Description

Technical Field

[0001] The invention relates to the technical field of bathroom devices, and in particular to an adjustable foam generating component. Background Art

[0002] Users often use cleaning liquid when cleaning. However, in actual use, the ratio of cleaning liquid to clean water is difficult to control manually. For example, too much cleaning liquid will lead to waste; too little cleaning liquid will lead to poor cleaning effect. It is difficult to achieve a balance.

[0003] In order to solve the above problems, the market has gradually begun to use foam generators to replace traditional cleaning fluids. The foam generator can automatically mix the cleaning fluid and air in a suitable proportion, and then discharge the foam, which ensures the cleaning effect and avoids the problem of waste of cleaning fluid. The existing foam generators are basically powered by electric motors. The motor is powered by batteries to drive the output shaft to rotate, and the output shaft drives the foamer to rotate, mix the cleaning fluid and air in a suitable proportion, and then discharge the foam. However, the use of electric motors means that a series of components such as batteries and circuit boards are required, which is not only costly, but also the batteries will cause environmental pollution and energy consumption, which does not meet the requirements of green environmental protection. Summary of the invention

[0004] The purpose of the present invention is to provide an adjustable foam generating component which does not require batteries as power, is energy-saving and environmentally friendly, has low manufacturing cost, and is easy to use.

[0005] To solve the above problems, the present invention provides an adjustable foam generating component, including a liquid supply pipe, a switch component, a shell, a rotating shaft, an impeller and a foamer, wherein the liquid supply pipe has a branching area branching into a first flow channel and a second flow channel, the switch component acts on the liquid supply pipe and controls the water flow to flow through the first flow channel or the second flow channel, the shell is connected to the liquid supply pipe, the shell has an inner cavity and one side of the shell is provided with a mounting hole for rotatable connection of the rotating shaft, the rotating shaft includes a first end located in the second flow channel and a second end located in the inner cavity, the impeller is connected to the first end of the rotating shaft, the foamer is connected to the second end of the rotating shaft, the shell is provided with an air inlet, a liquid inlet and a foaming outlet all connected to the inner cavity, the impeller is driven to rotate by the water flow in the second flow channel, and when the impeller rotates, the foamer is driven to rotate through the rotating shaft, so that the foamer sucks in the medium from the air inlet and the liquid inlet and squeezes the medium toward the foaming outlet after mixing.

[0006] In the above scheme, the liquid supply pipe can be installed at the water outlet of the bathroom faucet, or the liquid supply pipe can be directly used as a water pipe for bathroom equipment such as shower heads. By default, the switch component controls the water flow flowing into the liquid supply pipe to flow only through the first flow channel. When foam needs to be generated, the switch component controls the water flow flowing into the liquid supply pipe to flow through the second channel. At this time, the impeller rotates and drives the foamer to rotate through the rotating shaft, so that the foamer sucks the medium from the air inlet and the liquid inlet and mixes them and then squeezes them toward the bubble outlet, thereby achieving foam generation without battery power supply, effectively achieving the effect of energy saving and emission reduction, and having low manufacturing cost and good practicality. At the same time, after the water flows out of the second channel, it can still flow out from the end of the liquid supply pipe and be used normally, without causing any impact, and whether foam is generated can be controlled by adjusting the switch component, and the operation is simple.

[0007] In an improved scheme, the first flow channel and the second flow channel have inlets adjacent to each other, and the positions of the liquid supply tube corresponding to the inlets of the first flow channel and the second flow channel are provided with adjustment holes along the radial direction of the liquid supply tube, and the switch member is slidably inserted in the adjustment hole, and the switch member includes a button portion located outside the liquid supply tube and a switching portion located inside the liquid supply tube, and the switching portion has a flow hole along the axial direction of the liquid supply tube. The switch member moves in the adjustment hole to control the flow hole to be respectively connected to the inlet of the first flow channel or the second flow channel, so that the connection state between the adjustment hole and the inlet of the first flow channel or the second flow channel can be switched by pushing and pulling the button portion of the switch member, which is convenient to use.

[0008] In an improved solution, a shower head is connected to the end of the liquid supply pipe in the direction of water flow, the diversion area is located in the middle of the liquid supply pipe, and the shell is located at the position of the diversion area, so that when the user uses the shower head, by adjusting the switch part, it is possible to control at any time whether the bubble outlet will discharge foam.

[0009] In an improved solution, a shower head is connected to the end of the liquid supply pipe in the water flow direction, the diversion area is located at the end of the liquid supply pipe, the shell is located inside the shower head, and the shower head is provided with a water spray hole connecting the first flow channel and the second flow channel, and a bubble spray hole connecting the bubble outlet, so that when the user uses the shower head, by adjusting the switch component, it is possible to control at any time whether the bubble outlet will discharge foam to the bubble spray hole.

[0011] In an improved solution, the foamer is a diaphragm pump, a gear pump, or a screw pump.

[0012] In an improved scheme, the foamer is a diaphragm pump, which includes an eccentric wheel, and a first one-way membrane, a second one-way membrane and a third one-way membrane, all of which are bowl-shaped. The eccentric wheel is connected to the second end of the rotating shaft, the first one-way membrane is connected to the inner side of the air inlet, the second one-way membrane is connected to the inner side of the liquid inlet, and the third one-way membrane is connected to the inner side of the bubble outlet.

The convex parts of the first one-way membrane, the second one-way membrane and the third one-way membrane are all facing the eccentric wheel. The eccentric wheel drives the first one-way membrane, the second one-way membrane and the third one-way membrane to deform by rotating, so that the gas at the air inlet and the cleaning liquid at the liquid inlet enter the inner cavity through the first one-way membrane and the second one-way membrane respectively and mix into foam, and the foam is then discharged from the bubble outlet through the third one-way membrane.

[0013] In an improved scheme, the foamer is a gear pump, which includes a gear connected to the second end of the rotating shaft, the air inlet and the liquid inlet are both opened in the upper part of the shell, the bubble outlet is opened in the lower part of the shell, and the air inlet, the liquid inlet and the bubble outlet are all facing the outer circumference of the gear, the inner cavity is cylindrical and coaxial with the gear, the tooth gap on the outer circumference of the gear is in contact with the inner circumferential wall of the inner cavity, and the gear rotates so that the gas at the air inlet and the cleaning liquid at the liquid inlet enter the inner cavity and mix into foam, and the foam is then discharged from the bubble outlet.
