Description

Technical Field

[0001] The present application relates to the technical field of atomization, and particularly to an aerosol generating device and an aerosol generating system. Background Art

[0002] A heat not burning (HNB) aerosol generating system is a combined device of an aerosol generating device and an aerosol generating article. The aerosol generating device includes a receiving tube and a heating assembly. The heating assembly heats the aerosol generating article to form an aerosol in the receiving tube. The airway holes of the receiving tube communicate with the intake path. External gas enters the receiving tube through the intake path and the airway holes to extract the aerosol generated by heating the aerosol generating article.

[0003] However, part of the aerosol in the receiving tube will flow into the intake path through the airway holes of the receiving tube to form condensate, resulting in an increase in the condensate in the intake path and possible blockage of the intake path. Summary of the Utility Model

[0004] The main technical problem to be solved by the present application is to provide an aerosol generating device and an aerosol generating system to solve the problem of excessive condensate in the intake path.

[0005] To solve the above technical problem, the first technical solution adopted by the present application is: to provide an aerosol generating device. The aerosol generating device includes a receiving assembly and a heating assembly; the receiving assembly includes a bracket, a receiving tube and a heat conducting structure; the bracket has a mounting groove; at least part of the receiving tube is located in the mounting groove; the receiving tube is used to accommodate an aerosol generating matrix; the heating assembly includes a heating part and a mounting part; the heating part passes through the bottom wall of the receiving tube and extends into the aerosol generating matrix; wherein, the heating part includes a connected first sub-part and a second sub-part, the mounting part is connected to the second sub-part; the first sub-part is located in the receiving tube; at least part of the second sub-part is located outside the receiving tube; the second sub-part is correspondingly arranged with the heat conducting structure, and the heat conducting structure is at least used to absorb part of the heat of the second sub-part.

[0006] Since the heat-conducting structure is arranged corresponding to the second sub-section, the heat-conducting structure mainly absorbs the heat of the second sub-section, and of course, it can also absorb or not absorb part of the heat of the first sub-section. The second sub-section of the heating section consumes more heat, while the heat of the first sub-section remains basically unchanged or slightly decreases, so that the temperature of the first sub-section of the heating section is greater than the temperature of the second sub-section of the heating section. Since the second sub-section is close to the bottom wall of the containing tube, the first sub-section is far away from the bottom wall of the containing tube, and the temperature of the first sub-section is greater than the temperature of the second sub-section, the aerosol generating matrix is ​​divided into a first zone and a retention zone located between the first zone and the bottom wall of the containing tube. At least part of the second sub-section corresponds to the retention zone, so that the temperature of the retention zone is lower; the first zone corresponds to the first sub-section, so that the temperature of the first zone is greater than the temperature of the retention zone.

[0007] Since the temperature of the interception zone is lower than that of the first zone, the amount of aerosol-generating substrate atomized in the interception zone will also be correspondingly smaller than the amount of aerosol-generating substrate atomized in the first zone, making the interception zone denser and having smaller pores than the first zone, thereby making it difficult for the aerosol atomized in the first zone to flow back through the airway holes in the interception zone and enter the first air inlet path, so that the interception zone plays a role in hindering the backflow of aerosol; thereby reducing the condensate in the first air inlet path.

[0008] In addition, since the temperature of the interception zone is relatively low, the aerosol generated in the interception zone is also relatively small, and the aerosol generated in the interception zone and entering the first air intake path through the airway hole is also relatively small, so that the condensate generated by the aerosol in the first air intake path is relatively small, thereby reducing the condensate in the first air intake path. Since the condensate in the first air intake path is reduced, the possibility of blockage of the first air intake path is reduced.

[0042] References herein to "embodiments" mean that the particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0043] Embodiments of the present disclosure provide an aerosol generating system. The aerosol generating system can be used in different fields such as medical, beauty, and recreational inhalation. Refer to Figure 1 and Figure 2 , the aerosol generating system may include an aerosol generating device 3 and an aerosol generating article 1. In some examples, the aerosol generating system may further include a housing 2; the heating component 32 and the bracket 311 described below may be disposed within the housing 2. The housing 2 is a prior art and will not be elaborated. Of course, the aerosol generating system may further include components such as a power source, a circuit board, a seal, and a fixing member, which are prior art and will not be elaborated.

