A sealing member 260 is arranged in the power supply mechanism 200, and at least a part of an internal space of the power supply mechanism 200 is separated by the sealing member 260 to form the receiving cavity 270. In the preferred implementation shown in FIG. 1, the sealing member 260 is constructed to extend in a cross section direction of the power supply mechanism 200, and is made of a flexible material, so as to prevent the liquid substrate, which seeps from the vaporizer 100 to the receiving cavity 270, from flowing to components such as a controller 220 and a sensor 250 in the power supply mechanism 200.

FIG. 2 shows a specific schematic structural diagram of the vaporizer 100 in an embodiment of the present application. In the embodiment, the vaporizer 100 as a whole is of an elongate flat shape, and has a proximal end 110 and a distal end 120, which are opposite each other in the length direction. When in use, the proximal end 110 serves as an end used by a user to vape by the mouth, and the distal end 120 is an end that is received in the power supply mechanism 200. An external construction includes:

• • a main housing 10, which is of a hollow cylindrical shape, with an end part close to the distal end 120 being an opening; and
  • an end cover 20, which is disposed at the distal end 120 of the vaporizer 100, and closes the opening of the main housing 10, such that the main housing and the end cover together form a completed housing of the vaporizer 100.

Furthermore, as shown in FIG. 2, the second electrical contact 21 of the vaporizer 100 penetrates the interior of the vaporizer from the distal end 120, and is at least partially exposed on a surface of the end cover 20, such that the second electrical contact easily forms an electrically conductive connection with the power supply mechanism 200 when in use. Moreover, an air inlet 22 is further provided at the distal end 120 of the vaporizer 100, and is configured in such a way that external air enters the vaporizer 100 when the user vapes.

Moreover, in another optional implementation, the vaporizer 100 is further provided with a magnetic attraction element (not shown in the figures), which penetrates the interior of the vaporizer from the distal end 120, and when in use, the magnetic attraction element magnetically attracts the power supply mechanism 200, such that the vaporizer 100 is stably held in the power supply mechanism 200.

Furthermore, FIG. 3 to FIG. 5 show a schematic diagram of an internal structure of the vaporizer 100 in FIG. 2, and a schematic exploded diagram of some components thereof. As shown in FIG. 3 and FIG. 5, the vaporizer 100 further includes:

• • a vapor output pipe 11, which extends in an axial direction of the main housing 10, with an upper end thereof being in airflow communication with an inhalation opening A at an upper end of the main housing 10 to output an aerosol generated in the vaporizer 100 to the inhalation opening A for inhalation;
  • a liquid storage cavity 12, which is formed by a space between the vapor output pipe 11 and an inner wall of the main housing 10, and is configured to store a liquid substrate; and
  • a vaporization assembly 30, which is configured to draw the liquid substrate from the liquid storage cavity 12 by capillary infiltration, and heat and vaporize the drawn liquid substrate to generate an aerosol for inhalation. Specifically, the vaporization assembly 30 includes a liquid guide element 31 and a heating element 32, which at least partially surrounds the liquid guide element 31. As shown in FIG. 3 and FIG. 4, the liquid guide element 31 is constructed to extend in a width direction of the main housing 10, two ends thereof being exposed or being in fluid communication with the liquid storage cavity 12. The liquid substrate in the liquid storage cavity 12 is absorbed by the two ends of the liquid guide element 31 and then transferred inward along an arrow R1 as shown in FIG. 4. The heating element 32 surrounds or is wound on at least a part of the liquid guide element 31, and is configured to heat at least a part of the liquid substrate in the liquid guide element 31 to generate an aerosol for inhalation.

In an optional implementation, the liquid guide element 31 may be made of or include a porous ceramics body, fiber wool, a fiber rope, a porous material, etc. The heating element 32 may be made of a resistive metal material, for example, iron, nickel, chromium or an alloy of them, etc.

