[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The embodiment of the present application solves the problem of a water level sensor being covered with scale and a water replenishment control device having no safety protection by providing a boiler water pump continuous water replenishment control device. When in use, the water level sensor is free of scale adhesion and the safety factor of the boiler in use is improved.

[0027] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0028] A water tank is connected to the boiler body and the height of the water tank is consistent with the height of the boiler body. The water level in the boiler can be reflected in the water tank. The water level in the boiler body can be adjusted by adjusting the water level in the water tank. A floating ball is arranged inside the water tank, and the floating ball is connected to the fixed rod and the limit plate. When the water level reaches a certain height, the limit plate contacts the top of the water tank to generate pressure. The power-off and power-on of the water pump are directly controlled by the pressure sensor. At the same time, the pressure sensor is connected to an alarm to remind users of instrument abnormalities.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 2 A boiler water pump 12 continuous water replenishment control device comprises: a boiler body 1 and a water tank 2, the boiler body 1 and the water tank 2 are connected by a U-shaped tube 3; a base 4 is connected to the bottom of the water tank 2, a plurality of water level sensors 5 are connected to the water tank 2, an air vent 6 is provided at the top of the water tank 2, a fixing rod 7 is connected to the air vent 6, the fixing rod 7 is slidably connected to the top of the water tank 2 through the air vent 6, a floating ball 8 is connected to the bottom of the fixing rod 7, two limit plates 9 are connected to the fixing rod 7, a plurality of pressure sensors 10 are arranged on the top of the water tank 2, the pressure sensor 10 is connected to an alarm 11 and a water pump 12, a plurality of water level sensors 5 are connected to a controller 13, the controller 13 is electrically connected to the water pump 12, the water pump 12 is connected to a water inlet pipe 14, and one end of the water inlet pipe 14 is connected to the upper part of the water tank 2.

[0031] A water tank 2 is connected to the boiler body 1 and the height of the water tank 2 is consistent with the height of the boiler body 1. The water level in the boiler can be reflected in the water tank 2. The water level in the water tank 2 can be adjusted to adjust the water level in the boiler body 1. A floating ball 8 is arranged inside the water tank 2. The floating ball 8 connects the fixed rod 7 and the limit plate 9. When the water level reaches a certain height, the limit plate 9 contacts the top of the water tank 2 to generate pressure. The pressure sensor 10 directly controls the power-off and power-on of the water pump 12. At the same time, the pressure sensor 10 is connected to the alarm 11 to remind the user of instrument abnormalities.

[0032] One end of the U-shaped tube 3 passes through the boiler body 1 , and a section of the U-shaped tube 3 located inside the boiler body 1 is parallel to the inner side of the boiler body 1 and opens upward.

[0033] A section of the U-shaped tube 3 located inside the boiler body 1 is parallel to the inner side of the boiler body 1 and opens upward to ensure that the gas generated by the boiler does not enter the U-shaped tube 3. At the same time, the cold water flowing out of the U-shaped tube 3 cannot directly contact the heating part at the bottom of the boiler, thereby protecting the stable operation of the boiler.

[0034] The other end of the U-shaped tube 3 is connected to the bottom of the water storage tank 2 , and a check valve 15 is arranged in the middle of the U-shaped tube 3 .

[0035] The check valve 15 can prevent the hot water in the boiler from flowing back into the water tank 2, thereby protecting the water tank 2. The other end of the U-shaped tube 3 is connected to the bottom of the water tank 2 to improve the circulation of water in the water tank 2 and reduce water accumulation.

[0036] The water level sensor 5 passes through the inner wall of the water tank 2 and is fixedly connected to the water tank 2 , and a plurality of water level sensors 5 are evenly distributed on one side of the water tank 2 .

[0037] Multiple water level sensors can accurately measure the water level in the water storage tank and improve detection sensitivity.

[0038] The multiple pressure sensors 10 are located on the inner side of the top of the water tank 2 and the outer side of the top of the water tank 2 , and the multiple pressure sensors 10 are arranged around the air vent 6 .

[0039] Reference Figure 2 One limiting plate 9 is located at the top of the fixing rod 7 , and the other limiting plate 9 is located below the fixing rod 7 and does not contact the floating ball 8 .

[0040] When the controller 13 and the water level sensor 5 fail, the water level rises and the floating ball 8 drives the fixed rod 7 to rise. When the water level exceeds the set water level, the limit plate 9 presses the pressure sensor 10 located on the inner side of the top of the water tank 2. The pressure sensor 10 is connected to the water pump 12 to shut down the water pump 12 and stop water intake. When the water level drops, the floating ball 8 drops, driving the fixed rod 7 to drop. When the water level is lower than the set water level, the limit plate 9 presses the pressure sensor 10 located on the outer side of the top of the water tank 2. The pressure sensor 10 is connected to the water pump 12 to start the water pump 12 and start water supply. When the pressure sensor 10 senses pressure, the alarm 11 will be directly activated to warn the user to check the fault. The alarm 11 is adjacent to the water pump 12, and the top of the water tank 2 is flush with the top of the boiler body 1.

[0041] The alarm 11 is adjacent to the water pump 12 to remind the user to check the operation of the water pump 12 as soon as possible to determine whether the water pump 12 has failed. The top of the water tank 2 is flush with the top of the boiler body 1 to ensure that the water level inside the water tank 2 is consistent with the water level in the boiler body 1.

[0042] During use, the water pump delivers water to the water tank through the water inlet pipe, and the water level sensor sends the water level information to the controller in real time. The controller controls the flow rate of the water pump. When the controller and the water level sensor fail, the water level rises and the floating ball drives the fixed rod to rise. When the water level exceeds the set water level, the limit plate presses the pressure sensor located on the inside of the top of the water tank. The pressure sensor is connected to the water pump to shut down the water pump and stop water intake. When the water level drops, the floating ball drops, driving the fixed rod to drop. When the water level is lower than the set water level, the limit plate presses the pressure sensor located on the outside of the top of the water tank. The pressure sensor is connected to the water pump to start the water pump and start supplying water. When the pressure sensor senses pressure, the alarm will be directly activated to alert the user to check for faults.

[0043] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The water level in the water tank can be kept consistent with the water level in the boiler body through the U-shaped tube. The water level in the boiler body can be adjusted by adjusting the water level in the water tank, and the influence of scale on the water level sensor can be eliminated at the same time.

[0045] 2. It has alarm and can directly shut down and start the water pump to ensure that the water level in the boiler is maintained at a normal level, increasing the safety of boiler operation.
