In some embodiments, each of the first, second, and third fluid-conducting holes 331, 314, and 241 is two in number so that the liquid matrix can be uniformly transferred to the fluid-conducting member 22. Since the first sealing member 33 is closely attached to the surface of the upper frame 31, the first and second fluid guide holes 331 and 314 have substantially the same contour shape. The second liquid guiding hole 314 extends through the base portion 311 of the entire upper bracket 31 and extends longitudinally to the inside of the receiving cavity 313.

The lower bracket 32 includes a main body 321 and a connecting arm 322, and the main body 321 of the lower bracket 32 is substantially plate-shaped and covers the open end of the housing 10. The connecting arm 322 of the lower rack 32 includes a first connecting arm 3221 and a second connecting arm 3222. The lower bracket 32 and the upper bracket 31 are engaged with each other.

The main body portion 321 of the lower bracket 32 encloses an open interior 323. The electrode connector 40 and the magnetic element 41 are fixed to the main body 321 of the lower holder 32. The electrode connector 40 may be two electrode posts, a positive electrode post and a negative electrode post, respectively. The cylindrical portion of the electrode connection 40 extends longitudinally along the housing 10 to make an electrically conductive connection with the electrically conductive contact of the heating element 21. When the atomizer 100 is combined with a power module, the other end of the electrode connecting member 40 is connected to an electrode connecting member inside the power module. The magnetic member 41 magnetically interacts with a magnetic attraction member inside the power module, thereby stably connecting the nebulizer 100 to the power module. The two magnetic elements 41 are disposed outside the two electrode connectors 40, so that the electrode connectors 40 on the atomizer 100 and the electrode connectors in the power module can be stably contacted to provide power supply.

An air inlet 42 is provided in the main body 321 of the lower holder 32, and the air inlet 42 guides outside air into the atomizing chamber 23. In some embodiments, in order to prevent the condensate from leaking to the outside through the air inlet 42, a liquid blocking structure is provided in the vicinity of the air inlet 42. For example, an air inlet column 421 is disposed on the main body 321, an inner hole of the air inlet column 421 defines the air inlet 42, and an air outlet end of the air inlet column 421 is disposed above the surrounding plane, so that the air inlet 42 is higher in topography toward one end of the atomizing chamber 24, and condensate is difficult to enter the air inlet 42. A plurality of wicking elements, such as wicking cotton or wicking fibers, may also be disposed within the interior 323 of the lower rack 32 and may be sufficient to absorb and store a portion of the condensate or other liquid matrix.

The inner cavity 323 of the lower holder 32 is disposed opposite to the nebulization chamber 23, and in order to prevent aerosol inside the nebulization chamber 23 from dispersing into the inner cavity 323 of the lower holder 32, a second sealing element 34 is disposed in the inner cavity 323 of the lower holder 32. The second sealing element 34 can cover the open end of the inner cavity 323 of the lower bracket 32, and the aerosol in the atomizing chamber 23 is blocked by the upper surface of the second sealing element 34 and is difficult to diffuse into the inner cavity 323 of the lower bracket 32. A first set of two holes is also provided in the second sealing element 34, through which two electrode connections 40 pass, respectively. A vent hole 343 is provided in the second seal member 34, and the vent hole 343 communicates with the intake port 42. In some embodiments, the area adjacent to the vent hole 343 on the second sealing member 34 is provided as a ridge 344. The second sealing element 34 is also provided, on the side facing the atomizing chamber 23, with a flow dividing structure 345 and with a plurality of flow-guiding openings 346, along which the condensate is directed to the various flow-guiding openings 346, through which openings 346 the liquid can enter the inner cavity 323 of the lower bracket 32. The flow dividing structure 345 is disposed on both sides of the raised structure 344, and the flow dividing structure 345 includes inclined surfaces obliquely disposed from the raised portion 344 to both sides and flat paths extending from the bottom ends of the inclined surfaces to the drainage ports 346. In some embodiments, two sets of flow dividing structures 345 and four flow guiding openings 346 are symmetrically disposed on the second sealing member 34, and since the vent holes 343 are surrounded by the ridges 344, liquid in the vicinity of the vent holes 343 can pass along the flow dividing structures 343 into the flow guiding openings 346 and finally into the inner cavity 323 of the lower bracket 32, and due to the arrangement of the ridges 344, the flow dividing structures 345 and the flow guiding openings 346, the entrance of condensate or other liquid from the vent holes 343 into the interior of the air inlet 42 can be avoided or minimized. In some embodiments, the second sealing element 34 is provided with a boss 347 having a hollow interior on a side facing the air inlet 42, and the boss 347 is located in an area at least partially overlapping with an area of the vent hole 343. At least a portion of the inlet column 421 is received in the interior cavity of the boss 347 so that the air flow output through the inlet port 42 can enter directly into the vent 343 along the longitudinal direction of the housing 10. In some embodiments, the second seal 34 is generally boat shaped, with a portion of the wall of the second seal 34 enclosing a condensate collection area 348, the condensate collection area 348 being located on either side of the vent 343, and the condensate collection area 348 being lower in topography than the vicinity of the condensate collection area, facilitating condensate flow to the condensate collection area 348. A second set of apertures is also provided in the second seal 34 through which condensate within the condensate collection region 348 may pass into the internal cavity 323 of the lower support 32.

