Fig. 1 shows the outside schematic diagram of smell release device according to an embodiment of the invention.Correspondingly, Fig. 2 shows The explosive view of all parts according to an embodiment of the invention for constituting smell release device is gone out.

Smell release device 10 mainly includes shell 12, which includes opening 16, and be open 16 Inner Constitution chambers.It should Chamber can be used for accommodating replaceable core 20, and be open 16 for replaceable core 20 discharge olfactorin.As shown, shell 12 Elongated shape can be presented, for example, can have cylindrical outer surface 18.The global shape of the device 10 can be similar with appearance In lettering pen and it is constructed and arranged suitable for grasping and hand-held being operated.There is the lid for covering opening in device 10 When (for example, lid 50), lid 50 may include clamp structure 52 to prevent from tumbling.In other embodiments, it rolls in order to prevent It falls, shell 12 and/or lid 50 can be configured to polygonal cross section (for example, hexagon).There is elongated shape in shell 12 In the case where shape (preferably lip pencil), for the convenience of description, the length direction of shell is considered as axial direction, cross-wise direction is considered as diameter To in the axial direction, it is rear portion far from olfactorin liberation port that the opening portion of close olfactorin liberation port, which is front,.It should be understood that It is that shell 12 also can have elongated shape or write the other shapes except lip pencil, as long as it is convenient for hand-held.

Replaceable core 20 is alternatively mounted in the chamber of shell 12.Liquid olfactorin is accommodated in core 20 22, and core 20 includes the olfactorin liberation port 24 for discharging olfactorin.Here, " replaceable " refers to core 20 not by not It is removably mounted in shell 12, but olfactorin uses the feelings for finishing or need to be packed into other cores in such as core 20 It can be replaced under condition.Preferably, every replaceable core 20 can be used for multiple smell presentation.

In the present invention, olfactorin liberation port 24 carries out olfactorin release under external force.More specifically, being 10 single of device When using (for example, for certain primary Olfactometry or smell training), applied on the device 10 by the people of operating device 10 External force, so that olfactorin liberation port 24 carries out olfactorin release.Due to olfactorin be this using when discharged on the spot, smell Element is not allowed perishable, and can be used in accurate smell and (for example, threshold measurement) is presented.In addition, due to the release of olfactorin be by (for example, being controlled by operator) of external force control, therefore the release capacity of olfactorin is generally also controllable.

External force can act directly on olfactorin relieving mechanism, for so that replaceable core 20 is acting on olfactorin release Olfactorin 22 is discharged via olfactorin liberation port 24 under the external force of mechanism.In an embodiment of the present invention, olfactorin relieving mechanism can be It is shown in figure (as shown in Figures 2 and 3), it, can also be with as the pushing mechanism 30 of the separate part except shell 12 and core 20 It is the pushing mechanism stretched out on core 20, it might even be possible to be shell 12 itself.As follows by a variety of realizations to olfactorin relieving mechanism It is described in detail.

Fig. 3 shows the specific configuration example of replaceable core according to an embodiment of the invention.In one embodiment, Replaceable core 20 can have piston construction, such as the construction of syringe-like shown in figure.Above-mentioned construction can be with example The pushing mechanism 30 as olfactorin relieving mechanism as shown in Figure 4 cooperates, to realize the accurate of olfactorin under external force Release.Fig. 4 shows the specific configuration example of pushing mechanism according to an embodiment of the invention.

In the case where using pushing mechanism 30 as the olfactorin relieving mechanism being stressed directly, operator, which is applied directly to, to be pushed away External force on motivation structure 30 can be conducted to replaceable core 20, thus push piston core pin 26, and lead to replaceable core 20 The middle space interior pressure rise for accommodating olfactorin 22, so that olfactorin 22 is discharged via olfactorin liberation port 24.

In order to easy to operate, and guarantee the structural intergrity of device 10, pushing mechanism 30 can be used as rear simultaneously End cap.In the case where device 10 has the shape of similar lettering pen, pushing mechanism 30 may be used as tail end cap.Preferably, Pushing mechanism 30 or its at least part are solid each other with shell 12 when device 10 is equipped with replaceable core 20 and normal use It is fixed or fixed in (for example, axial) at least in one direction.Above-mentioned fixation for example can screw or be clamped via screw thread real It is existing.Since pushing mechanism 30 needs to push 26 propulsion of piston core pin, at least part is needed in force and shell Body 12 keeps relative motion (even if in the case where part of it and fixed shell 12).

