Description

CROSS-REFERENCE TO PRIOR APPLICATION

Priority is claimed to Chinese patent application Ser. No. 20/231,0073512.X, filed on Jan. 13, 2023, the entire disclosure of which is hereby incorporated by reference herein.

FIELD

The present invention relates to the field of vaporization technologies, and more specifically, to an electronic vaporization device and a vaporizer thereof.

BACKGROUND

An electronic vaporization device is configured to heat and vaporize a vaporizable liquid substrate to generate inhalable aerosols. The electronic vaporization device generally includes a vaporizer and a power supply device. The vaporizer is mainly configured to store a liquid substrate and vaporize the liquid substrate after being energized. The power supply device is mainly configured to recognize an inhalation action, control power supply, and supply power to the vaporizer. An airflow sensor is usually disposed in the power supply device, and is configured to recognize an inhalation action, to determine whether to turn on the electronic vaporization device.
An existing vaporizer usually uses a single-airway structure. In an inhalation process, a main airway is blocked due to the generation of a condensate in the single-airway vaporizer. After the main airway is blocked, the airflow sensor perceives no change in airflow, and as a result the electronic vaporization device can no longer be turned on.

SUMMARY

In an embodiment, the present invention provides a vaporizer, comprising: a shell; an outer tube disposed in the shell; and an inner tube disposed in the outer tube, wherein an inhalation opening is formed at an end of the shell, wherein a main airway in communication with the inhalation opening is formed inside the inner tube, and wherein an auxiliary airway in communication with the inhalation opening is formed between the outer tube and the inner tube.

