The pin 404 provides support for the circuit board 600, further fixes the circuit board 600, and prevents the circuit board 600 from shaking or falling off, avoiding the need for the prior art to specially set up a structure for fixing the circuit board 600, making the structure of the electronic cigarette bloated and complicated, and the production process complicated, resulting in increased failure rate, reduced reliability, reduced yield rate, and increased production costs.

[0048] like Figure 3 As shown, in one embodiment, an oil storage cotton 560 is provided inside the oil storage tube 200, and the oil storage cotton 560 can absorb the smoke oil so that the smoke oil is stored in the oil storage tube 200. The heating wire 402 and the high temperature resistant material wrapped around the heating wire 402 are arranged in the oil storage cotton 560 to increase the contact area with the smoke oil on the oil storage cotton 560 and improve the efficiency of heating and atomizing the smoke oil. Exemplarily, the oil storage cotton 560 is made of knitted cotton. In another embodiment, the oil storage cotton 560 is made of medical absorbent cotton.

[0052] Exemplarily, the shape of the portion of the second mounting block 350 that matches the second mounting through hole 204 is configured to adapt to the shape of the second mounting through hole 204. The shape of the second mounting through hole 204 is not limited, and exemplary, the second mounting through hole 204 is circular, and the portion of the second mounting block 350 that matches the second mounting through hole 204 is configured as a cylinder, and the axis of the first flue through hole and the axis of the cylinder are located on the same straight line or on different straight lines.

[0053] like Figure 2 and Figure 3 As shown, in one embodiment, a mounting groove is provided on the end surface of the second mounting block 350 away from the heating wire 402.

Exemplarily, the nozzle cotton 500 is made of knitted cotton. In another embodiment, the nozzle cotton 500 is made of medical absorbent cotton.

[0055] The temperature of the e-liquid after atomization is about 40℃, and the air temperature is generally between 20℃ and 30℃. The e-liquid mist will condense when it encounters the air with a lower temperature. The nozzle cotton 500 can absorb the atomized and condensed e-liquid to prevent the condensed e-liquid from flowing freely and affecting the user experience.

[0056] Exemplarily, the suction nozzle cotton 500 is interference fit with the mounting groove, so that the suction nozzle cotton 500 is fixedly installed in the mounting groove. In another embodiment, the suction nozzle cotton 500 is installed in the mounting groove by gluing. In another embodiment, the edge of the mounting groove is provided with a protrusion to prevent the suction nozzle cotton 500 from sliding out of the mounting groove, and the protrusion can limit the movement of the suction nozzle cotton 500.

[0057] like Figure 3 As shown, in one embodiment, the nozzle cotton 500 has a second flue through hole, so that the nozzle cotton 500 forms a ring structure, and illustratively, the second flue through hole is coaxially arranged with the first flue through hole, that is, the axis of the second flue through hole is located on the same straight line as the axis of the first flue through hole. In another embodiment, the axis of the second flue through hole is located on a different straight line than the axis of the first flue through hole.

[0058] In another embodiment, the second flue hole is omitted from the suction nozzle cotton 500, and the suction nozzle cotton 500 is sealed in the first flue hole. The suction nozzle cotton 500 can filter the smoke oil discharged from the first flue hole.

[0059] like Figure 2 As shown, in one embodiment, an oil-absorbing cotton 550 is provided on the end surface of the circuit board 600 close to the first mounting block 300, and the oil-absorbing cotton 550 is used to absorb the condensed smoke oil; Figure 3 As shown, the oil-absorbing cotton 550 is located in the first buckle groove 302. The pin 404 is penetrated by the oil-absorbing cotton 550, and the movement of the oil-absorbing cotton 550 can be limited by the pin 404. When some users use e-liquid, they will blow air into the electronic cigarette due to mistakes or other factors, and the atomized e-liquid will flow downward. The e-liquid will condense during the downward flow. The oil-absorbing cotton 550 can absorb the condensed e-liquid, and can prevent the condensed e-liquid from gathering into large droplets or liquids that flow randomly, thereby improving the user experience and reducing the failure rate.

[0060] like Figure 4 As shown, the end surface of the circuit board 600 away from the heating wire 402 has an electrode contact point 602, and the circuit board 600 receives external electrical energy through the electrode contact point 602, which is the power receiving terminal.

[0061] Exemplarily, the electrode contact 602 is made of copper. In another embodiment, the electrode contact 602 is made of silver.

