Anti-pollution spittoon isolated by utilizing foam

Abstract

The invention belongs to the field of sanitary equipment and relates to an anti-pollution spittoon isolated by utilizing foam. The invention aims at providing the anti-pollution spittoon isolated by utilizing the foam, which is capable of isolating sputum from air through the foam so as to prevent pollution. The other purpose of the invention is to cause the whole using process to be clean, sanitary, easy to clean and good in visual perception. In order to achieve the purposes, the invention is achieved by a technical scheme as follows: the anti-pollution spittoon isolated by utilizing the foam comprises a sputum collection barrel 1 and a foam barrel 2, and is characterized in that foam 10 is accumulated in the sputum collection barrel 1, and the foam barrel 2 and a foam barrel cover 13 are coated; the foam barrel cover 13 is controlled through a pedal switch 4; and the foam barrel 2 comprises a foam barrel shell 3, an inductive foam gas generator 5, a porous air outlet 6, expanding foam solution 7, a transparent liquid adding port 8, a liquid adding port cover 9, a foam channel 11, a foam vent 12, a transparent window of the barrel cover 14 and the like.

Description

technical field [0001] The invention belongs to the field of sanitary equipment and relates to an anti-pollution spittoon using foam isolation. Background technique [0002] In the prior art, the spittoon is made up of two parts, a sputum collecting bucket and a cover. Its disadvantage is that after the user opens the cover, the sputum directly contacts with the outside air, causing the spread of bacteria and viruses, polluting the surrounding environment, and endangering the health of others; at the same time, due to the viscosity of the sputum, the spittoon is not easy to be cleaned, and it is difficult to use it. The visual perception of the patient is poor. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-pollution spittoon using foam to isolate the sputum from the air to prevent pollution. [0004] Another object of the present invention is that the whole use process is clean, hygienic, easy to clean, and has good v...
