[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette that prevents condensate from clogging the air tube. Background Technology

[0002] An electronic cigarette is an electronic device designed to simulate the feel and taste of a traditional cigarette, but it does not burn tobacco like a traditional cigarette. It typically consists of a heating element, a battery, and a liquid-containing container. When the user inhales, the heating element heats the liquid to produce vapor, which the user inhales instead of smoke. In existing electronic cigarettes, condensation forms within the vapor channel during use. This condensation flows down the channel and, when it enters the confined airway, can clog it, affecting airflow and hindering normal use. Utility Model Content

[0032] One embodiment of this utility model proposes an electronic cigarette that prevents condensate from clogging the gas tube, see reference. Figures 1 to 3 ,in, Figure 3 The arrows in the text indicate the airflow direction. Electronic cigarettes include:

[0033] Host;

[0034] Nozzle 1 is installed on the top of the main unit;

[0035] Microphone 2 is used to sense the user's inhalation action to activate the electronic cigarette;

[0036] Oil tank 3 is used to store e-liquid;

[0037] Heating wire 4 is connected to the bottom of the oil tank 3 and is used to heat the e-liquid inside the oil storage chamber;

[0038] The smoke chamber 5 has a first end connected to the mouthpiece 1 and a second end extending to the bottom of the heating wire 4.

[0039] Airway 6, the first end of which is connected to the outside of the electronic cigarette, and the second end of which is connected to the second end of the smoke chamber 5;

[0040] A baffle 7 is filled in the air passage 6, and the baffle 7 has an air hole for the gas in the air passage 6 to flow into the smoke chamber 5. The air hole is located away from the bottom of the smoke chamber 5.

[0041] In this embodiment, the structure of existing electronic cigarettes is improved by adding a baffle 7 inside the airway 6. The baffle 7 fills the airway 6 and forms a physical barrier. The air vents on the baffle 7 are located away from the bottom of the smoke chamber 5. Utilizing the principles of gravity and airflow direction control, it ensures that condensate cannot flow back into the airway 6, fundamentally avoiding blockage. Unobstructed airway 6 ensures a stable vapor output, eliminating the need for frequent device cleaning and making the smoking process more continuous and smooth, thus improving device reliability and user satisfaction. By reducing condensate corrosion and blockage of the airway 6, the device failure rate is reduced, extending the lifespan of the electronic cigarette. The coordinated design of the baffle 7 and the air vents allows for precise airflow control, resulting in a more uniform airflow distribution within the smoke channel and improving the stability of the smoking experience.

[0042] Furthermore, the main unit, as the core component of the electronic cigarette, integrates components such as the battery 9 and a circuit board. The battery 9 provides power to the entire device, and the circuit board is responsible for receiving signals from the microphone 2 and controlling the working state of the heating wire 4. Specifically, the main unit includes a housing 8, the mouthpiece 1 is mounted on the top of the housing 8, and the housing 8 contains a battery 9 for power supply and a circuit board for controlling the operation of the electronic cigarette. The microphone 2, the heating wire 4, and the battery 9 are all connected to the circuit board.

[0043] Furthermore, the mouthpiece 1 adopts an ergonomic curved design and is installed on the top of the main unit to ensure user comfort when inhaling. The microphone 2 is embedded in the connection between the mouthpiece 1 and the main unit. When the user inhales, the microphone 2 senses changes in air pressure and sends an electrical signal to the control circuit board. The smoke chamber 5, as the main part of the smoke channel, is connected to the mouthpiece 1 at one end and extends downward to the bottom of the heating wire 4 at the other end. The air duct 6 is designed as an independent channel structure. The first end connects to the outside through the air inlet on the side wall of the main unit, and the second end intersects perpendicularly with the second end of the smoke chamber 5.

