Specific examples are as follows:

Please refer to FIGS. 1 to 3 , a detachable external cigarette filter with waterproof and breathable membrane, including a filter 1 for smoking cigarette smoke, and a left end sleeved on the filter 1. The waterproof sleeve 2 on the outer side, the suction unit 3 sealed with the right end of the waterproof sleeve 2, the right end of the suction unit 3 is provided with a suction nozzle 4 for sucking smoke, The inside of the waterproof sleeve 2 is provided with a first waterproof and breathable module 5 on the side close to the filter 1, and the suction unit 3 is provided with a second waterproof and breathable module 6 on the side close to the suction nozzle 4. The first waterproof and breathable module 5, the waterproof sleeve 2, the suction unit 3 and the second waterproof and breathable module 6 together constitute a sealed and breathable accommodation cavity, and the accommodation cavity is filled with water-based fragrance. aqueous solution.

In this embodiment, the left end of the waterproof sleeve 2 is sleeved on the outside of the filter 1 , and the right end of the waterproof sleeve 2 is in sealed communication with the suction unit 3 , so the suction nozzle 4 can The filter tip 1 is used for smoking, and the smoke generated by the burning of the cigarette needs to enter the suction nozzle 4 through the accommodating cavity. Since the accommodating cavity contains an aqueous solution of water-based fragrance, the aqueous solution can intercept The harmful substances in the smoke are easily soluble in water, and at the same time, the flavors and fragrances in the aqueous solution will enter the suction mouth 4 along with the smoke, thereby improving the smoking taste of the cigarette.

In this embodiment, the first waterproof and breathable module 5 is an organic material or a ceramic material. The second waterproof and breathable module 6 is made of organic material or ceramic material, which is non-toxic and harmless, has good ventilation effect, and the ceramic material or organic material will not change due to heat.

Since the aqueous solution in the container is in a static state, during the continuous suction process, the aqueous solution may absorb more and more harmful substances, resulting in the contamination of the aqueous solution. Therefore, the aqueous solution in the container needs to be removed after suction. Replace it with a new, clean water solution to ensure the best feeling for the next puff.

Therefore, in this embodiment, the right end of the waterproof sleeve 2 is sealed and inserted into the left end of the suction unit 3 . The direct plug-in structure is simple and easy to disassemble.
