The atomizer 20 is mounted on top of a battery compartment 90, the battery compartment 90 being used to power and control the atomizer 20. The nebulizer 20 heats and nebulizes an aerosol-forming substrate (e.g., nebulized liquid) stored inside the nebulizer 20 to form an aerosol that can be drawn by a user.

The atomizer 20 comprises an atomizing chamber 21, a suction nozzle 31 located at the top of the atomizing chamber 21, and a bottom assembly 40 mounted to the bottom of the atomizing chamber 21, the suction nozzle 31 having a suction opening 32.

When the user inhales, external air enters the battery compartment air passage inside the battery compartment 90 through the air inlet 92 in the side wall of the housing 91 of the battery compartment 90, and then enters the nebulizing air passage inside the nebulizer 20, and flows out of the air intake 32 after being mixed with the atomized aerosol (aerosol) of the aerosol-forming substrate.

Referring to fig. 2 to 4, the bottom assembly 40 of the atomizer 20 includes a bottom cover 81, the bottom cover 81 includes a first bottom plate 82 and a first flange 87 extending from the periphery of the first bottom plate 82, and the bottom cover 81 is fastened to the bottom of the atomization chamber 21 by the first flange 87. The bottom cover 81 is further provided with an air inlet hole 84 communicating with the outside of the atomizer 20, specifically, the first bottom plate 82 is provided with two air inlet holes 84, the two air inlet holes 84 are communicated with the atomizing air channel inside the atomizer 20, the two air inlet holes 84 are close to the radial outer side of the first bottom plate 82, and preferably, the two air inlet holes 84 are respectively located near two ends of the longer outer diameter of the first bottom plate 82.

It should be noted that in other embodiments, the air inlet holes 84 may also be disposed on the first flange 87.

The end of the battery compartment 90 facing the atomizer 20 has an end cap 95, the end cap 95 is attached to the bottom cover 81 of the atomizer 20 after the product is assembled, and the end cap 95 separates the battery 93 and the circuit components and the like inside the battery compartment 90 from the outside. Preferably, the outer periphery of the end cap 95 is also connected with the inner wall of the housing 91 of the battery compartment 90 through a sealing ring 96. The end cap 95 is provided with two battery compartment gas passages 97, each battery compartment gas passage 97 communicating a respective gas inlet 92 in the side wall of the housing 91 to a respective gas inlet hole 84 of the atomizer 20. In the present embodiment, the battery compartment air duct 97 is formed on the end surface of the end cover 95 facing the atomizer 20 (i.e., the end surface of the end cover 95 abutting against the first bottom plate 82), and more specifically, the end surface of the end cover 95 facing the atomizer 20 is provided with a recess extending radially from the outside to the inside along the end cover 95. The radial opening of the recess faces the gas inlet 92 of the housing 91, and the axial opening of the recess faces the gas inlet hole 84 in a part of the area and is covered by the bottom cover 81 of the atomizer 20 in the other area. In this manner, when the user sucks, external air enters the battery compartment air passage 97 from the air inlet 92 of the housing 91 and then enters the atomization air passage inside the atomizer 20 from the air inlet hole 84.

In the present embodiment, the bottom cover 81 of the atomizer 20 is made of a material that can be attracted by a magnet, and the end cover 95 of the battery compartment 90 is provided with a permanent magnet 98 to attract the bottom cover 81, so as to assemble the atomizer 20 to the battery compartment. After assembly, battery compartment 90 provides power to electrode 65 of atomizer 20 through electrode contact 94 disposed on end cap 95, e.g., battery compartment 90 provides power to atomizer 20 upon detection of a user puff; power to the nebulizer 20 is disconnected when no user puff is detected. Specifically, battery compartment 90 has an airflow sensor (also referred to as a microphone in the industry, not shown), bottom cover 81 of nebulizer 20 has a sensor hole 89 through which the airflow sensor or the airflow sensor can be routed, and sensor hole 89 communicates with the nebulizing air channel inside nebulizer 20 to facilitate the airflow sensor in detecting airflow inside nebulizer 20.

