Background

An atomising device is a device for heating, baking an aerosol-generating substrate to produce an aerosol for use by a user.

The optimum atomisation pattern varies from aerosol-generating substrate to aerosol-generating substrate, depending on the composition, manufacturing process etc. The atomization mode includes time and temperature of atomization, and a change relationship between time and temperature. In the prior art, there are solutions: the aerosol-generating substrate is identified and the appropriate atomisation pattern is then matched according to the identified aerosol-generating substrate characteristics.

The embodiment of the application provides an atomization device, which comprises a device body and an atomization assembly, wherein the atomization assembly is installed on the device body, the atomization device is provided with a containing cavity, the containing cavity is used for containing aerosol generation substrates, the atomization device further comprises a collector and a light-transmitting piece, and the collector and the light-transmitting piece are installed on the device body; wherein, light-transmitting part is located the axial one end of atomizing component, and light-transmitting part is located and holds between chamber and the collector.

The atomization device comprises a device body and an atomization assembly, wherein the atomization assembly is mounted on the device body and can atomize aerosol to generate a substrate, the aerosol generating substrate is accommodated in an accommodating cavity of the atomization device, and on the basis, the atomization device further comprises a collector and a light transmission piece, and the collector and the light transmission piece are mounted on the device body; wherein, the printing opacity piece is located the axial one end of atomization component, and the printing opacity piece is located and holds between chamber and the collector, also the printing opacity piece is located and holds between the aerosol generation matrix and the collector in the chamber, because aerosol is difficult to permeate into the printing opacity piece, light propagation in the printing opacity piece is then difficult for being influenced by aerosol, this light path receives the influence of aerosol and consequently reduces, can effectively reduce the condensate, the influence of aerosol etc. to the OID light path, be favorable to the collector to obtain the clear accurate aerosol and generate the characteristic information of matrix, thereby OID identification rate and rate of accuracy have been promoted.

In one possible implementation manner of the present application, the atomizing assembly includes an inner wall forming the accommodating cavity, and the light-transmitting member includes a first surface, and the first surface is located on an extension plane of the structural plane where the inner wall is located. So set up, the first surface of light-transmitting piece becomes a part of holding intracavity wall, and the aerosol generation substrate in the accommodation space that more closely is close to reduces the clearance between light-transmitting piece and the aerosol generation substrate for the aerosol is difficult to get into this clearance, with the influence that reduces the aerosol to OID discernment.

In a possible implementation manner of the present application, the atomizing assembly includes an inner wall forming the accommodating cavity, and the light-transmitting member includes a first surface parallel to an extension plane of the structural plane where the inner wall is located. So set up, the relative inner wall protrusion that holds the chamber of first surface of light-transmitting member, the aerosol generation substrate in the accommodation space is pressed close to more, reduces the clearance between light-transmitting member and the aerosol generation substrate for aerosol is difficult to get into this clearance, with the influence that reduces aerosol to OID discernment.

In a possible implementation manner of the present application, the light-emitting device further includes a light emitter, and light emitted by the light emitter is at least partially between the accommodating cavity and the collector. So set up, when ambient light was not enough, the light that the illuminator sent shines to aerosol generation matrix to through aerosol generation matrix reflection to collector, thereby transmit the characteristic information of aerosol generation matrix to collector, promote the discernment rate and the rate of accuracy of collector under the less strong condition of ambient light, widened atomizing device's application scene.

So set up, sealed chamber carries out the separation to aerosol, prevents aerosol to get into between printing opacity piece and the collector for the light path between printing opacity piece and the collector is influenced lessly by aerosol, further promotes the discernment rate and the rate of accuracy of collector.

In a possible implementation of this application, sealed chamber with hold the chamber branch and locate the relative both sides of printing opacity piece, the radial dimension of sealed chamber is along keeping away from and holding the chamber direction and progressively diminishing, sealed chamber is along keeping away from and holding the chamber direction and being the echelonment and extending. So set up, the one end size that the sealed chamber was equipped with the collector is less, and the collector will also be kept away from to the reflection light of illuminator on the chamber wall of sealed chamber, has reduced the light interference to the collector, and the echelonment setting then increases and makes the reflection normal keep away from the collector, and then makes emission light have bigger probability to be reflected to keeping away from the collector direction, further reduces the interference of chamber wall reflection light to the collector.

