Description

Technical Field

[0001] This invention relates to the field of purification device technology, specifically to a purification device for reducing the harm of secondhand smoke. Background Technology

[0002] In today's society, due to work pressure or family troubles, more and more people are smoking. Many non-smokers are also harmed by smoking because smokers produce substances called secondhand smoke. Secondhand smoke mainly consists of the smoke exhaled by smokers and the smoke produced when cigarettes burn. These substances can cause health problems, mainly leading to asthma, pneumonia, lung cancer, high blood pressure, heart disease, and reproductive development disorders.

[0003] In a relatively enclosed environment, both smokers and non-smokers are harmed by secondhand smoke. Currently, indoor air purification is mainly achieved through air purifiers. Air purifiers can adsorb, decompose, or transform various pollutants in the air (generally including PM2.5, dust, pollen, secondhand smoke, etc.), effectively improving air cleanliness.

[0004] However, air purifiers require a certain amount of time to adsorb, decompose, and transform secondhand smoke in the air, and they cannot completely purify it. This is because tobacco smoke adheres to surfaces such as clothes, furniture, carpets, walls, and even hair and skin. These residues can remain for days, weeks, or even months, continuously harming health. If non-smokers and smokers are in a relatively enclosed environment, secondhand smoke has already harmed their health while they are smoking. Therefore, a purification device that can reduce the harm of secondhand smoke is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a purification device to reduce the harm of secondhand smoke, in order to solve the problem that existing air purifiers require a certain amount of time to adsorb, decompose and transform secondhand smoke in the air, and cannot completely purify the secondhand smoke in the air, because tobacco smoke is adsorbed on surfaces such as clothes, furniture, carpets, walls and even hair and skin, and these residues can exist for days, weeks or even months, continuously harming health.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a purification device for reducing the harm of secondhand smoke, comprising a purification cylinder, a mouthpiece, and an end cap. One end of the purification cylinder is provided with a detachable mouthpiece, and the other end of the purification cylinder is provided with a detachable end cap. The mouthpiece has a sealing ring inside for securing the cigarette. The mouthpiece end is provided with a first one-way air inlet valve. The purification cylinder includes an outer shell and an inner liner. The outer shell is fitted onto the outside of the inner liner, forming a purification chamber between the outer shell and the inner liner. The purification chamber is filled with an adsorption purification layer. One end of the inner liner has evenly distributed overflow holes penetrating the purification chamber. An air inlet hole is provided at the center of the end cap. A second one-way air inlet valve is provided inside the air inlet hole. An air outlet hole penetrating the purification chamber is evenly distributed on one side of the end cap surface surrounding the air inlet hole.

[0007] The purification cylinder has a first external thread at one end for mounting the smoking nozzle, and the smoking nozzle has a first internal thread at its end that mates with the first external thread. The smoking nozzle is threadedly connected to the purification cylinder through the first internal thread and the first external thread.

[0008] The purification cylinder has a second external thread at one end for mounting the end cap, and the end cap has a second internal thread that mates with the second external thread. The end cap is threadedly connected to the purification cylinder through the engagement of the second internal thread and the second external thread.

[0009] The outer shell and inner liner are made of one or more of the following materials: metal, ceramic, glass, and plastic.

[0010] The material of the adsorption and purification layer is one or a combination of activated carbon, activated carbon fiber, filter cotton, and electrostatic cotton.

[0011] The end cap is made of one of the following materials: porous metal, plastic, ceramic, or glass.

[0012] The material of the smoking mouthpiece is one of metal, plastic, or ceramic.

[0013] The first one-way intake valve and the second one-way intake valve are made of one of the following materials: metal, plastic, or ceramic.

[0014] The sealing ring is made of one of the following materials: fluororubber, nitrile rubber, silicone rubber, and EPDM rubber.

