Title:
FOAM GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/007628
Kind Code:
A1
Abstract:
Disclosed in the present invention is a foam generation device. The foam generation device comprises a foaming device, and a liquid intake pipeline, an air intake pipeline and a bubble output pipeline, which are respectively connected to the foaming device. The liquid intake pipeline comprises a water intake pipe, a Venturi pipe, a water pump and a liquid-soap box, wherein the Venturi pipe is provided with a first liquid inlet, a second liquid inlet and a liquid outlet, with the first liquid inlet being connected to the water intake pipe, and the second liquid inlet being connected to the liquid-soap box; and a water intake side of the water pump is connected to the liquid outlet, and a water output side of the water pump is connected to the foaming device. In the present invention, the Venturi pipe and the water pump are both arranged on the liquid intake pipeline. Thus, when the water intake pressure is relatively high, the suction force of the Venturi pipe on liquid soap in the liquid-soap box is increased by the same proportion; and when the water intake pressure is relatively low, the suction force of the Venturi pipe on the liquid soap in the liquid-soap box is reduced by the same proportion, such that it is ensured that the proportion of intake water to the liquid soap is controlled within a rational range, and therefore the foaming effect is effectively ensured.
