Specifically, the liquid storage body 10 may include a liquid storage housing 11, a vent tube 13, and a mounting structure 12. The liquid storage housing 11 is in a cylindrical shape with two ends open, and a cross section thereof is roughly in a shape of a racetrack. In other embodiments, the cross section of the liquid storage housing 11 may be in a shape of an ellipse circle, a circle, a rectangle, or may be in another shape.
The vent tube 13 is a circular tube. The vent tube 13 is longitudinally arranged in the liquid storage housing 11 and may be coaxially arranged with the liquid storage housing 11. The inner wall surface of the vent tube 13 defines the output channel 130. In other embodiments, the vent tube 13 may alternatively be an ellipse circular tube, a square tube, or may be in another shape.
The mounting structure 12 is configured to mount and position the vaporization body 20. The mounting structure 12 is arranged at a middle portion of the liquid storage housing 11, and divides a space inside the liquid storage housing 11 into the liquid storage cavity 110 located at an upper portion and the mounting cavity 111 located at a lower portion. At least one liquid discharging opening 120 is further formed on the mounting structure 12, and the liquid substrate in the liquid storage cavity 110 can flow to the vaporization body 20 through the at least one liquid discharging opening 120.

Each mounting wall 121 also has a third side and a fourth side arranged opposite to each other, and the third side is integrally combined with the vent tube 13. The fourth side extends toward the inner wall surface of a side of the liquid storage housing 11 in a length direction and a gap is formed between the fourth side and the inner wall surface of a side of the liquid storage housing 11 in the length direction, and the gap forms the liquid discharging opening 120. The vent tube 13 may longitudinally extend upward from the upper surfaces of two mounting walls 121 integrally.
Further, the two mounting walls 121 may roughly be arranged in a shape of an inverted V. That is, each mounting wall 121 and an axis of the vent tube 13 form an included angle greater than 90 degrees, so that each mounting wall 121 is inclined downward from a side close to the vent tube 13 in a direction of the liquid discharging opening 120, to facilitate discharging of the liquid substrate, and therefore, the liquid substrate flows downward more smoothly, there is no or little liquid substrate remaining in the liquid storage cavity 110, and utilization of the liquid substrate is improved. In addition, the mounting structure 12 with a V-shaped structure can also cause mounting and positioning of the vaporization body 20 that is mounted to and fits the mounting structure 12 to be more accurate, and can also guide the vaporization body 20 during mounting.
Further, the liquid storage housing 11 may include a first half housing 112 located at the upper portion and a second half housing 113 located at the lower portion. The inner surface of the first half housing 112, the outer surface of the vent tube 13, the upper surface of the mounting structure 12, and the lower surface of the suction nozzle assembly 90 define the liquid storage cavity 110 together. The inner surface of the second half housing 113 and the lower surface of the mounting structure 12 define the mounting cavity 111. A thickness of the first half housing 112 is greater than a thickness of the second half housing 113, so that a cross-sectional dimension of the liquid storage cavity 110 is less than a cross-sectional dimension of the mounting cavity 111, facilitating demolding of the top and the bottom of the liquid storage body 10. Thicknesses of the first half housing 112 and/or the second half housing 113 from the upper end to the lower end thereof may be the same or may be different. Specifically, in this embodiment, the thickness of the first half housing 112 from the upper end to the lower end is the same, that is, the cross-sectional dimension of the liquid storage cavity 110 from the upper end to the lower end is the same; and the thickness of an upper portion of the second half housing 113 is greater than the thickness of a lower portion, so that a cross-sectional dimension of the lower portion of the mounting cavity 111 is greater, to facilitate assembly of the vaporization body 20. The first half housing 112 and the second half housing 113 may be connected in a chamfer transition manner, or may be connected in a step transition manner.
The suction nozzle assembly 90 may include a suction nozzle 91 and a sealing member 92.

In some embodiments, the base 30 may include a main body portion 34 located at a middle portion of the base 30 and a support portion 35 located on two opposite sides of the main body portion 34. The upper surface of the main body portion 34 may recess downward to form a liquid accumulation chamber 340, which can store some condensate, to reduce leaked liquid. The air inlet passage 31 may be formed in the main body portion 34. The upper end surface of the air inlet passage 31 may be higher than the cavity bottom surface of the liquid accumulation chamber 340, to reduce leakage of condensate stored in the liquid accumulation chamber 340 from the air inlet passage 31.
