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.

Example

[0041] The first embodiment:

[0042] A foam generating device for toilets, comprising a water inlet pipe 1, an air inlet pipe 2, a foaming agent pipe 3, and a mixer 4 connected to the end of the pipe for fully mixing water, gas, and foaming agent and generating foam , The end of the mixer 4 is connected with a foam tube 5, the mixer 4 includes at least one static mixing unit, and a plurality of continuously twisted fins are arranged in the static mixing unit, so that the liquid entering the mixer 4 continuously changes the flow direction, realizing air and liquid Mix to produce fine foam.

[0043] In the embodiment, a constant pressure valve that can keep the water pressure stable is installed on the water inlet pipe 1, and a pressure adjustment switch that keeps the inlet pressure constant is installed on the inlet pipe 2.

[0044] In the embodiment, the ratio of gas to water in the gas-water mixture ranges from 1:1 to 10:1.

[0045] In the embodiment, the average bubble diameter d...

Example

[0049] The second embodiment: such as image 3 with Figure 4 As shown,

[0050] In the embodiment, the front end of the mixer is provided with a water inlet branch 6 that can periodically clean the mixer 4, and the water inlet branch 6 is provided with a solenoid valve for opening and closing the water inlet branch 6.

[0051] In the embodiment, the water inlet pipe 1 and the foaming agent pipe 3 are mixed by the first pre-mixing device 8 to form a dilute solution of the blowing agent with a lower viscosity. The dilute solution and the air in the air inlet pipe 2 pass through the second pre-mixing device. The mixing device 9 mixes to form a gas-water mixture and then enters the mixer 4.

[0052] In the embodiment, before the foam generating device for the toilet completes one foaming, the air inlet pipe 2 and the foaming agent pipe 3 stop transporting gas and foaming agent, only the water inlet pipe 1 operates, and the water flows through the first pre-mixing device 8 And the secon...

Example

[0056] The third embodiment: such as Figure 5 with Image 6 As shown,

[0057] In this embodiment, on the basis of the second embodiment, the water flow conveying pipe 7 connected from below the end outlet of the mixer 4 is set as the water flow conveying pipe 7 connected tangentially from the end outlet of the mixer 4. The water flow rushed out of the tube 7 moves forward in a spiral shape, and the foam is quickly brought out. In this way, the water flow and the foam are mixed more evenly.

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...
