Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0032] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0033] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0034] Heated non-combustible devices use a heating-non-combustible method to heat aerosol-generating products to atomize them and produce aerosols. For example, aerosol-generating products can be heated and atomized to produce aerosols for users to inhale. One heating method of heated non-combustible devices involves heating an airflow and then having the heated airflow flow upwards over the aerosol-generating product. During this process, oxygen is mixed in the airflow, which can oxidize some or some components of the aerosol-generating product, producing harmful substances.

[0035] To address this issue and prevent the generation of harmful substances, a non-combustible heating device using the Natural Smoke Cigarettes (NSCs) method is designed. The aerosol-generating product is heated within a heating chamber, and the generated aerosol enters a cooling section. There, it mixes with the incoming airflow and cools down before being discharged through a filter section. To prevent or reduce the entry of oxygen into the heating chamber, a tight seal between the aerosol-generating product and the heating chamber must be ensured.

[0036] In related technologies, sealing is achieved by bonding the aerosol generating product to the heating chamber. However, improper installation can easily lead to a decrease in sealing effectiveness and unstable sealing results. To improve this, sealing rings are installed between the aerosol generating product and the heating chamber, or the two are connected by threads. However, these sealing methods can loosen over long-term use due to material aging or thermal expansion and contraction caused by temperature changes, resulting in gaps and poor reliability.

[0037] To address the aforementioned issues, this application provides a heat-not-burning device and a heat-not-burning system to improve the reliability of the seal between the aerosol-generating product and the heating chamber.

[0038] In the following embodiments, the heated non-combustible device is an electronic cigarette as an example, and the heating chamber is the accommodating chamber in the following embodiments.

[0039] See Figures 1-4As shown, the heated non-combustible device provided in this application includes a housing structure 10, a heating component 20, and a fluid-actuated seal 30.

[0040] The accommodating structure 10 is provided with an accommodating cavity 11, which is configured to accommodate the aerosol generating article 100. The accommodating structure 10 can be cup-shaped, and the inner cavity of the cup-shaped accommodating structure 10 is formed as the accommodating cavity 11, so that the accommodating cavity 11 is cup-shaped. The accommodating cavity 11 also has an accommodating opening 111 formed on the accommodating structure 10, and the aerosol generating article 100 can be placed inside the accommodating cavity 11 through the accommodating opening 111 of the cup-shaped accommodating cavity 11.

[0041] In some embodiments, the aerosol generating article 100 may be inserted into the receiving cavity 11 via the receiving port 111 in an insert manner, wherein the radial dimension of the receiving cavity 11 shall be adapted to the radial dimension of the aerosol generating article 100.

[0042] The heating component 20 is connected to the housing structure 10 and is configured to heat the aerosol generating article 100 housed in the housing cavity 11.

[0043] In particular, the heating component 20 can heat the aerosol generating product 100 in a non-combustible manner, such as by using hot air flow heating, circumferential heating, or central heating, so that the aerosol generating product 100 generates aerosol after being heated.

[0044] In some embodiments of this application, the accommodating cavity 11 of the accommodating structure 10 can be formed on the heating component 20, so that the aerosol generating article 100 is circumferentially heated by the heating component 20, making the accommodating structure 10 and the heating component 20 an integral structure, reducing the product installation space and enabling the product to be integrated and miniaturized. Of course, the heating component 20 can also be installed in the accommodating cavity 11, for example, using a heating mesh installed on the cavity wall of the accommodating cavity 11 to circumferentially heat the aerosol generating article 100. Of course, for the heating component 20 disposed on the cavity wall of the accommodating cavity 11, the cavity wall of the accommodating cavity 11 above the heating component 20 should be sealed to the aerosol generating article 100 to prevent gas from entering. The heating component 20 can also be a needle-shaped or rod-shaped heating element, which is inserted into the center of the aerosol generating article 100 housed in the accommodating cavity 11 to centrally heat the aerosol generating article 100.

