[0028] like Figure 1 and Figure 2 As shown, the present application provides an electronic cigarette with a straight airway, which includes an oil cup shell 100, a base 200, and a heating element 300. A ventilation tube 110 is provided inside the oil cup shell 100, and a gas channel 111 is provided in the ventilation tube 110. The base 200 includes an air outlet 210. The base 200 is provided at one end of the oil cup shell 100 away from the ventilation tube 110, and the base 200 blocks the oil cup shell 100. The air outlet 210 is connected to the gas channel 111. The heating element 300 includes a heating surface 310. The heating element 300 is installed in the base 200, and the heating surface 310 is parallel to and adjacent to the central axis of the gas channel 111.

[0029] In one embodiment, the oil cup housing 100 is a container with an open side. It serves as a protective structure for the e-cigarette and houses other components. Inside, a vent tube 110 is located. The vent tube 110 is hollow and cylindrical, forming a gas channel 111 within the housing. This channel is used to transport aerogel formed by the atomization of air and e-liquid. The line connecting the centers of the two ends of the vent tube 110 defines the central axis of the vent tube 110 and the gas channel 111. A base 200 is embedded in the end of the oil cup housing 100 away from the vent tube 110. The base 200 seals the oil cup housing 100 and supports the other components. An air outlet 210 is located on the side of the base 200 near the vent tube 110. The air outlet 800 is indirectly connected to the gas channel 111 in the vent tube 110, allowing aerogel to enter the gas channel 111 from the base 200 for inhalation by the user. The heating element 300 is a core component of the direct-to-airway electronic cigarette. It is rectangular in shape, with a heating surface 310 on one side. This surface heats the e-liquid to produce aerogel. The heating surface 310 is parallel to and adjacent to the central axis of the gas passage 111. This design allows the aerogel produced by the heating surface 310 to enter the gas passage 111 directly, preventing the aerogel from deviating around the passage.

[0030] In summary, the design of the heating surface 310 being parallel to and adjacent to the central axis of the gas channel 111 allows the aerogel produced by the heating surface 310 to enter the gas channel 111 directly and quickly, improving the concentration and taste of the smoke. Furthermore, this design can reduce the size and weight of the e-cigarette, making it easier to carry and use.

[0031] like Figure 2 As shown, the electronic cigarette with a straight airway further includes an oil sealing sleeve 400 , which is embedded in one end of the oil cup housing 100 close to the base 200 . The oil sealing sleeve 400 separates the interior of the oil cup housing 100 to form an oil storage bin 120 .

[0032] In one embodiment, the oil seal sleeve 400 is a component made of silicone material with excellent sealing properties. The oil seal sleeve 400 is embedded in the end of the oil cup housing 100 near the base 200, forming an oil storage bin 120 between the oil cup housing 100 and the oil seal sleeve 400. The oil storage bin 120 is used to store the e-liquid, and the oil seal sleeve 400 is used to prevent the e-liquid from leaking. It also prevents air from entering the oil storage bin 120 and affecting the quality of the e-liquid.

[0033] In summary, the provision of the oil seal 400 effectively prevents the leakage of the e-liquid, thereby improving the safety and reliability of the electronic cigarette. Furthermore, it also prevents air from entering the oil storage bin 120, thereby maintaining the freshness and quality of the e-liquid.

[0034] like Figure 2 As shown, the oil sealing sleeve 400 is provided with a connecting column 410 , in which a first through hole 411 is provided. One end of the vent pipe 110 close to the oil sealing sleeve 400 is embedded in the first through hole 411 .

[0035] In a specific embodiment, the connecting column 410 is a protruding portion on the oil sealing sleeve 400. The connecting column 410 is in the shape of a hollow cylinder. The hollow portion of the connecting column 410 is a first through hole 411. The diameter of the first through hole 411 matches the diameter of the vent pipe 110. One end of the vent pipe 110 close to the oil sealing sleeve 400 is embedded in the first through hole 411, so that the vent pipe 110 is tightly connected to the oil sealing sleeve 400, thereby ensuring the sealing of the gas channel 111.

[0036] In summary, the arrangement of the connecting column 410 makes the connection between the vent tube 110 and the oil sealing sleeve 400 tighter and more reliable, thereby improving the sealing and stability of the electronic cigarette. The design of the first through hole 411 can ensure that the gas channel 111 is unobstructed.

[0037] like Figure 3 As shown, one end of the connecting column 410 close to the base 200 is embedded in the air outlet 210 , so that the air outlet 210 , the first through hole 411 , and the gas channel 111 are connected.

[0038] In one specific embodiment, the diameter of the connecting post 410 matches the diameter of the air outlet 210. The end of the connecting post 410 closest to the base 200 is embedded in the air outlet 210. This design allows the air outlet 210, the first through hole 411, and the gas channel 111 to form a continuous channel, ensuring smooth gas flow. The air outlet 210 is the channel through which the aerogel is discharged from the base 200. The first through hole 411 is the channel connecting the vent tube 110 and the oil sealing sleeve 400. The gas channel 111 is the main channel for air and aerogel to pass through the straight-through airway of the electronic cigarette. During use, the aerogel passes through the air outlet 210, the first through hole 411, and the gas channel 111 in sequence and is inhaled by the user.

[0039] In summary, the above connection method ensures that the gas channel 111 is unobstructed, improving the efficiency and quality of smoke generation. At the same time, it also makes the structure of the electronic cigarette more compact and stable, reducing the possibility of looseness and leakage between components.

[0040] like Figure 2 and Figure 3 As shown, the oil sealing sleeve 400 is provided with a first through groove 420, which runs through the oil sealing sleeve 400, and the base 200 is provided with a second through groove 220, which is connected to the first through groove 420, and the smoke oil in the oil storage tank 120 enters the second through groove 220 through the first through groove 420.

