[0036] Embodiment

[0037] The present embodiment has promoted the solution to the problem that the existing steam heater consumes a lot of shell materials and has high cost. To this end, the present embodiment provides an instant steam energy-saving heater, wherein an internal hollow mold 4 is additionally provided before the shell 3 is cast or die formed, so that the middle part of the shell 3 forms an internal hollow after the shell 3 is cast or die formed, effectively reducing the material used by the shell 3 and reducing the production cost; at the same time, the heating element 1 can heat up under the condition of being powered on, and the liquid flow assembly 2 can flow through the liquid and directly or indirectly absorb the heat of the heating element 1 through the shell 3 to generate steam.

[0038] Referring to Figure 1 and 2 , an instant steam energy-saving heater comprises at least one heating element 1, a liquid flow assembly 2, a shell 3 and an internal hollow mold 4. Among them, at least one heating element 1 can heat up under the condition of being powered on; it is to be noted that when the heating element 1 is connected to the power supply, the current passes through the resistance wire inside the heating element 1. Because the resistance wire has a certain resistance value, according to Joule's law (Q=I 2 Rt), heat will be generated when the current passes through the resistance wire. These heat is transferred to the surrounding environment or target object by conduction, convection and radiation.

[0039] Among them, the liquid flow assembly 2 can flow through the liquid and absorb the heat of at least one heating element 1, so that the liquid is vaporized into steam and discharged; for example, the liquid flow assembly 2 can be a pipe, and the liquid flows near the heating element 1, and the heat of the heating element 1 can be transferred to the liquid by conduction, convection and radiation.

[0040] Among them, at least one heating element 1 and the liquid flow assembly 2 are arranged inside the shell 3.

[0041] Among them, the mold 4 is arranged inside the shell 3, and the shell 3 is integrally formed, and the mold 4 can form an internal hollow after the shell 3 is formed as a whole.

[0042] Referring to Figure 1 and 2As shown, in some embodiments, the instant steam energy-saving heater comprises a blocking piece, the mold 4 is provided with a blocking hole 41 at least at one end, the blocking piece can be inserted into the blocking hole 41, so that when the shell 3 is integrally formed, a notch 31 adapted to the blocking piece is formed on the shell 3, and the blocking piece can be pulled out of the notch 31. For example, the blocking piece can be a wooden plug, one end of the wooden plug can be inserted into the blocking hole, the other end of the wooden plug extends out of the shell 3 and can be pulled out after the shell 3 is formed, so that the hollow area formed by the mold 4 is in communication with the outside of the shell 3 through the notch 31, effectively avoiding explosion due to internal sealing in the case of thermal expansion and contraction. For example, the mold 4 is provided with a blocking hole 41 at both ends.

[0043] Referring to Figure 3 As shown, the mold 4 is filled with a heat-conducting material 42, which can conduct the heat of the heating element 1 to the shell 3. For example, the heat-conducting material 42 can be magnesium powder, which has good heat-conducting performance and can quickly conduct the heat generated by the heating element 1 to the shell 3 and further to the liquid flow assembly 2. Such high-efficiency heat-conducting performance helps to improve the heating efficiency and avoid heat retention in the heating element 1, thereby achieving uniform heating.

Moreover, the first coil pipe 213 and the second coil pipe 214 can serve as two water inlet paths and two steam outlet paths, so as to improve the steam generation efficiency. The heating element 1 wrapped around the first coil pipe 213 and the second coil pipe 214 in a straight line or a spiral shape can fully absorb the heat emitted by the heating element 1, so as to reduce the heat loss of the heating element 1 to the outside during work, and further reduce the power consumption.
