For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the embodiment of the present application, "axial direction" is based on the Figure 3 It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] In a first aspect, an embodiment of the present application provides an aerosol generating system, which includes an aerosol generating substrate and an aerosol generating device of any embodiment of the present application, wherein the aerosol generating device has a containing chamber, and the aerosol generating substrate is arranged in the containing chamber, and the heating element of the aerosol generating device is used to heat the aerosol generating substrate.

[0034] The containing chamber provides a containing space for the aerosol generating substrate, and the aerosol generating substrate can be heated by the heating element in the containing chamber to generate aerosol.

[0035] The shape and size of the storage chamber are not limited, as long as they can meet the storage requirements of the aerosol generating substrate.

[0036] like Figures 1 to 4 As shown, in the second aspect, the embodiment of the present application provides an aerosol generating device, which includes a power supply component and a heating component 10 of any embodiment of the present application. The heating component 10 includes a heating element 14, and the power supply component is electrically connected to the heating element 14.

[0037] The power supply assembly is mainly used to supply power to the heating element 14 and control the opening or closing of the entire aerosol generating device. The heating element 14 can heat the aerosol generating substrate after power is turned on to generate aerosol for the user to take. The aerosol generating substrate includes but is not limited to materials used for medical treatment, health preservation, health, beauty and other purposes. For example, the aerosol generating substrate includes but is not limited to medicines, materials containing nicotine or materials not containing nicotine, etc.

[0038] It should be noted that the specific type of the aerosol generating device provided in the embodiments of the present application is not limited. For example, the aerosol generating device can be a medical atomizing device, an air humidifier, or an atomizing device such as an electronic cigarette.

[0039] Thirdly, Figures 1 to 4 As shown, an embodiment of the present application provides a heating component for an aerosol generating device, wherein the heating component 10 includes a first support 11, a second support 12, a shell 13 and a heating element 14; the first support 11 has a first vent hole 11a; opposite ends of the shell 13 are sealedly connected to the first support 11 and the second support 12 respectively, and the shell 13, the first support 11 and the second support 12 define a mounting cavity 10a; the heating element 14 has a heating cavity 14a inside, the heating element 14 is arranged in the mounting cavity 10a, one end of the heating cavity 14a is connected to the outside through the first vent hole 11a, and the heating element 14 is used to heat the aerosol generating matrix.

[0040] After the heating assembly 10 is used in the aerosol generating device, the heating chamber 14a can be understood as a storage chamber of the aerosol generating device. The heating chamber 14a is used to accommodate the aerosol generating substrate. It should be noted that the form of the aerosol generating substrate is not limited, for example, it can be solid. The aerosol generating substrate can include tobacco material.

[0041] The first vent hole 11a can be used for air intake or air exhaust of the heating chamber 14a. For example, in some embodiments, after the aerosol generating substrate is disposed in the heating chamber 14a, there is a gap between the aerosol generating substrate and the hole wall of the first vent hole 11a, and the external airflow enters the heating chamber 14a through the gap and reaches the end of the heating chamber 14a away from the first vent hole 11a, and the external airflow then flows through the inside of the aerosol generating substrate toward the first vent hole 11a, and carries the aerosol generated by the aerosol generating substrate out of the heating chamber 14a.

[0042] In some other embodiments, the second support 12 has a second vent hole 12a, one of the first vent hole 11a and the second vent hole 12a is used for air intake of the heating chamber 14a, and the other is used for air discharge of the heating chamber 14a. For example, the first vent hole 11a is an air outlet, and the second vent hole 12a is an air inlet. When the aerosol generating device is in use, the external airflow enters the heating chamber 14a through the second vent hole 12a, and carries the aerosol generated in the heating chamber 14a out of the heating chamber 14a through the first vent hole 11a, and the user can take the aerosol through the first vent hole 11a.

[0043] The shape of the housing 13 is not limited. Figure 1 As shown, the housing 13 is a cylindrical structure. The cylindrical structure can be a round cylinder or a square cylinder.

