Referring to fig. 1 and 2, an embodiment of the present application provides an electronic atomizer 1000, where the electronic atomizer 1000 includes a housing 100, an atomizing assembly 200 and a power assembly 300, the power assembly 300 is accommodated in one end of the housing 100, one end of the atomizing assembly 200 is accommodated in the housing 100 and is coupled with the power assembly 300, the other end of the atomizing assembly 200 extends out of the housing 100, and the atomizing assembly 200 can heat an atomizing medium under the action of electric energy of the power assembly 300, so as to generate aerosol for a user to inhale.

The heating element 240 is accommodated in the atomizing chamber 221, and the heating element 240 can absorb and heat the atomizing medium to generate aerosol. The lower seat assembly 250 is coupled to the side of the atomizing upper seat 220 provided with the atomizing chamber 221, the liquid absorbing member 260 is installed in one end of the lower seat assembly 250 far away from the atomizing upper seat 220, and the clamping shell 270 is sleeved outside one end of the lower seat assembly 250 far away from the atomizing upper seat 220. One end of the electrode 280 passes through the lower seat assembly 250 to be abutted against the heating element 240, the other end of the electrode 280 is electrically connected to the power assembly 300, and the power assembly 300 supplies current to the heating element 240 through the electrode 280.

Specifically, the atomizing upper base 220 has a hollow shell-like structure, including an upper base top wall and an upper base side wall circumferentially surrounding the upper base top wall. The atomizing chamber 221 is located at the bottom of one side of the atomizing upper base 220 away from the upper base top wall, and penetrates the atomizing upper base 220 in the width direction of the atomizing upper base 220. The atomizing upper base 220 is further provided with a switching groove 222 and an air outlet communication hole 223, the switching groove 222 is positioned at one side of the atomizing cavity 221 close to the upper base top wall, and the switching groove 222 penetrates through the atomizing upper base 220 in the width direction of the atomizing upper base 220. The air outlet communication hole 223 is formed at the center of the upper seat top wall and is located at one side of the adapting groove 222 away from the atomizing chamber 221, and the air outlet channel 212 of the suction nozzle 210 is inserted into the air outlet communication hole 223 to be communicated with the air outlet communication hole 223. The top wall of the upper seat is also provided with two upper seat lower liquid ports 224, the two upper seat lower liquid ports 224 are arranged at intervals in the length direction of the atomization upper seat 220 and are respectively positioned at two opposite sides of the air outlet communication hole 223, one end of the upper seat lower liquid port 224 is communicated with the liquid storage cavity 214, and the other end of the upper seat lower liquid port 224 is communicated with the atomization cavity 221.

Further, as shown in fig. 6, the atomizing upper base 220 is further provided with a main air passage 225 and an auxiliary air passage 226, which are independent from each other. The main air passage 225 is formed on the side wall of the upper seat and extends along the height direction of the atomizing upper seat 220, one end of the main air passage 225 is communicated with the switching groove 222, and the other end is communicated with the atomizing cavity 221. In the length direction of the atomizing upper base 220, the auxiliary air passage 226 is located at one side of the main air passage 225, one end of the auxiliary air passage 226 is communicated with the switching groove 222 and extends along the length direction of the atomizing upper base 220, and the other end of the auxiliary air passage 226 is communicated with the bottom of the atomizing chamber 221 and extends along the height direction of the atomizing upper base 220.

In the sucking process, the atomized medium in the liquid storage cavity 214 flows into the liquid storage cavity 214 through the upper seat lower liquid port 224 to infiltrate the heating element 240, and after the aerosol generated by the heating element 240 which cannot be atomized flows out of the atomizing cavity 221, the aerosol can enter the exhaust channel 212 through the main air channel 225 and the switching air channel. Since the aerosol cannot be completely sucked out by the user, a small portion of the aerosol will flow back into the atomization upper seat 220 after the suction is finished, and contact with the atomization upper seat 220 to form condensate. Since the atomization upper base 220 is provided with the main air passage 225 and the auxiliary air passage 226, the back-flowing aerosol can flow to the bottom of the atomization upper base 220 through the auxiliary air flow, thereby preventing a large amount of condensate from blocking the main air passage 225.