Referring to fig. 1, 2 and 3, an atomization device provided in an embodiment of the present application includes a device body 1 and an atomization assembly 2, where the atomization assembly 2 is mounted on the device body 1. With reference to figures 2 and 3, the atomising device has a receiving cavity 111, the receiving cavity 111 being for receiving an aerosol-generating substrate 7, the atomising device further comprising a collector 3 and a light transmissive element 4, the collector 3 and the light transmissive element 4 being mounted to the device body 1; wherein, light transmission member 4 is located atomizing assembly 2 axial one end, and light transmission member 4 is located and holds between chamber 111 and collector 3.

Wherein, atomizing component 2 can atomizing aerosol and produce substrate 7, make it produce aerosol, aerosol produces substrate 7 and holds in atomizing device's the chamber 111 that holds, light transmission member 4 is located atomizing component 2 axial one end, and light transmission member 4 is located and holds between chamber 111 and the collector 3, namely light transmission member 4 is located and holds between aerosol production substrate 7 and the collector 3 in the chamber 111, because aerosol is difficult to permeate light transmission member 4, the light propagation in the light transmission member 4 then is difficult to be influenced by aerosol, this light path receives the influence of aerosol and consequently reduces, can effectively reduce the influence of condensate, aerosol etc. to OID light path, be favorable to collector 3 to obtain clear accurate aerosol and produce the characteristic information of substrate 7, thereby OID discernment rate and rate of accuracy have been promoted.

Specifically, the device body 1 includes a housing 11, a power supply, a control module, and the like, and the accommodating chamber 111 is provided in the housing 11, and the accommodating chamber 111 communicates with the outside of the housing 11, wherein the contour of the accommodating chamber 111 may be similar to the contour of the aerosol-generating substrate 7, and the aerosol-generating substrate 7 is fixed, or a holder may be provided in the accommodating chamber 111 to fix the aerosol-generating substrate 7. The atomizing assembly 2 comprises an inner wall 21 forming part of the receiving cavity 111, and when the aerosol-generating substrate 7 is placed in the receiving cavity 111, one end of the inner wall 21 is located in the atomizing assembly 2 for being heated and roasted for atomization by the atomizing assembly 2, and the other end of the inner wall corresponds to the position of the light-transmitting member 4.

In addition, power, control module group, collector 3 and printing opacity piece 4 all set up in casing 11, and the power electricity is coupled in atomizing subassembly 2, control module group, collector 3 etc for provide the electric energy to atomizing subassembly 2, control module group and collector 3 etc..

On this basis, atomizing subassembly 2 and collector 3 all electric link in control module group, control module group can be used to control the opening of atomizing subassembly 2 and stop, heating temperature, heating time etc, collector 3 is arranged in to putting into the aerosol generation substrate 7 that holds in chamber 111 and carries out optics collection, gather the characteristic information that aerosol generated substrate 7, and transmit this characteristic information to control module group, in order to supply control module group to judge the type that aerosol generated substrate 7, control module group is according to judged result, aerosol generation substrate 7 that corresponds the different grade type sets up different heating strategies, for example, heating time length, heating temperature height etc. and according to this heating time and the heating temperature isoparametric of control atomizing subassembly 2, make every kind of aerosol generation substrate 7 can both obtain best result of use, in order to promote user's experience.

Optionally, the control module may be embedded with a plurality of heating programs for atomizing media, and may further include other human-computer interaction components, for example, a display screen and an indicator light may show information such as start/stop, heating state, and electric quantity of the device to a user; for another example, the switch button, the knob, the touch screen, the fingerprint identifier, etc. may be used to operate the atomizing device.

Referring to fig. 4 and 5, light transmissive member 4 includes a first surface 41 distal from collector 3. When atomized condensate is attached to the first surface 41, the change of the droplet on the light propagation may result in that the target image cannot be acquired by the collector 3 or the acquired image is inaccurate, resulting in a final recognition result. To solve this problem, the invention proposes a solution to the problem that, by arranging the aerosol-generating substrate 7 in the receiving cavity 111 of the first surface 41 as close as possible, even if droplets are deposited on the first surface 41, the droplets are squeezed as the first surface 1 is attached to the aerosol-generating substrate 7, so that the lens effect of the droplets is reduced, the effect of the droplets on changing the propagation of light is reduced, and the probability of acquiring the target image by the acquiring device 3 is higher and the acquired target image is more accurate. In order to keep the first surface 41 and the receiving cavity 111 as close as possible, the first surface 41 has various positions relative to the inner wall 21 of the atomizing assembly 2.

