[0010] The atomizer has multiple, one-to-one installations in the inner cavities of multiple smoke guide tubes. In any one of the passages, there are multiple coaxial oil inlets that are all connected to the passage and are connected to the passage. The direction of the coaxial oil inlets is offset from that of the ribs.
[0011] Furthermore, the mouthpiece is provided with multiple plug rods, each plug rod being paired with a specific oil filling hole. The plug rods can enter the oil filling hole and form a structure that seals the oil filling hole.

Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

The tail end of the battery unit 4 is an end cap with a charging port for connecting to an adapter for charging.
[0042] The atomizing part 3 includes an oil cup 32, a sealing cap 31, a sealing seat 35, a smoke guide tube 34, and an atomizer 33.
[0043] Oil cup 32 has multiple through cavities extending through both ends of the oil cup, and each cavity is independently configured, such as... Figure 1 As shown, there are two passage cavities, and the corresponding sealing seat 35, smoke guide tube 34 and atomizer 33 are all set to two.
[0044] Multiple raised ribs 321 are provided along the length of the inner wall of the cavity. When it is necessary to refill the e-cigarette, the mouthpiece 1 is opened, and the plug rod 11 of the mouthpiece 1 is disengaged from the oil filling hole 311. The oil filling tool is aligned with the oil filling hole 311, and the liquid is injected into the cavity of the oil cup 32 through the oil filling hole 311. During the oil filling process, some of the liquid flows along the ribs 321 on the inner wall of the cavity of the oil cup 32. The ribs 321 disperse the impact force of the liquid and guide the liquid movement, making the liquid more balanced and reducing the flow rate sloshing. After the oil filling is completed, the mouthpiece 1 is closed, and the plug rod 11 enters the oil filling hole 311 and forms a sealing structure to prevent liquid leakage and the entry of external impurities.
[0045] The outer side of the oil cup 32 is also provided with a wire groove, which guides the negative terminal of the power supply to the mouthpiece part 1 and connects it with the metal of the mouthpiece part 1. The suction part of the mouthpiece part 1 is made of metal.
[0046] A sealing cap 31 is attached to the first end of the oil cup 32 and blocks the first opening of each of the passage cavities to form a sealing structure. The sealing cap 31 is provided with a plurality of oil injection holes 311, and the plurality of oil injection holes 311 are configured one-to-one with each passage cavity. The sealing cap 31 is a silicone rubber cap, which has good sealing performance.
[0047] Multiple sealing seats 35 are provided, and each sealing seat 35 is provided in a one-to-one manner at the second opening of each of the through cavities to form a sealing structure. The sealing seat 35 is a silicone rubber seat, and the sealing seat 35 is connected to the terminal seat of the battery part 4, and the terminal seat is fastened to the oil cup 32.
[0048] A smoke guide tube 34 is provided, and each smoke guide tube 34 is configured one-to-one with each passage cavity. The smoke guide tube 34 is provided with a smoke passage, one end of which is positioned at the sealing seat 35, and the other end passes through the sealing cover 31 and connects the smoke passage with the smoke duct of the mouthpiece part 1.
[0049] The atomizer 33 is provided with multiple atomizers installed in one-to-one with the inner cavities of multiple smoke guide tubes 34. In any one of the passages, the atomizer 33 and the smoke guide tube 34 are provided with multiple coaxial oil inlets that are all connected to the passage.

