[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] like Figures 1 to 3 As shown, this utility model discloses an electronic cigarette with recyclable and purified smoke, comprising a shell 1, an atomizing device 2, and a purification and filtration device 3. The shell 1 is divided into two independent chambers, namely an atomizing chamber 11 and a recycling and purification chamber 12. The shell 1 is also provided with a mouthpiece 13, a smoke inlet 14, and a smoke outlet 15. The mouthpiece 13 is connected to the atomizing chamber 11. The atomizing device 2 is installed in the atomizing chamber 11. The smoke inlet 14 and the smoke outlet 15 are respectively connected to the recycling and purification chamber 12. The purification and filtration device 3 is installed in the recycling and purification chamber 12 and is located on the smoke path between the smoke inlet 14 and the smoke outlet 15.
[0021] The atomizing chamber 11 of the electronic cigarette housing 1 is divided into sections using the traditional disposable electronic cigarette body: for installing the atomizing device 2, integrating an ergonomically designed mouthpiece 13, an oil-retaining cotton 21 made of high-density fiber, a heating wire, a battery 23, and a main board 24 to achieve the atomizing function.
[0022] The recycling and purification chamber 12 of the electronic cigarette casing 1 is divided into a smoke recycling and purification device, including a smoke inlet 14, a purification filter device 3, and a smoke outlet 15, forming a closed-loop purification system.
[0023] This structure achieves unidirectional airflow control by making the atomizing chamber 11 and the recovery and purification chamber 12 independent of each other, thus avoiding secondary pollution.
[0024] The recyclable and purified e-cigarette also includes an upper purification seal 4 and a lower purification seal 5. The upper purification seal 4 and the lower purification seal 5 are respectively connected to the top and bottom of the purification filter device 3. Both the upper purification seal 4 and the lower purification seal 5 are provided with air vents, and the air vents of the upper purification seal 4 and the lower purification seal 5 are aligned with the purification filter device 3.
[0025] The purification chamber 12 is equipped with a flow guide 17, which extends from the smoke inlet 14 to the purification filter 3. The flow guide 17 serves as a channel to guide the inhaled smoke into the purification filter 3.
[0026] The upper and lower purification seals 4 and 5 are made of silicone sealing rings. The smoke inlet 14, the guide channel 17, and the air passage of the silicone sealing ring together form the inlet channel for exhaled smoke. The upper purification seal 4 connects to the guide channel 17 and the purification filter device 3, and the lower purification seal 5 connects to the purification filter device 3 and the smoke outlet 15. This ensures that the smoke exhaled by the user from the smoke inlet 14 is directed into the purification filter device 3. After purification and filtration, the clean gas is discharged from the smoke outlet 15, ensuring that the purified gas meets emission standards.
[0027] The smoke inlet 14 has an inner groove 18 on its outer side. The structure of the inner grooves 18 on both sides makes the smoke inlet 14 fit the shape of the human mouth better, making it convenient to align the mouth with the smoke inlet 14 when exhaling, so that the smoke enters the recovery and purification chamber 12.
[0028] like Figures 4 to 6 As shown, the purification and filtration device 3 has a multi-layer composite filter structure. This multi-layer composite filter structure can be a single piece of fiberglass cloth 31 or meltblown cloth 32, or it can use fiberglass cloth 31 or meltblown cloth 32 as the filter base, combined with one or more of a water-absorbing layer 33 and a catalytic decomposition layer 34. The water-absorbing layer 33 is used to absorb moisture from the gas. Since moisture can adhere to the filter screen and clog the mesh, affecting gas passage and thus the filtration and purification effect, a water-absorbing layer 33 can be installed at the front end of the filter screen to absorb moisture from the gas, thereby reducing the impact of moisture on the filtration and purification effect.
[0029] The catalytic decomposition layer 34 can contain various catalytic substances, including carbon dioxide absorbents, noble metal-oxide composite catalysts, and activated carbon. Human exhaled gases consist of carbon dioxide, water vapor, volatile organic compounds (VOCs), and odorous substances. After entering the multi-layer composite filter structure, carbon dioxide is absorbed by the carbon dioxide absorbent, water vapor is absorbed by the water-absorbing layer, volatile organic compounds (such as nicotine) are absorbed by the noble metal-oxide composite catalyst, and odorous substances are absorbed by the activated carbon. The noble metal-oxide composite catalyst, such as Pt-Pd / Al2O3-TiO2, utilizes the low-temperature activity of noble metals (starting below 100℃) and the oxygen storage capacity of oxides to maintain a VOCs decomposition efficiency of over 80% even at humidity ≤95%.
[0030] The catalytic decomposition layer 34 can adopt a honeycomb catalyst support structure to increase the catalytic area and improve the catalytic efficiency.
