[0030] See also Figure 1-Figure 5 The present invention provides a flow-measurable electric shock wall device 100. The flow-measurable electric shock wall device 100 accurately measures water flow data and transmits the measured flow data to a controller, enabling the controller to implement precise program control based on the flow data. To achieve the above technical objectives, the flow-measurable electric shock wall device 100 includes an electric shock wall body 10 and a flow detection device 20. The specific structure is described as follows:

[0031] The main body 10 of the anti-electricity barrier is provided with a water inlet pipe 11, which can be specifically located on the lower side of the main body 10. Water flows into the main body 10 through the water inlet pipe 11. The main body 10 of the anti-electricity barrier is made of an insulating material, preferably a hydrophilic insulating material such as PPR, PA, or PP, and has an internal water channel.

[0032] The flow detection device 20 includes a magnetic rotor guide tube 21 and a Hall sensor 22. The magnetic rotor guide tube 21 is embedded in the anti-electricity wall body 10 through the water inlet pipe 11. The Hall sensor 22 is provided on the anti-electricity wall body 10 and is electrically connected to a controller. Specifically, the magnetic rotor guide tube 21 is embedded and fixed in the anti-electricity wall body 10. Under the impact of the water flow, the magnetic rotor 212 inside the magnetic rotor guide tube 21 rotates. The Hall sensor 22 collects rotation data of the magnetic rotor 212, calculates flow data based on the rotation data, and transmits the flow data to a controller, which can specifically be the controller of the electric water heater 200, so that the controller can achieve precise program control based on the flow data.

[0033] In the technical solution of the embodiment of the present utility model, a flow-measuring anti-electricity wall device 100 includes an anti-electricity wall body 10 and a flow detection device 20. The anti-electricity wall body 10 is provided with a water inlet pipe 11. The flow detection device 20 includes a magnetic rotor guide tube 21 and a Hall effect sensor 22. The magnetic rotor guide tube 21 is embedded in the anti-electricity wall body 10 through the water inlet pipe 11. The Hall effect sensor 22 is provided on the anti-electricity wall body 10 and is electrically connected to a controller. The flow detection device 20 can accurately measure water flow data and transmit the measured flow data to the controller, thereby enabling the controller to implement precise program control based on the flow data.

For example, in this embodiment, the Hall sensor 22 is fixed to the housing of the anti-electricity wall main body 10 via screws. Specifically, the housing of the Hall sensor 22 and the housing of the anti-electricity wall main body 10 are both provided with screw holes, and the screws are screwed into the screw holes of the housing of the Hall sensor 22 and the housing of the anti-electricity wall main body 10 in sequence to achieve the fixing of the Hall sensor 22 to the housing of the anti-electricity wall main body 10.

[0035] Furthermore, the magnetic rotor guide tube 21 includes a cylinder 211 and a magnetic rotor 212. The magnetic rotor 212 is rotatably connected to the cylinder 211. When fluid flows through the cylinder 211, the magnetic rotor 212 is driven to rotate. The magnetic rotor 212 is magnetic, and the Hall sensor 22 can detect the rotation data of the magnetic rotor 212 to further obtain water flow data.

[0036] Furthermore, the flow-measurable electric shock wall device 100 also includes an inner tube 30. A circuitous waterway 40 is provided within the electric shock wall body 10. One end of the inner tube 30 is embedded within the circuitous waterway 40, and the other end of the inner tube 30 is connected to the magnetic rotor guide tube 21. During installation, the inner tube 30 is first embedded within the electric shock wall body 10 through the water inlet pipe 11, and the magnetic rotor guide tube 21 is then embedded within the electric shock wall body 10 through the water inlet pipe 11. The inner tube 30 is made of an insulating material, preferably a hydrophilic insulating material such as PPR, PA, or PP.

[0037] Furthermore, the circuitous waterway channel 40 includes a first channel section 41, a second channel section 42, and a third channel section 43 that are connected in sequence, wherein the second channel section 42 turns back from the outlet of the first channel section 41 to the inlet of the first channel section 41 and then connects to the third channel section 43. Specifically, one end of the inner tube 30 is embedded in the first channel section 41. The second channel section 42 turns back from the outlet of the first channel section 41 to the inlet of the first channel section 41 and then connects to the third channel section 43. The third channel section 43 is then arranged along the inlet of the first channel section 41 toward the outlet of the first channel section 41. By the above-mentioned circuitous arrangement of the first channel section 41, the second channel section 42, and the third channel section 43, the length of the circuitous waterway channel 40 can be effectively shortened, thereby facilitating the miniaturization design of the flow-measurable electric wall device 100.

[0038] Furthermore, a first interlocking groove 12 is provided on the lower side of the anti-electricity wall main body 10, and the anti-electricity wall device 100 capable of measuring flow also includes a first interlocking joint 50, the first interlocking joint 50 is embedded in the first interlocking groove 12, and the first interlocking joint 50 is sleeved on the outer side of the water inlet pipe portion 11. In a specific implementation, the water inlet pipe portion 11 is provided on the lower side of the anti-electricity wall main body 10, and the first interlocking groove 12 is provided around the outer periphery of the water inlet pipe portion 11. The first interlocking joint 50 is embedded in the first interlocking groove 12, and the first interlocking joint 50 is sleeved on the outer side of the water inlet pipe portion 11. The first interlocking joint 50 can be specifically an external threaded joint, which is provided with an external thread. Furthermore, in order to avoid water leakage, a sealing ring is provided between the first interlocking joint 50 and the first interlocking groove 12.

[0039] Furthermore, the upper side of the electric shock barrier body 10 is provided with a second interlocking groove 13 and a water outlet pipe 14 extending through and outside the second interlocking groove 13. The electric shock barrier device 100 with flow measurement capability also includes a second interlocking joint 60, which is interlocked within the second interlocking groove 13, and through which the water outlet pipe 14 passes. Specifically, the water outlet pipe 14 is provided on the upper side of the electric shock barrier body 10, with the second interlocking groove 13 surrounding the outer circumference of the water outlet pipe 14. The second interlocking joint 60 is interlocked within the second interlocking groove 13, and through which the water outlet pipe 14 passes. The second interlocking joint 60 is an internally threaded joint with internal threads, and a gap is provided between the water outlet pipe 14 and the second interlocking joint 60. Furthermore, to prevent water leakage, a sealing ring is provided between the second interlocking joint 60 and the second interlocking groove 13.

[0040] Furthermore, in the embodiment of the present invention, at least a portion of the circuitous water channel 40 is within the water outlet pipe portion 14 .
