Description

Technical Field

[0001] This invention relates to the field of water pump control technology, and more specifically, to an intelligent water pump controller. Background Technology

[0002] The water pump controller starts and stops the water pump based on data such as detected water source status, water consumption in the pipeline, and changes in pipeline pressure. It can be a traditional system consisting of a pressure tank, pressure switch, water shortage protection device, check valve, four-way valve, etc. The complete isolation of live parts from the pipeline and the highly sealed control box give this controller a level of safety unmatched by traditional systems.

[0003] The evolution of water pump control technology hinges on the continuous upgrading of control methods and precision. Its development follows a path of "manual – semi-automatic – automatic – intelligent." From initially relying on manual start-up and shutdown, to achieving semi-automatic or automatic start-up and shutdown after adding pressure tanks and pressure switches, current water pump control is still not intelligent enough. A more comprehensive controller is needed to achieve intelligent start-up and shutdown of water pumps. Therefore, this application provides an intelligent water pump controller to meet this need. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide an intelligent water pump controller. Through a magnet, pressure diaphragm, copper float assembly, and a reed switch on a circuit board, the controller controls the start and stop of the water pump when the flow rate and pressure change, thereby achieving intelligent control of the water pump and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A smart water pump controller includes a housing, a function panel at the bottom of the housing, a circuit board at the top of the function panel, the circuit board inside the housing, a casing outside the circuit board, a water inlet on one side of the housing, a one-way valve core inside the water inlet, a middle body inside the housing, a lower positioning rod inside the housing, a head body fixedly connected to the top of the housing, a head cap assembly at the top of the head body, a spring inside the head body, an upper positioning rod inside the head body, the upper positioning rod inside the spring, a pressure diaphragm at the bottom of the head body, a water outlet on the side of the housing away from the water inlet, a copper float assembly inside the water outlet, a flow magnet outside the copper float assembly, a pressure magnet inside the lower positioning rod, and a reed switch inside the circuit board for use with the copper float assembly and the flow magnet.

[0007] In the above technical solution, a connecting component is provided at one end of the water inlet, a supporting and fixing component is provided on the outside of the connecting component, and a limiting component is provided at one end of the water outlet.

[0008] In the above technical solution, the connecting assembly further includes a fastening screw sleeve that is rotatably sleeved on the outside of the water inlet end. The inner side of the fastening screw sleeve is threaded with a connecting pipe, and one end of the connecting pipe is threaded with a connector. The outer side of the fastening screw sleeve is rotatably connected with a movable collar, and the outer side of the movable collar is fixedly connected with two connecting blocks, which are arranged in an axially symmetrical manner.

[0009] In the above technical solution, the support and fixing assembly further includes two connectors sleeved on the outside of the movable collar and the connecting block. The two connectors are arranged in an axially symmetrical manner. The inner contours of the two connectors match the outer contours of the movable collar and the connecting block. Both ends of the two connectors are inserted with first bolts, which are inserted into the inner side of the connecting block.

[0010] In the above technical solution, further, a support arm is fixedly connected to the outer side of each of the two connecting parts, a first stud is rotatably connected to the inside of the support arm, a support sleeve is threadedly connected to the outer side of the first stud, and the support sleeve is slidably connected to the inner side of the support arm.

[0011] In the above technical solution, the bottom of the support sleeve is rotatably connected to a transmission screw sleeve, the inner side of the support sleeve is slidably connected to a support column, the transmission screw sleeve and the support column are threadedly connected, and the bottom end of the support column is fixedly connected to a support base.

[0012] In the above technical solution, the top of the support arm is hinged to a fixing frame, the fixing frame is arranged in an abutting position with the housing, and the top of the support arm is rotatably connected to a second stud.

[0013] In the above technical solution, the outer side of the second stud is threaded with a fixed cross post, and the outer side of the fixed cross post is fitted with a limiting sleeve, which is slidably connected to one side of the fixed frame.