Referring to fig. 4, in one possible implementation of the present application, the first surface 41 is located on an extension of the structural plane of the inner wall 21. The first surface 41 of the light-transmissive member 4 forms part of the inner wall 21 of the receiving cavity 111 and is more proximate to the aerosol-generating substrate 7 in the receiving space, reducing the gap between the light-transmissive member 4 and the aerosol-generating substrate 7, and in particular when the aerosol-generating substrate 7 and the inner wall 21 of the receiving cavity 111 are contoured, the first surface 41 may be attached to the aerosol-generating substrate 7 to reduce aerosol generation between the light-transmissive member 4 and the aerosol-generating substrate 7, and also to effectively reduce condensation of aerosol on the light-transmissive member 4 to form droplets, and to reduce the impact of aerosol on OID identification.

Referring to fig. 5, in another possible implementation of the present application, the first surface 41 is parallel to an extension of the structural plane of the inner wall 21. I.e. the first surface 41 may be convex or concave relative to the inner wall 21, the first surface 41 of the light transmissive member 4 may be convex relative to the inner wall 21 of the receiving cavity 111, and may be more proximate to the aerosol-generating substrate 7 within the receiving space, reducing the gap between the light transmissive member 4 and the aerosol-generating substrate 7, making it more difficult for aerosol to enter the gap, in particular when the first surface 41 is attached to the aerosol-generating substrate 7, reducing aerosol generation between the light transmissive member 4 and the aerosol-generating substrate 7, and effectively reducing condensation of aerosol on the light transmissive member 4 to form droplets, to reduce the impact of aerosol on OID identification.

It should be noted that, when the aerosol-generating substrate 7 is placed in the accommodating cavity 111, the aerosol-generating substrate 7 may pass through the atomizing assembly 2 and then pass through the light-transmitting member 4, that is, the light-transmitting member 4 is closer to the position where the accommodating cavity 111 communicates with the outside than the atomizing assembly 2, and the aerosol-generating substrate 7 may also pass through the atomizing assembly 2 again by passing through the light-transmitting member 4, that is, the atomizing assembly 2 is closer to the position where the accommodating cavity 111 communicates with the outside than the light-transmitting member 4.

Optionally, when light-transmitting member 4 is closer to the position of holding chamber 111 and outside intercommunication relative atomizing component 2, aerosol-generating substrate 7 is earlier through light-transmitting member 4 by collector 3 collection characteristic information, then is heated and atomized in getting into atomizing component 2, so set up, can reduce mutual interference between collector 3 and the atomizing component 2, both can reduce atomizing component 2's high temperature to collector 3's influence, also can make atomizing component 2 seal relative collector 3, the aerosol that produces after the heating can flow out through the predetermined route, use for the user.

Furthermore, there are many possible implementations of the receiving cavity 111, for example, the receiving cavity 111 is a through hole opened in the housing 11 and allowing the aerosol-generating substrate 7 to pass through at both ends, and for example, the receiving cavity 111 is a receiving groove opened in the housing 11 and closed at one end and opened at one end.

It should be noted that the present application is not limited to the form of the carrier of the characteristic information, for example, the carrier of the characteristic information may be red, orange, yellow, green, cyan, blue, violet, etc. light with different colors, and different types of aerosol-generating substrates 7 may reflect light with different colors; as another example, the carrier of characteristic information is a pattern in the shape of a triangle, a quadrilateral, a circle, etc., and the aerosol-generating substrate 7 is provided with a pattern of one or a combination of multiple patterns, so that different types of aerosol-generating substrates 7 have different patterns thereon; for another example, the carrier of the characteristic information may be formed by the material of the aerosol-generating substrate 7, and may have different light reflecting effects of materials such as metal, plastic, paper, and the like, or different light reflecting effects of different surface roughness such as frosted surface, high gloss surface, and the like.

