Description

Foam machine

Technical Field

The utility model relates to a foam machine.

Background

The foaming machine, also called a foam automobile machine, adopts air pressure to compress the cleaning liquid into foam to be sprayed out, thereby preventing fine sand particles from damaging the automobile paint surface and prolonging the smoothness of the automobile paint surface. The cleaning agent is suitable for cleaning the outer walls, the glass and the floors of the automobile beauty industry, the motorcade, the buses, the trains, the airplanes and the like, and the hotels. When the air compressor is used, air compressors matched with the air compressor are selected according to different foaming machines and are used together. For example, a panda 60 type foam car washer requires a matched air compressor to reach more than 0.25 m/min. The existing foam machine comprises a steel cylinder, wherein the steel cylinder is provided with an air inlet, a mixed gas-liquid outlet and a liquid inlet, and the air inlet is connected with an air compressor; and the liquid inlet is used for adding cleaning liquid such as a cleaning agent, a liquid detergent and the like. After entering the steel cylinder, the gas delivered by the air compressor is mixed with the cleaning liquid, flows to the high-pressure spray gun from the mixed gas-liquid outlet, and sprays foam. However, since the steel cylinder is a recycled tea grower, it is necessary to add a cleaning liquid into the steel cylinder after the cleaning liquid in the steel cylinder is used up. Therefore, the pressure in the steel cylinder cannot be set too high, usually 0.25 MPa-0.28 MPa, and the pressure is small, so that the firing range of the spray gun is short, the automobile effect is poor, and the automobile washing is inconvenient. Meanwhile, the pressure is low, the foam is coarse and uneven, so that the water consumption is high, and water is not saved. In addition, because the cleaning solution is usually corrosive, the steel cylinder is easy to rust after long-term use, and therefore rust removal is often needed. In addition, the bottom of the steel cylinder is stored with cleaning liquid for a long time, and after corrosion, the bearing pressure in the steel cylinder is reduced, so that the steel cylinder is easy to explode. Therefore, it is necessary to design a foaming machine which is safe to use and has good foaming effect.