[0044] The opposite ends of the housing 13 are sealedly connected to the first support 11 and the second support 12 respectively.

[0045] It should be noted that the sealed connection does not necessarily require absolute sealing, for example, the sealed connection between the housing 13 and the first support 11 means that the housing 13 and the first support 11 have good airtightness after being connected. The sealed connection between the housing 13 and the second support 12 also needs to be understood in this way.

[0046] The installation cavity 10 a has good sealing performance both at the connection between the housing 13 and the first support 11 and at the connection between the housing 13 and the second support 12 .

[0047] After the heating element 14 is disposed in the installation cavity 10 a , the cavity wall of the installation cavity 10 a is equivalent to forming a certain protective effect on the heating element 14 .

[0048] In the related art, the opposite ends of the heating element are respectively connected to the first support and the second support by using sealing silicone. When the heating component is exposed to high temperature and acid-base environment for a long time, the sealing silicone is prone to aging and hardening, thereby losing its sealing effect, resulting in sealing failure at the connection between the heating chamber and the first support or at the connection between the heating chamber and the second support, thereby affecting the reliability and service life of the heating component.

[0049] The heating component provided in the embodiment of the present application is defined by the outer shell 13, the first support 11 and the second support 12 to form an installation cavity 10a, and the heating element 14 is arranged in the installation cavity 10a, that is, the connection between the heating element 14 and the first support 11 and the connection between the heating element 14 and the second support 12 are both located in the installation cavity 10a. Since the opposite ends of the outer shell 13 are sealed with the first support 11 and the second support 12 respectively, the connection between the outer shell 13 and the first support 11 and the connection between the outer shell 13 and the second support 12 both have good sealing properties. Under the protection of the cavity wall of the installation cavity 10a, the heating element 14 is not easily affected by high temperature and acid-base environment, which is beneficial to improve the sealing performance of the heating element 14 in high temperature and acid-base environment, reduce the risk of aerosol generated in the heating cavity 14a leaking from the heating component 10, and improve the reliability and service life of the heating component 10.

[0050] It should be noted that the sealing connection method between the housing 13 and the first support 11 or the second support 12 is not limited. For example, in some embodiments, the first support 11 is welded to the housing 13. The first support 11 and the housing 13 are sealed by welding, and the first support 11 and the housing 13 have better sealing performance. At the same time, the welding sealing method has stronger corrosion resistance, which further improves the sealing performance of the heating component 10 in an acidic and alkaline environment.

[0051] In some embodiments, the second support 12 is welded to the housing 13. The second support 12 and the housing 13 are welded and sealed, and the second support 12 and the housing 13 also have better sealing performance. At the same time, the welding sealing method has stronger corrosion resistance, which further improves the sealing performance of the heating component 10 in an acid-base environment.

[0052] like Figure 3 and Figure 4 As shown, in some embodiments, the housing 13 has a mounting channel 13a that passes through opposite ends of the housing 13, at least a portion of the second support 12 is disposed in the mounting channel 13a, and sealant is filled between the second support 12 and the side wall of the mounting channel 13a.

[0053] It should be noted that, in this embodiment, a mounting cavity 10 a is defined between the side wall of the mounting channel 13 a and the first support 11 and the second support 12 .

[0054] Specifically, the gap C may be filled with sealant, and the sealant forms a solid-like structure after cooling and solidifying.

[0055] The type of sealant is not limited. For example, in some embodiments, the sealant can be hot melt glue, which is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, it is easy to package, transport, store, and is solvent-free, pollution-free, and non-toxic, which is beneficial to human health.

[0056] Of course, in other embodiments, the sealant may also be glass glue or the like.

[0057] By filling the space between the second support 12 and the side wall of the installation channel 13a with sealant, the sealing performance between the second support 12 and the housing 13 can be further improved, thereby reducing the risk of aerosol backflow and corrosion of the power supply components.

