Description

Technical Field

[0001] The present application relates to the technical field of smokers' products, and in particular to an electronic cigarette with a single atomization core that can realize single-to-double-shot conversion. Background Art

[0002] The utility model patent with announcement number CN220360110U records a dual heating wire and an electronic cigarette containing the same. The dual heating includes two heating wires arranged up and down. Both heating wires are mesh structures. A positive pin is provided at one end of the mesh structure and a negative pin is provided at the other end. The two heating wires share one negative pin, and the resistance of the two heating wires is different.

[0003] As the e-cigarette adopts the above structure, the liquid level of the e-liquid will gradually decrease as the e-liquid in the oil storage chamber is consumed. After the e-cigarette has been used for a certain period of time, the liquid level of the e-liquid will even be lower than the heating wire at the top. When the two heating wires are working at the same time, the heating wire at the top will have local high temperature during operation due to insufficient oil supply, resulting in inconsistent e-liquid atomization temperature, affecting the taste of the e-cigarette.

[0004] There are also electronic cigarettes with dual atomization cores on the market, such as the one recorded in the announcement number CN115813026B, which include a cigarette rod. In this solution, a lithium battery, a circuit board, a fixing plate, a first atomization core and a second atomization core are arranged in the oil storage bin in the cigarette rod. Specifically, the first atomization core and the second atomization core are arranged side by side in the oil storage bin and are symmetrically distributed on the left and right.

[0005] When the electronic cigarette adopting the above structure is in use, the two atomizer cores are arranged in parallel. When the two atomizer cores are working at the same time, the oil storage cotton in the oil storage bin needs to supply oil to the two atomizer cores at the same time. Because the side of the two atomizer cores close to each other consumes the tobacco oil faster, it is easy for the oil supply speed of the side of the two atomizer cores close to each other to be relatively slow, causing local high temperature on the side of the two atomizer cores close to each other, resulting in inconsistent tobacco oil atomization temperature, affecting the taste of the electronic cigarette. Summary of the invention

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an electronic cigarette with a single atomizer core to achieve single-double-fire conversion, and the technical solutions adopted include:

[0007] The invention discloses an electronic cigarette with a single atomization core that realizes single-to-double-fire conversion, comprising a shell, an atomization channel and a circuit board arranged in the shell.

One end of the two heating wires is connected to the same end of one pin, and the other ends of the two heating wires are respectively connected to the same end of the other two pins. The other ends of the three pins are respectively passed through the atomization channel and then electrically connected to the circuit board. The circuit board is used to enable one of the two heating wires to work alone or both to work simultaneously.

[0025] Reference Figure 1-2 , an embodiment of the present application is proposed. In this embodiment, a single atomization core 30 realizes single-double-shot conversion of an electronic cigarette, including a shell 10, an atomization channel 20, and a circuit board (not shown in the figure) arranged in the shell 10. The atomization core 30 is arranged in the atomization channel 20. The heating component of the atomization core 30 includes two heating wires 31 and three pins 32. One end of the two heating wires 31 is connected to the same end of a pin 32, and the other ends of the two heating wires 31 are respectively connected to the same ends of the remaining two pins 32. The other ends of the three pins 32 pass through the atomization channel 20 and are electrically connected to the circuit board. The circuit board is used to make one of the two heating wires 31 work alone or both work simultaneously.

[0026] Two driving circuits are provided on the circuit board, and the two driving circuits are electrically connected to the two heating wires 31 respectively. The circuit board can drive one of the two heating wires 31 to work alone or simultaneously through the two driving circuits.

[0027] In this embodiment, the housing 10 is provided with an oil storage chamber and an electrical chamber arranged below the oil storage chamber, the atomization channel 20 is arranged in the oil storage chamber and communicates with the inside of the oil storage chamber through the oil inlet hole, the oil storage chamber is also provided with oil storage cotton for storing tobacco oil and wrapping the atomization channel 20, the circuit board is arranged in the electrical chamber, and the other ends of the three pins 32 pass through the atomization channel 20 and are electrically connected to the circuit board. The above structure is only used as an example of the electronic cigarette in this application, and does not constitute a limitation on the specific structure of the electronic cigarette in this application.

