Abstract

The utility model relates to a combined prefix dust suction head which belongs to the negative-pressure dust extraction device. The combined prefix dust suction head is particularly suitable for the cleanness of the roller of wool spinners, the suction of non-metal dry powder dust in industries such as textile, feed processing, cigarette manufacture, paper manufacture and building material manufacture, etc. and the dust removal in large public places like theaters, department stores, etc. The suction inlet of the combined prefix dust suction head of the utility model is communicated with a dust remover. The combined prefix dust suction head is provided with a bag-shaped piece in the front, a dust-raising unit is fixed at the bottom and a flexible skirt is arranged around the bottom part of the combined prefix dust suction head. The suction inlet of the combined prefix dust suction head is arranged in front of the operator. The combined prefix dust suction head has not only the functions of a common dust suction head, but also the function of effective suction of dust by utilizing the forward inertia of dust.

Description

Combined prefix dust suction head

The utility model relates to a kind of compound forward type negative pressure cleaner head, the parts that belong to negative pressure dust removing device, be particularly useful for wool spinning combing machine for fur roller cleaning, the absorption of the nonmetal dryness dust of industry such as weaving, feed processing, cigarette, papermaking, building materials, and the dedusting of large tracts of land public place such as arenas, shop.

Existing industry and civilian dust arrester often adopt negative pressure to absorb the pattern (see figure 1), and it mainly is made up of dust removal head ［ 1 ］, passage ［ 2 ］ and negative-pressure cup ［ 3 ］.Under the atmospheric pressure effect, form one in the subrange that dust removal head ［ 1 ］ (claiming cleaner head again) communicates with atmosphere and have the air-flow of suction, the floating shape of trip that drives the constant weight certain volume is eliminated thing in the dust-storing bag of passage ［ 2 ］ negative suction jar ［ 3 ］, reaches the purpose of cleaning.

In order to remove the thing that is eliminated attached to the surface, the cleaner head of being everlasting ［ 1 ］ goes up the installing dust producer, is a kind of simple dust producer that is installed on the cleaner head ［ 1 ］ as the hairbrush among Fig. 2.Under power drives, dust producer ［ 4 ］ with produced relative motion by the cleaning surface, be eliminated thing and break away from by the trip of cleaning surface and float thereby make, absorbed then.

The suction inlet of existing cleaner head ［ 1 ］ is in passage ［ 2 ］ and is eliminated between the thing or top (seeing Fig. 1 and Fig. 2), the configuration mode of this suction inlet has significant disadvantages and limitation: when dust producer ［ 4 ］ moves, be eliminated thing and will be pushed away suction inlet, as left situation among Fig. 2, deduster can not be absorbed effectively and be eliminated thing; When dust producer ［ 4 ］ and the linear velocity of being cleared up surperficial relative motion are big, are eliminated thing and are pulled out away from by cleaning surface, dust collection efficiency extreme difference with bigger speed.

Chinese invention patent and utility model patent disclose multiple dust catcher and cleaner head: " textile industry powerful dust catcher " (CN2056427U) " device for elimination of dirt from fibre fleece " (CN1045821A) " the comprehensive dust catcher of flow-type " (CN2084477U) " electric dust absorption head " (GG87202006) " multifunctional household deduster suction nozzle " (CN2078143U) " a kind of vacuum cleaner attachment " (CN2082597U) above-mentioned patent dust collection method is different, also reached certain purpose, but structure is still not ideal enough, mostly can not effectively absorb the bigger quilt cleaning thing of linear velocity, dust can not be effectively absorbed, perhaps the dust and dirt that the direction of motion departs from suction inlet can not be held.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, is cleared up thing, surrounding environment is not caused the compound forward type cleaner head of polluting again and provide a kind of negative pressure cleaner head structure more rationally, effectively to absorb the floating shape of trip.

Task of the present utility model is finished by following technical measures, and in conjunction with the accompanying drawings embodiment is described in detail.

The explanation of accompanying drawing drawing:

Fig. 1 is common suction type dust suction apparatus structure schematic diagram.

Fig. 2 is the common schematic diagram that has the cleaner head of dust producer.

Fig. 3 looks cutaway view for the utility model structure master.

The utility model shown in Figure 3 is made up of body ［ 5 ］, suction inlet ［ 6 ］, pocket shape part ［ 7 ］, flexible skirt ［ 8 ］ and dust producer ［ 9 ］, suction inlet ［ 6 ］ in the body ［ 5 ］ communicates with deduster, the front lower place of body ［ 5 ］ is provided with pocket shape part ［ 7 ］, the fixing dust producer ［ 9 ］ in body ［ 5 ］ bottom is equipped with flexible skirt ［ 8 ］ in its bottom periphery.

During use, suction inlet of the present utility model ［ 6 ］ places the place ahead that is eliminated the thing motion.Below with the cleaning roller be embodiment.When by the rotation of the roller ［ 10 ］ cleared up, dust producer ［ 9 ］ being being swept by the cleaning thing on the roller ［ 10 ］, cleared up thing and stopped by pocket shape part ［ 7 ］ and store to left movement with certain speed.Flexible skirt ［ 8 ］ separates suction inlet ［ 6 ］ and surrounding environment, and make the suction inlet ［ 6 ］ that communicates with negative-pressure cup that a metastable negative-pressure air-flow be arranged, the quilt that this negative-pressure air-flow will be stored in the pocket shape part ［ 7 ］ is cleared up thing in suction inlet ［ 6 ］ sucks the deduster negative-pressure cup, thereby reaches the purpose of dedusting.

The utility model compared with prior art, have rational in infrastructure, applicability is strong, clearance rate is high, more can improve the characteristics of operator's environmental sanitation condition.
