Description

A vertical bubble maker

Technical Field

The invention relates to the technical field of bathroom products, and mainly to a vertical bubble maker.

Background Art

With the improvement of living standards, washing hands with hand sanitizer has become an important way of cleaning and hygiene. Hand sanitizer can clean the skin, kill bacteria and disinfect. People are becoming more and more accepting of foam-type bathroom products, and a number of foam-type automatic soap-dispensing products have emerged on the market.

Chinese patent application document CN201810767958.1 discloses a universal soap dispenser, in which a foaming cavity connected to a mixing cavity is provided above a base, and two layers of foaming nets are provided in the foaming cavity to foam a gas-liquid mixture, and the foaming cavity is horizontally arranged, which brings about a very serious problem, that is, the remaining foam after foaming can only flow back to the pipe section between the foaming net and the foaming joint or into the foaming cavity between the two foaming nets. After being placed for a period of time, the refluxed foam will slowly turn back into liquid. When foaming is produced again next time, the remaining liquid between the foaming net and the foaming joint will flow directly out of the foaming joint without passing through the foaming net, and the remaining liquid in the foaming cavity between the two foaming nets can only be discharged after passing through a layer of foaming net. In this way, the foam is discharged together with the remaining unfoamed liquid from the last time, and the foaming effect is affected.

In addition, Chinese patent CN201620152079.4 discloses a soap foamer and its foaming device, wherein the foaming chamber is arranged vertically and the foam outlet is located on the lower cover below. After each foaming, the residual foam will flow away from the foam outlet under the action of gravity and cannot flow back, resulting in a huge waste of hand soap.

With the cooperation of the umbrella-shaped push-pull member 231 and the push handle 242, each bowl-shaped body 241 is pressed and pulled back in turn to complete the liquid intake and discharge and the air intake and exhaust; the gas enters the air intake chamber 3022 of the diverter seat 31 from the air inlet 332 and flows to the pump liquid cavity 201, and the liquid enters the liquid inlet chamber 301 of the diverter seat 31 from the liquid inlet 331 and flows to the pump gas cavity 202, and then the liquid and gas are sent into the mixing chamber 4 through the outlet check valve 27. When the liquid and gas are continuously sent into the mixing chamber 4 by the diaphragm pump assembly 2, the pressure in the mixing chamber 4 increases, and the liquid and gas will be forced to flow through the reflux chamber 6 and the gas-liquid flow channel 7 in turn into the bubble making chamber 5, and are mixed through the foaming net 322 in the bubble making cavity 5 to form foam and enter the pump outlet 313.

When the motor 11 stops running, the residue that has not been eliminated flows back to the reflux chamber 6 at the bottom of the gas-liquid flow channel 7 under the action of gravity. After a period of time, the gas in the residue evaporates and the remaining pure liquid remains. When used next time, the gas-liquid mixture from the mixing chamber 4 drives the previous residual liquid to flow through the bubble making chamber 5 again, and re-foams through the foaming net 322, thereby avoiding the liquid from being discharged directly from the pump outlet 313 without passing through the foaming net 322, thereby ensuring the foaming effect and avoiding waste.
