DETAILED DESCRIPTION

[0021] 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.

[0022] This application proposes a smoke oil refill rod that can prevent smoke oil from flowing back. Figure 1 , including a gravity stop valve 10, an air pressure stabilizing airway 20 and a shell 30. The smoke oil replenishing device prevents the smoke oil in the electronic cigarette 60 from flowing back into the smoke oil replenishing device through the gravity stop valve 10, and the air pressure stabilizing airway 20 adjusts the air pressure balance in the electronic cigarette 60 and the smoke oil chamber 31. The shell 30 is provided with a receiving chamber and a smoke oil chamber 31, and the smoke oil chamber 31 is a sealed chamber. The gravity stop valve 10 and the air pressure stabilizing airway 20 are arranged in the receiving chamber, and the shell 30 is provided with an air inlet 32 ​​and an oil outlet 33. The air inlet 32 ​​is connected to the smoke oil chamber 31 through the air pressure stabilizing airway 20, and the oil outlet 33 is connected to the smoke oil chamber 31 through the gravity stop valve 10. The gravity stop valve 10 includes a stop weight 11 and a stop shell 12. A stop chamber is provided in the stop shell 12. The stop weight 11 is movably provided in the stop chamber. One end of the stop chamber is connected to the oil outlet 33, and the other end is provided with an oil inlet 34. The stop weight 11 opens or closes the oil inlet 34 due to its own weight, so that the oil in the oil chamber 31 can flow smoothly and unidirectionally from the oil chamber 31 through the stop chamber and the oil outlet 33 to the electronic cigarette 60 for smokers to inhale, and prevents the oil from flowing backward from the electronic cigarette 60 through the gravity stop valve 10 to the oil chamber 31, so as to ensure that smokers have sufficient oil to inhale and avoid burning the core due to lack of oil in the electronic cigarette 60. The electronic cigarette 60 is mainly composed of a mouthpiece, a smoke oil atomizer, a battery, etc. The mouthpiece is connected to the smoke oil atomizer to form a flue. The smoke oil atomizer atomizes the oil in the electronic cigarette into smoke, which is guided out through the mouthpiece for users to inhale. The battery is electrically connected to the smoke oil atomizer to provide electrical energy to the smoke oil atomizer.

[0023] Please note that Figure 1The smoke oil replenishing device is installed on the electronic cigarette 60, and the oil outlet 33 and the air inlet 32 ​​are connected to the smoke oil storage chamber in the electronic cigarette 60, so that the smoke oil in the smoke oil chamber 31 can be replenished into the smoke oil storage chamber, and the gas-liquid exchange between the smoke oil chamber 31 and the smoke oil storage chamber is realized. Moreover, when placed vertically, the stop weight 11 blocks the oil inlet 34 due to its vertical downward gravity, and the inner wall of the oil inlet 34 is affected by the gravity of the stop weight 11, which generates a supporting force on the stop weight 11. At this time, the stop weight 11 and the oil inlet 34 block the smoke oil in the smoke oil chamber 31, and the stop weight 11 can prevent the smoke oil from flowing back. When the smoker tilts to a sufficient angle toward the side where the oil outlet 33 is set, the stop-flow weight 11 rolls, and the oil inlet 34 is not under the stop-flow weight 11, and the oil inlet 34 for the smoke oil to flow into the stop-flow chamber is opened, so that the smoke oil flows from the oil inlet 34 through the stop-flow chamber and the oil outlet 33 in sequence, and finally the smoke oil flows from the oil outlet 33 into the electronic cigarette 60.

