Abstract

The utility model relates to an automatic washing filter comprising a base (4), a filter cylinder (5) and a filter core (6). The base is provided with a water inlet (1), a water outlet (2) and a clean water outlet (3). The water inlet (1) is configured as a tubular structure and forms an inclination angle toward the lateral along the horizontal direction. One end of the clean water outlet (3) is connected with a running water pipe and its another end is connected with a hollow area coaxially at one end of the filter core (6). The utility model adopts spiral-type water intake mode, thus the automatic washing can be realized without dismantling and stopping the operation.

Description

Automatic backwash filter

Affiliated technical field

The utility model relates to a kind of automatic backwash filter that needn't dismantle.

Background technology

Because the filter of generally selling on the market has only water inlet and pure water inlet, and substantially all adopt the cotton or filtering materials such as pottery, doughnut of PP, impurity such as particle in the water and harmful substance are stoped outside filtering bodies, promptly stay in the filter cavity and can't discharge, thereby generation secondary pollution, therefore filter in use for some time, must through taking apart clean or more renew cartridge could continue use, promptly bother expensive again.At present, known needn't the filter that can clean automatically out of service, need to use motor or motor and structure more complicated, original filter must be removed during use and reinstall even change the water route structure, increased use cost, be difficult for popularizing.

Summary of the invention

The purpose of this utility model is to provide a kind of and needn't dismantles, needn't be out of service, utilize other water in the life to clean automatically, and can be general, need not to change the automatic backwash filter of the basic structure of original filter again with the traditional filtering tube to filter.

Technical scheme

The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic backwash filter, comprise base, cartridge filter and filter core, and base is connected with screw thread with cartridge filter; Wherein base is provided with water inlet, delivery port and pure water inlet, water inlet, delivery port one end are connected with pipeline or tap with screw thread, the water inlet other end is a tubular structure, horizontal direction tilts laterally and upwards forms an inclination angle, and the end hollow area is coaxial is connected for pure water inlet and filter core one.

Beneficial effect

The beneficial effects of the utility model:

1, needn't dismantle also needn't be out of service for filter, can realize the purpose of flushing automatically, reduced secondary pollution.

2, adopt spiral water inlet, help the discharge of impurity in the water.

3, prolong filtering bodies service life and simple in structure, installation and maintenance is convenient, low cost of manufacture and saving water source.

4, only needing to change a filter base can be general with the traditional filtering tube, is easy to popularize.

The specific embodiment

As shown in Figure 3, automatic backwash filter mainly comprises base 4, cartridge filter 5 and filter core 6, and wherein cartridge filter 5 and filter core 6 are connected with screw thread with base 4 respectively.As Fig. 1, shown in Figure 2, base 4 is provided with water inlet 1, delivery port 2 and pure water inlet 3, wherein water inlet 1 is a tubular structure, one end is connected with pipeline or tap with screw thread, the angle that is inclined upwardly the other end tilts simultaneously laterally near cartridge filter 5 cavity inner walls, be that horizontal direction tilts laterally and upwards forms an inclination angle, pure water inlet 3 one ends are connected with running water pipe, coaxial being connected of hollow area of the other end and filter core 6 one ends, when water enters in the cartridge filter 5 from the water inlet 1 that the angle of inclination is arranged, water forms spiral water inlet under the effect of pressure, its impulse force makes the water that enters in the cartridge filter 5 rotate along the inwall of cartridge filter 5, make bulky grain in the water and impurity sedimentation rapidly and more concentrated, when opening delivery port 2, water is discharged by delivery port 2 under the effect of rotatory inertia and hydraulic pressure, takes away the impurity in the cartridge filter 5, and the water purification after the filtration flows out from pure water inlet 3.

Claims

1, a kind of automatic backwash filter comprises base (4), cartridge filter (5) and filter core (6), it is characterized in that: cartridge filter (5) is connected with screw thread with base (4) respectively with filter core (6).

2, automatic backwash filter according to claim 1 is characterized in that: the water inlet (1) that described base (4) is provided with is a tubular structure, and horizontal direction tilts laterally and upwards forms an inclination angle.

3, automatic backwash filter according to claim 1 is characterized in that: pure water inlet (3) one ends that described base (4) is provided with are connected with running water pipe, coaxial being connected of hollow area of the other end and filter core (6) one ends.
