Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to a heating component and an atomizing device. Background Technology

[0002] In existing technologies, the multi-layer sealing structure in atomizing devices exhibits poor sealing performance at the heating expansion chamber. Furthermore, the fixing method between the expansion chamber and the heating tube is a simple overlap.

[0035] A. First direction. Detailed Implementation

[0036] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 The heating assembly 100 according to an embodiment of the present invention includes: a heating structure 10, a support structure 20 and a sealing structure 30, and the heating assembly 100 has a first direction.

[0037] Specifically, such as Figures 1-4 As shown, the heating structure 10 cooperates with the support structure 20; the sealing structure 30 is disposed between the heating structure 10 and the support structure 20, and the sealing structure 30 includes multiple sealing elements, which are spaced apart.

[0038] Combination Figures 1-4The heating assembly 100 is suitable for use in an atomizing device. The heating structure 10 operates by providing the necessary heat during the use of the atomizing device, heating the liquid in the atomizing device to an evaporative state, thereby generating inhalable vapor. The support structure 20 supports the heating structure 10 and ensures its positional stability during operation. The sealing structure 30 is located between the heating structure 10 and the support structure 20 to prevent smoke, condensate, or other contaminants from entering the interior of the atomizing device. The sealing structure 30 includes multiple seals arranged at intervals along different positions of the heating assembly 100 in a first direction, forming a multi-layered sealing barrier.

[0039] According to the heating assembly 100 of this utility model embodiment, the sealing structure 30 of the heating assembly 100 includes multiple sealing elements. These multiple sealing elements form a multi-layer sealing barrier, improving the overall sealing performance of the heating assembly 100, ensuring smooth flow of flue gas without leakage, effectively preventing flue gas generated by the atomizing device from leaking into the internal structure of the atomizing device, protecting internal components from corrosion by flue gas and other condensates, reducing potential safety hazards, and extending the service life of the atomizing device. Different locations of the heating assembly 100 are affected to varying degrees by the impact and corrosion of high-temperature flue gas. The placement of multiple sealing elements at different locations can improve the sealing effect of the heating assembly 100 while reducing production costs.

[0040] According to some embodiments of this utility model, such as Figures 1-4 As shown, the heating structure 10 includes a heating tube 11 and an expansion member 13, the expansion member 13 and the heating tube 11 are arranged along the axial direction of the heating tube 11, at least one of the plurality of seals is disposed between the heating tube 11 and the support structure 20, and at least one of the plurality of seals is disposed between the expansion member 13 and the support structure 20.

[0041] The heating tube 11 extends along a first direction of the heating assembly 100. An air passage is formed inside the heating tube 11, through which the liquid in the atomizing device flows and is heated to an evaporating state via the heating tube 11. An expansion member 13 is disposed at one end of the heating tube 11 along the first direction. The expansion member 13 is used to absorb or buffer the expansion or contraction stress generated by the heating tube 11 when the temperature changes, thereby protecting the heating tube 11 and the entire assembly from damage.

[0042] Therefore, the design of the expansion element 13 can effectively absorb the stress generated during the heating process, preventing the heating tube 11 from being damaged due to thermal expansion, thereby improving the overall stability and reliability of the heating assembly 100. By setting seals between the heating tube 11 and the support structure 20, and between the expansion element 13 and the support structure 20, the sealing performance of the heating assembly 100 can be significantly improved, ensuring smooth flow of flue gas without leakage. The reasonable distribution of seals can effectively prevent condensate and flue gas from corroding internal components, reducing the failure rate and extending the service life of the atomizing device.

[0043] According to some embodiments of this utility model, such as Figures 1-4 As shown, the support structure 20 includes: a first support 21 and a second support 25. The first support 21 is located on the outer periphery of the connection between the heating tube 11 and the expansion member 13. The second support 25 is located on the outer periphery of the heating tube 11 at the end away from the expansion member 13. At least one of the plurality of seals is located between the expansion member 13 and the first support 21. At least one of the plurality of seals is located between the heating tube 11 and the first support 21 and between the heating tube 11 and the second support 25.

