Fig. 1 to 6 are schematic perspective views of an atomizer 100 according to an embodiment of the invention, and a schematic cross-sectional view and a schematic exploded perspective view, respectively. The atomizer 100 is configured to atomize a liquid matrix to generate an aerosol, and may include a housing 10, a support 20, a base 30, a heat generating element 40, and a capillary element 50. The housing 10 may be mounted in cooperation with the base 30 to form an inner space, and thus the holder 20, the heat generating member 40, and the capillary element 50 are mounted and accommodated in the inner space.
Wherein the housing 10 defines a reservoir 11 for storing a liquid matrix. The liquid storage chamber 11 is a receiving space defined in the housing 10 for storing a liquid matrix and supplying the liquid matrix to the capillary element 50. The liquid matrix may be liquid such as tobacco tar and liquid medicine; herein, the liquid matrix 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 flue gas, aerosol or atomized gas. The housing 10 may also provide a mouthpiece portion 12, which may also have a smoke evacuation tube 13 inside; the smoke discharge tube 13 defines a hollow duct for passing therethrough aerosol formed on the atomizing face of the capillary element 50 and discharging through the suction nozzle portion 12.
Referring to fig. 7 and 8, there are shown two perspective views of the bracket 20 of the atomizer 100 of fig. 5; the holder 20 comprises a liquid channel 21 and a first surface 22 and is arranged in the housing 10, the liquid channel 21 is in fluid communication with the liquid reservoir 11, the first surface 22 faces away from the liquid reservoir 11, the liquid channel 21 ends at the first surface 22, and the first surface 22 may surround the liquid channel 21. The bracket 20 may be made of a flexible material such as silicone or thermoplastic elastomer (TPE), which may be inserted into the housing 10 to form a seal with the housing 10. The support 20 may further include a second surface 26 opposite the first surface 22, and the fluid channel 21 extends from the second surface 26 through the support 20 to the first surface 22. The first surface 22 forms a continuous annular surface at the periphery of the liquid passage 21 so as to surround the liquid passage 21.
Referring to fig. 9, a perspective view of the base 30 of the atomizer 100 of fig. 5 is shown; the base 30 is used to support a portion of the heat-generating component 40 and to bring it into contact with the capillary element 50 such that the capillary element 50 is sandwiched between the first surface 22 and the heat-generating component 40. Further, the base 30 may include a receiving cavity 31 and be coupled with the housing 10. For example, the sides of the base 30 may be provided with detents 34 for snap-fitting with corresponding detents 14 on the housing 10. The accommodating cavity 31 may be disposed at a side of the base 30 facing the liquid storage cavity 11, and may be formed by a cylindrical wall or a plurality of protruding portions; the capillary element 50 and the heat generating member 40 are disposed in the accommodating chamber 31.
Referring to fig. 10, a schematic perspective view of the heat generating component 40 of the atomizer 100 shown in fig. 5 is shown; the heat generating member 40 extends substantially flat. Further, the heat generating member 40 may be disposed in the accommodating chamber 31. For example, the heat generating element 40 may be formed in a flat plate shape, and a plurality of through holes are formed in a thickness direction thereof, so that aerosol generated by atomization may be emitted from the capillary element 50 through the through holes. The heating element 40 may be made by punching holes in a sheet material, a heating net structure with meshes may be used, or a circuitous bent line structure may be used. The heating element 40 may be fixedly disposed on the base 30 and located in the accommodating cavity 31.
The capillary element 50 overlies at least a portion of the first surface 22 and blocks the liquid passage 21 for receiving and storing liquid matrix from the liquid reservoir 11 through the liquid passage 21 and delivering liquid matrix to the vicinity of the heat generating member 40. Further, a capillary element 50 may be disposed within the receiving chamber 31 and sandwiched between the first surface 22 and the heat-generating component 40. Capillary element 50 may be made of a material having capillary channels or pores, such as a rigid or rigid capillary structure of cellocotton, porous ceramic body, glass-fiber rope, porous glass-ceramic, porous glass, or the like; the capillary element 50 may be generally planar in shape to conform to the first surface 22 of the holder 20. The capillary element 50 engages the first surface 22 and covers the liquid channel 21, which allows the liquid matrix stored in the liquid reservoir 11 to be transported to the capillary element 50 via the liquid channel 21 without leaking out of the capillary element 50 via the liquid channel 21.
In the atomizer 100 of this embodiment, the base 30 is used to support a part of the heat generating element 40 and make contact with the capillary element 50, and then the housing 10 is used to accommodate the holder 20, so that when the 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 heat generating element 40, and thus the atomizer 100 can be assembled. In this way, the atomizer 100 of the present application is simple in structure and easy to install.
