Description

Technical Field

[0002] Smart water meters utilize modern microelectronics, sensing technology, and smart IC card technology to measure water consumption, transmit water usage data, and settle transactions. This represents a significant improvement over traditional water meters, which typically only record flow and display water usage using a mechanical pointer. In addition to recording and electronically displaying water consumption, smart water meters can also control water consumption according to agreed-upon regulations, automatically calculate water charges based on tiered pricing, and store water usage data.

[0003] Prior art, such as Chinese Patent No. CN101886941B, discloses a "smart water meter" comprising a lower case, an upper cover, an IC card slot, and a liquid crystal circuit board.

This smart water meter allows the upper cover to rotate horizontally parallel to the upper surface of the lower case, minimizing space and facilitating ease of use, particularly for viewing data and inserting cards.

[0036] The working principle of this embodiment is as follows: through the arrangement of the electric telescopic rod 23 and the chip mounting structure 22, when the communication mode needs to be changed during use, the transmission motor 27 can be turned on to drive the second gear 28 to rotate, and the second gear 28 drives the first gear 26 to rotate, thereby driving the rotating disk 21 to rotate, and the mounting block 221 for mounting the communication chip is moved to the top of the outer sleeve 210, and the chip mounting structure 22 is pushed to move by the electric telescopic rod 23, so that the buckle wire 215 is inserted into the third channel 2213, so that the end of the buckle wire 215 is locked.

Different communication modes can be changed in different application scenarios for easy use, and each communication chip is installed in the installation inner groove 224, and connected to the connection card block 211 through the electrical contact bottom groove 226. This can prevent the inconvenience of replacement and installation between each chip due to different connection methods, thereby increasing adaptability;

[0037] At the same time, according to Figure 6 - Figure 8 As shown, a sliding inner cavity 216 is provided at the upper end of the outer sleeve 210, and a sliding block 213 is connected to the sliding inner cavity 216. An O-shaped spring piece 217 is fixedly connected between the bottom of the sliding block 213 and the sliding inner cavity 216. The end of the sliding block 213 is designed in an arc shape. The sliding block 213 is located on both sides of the rotating connecting disk 214. Through the setting of the sliding block 213, when in use, the elasticity of the sliding inner cavity 216 can be used to extend the sliding block 213, thereby restricting the rotating connecting disk 214, so that the snap wire 215 is always in a vertical state, so that each time the installation block 221 is connected to the outer sleeve 210, the snap wire 215 can be ensured to enter the third channel 2213, thereby ensuring the connection between the installation block 221 and the outer sleeve 210.

[0038] At the same time, according to Figure 1 - Figure 2 As shown, an observation dial 18 is provided above the upper portion of the installation front panel 12, and a display screen 19 is provided below the middle portion of the installation front panel 12. The input end of the display screen 19 is electrically connected to the output end of the circuit board 110. The observation dial 18 is used to mechanically display the water pressure, and the display screen 19 is used to display the detected water flow data.

[0039] At the same time, according to Figure 1 - Figure 2As shown, a protective plate No. 13 is slidably connected to the upper middle part of the front panel 12, and a protective plate No. 2 is slidably connected to the lower middle part of the front panel 12. A transparent glass plate 14 is fixedly connected to the interior of the protective plate No. 2 15 and the protective plate No. 1 13. An upper end of one side of the protective plate No. 1 13 and a lower end of one side of the protective plate No. 2 15 are fixedly connected to an end buckle strip 16. A connection port 17 is fixedly connected to one side of the upper and lower ends of the water meter rear shell 11. The provision of the protective plate No. 1 13 and the protective plate No. 2 15 is used to protect the observation dial 18 and the display screen 19 from external collisions and damage. The provision of the transparent glass plate 14 facilitates observation of the data on the observation dial 18 and the display screen 19, thereby facilitating use.