[0031] Figure 4 The structure used is a single fiberglass cloth 31 or meltblown cloth 32; Figure 5 The structure is a combination of fiberglass cloth 31 or meltblown cloth 32 and water-absorbing layer 33. The water-absorbing layer 33 and fiberglass cloth 31 or meltblown cloth 32 are arranged sequentially along the airflow direction. Figure 6 The structure adopts a combination of fiberglass cloth 31 or meltblown cloth 32 with water-absorbing layer 33 and catalytic decomposition layer 34. The water-absorbing layer 33, fiberglass cloth 31 or meltblown cloth 32 and catalytic decomposition layer 34 are arranged sequentially along the airflow direction.
[0032] The purification and filtration device 3 adopts a multi-layer composite filter structure, which includes a water-absorbing layer 33, a catalytic decomposition layer 34, and a combination of materials. Various combinations can achieve the following filtration methods:
[0033] Physical filtration: Fiberglass cloth 31 or meltblown cloth 32 is used to intercept aerosol particles.
[0034] Chemical decomposition: Catalytic decomposition layer 34 is used to adsorb harmful substances (such as nicotine) and degrade harmful components.
[0035] like Figures 2 to 3 As shown, the atomizing device 2 includes an oil-storing cotton 21, a heating atomizing body 22, a battery 23, and a main board 24. The oil-storing cotton 21, the heating atomizing body 22, the battery 23, and the main board 24 are all located inside the atomizing chamber 11. The housing 1 is also provided with an airflow inlet 16, which is connected to the atomizing chamber 11. The heating atomizing body 22 is connected to the mouthpiece 13. The oil-storing cotton 21 is wrapped around the heating atomizing body 22. The main board 24 is connected to and controls the heating atomizing body 22. The battery 23 is connected to the main board 24.
[0036] Battery 23 provides power for the operation of the entire electronic cigarette. Heating atomizer 22 includes heating wire. Oil storage cotton 21 provides atomizing oil to heating wire. Main board 24 controls the power supply of heating wire to generate heat to heat the atomizing oil in oil storage cotton 21 for atomization. When the user inhales, the airflow enters the atomization chamber 11 from airflow inlet 16. At this time, main board 24 controls heating wire to heat atomizing oil to generate atomized gas, which flows with the airflow to the mouthpiece 13.
[0037] The atomizing device 2 also includes an upper atomizing seal 6 and a lower atomizing seal 7. The upper atomizing seal 6 and the lower atomizing seal 7 are installed in the atomizing chamber 11 and form a heating atomizing area 19. The heating atomizing body 22 and the oil storage cotton 21 are located in the heating atomizing area 19. Both the upper atomizing seal 6 and the lower atomizing seal 7 are provided with air passages. The air passage of the upper atomizing seal 6 is aligned with the upper end of the heating atomizing body 22 and the nozzle 13, and the air passage of the lower atomizing seal 7 is aligned with the lower end of the heating atomizing body 22.
[0038] The upper atomizing seal 6 and the lower atomizing seal 7 use sealing silicone rings to seal the oil storage cotton 21, preventing atomizing oil from leaking onto the battery 23 and the main board 24 and affecting its use. Only the upper atomizing seal 6 and the lower atomizing seal 7 have vent holes to allow airflow to pass through the heating wire to generate atomized gas.
[0039] This structure adopts an innovative split design, dividing the product into two main functional modules, left and right. For example... Figure 3As shown, the left side represents the main body of a traditional disposable electronic cigarette, integrating electronic components and an atomization system: the mouthpiece 13 features an ergonomic streamlined design, and the e-liquid reservoir 21 is made of high-density fiber material to ensure even e-liquid storage; the heating coil is equipped with a temperature control sensor, working with the battery 23 and the control board 24 to achieve precise atomization. The right side's smoke recovery and purification device constructs a highly efficient purification system. Its smoke inlet 14 has a guide channel 17 structure, which, together with a sealing silicone ring, enables unidirectional smoke introduction; the purification filter 3 uses a multi-layer composite filter, combined with a catalytic decomposition layer 34, to effectively intercept and degrade harmful substances; its internal structure employs a multi-layer composite filter structure, which uses... Figures 4 to 6 Multiple combinations are available to meet different levels of purification needs. The purified gas is discharged through a specially designed smoke outlet 15, ensuring environmental friendliness.
[0040] When operating the device, the user first activates the electronic cigarette on the left, atomizing the e-liquid through the heating coil before inhaling. Then, when exhaling, the user directs their breath towards the smoke inlet 14, and the exhaled smoke enters the purification and filtration device 3 through the smoke inlet 14 on the right. Guided by the flow guiding structure of the guide channel 17 and the purification upper seal 4, the smoke undergoes physical filtration and chemical decomposition through multiple layers of filters, and is finally discharged as clean gas through the air holes of the purification lower seal 5 and the atomization outlet, achieving full-process control of smoke from generation to purification.
[0041] This invention adds a smoke recovery and purification device to the traditional disposable electronic cigarette, which can purify and absorb the smoke generated during the inhalation of electronic cigarettes, thereby achieving the purpose of environmental protection and reducing environmental pollution.
[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