[0041] In one embodiment, the first through-slot 420 is a passage on the oil sealing sleeve 400. The first through-slot 420 penetrates the oil sealing sleeve 400, allowing the oil in the oil storage tank 120 to enter the second through-slot 220 in the base 200 through the first through-slot 420. Two first through-slots 420 are provided, and the two first through-slots 420 are symmetrically arranged about the connecting post 410. Two second through-slots 220 are also provided, and the two second through-slots 220 correspond one-to-one with the two first through-slots 420. The second through-slots 220 and the first through-slots 420 are connected to form a passage for the circulation of the oil.

[0042] like Figure 3 As shown, the electronic cigarette with a straight airway further includes a heating element fixing seat 500 , which is embedded in the base 200 . The heating element fixing seat 500 is a container with an opening on one side, and the heating element 300 is embedded in the opening of the heating element fixing seat 500 .

[0043] In a specific embodiment, the heating element holder 500 is a component used to fix the heating element 300. Preferably, the heating element holder 500 is made of silicone and is embedded in the base 200 to provide support and protection for the heating element 300. The heating element holder 500 is a rectangular container with an open side. The heating element 300 is embedded in the opening of the heating element holder 500, allowing the heating element 300 to operate stably. At the same time, the heating element 300 blocks the heating element holder 500, forming an atomization chamber in the heating element holder 500.

[0044] In summary, the arrangement of the heating element fixing base 500 can ensure the working stability and reliability of the heating element 300 .

[0045] like Figure 3 As shown, the heating element fixing seat 500 is also provided with an oil inlet hole 510, which is connected to the second through groove 220, so that the tobacco oil in the second through groove 220 can enter the heating element fixing seat 500 through the oil inlet hole 510 and contact the heating element 300.

[0046] In one embodiment, two oil inlet holes 510 are provided, and the two oil inlet holes 510 correspond one-to-one with the two second through-slots 220. The oil inlet holes 510 are connected to the second through-slots 220, and the oil inlet holes 510 are connected to the atomization chamber. When the tobacco oil flows from the oil storage tank 120 through the first through-slots 420 and the second through-slots 220 and enters the heating element holder 500, the oil inlet holes 510 are used to guide the tobacco oil into the atomization chamber inside the heating element holder 500, thereby allowing the tobacco oil in the atomization chamber to come into contact with the heating element 300.

[0047] To sum up, the setting of the oil inlet hole 510 allows the smoke oil to enter the atomization chamber in the heating element fixing seat 500 more smoothly, so that the smoke oil is in full contact with the heating element 300. The design of the oil inlet hole 510 can also control the flow rate and speed of the smoke oil, avoiding too much or too little smoke oil from entering the heating element fixing seat 500, affecting the production effect of aerogel.

[0048] like Figure 4 As shown, the electronic cigarette with a straight airway is further provided with a mouthpiece 600 . The mouthpiece 600 is provided at one end of the ventilation tube 110 away from the base 200 , and the mouthpiece 600 is communicated with the ventilation tube 110 .

[0049] In one embodiment, the mouthpiece 600 is the part that the user touches when inhaling the electronic cigarette. It is located at the end of the vent tube 110 away from the base 200 and is connected to the vent tube 110. The shape and material of the mouthpiece 600 can be designed according to user needs to enhance the user experience. The mouthpiece 600 is typically made of food-grade materials, which are safe and non-toxic, and will not harm the user's health.

[0050] like Figure 4 As shown, the electronic cigarette with a straight airway further includes a sealing ring 700 , and the base 200 is further provided with a mounting groove, in which the sealing ring 700 is located to enhance the sealing effect of the base 200 .

[0051] In one embodiment, the sealing ring 700 is a sealing component, typically made of materials such as rubber or silicone. A mounting groove is provided around the periphery of the base 200. In an electronic cigarette with a direct airway, the sealing ring 700 is located in the mounting groove of the base 200, thereby enhancing the sealing effect of the base 200. When the base 200 is connected to the oil cup housing 100, the sealing ring 700 is compressed, filling the gap between the base 200 and the oil cup housing 100, preventing air and liquid leakage.

[0052] In summary, the provision of the sealing ring 700 effectively improves the sealing effect of the base 200, prevents leakage of air and e-liquid, and improves the safety and reliability of the electronic cigarette.

[0053] A plurality of vent holes 800 are further provided on the base 200 , which connect the external environment with the interior of the electronic cigarette with a straight airway, so as to facilitate air to enter the electronic cigarette with a straight airway.

[0054] like Figure 3 As shown, there are two electrodes 900 , which are spaced apart. The electrodes 900 are fixedly mounted on the base 200 , and the electrodes 200 are electrically connected to the heating element 300 to provide power to the heating element 300 .

[0055] like Figure 5 As shown, the direction of the arrow in the figure is the flow path of air from the vent hole 800 on the base 200 into the interior of the electronic cigarette with a straight airway, and finally out of the mouthpiece 600. Specifically, when the user inhales from the mouthpiece 600, the air enters the interior of the electronic cigarette with a straight airway from the vent hole 800 on the base 200 and flows to the heating element 300, so that the air and the aerogel formed after the atomization of the tobacco oil are mixed to form a mixture. The mixture enters the gas channel 111 in the ventilation tube 110 through the air outlet hole 210 on the base 200 and the first through hole 411 on the oil sealing sleeve 400, and is then inhaled by the user from the mouthpiece 600.

[0056] In summary, the vent hole 800 , the air outlet hole 210 , the first through hole 411 , the gas channel 111 , and the mouthpiece 600 form a complete airflow path of the electronic cigarette with a straight airway.

[0057] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