On the basis, the aerosol generating substrate 7 can be printed, painted, engraved, pasted, and the like to form characteristics such as color, shape, material, and the like, the characteristics can be integrally arranged on the surface of the aerosol generating substrate 7, or can be locally arranged on the aerosol generating substrate 7, optionally, a mark area 71 is arranged on the aerosol generating substrate 7, the mark area 71 is in a two-dimensional code or dot code form, for example, a 10 × 3 array of dot codes shown in fig. 7, the two-dimensional code or dot code can store more information, and anti-counterfeiting information or factory information and the like can be recorded, so as to realize anti-counterfeiting and information tracing.

Correspondingly, the collector 3 can adopt a color sensor, a laser ranging sensor, a camera and the like, and any sensor capable of collecting one or more kinds of characteristic information can be adopted.

In addition, the material of the light-transmitting member 4 may be selected from various materials, such as glass, quartz, polymethyl methacrylate (PMMA), polycarbonate (PC), acrylonitrile Butadiene Styrene (ABS), and the like, which are not limited in this application.

In order to better conform the first surface 41 to the aerosol-generating substrate 7, there are a number of possible forms for the first surface 41, for example, the first surface 41 is planar and may be adapted to fit a cuboid-shaped aerosol-generating substrate 7, or an end face of a cylindrical aerosol-generating substrate 7; as another example, the first surface 41 is a curved surface for fitting to a cylindrical aerosol-generating substrate 7 or the like.

Furthermore, the attachment of the first surface 41 to the aerosol-generating substrate 7 in the present application may be such that the aerosol generated by the aerosol-generating substrate 7 does not affect the accurate identification of the collector 3, e.g. the distance between the first surface 41 and the aerosol-generating substrate 7 is less than or equal to 1mm, which may achieve the above-mentioned effect, the smaller the distance the better the effect of preventing the ingress of aerosol.

In order to further reduce the influence of aerosol on the light path, the air seal can be arranged between the light-transmitting piece 4 and the collector 3, so that a good light path is formed between the light-transmitting piece 4 and the collector 3, in addition, the air seal between the light-transmitting piece 4 and the collector 3 can also avoid the entering of external dust and the like, and the influence of environmental factors on the collector 3 is further reduced.

It should be noted that there are many possible implementations regarding the air seal arrangement between the light-transmitting member 4 and the collector 3, for example, one side of the light-transmitting member 4 facing the collector 3 is attached to the collector 3, so that aerosol is difficult to enter between the light-transmitting member 4 and the collector 3; or, an air sealing element is arranged between the light-transmitting member 4 and the collector 3 to isolate the light path channel between the light-transmitting member and the collector from the outside, which is not limited in the present application.

Referring to fig. 2 and 3, in one possible implementation of the present application, housing 11 further includes a sealed cavity 112, at least a portion of the surface of light-transmitting member 4 forms a portion of the cavity wall of sealed cavity 112 to separate and hermetically seal accommodating cavity 111 and separated sealed cavity 112, and collector 3 and light-transmitting member 4 are both located in sealed cavity 112. Sealed chamber 112 keeps apart the atmoseal with holding chamber 111 to reach good isolation aerosol effect, effectively avoid aerosol or dust etc. to invade sealed chamber 112, collector 3 and printing opacity piece 4 set up in sealed chamber 112, can obtain good leaded light environment, in order to improve OID recognition rate and rate of accuracy.

Specifically, the light-transmitting member 4 is disposed between the accommodating cavity 111 and the sealing cavity 112, that is, the sealing cavity 112 and the accommodating cavity 111 are disposed on two opposite sides of the light-transmitting member 4, so as to separate the sealing cavity 112 and the accommodating cavity 111 for air sealing. The use of a light-transmissive member 4 for air sealing ensures that the light-transmissive member 4 is both adjacent to the aerosol-generating substrate 7 and in close proximity to the aerosol-generating substrate 7, and also serves to hermetically seal the sealed cavity 112 from the receiving cavity 111.

It should be noted that the present application does not limit the position of the sealed cavity 112, for example, the sealed cavity 112 and the accommodating cavity 111 are arranged coaxially, the sealed cavity 112 is located at the end of the accommodating cavity 111 along the direction in which the aerosol-generating substrate 7 is inserted into the accommodating cavity 111, the collector 3 collects characteristic information on the end face of the aerosol-generating substrate 7, and the axial direction of the sealed cavity 112, i.e. the extending direction thereof, is consistent with the axial direction of the accommodating cavity 111.

