Description

Smoking set and cartridge

Technical Field

The application relates to the technical field of electronic cigarettes, in particular to a smoking set and a smoke cartridge.

Background

At present, the problem that the cartridges of different brands can be interchanged for heating non-combustion electronic cigarettes exists. However, for manufacturers of heating non-combustion electronic cigarettes, the profit brought by the sale of the cartridges produced by the manufacturers is very large, and if the consumers always buy the cartridges produced by another manufacturer for use, great loss is brought to the manufacturers of the electronic cigarettes. Therefore, how to identify the cartridge matched with the smoking set produced by the manufacturer is an important problem to be solved.

Disclosure of Invention

An object of this application part embodiment is to provide a smoking set and cigarette bullet, can reduce the manufacturing cost of smoking set and smoking set when avoiding mixing between the smoking set of different producers and the cigarette bullet.

The embodiment of the application provides a smoking set, includes: the capacitive image sensor is used for identifying a mark made of a capacitive sensitive material on the outer surface of the cigarette cartridge after the cigarette cartridge is inserted into the smoking set; the microcontroller is connected with the capacitive image sensor and used for judging whether the smoking set is matched with the cartridge according to the identification and starting the heating circuit after judging that the smoking set is matched with the cartridge; a heating circuit connected with the microcontroller and configured to heat the cartridge after being turned on.

The embodiment of the application also provides a smoke cartridge, wherein the surface of the smoke cartridge is provided with a mark made of a capacitance sensitive material; the cigarette cartridge is used for being matched with the smoking set.

The inventors found that the related art has at least the following problems: the identification mode between the cartridge and the smoking set is mostly wiring type or radio frequency type, and wired or wireless communication needs to be established between the cartridge and the smoking set. On the other hand, it is difficult to establish a circuit for heating the non-combustion type cartridge, and if a Radio Frequency Identification (RFID) chip is provided, the cost of the cartridge is significantly increased.

Compared with the prior art, the smoking set of the embodiment of the application comprises: the capacitive image sensor is used for identifying a mark made of a capacitive sensitive material on the outer surface of the cigarette cartridge after the cigarette cartridge is inserted into the smoking set; the microcontroller is connected with the capacitive image sensor and used for judging whether the smoking set is matched with the cartridge according to the identification and starting the heating circuit after judging matching; the heating circuit is connected with the microcontroller and is used for heating the cartridge after being started. That is to say, through setting up electric capacity image sensor in the smoking set, utilize the sensitive type material of electric capacity to make the sign on the cigarette bullet surface, can accomplish the matching discernment between smoking set and the cigarette bullet. And because the realization processes of arranging the capacitance image sensor in the smoking set and manufacturing the identification on the surface of the cigarette bullet by using the capacitance sensitive material are simple and convenient, and a complex circuit loop is not required to be established on the cigarette bullet and the smoking set, the difficulty in mass production of the cigarette bullet and the smoking set can be reduced. In addition, the cost of the capacitive image sensor is low, and the identification made of the capacitive sensitive material on the surface of the cigarette cartridge does not have great influence on the production cost of the cigarette cartridge. Therefore, in the embodiment of the application, the cigarette and the cartridge can be identified more simply and conveniently while avoiding the mixed use between the smoking set and the cartridge of different manufacturers, and the production cost of the cartridge and the smoking set is effectively reduced.

For example, a cavity for inserting the cartridge is provided in the smoking set; the capacitance image sensor is embedded in the cavity wall of the cavity or attached to the cavity wall of the cavity. The capacitive image sensor is embedded in the cavity wall and is directly contacted with the inserted smoke cartridge, so that the identification effect on the surface of the smoke cartridge is better; the capacitive image sensor is attached to the cavity wall, namely, the capacitive image sensor is separated from the inserted cigarette cartridge by the cavity wall, so that the capacitive image sensor is prevented from being worn by frequently inserting and pulling out the cigarette cartridge, and the service life of the capacitive image sensor is prolonged.

