Abstract

The invention relates to a foam generator which mainly adopts a centrifugal blower or an axial-flow blower for providing air flow with a suitable speed; a foaming net is a mesh plate which is full of holes with micro diameters; aqueous solution added with a surfactant is poured onto the mesh plate under the action of the pressure; the aqueous solution and the air blown out by the blower are sufficiently combined on the mesh plate to form a great amount of air foams; then the air foams are cut by a foam cutting device to form rich and exquisite air foams; and the rich and exquisite air foams flow out through a foam outlet.

Description

A kind of foam maker

Technical field:

This is aly to be used for making abundant specially and the foam maker of exquisiteness and the uniform air of speed.

Background technology:

People know in the actual life: foam maker is made air and is sprayed on the toilet water surface, makes to cover certain thickness foam on the water surface and can play the effect with the stink diffusion that splashes that prevents addle.At present, relevant foam maker mainly injects the compressed air of the aqueous solution that has added surfactant and air compressor output in the container, makes the air and the aqueous solution fully mix the back under the mechanism and produces foam.Because complex structure, volume and weight is all bigger, and noise is also very big, can not be convenient to use.

Summary of the invention:

In order to overcome above-mentioned foam maker complex structure, the shortcoming of aspect such as volume and weight is excessive, and noise is also big; Be used in combination the quantity of the required foam of toilet, the invention provides a kind of foam maker, it is simple in structure; Light and handy practical, basic noise-less pollution, and the efficient of generation foam is higher.

The technical solution adopted for the present invention to solve the technical problems is: pack into container and contain the aqueous solution of proper amount of surfactant; Micromachine is as the power source of axial-flow type or cfentrifugal blower; At air outlet plastics or wire lath are installed; The aperture of net should be small, and the diameter in hole is installed a foam cutter sweep in 1.3 millimeter behind the net sheet.The aqueous solution is annotated on the wire side through the water pipe pressure, and fan blows out the air stream of speed about 10 meters of per seconds to wire side, after the pore that the air via hole diameter is very little flows out; With near the aperture interpolation the aqueous solution of surfactant fully combine, can on wire side, generate a large amount of airs, but the single volume of foam of this moment is bigger; Pass through the dissection of foam cutter sweep again; Just become the small air to 2 millimeter in aperture, generated in the process of foam on the foam screen, the flow velocity of air is very fast; Can take away a large amount of not by the expanding foam solution of foamed; Foam cutter sweep and foam screen combine very tight, make that remaining expanding foam solution engages the generation foam once more on the foam screen with air in the process of cutting, and the utilization ratio of expanding foam solution is higher.

The invention has the beneficial effects as follows: product structure is simple, and volume is little, light weight, and light and handy and easy operating, the foam of generation is abundant and fine and smooth, and blebbing speed is even, and the utilization ratio of expanding foam solution is higher.

Description of drawings:

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

One: 1 bubble output hole of figure, 2 foam cutter sweeps, 3 spread all over the web plate of aperture, 4 DC micromotors, 5 blower fan blades, 6 air inlet ports, 7 shells, 8 connect power cable, 9 water inlets, 10 machine shafts.

Two: 1 cutter sweeps of figure, 2 spread all over the web plate of aperture, 3 water filling ports, 4 blower fan blades, 5 and 11 DC micromotors, 6 blower drums, 7 peristaltic pumps, 8 outlet pipes, 9 water inlet pipes, 10,12 motor electric wires, 13 bubble output holes, 14, air inlet port.

The specific embodiment one:

After connecting DC micromotors 4 through power cable 8, motor rotation axis 10 makes fan blade 5 and foam cutter sweep 2 rotate with suitable speed simultaneously, air through air inlet port 6 under the effect of electric motor fan blade; Formation speed blows to web plate with holes 3 at the air stream of about 10 meters of per seconds; The diameter of aperture is 1.3 millimeter on the web plate, and the aqueous solution that has added surfactant flows on the web plate through water inlet 9 under the effect of pressure, and the flow of the aqueous solution is about 5 milliliters of per seconds; The air and the aqueous solution fully combine on web plate; Just formed air, the single volume of foam that form this moment is bigger, the foam cutter sweep of flowing through and rotating; Be cut into countless tiny airs, be injected in the toilet through bubble output hole 1.

The specific embodiment two:

After connecting electric wire 10 and 12, DC micromotor 11 drives foam cutter sweep 1 and rotates, and DC micromotor 5 drives peristaltic pump 7 simultaneously and rotates with fan blade 4; To foam screen 2 aqueous solution that has added surfactant is provided through outlet pipe 8 and water filling port 3 with constant flow (approximately per second is about 5 milliliters) from water inlet pipe 9 peristaltic pumps, air sucks through air inlet port 14, and the air stream that blast fan blows out is about 10 meters of per seconds; Air is flowed through after the aperture of foaming web plate flows out; The aqueous solution with the belt surface activating agent on web plate fully combines, and forms foam, the foam cutter sweep of flowing through; Be cut into countless tiny airs, inject toilet through bubble output hole 13.

Claims

1. froth foam generator is made up of air inlet port, centrifugal or axial blower, foam screen, water inlet, shell etc., It is characterized in that:By centrifugal or axial blower the air stream of speed about 10 meters of per seconds is provided; Foam screen is the web plate that is covered with aperture; A foam cutter sweep is installed in 1.3 millimeter in the aperture between foam screen and bubble output hole, the aqueous solution and the air that have added surfactant are fully combined on web plate; After having formed the bigger air of single volume, be cut into the small fine and smooth air of countless volumes when flowing through the foam cutter sweep.