[0058] The installation channel 13a can facilitate the connection between the second support 12 and the housing 13. At the same time, a gap C is formed between the second support 12 and the installation channel 13a, so that welding and sealing can be easily achieved between the two.

[0059] At least part of the first support 11 may also be disposed in the installation channel 13a, so that the first support 11 and the housing 13 are connected easily. Meanwhile, the gap between the first support 11 and the installation channel 13a can be conveniently welded and sealed.

[0060] like Figure 3 As shown, in some embodiments, one end of the heating element 14 is sealed and connected to the first support 11 .

[0061] In this embodiment, one end of the heating element 14 connected to the first support 11 is equivalent to achieving double sealing. The heating element 14 and the first support 11 are sealed and connected to form a first seal, and the outer shell 13 and the first support 11 are sealed and connected to form a second seal. In this way, it is further ensured that the aerosol generated in the heating chamber 14a will not leak out from the heating component 10.

[0062] It should be noted that the manner in which the heating element 14 is sealed and connected to the first support 11 is not limited. Figure 3 As shown, in some embodiments, the heating assembly 10 also includes a first seal 15 sleeved on the heating element 14, a first mounting groove 11b is provided on the first support 11, one end of the heating element 14 is provided in the first mounting groove 11b, and the first seal 15 is sealed with the groove wall of the first mounting groove 11b.

[0063] One end of the heating element 14 is disposed in the first mounting groove 11 b . The first mounting groove 11 b can facilitate the connection between the heating element 14 and the first support 11 . Meanwhile, the first mounting groove 11 b also has a certain limiting effect on one end of the heating element 14 .

[0064] The shape of the first mounting groove 11 b is not limited, and it can be a shape matching the side wall of the heating element 14 .

[0065] The material of the first sealing member 15 is not limited. For example, it can be silica gel, etc. The first sealing member 15 made of silica gel is not easy to separate harmful substances when heated, which is beneficial to human health.

[0066] The first sealing member 15 and the groove wall of the first installation groove 11 b can be sealed by interference fit, thereby improving the sealing performance of the connection between the heating element 14 and the first installation groove 11 b.

[0067] It should be noted that the first mounting groove 11 b and the first ventilation hole 11 a are arranged along the axial direction of the heating element 14 and are in communication with each other.

[0068] The diameter of the first mounting groove 11b near the first vent hole 11a is larger than the diameter of the first vent hole 11a near the first mounting groove 11b, that is, a step surface facing the heating element 14 is formed at the connection between the first mounting groove 11b and the first vent hole 11a, and this step surface can limit the heating element 14 axially.

[0069] like Figure 3 As shown, in some embodiments, along the direction from the first support 11 to the second support 12, the diameter of the first installation groove 11b and the thickness of the first sealing member 15 are gradually increased.

[0070] In the related art, generally, a first seal is first arranged in a first mounting groove, and then the heating element is inserted into the inner ring of the first seal. However, in the process of inserting the heating element into the inner ring of the first seal, the heating element can easily damage the inner ring of the first seal, especially the heating element with a flared structure, which is more likely to damage the inner ring of the first seal, thereby resulting in low production efficiency of the heating component and poor sealing performance.

[0071] In the heating component 10 of this embodiment, the first seal 15 can be sleeved on the heating element 14, and the first installation groove 11b is designed to be expanded. The expansion direction of the first installation groove 11b is opposite to the installation direction of the heating element 14. When the heating element 14 carries the first seal 15 and is installed in the first installation groove 11b, the size of the first installation groove 11b gradually shrinks, thereby reducing the possibility of the first seal 15 being damaged. The first seal 15 has a better sealing effect between the heating element 14 and the groove wall of the first installation groove 11b. At the same time, the heating component 10 of this structure is easier to assemble, thereby improving production efficiency.