For example, a heating assembly is arranged in the cavity, and the bottom of the heating assembly is attached to the bottom of the cavity; the top of the heating assembly is spaced from the bottom of the cavity by a first height, the bottom of the capacitive image sensor is spaced from the bottom of the cavity by a second height, and the first height is smaller than the second height. The heating assembly is connected with the heating circuit and is used for heating the cigarette cartridge under the control of the heating circuit. That is, the position of the capacitive image sensor is higher than that of the heating assembly, which is beneficial to avoiding the influence on the capacitive image sensor when the heating assembly starts to heat. Moreover, the height that highly is more than or equal to heating element of the tobacco body that contains the tobacco leaf in the cigarette bullet usually, can make the cigarette bullet insert the cavity back in the top of the tobacco body that contains the tobacco leaf through setting up the sign on the cigarette bullet surface, heating element's height can be less than the regional height in sign place, sign place region whole is located the heating element top promptly, be favorable to avoiding heating element to ooze the sign that the tobacco tar damaged the cigarette bullet surface when heating the cigarette bullet, thereby influence recognition effect.

For example, after the cartridge is inserted into the smoking article, the area of the region where the identifier of the outer surface of the cartridge is mapped on the capacitive image sensor is greater than or equal to a preset area. After the cigarette bullet inserted into the smoking set, the area of the overlapping area between the identification area of the capacitive image sensor and the mapping area of the identification on the capacitive image sensor is larger than the preset area, so that the identification on the cigarette bullet can be effectively and accurately acquired by the capacitive image sensor after the cigarette bullet is inserted into the smoking set.

For example, the area of the area over which the identification of the outer surface of the cartridge is mapped on the capacitive image sensor is equal to the area of the area occupied by the capacitive image sensor. After the cigarette cartridge is inserted into the smoking set, the identification area of the capacitive image sensor is completely overlapped with the mapping area of the identifier on the capacitive image sensor, so that the identification effect is improved, the identifiers on the capacitive image sensor and the cigarette cartridge are not required to be too large during production, and the cost is further reduced.

For example, the capacitive image sensor is provided with a ring along the cavity wall. The design of a circle enables the identification on the cartridge to be more conveniently and accurately identified from each direction.

For example, the smoking article further comprises: a touch sensor connected with the microcontroller; the microcontroller is also used for detecting whether a cigarette cartridge is inserted according to the sensing signal of the touch sensor and controlling the capacitive image sensor to be started after the cigarette cartridge is detected to be inserted. Whether a smoke cartridge is inserted is detected by the touch sensor, the phenomenon that the microcontroller consumes electric quantity due to the fact that the microcontroller needs to send a driving signal to a detection electrode of the capacitive image sensor all the time is avoided, and power consumption is reduced. And the touch sensor is lower in cost, and the cost of smoking set is not greatly influenced by adding the touch sensor.

For example, the touch sensor is integrated with and surrounds the capacitive image sensor. The touch sensor and the capacitive image sensor are integrated together, so that the production and the manufacture are convenient.

For example, the indicia is disposed around an outer surface of the cartridge. The outer surface of the cigarette cartridge is provided with a circle of marks, so that the marks can be conveniently identified by a capacitive image sensor in the smoking set.

For example, the indicia is provided on an outer surface of a filter of the cartridge. The cigarette filter is arranged on the outer surface of the filter tip, so that the tobacco body containing tobacco leaves is prevented from seeping tobacco tar when being heated, and the identification is prevented from being damaged to influence the identification effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clearly understood, some embodiments of the present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.

A first embodiment of the present application relates to a smoking article comprising: the capacitive image sensor is used for identifying a mark made of a capacitive sensitive material on the outer surface of the cigarette cartridge after the cigarette cartridge is inserted into a smoking set; the microcontroller is connected with the capacitive image sensor and used for judging whether the smoking set is matched with the cartridge according to the identification and starting the heating assembly after judging matching; and the heating component is connected with the microcontroller and is used for heating the smoke cartridge after being started. The following detailed description of the present embodiments is provided for ease of understanding and is not intended to limit the scope of the present embodiments.

The schematic cross-sectional view of the smoking set in this embodiment can be as shown in fig. 1, and includes: a housing 100, a heating circuit 101, a microcontroller 102, a capacitive image sensor 103. The heating circuit 101, the microcontroller 102, and the capacitive image sensor 103 are all located in the housing 101. Both the capacitive image sensor 103 and the heating circuit 101 are connected to the microcontroller 102. In one example, referring to fig. 1, the heating circuit 101 and the microcontroller 102 may be disposed on a control circuit board 107. However, fig. 1 is only an example, and in a specific implementation, the heating circuit 101 and the microcontroller 102 may be disposed on different circuit boards according to actual needs, which is not specifically limited in this embodiment.