Specifically, the cavity bottom surface of the liquid accumulation chamber 340 may protrude upward to form an air inlet boss 341. The air inlet passage 31 includes at least one air outlet hole 312 extending downward from the upper end surface of the air inlet boss 341. Further,
the at least one air outlet hole 312 includes a plurality of air outlet holes 312. The plurality of air outlet holes 312 include at least one first air outlet small hole 3121 and at least one second air outlet small hole 3122. The first air outlet small hole 3121 and the second air outlet small hole 3122 may have different cross-sectional shapes and/or different cross-sectional areas, or the first air outlet small hole 3121 and the second air outlet small hole 3122 may have the same cross-sectional shape and the same cross-sectional area. In this embodiment, the air inlet boss 341 is located at a middle portion of the liquid accumulation chamber 340, and one of the first air outlet small hole 3121 is located at a middle portion of the air inlet boss 341. A plurality of second air outlet small holes 3122 are provided. The plurality of second air outlet small holes 3122 surround outside the one first air outlet small hole 3121 and are uniformly distributed at intervals in a circumferential direction of the air inlet boss 341. Further, in this embodiment, the first air outlet small hole 3121 and the second air outlet small hole 3122 have different cross-sectional shapes and different cross-sectional areas. Specifically, the cross-sectional shape of the first air outlet small hole 3121 is in a circular shape, the cross-sectional shape of the second air outlet small hole 3122 is in a circular arc shape, and the cross-sectional area of the second air outlet small hole 3122 is greater than the cross-sectional area of the first air outlet small hole 3121. Arrangement manner of the first air outlet small hole 3121 and the second air outlet small hole 3122 can further reduce leaked liquid and reduce noise during inhalation.
It may be understood that in other embodiments, the first air outlet small hole 3121 and the second air outlet small hole 3122 may alternatively be arranged in another manner. For example, a plurality of first air outlet small holes 3121 may alternatively be provided. In another example, the cross-sectional shapes of the first air outlet small hole 3121 and the second air outlet small hole 3122 may be the same or different, and the cross-sectional shape may alternatively be a square shape, a triangular shape, an elliptical shape, or various other shapes. In another example, the cross-sectional area of the second air outlet small hole 3122 may be less than or equal to the cross-sectional area of the first air outlet small hole 3121.
Further, the air inlet passage 31 further includes an air inlet hole 311 communicating with the lower end of the plurality of air outlet holes 312. In this embodiment, the air inlet hole 311, the first air outlet small hole 3121, and the air inlet boss 341 are coaxially arranged. The cross-sectional area of the air inlet hole 311 may be less than the cross-sectional area of the air inlet boss 341 and greater than a total cross-sectional area of the plurality of air outlet holes 312, so that an air inlet amount can be enough on one hand and the air inlet boss 341 can further cover above the air inlet hole 311, to reduce leaked liquid on the other hand.
In some embodiments, at least one air guide groove 32 is further formed on the bottom surface of the base 30 communicating with the air inlet hole 311. In this embodiment, two air guide grooves 32 are provided, one end of each air guide groove 32 communicates with the lower end of the air inlet hole 311, and the other end extends outward in a width direction of the base 30 to penetrate a side of the base 30 in the width direction. After assembly of the vaporizer 100 and the power supply device 200, the bottom surface of the base 30 fits the upper surface of a bracket in the power supply device 200, so that the air guide groove 32 can allow airflow to pass through. According to a fitting structure of the power supply device 200, the air guide groove 32 may be configured for the external air to enter the air inlet passage 31, or may be configured to communicate the air inlet passage 31 with an airflow sensor in the power supply device 200. In other embodiments, the air guide groove 32 may alternatively extend in a non-straight line shape, and/or an end of the air guide groove 32 away from the air inlet hole 311 may not penetrate the side surface of the base 30. In some other embodiments, the bottom surface of the base 30 may not be provided with the air guide groove 32.
