Description

TECHNICAL FIELD

The invention relates to the technical field of cigarette filters, in particular to an integrated cigarette filter that can light up, cut and put out a cigarette, hold ash and butts and filter smoke.

INTRODUCTION/BACKGROUND

Cigarettes are made from tobacco. In addition to dry tobacco, the main component contained in cigarettes, many others are chemically added. Smoke that comes from a burning cigarette contains about 4,000 chemicals, most of which are toxic substances, metamorphosis-inducing materials and carcinogens. Tar and nicotine are especially harmful. The sponge filter tip that a cigarette itself comes with has very limited ability to filter out toxic substances. Therefore, long-term smoking will seriously damage the health of smokers.
Second-hand smoke (SHS) is also known as passive smoking or environmental tobacco smoking (ETS). It's a mixture of smoke that comes from the burning of cigarettes or other tobacco products and a smoker exhales from the lungs. That is, passive smoking contains the mainstream smoke that a smoker exhales but also the sidestream smoke that comes from a cigarette or cigar or a tobacco pipe. Passive smoking contains over 4,000 hazardous chemicals, such as tar, ammonia, nicotine, aerosols, ultra-fine aerosols (PM2.5) and polonium-210, and dozens of carcinogens. As reported by the World Health Organization (W. H. O.), smoking is harmful to human beings in many ways, mainly causing asthma, pneumonia, lung cancer, hypertension, cardiopathy and genital hypoplasia, etc. Passive smoking is no less harmful to passive smokers than to active smokers. In particular, the harm is especially serious to children. In passive smoking, many compounds are released in sidestream smoke at the higher rate than in mainstream smoke, for example, nicotine twofold, tar threefold, carbonic oxide fivefold, and carcinogens fifty-fold. The smoke that a smoker exhales also contains a lot of fine particles (PM2.5), which heavily pollute the indoor air in smoking space. Investigations show that, passive smoking is the main source of PM2.5 in indoor air in smoking places. Passive smoking contributes 90 percent of PM2.5 in an indoor environment where people smoke. As recommended by the World Health Organization (W. H. O.), the annual average concentration of PM2.5 in the air should not exceed 25 micrograms per square meter, 14 times as that in many restaurants, and 19 and 10 times as those in bars and Internet cafes, respectively.
To minimize harmful gases and particulate matters, air filters have been installed in some public places. Some of the air filters are passive with built-in filters for air purification, and the others are active for harmful gases, mainly using silver ion, negative ion, low temperature plasma, photo-catalyst, plasma cluster and other active sterilization techniques. At present, a combination of active and passive sterilization techniques is mainly used. The smoke that a smoker exhales pervades a large space. If any, it may increase the burden on the air purifier indoors. Furthermore, It takes a certain time to filter the secondhand smoke. During the time, the secondhand smoke pollution is always there, and people in such environment are inevitably poisoned by second-hand smoke. And in many public places in China, less air purifiers are installed due to the far higher cost; and, despite the smoking ban, smokers can't be completely eradicated. Other peer products give much attention to the indoor air purification, but they pay little attention to passive smoking. At present, there are some ashtray purifiers and other similar products on the market, however, they can only solve the emission of mainstream or sidestream smoke, instead of getting rid of passive smoking from the source.

When the cigarette (1) is inserted into the product, the cigarette (1) touches the detect switch (3), and the filter tip recognition module (4) automatically scans the color of the cigarette (1)(distinguishing the flammable part from the filter tip). The first motor (15) drives the rotary screw (11), the gear (24) and the blade (10) to operate. Guided by the guide gear bracket (8), the guide track bracket (13) and the guiding axle (23), the rotary screw (11), the guide gear bracket baffle (9) and the guide track bracket baffle (12) rotate by track, pushing and opening the inlet baffle (14), and inserting and clamping the cigarette (1) smoothly. When the user's mouth approaches the filter tip for smoking, the biometrics-based range sensor (PS) 2 sends an instruction to the high voltage pack (19) for arc cigarette lighter after detecting that the user's mouth is approaching, and the arc line outlet of the high voltage pack (19) for arc cigarette lighter on the clamping device (21) for the arc discharge bracket puts an arc to ignite the cigarette (1). After ignition, the cigarette lighter loosens the cigarette (1), leaves from the cigarette (1), and runs down to the bottom of the guide bracket (17). After the cigarette (1) is lit, the temperature sensor (7) detects the cigarette (1) is burnt to the filter tip, and sends an instruction to the first motor (15) to drive the rotary screw (11), the gear (24) and the blade (10) to rotate. Guided by the guide gear bracket (8), the guide track bracket (13) and the guiding axle (23), the rotary screw (11) drives the blade (10) to cut off the cigarette (1). The guide gear bracket baffle (9) and the guide track bracket baffle (12) rotate by track. The inlet baffle (14) under the elastic force of the rotary screw spring loosens the cigarette (1). After the cigarette (1) is cut off, the first motor (15) drives the rotary screw (11), the gear (24) and the blade (10) to rotate. The guide gear bracket (8), the guide track bracket (13), the guiding axle (23), the guide gear bracket baffle (9), the guide track bracket baffle (12) return by track. The rotary screw (11) drives the ashtray baffle (26) to rotate and snap, closing the cigarette ash outlet on the bottom of the ashtray (25). The product can judge the burning time of the cigarette butt in ashtray from the duration from igniting the cigarette to cutting off the cigarette and the frequency of smoking. For example, when the user keeps smoking (without breaks), the allowable smoking duration is 60 s. However, the self-burning time is 180 s without smoking. That is, the smoking duration is 3 times shorter than the self-burning time. If the smoker smokes for one minute and inhales a puff of smoke from a cigarette every 20 seconds, and 3 seconds once, and n times totally, the self-burning time of the cigarette butt is obtained by the formula {60-(3*n)}*3−20*(n−1), to the continued operation of the fan the burning time of the cigarette butt, and ensuring that all the smoke can be fully filtered before the equipment stops working.
