Description
Technical field
The utility model relates in general to the suction nozzle of dust catcher, and the suction nozzle is for connecting with domestic vacuum cleaners so as to cleanly
Face.
Background technique
The suction nozzle of dust catcher well known in the art, the suction nozzle are designed to improve the flowing of inner air, such as text
The suction nozzle disclosed in US5953787 is offered, which has hair, and the hair is assemblied on the wall of suction channel.However, the system is outstanding
It has the drawback that the pumping efficiency for destroying dust, because the hair of the inner wall of covering suction nozzle can retain dust, dust accretions exist
Mao Shang.
Utility model content
The shortcomings that the purpose of the utility model is to overcome above-mentioned existing technical literatures, and a kind of suction is especially provided first
The suction nozzle of dirt device, the suction nozzle have good pumped mass.
For this purpose, the first aspect of the utility model is related to a kind of suction nozzle of dust catcher, the suction nozzle is arranged to and inhales
The connection of dirt device, the suction nozzle of the dust catcher include:
Bottom plate；
At least one is formed in the suction channel in the bottom plate,

Advantageously, concave shape has the depth of 0.8mm to 2mm.
Advantageously, concave shape has the characteristic size of 4mm to 6mm.Characteristic size refers to the other of concave shape and wall
The size of partial cross-shaped portion.Therefore can be related to the diameter of hole, or if cross-shaped portion be not it is circular, be related in the hole
Two sides between length.In the case where groove or striped, it is related to its width at the other parts of wall.
Advantageously, concave shape is spaced each other a repeat size, and the repeat size is strictly larger than the characteristic size.It changes
For it, concave shape is not overlapped and is spaced each other.
Advantageously, concave shape is spaced each other a repeat size, and the repeat size is 6mm to 10mm, and more advantageous
Ground is 7mm to 9mm.
Advantageously, concave shape has the shape for being not penetrated depressed section.Therefore wall is not perforation.
Advantageously, the interference mechanism includes multiple prominent shapes, such as blade.
Advantageously, the suction channel includes upper wall and side wall, the side wall be arranged in the bottom plate and the upper wall it
Between, and mechanism is not interfered on the side wall.

Detailed description of the invention
It is retouched by the detailed of the embodiments of the present invention provided in a manner of non-limiting example referring to the drawings
It states, other features and advantages of the utility model will be best understood, in the accompanying drawings:
- Fig. 1 shows the bottom view of the suction nozzle of dust catcher according to the present utility model；
Fig. 2 shows the detail views of the wall of the suction nozzle of Fig. 1；
- Fig. 3 shows the cross-sectional view of the suction nozzle of Fig. 1 at the straight line III-III of Fig. 1；
- Fig. 4 shows the suction nozzle of the prior art, which has stock size identical with the suction nozzle of Fig. 1 and Fig. 3.
Specific embodiment
Fig. 1 shows the bottom view of the suction nozzle of dust catcher according to the present utility model, which has bottom plate 10, the bottom plate
For with ground to be cleaned face contact and including suction channel 20.
Typically, suction channel 20 is arranged on the groove in bottom plate, which has between 15mm and 50mm
Width, the groove extend in the major part of the length of the suction nozzle of about 250mm, and connect with a part of cylindrical conduit,
The cylindrical conduit with the vacuum cleaner hose of domestic vacuum cleaners and aspiration circuit for connecting.
It may be noted that the suction nozzle of Fig. 1 does not include rotating brush, it does not include cleaning steam circuit, therefore be related to a kind of passive yet
Suction nozzle, the passive suction nozzle clean ground by its suction capactity.
For this purpose, when dust catcher work when, suction air flow is applied in suction channel 20, aspirate foul, the foul with
It is collected into the main body of dust catcher afterwards (in bag or cyclone compartment).
It is therefore important that the suction stream for ensuring that there is high air speed, to drive foul as much as possible.For this purpose, root
There is wall 30 according to the suction nozzle of the utility model, which forms suction channel 20, and the suction channel is equipped with interference mechanism, jammer
Structure is hole 40 herein.
Specifically, only the upper part (bottom of the pipeline on the suction nozzle of the overturning in Fig. 1) of suction channel 20 includes these
Hole 40.
The effect of this hole is the air stream interfered near wall 30, this leads to the thickness for increasing the air layer near wall 30
Degree, compared with the wall for the same suction nozzle for not having hole, in the air layer, air velocity reduces.The result is that suction air flow
It should enter narrow by section, and its speed increases (compared with the wall for the same suction nozzle for not having hole).
Hole 40 is arranged on the non-through cavity in wall 30, as shown in Figure 2.If wall is flat, 40 He of hole
Cross-shaped portion between wall be it is round, which can have between 4mm and 6mm, and more specifically between 5mm and 6mm
Diameter (or characteristic size).Depth can be 0.8mm to 2mm.Therefore, it is related to the concave shape of macro-size, the concave shape is dry
Disturb the air-flow flowing near wall.Microcosmic roughness it is not related to, roughness naturally occurring on the surface.
The arrangement of hole 40 can be in quincunx, to be located on wall 30 as far as possible, but is contemplated that other figures.Example
Such as, the distance between each hole 40 is greater than characteristic size, and can be for example 6mm to 10mm, and more specifically between
Between 7mm and 9mm.
In any case, at least the 70% of the upper part of wall 30 is covered by 40 pattern of hole being spaced each other.Preferably, on this
The 80% of surface is covered by 40 pattern of hole being spaced each other.
It is contemplated that the shape different from hole, such as striped or ripple connected in star, to interfere the flowing near wall.It is related to creating
Turbulent flow or interference are built to reduce speed.
As shown in schematical Fig. 3, suction channel 20 is formed by wall 30, and the upper part of the wall includes hole 40, but should
The antetheca 31 and rear wall 32 of wall do not have interference mechanism respectively and do not have hole 40.
Due to the presence of hole 40, the air layer near wall that wherein speed is obviously reduced is limited and is had by dotted line 50
Have a thickness, the thickness be greater than no hole 40 same wall near reduction speed air layer (shown in Fig. 4, and by
Dotted line 50bis limit) thickness.
As shown in figure 4, section Sbis of the section S at the not disturbed place of suction air flow therefore than Fig. 4 is smaller, this ensures
Bigger speed in the case where same traffic.
Therefore the utility model allows the available cross-section of " reduction " suction channel 20, to improve the speed at this, this changes
It has been apt to drive dust by suction stream.
The improvement obtains in the case where non-physical reduction section S, this allows that bulky grain is avoided to rebound on wall 30, greatly
Particle rebounds so that bulky grain can be kept on the ground.
It should be understood that can in the case where not departing from the scope of the utility model being defined by the following claims,
It is assigned to the different embodiments of the utility model described in this specification obvious various for those skilled in the art
Modification and/or improvement.
