Description of the Invention The utility model relates to the technical field of water meter equipment, in particular to an intelligent water meter with an anti-fog and transparent window.
BACKGROUND OF THE INVENTION A smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption and transmit water data and settlement transactions. Among them, the pulse card meter and remote meter are still one of the mainstream smart water meters on the market. The basic working principle is to add a group of magnetic steel and reed tubes, or magnetic steel and Hall elements to a common water meter. The data acquisition sensor, while the water metering component is rotating, the magnet rotates synchronously, triggering the reed switch or Hall, and the output pulse is transmitted to the intelligent water meter module for electromechanical conversion to achieve the purpose of measuring the water consumption with the electronic module.
The common structure of the water meter consists of a base meter (a general water meter equipped with a sensor), an electronic module, a battery, a housing for mounting an electronic module and an electronic body, and a transparent window. Transparent windows are often welded to the shell using an ultrasonic welding process and cannot be removed. In daily use, the user can read the dial reading through the transparent window. At the same time, a certain distance is maintained between the transparent window and the sensor, which can avoid the interference of the external magnetic field to the sensor or the man-made magnetic attack. However, when using the water meter of the above structure, the user often feeds back a problem: since the space between the transparent window and the watch glass of the water meter is directly exposed to the atmosphere, the bottom of the transparent window often condenses water mist due to weather changes and the like. , affecting the user to read the water meter dial readings.
SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a smart water meter with an anti-fogging and transparent window, which can effectively prevent condensation at the bottom of the transparent window and achieve the purpose of preventing fogging.
In order to solve the above technical problem, the utility model provides an intelligent water meter with a transparent atomization-proof window, comprising a housing, a transparent window is arranged on the housing, and a lower surface of the window is provided with a watch glass. A sealing ring is provided between the window and the watch glass. 
The figure is a schematic diagram of the structure of a water meter with an anti-fog transparent window according to an embodiment of the present invention

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduced a national invention-issued patent - a smart water meter with anti-fogging and transparent windows. The patent was applied by Sanchuan Wisdom Technology Co., Ltd. and it was authorized on April 26, 2017. Further, the watch glass is mounted on a lower portion of the window through a mask, and the sealing ring is disposed in the cover and is disposed between the window and the watch glass. The seal ring includes a horizontal portion and a vertical portion, the vertical portion is connected in the cover, and the horizontal portion is installed between the window and the watch glass. A tamper ring is mounted between the housing and the window. The housing is provided with a mounting opening corresponding to the upper portion of the watch glass, the window is installed in the mounting opening, and the detachable ring is installed between the mounting opening and the window. . The mounting opening is provided with an internal thread, the window is provided with an external thread, and the window is installed in the mounting opening by a screw thread. The seal ring is an O-ring seal. The lower part of the watch glass is provided with the sensor The above technical solution of the utility model has the following beneficial effects: The smart water meter with an anti-fogging and transparent window of the present invention comprises a housing, a transparent window is arranged on the housing, and the lower part of the window corresponds to Table glass is provided, and a sealing ring is arranged between the window and the watch glass. The water meter uses a sealing ring to form a sealed space between the transparent window and the watch glass, effectively blocking the flow of air from the outside, so as to achieve the purpose of preventing fogging. In addition, considering that some water meter installation environments are rather harsh, they may be soaked in water for a short time. A tamper ring is added to the structure. The tamper ring can only be disassembled if damaged. If the seal fails, maintenance personnel can perform maintenance in time. It can also prevent ordinary users from disassembling and installing themselves; the smart meter is simple in structure, easy to use and manufactured, and easy to maintain and replace internal parts.
