Description
Cross reference to related applications
The disclosure requires the U.S. Provisional Patent Application for the Serial No. 62/408,147 submitted on October 14th, 2016
Equity, which is completely contained herein by reference.
Technical field
This disclosure relates to vacuum cleaner, and more particularly relate to include the vacuum cleaner of air agitation table
Face cleaning head.
Background technique
Vacuum cleaner generate partial vacuum with from surface draw dust, dirt and/or particle to be cleaned (hereinafter
It is referred to as clast).Some vacuum cleaners also utilize air agitation, and wherein forced air stream is discharged from vacuum cleaner to remove
Clast.Existing air agitation vacuum cleaner generally includes single air pump and single-motor, which executes generation
The function of both air agitation stream (for example, forced air stream) and vacuum-flow, from surface removal to be cleaned and to draw clast.
Although existing system is usually effective, there are Railway Projects for these systems.For example, using single-motor and single air
Pump needs complicated pipeline.Particularly, it may be necessary to guidance the portion of air stream from single-motor and single air pump with
Air agitation pressure/stream is provided, and may need to reboot another part air stream to provide vacuum source.It is understood that
Be that the main consideration of vacuum system usually effectively generates vacuum source, and this may cause need it is long and/or complicated
The case where pipeline is to provide desired air agitation pressure/stream for air agitation discharge.This length and/or complicated pipeline can
The cost that can increase vacuum increases the weight of vacuum head and/or increases the size of vacuum head, so that the vacuum head be made not to be suitable for
Some clean applications (such as, but not limited to, cleaning or similar application below sofa).
In addition, may be limited very using single-motor and single air pump with providing both air agitation stream and vacuum-flow
The flexibility and efficiency of empty set system.Particularly, if air agitation pressure/stream is too high, clast may be blown from vacuum inlet
It walks, to reduce the efficiency of system.On the other hand, if air agitation pressure/stream is too low, clast may not be blown to very
Empty entrance, to also reduce the efficiency of system.It will be further appreciated that air agitation pressure/stream amount can depend on
By clean surface and/or by clean clast type.Therefore, for all cleaning ambients, individual air agitation pressure/stream
It can work as efficiently as possible.Using single-motor and single air pump to provide both air agitation stream and vacuum-flow
May need the ratio of air agitation pressure/stream and vacuum-flow is static (for example, fixed).Alternatively, although can adjust
Air agitation pressure/stream and vacuum-flow ratio is saved, but this design may usually require to include (in addition to other component) gas
Flow regulating valve and control mechanism.Barometric damper and control mechanism further increase the cost, complexity, valuableness of vacuum system
Price and size.

At by airflow distribution to one or more air blast exhaust outlet/nozzles 34.For example, using single air blast exhaust outlet/spray
In one embodiment of mouth 34, it is desirable to be evenly distributed across air blast exhaust outlet/nozzle 34 forced air stream.Such as
It is understood that in surface cleaning head 12 including for the available of air path designed by air blast exhaust outlet/nozzle 34
Space is very limited.Preferably without using conventional air pipeline or hose, pumping chamber 42 be can permit can
Being uniformly distributed for forced air is realized in the confined space.In order to realize that forced air, which is uniformly distributed in air blast, to give off
Mouth/nozzle 34 uses pumping chamber 42.Pumping chamber 42 can be the pressurization holding part containing barotropic fluid.The function of pumping chamber 42
Equilibrium usually is carried out to the pressure for the air stream for passing through air blast exhaust outlet/nozzle 34 entrance and/or outlet, so that air blast
Exhaust outlet/nozzle 34 substantially evenly discharges air.It pumping chamber 42 can also be by reducing undesired/unexpected noise
To provide acoustic benefit.
When designing pumping chamber 42, it usually needs understand the concrete restriction condition for application.For surface cleaning head 12,
One restrictive condition is space.Good distribution is preferably realized in a limited space.Consider dimensionless group (A/a)；This is
The ratio of the cross-sectional area " a " (Figure 13) of the cross-sectional area " A " (Figure 13) and fluid outlet of pumping chamber.If the face of pumping chamber 42
Product is sufficiently large for use as reservoir, then the effect of the pressure in pumping chamber 42 is by approaches uniformity, and therefore causes substantially evenly
Distribution is from air blast exhaust outlet/nozzle 34 air.In this way it is possible to independently of lead to one of pumping chamber 42 or
Shape, size and the position of multiple entrances and be substantially evenly distributed through air blast exhaust outlet/nozzle 34 air.
One group of simulation 1400 has been carried out to find preferred ' A/a ' ratio in applicant, is discharged with realizing from air blast
The desired Flow Field Distribution of outlet/nozzle 34 generally illustrates the result of the simulation 1400 in Figure 14.As can be seen,
Parameter is used to quantify the Flow Field Distribution for being known as " velocity uniformity index (g) ".Evenness index (g) indicates specifying variable
How (in the case, speed) changes with surface；Value 1 indicates highest uniformity.Applicant has unexpectedly determined
Ratio " A/a " is 4 or bigger, realizes that desired velocity uniformity index (g) is about 0.8 or bigger.Particularly, applicant has been
Unexpectedly it has been determined that ratio " A/a " is 5 or bigger, realizes that desired velocity uniformity index (g) is about 1.0.
Pumping chamber 42 can also optionally include one or more baffles 44 (see, for example, Fig. 7).Baffle 44 can also be helped
It helps cutting and/or is distributed through air blast exhaust outlet/nozzle 34 forced air.It, should be every for example, baffle 44 may include partition
Plate at least partly extends between the upper surface and/or lower surface of pumping chamber 42.Depending on the position of baffle 44, size and take
To forced air can be guided in one or more directions, to allow substantial equilibrium air stream.
It should be understood that, it is desirable to generate the substantially uniform drum across all air blast exhaust outlet/nozzles 34
Wind agitation stream, in some cases, it is desirable to which there is non-uniform distribution.For example, it is desirable to increase further from true
Sky in the region (transverse edge 48a, 48b (for example, as seen in figure 3) of such as surface cleaning head 12) of empty entrance 25
Air-flow.Particularly, it is desirable to increase the air stream in these regions 48a, 48b, to help to enter clast towards vacuum
Mouth 25 moves and/or is substantially prevented from clast and escapes into except surface cleaning head 12.It can be by adjusting pumping chamber 42, baffle 42
And/or one or more of air blast exhaust outlet/nozzle 34 realizes desired air blast agitation flow distribution.
