Further, in the preferred implementation shown in FIG. 1, a charging interface 240 is provided in the other end of the power supply mechanism 200 facing away from the receiving cavity 270, and used for supplying power to the battery cell 210.

FIGS. 2 to 5 are schematic structural diagrams of an embodiment of the vaporizer 100 in FIG. 1. The vaporizer 100 includes

    • a main housing 10. As shown in FIGS. 2 to 3, the main housing 10 is substantially in a flat cylinder shape, and certainly, a hollow interior of the main housing 10 is a necessary functional device for storing and vaporizing the liquid substrate. The main housing 10 has a near end 110 and a far end 120 opposite to each other in the length direction. According to requirements for common use, the near end 110 is configured as an end for a user to inhale the aerosol, and a suction nozzle A for the user to inhale is provided at the near end 110. The far end 120 is used as an end coupled with the power supply mechanism 200, and the far end 120 of the main housing 10 is an opening on which a detachable end cap 20 is mounted. The opening structure is used for mounting necessary functional components inside the main housing 10.

Further, in a specific implementation shown in FIGS. 2 to 4, the second electrical contacts 21 penetrate into the vaporizer 100 from a surface of the end cap 20, so that at least parts of the second electrical contacts 21 are exposed outside the vaporizer 100, so as to be able to make contact with the first electrical contacts 230 to conduct electricity. At the same time, the end cap 20 is further provided with a first air inlet 23, which is used for allowing outside air to enter the vaporizer 100 during inhalation.

Certainly, further referring to FIG. 3, assembling grooves 22 for accommodating the second electrical contacts 21 are formed in the surface of the end cap 20, so that after assembly, the second electrical contacts 21 are aligned with the surface of the end cap 20.

Further, FIGS. 3 to 5 show a schematic diagram of an internal structure of the vaporizer 100 in FIG. 2 and schematic exploded views of part of components of the vaporizer 100 in FIG. 2. According to FIGS. 3 to 5, the vaporizer 100 further includes:

    • a smoke output pipe 11, extending in an axial direction of the main housing 10, where an upper end of the smoke output pipe 11 is in airflow communication with a suction nozzle A located at an upper end of the main housing 100, so as to output the aerosol generated in the vaporizer 100 to the suction nozzle A for inhalation;
    • a liquid storage cavity 12, formed by a space between the smoke output pipe 11 and an inner wall of the main 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 a liquid guide element 30, and a heating element 40 at least partially surrounding the liquid guide element 30. According to FIGS. 3 to 5, the liquid guide element 30 is configured to extend in a width direction of the main housing 10 with two ends exposed or in fluid communication with the liquid storage cavity 12, and the liquid substrate in the liquid storage cavity 12 is sucked by the two ends of the liquid guide element 30 along arrow R1 in FIG. 3 and then transferred inwards. At least part of the heating element 40 surrounding or winding the liquid guide element 30 is used for heating at least part of the liquid substrate in the liquid 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 the heating 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 the main housing 10 through a rigid upper support 50 and a flexible lower support 60. Specifically, referring to FIGS. 3 to 5, the upper support 50 and the lower support clamp the liquid guide element 30 from an upper side and a lower side, respectively, so that the liquid guide element 30 is kept between the upper support 50 and the lower support 60.

For ease of sealing a gap between the upper support 50 and the liquid storage cavity 12, the vaporizer 100 further includes a seal element 70, at least part of the seal element 70 is located between the upper support 50 and the liquid storage cavity 12 to seal the liquid storage cavity 12. After assembly, the seal element 70 at least partially covers a surface of the upper support 50, so that the seal element 70 is supported by the upper support 50. A first insertion hole 72 for insertion of the smoke output pipe 11 is provided in the seal 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 the liquid guide element 30 and/or the heating element 40. According to FIG. 5, the vaporization chamber is defined between the upper support 50 and the lower support 60. Specifically, the upper support 50 is provided with a first cavity 53 close to the heating element 40, and the lower support 60 is provided with a second cavity 63 close to the heating element 40, so that spaces of the first cavity 53 and the second cavity 63 jointly form the vaporization chamber for aerosol release. At the same time, a second air inlet 62 for air to enter the vaporization chamber is provided in the lower support 60. A first insertion hole 52 for connection of the smoke output pipe 11 is provided in the upper support 50. Thus, during inhalation, the outside air sequentially passes through the first air inlet 23 in the end cap 20 and the second air inlet 62 to enter the vaporization chamber, and carries the generated aerosol to be output from the smoke 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 the upper support 50. Thus, the liquid substrate in the liquid 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 the liquid guide element 30.