In this embodiment, the benefit of locating gas inlet 92 on the side wall of housing 91 and locating battery compartment gas passage 97 near the radially outer side of end cap 95 is that the air inlet path for atomizer 20 need not pass through the interior of battery compartment 90, thereby reducing backflow of mist or condensate from atomizer 20 through the air flow path to the interior of battery compartment 90, and thus reducing the effect of condensate on the electrical components (e.g., battery 93 and circuit components) within battery compartment 90. In addition, end cover 95 separates internal electrical components such as battery 93 and circuit components inside battery compartment 90 from the outside, and battery compartment air duct 97 from electrode contact 94, and even if a small amount of mist or condensate thereof flows back to battery compartment air duct 97 through the air flow path, the internal electrical components inside battery compartment 90 are not affected. Similarly, the end cap 95 may be provided with a receiving groove 99 at a position corresponding to the sensor hole 89, and the receiving groove 99 is spaced apart from the electrode contact 94, so that even if a small amount of mist or condensate thereof flows back into the receiving groove 99 through the sensor hole 89, the electrical components inside the battery compartment 90 are not affected. In order to further reduce backflow of mist or condensate thereof into the battery compartment 90 through the sensor hole 89, the aperture of the sensor hole 89 is smaller than that of the air intake hole 84.

Referring to fig. 5, the atomization chamber 21 includes a cylindrical housing 22, the cylindrical housing 22 has a partition 24 therein at a position away from the bottom assembly 40, and the cylindrical housing 22 also accommodates a vent pipe 26 therein, the vent pipe 26 extending in the height direction of the atomization chamber 21.

The cylindrical housing 22 of the aerosol chamber 21 forms a reservoir chamber 28 between the outer wall of the vent tube 26 and the inner wall of the aerosol chamber 21 on the side of the partition 24 adjacent the base member 40, the reservoir chamber 28 being for holding an aerosol-forming liquid (i.e. a liquid aerosol-forming substrate). The atomization bin 21 is integrally formed with a suction nozzle 31 at the other side of the partition plate 24. The nozzle cover 33 is disposed on the top end of the air tube 26 and at least partially received in the cylindrical housing 22 to prevent the mouth of the user from touching the top end of the air tube or the top edge of the cylindrical housing 22, so as to improve the appearance of the nozzle 31 and the comfort of the user.

The bottom assembly 40 includes a sealing member 41, a holder 51, an atomizing core 61, a base 71, and a bottom cover 81, which are assembled in sequence or stacked in sequence. The sealing member 41 wraps the top of the support 51, so as to be connected with the inner wall of the atomization bin 21 and the outer wall at the bottom end of the vent pipe 26 in a sealing manner, that is, the sealing member 41 is at least partially located between the support 51 and the inner wall of the atomization bin 21 and partially located between the support 51 and the outer wall at the bottom end of the vent pipe 26, so as to seal a gap between the support 51 and the inner wall of the atomization bin 21 and a gap between the support 51 and the outer wall at the bottom end of the vent pipe 26, and prevent the atomized liquid from leaking outwards through a connection gap between the support 51 and the vent pipe 26 and/or a connection gap between the support 51 and the inner wall of the atomization bin 21. The support 51 is provided with a support airway that communicates with the ventilation tube 26 and forms part of the nebulizing airway of the nebulizer 20. The atomizing core 61 is mounted within the holder 51 and is located in the holder airway. The top of the bracket 51 is also provided with a liquid inlet channel for communicating the liquid storage cavity 28 with the atomizing core 61, so that the atomized liquid in the liquid storage cavity 28 can be supplied to the atomizing core 61 through the liquid inlet channel. The base 71 is located at the bottom end of the support 51, and is used for stably assembling the support 51 into the atomization bin opening at the bottom of the atomization bin 21, and the bottom cover 81 covers the atomization bin opening at the bottom of the atomization bin 21 and is farther away from the center of the atomizer 20 than the base 71.

