Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] Example 1:

[0031] like Figure 1-7 As shown, this invention provides a portable cigarette smoke purifier, comprising a heat-insulated purifier body 1 with a hollow structure, a cigarette lighting chamber 2, a combustion reaction chamber 3, a cooling chamber 4, and a purification chamber arranged sequentially on the heat-insulated purifier body 1, as well as a fan 6, a power module 7, and a control switch module. The heat-insulated purifier body 1 has an air inlet and an exhaust outlet. The side panels of the heat-insulated purifier body 1 are made of hollow, heat-insulated stainless steel. When smokers use it, less heat generated by the cigarette lighting chamber 2 and the combustion reaction chamber 3 is transferred to the outer wall of the side panels of the heat-insulated purifier body 1, providing good heat insulation and reducing heat conduction between the cigarette lighting chamber 2 and the combustion reaction chamber 3 and the heat-insulated purifier body 1, preventing burns from user handling and improving safety and comfort. Figure 7As shown, the top plate 101 of the heat-insulating purifier body 1 has a cigarette ignition port 1011 for inserting a cigarette 13 into the cigarette ignition chamber 2 and several first one-way smoke inlets 1012 for cigarette smoke to enter the cigarette ignition chamber 2. The cigarette ignition port 1011 serves to limit and guide the cigarette 13 inserted into the cigarette ignition chamber 13. The first one-way smoke inlets 101 have a one-way check valve to prevent cigarette smoke from overflowing in the opposite direction. The combustion reaction chamber 3 is used to fully burn the cigarette smoke. The cooling chamber 4 is used to mix the flue gas discharged from the combustion reaction chamber 3 with the air and cool it down. The purification chamber is used to filter impurities in the mixed flue gas discharged from the cooling chamber 4. The fan 6 is used to drive air through the air inlet into the cooling chamber 4 and the purification chamber in sequence, and then discharge it through the exhaust port 1021, drive air into the cigarette ignition chamber 2, and drive cigarette smoke through the cigarette ignition chamber 2 into the combustion reaction chamber 3. The control switch module is electrically connected to the cigarette ignition chamber 2, the combustion reaction chamber 3, the purification chamber, the fan 6, and the power module 7, respectively.

[0032] As an optional implementation, such as Figure 2 As shown, the lighting chamber 2 is equipped with a cigarette lighter filament 201 positioned opposite the lighting port 1011, and the cigarette lighter filament 201 is electrically connected to the control switch module. The cigarette 13 passes through the lighting port 1011 and enters the lighting chamber 2, causing the cigarette lighter filament 201 to insert into the tobacco end of the cigarette 13. Then, the cigarette lighter filament 201 is energized and heats up, igniting the cigarette 13 at high temperature. Simultaneously, the control switch module drives the fan 6 to rotate at low speed, guiding outside air into the lighting chamber 2 through the first one-way smoke inlet 1012, allowing the cigarette 13 to burn quickly and efficiently. Furthermore, the fan 6 can also dissipate the heat generated by the combustion of the cigarette 13 within the lighting chamber 2 through the exhaust port 1021 of the base plate 102, preventing excessive air pressure in the lighting chamber 2. A portion of the tar produced by the silent combustion of the cigarette 13 can adhere to the inner wall of the lighting chamber 2; this can be easily cleaned by wiping, extending its service life.

[0033] As an optional implementation, such as Figure 1 , 5 As shown, the outer periphery of the top plate of the heat-insulating purifier body 1 bends upward along the axial direction to form a smoke collection hood 9 for covering the mouth and nose of the user. The smoke collection hood 9 has an opening 91 that is concentrically set with the cigarette lighter and convenient for the user to hold in the mouth. A gap is formed between the opening 91 and the mouthpiece end of the cigarette 13 to allow the cigarette smoke to flow. The inner diameter of the smoke collection hood 9 increases along the direction of cigarette smoke flow. When it is necessary to purify the cigarette smoke, the smoker holds the opening 91 of the smoke collection hood 9 in their mouth and exhales the cigarette smoke toward the top plate 101. The smoke collection hood 9 gathers and collects the cigarette smoke to prevent it from leaking out and controls the cigarette smoke to flow unidirectionally into the heat-insulating purifier body 1. The smoke then enters the combustion reaction chamber 3 for open flame combustion and purification through the first unidirectional smoke inlet 1012, the lighting chamber 2, and the second unidirectional smoke inlet 302.