[0014] In the above technical solution, the limiting component further includes two limiting outer brackets sleeved on one end of the water outlet. The inner diameter of the limiting outer brackets is larger than the outer diameter of the water outlet. The bottom ends of the two limiting outer brackets are fixedly connected to a support base, and the two sides of the two limiting outer brackets are each inserted with a second bolt.

[0015] The technical effects and advantages of this invention are as follows:

[0016] This invention utilizes two magnets, a pressure diaphragm, a copper float assembly, and a reed switch for operation. Magnetic force causes the reed switch's reed to close or open, triggering a circuit signal to control the start and stop of the water pump. Similarly, when the pressure inside the pipeline changes, the pressure diaphragm and the pressure magnet are linked, causing the pressure magnet to shift closer to or further from the reed switch, thereby controlling the start and stop of the water pump. This makes the controller more proactive and intelligent.

[0017] This invention, through the support and fixing components and the limiting components, can improve the support force on the controller and the water supply pipeline, ensure stable connection, and reduce the load on the inlet and outlet ends. This ensures the support capacity of the controller and the water supply pipeline under extreme use conditions, and avoids the phenomenon of breakage of the inlet and outlet ends due to excessive load, which would reduce the service life.

[0018] By using connecting components, various water pumps can be adapted for connection. When adapting to multiple water pumps, only the connector needs to be replaced, which can significantly reduce the adaptation cost. Furthermore, the water inlet end and the fastening screw sleeve are rotatably connected, so the housing can be adjusted before tightening to determine the orientation of the function panel. This allows the function panel to be oriented in a more convenient direction, thus solving the problem that the orientation of the function panel cannot be flexibly adjusted during the current installation of the controller, thereby improving the installation flexibility of the controller.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Refer to the instruction manual appendix Figures 1-9 As shown, an intelligent water pump controller according to an embodiment of the present invention includes a housing 15. A function panel 1 is provided at the bottom of the housing 15, and a circuit board 2 is provided at the top of the function panel 1. The circuit board 2 is disposed inside the housing 15, and a housing 3 is provided outside the circuit board 2. A water inlet 16 is provided on one side of the housing 15, and a one-way valve core 4 is provided inside the water inlet 16. A middle body 5 is provided inside the housing 15, and a lower positioning rod 6 is provided inside the housing 15. A head body 7 is fixedly connected to the top of the housing 15, and a head cap is provided on the top of the head body 7. The inner side of the head body 7 is provided with a spring 9 and an upper positioning rod 10. The upper positioning rod 10 is located inside the spring 9. A pressure diaphragm 11 is provided at the bottom of the head body 7. A water outlet 17 is provided on the side of the housing 15 away from the water inlet 16. A copper float assembly 12 is provided inside the water outlet 17. A flow magnet 13 is provided outside the copper float assembly 12. A pressure magnet 14 is provided inside the lower positioning rod 6. A reed switch that works with the copper float assembly 12 and the flow magnet 13 is provided inside the circuit board 2.

[0031] A connecting component is provided at one end of the water inlet 16, and a supporting and fixing component is provided on the outside of the connecting component. A limiting component is provided at one end of the water outlet 17.

[0032] It should be noted that when the flow rate or water level in the pipeline changes, the flow magnet 13 inside the copper float assembly 12 is displaced, moving closer to or away from the reed switch. Through magnetic force, the reed switch's reed closes or opens, thereby triggering a circuit signal to control the start and stop of the water pump. Similarly, when the pressure in the pipeline changes, the pressure diaphragm 11 and the pressure magnet 14 are linked, causing the pressure magnet 14 to displace, moving closer to or away from the reed switch, thereby controlling the start and stop of the water pump. It also has a water shortage protection function and can automatically detect whether there is water in the pipeline according to a set time, such as two hours. This step can also be achieved by pressing the "reset" button on the function panel 1, which can significantly improve the intelligence of the controller.

