At first, with the work of 11 explanation first embodiment of the invention with reference to the accompanying drawings.When user's operating vaccum suction cleaners, the drive source that is arranged in this vacuum cleaner main body produces strong suction.When the user was installed in the water of grip (not shown) of extension 10 and/or cleaning agent and sprays handle or button (not shown) with such state of operation, water or cleaning agent optionally sprayed from the sprinkler 30 of the upper surface that is installed in this flooded suction 20.The clean liquid that sprays is sucked back with impurity, air etc. by suction inlet 21.
Guide towards the open gradually spray flow passage 27 of flooded suction front end from the cleaning liquid edge that sprinkler 30 sprays.Then, this cleaning liquid is scatter by downstream rib 24 and is discharged into zone to be cleaned.That is to say that when cleaning liquid flowed to the downstream of spray flow passage 27, the flow width of cleaning liquid increased, cleaning liquid is scatter more equably by downstream rib 24, and finally discharges then.In other words, dirty rib 24 prevent cleaning liquid unordered flow and it flow through run through part 25 between the downstream rib 24, thereby, cleaning liquid entirely scatter and supply with zone to be cleaned.
Only for reference, preferably, the water cleaning attachment is installed in the front end of flooded suction 20.This annex disperse equably cleaning liquid and with produce frictional force when zone to be cleaned contacts, thereby clean.
Then, cleaning liquid and impurity are inhaled into by suction inlet 21 by the suction from this vacuum cleaner main body transmission.Cleaning liquid that is inhaled into by suction inlet 21 and impurity are sent to this vacuum cleaner by extension 10 main body.
Simultaneously, Figure 12 is illustrated in that cleaning liquid is scatter in the second embodiment of the invention.In this embodiment, the cleaning liquid that sprays from sprinkler 130 is scatter by upstream rib 140.Upstream rib 140 at first is directed to cleaning liquid its both sides and therefore disperses cleaning liquid.In addition, cleaning liquid flows through the gap between the lower surface of the upper end of this upstream rib 140 and nozzle cover 126.
Therefore, the cleaning liquid that sprays from sprinkler 130 is at first scatter by upstream rib 140, supplies with downstream rib 124 then.The cleaning liquid of supplying with downstream rib 124 flow through be formed between this downstream rib 124 run through part 125 in scatter.In this embodiment, upstream rib 140 makes cleaning liquid can disperse and supply with downstream rib 124 more.
Secondly, Figure 13 illustrates the work of third embodiment of the invention.In this embodiment, be sprayed onto the center of a large amount of cleaning liquids arrival upstream rib 240 the spray flow passage 227 from sprinkler 230.Because the center of upstream rib 240 forms and is partial to sprinkler 230 relatively and its two ends form and are partial to the downstream, therefore, cleaning liquid is directed along this upstream rib 240.
The part 241 that runs through that part cleaning liquid flows through upstream rib 240 enters space between upstream rib 240 and the downstream rib 224.Remaining cleaning liquid flows to the two ends of upstream rib 240 and by not forming the field flow orientation downstream rib 224 of upstream rib.
The cleaning liquid that runs through part 241 that at first, has flow through upstream rib 240 flows to the downstream rib at the cardinal principle center of downstream rib 224.Because some downstream ribs 224 of core form relative deflection sprinkler 230, and the downstream flank that is arranged on transverse ends forms and is partial to the downstream relatively, can to a certain degree flow to these downstream rib 224 parts that are arranged on transverse ends so flow through the cleaning liquid of the core of downstream rib 224.The cleaning liquid of supplying with downstream rib 224 by this way leaves nozzle assembly and is discharged into zone to be cleaned then by the part 225 that runs through of downstream rib 224.
In addition, the cleaning liquid that supplies to some downstream ribs 224 that are arranged on transverse ends is to a certain degree flowing to its center portion downstream rib.This be since the cleaning liquid at upstream rib 240 two ends of flowing through can not be by being formed on a series of downstreams rib 224 the relevant part 225 that runs through at two ends discharge fully.Specifically, form straight line, in height do not have difference, so flow through the downstream rib 224 that the cleaning liquid at upstream rib 240 two ends can flow to the center from the straight line downstream rib 224 that is arranged on transverse ends owing to be arranged on the downstream rib 224 of transverse ends.
If the user pushes ahead flooded suction 220 in such a way when cleaning liquid is discharged from nozzle assembly, the cleaning liquid that then is discharged at first drops onto zone to be cleaned, and is inhaled into by suction inlet 221 by the inhalation power through the suction inlet transmission with air and impurity then.