Two support portions 35 are symmetrically arranged on two sides of the base 30 in a length direction respectively, configured to support the fixing base 40 and the heating base 60. The upper end surface of the support portion 35 may be higher than the upper end surface of the main body portion 34, so that an interval exists between the bottom surfaces of the fixing base 40 and the heating base 60 and the upper end surface of the main body portion 34, facilitating heat insulation. The upper end surface of the support portion 35 may alternatively recess downward to form at least one injection hole 350, facilitating injection molding of the base 30 and further facilitating heat insulation between the base 30 and the fixing base 40 and the heating base 60.
Further, a sealing ring 38 may further be sleeved between the outer circumferential surface of the base 30 and the inner circumferential surface of the liquid storage housing 11. The sealing ring 38 may be made of an elastic material such as silicon, to improve sealing effect on the liquid storage cavity 110. In this embodiment, the sealing ring 38 is an O-shaped sealing ring and is sleeved on the base 30.
At least one electrode column 37 longitudinally penetrates the base 30, configured to electrically connect the vaporization core 51 with the power supply device 200. In this embodiment, two electrode columns 37 are provided. The two electrode columns 37 are respectively arranged on two opposite sides of the air inlet boss 341. The two electrode columns 37 and the air inlet boss 341 are distributed in the length direction of the base 30, so that an enough gap space can be formed between the two electrode columns 37. Correspondingly, two mounting holes 33 is formed by longitudinally penetrating the base 30, for the two electrode columns 37 to penetrate respectively. Further, the two mounting holes 33 may be located in the liquid accumulation chamber 340, and the upper end surfaces of the two mounting holes 33 are both higher than the cavity wall surface of the liquid accumulation chamber 340, to reduce leaked liquid from the two mounting holes 33.
In some embodiments, the vaporizer 100 may further include a fixing sleeve 15 sleeved outside the liquid storage housing 11 and the bottom portion of the base 30. The fixing sleeve 15 may be fixedly connected to the lower side wall of the liquid storage housing 11 through fastening fitting, to fix the base 30. The bottom surface of the base 30 may further protrude downward to form a protrusion 36. The bottom wall of the fixing sleeve 15 is penetrated to form a through hole 150. The protrusion 36 is arranged in the through hole 150 and is exposed through the through hole 150. The air inlet hole 311, the mounting hole 33, and the air guide groove 32 are all formed on the protrusion 36, to reduce a quantity of holes on the fixing sleeve 15.
Further, in some embodiments, the fixing sleeve 15 may be made of a metal material, and the metal material has smaller deformation of thermal expansion and cold contraction as temperature changes, so that connection and fixing between various parts in the liquid storage housing 11 is more stable and reliable, and the seal performance is better. In addition, the fixing sleeve 15 made of the metal material has a function of magnetic attraction and can be configured for magnetic attraction and fixing between the vaporizer 100 and the power supply device 200. It may be understood that in other embodiments, the fixing sleeve 15 may alternatively be made of a plastic or another material.
In this embodiment, two vaporization assemblies 50 are provided. The two vaporization assemblies 50 are arranged at an interval in the length direction of the liquid storage housing 11 and are arranged rotationally symmetrical along a central axis of the vaporization body 20. A gap between the two vaporization assemblies 50 defines a vaporization cavity 510. Each vaporization assembly 50 includes a vaporization core 51, a first electrode sheet 52, a second electrode sheet 53, and an insulation sleeve 54. The vaporization core 51 includes a liquid absorbing body 511 and a heating element 512 arranged on the liquid absorbing body 511. The liquid absorbing body 511 is configured to absorb the liquid substrate from the liquid storage cavity 110 and guide the liquid substrate to the heating element 512. The heating element 512 is configured to heat and vaporize the liquid substrate absorbed by the liquid absorbing body 511 after power-on. The first electrode sheet 52 and the second electrode sheet 53 are electrically connected to two poles of the heating element 512 respectively, and the two poles of the heating element 512 are further electrically connected to the two electrode columns 37.
