Abstract

A household water purifier with a nesting type filter element is mainly formed according to the following method: a filter tube with the outside diameter smaller than the inside diameter of the filter element and the length less than the length of the filter element is arranged in the filter element of an existing filter bottle. Different filter materials and isolating layers separating the filter materials are arranged in the filter tube; and the upper part of the filter tube is inserted in and connected with a location ring. The utility model improves the unbalance state of the filtration of a lateral surface of the filter element and makes full use of the filter surface of the filter element; the filter tube increases the filter route of water by a plurality of times so that the purification effect is remarkable and serially connected filters are reduced, therefore the cost is reduced and the size is reduced; the filtration by adopting the filter materials not only purifies the water but also can supplement ingredients good for human body so as to obtain high-energy direct-drinking water; and the space of the existing filter element is fully utilized so that each part is fully used.

Description

A kind of household water filter of sleeve type filter core

Technical field the utility model relates to a kind of purifier.

The present people of background technology use more household water filter to be made up of single and a plurality of filtering flasks that are cascaded.This filtering flask is formed by cup-shaped bottle and loam cake, and the following locating ring and the concentric with it protruding lower sealing ring of projection established at middle part, the bottle end.Be provided with loam cake with its flexible connection in the upper shed of bottle, the one sidewall is provided with the inlet opening, and the middle part sets out the water hole, and it leads to the loam cake opposite side.Loam cake middle part apopore is established locating ring on the evagination that is connected as a single entity with it, also is provided with the evagination upper sealing ring concentric with last locating ring in this loam cake.Tubular cellucotton or active carbon filter core upper end perforate are enclosed within outside the locating ring, and the upper surface contacts with upper sealing ring; The lower end perforate is enclosed within down outside the locating ring, and the lower surface contacts with lower sealing ring.Its weak point is: 1, according to principle of hydrodynamics, water is to select the little place of resistance to walk, so passes through from the filter core first half more than the current, because of filter core the latter half resistance is big, seldom has current to pass through, and so just causes the filtering surface of filter core to use unbalanced.2, because effective filter run of water only is the thickness of filter core, stroke is shorter, so filter effect is limited.

The summary of the invention the purpose of this utility model is to provide a kind of can make full use of the filter element filtering face, can increase considerably the household water filter of the sleeve type filter core of filter run again.

The utility model mainly is a chimney filter of setting up dress filtrate in existing household water filter filter core, and itself and filter core are formed the sleeve type filter core.Above-mentioned chimney filter is an external diameter less than filter core internal diameter, the length short tube less than filter core length, and it can wholely be a pipe, also can be the combined type short tube that many little short tubes constitute by an active connection by screw thread or grafting.Be provided with different filtrates in this chimney filter, this filtrate is multiple particulate material, their effect and function have nothing in common with each other, if can activated water, the tourmaline filtrate of microelement-supplementing and mineral matter, and the nanocatalyst filtrate that can sterilize and oxidation resistant negative potential filtrate etc.In chimney filter, be provided with and water passed through and can be with they separated interlayers, as filter or orifice plate.For preventing that filtrate runs off, chimney filter is all established interlayer in two ends up and down.The outside dimension on above-mentioned chimney filter top equals the last locating ring internal diameter size of filtering flask loam cake substantially, makes chimney filter top can be inserted in that both link to each other in the locating ring.Be connected firmly for making, annular groove is established in the junction that is preferably in chimney filter and last locating ring, establishes O-ring seals in the groove.

When running water enters bottle by the loam cake inlet opening, passed the gap that the filter core side enters itself and chimney filter before this.Owing to be subjected to stopping of chimney filter wall, force water to dirty, enter the chimney filter from the lower end of chimney filter, and then from bottom to top filter through the multilayer filtrate, get rid of from the apopore of loam cake, enter in the next filtering flask.

The utility model compared with prior art has following advantage:

1, improves the imbalance that filter the filter core side, made full use of the filtering surface of filter core.

2, chimney filter makes the filter run of water increase several times, so clean-up effect is remarkable, can reduce the filter of series connection for this reason, reduces cost reduced volume.

3, adopt media filtration not only water to be purified, but also can replenish multiple composition, make it to become the high-energy direct drinking the human body beneficial.

4, make full use of the space of existing filter core, make it each several part and all be fully utilized.

Description of drawings:

Fig. 1 is that the utility model filtering flask master looks generalized section.

Fig. 2 is that the two filtering flask masters of the utility model look generalized section.

Fig. 3 is that the utility model three filtering flask masters look generalized section.

The specific embodiment is looked in the generalized section the master of the household water filter filtering flask of sleeve type filter core shown in Figure 1, locating ring 2 and concentric with it lower sealing ring 3 are set in the middle part at the bottom of 1 bottle of this filtering flask, are provided with in the upper shed of bottle to be threaded with it and by the loam cake 5 of two O RunddichtringOs 4 sealings.Loam cake one sidewall is provided with inlet opening 6, and the middle part sets out water hole 7, and it leads to the loam cake opposite side.Loam cake middle part apopore is established locating ring 8 on the evagination that is connected as a single entity with it, also is provided with the evagination upper sealing ring 9 concentric with last locating ring in this loam cake.Filter core 10 upper end perforates are enclosed within outside the locating ring, and the upper surface contacts with upper sealing ring, and the perforate of filter core lower end is enclosed within down outside the locating ring, and the lower surface contacts with lower sealing ring.In filter core, establish an external diameter less than filter core internal diameter, length chimney filter 11 less than filter core length, the interlayer 13 that is provided with different filtrate 12 in this chimney filter and their are separated, and chimney filter is all established interlayer in two ends up and down.Chimney filter top is inserted in the locating ring, and both link to each other.Establish annular groove in the chimney filter and the junction of last locating ring, establish O-ring seals 14 in the groove.Master at the two filtering flasks of the household water filter of sleeve type filter core shown in Figure 2 looks in the generalized section, and two filtering flasks that structure is identical with Fig. 1 become pair filter flask combined water purifying devices by connector 15 series connection between two bottles.Master at household water filter three filtering flasks of sleeve type filter core shown in Figure 3 looks in the generalized section, and structure three filtering flasks identical with Fig. 1 are by two connectors series connection becoming three filter flask combined water purifying devices 16 between them.
