At the same time, theend cap 20 is further provided with afirst air inlet 23, which is used for allowing outside air to enter thevaporizer 100 during inhalation. - Certainly, further referring to
FIG. 3 , assemblinggrooves 22 for accommodating the secondelectrical contacts 21 are formed in the surface of theend cap 20, so that after assembly, the secondelectrical contacts 21 are aligned with the surface of theend cap 20. - Further,
FIGS. 3 to 5 show a schematic diagram of an internal structure of thevaporizer 100 inFIG. 2 and schematic exploded views of part of components of thevaporizer 100 inFIG. 2 . According toFIGS. 3 to 5 , thevaporizer 100 further includes: - a
smoke output pipe 11, extending in an axial direction of themain housing 10, where an upper end of thesmoke output pipe 11 is in airflow communication with a suction nozzle A located at an upper end of themain housing 100, so as to output the aerosol generated in thevaporizer 100 to the suction nozzle A for inhalation; - a
liquid storage cavity 12, formed by a space between thesmoke output pipe 11 and an inner wall of themain housing 10, and used for storing the liquid substrate; and - a vaporization assembly, used for sucking the liquid substrate from the
liquid storage cavity 12 through capillary infiltration, and heating and vaporizing the sucked liquid substrate to generate the aerosol for inhalation. Specifically, the vaporization assembly includes aliquid guide element 30, and aheating element 40 at least partially surrounding theliquid guide element 30. According toFIGS. 3 to 5 , theliquid guide element 30 is configured to extend in a width direction of themain housing 10 with two ends exposed or in fluid communication with theliquid storage cavity 12, and the liquid substrate in theliquid storage cavity 12 is sucked by the two ends of theliquid guide element 30 along arrow R1 inFIG. 3 and then transferred inwards. At least part of theheating element 40 surrounding or winding theliquid guide element 30 is used for heating at least part of the liquid substrate in theliquid guide element 30 to generate the aerosol for inhalation. - In an optional implementation, the
liquid guide element 30 can be made of or include a porous ceramic body, fiber cotton, a fiber rope, a porous material, etc.; and theheating element 40 can be made of a resistive metal material, such as iron, nickel, chromium, or alloys thereof. - Further, referring to
FIGS. 3 to 5 , the vaporization assembly is assembled and fixed in themain housing 10 through a rigidupper support 50 and a flexiblelower support 60. Specifically, referring toFIGS. 3 to 5 , theupper support 50 and the lower support clamp theliquid guide element 30 from an upper side and a lower side, respectively, so that theliquid guide element 30 is kept between theupper support 50 and thelower support 60. - For ease of sealing a gap between the
upper support 50 and theliquid storage cavity 12, thevaporizer 100 further includes aseal element 70, at least part of theseal element 70 is located between theupper support 40 and theliquid storage cavity 12 to seal theliquid storage cavity 12. After assembly, theseal element 70 at least partially covers a surface of theupper support 50, so that theseal element 70 is supported by theupper support 50. Afirst insertion hole 72 for insertion of thesmoke output pipe 11 is provided in theseal element 70. - For generation, release and output of the aerosol, the
vaporizer 100 internally forms a vaporization chamber at least partially surrounding the vaporization assembly, and specifically, at least partially surrounding theliquid guide element 30 and/or theheating element 40. According toFIG. 5 , the vaporization chamber is defined between theupper support 50 and thelower support 60. Specifically, theupper support 50 is provided with afirst cavity 53 close to theheating element 40, and thelower support 60 is provided with asecond cavity 63 close to theheating element 40, so that spaces of thefirst cavity 53 and thesecond cavity 63 jointly form the vaporization chamber for aerosol release. At the same time, asecond air inlet 62 for air to enter the vaporization chamber is provided in thelower support 60. Afirst insertion hole 52 for connection of thesmoke output pipe 11 is provided in theupper support 50. Thus, during inhalation, the outside air sequentially passes through thefirst air inlet 23 in theend cap 20 and thesecond air inlet 62 to enter the vaporization chamber, and carries the generated aerosol to be output from thesmoke output pipe 11. - On transfer paths of the liquid substrate, first liquid guide holes 71 are provided in the
seal element 70, and second liquid guide holes 51 are provided in theupper support 50. Thus, the liquid substrate in theliquid storage cavity 12 sequentially passes through the first liquid guide holes 71 and the second liquid guide holes 51 to be transferred to and sucked by theliquid guide element 30. - Specifically, in the implementation, further referring to
FIG. 6 , theliquid guide element 30 includesfirst portions 31 close to two side ends in the length direction, and after assembly, thefirst portions 31 are opposite to the second liquid guide holes 51, so that the liquid substrate is sucked by thefirst portions 31. Theliquid guide element 30 further includes asecond portion 32 close to the center, and theheating element 40 surrounds thesecond portion 32. After assembly, thesecond portion 32 is surrounded by the vaporization chamber. - Further,
porous body materials 80 are provided in the second liquid guide holes 51. Theporous body materials 80 are prepared from sponge bodies, fiber cotton, etc., for example. Or in other variant implementations, for example, theporous body materials 80 can include porous foam, porous polyurethane, porous ceramic bodies, etc. After assembly, theporous body materials 80 abut against thefirst portions 31 of theliquid guide element 30. Theporous body materials 80 are used for adjusting an amount of a liquid substrate transferred from the second liquid guide holes 51 to thefirst portions 31 of theliquid guide element 30, so as to avoid the liquid substrate from being quickly and excessively sucked by theliquid guide element 30, thus slowing down oil frying in the heating process. - Further, in a more preferred implementation, referring to
