One of the contents of work and life; in the past, the dust was blown with a leather tiger or brushed with a brush, but no matter whether it was blown or brushed, the dust was not cleaned but just floated to other places. Therefore, there is a need for a dust removal device that can thoroughly clean up floating dust, is easy to use and has high dust removal efficiency.

Utility model content

In view of this, the purpose of the utility model is to provide a dust removal device, which can thoroughly clean floating dust, is easy to use and has high dust removal efficiency.

The dust removal device of the present utility model includes a vacuum cleaner and a dust removal brush detachably connected with the vacuum cleaner; the dust removal brush includes a hollow brush body, and the top of the brush body is provided with a dust outlet for connecting with the vacuum cleaner. The bottom of the brush body is provided with a dust inlet connected to the dust outlet; the dust inlet is connected with a rotatable brush head with a rotating bearing, the inner side of the brush head is fixedly provided with rotating blades, and the outer side is fixedly provided with bristles; The bottom of the brush body is recessed toward the top to form a dust suction chamber, and the cross-sectional area of the dust suction chamber gradually decreases from the bottom to the top of the brush body.

Further, the vacuum cleaner includes a motor and a stepless speed regulation switch for adjusting the rotation speed of the motor.

Furthermore, the dust suction cavity is in a contracted arched structure.

Further, the bristles are arranged in a circle.

Further, the dust outlet is provided with a filter screen for filtering.

Further, the dust outlet is provided with a connection part for mating connection with the ventilation pipe of the vacuum cleaner.

Further, the dust outlet is arranged at the center of the top of the brush body.

Beneficial effects of the utility model: the dust removal device of the utility model, when in use, firstly connect the dust outlet to the vacuum cleaner, and after starting the vacuum cleaner, the suction force will push the brush head to rotate, and the bristles in the rotating state have strong dust cleaning ability, and the vacuum cleaner also passes through The dust suction chamber sucks the raised dust, so that the floating dust can be thoroughly cleaned; at the same time, the convergent structure of the dust suction chamber greatly reduces the collision strength between the outside air and the inner wall of the brush, which is conducive to the smooth flow of dust-laden air into the dust outlet, reducing The degree of disturbance of the airflow reduces the flying of dust; the utility model has the advantages of simple structure, convenient use and high dust removal efficiency.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model.

Detailed ways

Fig. 1 is a schematic structural view of the utility model, as shown in the figure: the dust removal device of the present embodiment includes a dust collector 8 and a dust removal brush detachably connected with the dust collector 8; the dust removal brush includes a brush body of a hollow structure 1. The top of the brush body 1 is provided with a dust outlet 11 for connecting with the vacuum cleaner 8, and the bottom of the brush body 1 is provided with a dust inlet 12 connected with the dust outlet 11; the dust inlet 12 is connected with a belt rotating The rotatable brush head of the bearing 31, the inner side of the brush head is fixedly provided with rotating blades 32, and the outer side is fixedly provided with bristles 33; the bottom of the brush body 1 is sunken to the top to form a dust suction chamber 1a, and the dust suction chamber 1a The cross-sectional area of the brush body 1 gradually decreases from the bottom to the top; the dust outlet 11 is preferably located at the center of the top of the brush body 1; the bristles 33 can be arranged in a circle, and the center of the circle is located on the axis of the rotary bearing 31; dust suction The chamber wall of the chamber 1a has a smooth transition. Preferably, the vacuum chamber 1a is in a contracted arched structure; when in use, the dust outlet 11 is first connected to the vacuum cleaner 8, and after the vacuum cleaner 8 is started, the suction force will push the brush head to rotate, and the bristles 33 in the rotating state It has a strong dust cleaning ability, and at the same time, the vacuum cleaner 8 also sucks the raised dust through the dust suction chamber 1a, so that it can thoroughly clean up the floating dust; at the same time, the convergent structure of the dust suction chamber 1a greatly reduces the contact between the outside air and the brush body 1. The collision strength of the inner wall is conducive to the smooth entry of the dust-laden airflow into the dust outlet 11, reducing the degree of disturbance of the airflow and reducing the flying of dust.

In this embodiment, the vacuum cleaner 8 includes a motor (not shown in the figure) and a stepless speed regulation switch 7 for adjusting the speed of the motor; The negative pressure will not be described in detail here; the stepless speed regulation switch 7 can be connected to the sliding rheostat to realize the stepless speed regulation of the motor, thereby conveniently selecting the negative pressure required for dust collection, so that the device has stronger performance.

In this embodiment, the dust outlet 11 is provided with a filter screen 4 for filtering; the filter screen 4 plays the role of preliminary filtration, which is beneficial to the cleaning operation of the vacuum cleaner 8, and can also prevent large particles of cultural relics from being sucked in Inside the vacuum cleaner 8.

In this embodiment, the dust outlet 11 is provided with a connecting portion 5 for cooperating with the ventilation pipe 9 of the vacuum cleaner 8; the connecting portion 5 facilitates the connection of the ventilation pipe 9 and can ensure the sealing of the connection; for example, the connecting portion 5 can The top of the brush body 1 extends upwards to form a threaded part, which forms a threaded connection with the ventilation pipe 9 .

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
