[0022] Example 1

[0023] Please see Figure 1-5 The present invention provides the following technical solution: an electric heating steam generator with controllable water intake includes a shell 1, an induction component 2 is provided in the middle of the upper end of the shell 1, a support frame 8 is provided on one side of the shell 1, a water filter component 9 is provided at the upper end of the support frame 8, a water inlet pipe 7 is connected between the bottom of the water filter component 9 and the shell 1, a water level gauge 4 is provided on the other side of the shell 1, an air outlet pipe 3 is provided on the upper end of the shell 1 near the water level gauge 4, a control component 5 is provided on the side of the shell 1, an observation window 6 is provided in the middle of the surface of the shell 1, a heater 11 is provided on the inner bottom surface of the shell 1, and a float plate 10 is connected to the lower end of the induction component 2.

[0024] Specifically, the water filtration assembly 9 includes a water filtration tank 91, a water injection pipe 92, a filter box 93, and a liquid outlet 94. The upper end of the support frame 8 is provided with the water filtration tank 91, the upper end of the water filtration tank 91 is provided with the water injection pipe 92, the bottom of the water filtration tank 91 is provided with the liquid outlet 94, and several filter boxes 93 are inserted obliquely in the middle of the water filtration tank 91.

[0025] By adopting the above technical solution, water is added to the water filter tank 91 through the water injection pipe 92, filtered through the filter box 93, and the filtered water is discharged from the liquid outlet 94.

[0026] Specifically, the filter box 93 includes a filter cotton rack 931, a box body 933, and a handle 934. The filter cotton rack 931 is installed inside the box body 933, and the handle 934 is installed in the middle of the side of the box body 933.

[0027] By adopting the above technical solution, the box 933 can be pulled out of the water filter tank 91 by holding the handle 934, the impurities collected in the box 933 can be poured out, the filter cotton frame 931 can be lifted and removed, and a new filter cotton frame 931 can be replaced. The replacement is convenient and the filtration efficiency is guaranteed.

[0028] Specifically, a magnetic sheet 932 is provided on the bottom surface of the inner side of the box 933, and the filter cotton frame 931 is magnetically attracted and fixed to the magnetic sheet 932.

[0029] By adopting the above technical solution, the filter cotton frame 931 and the magnetic sheet 932 are magnetically fixed, preventing the filter cotton frame 931 from moving easily and ensuring stable filtration.

[0030] In this embodiment, water is added to the filter tank 91 through the water inlet pipe 92 and filtered through the filter cotton frame 931. The filtered water is discharged from the outlet 94 and transported into the outer shell 1 through the water inlet pipe 7. The heater 11 heats the water, and as the water is heated, water vapor is discharged from the steam outlet pipe 3. By holding the handle 934, the box 933 is pulled out of the filter tank 91, the impurities collected in the box 933 are poured out, the filter cotton frame 931 is lifted and removed, and a new filter cotton frame 931 is replaced. The filter cotton frame 931 is magnetically fixed to the magnetic piece 932, making replacement convenient and ensuring filtration efficiency.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the sensing component 2 includes a slide rail 21, a lead screw 22, a drive motor 23, a lifting rod 24, a pressure sensor 26, a guide rod 27, a top pad 28, and a limiting groove 29. The slide rail 21 is provided in the middle of the upper end of the outer shell 1. The drive motor 23 is provided on the top of the slide rail 21. The shaft of the drive motor 23 is connected to the lead screw 22. The lifting rod 24 is provided on the surface of the lead screw 22. The limiting grooves 29 are provided on both sides inside the lifting rod 24. The pressure sensor 26 is provided on the top of the limiting groove 29. The guide rod 27 is provided inside the limiting groove 29. The top pad 28 is provided at the bottom of the guide rod 27.

[0033] By adopting the above technical solution, the drive motor 23 rotates, driving the lead screw 22 to rotate. The lead screw 22 drives the lifting rod 24 to move, so that the float 10 moves to the corresponding position. The lifting structure has good sealing performance and is not easy to cause water vapor to leak out. The water level inside the outer shell 1 is divided, and water vapor is discharged from the vent pipe 3. At this time, the water level will gradually drop. When it drops to the bottom of the float 10, the float 10 is on the water surface, so the float 10 can no longer push the top pad 28, so the guide rod 27 can no longer push the pressure sensor 26. At this time, the background system will detect that the pressure sensor 26 is no longer under initial pressure, and thus shut down the heater 11. In this way, the amount of water used by the steam generator can be controlled.

[0034] Specifically, limit blocks 25 are provided on both sides of the lifting rod 24, and the limit blocks 25 are slidably connected to the inner wall of the slide rail 21.

[0035] By adopting the above technical solution, it is ensured that the lead screw 22 drives the lifting rod 24 to move within the slide rail 21.

[0036] In this embodiment, the drive motor 23 rotates, driving the lead screw 22 to rotate. The lead screw 22 drives the lifting rod 24 to move, causing the float 10 to move to the corresponding position. The lifting structure has good sealing performance, making it difficult for water vapor to leak out. The water level inside the outer shell 1 is divided, and water vapor is discharged from the vent pipe 3. At this time, the water level will gradually drop. When it drops to the bottom of the float 10, the float 10 is on the water surface, so the float 10 can no longer push the top pad 28, thus the guide rod 27 can no longer push the pressure sensor 26. At this time, the background system will detect that the pressure sensor 26 is no longer under initial pressure, thereby turning off the heater 11. In this way, the amount of water used by the steam generator can be controlled.

[0037] The structure and operating principle of the outer shell 1, pressure sensor 26, air outlet pipe 3, water level gauge 4, control component 5, float plate 10 and heater 11 in this utility model have been disclosed in an electric heating steam generator with convenient water volume control disclosed in Chinese patent application number 202420482882.9.

[0038] The working principle and usage process of this utility model are as follows: Water is added to the filter tank 91 through the water inlet pipe 92 and filtered through the filter cotton frame 931. The filtered water is discharged from the outlet 94 and transported into the outer shell 1 through the inlet pipe 7. The heater 11 heats the water, causing water vapor to be discharged from the vent pipe 3. The box 933 is pulled out of the filter tank 91 by holding the handle 934, the impurities collected in the box 933 are poured out, the filter cotton frame 931 is lifted and removed, and a new filter cotton frame 931 is replaced. The filter cotton frame 931 is magnetically fixed to the magnetic piece 932, making replacement convenient and ensuring filtration efficiency. The system is powered by an electric motor. The rotation of the machine 23 drives the lead screw 22 to rotate, and the lead screw 22 drives the lifting rod 24 to move, so that the float 10 moves to the corresponding position. The lifting structure has good sealing performance and is not easy to cause water vapor to leak out. The water level inside the outer shell 1 is divided, and water vapor is discharged from the vent pipe 3. At this time, the water level will gradually drop. When it drops to the bottom of the float 10, the float 10 is on the water surface, so the float 10 can no longer push the top pad 28, so the guide rod 27 can no longer push the pressure sensor 26. At this time, the background system will detect that the pressure sensor 26 is no longer under initial pressure, and thus shut down the heater 11. In this way, the amount of water used by the steam generator can be controlled.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
