The technical solution adopted by the utility model is: providing an intelligent water meter for an IC card, which includes a base watch whose both ends are connected with the inlet end and the outlet end of a water pipe, and the base watch is provided with a first housing containing a measuring component. The utility model is used for detecting the water flow in the base watch, which is characterized in that: a detachable second housing is arranged above the first housing, a viewing port is arranged on the second housing, and a double-layer transparent is embedded in the observation mouth. The glass is used for directly observing the degree of display value of the dial in the detection assembly. The double transparent glass forms a vacuum chamber with the inner wall of the second shell, and the vacuum chamber is filled with a filler that can change color when exposed to water.

Description of the Invention The utility model relates to the technical field of smart water meters, in particular to an intelligent water meter for IC cards.
Disclosure of the Invention IC smart water meter is a smart water meter developed on the basis of traditional water meters that can realize the opening and closing of water meters through prepayment. It has been widely promoted to dorms in universities, apartments, and enterprises and institutions. . However, the existing smart meter of the IC card generally follows the integral structure of the traditional water meter. Therefore, the chip and the circuit module in the IC card can only be replaced when the circuit module is damaged. Therefore, the cost is high.
BACKGROUND OF THE INVENTION The technical problem to be solved by the present invention is to provide an intelligent water meter for an IC card, which is easy to maintain, and does not need to be scrapped when the parts of the water meter are damaged, thereby saving costs. 
The figure is a schematic diagram of the structure of the smart meter of the IC card of the utility model
The vacuum chamber incorporates a luminous body for illuminating the upper value of the dial in a dark external environment. The luminous body is a ring structure, and an annular luminous body is attached to the inner wall of the vacuum chamber and fixed. A magnetic body is built in the first shell, and a layer of friction is wrapped around the outer magnetic layer. The first housing is provided with a containing groove facing upward for placing the magnetic body. After adopting the above structure, the intelligent water meter of the IC card of the present invention has the following advantages compared with the prior art: First, when the base sheet is damaged or needs to be replaced after reaching the service age, the electronic components in the second housing can be disassembled and used again. Secondly, when some of the electronic components in the second housing are damaged, they can be used directly after applying the calibration to the original set values, thereby reducing the maintenance cost of the smart water meter.
