DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a cigarette rod 100, please refer to Figure 1 and Figure 2 , comprising a mouthpiece 10, a smoke oil atomizer 11, a flow limiting sheet 12, a cotton oil storage 13 and a shell 20. A sealed smoke oil chamber 21 is provided in the shell 20, the cotton oil storage 13 and the flow limiting sheet 12 are sleeved on the bottom of the smoke oil chamber 21 of the smoke oil atomizer 11, the flow limiting sheet 12 is arranged above the cotton oil storage 13, a flow limiting hole 121 is provided on the flow limiting sheet 12, the mouthpiece 10 is connected to the shell 20, and the mouthpiece 10 is communicated with the airway of the smoke oil atomizer 11. When the user adds the smoke oil into the smoke oil chamber 21, the smoke oil first enters the oil storage cotton 13 through the flow limiting hole 121 on the flow limiting sheet 12. The flow limiting sheet 12 reduces the impact force of the smoke oil entering the oil storage cotton 13 and the smoke oil atomizer 11. The setting of the flow limiting hole 121 reduces the flow rate of the oil infiltrating into the oil storage cotton 13, preventing the smoke oil from entering the oil storage cotton 13 too quickly, preventing the smoke oil that has not yet been vaporized from being inhaled by the smoker, and blocking more smoke oil in the smoke oil chamber 21 outside the flow limiting sheet 12, thereby improving the product experience. The oil storage cotton 13 continues to absorb the smoke oil into the cotton. When the smoker inhales through the cigarette holder 10, the smoke oil enters the smoke oil atomizer 11 through the oil inlet for vaporization. The smoke oil on the oil storage cotton 13 is consumed and replenished at the same time, preventing the smoke oil atomizer 11 from burning dry, resulting in burning the core, and preventing the smoke oil in the oil storage cotton 13 from being in an oversaturated state, thereby reducing the risk of oil leakage in the electronic cigarette 200. Preferably, the current limiting plate 12 is a 304 food grade stainless steel plate to prevent the current limiting plate 12 from rusting due to chemical reactions with moisture and air in the smoke oil chamber 21 .

[0025] In one embodiment, the smoke oil atomizer 11 is provided with an oil inlet, and the oil storage cotton 13 is sleeved on the oil inlet. The smoke oil in the smoke oil atomizer 11 is continuously vaporized and sucked out from the cigarette holder 10, resulting in less and less smoke oil in the smoke oil atomizer 11. It is necessary to continuously suck a certain amount of smoke oil from the oil storage cotton 13 to prevent the smoke oil that has not yet been vaporized from escaping from the cigarette holder 10, so as to fully vaporize the smoke oil into smoke for the user to inhale. For further information, please refer to Figure 1The flue in the mouthpiece 10 is funnel-shaped, and the cross section of the mouthpiece 10 perpendicular to the overall flow direction of the smoke oil inside it is funnel-shaped. The cross-sectional area of ​​the funnel gradually increases along the flow direction of the gaseous smoke oil, so that the user can inhale the same volume of gaseous smoke oil with a smaller suction force, thereby improving the comfort of using the cigarette rod 100. Furthermore, the smoke oil atomizer 11 is provided with an annular groove on the mating surface with the mouthpiece 10, and the annular groove is used to install the sealing ring 30. The mouthpiece 10 and the smoke oil atomizer 11 are tightly connected through the sealing ring 30, which improves the sealing between the mouthpiece 10 and the smoke oil atomizer 11, so that the smoke is only sucked out from the smoke oil atomizer 11, preventing the unvaporized smoke oil in the smoke oil chamber 21 from entering the mouthpiece 10 and being sucked by the user, thereby reducing the taste of the smoke.

