The connection of room or the other forms being connected with air blower/common entrance is supplied to nozzle assembly.Round brush passes through on its axis
Motor (usually motor) rotation, the motor work directly or through band or other suitable transmission mechanisms.
Such as with further reference to Fig. 1 as it can be seen that secondary air streams intake assembly 30 is mounted on the front side portion of shell 14, it is generally proximal to
The top of the leading edge 20 of shell and the forward lower edge 32 positioned at substrate.Intake assembly includes multiple openings 34, the multiple to open
Mouth is suitably arranged to the row across the front of round brush and is typically parallel to round brush, passes through the opening, the sky of the amount through adjusting
Gas is from the opening for being drawn onto receiving round brush outside main body 12.As will be described in more detail, secondary air streams particularly exist
Be introduced at the front side portion of round brush so that flowing is advanced along the rotation of round brush, so as under quick flowing by help
It helps removal and removes granular materials.In order to receive enough secondary air streams, the area of opening is preferably relatively large, for example,
In the embodiment illustrated, when nominal 12 English for using the outer diameter for skimming over about 2 inches (25mm) rotated with typical rate
It is the elliptical openings of a row six about 0.5 × 0.65 inch (about 13 × 16.5mm) when the round brush of very little (300mm).However,
It should be appreciated that the opening of various other sizes, shape and quantity can be used, or depending on required air stream, beauty and
Other design factors use single or multiple elongated slots.
Adjustable plate 36 offer secondary air streams are adjustably controlled, the adjustable plate be mounted on the front of shell 14 and
Including opening 38, the opening cooperates to define auxiliary air circulation road 34 with the corresponding opening 40 in shell.Adjustable plate is in length
Sliding motion on degree direction is maintained in track, which is limited at the shell and surrounding of shell by finger engagement block 44
Between frame 42, the finger engagement block is located on the outer surface of adjustable plate with the manual movement of accessory plate, for example, such as may be
When required for the operation of long pile/thickness pile carpet like that, in first position (for example, being seen as left side from Fig. 1), adjusting
Opening 38,40 in section plate and shell is aligned respectively, so that channel 34 fully opens, so that secondary air streams maximize.Work as cunning
When moving to the second position (for example, right side into Fig. 1), opening 38,40 moves into be misaligned each other, so as to closing passage 34,
And to stop secondary air streams, this may be required for the operation on bare floor or low pile carpet.Adjustable plate
It similarly may slide into middle position, partly to open/stop auxiliary air circulation road 34, thus by secondary air streams
It adjusts between the largest and smallest, this may be that various carpets or other floor surfaces are desired or suitable.
As can be seen that the frame 42 for being held in position plate is mounted in the channel mould ordinatedly to shape from Fig. 2 and Fig. 3-4
The front of shell in product 46, the channel moulded parts have channel groove 48, which receives the back edge of frame,
Wherein described two components are suitably glued or are otherwise in connection with together.Figure 4, it is seen that the pendency of frame
End defines the backstop for positioning plate in the end in channel, and wherein the length of sliding channel is longer than the length of positioning plate,
So that form gap 50 at one end or at the other end, movement is slid laterally with allow plate, as shown in double-ended arrow 52.Positioning plate
Lower edge be slidably received in the channel being formed in bottom frame member 54 again (see Fig. 1), the bottom frame member is along ozzle group
The upper leading edge of the substrate 16 of part is installed.
Fig. 5-8 illustrate in greater detail the opening of auxiliary air inflow entrance and round brush and power ozzle air inlet openings it
Between relationship and downwards and the associated flow paths to vacuum inlet below round brush, the vacuum inlet closer to
The rear portion of nozzle assembly.
As described above, and as shown in Figure 5, the internal discharge end of secondary air streams opening 34 is located at nozzle assembly
Round brush 60 is nearby and substantially in the front of the round brush of nozzle assembly.Round brush is located at the suction opening 62 in nozzle assembly bottom again
It is interior, and close to the leading edge 20 of nozzle assembly.Therefore, in fact, the exhaust unit of secondary air streams opening 34 is formed in elongate chamber
Antetheca in, which has suction opening in bottom, and bracket groove 64 formed by the gap between round brush and the antetheca of chamber.Rolling
It brushes the rotary motion of surface in this region and is in downwards then rearwardly direction, as shown in the arrow 66 in Fig. 5, towards vacuum
Air inlet moves backward and pushes particle (referring to Fig. 6).It is different from the mode of paddle wheel, the chamber in front of round brush is entered by opening 34
In secondary air streams hit by other surface characteristics on bristle/blender bar or round brush, and therefore also such as arrow in Fig. 8
It is drawn upward into downwards and in lower section side as shown in 70.This leads to the double influence to power ozzle performance: firstly, by
The secondary air streams impact carpet surface of lower guidance and the partial vacuum for locally reducing 64 lower section of channel opening, reduce and are located at ozzle group
Lower pressure at part front, and the leading edge for therefore alleviating substrate pierces carpet and reduces nozzle assembly in high pile
The resistance moved forward and backward on blanket.Secondly, the downwardly and rearwardly path of secondary air streams enhance and compensate for round brush agitation and
Propulsion movement further helps in and removes granular materials and be located at granular materials direction true at the rear lateral portion of suction opening 62
Empty air inlet 68 back guides.The combination of effect causes machine to be easier to push and manipulate in high/long pile carpet, protects simultaneously
Hold cleaning efficacy that is substantially uncompromising or even enhancing.
In order to help to maximize said effect, the preferably region of constraint or limitation auxiliary air overthe openings, to prevent
Fluid stopping is dynamic to be inhaled into opposite direction, that is, is fallen back ground and is passed through at the top of round brush to vacuum inlet.As can be seen from Figure 8, this
It is realized in the shown embodiment by positioning round brush, i.e., so that the upper forepart of round brush is interior on the adjacent part 72 of shell
Surface positioning, therefore to minimize the gap 74 even being eliminated in the region between both of the above.For example, in illustrated embodiment
In, the gap 74 at chamber is suitably about 0.1 inch (2mm) or smaller, and due to the diverging curvature of round brush and antetheca, lower section
Chamber is broadened before being outwardly opened by base channel to 0.25 inch (6.5mm) or bigger.It should be appreciated that in various embodiments
In, formation or positioning the position for this limitation of air flowing or other limitations or block piece can be with illustrated embodiment
Position it is different.
It should be appreciated that scope of the appended claims should not be limited by specific embodiment as described herein, and Ying Yiyu
The mode that the entirety of specification is consistent is understood.