[0050] The mouthpiece part 1 is provided with multiple plug rods 11, each plug rod 11 is set one-to-one with each oil filling hole 311, and the plug rod 11 can enter the oil filling hole 311 and form a structure to seal the oil filling hole 311.
[0051] When a user uses the electronic cigarette, the battery unit 4 provides power to the atomizer 33, and the atomizer 33 begins to operate. Liquid in the oil cup 32 enters the smoke guide tube 34 through a coaxial oil inlet communicating with the cavity, and then reaches the atomizer. The atomizer 33 atomizes the liquid into vapor, which enters the smoke passage of the mouthpiece 1 through the smoke passage in the smoke guide tube and is finally inhaled by the user.
[0052] The inner wall of the oil injection hole 311 is provided with a plurality of first protrusions 312. The function of the first protrusions 312 is to enhance the sealing ability and prevent oil leakage.
[0053] The smoke guide tube 34 is an integral structure with two straight tubes, one large and one small, connected by a tapered tube. The end of the larger straight tube is positioned at the sealing seat 35, and multiple coaxial oil inlet holes are arranged in an array around the larger straight tube. The smaller straight tube and the tapered tube form a smoke passage, through which the vapor formed by the atomizer 33 atomizes the e-liquid enters the mouthpiece.
[0054] The coaxial oil inlet includes a first oil inlet 341 provided in the smoke guide tube 34 and a second oil inlet 331 provided in the atomizer 33, wherein the first oil inlet 341 and the second oil inlet 331 are coaxially arranged.
[0055] The sealing seat 35 is provided with a positioning hole 351 for positioning the smoke guide tube 34, and a plurality of second protruding rings 352 are provided on the inner wall of the positioning hole 351. A sealing structure is formed between the outer wall of the smoke guide tube 34 and the second protruding rings 352 to prevent oil leakage.
[0056] The sealing seat 35 has a concave surface on the side facing the cavity.
[0057] The structure of the concave surface is an inclined concave surface formed by the opening of the positioning hole 351 as the bottom end and the opening of the positioning hole 351 to the edge of the concave surface. Example 2:
[0058] The following is the e-liquid balance principle of this electronic cigarette:
[0059] The working principle of this invention is based on the application of liquid flow characteristics and mechanical principles. The ribs 321 on the inner wall of the oil cup 32 are designed and distributed according to the principle of liquid inertia. When liquid is injected into the oil cup 32, the ribs 321 change the direction and speed of liquid movement, disperse the impact force of liquid at multiple angles, make the force on the liquid in the oil cup 32 more uniform, and maintain flow velocity balance.
[0060] During the filling process, the impact force of the liquid is absorbed and dispersed by the ribs 321, reducing the impact on the atomizer core and optimizing the force distribution during filling. At the same time, due to the function of the ribs 321, the flow of liquid in the oil cup 32 is more stable, reducing oil leakage caused by flow sloshing.
[0061] During the use of electronic cigarettes, the staggered arrangement of the coaxial oil inlet and the ribs ensures that the liquid can enter the atomizer 33 evenly and stably.
[0062] The stable flow of liquid within the oil cup 32 and the uniformity of oil intake ensure that the atomizer 33 can continuously and stably atomize the liquid into vapor, thereby providing users with an electronic cigarette product that has a good taste and stable performance.
[0063] In summary, the electronic cigarette of this invention can mitigate the impact of filling: the multiple raised ribs on the inner wall of the oil cup can effectively disperse the impact force of the liquid during filling, change the movement trajectory of the liquid, alleviate the direct impact of the liquid on the atomizer core, reduce the risk of damage to the atomizer core caused by impact, and extend the service life of the electronic cigarette.
[0064] This invention optimizes the force distribution and reduces oil leakage in electronic cigarettes: the ribs are designed based on the principle of liquid inertia, arranged primarily at annular angles, which improves the force balance of liquid flow rate. When liquid is injected into the oil cup, the ribs reduce external buffering and absorb energy at multiple angles, ensuring that the liquid in the oil cup maintains a balanced flow rate under external force and in a static state, thereby reducing oil flow sloshing and effectively reducing the possibility of oil leakage.
[0065] This invention improves the flavor and user experience of electronic cigarettes by refining the oil cup structure to achieve balanced oil filling and flow rate, ensuring a stable supply of liquid during atomization and resulting in more complete atomization, thus enhancing the flavor. Simultaneously, it meets the diverse needs of users in different usage scenarios, providing a better user experience.
[0066] This invention relates to an electronic cigarette with excellent sealing performance: the sealing cap is made of silicone rubber, and the sealing seat is also made of silicone rubber. Utilizing the excellent elasticity and sealing properties of silicone rubber, liquid leakage and vapor overflow are effectively prevented. The first raised ring on the inner wall of the filling hole and the second raised ring on the inner wall of the positioning hole of the sealing seat further enhance the sealing effect, ensuring the safety and reliability of the electronic cigarette during use.
[0067] This utility model of electronic cigarette features a reasonable oil inlet design: multiple coaxial oil inlet holes are set between the atomizer and the smoke guide tube, and the direction of the oil inlet holes is offset from that of the ribs, which can make the liquid enter the atomizer evenly and stably, ensuring the smooth atomization process, while avoiding the problem of liquid accumulation or poor flow in the oil cup.
[0068] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
