- Alternatively, in other variant implementations, the fluid-
permeable heating element 40 may adopt a porous heating film that allows fluid to penetrate pores as described in the patent No. CN201510854348.1. Alternatively, in more implementations, the fluid-permeable heating element 40 may be a perforated plate, or a planar track, for example, a heating element that is a sheet after being unfolded and that has a through hole set provided by the applicant in the patent No. CN209234993U. - To facilitate the second
electrical contact 21 to smoothly abut against the firstconductive connection portion 41 and the secondconductive connection portion 43, correspondingly, theliquid guide element 30 shown inFIG. 14 has anavoidance portion 31 configured to avoid the secondelectrical contact 21. Specifically, theavoidance portion 31 is a recess formed on theliquid guide element 30. After assembly, the secondelectrical contact 21 penetrates theavoidance portion 31 and then abuts against the fluid-permeable heating element 40. - Certainly, further according to an implementation, the
liquid guide element 30 has afirst surface 310 and asecond surface 320 that face away from each other in the longitudinal direction. In use, thesecond surface 320 attaches to the sealingbase 70 to provide a stop, and thefirst surface 310 is configured for combination with the fluid-permeable heating element 40. Certainly, the fluid-permeable heating element 40 needs to cover or block theavoidance portion 31. Specifically, mainly the firstconductive connection portion 41 and the secondconductive connection portion 43 cover or block theavoidance portion 31, so that the secondelectrical contact 21 can penetrate theavoidance portion 31 and abut against the firstconductive connection portion 41 and the secondconductive connection portion 43. - In another variant implementation shown in
FIG. 15 , aliquid guide element 30 a is substantially a square block, and anavoidance portion 31 a is a through hole penetrating from asecond surface 320 a to afirst surface 310 a. - Alternatively, in other more variant implementations, the
liquid guide element 30/30 a may be in another regular or irregular shape; and theavoidance portion 31/31 a may be a structure of a hole or a groove. - Further, referring to
FIG. 8 andFIG. 9 , a top wall of thesecond compartment 54 of thebracket 50 has an abuttingportion 56; and thesecond compartment 54 has afirst opening 541 formed between the abuttingportion 56. After assembly, the fluid-permeable heating element 40 is fixed by abutting against the abuttingportion 56. In addition, the fluid-permeable heating element 40 crosses thefirst opening 541. Certainly, during specific assembly, upper surfaces of the firstconductive connection portion 41 and the secondconductive connection portion 43 of the fluid-permeable heating element 40 abut against the abuttingportion 56. - According to
FIG. 8 andFIG. 9 , the abuttingportion 56 is aligned with theavoidance portion 31 of theporous body 30 or the secondelectrical contact 21 in the longitudinal direction. - Further, according to
FIG. 6 toFIG. 11 , thesecond compartment 54 defined by thebracket 50 is selectively in communication with thefirst compartment 12 in themain housing 10, to selectively receive the liquid substrate flowing from thefirst compartment 12, thereby preventing the liquid substrate in thefirst compartment 12 from flowing to the vaporization assembly before thevaporizer 100 is used, that is, implementing the “oil-core separation”. Specifically, -
- a
notch 55 is provided on a wall of thesecond compartment 54 defined by thebracket 50 adjacent to theliquid guide channel 51, and the liquid substrate flowing from theliquid guide channel 51 enters thesecond compartment 54 through thenotch 55.
