Description

Technical Field

[0001] The present invention relates to the technical field of smoking devices, and particularly to a cleaning device for an e-cigarette mouthpiece. Background Art

[0002] With the development of technology, people have switched from smoking ordinary tobacco to e-cigarettes. Among them, the e-liquid of an e-cigarette refers to the atomizer part of the e-cigarette. There is e-liquid in the atomizer. After the e-liquid is atomized by the heating element of the atomizer, it is inhaled by the user after passing through the atomization channel and the mouthpiece. When the mouthpiece is used, saliva or e-liquid will remain on the mouthpiece, or when there is dust or stains on the mouthpiece, there is no dedicated cleaning device for the mouthpiece to clean it. Usually, it is wiped with a tissue or an alcohol cloth, which is very troublesome and inconvenient to carry.

[0003] There are also some e-cigarettes equipped with a cleaning structure. The cleaning structure is arranged in the atomizer. When the e-cigarette is used for a long time, the cleaning structure needs to be replaced. It is very inconvenient to disassemble and assemble the cleaning structure. Arranging the cleaning structure in the atomizer not only increases the assembly process, but also increases the cost of the e-cigarette. Summary of the Invention

[0029] As Figures 1 to 3 shown, the cleaning device for an e-cigarette mouthpiece includes a housing structure and a cleaning member 13 connected to the housing structure. The housing structure includes an outer shell 11 and an inner shell 12. The inner shell 12 is connected inside the outer shell 11. The inner shell 12 includes a mounting hole 101 and a cavity 102 for cleaning the e-cigarette mouthpiece. The mounting hole 101 communicates with the cavity 102. The cleaning member 13 includes a cleaning portion 131. A part of the cleaning portion 131 passes through the mounting hole 101 and is arranged in the cavity 102, and another part of the cleaning portion 131 is arranged between the outer shell 11 and the inner shell 12. The cleaning device is used to clean the mouthpiece of the e-cigarette. The cleaning device is sleeved on the e-cigarette so that the mouthpiece of the e-cigarette is located in the cavity 102 of the inner shell 12. The outer shell 11 of the cleaning device is rotated so that the cleaning device rotates relative to the mouthpiece. At this time, the cleaning portion 131 of the cleaning member 13 located in the cavity 102 wipes the mouthpiece by rotation, thereby playing a role in cleaning the mouthpiece. In this embodiment, the outer shell 11 is a columnar structure, such as a cylindrical or rectangular columnar structure. The inner shell 12 and the outer shell 11 can be connected by means of riveting or snap connection, etc. Taking riveting connection as an example, the inner shell 12 and the outer shell 11 are fixed inside the outer shell 11 by interference fit. Taking snap connection as an example, a plurality of clamping blocks are fixedly connected to the inner wall of the outer shell 11. Each clamping block is arranged circumferentially around the inner wall of the outer shell 11. The inner shell 12 is provided with a plurality of clamping grooves that cooperate with the clamping blocks. The clamping blocks are arranged in the clamping grooves to fixedly connect the inner shell 12 and the outer shell 11.

[0030] The cleaning device of the present invention is provided with a cleaning member 13 in the cavity 102 of the inner shell 12. When there is residual e-liquid, saliva or other contaminants on the mouthpiece of the e-cigarette, the mouthpiece is placed in the cavity 102 so that the mouthpiece contacts the cleaning member 13. The cleaning device is rotated to make the cleaning member 13 rotate and wipe on the outer wall of the mouthpiece, thereby wiping the mouthpiece clean. Using the cleaning device to clean the mouthpiece is not only clean and hygienic, but also convenient to operate and very convenient for maintenance when needed.

[0031] Please continue to refer to Figures 1 to 3, the cleaning member 13 includes a liquid guiding portion 132. One end of the liquid guiding portion 132 is fixedly connected to the cleaning portion 131, that is, the cleaning portion 131 and the liquid guiding portion 132 are of an integral structure. The other end of the liquid guiding portion 132 is disposed between the inner shell 12 and the outer shell 11. The liquid guiding portion 132 is used for fixing and limiting the cleaning member 13; both the cleaning portion 131 and the liquid guiding portion 132 are arc-shaped, which are used to match with the suction nozzle, so that the contact area between the suction nozzle and the cleaning portion 131 is larger, the effective area of wiping by the suction nozzle is increased, and the cleaning member 13 is prevented from falling off. In this embodiment, preferably two cleaning members 13 are provided, and preferably two mounting holes 101 are provided. The cleaning portions 131 of the respective cleaning members 13 are respectively disposed in the respective mounting holes 101, and the two mounting holes 101 are oppositely arranged; the number of the mounting holes 101 and the cleaning members 13 may also be 3, 4, etc., which can be selected according to needs.

[0032] Preferably, a receiving chamber 103 is formed between the outer shell 11, the inner shell 12 and the cleaning member 13. The receiving chamber 103 is used for containing liquid. The liquid can penetrate to the cleaning portion 131 through the liquid guiding portion 132. When the suction nozzle needs to be cleaned, the cleaning portion 131 containing the liquid can wipe the suction nozzle cleaner and can also disinfect the suction nozzle. In this embodiment, the liquid is, for example, water, alcohol or cleaning liquid, etc., but is not limited thereto.

[0033] In another preferred embodiment, a receiving chamber 103 is formed between the outer shell 11 and the inner shell 12. The receiving chamber 103 is provided with a plurality of liquid leakage holes. The liquid leakage holes are arranged opposite to the liquid guiding portion 132 in the vertical direction, or the liquid guiding portion 132 covers the liquid leakage holes. The liquid can flow to the liquid guiding portion 132 through the liquid leakage holes under the action of gravity or air pressure extrusion.