The liquid substrate in the liquid storage cavity 11 is transferred to the porous liquid guiding element 22 through the liquid guiding channel, and the liquid substrate is atomized by the heating element 21 to form aerosol. As the liquid medium in the liquid storage cavity 11 is consumed, the space occupied by the gas increases, and negative pressure is formed in the liquid storage cavity 11, so that the liquid medium is difficult to enter the liquid guide channel and then is transferred to the liquid guide element 22. In order to prevent negative pressure from being formed inside the liquid storage cavity 11, a ventilation channel for communicating the atomizing cavity 23 with the liquid storage cavity 11 is arranged inside the shell 10, and air flow inside the atomizing cavity 23 can enter the liquid storage cavity 11 through the ventilation channel. In some embodiments, the ventilation channel is disposed between the first sealing element 33 and the upper bracket 31. For example, the columnar portion 332 is provided in the first sealing member 33, the hole 315 is provided in the base portion 311 of the upper holder 31, and the columnar portion 332 can be accommodated in the hole 315. A plurality of air exchange grooves 316 are arranged on the inner wall of the hole 315 at intervals, one end of each air exchange groove 316 is communicated with the atomizing cavity 23, and the other end of each air exchange groove 316 is communicated with the liquid storage cavity 11. Further, a plurality of air guide grooves 317 are formed on the outer surface of the upper bracket 31, and a part of the air flow inside the atomizing chamber 23 enters the air exchange groove 316 through the air guide grooves 317. The number of the column portions 332 and the holes 315 may be set to be plural according to the design requirement of the nebulizer 100, so as to improve the ventilation capability of the ventilation channel.

An air outlet structure allowing aerosol to be output is arranged on the upper support 31 and the first sealing element 33. In some embodiments, referring to fig. 3, 6 to 8, the first support arm 3121 and the second support arm 3122 of the upper bracket 31 are intermittently disposed to form two oppositely disposed notches 318, one end of the notch 318 extends to the atomizing surface 222 of the liquid guiding member 22, and the other end of the notch 318 extends to the top wall 3131 of the receiving cavity 313. The gap 318 is configured to allow aerosol to pass along the surface of the upper support 31 into the outlet tube 12. The base portion 311 of the upper holder 31 is further provided with a first through hole 319, the first sealing member 33 is provided with a second through hole 333, and at least a part of a wall defining the second through hole 333 is attached to an inner wall of the first through hole 319. The outlet pipe 12 comprises an inlet end 121 and an outlet end 122 which are oppositely arranged, aerosol can enter the inner cavity of the outlet pipe 12 through the inlet end 121, and aerosol enters the mouthpiece 110 through the outlet 122. The aerosol formed inside the atomizing chamber 23 can enter the outlet pipe 12 through the first through hole 319 and/or the second through hole 333. In some embodiments, the airflow inlet of the inlet end 121 of the outlet tube 12 extends into the first through hole 319. The outer wall of the outlet tube 12 abuts against the inner wall of the first sealing element 31 to prevent liquid from entering the interior of the outlet tube 12.