Specifically, in this embodiment, the liquid absorbing body 511 is made of porous ceramic, which can absorb the liquid substrate from the liquid storage cavity 110 through infiltration and capillary effect of an internal microporous structure of the porous ceramic. The liquid absorbing body 511 has a liquid absorbing surface 5111 and a heating surface 5112. The liquid absorbing surface 5111 communicates with the liquid storage cavity 110 in a liquid guiding manner, and is configured to absorb the liquid substrate from the liquid storage cavity 110. The heating surface 5112 is the side surface of the liquid absorbing body 511 on which the heating element 512 is arranged. In this embodiment, the liquid absorbing body 511 is in a shape of a rectangular plate and is vertically arranged, whose thickness is relative small. Specifically, the length dimension of the liquid absorbing body 511 is greater than the width dimension, and the width dimension is greater than the thickness dimension. The liquid absorbing surface 5111 and the heating surface 5112 are two surfaces of the liquid absorbing body 511 that are vertically arranged and that are arranged opposite to each other in a thickness direction. The liquid absorbing surface 5111 is arranged facing away from the vaporization cavity 510, and the heating surface 5112 is arranged facing the vaporization cavity 510. It may be understood that in other embodiments, the liquid absorbing body 511 is not limited in a shape of a rectangular plate; and the liquid absorbing surface 5111 may not be arranged opposite to the heating surface 5112. For example, the liquid absorbing surface 5111 may be located on the upper surface of the liquid absorbing body 511.
The heating element 512 may be a heating film, which can be integrally formed on the liquid absorbing body 511 by screen printing, printing, or the like. In other embodiments, the heating element 512 may alternatively be a metal heating sheet or a metal heating wire separately formed. The heating element 512 includes a heating portion 5121 and two electrode portions 5122 respectively arranged at two ends of the heating portion 5121. The two electrode portions 5122 may be respectively arranged at two ends of the heating surface 5112 in a length direction, and may be made of a material with low resistivity, so that the two electrode portions 5122 do not generate heat or generate little heat. The heating portion 5121 is connected between the two electrode portions 5122, and can be arranged in a curved or bent manner, so that the heating portion 5121 has a longer extending path. The heating portion 5121 may be made of a material with high resistivity, and is configured to generate heat after power-on to heat the liquid substrate. In this embodiment, the heating portion 5121 is roughly S-shaped. In other embodiments, the heating portion 5121 may alternatively be in a spiral shape (such as a square spiral shape or an elliptical spiral shape), a polyline shape (such as a square wave shape), or another shape.
The first electrode sheet 52 and the second electrode sheet 53 are both metal sheets, which may be made of a material with low resistivity. The first electrode sheet 52 and the second electrode sheet 53 cover a part of the surface of the vaporization core 51, completing electrical connection and increasing strength of the vaporization core 51 during assembly. The insulation sleeve 54 is sleeved outside the first electrode sheet 52, the second electrode sheet 53, and the vaporization core 51, and may be made of an insulating and high-temperature-resistance material such as silicon. Therefore, the insulation sleeve 54 has a certain buffer to protect the vaporization core 51 during mounting, further increasing integrity of the entire vaporization core 51 and ensuring that the vaporization core 51 is not squeezed and damaged during mounting, thereby implementing assembly of an ultra-thin vaporization core 51. In addition, the insulation sleeve 54 made of an elastic material can further elastically wrap the vaporization core 51 tightly, ensuring reliability of the electrical connection among the first electrode sheet 52, the second electrode sheet 53, and the vaporization core 51. In other embodiments, the insulation sleeve 54 may alternatively be made of other high-temperature-resistance materials such as plastic. Further, the insulation sleeve 54, the first electrode sheet 52, the second electrode sheet 53 can be integrally formed to be combined together. Then the insulation sleeve 54, the first electrode sheet 52, and the second electrode sheet 53 that are integrally formed cover the vaporization core 51, and the first electrode sheet 52 and the second electrode sheet 53 are in contact with the two electrode portions 5122 for conduction respectively, so that assembly of the vaporization assembly 50 is more convenient and the electrical connection among the first electrode sheet 52, the second electrode sheet 53, and the vaporization core 51 is more reliable. In addition, the vaporization core 51 can further be protected from being squeezed and damaged, to ensure integrity of the vaporization core 51.
