In addition, technical features involved in different embodiments of the present invention described below may be combined together if there is no conflict between each other.
With reference to FIG. 1 to FIG. 6, FIG. 1 to FIG. 6 are respectively a three-dimensional assembly schematic view, a schematic cross-sectional view, and a schematic three-dimensional exploded view of an atomizer 100 according to an embodiment of the present invention. The atomizer 100 is configured to atomize a liquid substrate to generate an aerosol, and may include a housing 10, a holder 20, a bottom base 30, a heating member 40, and a capillary element 50. The housing 10 may be mounted in cooperation with the bottom base 30 to form an internal space, so that the holder 20, the heating member 40, and the capillary element 50 are mounted and accommodated in the internal space.
The housing 10 defines a liquid storage cavity 11 for storing the liquid substrate. The liquid storage cavity 11 is an accommodating space defined in the housing 10, and is configured to store the liquid substrate and supply the liquid substrate to the capillary element 50. The liquid substrate may be, for example, a liquid such as an e-liquid or a chemical solution. In this specification, the liquid substrate may also be referred to as a liquid, the atomization may also be referred to as vaporization, and the aerosol may also be referred to as smoke, vapor, or atomized vapor. The housing 10 may be further provided with a mouthpiece portion 12, and the housing 10 may further have a discharging pipe 13 inside. The discharging pipe 13 defines a hollow pipe for an aerosol formed on an atomization surface of the capillary element 50 to pass through and be discharged through the mouthpiece portion 12.
With reference to FIG. 7 and FIG. 8, FIG. 7 and FIG. 8 are two schematic three-dimensional diagrams of a holder 20 of the atomizer 100 shown in FIG. 5. The holder 20 includes a liquid passage 21 and a first surface 22 and is arranged in the housing 10. The liquid passage 21 is in fluid communication with the liquid storage cavity 11. The first surface 22 faces away from the liquid storage cavity 11. The liquid passage 21 ends at the first surface 22. The first surface 22 may surround the liquid passage 21. The holder 20 may be made of a flexible material such as silicone or a thermoplastic elastomer (TPE), and may be inserted into the housing 10 to form a seal with the housing 10. The holder 20 may further include a second surface 26 facing away from the first surface 22. The liquid passage 21 extends from the second surface 26 to the first surface 22 through the holder 20. The first surface 22 forms a continuous annular surface at a periphery of the liquid passage 21 to surround the liquid passage 21.
With reference to FIG. 9, FIG. 9 is a schematic three-dimensional diagram of a bottom base 30 of the atomizer 100 shown in FIG. 5. The bottom base 30 is configured to support a part of the heating member 40 and bring the heating member 40 into contact with the capillary element 50, so that the capillary element 50 is clamped between the first surface 22 and the heating element 40. Further, the bottom base 30 may include an accommodating cavity 31 and is connected to the housing 10. For example, a block 34 may be provided on a side surface of the bottom base 30 for engagement with a corresponding slot 14 on the housing 10. The accommodating cavity 31 may be arranged on a side of the bottom base 30 facing the liquid storage cavity 11. The accommodating cavity 31 may be surrounded by a cylindrical wall, or may be surrounded by a plurality of protruding portions 32. The capillary element 50 and the heating member 40 are arranged in the accommodating cavity 31.
With reference to FIG. 10, FIG. 10 is a schematic three-dimensional diagram of a heating member 40 of the atomizer 100 shown in FIG. 5. The heating member 40 extends substantially flat. Further, the heating member 40 may be arranged in the accommodating cavity 31. For example, the heating member 40 may be in a shape of a flat plate as a whole, and a plurality of through holes are provided in a thickness direction, so that the aerosol generated through atomization can be dispersed away through the through holes in a direction away from the capillary element 50. The heating member 40 may be made by perforating a sheet material, or may be a heating mesh structure having mesh holes, or may be a circuit structure with winding bends. The heating member 40 may be fixedly arranged on the bottom base 30 and located in the accommodating cavity 31.