Specifically, in some embodiments, the atomizing upper seat 220 includes two main air passages 225 and two auxiliary air passages 226, the two main air passages 225 are respectively located at opposite sides of the atomizing upper seat 220 in the width direction of the atomizing upper seat 220, the two auxiliary air passages 226 are respectively located at opposite sides of the atomizing upper seat 220, and the two auxiliary air passages 226 are respectively located at opposite ends of the atomizing upper seat 220 in the length direction of the atomizing upper seat 220. In this way, the air flow generated by the heating element 240 can enter the exhaust passage 212 through the two main air passages 225, and the returned aerosol can enter the bottom of the atomizing chamber 221 through the two auxiliary air passages 226. It will be appreciated that the number of primary and secondary air passages 225, 226 is not so limited and may be set as desired to meet various requirements.

As shown in fig. 3, 4, 6 and 7, the upper seat seal 230 has a shell-like structure formed of a material having a certain elasticity such as silica gel, and the upper seat seal 230 covers one end of the atomizing upper seat 220 provided with the air outlet communication hole 223, and includes an upper seat seal top wall and an upper seat seal side wall formed by extending from an edge of the upper seat seal top wall in the same direction, and the upper seat seal side wall circumferentially surrounds the upper seat seal top wall. The upper seat sealing member top wall covers the upper seat top wall of the atomization upper seat 220, and an upper seat sealing member communication hole 232 correspondingly communicated with the upper seat lower liquid port 224 is formed in the upper seat sealing member top wall, and the upper seat sealing member communication hole 232 is communicated with the upper seat liquid inlet 224 and the liquid storage cavity 214, so that atomized medium in the liquid storage cavity 214 can enter the upper seat liquid inlet 224 through the upper seat sealing member communication hole 232. The upper seat seal 230 is configured to be an interference fit with the sidewall of the mouthpiece 210, thereby closing the gap between the mouthpiece 210 and the atomizing upper seat 220, preventing leakage of the atomizing medium from the gap therebetween.

In some embodiments, to enhance the sealing effect of the upper seat seal 230, the outer surface of the upper seat seal 230 is provided with a sealing bead 234, and the sealing bead 234 is configured to abut against the inner sidewall of the suction nozzle 210 to form an interference fit with the suction nozzle 210. However, during the assembly of the atomizing assembly 200, the inventors have found that the sealing bead 234 is squeezed against the sidewall of the nozzle 210, which results in deformation of the sealing bead 234 and failure of the seal. To solve the above problem, the atomizing upper base 220 is convexly provided with a supporting column 227, and the supporting column 227 is supported below the sealing rib 234. So, in the assembly process, support column 227 can play the supporting role to sealed protruding muscle 234, prevents that sealed protruding muscle 234 from taking place deformation, and then prevents sealed inefficacy, effectively avoids atomizing medium to leak.

Specifically, in some embodiments, the upper seat seal 230 is provided with two sealing ribs 234, the two sealing ribs 234 being spaced apart along the thickness direction of the upper seat seal 230, each sealing rib 234 circumferentially surrounding the atomizing upper seat 220. The upper seat sealing member 230 is convexly provided with two support columns 227, the two support columns 227 are respectively positioned at the upper side edges of the two adapting grooves 222, each support column 227 extends lengthwise along the length direction of the upper seat, and in the width direction of the atomizing upper seat 220, the two support columns 227 are respectively positioned at two opposite sides of the atomizing upper seat 220. Thus, the two sides of the lower seal bead 234 are supported on one support column 227.

As a preferred embodiment, the edge of the upper seat sealing member 230 is provided with supporting grooves 236 below the sealing ribs 234, the number and shape of the supporting grooves 236 are corresponding to those of the supporting columns 227, and the supporting columns 227 are embedded in the supporting grooves 236, so as to play a limiting role.