In order to avoid the phenomenon that aerosol is formed inside the atomizing cavity 23, the aerosol forms condensate when encountering cold air before entering the outlet pipe 12 or inside the outlet pipe 12, and the condensate can be sucked by a user along with the aerosol, a flow guide piece 50 is arranged inside the shell 10, one end of the flow guide piece 50 is arranged close to the atomizing component 20, the other end of the flow guide piece 50 is close to an airflow inlet of the air inlet end 121 of the outlet pipe 12 or part of the surface of the flow guide piece 50 is contacted with the air inlet end 121 of the outlet pipe 12, so that the condensate is contacted with the surface of the flow guide piece 50 before reaching the airflow inlet of the air inlet end 121 of the outlet pipe 12, and the condensate can flow in the direction close to the atomizing component 20 along the flow guide piece 50. Further, the baffle 50 extends in a direction substantially perpendicular to the axial direction of the outlet tube 12 and across the air flow inlet at the inlet end 121 of the outlet tube 12, so that aerosol entrained with condensate will preferentially contact the baffle 50 before entering the outlet tube 12, and condensate entrained with aerosol will preferentially be directed by the baffle 50 towards the atomizing assembly 20. In some embodiments, the other end of the flow guide 50 extends to the interior of the outlet tube 12, and condensate formed in the interior of the outlet tube 12 may flow along the flow guide 50 toward the atomizing assembly 20, thereby preventing the condensate from flowing toward the nozzle opening 110. Further, one end of the guiding element 50 abuts against the air inlet end 121 of the air outlet tube 12, and the condensate can flow onto the surface of the guiding element 50 along the inner wall of the air outlet tube 12, and then flow to the atomizing assembly 20. The flow guide member 50 comprises a length direction and a width direction, and the length direction of the flow guide member 50 is vertical to the longitudinal direction of the shell 10; the width direction of the baffle 50 is parallel to the longitudinal direction of the housing 10.

When one end of the flow guide piece 50 abuts against the air inlet end 121 of the air outlet pipe 12, the length of the flow guide piece 50 in the length direction is larger than the inner diameter of an air flow inlet of the air inlet end 121 of the air outlet pipe 12, the flow guide piece 50 can receive condensate from the inside of the air outlet pipe 12 to the maximum extent, and meanwhile, before aerosol enters the air outlet pipe 12, the flow guide piece 50 can be in full contact with the aerosol, so that the condensate entrained in the aerosol is intercepted. It will be appreciated that the greater the dimension of the baffle 50 extending in a direction perpendicular to the axial direction of the outlet tube 12, the more fully the aerosol contacts the baffle 50 before entering the outlet tube 12, and condensate entrained in the aerosol will be trapped by the baffle 50, making it difficult for the aerosol to carry the condensate into the interior of the outlet tube 12. The diversion member 50 serves as a structure for receiving condensate at the bottom end of the outlet pipe 12, and the longer the transverse length of the diversion member 50, the more condensate can be received.

When a part of the flow guide piece 50 longitudinally extends into the inner part of the outlet pipe 12, a part of the surface of the flow guide piece 50 is abutted against the inner wall of the outlet pipe 12, condensate on the inner wall of the outlet pipe 12 can flow to the flow guide piece 50, and meanwhile, the flow guide piece 50 extending into the inner cavity of the outlet pipe 12 can be fully contacted with the condensate in the outlet pipe 12, so that more condensate can be guided to the atomizing component 20.