Specifically, in the implementation, further referring to FIG. 6, the liquid guide element 30 includes first portions 31 close to two side ends in the length direction, and after assembly, the first portions 31 are opposite to the second liquid guide holes 51, so that the liquid substrate is sucked by the first portions 31. The liquid guide element 30 further includes a second portion 32 close to the center, and the heating element 40 surrounds the second portion 32. After assembly, the second portion 32 is surrounded by the vaporization chamber.

Further, porous body materials 80 are provided in the second liquid guide holes 51. The porous body materials 80 are prepared from sponge bodies, fiber cotton, etc., for example. Or in other variant implementations, for example, the porous body materials 80 can include porous foam, porous polyurethane, porous ceramic bodies, etc. After assembly, the porous body materials 80 abut against the first portions 31 of the liquid guide element 30. The porous body materials 80 are used for adjusting an amount of a liquid substrate transferred from the second liquid guide holes 51 to the first portions 31 of the liquid guide element 30, so as to avoid the liquid substrate from being quickly and excessively sucked by the liquid guide element 30, thus slowing down oil frying in the heating process.

Further, in a more preferred implementation, referring to FIGS. 6 to 7, the lower support 60 as a whole is substantially shaped like a hollow cup and the like. Two support walls 61 sequentially arranged in the width direction are provided in the lower support 60. Certainly, the support walls 61 extend in the longitudinal direction of the main housing 10, and the liquid guide element 30 is supported and held by the support walls 61 from the lower side. Moreover, the above second cavity 63 is defined or formed between the two support walls 61.

In FIGS. 5 to 7, the two ends of the assembled liquid guide element 30 abut against side walls of the lower support 60 in the width direction, respectively. At the same time, the lower support 60 is further internally provided with liquid temporary storage cavities 64 defined between the support walls 61 and the side walls of the lower support 60. After the liquid guide element 30 is assembled, the first portions 31 are located in the liquid temporary storage cavities 64 in the longitudinal direction and surrounded by the liquid temporary storage cavities 64. The liquid temporary storage cavities 64 are used for temporarily storing a surplus or excess liquid substrate transferred to the first portions 31, or storing the surplus or excess liquid substrate seeping from the first portions 31. Thus, the excess liquid substrate is prevented from being transferred to the second portion 32, thus slowing down oil frying. After a liquid substrate in the second portion 32 is consumed, the liquid substrate in the liquid temporary storage cavities 64 can further be sucked by the first portions 31 and then replenished into the second portion 32.

In a more preferred implementation, air pressure balance channels 641 penetrating from inner walls of the liquid temporary storage cavities 64 towards a surface of the end cap 20 are further provided on the lower support 60. Thus, the air pressure balance channels 641 communicate with the first air inlet 23. Thus, whether in an inhalation state or a non-inhalation state, an air pressure in the liquid temporary 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 the second 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 the first portions 31 to be transferred to the second portion 32, causing the liquid substrate in the second portion 32 to be excessive, resulting in oil frying. Thus, after the above liquid temporary storage cavities 64 communicate with the first air inlet 23 through the air pressure balance channels 641, in the inhalation process, the air pressure in the liquid temporary storage cavities 64 is also decreased to the same negative pressure as the vaporization chamber. Thus, the second portion 32 can only suck the liquid substrate from the first portions 31 through capillary force drive, so that saturation of the liquid substrate sucked in the second 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 the support walls 61 adjacent to the liquid temporary storage cavities 64. The grooves 611 are used for guiding the liquid substrate seeping from a surface of the first portion 31 into the liquid temporary storage cavities 64.

Further referring to FIG. 8, pin fixing grooves 65 are provided in a side of the lower support 60 facing the end cap 20 to allow pin portions 41 of the heating element 40 to penetrate through the lower support 60 from the interior of the second cavity 63 and then to be fixedly held in the pin fixing grooves 65 so as to conduct electricity at the second electrical contacts 21. At the same time, after assembly, ends of the air pressure balance channels 641 facing the end cap 20 are always kept in an opening state.

In a more preferred implementation, referring to FIG. 9, after assembly, the smoke output pipe 11 penetrates through a second insertion hole 52 of the upper support 50, and the smoke output pipe 11 is provided with an air inlet end 111 at least partially exposed in the first cavity 53 of the upper support 50. The air inlet end 111 of the smoke output pipe 11 is provided with notches 112 located in two sides in the width direction. Protrusions 54 are provided on an inner wall of the first cavity 53 of the upper support 50. After assembly, an outer side wall of the air inlet end 111 of the smoke output pipe 11 abuts against the protrusions 54, so that aerosol condensate in the notches 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 the smoke 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.
