Abstract
The utility model relates to a chargeable intelligent water meter and gas meter. The power supply adopts a rechargeable battery on whose case a charging seat is connected. A charging circuit connected with the rechargeable battery is arranged in the charging seat. A power supply connector of the charging circuit is arranged on the charging seat. The power supply connector can be either a power supply jack or a power plug connected with a piece of conductor. The charging seat can be arranged in the special cavity on the internal side of the case. An opening is arranged on the external wall of the cavity. A cover board which can be disassembled is arranged on the opening. The power supply interface is exposed on the opening. When the battery is out of electricity, users can insert the power cord to the power supply jack for charging. The power cord can be disconnected after charging. The utility model has the advantages of no need for replacing batteries. The normal use of water meters and gas meters for users and factories is ensured.
Description
Technical field
The utility model relates to a kind of rechargeable type intellectual water meter, gas meter.
Background technology
The interior usually dress disposable battery of existing intellectual water meter, ammeter after battery uses up, needs producer to send someone to open shell as power supply, replaces with new battery.Because producer makes house calls and needs the regular hour, before battery was not changed, the user can't normally use.
The utility model content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of rechargeable type intellectual water meter, gas meter, can charge again after the dead battery of this water meter, gas meter, and user oneself just can carry out charging operations, does not need producer to make house calls.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of rechargeable type intellectual water meter, gas meter, its power supply adopts rechargeable battery, be connected with a cradle on its shell, be provided with the charging circuit that is connected with described rechargeable battery in the described cradle, described cradle is provided with the mains connection of described charging circuit, described mains connection can be outlet usually, also can be the attaching plug that is connected with a section lead.
Because the utility model adopts rechargeable battery as power supply, and be provided with charging circuit and the outlet or the plug that are used to be connected external power supply, when dead battery, the user can ownly be connected to power supply on outlet or the plug and charge, pulling up plug after the charging gets final product, do not need producer to change battery to the doorstep, not only made things convenient for user and producer thus, and guaranteed the normal use of water meter, gas meter.