[0045] In this embodiment, the heating component 20 preferably adopts a circumferential heating method. It can be set on the cavity wall of the accommodating cavity 11 or on the outer periphery of the accommodating structure 10 to achieve the effect of oxygen-free heating.

[0046] The heating element 20 heats the aerosol-generating product 100 circumferentially using an oxygen-free heating method to avoid the generation of harmful substances. See also Figure 5 As shown, the aerosol generating product 100 includes a matrix section 101, a sealing section 102, a cooling section 103, a filtering section 104, and an outer wrapping layer 105. The matrix section 101, sealing section 102, cooling section 103, and filtering section 104 are wrapped by the outer wrapping layer 105, which is made of paper. The matrix section 101 is located between the sealing section 102 and the cooling section 103, and the cooling section 103 is located between the filtering section 104 and the matrix section 101. The matrix section 101 is an aerosol matrix that can generate aerosols when heated. In practical applications, the matrix section 101 is placed in the accommodating cavity 11. The sealing section 102 can prevent airflow from entering from the bottom of the aerosol generating product 100, thereby achieving oxygen-free heating. The cooling section 103 is also provided with a cooling channel 1031 running through its inner cavity. The two ends of the cooling channel 1031 are connected to the substrate section 101 and the filter section 104 respectively. Multiple air inlets 1032 are also provided through the channel wall of the cooling channel 1031, so that the cooling channel 1031 is connected to the outside through the air inlets 1032. The filter section 104 is made of fiber cotton material to fully filter particulate matter.

[0047] In practical applications, the user draws air through the filter section 104, and outside air enters the cooling channel 1031 through the air inlet 1032, creating a negative pressure in the substrate section 101 and a pressure difference relative to the cooling channel 1031. Simultaneously, the heating component 20 is activated to heat the substrate section 101 to generate an aerosol. Under the pressure difference, the aerosol flows into the cooling channel 1031 and mixes with the outside air entering through the air inlet 1032, achieving the cooling purpose. The cooled aerosol is then filtered through the filter section 104 and output for the user's use.

[0048] In practical use, it is only necessary to ensure that the matrix section 101 is located within the accommodating cavity 11. The portion of the aerosol generating article 100 above the matrix section 101 is sealed to the cavity wall of the accommodating cavity 11. Therefore, the sealing section 102 is not required in the aerosol generating article 100. However, when the matrix in the matrix section 101 is granular or filamentous, it needs to be sealed by the sealing section 102 to prevent matrix leakage.

[0049] After placing the aerosol generating article 100 into the receiving cavity 11, it is necessary to ensure the sealing between the outer wall of the aerosol generating article 100 and the cavity wall of the receiving cavity 11 to prevent air from entering the receiving cavity 11. To this end, this application employs a fluid-actuated seal 30, which is connected to the cavity wall of the receiving cavity 11 around its axis. The fluid-actuated seal 30 has a pressure chamber 31, and is configured to produce radial expansion changes (e.g., when the pressure of the fluid medium in the pressure chamber 31 is changed) when the pressure is altered. Figure 3 and Figure 4As shown), a dynamic seal is created between the cavity wall of the accommodating cavity 11 and the outer surface of the aerosol generating article 100 housed in the accommodating cavity 11.

[0050] The fluid-actuated seal 30 is an annular sealing structure connected to the cavity wall of the accommodating cavity 11 along the axis surrounding the cavity 11. The internal pressure cavity 31 is also annular in shape. Fluid medium can be injected or filled into the pressure cavity 31 to cause the fluid-actuated seal 30 to expand. During the expansion process, the gap between the cavity wall of the accommodating cavity 11 and the outer surface of the aerosol generating product 100 can be sealed. The radial dimension of the expansion increases with the increase of fluid medium in the pressure cavity 31 and decreases with the decrease of fluid medium in the pressure cavity 31. Therefore, a dynamic sealing effect can be achieved.

