【Instrument Patent】Creativity has no limit, instrument invention. Today I would like to introduce you to a national invention authorized patent - a smart water meter. The patent was applied for by Zhengzhou Shengbao Electronic Technology Co., Ltd. and was granted an authorization announcement on July 18, 2017.

Content description

The utility model relates to a smart water meter, which belongs to the field of water meter technology.

Background of the invention

The existing general intelligent IC water meter is mainly composed of water meter base meter, water meter box, LCD circuit board, LCD circuit board is installed on the water meter base meter, the water meter box is opened with an IC card socket and equipped with an LCD perspective window, the water meter box is covered on the LCD circuit board, and the IC card is inserted into the water meter box of the smart water meter through the IC card socket. Through the LCD perspective window of the water meter box, it can be observed that the LCD screen is easy to enter the foreign body because the IC card socket is facing upwards, and because the water meter is generally installed in the kitchen, bathroom and other places with acid gas or other gases and easy to get damp, the humid gas will easily enter the water meter when the sealing is not good, so that the battery and other components are damaged, corroded the circuit, and easy to cause the control device to fail or be damaged. The existing water meter has the IC card socket on the side, and the socket is not protected, resulting in dust and foreign objects entering the socket, resulting in poor contact.

Invention content

In response to the above problems, the technical problem to be solved by the present utility model is to provide a smart water meter.

A kind of intelligent water meter of the utility model, which comprises a lower box, a detachable hinge, an upper cover, an LCD display, and an IC card slot; the lower box is provided with a dial perspective window, the upper surface of the lower box is vertically mounted with a detachable hinge shaft, the detachable hinge shaft is equipped with an upper cover, the upper cover is equipped with an LCD display, and the front side of the upper cover is provided with an IC card slot; It also contains a cleaning brush, dust protection mechanism; the left and right ends of the upper cover are equipped with cleaning brushes, the two ends of the cleaning brush extend to the outside of the lower box, and the front end of the IC card slot is equipped with a dust-proof mechanism; the dust-proof mechanism comprises a shell, a dust-proof rubber sheet, a dust-proof cover, and a limiting rubber block; The front side of the shell is provided with an inward inclined bevel, the upper end of the inclined surface is equipped with a spring return shaft, the spring return shaft is equipped with a dust-proof cover, the inside of the shell is provided with a groove hole, the upper and lower ends of the front side of the groove hole are equipped with dust-proof rubber sheets, and the upper and lower ends of the middle of the groove hole are equipped with limited-position rubber blocks.

The figure shows the structural diagram of the present utility model

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

The working principle of this specific embodiment is: when in use, through the lower box 1 to achieve the overall installation, the electrical and mechanical separation type, which is convenient in electrical maintenance, and the machinery is not easy to interfere with the electricity, reduce the maintenance rate, when you need to check the mechanical meter, the upper cover 3 relies on the shaft to rotate, when turning, the cleaning brush realizes the cleaning of the dust on the upper surface of the lower box, and at the same time when the IC card is plugged in, the dust cover 10 is lifted, and then plugged into the slot hole of the shell 8, when plugged, the dust-proof rubber sheet 9 scrapes off the dust on the IC card, The foreign matter and dust on the IC chip are cleaned by a cleaning cloth, and the limit rubber block 11 is realized, so that the stuck body is not easy to loosen, and the bevel of the shell makes it difficult for the dust to stay on the dust cover, so as to achieve the effect of dust prevention, and the dust cover is sealed, and the gas is not easy to enter the groove hole.

As a preference, the inner side wall of the dust cover is provided with a groove, and the outer side of the dust cover is equipped with a sealing ring. 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 convenient to realize dust prevention and cleaning, prolong the service life, and is easy to operate, high efficiency, and convenient for rapid maintenance.