[0044] An expansion member 13 is disposed at one end of the heating tube 11 along the first direction, and a first bracket 21 is sleeved on one end of the heating tube 11 along the first direction and on the outer periphery of the expansion member 13. A second bracket 25 is disposed at the other end of the heating tube 11 along the first direction, and the second bracket 25 is sleeved on the outer periphery of the other end of the heating tube 11 along the first direction.

[0045] Therefore, the first bracket 21 is used to fix and support the heating tube 11 and the expansion member 13, and the second bracket 25 is used to fix and support the heating tube 11. The design of the first bracket 21 and the second bracket 25 makes the position of the heating tube 11 and the expansion member 13 more stable in the whole assembly, reducing the risk of displacement due to vibration or thermal expansion. At least one seal is located between the expansion member 13 and the first bracket 21. These seals can effectively prevent flue gas or condensate from entering the interior through the gap between the expansion member 13 and the first bracket 21. At least one seal is respectively provided between the heating tube 11 and the first bracket 21 and the second bracket 25. These seals ensure the sealing between the heating tube 11 and the bracket structure 20, preventing flue gas or condensate from seeping from these parts. Multiple seals are distributed in different positions, forming multiple sealing barriers, which greatly improves the sealing performance of the heating assembly 100 and ensures that flue gas does not leak into the internal structure of the atomizing device.

[0046] According to some embodiments of this utility model, such as Figure 3 As shown, the plurality of sealing elements include: a first sealing element 31, which is disposed between the expansion member 13 and the first bracket 21; a first mounting groove 14 is formed on the outer peripheral wall of the expansion member 13, which extends circumferentially along the heating tube 11, and the first sealing element 31 is disposed in the first mounting groove 14, and the first sealing element 31 abuts against the first mounting groove 14 and the first bracket 21.

[0047] The first mounting groove 14 extends circumferentially along the expansion member 13. The first mounting groove 14 is formed by a radial recess into at least a portion of the outer peripheral wall of the expansion member 13, towards the center. The first sealing member 31 is embedded and fitted within the first mounting groove 14. The first sealing member 31 is disposed between the outer peripheral wall of the expansion member 13 and the inner peripheral wall of the first bracket 21. The first sealing member 31 is adapted to be in close contact with the outer peripheral wall of the expansion member 13 and the inner peripheral wall of the first bracket 21 adjacent to the expansion member 13, forming an effective sealing barrier.

[0048] Therefore, the first seal 31 can effectively prevent flue gas or condensate from seeping into the heating assembly 100 through the gap between the expansion member 13 and the first bracket 21, ensuring smooth flue gas flow without leakage. The first mounting groove 14 is suitable for accommodating the first seal 31, ensuring that the first seal 31 can be evenly distributed and tightly fitted between the expansion member 13 and the first bracket 21. The setting of the first mounting groove 14 can also ensure the correct assembly and installation stability of the first seal 31, avoid poor sealing caused by improper installation, and improve the overall reliability of the heating assembly 100.

[0049] According to some embodiments of this utility model, such as Figure 3 As shown, the first bracket 21 has a first support portion 22, which is located on the side of the first bracket 21 adjacent to the expansion member 13. The side wall of the first mounting groove 14 adjacent to the heating tube 11 abuts against the first support portion 22.

[0050] The first support portion 22 extends radially toward the side where the expansion member 13 is located along the first bracket 21. The first support portion 22 is adapted to abut against the side wall of the first mounting groove 14 adjacent to the heating tube 11 along the first direction, that is, the side wall of the first mounting groove 14 is in close contact with the first support portion 22. The first support portion 22 is provided to support the expansion member 13, ensuring the stability and reliability of the assembly of the first bracket 21 and the expansion member 13 bracket, thereby ensuring that the first sealing member 31 can be firmly fixed between the expansion member 13 and the first bracket 21 during installation.