In an alternative embodiment, as shown in connection with fig. 3-8, the atomizer 100 further comprises a support member 60, the support member 60 comprising an aperture 61. The support 60 is arranged between the reservoir 11 and the holder 20, and the opening 61 is in fluid communication with the reservoir 11 and the fluid channel 21. The holder 20 is also provided with a gas channel 23. A ventilation channel 24 is formed between the support 60 and the support 20, and the gas channel 23, the ventilation channel 24 are in fluid communication with the opening 61. The ventilation channel 24 may be a small-bore channel, such as a capillary channel, and when the liquid matrix is contained therein, the adsorption of the liquid matrix and the ventilation channel 24 may act as a plug; only when the pressure in the liquid storage cavity 11 is lower than a certain level, the pressure difference between the external atmosphere and the liquid storage cavity 11 can promote the external air to flow into the liquid storage cavity 11 through the ventilation channel 24. Further, the support 60 may further include a receptacle 62 for the end of the smoke exhaust pipe 13 to pass therethrough. The gas channel 23 may extend from the second surface 26 through the support 20 to the first surface 22. The gas passage 23 may communicate with the outside atmosphere through a space within the base 30. In this way, when the pressure in the liquid storage chamber 11 is reduced, the external air can be supplied into the liquid storage chamber 11 through the base 30, the air passage 23, the ventilation passage 24 and the opening 61, so that the pressure in the liquid storage chamber 11 is substantially balanced with the external environment, and the liquid substrate can be smoothly supplied to the capillary element 50. In some embodiments, the ventilation channel 24 may be provided only on the second surface 26 of the support 20, or may be provided only on the side of the support 60 facing the support 20; alternatively, the ventilation channel 24 may be defined by a recess in the bracket 20 and a recess in the support 60. The support 60 may be made of a rigid material that is in sealing engagement with the second surface 26 of the support 20.
In an alternative embodiment, as shown in fig. 3 to 8, the support member 60 is flat, the ventilation channel 24 is formed on the support 20, and the ventilation channel 24 extends from the gas channel 23 to the liquid channel 21. In this way, the ventilation channels 24 can be made integrally when the bracket 20 is formed; further, by attaching the flat plate-like support member 60 to the bracket 20, the opening above the ventilation passage 24 can be closed, and the ventilation passage 24 communicates with the gas passage 23 and the liquid passage 21 only at both ends.
In an alternative embodiment, as shown in fig. 3 to 8, a liquid guiding groove 25 is further provided on the first surface 22, and the liquid guiding groove 25 extends from the liquid channel 21 to a central area corresponding to the capillary element 50. Since the capillary element 50 is attached to the first surface 22 and covers the liquid channel 21, the liquid medium stored in the liquid storage chamber 11 can be directly delivered to the portion of the capillary element 50 opposite to the liquid channel 21 through the liquid channel 21; in this embodiment, by providing the liquid guide groove 25, the liquid substrate can be directly fed to the central region of the capillary element 50 through the liquid passage 21 and the liquid guide groove 25, so that the rapid supply of the liquid substrate to the central region with a large atomization amount can be ensured. Further, the bracket 20 may include a skirt 20A, the skirt 20A extending from the first surface 22 away from the second surface 26, which may circumferentially surround the upper half 37 of the base 30 for forming a seal between the upper half 37 and the housing 10.
In an alternative embodiment, as shown in fig. 3 to 8, the number of the liquid channels 21 is two, and the liquid guiding groove 25 is communicated between the two liquid channels 21. For example, the liquid guide groove 25 may extend from one of the liquid passages 21 to a central region corresponding to the capillary element 50, and further extend to the other liquid passage 21. Since the cross section of the holder 20 may be generally rectangular or oval, two liquid channels 21 may be provided in a lateral direction of the longer dimension of the holder 20 to supply the capillary element 50 with liquid matrix substantially equally; furthermore, one liquid guiding groove 25 may be used to communicate the two liquid channels 21, such that both liquid channels 21 may supply liquid matrix towards the central area of the capillary element 50. The side of the liquid guide groove 25 facing the capillary element 50 is open, and its cross-sectional area may be substantially constant, or may gradually decrease as approaching the central region of the capillary element 50. Further, the number of the gas passage 23 and the ventilation passage 24 may be two, wherein each ventilation passage 24 communicates with one gas passage 23 and one liquid passage 21.
In an alternative embodiment, as shown in connection with fig. 4 and 8, at least the portion of the first surface 22 around the liquid channel 21 is a cambered surface protruding towards the capillary element 50. The cross section of the cambered surface can be in the shape of an arc, a circular arc and other curves. This embodiment may be applied to a capillary element 50 employing liquid-conducting cotton; specifically, since the liquid-guiding cotton has deformability, the compression seal of the liquid-guiding cotton at the liquid channel 21 can be enhanced by designing such an arc surface, preventing the generation of a gap between the capillary element 50 in the form of liquid-guiding cotton and the first surface 22, and thus preventing the leakage of the liquid matrix through this gap.