Further referring to FIG. 3 to FIG. 5, the rigid upper holder 40 and the flexible lower holder 50 are assembled in the main housing 10 to fix the vaporization assembly 30. Specifically referring to FIG. 3 and FIG. 4, a clamping arm 44 extending out is arranged on the upper holder 40, and the vaporization assembly 30 abuts against or is clamped on the lower holder 50 by the clamping arm 44. Moreover, a first concave cavity 43 facing the lower holder 50 is provided in the upper holder 40, and a second concave cavity 52 facing the upper holder 40 is provided in the lower holder 50, such that, after assembly, the first concave cavity 43 and the second concave cavity 52 together form a vaporization cavity, which encircles or surrounds the vaporization assembly 30 and accommodates an aerosol that is released and generated.

In a preferred implementation shown in FIG. 4, a carrying groove 51 that is opposite an end part of the liquid guide element 31 is further provided in the lower holder 50, and is configured to carry a liquid substrate that seeps from the end part of the liquid guide element 31.

To facilitate the sealing of a gap between the upper holder 40 and the liquid storage cavity 12, the vaporizer 100 further includes a sealing element 60, which is at least partially located between the upper holder 40 and the liquid storage cavity 12, so as to seal the liquid storage cavity 12. The liquid guide element 31 and the heating 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 the vapor output pipe 11 through a first insertion hole 61 in the sealing element 60.

Furthermore, a bottom wall of the second concave cavity 52 of the lower holder 50 is further provided with a hole 53, which is opposite the air inlet 22 in the end cover 20, and external air entering from the air inlet hole 22 enters the vaporization cavity through the hole 53.

With regard to a design of an outputted airflow of an aerosol, the upper holder 40 is provided with a second insertion hole 41. The end part of the vapor output pipe 11 penetrates the first insertion hole 61 in the sealing element 60 and is then further inserted into the second insertion hole 41. Two sides of the upper holder 40 in the thickness direction are provided with output channels 45, such that the aerosol within the vaporization cavity is outputted to the vapor output pipe 11 along an arrow R2 shown in FIG. 3 and FIG. 6.

To cooperate with the vaporization assembly 30 for liquid guide, the sealing element 60 is provided with a first liquid guide hole 62 for the liquid substrate to flow toward the upper holder 40. The upper holder 40 is further provided with a second liquid guide hole 42. When in use, the liquid substrate in the liquid storage cavity 12 sequentially passes through the first liquid guide hole 62 and the second liquid guide hole 42, and is transferred to the vaporization assembly 30 and is absorbed and vaporized.

Furthermore, in a preferred implementation shown in FIG. 8 and FIG. 9, a transversely extending blocking portion 46 is arranged in the upper holder 40, and the blocking portion delimits the first concave cavity 43. A projection of the blocking portion 46 in the longitudinal direction of the vaporizer 100 covers the heating 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 the heating element 32; moreover, the blocking portion can also block a condensate and the like within the vaporization cavity, preventing same from directly flowing toward the vapor output pipe 11.

Further referring to the preferred embodiment shown in FIG. 6 to FIG. 9, a lower end part of the vapor output pipe 11 that is inserted into the upper holder 40 is provided with at least one notch 111, and the upper holder 40 is provided with a ridge 47, which fits the notch 111. Specifically, in FIG. 8, the ridge 47 extends in the longitudinal direction of the vaporizer 100, and has two portions having different widths, i.e. a first portion 471 that is close to the vapor output pipe 11, and a second portion 472 that is relatively away from the vapor output pipe 11. The first portion 471 has a smaller width than the second portion 472, and the first portion 471 is thinner than the second portion 472 in terms of form. In the implementation shown in FIG. 9, the first portion 471 has a width of approximately 0.3 mm to 0.8 mm, and the second portion 472 has a width of approximately 0.8 mm to 1.5 mm. The notch 111 has a width of approximately 1.2 mm.

