- the vaporization assembly 2 may further include electrode members 24 , and there may be two electrode members 24 .
- the two electrode members 24 may be electrically connected to the two conductive connection portions 223 on the heating component 22 respectively in a one-to-one correspondence manner.

- a shape of the vaporization cavity 214 is different.
- the vaporization cavity 214 may be substantially in a shape of a rectangular with rounded corners.

- the airflow of the first embodiment is smoother.
- a structure of an inlet adaptation section and a structure of the air outlet channel 213 are substantially the same, but a design of the vaporization cavity 214 is different.
- a main difference is that the airflow enters the vaporization cavity 214 from the adaptation section (the second connection portion 2142 ) at a different velocity horizontal angle, and a shape of the adaptation section (the second connection portion 2142 ) from the vaporization cavity 214 to the air outlet channel 213 is different, so that uniformity and fluidity of the airflow are different.
- inhalation resistance of the airflow channel in the first embodiment and the second embodiment is mainly caused by two parts: the air inlet channel and the adaptation section (the second connection portion 2142 ) entering the vaporization cavity 214 ; and the inhalation resistance of the first embodiment is 713.5 Pa, and the inhalation resistance of the second embodiment is 918.3 Pa.
- the inhalation resistance of the second embodiment increases by 28.7%.
- a main reason for the small inhalation resistance of the first embodiment is that a cross-sectional area of an inlet channel of the vaporization cavity 214 is relatively large. The local resistance loss of the air entering the vaporization cavity 214 is small, and the airflow channel at the outlet of the vaporization cavity 214 is smoother, generating a small vortex and less resistance loss.
- a vortex in an area 1 causes an increase in the inhalation resistance of the airflow channel and intensifies condensation of vapor.
- a vortex in an area 2 causes a vaporization medium to not be taken away in time, and a temperature of the heating element is too high.
- the two air guide grooves 2121 of the vaporization cavity 214 of the second embodiment are on the same straight line, after the air enters the vaporization cavity 214 from the two air inlets, a “stagnation area” appears at the heating element in the middle, a large vortex (as shown in a dotted box in the foregoing figure) is generated. Most of the airflow is not fully diffused in the vaporization cavity 214 , and directly flows out to the air outlet channel.
- the air guide grooves 2121 of the first embodiment are staggered with each other, so that the air enters the vaporization cavity 214 and fully diffuses. Velocity distribution in a heating element area is more uniform, and the air may be fully mixed with the vaporized liquid vaporization medium and then flow out of the vaporization cavity 214 .
- the airflow in the first embodiment is more uniformly mixed and the flow is smoother.
- the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise.
- the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.

In this embodiment, anair inlet 2312 may be provided on thebase 23. Specifically, theair inlet 2312 may be provided on thebase body 231, and there may be twoair inlets 2312. The twoair inlets 2312 may be distributed on a short axis of thebase body 231, and are in communication with theair storage cavity 215 respectively. In this embodiment, a first throughhole 2313 may further be provided on thebase body 231, and there may be two first throughholes 2313. The two first throughholes 2313 may be provided at intervals, so that twoelectrode members 24 may be mounted on the two first throughholes 2313 in a one-to-one correspondence manner. In this embodiment, two second throughholes 2313 may further be provided on thebase body 231.

The twomagnetic members 25 may be mounted in the two second throughholes 2314 in a one-to-one correspondence manner, and may attract and fix the entire vaporizer with the power supply assembly. -
FIG. 10 toFIG. 12 show the second embodiment of the electronic vaporization device of the present invention, which is different from the first embodiment in that the twoair guide grooves 2121 are provided in parallel and are located on a straight line. In addition, a shape of thevaporization cavity 214 is different. In this embodiment, thevaporization cavity 214 may be substantially in a shape of a rectangular with rounded corners. The first connection portion 2141 may be a plane, thesecond connection portion 2142 may be an arc surface, and thethird connection portion 2143 may be a plane. - After the airflow is guided to the
vaporization surface 214 by theair guide structure 2120, a flow direction of the airflow may be changed by using vaporization cavities of different shapes. Compared with the airflow of the second embodiment, the airflow of the first embodiment is smoother. In the first embodiment and the second embodiment, a structure of an inlet adaptation section and a structure of theair outlet channel 213 are substantially the same, but a design of thevaporization cavity 214 is different. A main difference is that the airflow enters thevaporization cavity 214 from the adaptation section (the second connection portion 2142) at a different velocity horizontal angle, and a shape of the adaptation section (the second connection portion 2142) from thevaporization cavity 214 to theair outlet channel 213 is different, so that uniformity and fluidity of the airflow are different. Specifically, reference may be made to comparative analysis of a pressure field and a velocity field of the first embodiment and the second embodiment. - As shown in
FIG. 13 andFIG. 14 , inhalation resistance of the airflow channel in the first embodiment and the second embodiment is mainly caused by two parts: the air inlet channel and the adaptation section (the second connection portion 2142) entering thevaporization cavity 214; and the inhalation resistance of the first embodiment is 713.5 Pa, and the inhalation resistance of the second embodiment is 918.3 Pa. Compared with the inhalation resistance of the first embodiment, the inhalation resistance of the second embodiment increases by 28.7%. A main reason for the small inhalation resistance of the first embodiment is that a cross-sectional area of an inlet channel of thevaporization cavity 214 is relatively large. The local resistance loss of the air entering thevaporization cavity 214 is small, and the airflow channel at the outlet of thevaporization cavity 214 is smoother, generating a small vortex and less resistance loss. - As shown in
FIG. 15 andFIG. 16 , compared with the first embodiment, there are two relatively large vortex areas in thevaporization cavity 214 of the second embodiment. A vortex in anarea 1 causes an increase in the inhalation resistance of the airflow channel and intensifies condensation of vapor. A vortex in anarea 2 causes a vaporization medium to not be taken away in time, and a temperature of the heating element is too high. - As shown in
FIG. 17 andFIG. 18 , because the twoair guide grooves 2121 of thevaporization cavity 214 of the second embodiment are on the same straight line, after the air enters thevaporization cavity 214 from the two air inlets, a “stagnation area” appears at the heating element in the middle, a large vortex (as shown in a dotted box in the foregoing figure) is generated. Most of the airflow is not fully diffused in thevaporization cavity 214, and directly flows out to the air outlet channel. Theair guide grooves 2121 of the first embodiment are staggered with each other, so that the air enters thevaporization cavity 214 and fully diffuses. Velocity distribution in a heating element area is more uniform, and the air may be fully mixed with the vaporized liquid vaporization medium and then flow out of thevaporization cavity 214. - Based on the foregoing analysis, it may be learnt that compared with that in the second embodiment, the airflow in the first embodiment is more uniformly mixed and the flow is smoother.
- While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.
- The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
