Public place second-hand smoke protection device

Abstract

The invention belongs to the technical field of safety protection, and particularly relates to a public place second-hand smoke protection device. The device comprises a purification box, a cigaretteholder is fixedly connected to the outer wall of one side of the purification box, arc-shaped grooves are formed in the joint of the purification box and the cigarette holder at equal intervals, an equipartition assembly is arranged on the inner wall, close to the cigarette holder, of the purification box, the inner wall, close to the equipartition assembly, of the purification box is provided with a purification assembly, the equipartition assembly comprises two triangular guide plates, two inclined plates and a middle partition plate, the two inclined plates are fixedly connected to the inner walls of the two sides of the purification box respectively, the two triangular guide plates are fixedly connected between the two inclined plates, and the middle partition plate is fixedly connected between the two triangular guide plates. The arc-shaped groove is formed in the connecting position of the cigarette holder and the purification box, when second-hand smoke enters the purification box through the cigarette holder under the action of an exhaust fan, the arc-shaped groove is formed to prevent the second-hand smoke at the corners from impacting the inclined plates at the connectingposition of the cigarette holder and the purification box to cause rebound, and therefore the absorption rate on the second-hand smoke is increased.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a second-hand smoke protection device in public places. Background technique [0002] Second-hand smoke, also known as passive smoking and environmental tobacco smoke, refers to the mixed smoke formed by the burning end of cigarettes or other tobacco products and the tobacco smoke exhaled by smokers; it is also the most harmful and serious indoor air Pollution is a major cause of death in the world; some studies have pointed out that second-hand smoke contains more than 4,000 harmful chemicals such as tar, ammonia, nicotine, suspended particles, PM2.5, polonium-210, and dozens of carcinogens; with the increase in the number of smokers There are many smokers in public places, and in densely populated environments, the probability of second-hand smoke being reabsorbed increases sharply, causing second-hand smoke to have a great impact on human health. Therefore, it is nec...

Problems solved by technology

[0003] The existing second-hand smoke protection devices in public places have defects in use. The second-hand smoke protection devices purify and filter the second-hand smoke through the purification components inside the purification box, and absorb the harmful components in the second-hand smoke. However, the second-hand smoke from the cigarette holder Before entering the purification component inside the purification box, due to the irregular flow of second-hand smoke into the purification component, the second-hand smoke passes through the purification component messily, making the sponge filter layer, HEPA filter and No. 1 activated carbon adsorption layer on the purification component, The utilization rate of each part on the No. 2 activated carbon adsorption layer is different, which affects the overall purification effect, reduces the use value of the purification components, and increases the cleaning frequency of the purification components.