Specifically, the capacitive image sensor 103 is used to identify the indicia on the outer surface of the cartridge that is made of a capacitive sensitive material after the cartridge is inserted into the smoking article. The capacitance sensitive material may be a conductive material or a material doped with a conductive medium. It will be appreciated that if the outer surface of the cartridge inserted into the smoking article is not marked with a label made of a capacitance-sensitive material, the image captured by the capacitive image sensor 103 is an empty image. The blank picture can be understood as a picture without any material content.

In one example, the outer surface of the cartridge matching the smoking set in fig. 1 is provided with a mark made of capacitance sensitive material, and the mark can be a customized graph, a customized character and the like according to actual needs.

In one example, the indication of the outer surface of the cartridge that matches the smoking set in this embodiment may be provided around the outer surface of the cartridge, i.e. a loop is made on the outer surface of the cartridge. Wherein, the schematic diagram of the cigarette cartridge for making the ring of marks can refer to fig. 2 and fig. 3. Figure 2 may be a schematic cross-section of the cartridge as seen from the front and figure 3 may be a schematic cross-section of the cartridge as seen from the back. The indicia of the outer surface of the cartridge may be located in an indicia zone between P1 and P2, P1 and P2 being relative heights with respect to the bottom P0 of the cartridge. In addition, the identification of the outer surface of the cartridge may be periodic or aperiodic. Here, the periodic mark may be understood as a pattern composed of a plurality of repetitive patterns, and the non-periodic mark may be understood as a pattern having no repetition.

In one example, referring to fig. 1, a cavity 105 is provided within the smoking article for insertion of a cartridge. The cavity 105 may be a hollow, topless cylinder having a diameter generally the same as the diameter of the cartridge, the outer surface of the cartridge conforming to the cavity walls 107 of the cavity 105 and the bottom of the cartridge conforming to the bottom of the cavity 105 when the cartridge is inserted into the cavity 105. The capacitive image sensor 103 may be fitted to the cavity wall 107 of the cavity 105, with the outer surface of the cartridge in indirect contact with the capacitive image sensor 103 when the cartridge is inserted into the cavity 105. Namely, a cavity wall 107 is arranged between the outer surface of the cigarette cartridge and the capacitive image sensor 103, which is beneficial to avoiding the damage of frequent insertion or extraction of the cigarette cartridge to the capacitive image sensor.

In another example, the capacitive image sensor 103 may be embedded within the cavity wall 107, i.e., the capacitive image sensor 103 is in the same plane as the cavity wall 107. After the cartridge is inserted into the cavity 105, the outer surface of the cartridge is in direct contact with the capacitive image sensor 103, so that the transmission effect of a direct contact signal is better, and the identification of the outer surface of the cartridge can be better identified.

In the present embodiment, the capacitive image sensor 103 is embedded in the cavity wall 107 or attached to the cavity wall 107, but in a specific implementation, the capacitive image sensor may be disposed at another position in the smoking set according to actual needs. For example, if the distance V1 between the cavity wall 107 and the side wall of the housing 101 in fig. 1 is smaller than the predetermined distance, the capacitive image sensor 103 may be disposed on the side wall of the housing 100. The preset distance can be set according to actual needs, and the purpose is to indicate that the distance between the cavity wall 107 and the side wall of the housing 100 is small, so that even if the capacitive image sensor 103 is arranged on the side wall of the housing 100, the recognition of the identifier on the outer surface of the cartridge after the cartridge is inserted into the cavity 105 is not affected. However, the position of the capacitive image sensor 103 in the smoking set is not particularly limited in this embodiment.

In addition, whether the capacitive image sensor 103 is embedded in the cavity wall 107 or attached to the cavity wall 107, the surface of the capacitive image sensor 103 may be provided with a protective layer for protecting the capacitive image sensor. The material of the protective layer can be solid material such as glass, ceramic and the like or other coating material.