At this moment, if additional water cleaning attachment (not shown) is installed in the front end of this flooded suction 220, annex disperses cleaning liquid and equably simultaneously in generation frictional force when zone to be cleaned contact so, thereby cleans.The cleaning liquid, impurity and the air that suck by suction inlet 221 are sent in the main body (not shown) of this vacuum cleaner by extension 210.Cleaning liquid and impurity are collected in this main body, have only air to be discharged into the outside.
The work of fourth embodiment of the invention is described below with reference to Figure 13.The a large amount of cleaning liquids that are sprayed onto the spray flow passage from sprinkler 330 flow to the center of upstream rib 340.Because the center of upstream rib 340 forms and is partial to sprinkler 330 relatively, and its two ends form and are partial to the downstream, so cleaning liquid is directed along upstream rib 340.
The part 341 that runs through that part cleaning liquid flows through upstream rib 340 enters space between upstream rib 340 and the downstream rib 324.Remaining cleaning liquid flows to upstream rib 340 and by not forming the field flow orientation downstream rib 324 of upstream rib 340.
The cleaning liquid that runs through part 341 that at first, has flow through upstream rib 340 flows to the cardinal principle core of downstream rib 324.Because some downstream ribs 324 of core form relative deflection sprinkler 330, and the downstream flank that is arranged on transverse ends forms and is partial to the downstream relatively, so flowed to some downstream rib 224 parts that the cleaning liquid of the core of downstream rib 324 can be arranged on transverse ends at certain Cheng Liuxiang.The cleaning liquid of supplying with downstream rib 324 by this way leaves nozzle assembly and is discharged into zone to be cleaned then by the part 325 that runs through of downstream rib 324.
In addition, the cleaning liquid that supplies to some downstream ribs 324 that are arranged on transverse ends is to a certain degree flowing to its center portion downstream rib.This is because the cleaning liquid at upstream rib 340 two ends of flowing through can not be discharged fully by the relevant part 325 that runs through that is formed on rib 324 two ends, a series of downstreams.Specifically, form straight line, in height do not have difference, so flow through the downstream rib that the cleaning liquid at upstream rib 340 two ends can flow to the center from the straight line downstream rib 324 that is arranged on transverse ends owing to be arranged on the downstream rib 324 of transverse ends.
Yet barrier rib 349 and block piece 349 ' separate straight line downstream rib 324 and curve downstream rib 324, flow through between it to prevent cleaning liquid, thereby scatter more equably and discharge cleaning liquid.
Simultaneously, separated by protector 348 and therefore prevented to supply to dog hole 323h by upstream rib 340 two ends and the cleaning liquid that supplied to a series of downstreams rib 324 transverse ends.Because the front end of nozzle cover has bigger width, so, for the front end that makes nozzle cover 326 contacts closely with flooded suction 320, utilize this structure of hook 326h to be absolutely necessary.
If the user pushes ahead flooded suction 320 in such a way when cleaning liquid is discharged from nozzle assembly, the cleaning liquid that then is discharged at first drops onto zone to be cleaned, and is inhaled into by suction inlet by the inhalation power through the suction inlet transmission with air and impurity then.
At this moment, if additional water cleaning attachment (not shown) is installed in the front end of this flooded suction 320, annex disperses cleaning liquid equably and is side by side producing frictional force when zone to be cleaned contacts so, thereby cleans.
The cleaning liquid, impurity and the air that suck by suction inlet are sent in the main body (not shown) of this vacuum cleaner by extension 310.Cleaning liquid and impurity are collected in this main body, have only air to be discharged into the outside.
The above-mentioned detailed description according to the present invention can obtain following advantage.
Because cleaning liquid is discharged by the upper surface of the flooded suction of nozzle assembly, so the user can clean when the promotion nozzle assembly applies very big power.Therefore, when drawing flooded suction, need the vacuum cleaner of routine more energetically to compare, only need less power, and can more stably clean with the user.
And because the cleaning liquid that sprays from sprinkler scatter by upstream rib and downstream rib, cleaning liquid can offer this nozzle assembly more equably through sending out the zone whole.Therefore can clean the zone of broad simultaneously, the result has improved cleaning efficiency.
In addition, the water of sprinkling is not directly to be discharged into zone to be cleaned, but offers zone to be cleaned through upstream rib and downstream rib, so that for example, when cleaning carpet, the cleaning liquid of sprinkling can reduce the pressure of carpet.Therefore, the cleaning liquid that suitably is sprayed onto carpet surface is inhaled into immediately by suction inlet, thereby has shortened drying time widely.
At last, do not have seepage owing to the edge of nozzle cover in the structure that nozzle cover is fixing contacts closely with flooded suction, therefore, reliability of products further improves.
Scope of the present invention is not limited to the foregoing description, but is defined by the claims.Clearly, those of ordinary skill in the art can carry out various modifications and correction in the scope of the present invention that is defined by the claims.