In this embodiment, the first electrode sheet 52 and the second electrode sheet 53 cover part of the four surfaces of the vaporization core 51. Specifically, the first electrode sheet 52 includes a first electrode connection end 521 configured to be connected to one electrode portion 5122, a first outer connection end 523 configured to be connected to an external power supply, and a first connection portion 522 connecting the first electrode connection end 521 with the first outer connection end 523. The first electrode connection end 521, the first connection portion 522, and the first outer connection end 523 respectively cover part of three surfaces of the vaporization core 51. The second electrode sheet 53 includes a second electrode connection end 531 configured to be connected to the other electrode portion 5122, a second outer connection end 533 configured to be connected to the external power supply, and a second connection portion 532 connecting the second electrode connection end 531 with the second outer connection end 533. It may be understood that in other embodiments, the first electrode sheet 52 may alternatively cover part of two or more surfaces of the vaporization core 51, and/or the first electrode sheet 52 may alternatively cover part of two or more surfaces of the vaporization core 51.
The first electrode connection end 521 and the second electrode connection end 531 respectively cover the two electrode portions 5122, and are in contact with the two electrode portions 5122 for conduction. The area of the first electrode connection end 521 and the area of the second electrode connection end 531 are both greater than the area of the electrode portion 5122, so that the area of the first electrode connection end 521 and the second electrode connection end 531 can fully cover the two electrode portions 5122 to ensure performance of electrical connection.
The first connection portion 522 and the second connection portion 532 are respectively arranged on two opposite surfaces of the vaporization core 51. The first outer connection end 523 and the second outer connection end 533 respectively cover part of the bottom surface of the vaporization core 51, to facilitate contact with the upper ends of the two electrode columns 37 for conduction. In other embodiments, the first outer connection end 523 and the second outer connection end 533 may alternatively be arranged on another same side surface of the vaporization core 51, for example, the front side surface or the rear side surface.
In some other embodiments, the first outer connection end 523 and the second outer connection end 533 may alternatively be located on different side surfaces of the vaporization core 51.
Further, at least one first combination hole 520 and at least one second combination hole 530 may alternatively be formed on the first electrode sheet 52 and the second electrode sheet 53 respectively, so that the first electrode sheet 52, the second electrode sheet 53, and the insulation sleeve 54 can be combined more stably during integral forming. In this embodiment, the first electrode connection end 521 and the second electrode connection end 531 are respectively provided with a first combination hole 520, and the first outer connection end 523 and the second outer connection end 533 are respectively provided with a second combination hole 530.

Further, the vaporization body 20 further includes an electrode connector 70. Two vaporization cores 51 can be connected in parallel or in series by the electrode connector 70. In this embodiment, two electrode connectors 70 are provided, the two electrode connectors 70 horizontally extend and are arranged in parallel at an interval, and the two vaporization cores 51 are connected in parallel by the two electrode connectors 70. Specifically, each electrode connector 70 includes an electrode connection portion 71 and two electrode contacts 72 respectively located on two ends of the electrode connection portion 71. The electrode connection portion 71 is in a rod shape extending horizontally, and the lower end surface of the electrode connection portion 71 is in contact with the electrode column 37 for conduction. The two electrode contacts 72 integrally extend upward from the upper end surfaces of the two ends of the electrode connection portion 71 respectively. The two electrode contacts 72 are respectively in contact with one outer connection end of the first electrode sheet 52 and one outer connection end of the second electrode sheet 53 for conduction. The insulation sleeve 54 is further provided with two electrode holes 541, so that the electrode contact 72 can penetrate the electrode hole 541 to be in contact with the outer connection ends of the first electrode sheet 52 and the second electrode sheet 53 for conduction.
Further, in this embodiment, each electrode column 37 includes a columnar body 371, an extending portion 372 integrally arranged at the upper end of the columnar body 371, and a conduction contact 373 extending upward from the top surface of the extending portion 372. The conduction contact 373 is configured to be in contact with the electrode connection portion 71 for conduction. The columnar body 371 may be in a cylindrical shape and penetrate the mounting hole 33, and in other embodiments, the columnar body 371 may alternatively be in a square columnar shape, or another shape. The extending portion 372 may extend out for a certain length toward a side horizontally from a top portion of the columnar body 371, and the conduction contact 373 is located on the side of the extending portion 372 away from the columnar body 371. The extending portions 372 of the two electrode columns 37 extend in opposite directions, so that the conduction contacts 373 of the two electrode columns 37 can be staggered by a certain distance, to be in contact with the two electrode connection portions 71 arranged at an interval for conduction. A structure of the electrode column 37 can reduce the dimension of the mounting hole 33 on the base 30, and can adapt requirements of a small thickness of the vaporizer 100. It may be understood that in other embodiments, a structure of the electrode column 37 may also be changed adaptively. For example, the columnar bodies 371 of the two electrode columns 37 may also be staggered without arranging the extending portion 372.