[0051] Therefore, the first support 22 provides good support for the heating tube 11 and the expansion member 13. The inclined extension of the first support 22 also facilitates the assembly between the expansion member 13 and the first bracket 21. It can play a certain limiting role in the first direction of the expansion member 13, ensuring the stable installation of the expansion member 13 and effectively enhancing the structural stability of the heating assembly 100.

[0052] According to some embodiments of this utility model, such as Figure 3 As shown, the first bracket 21 has a second support portion 23, which is located on the side of the first bracket 21 adjacent to the expansion member 13. The side wall of the first mounting groove 14 away from the heating tube 11 abuts against the second support portion 23.

[0053] The second support portion 23 extends radially away from the expansion member 13 along the first bracket 21. The second support portion 23 is adapted to abut against the side wall of the first mounting groove 14 away from the heating tube 11 in the first direction. That is, the side wall of the other side of the first mounting groove 14 is in close contact with the second support portion 23. The design of the second support portion 23 further enhances the support of the first bracket 21 for the expansion member 13 and ensures that the side wall of the first mounting groove 14 can be in close contact.

[0054] Therefore, the design of the first support part 22 and the second support part 23 can provide good support for the expansion member 13 and also ensure the correct installation position of the first seal 31, effectively enhancing the structural stability of the heating assembly 100.

[0055] According to some embodiments of this utility model, such as Figure 3 As shown, the plurality of seals include: a second seal 32, which is disposed between one end of the heating tube 11 adjacent to the expansion member 13 and the first bracket 21.

[0056] The second seal 32 is adapted to contact and abut against the outer peripheral surface of one end of the heating tube 11 adjacent to the expansion member 13 along the first direction, and the second seal 32 is adapted to contact and abut against the inner peripheral wall of the first bracket 21 adjacent to one end of the heating tube 11 along the first direction. The second seal 32 is disposed radially between the heating tube 11 and the first bracket 21. The second seal 32 is disposed on the side of the first seal 31 adjacent to the heating tube 11 along the first direction.

[0057] Therefore, the second seal 32 is located on the outer periphery of the heating tube 11. The position of the second seal 32 is far from the heating center and is less affected by high temperature. Moreover, this position is not located in front of the airflow channel, and only a very small amount of flue gas passes through the position of the second seal 32. The setting of the second seal 32 can ensure that the connection between the heating tube 11 and the first bracket 21 can maintain good sealing performance. The second seal 32 can prevent flue gas or condensate from seeping in from the gap between the heating tube 11 and the first bracket 21, further improving the overall sealing performance of the heating assembly 100.

[0058] According to some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, one end of the heating tube 11 is provided with a flange 12, which is folded from the inside to the outside toward the first bracket 21 along the radial direction of the heating tube 11; the first bracket 21 has a bent portion 24 formed at one end adjacent to the heating tube 11, which extends toward the heating tube 11, and the bent portion 24 and the flange 12 define a second mounting groove, and the second sealing member 32 is provided in the second mounting groove.

[0059] A flange 12 is provided at one end of the heating tube 11 adjacent to the expansion member 13 along the first direction. The flange 12 is formed by folding a portion of one end of the heating tube 11 radially outward toward the first bracket 21. A bent portion 24 is formed at one end of the first bracket 21 adjacent to the heating tube 11. The bent portion 24 extends radially toward the heating tube 11 from one end of the first bracket 21. There is a certain gap between the bent portion 24 and the flange 12, namely a second mounting groove, and the second sealing member 32 is adapted to be assembled in the second mounting groove. The flange 12 can restrict the upward movement of the second sealing member 32 in the first direction. The heating tube 11 is assembled from top to bottom along the first direction. The first bracket 21 cooperates with one end of the heating tube 11 through the bent portion 24 and the second sealing member 32. The bent portion 24 can restrict the downward movement of the second sealing member 32 in the first direction.

