[0002] Steam is widely used as an important energy carrier in many fields such as industrial production, medical and health care, and catering services. It is used in various processes such as heating, cooking, and sterilization. As one of the key equipment for generating steam, the performance of electric heating steam generators directly affects the production efficiency and operating costs of related industries.
[0003] In existing technologies, traditional electric steam generators operate under high temperature and pressure for extended periods. Various minerals in the water, such as calcium and magnesium ions, undergo chemical reactions under heat, forming hard scale. Scale buildup is extremely problematic in traditional steam generators. Long-term scale accumulation not only reduces heat transfer efficiency and exacerbates energy waste, but also corrodes internal metal components, shortening the equipment's lifespan and potentially causing safety accidents in extreme cases. Furthermore, existing electric steam generators on the market employ various assembly methods, some using welding and others threaded connections, making disassembly extremely difficult. This makes cleaning internal scale inconvenient for operators, resulting in a cumbersome and time-consuming process. Therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency electric heating steam generator, which has the advantage of making it easy to clean the scale inside the steam generator.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency electric heating steam generator, comprising:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 4 As shown, this utility model provides a high-efficiency electric heating steam generator, comprising:
[0025] Outer tub 1, with inner tub 2 fixedly fitted inside the outer tub 1;
[0026] A fixing mechanism is installed at the top of the outer barrel 1;
[0027] The fixing mechanism includes a top cover 3, the bottom of which is movably connected to the top of the outer tub 1, the bottom of which is fitted to the top of the inner tub 2, a hinge block 4 fixedly installed on the outer surface of the top cover 3, a rotating rod 5 hinged inside the hinge block 4, a pull block 6 movably connected inside the rotating rod 5, a moving rod 7 fixedly sleeved on the outer surface of the pull block 6, a lifting plate 8 fixedly installed at the bottom of the moving rod 7, a screw 9 threaded inside the lifting plate 8, the top of the screw 9 movably sleeved with the bottom of the outer tub 1, and a turning block 10 fixedly installed at the bottom of the screw 9.
[0028] Due to the design of the screwing block 10, the operator can rotate the screw 9 by turning the screwing block 10. Since the screw 9 is threadedly connected to the lifting plate 8, when the screw 9 rotates, it will drive the four moving rods 7 through the lifting plate 8. When the lifting plate 8 drives the four pulling blocks 6 to move upward through the four moving rods 7, the four pulling blocks 6 will release the pull and lock on the rotating rod 5 during the movement, so that the rotating rod 5 can rotate around the hinge block 4 as the axis. When the inside of the rotating rod 5 releases the contact with the pulling blocks 6 during rotation, the operator can remove the top cover 3 from the outer barrel 1 as a whole. At this time, the inside of the steam generator will be in the open state, which makes it easier for the operator to clean the scale.
[0029] Among them, a sealing ring 12 is fixedly installed at the bottom of the top cover 3, and the outer surface of the sealing ring 12 is movably connected to the inside of the inner tub 2. A washer 11 is movably connected at the bottom of the top cover 3, and the bottom of the washer 11 is fixedly connected to the top of the inner tub 2.
[0030] Due to the design of the sealing ring 12 and the gasket 11, the sealing between the top cover 3 and the outer barrel 1 and the inner barrel 2 will be enhanced.
[0031] The top cover 3 is fitted with a heating rod 13 inside the inner tub 2. The heating rod 13 is fitted with an air outlet pipe 14 inside the center of the top of the top cover 3. The top right side of the top of the top cover 3 is fitted with a water inlet pipe 15.
[0032] Due to the design of the heating rod 13, the water inside the inner tub 2 can be heated. The design of the vent pipe 14 allows steam to move to the outside of the inner tub 2 through the vent pipe 14. Due to the design of the water inlet pipe 15, the operator can add water to the inside of the inner tub 2 through the water inlet pipe 15.
[0033] The outer barrel 1 and the inner barrel 2 are filled with an insulation layer 16, which is made of foamed polyurethane material.
[0034] Due to the design of the insulation layer 16, it will be able to provide good insulation for the inner barrel 2.
[0035] Among them, the outer surface of the outer barrel 1 is fixedly sleeved with a support frame 17, and the inside of the top of the support frame 17 is movably sleeved with the outer surface of the moving rod 7.