In one example, the number of the capacitive image sensors 103 may be 1, i.e. attached to a certain position on the cavity wall 107, or embedded in a certain position on the cavity wall 107. Under the condition, the identification on the outer surface of the cigarette cartridge can be arranged in a circle around the cigarette cartridge, so that the identification on the outer surface of the cigarette cartridge can be conveniently and accurately identified by the capacitive image sensor 103 no matter how the cigarette cartridge is inserted. Moreover, only 1 capacitive image sensor is arranged, so that the production cost of the smoking set can be greatly reduced, the volume of the smoke cartridge is small, and the cost is not too high even if the smoke cartridge is provided with a circle of marks made of capacitive sensitive materials on the outer surface. Moreover, the height of the circle of marks can be controlled, for example, the distance between P1 and P2 in FIG. 2, so that the height of the circle of marks is smaller than the preset height, and the production cost of the cartridge can be controlled within a certain range. The preset height may be set according to actual needs, and this embodiment is not particularly limited thereto.

In another example, the number of the capacitive image sensors 103 may be multiple, and multiple capacitive image sensors may be arranged in a circle along the cavity wall 107, such as attaching a circle to the cavity wall 107, or embedding a circle therein. In this case, the outer surface of the cartridge may not need to be marked by a circle, and the capacitive image sensor of the circle on the cavity wall 107 is beneficial to more conveniently and accurately identifying the outer surface of the inserted cartridge.

In one example, the location of the indicia on the outer surface of the cartridge may be more closely matched to the location of the capacitive image sensor 103 after the cartridge is inserted into the smoking article. The higher matching degree can be understood as: after the cartridge is inserted into the smoking set, the area of the region where the identifier of the outer surface of the cartridge is mapped on the capacitive image sensor 103 is greater than or equal to a preset area. The preset area can be set according to actual needs, and the area of the region, where the identifier of the outer surface of the cartridge is mapped on the capacitive image sensor 103, is large.

In one example, the larger area of the region where the indicia of the outer surface of the cartridge is mapped on the capacitive image sensor 103 may be understood as: the area of the overlapping area between the area occupied by the capacitive image sensor 103 on the cavity wall 107 and the area mapped by the identifier on the capacitive image sensor 103 is larger than the preset area, so that the identifier on the outer surface of the cartridge can be identified more clearly and accurately by the capacitive image sensor 103.

For example, referring to fig. 1, the top of the capacitive image sensor 103 is spaced from the bottom of the cavity 105 by a height V2, and the bottom is spaced from the bottom of the cavity 105 by a height V3. After the cartridge is inserted into the cavity 105, the bottom of the cartridge conforms to the bottom of the cavity 105. The spacing height of the top of the logo on the outer surface of the cartridge and the bottom of the cartridge is P2, and the spacing height of the bottom and the bottom of the cartridge is P1. It will be appreciated that the references V2 and V3 can be considered to be the base V0 of the cavity 105 and the references P2 and P1 can be considered to be the base P0 of the cartridge, with V0 coinciding with P0 when the cartridge is inserted into the cavity 105. A first height range is formed between V2 and V3, and a second height range is formed between P2 and P1. Whether the area of the region of the outer surface of the cartridge where the identifier is mapped on the capacitive image sensor 103 is greater than or equal to a preset area may be measured by whether the overlap of the first height range and the second height range is greater than or equal to a preset overlap. The preset overlap ratio may be set according to actual needs, which is not specifically limited in this embodiment. That is, if the overlapping rate of the first height range and the second height range is greater than or equal to the preset overlapping rate, it may be considered that the area of the region where the identifier of the outer surface of the cartridge is mapped on the capacitive image sensor 103 is greater than or equal to the preset area.

In one example, V2 and V3 may be between P2 and P1, or P2 and P1 may be between V2 and V3, so that the capacitive image sensor 103 disposed between V2 and V3 may conveniently and accurately recognize the identifier disposed between P2 and P1.