With reference to figures 2 and 6, in one possible implementation of the present application, the sealed cavity 112 is arranged on the peripheral side of the receiving cavity 111, i.e. in the direction of movement of the aerosol-generating substrate 7, the sealed cavity 112 is arranged perpendicular to the direction of insertion of the aerosol-generating substrate 7 into the receiving cavity 111, the collector 3 collects characteristic information on the peripheral side of the aerosol-generating substrate 7, and the axial direction of the sealed cavity 112 is the radial direction of the receiving cavity 111.

For convenience of description, a first direction, a second direction and a reference plane are defined, the first direction is arranged in parallel with the first surface 41, it should be noted that, when the first surface 41 is a plane, the first direction is any direction parallel with the first surface 41, and when the first surface 41 is a cylindrical surface, the first direction is a central axis direction of the cylindrical surface; the reference plane is a plane where the light source center 52 of the light emitter 5, the lens center 31 of the collector 3 and the center of the light-transmitting piece 4 are located; the second direction and the first direction are arranged perpendicularly in the reference plane. In addition, the collector 3 has a field range, which is a tapered region enclosed by the field limits 32 shown in fig. 8 to 13, and light entering the field range can be collected by the collector 3.

When the aerosol-generating substrate 7 is cylindrical, the marking zone 71 is generally circumferentially arranged around the aerosol-generating substrate 7, and when the aerosol-generating substrate 7 is inserted into the receiving cavity 111, the marking zone on the side facing the collector 3 is generally difficult to determine, and in order to enable the collector 3 to identify from different angles of the aerosol-generating substrate 7, the size of the first surface 41 should be adapted to the size of the marking zone 71 on the aerosol-generating substrate 7, i.e. the width of the window of the collector 3 at the first surface 41 should be adapted to the size of the marking zone 71 on the aerosol-generating substrate 7.

Referring to fig. 6 and 7, taking the dot code mark region 71 with the size of X (where X ≦ 3 mm) of the single effective identification mark 711 as an example, the size of the first surface 41 of the light-transmissive member 4 satisfies:

L≥2*X；

wherein L is the dimension of the first surface 41 in the radial direction of the atomizing assembly; x is the dimension of a single valid identifier 711 on the aerosol-generating substrate 7 in the radial direction of the atomizing assembly, wherein the valid identifier 711 is intended to be picked up by a collector.

Furthermore, the mark region 71 has an extension S ≧ 6*X, where the extension of the mark region 71 means the length of the mark region 71 in the radial direction of the aerosol-generating substrate 7 after being arranged on the peripheral side of the aerosol-generating substrate 7 and being spread out as a plane.

Because the width of the window of the collector 3 at the first surface 41 is more than twice the size of a single effective identification mark 711 on the aerosol-generating substrate 7, after the object to be identified is inserted into the accommodating cavity, at least one complete effective identification mark 711 enters the field range of the collector 3 and can be identified by the collector 3, i.e. the identification rate is increased, and the orientation of the effective identification mark 711 on the aerosol-generating substrate 7 does not need to be limited, which is convenient for the use of the atomizing device of the present application.

Correspondingly, the height B of the window, which refers to the dimension of the sealed chamber 112 in the first direction, is greater than or equal to X, and the height H of the marking zone 71, which refers to the dimension of the marking zone 71 in the first direction, is greater than or equal to X, such that a complete acquisition of the marking zone 71 by the collector 3 is only possible if the aerosol-generating substrate 7 is fixed in place in the receiving chamber 111.

Accordingly, a plurality of different effective identification marks 711 may be provided along the axial direction of the aerosol-generating substrate 7, providing a basis for the collector 3 to determine the insertion depth of the aerosol-generating substrate 7, the collector 3 determining the current insertion depth of the aerosol-generating substrate 7 by corresponding the identified effective identification marks 711 to a preset depth value. And the central axis 712 of the bottom row of valid signatures 711 in the signature area 71 should be flush with the lens center 31 of the harvester 3.

In addition, the sealing cavity 112 of the present application may adopt an equal-diameter structure or a variable-diameter structure, and the cavity wall of the sealing cavity 112 may be smooth or angular, which is not limited in this application.

In order to obtain a better field of view for the collector 3, referring to fig. 2, 3 and 6, in one possible implementation of the present application, the radial dimension of the sealed cavity 112 is gradually reduced in a direction away from the accommodating cavity 111, that is, the sealed cavity 112 forms a horn-shaped structure, the radial dimension of the end provided with the collector 3 is smaller, and the radial dimension of the end close to the accommodating cavity 111 is larger.