[0060] Therefore, the design of the flange 12 on the heating tube 11 increases the mechanical strength of the end of the heating tube 11 and provides a reference surface for installing the seal. The bent portion 24 is adapted to cooperate with the flange 12 on the heating tube 11, together defining the second mounting groove. The second mounting groove is used to install the second seal 32, ensuring that the second seal 32 can be tightly contacted and fixed between the heating tube 11 and the first bracket 21. By setting a flange 12 at one end of the heating tube 11 and setting a bent portion 24 on the first bracket 21 to form a second mounting groove for installing the second seal 32, the sealing performance of the heating assembly 100 can be further improved, while enhancing the structural strength of the heating assembly 100 and extending the service life of the heating assembly 100. The flue gas in the heating tube 11 moves from bottom to top along the first direction. The setting of the bent portion 24 allows the second seal 32 to avoid direct impact from the flue gas, reducing the probability of the second seal 32 being corroded by the condensate of the e-liquid and extending the service life of the second seal 32.

[0061] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the outer peripheral wall of the expansion member 13 is formed with a third mounting groove 15; the plurality of seals include: a third seal 33, which is disposed in the third mounting groove 15 and abuts against the third mounting groove 15 and the first bracket 21.

[0062] The third mounting groove 15 extends circumferentially along the expansion member 13. The third mounting groove 15 is formed by a portion of the outer peripheral wall of the expansion member 13 recessed radially toward the center of the expansion member 13. The third sealing member 33 is embedded in the third mounting groove 15 and makes tight contact with the inner wall of the third mounting groove 15 and the inner wall surface of the first bracket 21 adjacent to the expansion member 13. The third sealing member 33 is located on the side of the first sealing member 31 away from the heating tube 11 along the first direction.

[0063] Therefore, the third seal 33 further prevents flue gas or condensate from seeping into the heating assembly 100 through the gap between the expansion member 13 and the first bracket 21, ensuring smooth flue gas flow without leakage and further improving the sealing performance of the heating assembly 100. The third mounting groove 15 is suitable for accommodating the third seal 33, ensuring that the third seal 33 can be evenly distributed and tightly fitted between the expansion member 13 and the first bracket 21. The third mounting groove 15 also ensures the correct assembly and installation stability of the third seal 33, avoiding poor sealing caused by improper installation and improving the overall reliability of the heating assembly 100.

[0064] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the third seal 33 includes a first sub-seal 34, which is disposed in the third mounting groove 15 on the side adjacent to the heating tube 11, and is located between the third mounting groove 15 and the first bracket 21.

[0065] The first sub-seal 34 is located at one end of the third seal 33 adjacent to the heating tube 11 along the first direction. The first sub-seal 34 is directly impacted by the flue gas. The lower end of the third mounting groove 15 is used to fix the position of the first sub-seal 34, prevent the first sub-seal 34 from shifting, and also block most of the flue gas.

[0066] Therefore, the setting of the first sub-seal 34 can further enhance the sealing performance between the expansion member 13 and the first bracket 21. The first sub-seal 34 works together with the first seal 31 and the second seal 32. The first sub-seal 34 and the first seal 31 are located at different positions along the first direction of the heating assembly 100. Different sealing positions are affected by high-temperature flue gas impact and corrosion to different degrees. Different sealing structures 30 are adopted, which reduces the cost of the heating assembly 100 and improves the sealing effect.

[0067] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the third seal 33 further includes a second sub-seal 35, one end of which is disposed in the third mounting groove 15, and the other end of which extends along the axial direction of the heating tube 11 toward the end face of the expansion member 13 away from the heating tube 11.

[0068] A portion of the second sub-seal 35 is located at the end of the third seal 33 away from the heating tube 11 along the first direction. The other end of the second sub-seal 35 extends to the end of the expansion member 13 away from the heating tube 11, and at least a portion of the second sub-seal 35 is located outside the gap defined by the expansion member 13 and the first bracket 21. The other end of the second sub-seal 35 extends radially away from the expansion member 13, and the other end of the second sub-seal 35 is located at the opening sealing the gap between the expansion member 13 and the first bracket 21.

