The internal component 2 includes an embedded groove 201, a recess 202 is opened at the top of the embedded groove 201, and a sealing ring 203 is provided inside the recess 202. The top component 3 includes a sealing cover 301, a viewing window 302 is opened at the top of the sealing cover 301, two pull rods 303 are installed on the outer wall of the sealing cover 301, two slots 304 are opened on one side of the two pull rods 303, and a sealing groove 305 is opened at the bottom of the sealing cover 301.

[0027] The effect achieved by the entire embodiment 1 is that a special rubber sealing ring 203 is used to seal the connection between the main body and the top component 3. This sealing ring 203 has good elasticity and corrosion resistance, and can fit tightly against the connection surface of the two parts, preventing water and water vapor from entering the electronic parts and ensuring the normal operation of the electronic components. The valve control device in the water meter body 101 is crucial for the sealing performance and maintains good sealing performance. Open the sealing valve 102, squeeze the sealing air bag 103 to inflate the inside of the sealing ring 203, and close the sealing valve 102 after it is full of air. The multiple reinforcing ribs 205 provide stable support for the water meter body 101.

[0028] Example 2, as Figures 1-5As shown, the outer wall of the water meter body 101 is provided with two fixed blocks 104, which are fixedly installed on the water meter body 101 and provided with two movable buckles 105 on one side, which are movably connected with the two fixed blocks 104. The sealing valve 102 is movably connected with the sealing air bag 103. The inner part of the embedded groove 201 is provided with a metal shielding layer 204, which is embeddedly connected with the embedded groove 201. The metal shielding layer 204 is embeddedly connected with the embedded groove 201. The sealing ring 203 is embeddedly connected with the embedded groove 201. The inner part of the embedded groove 201 is provided with a plurality of reinforcing ribs 205, which are fixedly connected with the metal shielding layer 204 and fixedly installed on the embedded groove 201. The sealing groove 305 is embeddedly connected with the sealing ring 203. The sealing ring 203 is in communication with the inner part of the sealing air bag 103. The water meter body 101 is embeddedly installed on the embedded groove 201. The sealing cover 301 is attached to the water meter body 101. The two pull rods 303 are slidably connected with the two fixed blocks 104. The two movable buckles 105 are embeddedly connected with the two clamping grooves 304. The visible window 302 is embeddedly installed on the sealing cover 301. The two pull rods 303 are fixedly installed on the sealing cover 301.

[0029] The effect achieved by the whole embodiment 2 is that the two fixed blocks 104 and the two movable buckles 105 are movably connected on the outer wall of the water meter body 101. The sealing cover 301 is placed above the water meter body 101. The two pull rods 303 are pulled to be clamped in the inner part of the two fixed blocks 104. The two movable buckles 105 are clamped with the two clamping grooves 304 to be fixed. When the inner part of the water meter body 101 needs to be viewed and maintained, the two movable buckles 105 are taken away to facilitate viewing and processing.

[0030] Working Principle: The water meter adopts a split-type structure design, isolating the main body of the water meter 101 from the top component 3. The metering basis of the water meter 101 originates from a mechanical structure. When water flows through the water meter 101, the impact force of the water flow drives the impeller inside the water meter 101 to rotate. The rotational speed of the impeller is proportional to the water flow rate. Through a gear transmission mechanism, the rotational motion of the impeller is transmitted to the digit wheel, which is engraved with different numbers. Its rotation represents the accumulated water consumption, thus realizing the basic water consumption measurement function. The removable sealing cover 301 is generally made of high-strength plastic or metal and is installed on the water meter 101 through a snap-fit ​​connection. Opening the two movable buckles 105 allows the two pull rods 3 to be pulled out. Lifting the top of the 03 cover allows it to be removed. A special rubber sealing ring 203 is used for sealing. This sealing ring 203 has good elasticity and corrosion resistance, allowing it to tightly fit the connection surfaces of the two parts, preventing water and moisture from entering the electronic components and ensuring their normal operation. The valve control device in the water meter body 101 is crucial for sealing. Maintaining good sealing allows opening the sealing valve 102 and squeezing the sealing airbag 103 to inflate the sealing ring 203. After inflating, close the sealing valve 102. Multiple reinforcing ribs 205 maintain the stable support of the water meter body 101. A viewing window 302 on the top of the sealing cover 301 allows a view of the interior. The sealing cover 301 and the water meter body 101... A sealing ring 203 is provided on the contact surface. The sealing ring 203 is usually made of a material with good sealing performance. When the sealing valve 102 is opened, the sealing airbag 103 is squeezed to inflate the sealing ring 203. It is compressed when the sealing cover 301 is installed, thus forming a tight seal between the sealing cover 301 and the water meter body 101, preventing water and dust and other impurities from entering the interior of the water meter body 101. At the same time, multiple reinforcing ribs 205 are set inside to support it and maintain its stability. When it is necessary to perform maintenance, repair or battery replacement on the inside of the water meter body 101, the sealing cover 301 can be removed by pressing and sliding the buckle connection. During the removal process, the sealing ring 203 will disengage and will not cause any damage. The damage caused is to ensure that the sealing cover 301 can continue to function when it is reinstalled. During installation, simply align the sealing cover 301 with the corresponding position on the water meter body 101 and follow the reverse steps of removal to ensure that the sealing cover 301 is installed in place. Install two fixing blocks 104 on the outer wall of the water meter body 101 and connect them to two movable buckles 105. Place the sealing cover 301 on top of the water meter body 101 and pull the two pull rods 303 to lock it into the two fixing blocks 104. Lock the two movable buckles 105 and the two slots 304 to keep it fixed. When it is necessary to inspect and repair the inside of the water meter body 101, open the two movable buckles 105 and remove it for easy inspection and handling.

[0031] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
