Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a water-liquid mixing structure for foaming and a toilet foaming device. Background Art

[0002] When using a toilet, there will be user pain points such as splashing water and dirt hanging on the wall. In order to solve this pain point, a foaming device is installed in the toilet. The foam generated in the toilet can effectively prevent splashing water and dirt hanging on the ceramic wall, and can also isolate odors, so that people can have a better user experience when using a smart toilet. At present, most toilet foaming devices on the market generally allow the foaming liquid to enter the foamer immediately after mixing with water. Since the foaming liquid and water are mixed for a short time and the mixing is uneven, the foaming effect of the foamer is not good. On the one hand, it is impossible to fully achieve the effects of preventing splashing water, preventing dirt from hanging on the ceramic wall and isolating odors. On the other hand, there is still a waste of foaming liquid. For this reason, the utility model provides a structure that can effectively improve the mixing degree of the foaming liquid to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a water-liquid mixing structure with better mixing effect.

[0004] In a first aspect, a water-liquid mixing structure for foaming is provided, comprising a water-liquid mixing component and a liquid pump.

[0005] The water-liquid mixing component includes a liquid storage chamber for storing foaming liquid, a water inlet chamber with a water inlet, and a mixing chamber. Specifically,

[0006] There are at least two mixing chambers, and the mixing chambers are connected in sequence.

The final-stage mixing chamber is provided with a liquid outlet connected to an external foamer, and is also connected to a liquid storage chamber through the liquid pump.

[0007] When started, the liquid pump transports the foaming liquid in the liquid storage chamber to the first-stage mixing chamber, and water enters the water inlet chamber through the water inlet, and then enters the first-stage mixing chamber from the water inlet chamber, and mixes with the foaming liquid in the first-stage mixing chamber, and finally is discharged outward through the liquid outlet of the final-stage mixing chamber.

[0008] To improve the mixing effect, the foaming liquid forms a swirling flow in at least one of the mixing chambers.

[0009] The water-liquid mixing structure provided by the utility model has multiple levels of mixing chambers that are connected in sequence, which can provide sufficient mixing space and mixing time for water and foaming liquid.

[0016] Preferably, the second channel is also connected to the final mixing chamber in a tangential direction, so as to further increase the speed of the rotational flow of the mixed liquid in the final mixing chamber, thereby further improving the mixing uniformity.

[0017] Preferably, the flow cross-sectional area of ​​the third channel is larger than the flow cross-sectional area of ​​the first channel and the second channel, which has the effect of saving foaming liquid, and the volume of the first-stage mixing chamber is larger than the volume of the final-stage mixing chamber. The volume of the liquid storage chamber is larger than 1.1 times the rated volume of the foaming liquid, which can prevent the foaming liquid in the liquid storage chamber from freezing and bursting the liquid storage chamber at low temperatures.
