As shown in fig. 3, an insulating layer 207 is provided on the outer side surface of the liner 201 of the present embodiment for reducing heat loss of the liner 201. The heating device includes a coil 205, the coil 205 is sleeved on the outer peripheral surface of the heat insulation layer 207, a magnetic field generated by energizing the coil 205 passes through the liner 201, and an induced current is generated inside the liner 201 because the liner 201 is made of a metal material, so that heat is generated to heat water in the liner cavity 201 a. The top of the liner 201 is provided with a steam outlet 206, and the steam outlet 206 is communicated with the liner cavity 201a, so that steam in the liner cavity 201a can be transmitted outwards.

With continued reference to fig. 2, a metal graphite gasket 212 is disposed between the first flange 202 and the second flange 203. In the process of connection between the first flange 202 and the second flange 203, the first flange 202 and the second flange 203 are continuously adjacent to each other, at this time, the metal graphite gasket 212 is pressed by the first flange 202 and the second flange 203 to be elastically deformed, and the metal graphite gasket 212 is respectively and tightly attached to the first flange 202 and the second flange 203 under the action of elastic restoring force, so that the gap between the first flange 202 and the second flange 203 is reduced, and the air tightness of the steam generating device 200 is improved.

With continued reference to fig. 2, in this embodiment, a fixing plate 211 is provided on a side of the first flange 202 facing the liner 201. The inner container 201 of the present embodiment can establish a fixed connection relationship with the mounting rack through the fixing plate 211, so as to be beneficial to improving the connection stability between the steam generating device 200 and the host 100.

With continued reference to fig. 2, in this embodiment, a relief valve 213 and a negative pressure valve 214 are further provided on the top outer side of the liner 201, and the relief valve 213 and the negative pressure valve 214 are respectively in communication with the liner chamber 201 a. When the air pressure in the liner chamber 201a is excessively high, the excess steam can be discharged through the relief valve 213. When the air pressure in the inner container cavity 201a is too low due to rapid temperature decrease in the inner container cavity 201a, air is injected into the inner container cavity 201a through the negative pressure valve 214 to keep the air pressure balance in the inner container cavity 201 a.

With continued reference to fig. 2, in this embodiment, an exhaust port 215 is also provided, the exhaust port 215 being in communication with the liner chamber 201 a. The air in the liner chamber 201a can be pumped out through the air outlet 215, so that water can be injected into the liner chamber 201a more easily.

With continued reference to fig. 3, a first water level detector 208 and a second water level detector 209 are provided on top of the liner 201. The first water level detector 208 is for detecting a high water level. The second water level detector 209 is for detecting a low water level. It should be noted that the level of the water in the liner chamber 201a is determined according to the actual situation, and the above-mentioned high water level and low water level are only relative. Illustratively, in the present embodiment, when the second water level detector 209 is triggered, heating may be started while the water injection process is continued, so that the heating time can be shortened. The water filling is stopped when the first water level detector 208 is triggered. Alternatively, the first and second water level detectors 208 and 209 of the present embodiment are pulse type water level detectors.

With continued reference to fig. 3, a protective tube 210 is further disposed on the top inner surface of the liner 201, the protective tube 210 extends toward the bottom of the liner 201, and a space is provided between the bottom of the protective tube 210 and the bottom of the liner 201, so that the lumen of the protective tube 210 communicates with the liner lumen 201 a.

The heating in this embodiment is performed by the coil 205, and therefore the side wall of the liner 201, which is directed to the coil 205, is the actual heating source, so the boiling of water starts from the side wall of the liner 201. After the protective tube 210 is provided, since the protective tube 210 partitions a part of the space in the inner container cavity 201a, a part of water is located in the lumen of the protective tube 210 after water is injected. When the water is boiled, since the protection tube 210 can block the fluctuation of the water starting from the sidewall of the liner 201 and the wall of the protection tube 210 is not a direct heat source, the fluctuation of the water in the lumen of the protection tube 210 is relatively stable, thereby facilitating the measurement of the actual water level in the liner cavity 201 a. In addition, when boiling of water is severe, the protection pipe 210 can disperse a partial fluctuation of the water, thereby reducing impact force of the water on the first and second water level detectors 208 and 209, which is advantageous in maintaining reliability of the first and second water level detectors 208 and 209.

Furthermore, as shown in fig. 3, since the protection pipe 210 partitions a part of the space in the inner container chamber 201a, water vapor generated by evaporation of water between the inner container wall and the protection pipe 210 can be discharged to the outside as long as the space between the inner container wall and the protection pipe 210 is filled with the water vapor, thereby improving the steam generating speed of the steam generating device 200. In addition, as shown in fig. 3, a steam diversion hole 210a is formed on the wall of the protection tube 210, and the diversion hole 210a is relatively close to the top of the liner 201. The shunt holes 210a can uniformly disperse steam within the lumen of the liner chamber 201a and the protection tube 210, thereby facilitating the maintenance of stable air pressure between the liner wall and the protection tube 210.

In this embodiment, the protection tube 210 is further provided to increase the metal surface in the liner cavity 201a, so that the metal surface except the liner wall reacts with carbonate ions in water, thereby protecting the liner wall as a heating source, and slowing down the scale generation rate on the liner wall surface, so as to increase the service life of the liner.

Further, in this embodiment, a decontamination rod 216 is further disposed in the liner 201, and the first flange 202 of the decontamination rod 216 is relatively fixed, and illustratively, a part of the decontamination rod 216 is inserted into the drain hole 202a, and another part of the decontamination rod extends into the liner cavity 201a or the protection tube 210. Optionally, the decontamination bar 21 is a magnesium bar, and can react with carbonate ions in water, so as to slow down scale generated on the inner wall of the liner 201, thereby being beneficial to prolonging the service life of the steam generating device 200.

The above description of the preferred embodiments of the present utility model should not be taken as limiting the scope of the utility model, but rather should be understood to cover all modifications, variations and adaptations of the present utility model using its general principles and the following detailed description and the accompanying drawings, or the direct/indirect application of the present utility model to other relevant arts and technologies.