FIGS. 6 to 7 , thelower support 60 as a whole is substantially shaped like a hollow cup and the like. Twosupport walls 61 sequentially arranged in the width direction are provided in thelower support 60. Certainly, thesupport walls 61 extend in the longitudinal direction of themain housing 10, and theliquid guide element 30 is supported and held by thesupport walls 61 from the lower side. Moreover, the abovesecond cavity 62 is defined or formed between the twosupport walls 61. - In
FIGS. 5 to 7 , the two ends of the assembledliquid guide element 30 abut against side walls of thelower support 60 in the width direction, respectively. At the same time, thelower support 60 is further internally provided with liquidtemporary storage cavities 64 defined between thesupport walls 61 and the side walls of thelower support 60. After theliquid guide element 30 is assembled, thefirst portions 31 are located in the liquidtemporary storage cavities 64 in the longitudinal direction and surrounded by the liquidtemporary storage cavities 64. The liquidtemporary storage cavities 64 are used for temporarily storing a surplus or excess liquid substrate transferred to thefirst portions 31, or storing the surplus or excess liquid substrate seeping from thefirst portions 31. Thus, the excess liquid substrate is prevented from being transferred to thesecond portion 32, thus slowing down oil frying. After a liquid substrate in thesecond portion 32 is consumed, the liquid substrate in the liquidtemporary storage cavities 64 can further be sucked by thefirst portions 31 and then replenished into thesecond portion 32. - In a more preferred implementation, air
pressure balance channels 641 penetrating from inner walls of the liquidtemporary storage cavities 64 towards a surface of theend cap 20 are further provided on thelower support 60. Thus, the airpressure balance channels 641 communicate with thefirst air inlet 23. Thus, whether in an inhalation state or a non-inhalation state, an air pressure in the liquidtemporary storage cavities 64 is substantially the same as an air pressure in the vaporization chamber. The problem that due to the impact of inhalation air pressure, the liquid substrate is excessively transferred to thesecond portion 32, resulting in oil frying is avoided. The specific reason lies in that - When a user inhales through the suction nozzle A and a negative pressure is formed, the air pressure in the vaporization chamber will be decreased to the negative pressure; and at this time, if the pressure in the liquid
temporary storage cavities 64 is still not changed and thus greater than that in the vaporization chamber, a pressure difference drives the liquid substrate in thefirst portions 31 to be transferred to thesecond portion 32, causing the liquid substrate in thesecond portion 32 to be excessive, resulting in oil frying. Thus, after the above liquidtemporary storage cavities 64 communicate with thefirst air inlet 23 through the airpressure balance channels 641, in the inhalation process, the air pressure in the liquidtemporary storage cavities 64 is also decreased to the same negative pressure as the vaporization chamber. Thus, thesecond portion 32 can only suck the liquid substrate from thefirst portions 31 through capillary force drive, so that saturation of the liquid substrate sucked in thesecond portion 32 is kept in a suitable state, thus eliminating or slowing down oil frying. - In a preferred implementation shown in
FIG. 7 ,grooves 611 extending in the longitudinal direction are provided in surfaces of thesupport walls 61 adjacent to the liquidtemporary storage cavities 64. Thegrooves 611 are used for guiding the liquid substrate seeping from a surface of thefirst portion 31 into the liquidtemporary storage cavities 64. - Further referring to
FIG. 8 ,pin fixing grooves 65 are provided in a side of thelower support 60 facing theend cap 20 to allowpin portions 41 of theheating element 40 to penetrate through thelower support 60 from the interior of thesecond cavity 63 and then to be fixedly held in thepin fixing grooves 65 so as to conduct electricity at the secondelectrical contacts 21. At the same time, after assembly, ends of the airpressure balance channels 641 facing theend cap 20 are always kept in an opening state. - In a more preferred implementation, referring to
FIG. 9 , after assembly, thesmoke output pipe 11 penetrates through asecond insertion hole 52 of theupper support 50, and thesmoke output pipe 11 is provided with anair inlet end 111 at least partially exposed in thefirst cavity 53 of theupper support 50. Theair inlet end 111 of thesmoke output pipe 11 is provided withnotches 112 located in two sides in the width direction. Protrusions 54 are provided on an inner wall of thefirst cavity 53 of theupper support 50. After assembly, an outer side wall of theair inlet end 111 of thesmoke output pipe 11 abuts against the protrusions 54, so that aerosol condensate in thenotches 112 can be guided onto the protrusions 54 in a contact transfer manner and finally accumulated or kept in the vaporization chamber to prevent too much aerosol condensate from being collected in thesmoke output pipe 11. - Preferred embodiments of this application are given in the description of this application and the accompanying drawings thereof. However, this application is not limited to the embodiments described in this description. Further, a person of ordinary skill in the art may make improvements or modifications according to the foregoing illustrations, and all the improvements and modifications shall fall within the protection scope of the appended claims of this application.
