Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and specifically to a smoke filter for electronic cigarettes. Background Technology

[0002] With the increasing global efforts to control tobacco use and the growing public awareness of health, the market for e-cigarettes as a substitute for traditional tobacco is expanding rapidly. However, existing e-cigarettes still have significant drawbacks in use: the aerosol produced by vaporization contains harmful substances such as formaldehyde and acetaldehyde, which pose potential risks to the respiratory system with long-term inhalation; at the same time, the cloyingly sweet smell from high-concentration flavorings can easily cause discomfort to those around them, and the limited variety of flavors makes it difficult to meet the diverse experience needs of users.

[0003] To address these issues, the industry has attempted to purify flue gas through physical filtration. However, traditional filtration devices often employ fixed filter cartridge structures, which have limitations such as rapid adsorption saturation, high replacement costs, and the inability to adjust the taste. While some solutions have incorporated water filtration concepts, the sealed cavity design prevents liquid replacement, leading to bacterial growth and unpleasant odors with prolonged use, ultimately impacting safety and sensory experience.

[0004] Therefore, developing a novel electronic cigarette filter device that combines high-efficiency filtration, aroma control, and refillable liquid has become a key technological direction for improving product safety and user experience. This device needs to achieve multiple functions, including harmful substance retention, aroma concentration adjustment, multi-liquid blending, and convenient liquid replacement, to meet consumers' dual pursuit of health reduction and personalized flavors. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a smoke filter for electronic cigarettes; it can realize multiple functions such as harmful substance interception, aroma concentration adjustment, multi-liquid blending and convenient liquid replacement.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is:

[0007] The smoke filter includes a mouthpiece, a water cup holder, a one-way valve, an air duct, and a water cup partition. The water cup holder is sealed at the bottom of the mouthpiece, with a hollow cylindrical part protruding inward from its center. The one-way valve is sealed at the top of the cylindrical part. The lower end of the air duct is fitted over the cylindrical part, and the upper end engages with the water cup partition. The upper end of the water cup partition engages with the top of the mouthpiece. The bottom of the space formed by the mouthpiece and the water cup holder is filled with filtrate. A meandering airflow channel is formed from the cylindrical part, the one-way valve, the gap between the cylindrical part and the air duct, the filtrate, the water cup partition, to the top outlet of the mouthpiece.

[0008] The bottom outer side of the cylindrical part forms a circumferentially arranged ridge; the bottom end of the air guide tube is inserted outside the ridge, forming a gas channel between the air guide tube and the outer side of the cylindrical part.

[0009] The one-way valve is a silicone sleeve; the main body is cylindrical, with a bucket lid partially connected to the top; the silicone sleeve covers the top of the cylindrical part.

[0010] The water cup partition includes a partition that mates with the mouthpiece, an air guide tube that extends axially from the top and bottom sides of the partition and connects to the top of the mouthpiece, and a connecting tube that connects to the air guide tube; the top of the air guide tube is inserted into the connecting tube and abuts against the partition; an air guide notch is formed on the partition; an air guide port is formed axially on the air guide tube; a cylindrical connecting part extends axially inward from the top of the mouthpiece; and the top of the air guide tube is fitted onto the lower end of the connecting part.

[0011] The notch on the partition is arranged circumferentially along the edge connecting to the inner wall of the nozzle; multiple air inlets are arranged circumferentially.

[0012] The water cup holder forms a water injection hole; the water injection hole is sealed with a silicone plug.

[0013] This invention filters the vapor generated by electronic cigarettes through a filter containing a filtrate, which can remove harmful substances from the vapor and also dilute the vapor, reducing its sweetness and aroma. By adding various filtrates such as soda, alcohol, and tea, the aroma can be blended, making the vapor more diverse. Attached Figure Description

[0019] The following embodiments are descriptions of specific implementations of the present invention. These descriptions are intended to facilitate understanding of the technical solutions of this application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present invention. All equivalent transformations that can be obtained from the description of the embodiments of the present invention should be within the scope of protection of the present invention.

[0020] like Figures 1 to 4As shown, the smoke filter of the electronic cigarette of the present invention includes a mouthpiece 1, a water cup holder 2, a one-way valve 3, an air guide tube 4, and a water cup partition 5; the water cup holder 2 is sealed at the bottom of the mouthpiece 1, and a hollow cylindrical part 21 protrudes inward from its center; the one-way valve 3 is sealed at the top of the cylindrical part 21; the lower end of the air guide tube 4 is sleeved outside the cylindrical part 21, and the upper end cooperates with the water cup partition 5; the upper end of the water cup partition 5 cooperates with the top of the mouthpiece 1; the bottom of the space formed by the mouthpiece 1 and the water cup holder 2 is filled with filter liquid 6.

[0021] A circumferentially arranged ridge 22 is formed on the outer side of the bottom of the cylindrical part 21; the bottom end of the air guide tube 4 is inserted outside the ridge 22 to form a gas channel between the air guide tube 4 and the outer side of the cylindrical part 21.

[0022] The one-way valve 4 is a silicone sleeve; the main body is cylindrical, with a bucket lid partially connected to the top; the silicone sleeve covers the top of the cylindrical part 21.

[0023] The water cup partition 5 includes a partition 51 that mates with the mouthpiece, air guide tubes 52 that axially protrude from the upper and lower sides of the partition and connect to the top of the mouthpiece, and a connecting tube 53 that connects to the air guide tube 4. The top end of the air guide tube 4 is inserted into the connecting tube 53 and abuts against the partition 51. An air guide notch 54 is formed on the partition 51; the notch 54 is arranged circumferentially along the periphery connecting to the inner wall of the mouthpiece 1. An air guide port 55 is axially formed on the air guide tube 52; multiple air guide ports 55 are arranged circumferentially.

[0024] The top of the suction nozzle 1 has an inwardly protruding cylindrical connecting part 11; the top of the air guide tube 52 is fitted onto the lower end of the connecting part 11.

[0025] The aforementioned structure forms a circuitous airflow channel from the cylindrical portion 21 of the water cup holder 2, the one-way valve 3, the gap between the cylindrical portion 21 and the air guide tube 4, the filter liquid 6, the notch 54 of the water cup partition 5, the air guide port 55 of the air guide tube 52, to the top outlet of the mouthpiece 1. The inhaled gas (smoke) must pass through the filter liquid 6 before it can be drawn out from the top of the mouthpiece 1.

[0026] Because the notch 54 is located around the periphery where it connects to the inner wall of the nozzle 1, the space formed by the nozzle 1, the water cup holder 2, the air guide tube 52, and the connecting tube 53 can accommodate the filtrate 6 even when the filter is placed flat. When the filter is placed upside down, the space formed by the inner wall of the nozzle 1 and the connecting part 11 can also accommodate the filtrate 6. Therefore, no matter how the filter is positioned, the filtrate 6 will not flow out from the air guide port 55.

[0027] In addition, the water cup holder 2 forms a water inlet 23; the water inlet 23 is sealed with a silicone plug 7. When it is necessary to replace or add filter liquid, it can be done through the water inlet 23.

[0028] The connection between the filter of this invention and the rest of the electronic cigarette is as follows: Figure 4 As shown; simply connect the filter to the electronic cigarette to use it.
