Description

Technical Field

[0001] This utility model relates to the field of water flow switch and water flow metering, and more particularly to a pipe structure that integrates water flow switch and water flow metering. Background Technology

[0002] In the field of water heating or water electrolysis, a flow switch is usually installed to automatically cut off the power supply when the pipeline flow is abnormal (such as interruption or too low flow) to avoid equipment damage. In the fields of municipal water supply and drainage or agricultural irrigation, a flow meter is usually installed to monitor the water supply in real time, optimize water resource allocation, detect pipeline leakage, and reduce water waste.

[0003] However, the existing technology lacks a pipeline structure that integrates water flow switch and water flow meter, which results in a relatively simple pipeline structure function that cannot meet the needs of consumers. Utility Model Content

[0004] The main purpose of this utility model is to provide a pipe structure that integrates a water flow switch and water flow metering, which can effectively solve the problems in the background art. The pipe structure that integrates a water flow switch and water flow metering is equipped with a water flow switch component, which automatically starts when water flows through and then electrolyzes to produce ionized water. When no water flows through, it automatically shuts off and stops working. At the same time, it is also equipped with a water flow metering component, which can measure the flow of water.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A pipeline structure integrating a flow switch and a flow meter, including a main pipeline, a main control board, a flow switch assembly, and a flow metering assembly; The water flow switch assembly includes a piston, a first magnet, and a first detection element. The piston is located inside the main pipe, the first magnet is located inside the piston, and the first detection element is located on the main control board. The water flow metering component includes a deflector, a support, an impeller, and a second detection component. The deflector and the support are both located inside the main pipe and are connected. The impeller is rotatably located in the mounting cavity enclosed by the deflector and the support. The second detection component is located on the main control board.

[0006] Furthermore, based on the above solution, a reset component is also included. The reset component is used for the automatic reset of the piston and the first magnet. The reset component includes a second magnet, which is disposed on the reversing member and has the same pole on one end face opposite to the first magnet.

[0007] Furthermore, based on the above scheme, the reset assembly also includes an elastic element, which is disposed between the piston and the reversing element.

[0008] Furthermore, based on the above solution, a blocking part is provided on the inner wall of the main pipe, which is used to block the movement of the piston.

[0009] Furthermore, based on the above scheme, the deflector and the support are provided with sockets, the impeller is provided with a post, and the impeller is connected to the sockets of the deflector and the support through the post.

[0010] Furthermore, based on the above scheme, the deflector is provided with multiple oblique spiral guide vanes inside.

[0011] Furthermore, based on the above scheme, the outer wall of the main pipe is provided with a flat section.

[0012] Furthermore, based on the above solution, the support member is provided with at least one sealing ring, which is in contact with the inner wall of the main pipe.

[0013] Furthermore, based on the above scheme, the first detection component is a reed switch.

[0014] Furthermore, based on the above scheme, the second detection element is a Hall element.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model is equipped with a water flow switch assembly. When water flows into the main pipe, the water flow impacts the piston, causing the piston and the first magnet to move. When the first detection element detects the magnetic signal, the circuit is connected. When no water flows through the water flow switch, the first detection element does not detect the signal, the circuit is closed, and the operation stops. In this way, there is no need for the user to manually turn it on or off, reducing the inconvenience of operation for the user, avoiding waste of resources, and extending the service life of the equipment.

[0016] This utility model is equipped with a water flow metering component, which can monitor the water volume in real time. When the water flows into the main pipe and drives the impeller to rotate, the second detection element detects the change in the magnetic field of the impeller, thereby realizing the measurement of water flow.

[0017] This utility model integrates a water flow switch and a water flow meter, which can automatically start and stop the equipment and monitor the water volume in real time to meet the needs of consumers. Attached Figure Description

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0022] like Figure 1-3 As shown, the integrated water flow switch and water flow metering pipeline structure includes a main pipeline 1, a main control board 2, a water flow switch assembly, and a water flow metering assembly. The main pipeline 1 integrates the water flow switch and water flow metering, which can automatically start and stop the equipment and monitor the water volume in real time to meet the needs of consumers. Specifically, the water flow switch assembly includes a piston 301, a first magnet 302, and a first detection element 303. The piston 301 is located inside the main pipe 1 and can move downward within the main pipe 1 under the impact of water flow. The first magnet 302 is located inside the piston 301 and can move with the piston 301. The first detection element 303 is located on the main control board 2 and is used to detect the position of the first magnet 302. When the first magnet 302 enters the detection range of the first detection element 303, the first detection element 303 transmits a signal to the main control board 2, the main control board 2 controls the circuit and starts the equipment. When the first magnet 302 leaves the detection range of the first detection element 303, the first detection element 303 can no longer detect the first magnet 302, the main control board 2 controls the circuit and stops the equipment.

[0023] It is worth mentioning that the piston 301 is streamlined (bullet-shaped), that is, the upper part of the piston 301 has a small diameter and the lower part has a large diameter, and the piston 301 does not fit against the inner wall of the main pipe 1. This ensures that the water can flow out from the gap between the piston 301 and the main pipe 1.

[0024] In this embodiment, the first detection element 303 is a reed switch. When the first magnet 302 approaches, the reeds are magnetized and attract each other to close, thus connecting the circuit. After the magnetic field disappears, the reeds return to their elastic state and disconnect the circuit.

[0025] It should be noted that the first detection element 303 corresponds to the position of the piston 301 and the first magnet 302. That is, the movement path of the piston 301 and the first magnet 302 will coincide with the detection area of ​​the first detection element 303. This ensures that the first magnet 302 can enter the detection area of ​​the first detection element 303 and be detected by the first detection element 303.