[0072] The thickness dimension change relationship of the first sealing member 15 is similar to the diameter dimension change relationship of the first mounting groove 11b. Thus, after the heating component 10 is assembled, the gap between the heating element 14 and the groove wall of the first mounting groove 11b can basically be sealed by the first sealing member 15, thereby improving the sealing performance of the heating component 10.

[0073] In addition, after the gap between the heating element 14 and the groove wall of the first installation groove 11b is basically filled with the first sealing member 15, the heating element 14 is not easy to shake in the first installation groove 11b, thus improving the installation stability of the heating element 14 in the first installation groove 11b.

[0074] like Figure 3 and Figure 4 As shown, in some embodiments, the other end of the heating element 14 is sealed and connected to the second support 12 .

[0075] In this embodiment, the end where the heating element 14 is connected to the second support 12 is also equivalent to achieving double sealing. The heating element 14 and the second support 12 are sealed to form a first seal, and the outer shell 13 and the second support 12 are sealed to form a second seal. In this way, it is further ensured that the aerosol generated in the heating chamber 14a will not leak out from the heating component 10.

[0076] It should be noted that the sealing connection between the heating element 14 and the second support 12 is also not limited. Figure 3 and Figure 4As shown, in some embodiments, the heating assembly 10 also includes a second sealing member 16 sleeved on the heating element 14, a second mounting groove 12b is provided on the second support 12, the other end of the heating element 14 is provided in the second mounting groove 12b, and the second sealing member 16 is sealed with the groove wall of the second mounting groove 12b.

[0077] The other end of the heating element 14 is disposed in the second mounting groove 12 b. The second mounting groove 12 b can facilitate the connection between the heating element 14 and the second support 12 . Meanwhile, the second mounting groove 12 b also has a certain limiting effect on the heating element 14 .

[0078] The shape of the second mounting groove 12 b is also not limited, and it can be a shape that matches the side wall of the heating element 14 .

[0079] The material of the second sealing member 16 is not limited. For example, it can be silica gel, etc. The second sealing member 16 made of silica gel is not easy to separate harmful substances when heated, which is beneficial to human health.

[0080] The second sealing member 16 and the groove wall of the second installation groove 12b can be sealed by interference fit, thereby improving the sealing performance of the connection between the heating element 14 and the second installation groove 12b.

[0081] It should be noted that the second mounting groove 12 b and the second vent hole 12 a are arranged along the axial direction of the heating element 14 and are in communication with each other.

[0082] The diameter of the second mounting groove 12b near the second vent hole 12a is larger than the diameter of the second vent hole 12a near the second mounting groove 12b, that is, a step surface facing the heating element 14 is formed at the connection between the second mounting groove 12b and the second vent hole 12a, and this step surface can limit the heating element 14 axially.

[0083] like Figure 2 As shown, in some embodiments, a wire groove 12c is provided on the side wall of the second support 12, and the wire groove 12c extends from the first support 11 to the second support 12, and the wire groove 12c is used for routing the heating element 14. In this way, the silver wire of the heating element 14 is conveniently electrically connected to the power supply assembly.

[0084] like Figures 2 to 4 As shown, in some embodiments, the wire groove 12c is filled with sealant.

[0085] The type of sealant is not limited, and may be, for example, glass glue, hot melt glue, etc.

[0086] Specifically, after the wires are routed in the wire groove 12c, the wires may not occupy the entire space in the wire groove 12c, and the wire groove 12c is further filled with sealant, thereby improving the sealing performance of the wire groove 12c.

[0087] like Figures 2 to 4 As shown, in some embodiments, the wire groove 12 c is disposed on the outer side wall of the second support 12 .

[0088] The wire groove 12c is located on the outer side wall of the second support 12, that is, located on the outer side of the second support 12. In this way, during the wiring of the heating element 14, it is convenient for operators to operate.

[0089] In addition, when the second vent hole 12a is disposed inside the second support 12, the wire groove 12c is disposed on the outer wall of the second support 12, and the wire groove 12c and the second vent hole 12a can be independent of each other and will not affect each other.