In one embodiment, pushing mechanism can be different from the example of Fig. 4 and have pressing member, so that operator makees It can be conducted directly down to piston core pin 26 for depressing the power on the axial direction of component, so that 26 direction of piston core pin Anterior movements and the release for pushing liquid olfactorin.In the embodiment as shown in fig.4, pushing mechanism 30 can have radial motion Rotary part 32, thus convert radial force to via screw thread the lower pressure of piston core pin 26.For this purpose, pushing mechanism 30 and can Replacement core 20 can have the linkage structure for the movement that is fitted to each other after replaceable core 20 is installed in place in shell 12.? In one embodiment, which is embodied as the card that pushing mechanism 30 and replaceable core 20 are arranged on shell axial direction Binding structure.Fig. 3 and Fig. 4 respectively illustrates the axial notch 29 and 39 being fitted to each other on core 20 and pushing mechanism 30, is installing In the case where in place, core 20 is connected in pushing mechanism 30, thus in the tail end of operator's radial rotary pushing mechanism, on Stating rotary force can push part 28 to be converted into the lower pressure to piston core pin 26 via the screw thread of core 20 shown in Fig. 3, by This leads to the release of olfactorin.

Fig. 3 and the external force conversion scheme shown in Fig. 4 via screw thread due to can the burst size to olfactorin accurately controlled, It is particularly suitable for needing the case where accurate odorousness is presented (for example, threshold testing).Further, compared to directly pushing Conduction regime, above-mentioned threaded arrangement are easier to avoid maloperation (for example, in transport and storage since olfactorin caused by squeezing misses Discharge), and make core more safe to the preservation of olfactorin.In addition, the rotary part 32 of pushing mechanism 30 can also be such as Fig. 4 It is shown that there is textured outer surface, to facilitate stress.

Different from the pushing mechanism in precedent, power can also be directly acted on replaceable core by operator, and directly logical The internal structure for crossing core realizes olfactorin release.For example, replaceable core may include the stretching structure stretched out from shell.It should Stretching structure directly connect with the intracorporal piston core pin of replaceable core and can be under the effect of external force on the axial direction of shell It is mobile.

In different realizations, above-mentioned stretching structure can according to need from the tail end of shell (for example, thin-long casing) or Side is stretched out.For example, the rear end of shell can there are the opening that the stretching structure for core is stretched out, and cores as shown in Figure 3 Tail end (or its variant) can directly stretch out, operator by the above-mentioned tail end of radial rotary, through before thread mechanism to pushing piston Core bar is to discharge olfactorin.Replaceable core also can have pressing structure, and above-mentioned pressing structure is stretched out from shell, and operator can be with Push piston core pin to discharge olfactorin by directly pushing.Since the tail end of replaceable core at this time can be living relative to shell It is dynamic, thus the front of core preferably can as shown in figs. 2 and 7 via written 40 (or other front end connecting components) and with shell Front end is fixed.Preferably, nib 40 can have the helicitic texture to match with housing forward end, to prevent core itself relative to shell The propulsion of body.In other implementations, shell can have the astomous structure in tail portion, while can have such as edge in side Axially extending narrow slit, replaceable core extend laterally structure and can stretch out from the seam.Operator can push down on or The stretching structure is stirred, thus forward direction pushes piston core pin to discharge olfactorin.

In some embodiments, hand-held smell release device of the invention can also have more similar to lettering pen Construction.For example, olfactorin liberation port may be constructed such that the structure of similar ball pen, water-color paintbrush, watercolor pencil or Pen nib or pen core It makes, thus thin-long casing itself may be used as olfactorin relieving mechanism.That is, holding shell in such as blotting paper in operator Plane on carry out write shape operation, or by olfactorin liberation port other modes against certain an object (for example, water imbibition material Material) when, such as ball construction (be similar to ballpoint tip) of olfactorin liberation port, biplate construction (being similar to Pen nib) or Olfactorin is discharged under stress similar to the pen core construction of watercolor pencil, for example, flowing to olfactorin on blotting paper.

It should be understood that olfactorin release device can also have other realizations except example as described above, as long as its The external force from operator being directly subject to can be transferred to replaceable core, so that olfactorin liberation port is based on suffered pressure Power carries out corresponding olfactorin release.

