Description

Technical Field

[0001] This application relates to the field of electric boiler technology, and in particular to an automatic water inlet structure for an electric boiler. Background Technology

[0002] As a common heating device, the automatic water intake function of electric boilers is crucial to ensuring the normal operation of the equipment. The automatic water intake structure of traditional electric boilers mainly adopts a single water intake pipe, and achieves automatic control through the cooperation of solenoid valves and water level sensors.

[0003] In existing technologies, automatic water inlet structures are difficult to adapt to different working environments and water quality conditions during use, and cannot effectively solve the problems of scale accumulation and blockage, thus affecting the service life and working efficiency of electric boilers. Therefore, we propose an automatic water inlet structure for electric boilers to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing automatic water inlet structures, which are difficult to adapt to different working environments and water quality conditions during use, and cannot effectively solve the problems of scale accumulation and blockage, thereby affecting the service life and working efficiency of electric boilers. Therefore, this invention proposes an automatic water inlet structure for electric boilers.

[0005] The automatic water inlet structure for an electric boiler provided in this application adopts the following technical solution:

[0006] An automatic water inlet structure for an electric boiler includes a boiler body, a water inlet, and a water outlet. The water outlet is fixedly connected to the bottom of the boiler body. A filter chamber is provided inside the boiler body, and the water inlet is fixedly connected to the filter chamber.

[0007] The level gauge is fixedly installed inside the boiler body, and a control valve is installed on the water inlet. The level gauge is connected to the control valve.

[0008] The filtration mechanism is installed inside the filtration chamber and is used to intercept and filter impurities in the water.

[0009] The first through slot is located on the boiler body, and the second through slot is located on the boiler body.

[0010] Furthermore, a sealing groove is provided on one side of the inner wall of the filter chamber, and a sealing plate is slidably installed in the sealing groove. A sealing gasket and a connecting rod are fixedly connected to one side of the sealing plate. One end of the connecting rod is fixedly connected to one side of the push plate. When the push plate moves horizontally, the connecting rod drives the sealing plate to move horizontally.

[0011] Furthermore, the screw is threadedly connected to the push plate, and a first bevel gear is fixedly installed on the outside of the screw. A second bevel gear meshes with the first bevel gear. When the screw rotates, the first bevel gear drives the second bevel gear to rotate.

[0012] Furthermore, a first scraper is fixedly installed at the other end of the transmission rod, and a second scraper is fixedly installed at both ends of the first scraper. The first scraper and the two second scrapers are in contact with the inner wall of the boiler body. When the transmission rod rotates, the first scraper drives the two second scrapers to rotate.

[0013] Furthermore, a second through hole is provided on the bottom inner wall of the second through groove, and a transmission rod is rotatably installed in the second through hole. One end of the transmission rod is fixedly connected to the second bevel gear.

[0014] Furthermore, a motor is fixedly installed on one side of the inner wall of the first channel, and a first through hole is opened on the other side of the inner wall of the first channel. The first through hole communicates with the second channel and the filter chamber, and a screw is rotatably installed in the first through hole.

[0015] Furthermore, the filtration mechanism includes a filter screen, a water outlet hole is provided on the bottom inner wall of the filtration chamber, the filter screen is fixedly installed in the water outlet hole, and a push plate is slidably installed in the filtration chamber.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. This solution can monitor the water level inside the boiler body in real time through a level gauge. When the water level inside the boiler body drops to a preset threshold, the control valve will automatically open to allow water to enter. During the water intake process, the filter screen can intercept and collect impurities in the water to prevent excessive impurities from causing scale buildup inside the boiler body.

[0018] 2. This solution involves turning on the motor, which drives the screw to rotate. The screw then moves the push plate horizontally, pushing out impurities intercepted by the filter screen to prevent accumulation and blockage. Simultaneously, the screw drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear then drives the transmission rod to rotate, which in turn drives the first scraper to rotate. The first scraper then drives two second scrapers to rotate, thus enabling the first and two second scrapers to self-clean the inner wall of the boiler body, ensuring the service life of the electric boiler.

