[Meter's Latest Patent] An Intelligent Water Meter

Content Description

The utility model relates to an intelligent water meter, belonging to the technical field of water meters.

Background of the invention

The smart IC card water meter is a new type of water meter that uses modern microelectronic technology, modern sensor technology, and smart IC card technology to measure water consumption and transmit water data and settlement transactions. The existing general smart IC water meter is mainly composed of a water meter. , Water meter box, LCD circuit board, liquid crystal circuit board installed on the water meter base meter, water meter box with IC card socket and equipped with LCD perspective window, water meter box cover on the LCD circuit board, IC card inserted through the IC card socket intelligent Inside the water meter box of the water meter, the liquid crystal screen can be observed through the liquid crystal see-through window of the water meter box. Since the IC card socket is easy to enter the foreign matter upwards, and because the water meter is generally installed in the kitchen, the bathroom has acid gas or other gas and is easily wet. In places, when the seal is not good, the humid gas can easily enter the water meter, causing damage to the battery and other components and corrosion of the circuit. This can easily cause malfunction or destruction of the control device. If the mechanical or circuit part fails, the mechanical and electrical components must be damaged. Need to be dismantled, difficult to handle, difficult to maintain. The existing water meter sets the IC card socket on the side, and there is no protection at the socket, which causes dust and foreign matter to enter the socket, resulting in poor contact.

Summary of the Invention

To solve the above problems, the technical problem to be solved by the utility model is to provide a smart water meter.

The intelligent water meter of the utility model comprises a lower box, a removable shaft, an upper cover, a liquid crystal display screen and an IC card slot; a dial perspective window is arranged on the lower box; the upper face of the lower box is vertically installed A detachable rotating shaft is mounted on the detachable rotating shaft, a liquid crystal display is mounted on the upper cover, and an IC card slot is disposed on the front side of the upper cover; it also includes a cleaning brush and dust a cleaning brush is installed on the left and right ends of the upper cover; both ends of the cleaning brush extend to the outside of the lower box; a dust-proof mechanism is installed at the front end of the IC card slot; The mechanism comprises a shell, an anti-dust rubber sheet, a dust cover, and a limiting rubber block; the front side of the shell is provided with an inclined surface inclined inwards, and a spring return shaft is installed on an upper end of the inclined surface, and the spring resets the shaft A dust cover is mounted on the housing, a slot is provided in the interior of the housing, dustproof rubber sheets are mounted on the upper and lower ends of the front side of the slot, and upper and lower ends of the slot are installed with limiting rubber blocks.

The figure shows the structure of the utility model

Further, the outer surface of the limiting rubber block 11 is provided with a cleaning cloth.

The working principle of the present embodiment is: in use, the whole installation is realized through the lower box 1 , and the electrical and mechanical separation type is adopted, which is convenient in electrical maintenance, and the electrical machinery is not easy to interfere with the electrical, the maintenance rate is reduced, and the machine needs to be viewed. In the watch, the upper cover 3 is rotated by the rotating shaft, and the cleaning brush realizes the cleaning of dust on the upper surface of the lower box when rotating, and at the same time when the IC card is plugged in, the dust cover 10 is lifted and then the housing 8 is inserted. In the slot, during the insertion, the dustproof rubber sheet 9 scrapes the dust on the IC card, and the foreign matter and dust on the IC chip are cleaned by the cleaning cloth, and the limiting rubber block 11 achieves a limit, so that the card body It is not easy to loosen, and the inclined surface of the housing makes it difficult for dust to stay on the dust cover to achieve the effect of dust prevention. The dust cover is of a sealed type and the gas does not easily enter the slot.

Preferably, the inner sidewall of the dust cover is provided with a groove, and a sealing ring is mounted on an outer side of the dust cover. The outer surface of the limiting rubber block is provided with a cleaning cloth.

Compared with the prior art, the beneficial effects of the utility model are: it is easy to realize dust prevention and dust removal, prolongs the service life, and is easy to operate, high in efficiency, and convenient for quick maintenance.
