The setting of the notch 301 makes the notch directly cooperate with the inner wall of the housing to form an air outlet, which reduces the size of the top cover 300 in the direction of the notch setting, improves the space utilization rate, and makes the structural design of the electronic cigarette assembly Adaptability is stronger. According to an embodiment of the present disclosure, the end surface of the top cover 300 may be in an elongated structure. The direction can be closer to the upper cover 3, while reducing the size of the upper cover 3 and the housing 1 in the first direction, that is, reducing the width of the upper cover 3 and the housing 1, so that the housing 1 Thinner makes the electronic cigarette smaller and more in line with the user's habits.

According to the embodiment of the present disclosure, since the atomization chamber 20 communicates with the air intake channel 22 , the cool air entering the atomization chamber from the air intake channel 22 is in contact with the atomized gas in the atomization chamber 20 . After the sols meet, they can carry the atomized aerosol through the first channel 31 and the second channel 32 of the airflow channel respectively, and the atomized airflow in the first channel 31 and the second channel 32 is mixed and transported to The outlet channel. The extension direction of the first channel 31 and the second channel 32 can be perpendicular to the end face of the upper cover body 30 , and the first channel 31 and the second channel 32 form two sides on both sides of the upper cover body 30 . After opening a channel, the airflow pressure of the atomized aerosol can be balanced to ensure the flow stability of the atomized aerosol, so that the user can inhale it.

According to an embodiment of the present disclosure, referring to FIG. 10 and FIG. 13 , the upper cover body 30 has a saddle-shaped structure 34 , the atomizing core assembly is fixed on the bottom side of the saddle-shaped structure 34 , and the first channel 31 and the second channel 32 are distributed on both sides of the saddle-shaped structure 34 along the first direction S.

According to the embodiment of the present disclosure, since the atomization cavity 20 is formed between the atomization surface of the atomization core assembly and the lower base 2, the atomization cavity 20 communicates with the air outlet through the airflow channel, The atomizing chamber 20 communicates with the air intake channel 22 . The bottom surface of the saddle-shaped structure 34 may have an installation groove, and the atomizing core assembly is fixedly installed in the installation groove, and the installation groove is located on a side of the saddle-shaped structure 34 close to the atomization chamber 20 . The atomized aerosol formed by heating and atomizing on the atomizing surface of the atomizing core assembly can pass through the first channel 31 and the second channel 32 respectively and then be mixed and transported to the air outlet channel. On the basis of the stability of the assembly, the smooth flow of the atomized aerosol is improved through the first channel 31 and the second channel 32 .

According to an embodiment of the present disclosure, at least part of the first channel 31 is opposite to the opening end of the notch 301; the side of the top cover 300 opposite to the opening end of the notch 301 has a top wall, and the At least part of the second channel 32 is opposite the top wall.

Specifically, referring to FIG. 10 to FIG. 15, when at least part of the first passage 31 is opposite to the opening end of the notch 301, the atomized airflow passing through the first passage 31 can directly enter into the airflow passage through the airflow passage. Air outlet passage; and when at least part of the second passage 32 is opposite to the top wall, the top wall can block the atomized air flow from the second passage 32 so that the direction of the atomized air flow in the second passage 32 changes, and then merges with the airflow in the first channel 31 and then enters the outlet channel.

It is further explained that when the e-liquid in the atomization chamber 20 is atomized, the setting of the first channel 31 can make the large particle aerosol atomized in the atomization chamber 20 flow directly into the The air outlet channel greatly reduces the suction resistance of the electronic cigarette, that is, reduces the resistance when the user smokes the electronic cigarette, and the large-particle aerosol can increase the saturation of the atomized airflow and restore the suction of the e-cigarette. mouthfeel to improve the smoking experience of the electronic cigarette; and the draw resistance of the electronic cigarette can be flexibly adjusted through the area of the first channel 31 opposite to the outlet channel, such as by adjusting the width of both sides of the upper cover 3 Relative to the width of the air outlet channel in the casing 1, the draw resistance of the electronic cigarette is adjusted. While the part of the second passage 32 is opposite to the top wall, when the e-liquid in the atomization chamber 20 is atomized, the large particle aerosol atomized in the atomization chamber 20 passes through the first The second channel 32 then collides with the top wall, causing the large particles of smoke oil aerosol to become small particles of smoke oil aerosol, and finally enters the air outlet channel of the housing 1 with a curved flow trajectory. The flow velocity of the collided atomized aerosol is significantly reduced, which can also reduce the condensation of the atomized aerosol and reduce the suction resistance of the electronic cigarette atomization component.

According to an embodiment of the present disclosure, referring to FIG. 4 , the air outlet channel includes a first cavity 11 close to the upper cover 3 and a second cavity 12 close to the suction nozzle part of the housing 1 , the first The section of the cavity 11 is larger than the section of the second cavity 12 .

Specifically, the outlet flow direction of the air outlet channel can be the direction indicated by the arrow in Figure 4, and the cross section of the first cavity 11 and the second cavity 12 can be perpendicular to the outlet flow direction of the air outlet channel section. After the atomizing core assembly heats and atomizes the liquid in the liquid storage bin 10, the large-particle aerosol formed by the heating and atomization first enters the first cavity 11 after passing through the airflow channel. The cross-sectional size of the first cavity 11 can match the cross-sectional size of the airflow channel, so that the atomized aerosol passing through the airflow channel can directly enter the first cavity 11 . When the cross section of the first cavity 11 is larger than the cross section of the second cavity 12, that is, the first cavity 11 with a large volume space is formed on the air inlet side of the housing 1, which can reduce atomization. The flow rate of the aerosol reduces the condensation of the atomized aerosol, and satisfies the user's suction experience while adjusting the suction resistance of the electronic cigarette atomization components.

Specifically, the above-mentioned open-shaped structure of the notch 301 can be understood as forming an opening in the top cover 300 , and the opening extends to the edge of the top cover 300 . The setting of the notch 301 can facilitate the delivery of the liquid in the liquid storage bin 10 to the air outlet channel after atomization, and can reduce the size of the upper cover 3 in the first direction on the other hand. When the size of the opening of the notch 301 is larger, the degree of size reduction of the upper cover 3 in the first direction can be increased. The section of the notch 301 is a section perpendicular to the flow of the atomized aerosol, and when the section of the notch 301 is one of the above-mentioned open shapes, the larger opening of the notch 301 can be used to ensure that the upper cover 3 Effective reduction in size in the first direction.

In addition, when the e-liquid in the atomization chamber 20 is atomized, the large-particle aerosol atomized in the atomization chamber 20 collides with the top wall after passing through the second passage 32, resulting in large-particle smoke The oil aerosol turns into small particles of smoke oil aerosol, and finally enters the air outlet channel of the housing 1 with a curved flow trajectory. After the e-liquid aerosol of large and small particles merges into the large-volume space of the outlet channel, the flow rate of the aerosol decreases, and at the same time reduces the draw resistance of the electronic cigarette; and the e-liquid aerosol with mixed large and small particles can further improve The user's puffing taste improves the user's experience of using electronic cigarettes. In addition, after the diameter of the second channel 32 gradually increases along the flow direction of the atomized airflow, the airflow rate of the small particle aerosol can be weakened, so as to avoid the impact of the large airflow on the user when inhaling.