In one example, after the cartridge is inserted into the smoking article, the area of the area over which the indicia of the outer surface of the cartridge is mapped onto the capacitive image sensor 103 is equal to the area occupied by the capacitive image sensor. That is, the recognizable area of the capacitive image sensor 103 is the same as the area where the logo is mapped on the capacitive image sensor 103. The height of the capacitive image sensor 103 and the mark is set to indicate that V2= P2 and V3= P1. When the cigarette cartridge is produced, the height of the capacitive image sensor 103, namely the value of V2 minus V3, and the height of the identifier, namely the value of P2 minus P1, can be controlled to be the same and smaller, so that the cost of the capacitive image sensor and the identifier which need to be used is reduced, and the aim of reducing the production cost of the smoking set and the cigarette cartridge as much as possible is fulfilled.

Specifically, the microcontroller 102 is configured to determine whether the smoking set is matched with the cartridge according to the identifier, and turn on the heating circuit 101 after determining that the smoking set is matched with the cartridge.

In one example, the capacitive image sensor 103, upon recognizing an identification of the outer surface of the inserted cartridge, may send the recognized identification to the microcontroller 102. It will be appreciated that if the cartridge inserted into the smoking article is a pre-designed cartridge that matches the smoking article, such as the cartridge shown in fig. 2, the identifier received by the microcontroller 102 is the identifier of fig. 2 made of the capacitance-sensitive material on the outer surface of the cartridge. If the cartridge inserted into the smoking article is not a pre-designed cartridge that matches the smoking article, the identification received by the microcontroller 102 may be an empty or non-matching figure. For example, a class a cartridge that is pre-designed to fit a smoking set and is made with identification a using a capacitance sensitive material may be interpreted as a non-matching image by the microcontroller 102 after a class B cartridge that is not pre-designed to fit a smoking set but is also made with identification B using a capacitance sensitive material is inserted into the smoking set.

In another example, the microcontroller 102 may also actively acquire the identification recognized by the capacitive image sensor 103. For example, the microcontroller 102 may monitor the capacitive image sensor 103 in real time or periodically, and acquire the identification as long as the capacitive image sensor 103 is monitored to recognize the identification. Or, after the identification is recognized by the capacitive image sensor 103, preset notification information is sent to the microcontroller 102, and after the microcontroller 102 receives the notification information, the identification recognized by the capacitive image sensor 103 is actively acquired.

The following exemplifies the way in which the microcontroller 102 determines whether the smoking set and the cartridge match according to the identifier:

in one example, the microcontroller 102 may be a microcontroller with an external memory, i.e., the microcontroller 102 itself has memory functionality. A template may be pre-stored in the microcontroller 102, the template being a template that matches an identifier made of a capacitance-sensitive material on the outer surface of the cartridge. For example, if the outer surface of the cartridge is marked with a periodic or repeating pattern, the template stored in the microcontroller 102 may be a periodic pattern. If the marking made on the outer surface of the cartridge is a non-periodic, i.e., non-repeating, pattern, then the template stored in the microcontroller 102 is the entire non-repeating pattern. After the microcontroller 102 obtains the identifier identified by the capacitive image sensor 103, the identified identifier may be matched with the stored template, and if the matching is successful, it may be determined that the cartridge inserted into the smoking set is a cartridge matched with the smoking set.

In another example, where the microcontroller 102 does not have memory functionality of its own, the microcontroller 102 may be integrated with a memory, such as on a control circuit board. For example, the microcontroller may be embodied as a main control chip, and the memory may be embodied as a memory chip. With particular reference to fig. 4, fig. 4 is a schematic cross-sectional view of a smoking article. The main control chip 201, the memory chip 202, and the heating circuit 101 may be integrated on the control circuit board 107. The main control chip 201 is connected to the memory chip 202, and the memory chip 202 may pre-store the template. After the main control chip 201 obtains the identifier identified by the capacitive image sensor 103, the template may be called from the storage chip 202, and the identified identifier is matched with the template, and if the matching is successful, it may be determined that the cartridge inserted into the smoking set is the cartridge matched with the smoking set. It should be noted that, in this embodiment, the main control chip 201, the memory chip 202, and the heating circuit 101 may all be integrated on the control circuit board 107, which is not limited in the specific implementation.

In one example, after obtaining the identifier identified by the capacitive image sensor 103, the microcontroller 102 may perform image analysis on the identifier to obtain an analysis result, and if the analysis result is the same as a preset result, it may determine that the cartridge inserted into the smoking set matches the smoking set. For example, if the preset result is a pattern containing a five-pointed star, then if the microcontroller 102 performs image analysis on the obtained identifier, and the obtained analysis result is that the identifier is the pattern containing the five-pointed star, it can be determined that the cartridge inserted into the smoking set matches the smoking set.

