Description

[0001] The present invention relates to an IoT-

The present invention relates to an IoT-based tobacco smoke smoke, and more particularly, to an IoT-based tobacco smoke smoke smoke monitor capable of remotely monitoring the smoke removal efficiency of a smoke smoke smoke based on IoT (Internet of Things) .

Generally, when you smoke, it can cause harmful effects to your health such as lung and cardiovascular diseases caused by toxic substances in dozens to hundreds of kinds such as carbon monoxide, acetone, naphthylamine, methanol, formaldehyde, toluidine, affect.

In particular, it is known that the influence of disease on smoking cigarettes varies depending on the type of cigarette, daily consumption, degree of inhalation, and tar content of tobacco, and smoking accounts for about 30% of all cancer deaths.

In addition, smoking is a type of second-hand smoke in which people smoke tobacco smoke that occurs when a smoker smokes, even if the smoker does not directly smokes. Thus, when secondhand smoke is given, the normal function of the cells is impaired, There is a danger to cause.

In addition, recently, it has been reported that even in the so-called tertiary cigarette smoking in a separate space, toxic substances in the cigarette smoke permeate air, furniture, and walls, affecting pregnant women and children.

As mentioned above, in order to prevent the harm of the secondhand smoke, the smoking cessation area including the public buildings is gradually expanding in Korea.

Accordingly, in recent years, a separate smoking booth for forming a smoking space has been produced and a smoking facility has been provided so that a smoker can smoke inside the smoking booth.

However, the conventional smoking booth as described above is limited only to sucking outside air by installing suction and exhaust fans in the smoking booth, and discharging the smoke inside the smoking booth to the outside, so that the health of the smoker smoking inside the smoking room There was a problem that could unnecessarily hurt even more.

Also, due to the simple structure that forced the cigarette smoke inside the cigarette booth to be exhausted to the outside, the tobacco smoke and odor are always generated around the cigarette booth, and the cigarette smoke and odor are not filtered by such factors, There is a problem that the harmful components contained in the smoke are directly exposed to the human body.

In order to solve the above problems, a regeneration utility model 20-0460041 'tobacco smoke purge exhaust system' and a registraion utility model 20-0228802 'tobacco smoke eliminator smoke' have been proposed. The commonality of the discharge device is that the carbon filter is installed inside the body provided with the suction and exhaust fan, so that the smell of the cigarette can be effectively alleviated.

In contrast, the conventional cigarette smoke purifying and discharging apparatus is only a device for purifying harmful components in the smoking booth, and various problems such as a load current applied during use or a malfunction of the purifying unit may occur, There are many cases where the manager does not reside in the place, and the problem can not be solved immediately.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide an IoT-based cigarette smoke device capable of always monitoring the state of smoke of a cigarette smoke smoke, The main purpose is to provide smoke.