A liquid absorbing part 51 is further provided on the surface of the flow guide 50, and the liquid absorbing part 51 includes an uneven surface structure, for example, a capillary groove capable of absorbing the condensate, a smooth bump structure capable of adsorbing the condensate, and the like. In some embodiments, the wicking portion 51 is disposed on as much of the surface of the baffle 50 as possible to promote more condensate adhesion to the baffle 50. In some embodiments, a wicking portion 51 is provided on both sides of the flow guide 50, the wicking portion 51 having a thickness of a larger size than other portions of the flow guide 50. Therefore, the condensate flows along the inner wall of the outlet tube 12 toward the liquid suction part 51 on both sides of the guide 50 to be received by the liquid suction part 51. Further, a liquid absorbing structure, such as a capillary groove or a protrusion, may be disposed on the inner wall of the outlet tube 12, and the condensate inside the outlet tube 12 may be preferentially adsorbed on the liquid absorbing structure. The liquid adsorbed on the inner wall of the outlet pipe 12 further flows toward the guide 50. In some embodiments, a plurality of baffles 50 may be disposed at the inlet end of outlet 12 or inside outlet 12 to increase the contact area of condensate with baffles 50. When a plurality of sets of flow guiding members 50 are disposed inside the outlet tube 12, the thickness of the flow guiding members 50 is reduced, so that the flow guiding members 50 do not occupy too much space of the outlet tube 12, and the suction resistance of the atomizer 100 is not affected.

To position the baffle 50 in place, the baffle 50 is coupled to the support assembly 30 inside the housing 10. In some embodiments, the flow guide 50 is disposed on or fixed to the upper bracket 31. At least a portion of the upper bracket 31 defines a receiving cavity 313, and the atomizing assembly 20 is fixed inside the receiving cavity 313. The upper support 31 includes a top wall 3131 partially defining a receiving cavity 313, wherein the top wall 3131 is disposed toward the air inlet end 121 of the air outlet pipe 12, and one end of the deflector 50 extends onto the top wall 3131. Condensate received by deflector 50 at inlet end 121 of outlet tube 12 may flow along the surface of deflector 50 toward top wall 3131 and, thus, toward atomization assembly 20. The flow guide piece 50 is positioned at the airflow inlet of the air inlet end 121 of the air outlet pipe 12 and is longitudinally abutted against the inlet end of the air outlet pipe 12, so that the upper support 31 can be matched with the upper support in an auxiliary mode to be installed at a proper position. Deflector 50 can provide longitudinal support to outlet tube 12 when outlet tube 12 is deployed separately from housing 10. The flow guide 50 comprises a first surface 521 and a second surface 522 which are oppositely arranged, aerosol can enter the inlet end of the outlet pipe 12 from one side of the first surface 521 and one side of the second surface 522 respectively, and condensate carried in the aerosol is intercepted by the flow guide 50 and flows back to the atomizing assembly 20 along the surface of the flow guide 50; in some embodiments, aerosol can only enter the inlet end of outlet tube 12 from one side of first surface 521 or second surface 522. In other embodiments, the baffle 50 may be combined with the housing 10 when the relative position of the outlet tube 12 and the reservoir 11 is changed, for example, when the reservoir 11 is only partially disposed around the outlet tube 12, and a portion of the outlet tube 12 is disposed near the side or surface a of the housing 10.

The shape of the flow guide 50 may be designed according to the size of the space allowing the aerosol to pass through, and as shown in fig. 7 and 8, the flow guide 50 has a substantially flat plate shape, and is conveniently designed to be combined with the upper bracket 31. The deflector member 50 may be cylindrical, pyramidal, or truncated cone or spherical. For example, when the flow-directing member 50 is generally conical, it has a flow-directing surface that slopes from the end facing the outlet tube 12 to the end facing the atomizing assembly 20 to facilitate rapid flow of condensate onto the atomizing assembly 20. Alternatively, the baffle member 50 may be of other irregular shapes.

It should be noted that the preferred embodiments of the present application are shown in the specification and the drawings, but the present application is not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and variations can be made in the above description, and all such modifications and variations should be within the scope of the appended claims of the present application.
