[instrument patent] originality without limitation, instrument big invention. Today we introduce a national invention patent - an intelligent water meter. The patent was applied by Zhengzhou Student Electronic Technology Co., Ltd., and was authorized to announce in July 18, 2017.
Content description
The utility model relates to an intelligent water meter, which belongs to the technical field of water meters.
Invention background
The intelligent IC card water meter is a new type water meter by using modern microelectronic technology, modern sensor technology, smart card technology was used for the measurement of water consumption and water use data transfer and settlement transactions, the existing intelligent IC meter by meter base meter, meter box, LCD circuit board, LCD circuit board is installed in the water base table. The meter box is provided with an IC card socket and a liquid crystal window, water meter box cover on the LCD circuit board, water meter box IC card IC card socket is inserted into the intelligent water meter, meter box window perspective through the LCD, LCD screen can be observed, because the IC card socket upward for easy access to foreign bodies, and because the meter installed in the the kitchen, bathrooms and other acidic gas or other gases and easy to damp places, gas seal is not good when wet can easily enter the water, batteries and other components damaged Corrosion circuit is easy to cause the malfunction or destruction of the control device. If the mechanical or circuit part fails, the mechanical and electrical components need to be disassembled, and the loading and unloading are difficult and difficult to maintain. The existing water meter is provided with an IC card socket arranged at the side, and the socket is not protected, which leads to dust and foreign matters entering the socket and causes bad contact.
summary of the invention
In order to solve the above problems, the technical problem to be solved by the utility model is to provide an intelligent water meter.
An intelligent water meter of the utility model, it contains a lower box and a removable cover, a rotating shaft, a liquid crystal display, IC card slot; the lower box is provided with a dial viewing window, the upper surface of the lower box installed vertically with a detachable shaft, the detachable shaft is installed on the upper cover, the the upper cover is installed on the LCD screen, the upper cover is arranged in front of the IC card slot; it also includes a cleaning brush and a dustproof mechanism; the upper cover of the left and right ends are arranged at both ends of the cleaning brush, cleaning brush to extend outside box, the front end of the IC card slot is installed on the dust the dustproof mechanism; mechanism comprises a shell, a dust dust cover, rubber sheet, rubber block limit; before the lateral surface of the shell is provided with inwards inclined surface, the upper end is provided with a spring reset inclined shaft, the spring return A dust cover is arranged on the bit shaft; the inner part of the shell is provided with a slot; the upper and the lower ends of the slot are provided with dust-proof rubber sheets; the upper and the lower ends of the middle hole are provided with a finite rubber block.
The utility model is a schematic diagram of the utility model
Further, the outer surface of the spacing rubber block 11 is provided with a cleaning cloth.
The working principle of the embodiment is: when in use, the lower box 1 to achieve the overall installation of the electrical and mechanical separation type, convenient in electrical, mechanical and electrical interference is not easy, reduce the maintenance rate, you need to look at the mechanical table, will cover 3 on the rotating shaft to rotate. When rotating, the cleaning brush to achieve dust under the surface of the box on the clean, at the same time in the IC card is inserted, the dustproof cover 10 lift, then inserted in the shell 8 slot, plug, dustproof rubber sheet 9 of the dust scraping through the IC card, foreign matters and dust on the IC chip through the cleaning cloth for cleaning. At the same time limit 11 rubber block limit, the card is not easy to loose, the slope makes the dust is not easy to stay in the dust cover, dustproof effect, and the dust cover is sealed, the gas is not easy to enter the slot.
As a preferred, the inner wall of the dust cover is provided with a groove, and the outer side of the dust cover is provided with a sealing ring. The outer surface of the limiting rubber block is provided with a cleaning cloth.
Compared with the prior art, the utility model has the advantages of easy to implement: dust and dust, prolong the service life, and convenient operation, high efficiency, convenient maintenance.
