FIG. 1 and FIG. 2 show an electronic vaporization device 1 according to some embodiments of the present invention. The electronic vaporization device 1 includes a vaporizer 100 and a power supply device 200 connected to the vaporizer 100 in match. The vaporizer 100 may be detachably inserted longitudinally into the upper portion of the power supply device 200. The power supply device 200 is configured to supply power to the vaporizer 100 and can control operations such as turning on and turning off the entire electronic vaporization device 1. The vaporizer 100 is configured to accommodate a liquid substrate, and heat and vaporize the liquid substrate after the vaporizer 100 is powered on to generate an aerosol. It may be understood that in other embodiments, the vaporizer 100 and the power supply device 200 may also be connected together in a non-detachable manner.
As shown in FIG. 3 to FIG. 5 , the vaporizer 100 may include a liquid storage body 10, a vaporization body 20, and a suction nozzle member 90. The vaporization body 20 and the suction nozzle member 90 are respectively arranged at two ends of the liquid storage body 10. A liquid storage cavity 110 for storing a liquid substrate, an output channel 130 for transporting an aerosol, and a mounting cavity 111 for accommodating the vaporization body 20 are formed in the liquid storage body 10. The suction nozzle member 90 is longitudinally arranged at the upper end of the liquid storage body 10 and seals the upper end of the liquid storage cavity 110, and an inhalation channel 93 that is in communication with the output channel 130 is formed inside the suction nozzle member 90. The vaporization body 20 is accommodated at the lower end of the liquid storage body 10. The vaporization body 20 can adsorb the liquid substrate from the liquid storage cavity 110, and heat and vaporize the adsorbed liquid substrate after the vaporization body 20 is powered on to generate an aerosol. The aerosol generated after vaporization is then sequentially output to the outside through the output channel 130 and the inhalation channel 93.
Specifically, the liquid storage body 10 may include a liquid storage shell 11, a ventilation pipe 13, and a mounting structure 12. The liquid storage shell 11 is in a cylindrical shape with two ends open, and the cross section thereof is roughly in the shape of a runway. In other embodiments, the cross-sectional shape of the liquid storage shell 11 may also be elliptical, circular, rectangular, or other shapes.
The ventilation pipe 13 is in a circular tubular shape. The ventilation pipe 13 is longitudinally arranged in the liquid storage shell 11 and may be coaxial with the liquid storage shell 11. The inner wall surface of the ventilation pipe 13 defines the output channel 130. In other embodiments, the ventilation pipe 13 may also be in an elliptical tubular shape, a square tubular shape, or other shapes.
The mounting structure 12 is configured to mount and position the vaporization body 20. The mounting structure 12 is located in the middle of the liquid storage shell 11, and separates the space inside the liquid storage shell 11 into a liquid storage cavity 110 located at an upper portion and a mounting cavity 111 located at a lower portion. At least one liquid downward port 120 is also 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 downward port 120.
In this embodiment, the liquid storage shell 11, the ventilation pipe 13, and the mounting structure 12 are integrally formed, for example, may be integrally formed by injection molding. The mounting structure 12 includes two mounting walls 121, and each mounting wall 121 forms a liquid downward port 120. Specifically, each mounting wall 121 is provided with a first side and a second side that are arranged opposite to each other, and the surfaces of the first side and the second side are integrated respectively with the inner wall surfaces of the two sides of the liquid storage shell 11 along the width direction. Each mounting wall 121 is also provided with a third side and a fourth side that are arranged opposite to each other, and the third side is integrated with the ventilation pipe 13. The fourth side extends towards the inner wall surface of the side of the liquid storage shell 11 along the length direction, and forms a gap with the inner wall surface of the side of the liquid storage shell 11 along the length direction, and the gap forms a liquid downward port 120. The ventilation pipe 13 may extend longitudinally from the upper surfaces of two mounting walls 121.
Further, the two mounting walls 121 may be roughly arranged in an inverted V-shape, that is, an angle greater than 90 degrees is formed between each mounting wall 121 and the axis of the ventilation pipe 13, so that each mounting wall 121 tilts downwards from the side that is close to the ventilation pipe 13 toward the liquid downward port 120, which is more conducive to the downflow of the liquid substrate, making the downflow of the liquid substrate smoother. There is no or very little residual liquid substrate in the liquid storage cavity 110, and the utilization rate of the liquid substrate is higher. In addition, the mounting structure 12 in a V-shaped structure may also make the mounting and positioning of the vaporization body 20 that matches the mounting structure 12 more accurate, and may also play a guiding role during the mounting of the vaporization body 20.
