Background
In the modelling of sensory life, odour delivery devices are increasingly used because of their ability to deliver taste materials. Generally, in the conventional scent transmission method, scent is transmitted by inputting scent materials into a scent generation barrel, and scent molecules emitted from the scent materials flow out from an outlet of the scent generation barrel along with the natural flow of air, so as to realize transmission toward a transmission object.

In this way, during the transport towards the transport object, not only can the odor molecules scattered all around be intensively transported to the transport object, but also the surrounding environment is particularly easily contaminated or influenced.
The above-mentioned drawbacks or problems related to the transmission of odors have not been effectively solved at present. In these pending areas, it would be desirable to further improve upon the scent delivery process to enhance or optimize the scent delivery.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
As shown in fig. 1, a first aspect of the present invention provides a method for directional transmission of smells, comprising the following steps S101-S104:
s101, acquiring emission parameters of an odor vortex ring emission device; in some embodiments, the structure of the odor vortex ring emission device can be seen in fig. 2, wherein the odor vortex ring emission device includes a vortex ring generation cavity 112 for outputting an odor vortex ring and an outlet 111, the outlet 111 is communicated with the vortex ring generation cavity 112, and the emission parameter includes at least one of a structural parameter of the outlet 111 and a volume change parameter of the vortex ring generation cavity 112.
S102, acquiring transmission parameters of the odor vortex ring, wherein the transmission parameters at least comprise one of a size or dimension parameter, a transmission distance parameter, a transmission time parameter or a transmission speed parameter of the odor vortex ring, the transmission distance is a distance for the odor vortex ring to be transmitted from the outlet 111 to a target, and the transmission time is a time for the odor vortex ring to be transmitted from the outlet 111 to the target; the target refers to the transmission object of the smell vortex ring, such as a human or other organisms with sense.
S103, acquiring the corresponding relation between the transmission parameters and the transmission parameters.
S104, acquiring target emission parameter information according to the preset conditions and the corresponding relation, wherein the target emission parameter information is used for enabling the odor vortex ring emission device to output a target odor vortex ring with target transmission parameter information so as to transmit odor.
It should be noted that the odor vortex ring emitting device is mainly used for emitting the odor vortex ring, and specifically, the odor vortex ring emitting device outputs a predetermined odor vortex ring from the outlet 111 through the change of the volume of the vortex ring generating chamber 112. The operating principle of the odor vortex ring emission device is as follows: after the odor material is provided to the vortex ring generation cavity 112, when the volume of the vortex ring generation cavity 112 changes, the airflow emitted from the vortex ring generation cavity 112 is output from the outlet 111, and under certain conditions, an odor vortex ring can be formed.
The emission parameters mainly refer to the structural parameters of the odor vortex ring emission device, such as the size of the outlet 111 and the volume change of the vortex ring generation cavity 112, which are described above.
The transmission parameters are mainly used for representing the state of the odor vortex ring after being output from the odor vortex ring emitting device, such as the size or the dimension of the odor vortex ring, the transmission distance, the transmission time or the transmission speed.
It should be noted that the structural parameters of the outlet 111 mainly refer to parameters affecting the structure of the outlet 111, and the structure of the outlet 111 mainly includes two parts, namely, a shape and a size, so the structural parameters of the outlet 111 include at least one of the shape parameters of the outlet 111 and the size parameters of the outlet 111. Similarly, the volume change parameter mainly refers to a parameter that affects the volume change of the vortex ring generation chamber 112.
Based on the characteristics of fluid mechanics, it is easy to understand that the structural condition of the outlet 111 and the change of the volume of the vortex ring generation cavity 112 are related to the state of the odor vortex ring, for example, when the two aforementioned factors are changed, the size, the transmission distance, the transmission speed, etc. of the odor vortex ring can be affected accordingly. It will be appreciated, therefore, that when the emission parameters are varied, the transmission parameters will be correspondingly varied, i.e. the state of the odour vortex ring will be correspondingly changed. Based on the above concept, after the corresponding relationship between the emission parameters and the transmission parameters is established, the target emission parameter information can be obtained from the corresponding relationship according to the predetermined condition, so that the odor vortex ring emission device can output the odor vortex ring with the target transmission parameter information to transmit the odor. For example, a specific target transmission parameter information is given in a predetermined condition, so that the odor vortex ring emitting device outputs a corresponding odor vortex ring.
It is easy to understand that the odor vortex ring has the physical characteristics of the vortex ring, so that the odor molecules or the vapor molecules can be gathered together in the form of the vortex ring for transmission, and thus the odor molecules or the vapor molecules can be directionally transmitted to a transmission object. Just so, the directional transmission method of smell that this application provided can avoid the unordered diffusion of smell molecule or vapour smell molecule in the smell transmission process, reduces the waste to the taste material, improves transmission efficiency.
