[0002] As a new tobacco product, heat-not-burn e-cigarettes have great development potential. Currently, many countries and regions are stepping up their efforts to develop and promote heat-not-burn e-cigarettes. They are favored by more and more consumers in the market, and users have higher and higher requirements for their appearance and smoke quality.

[0003] Electronic cigarettes usually include a cartridge and a rod. The cartridge is installed on the rod and can generate smoke that is inhaled by the human body. The cartridge is provided with an oil storage tank, an airway, an atomization chamber and an atomization core. The oil storage tank is provided with oil for generating smoke. The oil enters the atomization chamber through the atomization core and is atomized into an aerosol. At the same time, air also enters the atomization chamber. The intake air and the aerosol are mixed and inhaled by the user through the airway. In the prior art, since the aerosol and the intake air are often not mixed evenly, the user either inhales smoke with a high concentration of aerosol and high temperature, or inhales air with a low concentration of aerosol and low temperature, which reduces the user's smoking experience.

The inner diameter of the avoidance hole 106 can be slightly larger than the outer diameter of the first conductive nail 60 and the second conductive nail 70, so as to facilitate the passage of the first conductive nail 60 and the second conductive nail 70.

[0119] The ventilation holes 104, positioning holes 105, avoidance holes 106 and other through holes on the flue gas mixing device 100 can be punched on a plate, and the U-shaped structure of the flue gas mixing device 100 can also be formed by punching a plate.

The first conductive nail 60 is arranged in the first mounting groove 55 of the lower cover 50, and the second conductive nail 70 is arranged in the second mounting groove 56 of the lower cover 50. Taking the first conductive nail 60 as an example, Fig.15 As shown, the first conductive nail 60 includes a connecting piece 61 and a connecting column 62, the connecting piece 61 and the connecting column 62 are electrically connected, the connecting piece 61 has a larger area for external electrical connection, and the connecting column 62 extends into the atomization chamber 140 and is electrically connected to the ceramic abutting piece and the heating circuit of the atomization core 80, thereby guiding the electrical energy to the atomization core 80. The first conductive nail 60 and the second conductive nail 70 can be made of copper alloy, which has excellent conductivity.

[0151] In one embodiment, if Fig.16 , Fig.17 , Fig.18 As shown, the electronic smoking device also includes:

[0152] A first sealing member 20, which is disposed between the upper cover 30 and the oil storage bin 13 and is used to seal the gap between the upper cover 30 and the oil storage bin 13;

[0153] The first sealing member 20 is provided with a ventilation valve 22, and the upper cover 30 is provided with a ventilation channel 33. The ventilation valve 22 connects the oil storage bin 13 with the ventilation channel 33, and the ventilation channel 33 connects the smoke mixing chamber. The first sealing member 20 can be made of rubber material.

[0154] The smoke oil in the oil storage bin 13 needs to be output to the smoke mixing chamber for atomization, and air needs to be added to balance the internal pressure. However, the oil storage bin 13 cannot be arbitrarily provided with air holes, which may easily cause oil leakage. Therefore, a ventilation valve 22 is provided at the bottom of the oil storage bin 13 (the top of the main body 21 of the first sealing member 20). When the smoke oil in the oil storage bin 13 is reduced, the ventilation valve 22 adds air to the oil storage bin 13 to balance the internal pressure of the oil storage bin 13.

[0155] A through hole 25 is also provided on the top of the main body 21 of the first sealing member 20 . The through hole 25 is used for passing the first air guide column 32 of the upper cover 30 and for the atomizer core 80 to communicate with the oil storage tank 13 .

[0156] The upper cover 30 includes a body 31 , and a ventilation channel 33 extends from the side wall of the body 31 to the top of the body 31 . The ventilation channel 33 penetrates the body 31 at the side wall and communicates with the air inlet cavity 130 , so air can flow from the ventilation channel 33 to the ventilation valve 22 .

[0157] In one embodiment, if Fig.16 , Fig.17 As shown, the ventilation valve 22 includes:

[0158] The spring sheet 24 can be changed between straight and curved;

[0159] The ventilation port 23 , the spring piece 24 is arranged at the ventilation port 23 , when the oil storage tank 13 is under negative pressure, the spring piece 24 opens the ventilation port 23 , when the oil storage tank 13 is under positive pressure, the spring piece 24 closes the ventilation port 23 .

[0160] When the air exchange valve 22 is opened, the spring piece 24 bends toward the oil storage tank 13 , and when the air exchange valve 22 is closed, the spring piece 24 returns to a straight or nearly straight state.

[0161] As smoke is generated, the smoke oil is gradually adsorbed by the atomizer core 80 to the side of the atomizing surface 83, and the air pressure on the side of the oil storage bin 13 drops, forming a negative pressure. The air pressure on one side of the atomization chamber 140 is higher, and the air will pass through the air inlet 52 of the lower cover 50, and then through the ventilation channel 33 of the upper cover 30 to push open the spring piece 24 of the ventilation valve 22, and enter the oil storage bin 13 to achieve air pressure balance. After the air pressure of the atomization chamber 140 and the oil storage bin 13 is balanced, the spring piece 24 of the ventilation valve 22 fits tightly against the upper cover 30, thereby sealing the ventilation channel 33 and preventing the smoke oil in the oil storage bin 13 from leaking from the ventilation channel 33 of the upper cover 30. By setting the ventilation valve 22, the atomization core 80 can adsorb sufficient smoke oil to maintain the smoke generation effect.

