Foam generation device for toilet bowl

Abstract

The invention discloses a foam generation device for a toilet bowl. The foam generation device comprises a water inlet pipe, an air inlet pipe, a foaming agent pipe and a mixing device connected to the tail end of a pipe and used for fully mixing water, air and foaming agents and generating foam. The tail end of the mixing device is connected with a foam outlet pipe. The mixing device comprises at least one static mixing unit. A plurality of continuously twisting fins are arranged in each static mixing unit so that liquid entering the mixing device can change the flow direction continuously to achieve mixing of the air and the liquid, and fine foam is generated. The foam generation device has the advantages of being capable of generating high-quality foam continuously even at quite low pressure, not prone to blockage and excellent in foam pushing capacity.

Description

technical field [0001] The invention relates to the technical field of toilets, in particular to a foam generating device for toilets. Background technique [0002] Foam is applied to toilets as a sanitation and disinfection measure to prevent odors and prevent the spread of bacteria. As the core foaming technology, there are two main methods: one is to use a material with a large number of filter holes to disperse the air-water mixture containing the foaming agent, such as figure 1 As shown; there is another way is to use the form of Venturi tube, using the sudden contraction section for air mixing, such as figure 2 Shown; Other ways also have the way that air and water containing blowing agent are mixed together, such as using a stirring motor. [0003] For the above methods, the problem of using filter materials for foaming is that they are easy to clog, especially when it is necessary to manufacture foams with small diameters, filter materials with very small porosity...

AI Technical Summary

Problems solved by technology

[0007] In addition, in the presence of low foaming agent, for the filter material, if the continuous foaming method is adopted, due to the effect of air pressure, a large amount of water containing the foaming agent will be carried out by the foam, resulting in waste.

The mixing effect is poor, so it is not a good technical solution in the continuous foaming device

Venturi-type foaming equipment is suitable for continuous foam generation, but due to the limitation of water pressure, the gas-water mixing effect is poor under low pressure, so large bubbles often appear