Referring to fig. 6, the sealing member 41 is cylindrical, the top of the bracket 51 of the sealing member 41 is adapted to the shape of the bracket 51, so that the sealing member 41 can be covered on the top of the bracket 51, and the sealing member 41 can be made of, but not limited to, flexible materials such as silicone rubber, etc. The top of the sealing member 41 is provided with a mounting hole 42 and an oil inlet hole 44, the mounting hole 42 is used for accommodating the bottom end of the vent pipe 26 and is hermetically connected with the outer wall of the vent pipe 26, and the oil inlet hole 44 is communicated with the liquid storage cavity 28 (see fig. 5). The outer periphery of the seal member 41 is provided with a seal flange to enhance the sealing effect with the inner wall of the cylindrical housing 22.

Referring to fig. 7, the bracket 51 includes a first annular wall 55 and a top portion located at the top end of the first annular wall 55, the top portion of the bracket 51 has a through hole 52 communicating with the air pipe 26, and the through hole 52 and the space in the first annular wall 55 together form the above-mentioned bracket air passage and communicate with the air pipe 26. The top of the bracket 51 is also provided with a liquid inlet channel 54, one end of the liquid inlet channel 54 is communicated with the oil inlet hole 44 (see fig. 6) of the sealing element 41, and the other end is communicated with the atomizing core 61. More specifically, as shown in fig. 5, the atomizing core 61 is provided with a concave liquid storage tank 64 on the end surface facing the liquid storage cavity 28, the liquid storage tank 64 is connected with the liquid inlet channel 54, and the liquid storage tank 64 is used for providing the atomized liquid flowing from the liquid storage cavity 28 to the atomizing core 61 through the oil inlet 44 and the liquid inlet channel 54, so that the atomized liquid is continuously provided for the atomizing core 71 when the atomizing core is in operation, and the dry burning problem caused by insufficient oil supply is avoided.

In this embodiment, the first annular wall 55 of the bracket 51 is formed with a hollow 56 to increase the size of the bracket airway. The atomizing core 61 fits into the bracket airway. When the user sucks, external air enters the air passage of the bracket from the air vent 78 of the base 71, is mixed with the atomized aerosol of the atomizing core 61, and then enters the air vent pipe 26 through the through hole 52. In this embodiment, the atomizing core 61 is a ceramic heating element, and includes a porous ceramic member and a heating sheet attached to the surface of the porous ceramic member, and the heating sheet is preferably attached to the end surface of the porous ceramic member close to the base 71 (i.e. the surface away from the reservoir 64), so that the lower portion of the porous ceramic member and the base 71 form an atomizing chamber 58 (see fig. 5), and after entering from the vent hole 78, the external gas is firstly mixed with the aerosol in the atomizing chamber 58 and then enters the vent pipe 26 by bypassing the atomizing core 61, so as to achieve better mixing effect and taste.

Referring to fig. 8 and 9, the base assembly 40 further includes two electrodes 65 for supplying power to the atomizing core 61, and the two electrodes 65 both penetrate through the base 71 and the bottom cover 81 along the height direction of the atomizing chamber 21 to be electrically connected to the two electrode contacts 94 of the battery chamber 90, respectively. The base 71 or the bottom cover 81 presses the atomizing core 61 against the inside of the holder 51 by the two electrodes 65 (refer to fig. 5 and 6).