[0051] See Figure 6 As shown, the heated non-combustible device provided in this application also includes a fluid medium supply mechanism 70. The fluid medium supply mechanism 70 is in fluid communication with the pressure chamber 31 of the fluid-actuated seal 30. The fluid medium supply mechanism 70 is configured to supply a fluid medium to the pressure chamber 31. For example, the fluid medium supply mechanism 70 injects or fills the pressure chamber 31 with a fluid medium. The fluid medium supply mechanism 70 can use a liquid pump or a pneumatic pump for different media. Of course, in some embodiments, a pneumatic cylinder or a hydraulic cylinder can also be used to provide power to the injection tube structure to achieve the above-mentioned function of injecting the medium. The fluid medium can be one of a liquid medium, a gaseous medium, or a gas-liquid mixture. In this embodiment, a gaseous medium is selected as the fluid medium, for example, air, an inert gas, etc. The fluid-actuated seal 30 expands radially after air is injected into the pressure chamber 31. Conversely, if the fluid medium in the pressure chamber 31 of the fluid-actuated seal 30 is extracted and it retracts, the fluid medium supply mechanism 70 can both inject air into the pressure chamber 31 and extract air from the pressure chamber 31. The fluid medium supply mechanism 70 is preferably an air pump.

[0052] Of course, it is not difficult to understand that when the pressure chamber 31 is not filled with fluid medium, the fluid-actuated seal 30 is in a retracted state (such as...). Figure 1 and Figure 2 As shown), the fluid-actuated seal 30 shrinks in volume, allowing the aerosol-generating article 100 to be smoothly placed into the receiving cavity 11. Then, a fluid medium is injected into the pressure cavity 31 via the fluid medium supply mechanism 70, causing it to expand radially (e.g., ...). Figure 3 and Figure 4 This can create a dynamic sealing effect between the cavity wall of the accommodating cavity 11 and the outer surface of the aerosol generating product 100.

[0053] When the aerosol generating article 100 is placed in the receiving cavity 11, it is positioned within the cavity 11 by the radial expansion of the fluid-actuated seal 30. The magnitude of the radial expansion of the fluid-actuated seal 30 affects the tightness of its positioning. In some embodiments, if the radial dimensions of different aerosol generating articles 100 are different or slightly different, when injecting the same pressure of fluid medium into the pressure chamber 31 to seal the outer surface of the aerosol generating article 100 against the cavity wall of the receiving cavity 11, there is a problem that the aerosol generating article 100 with a smaller radial dimension cannot be completely sealed. For this, see [link to relevant documentation]. Figure 6 As shown, the heating non-combustible device provided in this application further includes a pressure detection element 40 and a pressure regulating element 50. The pressure detection element 40 is configured to be in fluid communication with the pressure chamber 31 of the fluid actuation seal 30 to detect the pressure of the fluid medium in the pressure chamber 31. The pressure regulating element 50 is communicatively connected to the pressure detection element 40 and is configured to adjust the pressure of the fluid medium in the pressure chamber 31 of the fluid actuation seal 30 according to the detection result of the pressure detection element 40.

[0054] In a specific embodiment, the pressure detection element 40 can be a pressure sensor or a fluid sensor, which can detect the pressure of the fluid medium in the pressure chamber 31. It can generate a current pressure from the detected pressure in the pressure chamber 31 and output it to the pressure regulating element 50 via a communication connection. The pressure regulating element 50 can be a microcontroller or a microprocessor. The pressure regulating element 50 can compare the current pressure detected by the pressure detection element 40 in the pressure chamber 31 with a preset pressure to generate an adjustment signal, which is then output to the fluid medium supply mechanism 70 to control the fluid medium supply mechanism 70 to increase or decrease the amount of fluid medium output. The preset pressure is the pressure at which the fluid-actuated sealing element 30 expands and adheres to the outer surface of the aerosol-generated product 100; reliable sealing can be achieved under this preset pressure. However, aerosol generating products 100 with different radial dimensions have the problem of not being able to achieve a complete seal. For example, the aerosol generating product 100 with a smaller radial dimension has a larger gap between itself and the cavity wall of the receiving cavity 11 compared to the aerosol generating product 100 with a standard radial dimension. The aerosol generating product 100 with a standard radial dimension can achieve a sealing effect with the cavity wall of the receiving cavity 11 under a preset pressure in the pressure chamber 31. Conversely, the aerosol generating product 100 with a larger radial dimension requires more fluid medium to make the radial dimension of the fluid-actuated seal 30 larger than that of the aerosol generating product 100 with a standard radial dimension.