With continued reference to fig. 3 to 6, the heating element 240 has a cubic structure and is formed of a high-temperature resistant porous material such as porous ceramic. The side of the heating element 240 facing away from the liquid storage cavity 214 forms a heating surface, which can generate heat under the action of the electric energy of the power supply assembly 300 to heat the atomized medium in the atomized heating element 240. It will be appreciated that the shape of the heater 240 and the material forming the heater 240 are not limited and may be set as desired to meet different atomization requirements.

The lower seat assembly 250 is coupled to one side of the atomizing upper seat 220, where the atomizing cavity 221 is provided, the liquid absorbing member 260 is installed in one end of the lower seat assembly 250, which is far away from the atomizing upper seat 220, the lower seat assembly 250 is provided with a lower seat channel which communicates the atomizing cavity 221 and the liquid absorbing member 260, and the lower seat channel extends in a meandering manner.

In this way, the aerosol remained on the heating element 240 flows out of the atomizing assembly 200 through the lower seat channel, and the lower seat channel is tortuous and extends, so that the aerosol can be blocked to avoid the aerosol from smoothly flowing out of the atomizing assembly 200 and entering the power supply assembly 300, and the condensate generated in the lower seat channel can be fully absorbed by the liquid absorbing member 260, so that the condensate is locked at the bottom of the atomizing assembly 200 to avoid the condensate from flowing into the power supply assembly 300, and finally the service life of the electronic atomizer 1000 is prolonged.

Referring to fig. 8 and 9, the lower seat assembly 250 includes an atomizing lower seat 252 and a lower seat seal 254. The atomization lower seat 252 is coupled to one side of the atomization upper seat 220 provided with the atomization cavity 221, the atomization lower seat 252 has a shell-shaped structure, and comprises a lower seat bottom wall and a lower seat side wall surrounding the lower seat bottom wall along the circumferential direction, and a clamping hook for clamping the atomization upper seat 220 is arranged on the lower seat side wall. Five lower air holes 2521 and a lower seat communication hole 2523 are formed in the bottom wall of the lower seat, one lower air hole 2521 is formed in the center point of the atomization lower seat 252, the other four lower air holes 2521 are circumferentially distributed around the center point at intervals, the lower seat communication hole 2523 is located at one side of the lower air hole 2521 facing the liquid absorbing piece 260, one end of the lower seat communication hole 2523 is communicated with the lower air hole 2521, and the other end of the lower seat communication hole 2523 faces the liquid absorbing piece 260.

Further, a seal limiting portion 2524 surrounding the lower air hole 2521 is protruding from a bottom wall of the lower seat toward one side of the atomizing upper seat 220, the lower seat seal 254 is mounted on one side of the atomizing lower seat 252 toward the heating body 240, the lower seat comprises a first lower seat sealing portion 2541 and a second lower seat sealing portion 2543, the first lower seat sealing portion 2541 circumferentially surrounds the outside of the lower seat side wall, the second lower seat sealing portion 2543 is supported on the seal limiting portion 2524 and is arranged at intervals with the lower air hole 2521, two lower seat seal communication holes 2543a which are arranged at intervals are formed in the second lower seat sealing portion 2543, and a central axis of each lower seat seal communication hole 2543a is parallel to a central axis of any lower air hole 2521 and is arranged at intervals. In this way, the lower vent 2521 is offset from the lower seat seal communication hole 2543a, and the lower vent 2521 and the lower seat seal communication hole 2543a together form a tortuous extended lower seat channel.

In some embodiments, the lower air hole 2521 is spaced apart from the lower seat seal communication hole 2543a in an extending direction of the central axis of the lower seat seal communication hole 2543a, thereby functioning as a further barrier to aerosol.