The capillary element 50 covers at least a part of the first surface 22 and blocks the liquid passage 21, and is configured to receive and store the liquid substrate from the liquid storage cavity 11 through the liquid passage 21, and convey the liquid substrate to a vicinity of the heating member 40. Further, the capillary element 50 may be arranged in the accommodating cavity 31 and clamped between the first surface 22 and the heating member 40. The capillary element 50 may be made of a material having capillary passages or pores, for example, a hard or rigid capillary structure such as a cotton fiber, a porous ceramic body, a glass fiber rope, a porous glass ceramic, or a porous glass. The capillary element 50 may be substantially in a shape of a flat plate, to fit the first surface 22 of the holder 20. The capillary element 50 fits the first surface 22, thereby covering the liquid passage 21. This enables the liquid substrate stored in the liquid storage cavity 11 to be conveyed to the capillary element 50 through the liquid passage 21 without leaking to a component outside the capillary element 50 through the liquid passage 21.
In the atomizer 100 in this embodiment, the bottom base 30 is used to support the part of the heating member 40 and bring the heating member 40 into contact with the capillary element 50, and then the housing 10 accommodates the holder 20. Therefore, when the bottom base 30 is connected to the housing 10, the capillary element 50 can be clamped between the first surface 22 of the holder 20 and the heating member 40, thereby implementing assembly of the atomizer 100. In this way, the atomizer 100 in this application has a simple structure and is easy to mount.
In an optional embodiment, with reference to FIG. 3 to FIG. 8, the atomizer 100 further includes a supporting member 60. The supporting member 60 includes an opening hole 61. The supporting member 60 is arranged between the liquid storage cavity 11 and the holder 20, and the opening hole 61 is in fluid communication with the liquid storage cavity 11 and the liquid passage 21. The holder 20 is further provided with an air passage 23. A ventilation passage 24 is formed between the supporting member 60 and the holder 20, and the air passage 23 and the ventilation passage 24 are in fluid communication with the opening hole 61. The ventilation passage 24 may be a small-diameter passage such as a capillary passage. When the liquid substrate is included in the ventilation passage 24, blocking may be achieved through the adsorption between the liquid substrate and the ventilation passage 24. Only when a pressure in the liquid storage cavity 11 is lower than a specific level, a pressure difference between external air and the liquid storage cavity 11 may cause the external air to flow into the liquid storage cavity 11 through the ventilation passage 24. Further, the supporting member 60 may further include an insertion hole 62 for allowing an end of the discharging pipe 13 to pass through. The air passage 23 may extend from the second surface 26 to the first surface 22 through the holder 20. The air passage 23 may be in communication with the external air through the space in the bottom base 30. In this way, when the pressure in the liquid storage cavity 11 decreases, the external air can be conveyed to the liquid storage cavity 11 through the bottom base 30, the air passage 23, the ventilation passage 24, and the opening hole 61, so that the pressure in the liquid storage cavity 11 is approximately balanced with that of the outside, and the liquid substrate can be smoothly supplied to the capillary element 50. In some embodiments, the ventilation passage 24 may be arranged only on the second surface 26 of the holder 20, or may be arranged only on a side of the supporting member 60 facing the holder 20. Alternatively, the ventilation passage 24 may be jointly surrounded by a groove on the holder 20 and a groove on the supporting member 60. The supporting member 60 may be made of a hard material, and the supporting member 60 may be in a sealed fit with the second surface 26 of the holder 20.
In an optional embodiment, with reference to FIG. 3 to FIG. 8, the supporting member 60 is in a shape of a flat plate, the ventilation passage 24 is arranged on the holder 20, and the ventilation passage 24 extends from the air passage 23 to the liquid passage 21. In this way, the ventilation passage 24 may be integrally formed when the holder 20 is formed. In addition, the flat plate-shaped supporting member 60 fits the holder 20, so that an opening above the ventilation passage 24 can be closed, and the ventilation passage 24 is in communication with the air passage 23 and the liquid passage 21 only at two ends.