[0015] The inner diameter of the mouthpiece, the inner diameter of the inner liner, and the inner diameter of the air inlet are the same.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention uses a sealing ring to fix the cigarette inside the mouthpiece, with the cigarette extending into the inner liner. When the smoker inhales through the mouthpiece, the smoke is drawn out through the first one-way air intake valve on the mouthpiece, while external air enters the inner liner through the second one-way air intake valve on the air intake hole, ensuring sufficient oxygen for cigarette combustion. Secondhand smoke generated by cigarette combustion flows into the purification chamber through the overflow hole. The adsorption and purification layer in the purification chamber adsorbs harmful substances such as tar, ammonia, nicotine, suspended particles, and PM2.5 from the secondhand smoke, thereby purifying the smoke. The purified smoke is then discharged through the air outlet. By passing through this purification device, the smoke generated by the smoker can be purified in a timely manner, reducing the emission of secondhand smoke and thus reducing the harm of secondhand smoke to the body.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Please see Figure 1-6This embodiment provides a technical solution: a purification device for reducing the harm of secondhand smoke, including a purification cylinder 10, a smoking mouthpiece 20 and an end cap 30. One end of the purification cylinder 10 is provided with a detachable smoking mouthpiece 20. The end of the purification cylinder 10 for installing the smoking mouthpiece 20 is provided with a first external thread. The end of the smoking mouthpiece 20 is provided with a first internal thread that mates with the first external thread. The smoking mouthpiece 20 is threadedly connected to the purification cylinder 10 through the first internal thread and the first external thread. The threaded connection makes it easy to remove the smoking mouthpiece 20 from the purification cylinder 10. When smoking is needed, the smoking mouthpiece 20 is first removed, then the cigarette is clipped onto the smoking mouthpiece 20, and then the smoking mouthpiece 20 is installed on the purification cylinder 10 through the threaded connection. At the same time, the cigarette is inserted into the purification cylinder 10.

[0027] The purification cylinder 10 has a detachable end cap 30 at the other end. The end of the purification cylinder 10 for installing the end cap 30 has a second external thread, and the end cap 30 has a second internal thread that mates with the second external thread. The end cap 30 is threadedly connected to the purification cylinder 10 through the engagement of the second internal thread and the second external thread. The threaded connection makes it easy to remove the end cap 30 from the purification cylinder 10. When it is necessary to clean the soot inside the inner liner 12, the end cap 30 can be removed, and then the soot inside the inner liner 12 can be poured out.

[0028] The cigarette holder 20 has a sealing ring 22 inside to secure the cigarette. The sealing ring 22 is made of one of the following materials: fluororubber, nitrile rubber, silicone, or EPDM rubber. The sealing ring 22 can be made with different inner and outer diameters according to requirements and is easy to disassemble and replace. Its function is to prevent smoke from passing through the outside of the cigarette holder 20, thus providing a seal and securing the cigarette.

[0029] When in use, first remove the cigarette mouthpiece 20 from the purification cylinder 10, then insert the cigarette mouthpiece into the sealing ring 22 to hold and fix the cigarette in place by the sealing ring 22, then insert the cigarette into the inner liner 12, and install the cigarette mouthpiece 20 onto the purification cylinder 10 by means of threaded connection.

[0030] The mouthpiece 20 is fixedly equipped with a first one-way air inlet valve 21. The airflow direction of the first one-way air inlet valve 21 is outward. When the smoker smokes, the smoker can inhale the smoke through the mouthpiece 20.

[0031] The first one-way intake valve 21 is made of one of the following materials: metal, plastic, or ceramic. Its function is to ensure that the flue gas can only flow in one direction and that the airflow resistance is small when flowing in the forward direction.

[0032] The purification cylinder 10 includes an outer shell 11 and an inner liner 12. The outer shell 11 is fitted onto the outside of the inner liner 12. The materials of the outer shell 11 and the inner liner 12 are one or more combinations of metal, ceramic, glass, and plastic. The inner diameter, outer diameter, length, and wall thickness of the outer shell 11 and the inner liner 12 can be made according to requirements. Its function is to provide support and structural stability for the purification device to reduce secondhand smoke and to fix the adsorption purification layer 14.