[0044] The aerosol generating article 1 includes a filter segment 11, a connection segment 12, and a matrix segment connected in sequence. The matrix segment includes an aerosol generating matrix 13. The aerosol generating device 3 is configured to heat the aerosol generating matrix 13 to form an aerosol when powered on. The filter segment 11 is configured to filter the aerosol. The connection segment 12 is configured to reduce the temperature of the aerosol formed by atomization and prevent scalding. The other specific structures and functions of the filter segment 11, the connection segment 12, and the matrix segment are the same as or similar to those of the prior aerosol generating article 1 and will not be elaborated herein.

[0045] Refer to Figure 2 and Figure 3 , the aerosol generating device 3 may include a receiving component 31 and a heating component 32.

[0046] The receiving component 31 has a first air intake path 34, and the first air intake path 34 communicates with the outside, and outside air can enter the first air intake path 34.

[0047] The receiving component 31 includes a receiving tube 312, a heat conducting structure 313, and a bracket 311. The bracket 311 has a mounting groove 3111. At least a part (such as a part, or all) of the receiving tube 312 is located within the mounting groove 3111.

[0048] Refer to Figure 4 and Figure 5, the receiving tube 312 includes a connected bottom wall and side wall, and the receiving tube 312 has a receiving opening 3125 opposite to the bottom wall. The receiving tube 312 is connected to the bracket 311. In some examples, the aerosol generating device 3 further includes a cover plate 35. The cover plate 35 is detachably connected to the bracket 311. The rib 3121 of the receiving tube 312 is clamped between the cover plate 35 and the bracket 311. In this way, after removing the cover plate 35, the receiving tube 312 can be taken out from the installation groove 3111; after installing the cover plate 35, the receiving tube 312 can be fixed in the installation groove 3111. Thus, by using the clamping cooperation of the cover plate 35 and the bracket 311, the receiving tube 312 can be quickly disassembled and assembled. The number of ribs 3121 can be one or multiple; for example, the number of ribs 3121 is two, and the two ribs 3121 are arranged oppositely. The rib 3121 is arranged on the side wall of the receiving tube 312; for example, the rib 3121 is arranged on the side wall of the receiving tube 312 and is flush with the top surface of the side wall. In some other examples, the receiving tube 312 can be directly fixedly installed in the installation groove 3111 without the aid of the cover plate 35.

[0049] Continue to refer to Figure 4 and Figure 5 , the receiving tube 312 has airway holes 3122, and the first intake path 34 communicates with the airway holes 3122; thus, external gas enters the receiving tube 312 through the first intake path 34 and the airway holes 3122. The number of airway holes 3122 can be multiple, for example, multiple airway holes 3122 are circularly arrayed. The shape of the airway holes 3122 can be circular, and of course, it can also be other shapes such as rectangular or elliptical. The airway holes 3122 can be opened on the bottom wall of the receiving tube 312; or for another example, the airway holes 3122 can be opened on the side wall of the receiving tube 312 but close to the bottom wall of the receiving tube 312. In this article, the example where the airway holes 3122 can be opened on the bottom wall of the receiving tube 312 is used for illustration.

[0050] At least a part (such as part, or for another example, all) of the aerosol generating article 1 is inserted into the receiving tube 312, for example, the matrix section of the aerosol generating article 1 is inserted into the receiving tube 312, or for another example, both the matrix section and the connection section 12 of the aerosol generating article 1 are inserted into the receiving tube 312. The aerosol generating article 1 abuts against the bottom wall of the receiving tube 312, for example, the matrix section of the aerosol generating article 1 abuts against the bottom wall of the receiving tube 312.

[0051] External gas enters the matrix section of the aerosol generating article 1 through the airway holes 3122, carries the aerosol generated by the matrix section, and flows out from the filter section 11 for the user to inhale.

[0052] Continue to refer to Figure 2 and Figure 3, the heating component 32 can be a structure capable of providing heat. The heating component 32 can include a heating part 321 and a mounting part 322; the mounting part 322 is located outside the receiving tube 312, and the heating part 321 extends through the bottom wall of the receiving tube 312 into the receiving tube 312 to heat the aerosol production matrix. The heating part 321 can be a heating needle.