[0033] Furthermore, the connecting assembly includes a fastening sleeve 18 rotatably fitted onto the outside of the water inlet end 16. A connecting pipe 19 is threadedly connected to the inner side of the fastening sleeve 18. A sealing element is provided at one end of the connecting pipe 19 near the water inlet end 16 to achieve a seal between the water inlet end 16 and the connecting pipe 19. A connector 20 is threadedly connected to one end of the connecting pipe 19. A movable collar 21 is rotatably connected to the outside of the fastening sleeve 18. Two connecting blocks 22 are fixedly connected to the outside of the movable collar 21. The two connecting blocks 22 are arranged in an axially symmetrical manner.

[0034] It should be noted that when connecting the controller to the water pump, the connector 20 is connected to the outlet end of the water pump and secured. Since the connector 20 and the connecting pipe 19 are threaded, they can be separated. This separate design of the connecting pipe 19 and connector 20 allows for easy replacement of the connector 20 if the water pump thread does not match, thus adapting to various water pumps. During connection, both ends of the connector 20 must be sealed. After connecting the connector 20 to the water pump, the fastening sleeve 18 is rotated. Since the fastening sleeve 18 can only rotate outside the inlet end 16, rotating the fastening sleeve 18 will cause the connecting pipe 19 to move closer to the inlet end 16. The connecting pipe 19 is fitted to the water inlet 16, and a sealing element is provided at one end of the connecting pipe 19 near the water inlet 16. The contact between the connecting pipe 19 and the water inlet 16 and the sealing element keeps the water inlet 16 sealed, thus completing the connection between the controller and the water pump. Since the water inlet 16 and the fastening sleeve 18 are rotatably connected, the water inlet 16 can be rotated before the connecting pipe 19 contacts the water inlet 16 when the fastening sleeve 18 is tightened. This allows the orientation of the function panel 1 to be adjusted so that the function panel 1 can face the desired and more convenient direction. This solves the problem that the orientation of the function panel 1 cannot be flexibly adjusted when installing the controller, thereby improving the flexibility of controller installation.

[0035] Furthermore, the support and fixing assembly includes two connectors 23 sleeved on the outside of the movable collar 21 and the connecting block 22. The two connectors 23 are arranged in an axially symmetrical manner. The inner contours of the two connectors 23 match the outer contours of the movable collar 21 and the connecting block 22. Both ends of the two connectors 23 are inserted with first bolts 24. The two connectors 23 are fixedly connected to the movable collar 21 by the first bolts 24. The two connectors 23 rotate on the outside of the fastening sleeve 18 through the movable collar 21. The first bolts 24 are inserted into the inside of the connecting block 22.

[0036] Support arms 25 are fixedly connected to the outer sides of both connectors 23. A first stud 26 is rotatably connected to the inside of the support arm 25. A support sleeve 27 is threadedly connected to the outer side of the first stud 26. The support sleeve 27 is slidably connected to the inner side of the support arm 25. A transmission sleeve 28 is rotatably connected to the bottom of the support sleeve 27. A support column 29 is slidably connected to the inner side of the support sleeve 27. The transmission sleeve 28 and the support column 29 are threadedly connected. A support base 30 is fixedly connected to the bottom end of the support column 29. The support base 30 is made of rubber. A square-shaped limiting post is provided on the inner side of the support sleeve 27. The support column 29 slides on the outer side of the limiting post. The limiting post limits the support column 29, so that the support column 29 can only slide up and down on the inner side of the support sleeve 27.

[0037] A fixing frame 31 is hinged to the top of the support arm 25. The fixing frame 31 is in contact with the housing 15. A second stud 32 is rotatably connected to the top of the support arm 25. The second stud 32 is located inside the fixing frame 31. A fixing cross post 33 is threaded to the outside of the second stud 32. The fixing cross post 33 is in contact with the fixing frame 31. A limiting sleeve 34 is sleeved on the outside of the fixing cross post 33. The limiting sleeve 34 is slidably connected to one side of the fixing frame 31.