In an optional embodiment, with reference to FIG. 3 to FIG. 8, a liquid guide groove 25 is further provided on the first surface 22. The liquid guide groove 25 extends from the liquid passage 21 to a central region corresponding to the capillary element 50. Since the capillary element 50 fits the first surface 22 and covers the liquid passage 21, the liquid substrate stored in the liquid storage cavity 11 can be directly conveyed to a part of the capillary element 50 exactly opposite to the liquid passage 21 through the liquid passage 21. In this embodiment, the liquid guide groove 25 is provided, so that the liquid substrate can be directly conveyed to the central region of the capillary element 50 through the liquid passage 21 and the liquid guide groove 25, thereby ensuring that the liquid substrate is quickly supplied to a central region requiring a large amount of atomization. Further, the holder 20 may include a flange portion 20A. The flange portion 20A extends from the first surface 22 away from the second surface 26, and may circumferentially surround an upper half 37 of the bottom base 30, to form a seal between the upper half 37 and the housing 10.
In an optional embodiment, with reference to FIG. 3 to FIG. 8, the number of liquid passages 21 is two, and the liquid guide groove 25 is in communication with the two liquid passages 21. For example, the liquid guide groove 25 may extend from one of the liquid passages 21 to the central region corresponding to the capillary element 50, and further extend to the other liquid passage 21. Since a cross section of the holder 20 may usually be rectangular or elliptical, two liquid passages 21 may be arranged on the holder 20 in a lateral direction in which the holder 20 has a longer dimension, to supply the liquid substrate to the capillary element 50 in a roughly even manner. Further, one liquid guide groove 25 may be used to be in communication with the two liquid passages 21, so that both the two liquid passages 21 can supply the liquid substrate toward the central region of the capillary element 50. A side of the liquid guide groove 25 facing the capillary element 50 is open, and a cross-sectional area of the liquid guide groove 25 may be approximately constant, or may gradually decrease as the liquid guide groove approaches the central region of the capillary element 50. Further, the number of air passages 23 and the number of ventilation passages 24 may both be two. Each ventilation passage 24 is in communication with one air passage 23 and one liquid passage 21.
In an optional embodiment, with reference to FIG. 4 and FIG. 8, at least a part of the first surface 22 around the liquid passage 21 is an arc surface protruding toward the capillary element 50. A cross section of the arc surface may be in a curved shape such as an arc or a circular arc. This embodiment is applicable to the capillary element 50 using a liquid guide cotton. Specifically, due to the deformability of the liquid guide cotton, the design of this arc surface can strengthen the compression and sealing of the liquid guide cotton at the liquid passage 21, to prevent a gap from being formed between the capillary element 50 in the form of the liquid guide cotton and the first surface 22, thereby preventing the liquid substrate from leaking through the gap.
In an optional embodiment, with reference to FIG. 3 to FIG. 8, the first surface 22 is entirely located in an arc surface Al, and a central axis A2 of the arc surface A1 is parallel to a length direction A3 of the capillary element 50. In this way, the design and manufacture of the first surface 22 can be facilitated. In addition, the liquid guide cotton can be compressed and sealed at the liquid passage 21.
Further, with reference to FIG. 7 and FIG. 8, the liquid guide groove 25 may be provided on a baffle plate 27, and the holder 20 may further include an insertion opening 28. The insertion opening 28 is opposite to the baffle plate 27, and an airflow space 29 exists between the insertion opening 27 and the baffle plate 27. An end of the discharging pipe 13 of the housing 10 may be inserted into the insertion opening 28. The holder 20 may further include a side wall opening 20B for a gas to carry an aerosol generated on an atomization surface of the capillary element 50 to bypass the capillary element 50 and enter the airflow space 29.