In an alternative embodiment, as shown in fig. 3 to 8, the first surface 22 is entirely located in an arc surface A1, 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 shaping of the first surface 22 can be facilitated, while at the same time a pressure-tight sealing of the liquid-conducting cotton at the liquid channel 21 can be achieved.
Further, as shown in fig. 7 and 8, the liquid guiding groove 25 may be formed on the partition plate 27, and the bracket 20 may further include an insertion port 28; the interface 28 faces the partition 27 with an air flow space 29 therebetween. The end of the smoke discharge tube 13 of the housing 10 is insertable into the socket 28. The holder 20 may further comprise a sidewall opening 20B for carrying aerosol generated on the atomizing face of the capillary element 50 with the gas, bypassing the capillary element 50 and entering the gas flow space 29.
In an alternative embodiment, as shown in connection with fig. 2 to 8, the atomizer 100 further comprises an electrode 70, the electrode 70 being inserted in the base 30 and connected to the heat generating member 40; the conductive connection may be achieved, for example, by soldering, plugging, abutment, etc. The electrode 70 may be inserted in the base 30 with a tight fit and one end thereof exposed outwardly from the base 30 for connection with a battery in a power supply assembly. In some embodiments, as shown in connection with fig. 10, the other end of the electrode 70 may be welded to the connection end 41 of the heat generating member 40 by, for example, spot welding. The connecting end 41 of the heating element 40 can be provided with an inserting hole 47; when the electrode 70 is assembled and connected, the electrode 70 can be fixed in the base 30, then the insertion hole 47 of the heating element 40 is sleeved on the other end of the electrode 70, and then the other end of the electrode 70 is welded and connected in the insertion hole 47 in a spot welding mode. In this way, both the electrode 70 and the heat generating member 40 may be fixedly disposed on the base 30.
In an alternative embodiment, as shown in connection with fig. 5 and 9, the base 30 comprises a plurality of protrusions 32 extending towards the reservoir 11, the plurality of protrusions 32 surrounding the receiving cavity 31 and clamping the capillary element 50 within the receiving cavity 31. Further assembly of the base 30 to the housing 10 is facilitated by the use of the protrusions 32 to retain the capillary element 50 within the receiving chamber 31.
In an alternative embodiment, as shown in fig. 5 and 10, the heat generating component 40 includes two connection ends 41 and a heat generating portion 42 extending between the two connection ends 41 in a bending manner. For example, the heat generating portion 42 may include repetitive lines such as an S-shape, a Z-shape, a U-shape, etc., which may be arranged in series. The heating part 42 is further connected with a first reinforcing part 43, and the width of the first reinforcing part 43 is larger than the width of the heating part 42. For example, the number of the first reinforcing parts 43 may be plural, and the self-heating parts 42 may extend in a direction parallel to the longitudinal direction A3 of the capillary element 50; the first reinforcement portion 43 may not be located in the current path, and thus may not generate heat. In this way, since the width of the first reinforcement portion 43 is larger than that of the heat generating portion 42, it can have a higher structural strength than the heat generating portion 42, and thus can play a supporting role for the heat generating portion 42, so that the heat generating member 40 as a whole has a higher strength. For example, in the assembled structure, the first reinforcing portion 43 may be supported on the base 30, so that the heat generating element 40 has sufficient strength to press into the liquid-guiding cotton type capillary element 50, so as to reduce the thickness of the oil film on the atomizing surface of the capillary element 50, thereby reducing the oil frying phenomenon when the atomizer 100 is in use.
In an alternative embodiment, as shown in connection with fig. 10, the cross-sectional shape of the first reinforcing portion 43 is a bent shape. For example, the first reinforcing portion 43 connected to the middle portion of the heat generating portion 42 may be designed to have a bent structure to function as an increase in strength. The cross section of the bending structure can be V-shaped, U-shaped, arc-shaped and the like, and has higher strength compared with the structure with the straight-line cross section. Accordingly, the atomizer 100 according to the embodiment of the present application does not need to separately provide a member for supporting the heat generating member 40, and thus the assembly of the atomizer 100 can be simplified.
In an alternative embodiment, as shown in fig. 10, the heat generating component 40 further includes a second reinforcing portion 44, where the second reinforcing portion 44 is connected to the connection end 41 and the heat generating portion 42, and the second reinforcing portion 44 is disposed parallel to the first reinforcing portion 43. By providing the second reinforcement portion 44, the heat generating member 40 as a whole can be further made to have a high strength.