[0162] In one embodiment, if Fig.18 , Fig.19 , Fig. 20 , Fig.21As shown, the upper cover 30 is provided with a first air guide column 32, and the first end of the first air guide column 32 is connected to the air outlet cavity 150;

[0163] A second air guide column 12 is disposed inside the housing 10 . A first end of the second air guide column 12 is communicated with a second end of the first air guide column 32 , and a second end of the second air guide column 12 is communicated with the cigarette holder 11 .

[0164] The inner diameter of the second end of the first air guide column 32 is equal to or greater than the outer diameter of the first end of the second air guide column 12, and the first end of the second air guide column 12 can be plugged with the second end of the first air guide column 32. The air flow channel 16 is actually composed of the internal channel of the first air guide column 32 and the internal channel of the second air guide column 12.

[0165] Nearly the entire body of the first air guide column 32 extends into the oil storage bin 13, and nearly the entire body of the second air guide column 12 extends into the oil storage bin 13, so the connection position between the two needs to be sealed.

[0166] In one embodiment, if Fig. 22 As shown, the electronic smoking device also includes:

[0167] The second sealing member 110 is disposed between the second end of the first air guiding column 32 and the first end of the second air guiding column 12, and is used to seal the gap at the connection between the first air guiding column 32 and the second air guiding column 12 to prevent the smoke oil from leaking therefrom.

[0168] The second sealing member 110 includes a body 111, which is annular and is provided with an assembly groove 112. The second end of the first air guide column 32 is inserted into the assembly groove 112. The inner ring side wall of the body 111 is provided with multiple circles of sealing ribs 113. The first end of the second air guide column 12 is inserted into the inner ring of the body 111, thereby forming a sealing structure. The second sealing member 110 can be made of rubber material.

[0169] In one embodiment, if Fig.23 As shown, the electronic smoking device also includes:

[0170] The third sealing member 90 is disposed between the atomizer core 80 and the upper cover 30, and is used to seal the gap between the atomizer core 80 and the upper cover 30 to prevent the smoke oil from leaking outward from the gap between the atomizer core 80 and the upper cover 30. The third sealing member 90 is in the shape of a rectangular groove, and its shape is adapted to the atomizer core 80, and can be mounted on the atomizer core 80. A through hole is provided on the top of the third sealing member 90 to allow the smoke oil to pass through, and the third sealing member 90 is also installed in the installation groove 34 of the upper cover 30. The third sealing member 90 can be made of rubber material.

[0171] refer to Figure 2As shown, when the user inhales, the sensor in the electronic cigarette device is triggered, and a signal is sent to drive the atomizer core 80 to start heating, and the smoke oil is heated and atomized in the atomization surface 83, and the air passes through the mesh vents at the air inlet end of the "U"-shaped mesh part (smoke mixing device 100) from the air inlet hole 52 of the lower cover 50. After that, the air and the atomized smoke oil are blocked by the mesh vents at the air outlet end of the "U"-shaped mesh part, so that the air and the atomized smoke oil are fully mixed, and then enter the first air guide column 32 of the upper cover 30, flow into the second air guide column 12 of the shell 10, and finally enter the user's mouth.

[0172] As smoke is generated, the smoke oil is gradually adsorbed by the atomizer core 80 to the side of the atomizing surface 83, and the air pressure on the side of the oil storage bin 13 drops, forming a negative pressure. The air pressure on the side of the smoke mixing chamber is higher, and the air will pass through the third air guide column 53 of the lower cover 50, and then through the ventilation channel 33 of the upper cover 30 to push open the spring piece 24 of the ventilation valve 22, and flow to the oil storage bin 13, achieving air pressure balance, and allowing the atomizer core 80 to adsorb sufficient smoke oil to maintain the smoke generation effect. After the air pressure of the smoke mixing chamber and the oil storage bin is balanced, the spring piece 24 of the ventilation valve 22 is tightly attached to the upper cover 30, thereby sealing the ventilation channel 33 to prevent the smoke oil in the oil storage bin 13 from leaking from the ventilation channel 33.

[0173] The utility model provides a smoke mixing device and an electronic smoking device, which have the following characteristics:

[0174] The smoke mixing device is provided with a porous side panel structure, which can fully mix the aerosol generated by atomization with the intake air, mixing it into smoke with uniform concentration and suitable temperature, which is then inhaled by the user, so that the atomized smoke has a good throat hit feeling when entering the user's mouth without irritation, ensuring a good user experience of the electronic cigarette device.

[0175] The external inlet of the air inlet passage of the electronic cigarette device is arranged away from the middle of the lower cover, which breaks away from the limitation that the air inlet hole is usually arranged in the middle of the lower cover of general electronic cigarette devices, and facilitates the stacking and assembly of various structures of the electronic cigarette device.

[0176] The air inlet of the lower cover is on one side of the ceramic atomizer core, and the air outlet channel of the outer shell is on the other side of the ceramic atomizer core.
