The steam extraction assembly 16 includes a hollow column 17, a speed-limiting electromagnetic strip 18, and a sliding... Magnetic ring 19, push-pull spring 20, limiting plate 21, driving electromagnet 22, and synchronization magnetic block 31; the hollow column 17 is connected and disposed on the side of the lower water tank 13 away from the steaming column 12; multiple sets of speed-limiting electromagnetic strips 18 are disposed on the outside of the hollow column 17; the sliding magnetic ring 19 is slidably disposed on the outside of the hollow column 17 and the speed-limiting electromagnetic strips 18; the push-pull spring 20 is disposed between the sliding magnetic ring 19 on the outside of the hollow column 17 and the speed-limiting electromagnetic strips 18 and the lower water tank 13.

The water filter assembly 23 includes a water-absorbing cotton layer 24, a steam inlet 25, and a float-type drain valve 26.

[0021] The water tank 4 is equipped with a controller 30 on its side wall.

[0022] The controller 30 is electrically connected to the heating plate 6, the speed limiting electromagnetic strip 18, and the driving electromagnet 22, respectively.

[0023] In practical use, the entire steam generating device is used in conjunction with the outer shell of the electric steam box, with the outer shell of the electric steam box fitted over the outside of the steam generating device; The controller 30 controls the start of the drive electromagnet 22. The drive electromagnet 22 is energized and generates magnetism. The drive electromagnet 22 and the sliding magnetic ring 19 are set with the same pole. The drive electromagnet 22 is fixed to the side wall of the limit plate 21 and uses the deformation characteristics of the push spring 20 to push the sliding magnetic ring 19. The sliding magnetic ring 19 slides along the hollow column 17 and the speed limiting electromagnetic strip 18 towards the end closer to the drain cylinder 13. When the sliding magnetic ring 19 slides, it drives the synchronous magnetic block 31 to slide along the inner wall of the hollow column 17 and approach the drain cylinder 13 through magnetic attraction. A magnetic shielding layer is set between the speed limiting electromagnetic strip 18 and the hollow column 17 in advance to avoid the speed limiting electromagnetic strip 18 interfering with the movement of the synchronous magnetic block 31. The operator injects water into the water tank 4 through the water supplement valve 5, places the food to be heated and steamed on the upper wall of the food supporting net plate 15, and controls the controller 30 to start the heating disc 6. The heating disc 6 heats the water in the water tank 4, and the heated water turns into steam and flows into the steam tank 8. The steam tank 8 discharges the steam into the electric steamer through the steam outlet 9. A large amount of water vapor naturally rises in the closed cavity and fills the entire space, thereby heating the food. The steam condenses into water on the cold upper cavity wall surface and easily drips onto the food, affecting the taste. When the food is heated and steamed, the controller 30 controls the drive electromagnet 22 to be powered off and demagnetized. The controller 30 controls the speed limiting electromagnet strip 18 to be started and controls the current value flowing into it. The speed limiting electromagnet strip 18 generates magnetism after being powered on. The speed limiting electromagnet strip 18 and the sliding magnetic ring 19 are arranged with opposite poles. By adjusting the current value flowing into the speed limiting electromagnet strip 18, the magnetic field strength between the speed limiting electromagnet strip 18 and the sliding magnetic ring 19 is controlled, the rebound reset time of the push-pull spring 20 is slowed down, the sliding magnetic ring 19 slowly resets to the initial position, and the sliding magnetic ring 19 resets to the initial position. The time is consistent with the heating and steaming time of the food. The sliding magnetic ring 19 slowly resets under the magnetic attraction of the speed limiting electromagnet strip 18. The sliding magnetic ring 19 drives the synchronous magnetic block 31 to slide along the inner wall of the hollow column 17 to extract the air in the lower water cylinder 13. The lower water cylinder 13 draws the steam rising to the top of the electric steamer into the inside of the temperature guide copper pipe 14 through the floating ball type drain valve 26. The water in the steam is absorbed by the water absorbing cotton layer 24, and part of the water droplets condensed on the top of the electric steamer drop into the inside of the water absorbing cotton layer 24 through the steam inlet 25. The water in the inside of the water absorbing cotton layer 24 flows downward along the temperature guide copper pipe 14 and enters the inside of the lower water cylinder 13. The lower water cylinder 13 discharges the condensed water into the inside of the hollow column 17, thereby reducing the probability of the condensed water droplets falling on the food. When the sliding magnetic ring 19 drives the synchronous magnetic block 31 to slide to the position between the floating ball type drain valve 26 and the limiting plate 21, the condensed water in the inside of the hollow column 17 is discharged through the floating ball type drain valve 26. When the push-pull spring 20 is fully stretched to reset the sliding magnetic ring 19, the heating and steaming time of the surface food is up. At this time, the sliding magnetic ring 19 drives the synchronous magnetic block 31 to the position where the hollow column 17 is provided with the steam vent groove 32. The heating steam in the electric steamer is discharged from the heat dissipation valve 29 under the guidance of the steam inlet 25, the temperature guide copper pipe 14, the lower water cylinder 13, the hollow column 17, and the steam vent groove 32, thereby releasing the steam with a higher temperature in the electric steamer, preventing the operator from being scalded by the high-temperature steam when taking out the food. The above operation can be repeated next time.

[0024] It is to be understood that the terminology "including", "comprising", or any other variation thereof, is intended to cover a non-exclusive inclusion such that process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0025] The above describes the technical scheme and its implementation, which is not limited, and the drawings only show one of the embodiments of the technical scheme, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the technical scheme, without creative design, similar structure and embodiments of the technical scheme can be obtained, which should belong to the protection scope of the technical scheme.