In the illustrated embodiment, the olfactorin liberation port of replaceable core is preferably olfactorin relief hole 24.Olfactorin is discharged Mouth is made poroid, facilitates the olfactorin burst size being accurately controlled under pressure, can be to avoid the olfactorin of storage and the big face of air Product contact, it is also convenient when not in use to the closing of liberation port.Here, " release " is preferred to refer to " discharge ", that is, by olfactorin itself It is expelled to outside core (for example, in smell presentation device described below) from core, rather than only discharges what olfactorin distributed Smell.In other words, object (for example, subject or trainee) institute smelling of the above-mentioned release olfactorin of smelling is not that this is smelt Plain liberation port itself, but the object (the preferably disposable object of single smelling) of above-mentioned discharge olfactorin is carried or absorbs, Thus, it is possible to avoid pollution of the breath of subject or trainee to smell release device.

Correspondingly with above-mentioned relief hole, replaceable core 20 includes outwardly directed needle tubing 23, and olfactorin relief hole 24 In the distal end of needle tubing 23 or the side mouth of nearly distal end.The olfactorin relief hole 24 in needle tubing side opening is shown in detail in Fig. 3 Example.The needle tubing of elongated stretching can further avoid the olfactorin of the interior storage of core and coming into contact in a large area for air, reduce or keep away Exempt from olfactorin discharge in the non-use state.Side mouth then facilitates in the non-use state to the obstruction of relief hole, also facilitates Such as absorption or carrying (described below) of the smell presentation device to discharge olfactorin.

Preferably, smell release device of the invention further includes that olfactorin liberation port is avoided to be exposed to outer structure.

In one embodiment, olfactorin liberation port can be closed using choke structure when discharging without olfactorin.Example Such as, individual plug (for example, polypropylene PP covers) can be used to close olfactorin relief hole.Preferably, above-mentioned choke structure can It can be carried out with smell release device in the structure of overall package with being located at.As depicted in figs. 1 and 2, smell of the invention release Device 10 may further include the lid 50 similar to pen cover.As described above, lid 50 can close the opening 16 of shell 12, The olfactorin liberation port 24 of olfactorin is stretched out from opening 16 or is discharged via opening 16 in closing simultaneously.When Fig. 7 is shown on cover cap The cooperation schematic diagram of choke structure and olfactorin relief hole.As shown in fig. 7, choke structure 62 (for example, PP covers) can be arranged in lid In body 50, it is preferably arranged in the lid liner 60 of lid 50.When lid 50 is clamped (for example, covering tightly) on housing 12 (that is, when device 10 is in non-working condition), the end of needle tubing 23 can just be protruded into the choke structure 62 of lid 50.By This, such as realize that the liberation port 24 to the last end or proximal end of needle tubing 23 side is closed using PP material, it is ellipse in Fig. 7 to be formed The enclosed construction A that ring is indicated.In the preferred embodiment as shown in the explosive view of Fig. 2, choke structure 62 can be located at lid In vivo in lining 60, or as a part of lid liner 60, the lid liner 60 itself can be by blocking material, such as PP material It is made, and is disposed in lid 50 for example made of metal.

Above-mentioned choke structure can also be combined with the lid (for example, needle tubing lid) of liberation port, to be open as to covering 16 itself lid 50 or its inner lining structure replacement or supplement.

In another embodiment, smell release device 10 can take in olfactorin liberation port when discharging without olfactorin The intracorporal recovery structure of elongated shell.For example, smell release device 10 can tail portion be arranged be connect with spring it is lower by structure (scheme In be not shown), to realize the stretching and retraction of olfactorin liberation port.The lower structure of pressing can also link with closure of openings structure, example Such as, press under this by structure, the opening of shell is opened and liberation port stretches out, pressed again by structure under this, liberation port retract and The opening of shell is closed.

As described above, smell release device 10 of the invention is release olfactorin controlled under external force, that is, operator Single motion the intracorporal whole olfactorins of core can not usually be discharged.It is therefore preferred that using smell release device of the invention, The olfactorin amount of each operation release can also be controlled.For this purpose, smell release device may include for discharging or indicating Discharge the capacity limiting structure of the olfactorin of specified vol.

