Embodiment 1
[0024] see Figure 1-3 The present invention provides a technical solution: a smart water meter with moisture-proof and heating functions, including a water meter metering assembly 10, a water pipe connection assembly 20, and a moisture-proof heating assembly 30, and the water meter metering assembly 10 includes a water meter body 11, an IC card sensor Cassette 12, digital display 13 and mechanical display 14, the exterior of water meter body 11 has water meter shell 111, and water meter shell 111 is coated on the outer wall of water meter body 11, and is integral structure with water meter body 11, digital display 13 It is located on the upper surface of the water meter body 11, and the digital display 13 is electrically connected to the internal power supply. The IC card induction box 12 is hinged on the top of the water meter body 11. There is a mechanical display 14 under the IC card induction box 12. The display 14 is integrated with the water meter body 11. The water pip...
Embodiment 2
[0027] see figure 1 , the present invention provides a technical solution: different from Embodiment 1, the moisture-proof casing 31 can be made of plastic or metal, and the interior of the moisture-proof casing 31 can be filled with a desiccant other than activated carbon 32, when the moisture-proof casing 31 is a transparent plastic When the material is used, the inside of the moisture-proof shell 31 can be filled with color-changing silica gel or anhydrous copper sulfate with color reaction, and it can be decided whether to replace the inner filler according to the depth of the color.
[0028]Working principle: Connect the water inlet port 22 and the water outlet port 23 at both ends of the water valve body 21 to the water pipe respectively and seal them, so that the water meter body 11 faces upwards, connect the internal power supply, and insert the IC card into the IC card In the card slot 121, cover the IC card induction box 12 then. When using water, the water flow pass...
