Abstract

The utility model provides a novel household water purifier. The utility model is characterized in that a backflushing sewage draining exit and a replaceable filter sleeve which can be cleaned are additionally arranged between a ceramic filter barrel and a water filling barrel, effectively preventing from the pollution by the aggregation of objects filtered out and preventing ceramic micropores from being clogged. The utility model has the advantages that the quality of the purified water and the efficiency for purifying water can be largely enhanced, and the service life of the whole product can be prolonged.

Description

The novel household water purifier

The utility model belongs to a kind of tap water filtering and purifying.

Process of industrialization is more and more serious to contaminated water source.Even treated tap water, because the pipeline of long distance transmits and the limitation of processing mode, still contain objectionable impuritiess such as a large amount of dissolved organic matters, heavy metal ion, bacterium, virus in the water, even seriously surpass the national standard of tap water, and be not just can avoid its evil by boiling, this has become one of important factor of bringing out multiple disease threat human health.Thereby all paid much attention to development in recent years both at home and abroad and drink the design of water purifying means, particularly domestic type and make rapid progress.The design of existing household water filter is made up of an injecting cylinder and the filtration unit that is arranged in the injecting cylinder basically, along with updating, the filtration unit of popularizing the domestic type water purifier is made up of two portions at present, first part is the outer filter ruffle that micropore ceramics or other type poromerics are formed, the filter core that second section is made up of gac.Whole filtration unit adds that being located at the injecting cylinder capping of taking water nozzle on the injecting cylinder out of is sealed to one, and itself has water-in injecting cylinder.Water enters injecting cylinder from water-in, and soluble solids in ceramic filter cylinder just filters to remove some water is done through active carbon filter core and selected absorption and form to purify waste water and flow out from faucet.Mainly there is following problem in such device, and promptly along with first filter forms the excessive thing that leaches between ceramic filter cylinder and injecting cylinder, these accumulation that leach thing cause the excessive breeding of bacterium and the obstruction of filter cylinder micropore, and this is a present water purifier shortcoming anxious to be overcome.

The purpose of this utility model promptly is to provide one can eliminate and leach the new texture design that thing gathers pollution, not only can guarantee the efficient and quality of purifying waste water and the work-ing life that can prevent the micropore filter material.

Crucial design of the present utility model is to set up a recoil mudhole in the bottom of original injecting cylinder.After having used for some time, this hole is opened, can discharge simultaneously and with the spissated thing that leaches in the space of washing away automatically between ceramic filter cylinder and the injecting cylinder from the clear water that water-in enters, every like this certain hour of crossing, the recoil decontamination once just can be eliminated the threat that concentrates nuisance widely, also can avoid the too early obstruction of ceramic element micropore to lose efficacy.

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.

Fig. 1 is to be structural representation of the present utility model.

Wherein 1 represent injecting cylinder, 1A represents the water-in on the injecting cylinder, 1B representative recoil sewage draining exit, and 1C represents plug, and 1D represents packing ring.2 is active carbon filter core, and 3 is ceramic filter cylinder, and 3A is the filter cylinder cover, and 4 is the injecting cylinder capping, and 4A is a faucet, and 5 and 6 is the caulking gum packing ring, and 7 is the water purifier base.

As can be seen from the figure, recoil mudhole (1B) is arranged on the bottommost centre of injecting cylinder (1).Stayed thing just to be collected at by consolidating of just being leached of ceramic filter cylinder (3) and particularly be deposited on the bottom in the injecting cylinder.When opening plug (1C), can be easy to and to rinse well between ceramic filter cylinder (3) and the injecting cylinder (1), and dirt is very convenient from the discharge of recoil sewage draining exit from the recoil of water-in (1A) introducing clear water.Like this,, recoiled and tightened plug (1C) again, can normally use as long as the recoil of every use for some time once.

Another design of the present utility model is to add a filter cylinder cover (3A) in ceramic filter cylinder (3) outside.This filter cylinder cover (3A) can be one the 400 above nylon wire of order, also can be the outside that directly is sleeved on ceramic filter cylinder (3) by the soft cover that is equivalent to 300-400 order net that the multi-layer fiber fabric is made.Impurity can hinder on filter ruffle (3A) in the water about 0.3 micron more like this, whenever, can take off that filter ruffle (3A) cleans or change through one period long period, can effectively prevent the obstruction of ceramic filter cylinder (3) micropore like this, big leap ahead drainage efficient and prolong water purifier work-ing life.

Recoil mudhole (1B) is located a plug of fit on (1C) and seal washer (1D), loads onto during application, pulls down during recoil.Can locate to load onto a switch at recoil mudhole (1B) for convenient, can make use easier like this.

According to the water purifier that above structure is made, carry out blowdown and anti-obstruction processing during use very easily, thereby its long-time service efficiency can be greatly improved than old product, life-span also prolongs 1 times, and whole cost there is no remarkable increase, thereby, be worthy of further application.

Claims

1, a kind of novel household water purifier, form by injecting cylinder (1), the injecting cylinder capping (4) that is arranged on active carbon filter core (2), the ceramic filter cylinder (3) in the injecting cylinder (1) and takes water nozzle (4A) out of, the water-in (1A) of water Automatic water-filling tube (1) enters, handle the back through ceramic filter cylinder (4) and active carbon filter core (3) and flow out, it is characterized in that being provided with the mudhole (1B) that recoils in the bottom of injecting cylinder (1) from faucet (4A).

2, according to the said water purifier of claim 1, it is characterized in that having added on the ceramic filter cylinder (3) a filter cylinder cover (3A), the position is between ceramic filter cylinder (3) and injecting cylinder (1).

3,, it is characterized in that filter cylinder cover (3A) is one the 400 above nylon wire of order, is fixed on the outside of ceramic filter cylinder (3) according to the said water purifier of claim 2.

4,, it is characterized in that filter cylinder cover (3A) also can be that the multi-layer fiber fabric is made the outside that directly is sleeved on ceramic filter cylinder (3) according to the said water purifier of claim 2.