In an optional embodiment, with reference to FIG. 2 to FIG. 8, the atomizer 100 further includes an electrode 70. The electrode 70 is inserted into the bottom base 30 and is connected to the heating member 40. For example, conductive connection may be implemented through soldering, insertion, or abutment. The electrode 70 may be inserted into the bottom base 30 in a tight fit, and one end of the electrode 70 is exposed outward from the bottom base 30, to be connected to a battery in a power supply assembly. In some embodiments, with reference to FIG. 10, another end of the electrode 70 may be connected to a connection end 41 of the heating member 40 through, for example, spot soldering. An insertion hole 47 may be provided at the connection end 41 of the heating member 40. During assembly and connection with the electrode 70, the electrode 70 may be fixed in the bottom base 30 first, the insertion hole 47 of the heating member 40 is sleeved over the other end of the electrode 70, and then the other end of the electrode 70 is connected to the insertion hole 47 through spot soldering. In this way, both the electrode 70 and the heating member 40 can be fixedly arranged on the bottom base 30.
In an optional embodiment, with reference to FIG. 5 and FIG. 9, the bottom base 30 includes a plurality of protruding portions 32 extending toward the liquid storage cavity 11. The plurality of protruding portions 32 surround the accommodating cavity 31 and clamp the capillary element 50 in the accommodating cavity 31. The capillary element 50 is clamped in the accommodating cavity 31 by using the protruding portions 32, to facilitate further assembly and connection of the bottom base 30 with the housing 10.
In an optional embodiment, with reference to FIG. 5 and FIG. 10, the heating member 40 includes two connection ends 41 and a heating portion 42 bent and extending between the two connection ends 41. For example, the heating portion 42 may include repetitive circuits of an S-shape, a Z-shape, a U-shape, or the like. These repetitive circuits may be arranged in series. A first reinforcing portion 43 is further connected to the heating portion 42, and the width of the first reinforcing portion 43 is greater than the width of the heating portion 42. For example, there may be a plurality of first reinforcing portions 43, and the first reinforcing portion 43 may extend from the heating portion 42 in a direction parallel to the length direction A3 of the capillary element 50. The first reinforcing portion 43 may not be located in a current path, and therefore, the first reinforcing portion 43 may not generate heat. In this way, since the width of the first reinforcing portion 43 is greater than the width of the heating portion 42, the first reinforcing portion 43 may have higher structural strength than that of the heating portion 42, and the first reinforcing portion 43 can support the heating portion 42, so that the heating member 40 as a whole has higher strength. For example, in an assembly structure, the first reinforcing portion 43 may be supported on the bottom base 30, so that the heating member 40 has sufficient strength to be pressed into the capillary element 50 in the form of the liquid guide cotton, to reduce a thickness of an e-liquid film on the atomization surface of the capillary element 50, thereby reducing an e-liquid splashing phenomenon during use of the atomizer 100.
In an optional embodiment, with reference to FIG. 10, a cross-sectional shape of the first reinforcing portion 43 is curved. For example, the first reinforcing portion 43 connected to a middle part of the heating portion 42 may be designed to have a bent structure, to increase strength. A cross section of the bent structure may be of a V-shape, a U-shape, a circular arc, or the like, which has higher strength than a structure with a one-line cross section. Correspondingly, the atomizer 100 in the embodiments of this application does not need to be separately provided with a component for supporting the heating member 40, so that assembly of the atomizer 100 can be simplified.
In an optional embodiment, with reference to FIG. 10, the heating member 40 further includes a second reinforcing portion 44. The second reinforcing portion 44 is connected to the connection end 41 and the heating portion 42. The second reinforcing portion 44 is arranged in parallel with the first reinforcing portion 43. Through arrangement of the second reinforcing portion 44, the heating member 40 as a whole can further have higher strength.
In an optional embodiment, with reference to FIG. 10, a cross-sectional shape of the second reinforcing portion 44 is curved. The second reinforcing portion 44 is designed to have a bent structure, to increase strength. Similar to the bent structure of the first reinforcing portion 43, a cross section of the bent structure of the second reinforcing portion 44 may be of a V-shape, a U-shape, a circular arc, or the like, which has higher strength than a structure with a one-line cross section.