Further, the liquid storage shell 11 may include a first half shell 112 located at the upper portion and a second half shell 113 located at the lower portion. The inner surface of the first half shell 112, the outer surface of the ventilation pipe 13, the upper surface of the mounting structure 12, and the lower surface of the suction nozzle member 90 jointly define the liquid storage cavity 110. The inner surface of the second half shell 113 and the lower surface of the mounting structure 12 define the mounting cavity 111. The thickness of the first half shell 112 is greater than the thickness of the second half shell 113, so that the cross-sectional size of the liquid storage cavity 110 is less than the cross-sectional size of the mounting cavity 111, which is conducive to the upper and lower demolding of the liquid storage body 10. The thickness of the first half shell 112 and/or the second half shell 113 from the upper end to the lower end may be consistent or inconsistent. Specifically, in this embodiment, the thickness of the first half shell 112 from the upper end to the lower end is consistent, that is, the cross-sectional size of the liquid storage cavity 110 from the upper end to the lower end is the same; and the thickness of the upper portion of the second half shell 113 is greater than the thickness of the lower portion, making the cross-sectional size of the lower portion of the mounting cavity 111 larger, which facilitates the assembly of the vaporization body 20. The first half shell 112 and the second half shell 113 may be connected through chamfered transition or stepped transition.
The suction nozzle member 90 may include a suction nozzle 91 and a sealing component 92 that are mutually matched. The sealing component 92 may be made of elastic materials such as silicone, and the suction nozzle 91 may be made of hard materials such as plastic. The sealing component 92 may be embedded in the lower portion of the suction nozzle 91 and may be connected and fixed with the suction nozzle 91 through a buckle fit. The sealing component 92 is at least partially embedded in the opening of the upper end of the liquid storage shell 11, and configured to seal the upper end of the liquid storage cavity 110. The sealing component 92 may also form an insertion hole 920 longitudinally inside, and the upper end of the ventilation pipe 13 may be sealed and embedded in the insertion hole 920.
The suction nozzle 91 may be sleeved outside the upper end of the liquid storage shell 11 and may be connected and fixed with the liquid storage shell 11 through a buckle fit. The lower end surface of the suction nozzle 91 extends longitudinally upwards to form an air outlet channel 911 that is in communication with the insertion hole 920, and the upper end surface of the suction nozzle 91 is recessed downwards to form an inhalation port 912 that is in communication with the air outlet channel 911. The insertion hole 920, the air outlet channel 911, and the inhalation port 912 are sequentially in communication from bottom to top to form an inhalation channel 93. Further, in this embodiment, there are two inhalation ports 912, and the two inhalation ports 912 may be arranged along the length direction of the suction nozzle 91. In other embodiments, the quantity of inhalation ports 912 may also be one or more.
As shown in FIG. 3 and FIG. 4 , and FIG. 6 to FIG. 8 , the vaporization body 20 includes a base 30 and at least one vaporization member 50 arranged above the base 30. The base 30 is embedded in the lower end opening of the liquid storage shell 11 to block the lower end opening of the liquid storage shell 11. Each vaporization member 50 includes a vaporization core 51, and the vaporization core 51 can extract a liquid substrate from the liquid storage cavity 110 and heat and vaporize the liquid substrate. The vaporizer 100 is mounted on the power supply device 200 through the base 30, and an air inlet 31 is also formed on the base 30 for external air to enter. Further, the vaporization body 20 also includes a fixing base 40 and a heating base 60 that are arranged above the base 30, and is configured to support and fix at least one vaporization member 50.
In some embodiments, the base 30 may include a body portion 34 located in the middle of the base 30 and supporting portions 35 located on opposite sides of the body portion 34. The upper surface of the body portion 34 may be recessed downwards to form a liquid storage cavity 340, which may store a certain amount of condensate and reduce leakage. The air inlet 31 may be formed in the body portion 34, and the upper end surface of the air inlet 31 may be higher than the bottom surface of the liquid storage cavity 340 to reduce the leakage of condensate stored in the liquid storage cavity 340 from the air inlet 31.
