For water source, but because therefore the cleanliness factor of running water and underground water not enough needs to install filter to ensure the cleaning of rinse water
Degree, it is to avoid silt etc. pollutes pcb plates, needs often to change the filter core of filter, by observing water using filter plant filter water
Stream or shutdown etc. check whether filter should change comparatively laborious.Therefore need to propose that one kind can observe filter element and make
With the device of situation.
Utility model content
In order to solve the above-mentioned technical problem the utility model proposes a kind of cleaning printed circuit board water filter, specific bag
Include：Housing, mounting cap, filter core and filter element replacing suggestion device；Include water inlet and delivery port, water inlet and sewage on housing
Source connection, the outlet of water filling port and clean water；Sewage enters filter core by water inlet, turns into clear from delivery port outflow
Clean water；Filter element replacing suggestion device includes pressure-detecting device, and pressure-detecting device includes the water of UNICOM's water inlet and delivery port
Pipe sets piston in water pipe, and the position of piston changes with the change of hydraulic pressure, and outside in water pipe sets elastic machine
Structure, the pressure that the hydraulic pressure being subject to for dummy piston is produced.
It is preferred that, on filter element replacing suggestion device, observation window is provided with, the position for observing piston.
It is preferred that, water pipe includes one end and the less one end of diameter for being relatively large in diameter, the one end being relatively large in diameter be connected into
On the mouth of a river, diameter small end is connected to delivery port, and piston is arranged on the less one end of diameter, in water pipe.
It is preferred that, internal piston comprising can magnetic absorption metal material.
It is preferred that, the elastic mechanism set outside water pipe includes compressible spring, and it is smaller that compressible spring is set in diameter
One end water pipe outside.
It is preferred that, be provided with the end of spring can magnetic metal material magnetic element, magnetic element has hollow
Borehole jack is located on the less one end of water pipe diameter.
It is preferred that, the pressure transmission that the piston is produced the hydraulic pressure being subject to by magnetic element is to flexible member to reach
Stress balance.
The advantageous effects that the utility model is obtained are that the hydraulic pressure of delivery port declines water inlet when filter core needs to change
Hydraulic pressure rise, piston is more than the hydraulic pressure of delivery port by the hydraulic pressure of water inlet, thus by pressure differential promotes the side to delivery port
To movement, due to internal piston comprising can magnetic metal material, therefore be arranged on the magnetic element of flexible member end by institute
Pressure transmission is stated to flexible member, when the elastic force of pressure and flexible member reaches balance piston just static stabilization in some position
Put.The pressure difference of the longer piston both sides of use time of filter core is bigger, then the position of piston is closer to delivery port, and user can pass through
The observation window being arranged on alarm set observes the service condition of filter core, decides whether to change.

Embodiment
With reference to the accompanying drawing of the utility model embodiment, the technical scheme being related to the utility model is carried out
Clear complete description, it is clear that the embodiment, is only used for explaining the technical solution of the utility model；Without limiting
Protection domain of the present utility model, protection domain of the present utility model should be so that the description of claim is defined.Art technology
Personnel are belonged within protection domain of the present utility model according to change of the present utility model or change.
Refer to the filter 1 shown in Fig. 1 includes water pump 11 and filter plant 12, and one end of water pump 11 is provided with three
Individual water source tube 13 is used for the rinse water for providing printed circuit board, is used to supply water to filter with three in the other end of water pump 11
Water pipe 14 connect.Three filters 2 arranged side by side are provided with the filter plant, for filtering the cleaning from water pump 11
Water, cleaning printed circuit board is directly used in from what the filter 12 flowed out for clean water.
It refer to the cleaning printed circuit board water filter 2 shown in Fig. 2, including housing 21, mounting cap 22, filter core 23 and filter
Core changes suggestion device 24；Housing and mounting cap are all known technologies, and are installed together in a manner well, again
Do not repeating.
Include water inlet 25 and delivery port 26 on housing, water inlet is connected with the source of sewage, delivery port 26 and cleaning
The outlet of water；Sewage enters filter core 23 by water inlet 25, and clean water is turned into from delivery port outflow；
The ft connection of water inlet 25 and filter element 23 in the present embodiment, delivery port 26 and filter element 23
Inside connection, can also be reversed and obtain same filter effect.
Above-mentioned filter core 23, which changes suggestion device 24, includes pressure-detecting device 241, and pressure-detecting device enters including UNICOM
The water pipe 242 of the mouth of a river 25 and delivery port 26 sets piston 243 in water pipe, and the position of piston changes with the change of hydraulic pressure
Become, outside in water pipe 242 sets elastic 245 mechanism, the pressure that the hydraulic pressure being subject to for dummy piston 243 is produced
Observation window 246 is provided with the replacing suggestion device of filter in the present embodiment, the position for observing piston
Put.
In the present embodiment, piston 243 is arranged in the water pipe of connection water inlet 25 and delivery port 26, is relatively large in diameter
One end is connected on water inlet 25, and diameter small end is connected to delivery port 26, and piston is arranged in the less water pipe of diameter, piston
243 inside are comprising that can be able to be common iron-based material by the metal material of magnetic absorption, the metal material, and metal material is embedded in institute
