Abstract
The invention relates to an antistatic structure for a dust collector, which comprises a metal fiche which is arranged at a base. Each of the two ends of the metal fiche is provided with a fixing hole, and bolts thread through the fixing holes to fix the metal fiche at a back shell of the base. Two projections facing forward are arranged at the middle part of the metal fiche. When the metal fiche is fixed on the base, the projecting end of a printed circuit board of a back supporting frame connected with the base is disposed at the concave parts at the backsides of the projections, and the swing of the back support frame generates displacement. The metal fiche is connected with a printed circuit board inside the base through a lead. One end of the lead is connected with the bolts which fix the metal fiche, and the other end of the lead is connected with the printed circuit board. Through the connection of the metal fiche arranged at the base with the printed circuit board through the lead, static generated by the shell of the dust collector can be eliminated through the printed circuit board. Meanwhile, the projecting ends of the bottom bar of the back supporting frame are disposed at the concave parts at the backsides of the two projections, so the swing of the back support frame generates displacement, which is convenient for operating the dust collector.
Description
Technical field
The present invention relates to structure of dust collector, particularly relate to electrostatic prevention structure of dust collector.
Using method.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture and various slits.Dust catcher mainly comprises aspirator and suction line composition.Aspirator is arranged in the body, comprises motor and blower fan.Suction line comprises suction nozzle, air intake duct and dust bucket, and the air entry of the oriented under shed of suction nozzle also communicates with dust bucket in the body by air intake duct.The impeller of driven by motor blower fan rotates at a high speed, and the air in the dust catcher is discharged, and forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the suction nozzle dust, rubbish enter dust bucket in the body together with air from the air entry suction and by air intake duct, dust that air is carried secretly and foreign matter filter and accumulate in the dust bucket through filter, air after filtering is discharged to outside the dust catcher body again, like this, just reach the effect of dust out, clean floor.
From the appearance, dust catcher generally can be divided into vertical with horizontal.The approximate jar tubbiness of horizontal dust collector housing, dress disposal box in the thin slightly first half, thick slightly latter half of inner electric machine and blower fan, suction nozzle separate with housing and are connected by long air intake duct, the operation of mobile suction nozzle operation dust catcher.Vertical type dust collector housing approximate circle tubular, inner electric machine, blower fan and dust bucket, suction nozzle are arranged on housing bottom and are communicated with by short air intake duct, and the handle of upwards erectting is arranged at housing top, by the operation of handle mobile shell operation dust catcher.
Fig. 1 is the appearance assumption diagram of a kind of vertical type dust collector of prior art.
As shown in Figure 1, the upright housing 1 of dust catcher comprises bracing frame, dust bucket 2, base 3.Bracing frame is arranged on the base 3, and is made of front support stand 6 and rear support stand 10.Dust bucket 2 is clipped between front support stand 6 and the rear support stand 10, and is arranged on the base 3.Motor and blower fan are set in the cavity of base 3.There is roller 4 both sides of base 3, and there is the suction nozzle 5 that is installed on the housing base 3 in the place ahead of roller 4.The air entry ground proximity that suction nozzle 5 opens wide downwards has round brush in the suction nozzle 5.Suction nozzle 5 is communicated with by the air inlet of air intake duct with dust bucket 2, and the gas outlet of dust bucket 2 is communicated with base 3 inner blowers one side.The central authorities of front support stand 6 are inserted with sweep-up pipe 7, and sweep-up pipe 7 is communicated with the air inlet of dust bucket 2 by flexible pipe 9.There is handle 8 junction of the upper end of sweep-up pipe 7 and flexible pipe 9, and handle 8 is used to pick and place sweep-up pipe 7.Sweep-up pipe 7 is standby pipes, is used for making use carry out the dust suction operation in suction nozzle 5 inconvenience.
When above-mentioned dust catcher turns round, the rotation of motor drives blower fan also produces suction force, suction nozzle 5 or sweep-up pipe 7 aspirate near dust together with air, be sucked the air that has dust into, enter dust bucket 2 in the housing 1 through air intake duct or flexible pipe 9, filtered by dust bucket 2, the air process blower fan behind the filtration dust flows back to the dust catcher outside from the exhaust outlet of housing.
The dust that filters is collected in the dust bucket 2, and dust bucket 2 need often take off cleaning.Dust bucket 2 is fixed between front support stand 6 and the rear support stand 10, and is arranged on the base 3.Movable rear support stand 10 just can take off dust bucket 2.
Fig. 2 is a dust catcher interior section structure chart shown in Figure 1, shows the connection state of the rear support stand 10 take off behind the dust bucket and base 3.
As shown in Figure 2, rear support stand 10 is connected on the back cover of base 3 by bracing frame insertion section 11, and the rear support stand 10 that is connected on base 3 back covers can swing, and swing rear support stand 10 just can pick and place dust bucket.During swing rear support stand 10, the bottom bar 12 of rear support stand 10 is done slight moving.
The dust catcher of above-mentioned prior art, the swing of bracing frame and other are about the friction of parts and move to wait and all can make shell of the dust collector produce static, and generation static can influence the normal operation and the use of dust catcher on the shell of the dust collector.
Summary of the invention
Dust catcher at above-mentioned prior art exists shell of the dust collector to produce the problem of static, dust catcher involved in the present invention is provided with Metallic card on base, Metallic card is connected with printed circuit board (PCB) (PCB) in the base by lead, so that the static that shell of the dust collector is produced is eliminated by printed circuit board (PCB).
Electrostatic prevention structure of dust collector involved in the present invention comprises the Metallic card that is arranged on the base, and respectively there is a fixing hole at the two ends of Metallic card, and screw passes fixing hole Metallic card is fixed on the base back cover.There are two projections forward at the middle part of Metallic card, and when Metallic card was fixed on the base back cover, the jag that is attached at the bottom bar of the rear support stand on the base placed the recess at the Metallic card projection back side, and makes the position sense is arranged in the swing process of rear support stand.Metallic card is connected with printed circuit board (PCB) (PCB) in the base by lead, and an end of lead is connected and fixed screw, and the other end connects printed circuit board (PCB).
Electrostatic prevention structure of dust collector involved in the present invention is connected with the lead of printed circuit board (PCB) by the Metallic card that is provided with on the base, and the static that shell of the dust collector is produced is eliminated by printed circuit board (PCB).Simultaneously, the jag of rear support stand bottom bar places the recess at two projection back sides of Metallic card, and making has the position sense in the swing process of rear support stand, is convenient to manipulating of dust catcher.