Specifically, the bottom surface of the liquid storage cavity 340 may protrude upwards to form an air inlet boss 341, and the air inlet 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, and the plurality of air outlet holes 312 include at least one first small air outlet hole 3121 and at least one second small air outlet hole 3122. The first small air outlet hole 3121 and the second small air outlet hole 3122 may have different cross-sectional shapes and/or cross-sectional areas, or the first small air outlet hole 3121 and the second small air outlet hole 3122 may have the same cross-sectional shape and cross-sectional area. In this embodiment, the air inlet boss 341 is located in the middle of the liquid storage cavity 340, and there is one first small air outlet hole 3121 located in the middle of the air inlet boss 341. There are a plurality of second small air outlet holes 3122, and the plurality of second small air outlet holes 3122 surround outside the first small air outlet hole 3121 and are evenly spaced along the circumferential direction of the air inlet boss 341. Further, in this embodiment, the first small air outlet hole 3121 and the second small air outlet holes 3122 have different cross-sectional shapes and different cross-sectional areas. Specifically, the cross-sectional shape of the first small air outlet hole 3121 is circular, and the cross-sectional shape of the second small air outlet hole 3122 is circular arc, and the cross-sectional area of the second small air outlet hole 3122 is greater than the cross-sectional area of the first small air outlet hole 3121. The arrangement of the first small air outlet hole 3121 and the second small air outlet hole 3122 is conducive to further reducing liquid leakage and reducing noise during inhalation.
It may be understood that in other embodiments, the first small air outlet hole 3121 and the second small air outlet holes 3122 may also be arranged in other ways, for example, there are a plurality of first small air outlet holes 3121. For another example, the cross-sectional shapes of the first small air outlet hole 3121 and the second small air outlet hole 3122 may be the same or different, and the cross-sectional shapes may also be square, triangular, elliptical, and other various shapes. For another example, the cross-sectional area of the second small air outlet hole 3122 may also be less than or equal to the cross-sectional area of the first small air outlet hole 3121.
Further, the air inlet 31 also includes an air inlet hole 311 connected to the lower end of the plurality of air outlet holes 312. In this embodiment, the air inlet hole 311, the first small air outlet hole 3121, and the air inlet boss 341 are all 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 larger than the total cross-sectional area of the plurality of air outlet holes 312, so that it can ensure sufficient air intake. In addition, it can also enable the air inlet boss 341 to cover the upper part of the air inlet hole 311, which is conducive to reducing liquid leakage.
In some embodiments, the bottom surface of the base 30 also forms at least one air guide groove 32 that is in communication with the air inlet hole 311. In this embodiment, there are two air guide grooves 32, one end of each air guide groove 32 is in communication with the lower end of the air inlet hole 311, and the other end extends outward along the width direction of the base 30 to one side that runs through the width direction of the base 30. After the vaporizer 100 is assembled with the power supply device 200, the bottom surface of the base 30 matches the upper surface of the bracket inside the power supply device 200, so that the air guide groove 32 allows airflow to pass through. According to the matching structure of the power supply device 200, the air guide groove 32 may be configured to allow external air to enter the air inlet 31, and can also be configured to communicate the air inlet 31 and an airflow sensor inside the power supply device 200. In other embodiments, the air guide groove 32 may also extend in a non-linear shape, and/or the end of the air guide groove 32 away from the air inlet hole 311 may not run through 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 supporting portions 35 are symmetrically arranged respectively on two sides of the length direction of the base 30 to support the fixing base 40 and the heating base 60. The upper end surface of the supporting portion 35 may be higher than the upper end surface of the body portion 34, so that there is a gap between the bottom surfaces of the fixing base 40 and the heating base 60 and the upper end surface of the body portion 34, which is conducive to heat insulation. The upper end surface of the supporting portion 35 may also be recessed downwards to form at least one injection hole 350, which is conducive to the injection molding of the base 30 and the insulation between the base 30, the fixing base 40, and the heating base 60.