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 fittingly connected to the vaporizer 100. The power supply device 200 generally includes a battery that supplies power to the vaporizer 100, an airflow sensor configured to detect a change in airflow, and a control circuit configured to control heat generation of the vaporizer 100. The vaporizer 100 is configured to hold a liquid substrate and is configured to heat and vaporize the liquid substrate after being energized to generate aerosols. In some embodiments, the vaporizer 100 and the power supply device 200 may both be approximately in a shape of a cylinder, and may be arranged to provide an axial mechanical connection and an electrical connection together with each other. Further, the vaporizer 100 and the power supply device 200 may be connected together in a detachable manner such as a magnetic attraction connection, a threaded connection, or a buckle connection. It may be understood that, in other embodiments, the vaporizer 100 and the power supply device 200 may be alternatively connected together in a non-detachable manner. In addition, shapes of the cross sections of the vaporizer 100 and/or the power supply device 200 are not limited to a circular shape, and may be other shapes such as an elliptical shape, a racetrack shape, or a rectangular shape.
As shown in FIG. 3 and FIG. 4 , in some embodiments, the vaporizer 100 may include a shell 10, an outer tube 20 disposed in the shell 10, an inner tube 30 disposed in the outer tube 20, and a vaporization assembly 40 disposed in the shell 10. A liquid storage cavity 110 configured to store a liquid substrate is formed in the shell 10. An inhalation opening 123 is formed at an end of the shell 10. A main airway 33 in communication with the inhalation opening 123 is formed inside the inner tube 30. An auxiliary airway 23 in communication with the inhalation opening 123 is formed between the inner tube 30 and the outer tube 20. The vaporization assembly 40 is in liquid-guide communication with the liquid storage cavity 110 and is in gas-guide communication with the main airway 33. The vaporization assembly 40 can heat and vaporize the liquid substrate from the liquid storage cavity 110 after being energized to generate aerosols. The aerosols are then outputted through the main airway 33 to the inhalation opening 123 for a user to smoke or inhale. In the present invention, the independent auxiliary airway 23 is added, so that when a blockage occurs in the main airway 33, during inhalation by a user at the inhalation opening 123, airflow may bypass the main airway 33 and turn on an airflow sensor through the auxiliary airway 23. After the vaporization assembly 40 is energized to generate heat, a viscous liquid substrate around the vaporization assembly 40 and inside the main airway 33 is heated and diluted, to clear the blockage in the main airway 33, so that it is ensured that the vaporizer 100 can normally perform inhalation work.
In some embodiments, an air inlet channel 130 that communicates the main airway 33 and the auxiliary airway 23 with the outside may be further formed in the shell 10. Lower ends of the main airway 33 and the auxiliary airway 23 are both in communication with the air inlet channel 130, and upper ends are both in communication with the inhalation opening 123. During inhalation, external air separately enters the main airway 33 and the auxiliary airway 23 through the air inlet channel 130, and then flows out through the inhalation opening 123.
Specifically, the shell 10 may include a liquid storage shell 11, a suction nozzle 12 disposed at an upper end of the liquid storage shell 11, and a base 13 disposed at a lower end of the liquid storage shell 11. The liquid storage shell 11 may be in a circular tube shape with openings at two ends. The liquid storage cavity 110 is formed in the liquid storage shell 11. A lower end of the suction nozzle 12 may be inserted in an opening at the upper end of the liquid storage shell 11, to block an upper end of the liquid storage cavity 110 in a sealed manner. In some embodiments, the suction nozzle 12 may be connected to the upper end of the liquid storage shell 11 in a detachable manner, so that a liquid substrate may be added to the liquid storage cavity 110 in a manner of detaching the suction nozzle 12 from the liquid storage shell 11, thereby extending service life of the vaporizer 100. In other embodiments, the suction nozzle 12 and the liquid storage shell 11 may be connected together in a non-detachable manner, or the suction nozzle 12 and the liquid storage shell 11 may be of an integral structure.
An air outlet hole 120 is formed longitudinally penetrating the suction nozzle 12, and the inhalation opening 123 is formed at an outlet at an upper end of the air outlet hole 120. The air outlet hole 120 may include a first hole section 121 and a second hole section 122 that are in sequential communication from bottom to top in an axial direction. Upper ends of the outer tube 20 and the inner tube 30 may be accommodated in the first hole section 121. A cross-sectional area of the first hole section 121 is larger than a cross-sectional area of the second hole section 122, to form a step surface 1211 at a connection between the first hole section 121 and the second hole section 122.
The outer tube 20 and the inner tube 30 may be both in a circular tube shape, and may be coaxially disposed with the liquid storage shell 11. It may be understood that, in other embodiments, the liquid storage shell 11 and/or the outer tube 20 and/or the inner tube 30 are not limited to a circular tube shape, and may be in another shape such as an elliptical tube shape or a square tube shape. The outer tube 20 is longitudinally disposed in the liquid storage shell 11, and the annular liquid storage cavity 110 is formed between an outer wall surface of the outer tube 20 and an inner wall surface of the liquid storage shell 11. The auxiliary airway 23 is formed between an inner wall surface of the outer tube 20 and an outer wall surface of the inner tube 30. The vaporization assembly 40 may be accommodated in the inner tube 30 and coaxially disposed with the inner tube 30. At least one first liquid inlet 210 and at least one second liquid inlet 3120 are respectively correspondingly opened in the outer tube 20 and the inner tube 30, to communicate the liquid storage cavity 110 with the vaporization assembly 40.
