Description

The gas flow path structure of dust catcher
Technical field
The present invention relates to the structure of dust catcher, specifically a kind of gas flow path structure of dust catcher.
Background technology
Dust catcher is a kind of electrical installation for sanitation and hygiene, for removing the dust in ground, carpet, wall, furniture, clothing and various gap.
According to the form class of dust catcher, vertical type dust collector, horizontal (pot type) dust catcher and portable dust collector etc. can be divided into.
The structure of dust catcher comprise substantially import power supply after generate the motor of dust collector of negative-pressure sucking, form the suction nozzle of air path system, dust-collection rigid tube, hose, the gas containing foreign substances such as dusts carried out to the dust collect plant etc. of cyclonic separation, filtration and collection.
Fig. 1 is the vertical profile structural representation of prior art horizontal dust collector; Fig. 2 is the decomposition texture schematic diagram of prior art horizontal dust collector critical piece.As shown in the figure, there is the castor 2 being convenient to dust catcher body movement both sides, vacuum cleaner bottom 1a rear portion, drain pan 1a rear portion is formed and the space of drain pan lid 3 in conjunction with the motor bin 4a of the horizontal dust sucting motor 22 of rear installation, discharges the air discharge grille 19 of pure air after drain pan 1a rear portion is also provided with dedusting.
Drain pan 1a front portion is formed with hose connection 5a.The rear upper of drain pan lid 3 is combined with the upper cover 11a being provided with power button 7, coil winder press key 8 and having button 9 handle 10a.
The space of settling dust-collecting cylinder 12a is formed after drain pan 1a front portion and drain pan lid 3 front portion combine, there is the dust-collecting cylinder 12a of handle 10b and bottom air inlet 6a, top mouth in conjunction with the horizontal filter of content 13 cyclone cylinder 14a, diversion column 15 is formed in cyclone cylinder 14a, the gas outlet 16 of cyclone cylinder 14a and internal filter 13 side thereof, through drain pan lid 3, the air inlet 6b filtering the motor bin 4a that sponge 33 lies on one's side docks, the horizontal air inlet 6a of cyclone cylinder 14a bottom surface tangentially at the bottom of UNICOM's dust-collecting cylinder 12a, through cyclonic separation, the foreign substances such as the dust of dedusting fall in dust-collecting cylinder 12a by the dust mouth 17 of the cyclone cylinder 14a bottom surface other end, for clearance.
Cyclone cylinder 14a top buckle closure has the cover 23a be combined with dust catcher body.
Below in conjunction with Fig. 3, gas flow path of the prior art is described, Fig. 3 is the gas flow path vertical profile structural representation of prior art horizontal dust collector, as shown in the figure, gas containing foreign substances such as dusts enters the anterior hose connection 5a of vacuum cleaner bottom 1a through brush and dust-collection rigid tube (not shown), enter the cyclone cylinder 14a of 13 of oval interior horizontal filter by dust-collecting cylinder 12a bottom air inlet 6a and with tangential direction, the foreign substances such as the dust of larger particles fall in dust-collecting cylinder 12a through dust mouth 17; And air after dedusting is through the filtration of filter 13, from the end mouth of filter 13 after filtration sponge 33 enter the air inlet 6b of horizontal motor bin 4a, by motor bin 4a and there is Noise Reduction steam vent 18 after, finally, the pure air after dedusting is discharged to dust catcher body outside from the exhaust cap 24 at drain pan 1a rear portion, air discharge grille 19.
But dust sucting motor 22 of the prior art and external motor storehouse 4a thereof are horizontally sets, and namely the motor bin 4a of dust sucting motor 22 and outside thereof lies on one's side on drain pan 1a, be unfavorable for the two longitudinal damping; Cyclone cylinder 14a horizontal in dust-collecting cylinder 12a makes dust-collecting cylinder building block many, and tight requirements is higher, and the inadaptable integrated dust collecting cylinder with the bottom air outlet of vertical cyclone cylinder and filter.
Summary of the invention
The present invention is exactly that motor and motor bin are lain on one's side and be unfavorable for longitudinal damping in order to solve in prior art; Particularly be not suitable with the problem of brief integrated dust collecting cylinder, and a kind of gas flow path structure of dust catcher is provided.
The present invention realizes by following technical scheme.
A kind of gas flow path structure of dust catcher, comprise bottom and there is castor, air discharge grille is installed at rear portion, front portion is formed with the drain pan of hose connection, and protect a sidewall to have the motor bin of venthole and the upper cover of dust-collecting cylinder and cover respectively, and be provided with the dust-collecting cylinder that inside is integrally formed vertical cyclone cylinder in drain pan front, and below forms air inlet, formation gas outlet, bottom surface before dust-collecting cylinder; Drain pan rear is provided with the motor bin of at right angle setting dust sucting motor, and forms air inlet in motor bin bottom surface, drain pan is formed with the gas channel being communicated with gas outlet and rear motor bin bottom air inlet bottom the dust-collecting cylinder of front respectively.
The present invention of such design, the motor bin of upright dust sucting motor and the dust-collecting cylinder being integrally formed cyclone cylinder are vertically set on the drain pan of horizontal dust collector respectively, for adapting to structure and the positioned vertical dust sucting motor of novel dust collection cylinder, and the gas flow path structure changed in dust catcher body, improve the service behaviour of horizontal dust collector and the stability of parts.