[0028] In the shell 10 of this embodiment, only one atomization channel 20 and one atomization core 30 need to be provided, and one atomization core 30 can be assembled in the atomization channel 20, which is the same as the structure and assembly steps of the single-shot electronic cigarette in the prior art. Compared with the electronic cigarette with double atomization cores 30 recorded in the announcement number CN115813026B, the structure is simpler and the assembly is more convenient.

[0029] Since the two heating wires 31 are connected to the same end of a pin 32, the two heating wires 31 are at the same horizontal height in the atomization channel 20. When the circuit board drives the two heating wires 31 to work simultaneously, the two heating wires 31 will not have the problem of different oil supply due to the lowering of the liquid level of the tobacco oil in the oil storage chamber, thereby avoiding dry burning caused by insufficient oil supply to the upper heating wire 31, so that the two heating wires 31 can atomize the tobacco oil at the same temperature when working simultaneously, thereby ensuring the taste of the electronic cigarette.

[0030] Compared with the electronic cigarette with dual atomization cores 30 recorded in the announcement number CN115813026B, the oil supply speed of the oil storage chamber to the two heating wires 31 in one atomization channel 20 is consistent, thereby avoiding the problem of local high temperature affecting the taste due to inconsistent oil supply speed of the oil storage chamber to the two sides of the atomization channel 20.

[0031] As shown in the accompanying drawings, preferably, the two heating wires 31 are both located in the atomization channel 20 near the bottom thereof, so that the two heating wires 31 can be supplied with oil even after the oil level in the oil storage chamber is lowered.

[0032] Specifically, the two heating wires 31 are both arc-shaped, and the two heating wires 31 are arranged in sequence along the circumference of the atomization channel 20, so that the oil storage chamber can supply oil to the two heating wires 31 more evenly, ensuring that the temperature of the two heating wires 31 for atomizing the tobacco oil is consistent and thus ensuring the taste of the electronic cigarette.

[0033] The resistance values ​​of the two heating wires 31 may be the same or different, and the resistance values ​​of the two heating wires 31 are not specifically limited in this embodiment.

[0034] In this embodiment, a mouthpiece 40 is provided at the upper end of the housing 10 , and a mist outlet channel 41 is provided on the mouthpiece 40 . The mist outlet channel 41 is connected to the upper end of the atomization channel 20 , and the shape of the mist outlet channel 41 matches that of the atomization channel 20 .

[0035] The smoke oil produced after the smoke oil is atomized escapes through the mist outlet channel 41. The mist outlet channel 41 of the present application only needs to be connected to one atomization channel 20. Compared with the electronic cigarette with dual atomization cores 30 recorded in the patent document with announcement number CN115813026B, the width of the mist outlet channel 41 does not need to be set to be connected to the width of two atomization channels 20. The shape of the mist outlet channel 41 can be directly matched with one atomization channel 20, so that the smoke in the atomization channel 20 enters the mist outlet channel 41 without expanding and diluting due to the increase in the cross-sectional area of ​​the channel, so as to ensure the concentration of the smoke before flowing into the user's mouth and ensure the taste of the electronic cigarette.

[0036] Specifically, the mist outlet channel 41 includes a first channel 411 and a second channel 412. The first channel 411 is arranged below the second channel 412 and is connected thereto. The second channel 412 is connected to the outside. The first channel 411 matches the shape of the atomization channel 20, and the shape of the second channel 412 is a trumpet shape with an inner diameter gradually increasing from bottom to top.

[0037] When the user holds the mouthpiece 40 in his mouth while using the electronic cigarette, it is only necessary to ensure that the user's mouth can cover the second channel 412, and the smoke flows into the first channel 411 and then flows into the user's mouth through the second channel 412 to ensure the concentration of the smoke before it flows into the user's mouth. The second channel 412 is in a trumpet shape that increases from bottom to top, so that the smoke can diffuse when it flows into the user's mouth from the second channel 412, thereby ensuring the oral explosion rate.

[0038] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