On the basis of the above, by further defining target transmission parameter information in a predetermined condition, such as the transmission speed and the size of the smell vortex ring, the smell vortex ring emitting device can be enabled to emit the smell vortex ring with corresponding strength, and it is easy to understand that the stronger the smell vortex ring is, the greater the ability of the smell vortex ring to agglomerate the smell molecules is, and the easier the directional transmission is. Similarly, given the transmission distance of the target odor vortex ring, the corresponding emission parameter information can also be obtained, so that the odor molecules can be transmitted by the corresponding distance.
Further, as shown in fig. 2, the odor vortex ring emitting device further comprises an odor vortex ring generator, the odor vortex ring generator comprises a cavity 11 and a compression mechanism 12 connected to the cavity 11, wherein the cavity 11 is used for providing the vortex ring generating cavity 112 and the outlet 111 communicated with the vortex ring generating cavity 112, and the compression mechanism 12 is used for compressing the volume space of the vortex ring generating cavity 112, so that the vortex ring generating cavity 112 outputs the odor vortex ring from the outlet 111.
With regard to the compression mechanism 12, in some embodiments, it may be configured to: the compression mechanism 12 includes a compression end 121 that compresses the volume of the vortex ring generation chamber 112 as the compression end moves (e.g., telescopes in a piston-like motion).
On the basis of the above, the volume change parameter may be determined or obtained according to at least one of a stretching speed parameter of the compression end 121 of the compression mechanism 12, a stretching acceleration parameter of the compression end 121 of the compression mechanism 12, a compression distance parameter of the compression end 121 of the compression mechanism 12, and a compression surface size parameter of the compression end 121 of the compression mechanism 12. In other words, in certain embodiments, the volume change parameter comprises at least one of a telescoping velocity parameter of the compression end 121 of the compression mechanism 12, a telescoping acceleration parameter of the compression end 121 of the compression mechanism 12, a compression distance parameter of the compression end 121 of the compression mechanism 12, and a compression face size parameter of the compression end 121 of the compression mechanism 12.
Further, as shown in fig. 2, the odor vortex ring emission device further comprises at least one odor feeding mechanism 20; wherein, the odor supply mechanism 20 is used for supplying odor material to the odor vortex ring generator, so that the odor vortex ring generator generates and outputs odor vortex rings.
As for step S101, more specifically, the acquiring of the emission parameters of the odor vortex ring emission device may be implemented as follows: the structure of the odor vortex ring emission device, particularly the structure related to the transmission parameters of the odor vortex ring, is determined, and then the emission parameters are determined according to the structure.
In some embodiments, the method for directional transmission of scent further comprises: and acquiring a structure model diagram of the odor vortex ring emission device, carrying out meshing on the structure model diagram, and recording the meshing process into a macro file. The structural model map can be a two-dimensional map or a three-dimensional map; more specifically, the structural model map can be obtained by existing modeling software for mechanical structures, such as CAD software, solid work software, pro software, and the like. When the structure of the odor vortex ring emitting device changes, the changed odor vortex ring emitting device can be automatically subjected to meshing by calling the macro file, and the structural parameters of the odor vortex ring emitting device are quickly acquired. Therefore, the compatibility of the directional transmission method for the smells provided by the invention to the smells with different structures can be improved.

Specifically, sampling is performed according to the transmission parameters, and a plurality of pieces of transmission parameter information are obtained. Illustratively, the size parameter of the outlet 111 and the volume change parameter may be assigned to obtain the plurality of emission parameter information, for example, a plurality of emission parameter information corresponding to numbers 1-3 as shown in table 1 below:

S202, acquiring a plurality of corresponding transmission parameter information according to the plurality of transmission parameter information;
specifically, a computational fluid dynamics (CFD method) may be used to perform numerical simulation on the plurality of emission parameter information obtained in step S201 to obtain a flow chart corresponding to each emission parameter information, and then obtain transmission parameter information corresponding to each flow chart according to each flow chart, that is, each flow chart corresponds to one transmission parameter information. Thus, a plurality of transmission parameter information corresponding to the plurality of transmission parameter information can be obtained.
Flowgrams may be acquired according to computational fluid dynamics software, such as Fluent, cfx, STAR-CCM, comsol, OpenFOAM, Phoenic, and the like. The flow spectrogram can express a two-dimensional or three-dimensional flow field, and can be determined according to the needs of a person skilled in the art.

Also illustratively, in some embodiments, the obtained plurality of transmission parameter information may be as described in corresponding records nos. 1-3 of table 2 below:
