- a

FIG. 3 toFIG. 5 , the rigidupper holder 40 and the flexiblelower holder 50 are assembled in themain housing 10 to fix thevaporization assembly 30. Specifically referring toFIG. 3 andFIG. 4 , a clampingarm 44 extending out is arranged on theupper holder 40, and thevaporization assembly 30 abuts against or is clamped on thelower holder 50 by the clampingarm 44. Moreover, a firstconcave cavity 43 facing thelower holder 50 is provided in theupper holder 40, and a secondconcave cavity 52 facing theupper holder 40 is provided in thelower holder 50, such that, after assembly, the firstconcave cavity 43 and the secondconcave cavity 52 together form a vaporization cavity, which encircles or surrounds thevaporization assembly 30 and accommodates an aerosol that is released and generated. - In a preferred implementation shown in
FIG. 4 , a carryinggroove 51 that is opposite an end part of theliquid guide element 31 is further provided in thelower holder 50, and is configured to carry a liquid substrate that seeps from the end part of theliquid guide element 31. - To facilitate the sealing of a gap between the
upper holder 40 and theliquid storage cavity 12, thevaporizer 100 further includes a sealingelement 60, which is at least partially located between theupper holder 40 and theliquid storage cavity 12, so as to seal theliquid storage cavity 12. Theliquid guide element 31 and theheating element 32, after being mounted, are both mainly accommodated within the vaporization cavity to release a generated aerosol to the vaporization cavity, and the aerosol is outputted to thevapor output pipe 11 through afirst insertion hole 61 in the sealingelement 60. - Furthermore, a bottom wall of the second
concave cavity 52 of thelower holder 50 is further provided with ahole 53, which is opposite theair inlet 22 in theend cover 20, and external air entering from theair inlet hole 22 enters the vaporization cavity through thehole 53. - With regard to a design of an outputted airflow of an aerosol, the
upper holder 40 is provided with asecond insertion hole 41. The end part of thevapor output pipe 11 penetrates thefirst insertion hole 61 in the sealingelement 60 and is then further inserted into thesecond insertion hole 41. Two sides of theupper holder 40 in the thickness direction are provided withoutput channels 45, such that the aerosol within the vaporization cavity is outputted to thevapor output pipe 11 along an arrow R2 shown inFIG. 3 andFIG. 6 . - To cooperate with the
vaporization assembly 30 for liquid guide, the sealingelement 60 is provided with a firstliquid guide hole 62 for the liquid substrate to flow toward theupper holder 40. Theupper holder 40 is further provided with a secondliquid guide hole 42. When in use, the liquid substrate in theliquid storage cavity 12 sequentially passes through the firstliquid guide hole 62 and the secondliquid guide hole 42, and is transferred to thevaporization assembly 30 and is absorbed and vaporized. - Furthermore, in a preferred implementation shown in
FIG. 8 andFIG. 9 , a transversely extending blockingportion 46 is arranged in theupper holder 40, and the blocking portion delimits the firstconcave cavity 43. A projection of the blockingportion 46 in the longitudinal direction of thevaporizer 100 covers theheating element 32, such that, when in use, the blocking portion can block large droplets formed by an e-liquid blast during a heating process of theheating element 32; moreover, the blocking portion can also block a condensate and the like within the vaporization cavity, preventing same from directly flowing toward thevapor output pipe 11. - Further referring to the preferred embodiment shown in
FIG. 6 toFIG. 9 , a lower end part of thevapor output pipe 11 that is inserted into theupper holder 40 is provided with at least onenotch 111, and theupper holder 40 is provided with aridge 47, which fits thenotch 111. Specifically, inFIG. 8 , theridge 47 extends in the longitudinal direction of thevaporizer 100, and has two portions having different widths, i.e. afirst portion 471 that is close to thevapor output pipe 11, and asecond portion 472 that is relatively away from thevapor output pipe 11. Thefirst portion 471 has a smaller width than thesecond portion 472, and thefirst portion 471 is thinner than thesecond portion 472 in terms of form. In the implementation shown inFIG. 9 , thefirst portion 471 has a width of approximately 0.3 mm to 0.8 mm, and thesecond portion 472 has a width of approximately 0.8 mm to 1.5 mm. Thenotch 111 has a width of approximately 1.2 mm. - The form after assembly is as shown in
FIG. 9 . Thefirst portion 471 at least partially extends into thenotch 111 at the lower end of thevapor output pipe 11, and thesecond portion 472 is located outside thenotch 111. Moreover, after assembly, two side surfaces of thefirst portion 471 are not in contact with two side surfaces of thenotch 111, and according toFIG. 9 , there is spacing kept between the two side surfaces of thefirst portion 471 and the two side surfaces of thenotch 111. Furthermore, the spacing is controlled smaller than 2 mm, so as to form thecapillary channel 80 that longitudinally extends. Therefore, during use, when an aerosol condensate formed on an inner wall of thevapor output pipe 11 falls or flows downward to a lower end under gravity, the condensate at the lower end of thevapor output pipe 11 is guided downward into theholder 40 by a capillary adsorbing and guiding acting force of thecapillary channel 80, so as to avoid the condensate from accumulating at the inner wall or the lower end of thevapor output pipe 11, thereby alleviating or eliminating the problem of inhaling the condensate. - Further referring to the preferred implementation shown in
