Abstract

The utility model relates to a dusting brush without a power supply. When the dusting brush without a power supply is used, the brush is moved on a carpet to drive a friction wheel on the brush to rotate; a speed-up inertial mechanism in the brush drives a dust suction air pump to fast rotate; consequently, dust objects are absorbed into a dust collecting bin in the brush. The utility model has the advantages of simple structure, low cost and simple operation, which is an ideal energy conservation product.

Description

Dusting brush without power supply

The utility model relates to the absorbent brush field, particularly need not the carpet sweeper device that power supply can dust suction.Existing carpet sweeper is because of all being adopts electronic mode, use cost height.

The purpose of this utility model provides a kind of absorbent brush device that need not power supply, and it has reached the equal effect of small size electric dust collector effectively.

The purpose of this utility model is achieved in that

In use, contact the power that is produced when mobile with carpet surface by the brush next friction drive wheel of shell (1) (11), the speedup inertia gear-box (12) in the transmission brush shell again, last transmission dust suction air pump (8) rotates dust suction.

The utility model is because adopted two groups of speedup clutch gears (14,15) in step-up gear (12), (17,18) alternately increase rotating speed respectively, while is at the coaxial flywheel (10) that is equipped with of air pump (8), so that the rotating speed state that air pump (8) can be kept in balance, thereby realized the dust suction requirement.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1, Fig. 2 are the main body cutaway view and the upward views of a kind of structure of the present utility model.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 according to the concrete device that the utility model proposes.

In this device, brush shell (1) is this body of the brush, detachable dust compartment (2) is loaded on brush shell (1) front portion, steam vent (3) and filter screen (4) are on the dust compartment limit, and bristle (6) is fixed on brush shell (1) bottom, and dust suction is entered hole (7) at middle part, brush shell (1) end, air pump (8) and flywheel (10) are on same axle, advance an one-way cock (5) is housed in the dirt pipeline, friction driving wheel (11) is installed in brush shell (1) rear lower, and gearbox (12) is contained in the brush shell (1).

Fig. 1, Fig. 3, Fig. 4 are the concrete structure device and the working conditions of speed increasing gear in the gearbox of the present utility model (12).

This speedup constructional device divides three grades of speedup transmissions.

The first order is by the speedup transmission that is connected with a joggle of the fluted disc (13) on the axle of friction pulley (11) place and gear (14), the second level is by wheels (14), (15) travelling gear (16), perhaps by gear train (17), (18) travelling gear (19) travelling gear (16) again, the third level is by crown gear (20) on gear (16) power transmission shaft, and last transmission air pump gear (21) makes air pump (8) rotation.

As shown in Figure 3: when fluted disc (13) is rotated in the forward (when brush body is moved to the left, the rotation of friction driving wheel (11) clockwise direction), gear train (14,15) is stressed, and to slide to that gear (16) is meshed be transmission, simultaneously gear train (17,18) disengage gears (19).

As shown in Figure 4: when fluted disc (13) reverse rotation (when brush body is moved to the left, friction driving wheel (11) is rotation counterclockwise), gear train (14,15) will disengage gears (16), and the stressed gear (19) that slides to of gear train (17,18) is meshed simultaneously, again travelling gear (16).Motion so repeatedly, then gearbox (12) increases progressively the effect of inertia of speedup transmission and flywheel (10) by two gear trains (14,15), (17,18) continuous positive and negative alternate, just can reach the even rotating speed identical, drive air pump (8) work simultaneously and reach pick-up performance with miniature motor.

Claims

1, a kind of power supply absorbent brush that need not, it is characterized in that it has a brush shell (1), below brush shell (1), be fixed with bristle (6) and friction drive wheel (11), in brush shell (1), a step-up gear (12) is housed, friction pulley (11) is housed on the power shaft of gear-box (12), flywheel (10) and air pump (8) are housed on the output shaft.

2, by the described device of claim 1, it is characterized in that also being equipped with in the step-up gear (12) two groups of clutch gear groups (14,15), (17,18).

3, by claim 1 and 2 described devices, its thing is levied a friction drive wheel (11) is housed on the power shaft that is gearbox (12), and the device that a flywheel (10) and air pump (8) are constituted is housed on the output shaft.
