Description
Technical field
The utility model relates to garden instrument field, relates in particular to a kind of blowing good knapsack of effect gardens hair-dryer.
Background technology
Garden instrument hair-dryer is mainly used for purging fallen leaves, road dust, ponding, accumulated snow and forest extinguishing.
Backpack type hair-dryer refers to that user can bear the hair-dryer of use, the Backpack type hair-dryer of technology is because design defect now, so air output is less, will cause like this blowing effect of hair-dryer poor, especially during for the heavier foreign material of some weight, hair-dryer is difficult to foreign material heavier these weight to blow afloat, and then can not meet user's demand.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of blowing good knapsack of effect gardens hair-dryer is provided.
The technical scheme that the utility model adopts is: a kind of blowing good knapsack of effect gardens hair-dryer, comprise knapsack seat, be arranged on the wearing parts on knapsack seat, the power module that is arranged on the hair-dryer body on knapsack seat and is electrically connected with hair-dryer body, the discharge pipe that described hair-dryer body comprises casing, is arranged on the air duct assembly on casing and is communicated with air duct assembly, when described hair-dryer body moves with maximum quantity of wind, the ratio of described air quantity and input power is more than or equal to 0.75cfm/w.
Adopt above structure compared with prior art, the utlity model has following advantage: in the time that maximum quantity of wind moves, the ratio of air quantity and power is set for and is more than or equal to 0.75cfm/w, because the blowing efficiency of whole hair-dryer body is improved, blowing better effects if, can blow afloat the larger foreign material of weight on ground.
As preferably, described hair-dryer body is plugged on knapsack seat and by retaining mechanism and the locking of knapsack seat, described power module is plugged on knapsack seat, and described hair-dryer body is provided with the depression of power supply source Module-embedding, and described knapsack seat is provided with heat radiation through hole near power module one side. Hair-dryer body and power module are all arranged on knapsack seat by the form of pegging graft, and by retaining mechanism, hair-dryer body is locked, dismounting is more convenient like this, and hair-dryer body is fixing also more firm, and because power module is the larger parts of caloric value in hair-dryer, so heat radiation through hole is set in knapsack seat corresponding power module position, can greatly improves like this radiating effect of power module.
As preferably, it also comprises joystick, in described hair-dryer body, is provided with blower fan, and described joystick is electrically connected with blower fan, and described joystick is arranged on discharge pipe. A joystick is set, and joystick is arranged on discharge pipe, control so more convenient.
As preferably, described discharge pipe is provided with an accommodating cavity for accommodating connecting line, and described joystick is electrically connected by connecting line with blower fan. Because need to be electrically connected between joystick and motor, so just need connecting line that both are coupled together, an accommodating cavity is set, connecting line just can be arranged in accommodating cavity and can not be arranged in discharge pipe and upcast ventilation pipe like this, so just can not affect the air-out of discharge pipe, make air-out effect better.
As preferably, on described discharge pipe, be also provided with protective sleeve. The leaf on the ground because hair-dryer need to blow off, so discharge pipe is easy to and ground touching, and then makes discharge pipe be easy to damage, so be provided with protective sleeve at discharge pipe, can effectively protect discharge pipe, the service life of increase discharge pipe like this.