FIG. 8 , a lower end of theridge 47 is connected to the blockingportion 46, such that the condensate that is drawn and guided by thecapillary channel 80 drips onto the blockingportion 46. In the preferred implementation shown inFIG. 8 andFIG. 9 , the blockingportion 46 is arc-shaped, and thus the condensate that subsequently flows and falls onto the blockingportion 46 is guided downward from an upper surface of the arc, so as to flow and fall into the vaporization cavity, as indicated by an arrow R3 shown inFIG. 9 . - In the preferred implementation shown in
FIG. 8 , the extension length of thesecond portion 472 is greater than that of thefirst portion 471. In the implementation, the length of thesecond portion 472 is approximately 3 mm, and the length of thefirst portion 471 is approximately 2 mm. - Furthermore, in another optional implementation, the
ridge 47 further includes aflow guide groove 473, which is delimited by thesecond portion 472 and a wall of theupper holder 40. InFIG. 8 , there is theflow guide groove 473 at a portion where thesecond portion 472 is combined with theupper holder 40, and theflow guide groove 473 further facilitates quickly guiding the condensate, which is transferred by thecapillary channel 80, onto the blockingportion 46, avoiding the condensate from being adsorbed and held in thecapillary channel 80 between thefirst portion 471 and thevapor output pipe 11. - In another variant implementation, the
vaporization assembly 30 may also be a currently common vaporization assembly that is made of porous ceramics. The porous ceramics may be the porous ceramics body that has a transversely penetrating liquid channel as provided by the applicant in the patent No. 201920645593.5, or common cup-shaped ceramics that is provided with a groove in an upper surface thereof. When being assembled, the liquid substrate is also accommodated, held and transferred to the porous ceramics by theupper holder 50. - In another optional or variant implementation, the
ridge 47 may change into another shape or position. For example,FIG. 10 shows a schematic structural diagram of another upper holder 50 a that is provided with aridge 47 a. The size of theridge 47 a inFIG. 10 is larger than that of theridge 47 inFIG. 8 . In terms of shape, theridge 47 a is also provided with afirst portion 471 a and asecond portion 472 a, moreover, a longitudinally extendingflow guide groove 473 a is formed at a portion where thesecond portion 472 a is joined to awall 400 a of theupper holder 40 a, transferring the condensate downward more quickly. - The
first portion 471 a is closer to the center than thefirst portion 471, and is also not in contact with thewall 400 a of theupper holder 40 a, such that anaccommodating space 4711 a is formed between thefirst portion 471 a and the wall. After assembly, thenotch 111 at the lower end of thevapor output pipe 11 extends into theaccommodating space 4711 a, such that the space of thecapillary channel 80 between theridge 47 a and thevapor output pipe 11 can be further enlarged, which is conducive to the receiving and accommodating of more aerosol condensate. Similarly, after assembly, a part of thefirst portion 471 a still extends into thenotch 111 of thevapor output pipe 11, and certain spacing is kept, forming the capillary channel that adsorbs and transfers the condensate at the lower end of thevapor output pipe 11. -
FIG. 11 shows a schematic diagram of a vapor output pipe 11 a that is manufactured in amain housing 10 a in another embodiment. In the implementation shown inFIG. 11 , the cross-sectional shape of the vapor output pipe 11 a is a flat shape, and preferably an elliptical shape. Moreover, the elliptical shape takes the width direction of themain housing 10 a as a long axis B1 and the thickness direction of themain housing 10 a as a short axis B2, such that the condensate in the vapor output pipe 11 a tends more to accumulate at an end part of the long axis B1 that has a larger curvature. Therefore, the end part of the vapor output pipe 11 a is provided with asecond notch 112 a close to at least one side of themain housing 10 a in the width direction. By using thesecond notch 112 a, the end part of the long axis B1 that has the larger curvature forms a hollowed space, and thus the condensate is prevented from accumulating here and turns to more accumulate to a position close to thefirst notch 111 a, and is then guided into the vaporization cavity more easily under the cooperation of theridge 47. Certainly, to further fit the elliptical or flat vapor output pipe 11 a, thefirst insertion hole 61 and thesecond insertion hole 41 above are also of a flat or elliptical shape for fitting. Similarly, in conjunction with the above implementations, the position of theridge 47 needs to be adjusted to fit thefirst notch 111 a to form the capillary channel, so as to guide the aerosol condensate. - In a preferred implementation shown in
FIG. 11 , thefirst notch 111 a has a width greater than that of thesecond notch 112 a. In the implementation, the width of thefirst notch 111 a is approximately 2.4 mm, and the width of thesecond notch 112 a is approximately 1 mm. - To be sure, the description of the present application and the accompanying drawings thereof illustrate preferred embodiments of the present application, but are not limited to the embodiments described in this description; furthermore, a person of ordinary skill in the art may make improvements or modifications according to the foregoing description, and all the improvements and modifications shall fall within the scope of protection of the appended claims of the present application.