The base 71 is mounted to the bottom of the atomization chamber 21 for stably fitting the holder 51 to the inner wall of the atomization chamber 21. Base 71 is provided with a vent 77, and vent 77 has a vent 78, through which external air may enter the interior of nebulizer 20 (e.g., into nebulizing chamber 58, the frame airway of frame 51, and vent tube 26, in sequence, during a puff). The bottom cover 81 is mounted to the bottom of the atomization chamber 21, and has a first bottom plate 82 extending along the radial direction of the atomization chamber 21 and a first flange 87 extending from the first bottom plate 82, and the first flange 87 is provided with a bayonet 88 to be fastened to the outer wall of the atomization chamber 21. The first bottom plate 82 is farther from the center of the atomizer 20 than the base 71, and an air groove 73 is formed between the first bottom plate 82 and the base 71. The air channel 73 extends along the surface of the first floor 82 or base 71, i.e. along the surface of the first floor 82 facing the base 71, or along the surface of the base 71 facing the first floor 82, including but not limited to a transverse plane that is generally (inclined or perpendicular) intersecting the longitudinal axis of the aerosol chamber opening, but does not exclude surfaces having local inclinations or irregularities. The air inlet holes 84 of the first bottom plate 82 are arranged at positions offset from the vent holes 78, and the positions of the first bottom plate 82 facing the vent holes 78 are not perforated, so that the outside air can enter the inside of the atomizer 20 through the vent holes 78 via the air grooves 73. In this embodiment, the atomizer 20 is separated from the battery compartment 90 by the bottom cover 81, and the bottom cover 81 is not opened at a position facing the vent hole 78, so that the liquid condensed from the vent hole 78 does not directly enter the battery compartment 90. The bottom cover 81 and the base 71 of the atomizer 20 form a transverse air groove 73, external air can reach the vent hole 78 through the air groove 73, accordingly, liquid condensed out from the vent hole 78 can flow to the outside only through the air groove 73, and the overflow risk is reduced. Further, as shown in fig. 8, the side of the base 71 facing the atomizing core 61, which is convex toward the atomizing core 61 at a position corresponding to the vent hole 78, reduces the risk of condensate entering the atomizing chamber 58 into the vent hole 78, thereby reducing the risk of condensate flowing to the bottom cover 81 via the vent hole 78.

In this embodiment, the base 71 includes a second annular wall 74 extending along the height direction of the atomization chamber 21, and a second bottom plate 72 accommodated in the second annular wall 74 and connected to the inner wall of the second annular wall 74. The second annular wall 74 abuts against the inner wall of the atomization bin 21, one end, close to the bottom cover 81, of the second annular wall 74 is provided with an outward second flanging 76, and the second flanging 76 abuts against the tail end of the atomization bin 21 for limiting during assembly. The air groove 73 is formed between the first bottom plate 82 and the second bottom plate 72. The second annular wall 74 has a gap 75 in communication with the air groove 73. The first bottom plate 82 is provided with air inlet holes 84 at positions corresponding to the notches 75, and external air can enter the air groove 73 through the air inlet holes 84. Air inlet hole 84 of bottom cover 81 is close to the outside of bottom cover 81, so that the air inlet channel is located on the outer wall of battery compartment 90 as much as possible, and the air channel of the battery compartment 90 does not need to pass through the area inside battery compartment 90, thereby further reducing the influence of the condensate of atomizer 20 on the internal components of battery compartment 90, such as battery 93.

The bottom cover 81 is provided with two electrode through holes 83 for the electrodes 65 to pass through so as to be electrically connected with the electrode contacts of the battery compartment 90. The base assembly 40 further includes an electrode seal 79 sandwiched between the first base plate 82 and the second base plate 72, the electrode seal 79 being provided with an electrode hole for the electrode 65 to pass through. The gas groove 73 is located outside the electrode seal holder 79. In this case, the air flow from the air intake holes 84 into the air groove 73 is shown by an arrow F in fig. 9.

The base 71 and the vent 77 may be integrally formed, i.e., the base 71 and the vent 77 are a unitary structure. It is understood that the base 71 and the vent 77 may be formed separately, i.e., the base 71 and the vent 77 are a split structure.

Fig. 10 shows the base 71 and the vent member 77 formed separately, and the vent member 77 includes a vent portion having a vent hole 78 and two electrode sealing portions 79 respectively connected to both sides of the vent portion. The air passage member 77 is attached to the second bottom plate 72 of the base 71 from the outside to the inside (preferably, to the side of the second bottom plate 72 close to the bottom cover 81), and accordingly, the second bottom plate 72 of the base 71 is provided with a first through hole through which the top end of the air passage portion of the air passage member 77 passes and a second through hole against which the electrode seal 79 is located. The structure after assembly is substantially the same as that shown in fig. 8 and 9.

It should be noted that in other embodiments, the vent 77 may only include a vent portion, and the electrode sealing portion 79 is a portion of the base 71. That is, the electrode seal 79 is integral with the vent and/or base 71.

The above examples merely represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications, such as combinations of different features in various embodiments, may be made without departing from the spirit of the utility model, and these are within the scope of the utility model.