[0034] As an optional implementation, such as Figure 2 ,3 As shown, the sidewall of the combustion reaction chamber 3 has several second one-way smoke inlets 302 connected to the ignition chamber 2 along its circumference. The second smoke inlet channel is preferably located in the middle of the sidewall of the combustion reaction chamber 3. The bottom plate 102 of the combustion reaction chamber 3 has a smoke exhaust port connected to the cooling chamber 4, and a honeycomb mesh plate is provided on the smoke exhaust port. The combustion reaction chamber 3 has an annular heating plate 301 with openings at both ends. A spirally arranged heating wire 3011 is tightly fitted to the inner wall of the heating plate and is electrically connected to the controller. A smoke inlet channel is formed between the upper opening of the heating plate and the top plate 101 of the combustion reaction chamber 3, and a combustion channel is formed between the inner walls of the annular heating plate 301. The lower opening of the heating plate is concentrically connected to the smoke exhaust port. Cigarette smoke entering through the second one-way smoke inlets 302 flows upward along the outer wall of the heating plate, and then, guided by the suction force of the fan 6, enters the combustion channel, extending the flow path of the cigarette smoke in the combustion reaction chamber 3, allowing the cigarette smoke to burn completely within the combustion reaction chamber 3. Furthermore, the combustion chamber 3 has a small combustion space, allowing the heating wire 3011 to heat up quickly and achieve high combustion efficiency. Cigarette smoke is fully combusted through the high-temperature combustion channel, effectively removing harmful substances and purifying the smoke. Moreover, the honeycomb mesh plate at the exhaust port increases the flow resistance of cigarette smoke, reduces its velocity, and significantly extends the combustion path, ensuring complete combustion within the combustion chamber 3 and high purification efficiency. The heating wire 3011 has a maximum combustion temperature of 1100℃-1200℃. Made of 0.5mm diameter exposed iron-chromium-aluminum, it withstands temperatures up to 1350℃, is not easily oxidized, has a long lifespan, and heats up extremely quickly, making it well-suited for high-temperature scenarios requiring immediate deployment. The combustion chamber 3 is made of quartz, ceramic, or corundum tubes that withstand ultra-high temperatures of 1600℃-1900℃, further extending its service life.

[0035] As an optional implementation, such as Figure 1 , 2 As shown in Figure 3, the air inlet consists of several circumferentially oriented air inlet holes 1031 on the air inlet side plate 103 located below the smoke hood 9. The air inlet holes 1031 are connected to the cooling chamber 4 via an L-shaped air inlet channel 10. The straight section 1001 of the L-shaped air inlet channel 10 is located above the combustion reaction chamber 3, and the vertical section 1002 of the L-shaped air inlet channel 10 penetrates the combustion reaction chamber 3 and extends to the cooling chamber 4. The high-temperature flue gas purified by combustion in the combustion reaction chamber 3 cannot be directly discharged; it needs to be cooled by guiding external air into the cooling chamber 4 through the L-shaped air inlet channel 10. The mixing of the high-temperature flue gas and external air is achieved by the suction of the fan 6. Preferably, the ratio of high-temperature flue gas to external air entering the cooling chamber 4 is 1:15. This ensures that even if the high-temperature flue gas reaches 1200°C, after mixing and cooling with external air in the cooling chamber 4, the discharged flue gas temperature is below 80°C, effectively preventing the problem of high-temperature flue gas easily scalding users.

[0036] As an optional implementation, the purification chamber is equipped with a purification component for purifying the mixed flue gas. The purification component includes any or any combination of a negative ion purifier and a purification filter element 5 to further filter and purify the flue gas after cooling.