[0069] Therefore, the second sub-seal 35 can achieve secondary sealing based on the first sub-seal 34, and the second sub-seal 35 is used to prevent the intrusion of e-liquid from the outside of the heating assembly 100. Long-term use of the atomizing device will leave a small amount of e-liquid condensate on the top. The second sub-seal 35 can prevent the e-liquid condensate from intruding into the interior of the heating assembly 100 through the gap between the expansion member 13 and the first bracket 21, protecting the internal structure of the heating assembly 100 from corrosion and improving the reliability and safety of the heating assembly 100.

[0070] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the second sub-seal 35 includes: a first sealing section 351, a second sealing section 352, and a third sealing section 353. The first sealing section 351 is disposed in the third mounting groove 15. The second sealing section 352 contacts the expansion member 13 at the end face away from the heating tube 11. The third sealing section 353 is disposed between the first sealing section 351 and the second sealing section 352. The third sealing section 353, the first sealing section 351, and the second sealing section 352 define a fourth mounting groove. The end of the expansion member 13 away from the heating tube 11 mates with the fourth mounting groove.

[0071] The first sealing section 351 is installed in the third mounting groove 15, abutting against the third mounting groove 15 and the first bracket 21, ensuring that the second sub-seal 35 can form a seal at the end of the gap between the expansion member 13 and the first bracket 21 away from the air passage. The second sealing section 352 is installed on the end face of the expansion member 13 away from the heating tube 11 and contacts the expansion member 13. The fourth mounting groove defined by the third sealing section 353, the first sealing section 351, and the second sealing section 352 allows the end of the expansion member 13 away from the heating tube 11 to cooperate with the fourth mounting groove, effectively improving the assembly stability between the second sub-seal 35 and the expansion member 13.

[0072] Thus, the second sub-seal 35 and the first seal 31 achieve multiple seals in the gap between the expansion member 13 and the first bracket 21, effectively preventing flue gas or condensate from entering the heating assembly 100 or the atomizing device, thereby improving the overall sealing performance. The arrangement of the first sealing section 351, the second sealing section 352, and the third sealing section 353 effectively enhances the assembly stability between the second sub-seal 35 and the expansion member 13, thereby improving the overall structural strength of the heating assembly 100.

[0073] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, one of the contact surfaces of the fourth mounting groove and the expansion member 13 is provided with a mating protrusion 36, and the other of the contact surfaces of the fourth mounting groove and the expansion member 13 is provided with a mating groove 37. The mating protrusion 36 and the mating groove 37 are mated.

[0074] Taking the expansion member 13 having a mating protrusion 36 and the fourth mounting groove having a mating groove 37 as an example, the mating protrusion 36 is formed by the outer peripheral surface of the end of the expansion member 13 away from the heating tube 11 protruding radially in a direction away from the center of the expansion member 13, and the mating groove 37 is formed by the second sealing section 352 of the second sub-seal member 35 being recessed into a portion of the inner surface of the expansion member 13 in a direction away from the expansion member 13, and the mating protrusion 36 is embedded in the mating groove 37.

[0075] Therefore, the combination of the protrusion 36 and the groove 37 improves the assembly stability and reliability between the second sub-seal 35 and the expansion member 13, effectively enhancing the structural strength of the heating assembly 100.

[0076] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the third sealing section 353 has a protrusion on the side away from the expansion member 13, and the protrusion protrudes from the surface of the first bracket 21 on the side away from the expansion member 13.

[0077] The protrusion is designed to prevent contact and abutment between the heating component 100 and other structures when the heating component 100 is assembled in the atomizing device. The protrusion is also designed to prevent external e-liquid from entering. Long-term use of the atomizing device will leave a small amount of condensed vapor on the top. The protrusion can prevent the condensed vapor from entering the interior of the heating component 100, protect the internal structure of the heating component 100 from corrosion, and improve the reliability and safety of the heating component 100.

[0078] According to some embodiments of this utility model, such as Figure 3 As shown, the plurality of seals include: a fourth seal 38, which is located between the end of the heating tube 11 away from the expansion member 13 and the second bracket 25.

