Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and specifically to an electronic cigarette that avoids oil leakage through a pressure relief groove. Background Technology

[0002] Many e-cigarettes feature a detachable e-liquid bottle and atomizer assembly; e-liquid is replenished by replacing the bottle. During the process of changing the bottle and inserting the refiller, air inside the atomizer is forced into the atomizer by the e-liquid. If the pressure inside the atomizer cannot be adjusted, some of the introduced e-liquid will leak out due to the increased pressure, resulting in e-liquid leakage. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an electronic cigarette that avoids oil leakage by means of a pressure relief groove, thereby preventing oil leakage of the atomizing component due to assembly with the oil bottle.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is:

[0005] The electronic cigarette includes an oil bottle and an atomizing component; the atomizing component is provided with an oil guide tube; the atomizing component is connected to the oil bottle through the oil guide tube; the atomizing component also includes an oil reservoir; the oil reservoir forms a central channel communicating with the atomizing channel of the electronic cigarette; an atomizing core is placed inside the oil reservoir; the atomizing core is connected to the central channel, and a sealing silicone is provided between the atomizing core and the inner wall of the oil reservoir; the atomizing core is covered with an oil-collecting cotton; one end of the oil guide tube is inserted into the oil-collecting cotton in the oil reservoir; a pressure relief groove is formed inside the oil reservoir, connecting the oil-collecting cotton to the central channel.

[0006] The pressure relief groove is provided along the inner wall of the oil reservoir in contact with the sealing silicone.

[0007] The pressure relief grooves are located below the central channel and are arranged symmetrically along the circumference in two places.

[0008] This invention, through the design of a pressure relief groove, ensures that the pressure within the oil reservoir of the atomizing component remains balanced during the connection and filling process with the oil bottle. By adjusting the pressure balance, it avoids oil leakage caused by negative pressure. Attached Figure Description

[0013] The following embodiments are descriptions of specific implementations of this application. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of this utility model. All equivalent modifications that can be obtained from the description of the embodiments of this utility model are within the protection scope of this utility model.

[0014] like Figure 1 , 2 As shown in Figures 1 and 3, the electronic cigarette of this utility model includes an oil bottle 1 and an atomizing component 2; the atomizing component 2 is provided with an oil guide tube 21; the atomizing component 2 is connected to the oil bottle 1 through the oil guide tube 21.

[0015] The atomizing assembly 2 also includes an oil reservoir 22; the oil reservoir 22 forms a central channel 221 that communicates with the electronic cigarette atomization channel. An atomizing core 23 is disposed inside the oil reservoir 22; the atomizing core 23 is connected to the central channel 221. A sealing silicone 24 is disposed between the atomizing core 23 and the inner wall of the oil reservoir 22; the atomizing core 22 is covered with an oil-collecting cotton 25; one end of the oil guide tube 21 is inserted into the oil-collecting cotton 25 of the oil reservoir 22.

[0016] Furthermore, a pressure relief groove 222 is formed inside the oil reservoir 22, connecting the oil-retaining cotton to the central channel. Two pressure relief grooves 222 are located below the central channel 221, along the inner wall of the oil reservoir 22 where it contacts the sealing silicone 24, and are arranged symmetrically in a circular pattern. Therefore, a pressure relief channel is formed from the oil-retaining cotton 25 to the central channel 221; during the oil filling process of the atomizing component 2, the internal and external air pressure balance can be adjusted to prevent oil leakage.

[0017] The structure of the remaining parts of the electronic cigarette of this utility model is shown in the figure. The structure of the remaining parts of the electronic cigarette is unrelated to the implementation of the aforementioned scheme; it will not be described in detail here.
