The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Concrete structure as shown in Figure 1, water purifier of the present utility model comprises a upper filter 1 and a lower filter 3 with the combined type filter core, wherein upper filter 1 is arranged in the dimple of dividing plate 8 (this dividing plate can be the base plate of raw water box), be the siphon filtering type filter core that a former water flows through filtrate from bottom to top, have exhaust apparatus and disinfection box 5 in the filter core.Upper filter 1 can adopt buckle to be connected with dividing plate 8 or be threaded.With reference to shown in Figure 2, it mainly is to be made of upward filtration core body 13, upper and

lower web plate

14,11, filtrate 12, core pipe 19, spacer 17, diaphragm 16 and disinfection box 5 etc., wherein the top of upward filtration core body 13 have one with the return-air of its thread connection lid 18, and cover 18 and be provided with sealing ring 20 with filter body 13 connection places.One dimple is arranged at the top of lid, and there is an air-vent 15 centre.Diaphragm 16 places in the dimple and covers ventilative 15 holes.This diaphragm 16 1 is can limit former water to enter filter core from air-vent, the 2nd, can allow after the pneumatic jack that air-vent makes progress is away opened this diaphragm, enter raw water box.Spacer 17 is made ventilating structure, is placed on the diaphragm 16, is used for to diaphragm 16 spacingly, and diaphragm 16 can upwards not left behind the top because of being bullied.Filtrate 12 is located in the filter body 13, and

web plate

14,11 is located at the upper and lower of filtrate respectively up and down.Core pipe 19 is positioned in the middle of the filtrate, with core pipe 7 thread connection on the dividing plate 8, and with rubber seal 21 sealing.Wherein return-air lid 18 and diaphragm 16, spacer 17 constitute the exhaust structure of upper filters 1.

Disinfection box 5 is a box body independently, is the cylindricality box body that a centre that is assembled by inside and

outside tube

53,54 and upper and

lower cover

52,56 is the through hole shape, and disinfectant 55 is housed in box, and that upper and lower cover is all made is latticed, and silk screen 51 is set on grid.Silk screen 51 can be made flat screen net structure or oblique screen net structure as shown in Figure 4 and Figure 5.This disinfection box is placed in the return-air lid 18, is positioned at the filtered water delivery port place that filter body 13 and core pipe 19 interbody spacers constitute.It mainly is that the filtered water of coming out from last web plate 14 was carried out disinfection water before flowing into core pipe 19, to guarantee that the water bacteria index meets standard-required, simultaneously water again can be through the charcoal absorption of lower filter after sterilization, iodine after the sterilization is distinguished the flavor of effectively removed, and guarantees the water outlet mouthfeel.

Former water enters from the following web plate of upper filter bottom during use, after filtering through the particulate filter (as ion exchange resin) in the filter core, is come out to flow into the core pipe after the disinfection box sterilization by last web plate, flows into lower filter by the core pipe, realizes the primary filter of upper filter.And the air in the filtrate is directly discharged by air-vent owing to the effect of hydrocone type current.

The structure of lower filter 3 is the flow type filter element that falls that a bottom has water control valve 6 as shown in Figure 3, and it is contained in dividing plate 8 bottoms, mainly is made of lower filter body 31, filter core lid 34, web plate 37, filtrate 36, kink nut 40 and water control valve 6 etc.Wherein lower filter body 31 is a stepped cylindrical shell, and it is connected with pipe body 9 buckles of the lower partition, and seals 35 with O-ring seals.But lower filter body 31 also can adopt thread connection with dividing plate 8.Web plate 37 is arranged on the bottom of lower filter body, and filtrate 36 adopts active carbon, is contained in above the web plate 37.Filter core lid 34 covers above filtrate, and its lateral wall contacts cooperation with the filter body inwall, and cap is made latticed, and grid is provided with silk screen 32.There is tapered protrusion the centre of lid, and convex center has steam vent 33, can discharge for the air in the active carbon.

Fiber filtering 38 and water controlling board 62 are arranged in the filter body of web plate below by the kink nut 40 that connects with filter body, wherein there is a control water aperture 63 at the center of water controlling board 62, there is the gathering sill 66 that sealing gasket 65 and gasket base 64 can be set its underpart, and is provided with sealing ring 39 between the periphery of water controlling board 62 and filter body inwall.Through hole is arranged at the bottom of kink nut 40, can pass through for gasket base 64.After tightening for kink nut 40, also the fiber filtering in it 38 can be compressed simultaneously during assembling, can guarantee the sealing that filtering accuracy and water controlling board are circumferential.

Water control valve 6 mainly is made of float 61, water controlling board 62, sealing gasket 65 and gasket base 64, and sealing gasket 65 and gasket base 64 place in the gathering sill 66 of water controlling board, can move up and down along groove under the drive of float 61.The conical nose of sealing gasket 65 can be with the aperture shutoff over against control water aperture 63.The structure of float 61 as shown in Figure 6, its underpart is circular permeable orifice plate, interior ring bottom is a rib strip shaped, interior ring top and outer shroud are tubular, the top is circular.It is external that float 61 is enclosed within lower filter, places the place, centre position of float 61 base plates behind the through hole of bottom by kink nut 40 bottoms of sealing gasket 65 and gasket base 64.

This water control valve can be controlled the current filter process automatically according to the water level in the bucket, and its control water principle is as follows:

After former water purifies after filtration, enter bucket by water control valve, increase along with the water purification amount, the bucket water level rises, water in the bucket increases the buoyancy that float produces, cause float to rise, the drainage process is stopped the little hole plug of control water on the water controlling board and float drives conical gasket along with the rising of bucket water level.Discharge water when opening hot water or cold water's tap or discharge outlet, the bucket water level descends, water in the bucket descends to the buoyancy that float produces, and float begins to descend under the effect of self gravitation when buoyancy drops to certain phase, the recovery drainage process thereby the water control hole on the water controlling board is opened.So go round and begin again, control the current filter process automatically.