[0040] At the same time, according to Figure 9 - Figure 11 As shown, a magnetic retaining ring 218 is fixedly connected to the inner outer edge of the rotating disk 21, and an outer slot 222 is provided on the outer surface of the mounting block 221. A magnetic ring 223 is fixedly connected to the inner part of the outer slot 222. Through the arrangement of the magnetic ring 223 and the magnetic retaining ring 218, when the chip mounting structure 22 is taken out and reset, the chip mounting structure 22 can be connected to the rotating disk 21 through the adsorption of the magnetic ring 223 and the magnetic retaining ring 218, and then the rotating disk 21 is rotated to replace the chip mounting structure 22 for installation.

[0041] At the same time, according to Figure 10 - Figure 11 As shown, an end card slot 227 is provided at the outer edge of the upper end of the inner groove 224, and a card base 228 is fixed inside the end card slot 227, and a heat sink 229 is fixed on the upper end of the card base 228. Through the arrangement of the card base 228 and the heat sink 229, the chip installed in the inner groove 224 can be protected to prevent the entry of dust and other impurities, and at the same time, the heat generated by the chip during use can be dissipated to increase the use time.

[0042] At the same time, according to Figure 4 and Figure 10 As shown, the upper end of the heat sink 229 is fixedly connected to a rubber protective pad 2210, and one end of the connecting end plate 25 is fixedly connected to a protective rubber pad 24. Through the arrangement of the protective rubber pad 24 and the rubber protective pad 2210, when the electric telescopic rod 23 is used to squeeze the chip mounting structure 22 and the chip mounting structure 22 is connected to the outer sleeve 210, the heat sink 229 can be protected to prevent the heat sink 229 from being squeezed and bent.

[0043] At the same time, according to Figure 3 - Figure 6As shown, the two sides of the rotating connecting disk 214 are designed to be flat, and the output end of the mounting block 221 is bidirectionally electrically connected to the input end of the circuit board 110, and the output end of the chip electrical interface 225 is bidirectionally electrically connected to the input end of the electrical bottom groove 226. The flat design on both sides of the rotating connecting disk 214 is used to cooperate with the sliding stopper 213, and the sliding stopper 213 is used to limit the rotating connecting disk 214.

[0044] Working principle: various communication chips are installed into the installation inner groove 224, and the connection end of the communication chip is connected to the chip electrical interface 225. When in use, the connection port 17 is connected, and the water meter back shell 11 is energized. Then, when the communication chip needs to be replaced, the transmission motor 27 is turned on to drive the No. 2 gear 28 to rotate, thereby driving the No. 1 gear 26 to rotate, and the appropriate communication chip in the installation block 221 is moved to the top of the outer sleeve 210. Then the electric telescopic rod 23 is controlled to extend, and the protective rubber pad 24 is driven by the connecting end plate 25 to squeeze the rubber protective pad 2210, so that the installation block 221 is squeezed out from the rotating disk 21, so that the snap wire 215 is inserted into the snap bottom groove 219 and snapped into the No. 3 channel 2213. Then the snap wire 215 is snapped into the No. 2 channel 2212, and the installation block 221 is limited. At the same time, the lower end of the installation block 221 is snapped into the inside of the outer sleeve 210. The connecting card block 211 is connected to the electrical contact bottom groove 226, and the communication chip is electrically connected and started. When in use, the card bottom plate 228 and the heat sink 229 dissipate the heat on the chip. When replacing the chip mounting structure 22, the electric telescopic rod 23 drives the connecting end plate 25 to move, pressing the chip mounting structure 22, cooperating with the magnetic force of the magnetic ring 223 and the magnetic clamping ring 218, and engaging with the fourth channel 2214, and sliding out of the first channel 2211. The magnetic force of the magnetic ring 223 and the magnetic clamping ring 218 adsorbs and fixes the mounting card block 221 on the rotating disk 21, and then the transmission motor 27 rotates, driving the rotating disk 21 to rotate again. In the same way, the communication chip can be replaced. The elasticity of the O-shaped spring piece 217 will squeeze the sliding block 213 to limit the rotating connecting disk 214, so that the snap wire 215 is in a vertical state, thereby ensuring that the snap wire 215 can be snapped with the third channel 2213.

[0045] In this technical solution, the transmission motor 27 and the electric telescopic rod 23 are both existing technologies and will not be elaborated on here.