In an alternative embodiment, as shown in connection with fig. 10, the second reinforcement 44 has a bent cross-sectional shape. By designing the second reinforcement portion 44 to have a bent structure, the effect of increasing strength can be achieved. Similar to the bending structure of the first reinforcing portion 43, the bending structure of the second reinforcing portion 44 may have a V-shaped cross section, a U-shaped cross section, a circular arc shape, etc., which has a higher strength than the structure of the in-line cross section.
In an alternative embodiment, as shown in connection with fig. 5 and 9, the base 30 includes a support beam 33, and the support beam 33 is used to support the first reinforcing portion 43 and avoid the heat generating portion 42. For example, in the assembled structure, the first reinforcing portion 43 may be supported on the support beam 33 of the base 30, and thus the heat generating member 40 is sufficiently strong to be pressed into the wick element 50 in the form of liquid-guiding cotton. The support beam 33 may be an end surface of the support wall 35 within the base 30 facing the heat generating member 40. Further, the base 30 may include an air inlet pipe 36, one end of the air inlet pipe 36 is connected to the outside atmosphere, and the other end may face the heat generating portion 42 of the heat generating member 40.
In an alternative embodiment, as shown in connection with fig. 5 and 9, the support beam 33 includes first and second spaced apart support beams defining an intake area 38 therebetween. The air inlet pipe 36 is disposed in the air inlet area 38, and the end of the air inlet pipe 36 may have a predetermined distance from the heat generating element 40; thus, the air input through the air intake duct 36 may diverge slightly within the air intake area 38 to be able to blow air over at least a majority of the heat generating area of the heat generating component 40.
In an alternative embodiment, as shown in connection with fig. 5, 9 and 10, the heat generating part 42 is bridged between the first and second support beams by the first reinforcing part 43. In this way, the heat generating portion 42 can be stably supported, and thus brought into sufficient contact with the capillary element 50.
In an alternative embodiment, as shown in connection with fig. 5 and 9, the heat generating part 42 includes a parallel line structure 45 at a portion corresponding to the central region of the capillary element 50. For example, the parallel line structure 45 may be a closed loop shape, such as an O-shape, a square shape, a racetrack shape, or the like. Further, the first reinforcement portion 43 may extend from the parallel wiring structure 45 toward the connection end 41; the first reinforcement 43 may be disposed in parallel with the second reinforcement 44. By providing the parallel line structure 45, the amount of heat generated in the area where the parallel line structure 45 is located is reduced, so that the heat in the central area of the heat generating portion 42 can be effectively reduced, and the effect of adjusting the local heat superheat is achieved.
In another alternative embodiment, referring to fig. 5 and 11, fig. 11 is a schematic perspective view of a heat generating component 40 according to another embodiment of the present invention; the heat generating member 40 in this embodiment is substantially the same as the heat generating member 40 shown in fig. 10, and may also include a connection end 41, a bent heat generating portion 42, a first reinforcing portion 43, and a second reinforcing portion 44; the difference is that, in the heat generating component 40 of the embodiment shown in fig. 11, the heat generating portion 42 includes a widened line structure 46 at a portion corresponding to the central region of the capillary element 50, and the width of the widened line structure 46 is greater than the width of other portions of the heat generating portion 42. For example, the first reinforcing portion 43 may extend from the widened line structure 46 along the same square, and both may have the same width. By providing the widened circuit structure 46, the heat productivity of the area where the widened circuit structure 46 is located can be reduced, so that the heat of the central area of the heat generating part 42 can be effectively reduced, and the effect of adjusting the local heat overheat can be achieved. Further, the first reinforcing portion 43 may extend from the widened line structure 46 toward the connection end 41.
Various components of the atomizer 100 of the present invention are described above. The atomizer 100 may constitute an electronic atomizing device with a power supply assembly. When the electronic atomization device with the atomizer 100 needs to be sucked, the power switch of the power supply assembly can be turned on firstly so that the battery supplies power for the heating element 40 of the atomizer 100; then, when the user inhales the mouthpiece portion 12 of the nebulizer 100, the controller in the electronic nebulizing device can start the power supply assembly and the nebulizer 100 to operate according to the inhalation action, and finally generate the aerosol for the user to inhale. The liquid matrix from the liquid storage cavity 11 is heated and atomized by the heating element 40 to form aerosol, and external air can flow through the air inlet pipeline 36 to be conveyed to the atomization surface of the capillary element 50, which is contacted with the heating element 40, and then the formed aerosol is carried to the airflow space 29 by bypassing the capillary element 50 and is discharged through the smoke exhaust pipe 13.