[0044] Furthermore, the mouthpiece 1 has an oil filling hole 10 on its side that communicates with the oil tank 3, and an oil-filling silicone 11 is installed between the mouthpiece 1 and the oil tank 3. In this embodiment, the oil filling hole 10 can be a circular through hole, and the oil-filling silicone 11 is formed into a sealing structure through injection molding. The silicone edge is provided with annular ribs, which are press-fitted with the inner wall of the mouthpiece 1 to ensure sealing. With this structure, the oil filling process does not need to contact the inside of the e-liquid tank 3, avoiding the entry of external contaminants into the oil tank 3.

[0045] Furthermore, a ceramic silicone rubber 12 is disposed between the heating wire 4 and the bottom of the e-liquid tank 3. In this embodiment, the ceramic silicone rubber 12 is provided because the high thermal conductivity of the ceramic substrate allows heat to be quickly conducted from the heating wire 4 to the e-liquid, greatly shortening the heating response time compared to the traditional cotton wick structure. The good sealing performance of the silicone layer reduces heat loss, greatly improving the e-liquid atomization efficiency. The high-temperature resistance of the ceramic material effectively prevents the risk of overheating caused by dry burning. As a heat buffer medium, the silicone layer prevents the heating wire 4 from directly contacting the metal wall of the e-liquid tank 3, eliminating the risk of short circuits.

[0046] Furthermore, a lower sealing silicone 13 is installed between the bottom of the oil tank 3 and the air passage 6. By adding the lower sealing silicone 13, the internal sealing of the electronic cigarette can be improved, preventing e-liquid from flowing into the air passage 6. The silicone material has excellent aging resistance and a longer service life in the e-liquid environment. The seal can be replaced separately, reducing the overall maintenance cost.

[0047] Furthermore, a vent pipe 14 for connecting the smoke chamber 5 and the air passage 6 is installed on the lower sealing silicone 13. In this embodiment, to ensure normal airflow between the smoke chamber 5 and the air passage 6 and to ensure the sealing of the structure, a small hole can be made in the lower sealing silicone 13, and the vent pipe 14 can be inserted into the hole to allow airflow. The vent pipe 14 can be made of metal to ensure structural stability and prevent blockage inside the air passage. The vent pipe 14 is inserted vertically into the lower sealing silicone 13, which can effectively prevent blockage inside the pipe. The unobstructed airflow path reduces inhalation resistance and improves the smoothness of smoking. Furthermore, the end of the vent pipe 14 that connects to the smoke chamber 5 is higher than the bottom surface of the smoke chamber 5. With this structure, even if there is condensate in the smoke chamber 5, it will remain on the bottom surface of the smoke chamber 5 due to gravity. Since the end of the vent pipe 14 is higher than the bottom surface of the smoke chamber 5, it can effectively prevent condensate from flowing directly into the vent pipe 14 and blocking it.

[0048] Furthermore, the stop block 7 is configured as an integrally molded structure with the lower sealing silicone 13. The seamless integration of the stop block 7 and the lower sealing silicone 13 eliminates assembly gaps, reducing leakage rates compared to a separate structure. This reduces the need for separate stop block 7 installation steps, avoids part loss, improves assembly efficiency, lowers manufacturing costs, and the integrated structure also offers greater stability and extends product lifespan.

[0049] Furthermore, a condensation cotton 15 is provided between the smoke chamber 5 and the lower sealing silicone 13. As a physical barrier, the condensation cotton 15 can effectively prevent condensate from entering the air passage 6, reducing the frequency of user cleaning of the air passage 6. The effective interception of condensate by the condensation cotton 15 can also reduce odor generation and maintain the purity of the smoke.

[0050] Furthermore, the heating wire 4 is connected to the control circuit board via a conductive electrode 16. The connection between the heating wire 4 and the control circuit board via the conductive electrode 16 eliminates the need for wires, simplifying the structure and improving connection stability. The independent conductive electrode 16 module design means that only the electrode module needs to be replaced during maintenance, reducing operating costs.

[0051] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