[0037] As an optional implementation, such as Figure 2 As shown, an exhaust channel connecting the purification chamber and the exhaust port 1021 is formed between the outer wall of the power module 7 and the inner wall of the heat-insulating purifier body 1. The power module 7 is detachably connected to the heat-insulating purifier body 1. The power module 7 contains several batteries 701 connected in series and a protection plate 702 for protecting the batteries 701. The power module 7 is used to supply power to the smoke ignition chamber 2, combustion reaction chamber 3, cooling chamber 4, purification chamber, fan 6, and control switch module to ensure the safe and reliable operation of the device.

[0038] As an optional implementation, such as Figure 2 As shown, the control switch module includes a control motherboard 8 and switch buttons. The control motherboard 8 is electrically connected to the smoke ignition chamber 2, combustion reaction chamber 3, purification chamber, fan 6, and power module 7. The control motherboard 8 can be installed below the cooling chamber 4 to prevent damage from high-temperature flue gas. The switch buttons are used to control the power module 7 and fan 6 to turn on and off.

[0039] The purification process of this invention is as follows:

[0040] First, the smoker holds the opening 91 of the smoke collection hood 9 in their mouth, controlling the cigarette smoke to flow unidirectionally into the heat-insulating purifier body 1. The smoke then passes through the first unidirectional smoke inlet 1012, the lighting chamber 2, and the second unidirectional smoke inlet 302 into the combustion reaction chamber 3. Then, the heating wire 3011 is energized to burn, allowing the cigarette smoke to burn fully in the combustion reaction chamber 3, removing most of the harmful substances. Next, the fan 6 is started, drawing the high-temperature flue gas purified by combustion into the cooling chamber 4 for mixing and cooling. The cooled flue gas is then pushed through the purification filter element 5 to intercept and filter impurities in the flue gas before being discharged from the exhaust hole 1021 of the bottom plate 102. This invention features a simple structure, reasonable design, small size, and easy portability. Cigarette smoke is fully combusted in the combustion reaction chamber 3, resulting in excellent smoke purification and reducing the harm of cigarette smoke to smokers and those exposed to secondhand smoke. Furthermore, the high-temperature smoke emitted from the combustion reaction chamber 3 is cooled by the cooling chamber 4, effectively preventing burns to users. Simultaneously, the hollow, insulated stainless steel body 1 provides excellent heat insulation, reducing heat conduction and further preventing burns, thus improving safety and comfort and increasing the utilization rate of the cigarette smoke purifier.

[0041] Example 2:

[0042] The difference between Example 2 and Example 1 is as follows: Figure 1 , 4 As shown, the heat-insulated purifier body 1 includes a detachable upper shell 14 and a lower shell 15. The side plates of the upper shell 14 are hollow heat-insulated stainless steel structures, with accommodating cavities for installing the smoke ignition chamber 2, combustion reaction chamber 3, cooling chamber 4, purification chamber, and fan 6, isolating the smoke ignition chamber 2 and combustion reaction chamber 3 from heat conduction with the upper shell 14, ensuring the heat insulation performance of the heat-insulated purifier body 1. The lower shell 15 has accommodating cavities for detachably installing the purification chamber and power module 7. Preferably, the upper shell 14 and lower shell 15 are assembled together by a threaded connection, facilitating disassembly and installation. Since the flue gas flowing through the battery 701 module is low-temperature flue gas that has undergone cooling treatment, it will not damage the battery 701 module, improving operational stability and extending service life. The side plates of the lower shell 15 can be made of single-layer stainless steel, reducing manufacturing costs while ensuring safety and comfort during use.

[0043] Example 3:

[0044] The difference between Example 3 and Example 1 is as follows: Figure 2 , 4 As shown, it also includes a first switch button 11 and a second switch button 12. The first switch button 11 is installed on the top plate 101 and is used to control the fan 6 to turn on and off. The fan speed can also be adjusted by the first switch button 11 to adapt to different usage requirements. The second switch button 12 is installed on the side plate of the lower housing 15 corresponding to the power module 7 and is used to control the power module 7 to turn on and off.

[0045] As an optional implementation, such as Figure 2 As shown, the power module 7 is detachably installed on the lower housing 15. An exhaust channel is formed between the outer wall of the power module 7 and the inner wall of the lower housing 15, which connects the purification chamber and the exhaust port 1021. The power module 7 is provided with a number of batteries 701 connected in series and a protection plate 702 for protecting the batteries 701.