[0055] For example, when the pressure detection element 40 detects that the current pressure in the pressure chamber 31 is less than the preset pressure, the pressure regulating element 50 outputs a pressure boosting regulation signal to the fluid medium supply mechanism 70, and the fluid medium supply mechanism 70 increases the amount of fluid medium output according to the pressure boosting regulation signal. Conversely, when the pressure detection element 40 detects that the pressure in the pressure chamber 31 is greater than the preset pressure, the pressure regulating element 50 outputs a pressure reduction regulation signal to the fluid medium supply mechanism 70, and the fluid medium supply mechanism 70 draws water from the pressure chamber 31 according to the pressure reduction regulation signal to reduce the pressure in the pressure chamber 31 to the preset pressure.

[0056] After the aerosol generating article 100 is placed in the receiving cavity 11, the heating component 20 can heat the aerosol generating article 100. To ensure that heating and sealing are performed simultaneously, see [link to relevant documentation]. Figure 7 As shown, the heating non-combustible device provided in this embodiment also includes a heating control component 60, which is communicatively connected to the heating component 20 and the fluid medium supply mechanism 70. The heating control component 60 is configured to be operable to synchronously trigger the fluid actuation seal 30 when the heating component 20 is started.

[0057] In a specific embodiment, the fluid-actuated seal 30 achieves a sealing effect by filling or injecting a gas medium into the pressure chamber 31 through the fluid medium supply mechanism 70 to achieve radial expansion. Therefore, when the heating component 20 is triggered by the heating control component 60 to start heating, the fluid medium supply mechanism 70 is also triggered by the heating control component 60 to start synchronously, so that the matrix section 101 in the aerosol generating product 100 is heated, and the outer surface of the aerosol generating product 100 and the cavity wall of the accommodating cavity 11 are simultaneously sealed, thus preventing air from entering.

[0058] Of course, the process of the heating component 20 generating heat or reaching the heat required to generate aerosol in the matrix section 101 of the aerosol generating article 100 is slow, for example, requiring 3s-5s. Therefore, the heating control component 60 can ensure that the fluid-actuated seal 30 achieves the expansion effect by synchronously triggering the fluid medium supply mechanism 70 during the 3s-5s time of triggering the aerosol of the heating component 20.

[0059] The aforementioned heating control component 60 can be a switch, which can trigger the opening and closing of the heating component 20 and the fluid medium supply mechanism 70 by means of tossing, turning, touching, etc.

[0060] See Figures 1-4As shown, the heating chamber 11 is also provided with a receiving groove 12 on its cavity wall. The receiving groove 12 is arranged around the axis of the heating chamber 11. After the fluid medium is extracted from the pressure chamber 31, the fluid-actuated seal 30 is in a contracted state and at least partially contracted in the receiving groove 12, which facilitates the placement of the aerosol generating product 100 in the receiving chamber 11.

[0061] The fluid-actuated seal 30 can be installed in the receiving groove 12 by adhesive bonding, and generate radial expansion by filling the pressure chamber 31 with fluid medium to protrude out of the receiving groove 12, thereby sealing the outer surface of the aerosol generating product 100 with the cavity wall of the receiving cavity 11.