A liquid inlet opening 540 communicating the liquid absorbing surface 5111 of the liquid absorbing body 511 with the liquid storage cavity 110 and a vent opening 542 communicating the heating surface 5112 of the liquid absorbing body 511 with the vaporization cavity 510 are formed on the insulation sleeve 54. The liquid substrate in the liquid storage cavity 110 is discharged through the liquid discharging opening 120, and is absorbed by the liquid absorbing surface 5111 of the liquid absorbing body 511 through the liquid inlet opening 540; the liquid substrate absorbed by the liquid absorbing surface 5111 of the liquid absorbing body 511 is guided to the heating surface 5112 through a microporous structure inside the liquid absorbing body 511, and is heated and vaporized on the heating surface 5112 to generate an aerosol; and airflow entering from the air inlet passage 31 flows to the vaporization cavity 510 and brings out the generated aerosol after vaporization through the output channel 130 and the inhalation channel 93 in sequence. Further, the vent opening 542 enables most of the heating portion 5121 to be exposed, so as to fully bring out the generated aerosol after vaporization on one hand and reduce direct contact between the heating portion 5121 with a high temperature and the insulation sleeve 54 to reduce heat transmitted from the heating portion 5121 to the insulation sleeve 54.
In other embodiments, the liquid absorbing body 511 may alternatively be a liquid absorbing body with holes arranged in arrays. That is, liquid absorbing holes arranged in arrays is formed on the liquid absorbing body 511, and through the liquid absorbing holes arranged in arrays, the heating surface 5112 is communicated with the liquid storage cavity 110. In this case, the first electrode sheet 52, the second electrode sheet 53, and the insulation sleeve 54 are limited to not covering the heating portion 5121, to prevent the heating element 512 from dry heating because the first electrode sheet 52, the second electrode sheet 53, and the insulation sleeve 54 cover part of the liquid absorbing holes close to the heating portion 5121.

In some embodiments, a vent channel 64 may further be formed on the heating base 60, the vent channel 64 communicates the liquid storage cavity 110 with the outside and is configured to balance pressure in the liquid storage cavity 110, causing the liquid to flow more fully, to resolve a problem that negative pressure in the liquid storage cavity 110 is excessively large and the liquid cannot flow stably. Specifically, in this embodiment, two vent channels 64 are provided, each vent channel 64 includes a vent groove 641 formed between the limit portion 62 and the insulation sleeve 54 and a vent hole 642 formed in the heating base 60. The vent groove 641 may be formed by recessing the side surface of the limit portion 62 that fits the insulation sleeve 54 inward, and in other embodiments, the vent groove 641 may alternatively be formed by recessing the side surface of the insulation sleeve 54 that fits the limit portion 62 inward. The vent hole 642 may longitudinally penetrate the top wall 65, whose lower end communicates with the vent groove 641. A vent opening 1210 further penetrates the mounting structure 12 corresponding to the vent hole 642, to communicate the vent hole 642 with the liquid storage cavity 110.
In some embodiments, the outer surface of the heating base 60 may be alternatively provided with a communication groove 66 configured to communicate the liquid storage cavities 110 of two sides. Further, the communication groove 66 may be a capillary groove. When the vaporizer 100 is inclined in use, causing liquid substrate in the liquid storage cavity 110 of one side to be reduced, liquid substrate in the liquid storage cavity 110 of the other side is added to the one side through capillary force of the communication groove 66 and the gravity of the liquid substrate, to avoid dry heating of the one side. In this embodiment, the outer surfaces of two sides of the heating base 60 in the width direction are both provided with a plurality of communication grooves 66. Each communication groove 66 horizontally extends, and the plurality of communication grooves 66 are uniformly distributed at intervals vertically.

Airflow from the vent hole 44 can be diverged and guided by the diverging structure 43, to flow to the heating surfaces 5112 of the two vaporization assemblies 50, so that a release amount of the vaporized aerosol is improved and inhalation is more fully. In this embodiment, the diverging structure 43 is integrally formed with the embedding portion 42 and the base portion 41.
