Abstract

The utility model relates to a manpower dust catcher. The main characteristic is that the manpower dust catcher adopts mainspring energy storage equipment and a flywheel speed stabilizing device. A driving gear on the mainspring is connected with the flywheel and a fan wheel by a speed increasing gear. The normal work of the dust catcher can be guaranteed without using electricity. The winding mechanism adopts the press rod mode and the winding mechanism can be driven by hands or by feet. The manpower dust catcher has reasonable structure, and convenient operation and is a energy-saving article for daily use.

Description

Manpower dust catcher

The utility model belongs to dust catcher, particularly a kind of manually driven dust catcher.

Existing dust catcher generally adopts the motorized motions mode, and no electricity then can not use, and the power supply of dust catcher drags line also to bring a lot of inconvenience to the dust suction operation during power-on servicing.The dust catcher that directly drives with manpower can be avoided the above-mentioned short of electricity of electric dust collector, but the manpower that continues drives operation, brings many inconvenience again also for the use of dust catcher.

The purpose of this utility model is to provide a kind of manpower dust catcher of being convenient to operate that does not use conventional energy resource.

Task of the present utility model realizes by following manner: dust catcher is made up of clockwork spring energy storage device, speed increasing gear group, flywheel and dust absorption fan, and clockwork spring drives flywheel through gear up, again the drive fan wheel.

The last bar mechanism of clockwork spring energy storage device can adopt side or overhead type crank by bar on the rotation crank, but this class mode is unfavorable for the lighter dust catcher of weight.A kind of scheme of the last bar mechanism that the utility model provides is made up of depression bar, rack gear and ratchet, the reciprocating motion of depression bar, change rotation into through rack gear, a direction of ratchet assurance gear is rotated the last bar gear that can pass to clockwork spring, and the rotation of another direction then is idle running.

Directly manual operation of depression bar can be connected by connecting rod depression bar with pedal, dust catcher can be placed on the ground and go up the work of bar mechanism with foot-operated driving like this; Also depression bar can be connected with manual lever by connecting rod, dust catcher can be placed on the ground or carry on the back at back and press the action bars use with hand like this.

Owing to used said mechanism, dust catcher can be interrupted under the driving at manpower, works effectively continuously.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a manpower dust catcher main drive gear schematic diagram;

Fig. 2 is bar mechanism structure figure on the pressure lever type;

Fig. 3 is foot-operated dust catcher profile;

Fig. 4 is the manual dust collector profile.

Referring to Fig. 1.Depression bar (not drawing among the figure) drives tooth bar 1 and pumps, and through gear 2, last bar gear 3 makes clockwork spring 4 tighten energy storage.The driving gear of clockwork spring 4 drives flywheel 6 rotation at a high speed through speed increasing gear group 5, drives 8 transhipments of dust absorption fan wheel by gear 7.Entire mechanism can be placed in the top of dust catcher dust absorption fan wheel 8.

The concrete structure of last bar mechanism is seen Fig. 2.Gear 2 is fixedlyed connected with ratchet 9, is held in by the axle sleeve frame on the axle of bar gear 3, and the end face of last bar gear 3 is provided with several ratchets 10, and ratchet 10 is through spring (not shown) and ratchet interlock.Tooth bar 1 moves downward, and gear 2 and ratchet 9 up times are rotated, and drives upward bar gear 3 rotations through ratchet 10 and winds up; Tooth bar 1 moves upward, and ratchet 9 changes counterclockwise.(clockwork spring is provided with conventional detent mechanism, and bar gear 3 does not reverse in the assurance).

Fig. 3 and Fig. 4 show two kinds of structures that go up the bar mode of operation.Depression bar 11 links to each other with pedal 13 through connecting rod 12 among Fig. 3, and the supporting top of depression bar 11 is located at the top of dust catcher 14, and

spring

15,16 guarantees that depression bar 11 and bar tooth 1 reset.Depression bar 11 links to each other with action bars 18 through connecting rod 12 among Fig. 4, and dust catcher 14 is provided with braces 17, can carry on the back to press action bars 18 at back with hand and wind up.

Claims

1, a kind of dust catcher, particularly a kind of manpower drives dust catcher, it is characterized in that the power of described dust catcher and transmission mechanism are by the clockwork spring energy storage device, speed increasing gear, flywheel is formed, driving gear on the clockwork spring energy storage device output shaft is connected through the fan wheel of speed increasing gear and dust catcher, and flywheel is located on the high speed shaft of speed increasing gear.

2, dust catcher according to claim 1, the last bar mechanism that it is characterized in that described clockwork spring energy storage device is made up of depression bar, bar tooth transmission mechanism and ratchet, depression bar 11 is hinged with bar tooth 1, gear 2 teeth engagement on tooth bar 1 and the ratchet 9, gear 2 and ratchet 9 coaxial fixedlying connected, and the warp beam sleeve frame be held in bar gear 3 the axle on, ratchet 10 is arranged on the bar gear 3.

3, dust catcher according to claim 2 is characterized in that described depression bar 11 is connected with pedal 13 through connecting rod 12.

4, dust catcher according to claim 2 is characterized in that described depression bar 11 is connected with hand operated lever 18 through connecting rod 12.