[0053] The mounting part 322 can be located outside the bracket 311. In this case, the heating part 321 of the heating component 32 needs to pass through the bottom wall of the bracket 311 and the bottom wall of the receiving tube 312 to be located inside the receiving tube 312. Of course, the mounting part 322 can also be located between the bracket 311 and the receiving tube 312. In this case, the heating part 321 of the heating component 32 only needs to pass through the bottom wall of the receiving tube 312, but does not need to pass through the bottom wall of the bracket 311, and the heating part 321 can be located inside the receiving tube 312. In this article, the case where the mounting part 322 can be located outside the bracket 311 is taken as an example for illustration. The heating part 321 located inside the receiving tube 312 is used to extend into the aerosol generating article 1, and at least part of the heating part 321 (for example, the heating part 321 located inside the receiving tube 312) heats the aerosol generating article 1.

[0054] The heating part 321 includes a connected first sub-part 3211 and a second sub-part 3212, and the mounting part 322 is connected to the second sub-part 3212; the first sub-part 3211 is located inside the receiving tube 312; at least part of the second sub-part 3212 is located outside the receiving tube 312; the heat conducting structure 313 is correspondingly arranged with the second sub-part 3212, and the heat conducting structure 313 is at least used to absorb part of the heat of the second sub-part 3212.

[0055] The first sub-part 3211 is directly connected to the second sub-part 3212 in direct contact, and the second sub-part 3212 is directly connected to the mounting part 322 in direct contact. Of course, the second sub-part 3212 and the mounting part 322 can be indirectly connected. For example, the second sub-part 3212 is in contact connection with the mounting part 322 through a third sub-part of the heating part.

[0056] Since the first sub-part 3211 is located inside the receiving tube 312, the first sub-part 3211 directly heats the aerosol production matrix 13.

[0057] At least part of the second sub-part 3212 is located outside the receiving tube 312. For example, all of the second sub-part 3212 is located outside the receiving tube 312. Another example is that a part of the second sub-part 3212 is located outside the receiving tube 312 and another part is located inside the receiving tube 312. In some examples, the second sub-part 3212 located outside the receiving tube 312 can pass through the bottom wall of the bracket 311 and be located outside the bracket 311; at this time, the mounting part 322 can only be located outside the bracket 311. Of course, the second sub-part 3212 located outside the receiving tube 312 can only be located between the receiving tube 312 and the bracket 311.

[0058] The second sub - part 3212 is correspondingly arranged with the heat - conducting structure 313, that is, along the radial direction of the receiving tube 312, the heat - conducting structure 313 is oppositely arranged with respect to the second sub - part 3212 and is close to the second sub - part 3212. For example, the heat - conducting structure 313 is arranged to surround the second sub - part 3212. Another example is that the second sub - part 3212 passes through the heat - conducting structure 313.

[0059] Since the heat - conducting structure 313 is correspondingly arranged with the second sub - part 3212, the heat - conducting structure 313 mainly absorbs the heat of the second sub - part 3212. Of course, it can also absorb part of the heat of the first sub - part 3211 close to the second sub - part 3212. As a result, more heat of the second sub - part 3212 and the part of the first sub - part 3211 close to the second sub - part 3212 is consumed, while the heat of the part of the first sub - part 3211 far from the second sub - part 3212 remains basically unchanged or slightly decreases, making the temperature of the part of the first sub - part 3211 far from the second sub - part 3212 higher than the temperature of the second sub - part 3212 and the part of the first sub - part 3211 close to the second sub - part 3212.

[0060] Since the first sub - part 3211 is located inside the receiving tube and is inserted into the aerosol - generating substrate 13 to heat it, the temperature of the aerosol - generating substrate 13 corresponding to the first sub - part 3211 is roughly divided into two temperature zones, that is, the first zone 131 far from the second sub - part 3212 and the intercepted zone 132 close to the second sub - part 3212. The temperature of the first zone 131 is higher than that of the intercepted zone 132. Among them, both the first zone 131 and the intercepted zone 132 can generate aerosol.

[0061] Since the temperature of the intercepted zone 132 is lower than that of the first zone 131, the amount of the aerosol - generating substrate atomized in the intercepted zone 132 will correspondingly be less than the amount of the aerosol - generating substrate atomized in the first zone 131, making the intercepted zone 132 denser and having smaller pores relative to the first zone 131. As a result, the aerosol atomized in the first zone 131 is not easily reversed through the intercepted zone 132 back into the airway hole 3122 and into the first intake path 34, so that the intercepted zone 132 plays a role in hindering the reverse flow of aerosol; thereby reducing the condensate in the first intake path 34.

[0062] In addition, since the temperature of the intercepted zone 132 is relatively low, the amount of aerosol generated in the intercepted zone 132 is also small, and the amount of aerosol generated in the intercepted zone 132 entering the first intake path 34 through the airway hole 3122 is also small, making the amount of condensate generated by the aerosol in the first intake path 34 small, thereby reducing the condensate in the first intake path 34.