[0038] It should be noted that, after the controller and water pump are connected, the two connecting pieces 23 are sleeved on the outside of the movable collar 21 and the connecting block 22, and the two connecting pieces 23 are fixedly connected to the movable collar 21 and the connecting block 22 by the first bolt 24. After the two connecting pieces 23 are fixed, the first studs 26 on both sides are rotated to move the support sleeves 27 on both sides accordingly, and the support base 30 is adjusted to the optimal position on the top of the water pump to ensure that the support base 30 is in a relatively horizontal state after contacting the water pump. At this time, the transmission screw sleeve 28 is rotated to lower the support column 29 until the support base 30 contacts the top of the water pump and is secured. Since the support base 30 is made of rubber, it can not only provide support when in contact with the water pump, but also deform accordingly to adapt to the outer contour of the water pump when the surface of the water pump is not flat.

[0039] Since the limiting sleeve 34 is slidably connected to one side of the fixed frame 31, it can limit the fixed cross column 33 and prevent the fixed cross column 33 from rotating. When the second studs 32 on both sides are rotated, the fixed cross column 33 will rise and fall accordingly. At the same time, during the rising and falling of the fixed cross column 33, it will drive the fixed frame 31 to rotate accordingly, thereby adjusting the contact between the fixed frame 31 and the housing 15. The fixed frame 31 supports the housing 15 by contacting it. After the above settings are completed, the controller can be supported by the supporting fixing components. This can solve the problem that some controllers have a long connection distance with the water pump, which leads to unstable controller support. In addition, the controller outlet is connected to a long rigid pipe, which causes the controller to bear a large load, resulting in the breakage of the controller's inlet end 16 or outlet end 17.

[0040] Furthermore, since the connector 23 can rotate on the outside of the fastening sleeve 18 via the movable collar 21, and can be adjusted as needed, the fixing bracket 31 can fit against both sides of the housing 15, so that the support fixing component can be adapted to the orientation of the housing 15. Moreover, the connector 23 and the movable collar 21 are separable, so that it can be determined whether the support fixing component needs to be installed according to actual needs during use, so that it can be selected according to actual needs, thereby meeting various needs during actual use.

[0041] Furthermore, the limiting assembly includes two limiting outer brackets 35 sleeved on one end of the water outlet 17. The inner diameter of the limiting outer brackets 35 is larger than the outer diameter of the water outlet 17. The bottom ends of the two limiting outer brackets 35 are fixedly connected to a support base 36. The two sides of the two limiting outer brackets 35 are each inserted with a second bolt 37.

[0042] It should be noted that, after connecting the water outlet pipe to the water outlet end 17, two limiting outer supports 35 are fitted onto the outside of the water outlet pipe joint and the water outlet end 17. The two limiting outer supports 35 and the water outlet pipe joint are interference fit, and the inner contour can be set according to the outer contour of the water supply pipe joint. This ensures that the two limiting outer supports 35 can fit snugly onto the outside of the water supply pipe joint. They are then fixed with two sets of second bolts 37 to ensure that the two limiting outer supports 35 are securely fitted onto the outside of the water supply pipe joint and the water outlet end 17, guaranteeing the stability of the two limiting outer supports 35. The limiting bracket 35 is used to clamp and support the water pipe. When installing the limiting bracket 35, it is also necessary to ensure that the support base 36 can contact the top of the housing 15. The bottom and inner contour of the support base 36 are adapted to the contour between the housing 15 and the water outlet 17. In this way, the limiting bracket 35 and the support base 36 can support the water pipe, improve the support force of the housing 15 on the water pipe, and provide good support force through the limiting component when the water pipe is long, reduce the load on the water outlet 17, and thus avoid the phenomenon of breakage due to excessive load on the water outlet 17.

[0043] In summary, by using the support and fixing components and the limiting components, the support force on the controller and the water supply pipeline can be improved, ensuring a stable connection while reducing the load on the inlet end 16 and the outlet end 17. This ensures the support capacity for the controller and the water supply pipeline under extreme operating conditions and prevents the inlet end 16 and the outlet end 17 from breaking due to excessive load, thus reducing their service life.