In an optional embodiment, with reference to FIG. 5 and FIG. 9, the bottom base 30 includes a supporting beam 33. The supporting beam 33 is configured to support the first reinforcing portion 43 and avoid the heating portion 42. For example, in the assembly structure, the first reinforcing portion 43 may be supported on the supporting beam 33 of the bottom base 30, so that the heating member 40 has sufficient strength to be pressed into the capillary element 50 in the form of the liquid guide cotton. The supporting beam 33 may be an end surface of a supporting wall 35 in the bottom base 30 facing the heating member 40. Further, the bottom base 30 may include an air inlet tube 36. One end of the air inlet tube 36 is in communication with the external air, and the other end may be exactly opposite to the heating portion 42 of the heating member 40.
In an optional embodiment, with reference to FIG. 5 and FIG. 9, the supporting beam 33 includes a first supporting beam 331 and a second supporting beam 332 that are spaced apart from each other. An air inlet region 38 is formed between the first supporting beam 331 and the second supporting beam 332. The air inlet tube 36 is arranged in the air inlet region 38, and an end of the air inlet tube 36 may have a preset distance from the heating member 40. Therefore, the air inputted through the air inlet tube 36 may slightly dispersed in the air inlet region 38, so that the air can be blown onto at least most of a heating region of the heating member 40.
In an optional embodiment, with reference to FIG. 5, FIG. 9, and FIG. 10, the heating portion 42 is arranged between the first supporting beam 331 and the second supporting beam 332 through the first reinforcing portion 43. In this way, the heating portion 42 can be stably supported, so that the heating portion 42 is in full contact with the capillary element 50.
In an optional embodiment, with reference to FIG. 5 and FIG. 10, the heating portion 42 includes a parallel circuit structure 45 in a part corresponding to the central region of the capillary element 50. For example, the parallel circuit structure 45 may be a closed ring, such as an O-shape, a square shape, or a racetrack shape. Further, the first reinforcing portion 43 may extend from the parallel circuit structure 45 toward the connection end 41; and the first reinforcing portion 43 may be arranged in parallel with the second reinforcing portion 44. Through arrangement of the parallel circuit structure 45, an amount of heat generated in a region in which the parallel circuit structure 45 is located is reduced, so that heat in a central region of the heating portion 42 can be effectively reduced, thereby regulating local overheating.
In another optional embodiment, with reference to FIG. 5 and FIG. 11, FIG. 11 is a schematic three-dimensional diagram of a heating member 40 according to another embodiment of the present invention. The heating member 40 in this embodiment is substantially the same as the heating member 40 shown in FIG. 10, and may also include a connection end 41, a curved heating portion 42, a first reinforcing portion 43, and a second reinforcing portion 44. A difference between the two is that, in the heating member 40 in the embodiment shown in FIG. 11, the heating portion 42 includes a widened circuit structure 46 in a part corresponding to the central region of the capillary element 50. The width of the widened circuit structure 46 is greater than the width of another part of the heating portion 42. For example, the first reinforcing portion 43 may extend from the widened circuit structure 46 in the same direction, and the first reinforcing portion 43 may have the same width with the widened circuit structure 46. Through arrangement of the widened circuit structure 46, an amount of heat generated in a region in which the widened circuit structure 46 is located is reduced, so that heat in a central region of the heating portion 42 can be effectively reduced, thereby regulating local overheating. Further, the first reinforcing portion 43 may extend from the widened circuit structure 46 toward the connection end 41.
The foregoing describes various components of the atomizer 100 of the present invention. The atomizer 100 may form an electronic atomization device with the power supply assembly. When inhalation needs to be performed on the electronic atomization device having the atomizer 100, a power switch of the power supply assembly may be turned on first, so that the battery can supply power to the heating member 40 of the atomizer 100. Then, when a user inhales into the mouthpiece portion 12 of the atomizer 100, a controller in the electronic atomization device may start the power supply assembly and the atomizer 100 to work based on an inhalation action, to finally generate an aerosol for the user to inhale. The liquid substrate from the liquid storage cavity 11 is heated and atomized by the heating member 40 to form vapor. The external air may flow through the air inlet tube 36 to be conveyed to an atomization surface of the capillary element 50 that is in contact with the heating member 40. Then, the formed aerosol is carried to the airflow space 29 by bypassing the capillary element 50, so that the formed aerosol is discharged through the discharging pipe 13.