[0024] In one embodiment, the stop weight 11 can move in the stop cavity, and the diameter of the stop weight 11 is larger than the diameter of the oil outlet 33, so that the stop weight 11 is limited in the stop cavity to prevent the stop weight 11 from rolling from the oil outlet 33 and causing a malfunction. The diameter of the stop weight 11 is larger than the diameter of the oil inlet 34 to prevent the stop weight 11 from getting stuck in the oil inlet 34. No matter how the user tilts, the stop weight 11 cannot move, and the e-cigarette 60 cannot be replenished with e-liquid, which causes another malfunction. Furthermore, the stop shell 12 is funnel-shaped on the side abutting against the smoke oil chamber 31, and the diameter of the abutting surface gradually decreases from top to bottom. When the smoker tilts the smoke oil replenishing device, the smoke oil in the smoke oil chamber 31 gathers on the abutting side between the stop shell 12 and the smoke oil chamber 31, and the funnel-shaped side is filled with smoke oil. After the oil inlet 34 is opened, the smoke oil slowly flows from the oil inlet 34 into the smoke oil storage chamber of the electronic cigarette 60, so that the smoke oil is replenished into the electronic cigarette 60 more efficiently. Furthermore, the gravity stop valve 10 and the air pressure stabilizing airway 20 are arranged above the smoke oil chamber 31. If the gravity stop valve 10 is arranged below the smoke oil chamber 31, the stop weight 11 is prevented from being affected by buoyancy, so that the gravity of the stop weight 11 is equal to the buoyancy it receives or the buoyancy it receives is greater than or equal to the gravity. In addition, since the smoke oil storage chamber in the electronic cigarette 60 and the smoke oil chamber 31 in the smoke oil replenishing device are essentially communicating vessels, under the effect of the principle of communicating vessels, the smoke oil liquid levels in the smoke oil chamber 31 and the smoke oil storage chamber in the electronic cigarette 60 are consistent in height, so that the smoke oil in the smoke oil replenishing device cannot be completely used up, and the smoke oil replenishment effect on the electronic cigarette 60 is poor. Furthermore, the housing 30 is provided with a small hole 35 at the connection between the air pressure stabilizing airway 20 and the smoke oil chamber 31, and the aperture of the small hole 35 is smaller than the aperture of the air pressure stabilizing airway 20. Since the aperture of the small hole 35 is small, the gas in the electronic cigarette 60 and the smoke oil in the smoke oil chamber 31 are exchanged slowly, so that the replenishment of the smoke oil in the electronic cigarette 60 is more controllable, and the small hole 35 prevents the smoke oil in the smoke oil chamber 31 from being led out of the air pressure stabilizing airway 20, thereby improving the reliability of the product. Preferably, the diameter of the oil outlet 33 is larger than the diameter of the air inlet 32.

[0025] In another embodiment, see Figure 1The housing 30 includes a first housing 36 and a second housing 37, and the first housing 36 and the second housing 37 are snap-fitted to facilitate assembly of the gravity check valve 10 inside the housing 30. The air inlet 32 ​​is adjacent to the oil outlet 33, and the air inlet 32 ​​is arranged above the oil outlet 33. When the smoker uses the oil refilling device to refill the electronic cigarette 60 with oil, the oil flowing out of the oil outlet 33 is prevented from entering the air inlet 32, so that the air inlet 32 ​​cannot pass gas, and further, in order to maintain the air pressure balance in the oil chamber 31 and the oil storage chamber, the oil in the oil chamber 31 cannot flow into the electronic cigarette 60, and the air inlet 32 ​​is arranged above the oil outlet 33 to ensure that the oil in the oil refilling device can be smoothly refilled into the electronic cigarette 60. In addition, a second sealing ring 50 is provided at the air inlet 32 ​​and the oil outlet 33. The second sealing ring 50 makes the smoke oil refilling device and the electronic cigarette 60 tightly connected to avoid leakage at the connection between the smoke oil refilling device and the electronic cigarette 60, thereby improving the quality of the product. Similarly, a first sealing ring 40 is provided on the mating surface of the first shell 36 and the second shell 37 to avoid leakage at the mating point of the first shell 36 and the second shell 37, thereby reducing the user experience.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