In this embodiment, the manner in which the microcontroller 102 determines whether the smoking set and the cartridge are matched is only the above-mentioned manner, and the specific implementation is not limited thereto.

Additionally, reference may be made to fig. 1 for a description of the manner in which the microcontroller 102 turns on the heating circuit 101 after determining that the cartridge is mated with the smoking article. The microcontroller 102 may control to turn on the heating circuit 101 after determining that the cartridge is matched with the smoking set, and may also adjust the current or voltage of the heating circuit 101. The heating assembly 104 is disposed in the cavity, the heating circuit 101 is connected to the heating assembly 104, and the heating circuit 101 can control the output power of the heating assembly 104 by adjusting the current or voltage of the heating assembly 104, so as to control the heating temperature of the heating assembly 104. For example, the greater the output power of the heating assembly 104, the higher the heating temperature.

In one example, referring to fig. 1, the bottom of the heating element 104 conforms to the bottom of the cavity 105; the heating element 104 may be a heating plate, the top of the heating element 104 is spaced from the bottom of the cavity 105 by a first height V4, and the bottom of the capacitive image sensor 103 is spaced from the bottom of the cavity 105 by a second height V3, the first height being less than the second height, i.e. V4 < V3. That is to say, the entire capacitive image sensor 103 is located above the heating element 104, which is beneficial to avoiding the influence on the capacitive image sensor 103 when the heating element 104 heats. It should be noted that the shape of the heating assembly shown in fig. 1 is only an example, and is not limited in the specific implementation.

Moreover, the height that contains the tobacco body of tobacco leaf in the cigarette bullet usually is more than or equal to heating element 104, can be through setting up the sign on the cigarette bullet surface in the top that contains the tobacco body of tobacco leaf, make the cigarette bullet insert behind cavity 105, heating element 104 highly can be less than the height of the sign district at sign place, the whole top that is located heating element 104 in sign district promptly, be favorable to avoiding heating element 104 to ooze the sign that the tobacco tar damaged the cigarette bullet surface when heating the tobacco body that contains the tobacco leaf in the cigarette bullet, thereby influence the recognition effect. For example, referring to the schematic cross-sectional view of the reverse side of the cartridge in figure 5, the cartridge comprises a tobacco-containing body 301 and a filter 302, and the indication of the outer surface of the cartridge may be provided above the tobacco-containing body 301, i.e. on the outer surface of the filter 302.

In addition, it is understood that a battery 106 is also generally disposed in the housing 101, and as shown in fig. 1, the battery 106 is connected to the control circuit board 107 to supply power to the control circuit board 107.

Compared with the prior art, the embodiment only needs to arrange the capacitance image sensor in the smoking set, and the marks are made on the surface of the smoke cartridge by using the capacitance sensitive material, so that the matching identification between the smoking set and the smoke cartridge can be completed. The realization process of arranging the capacitance image sensor in the smoking set and manufacturing the identification on the surface of the cigarette cartridge by using the capacitance sensitive material is simple and convenient, and a complex circuit is not required to be established on the cigarette cartridge and the smoking set, so that the production cost of the cigarette cartridge and the smoking set is reduced, and the difficulty in mass production of the cigarette cartridge and the smoking set is also reduced. Meanwhile, the cost of the capacitive image sensor is low, and the identification made of the capacitive sensitive material on the surface of the cigarette cartridge cannot greatly influence the production cost of the cigarette cartridge. Therefore, in the embodiment of the application, the cigarette and the cartridge can be identified more simply and conveniently while the mixed use of the cigarette and the cartridge of different manufacturers is avoided, and the production cost of the cartridge and the cigarette is effectively reduced.

The second embodiment of the present application relates to a smoking set, and the working mode of the capacitive image sensor is mainly described in this embodiment, and the working mode of the capacitive image sensor in this embodiment may include full-automatic mode and semi-automatic mode, and the following two working modes are exemplified. First, a fully automatic operation will be explained:

in one example, the capacitive image sensor may be configured to automatically capture images periodically, determine whether a cartridge is inserted by detecting whether an empty image is captured, and adjust the capture period. It will be appreciated that if the capacitive image sensor collects and identifies an empty pattern, it is assumed that no cartridge is inserted, and the collection may continue for a preset collection period. If the image is collected and identified, the preset collection period is adjusted to ensure that the capacitive image sensor can continuously collect the image if the smoke cartridge is probably inserted. The preset acquisition period and the adjusted acquisition period may be set according to actual needs, and this embodiment is not particularly limited to this.

