Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and more specifically to an aerosol generating product and an electronic cigarette. Background Art

[0002] In the design and use of electronic cigarettes, a key technology is to ensure that the aerosol generating device can correctly identify the aerosol generating product. In order to achieve this goal, designers usually set a detection component in the aerosol generating device and a test piece in the aerosol generating product. The function of the detection component is to sense the presence of the test piece, allowing the system to determine whether the aerosol generating product has been correctly inserted into the aerosol generating device. This detection mechanism can be implemented based on a variety of technologies, such as magnetic induction, resistance change induction, optical recognition, etc. Magnetic induction can identify the test piece in a non-contact manner, but it may be interfered by other magnetic objects in the surrounding area, and misjudgment may occur. This misjudgment may not only cause the device to fail to work properly (for example, the heating process cannot be started), but may also pose a risk to the safety of the device or the user (for example, the heating process is started incorrectly).

[0056] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0057] In this document, ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of the "second component", and the term "second component" itself does not imply the existence of the "first component".

[0058] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0059] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0060] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0061] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0062] In the prior art, the information (e.g., magnetic field changes) of the detected part (e.g., magnetic part) is detected by the detection part 220 (e.g., Hall sensor) to achieve distance or position monitoring. Since the detection of the magnetic field by the Hall sensor depends on the characteristics of the magnetic sensitive material, there may be certain errors or false responses. For example, during the use of the electronic cigarette, the swing of the cigarette rod or other factors will cause changes in the magnetic field, thereby causing detection errors; or when there is a magnetic object around the electronic cigarette, the changing magnetic field may cause the Hall sensor to respond falsely during the process of approaching or leaving.

[0063] like Figure 1 As shown, the present invention provides an aerosol-generating article 10. The aerosol-generating article 10 can be removably coupled to an aerosol-generating device 20. The aerosol-generating article 10 can be disposable or reusable.

[0064] The aerosol generating article 10 comprises a body 10 , a first detected portion 120 , and a second detected portion 140 . The first detected portion 120 and the second detected portion 140 are spaced apart along the length direction of the body 10 .

[0065] Optionally, the first measured part 120 and the second measured part 140 are configured as magnetic parts or metal parts. The first measured part 120 and the second measured part 140 can be sensed by a Hall sensor.

[0066] In the present invention, the first detected part 120 and the second detected part 140 are used to be sensed by an external structure, so as to determine the position of the body 10. By using two detected parts, the sensing points of the position of the aerosol generating article 10 can be increased, thereby improving the accuracy of position detection. Compared with the design using only a single detected part, this dual sensing design can more accurately determine the position of the aerosol generating article 10 and reduce the possibility of misjudgment and misresponse.

[0067] In some embodiments of the present invention, the first measured part 120 is disposed at the end of the body 10, and the second measured part 140 is disposed at the middle of the body 10. When the body 10 is pulled out, the second measured part 140 and the first measured part 120 pass through the Hall sensor in sequence, and the Hall sensor senses the change of the magnetic field of the second measured part 140, and determines that the body 10 leaves the bottom of the aerosol generating device 20, and the Hall sensor senses the change of the magnetic field of the first measured part 120 to a predetermined value, and determines that the body 10 leaves the aerosol generating device 20.

[0068] In some embodiments of the present invention, the body 10 is constructed as a hollow cylindrical structure. The body 10 is provided with a smoking section 110 , an airway section 130 and a filter section 150 .

[0069] The smoking section 110 contains a substrate, which is capable of generating an aerosol. Optionally, the substrate generates an aerosol by heating.

[0070] The substrate may comprise a solid aerosol-forming substrate. The solid aerosol-forming substrate may comprise a tobacco-containing material containing volatile tobacco flavour compounds which are released from the aerosol-forming substrate upon heating. The solid aerosol-forming substrate may comprise a non-tobacco material.

[0071] The substrate may comprise a liquid aerosol-forming substrate.The liquid aerosol-forming substrate may comprise a liquid containing tobacco material containing volatile tobacco flavour components, and may also be a liquid containing non-tobacco material.

