Description

The filter that air purifier is used

Technical field

The present invention relates to a kind of clarifier, relate in particular to a kind of be useful in use on the air purifier, can play the air cleaner that absorbs or dissolve pernicious gas.

Background technology

Air cleaning is the important behave that improves the environment environmental protection, numerous for this reason air purifiers arise at the historic moment, but at present the clarifier majority is that the various filter screens of carrier are formed by multi-layered foamed plastics, these screen packs all have its common shortcoming: the one, and its intensity is very low, can not bear big air quantity by the time impact,. so circulation wind speed, air quantity all are subjected to certain restriction, that is to say that the amount of handling air in the unit interval is restricted, and makes purification efficiency low; The 2nd, the carrier of these filter screens all is cellular foamed plastics, if after using a period of time, various dust stop up it, purification efficiency falls sharply, and just must be cleaned, and these filter screen intensity is very low, be difficult to clean, so have to renew in addition, use cost so just increased.Also there are some to consider to utilize bamboo charcoal to make filter, but owing to there are some masty problems, can push as bamboo charcoal, being shed to one goes, overlapping and extruding causes mutual obstruction, significantly reduced the air exchange amount, the employing cloth bag that also has, but the problem that mutual extrusion is blocked still can not overcome, the consideration that has adopt vast scale bonding agent and the bonding one-tenth piece of the bamboo charcoal of small scale, like this pore of bamboo charcoal is stopped up, in fact this is not the filter that bamboo charcoal (small scale) is formed, but the filter made from bonding agent (vast scale), so actual effect is very poor, thereby all can not form product.

Summary of the invention

Main purpose of the present invention is to overcome the deficiencies in the prior art, thereby develops a kind of intensity height, good filtration effect, the filter that the air purifier that production cost is low is used.

Another object of the present invention is a kind of high efficiency fluid interchanger of exploitation.

Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the filter that a kind of air purifier is used, contain framework, be installed in the rack of framework air intake/outtake surface, be arranged on the filtering bodies in the rack, it is characterized in that: at least one face of described framework is covered with intensive aperture, be provided with air guiding column between aperture at a certain distance, be full of bamboo charcoal particles between air guiding column and the rack.Between aperture and the aperture groove is arranged, block distinguished and admirable to avoid carbon granule to block the air port.The effect of air guiding column is the guiding that had both played air-flow, increases the air exchange amount, can prevent that again the bamboo charcoal grain from pushing and making the filter effect reduction mutually.

Technical scheme of the present invention can also be further perfect, and as preferably, described air guiding column is the hollow cylinder of end sealing, on the wall of described hollow cylinder around upper, middle and lower all be provided with air-guiding hole.Hollow cylinder can be cylinder, square body or other shapes.

As preferably, have axial sulculus along air vent on the described air guiding column outer wall.Axially sulculus have that to be beneficial to air-flow unimpeded, avoid of the obstruction of bamboo charcoal grain to air-guiding hole.Axially the flute profile of sulculus can be arc, square or rectangle.

As preferably, the direction of described air guiding column blind end is provided with at interval.What that is to say the air guiding column blind end arranges that towards the interval described air guiding column is divided into air intake clock and air draught clock, and blind end is the air draught clock facing to the air inlet person, and openend is the air intake clock facing to the air inlet person.Air guiding column can be processed respectively with framework, then air guiding column is installed on the desired location of framework, also can be with air guiding column and the whole processing of framework.

As preferably, the diameter of the air-guiding hole on the described air guiding column is less than the diameter of bamboo charcoal particles.

As preferably, the groove width of the axial sulculus on the described air guiding column is less than the diameter of bamboo charcoal particles.

As preferably, the diameter of described bamboo charcoal particles is 3mm-7mm; Preferable diameter is 5mm.

As preferably, elasticity cassette structure is adopted in being connected between described rack and the framework.At four jiaos of rack or establish a jump ring at a certain distance, in the bayonet socket that snaps in framework.

Because bamboo charcoal can have powerful deodorization when being absorbed with harmful substances, the smelly ability that disappears, and makes with fresh air, and can discharge anion, and prevent biology and material oxidation, make people and pet dynamic, the bamboo charcoal that the great advantage of bamboo charcoal also is to lose adsorption capacity by illumination after, reducible again.