[0063] The heat-conducting structure 313 can be a type of heat-conducting material with a relatively high heat conductivity. In some examples, the heat conductivity of the heat-conducting structure 313 is greater than or equal to 5 W / (m·K). For example, the heat conductivity of the heat-conducting structure 313 is greater than or equal to 6 W / (m·K), 7 W / (m·K), 8 W / (m·K), 9 W / (m·K), 10 W / (m·K), 11 W / (m·K), 12 W / (m·K), 13 W / (m·K), 15 W / (m·K), etc. In some examples, the heat-conducting material can be metal, heat-conducting ceramic, or heat-conducting plastic. For example, the metal can be aluminum alloy, stainless steel, etc.

[0064] The shape of the heat-conducting structure 313 can be sheet-shaped, block-shaped, or other shapes; in different embodiments, the shape of the heat-conducting structure 313 can be designed according to different situations.

[0065] In some embodiments, continue to refer to Figure 2 and Figure 3 , the heat-conducting structure 313 is located between the bottom wall of the receiving tube 312 and the bottom wall of the bracket 311 and is connected to the bracket 311. The heat-conducting structure 313 is correspondingly arranged with a part of the second sub-part 3212 located outside the receiving tube 312.

[0066] One surface of the heat-conducting structure 313 away from the bottom wall of the bracket 311 and the outer bottom wall of the receiving tube 312 enclose a first air intake path 34. An air passage hole 3122 is formed on the bottom wall of the receiving tube 312.

[0067] The heat-conducting structure 313 absorbs the heat of the second sub-part 3212 of the heating part 321, causing the temperature of the heat-conducting structure 313 to rise; since the heat-conducting structure 313 is part of the first air intake path 34, the relatively high-temperature heat-conducting structure 313 can directly heat the aerosol in the first air intake path 34, enabling the aerosol in the first air intake path 34 to re-enter the receiving tube 312 through the air passage hole 3122, thereby reducing the condensate in the first air intake path 34.

[0068] One surface of the heat-conducting structure 313 away from the bottom wall of the bracket 311 and the outer bottom wall of the receiving tube 312 are both flat. In this way, the first air intake path 34 is a straight channel. Of course, at least one of one surface of the heat-conducting structure 313 away from the bottom wall of the bracket 311 and the outer bottom wall of the receiving tube 312 can also be a curved surface.

[0069] The heat-conducting structure 313 has a first mounting hole 3131; the heating part 321 sequentially passes through the bottom wall of the bracket 311, the first mounting hole 3131 and the bottom wall of the receiving tube 312, and extends into the receiving tube 312. Wherein, the bottom wall of the bracket 311 has a second mounting hole, and the bottom wall of the receiving tube 312 has a third mounting hole 3123; the axes of the first mounting hole 3131, the second mounting hole and the third mounting hole 3123 are coaxially arranged; the heating part 321 sequentially passes through the second mounting hole, the first mounting hole 3131 and the third mounting hole 3123 and extends into the receiving tube 312.

[0070] The second sub-part 3212 is arranged in the first mounting hole 3131, and the distance between the second sub-part 3212 and the first mounting hole 3131 is 0.15 mm to 0.30 mm. For example, the distance between the second sub-part 3212 and the first mounting hole 3131 can be 0.15 mm, 0.18 mm, 0.20 mm, 0.22 mm, 0.25 mm, 0.27 mm, 0.30 mm, etc. If the distance between the second sub-part 3212 and the first mounting hole 3131 is less than 0.15 mm, the heating part 321 cannot pass through the heat-conducting structure 313 smoothly, and the heat-conducting structure 313 may be damaged due to contact during the heating process; if the distance between the second sub-part 3212 and the first mounting hole 3131 is greater than 0.3 mm, the heat-conducting effect of the heat-conducting structure 313 becomes poor, and at the same time, the condensate is likely to flow into the heating assembly 32 through the first mounting hole 3131.

[0071] Wherein, both the first sub-part 3211 and the second sub-part 3212 are cylindrical, have the same diameter and are coaxially arranged; one end of the first sub-part 3211 away from the second sub-part 3212 can be provided with a tip for facilitating the extension into the aerosol generating substrate 13.