[0072] The smoking section 110 includes a first end 111 and a second end 112 that are oppositely arranged. The first measured portion 120 is connected to the second end 112. The airway section 130 is arranged at the first end 111. A first channel 131 for aerosol to pass through is formed in the airway section 130. Optionally, when in use, the airway section 130 is closer to the user's mouth than the smoking section 110. The aerosol generated by the smoking section 110 passes through the airway section 130 and enters the user's mouth. The airway section 130 can effectively cool the passing aerosol, and when the aerosol enters the user's mouth, the temperature is more suitable, thereby improving the user's smoking experience.

[0073] In some embodiments of the present invention, the second detected portion 140 is disposed inside the first channel 131, and a second channel 141 is formed inside the second detected portion 140, and the first channel 131 is fluidically connected to the second channel 141. Optionally, the second detected portion 140 may be configured as a porous structure to improve the smoking effect and the uniformity of smoke generation.

[0074] In some other embodiments of the present invention, the second detected portion 140 is disposed outside the first channel 131. Optionally, a groove is disposed outside the body 10 for accommodating the second detected portion 140.

[0075] By configuring the second detected portion 140 , the induction of the detected component 220 is achieved without affecting the smoking effect, and the user experience is good.

[0076] The filter segment 150 is disposed on a side of the airway segment 130 away from the smoking segment 110 , and the filter segment 150 is in fluid communication with the smoking segment 110 .

[0077] A filter element is disposed in the filter segment 150. The filter element may be made of any suitable filter material. Optionally, when in use, the filter segment 150 is closer to the user's mouth than the airway segment 130. The filter segment 150 may be held in the user's mouth. The filter segment 150 may effectively filter harmful substances in the aerosol, such as particulate matter, etc.; the filter segment 150 may also prevent liquid from entering the user's mouth, thereby preventing accidental inhalation of liquid or spillage of tobacco oil, which may cause discomfort or danger.

[0078] like Figure 2-Figure 3 As shown, the utility model provides an electronic cigarette. The electronic cigarette comprises the above-mentioned aerosol generating product 10 and an aerosol generating device 20. The aerosol generating product 10 is pluggably connected to the aerosol generating device 20.

[0079] In some embodiments of the present invention, the aerosol generating device 20 includes a base 210 and a detection member 220. A receiving cavity 211 is formed in the base 210, and the receiving cavity 211 is used to removably receive the aerosol generating product 10. The detection member 220 is used to sense the first detected part 120 and the second detected part 140. The detection member 220 can accurately sense whether the aerosol generating product 10 has been inserted into the base 210 and determine its position and state. By sensing the detected part, the system can perform corresponding control and monitoring.

[0080] Optionally, the detection member 220 is a Hall sensor. The Hall sensor can realize non-contact magnetic field detection and sense the change of the magnetic field of the measured object without physical contact. The detection method of the Hall sensor in combination with the magnetic part or the metal part is highly sensitive and accurate, while reducing the friction and wear between the measured object and the measured object, thereby extending the service life of the sensor. The detection member 220 can quickly sense the state changes of the first measured part 120 and the second measured part 140, so that the insertion or removal of the aerosol generating product 10 can be monitored in real time, and timely feedback is given to the controller 240 for corresponding control.

[0081] The base 210 is configured as a hollow cylindrical structure and has a receiving cavity 211 with one end open. The aerosol generating article 10 can be inserted into the receiving cavity 211 .

[0082] The electronic cigarette is also provided with a heating element 230. The heating element 230 is arranged inside or outside the accommodating cavity 211, and the heating element 230 is used to heat the substrate.

[0083] When the aerosol generating article 10 is fully inserted into the base 210, the heating element 230 corresponds to the substrate. When the heating element 230 directly corresponds to the smoking section 110, the heating efficiency can be maximized, the heating energy is directly concentrated on the part that needs to be heated, and the energy loss during the transmission process is reduced.

[0084] Optionally, the heating element 230 adopts electromagnetic heating, that is, the heating element 230 is an induction coil. Compared with the traditional resistance wire heating method, the induction coil can generate a uniform magnetic field in a larger range, thereby achieving more uniform heating.