[0062] In this embodiment, the height of the fluid-actuated seal 30 protruding radially from the cavity wall of the receiving cavity 11 is 0.05mm-0.5mm. For example, after the fluid brake seal 30 is filled into its pressure cavity 31 or expanded by the injected fluid medium, the height of the fluid brake seal 30 protruding radially from the cavity wall of the receiving cavity 11 is 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. The size of its protrusion height is determined according to the size of the gap between the aerosol generating product 100 placed in the receiving cavity 11 and the cavity wall of the receiving cavity 11 and the groove depth of the receiving groove 12, and is not limited here.

[0063] See also Figures 1-4 As shown, the cavity wall of the receiving cavity 11 is provided with a plurality of elastic positioning protrusions 13, which are configured to position the aerosol generating article 100 contained in the receiving cavity 11. The elastic positioning protrusions 13 are interference-fitted with the aerosol generating article 100, which can achieve a coaxial positioning effect with the receiving cavity 11 before the aerosol generating article 100 is sealed by the fluid-actuated seal 30, so as to ensure that the pressure chamber 31 of the fluid-actuated seal 30 can be completely sealed circumferentially after being filled with fluid medium and expanded, thereby improving the sealing effect.

[0064] See Figures 1-4 As shown, the accommodating cavity 11 has an accommodating opening 111 formed on the accommodating structure 10, through which the aerosol generating article 100 can be taken out and put in, and a plurality of elastic protrusions 13 are disposed close to the accommodating opening 111 relative to the fluid-actuated seal 30.

[0065] In this embodiment, a plurality of elastic positioning protrusions 13 are arranged circumferentially around the receiving cavity 11. More specifically, the plurality of elastic positioning protrusions 13 are arranged in a circular array around the axis of the receiving cavity 11 on the cavity wall near the receiving opening 111, so as to provide a uniform positioning force for the aerosol generating product 100.

[0066] In some embodiments, when there are enough elastic positioning protrusions 13 to form a sealing effect between two adjacent positioning protrusions 13, a certain sealing effect can be achieved on the aerosol generating article 100.

[0067] In this embodiment, the height of the elastic positioning protrusion 13 protruding in the radial direction of the accommodating cavity 11 is 0.1mm-1mm, and it retracts elastically when it is in an interference fit with the aerosol generating product 100.

[0068] In this application, the fluid-actuated seal 30 includes an air bladder, the inner cavity of which is formed as a pressure chamber 31. Since it operates in a high-temperature environment, both the air bladder and the elastic positioning protrusion 13 can be made of high-temperature resistant and oxidation-resistant silicone material.

[0069] This application also provides a heat-not-burning system, which includes the heat-not-burning device described in the above embodiments, and further includes an aerosol generating article 100, which is housed in a receiving cavity 11. The structure and features of the heat-not-burning device and the aerosol generating article 100 have been described in the above embodiments and will not be repeated here.

[0070] It should be noted that if the sealing between the accommodating cavity 11 and the aerosol generating product 100 is poor, gas will enter the matrix section 101 from the bottom of the aerosol generating product 100, causing the temperature of the heated matrix section 101 to drop, affecting the heating curve. This will require the heating component 20 to continuously adjust the heating temperature of the matrix section 101, increasing the difficulty of temperature control.

[0071] In the heated non-combustible system provided in this application, the cavity wall of the accommodating cavity 11 and the outer surface of the aerosol generating product 100 are sealed by the fluid-actuated seal 30, which can realize oxygen-free heating, avoid the problem of temperature reduction of the matrix section 101 caused by heating from the bottom of the aerosol generating product 100, and do not affect the heating effect of the heating component 20, significantly reducing the difficulty of temperature control.

[0072] In summary, in the heating non-combustible device and heating non-combustible system provided by this utility model, the fluid-actuated seal expands after the pressure changes in its pressure chamber. During the expansion process, it can seal the gap between the cavity wall of the accommodating cavity and the outer surface of the aerosol generating product, making it less prone to loosening and improving the reliability of the seal.

[0073] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
