foam soap dispenser

Abstract

The invention discloses a foam type soap dispenser, which comprises a casing, on which a liquid storage bottle is arranged, and on which an induction control device, a power device, an extracting device and a foam making device are arranged; the extracting device includes A pressure pump with a liquid inlet and a liquid outlet, the foam-making device includes a one-way air inlet and a foam-making chamber with a nozzle; the liquid inlet of the pressure pump communicates with the liquid storage bottle, and the pressure pump The liquid outlet is connected with the foam-making chamber; a toothed screw shaft and a smooth screw shaft are arranged in the foam-making chamber, the toothed screw shaft and the pressure pump are respectively connected with the power device, and the power device Provide power. The present invention uses two screw shafts to work in combination and mix gas and liquid to produce rich and fine foam with stable foam volume, and can produce foam soap liquid with different gas content and foam volume by controlling the rotation speed of the screw shaft, so as to achieve Foam making device with controllable foam quality and foam output.

Description

technical field [0001] The invention relates to a soap dispenser. Background technique [0002] A soap dispenser is a device that can squeeze and output soap liquid for people to clean their hands and faces. It usually includes a liquid storage bottle or a liquid storage pool for storing soap liquid, and an extraction device with a nozzle for extracting the soap liquid is arranged on the liquid storage bottle or liquid storage pool. However, the old-fashioned soap dispenser that can only simply output soap liquid can no longer satisfy modern people's pursuit of a comfortable life. Therefore, the foam type soap dispenser that can make common soap liquid produce foam when outputting, becomes foam soap liquid arises at the historic moment. The common foam soap dispensers on the market today generally have these two types: one is to install a piston assembly behind the grid or mesh barrier, and the piston assembly moves to mix air and liquid and output it to the outside of the...

Problems solved by technology

The common foam soap dispensers on the market today generally have these two types: one is to install a piston assembly behind the grid or mesh barrier, and the piston assembly moves to mix air and liquid and output it to the outside of the net. This kind of mixing action plus mesh division produces foam, but the amount of foam is small, and the piston assembly is easy to get stuck and has a short life; the other is to use a combination of screws and sleeves to extract liquid and deliver it to a simple In the gear pump, the gears in the gear pump rotate to mix the air and the liquid to produce foam. However, the foam soap produced by this method has different bubble sizes and is very uneven. In this way, the liquid outlet speed will be slowed down because the soap liquid is blocked, and the foam is easy to discharge and drip from the pores, and the screw pumping device is also easy to allow the liquid to flow back, prolonging the speed of the second pumping liquid, resulting in foam volume. Unstable; plus components get stuck easily, have a short lifespan, and are prone to leaks
