Abstract
The invention discloses a kind of blower spiral case air channel structure-improved, comprise spiral case, spiral case upper inside is motor room, downside is air channel, be provided with motor in described motor room, motor-shaft extending enters air channel and is provided with impeller, and described impeller comprises leaf dish, upper surface and the soffit of described leaf dish are equipped with blade, and the inner wall surrounding leaf dish outer rim in described air channel is provided with rib.The present invention defines two air channels by inner sinew adding strip in inside, spiral case air channel, and the spiral case air channel above rib is used for the collection of the wind of being come in by motor air channel that blade sucks, and reaches the object of dispelling the heat separately to motor; Spiral case air channel below rib is used for the work air channel of blade, achieves the collection to wind, to the independent pulverizing of leaf.
Description
Technical field
The present invention relates to foliage pressure-vacuum machine.
Background technology
Foliage pressure-vacuum machine is a kind of outdoor burnisher, is mainly used in the cleaning of fallen leaves, collection.The leaf on ground and dust are blown away or are taken in bag by leaf by air draught by blowing by it, and are pulverized before leaf enters bag.
Existing foliage pressure-vacuum machine has generally included main case, fan blade, motor, airduct and gauge tap etc., the fan blade be connected with motor is positioned at the spiral case air channel of main case, it under the drive of motor in spiral case air channel High Rotation Speed the foreign material such as the leaf in suction chamber are smashed, foreign material after smashing are discharged by crumb mouth and are collected in refuse bag, also the heat of motor are sucked spiral case air channel by motor radiating simultaneously.But due to existing foliage pressure-vacuum machine relation due to pressure differential in the spiral case air channel that left and right casing is formed, often the heat of motor is difficult to be inhaled in spiral case air channel, thus cause motor radiating bad, simultaneously in order to meet temperature rise, it is very large that the folded height of motor and specification are all done, and is all a kind of waste to cost and material.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of blower spiral case air channel structure-improved, actual use can be met also the heat of motor well can be shed, based on this, just motor can be fallen a specification, save material and reduce motor cost.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: blower spiral case air channel structure-improved, comprise spiral case, spiral case upper inside is motor room, and downside is air channel, is provided with motor in described motor room, motor-shaft extending enters air channel and is provided with impeller, described impeller comprises leaf dish, and upper surface and the soffit of described leaf dish are equipped with blade, and the inner wall surrounding leaf dish outer rim in described air channel is provided with rib.
Preferably, the center of described leaf dish is provided with the beam barrel protruding from leaf dish upper and lower surface, and the intracavity section of described beam barrel is deltiod.
Preferably, be provided with rib between the outer wall of described beam barrel and leaf panel surface, described rib is arcs of recesses.
Preferably, the blade shroud of Ye Panshang is scroll arrangement around leaf disk center.
Preferably, the edge contour of described blade is the low curves in middle high both sides.
The present invention defines two air channels by inner sinew adding strip in inside, spiral case air channel, and the spiral case air channel above rib is used for the collection of the wind of being come in by motor air channel that blade sucks, and reaches the object of dispelling the heat separately to motor; Spiral case air channel below rib is used for the work air channel of blade, achieves the collection to wind, to the independent pulverizing of leaf.
Compared with prior art, the invention has the advantages that: existing spiral case air channel be divide into two spiral case air channels by the present invention, achieve the independent cooling to motor, solve the present situation of motor radiating difficulty under the impact of pressure differential, also for blower industry provides a brand-new structure, rating of machine can be reduced simultaneously, meet the requirement of energy-saving material-saving.

Detailed description of the invention
As shown in Figures 1 to 5, blower spiral case air channel structure-improved, comprises spiral case 1, and spiral case 1 is connected to form by screw by left casing 1a and right casing 1b.Spiral case upper inside is motor room 1c, downside is air channel, motor 11 is provided with in described motor room, motor-shaft extending enters air channel and is provided with impeller 10, described impeller 10 comprises leaf dish 101, described leaf dish upper surface and soffit are equipped with blade 102, and described air channel inner wall surrounding leaf dish outer rim is provided with rib 12.Inside, air channel divide into two air channels by rib 12, i.e. upper air duct 1d and lower air duct 1e, and the upper air duct above rib 12 is used for the collection of the wind of being come in by motor air channel that blade 102 sucks, and reaches the object of dispelling the heat separately to motor; Lower air duct below rib is used for the work air channel of blade 102, achieves the collection to wind, to the independent pulverizing of leaf.
Ye Pan 101 center is provided with the beam barrel 103 protruding from leaf dish upper and lower surface, and described beam barrel intracavity section is deltiod 104.This deltiod profile is connected to form with the circular arc line being connected two straightways by two parallel straightways, corresponding, motor shaft cross section is also deltiod.Be provided with rib 105 between beam barrel outer wall and leaf panel surface to gain in strength, described rib is that arcs of recesses is to reduce windage.Blade shroud on leaf dish is scroll arrangement around leaf disk center, and simultaneously described blade edge profile is the low curves in middle high both sides, to form good eddy current wind, produces larger suction force.
