There is fore filter and the cleaning device thereof of self-cleaning function
Technical field
The present invention relates to purifier field, particularly relate to a kind of fore filter with self-cleaning function.
Background technology
In the middle of existing Domestic water purifying industry, generally using maximum products in our daily life is exactly reverse osmosis water purifier and ultrafiltration water purifier, but water purification product has certain requirement to water source, as required, water source is municipal tap water, hydraulic demand is 0.1 to 0.4MPa, this is not any problem for city and flourishing small towns, county town, but, for the rural area that China is vast, the water quality in a lot of place is very poor, the even running water had does not have yet, be all underground well water, very muddy, they are only and need most water purification product.Because rural area water quality is poor, the water purifier that we commonly use is after installing and using, and filter core is stifled soon, will more renew cartridge, and namely filter core is very short for service life.Even installed the water purifier of fore filter additional, preposition filter core also can be blocked by impurity such as silts very soon, need often cleaning, and the cleaning of preposition filter core is difficult to oneself complete for most consumer, therefore common water purification product is not adapted at rural area practicality.
Summary of the invention
The present invention is directed to the shortcoming that water purifier of the prior art is not suitable for using in rural area, provide a kind of fore filter with self-cleaning function.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
There is the fore filter of self-cleaning function, comprise housing, the filter screen be installed in housing, also comprise cleaning device, the bristle that cleaning device comprises motor, rotating shaft and is fixed in rotating shaft, rotating shaft is stretched in filter screen, and driven by motor rotating shaft rotates, and bristle is with rotating shaft spin-cleaning filter screen inwall.
As preferably, cleaning device also comprises shaft coupling, and the motor shaft of motor is connected with rotating shaft by shaft coupling.
As preferably, housing bottom is provided with sewage draining exit, and sewage draining exit is communicated with its interior, opens sewage draining exit, and the water of its interior flows out from sewage draining exit.
As preferably, sewage draining exit is also connected with the first magnetic valve.Open the first magnetic valve, sewage is discharged from sewage draining exit.
As preferably, housing is provided with water inlet and delivery port, and water inlet is communicated with its interior, and it is peripheral that delivery port is communicated with filter screen, and delivery port is also connected with the second magnetic valve.
As preferably, housing comprises upper cover and main body, and main body is three-port structure, and the two ends, left and right of main body are respectively water inlet and delivery port, and sewage draining exit is positioned at lower body part, and lower end and the main body of upper cover are threaded connection.
As preferably, motor is positioned at upper cover inside, is provided with waterproof support chip between upper cover and main body, and the motor shaft of motor is through waterproof support chip.Waterproof support chip is a plastic sheet, is provided with sealing ring between plastic sheet sidewall and shell, and motor shaft is through this plastic sheet, and waterproof support chip plays the effect of support motor, can contact with motor by anti-sealing again simultaneously.
The cleaning device of fore filter, the bristle comprising motor, rotating shaft and be fixed in rotating shaft, driven by motor rotating shaft rotates.
As preferably, also comprise shaft coupling, the motor shaft of motor drives rotating shaft to rotate by shaft coupling.
The present invention compared with prior art has obvious advantage: the present invention utilizes cleaning device to clear up its interior; solve the problem of fore filter filter screen not easy cleaning thoroughly; reduce the clean and maintenance cost of filter itself; screen surface can not be blocked easily; protect water purifier filter core to greatest extent; extend the service life of water purifier filter core greatly, bring practical benefit to consumer.