[0085] When the aerosol generating article 10 is fully inserted into the base 210, the first measured portion 120 is offset from the heating element 230. This prevents the heating element 230 from interfering with or damaging the first measured portion 120. The first measured portion 120 is not in the magnetic field generated by the induction coil, and the first measured portion 120 does not generate heat as the induction coil generates the magnetic field.

[0086] Optionally, a side wall of the base 210 is provided with an interlayer, and the heating element 230 is disposed in the interlayer, that is, the heating element 230 is sleeved on the cavity wall of the accommodating cavity 211 .

[0087] Optionally, the base 210 is provided with an expansion chamber 250 at one side of the opening, and the detection member 220 is disposed on a side wall of the expansion chamber 250. The detection member 220 is disposed opposite to the first detected portion 120.

[0088] In the process of inserting the aerosol generating product 10 into the base 210, the first measured part 120 and the second measured part 140 can pass through the detection part 220 in sequence; in the process of pulling out the aerosol generating product 10 from the base 210, the second measured part 140 and the first measured part 120 can pass through the detection part 220 in sequence. By designing the detection part 220 in sequence, misoperation can be effectively prevented. Only in the correct order, that is, inserting the first measured part 120 first and then inserting the second measured part 140, or pulling out the second measured part 140 first and then pulling out the first measured part 120, the system will recognize and respond. This can avoid unnecessary interference or errors caused by misoperation. By accurately sensing the insertion and removal actions and performing corresponding controls as needed, the safety of the device can be enhanced. For example, in an electronic cigarette, the heating process can only be started after the cartridge is correctly installed, avoiding dry burning or other safety issues caused by the failure to insert the cartridge.

[0089] like Figure 4 As shown, the electronic cigarette is provided with a controller 240. The controller 240 is electrically connected to the detection element 220 and the heating element 230, thereby realizing intelligent control of the operation state of the electronic cigarette to ensure the correct use and safety of the device. The specific control logic of the electronic cigarette is as follows:

[0090] S1, sensing stage: When the aerosol generating article 10 begins to be inserted into the base 210, the first detected portion 120 first passes through the detection member 220. The detection member 220 senses a specific signal (such as a magnetic field change) of the first detected portion 120 and sends a signal to the controller 240, indicating that the insertion action has begun.

[0091] S2, confirmation stage: As the aerosol generating article 10 continues to be inserted, the second detected portion 140 passes through the detection member 220. The detection member 220 senses again and sends a signal to the controller 240, indicating that the aerosol generating article 10 has been fully inserted into place.

[0092] S3, start the heating process: Only after the first detected part 120 and the second detected part 140 pass through the detection element 220 in sequence and the controller 240 receives two signals, the controller 240 confirms that the aerosol generating article 10 has been correctly installed. At this time, the controller 240 unlocks the control of the heating element 230, and the user sends a heating signal to the controller 240, and the controller 240 controls the heating element 230 to start the heating process to generate aerosol.

[0093] S4. Unplugging monitoring and safety protection: When the aerosol generating article 10 is unplugged, the order is reversed—first the second detected portion 140 passes through the detection member 220 , and then the first detected portion 120 .

[0094] S41, when the second detected part 140 passes through the detection element 220, the controller 240 controls the heating element 230 to be locked. At this time, even if the user sends a heating signal to the controller 240, the heating element 230 will not start the heating process.

[0095] S42, the second detected part 140 and the first detected part 120 pass through the detection member 220 in sequence, and the controller 240 receives signals generated by the pulling-out action in sequence, and determines that the aerosol generating product 10 is completely pulled out.

[0096] The electronic cigarette can also realize the following functions: if an abnormal sequence is detected at any time (such as only one detected part passes), the controller 240 will not start the heating process and enter the standby or safety mode to avoid dry burning or other potential risks. It may also remind the user of wrong operation through indicator lights, sounds or other means.

[0097] like Figure 5As shown, the detection element 220 responds twice during the insertion and removal process of the aerosol generating product 10, which greatly reduces the detection error and also avoids the detection element 220 from responding incorrectly due to the change of the magnetic field caused by the swing of the aerosol generating product 10 or other factors. Even if there are other magnetic parts, metal parts, etc. around the electronic cigarette, which causes the detection element 220 to respond incorrectly once, it still does not meet the condition of responding twice and will not cause any impact.