In some embodiments, the outer tube 20 may include a first outer tube section 21 and a second outer tube section 22 that are sequentially connected from bottom to top in an axial direction. An outer diameter and an inner diameter of the first outer tube section 21 are respectively larger than an outer diameter and an inner diameter of the second outer tube section 22. The inner tube 30 may include a first inner tube section 31 and a second inner tube section 32 that are sequentially connected from bottom to top in an axial direction. An outer diameter and an inner diameter of the first inner tube section 31 are respectively larger than an outer diameter and an inner diameter of the second inner tube section 32. The first inner tube section 31 is disposed in the first outer tube section 21, the second inner tube section 32 is disposed in the second outer tube section 22, and the vaporization assembly 40 may be accommodated in the first inner tube section 31. The outer tube 20 and the inner tube 30 use a step structure, have larger sizes at lower ends to ensure that there is enough space inside to accommodate the vaporization assembly 40, and have smaller sizes at upper ends to ensure that the liquid storage cavity 110 formed between the outer tube 20 and the liquid storage shell 11 has larger liquid storage space.
The outer diameter and the second inner tube section 32 may be smaller than the inner diameter of the second outer tube section 22, so that an annular airflow channel 320 is formed between an outer wall surface of the second inner tube section 32 and an inner wall surface of the second outer tube section 22. The annular airflow channel 320 may be configured to form a part of the auxiliary airway 23. At least one air guide groove 310 may be recessed to be formed in an outer wall surface of the first inner tube section 31. An upper end of the at least one air guide groove 310 is in communication with a lower end of the annular airflow channel 320, to implement communication to form the auxiliary airway 23. In this embodiment, there are two air guide grooves 310. The two air guide grooves 310 are symmetrically disposed on two sides of the first inner tube section 31 in a radial direction, and each air guide groove 310 is a linear channel that extends upward from a lower end of the first inner tube section 31 to an upper end of the first inner tube section in a longitudinal direction. It may be understood that, in other embodiments, there may be one or more than two air guide grooves 310, and the air guide groove 310 may be a nonlinear channel.
It may be understood that, in other embodiments, the auxiliary airway 23 is not limited to the foregoing formed structure. For example, the air guide groove 310 may keep extending upward from the lower end of the first inner tube section 31 to reach an upper end of the second inner tube section 32. In this case, an outer diameter of the second inner tube section 32 may be equal to the inner diameter of the second outer tube section 22. In another example, the air guide groove 310 may be formed in the inner wall surface of the outer tube 20, or may be formed in both the inner wall surface of the outer tube 20 and the outer wall surface of the inner tube 30.
At least one pressure relief hole 220 is opened in the outer tube 20. The at least one pressure relief hole 220 communicates the liquid storage cavity 110 with the outside, and is configured to balance pressure inside the liquid storage cavity 110, to ensure smooth liquid flowing. A position of the pressure relief hole 220 may be higher than an upper end surface of the liquid storage cavity 110, so that leakage of the liquid substrate in the liquid storage cavity 110 through the pressure relief hole 220 can be reduced. In this embodiment, the pressure relief hole 220 is opened in the second outer tube section 22 and is in communication with the annular airflow channel 320, and a plurality of pressure relief holes 220 may be provided and may be arranged at uniform intervals in a circumferential direction of the second outer tube section 22.
Upper ends of the second inner tube section 32 and the second outer tube section 22 may extend into the first hole section 121. An outer wall surface of the second outer tube section 22 fits a hole wall surface of the first hole section 121 in a sealed manner, to avoid leakage of the liquid substrate in the liquid storage cavity 110. A gap is formed between an upper end surface of the second inner tube section 32 and the step surface 1211, to form a communication channel 1210 that communicates the auxiliary airway 23 with the second hole section 122. It may be understood that, in other embodiments, communication between the auxiliary airway 23 and the second hole section 122 may be implemented in another manner. For example, a communication opening that communicates the auxiliary airway 23 with the second hole section 122 may be opened in the upper end of the second inner tube section 32 or at a position near the upper end. In another example, the communication between the auxiliary airway 23 and the second hole section 122 may be implemented by setting an outer diameter of the upper end of the second inner tube section 32 to be smaller than a hole diameter of the second hole section 122.
