Description

A kind of blowing good Backpack type blower of effect
Technical field
The utility model relates to gardens field of tool, particularly relates to a kind of blowing good Backpack type blower of effect.
Background technology
Gardens instrument blower mainly is used for blowing sweeps fallen leaves, road dust, ponding, accumulated snow and forest extinguishing.
Backpack type blower refers to that user can bear the blower of use, the Backpack type blower of present technology is due to Duct design defect, so causing the overall air-out efficiency of blower lower, blower to go out air quantity less, the blowing effect of blower will be caused so poor, especially, time for the foreign material of some heavier-weight, blower is difficult to blow afloat the foreign material of these heavier-weight, and then can not meet the demand of user.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of blowing good Backpack type blower of effect.
The technical scheme that the utility model adopts is: a kind of blowing good Backpack type blower of effect, comprise knapsack seat, the wearing parts being arranged on knapsack seat, the blower body being arranged on knapsack seat and the power supply module being electrically connected with blower body, described blower body comprises machine shell, the air duct assembly being arranged on machine shell and the air outlet tube being connected with air duct assembly, the wind leaf being provided with motor in described air duct assembly and be connected with motor output shaft, described wind leaf comprises fixed head and is arranged on fixed head blade circumferentially, described air duct assembly is greater than the sectional area of air outlet tube for air-out one end away from the sectional area of air outlet tube one end, and between described air duct assembly and fixed head, form a circulating face, the ratio of sectional area and the sectional area of this circulating face that described air outlet tube is used for air-out one end is more than or equal to 0.9.
Adopt above structure compared with prior art, the utility model has the following advantages: away from what the sectional area of air outlet tube one end did, air duct assembly is greater than the sectional area that air outlet tube is used for air-out one end, can effectively improve stream condition like this, improve blowing efficiency, and the ratio of the sectional area being used for by air outlet tube between the sectional area of air-out one end and circulating face is arranged to be more than or equal to 0.9, can effectively reduce the windage that air-flow is formed, make air-flow less through the loss of air duct assembly, and then make blowing effect better.
As preferably, it also comprises pilot lever, described pilot lever is electrically connected with motor, and described pilot lever is arranged on air outlet tube. Arranging a pilot lever, and be arranged on air outlet tube by pilot lever, control is got up more convenient like this.
As preferably, described air outlet tube is provided with an accommodating cavity for accommodating wire, described pilot lever is electrically connected by wire with motor. Because needing between pilot lever with motor to be electrically connected, so just needing wire by both connections, an accommodating cavity is set, such wire just can be arranged on and can not be arranged in air outlet tube and upper airduct in accommodating cavity, the air-out of air outlet tube would not be affected like this so that air-out effect is better.
As preferably, described air outlet tube being also provided with protective sleeve. Because blower needs to blow off the leaf on ground, so air outlet tube is easy to and ground touching, and then make air outlet tube be easy to damage, so being provided with protective sleeve at air outlet tube, can effectively protect air outlet tube like this, increasing the work-ing life of air outlet tube.
As preferably, arranging switchboard in described pilot lever, it also comprises the display module for showing blower parameter, and described display module is connected with switchboard signal. Such user can know the various parameters of blower in real time, and control is got up more convenient like this.
