The weight increase of the scale inhibition module 300 is further realized while the strength of the connecting pipe body 322 is strengthened, so that the scale inhibition module 300 can better stabilize the water outlet pipe 210, and the situation that the water outlet pipe 210 shakes due to water flow fluctuation is avoided.

Further, a partial area of the inner housing 311 is recessed toward the outer housing 312 to form a partial avoiding groove 330, and another partial avoiding groove 330 is formed on the connecting tube 322.

In some embodiments, as shown in fig. 6 and 7, the inner container 100 includes a first inner container 100A and a second inner container 100B that are independent from each other, the first inner container 100A and the second inner container 100B are respectively provided with a water inlet structure, a water outlet structure and a heating pipe, and the water outlet structure 200A of the first inner container 100A is communicated with the water inlet structure 400B of the second inner container 100B through a connecting pipe 500.

In detail, the water inlet of the water inlet structure 400A is suitable for being communicated with an external water inlet pipeline 800, the water outlet of the water inlet structure 400A and the water inlet of the water outlet structure 200A are located in the first liner 100A, the water outlet of the water outlet structure 200A and the water inlet of the water inlet structure 400B are communicated through the connecting pipe 500, the water outlet of the water inlet structure 400B and the water inlet of the water outlet structure 200B are located in the second liner 100B, and the water outlet of the water outlet structure 200B is communicated with the external water outlet pipeline 900, so that the external water inlet pipeline 800 firstly feeds water into the first liner 100A, and when the first liner 100A feeds water to a certain degree, the water further feeds water into the second liner 100B through the communicating pipe.

Further, the first and second inner containers 100A and 100B are respectively provided with a magnesium rod 600.

The embodiment provides a water heater 10 with double inner containers, wherein the two inner containers are mutually independent, and each of the two inner containers is provided with a water inlet structure, a water outlet structure and a heating pipe. The water in the inner containers can be heated by respectively controlling the heating pipes of the two inner containers, so that under the condition of the same overall volume, the capacity of the first inner container 100A and the capacity of the second inner container 100B are smaller than that of the integral inner containers in the prior art, and when a user washes the face, washes vegetables and the like with a small amount of water, the water in the second inner container 100B can be heated only, after the water is used, the residual hot water in the second inner container 100B is relatively less, the utilization rate of the hot water is improved, and the waste is avoided. Meanwhile, the water required to be heated of each heating pipe is smaller, so that the heating efficiency and the heating speed of each heating pipe are improved.

In one embodiment, the water inlet structure 400A, the water inlet structure 400B, the water outlet structure 200A, and the water outlet structure 200B are integrated on the heating tube, or a part of the heating tube forms the water inlet structure 400A, the water inlet structure 400B, the water outlet structure 200A, and the water outlet structure 200B, so that the heating tube 700 has the functions of heating, water inlet, and water outlet, and the number of holes formed in the inner container 100 is further reduced.

In more detail, the first inner container 100A is located below the second inner container 100B, the water outlet of the water inlet structure 400A is located at the bottom of the first inner container 100A, and the water outlet of the water inlet structure 400B is located at the bottom of the second inner container 100B, so that the amount of the retained water at the bottom walls of the first inner container 100A and the second inner container 100B is reduced. The heating pipe 700A is located at the bottom of the first inner container 100A, and the heating pipe 700B is located at the bottom of the second inner container 100B, which is beneficial to directly adding water to the bottom of the inner container 100. The water inlet of the water outlet structure 200A is located at the top of the first inner container 100A, and the water inlet of the water outlet structure 200B is located at the top of the second inner container 100B, so that when a user uses a large amount of water, the heating pipe 700A and the heating pipe 700B work simultaneously, the heating pipe 700A heats the water at the bottom of the first inner container 100A, the heated water flow rises to the upper portion of the first inner container 100A, and thus the water flowing into the second inner container 100B from the first inner container 100A is hot (warm) water, so that the problem that the cold water in the first inner container 100A flows into the second inner container 100B in a mixed manner is avoided, and the hot (warm) water from the first inner container 100A is further heated by the heating pipe 700B and then continues to rise to the top of the second inner container 100B, and finally is discharged from the water outlet structure 200B. Because the water discharged into the second inner container 100B from the first inner container 100A is already heated by the heating pipe 700A at the beginning, the temperature is higher, the water in the second inner container 100B is easier to heat up, the heating efficiency is higher, the heating speed is faster, and the hot water discharging time of the product is shortened.

In some embodiments, the first inner container 100A and the second inner container 100B are respectively provided with the scale inhibition module 300 therein. Thus effectively ensuring the scale inhibition effect of the two inner containers 100.

The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, but the present invention is not limited to the above embodiments, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the technical scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still belong to the scope of the present invention.
