It is convenient to use and can be removed when not in use without affecting the normal operation of the boiler body. However, it still has some shortcomings in use.

[0004] While the aforementioned device can clean the dirt remaining on the side walls during use, the scraped-off scale falls into the bottom of the electric boiler body, making subsequent cleaning difficult and increasing manual labor. Furthermore, it cannot recover and utilize heat, increasing the device's energy consumption and thus raising costs, indicating certain shortcomings in its use. Utility Model Content

At the same time, it cannot recover and utilize heat, which increases the energy consumption of the device and thus increases the cost, and has certain defects in use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving and efficient electric boiler, comprising a boiler body, wherein a liquid tank and a heating chamber are provided inside the boiler body, and a heating device is embedded in the lower end of the boiler body, a water pump is fixedly connected to the top of the boiler body, and a box is fixedly connected to the water outlet at the bottom of the boiler body. Also includes: A heat storage chamber is provided at the top of the boiler body. A heating tube is fixedly connected inside the heat storage chamber, and the heat storage chamber is connected to the heating chamber through a gas supply pipe. A fixed frame is installed in the middle of the liquid tank, and a collection box is rotatably mounted on the fixed frame. The collection box is connected to a baffle by a rope. An impeller is rotatably connected inside the boiler body. A reciprocating screw is fixedly connected to the bottom end of the impeller. A moving plate is threaded onto the reciprocating screw, and a scraper is fixedly connected to the bottom end of the reciprocating screw. The chamber is rotatably connected to a filter plate, and a guide plate is axially connected to the lower inner side of the chamber. The side walls of the chamber are symmetrically provided with discharge holes.

[0007] Preferably, the heating tube has a spiral structure, the water outlet end of the heating tube is aligned with the impeller, and the heating tube is made of copper.

[0008] Preferably, the baffle is slidably disposed in the slot inside the boiler body, and the baffle is connected to the inner wall of the slot inside the boiler body by a compression spring to form an elastic telescopic structure. Furthermore, two sets of baffles are symmetrically arranged on the left and right sides of the gas transmission pipe, and the baffles are sealed and fitted to the water outlet end of the gas transmission pipe.

[0009] Preferably, two sets of collection boxes are symmetrically arranged about the liquid tank, and a torsion spring that provides a restoring elastic force is connected between the collection box and the fixing frame, and the liquid tank and the heat storage chamber are in communication with each other.

[0010] Preferably, the movable plate is circular, and an annular brush head is fixedly connected to the outer side of the movable plate, and the brush head is in contact with the inner wall of the heating chamber for removing scale.

[0011] Preferably, the filter plate has a semi-circular structure, and two sets of filter plates are symmetrically arranged about the left and right sides of the housing. The filter plate shaft ends are connected to the housing through torsion springs, and the filter plate is in contact with the scraper.

[0012] Preferably, two sets of guide plates are symmetrically arranged about the left and right sides of the box, and one end of the guide plate is connected to the filter plate by a pull rope, and the positions of the guide plates and the discharge holes correspond to each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this energy-saving and efficient electric boiler can effectively recover and utilize the heat from the high-temperature steam generated after water boils, preheat the cold water in the heating tube, reduce heating time, reduce energy consumption, and improve the efficiency of the boiler. At the same time, it can clean the inner wall of the heating chamber to avoid the formation of scale. It is highly practical. The specific details are as follows: 1. The device is equipped with a heating pipe and a gas supply pipe. The high-temperature steam generated after the heating chamber is boiled is transported to the heat storage chamber through the gas supply pipe. The cold water in the heating pipe exchanges heat with the steam in the heat storage chamber, thereby heating the cold water in the heating pipe. The spiral heating pipe can make the cold water in it evenly heated, reduce the time required for subsequent heating, thereby reducing energy consumption and improving the practicality of the device.