[0026] In another embodiment, the cigarette rod 100 of the present application further includes a battery 40, the housing 20 is provided with a power supply installation cavity below the smoke oil cavity 21, the battery 40 is installed in the power supply installation cavity, the smoke oil atomizer 11 is electrically connected to the battery 40, and the battery 40 provides power for the smoke oil atomizer 11, so that the cigarette rod 100 can be wireless, so that the user can carry it and use it anytime and anywhere. Preferably, the battery 40 is a rechargeable battery 40. Further, the cigarette rod 100 also includes a sealing silicone 50, one end of the sealing silicone 50 is connected to the bottom end of the smoke oil atomizer 11, and the other end is in contact with the battery 40. When the cigarette rod 100 is hit, the sealing silicone 50 can absorb a certain vibration, protect the battery 40 and the smoke oil atomizer 11, avoid internal vibration displacement, and cause oil leakage, and the sealing silicone 50 prevents the smoke oil in the smoke oil cavity from leaking into the power supply installation cavity, avoiding the waste of smoke oil and improving the user's product experience, and improving the market competitiveness of the product.

[0027] In order to limit the positions of the flow-limiting plate 12 and the oil-storing cotton 13 in the smoke-oil chamber 21 and prevent the flow-limiting plate 12 and the oil-storing cotton 13 from shaking in the smoke-oil chamber 21 and sliding in the smoke-oil atomizer 11, the smoke-oil atomizer 11 is provided with a limiting convex rib on the contact surface with the flow-limiting plate 12, so that the oil-storing cotton 13 is fixed on the outer side of the oil inlet, and the flow-limiting plate 12 is fixed above the oil-storing cotton 13. Among them, the flow-limiting holes 121 are arranged at intervals around the smoke-oil atomizer 11, so that the smoke on the flow-limiting plate 12 flows evenly into various positions in the oil-storing cotton 13, so as to provide the smoke oil to the smoke-oil atomizer 11.

[0028] This application also proposes an electronic cigarette 200, see Figure 1 , Figure 2 and Figure 3, including the above-mentioned cigarette rod 100 and the cigarette oil rod 201, the cigarette oil rod 201 is connected to the cigarette rod 100. The housing 20 is provided with a cigarette oil adding port 22 connected to the cigarette oil chamber 21. The cigarette oil rod 201 includes a cigarette oil storage chamber 202 and an air pressure balance channel 203, the cigarette oil storage chamber 202 is connected to the cigarette oil adding port 22, when the user sucks less cigarette oil from the cigarette holder 10, the user tilts the electronic cigarette 200 to one side of the cigarette rod 100, and the cigarette oil in the cigarette oil rod 201 flows into the cigarette oil chamber 21 of the cigarette rod 100 through the cigarette oil adding port 22. When the cigarette oil rod 201 adds cigarette oil to the cigarette oil chamber 21, the cigarette oil adding port 22 is used to provide a channel for the cigarette oil in the cigarette oil storage chamber 202 to flow into the cigarette oil chamber 21, and the air pressure balance channel 203 performs gas-liquid volume exchange between the cigarette oil chamber 21 and the cigarette oil storage chamber 202 to prevent the cigarette oil from being in a stopped state under a negative pressure state. The current limiting sheet 12 in the cigarette rod 100 prevents the smoke oil from entering the oil storage cotton 13 too quickly, preventing the smoke oil that has not yet been vaporized from being inhaled by the smoker, and blocking more smoke oil in the smoke oil chamber 21 outside the current limiting sheet 12, thereby improving the product experience. The oil storage cotton 13 continues to absorb the smoke oil into the cotton. When the smoker inhales through the cigarette holder 10, the smoke oil enters the smoke oil atomizer 11 through the oil inlet for vaporization. The smoke oil on the oil storage cotton 13 is consumed and replenished at the same time, preventing the smoke oil atomizer 11 from burning dry, causing the core to burn, and preventing the smoke oil in the oil storage cotton 13 from being in an oversaturated state, reducing the risk of oil leakage in the electronic cigarette 200. In addition, the electronic cigarette 200 also includes an air inlet. When the user smokes the cigarette holder 10, the external gas enters the electronic cigarette 200 through the air inlet, flows through the gap between the battery 40 and the shell 20, the sealing silica gel 50, and the smoke oil atomizer 11 in sequence, and is finally inhaled by the user from the cigarette holder 10.
