In today's society, the awareness of environmental protection has penetrated into the broad masses of the people. Nowadays, many products attract customers with environmental protection signs. Indeed, environmental protection is in great demand for most people who pursue the taste of life today, and the sales of environmental protection green products in the market are also relatively large. Therefore, developing green products has become the pursuit goal of scientific and technological personnel. There are few finished ashtrays that can remove smoke and few that can start automatically. Therefore, our group designed this defogging ashtray with automatic induction. This product uses MQ-2 sensor, which is popular in the market, and has good sensitivity, so the sensitivity of this product is quite good. Moreover, we adopt several layers of filtration, which decomposes the harmful substances of smoke to a great extent, and is the most ideal product for making indoor air environmentally friendly.

Design concept?

At home and in the office, because the male host smokes too much, it often causes indoor fogging, especially in winter, and poor indoor ventilation will bring harm to the health of indoor personnel. Traditional ashtrays can only contain soot, but can't absorb smoke harmful to human body and environment. Using the smoke sensor, when the smoke diffuses, the smoke sensor senses the smoke, the relay is turned to NO, the fan starts to work, the motor rotates, and the fan generates suction to suck the smoke into the filter cover filled with activated carbon and negative ions, so as to discharge fresh and clean gas, which greatly improves the indoor environment and has current environmental protection significance.