[0014] 2. Equipped with a baffle and a collection box, the liquefied water vapor flows into the collection box through the opening. When the water volume inside the collection box reaches a critical value, it will rotate automatically, and then pull the baffle synchronously by pulling the rope to open the water inlet of the heating tube, thereby realizing intermittent water addition, preventing the water in the boiler from burning dry and improving the service life of the device.

[0015] 3. Equipped with an impeller, reciprocating screw, and moving plate, the impeller rotates due to water impact, which in turn drives the reciprocating screw to rotate, causing the moving plate to rotate in contact with the inner wall of the heating chamber, thereby cleaning the inner wall of the heating chamber, preventing scale formation, and improving the heating efficiency of the boiler.

[0016] 4. Equipped with scrapers and filter plates, the filter plates achieve solid-liquid separation and isolate the scraped-off scale, thereby improving water quality. Furthermore, the rotating impeller causes the scrapers to rotate and adhere to the surface of the filter plates, thus cleaning the filter plates and effectively preventing the filter holes on the filter plates from becoming clogged, thereby improving the filtration effect.

[0017] 5. Equipped with a guide plate, pushing the guide plate to rotate will cause the pull rope to pull the filter plate to rotate, cleaning the scale filtered out of the filter plate and making it easy for the scale to be discharged from the discharge hole along the guide plate, thus improving the practicality of the device.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figures 1-6 As shown, this utility model provides a technical solution: an energy-saving and efficient electric boiler, including a boiler body 1, a liquid tank 6 and a heating chamber 10 are provided inside the boiler body 1, and a heating device 2 is embedded in the lower end of the boiler body 1. A water pump 3 is fixedly connected to the top of the boiler body 1, and a box 18 is fixedly connected to the water outlet at the bottom of the boiler body 1.

[0022] This technical solution includes a heating device 2 and a heating chamber 10. The water pump 3 works to transport cold water from the liquid tank 6 to the heating chamber 10 through a pipeline, thereby turning on the heating device 2. This allows the current to pass through the resistance wire or electrodes to generate resistance heat, which can effectively convert electrical energy into heat energy. At the same time, the generated heat energy will be transferred to the water through conduction and convection, causing the water temperature to gradually rise until it reaches the set temperature.

[0023] Example 2: Based on Example 1, as follows Figures 1-6As shown, a heat storage chamber 19 is provided at the top of the boiler body 1. A heating tube 4 is fixedly connected inside the heat storage chamber 19, and the heat storage chamber 19 is connected to the heating chamber 10 through a gas supply pipe 5. A fixed frame is provided in the middle of the liquid tank 6, and a collection box 9 is rotatably mounted on the fixed frame. The collection box 9 is connected to a baffle 7 by a rope. The heating tube 4 has a spiral structure, and the water outlet end of the heating tube 4 is aligned with the impeller 11. The heating tube 4 is made of copper. The baffle 7 is slidably installed in the slot inside the boiler body 1, and the baffle 7 is connected to the inner wall of the slot inside the boiler body 1 by a compression spring 8 to form an elastic telescopic structure. Two sets of baffles 7 are symmetrically arranged on the left and right sides of the gas supply pipe 5. The baffles 7 are sealed and fitted to the water outlet end of the gas supply pipe 5. Two sets of collection boxes 9 are symmetrically arranged on the liquid tank 6, and a torsion spring that provides a restoring elastic force is connected between the collection box 9 and the fixed frame. The liquid tank 6 and the heat storage chamber 19 are interconnected.

[0024] In this technical solution, as follows Figure 2 As shown, by using the heating pipe 4 and the gas supply pipe 5, the high-temperature steam generated after the water in the heating chamber 10 is boiled can be transported to the heat storage chamber 19 through the gas supply pipe 5 for recycling and heat exchange with the cold water in the heating pipe 4, thereby initially heating the water, reducing the time required for subsequent grilling, thus reducing energy consumption and improving boiler efficiency. At the same time, by pulling the baffle 7 through the collection box 9, water is intermittently added to the boiler to prevent it from burning dry and to extend the service life of the device.

