Abstract
The utility model relates to a negative pressure fume purifier, which comprises a casing provided with a fume inlet and a fume exhaust opening. The utility model is characterized in that a concave guide groove component, the back surface of which faces towards the fume inlet direction, is arranged in the casing, and the bottom side of the casing is provided with an oil collecting tray. The utility model has the advantages of simple configuration, long service life, convenient use and maintenance and good purifying effects and is not easy to damage, and blocking phenomena are not produced.
Description
Technical field: the utility model relates to a kind of suction type fume purifier of fume.
Prior art: the patent No. is that 95246457.8 utility model patent discloses a kind of filtering type cooking fume remover, it comprises a casing, one end of casing is provided with an air inlet, the other end is provided with an air outlet, it is characterized in that: be provided with one group of filter of forming with the air inlet steel plate filter screen parallel in the casing with air outlet, the bottom of casing is provided with outage, and this outage connects oil conservator, and casing is provided with access door.The shortcoming one that exists is that this purification body domestic demand is densely covered with the steel plate filter screen, so complex structure cost height; The 2nd, easy-to-rust damages or contamination is stopped up, and maintenance and cleaning are all very inconvenient.
Summary of the invention: the purpose of this utility model is that a kind of suction type fume purifier of fume will be provided, and it is simple structure not only, and cost is low, and long working life, good purification.
The utility model is to constitute like this, and it comprises having the into housing of mouth and exhaust opening, it is characterized in that: be provided with its back side in the housing towards the guide groove assembly that is concavity that advances the cigarette direction.
During work, oil smoke blows to the rear portion of guide groove assembly from advancing mouth from rear side, so, the both sides of each guide groove form air-flow quickly, the guide groove middle part produces negative pressure, because the viscous force and the affinity of oil are stronger, the oil droplet in the oil smoke at first accumulates on the outer wall of guide groove bottom side.And in the dirty two side ends to the guide groove outer wall of the drive of two sidewinds, under the suction of the negative pressuren zone that in the middle part of guide groove, forms, enter guide groove and form oil stream at last, discharge downwards along guide groove by deadweight.
Than existing cooking fume remover, this use is novel because basic building block promptly is the guide groove that is concavity, so structure is very simple.Obviously have low cost of manufacture, windage is little, and is not fragile, do not produce clogging, and long working life and working service be remarkable advantage easily.In addition, our experiments show that another characteristic of the present utility model is the carbonated drink stream or the gasoline stream that quickly spray from the guide groove assembly back side and come can be separated oil or water in moment from mist, and flow velocity is fast more, separating effect is good more.
Description of drawings: figure one is the structural map of overlooking of embodiment.
Figure two is the structural maps of facing of embodiment.
Embodiment: with reference to accompanying drawing, the utility model embodiment comprises having the into housing 3 of mouth 1 and exhaust opening 2, it is characterized in that: the left and right side of housing is perpendicular respectively to be provided with one group of its back side towards the guide groove assembly that advances the mouth direction, is laid with guide vane 8 on the housing internal perisporium.The guide groove assembly is made up of the plurality of rows guide groove 4 that the section of certain distance is concavity that staggers mutually.Just towards between the front-seat two adjacent guide grooves, the groove width S of each guide groove is greater than the space D with row's two adjacent guide grooves for each notch of back one drainage groove.
V-arrangement in the guide groove that adopts among the utility model embodiment, its bottom side is provided with water conservancy diversion fin 6.
For the greasy dirt that favourable collection is separated, above-mentioned housing bottom side is provided with oil extraction through hole 7, and described draw-off tray 5 places oil extraction through hole below.
This use novel structure novelty, reasonable in design, economic and practical, its market prospects are considerable.