Further, a sealing ring 38 may also be sleeved between the outer surface of the base 30 and the inner surface of the liquid storage shell 11. The sealing ring 38 may be made of elastic materials such as silicone, which is conducive to improving the sealing effect on the liquid storage cavity 110. In this embodiment, the sealing ring 38 is in a shape of O and is sleeved on the base 30.
At least one electrode column 37 may be longitudinally passed through on the base 30 and is configured to electrically connect the vaporization core 51 with the power supply device 200. In this embodiment, there are two electrode columns 37, the two electrode columns 37 are respectively arranged on two opposite sides of the air inlet boss 341, and the two electrode columns 37 and the air inlet boss 341 are arranged along the length direction of the base 30, so that there is sufficient spacing space between the two electrode columns 37. Correspondingly, two mounting holes 33 run through the base 30 longitudinally, which are respectively used for the two electrode columns 37 to run through. Further, the two mounting holes 33 may be located inside the liquid storage cavity 340, and the upper end surfaces of the two mounting holes 33 are higher than the cavity wall surface of the liquid storage cavity 340 to reduce leakage from the two mounting holes 33.
In some embodiments, the vaporizer 100 may also include a fixing sleeve 15 sleeved on the liquid storage shell 11 and outside the bottom portion of the base 30. The fixing sleeve 15 may be fixedly connected with the lower end sidewall of the liquid storage shell 11 through a buckle fit, thereby fixing the base 30. The bottom surface of the base 30 may also protrude downwards to form a protrusion 36, and a through hole 150 runs through the bottom wall of the fixing sleeve 15. The protrusion 36 is arranged in the through hole 150 and 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, which can reduce the quantity of openings 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 shell 11 is more stable and reliable, and the sealing performance is better. In addition, the fixing sleeve 15 made of the metal material also has a magnetic attraction function, which can be used for magnetic attraction fixation between the vaporizer 100 and the power supply device 200. It may be understood that in other embodiments, the fixing sleeve 15 may also be made of plastic or other materials.
In this embodiment, there are two vaporization members 50, the two vaporization members 50 are spaced along the length direction of the liquid storage shell 11 and symmetrically rotated along the central axis of the vaporization body 20. The spacing between the two vaporization members 50 defines a vaporization cavity 510. Each vaporization member 50 includes a vaporization core 51, a first electrode plate 52, a second electrode plate 53, and an insulating sleeve 54. The vaporization core 51 includes a liquid absorbing body 511 and a heating body 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 transmit the liquid substrate to the heating body 512. The heating body 512 is configured to heat and vaporize the liquid substrate adsorbed by the liquid absorbing body 511 after being powered on. The first electrode plate 52 and the second electrode plate 53 are respectively electrically connected with two poles of the heating body 512, so that the two poles of the heating body 512 is electrically connected with the two electrode columns 37.
Specifically, in this embodiment, the liquid absorbing body 511 is a porous ceramic that can absorb the liquid substrate from the liquid storage cavity 110 through the infiltration and capillary effect of the internal microporous structure thereof. The liquid absorbing body 511 has a liquid absorbing surface 5111 and a heating surface 5112. The liquid absorbing body 5111 is in communication with the liquid storage cavity 110, and is configured to absorb the liquid substrate from the liquid storage cavity 110. The heating surface 5112 is provided with a side surface of the heating body 512 for the liquid absorbing body 511. In this embodiment, the liquid absorbing body 511 is in the shape of a rectangular plate arranged vertically, and has a relatively thin thickness. Specifically, the length size of the liquid absorbing body 511 is greater than the width size of the liquid absorbing body 511, and the width size of the liquid absorbing body 511 is greater than the thickness size of the liquid absorbing body 511. The liquid absorbing surface 5111 and the heating surface 5112 are two vertically arranged surfaces that are opposite to each other along the thickness direction of the liquid absorbing body 511. The liquid absorbing surface 5111 faces away from the vaporization cavity 510, and the heating surface 5112 faces the vaporization cavity 510. It may be understood that in other embodiments, the liquid absorbing body 511 is not limited to being in the 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 also be located on the upper surface of the liquid absorbing body 511.