[0036] Due to the design of the support frame 17, it will provide good support for the outer bucket 1 as a whole, so that the outer bucket 1 can be placed stably on the ground. Furthermore, since the inside of the top of the support frame 17 is movably connected to the outer surface of the moving rod 7, the moving rod 7 can only move up and down along the inside of the top of the support frame 17.
[0037] The inner barrel 2 has a fixed base 18 at the bottom, a vertical rod 19 at the top, a float 20 on the outer surface of the vertical rod 19, and a metal ring 21 at the bottom.
[0038] Because the float 20 has a hollow structure and is movably connected to the outer surface of the vertical rod 19, the height of the float 20 will change with the water level under the action of buoyancy. During this process, the float 20 will move up and down along the outer surface of the vertical rod 19, and at the same time, the metal ring 21 will move up and down under the action of the float 20.
[0039] The first wire 22 and the second wire 23 are fixedly sleeved inside the left and right sides of the fixing base 18, respectively. The outer surfaces of the first wire 22 and the second wire 23 are fixedly sleeved inside the inner barrel 2, the insulation layer 16 and the top cover 3, respectively. The bottom end of the second wire 23 is connected to a buzzer 24, and the top end of the buzzer 24 is fixedly connected to the bottom end of the outer barrel 1.
[0040] When the water level inside the inner tub 2 drops below the top of the fixed base 18, it indicates that the water level inside the inner tub 2 is critically low. At this time, the water will no longer be able to support the float 20, so the float 20 will be located at the bottom of the outer surface of the vertical rod 19. At the same time, the metal ring 21 will come into contact with the first wire 22 and the second wire 23. Then, the first wire 22 will conduct electricity to the buzzer 24 through the metal ring 21 and the second wire 23, causing the buzzer 24 to sound an alarm to remind the operator to add water to the inner tub 2.
[0041] Working principle and usage process of this utility model:
[0042] Because the float 20 is hollow, its density is lower than that of water. Therefore, when the inner tub 2 is full of water, the float 20 will be located at the top of the outer surface of the vertical rod 19 under the action of buoyancy. When the steam generator is running, the water inside the inner tub 2 will continuously decrease under the action of high temperature. As the water level inside the inner tub 2 drops, the float 20 will move downwards along the outer surface of the vertical rod 19. During this process, the metal ring 21 will move downwards under the action of the float 20. When the water level inside the inner tub 2 is below the top of the fixed base 18, the water level inside the inner tub 2 will then be lower. When the water level in the inner tank is too low, due to the lack of water support, the float 20 will be located at the bottom of the outer surface of the vertical rod 19. At the same time, the bottom of the metal ring 21 will simultaneously contact the first wire 22 and the second wire 23. At this time, the current inside the first wire 22 will be transmitted to the first wire 22 through the metal ring 21. Then, the first wire 22 will guide the current to the buzzer 24. The buzzer 24 will then emit a sharp and continuous alarm sound to remind the operator to add water to the inner tank 2 in time, thereby realizing the function of automatic water level monitoring.
[0043] When the operator needs to clean the scale inside the inner tank 2, the operator first turns the turning block 10. The screw 9 will then rotate under the influence of the turning block 10. Since the outer surface of the screw 9 is threaded into the inner thread of the lifting plate 8, the rotation of the screw 9 will drive the lifting plate 8 to move. Simultaneously, the lifting plate 8 will drive the four moving rods 7 to move along the inside of the top of the support frame 17. Due to the limiting mechanism inside the top of the support frame 17, the moving rods 7 can only move up and down. Therefore, the four moving rods 7 will move upwards along the inside of the top of the support frame 17 under the influence of the lifting plate 8. During the movement, the four moving rods 7 will drive the four pulling blocks 6 to move upward along the inside of the four rotating rods 5. During this process, the four pulling blocks 6 will release the pulling and locking action of the rotating rods 5, so that the rotating rods 5 can rotate around the hinge point with the hinge block 4 as the axis. When the four rotating rods 5 release the contact with the pulling blocks 6 during rotation, the operator can remove the top cover 3 from the top of the outer barrel 1 and the inner barrel 2. At this time, the operator can clean the scale inside the inner barrel 2 and the outer surface of the heating rod 13, thus realizing the function of facilitating the cleaning of scale inside the steam generator.
