The smoke oil atomizer assembly 200 is provided in the housing 100 near the mouthpiece 110 and contains smoke oil for atomizing the smoke oil and guiding the atomized smoke oil to flow toward the outlet 111 of the mouthpiece 110. The control assembly 300 is provided in the housing 100 near the base and is used to start or stop the smoke oil atomizer assembly 200 from atomizing the smoke oil. The bottom cover 120 is provided with a smoke inlet 121. The bottom of the electronic cigarette filter can be connected to a cigarette 400. The smoke from the burning cigarette 400 enters the smoke oil atomizer assembly 200 through the control assembly 300 and is guided thereby to flow toward the outlet 111 of the mouthpiece 110. The electronic cigarette filter has three usage modes: 1. The electronic cigarette filter is used alone without an external cigarette 400. At this time, the control component 300 starts the smoke oil atomization component 200 to atomize the smoke oil therein; 2. The electronic cigarette filter is used alone with an external cigarette 400. At this time, the control component 300 turns off the smoke oil atomization component 200 and does not atomize the smoke oil therein. The external cigarette 400 is ignited to generate smoke, and the smoke enters the shell 100, enters the smoke oil atomization component 200 through the control component 300, and is guided to flow to the outlet 111 of the cigarette holder 110; 3. The electronic cigarette filter is connected to an external cigarette 400, and the smoke oil atomization component 200 is started by the control component 300 to atomize the smoke oil. The smoke generated by the burning cigarette 400 enters the shell 100, enters the smoke oil atomization component 200, mixes with the smoke oil atomized by it, and flows together to the outlet 111 of the cigarette holder 110.

[0037] The control component 300 activates or deactivates the electronic cigarette filter, preheats the e-liquid, and controls the atomization power of the e-liquid to suit different needs of users.

[0038] Specifically, the control assembly 300 includes a cylindrical support 310, a printed circuit board 320, a button 330, and a battery 340. The cylindrical support 310 is disposed within the housing 100, and the printed circuit board 320 is fixedly mounted on the cylindrical wall of the cylindrical support 310 on two opposing sides, thereby leaving sufficient space within the cylindrical support 310 for the passage of smoke generated by the burning cigarette 400. The printed circuit board 320 is electrically connected to the e-liquid atomizer assembly 200 to provide power thereto.

[0039] The battery 340 is located within the housing 100, mounted between the cylindrical bracket 310 and the bottom cover 120, and is electrically connected to the printed circuit board 320 to provide power. A button 330 is located on the housing 100, with pins extending through the cylindrical bracket 310 to electrically connect to the printed circuit board 320. Pressing the button 330 activates or deactivates the circuit between the e-liquid atomizer assembly 200 and the printed circuit board 320, heating or stopping the e-liquid atomization process.

[0040] Furthermore, the housing 100 is provided with a button hole 112, and the button 330 is installed in the button hole 112. The cylindrical bracket 310 is provided with a bracket through-hole 311, and the pin of the button 330 passes through the bracket through-hole 311 to connect to the printed circuit board 320. The button 330 has a power on / off mode, a preheating mode, and a voltage adjustment mode. Different modes are usually set by the number of consecutive presses of the button 330 within a certain period of time. For example, in the shutdown mode, pressing the button 330 five times within two seconds turns the device on or off. In the preheat mode, pressing the button twice within two seconds turns the preheating mode on or off. In the voltage adjustment mode, pressing the button three times within two seconds increases or decreases the power of the heated e-liquid to meet the needs of different users.

[0041] The e-liquid atomizer assembly 200 includes an e-liquid cup 210, a central cylinder 220, and a ceramic heating tube 230. The e-liquid cup 210 is positioned within the housing 100, between the mouthpiece 110 and the cylindrical support 310. Its bottom surface is provided with an e-liquid cup through-hole 211. The e-liquid cup 210 stores solid or paste e-liquid, and can also be used to store liquid e-liquid.

[0042] The central tube 220 is placed within the oil cup 210. If the oil cup 210 stores tobacco liquid, the perimeter of the central tube's bottom is sealed to the bottom surface of the oil cup 210. This sealing connection can be integrally formed, sealed with a sealing strip, or fixed with sealant. The oil cup 210 stores tobacco liquid, and the central tube 220 and oil cup 210 are sealed to prevent tobacco liquid leakage from the connection between the two.

[0043] Preferably, an annular groove 212 is provided at the bottom of the oil cup 210 , and the bottom of the oil cup 210 is placed in the annular groove 212 and is in close contact with the annular groove 212 for sealing connection therewith.

[0047] The sealing silicone cover 130 is formed with a centrally formed mating tube 131, which fits over the upper portion of the central tube 220 and wraps around the top of the central tube 220. Preferably, the outer diameter of the upper portion of the central tube 220 is smaller than the outer diameter of the lower portion of the central tube 220, so that atomized e-liquid gathers at the upper portion of the central tube 220, increasing its concentration.

[0048] The mouthpiece 110, which covers the housing 100 and the sealing silicone cover 130, includes a top cover 114 and a ring wall 115 disposed below the top cover 114. The outlet 111 is located in the center of the top cover 114. The outlet 111, the mating tube 131, the central tube 220, and the ceramic heating tube 230 share a common central axis. When the ceramic heating tube 230 generates heat and atomizes the e-liquid, the atomized e-liquid is sequentially discharged from the central tube 220, the mating tube 131, and the outlet 111 for inhalation by the user.

[0049] Specifically, the outlet 111 extends downward from the center of the top cover 114 and is trumpet-shaped. The bottom of the outlet 111 is connected to the top of the matching cylinder 131 .

[0050] The sealing silicone cover 130 is also provided with several insertion holes 132. The top cover 114 is provided with insertion posts 116.

When the cigarette holder 110 needs to add more liquid, the cigarette holder 110 is opened and the liquid is added to the liquid cup 210 through the insertion holes 132.

[0051] The periphery of the top cover 114 extends out of the annular wall 115 to form a step. During installation, the annular wall 115 is inserted into the housing 100 and the top cover 114 is attached to the top of the housing 100.

[0052] Preferably, an observation window is provided on the housing 100 at a position corresponding to the oil cup 210 , and the amount of the e-liquid in the oil cup 210 can be observed through the observation window.

[0053] Preferably, the outer diameters of the annular wall 115 of the top cover 114, the sealing silicone cover 130, and the oil cup 210 are equal, allowing them to be neatly stacked within the housing 100. Notch 1, Notch 2, and Notch 3 are respectively provided on the outer circumferences of the annular wall 115 of the top cover 114, the sealing silicone cover 130, and the oil cup 210. The inner wall of the housing 100 is provided with a ridge that inserts into Notch 1, Notch 2, and Notch 3, thereby preventing the top cover 114, the sealing silicone cover 130, and the oil cup 210 from rotating.

[0054] Preferably, the bottom cover 120 is provided with a plurality of fourth through holes. The lower portion of the housing 100 can be connected to a cigarette 400. The smoke generated by the burning cigarette 400 enters the housing 100 through the fourth through holes, then reaches the cylindrical support 310, passes through the gap within the cylindrical support 310, enters the central cylinder 220 and the ceramic heating tube 230, and then floats out through the mating cylinder 131 of the sealing cover and the outlet 111 of the mouthpiece 110. The electronic cigarette filter can be used to inhale atomized tobacco oil alone, an external cigarette 400 alone, or both atomized tobacco oil and an external cigarette 400, thus meeting the various needs of users.