[0025] Its adoption is as follows Figure 1 and Figures 3-6 The technical solution shown first involves rotating the collection box 9 to slide the baffle 7 open. This allows the water pump 3 to pump a certain amount of cold water from the liquid tank 6 through the heating pipe 4 into the heating chamber 10. Then, the collection box 9 is released, and the torsion spring resets the collection box 9. The baffle 7 seals the water inlet at the bottom of the heating pipe 4. When the water in the heating chamber 10 boils, a large amount of high-heat water vapor is generated and enters the heat storage chamber 19 through the gas pipe 5. The water vapor then comes into contact with the surface of the heating pipe 4, converting heat and raising the temperature of the cold water in the heating pipe 4. The water in the heat storage chamber 19 liquefies upon cooling and flows through the opening into the collection box 9 in the liquid tank 6. When the water volume in the collection box 9 reaches a critical value, it rotates automatically. This causes the baffle 7 to slide while the compression spring 8 contracts, allowing the water in the heating pipe 4 to flow into the heating chamber 10 for heating, thus achieving intermittent automatic water replenishment.

[0026] Example 3: Based on Examples 1 and 2, as follows... Figure 1 and Figure 2As shown, an impeller 11 is rotatably connected inside the boiler body 1. A reciprocating screw 12 is fixedly connected to the bottom end of the impeller 11. A moving plate 13 is threaded onto the reciprocating screw 12, and a scraper 14 is fixedly connected to the bottom end of the reciprocating screw 12. A filter plate 15 is rotatably connected inside the housing 18, and a guide plate 16 is axially connected to the inner side of the lower end of the housing 18. Discharge holes 17 are symmetrically opened on the side wall of the housing 18. The moving plate 13 is circular, and an annular brush head is fixedly connected to the outer side of the moving plate 13. The brush head is attached to the inner wall of the heating chamber 10 for descaling. The filter plate 15 has a semi-circular structure and two sets of filter plates 15 are symmetrically arranged about the left and right sides of the housing 18. The shaft end of the filter plate 15 is connected to the housing 18 through a torsion spring. The filter plate 15 is attached to the scraper 14. Two sets of guide plates 16 are symmetrically arranged about the left and right sides of the housing 18. One end of the guide plate 16 is connected to the filter plate 15 through a pull rope. The guide plate 16 is positioned corresponding to the discharge hole 17.

[0027] In this technical solution, as follows Figure 2 As shown, by utilizing the reciprocating screw 12 and the moving plate 13, when the impeller 11 rotates, the reciprocating screw 12 drives the moving plate 13 to move up and down, thereby brushing the inner wall of the boiler through the brush head, avoiding the formation of scale, improving the heating efficiency of the device. At the same time, solid-liquid separation can be achieved through the filter plate 15, separating the scale. The scraper 14 rotates against the surface of the filter plate 15, automatically cleaning the filter plate 15, preventing scale from clogging the filter screen and improving the filtration effect.

[0028] Its adoption is as follows Figure 1 and Figures 3-6 The technical solution shown firstly involves the impeller 11 rotating due to water flow impact, which in turn drives the reciprocating screw 12 to rotate. This causes the moving plate 13 to move up and down along the guide rod, scrubbing the inner wall of the boiler body 1 and scraping off the attached scale, thus improving the heating effect of the device. Simultaneously, solid-liquid separation is achieved through the filter plate 15, filtering out the scale. As the reciprocating screw 12 rotates, it drives the scraper 14 to scrape against the surface of the filter plate 15, thereby automatically cleaning the filter plate 15 and improving the filtration effect. When it is necessary to clean the filtered scale, simply push the guide plate 16 to rotate with a tool. During its rotation, the filter plate 15 is pulled synchronously by the pull rope, causing the discharge hole 17 to open. At this time, the scale on the surface of the filter plate 15 will slide down the guide plate 16 under gravity and be discharged through the discharge hole 17, thus completing a series of operations.
