gaseous odor substance is released from the odor diffusion hole to the odorist for odor identification, and the release amount of the odor substance is controlled by the size of the odor diffusion hole to obtain a reference benchmark for different odor intensities.

[0015] By arranging a connecting pipe on one side of the bottom of the fixing seat, the connecting pipe is connected to the limiting groove and the gas source storage chamber respectively, so that the liquid odor source can enter the interior of the sleeve through the connecting pipe. The structure and principle are relatively simple and easy to implement.

[0016] According to one embodiment of the present invention, the partition comprises a partition, the partition is sealedly connected to the inner wall surface of the shell, and a second connecting hole is provided on the partition, the second connecting hole is adapted to the sleeve, and the sleeve is passed through the second connecting hole.

[0017] The partition includes a partition sealedly connected to the inner wall surface of the shell (such as welding). By arranging a second connecting hole on the partition, one end of the sleeve can be located in the gas source storage chamber and the other end can be located in the odor release chamber. At the same time, the storage and odor release of the liquid odor source can be realized in different chambers respectively.

[0018] According to another embodiment of the present invention, the handheld quantitative odor release device further includes: a sealing member, which is arranged on the inner circumference of the second communicating hole, the sleeve is passed through the second communicating hole, and the sealing member is elastically deformed to seal the second communicating hole.

[0019] The handheld quantitative odor release device also includes a seal (such as a sealing ring or a sealing gasket) arranged on the inner circumferential side of the second connecting hole. The seal serves to seal the second connecting hole to prevent the liquid odor source in the gas source storage chamber from leaking from the second connecting hole, thereby improving the safety of product use.

[0020] In some embodiments, the shell is provided with an odor release port, and the odor release port is arranged corresponding to the odor release hole.

[0021] The shell is provided with an odor release port, which is located at the same end of the shell as the odor release hole. The odor is released through the odor release hole and released to the outside of the shell through the odor release port to facilitate odor identification by the odorist.

[0022] In some embodiments, the handheld quantitative odor release device further includes: a sealing cover, wherein the sealing cover is disposed on the odor release port.

[0023] The handheld quantitative odor release device also includes a sealing cover arranged on the odor release port, which seals the odor release port to prevent odor from leaking from the odor release port to the outside of the shell, thereby further improving the safety of product use.

[0024] According to one embodiment of the present invention, one end of the shell provided with the odor release port is provided with a stopper, and the sealing cover is provided with a stopper matching portion, and the stopper matching portion cooperates with the stopper matching portion to limit the relative position of the sealing cover and the shell.

[0025] By arranging a stopper at one end of the shell body provided with the odor release port, and arranging a stopper matching portion on the sealing cover, the stopper matches with the stopper matching portion, thereby limiting the position of the sealing cover on the shell body when the sealing cover is arranged on the odor release port, thereby improving the convenience of using the sealing cover.

[0026] According to one embodiment of the present invention, the stop portion includes a first groove formed by a local depression of the outer peripheral wall of the shell, the stop fitting portion includes a second groove formed by a local depression of the inner peripheral wall of the sealing cover, the sealing cover is arranged on the odor release port, the sealing cover abuts against the first groove, and the shell abuts against the second groove; or, the stop portion includes a first groove formed by a local depression of the inner peripheral wall of the shell, the stop fitting portion includes a second groove formed by a local depression of the outer peripheral wall of the sealing cover, the sealing cover is arranged on the odor release port, the sealing cover abuts against the first groove, and the shell abuts against the second groove.

[0027] By setting a first groove on the outer circumferential wall of the shell and a corresponding second groove on the inner circumferential wall of the sealing cover, when the sealing cover is placed on the odor release port, the sealing cover can abut against the groove wall of the first groove, and at the same time, the upper end of the shell can abut against the groove wall of the second groove, thereby limiting the relative position of the sealing cover and the shell.

[0028] On the contrary, a first groove is provided on the inner wall of the shell, and a second groove corresponding to the first groove is provided on the outer wall of the sealing cover, so that the relative position of the sealing cover and the shell can be limited when the sealing cover is placed on the odor release port, and at the same time, it also helps to improve the aesthetics of the product.

[0029] Of course, an internal thread may be provided on the inner circumference of the sealing cover, and an external thread may be provided on the outer circumference of the shell, so that the sealing cover and the shell are connected in a threaded connection manner to achieve a sealing effect.

[0030] In some embodiments, the handheld scent release device is cylindrical in shape as a whole, which is convenient for holding and carrying.

[0031] The handheld odor quantitative release device provided by the present invention can not only release odor substances continuously and stably, but also the odor release process does not require human interference, which greatly reduces the test error, improves the test accuracy, and greatly improves the test efficiency.

A core 302 is arranged in the sleeve 301, and the core 302 can absorb a liquid odor source. One end of the sleeve 301 arranged in the odor release chamber 102 is provided with an odor release hole 303, so that after the core 302 absorbs the liquid odor source, the odor can be released from the odor release hole 303, which solves the technical problem in the prior art that it is necessary to use a test paper to dip in the odor liquid and then take it out for the odorist to smell it. In addition, since the odor substance can be released continuously and stably, human interference is avoided during the odor release process, which effectively improves the accuracy of the test and greatly improves the efficiency of the test.

[0043] It is worth noting that, since the apertures of the odor release holes 303 are different, the odor release amounts per unit time are different, so the test of odor intensity can be conducted through multiple handheld odor quantitative release devices 1, and the multiple handheld odor quantitative release devices 1 have odor release holes 303 with different apertures. For example, taking n-butanol as the odor source, 5 mL of n-butanol is added to five handheld odor quantitative release devices 1, and the apertures of the odor diffusion holes of the five handheld odor quantitative release devices 1 are set to 0.1 mm, 0.6 mm, 1 mm, 2 mm and 5 mm, respectively, and the corresponding odor intensities are level 1, level 2, level 3, level 4 and level 5, respectively, which are used as reference benchmarks for odor evaluation.