In one embodiment, the intracorporal olfactorin of core is the lasting and controlled discharge under the ongoing operation of operator.Cause This, can be come by informing that operator currently discharges whether released the desired amount of olfactorin (for example, capacity instruction structure) Instruct the operation of operator.Here, capacity limiting structure is to be used to indicate the instruction structure for releasing how many capacity olfactorins, example Such as, scale.Specifically, above-mentioned capacity instruction structure may include that can show the structure of olfactorin current capacities, for example, for showing Show the transparent or semitransparent shell of the replaceable core of remaining olfactorin capacity, and the shell for showing remaining olfactorin capacity Instruction opening or transparent or semitransparent housing parts.Further, transparent or semi-transparent on replaceable core or shell Scale is indicated on bright shell.Fig. 5 shows the specific configuration example of shell according to an embodiment of the invention.In the example of Fig. 5 In, shell itself can be made of non-transparent material, for example, metal shell, but be provided on the outer surface 18 of shell 12 axially extending Elongated slot, be mounted with to mark graduated transparent or semitransparent material in slot, thus formed on shell and be directed to replaceable core 20 The indicating arrangement 14 of interior residue olfactorin amount.In other embodiments, it also can be used transparent shell made of such as plastics, and Side reference numerals.Above-mentioned scale can number 1-5 shown in figure, corresponding to the amount for needing to discharge every time in five uses； It is also possible to more intensive or sparse scale, to adapt to discharge the demand of identical or different amount olfactorin every time.Due to can be through There remains how many olfactorin out of external observation core by transparent or semitransparent core and shell, and can be remained by scale The accurate instruction of surplus, therefore operator can be continuously applied external force (for example, the rotary part of continuous rotation pushing mechanism 30 32) to discharge olfactorin 22, until remaining olfactorin reaches predetermined graduated line.

Alternatively, or in addition, the quantitative release to olfactorin can also be realized using other mechanism.Implement at one In example, smell release device of the invention can also include the capacity limiting structure for discharging the olfactorin of specified vol, the knot Structure can for example be realized by the olfactorin relieving mechanism that can quantitatively discharge olfactorin.Pushing mechanism or stretching structure for example can have response In the mechanical structure of each operation release specific quantity olfactorin of user.

In certain embodiments, the olfactorin amount that each smell discharges required discharge in operation can be identical.Such as Fig. 5 institute Show, the olfactorin of a scale institute limited amount can be discharged every time, is discharged with smell needed for smelling of satisfaction.In other implementations In example, olfactorin relieving mechanism can discharge different amounts of olfactorin in single smell training or olfactometry to meet various concentration Smell present require.Smell presentation can for example be matched with following smell presentation devices, to realize the need of various concentration It asks.

As described above, smell release of the invention is preferably based on olfactorin and realizes from olfactorin liberation port " discharge ".Therefore, exist It, can be by olfactorin " discharge " to any object, for example, olfactorin is discharged to common paper handkerchief, very in wider embodiment To being dropped on desktop or floor, as long as facilitating smelling.But it for working specification, releases odorousness control, avoid smelling Element pollution is contaminated or be that (primary complete smell training and test usually require smelling for taint of odour between preventing different olfactorins A variety of smells) needs, be preferably provided with a kind of can present with the smell that above-mentioned hand-held smell release device is used cooperatively and fill It sets.The smell presentation device can be used for presenting the smell of the olfactorin via the release of olfactorin liberation port.

Smell presentation device may include the olfactorin of absorption release so that the disposable unit of smell is presented.The disposable unit Be made of water-absorbing material, and for single smell training or olfactometry (every time training or detection in an olfactorin Release and smelling).Here, water-absorbing material can be absorbent wool, blotting paper, water-absorbing sponge and other can be used for absorbing liquid Material.

Preferably, water-absorbing material can be arranged to carry out smell training or be smelt in the case where not with human contact It is replaced after feeling inspection and use.The disposable absorbent component can be processed to suitable shape, have it is matched packaging and/or Can be matched with other suitable components, with realize using and the whole process of discarding avoid and human contact, to prevent dirt Dye.

For in the case where selling, smell release device of the invention preferably to carry out complete dealer with smell presentation device It sells.In certain embodiments, smell release device and smell presentation device can have the globality in structure.For example, smell Presentation device can be a part of smell release device 10, or can when carrying out smell presentation with smell release device 10 It combines.