Further, in some embodiments, the first inner tube section 31 may include a first portion 311 and a second portion 312 connected to an upper end of the first portion 311. The first portion 311 and the second portion 312 may have a same inner diameter. An outer diameter of the second portion 312 is the same as the inner diameter of the first outer tube section 21, to implement fixing of the inner tube 30 in the outer tube 20. The vaporization assembly 40 is accommodated in the second portion 312. Correspondingly, the second liquid inlet 3120 is opened in a tube wall of the second portion 312. In this embodiment, there are two second liquid inlets 3120. The two second liquid inlets 3120 are symmetrically disposed on two sides of the second portion 312 in a radial direction. Correspondingly, there are also two first liquid inlets 210. The two first liquid inlets 210 are respectively correspondingly provided and in communication with the two second liquid inlets 3120.
An outer diameter of the first portion 311 is slightly smaller than the outer diameter of the second portion 312, and is smaller than the inner diameter of the first outer tube section 21. An outer wall surface of the first portion 311 is in clearance fit with an inner wall surface of the first outer tube section 21, so that in one aspect, a force required to mount the inner tube 30 in the outer tube 20 can be reduced, and in another aspect, an annular vent gap 3110 may be formed between the outer wall surface of the first portion 311 and the inner wall surface of the first outer tube section 21. The annular vent gap 3110 may be configured to form a part of the auxiliary airway 23. It may be understood that, based on the structure of the first inner tube section 31, the air guide groove 310 may be formed only in the second portion 312 of the first inner tube section 31, provided that a lower end of the air guide groove 310 is in communication with an upper end of the annular vent gap 3110. In other embodiments, the outer diameter of the first portion 311 may be equal to the outer diameter of the second portion 312.
The vaporization assembly 40 may include a liquid absorbing body 41 and a heating body 42 in contact with the liquid absorbing body 41. The liquid absorbing body 41 is configured to absorb the liquid substrate from the liquid storage cavity 110 and transfer the liquid substrate to the heating body 42. The heating body 42 is configured to heat and vaporize the liquid substrate after being energized. In this embodiment, the liquid absorbing body 41 is a porous ceramic, and can absorb the liquid substrate from the liquid storage cavity 110 through infiltration and a capillary effect of micropores inside the liquid absorbing body. It may be understood that, in other embodiments, a material of the liquid absorbing body 41 is not limited to a porous ceramic material, and may be another porous material such as liquid absorbing cotton.
The liquid absorbing body 41 may be in a circular cylinder shape, and a vaporization cavity 410 is formed penetrating longitudinally inside the liquid absorbing body. The vaporization cavity 410 is in communication with the main airway 33, and may be coaxially disposed with the main airway 33. The heating body 42 may be disposed in a cavity wall surface of the vaporization cavity 410. In other embodiments, the liquid absorbing body 41 may be in another shape such as a bowl shape or a sheet shape.
The heating body 42 may be a heating film, and may be formed on a blank of the liquid absorbing body 41 in a manner such as screen printing, printing or spraying, and may be sintered and formed together with the liquid absorbing body 41. Alternatively, the heating body 42 may be a separately formed metal heating sheet or metal heating wire.
In some embodiments, the vaporization assembly 40 may further include a liquid guide body 43. The liquid guide body 43 may be made of liquid guide cotton, may be in a circular cylinder shape, may be sleeved between an outer wall surface of the liquid absorbing body 41 and the inner wall surface of the inner tube 30, and is configured to quickly and uniformly transfer the liquid substrate in the liquid storage cavity 110 to the liquid absorbing body 41. It may be understood that, in other embodiments, a material of the liquid guide body 43 is not limited to liquid guide cotton, and may be another porous material such as porous ceramic.
The base 13 is at least partially disposed in an opening at the lower end of the liquid storage shell 11, to block a lower end of the liquid storage cavity 110 in a sealed manner. At least one air inlet hole 1331 may be further opened in the base 13. The at least one air inlet hole 1331 may be configured to form the air inlet channel 130. A first mounting hole 1320 is concave downward to be formed in a top surface of the base 13. Lower ends of the first inner tube section 31 and the first outer tube section 21 may be disposed in the first mounting hole 1320. An outer wall surface of the lower end of the first outer tube section 21 may fit a hole wall surface of the first mounting hole 1320 in a sealed manner, to avoid leakage of the liquid substrate in the liquid storage cavity 110.
A support surface 1321 is provided at a bottom of the first mounting hole 1320. Lower end surfaces of the first inner tube section 31 and the first outer tube section 21 may abut against the support surface 1321, to implement positioning of the first inner tube section 31 and the first outer tube section 21 in the first mounting hole 1320. At least one vent opening 313 that communicates the auxiliary airway 23 with the air inlet channel 130 may be further formed in the first inner tube section 31. In this embodiment, there are two vent openings 313. The two vent openings 313 are symmetrically disposed on two sides of the first inner tube section 31 in the radial direction. Each vent opening 313 is concave upward to be formed in the lower end surface of the first inner tube section 31. It may be understood that, in other embodiments, a quantity of the vent openings 313 is not limited to 2. There may be one or more than two vent openings. In addition, the vent opening 313 may be disposed at another position in the first inner tube section 31, for example, may be disposed close to the lower end of the first inner tube section 31.