In another example, portions of the detection electrodes of the capacitive image sensor may be multiplexed for touch detection. That is, the capacitive image sensor may be time-multiplexed as a touch sensor for touch detection. The microcontroller can detect whether a cigarette cartridge is inserted according to the sensing signals of part of the detection electrodes, and controls all detection electrodes of the capacitive image sensor to be turned on after the detection that the cigarette cartridge is inserted. For example, a part of all the detection electrodes of the capacitive image sensor is predetermined to be reused for touch detection, and the detection electrode reused for touch detection may be located at a position above the surface of the capacitive image sensor, that is, an area where a cigarette cartridge is first contacted with a label on the surface of the cigarette cartridge after being inserted, so that insertion of the cigarette cartridge can be detected in time. The microcontroller can control the part of the detection electrodes to work continuously, and after the insertion of the cigarette cartridge is detected, all the detection electrodes are controlled to work to identify the surface marks of the cigarette cartridge. It should be noted that the detection electrodes multiplexed for touch detection may be arranged according to actual needs, and are not limited to the position above the surface of the capacitive image sensor. In addition, it can be understood that the number of electrodes multiplexed for touch detection may be small, so that power consumption may be further reduced.

Assuming that one detection electrode corresponds to one acquisition point, the capacitance image sensor has n x m acquisition points, one part of the acquisition points can be controlled to work in advance, and when the change of signals acquired by the part of the acquisition points is detected, the insertion of a smoke cartridge can be considered to be possible. At the moment, other acquisition points can be controlled to start working, namely, the images are acquired by the n multiplied by m acquisition points of the capacitive image sensor together. The number of the acquisition points in the working state in the capacitive image sensor is controlled at different occasions, so that the capacitive image sensor can automatically acquire and identify images and reduce power consumption. In a specific implementation, the above-mentioned adjusting of the acquisition period and controlling of the number of acquisition points may be combined to control the operation mode of the capacitive image sensor. However, this embodiment is not particularly limited thereto.

In another example, a touch sensor may be provided within the smoking article to detect whether a cartridge is inserted. With particular reference to the schematic cross-sectional view of the smoking article of fig. 6, the smoking article of this example further comprises a touch sensor 401 connected to the microcontroller 102, in comparison to the schematic cross-sectional view of the smoking article of fig. 1. Whether a cartridge is inserted is detected by the touch sensor 401.

Specifically, the touch sensor 401 may be disposed on the cavity wall 107, such as embedded in the cavity wall 107 or attached to the cavity wall 107, and the manner of disposing in fig. 4 is to attach to the cavity wall 107. The microcontroller 102 may be configured to detect whether a cartridge is inserted according to a sensing signal of the touch sensor 401, and control the capacitive image sensor to turn on after detecting that a cartridge is inserted. The touch sensor 401 essentially also adopts the capacitive sensing principle to realize detection, and after a cigarette cartridge having a mark made of a capacitive sensitive material on the outer surface is inserted into the smoking set, the touch sensor 401 can detect the change of the internal capacitance thereof by using the capacitive sensing principle, thereby judging that the cigarette cartridge is inserted.

In one example, the touch detection electrodes of the touch sensor 401 may surround the cavity wall 107 to form a circle or a partial area, and the area where the touch detection electrodes are located may contact the mark of the outer surface of the cartridge inserted into the cavity.

In an example, the touch sensor 401 and the capacitive image sensor 103 may be integrated together and surround the capacitive image sensor 103, so that the capacitive image sensor and the touch sensor may be directly integrated into a whole during production, and the whole is conveniently attached or embedded in the cavity wall 107, i.e., the smoking set is convenient to produce.

In one example, the capacitive image sensor and the touch sensor may be integrated on a chip, which is attached to or embedded in the cavity wall 107.