On this basis, in order to reduce the interference caused by the light reflection on the characteristic information acquisition of the acquirer 3, referring to fig. 2, fig. 3 and fig. 6, in a possible implementation manner of the present application, the sealing cavity 112 extends in a step shape along the direction away from the accommodating cavity 111, and the inner wall of the sealing cavity 112 is reduced in a step shape, so that when the light irradiates on the inner wall of the sealing cavity 112, the light is reflected to the direction facing the opening of the sealing cavity 112 at a higher probability, that is, the interference light entering the field range of the acquirer 3 due to the reflection of the inner wall of the sealing cavity 112 is reduced, thereby improving the identification rate and accuracy of the OID.

It should be noted that, the identification module 2 of the present application can utilize ambient light, such as sunlight, indoor lighting, etc., when in use; light generated by the body of aerosol-generating substrate 7, such as a fluorescent coating or the like; as another example, a dedicated light source is provided.

In order to provide sufficient light and enable the collector 3 to collect characteristic information with better brightness, referring to fig. 3 and 8, in a possible implementation manner of the present application, the identification module 2 for an atomizer further includes a light emitter 5, light emitted by the light emitter 5 is at least partially between the accommodating cavity 111 and the collector 3, that is, the light emitter 5 can generate auxiliary light 51, and the auxiliary light 51 can be reflected by the aerosol-generating substrate 7 in the accommodating cavity 111 and then carries the characteristic information and is collected by the collector 3.

The Light emitter 5 may be in various forms, for example, the Light emitter 5 is a fluorescent lamp, an LED (Light-emitting Diode) lamp, or the like, and can emit visible Light; for another example, the light emitter 5 is an ultraviolet lamp or an infrared lamp, and may emit ultraviolet light or infrared light correspondingly, and only needs to satisfy that the auxiliary light 51 is reflected by the aerosol-generating substrate 7 and then collected by the collector 3, and optionally, an LED light source capable of emitting infrared light is adopted as the light emitter 5 in the present application.

In addition, the position of the illuminator 5 is not limited in the present application, and it is only necessary to ensure that the auxiliary light 51 emitted by the illuminator 5 finally falls into the field range of the collector 3.

Referring to fig. 8 to 13, in one possible implementation manner of the present application, the light source center 52 of the light emitter 5 and the lens center 31 of the collector 3 are sequentially disposed along the first direction. On the basis, the light-transmitting member 4 further comprises a second surface 42 facing the collector 3, and the auxiliary light 51 emitted by the light emitter 5 may enter the field of view of the collector 3 after being reflected by the first surface 41 or the second surface 42 of the light-transmitting member 4, so as to form a highlight spot on the image of the aerosol-generating substrate 7 collected by the collector 3, which may affect the recognition effect.

Specifically, referring to fig. 8, when the auxiliary light 51 emitted by the light emitter 5 irradiates a point a on the second surface 42, a part of the auxiliary light is reflected by the second surface 42, the point a is located within the field of view of the collector 3, and when the reflected light passes through a middle point M between a light source center 52 and a lens center 31, a highlight spot is formed on the image collected by the collector 3, wherein the normal reflected by the point a is a reference line (shown by a dotted line passing through the point a in fig. 8) passing through the point a and perpendicular to the second surface 42.

Referring to fig. 9, when the auxiliary light 51 emitted from the light emitter 5 passes through the point X of the second surface 42, because the second surface 42 is a solid-gas interface, refraction occurs, and the refracted light is partially reflected by the first surface 41 when reaching the point Z of the first surface 41, and the reflected light finally reaches the point Y of the second surface 42, where the point Y is located within the field of view of the collector 3, and when the reflection normal of the point Z passes through the midpoint N of the line connecting the point X and the point Y, a highlight spot is formed on the image collected by the collector 3, where the reflection normal of the point Z refers to a reference line (a dotted line shown in fig. 9 and passing through the point Z) perpendicular to the first surface 41.

In order to avoid the interference of the reflected light of the auxiliary light 51 on the light-transmitting member 4 with the operation of the collector 3, referring to fig. 10 to 13, the extending direction of the second surface 42 is disposed at an angle to the first direction along the reference plane, so that the auxiliary light 51 is offset from the light source center 52 of the light emitter 5 after being reflected by the light-transmitting member 4.