[0072] The heat-conducting structure 313 is connected to the bottom wall of the bracket 311 and is not connected to the side wall of the bracket 311; for example, the heat-conducting structure 313 is connected to the bottom wall of the bracket 311 through an adhesive. Of course, the heat-conducting structure 313 can also be connected to the bottom wall of the bracket 311 and connected to the side wall of the bracket 311. The material of the receiving tube 312 can be a non-heat-conducting material such as plastic, and of course, it can also be a metal material.

[0073] In some examples, see Figure 6, the heat conduction structure 313 is a heat conduction plate 3132. The heat conduction plate 3132 has opposite first and second plate surfaces; the second plate surface of the heat conduction plate 3132 is in contact connection with the bottom wall of the bracket 311, and the first plate surface of the heat conduction plate 3132 and the outer bottom wall of the receiving tube 312 enclose a first air intake path 34. The heat conduction plate 3132 has a first mounting hole 3131. The thickness of the heat conduction plate 3132 is 0.5 mm to 1.0 mm. For example, the thickness of the heat conduction plate 3132 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc. If the thickness of the heat conduction plate 3132 is less than 0.5 mm, the heat absorption of the heat conduction structure 313 from the heat generating part is insufficient to achieve the effect of improving the condensate; if the thickness of the heat conduction plate 3132 is greater than 1.0 mm, the heat absorption of the heat conduction structure 313 from the heat generating part is relatively large, increasing the energy consumption of the heat generating component.

[0074] In some other examples, refer to Figure 7 and Figure 8 , the heat conduction structure 313 includes a heat conduction plate 3132 and a heat conduction part 3133. The heat conduction plate 3132 has opposite first and second plate surfaces; the heat conduction part 3133 is arranged on the second plate surface and is in contact connection with the bottom wall of the bracket 311; the first plate surface of the heat conduction plate 3132 and the outer bottom wall of the receiving tube 312 enclose a first air intake path 34. The heat conduction plate 3132 has a first mounting hole 3131, and the heat conduction part 3133 is arranged at an interval from the first mounting hole 3131. Refer to Figure 7 , for example, the outer side wall of the heat conduction plate 3132 is flush with the outer side wall of the heat conduction part 3133. Refer to Figure 8 , or for another example, the outer side wall of the heat conduction plate 3132 is not flush with the outer side wall of the heat conduction part 3133, that is, there is a distance between the two. The heat conduction part 3133 can be an annular plate, with one end arranged on the second plate surface and the other end being an opening. Of course, the heat conduction part 3133 can also be in the structure of a column, a block, etc. The thickness of the heat conduction plate 3132 is 0.5 mm to 1.0 mm. For example, the thickness of the heat conduction plate 3132 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0075] In some embodiments, refer to Figure 9 , a part of the second sub - part 3212 is located inside the receiving tube 312, and the other part is located outside the receiving tube 312. The heat conduction structure 313 is located inside the receiving tube 312 and is in contact connection with the bottom wall of the receiving tube 312; the heat conduction structure 313 is correspondingly arranged with the part of the second sub - part 3212 located inside the receiving tube 312. Among them, the second sub - part 3212 also penetrates through the bottom wall of the receiving tube 312.

[0076] The heat-conducting structure 313 exposes the air passage hole 3122; the bottom wall of the bracket 311 and the bottom wall of the receiving tube 312 enclose a first air intake path 34. The heating part passes through the heat-conducting structure 313. In this way, the heat-conducting structure 313 in the receiving tube 312 can absorb the heat of the second sub-part 3212 of the heating part 321, so that the aerosol-forming substrate 13 is roughly divided into a first area 131 and a retention area 132. The material of the receiving tube 312 can be a non-heat-conducting material such as plastic, or it can also be a metal material.

[0077] In this embodiment, for the description of the shape and structure of the heat-conducting structure 313, and the distance between the second sub-part 3212 and the first mounting hole, reference can be made to the relevant description of the embodiment where the heat-conducting structure 313 is located between the receiving tube 312 and the bracket 311 above.

[0078] In some embodiments, a part of the second sub-part 3212 is located inside the receiving tube 312, and the other part is located outside the receiving tube 312. The heat-conducting structure 313 at least includes the bottom wall of the receiving tube 312; the bottom wall of the receiving tube 312 is correspondingly arranged with the part of the second sub-part 3212 located inside the receiving tube 312.