[0033] The outer shell 11 and the inner liner 12 form a purification chamber 13. The purification chamber 13 is filled with an adsorption purification layer 14. The material of the adsorption purification layer 14 is one or a combination of activated carbon, activated carbon fiber, filter cotton, and electrostatic cotton. Its function is to adsorb harmful substances such as tar, ammonia, nicotine, suspended particles, and PM2.5 in secondhand smoke, thereby purifying the air.

[0034] The adsorption purification layer 14 can be wound or filled as required. After a period of use, the end cap 30 can be removed, and the adsorption purification layer 14 inside the purification chamber 13 can be taken out and replaced.

[0035] The inner liner 12 has an overflow hole 15 evenly distributed at one end, penetrating the purification chamber 13. The end cap 30 has an air inlet 31 at its center, and a second one-way air inlet valve 32 is fixedly installed inside the air inlet 31. The end cap 30 has an outlet hole 33 evenly distributed around one side of the air inlet 31, penetrating the purification chamber 13. When a smoker smokes through the mouthpiece 20, external air flows into the inner liner 12 through the second one-way air inlet valve 32 to provide oxygen for the cigarette to burn. Then, the oxygen produced during the cigarette combustion flows into the purification chamber 13 through the overflow hole 15. The adsorption and purification layer 14 in the purification chamber 13 adsorbs harmful substances such as tar, ammonia, nicotine, suspended particles, and PM2.5 in secondhand smoke, thereby purifying the smoke. The purified smoke is then discharged through the outlet hole 33.

[0036] The end cap 30 is made of one of porous metal, plastic, ceramic, or glass, with a thickness of 1-10mm. The shape of the air inlet 31 used to install the second one-way air inlet valve 32 can be any of the following: circular, elliptical, polygonal, or irregular. The function of the end cap 30 is to prevent the smoke inside the inner liner 12 from flowing out, and at the same time, it can provide a fixing effect for the adsorption and purification layer 14.

[0037] The second one-way air intake valve 32 is made of one of the following materials: metal, plastic, or ceramic. Its function is to ensure that the airflow can only flow in one direction and that the airflow resistance is small when flowing in the forward direction, so that the external air can flow into the inner liner 12 and prevent the smoke from the cigarette burning inside the inner liner 12 from flowing in through the air intake hole 31.

[0038] The mouthpiece 20 is made of one of the following materials: metal, plastic, or ceramic.

[0039] The inner diameters of the mouthpiece 20, the inner liner 12, and the air inlet 31 are the same. When a smoker smokes through the mouthpiece 20, the smoke is drawn out through the cavity inside the mouthpiece 20, which causes the atmospheric pressure inside the inner liner 12 to decrease. Then, external air enters the inner liner 12 through the second one-way air inlet valve 32 inside the air inlet 31, ensuring that the atmospheric pressure inside the inner liner 12 is the same as that outside, and at the same time ensuring that there is enough oxygen inside the inner liner 12 for the cigarette to burn.

[0040] Working principle: In use, first remove the cigarette holder 20 from the purification cylinder 10, then fix the cigarette in the cigarette holder 20 using the sealing ring 22, then light the cigarette and insert it into the inner liner 12. Then, thread the cigarette holder 20 onto the purification cylinder 10. The smoker can then smoke through the cigarette holder 20. When the smoker smokes through the cigarette holder 20, the smoke is drawn out through the first one-way air inlet valve 21 on the cigarette holder 20. At the same time, outside air enters the inner liner 12 through the second one-way air inlet valve 32 on the air inlet 31, ensuring sufficient oxygen for cigarette combustion. The secondhand smoke produced by the cigarette combustion flows into the purification chamber 13 through the overflow hole 15. The adsorption purification layer 14 in the purification chamber 13 adsorbs harmful substances such as tar, ammonia, nicotine, suspended particles, and PM2.5 in the secondhand smoke, thereby purifying the smoke. Then, the purified smoke is discharged through the air outlet 33. The smoke produced by the smoker passes through this purification device, which can promptly purify the smoke produced by the smoker and reduce the emission of secondhand smoke.

[0041] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
