The utility model solves its technical problem and is achieved through the following technical solutions：
A kind of Novel down-hole controller for water meter, including housing, circuit board, trigger switch, trigger switch coil, display screen and
Cable, housing includes back box and Shang Gai, and circuit board, trigger switch, trigger switch coil are installed in housing, circuit board connecting line
Cable, upper lid installs display screen, trigger switch, circuit board, display screen be electrical connection it is characterised in that：Described back box inner surface
It is formed with capsul under circuit board, circuit board is embedded in capsul under this circuit board, and sealing peace on capsul under this circuit board
Device, circuit board closure；It is formed with a switching circuit board draw-in groove in the bottom of described back box inner surface, in this switching circuit board draw-in groove
Interior setting-in switching circuit board, described cable is divided into inner lead and outside lead, and one end of inner lead connects circuit board, separately
One end connects to keyset, and one end of outside lead connects keyset, and the other end is drawn and is connected with external equipment.
And, adopt silica gel sealing between capsul and circuit board closure under described circuit board, in switching circuit board
Silica gel sealing is carried out on draw-in groove.
And, adopt silica gel sealing between the described back box of controller and upper lid.
Advantage of the present utility model and having the beneficial effect that：
1st, this Novel down-hole controller for water meter, is internally provided with circuit board capsul control shell, circuit board seals
Mounting circuit boards in shell, all carry out protective treatment to circuit board, capsul and controller housing, form the waterproof construction of multilayer；
Due to forming insulating space between the circuit board capsul of internal layer and shell, internal layer containment vessel is not steeped in water, is not contacted with water,
Do not allow fragile, seepage will not occur, thus can effectively prevent the steam in the external world from penetrating into circuit board, thus good guarantee
The moistureproof and waterproof effect of internal circuit board.
2nd, this Novel down-hole controller for water meter, inside the shell is provided with keyset, and one end of this keyset connects outside lead,
The other end connects inner lead, and inner lead connects to circuit board.Keyset be located inside the shell, be in dry type environment it is not easy to
Because of soaked damage, adopt encapsulating to encapsulate, liquid does not penetrate into keyset simultaneously, even if External cable crust is damaged, liquid
Being blocked at keyset, will not being sucked at circuit board, thus playing the waterproofing protection function to circuit board.
3rd, the utility model scientific structure design rationally, forms air exclusion environment in controller housing, effectively prevents
The entrance of environmental liquids, realizes effective water-proof function to original papers such as circuit boards.
