Description

The Pneumatic floor brush that is used for vacuum cleaner

Technical field

The utility model relates to a kind of parts of dust catcher, relates in particular to a kind of Pneumatic floor brush that is used for vacuum cleaner.

Background technology

As shown in Figure 6, Pneumatic floor brush generally comprise housing, rotationally be arranged on that brush in the housing rolls, is connected on the housing and with the suction pipe connector of housing intracavity inter-connection, housing is provided with impeller in the cavity between suction pipe connector and round brush, the lower bottom part of housing offers air inlet, between round brush and impeller, also be provided with and drive the transmission mechanism that round brush rotates, when air-flow from the air inlet that is positioned at the bottom when entering the inner chamber of housing, impeller is driven rotation, and then realizes that round brush rotates.Such Pneumatic floor brush is when work, round brush is involved in dust catcher inside with the large volume dirt on the cleaning face, the air-flow of dust-laden is sucked in the dust collector host from air inlet to be filtered, clean gas flow after the filtration is discharged outside the main frame in dust catcher, though having, this Pneumatic floor brush dust on the cleaning face and dirt can be cleaned together, but in the dust suction process, because dust catcher inside all is negative pressure, the cleaning face that is cleaned like this is if as carpet, the place of bed clothes and so on, these cleaning faces will become uneven after the dust suction, also need further to put in order.

The utility model content

The purpose of this utility model provides a kind of removably Pneumatic floor brush of arrangement brush that has in the bottom.

In order to achieve the above object, the utility model has been taked following technical scheme: a kind of Pneumatic floor brush that is used for vacuum cleaner, comprise housing, be connected the suction pipe connector on the housing, be provided with round brush in the described housing, described round brush is fixed on the mandrel and by this mandrel and is arranged on rotationally in the described housing, the bottom of described housing offers opening, this opening faces described round brush, bristle on the described round brush extends outside the described housing by this opening, and described housing also detachable must being provided with on the outside wall surface that is positioned at its bottom is used for arrangement that the cleaning face is further put in order and brushes.

The bottom of described housing is provided with removably bottom, is formed with brush holder on this bottom, and described arrangement brush is fixed on this brush holder.

The utility model compared with prior art has following advantage: by dismountable arrangement brush is set at housing bottom, Pneumatic floor brush the time not only can be realized the effect cleaned in work like this, and the cleaning face further can also be put in order (arrangement can be with on the carpet the hair combing neat, also can be that rough arrangement is smooth), and the arrangement brush is dismountable, like this when Pneumatic floor brush in cleaning those do not need further arrangement cleaning faces (as the floor) and so on local time, just the arrangement brush of housing bottom can be disassembled and uses as common Pneumatic floor brush.

Therefore, Pneumatic floor brush of the present utility model has not only increased the function of further the cleaning face being put in order, and the structure of part detachable, makes a scrubbing brush can act on multiple scrubbing brush and uses, and realizes multi-functional advantage.

The specific embodiment

Below in conjunction with accompanying drawing an embodiment of the present utility model is described in detail:

Pneumatic floor brush shown in Fig. 1～2, from visual observation, it has a housing 1, suction pipe connector 2, round brush 3.

This housing 1 is made up of the loam cake 11 and the lower cover 12 of mutual engaging, and loam cake 11 and lower cover 12 are fixedly connected by the cooperation of the projection on it and draw-in groove and fixed screw.Suction pipe connector 2 be installed in housing 11 rearward end and with the intracavity inter-connection of housing 1.The lower bottom part of lower cover 12 offers opening 4.

Round brush 3 is arranged in the inner chamber of housing 1, and the bristle 31 on the round brush 3 extends outside the housing 1 by this opening 4, when round brush 3 rotates, extends housing 1 outer bristle 31 and just the foul on the cleaning face can be taken up.

The bottom of lower cover 12 is provided with the arrangement that is used for the cleaning face is further put in order and brushes 5, and as shown in the figure, this arrangement brush 5 has the brush tooth 51 of two row's roundlet tapers, and this arrangement brush 5 that has two row brush teeth 51 generally is used in shag carpet is carried out making in order of hair.(what arrangement brushed setting sometimes is some bristles, also might be the cleaning cloth as rag, is with which kind of arrangement brush can select according to concrete clean Surface the end of specific to.) as shown in Figure 3, the bottom of lower cover 12 is provided with dismountable bottom 6, a plurality of brush teeth 51 are separately fixed on two row's pedestals 52, and brush holder 54 that pedestal 52 is installed and a plurality of through holes 53 that are used to pass the brush tooth are set on the bottom 6.When assembling, at first will brush tooth 51 is fixedly mounted on the brush holder 54 and will brushes tooth 51 together with pedestal 52 and pass through hole 53, base 6 is clamped on the bottom of lower cover 12, this Pneumatic floor brush is when work so again, and a plurality of brush teeth 51 just can further be put in order the cleaning face.Brush in fact tooth 51 also can quadric injection mould pedestal 52 (quadric injection mould former because the material of brush tooth 51 and pedestal 52 is different, brush tooth 51 is soft with respect to pedestal 52), to be removably mounted on by the arrangement brush 5 that the brush tooth 51 and the pedestal 52 of one are formed like this and can realize the 5 dismountable installations of arrangement brush on the brush holder 54, when not needing the arrangement brush or changing different types of arrangement dataller to do, as long as bottom 6 is disassembled from lower cover 12, will put again and brush 5 and take off from brush holder 54 and to get final product.
