Abstract

The utility model concretely relates to a pneumatic vacuum duster, belonging to the technical field of dusters. The utility model comprises a dirt holding barrel, a cover body, a duster, and an air flow direction converter, wherein, the cover body is provided with an air supply inlet, an air outlet, and a vacuum suction opening; the hollow cylinder-shaped air flow direction converter is embedded into the cover body; the both ends of the air flow direction converter are respectively communicated with the air outlet and the vacuum suction opening; the position of the outer wall of the air flow direction converter corresponding to the position of the air supply inlet of the cover body is provided with a circle of concave groove, and the concave groove is provided with a sloping channel which is communicated with the inner hollow section of the concave groove. The utility model can boost the air pressure for a second time. The utility model has the advantages of strong vacuum suction capability, and compact structure, and furthermore, the utility model is suitable for sucking various dust, scraps, and liquid.

Description

Pneumatic vacuum cleaner

The utility model belongs to the dust catcher technical field, is specifically related to a kind of vacuum cleaner of pneumatic type.

At present, dust collection equipment mainly is that driven by power internal impeller or blower fan rotate, and makes air discharge in the dust catcher, forms vacuum, and then reaches the dust suction purpose.This kind equipment complex structure, impeller or blower fan easily contact with the dirt that sucks during work, and collision produces spark, is not suitable for the absorption to inflammable, explosive particle, industrial scrap and water oil.Chinese patent 93224070.4 discloses a kind of " cart type power cleaner ", it by the casing that gathers dust, filter, distribution aspirating mechanism, be located on the case lid, comprise one connect with external compression air source capsule road at the contrary valve of inhaling of general formula; Contrary suction valve is six face closure rectangular cavity bodies, air inlet and a gas outlet that outwards is horn-like extension are established in cavity top, the contrary suction inlet that communicates with casing is established in the bottom, this equipment is through the choose reasonable to threeway oral pore footpath and casing suction inlet aperture, form the contrary suction of vacuum, be used for getting rid of the industrial scrap thing of recovery etc.This technology has the wider scope of application with respect to electric dust collector in the past, but its distribution aspirating mechanism structure is rough, after Compressed Gas enters, and the secondary booster deficiency, the vacuum draw ability is not good enough, and the complete machine structure complexity.

The utility model is at the prior art above shortcomings, purpose is to provide a kind of external compression source of the gas that utilizes, and has that fine secondary booster effect, vacuum draw ability are strong, a compact integral structure, succinct, the pneumatic vacuum cleaner that is suitable for absorbing all kinds of useless dirt, bits.

The technical solution of the utility model is as follows:

The utility model comprises dirt splendid attire bucket, lid, suction port, establish gas source air inlet, gas outlet on the lid and lead to the vacuum draw mouth of dirt splendid attire bucket, also be embedded with an airflow direction converter in the lid, converter is a hollow columnar structures, two ends communicate with gas outlet and vacuum draw mouth on the lid respectively, the relative position of converter gas source air inlet on its outer wall and lid has a circle groove, and has that its inside communicates in this position and towards the slanted channel of gas outlet direction.

Slanted channel on the designed airflow direction converter of the utility model can be oblique aperture.Also establish large knitting needle shape supercharging part in the airflow direction converter, its end is fixed on the lid, and the other end is stretched in the airflow direction converter by the vacuum draw mouth; Seal with sealing ring between airflow direction converter outer wall and the lid.

Suction port of the present utility model is positioned on the lid, and lid is gone into formula with dirt splendid attire bucket employing lid and connected.Gas source air inlet is equipped with ball valve, and snap joint is housed on the valve body.

The utility model utilizes aerodynamic principle, when compressed air enters the airflow direction converter, through the slanted channel on the converter, air-flow is turned to and to the further supercharging of air, air-flow is discharged rapidly by exhaust outlet behind the secondary booster, produce negative pressure in exhaust ports, exhaust and the interior air formation pressure reduction of bucket like this, the gas in the bucket is just got rid of through vacuum draw mouth and exhaust outlet.Form a vacuum in the feasible bucket, thereby, reach the dust suction purpose making suction port produce powerful suction.

The utility model is established large knitting needle shape supercharging part in the airflow direction converter, to play the purpose of further supercharging and dredging flow.Lid integrates suction port, gas source air inlet, gas outlet, vacuum draw mouth and airflow direction converter, makes very compact conformation, succinct of dust catcher.Lid is gone into formula with dirt splendid attire bucket employing lid and is connected, and when dust catcher was not worked, because bucket inner air and outer air pressure is identical, lid can take off easily, and when dust catcher was worked, then owing to a barrel inside and outside gland relation, lid can tightly be placed on the bucket.

The utility model has the advantages that: can carry out secondary booster to compressed air, have strong vacuum draw ability, compact integral structure, succinct is suitable for absorbing all kinds of useless dirt, bits and liquid.

The utility model is applicable to any place with compressed gas source.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is pneumatic vacuum and dirt device complete machine structure figure;

Fig. 2 is the airflow direction converter profile of pneumatic vacuum cleaner;

Embodiment:

As illustrated in fig. 1 and 2, pneumatic vacuum cleaner is made up of dirt splendid attire bucket 1 and lid 3 two large divisions, and lid is taked to cover formula with dirt splendid attire bucket and connected.Suction port 2, gas source air inlet 4, gas outlet 7 and vacuum draw mouth 9 all are positioned on lid 3 bodies.Vacuum draw mouth 9 communicates with dirt splendid attire bucket 1.Ball valve 5 is housed on the gas source air inlet 4, snap joint 6 is housed on the ball valve.Airflow direction converter 8 is embedded in the lid 3, and its structure is a hollow columnar, and its two ends communicate with gas outlet 7 and vacuum draw mouth 9 respectively.Have a circle groove 11 on airflow direction converter and the lid on the corresponding outer wall in gas source air inlet 4 positions, have in the groove 11 partly communicate with airflow direction converter 8 inner hollow and towards the oblique aperture 12 of gas outlet direction.Also be provided with large knitting needle shape supercharging part 10 in the airflow direction converter, supercharging part 10 1 ends are fixed on the lid 3, and the other end is stretched in the airflow direction converter by vacuum draw 9.Seal with sealing 13 between airflow direction converter outer wall and the lid.