Therefore, adopting the bamboo charcoal grain is that the beneficial effect of the filter used of the air purifier of filtering bodies is:

Simple in structure, easy for installation;

Owing to adopt alternately, plough groove type, at many levels, multi-faceted ventilation support is that carrier loads bamboo charcoal, so do not need the bonding or cloth bag of bonding agent also can avoid bamboo charcoal overlapped, the problem of blocking can be participated in filtration with 100% bamboo charcoal mutually, raising is to the absorption of pernicious gas and dissolve effect, has improved air cleaning efficient;

Intensity is big, can improve unit interval air exchange amount by big wind speed and air quantity, can improve the air cleaning rate greatly;

Available water is washed, and dries to get final product, and reaches the purpose that can repeat multiple use, has improved service life, has reduced use cost.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is further described in detail.

Embodiment:

Filter as shown in Figure 1 to Figure 3, whole framework 2 is a cuboid, the limit is arranged all around, be covered with intensive aperture 21 on the face of framework 2, groove 6 is arranged between aperture and the aperture, 21 of apertures are provided with air guiding column 11 at a certain distance, 12, air guiding column is the hollow cylinder of end sealing, can be cylinder, square column or other suitable multiple shapes, arrangement principle is that air intake clock 12 is arranged at interval with air draught clock 11, dislocation is in the ranks arranged, and its air intake opening is an air intake clock 12, and the air intake sealing is air draught clock 11, its quantity can be decided as required, present embodiment is provided with 25 air intake clocks, 36 air draught clocks, uniform air-guiding hole 13 on the wall of air guiding column, the quantity of air-guiding hole also can be decided as required, present embodiment is depicted as 4 * 3 holes, has axial sulculus 14 along air vent on the air guiding column outer wall, and flute profile can be square, rectangle or circular arc.Be full of bamboo charcoal particles 5 between air guiding column and the rack 3, the diameter of bamboo charcoal particles is 3mm-7mm, and present embodiment adopts 5mm.The diameter of air-guiding hole 13 should be less than bamboo charcoal particles, and axially the groove width of sulculus 14 should be less than the diameter of bamboo charcoal particles 5, in case bamboo charcoal particles stops up aperture.Air intake surface at framework 2 is equipped with rack 3, and rack snaps in the bayonet socket 22 of framework 2 by the jump ring 31 on it, outlet air surface is equipped with photocatalyst filtering net 4, and then loads onto rack 3.Because blocking of alternately orderly arrangement of air draught clock 12 and air intake clock 11 and rack 3 arranged, bamboo charcoal grain 5 each limit free degree are all placed restrictions on, make it to be fixed on certain position, be difficult for moving, so just do not need to use the bonding agent of vast scale bonding, give full play to bamboo charcoal function is dissolved in the absorption of pernicious gas.

Because air draught clock 11 is distributed in the rectangular framework 2 in order with air intake clock 12, make in this cuboid fully exchange of air of each orientation, and all there is the exchange pore upper, middle and lower around each air guiding column, just on this upper strata of ventilation in groove, the middle level, lower floor is a fully exchange of air of each aspect, this structure can be avoided the obstruction that the bamboo charcoal mutual extrusion causes and influence the exchange of air, thereby constructed at many levels multi-faceted aeration structure.

Facial numerous aperture 21 in length and breadth between, and all there is axial sulculus 14 to link to each other between the air-guiding hole 13 of

air guiding column

12,11 and the hole, even air-guiding hole 13 is blocked, because the existence of axial sulculus 14 is arranged, still can link up the channel of whole air-flow exchange, so just construct alternately a slot type, at many levels, multi-faceted filter mounting.

Adopt the present invention, other joins the air purifier that anion generator is formed, and is good to the absorption of pernicious gas and the effect spy that dissolves, the test through authoritative institution, PARA FORMALDEHYDE PRILLS(91,95), benzene, ammonia, the clearance (rate of descent) of TVOC (overall performane organic compound) etc. reaches 88.4%-99.1%, to ETEC, staphylococcus aureus, the antibiotic rate of Friedlander reaches 99%-99.99%, and can fresh air.

Experiment showed, that we take out two filters of prior art and invention technology is placed under the running water flushing, stands intact with the filter of this invention technical support, but is that the multistorey strainer mesh mechanism of carrier is just incomplete with the foamed plastics.