The form after assembly is as shown in FIG. 9. The first portion 471 at least partially extends into the notch 111 at the lower end of the vapor output pipe 11, and the second portion 472 is located outside the notch 111. Moreover, after assembly, two side surfaces of the first portion 471 are not in contact with two side surfaces of the notch 111, and according to FIG. 9, there is spacing kept between the two side surfaces of the first portion 471 and the two side surfaces of the notch 111. Furthermore, the spacing is controlled smaller than 2 mm, so as to form the capillary channel 80 that longitudinally extends. Therefore, during use, when an aerosol condensate formed on an inner wall of the vapor output pipe 11 falls or flows downward to a lower end under gravity, the condensate at the lower end of the vapor output pipe 11 is guided downward into the holder 40 by a capillary adsorbing and guiding acting force of the capillary channel 80, so as to avoid the condensate from accumulating at the inner wall or the lower end of the vapor 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 the ridge 47 is connected to the blocking portion 46, such that the condensate that is drawn and guided by the capillary channel 80 drips onto the blocking portion 46. In the preferred implementation shown in FIG. 8 and FIG. 9, the blocking portion 46 is arc-shaped, and thus the condensate that subsequently flows and falls onto the blocking portion 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 in FIG. 9.

In the preferred implementation shown in FIG. 8, the extension length of the second portion 472 is greater than that of the first portion 471. In the implementation, the length of the second portion 472 is approximately 3 mm, and the length of the first portion 471 is approximately 2 mm.

Furthermore, in another optional implementation, the ridge 47 further includes a flow guide groove 473, which is delimited by the second portion 472 and a wall of the upper holder 40. In FIG. 8, there is the flow guide groove 473 at a portion where the second portion 472 is combined with the upper holder 40, and the flow guide groove 473 further facilitates quickly guiding the condensate, which is transferred by the capillary channel 80, onto the blocking portion 46, avoiding the condensate from being adsorbed and held in the capillary channel 80 between the first portion 471 and the vapor 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 the upper 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 50a that is provided with a ridge 47a. The size of the ridge 47a in FIG. 10 is larger than that of the ridge 47 in FIG. 8. In terms of shape, the ridge 47a is also provided with a first portion 471a and a second portion 472a, moreover, a longitudinally extending flow guide groove 473a is formed at a portion where the second portion 472a is joined to a wall 400a of the upper holder 40a, transferring the condensate downward more quickly.

The first portion 471a is closer to the center than the first portion 471, and is also not in contact with the wall 400a of the upper holder 40a, such that an accommodating space 4711a is formed between the first portion 471a and the wall. After assembly, the notch 111 at the lower end of the vapor output pipe 11 extends into the accommodating space 4711a, such that the space of the capillary channel 80 between the ridge 47a and the vapor 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 the first portion 471a still extends into the notch 111 of the vapor output pipe 11, and certain spacing is kept, forming the capillary channel that adsorbs and transfers the condensate at the lower end of the vapor output pipe 11.

FIG. 11 shows a schematic diagram of a vapor output pipe 11a that is manufactured in a main housing 10a in another embodiment. In the implementation shown in FIG. 11, the cross-sectional shape of the vapor output pipe 11a is a flat shape, and preferably an elliptical shape. Moreover, the elliptical shape takes the width direction of the main housing 10a as a long axis B1 and the thickness direction of the main housing 10a as a short axis B2, such that the condensate in the vapor output pipe 11a 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 11a is provided with a second notch 112a close to at least one side of the main housing 10a in the width direction. By using the second notch 112a, 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 the first notch 111a, and is then guided into the vaporization cavity more easily under the cooperation of the ridge 47. Certainly, to further fit the elliptical or flat vapor output pipe 11a, the first insertion hole 61 and the second insertion hole 41 above are also of a flat or elliptical shape for fitting. Similarly, in conjunction with the above implementations, the position of the ridge 47 needs to be adjusted to fit the first notch 111a to form the capillary channel, so as to guide the aerosol condensate.

In a preferred implementation shown in FIG. 11, the first notch 111a has a width greater than that of the second notch 112a. In the implementation, the width of the first notch 111a is approximately 2.4 mm, and the width of the second notch 112a 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.
