Firstly, a float valve 41 can be installed inside the water tank 4, a water inlet of the float valve 41 is connected with a tap water pipe, and when the water level in the water tank 4 is lower than the set water level of the float valve 41, tap water enters the water tank 4; as the water level in the tank 4 rises, the float on the float valve 41 also rises, and when the water level rises to a certain level, the float valve 41 closes. In some embodiments, there are two water tanks 4, wherein one water tank 4 may be on standby.

The water level gauge 52 may be used to detect the water level in the gas tank 5, the water level in the gas tank 5 being mainly below the steam-water separation diaphragm 51; when the water level in the gas tank 5 is lower than the preset water level, the water pump 3 works, the water pump 3 pumps the water in the water tank 4 into the heating tank 2, the electric heating rod 21 is electrified to heat the water in the heating tank 2 to boiling, and the water vapor generated by heating is finally gathered in the gas tank 5 and is left on the upper part of the gas tank 5; wherein, catch water 53 is installed at the top of gas pitcher 5, can be in catch water 53 external ball valve.

Example 2

If the output of water pump 3 directly stretches into the inside of heating jar 2, a strand of rivers of its output, difficult rapid heating in the short time, this can lead to local temperature of water to hang down, influences holistic heating effect. As shown in fig. 1 to 7, as shown in fig. 3, 4, 5, 6, and 8, a transverse water inlet pipe 32 is further disposed inside the heating tank 2, the transverse water inlet pipe 32 and the heating tank 2 are coaxially disposed, a connecting pipe 31 is disposed between the transverse water inlet pipe 32 and an output end of the water pump 3, one end of the connecting pipe 31 is communicated with the output end of the water pump 3, and a first mounting hole communicated with the other end of the connecting pipe 31 is disposed in the middle of the transverse water inlet pipe 32; the lateral wall of the transverse inlet pipe 32 is provided with a plurality of second through holes 321.

Firstly, water output by the water pump 3 sequentially passes through the connecting pipe 31 and the transverse water inlet pipe 32 and then is emitted to the inside of the heating tank 2 from the second through hole 321 on the side wall of the transverse water inlet pipe 32; when the cold water that jets out in second through-hole 321 department mixes with the hot water in the heating tank 2, the position and the structure of horizontal inlet tube 32, in addition the setting of second through-hole 321 for carry to the water in the heating tank 2, the water distribution is even, and cold water can with hot water flash mixed, thereby effectively improves heating efficiency.

In some embodiments, a check valve may be provided between the output end of the water pump 3 and the connection pipe 31 in order to prevent the reverse flow.

In some embodiments, to facilitate machining and maximize hole area; the second through hole 321 is circular.

Example 3

The electric heating rods 21 are provided with three groups, and the three groups of electric heating rods 21 are symmetrically arranged outside the transverse water inlet pipe 32. In this way, the electric heating rod 21 can rapidly heat the water near the lateral water inlet pipe 32.

In some embodiments, to improve the heat dissipation effect, the side wall of the housing 1 is provided with a plurality of heat dissipation holes 11.

Example 4

In practical studies, it has been found that the water droplets at the inner wall of the gas tank 5 are larger in volume, and the closer to the space of the inner wall of the gas tank 5, the larger the volume of the water droplets.

If the first through holes 513 are arranged on the plate surface of the steam-water separation partition plate 51 in a disordered manner and all the first through holes 513 have the same size, as in embodiment 1.

The core of this embodiment is that, the closer to the edge of the steam-water separation partition plate 51 (i.e., the closer to the inner wall of the gas tank 5), even if the first through hole 513 is blocked by the liquefied water droplets at the bottom of the steam-water separation partition plate 51, the larger the diameter of the first through hole 513, the easier it is to ventilate again at the first through hole 513 having a larger diameter. With the concentric circle arrangement, the number of the first through holes 513 can be increased to the maximum.

Example 5

The side wall of the transverse water inlet pipe 32 is further provided with a plurality of groups of second through hole groups 321m which are spirally distributed, and each second through hole group 321m is composed of a plurality of second through holes 321; the second through holes 321 in the two adjacent sets of second through holes 321m are arranged in a staggered manner.