[0019] This invention facilitates the interception and treatment of impurities in water during use, thereby effectively solving the problems of scale accumulation and clogging, ensuring the service life and working efficiency of the electric boiler. It has a simple structure and is easy to use. Attached Figure Description

The water outlet 3 is fixedly connected to the bottom of the boiler body 1. A filter chamber 8 is provided inside the boiler body 1, and the water inlet 2 is fixedly connected to the filter chamber 8.

[0027] The level gauge 5 is fixedly installed inside the boiler body 1. A control valve 4 is installed on the water inlet 2. The level gauge 5 is connected to the control valve 4. The signal of the level gauge 5 is transmitted to the PLC controller. The PLC controller controls the opening and closing of the control valve 4 according to the preset water level value.

[0028] The filter mechanism is installed inside the filter chamber 8 and is used to intercept and filter impurities in the water.

[0029] The first through slot 6 is provided on the boiler body 1, and the boiler body 1 is provided with a second through slot 7.

[0030] In this embodiment, a sealing groove 14 is formed on one inner wall of the filter chamber 8. A sealing plate 15 is slidably installed in the sealing groove 14. A sealing gasket 16 and a connecting rod 12 are fixedly connected to one side of the sealing plate 15. One end of the connecting rod 12 is fixedly connected to one side of the push plate 11. When the push plate 11 moves horizontally, the connecting rod 12 drives the sealing plate 15 to move horizontally. A first scraper 20 is fixedly installed at the other end of the transmission rod 19. A second scraper 21 is fixedly installed at both ends of the first scraper 20. The first scraper 20 and the two second scrapers 21 are all... Contacting the inner wall of the boiler body 1, the first scraper 20 and the second scraper 21 are made of high-temperature and corrosion-resistant polytetrafluoroethylene (PTFE) or ceramic composite material, with flexible scraper blades embedded on their edges to ensure contact with the inner wall. When the transmission rod 19 rotates, the first scraper 20 drives the two second scrapers 21 to rotate. A motor 9 is fixedly installed on one side of the inner wall of the first through groove 6, and a first through hole is opened on the other side of the inner wall of the first through groove 6. The first through hole communicates with the second through groove 7 and the filter chamber 8. A screw 10 is rotatably installed in the first through hole.

[0031] In this embodiment, the screw 10 is threadedly connected to the push plate 11. A first bevel gear 17 is fixedly installed on the outer side of the screw 10, and a second bevel gear 18 meshes with the first bevel gear 17. When the screw 10 rotates, the first bevel gear 17 drives the second bevel gear 18 to rotate. A second through hole is opened on the bottom inner wall of the second through groove 7. A transmission rod 19 is rotatably installed in the second through hole. One end of the transmission rod 19 is fixedly connected to the second bevel gear 18.

The filter screen 13 is fixedly installed in the water outlet hole. A push plate 11 is slidably installed in the filter chamber 8.

[0032] The implementation principle of the automatic water inlet structure of an electric boiler in this application embodiment is as follows: During use, the water level in the boiler body 1 can be monitored in real time by the level gauge 5. When the water level in the boiler body 1 drops to a preset threshold, the control valve 4 automatically opens to allow water to enter. During the water inlet process, the filter screen 13 can intercept and collect impurities in the water, avoiding excessive impurities in the water from causing scale buildup inside the boiler body 1. At the same time, the motor 9 can be turned on, and the motor 9 drives the screw 10 to rotate. The screw 10 drives the push plate 11 to move horizontally. The push plate 11 can push out the impurities intercepted by the filter screen 13 to avoid accumulation and blockage. At the same time, the screw 10 drives the first bevel gear 17 to rotate, the first bevel gear 17 drives the second bevel gear 18 to rotate, the second bevel gear 18 drives the transmission rod 19 to rotate, the second transmission rod 19 drives the first scraper 20 to rotate, and the first scraper 20 drives the two second scrapers 21 to rotate. Thus, the first scraper 20 and the two second scrapers 21 can self-clean the inner wall of the boiler body 1, ensuring the service life of the electric boiler.
