[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0025] like Figures 1 to 5 As shown, the steam generating device described in this embodiment can be applied to steam heating equipment that requires steam, such as boiler steam output and mobile garment steamer with water storage tank; the steam generating device includes a heating tube 1; the heating tube 1 includes a tube body 11 and a thick film heating layer 12 disposed on the outer peripheral wall of the tube body 11.

[0026] It also includes a steam-water separator 2 located at the upper end of the heating tube 1 and a water inlet 3 located at the lower end of the heating tube 1; the steam-water separator 2 includes a box body 21 and a connecting pipe 22 connected to the bottom of the box body 21; the connecting pipe 22 is connected to the heating tube 1; the connecting pipe 22 is provided with a high water level probe 4 and a low water level probe 5 arranged at intervals; the box body 21 is provided with an air outlet 23, and the inner top wall of the box body 21 is provided with at least one vertically downward extending partition 24; the inner bottom surface of the box body 21 is inclined downward from the end near the air outlet 23 to the end near the connecting pipe 22; there is a gap between the partition 24 and the inner bottom surface of the box body 21.

[0027] In actual use, the steam generator of this embodiment has the heating element 1 installed vertically, and water flows from bottom to top into the pipe body 11, thus injecting water into the pipe body 11 through the water inlet 3. Both the high-level probe 4 and the low-level probe 5 are electrically connected to an external control unit. The high-level probe 4 and the low-level probe 5 are connected to the water level in the pipe 22 in real time. When the water level in the pipe 22 rises to a certain height, the high-level probe 4 generates a detection signal, and the external control unit controls the external water pump unit to stop injecting water into the pipe body 11. At this time, the thick film... When the heating layer 12 is powered on, it heats the water in the tube 11 to generate steam. The generated steam is discharged through the connecting pipe 22 and into the box 21, and then discharged from the vent 23, thus meeting the steam usage requirements. When the steam passes through the box 21, the baffle 24 blocks the water vapor in the steam. At the same time, the inner bottom surface of the box 21 is inclined, which allows the water to flow back into the connecting pipe 22 and prevents boiling water from splashing onto the vent 23, thus avoiding water vapor from coming out and making the steam discharged from the vent 23 drier.

[0028] As steam is continuously generated, the water level in the connecting pipe 22 drops. When the water level in the connecting pipe 22 drops to a certain height, the low water level probe 5 generates a detection signal, and the external control unit controls the external water pump unit to inject water into the pipe body 11, thereby replenishing the water in the pipe body 11. This cycle of replenishing water and generating steam achieves the effect of rapid steam generation, with a simpler overall structure, smaller size, and lower manufacturing cost.

[0029] It should be noted that the high water level probe 4 and the low water level probe 5 can be pulse-type water level probes, bipolar water level probes, etc.

[0030] like Figures 1 to 4 As shown, in some embodiments of the steam generator of this embodiment, the steam outlet 23 is vertically arranged on the top of the box body 21; this arrangement makes the discharged steam drier.

The box body includes a box body and a box cover fixedly disposed on the top of the box body; the partition is fixedly connected to the box cover; and the air outlet is disposed on the box cover. This embodiment uses a box body and a box cover to form a box body, facilitating the installation and production of the structure; preferably, the box cover and the box body are ultrasonically welded together, resulting in better airtightness and a more robust structure.

[0032] Preferably, such as Figure 1 and Figure 4As shown, the lid, vent, and partition are integrally molded, making assembly easier and reducing manufacturing costs. Specifically, the lid has a roughly racetrack-shaped structure.

[0033] Furthermore, such as Figure 1 and Figure 4 As shown, the lid has a receiving groove; the top periphery of the box body is embedded in the receiving groove; this design makes the connection between the lid and the box body tighter and more secure, further improving the airtightness between the two.

With this arrangement, when the generated steam enters the housing 21, the first baffle 24 blocks some of the water vapor in the steam, and the second baffle 24 blocks the remaining water vapor, thus further improving the dryness of the steam. Of course, the number of baffles 24 can also be three or four, so that water vapor is blocked sequentially by each baffle 24 to improve the dryness of the steam. The specific number can be freely set according to actual design needs.
