Description

Electric hand tool with dust exhaust apparatus
The present invention relates to claim 1 and the 5 described connectors that have dirt bag or filter tunnel and link to each other to accept the electric hand tool of dirt bag or filter tunnel with electric hand tool.
DE-GM9316626 discloses a kind of electric hand tool with dust exhaust apparatus, its dirt bag or filter tunnel can put by the firm blast pipe that is connected on electric hand tool hermetically, air intake pipe box or fan house can not seal the dirt bits that may flow backwards, the electric hand tool band coupled instinct dirt bag when mobile, and dust and smear metal will enter in air intake pipe box or the fan house.May be in fan house when starting shooting once again stuck blower fan and motor is shut down, cause burning the motor winding, damage electric hand tool or working face.
In addition, also have such harm, after electric hand tool stopped, the dirt bits can retain in air-out pipe box place, as take off the dirt bag, environment around can being thrown to when starting shooting again.
With above-mentioned contrast; be the electric hand tool of the present invention of feature or accept filter bag and the advantage of the connector of dirt bag is with claim 1 and 5; blower fan stops; when being motor shutdown; automatically the air-out pipe box of sealing electric hand tool, the sealing fan house, the dirt bits can not and enter in the fan house against the direction motion of dirt; do not adorn the dirt bag, when starting shooting again also not can to around dish out dirt bits.
As long as dirt bag and connector together break away from workpiece, connector promptly seals its inlet, the danger that does not have the dirt bits to enter when therefore shifting the dirt bag.
Other useful structure of the present invention is seen dependent claims.
Further describe embodiments of the invention with reference to the accompanying drawings.
Fig. 1 is the skiagraph with electric hand tool of the present invention of dirt bag, and Fig. 2 is the amplification profile diagram at Fig. 1 dirt bag position, the view when Fig. 3 shuts down for Fig. 2 motor, and Fig. 4 is the perspective view of connector of the present invention.
Electric hand tool 10 comprises the casing 11 that has handle 12 among Fig. 1, and its handle 12 is equipped with the release knob 13 of power on/off, its afterbody extracting power supply cord 15.
The abrasive disc 14 of band air suction opening 16 is equipped with in the lower end of electric hand tool 10, drives its abrasive disc 14 by the motor rotation of not drawing in detail.In the fan house 20 of abrasive disc 14 tops, handheld electric tool machine shell 11 bottoms blower fan 18 is arranged, it is driven by above-mentioned motor (not shown), behind the electric motor starting, air is bloated from fan house 20 through air-out pipe box 22, thereby form negative pressure abrasive disc 14 times, tear the scrap on the workpiece.Arrow group 36 shows air-flow or aspirate travel direction.
Air-out pipe box 22 is terminal for exporting 24, overlap by flow export aspirate discharge housing 11 and with connector 26, dirt bag 28 is arranged on the connector 26, its dirt bag 28 is by the liftoff socket connector 26 of its sack 30 anticreeps, have towards the last zone of the dirt bag 28 of handle 12 and to connect plate 32, can insert stand frame 34, and stand frame 34 can be loaded on the zone of casing 11 handles 12 with passing.
Fig. 2 amplifies air-out pipe box 22 zones, and connector firmly cover is connected in this zone, and connector 26 has thick anterior 38 just like shown in the figure section line, wall thickness 2-4mm.
Then the first 38 of connector 26 is second portion 40, and its inside and outside radial opening portion strengthens wall thickness 0.2mm gradually.
The axis that the air-flow of discharging is tubular aligning air-out pipe box 22 by the air-blowing effect flows through the rear section 40 of connector 26.
Fig. 3 is relative with Fig. 2, the motor outage, blower fan 18 quits work, so airless is by air-out pipe box 22 and connect 26, owing to there are not exhaust airstream and air-blowing effect, back thin-walled portion 40 flat the contracting of connector 26, and it is sagging under the gravity effect, thereby seal connector 26 and air-out pipe box 22 as flap, dirt bits just can not come out to enter that air-out pipe box 22 is laggard goes into fan house 20, the hidden danger of having exempted stuck blower fan 18 through connector 26 in the dirt bag 28 like this.
Especially at the ambulatory handheld electric tool, in shutdown but have under the situation of vibration, guaranteed that the dirt bits in the dirt bag 28 can not come out to enter the inside of electric hand tool.
There is a collar 42 connector 26 front portions, and it and sack 30 sockets also prevent dirt bag 28 from coming off and tighten.
Fig. 4 is the perspective view of connector 26, and as seen from the figure, it is cylindrical that the forward part 38 of heavy wall has the seal that coincide with air-out pipe box 22, and 40 transition are cylindrical to the rear section backward for it.Rear section 40 loud-speaker tubulars strengthen to peristome, the band dirt air-flow that flows through to slow down, and prevent that thin dirt from flowing out dirt bag 28.
The rear section 40 of connector 26 forms a curved soft pipeline, when not discharging air-flow, does not have that the air-blowing effect is flat to contract saggingly, plays the flap effect.
Sagging position and degree can be by the ratio decisions of connector length and wall thickness.
There is a tear strip dirt bag bottom to pluck dust settling pocket.
