In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 3, a first aspect of the present invention provides a mixing device 1000, wherein the mixing device 1000 is used in a water heater and includes a mixing tank 100, a water inlet pipe 200 and a water outlet pipe 300. The interior of the mixing tank 100 has a mixing chamber 101, and both the inlet conduit 200 and the outlet conduit 300 are at least partially located within the mixing chamber 101.

Wherein the inlet pipe 200 includes a first pipe 210 and a dividing plate 220, the first pipe 210 includes a first inlet located outside the mixing tank 100 and a first outlet located inside the mixing tank 100, and the dividing plate 220 is disposed at the first outlet.

In the existing mixing device 1000, the water inlet pipeline and the water outlet pipeline are generally directly connected to the surface of the tank body and do not extend into the mixing tank 100, so that insufficient gas-liquid mixing is caused, and the generation of micro-nano bubble water is influenced.

Through adopting above technical scheme, inlet channel 200 and outlet conduit 300 all are partly located mixing chamber 101 at least for the gas-liquid mixture water that gets into from inlet channel 200 can mix in blending tank 100 fully, sets up the partition plate 220 that is used for cutting apart the bubble simultaneously in the first exit of inlet channel 200, makes the final gas-liquid mixture water of discharging through outlet conduit 300 be the higher micro-nano bubble water of micro-nano bubble content.

It can be understood that the mixing device 1000 is arranged at the water outlet end of the water heater, water in the heating device is stored in the mixing tank 100 and fully mixed with cold water for cooling after the water heater is stopped, meanwhile, cold water after the water heater is restarted can enter the mixing tank 100 for fully mixing and heating, so that the problems of water outlet water stop temperature rise and water outlet water temperature rise suddenly after the water heater is stopped and restarted are solved, and the mixing device 1000 plays a water mixing role only at the moment. Referring to fig. 3, 4 and 7, in an alternative embodiment, the dividing plate 220 includes a plurality of through holes 221 spaced apart from each other. Specifically, the diameter of the through hole 221 ranges from 0.2 mm to 2.0 mm, such as 0.2 mm, 1.0 mm, or 2.0 mm. It can be understood that the through hole 221 is used for water and bubbles in the gas-liquid mixed water to pass through, and the through hole 221 in the diameter range can effectively divide the bubbles in the gas-liquid mixed water, so that the radius of the bubbles in the water flowing out from the water inlet pipe becomes smaller, and the content of the micro-nano bubbles is improved. The diameter of the through hole 221 is too large, so that the effect of generating micro-nano bubbles by cutting bubbles cannot be achieved; if the diameter of the through-hole 221 is too small, the flow of the gas-liquid mixed water in the water inlet pipe is affected.

It can be understood that the filter screen structure is arranged in the water inlet pipeline 200 and/or in the pipeline before the water inlet pipeline 200, and by arranging the filter screen structure, solid impurities contained in the inlet water can be filtered at the water inlet end, so that the solid impurities are prevented from entering the mixing device 1000 and affecting the performance of the mixing device 1000.

Specifically, the thickness of the dividing plate 220 ranges from 0.2 mm to 2.0 mm, such as 0.2 mm, 1.0 mm, or 2.0 mm. It can be understood that the excessive thickness of the dividing plate 220 may affect the installation of the dividing plate 220 and the water inlet pipe; the mechanical strength of the dividing plate 220 is affected by the excessively thin thickness of the dividing plate 220.

Referring to fig. 7, in an alternative embodiment, a plurality of through holes 221 are distributed on the partition plate 220 in an array. Illustratively, the plurality of through holes 221 are uniformly distributed in a polygonal array, such as a regular hexagon or a regular octagon. It can be understood that the uniform distribution of the through holes 221 in the polygonal array can make the water flow passing through the partition plate 220 more uniform, and prevent the turbulence and the like from affecting the flow rate of the water flow in the water inlet pipe. Of course, the arrangement of the plurality of through holes 221 may have other shapes, and the closer to the shape of the cross-sectional profile of the first pipe 210, the more uniform the water flow in the first pipe 210.

Referring to fig. 1, 3 and 6, in an alternative embodiment, the mixing tank 100 includes a housing 110 and a first end cap 120 and a second end cap 130 mounted on opposite ends of the housing 110, a water inlet pipe 200 connected to the first end cap 120, and a water outlet pipe 300 connected to the second end cap 130.

It can be understood that the water inlet pipe 200 and the water outlet pipe 300 may also be disposed on the same end cover, which may ensure that the micro-nano bubble content of the micro-nano bubble water discharged from the water outlet pipe 300 is within a preset range after the gas-liquid mixed water flowing into the mixing tank 100 from the water inlet pipe 200 is sufficiently mixed, and the present invention is not limited thereto.

Referring to fig. 2 and 3, in an alternative embodiment, the first end cap 120 is provided with a first connection hole 121, and the water inlet pipe 200 is inserted into the mixing chamber 101 through the first connection hole 121.

Illustratively, the strainer 320 is provided with a plurality of strainer holes 321, which can further filter the gas-liquid mixture water in the mixing tank 100.

Referring to fig. 7 and 8, the structure of the filter screen 320 is similar to that of the partition plate 220, and a plurality of filter holes 321 are formed in the filter screen 320. Specifically, in the case that the number and distribution of the filtering holes 321 in the filtering net 320 are similar to the number and distribution of the through holes 221 in the partition plate 220, the diameter of the filtering holes 321 is smaller than that of the through holes 221, so that the pressure in the mixing tank 100 is increased, and the flow rate of the water in the outlet pipe 300 is increased.

Referring to fig. 4, in an alternative embodiment, the water inlet pipe 200 includes a first pipe 210 and a dividing plate 220, the dividing plate 220 is installed at one end of the first pipe 210, and the other end of the first pipe 210 is provided with a first connection part for connecting with an external component. Referring to fig. 5, in an alternative embodiment, the water inlet pipe 200 includes a second pipe 310 and a filter screen 320, the filter screen 320 is installed at one end of the second pipe 310, and a second connection portion is provided at the other end of the second pipe 310 for connecting with an external component. It will be appreciated that in a particular embodiment, the first tube 210 is identical in construction to the second tube 310.