[0079] The bottom wall of the bracket 311 and the bottom wall of the receiving tube 312 enclose a first air intake path 34. In this way, the bottom wall of the receiving tube 312 can absorb the heat of the second sub-part 3212 of the heating part 321, so that the aerosol-forming substrate 13 is divided into a first area 131 and a retention area 132. In addition, the bottom wall of the receiving tube 312 is a part of the structure constituting the first air intake path 34, so the bottom wall of the receiving tube 312 can directly heat the aerosol in the first air intake path 34.

[0080] In this embodiment, for example, the heat-conducting structure 313 is the bottom wall of the receiving tube 312. At this time, the side wall of the receiving tube 312 and the materials of other structures can be non-heat-conducting materials such as plastic. Another example is that the heat-conducting structure 313 includes the bottom wall of the receiving tube 312 and a part of the side wall close to the bottom wall of the receiving tube 312. At this time, the part of the side wall of the receiving tube 312 far from the bottom and the materials of other structures can be non-heat-conducting materials such as plastic. Of course, the entire receiving tube 312 can also be the heat-conducting structure 313. At this time, as long as the heat of the second sub-part 3212 of the heating part 321 is less than the heat of the first sub-part 3211 of the heating part 321, so that the aerosol-forming substrate 13 is divided into a first area 131 and a retention area 132.

[0081] In this embodiment, the second sub - part 3212 is disposed in the third mounting hole 3123, and the bottom wall of the receiving tube 312 is at least part of the heat - conducting structure 313; the distance between the second sub - part 3212 and the third mounting hole 3123 is 0.15 mm to 0.30 mm. Among them, for the description of the shape and structure of the heat - conducting structure 313, reference can be made to the relevant description of the embodiment where the heat - conducting structure 313 is located between the receiving tube 312 and the bracket 311. For the description of the distance between the second sub - part 3212 and the third mounting hole 3123 being 0.15 mm to 0.30 mm, reference can be made to the relevant description of the distance between the second sub - part 3212 and the first mounting hole being 0.15 mm to 0.30 mm.

[0082] Continuing to refer to Figure 2 and Figure 3 , the first intake path 34 can be only the horizontal intake path as shown in the figure. Of course, the first intake path 34 can also be the horizontal intake path and the vertical intake path as shown in the figure. Here, taking the example that the first intake path 34 can be only the horizontal intake path as shown in the figure, for example, an intake hole communicating with the first intake path 34 is provided on the side wall of the receiving tube 312, and external gas enters the first intake path 34 from the intake hole. Another example is that the first intake path 34 communicates with the second intake path 33 described below.

[0083] The bottom wall of the receiving tube 312 is part of the first intake path 34 surrounded, that is, the first intake path 34 can be the horizontal intake path as shown in the figure. That is to say, the first intake path 34 is surrounded by the bottom wall of the receiving tube 312 and the bottom wall of the heating structure or the mounting groove 3111. The distance of the first intake path 34 along the extension direction of the heating part 321 is 0.3 mm to 0.8 mm; for example, the distance of the first intake path 34 along the extension direction of the heating part 321 is 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, etc. If the distance of the first intake path 34 along the extension direction of the heating part 321 is less than 0.3 mm, the suction resistance is too large; if the distance of the first intake path 34 along the extension direction of the heating part 321 is greater than 0.8 mm, the flow rate of the external gas is too small and the condensate increases.

[0084] In addition, since the heating part 321 passes through the first intake path 34, and the distance of the first intake path 34 along the extension direction of the heating part 321 is 0.3 mm to 0.8 mm; during the suction process, the condensate in the first intake path 34 is driven by the suction air flow to move towards the heating part 321, and the high temperature on the surface of the heating part 321 is used to evaporate the condensate that touches the heating part 321, thereby reducing the condensate in the first intake path 34.

[0085] In some examples, a second intake path 33 is formed between the side wall of the bracket 311 and the side wall of the receiving pipe 312, and the second intake path 33 communicates with the first intake path 34; a plurality of bumps are provided at intervals on the side wall of the receiving pipe 312; one end of the second intake path 33 away from the first intake path 34 has a plurality of air inlets, and at least two adjacent bumps enclose an air inlet. For example, two adjacent bumps enclose an air inlet. Another example is that two adjacent bumps, a part of the cover plate 35 and a part of the bracket 311 jointly enclose an air inlet. External gas enters the second intake path 33 from the air inlet, and the external gas in the second intake path 33 enters the first intake path 34.

[0086] The above are only the embodiments of the present application, and do not limit the patent protection scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
