[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-5 As shown, an electric heating steam generator includes a water distribution pipe 11 and a steam cylinder 3. Multiple parallel water guide pipes 10 are arranged between the water distribution pipe 11 and the steam cylinder 3. A sealing cylinder 6 is located in the middle of each water guide pipe 10. Heating components 25, wound around the outside of the water guide pipes 10, are installed inside the sealing cylinder 6. A steam pipe 2 is installed on the steam cylinder 3, and two return pipes 12 are arranged between the steam cylinder 3 and the water distribution pipe 11. The two return pipes 12 are located on both sides of the water distribution pipe 11, and each return pipe 12 has a movable switch. A water outlet pipe 21 is installed inside the water distribution pipe 11, communicating with the return pipes 12. One end of the water outlet pipe 21 is equipped with a flange 23 fixedly connected to the water distribution pipe 11, and the other end of the water distribution pipe 11 is equipped with a water inlet pipe 8. A switch valve 7 is installed on the water inlet pipe 8. A water storage chamber 20 is formed between the water distribution pipe 11 and the water outlet pipe 21. A steam-water separator 1 is installed inside the steam cylinder 3.

[0022] A baffle 32 is installed inside the steam cylinder 3, dividing the inner cavity of the steam cylinder 3 into a first cavity 18 and a second cavity 15. The first cavity 18 is connected to the water distribution pipe 11 and the return pipe 12, and the second cavity 15 is connected to the steam pipe 2. The steam-water separator 1 includes a vent pipe 16, a motor 14, a drive gear 27, and a driven gear 28. Multiple vent pipes 16 are arranged in a circumferential array. The drive gear 27 is located at the center of multiple vent pipes 16. The two ends of the vent pipes 16 rotate with the steam cylinder 3 and the baffle 32, respectively. Multiple steam inlets 17 are provided on the vent pipes 16, and one end of the vent pipe 16 passes through the baffle 32 and is connected to the second cavity 15. The output of the motor 14... The shaft is fixedly connected to the driving gear 27, and the driven gear 28 is fixed on the air guide pipe 16 and meshes with the driving gear 27 for transmission. The motor 14 drives the driving gear 27 to rotate, which causes the driven gear 28 to drive the air guide pipe 16 to rotate. The water vapor in the steam cylinder 3 can enter the air guide pipe 16 from the steam inlet 17 and enter the second cavity 15 along the air guide pipe 16. During this process, the water vapor enters from different steam inlets 17 and impacts the water vapor flowing in the air guide pipe 16. This can accelerate the condensation of the water vapor. The water droplets formed will drip from the steam inlet 17 into the steam cylinder 3 when the air guide pipe 16 rotates, thus reducing the moisture in the water vapor.

[0023] Multiple annular baffles 29 are provided inside the steam duct 16. The annular baffles 29 are located between two adjacent steam inlets 17. While ensuring the flow of water vapor, the annular baffles 29 can increase the residence time of water vapor, thereby increasing the condensation time of water vapor and further reducing the moisture content in the water vapor.

[0024] The switching valve 7 includes a float 26 and a protrusion 13 on the outlet pipe 21. The protrusion 13 has an installation groove 19, and the float 26 is located in the installation groove 19. The diameter of the float 26 is larger than the inner diameter of the return pipe 12. When too much water is added to the water pipe 10, it will enter the steam cylinder 3 and then flow back to the protrusion 13 through the return pipe 12. When the buoyancy of the water on the float 26 is greater than its weight, the return pipe 12 is opened, allowing water to enter the outlet pipe 21 along the return pipe 12. When there is less water in the steam cylinder 3, the float 26 will block the return pipe 12, thereby preventing water vapor from entering the outlet pipe 21.

[0025] The sealing cylinder 6 includes two semi-cylindrical assemblies. The wiring terminal of the heating component 25 passes through one of the assemblies. Two fixing plates 30 are provided on the water pipe 10. The fixing plates 30 are fixedly connected to the assemblies by bolts. The two assemblies are connected to the fixing plates 30 by bolts to form a cylindrical structure, which can reduce the heat dissipation of the heating component 25 to the outside, thereby sealing the heat inside the sealing cylinder 6, thus reducing the power consumption of the heating component 25.

[0026] The water pipe 10 has multiple heat-conducting ring protrusions 31 with equal heights at the position between the sealing cylinders 6. The heating component 25 is located outside the heat-conducting ring protrusions 31. The heat-conducting ring protrusions 31 increase the heating area of ​​the water pipe 10, which can accelerate the heating of the water inside and the generation of water vapor.

[0027] The water distribution pipe 11 and the water outlet pipe 21 are respectively provided with a first installation pipe 24 and a second installation pipe 22. The lower end of the return pipe 12 is a stepped pipe structure that cooperates with the first installation pipe 24 and the second installation pipe 22. This design can facilitate the installation of the return pipe 12 and the connection between the return pipe 12 and the water outlet pipe 21.

[0028] A drain pipe 9 is also provided on the water distribution pipe 11. After the equipment finishes working, the excess water can be drained through the drain pipe 9 to prevent the water distribution pipe 11 and the water guide pipe 10 from rusting. A connecting pipe 4 is connected between the steam cylinder 3 and the water inlet pipe 8. A water level cylinder 5 is provided on the connecting pipe 4. The water level cylinder 5 can display the water level in the water guide pipe 10, so that the user can easily control the water inlet.

[0029] Working principle: When steam needs to be produced, water is introduced from the inlet pipe 8 into the distribution pipe 11, and then dispersed into the guide pipe 10. When the heating component 25 is working, it can heat the water in the guide pipe 10 and generate steam. The steam enters the steam cylinder 3, and then the steam enters the air guide pipe 16 from the steam inlet 17. The air guide pipe 16 rotates under the drive of the motor 14 and the drive gear 27, so that the steam is impacted by the steam entering the steam inlet 17 while it is flowing. This allows the steam molecules to condense into water droplets, thereby reducing the moisture content of the steam. After entering the second chamber 15, the steam is discharged through the steam pipe 2.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
