Problems solved by technology

[0003] Existing smoke filters for second-hand smoke are filtered with environmentally friendly cotton, activated carbon and other materials, which have poor air permeability and require more effort for users to use, and some filters have poor sealability at the smoke injection inlet, and some second-hand smoke is not filtered directly. Sprays into the air, resulting in poor filtration

Abstract

The invention provides a handheld smoke filter which comprises a shell, one end of the shell is fixedly connected with a smoke spraying inlet, the other end of the shell is fixedly connected with a bottom cover, and a filter element shell for filtering smoke is arranged in the shell. The filter element shell is sequentially provided with a first sponge layer, an activated carbon filter layer, a second sponge layer and an HEPA filter from the filter element air inlet hole to the filter element air outlet hole. The handheld smoke filter can adopt sponge, activated carbon and HEPA for multiple filtering, smoke sprayed into the mouth of a user can be more effectively collected, the filtering effect is better, and the air permeability is better.

Description

technical field [0001] The invention relates to the field of air filtering devices, in particular to a hand-held smoke filter. Background technique [0002] Smoking is harmful to health. If one person in a family smokes, other members of the family will inevitably suffer from the harm of second-hand smoke. If it is frequent, non-smokers are exposed to second-hand smoke for a long time, and the injury is very prominent. Therefore, in order to prevent non-smokers from receiving the harm of second-hand smoke, it is necessary to develop a smog filter for filtering second-hand smoke. [0003] Existing smoke filters for second-hand smoke are filtered with environmentally friendly cotton, activated carbon and other materials, which have poor air permeability and require more effort for users to use, and some filters have poor sealability at the smoke injection inlet, and some second-hand smoke is not filtered directly. Sprays into the air, resulting in poor filtration. Contents...
