However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a smart water meter with a detachable filter structure, including a smart water meter body 1, an inlet pipe 2 fixedly connected to one side of the smart water meter body 1, an outlet pipe 3 fixedly connected to the other side of the smart water meter body 1, a smart meter box 4 installed on the upper outer wall of the smart water meter body 1, a filter mechanism 5 installed in the middle of the inlet pipe 2, the filter mechanism 5 including a sealing box 51, a mounting groove 52, a top cover 53, bolts 54 and a filter screen 55, the mounting groove 52 is opened on the top surface of the sealing box 51, the top cover 53 is installed on the inner wall of the mounting groove 52, a flow groove 21 is provided inside the inlet pipe 2, the inside of the mounting groove 52 is connected to the inside of the flow groove 21, the top cover 53 is connected and fixed to the mounting groove 52 by bolts 54, the filter screen 55 is set inside the mounting groove 52, and the top surface of the filter screen 55 is fixedly connected to the bottom surface of the top cover 53.

[0021] The specific settings and functions of this embodiment are described below. The sealing box 51 and the water inlet pipe 2 are fixed by welding to form an independent filter chamber. The filter screen 55 is completely embedded in the installation groove 52 to completely filter the water flowing into the water inlet pipe 2. The filter screen disassembly and assembly time is effectively shortened by setting the top cover 53 and bolts 54, and there is no need to disassemble the main body of the water meter. The water outage time is controlled within 10 minutes, which is suitable for high-rise residential buildings and other scenarios with high requirements for water supply continuity.

[0022] Example 2: Figure 1 - Figure 3As shown, the filter mechanism 5 also includes a fixed rod 56, a shrinkage groove 57, a baffle 58, and a movable groove 59. The shrinkage groove 57 is formed in the inner wall of the sealed box 51. The baffle 58 is movably connected to the inner wall of the shrinkage groove 57. The bottom end of the fixed rod 56 is fixedly connected to the top surface of the baffle 58. The fixed rod 56 passes through the top surface of the shrinkage groove 57 and is in contact with the bottom surface of the top cover 53. The movable groove 59 is located above the shrinkage groove 57, and a pulling block is movably connected to the inner wall of the movable groove 59. 592, a spring 591 is fixedly connected to the top surface of the pulling block 592, and the top of the spring 591 is fixedly connected to the top surface inside the movable groove 59.

When the top cover 53 is removed, the fixing rod 56 loses pressure, and the spring 591 returns to its original position and contracts, causing the pulling block 592 to drive the baffle 58 to rise and close the flow groove 21, thereby achieving flow interruption protection and preventing water from overflowing from the pipeline during maintenance. This also makes it easier for operators to disassemble and maintain the filter screen 55.

[0024] The device is used and works as follows: Tap water enters the flow channel 21 through the inlet pipe 2. It first passes through the filter screen 55 to intercept impurities such as mud, sand and rust. The filtered water flows through the connecting channel 13 to drive the impeller metering mechanism 14 to rotate. The metering data is processed by the display head 11 and uploaded to the smart meter box 4. The filter screen disassembly and assembly time is effectively shortened by setting the top cover 53 and bolts 54, and there is no need to disassemble the water meter body. When the top cover 53 is disassembled, the fixing rod 56 loses pressure, the spring 591 returns to its original position and contracts, causing the pulling block 592 to drive the baffle 58 to rise and close the flow channel 21, thus achieving flow interruption protection.