Referring to fig. 10 and 11, in a possible implementation manner of the present application, the second surface 42 is an arc surface, the second surface 42 is concavely disposed on the light-transmitting member 4, a curvature center of the second surface 42 is flush with a lens center 31 of the collector 3, and optionally, the curvature center of the second surface 42 is coincident with the lens center 31, and the arrangement is such that a reflection normal of the auxiliary light 51 on the second surface 42 passes through the lens center 31 (for example, at a point a shown in fig. 10), and an incident line and a reflection line are symmetrical with respect to the reflection normal, and accordingly, the reflection light is prevented from passing through the lens center 31; in addition, because of the radian of the second surface 42, the reflection normal of the auxiliary light 51 on the first surface 41 is also dislocated with the midpoint N of the connecting line of the point X and the point Y, so that the light refracted by the point Y is dislocated with the lens center 31, thereby solving the problem of occurrence of highlight spots in the image collected by the collector 3, wherein the second surface 42 may be a cylindrical surface or a spherical surface.

On this basis, in order to reduce distortion of the image acquired by the acquirer 3 and facilitate image processing, optionally, in a possible implementation manner of the present application, the second surface 42 is a spherical surface, and a spherical center of the second surface 42 is overlapped with the lens center 31.

Referring to fig. 12 and 13, in another possible implementation of the present application, the second surface 42 is a plane, the second surface 42 includes a first portion adjacent to the collector 3 and a second portion adjacent to the light emitter 5, the second surface 42 is disposed obliquely to the first surface 41, and a distance between the first portion and the first surface 41 is greater than a distance between the second portion and the first surface 41. That is, along the reference plane, the second surface 42 is disposed at an acute angle to the first direction, and the distance between the second surface 42 and the lens center 31 along the second direction is greater than the distance between the second surface 42 and the light source center 52 along the second direction.

So set up, when auxiliary light 51 reflects at the point B of second surface 42, although point B is located collector 3's field of view scope, but point B's reflection normal passes through camera lens center 31, with the second surface 42 of above-mentioned arc surface form, can make reflection light misplace with camera lens center 31, and auxiliary light 51 light after the reflection of point A is along with passing through camera lens center 31, but point A is outside collector 3's field of view scope, consequently can not be gathered by collector 3, and simultaneously, point Z's reflection normal also misplaces with the line center N of point X and point Y, and then make light after point Y refracts misplace with camera lens center 31, consequently, the problem that the highlight facula appears in the image has been solved.

The included angle between the second surface 42 and the second direction may be any value in the range of 5 to 85 degrees, and may be specifically adjusted according to the length of the window, and optionally, in a possible implementation manner of the present application, the included angle is 11 degrees.

Furthermore, in order to reduce the influence of ambient light on collector 3, referring to fig. 3, in one possible implementation of the present application, a filter 6 is further included, filter 6 is disposed between collector 3 and aerosol-generating substrate 7, and filter 6 allows only light in the wavelength range of auxiliary light 51 to pass through.

The filter 6 can filter out light outside the wavelength range of the auxiliary light 51, which is not an absolute range, but an approximate range, for example, when the light emitter 5 emits infrared light, the wavelength range of the infrared light is 750mm to 850mm, and the filter can filter out light outside the wavelength range of 740mm to 860 mm.

The filter 6 may be a separately provided element, or may be the light-transmitting member 4 itself, for example, the light-transmitting member 4 is made of a filter material, or the light-transmitting member 4 is provided with a filter plating layer or the like.

For the purpose of illustrating the effect of the present application, reference is made to the image captured by the collector 3, and reference is made to fig. 14, which is an image of the light transmissive member 4 at a distance of 3mm from the aerosol-generating substrate 7; referring to figure 15, there is an image of the light-transmissive member 4 at a distance of 3mm from the aerosol-generating substrate 7 and with aerosol; referring to figure 16, an image of the light-transmissive member 4 at a distance of 3mm from the aerosol-generating substrate 7 with droplets of aerosol condensate; referring to fig. 17, an image in which a highlight spot exists; referring to figure 18, this is the image when the light-transmissive member 4 is fitted to the aerosol-generating substrate 7, and is the image without the highlight spots.
