DETAILED DESCRIPTION

[0024] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes on different embodiments, which do not deviate from the scope of the present application, and the description and drawings in the essence are used as a description, not to limit the present application.

[0025] As shown in Figure 1 An oil guide device with exhaust structure, the device includes an oil guide pipe 191 and an oil guide plug 192 arranged in the oil guide pipe 191. One end of the oil guide pipe 191 is inserted into the oil reservoir and communicates with the oil reservoir, and the other end is inserted into the oil bottle 17 and communicates with the oil bottle 17. The part of the oil guide pipe 191 in the oil reservoir is provided with a plurality of exhaust holes 1911, and the surface of the oil guide plug 192 is provided with a plurality of oil film breaking ribs 1921.

[0026] The plurality of oil film breaking ribs 1921 are equidistantly distributed. In this way, the tobacco oil can be uniformly entered into the oil guide pipe 191.

[0027] The number of oil film breaking ribs 1921 is four.

[0028] One end of the oil guide plug 192 in the oil reservoir is provided with a plug head 1922. In a natural posture, the plug head 1922 is plugged into one end of the oil guide pipe 191, or enters the oil guide pipe to plug the oil guide pipe. When the posture is reversed, the plug head 1922 is separated from one end of the oil guide pipe 191, so that the tobacco oil in the oil guide pipe 191 enters the oil reservoir. Among them, if the oil reservoir is not connected with the oil bottle 17, the plug head 1922 can prevent the tobacco oil in the oil reservoir from leaking to a certain extent.

[0029] In another embodiment, as Figures 2-6As shown, an electronic cigarette is illustrated. The electronic cigarette includes the device as described in the above embodiment. The e-liquid bottle of the electronic cigarette is located below the e-liquid tank. The e-liquid tank includes a housing 11. An e-liquid storage cotton 12 and an atomizing core assembly 13 are disposed inside the housing 11. The atomizing core assembly 13 passes through the housing 11 and communicates with a mouthpiece 14 located above the housing 11. One or more pressure relief holes 111 are provided at the top of the housing 11. A buffer pad 15 is provided between the housing 11 and the mouthpiece 14. One or more exhaust grooves 151 are provided on the buffer pad 15, which cooperate with the pressure relief holes 111. The pressure relief holes 111 are connected to the mouthpiece 14 through the exhaust grooves 151.

[0030] The electronic cigarette includes a body assembly 200 and a cartridge assembly 100. The cartridge assembly 100 includes an oil bottle 17, an oil tank, and a mouthpiece 14. The body assembly 200 includes a circuit board and a battery. The body assembly 200 and the cartridge assembly 100 are detachably connected. The cartridge assembly 100 is provided with a spring pin 18 that is electrically connected to the atomizing core assembly 13. The body assembly 200 is provided with contacts that are electrically connected to the circuit board and the battery. When the body assembly 200 and the cartridge assembly 100 are connected, the spring pin 18 contacts the contacts.

[0031] Additionally, an absorbent cotton 16 is provided between the buffer pad 15 and the mouthpiece 14. Based on the absorbent cotton 16, it can absorb any slight spillage of e-liquid when gas is expelled through the pressure relief hole 111. An inlet nozzle 112 for connecting the e-liquid bottle 17 is provided at the bottom of the e-liquid tank.

[0032] Working principle:

[0033] When the e-cigarette is being wicked, the e-liquid inside the bottle flows into the wicking tube along the ribs between the wicking plugs, and then flows out from the exhaust port or from the outlet of the wicking tube into the e-liquid tank.

[0034] When inhaling an electronic cigarette, an airflow sensor located inside or outside the e-liquid tank senses the inhalation action and transmits it to the circuit board. The circuit board controls the contacts to be energized, and the energizer is conducted through the spring pin 18 to the atomizer core assembly 13. The atomizer core assembly 13 heats the e-liquid in the e-liquid tank to produce vapor, which is then drawn out from the mouthpiece 14.

[0035] When there is excess gas inside the oil tank, it is discharged along multiple pressure relief holes 111 and converges into the mouthpiece 14 through the corresponding exhaust channels 151. Since the mouthpiece 14 is connected to the outside, the excess gas is discharged from the mouthpiece 14. Similarly, when there is a low pressure in the oil tank, the external gas flows into the oil tank along the mouthpiece 14 and the exhaust channels 151.

[0036] Beneficial effects:

[0037] Based on the setting of the oil guide device, the exhaust hole 1911 can play a role in enhancing exhaust, reducing air pressure difference to a certain extent, and making oil guiding smooth; based on the setting of the oil guide plug 192, the oil film can be pierced or prevented from forming, so that the oil guiding is smooth; based on the presence of the oil film breaking rib 1921, the formation of the oil film is further avoided, and can play a positioning role, so that the tobacco tar enters the oil warehouse more uniformly.

[0038] While the disclosure has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Since the disclosure can be embodied in various forms without departing from the spirit or essential characteristics thereof, it is understood that the embodiments disclosed are not to be limited to any particular details but are to be accorded the full scope of the appended claims, and equivalents thereof.
