Description
Technical field
This utility model belongs to life appliance field, and in particular to a kind of preposition water of the back flush type for Drinking Water
Filter.
Background technology
Fore filter filter screen adopts sintering filter screen, because filter screen is the element of life-time service, in filter pipe impurity
During, it is a very important technology barriers that the impurity on filter screen is rinsed.At present, the flushing that most producers adopt
Mode has two kinds：The first is positive backwashing manner（Fig. 1 and Fig. 2）, i.e., as the direction of product filtration, flow process；It is for second
Opposite direction backwashing manner（Fig. 3 and Fig. 4）, rinse together from its interior and outside.
All it is the drawbacks of rinsing impurity, such backwashing manner along the former direction for filtering water route using above two mode
Have following：
1. flushing direction is identical with filtering direction, and flush efficiency is not high, not thoroughly.Reason：Due to the mistake of water route protector
Filter mode is that the granule foreign in tap water is isolated by the interception of filter screen, therefore most granule foreign is all attached to
Above filter screen, when rinsing direction as filtering direction, these granule foreigns on filter screen are protected by the space of filter screen, nothing
Method front is rinsed, so punching is not washed clean；
2. what filter screen was rinsed is not comprehensively thorough enough.Reason：The surrounding of circular filter screen can be attached during product use
Many impurity, when rinsing, because water inlet is on one side of filter screen, it is impossible to clean to whole filter screens completely.
The content of the invention
For the deficiencies in the prior art, the purpose of this utility model is directed to the preposition water filtration of back flush type
Device, is processed come water (flow) direction using self structure change with the automatically cleaning for realizing filter screen, for solving backwash water route and filtering
When water route is consistent, carry out that filter screen flush efficiency in backwash process is low and filter screen rinses halfway problem.
For achieving the above object, this utility model is using such as purgation technical scheme：
The preposition water filter of back flush type, lid including the outlet with water inlet and is detachably connected ground with lid
Cylinder, defines filter cavity in the cylinder, filter screen is arranged in cylinder and the filter cavity is separated into into interior filter chamber
Body and outer filter cavity, the water inlet is connected with the interior filter cavity, and the outlet is connected with outer filter cavity；It is described
The bottom of cylinder is provided with discharge outlet, which is provided with drain valve；The discharge outlet is connected with interior filter cavity；It is characterized in that：Institute
State and the current conversion equipment that current can be switched in normal filtering operation and recoil operation is provided with lid；The current conversion
Device includes：Intercept the cut-off block that water inlet is connected with outlet, piston plug, the driving piston that interior filter cavity can be blocked
The top knob that plug is shifted up and down, the cut-off block is provided with circulation passage, and described circulation passage one end connects with outlet,
The other end of the circulation passage is located at the upper pan position of piston plug so that piston plug blocks stream when being located at upper pan position
Circulation passage, piston plug blocks interior filter cavity when being located at lower pan position.
Further, the top knob is located at lid upper end, and is connected with piston plug by screw rod；In the lid
Be provided with the female thread cap matched with screw rod, one end of the screw rod is connected with female thread cap, the screw rod it is another
One end is fixedly connected with piston plug.
Further, the bottom of the filter cavity is provided with filter screen mounting seat, and the filter screen is arranged on the filter screen and installs
On seat, be provided with drain outlet in the filter screen mounting seat, the drain outlet respectively with interior filter cavity and discharge outlet
Connection.
Further, the lid is to be threadedly coupled with cylinder.
Because above-mentioned technical proposal is used, this utility model has compared with prior art following advantages：
The preposition water filter of back flush type that this utility model is provided, by the displacement up and down of piston plug stream is blocked respectively
Circulation passage and interior filter cavity are controlling the water (flow) direction of water inlet inflow so that filter screen is lighter in cleaning, and power is bigger,
Direction is more reasonable.By the regulation to above-mentioned current, can realize just rinsing and two kinds of cleaning ways of backwash, rinse improving
While sales volume, washing time is shortened, and then saved wash water.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to this utility model：
Embodiment：
With reference to shown in Fig. 5 and Fig. 6：The preposition water filter of back flush type, including the outlet 1-2's with water inlet 1-1
Lid 1 and with lid 1 be detachably connected ground cylinder 2（In the present embodiment lid is to be threadedly coupled with cylinder, it would however also be possible to employ its
His connected mode, such as snaps connection）, defining filter cavity in the cylinder 2, filter screen 3 is arranged in cylinder 2 and by the mistake
Filter chamber body is separated into interior filter cavity 4 and outer filter cavity 5, and the water inlet 1-1 is connected with the interior filter cavity 4, described
Outlet 1-2 is connected with outer filter cavity 5；The bottom of the cylinder 2 is provided with discharge outlet 7, which is provided with drain valve 8；The row
The mouth of a river 7 connects with interior filter cavity 4.In order to improve the stability of the placement of filter screen 3, the bottom of the filter cavity is provided with filter screen