The edge of the side of the lower base bottom wall facing the liquid absorbing element 260 is convexly provided with a liquid absorbing element limiting part 2525, the liquid absorbing element 260 is of a sheet structure formed by porous materials with adsorption effects of organic cotton and the like, the liquid absorbing element 260 is arranged in one end of the atomization lower base 252 far away from the atomization upper base 220, and the edge of the liquid absorbing element 260 is propped against the liquid absorbing element limiting part 2525, so that a gap communicated with the lower base communication hole 2523 is formed between the lower base bottom wall and the liquid absorbing element 260, and the aerosol can be further blocked.

In the atomizing lower base 252, the aerosol flowing out of the heat generating surface of the heat generating body 240 first passes through the two lower base seal communication holes 2543a formed in the lower base seal 254, then is split into five lower air holes 2521 formed in the lower base bottom wall, and finally enters the gap between the liquid absorbing member 260 and the lower base bottom wall through the lower base communication holes 2523.

Referring to fig. 3, 11 and 12, the clamping shell 270 has a shell-shaped structure with an opening at one end, and the clamping shell 270 is sleeved outside the end of the lower seat assembly 250 provided with the liquid absorbing member 260, so as to prevent condensate in the liquid absorbing member 260 from leaking outside. Further, two electrodes 280 are disposed at intervals along the length direction of the atomizing lower base 252, and the two electrodes 280 are respectively inserted into the bottom wall of the lower base and protrude from the lower surface of the bottom wall of the lower base. The clamping shell 270 is provided with two clamping shell communication holes 272, the two clamping shell communication holes 272 are arranged at intervals in the length direction of the clamping shell 270, a first air inlet channel which circumferentially surrounds the electrode 280 is formed between each electrode 280 and the hole wall of the corresponding clamping shell communication hole 272, and gaps among the liquid absorbing piece 260, the electrode 280 and the bottom wall of the lower seat are communicated with the first air inlet channel and the lower air hole 2521.

Because the first air inlet circumferentially surrounds the electrode 280, compared with the air inlet arranged in a straight-through way, the condensate generated in the atomization assembly 200 can be effectively prevented from leaking out while the air flow is allowed to flow into the atomization assembly 200, so that the use experience of a user is improved, and the service life of the electronic atomizer 1000 is prolonged.

Referring to fig. 10 and fig. 12 to 14, further, the liquid absorbing member 260 is provided with two first liquid absorbing member communicating grooves 261 and two second liquid absorbing member communicating grooves 263, the first liquid absorbing member communicating grooves 261 are substantially circular, the two first liquid absorbing member communicating grooves 261 are arranged at intervals along the length direction of the liquid absorbing member 260, a second air inlet channel is formed between the groove wall of each first liquid absorbing member 260 and one electrode 280, and the second air inlet channel circumferentially surrounds the electrode 280 and is communicated with the first air inlet channel. One end of each second liquid sucking member communication groove 263 communicates with one side of the first liquid sucking member communication groove 261 away from the lower air hole 2521, and the other end of the second liquid sucking member communication groove 263 extends in a direction away from the electrode 280 to communicate with a gap between the liquid sucking member 260 and the bottom wall of the lower seat. In this manner, airflow flowing into the first inlet may sequentially pass through the second inlet, the gap between the liquid absorbing member 260 and the bottom wall of the lower seat, and enter the lower air hole 2521.

Further, an electrode mounting post 2527 is protruding from a bottom wall of the lower base toward the cartridge communication hole 272, the electrode 280 is disposed through the electrode mounting post 2527, and the first air inlet channel is formed between the electrode mounting post 2527 and a wall of the first liquid suction member communication groove 261. Electrode mounting post 2527 is inserted into first liquid suction member communication groove 261 toward one side of lower air hole 2521 to isolate the first air inlet passage from lower air hole 2521, so that the air flow flowing into the first air inlet passage does not directly enter lower air hole 2521, but flows into the second air inlet passage, and then enters lower air hole 2521 through the gap between liquid suction member 260 and the bottom wall of the lower seat.
