Referring to fig. 1 and 2, a steam generator 100 provided in the present application will now be described. The steam generator 100 includes a cabinet 11, a heater 12, a partition 13 and a baffle 14, an inlet pipe 111 and an outlet pipe 112 are respectively installed at both ends of the cabinet 11, and the heater 12 is installed on the cabinet 11, so that water enters the cabinet 11 from the inlet pipe 111 to be heated to form steam, and then is discharged from the outlet pipe 112. Since the steam generated by heating the water has a large number of water droplets, when the water is directly discharged from the outlet pipe 112 after being heated in the cabinet 11, the steam has a large number of water droplets, i.e., the steam has a large water content, which means the water droplet content in the steam. The partition plate 13 is installed in the cabinet 11, the inlet pipe 111 and the outlet pipe 112 are respectively located at two sides of the partition plate 13, and the partition plate 13 is provided with a first through hole 131 and a plurality of first filtering holes 132, so that water is heated in the cabinet 11, and after steam is obtained, the steam is discharged from the outlet pipe 112 through the partition plate 13. The baffle 14 is used for opening and closing the first filtering hole 132, that is, the baffle 14 can close the first filtering hole 132 and can also open the first filtering hole 132, and the baffle 14 is provided with a second through hole 141 corresponding to the first through hole 131, so that when the baffle 14 closes the first filtering hole 132, the steam generated in the cabinet 11 can pass through the first through hole 131 and the second through hole 141 and then be discharged from the outlet pipe 112. When the baffle plate 14 opens the first filtering holes 132, the steam is filtered by the first filtering holes 132 to block and filter water drops in the steam, so as to reduce the water drop content in the steam. The steam generator 100 can operate in two modes, a direct injection mode and a filtration mode:

direct injection mode: referring to fig. 3, the baffle 14 closes the first filtering hole 132, and the steam generated in the cabinet 11 passes through the first through hole 131 and the second through hole 141 and is then discharged from the outlet pipe 112; because of the high water content of the steam, which has a high weight, it is ejected directly when exiting the outlet pipe 112. When the temperature is low, the generated steam is reduced, and the outlet pipe 112 sprays water containing steam. When the temperature is again lowered and further the water in the cabinet 11 does not generate steam, hot water is sprayed. Of course, when the temperature is higher, more steam is generated in the cabinet 11, and the water content in the steam is correspondingly reduced. Therefore, when the baffle 14 closes the first filtering holes 132, the temperature is gradually increased from low to high, and the liquid sprayed from the outlet pipe 112 is gradually changed from water, water flow containing steam, steam containing more water to steam containing less water, so as to adapt to different working condition requirements.

And (3) a filtering mode: referring to fig. 4, the baffle plate 14 opens the first filtering hole 132, and the steam generated in the cabinet 11 is filtered through the first filtering hole 132 to block and filter water droplets in the steam, so as to reduce the water droplet content in the steam, and then is discharged through the outlet pipe 112. And when the heating temperature is increased, the amount of the steam can be further increased, and the content of water drops in the steam can be reduced to adapt to different working condition requirements. Compared with the method of directly heating the steam, the scheme is more energy-saving under the condition of the same water content after the steam is filtered through the first filtering holes 132 on the partition plate 13.

Therefore, the steam generator 100 can meet various different working condition requirements, and has the advantages of simple structure, convenient control, high reliability and low cost.