[0079] The fourth seal 38 is disposed on the outer peripheral surface of the heating tube 11 at the other end away from the expansion member 13 along the first direction. The fourth seal 38 is disposed between the outer peripheral surface of the heating tube 11 and the inner wall surface of the second bracket 25 adjacent to the heating tube 11. The fourth seal 38 is used to ensure the sealing performance between the heating tube 11 and the second bracket 25.

[0080] Therefore, the fourth seal 38 is located on the outer periphery of the heating tube 11. This position is far from the heating center and is less affected by high temperature. At the same time, this position is not in front of the airflow channel, and only a very small amount of flue gas will pass through the gap between the second bracket 25 and the heating tube 11, thus reducing the impact of flue gas corrosion. The setting of the fourth seal 38 can effectively improve the sealing performance between the heating tube 11 and the second bracket 25, while reducing production costs.

[0081] According to some embodiments of this utility model, such as Figure 3 As shown, the second bracket 25 has a mounting cavity 26, and the end of the heating tube 11 away from the expansion member 13 is engaged with the mounting cavity 26; the mounting cavity 26 includes a bottom surface and a side surface, and the fourth sealing member 38 is disposed between the side surface and the heating tube 11, and the connection between the bottom surface and the side surface is formed as an arc surface.

[0082] The second bracket 25 has a mounting cavity 26 for accommodating the end of the heating tube 11 away from the expansion member 13. A through hole is formed at the bottom of the mounting cavity 26, which is adapted to communicate with the air passage of the heating tube 11. The connection between the bottom and side surfaces of the mounting cavity 26 is formed into an arc surface to guide the flue gas towards the other end of the heating tube 11 along the first direction, towards the end of the heating tube 11 that mates with the expansion member 13 along the first direction. A groove 27 is formed on the side surface of the mounting cavity 26, which is the radial inner wall surface of the second bracket 25. The groove 27 is formed by a portion of the inner wall surface of the second bracket 25 recessed radially away from the center of the second bracket 25. The radial inner wall surface of the groove 27 is opposite to the radial outer surface of the heating tube 11, and one side surface of the groove 27 along the first direction abuts against the end face of the heating tube 11 along the first direction. The side surface of the mounting cavity 26 is flush with the radial inner wall surface of the heating tube 11.

[0083] Therefore, the mounting cavity 26 facilitates the cooperation between the second bracket 25 and the heating tube 11, allowing the heating tube 11 to be more securely mounted on the second bracket 25. The connection between the bottom and side surfaces of the mounting cavity 26 is formed into an arc surface, which is suitable for guiding the flue gas to flow from the other end of the heating tube 11 along the first direction to the end of the heating tube 11 that cooperates with the expansion member 13 along the first direction.

[0084] According to some embodiments of this utility model, such as Figure 3 As shown, at least one of the multiple seals that abuts against the expansion member 13 is a two-color injection molded part.

[0085] Two-color injection molding is a technique that involves simultaneously or sequentially injection molding two different colors or materials of plastic into the same mold. At least one of the multiple seals and the expansion component 13 are manufactured using two-color injection molding, so that the seal and the expansion component 13 are tightly bonded together, that is, the seal is tightly bonded to the expansion component 13 during the manufacturing process, forming a single integral component.

[0086] This results in a tighter fit between the seal and the expansion element 13, reducing the risk of poor sealing due to improper installation or wear during use, thereby improving sealing performance. The two-color injection molding design integrates the seal and expansion element 13 into a single unit, enhancing structural stability and reducing the risk of displacement due to thermal expansion or vibration. Integrating the seal and expansion element 13 into a single component simplifies the assembly process of the heating assembly 100, reducing the need for separate seal installation and improving production efficiency. The use of the two-color injection molding component enhances the overall reliability of the heating assembly 100, reduces malfunctions caused by poor sealing, and extends the service life of the atomizing device.

[0087] The atomizing device according to a second aspect of the present invention includes a heating component 100 according to the first aspect of the present invention described above.

[0088] The atomizing device according to the embodiments of the present invention, by applying the heating component 100 described in the above embodiments, effectively improves the overall sealing and structural reliability of the atomizing device, which is beneficial to extending the service life of the atomizing device.