In one example, the smoking set may further include a touch chip connected to the microcontroller, and the touch chip is connected to the touch sensor; the touch control chip is used for detecting whether a cigarette cartridge is inserted according to the induction signal of the touch control sensor and sending detection information to the microcontroller after detecting that the cigarette cartridge is inserted; and when receiving the detection information, the microcontroller controls the capacitive image sensor to be started.

The following describes the semiautomatic operation of the capacitive image sensor:

in one example, the schematic cross-sectional view of the smoking article can be seen in fig. 7, where the smoking article of fig. 7 further comprises, in comparison to fig. 1: and the key 501, the key 501 is connected with the microcontroller 102 in the control circuit board 107 and is used for sending the pressing information to the microcontroller 102 after detecting the pressing information, and the microcontroller 102 controls the capacitive image sensor 103 to be turned on after receiving the pressing information. That is, after the user inserts the cartridge into the smoking set, the user can press the button 501 on the smoking set, thereby controlling the capacitive image sensor 103 to be turned on. In a specific implementation, the key 501 may also be disposed on the control circuit board 107, but this embodiment is not limited to this specifically.

In addition, it should be noted that other devices may be disposed in the smoking set according to actual needs. In one example, an LED light may be provided in the smoking set and controlled to turn on when needed, for example, if the microcontroller 102 determines that the inserted cartridge does not match the smoking set, the LED light may be controlled to alert in the form of a flashing light. A vibration assembly may also be provided within the smoking article and may be controlled to alert in the form of vibration if the microcontroller 102 determines that the inserted cartridge does not match the smoking article. However, the way of reminding the matching failure is not limited to the above two ways, and can be flexibly set according to actual needs. Moreover, in the case of unsuccessful matching, the capacitive image sensor 103 may be controlled to repeat sampling recognition one or more times to guarantee the success rate of recognition.

In one example, a schematic cross-sectional view of a smoking article can be shown in fig. 8, in comparison to fig. 1, which further includes a circuit board 601. The circuit board 601 is connected to the control circuit board 107, and the other devices described above, i.e., the LED lamp, the vibration component, and the like, may be optionally disposed on the circuit board 601. In addition, the other devices can also comprise a display screen, a charging assembly and the like for displaying the related information such as the electric quantity, the working mode and the like of the smoking set besides the LED lamp and the vibration assembly. It should be noted that, devices on the circuit board 601 may be selectively added according to actual needs, and this embodiment is not particularly limited to this.

Compared with the prior art, the implementation mode provides the selectable working mode of the capacitive image sensor, namely whether a smoke cartridge is inserted can be detected by the touch sensor, the capacitive image sensor is prevented from being started all the time, and the reduction of power consumption is facilitated. And the touch sensor is lower in cost, and the cost of smoking set is not greatly influenced by adding the touch sensor. Moreover, the touch sensor and the capacitive image sensor are integrated, so that the production and the manufacturing are facilitated, and meanwhile, the identification of the outer surface of the cigarette cartridge is facilitated.

It should be noted that, in order to highlight the innovative part of the present invention, devices that are not so closely related to solving the technical problems proposed by the present invention are not introduced into the first embodiment and the second embodiment, but this does not indicate that no other devices exist in the present embodiment.

A third embodiment of the present application relates to a cartridge having a surface provided with an identification made of a capacitance-sensitive material for use with the smoking article of the first or second embodiments.

That is, a circle is arranged on the outer surface of the cartridge, the schematic cross-sectional view of the front surface of the cartridge can refer to fig. 2, and the schematic cross-sectional view of the back surface of the cartridge can refer to fig. 3.

In one example, and with reference to figure 5, the cartridge comprises a tobacco-containing body 301 and a filter 302, the indicia being provided on the outer surface of the filter 302 of the cartridge.

That is, this embodiment can be implemented in cooperation with the first or second embodiment. The related technical details mentioned in the first or second embodiment are still valid in the present embodiment, and the technical effects that can be achieved in the first or second embodiment can also be achieved in the present embodiment. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the first or second embodiment. Since the relevant contents of the cartridge matched with the smoking set have already been described in the first or second embodiment, the description thereof will be omitted for the sake of reducing redundancy.

It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the present application, and that various changes in form and details may be made therein without departing from the spirit and scope of the present application in practice.