[0062] A plug hole 604 is provided on the circuit board 600 , and the pin 404 is fixedly installed at the plug hole 604 .

[0063] Exemplarily, the pin 404 is welded to the socket 604 of the circuit board 600, such as by soldering. In another embodiment, the pin 404 is fixed to the socket 604 of the circuit board 600 by snapping. The manner in which the pin 404 is fixed to the circuit board 600 is not limited here, as long as the pin 404 can be electrically connected to the circuit board 600 and the circuit board 600 can be fixed relative to the pin 404.

[0064] like Figure 2 As shown, in one embodiment, at least two groups of sockets 604 are provided, and the pins 404 are fixedly installed in any group of sockets 604 .

[0066] The pin 404 can be installed in the first hole group, but can also be installed in the second hole group. During assembly, the process step of distinguishing and identifying the direction of the circuit board 600 can be omitted, which can improve production efficiency. Exemplarily, when the pin 404 is installed in the first hole group, the first pin is fixedly installed in the first hole body, and the second pin is installed in the second hole body. When the pin 404 is installed in the second hole group, the first pin is fixedly installed in the third hole body, and the second pin is fixedly installed in the fourth hole body.

[0067] And if Figure 4 As shown, the arrangement line of the electrode contact points 602 and the arrangement line of the plug holes 604 are not located on the same straight line, so that the positions of the two electrode contact points can be closer to each other, saving space on the circuit board 600 and saving production costs.

[0068] like Figures 1 to 3 As shown, the electronic atomization device further includes a housing 100, the housing 100 having a first opening 102, and the oil tank tube 200 is installed in the housing 100 from the first opening 102. Exemplarily, the first installation through hole 202 is closer to the first opening 102 than the second installation through hole 204. Figure 1As shown, the electrode contact points 602 of the circuit board 600 are connected to the external space through the first opening 102, and the external power source is electrically connected to the electrode contact points 602 of the circuit board 600 after passing through the first opening 102. Exemplarily, the housing 100 is a sleeve-shaped structure.

[0069] For example, the material of the housing 100 is not limited. For example, in one embodiment, the housing 100 is made of plastic; in another embodiment, the housing 100 is made of stainless steel. In another embodiment, the housing 100 is made of silicone.

[0070] like Figure 2 As shown, in one embodiment, the first mounting block 300 is snap-fitted with the inner wall of the housing 100 so that the first mounting block 300 and the oil tank pipe 200 are fixed in the housing 100 .

[0071] For example, Figure 2 As shown, a first protrusion is provided on the outer wall of the first mounting block 300, and a first engaging groove engaging with the first protrusion is provided on the inner wall of the housing 100. In another embodiment, a second engaging groove is provided on the outer wall of the first mounting block 300, and a second protrusion engaging with the second engaging groove is provided on the inner wall of the housing 100.

[0072] like Figure 2 As shown, in one embodiment, the housing 100 further has a second opening 104, and the atomized tobacco oil heated by the heating wire 402 is discharged through the second opening 104; the atomized tobacco oil heated by the heating wire 402 flows through the first flue hole and the second flue hole in sequence, and then is discharged from the second opening 104 for the user to inhale.

[0073] The electronic atomization device also includes a mouthpiece cover 700, which is arranged on the second opening 104 to block the second opening 104, effectively preventing the smoke oil from accidentally flowing out of the second opening 104 during smoking and soiling the user's clothes or hands. The mouthpiece cover 700 also plays another important protective role. When the electronic cigarette is in use, the user's mouth will directly contact the outer wall of the second opening 104, which provides a way for external impurities to enter the interior of the electronic atomization device. However, with the existence of the mouthpiece cover 700, these impurities are effectively isolated from the outside, ensuring the cleanliness and safety of the oil tank pipe 200 and other sensitive components inside the electronic atomization device.

[0074] The presence of the mouthpiece cover 700 can also protect the health of the user to a certain extent. Since it can block the entry of external dirt, the user does not have to worry about unnecessary health risks caused by the contamination of the electronic cigarette when smoking. At the same time, it can also protect the part of the second opening 104 that contacts the user's mouth, avoiding contamination of various dirt, bacteria or viruses due to direct contact with the outside world.

[0075] Therefore, the mouthpiece cover 700 is not only a detail in the design of the electronic cigarette, but also an important guarantee for the entire smoking experience and safety. With its simple structure and practical functions, it brings users a more secure and comfortable smoking experience.