The heating body 512 may be a heating film, and may be integrally formed on the liquid absorbing body 511 through screen printing or printing. In other embodiments, the heating body 512 may also be a separately formed metal heating plate or metal heating wire. The heating body 512 includes a heating portion 5121 and two electrode portions 5122 respectively arranged at two ends of the heating portion 5121. Two electrode portions 5122 may be respectively arranged at two ends of the heating surface 5112 along the length direction, which may be made of low resistivity materials to ensure 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 may be bent to provide a longer extension path for the heating portion 5121. The heating portion 5121 may be made of high resistivity materials, and is configured to generate heat after being powered on to heat the liquid substrate. In this embodiment, the heating portion 5121 is roughly in a shape of S. In other embodiments, the heating portion 5121 may also be in other shapes such as a spiral shape (such as a square spiral shape or an elliptical spiral shape), a broken line shape (such as a square wave shape), and the like.
The first electrode plate 52 and the second electrode plate 53 are both metal plates, and may be made of low resistivity materials. The first electrode plate 52 and the second electrode plate 53 cover a portion of the surface of the vaporization core 51, which not only completes the electrical connection, but also increases the strength during the assembly process of the vaporization core 51. The insulating sleeve 54 is sleeved outside the first electrode plate 52, the second electrode plate 53, and the vaporization core 51, and may be made of insulating elastic and high-temperature resistant materials such as silicone, so that the insulating sleeve 54 may provide a certain buffer protection for the vaporization core 51 during mounting, which further increases the integrity of the vaporization core 51, ensures that the vaporization core 51 is not crushed during mounting, and enables the assembly of the ultra-thin vaporization core 51. In addition, the insulating sleeve 54 made of elastic materials may also elastically wrap the vaporization core 51, which ensures the reliability of the electrical connection between the first electrode plate 52, the second electrode plate 53, and the vaporization core 51. In other embodiments, the insulating sleeve 54 may also be made of other high-temperature resistant materials such as plastic. Further, the insulating sleeve 54, the first electrode plate 52, and the second electrode plate 53 may be integrated through one-time molding and other methods.

The first electrode plate 52 and the second electrode plate 53 are respectively in contact with the two electrode portions 5122 for conduction, making the assembly of the vaporization member 50 more convenient, and the electrical connection between the first electrode plate 52, the second electrode plate 53, and the vaporization core 51 is more reliable. In addition, the possibility of the vaporization core 51 not being crushed during mounting may further be reduced, which ensures the integrity of the vaporization core 51.

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 may fully cover the two electrode portions 5122, which ensures the electrical connection performance.
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 external connection end 523 and the second external connection end 533 respectively cover a portion of the surface of the bottom surface of the vaporization core 51, which is convenient to be in contact with the upper ends of two electrode columns 37 for conduction. In other embodiments, the first external connection end 523 and the second external connection end 533 may also be arranged on the other same side surface of the vaporization core 51, such as the front side surface or the rear side surface.
In some other embodiments, the first external connection end 523 and the second external connection end 533 may also be located on different side surfaces of the vaporization core 51.
Further, at least one first binding hole 520 and at least one second binding hole 530 may also be formed on the first electrode plate 52 and the second electrode plate 53 respectively, which can make the bonding between the first electrode plate 52, the second electrode plate 53, and the insulating sleeve 54 more firm when integrated.

Further, the vaporization body 20 further includes an electrode connection component 70, and the two vaporization cores 51 may be connected in parallel or in series through the electrode connection component 70. In this embodiment, there are two electrode connection components 70, and the two electrode connection components 70 extend horizontally and are arranged spaced. The two vaporization cores 51 are connected in parallel through the two electrode connection components 70. Specifically, each electrode connection component 70 includes an electrode connection portion 71 and two electrode contact points 72 located at two ends of the electrode connection portion 71. The electrode connection portion 71 is in a horizontally extending rod shape, and the lower end surface of the electrode connection portion 71 is in contact with the electrode column 37 for conduction. The two electrode contact points 72 extend upward from the upper end surfaces of two ends of the electrode connection portion 71, and the two electrode contact points 72 are respectively in contact with an external connection end of the first electrode plate 52 and an external connection end of the second electrode plate 53 for conduction. Two electrode holes 541 are also formed on the insulating sleeve 54 to enable the electrode contact point 72 to pass through the electrode holes 541 and be in contact with the external connection ends of the first electrode plate 52 and the second electrode plate 53 for conduction.