- a
- The sealing
base 70 has a blockingarm 71 extending toward thenotch 55, and after assembly, the blockingarm 71 plugs or blocks or seals thenotch 55. The blockingarm 71 can further drive or push the blockingarm 71 to move or tilt through a moving operation of the secondelectrical contact 21, and further open or communicate with thenotch 55, so that the liquid substrate flowing from theliquid guide channel 51 can enter thesecond compartment 54. - A specific shape of the second
electrical contact 21 is, referring toFIG. 12 , generally cylindrical or needle-like, and the second electrical contact has afirst section 211 and asecond section 212 sequentially arranged in the longitudinal direction. An outer diameter of thefirst section 211 is less than that of thesecond section 212. The secondelectrical contact 21 can move in the longitudinal direction, and has a first position as shown inFIG. 2 ,FIG. 6 , andFIG. 9 , and a second position as shown inFIG. 10 andFIG. 11 . Specifically, -
- at the first position, the second
electrical contact 21 at least partially protrudes relative to the surface of theend cap 20. At the first position, the secondelectrical contact 21 is kept in theend cap 20, but a front end of thefirst section 211 of the secondelectrical contact 21 does not abut against or contact the fluid-permeable heating element 40, and is kept at a distance with the fluid-permeable heating element 40. In addition, at the first position, thesecond section 212 of the secondelectrical contact 21 does not abut against or contact the blockingarm 71, and the blockingarm 71 is in a state of sealing or blocking thenotch 55.
- at the first position, the second
- In use, the user pushes the second
electrical contact 21, by pressing or in other manners, to move in the longitudinal direction from the first position by a specific distance to the second position, so that at the second position, the front end of thefirst section 211 abuts against the fluid-permeable heating element 40. During movement, thesecond section 212 of the secondelectrical contact 21 with a larger outer diameter pushes or drives the blockingarm 71 to move or bend toward theliquid guide channel 51, to further at least partially open thenotch 55 and form communication shown inFIG. 11 . In this case, the liquid substrate in thefirst compartment 12 can flow along the inside of theliquid guide channel 12, and enters thesecond compartment 54 through thenotch 55 to be absorbed by theliquid guide element 30, as shown by an arrow RI inFIG. 4 andFIG. 11 . - Further, referring to
FIG. 12 , the secondelectrical contact 21 further has apositioning engaging protrusion 213 configured to provide a stop or positioning retention for the secondelectrical contact 21 at the first position and the second position. Specifically, when the secondelectrical contact 21 is at the first position, thepositioning engaging protrusion 213 generally abuts against a surface of a mounting hole accommodating the secondelectrical contact 21 of theend cap 20, for example, as shown inFIG. 6 . When the user presses the secondelectrical contact 21 with force, an external force is enough to overcome a friction force between thepositioning engaging protrusion 213 and theend cap 20, so that thepositioning engaging protrusion 213 is engaged into the mounting hole of theend cap 20 and move, until thepositioning engaging protrusion 213 abuts against the sealingbase 70 and forms a stop at the second position, as shown inFIG. 11 . - According to
FIG. 9 , the outer diameter of thefirst section 211 is smaller, and when the secondelectrical contact 21 is at the first position, thefirst section 211 abuts against or contacts the blockingarm 71 or the like, but cannot drive the blockingarm 71 to move or bend. - In addition, according to a preferable implementation shown in
FIG. 10 , a tail end of the secondelectrical contact 21 is flush with the surface of theend cap 20 at the second position. In other words, compared to the first position, the secondelectrical contact 21 does not protrude relative to the surface of theend cap 20 at the second position. - To facilitate movement or deformation of the blocking
arm 71 under driving of the secondelectrical contact 21, further, referring toFIG. 16 , ahole 72 configured to allow the secondelectrical contact 21 to penetrate is provided on the sealingbase 70, and the blockingarm 71 is shaped and constructed with a protrudingportion 711. The protrudingportion 711 at least partially covers thehole 72 in the longitudinal direction, and is further configured to allow the secondelectrical contact 21 to actuate the protrudingportion 711 during movement, causing the blockingarm 71 to move or deform. In a more preferred implementation, the protrudingportion 711 is obliquely arranged. - It should be noted that, the specification of this application and the accompanying drawings thereof illustrate preferred embodiments of this application, but are not limited to the embodiments described in this specification. Further, 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 protection scope of the appended claims of this application.
