Description
Technical field
The present invention relates to a kind of suction nozzle that will be mounted on the family expenses electrovacuum cleaning equipment, for example, vacuum cleaner, electric broom or use vacuum stripping system is used for absorbing from the surface dust and/or liquid and/or chip more.Especially, the present invention relates to have the suction nozzle of improvement absorption tube, it has good character in absorbent properties and nothing aspect making an uproar.
Background technology
As everyone knows, vacuum cleaner, electric broom or similar family expenses electrovacuum cleaning equipment comprise suction nozzle, are used for from surface absorption dust chip or liquid.Be in this part of power device uses word " brush " to define suction nozzle usually.For the purpose of this specification, therefore, term " suction nozzle " and " brush " are considered to be equal to.Be still the purpose for this specification, term " vacuum cleaner " has very wide in range meaning, comprise the mode of passing through to absorb of the special use that is useful on or family expenses carry out the equipment of cleaning.Therefore, term " vacuum cleaner " comprises vacuum cleaner, electric broom, and the so-called vacuum stripping systems of using more, the centralized absorption plant of family expenses or commercial Application and steam transmit or absorption plant.
Basically, the type of initial known brush comprises a substrate, forms at least one substrate channel thereon, and towards the surface opening that will make vacuum cleaning thereon, one absorbing path, it in use fuses with substrate, and is communicated with the substrate channel fluid; And selectively, a nappe, it can be connected with substrate-absorbing path assembly.The other end of absorbing path uses rotatable joint to be connected with suction line usually.Selectively, in use, fuse in suction nozzle place absorbing path and nappe.
For fear of to misunderstanding, hereinafter will provide some definition about some expression of often using in declarative procedure of the present invention and the claim.These definition also can be later specifically adopted in reference to the accompanying drawings once more.
-word " absorption tube " will be used for expression, being used for the suction nozzle of vacuum cleaner, and by substrate channel, the assembly that absorbing path and rotatable joint constitute.
-word " rotatable joint " will be used for expression, be used for the suction nozzle of vacuum cleaner, have the channel part of closed section, and it forms the extension of absorbing path, and stop with flange (be generally circle, but not necessarily).Usually, suction line is connected to described flange or air-breathing motor is connected directly to this place.Rotatable joint is hinged and forms a pipe section, and this pipe section can tilt in variable mode with respect to the surface that will be swept.
-" inlet-duct area of absorption tube " will be interpreted as such meaning, its essence is and " marking " of wanting the surperficial corresponding lip-deep substrate channel of vacuum cleaning.
-" discharge area of absorption tube " will be interpreted as such meaning, its essence is the area that forms by near the cross section the flange that forms the suction nozzle termination.
" width " of-suction nozzle will be interpreted as such meaning, not have the maximum volume (or ground marking) of the suction nozzle of nappe, and think basic parallel with the longitudinal axis of substrate channel.
-" absorption efficiency " will be interpreted as the meaning of ratio, with the percentage expression between thing that has absorbed and the thing that will absorb.The indication that provides according to 3.2 editions CEI-IEC60312 standards in May, 2004 is carried out and is absorbed test.
-" nothing is made an uproar " that be used for the suction nozzle of vacuum cleaner is that the relative and independent vacuum cleaner of sound level according to the combination of brush and vacuum cleaner is increase or reduces to define.It is big more to have the brushless relatively vacuum cleaner of the noise of vacuum cleaner of brush, thinks that then the noise of suction nozzle is big more.Though can obtain different types of suction nozzle from market, they carry out the function that absorbs dust or liquid or chip from the surface to have enough effective and efficient manner, and the applicant recognizes the needs of the performance that improves existing absorption pressure head.Especially, the applicant's nothing of having recognized that the increase absorption efficiency and improving existing suction nozzle needs of performance of making an uproar.