Further, in this embodiment, each electrode column 37 includes a column body 371, an extending portion 372 integrally arranged at the upper end of the column body 371, and a conductive contact point 373 extending upward from the top surface of the extending portion 372.

The extending portion 372 may extend a certain length transversally from the top portion of the column body 371 to one side, and the conductive contact point 373 is located on the side of the extending portion 372 that is away from the column body 371. The extending portions 372 of the two electrode columns 37 extend in opposite directions, so that the conductive contact points 373 of the two electrode columns 37 may be staggered for a certain distance, so as to be in contact with the two electrode connection portions 71 arranged spaced for conduction. The structure of the electrode column 37 can reduce the size of the mounting hole 33 on the base 30, and can adapt to the requirement for a thinner thickness of the vaporizer 100. It may be understood that in other embodiments, the structure of the electrode column 37 may also be adapted, for example, the column bodies 371 of the two electrode columns 37 may also be arranged staggered, so that there is no need to arrange an extending portion 372.
The insulating sleeve 54 is also formed with a liquid inlet port 540 that communicates the liquid absorbing surface 5111 of the liquid absorbing body 511 with the liquid storage cavity 110, and a ventilation port 542 that communicates the heating surface 5112 of the liquid absorbing body 511 with the vaporization cavity 510. The liquid substrate in the liquid storage cavity 110 is downflowed through the liquid downward port 120, and further adsorbed by the liquid absorbing surface 5111 of the liquid absorbing body 511 through the liquid inlet port 540; the liquid substrate adsorbed by the liquid absorbing surface 5111 of the liquid absorbing body 511 is transmitted to the heating surface 5112 through the porous microporous structure inside the liquid absorbing body 511, and is heated and vaporized on the heating surface 5112 to generate an aerosol; and the airflow entering from the air inlet 31 flows into the vaporization cavity 510, and the generated aerosol after vaporization is sequentially carried out through the output channel 130 and the inhalation channel 93. Further, the ventilation port 542 may expose most of the heating portion 5121, which is beneficial for fully carrying out the aerosol generated after vaporization. In addition, the direct contact between the high-temperature heating portion 5121 and the insulating sleeve 54 may be reduced, and the heat transferred by the heating portion 5121 to the insulating sleeve 54 is reduced.
In other embodiments, the liquid absorbing body 511 may also be an array hole type liquid absorbing body, that is, an array of liquid absorbing holes are formed on the liquid absorbing body 511, and the heating surface 5112 is in communication with the liquid storage cavity 110 through the liquid absorbing holes arranged in array. In this case, the first electrode plate 52, the second electrode plate 53, and the insulating sleeve 54 are limited to not covering the heating portion 5121, to avoid the first electrode plate 52, the second electrode plate 53, and the insulating sleeve 54 covering some of the liquid absorbing holes that are close to the heating portion 5121, and causing the heating body 512 to dry out.

In some embodiments, the heating base 60 also forms a vent channel 64, and the vent channel 64 communicates the liquid storage cavity 110 with the outside for balancing the pressure inside the liquid storage cavity 110, so that the downflow is more sufficient and the problem of unstable downflow due to excessive negative pressure inside the liquid storage cavity 110 is solved. Specifically, in this embodiment, there are two vent channels 64, and each vent channel 64 includes a vent groove channel 641 formed between the limiting portion 62 and the insulating sleeve 54, and a vent hole 642 formed inside the heating base 60. The vent groove channel 641 may be formed by a surface on a side on which the limiting portion 62 matches the insulating sleeve 54 being recessed inwards.

Further, the communication groove 66 may be a fine groove. When the vaporizer 100 is tilted and used, resulting in a small amount of liquid substrate on one side of the liquid storage cavity 110, the liquid substrate in the other side of the liquid storage cavity 110 may be replenished through the capillary action of the communication groove 66 and the gravity action of the liquid substrate to avoid dry burning on one side. In this embodiment, the outer surfaces on two sides of the heating base 60 along the width direction are provided with a plurality of communication grooves 66. Each communication groove 66 extends horizontally, and the plurality of communication grooves 66 are evenly arranged spaced vertically.