[0026] In this embodiment, the detection area of ​​the first detection element 303 is 0-8mm upward from the center of the first detection element 303 and 0-8mm downward from the center of the first detection element 303. When the first magnet 302 enters this range, the first detection element 303 can detect the magnetic signal and connect the circuit.

[0027] The water flow metering component includes a deflector 401, a support 402, an impeller 403, and a second detection component 404. The deflector 401 and the support 402 are both located inside the main pipe 1 and are connected to each other. The deflector 401 and the support 402 are fitted into the interior of the main pipe 1. The deflector 401 and the support 402 are connected end to end and have an internal mounting cavity for mounting the impeller 403. The impeller 403 is rotatably located in the mounting cavity enclosed by the deflector 401 and the support 402. The second detection component 404 is located on the main control board 2.

[0028] In this embodiment, the impeller 403 is a plastic magnetic impeller 403 with a permanent magnet embedded inside, and the second detection element 404 is a Hall element. When the water flow drives the impeller 403 to rotate, the direction of the magnetic field changes periodically. The Hall element converts the rotation of the impeller 403 into an electrical pulse signal based on the change of the magnetic field, and then calculates the water flow velocity and flow rate.

[0029] It is important to note that the impeller 403 and the second detection element 404 must be aligned to ensure that the second detection element 404 can accurately detect the magnetic field changes caused by the rotation of the impeller 403.

[0030] The deflector 401 and the support 402 are provided with a socket 405, and the impeller 403 is provided with a post 406. The post 406 can be inserted into the socket 405, and the impeller 403 is connected to the socket 405 of the deflector 401 and the support 402 through the post 406.

[0031] In this embodiment, since the impeller 403 is a straight-bladed impeller 403, it is necessary to change the direction of the water flow. The deflector 401 is provided with multiple oblique spiral guide vanes 407. The water flow is guided by the spiral guide vanes 407, causing the water flow to flow obliquely and generate vortices so that the water flow can impact the blades of the impeller 403, thereby driving the impeller 403 to rotate. The Hall element converts the rotation of the impeller 403 into an electrical pulse signal, thereby calculating the water flow velocity and flow rate.

[0032] In this embodiment, the outer wall of the main pipe 1 near the main control board 2 is provided with a flattened part 102, which is a cut surface, which can make the wall thickness of the main pipe 1 thinner at this point. At the same time, the first detection element 303 and the second detection element 404 are provided on the side of the main control board 2 closer to the main pipe 1, so that the first detection element 303 and the second detection element 404 can detect signals.

[0033] The support 402 is provided with two sealing rings 6, which are in contact with the inner wall of the main pipe 1 and play a sealing role.

[0034] The integrated water flow switch and water flow metering pipe structure also includes a reset component. The reset component is used for the automatic reset of piston 301 and first magnet 302. When piston 301 loses the impact force of water flow, piston 301 and first magnet 302 can automatically reset under the action of the reset component, so that first magnet 302 leaves the detection area of ​​first detection element 303 and disconnects the circuit. The reset component includes a second magnet 501. The second magnet 501 is disposed on the direction changer 401, and the end face opposite to the first magnet 302 has the same pole, which can be the same N pole or S pole. By utilizing the repulsion of the like poles of the magnets, piston 301 can be lifted. At the same time, a blocking part 101 is provided on the inner wall of the main pipe 1. The blocking part 101 is used to block piston 301 from moving. When there is no water flow in the main pipe 1, piston 301 rises and resets under the action of the repulsion of the like poles of the magnets, and is blocked by the blocking part 101, so that piston 301 stops at the blocking part 101.

[0035] The reset assembly also includes an elastic element 502, which is located between the piston 301 and the reversing element 401. The elastic element 502 plays an auxiliary role in reset. When the repulsive force of the magnet is insufficient, the elastic element 502 can also move the piston 301 upward to reset.

[0036] It is worth mentioning that the reset mechanism also plays a balancing role. When the piston 301 and the first magnet 302 move downward due to the impact of the water flow, the reset mechanism will give the piston 301 and the first magnet 302 an upward force, so that the piston 301 and the first magnet 302 remain stable and always within the detection range of the first detection element 303, and the circuit is always in the on state.

[0037] In this embodiment, the elastic element 502 is a spring.

[0038] like Figure 4-6 As shown, this is a silver ion generator that uses the present invention. It has an internal pipe structure that integrates a water flow switch and a water flow meter. At the same time, an electrolysis mechanism 7 is provided above the pipe structure that integrates the water flow switch and the water flow meter. A silver sheet is provided on the electrolysis mechanism and extends into the main pipe 1.

[0039] The silver ion generator is connected to the water circuit, with the upper end being the inlet and the lower end being the outlet. When the water circuit supplies water, the water flows in through the inlet and first impacts the piston 301. The piston 301 and the first magnet 302 are lowered by the force. When the first magnet 302 enters the detection area of ​​the first detection element 303, the first detection element 303 detects a magnetic signal, the circuit is connected, the dry cell battery 8 provides power, and the electrolysis mechanism 7 electrolyzes to generate silver ions. When the water supply stops, the piston 301 and the first magnet 302 will rise and reset under the action of the second magnet 501 and the elastic element 502. When the second magnet 501 leaves the detection area of ​​the first detection element 303, the first detection element 303 can no longer detect a magnetic signal, the circuit is disconnected, and the dry cell battery 8 stops supplying power. When the water flows through the deflector 401, it generates a vortex that impacts the impeller 403. The impeller 403 rotates, and the second detection element 404 converts the magnetic field change generated by the rotation of the impeller 403 into an electrical pulse signal, which is then used by the system to calculate the water flow velocity and flow rate.

[0040] It should be noted that all standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