In some embodiments, the base 13 may include a base portion 131, an insertion portion 132 extending upward from an upper end surface of the base portion 131, and a butt portion 133 extending downward from a lower end surface of the base portion 131. The insertion portion 132 may be in a circular cylinder shape and inserted in a lower portion of the liquid storage shell 11. At least a part of a peripheral surface of the insertion portion 132 fits the inner wall surface of the liquid storage shell 11 in a sealed manner, to block the lower end of the liquid storage cavity 110 in a sealed manner. The base portion 131 may be in a circular cylinder shape. The upper end surface of the base portion 131 may abut against a lower end surface of the liquid storage shell 11. An outer diameter of the base portion 131 may be consistent with an outer diameter of the lower end of the liquid storage shell 11. The butt portion 133 may be in a circular cylinder shape. An outer diameter of the butt portion 133 may be smaller than the outer diameter of the base portion 131. A threaded structure may be disposed on an outer wall surface of a lower portion of the butt portion 133, and is configured to be threadedly connected to the power supply device 200. The at least one air inlet hole 1331 may be disposed on a sidewall of an upper portion that is of the butt portion 133 and is provided with no threaded structure. In this embodiment, there are two air inlet holes 1331. The two air inlet holes 1331 are symmetrically disposed on two sides of the butt portion 133 in a radial direction.
A second amounting hole 1330 in communication with a lower end of the first mounting hole 1320 may be concave upward to be formed in a bottom surface of the butt portion 133. A hole diameter of the second amounting hole 1330 is smaller than a hole diameter of the first mounting hole 1320, so that the annular support surface 1321 is formed at a connection between the second amounting hole 1330 and the first mounting hole 1320.
An electrode post 16 may further be longitudinally disposed in the first mounting hole 1320. The heating body 42 is electrically connected to the electrode post 16, and is further electrically connected to the power supply device 200 by the electrode post 16. In some embodiments, a material of the base 13 may be a conductive material such as metal. The electrode post 16 is disposed in the first mounting hole 1320 and is electrically insulated from the base 13. Two electrodes of the heating body 42 are respectively connected to the electrode post 16 and the base 13. Generally, an insulating sleeve 15 may be sleeved between an outer wall surface of the electrode post 16 and the hole wall surface of the first mounting hole 1320, to ensure an insulating and sealed connection between the electrode post 16 and the base 13. A material of the insulating sleeve 15 may be generally an insulating material such as silicone or plastic. It may be understood that, in other embodiments, the material of the base 13 may be an insulating material such as plastic.
The electrode post 16 may be a hollow cylinder or a solid column structure. In this embodiment, the electrode post 16 is a hollow cylinder. A through hole 161 is longitudinally formed in the electrode post. The through hole 161 may be used to form the air inlet channel 130. It may be understood that when the through hole 161 is configured to allow air to enter, it may be not necessary to provide the air inlet hole 1331 in the base 13.
An interval is provided between an upper end of the electrode post 16 and a lower end of the vaporization assembly 40, to facilitate thermal insulation. The two electrodes of the heating body 42 may be connected to the electrode post 16 and the base 13 by a first electrode lead 44 and a second electrode lead 45 respectively. An upper end of the first electrode lead 44 is connected to the heating body 42, and a lower end is clamped between the electrode post 16 and the insulating sleeve 15 to be connected to the electrode post 16. An upper end of the second electrode lead 45 is connected to the heating body 42, and a lower end is clamped between the base 13 and the insulating sleeve 15 to be connected to the base 13.
In some embodiments, thermal insulation space 1310 may further be formed on the base 13. The thermal insulation space 1310 can implement thermal insulation and heat preservation, to reduce heat transferred from the base 13 to outside, thereby reducing a heat loss. In this embodiment, the thermal insulation space 1310 is an annular groove, and is longitudinally recessed inward to be formed in a peripheral surface of the base portion 131. Because the base portion 131 has the largest outer diameter, the thermal insulation space 1310 is provided on the base portion 131, so that the thermal insulation space 1310 has a large size, to improve a thermal insulation effect, and heat transferred to the butt portion 133 can be further reduced, to further reduce heat transferred to the power supply device 200.
It may be understood that, in other embodiments, the thermal insulation space 1310 may be in another shape. For example, the thermal insulation space 1310 may include a plurality of thermal insulation grooves provided at intervals. The plurality of thermal insulation grooves may be distributed at intervals in a circumferential direction and/or an axial direction of the base 13. In some other embodiments, the thermal insulation space 1310 may be completely or partially formed in the insertion portion 132 or the butt portion 133. In addition, a thermal insulation medium may be further filled in the thermal insulation space 1310, to further improve the thermal insulation effect.
In some embodiments, the shell 10 may further include a fixing sleeve 14. The fixing sleeve 14 is in a circular cylinder shape and is sleeved at the lower end of the liquid storage shell 11 and outside the base portion 131, so that in one aspect, fixing between the liquid storage shell 11 and the base 13 can be enhanced, and in another aspect, the thermal insulation space 1310 can be sealed.
It may be understood that the foregoing technical features may be used in any combination without limitation.
While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.
The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
