SPECIFIC EMBODIMENTS

The specific embodiments of the utility model are further described in detail below with reference to the accompanying drawings.

Embodiment 1

Referring to FIG. 1 and FIG. 7, a steam generation device includes a main body 1. A first heater 2 and a second heater 3 are respectively disposed inside the main body 1. An energy storage heating zone 4 is disposed inside the first heater 2. A first temperature controller 5 is installed inside the first heater 2. A water injection port 6 in communication with the energy storage heating zone 4 is provided on the first heater 2. A vaporization heating zone 7 is disposed inside the second heater 3. A first electric heating tube 8 and a water pipe 23 are disposed inside the vaporization heating zone 7. A steam outlet 22 of the second heater 3 is connected to a steam outlet head 9 in communication with the vaporization heating zone 7. A gas-liquid channel 10 is arranged to be in communication between the energy storage heating zone 4 and the vaporization heating zone 7.

This utility model employs a design featuring the energy storage heating zone 4 to first perform preliminary heating of water within the injection heater 2. Subsequently, after undergoing secondary heating through the vaporization heating zone 7 within the second heater 3, steam is generated. This process reduces heating time, rapidly produces steam, saves time, and is convenient to use with a short heating duration.

A battery 11 and a circuit board 12 electrically connected thereto are further respectively disposed inside the main body 1. The battery 11 provides the working power required for the circuit board 12. The circuit board 12 converts the battery power into a suitable voltage to supply various components or detect voltage, controls the operating frequency of the water pump, automatically adjusts the power of the vaporization heating zone according to the voltage, and controls its switching. Through the design of the battery, compared with steam generation devices in the prior art that require a power cord for use, the product of this technical solution can be used directly by hand after charging, free from the spatial constraints of a power cord. It is not limited by the space constraints of a power cord.

The steam generation device further includes a charging base 13. In practical use, the product can be placed on the charging base for charging and heating. When ready to use, it can be lifted and pulled out upwards for use.

A water pump 20 is disposed on the gas-liquid channel 10. A water inlet of the water pump 20 is arranged to be in communication with the energy storage heating zone 4 through the gas-liquid channel 10. A water outlet of the water pump 20 is arranged to be in communication with the vaporization heating zone 7 through the gas-liquid channel 10. In actual operation, the water pump draws the initially heated water flow from the energy storage heating zone 4 into the vaporization heating zone 7.

A pressure relief valve 16 and a check valve 17 are respectively installed on an upper end face of the first heater 2, maintaining balanced internal air pressure and effectively preventing excessive internal pressure or excessive negative pressure.

Referring to FIG. 12, the water pipe 23 can adopt a spiral design, achieving step-by-step heating of the water flow to a steam state and increasing the heating speed.

The water pipe 23 can also be designed as a grooved structure inside the vaporization heating zone sealed with a cover plate.

A second temperature controller 14 is installed inside the second heater 3 to control the temperature inside the second heater 3.

The temperature controller can be a thermostat or a temperature sensor.

Embodiment 2

Referring to FIG. 2 and FIG. 8, this embodiment is substantially identical to Embodiment 1, with the difference being that the first heater 2 and the second heater 3 employ an integrally cast design. Upon connecting to the charging base, the current divides into two paths. One path passes through a switch to enter a temperature controller, reaching the energy storage heating zone. The temperature controller starts working, causing preliminary heating of the water inside the energy storage heating zone. A pressure relief valve and a check valve are installed in the energy storage heating zone, maintaining balanced internal air pressure during operation. While operating, the energy storage heating zone also preheats the vaporization heating zone, keeping their temperatures consistent and pre-warming the vaporization heating zone in advance. Simultaneously, the other current path enters the circuit board, providing power for charging the battery. When the water in the energy storage heating zone is heated to a certain temperature, the temperature controller automatically cuts off the power, stopping the power supply to the energy storage heating zone. After disconnecting the power supply, the battery can supply power to the circuit board, and by controlling the water pump, the initially heated water inside the energy storage heating zone is drawn through the gas-liquid channel 10 to the vaporization heating zone. Furthermore, the battery supplies power to the vaporization heating zone for secondary heating. When the vaporization heating zone operates, it further increases the temperature of the energy storage heating zone, playing a role in catalyzing the energy storage heating zone. When the battery voltage is higher than a set value, the circuit board increases the operating frequency of the water pump, and vice versa. After the water flow enters the vaporization heating zone, it is heated step-by-step into a steam state through a stainless steel pipe arranged in a spiral manner or a grooved stepwise heating design, and then steam is produced through the steam outlet of the vaporization heating zone.

Embodiment 3

Referring to FIG. 3 and FIG. 9, this embodiment is substantially identical to Embodiment 2, with the difference being that other internal control components such as the water pump, the check valve, and the pressure relief valve are removed, making the structure more streamlined.

When the water flow inside the energy storage heating zone is heated to a critical value, steam is generated. Utilizing the principle of steam expansion and overflow, the steam flows upward through the gas-liquid channel 10 into the vaporization heating zone.

Embodiment 4

Referring to FIG. 4 and FIG. 10, this embodiment is substantially identical to Embodiment 3, with the difference being that the circuit board 12 and the battery are further removed, and a power connector 19, a second temperature controller 14, and a second switch 15 are added.

Power required for operation is provided by connecting the power connector 19. This embodiment has two adjustable working modes. The first working mode is as follows: the first switch 18 is first turned on to perform preliminary heating on the water inside the energy storage heating zone. When the water is heated to a critical value, steam is generated. The water vapor will then enter the vaporization heating zone through the gas-liquid channel 10. Subsequently, the second switch 15 is turned on, either simultaneously with or after the first switch 18, causing the vaporization heating zone to start operating synchronously. While the vaporization heating zone is operating, the energy storage heating zone is also working simultaneously. The temperatures of the energy storage heating zone and the vaporization heating zone influence each other, rising synchronously. Steam is then produced through the steam outlet of the vaporization heating zone.

The second working mode is as follows: the first switch 18 is turned on without turning on the second switch 15. The water inside the energy storage heating zone undergoes preliminary heating. When the heated water reaches a critical value, steam is generated. Utilizing the principle of steam expansion and overflow, the water vapor will enter the vaporization heating zone through the gas-liquid channel 10, and then steam is produced from the steam outlet of the vaporization heating zone.

Embodiment 5

Referring to FIG. 5 and FIG. 11, this embodiment is substantially identical to Embodiment 3, with the difference being that a solenoid valve 21 for controlling its opening and closing is disposed on the gas-liquid channel 10. The opening and closing of the gas-liquid channel 10 is controlled by manually operating the solenoid valve 21, or by a pressure switch in cooperation with the circuit board, or by a pressure switch controlling the solenoid valve, or by a mechanical component. The basic principles, main features, and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the aforementioned embodiments. What is described in the aforementioned embodiments and the specification only illustrates the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, all of which fall within the scope of the claimed utility model. The scope of protection claimed for the utility model is defined by the appended claims and their equivalents.
