Title:
BOTTOM-MOUNTED LARGE-CAPACITY SINGLE-AIR PUMP FOAM GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/082041
Kind Code:
A1
Abstract:
A bottom-mounted large-capacity single-air pump foam generating device, comprising: a liquid supplementing mechanism and a foam generating mechanism; the liquid supplementing mechanism comprises a liquid supplementing tank (100) and a liquid supplementing bottle (200). The bottle opening of the liquid supplementing bottle (200) is sleeved in the liquid supplementing tank (100). The foam-generating mechanism comprises an air supply pump unit, an air mixing tank cavity (300), an air-liquid mixing structure, an air inlet (310) and a ventilation valve structure (320). A lower portion of the air mixing tank cavity (300) communicates with a lower portion of the liquid supplementing tank (100). A liquid supplementing one-way valve (400) is provided between the air mixing tank cavity (300) and the liquid supplementing tank (100). The air-liquid mixing structure is provided with a liquid discharge channel (330), an air discharge channel (340) and a mixing channel (350). An inlet end of the liquid discharge channel (330) extends down into the bottom of the air mixing tank cavity (300). An inlet end of the air discharge channel (340) and the air inlet (310) both communicate with an upper portion of the air mixing tank cavity (300). An outlet end of the liquid discharge channel (330) and an outlet end of the air discharge channel (340) each communicate with the inlet of the mixing channel (350). Automatic liquid supply and liquid supplementation can, by means of a mechanical structure, be achieved between the liquid supplementing bottle (200), the liquid supplementing tank (100) and the air mixing tank cavity (300) of the device, thus large-capacity use is achieved, and liquid supplementation does not need to be frequently carried out.
