Abstract
A suction cleaner comprises a shell, a motor, fan blades and a filter. The suction cleaner is characterized in that the motor is installed in a cavity at the back of the shell; the fan blades for exhausting the airflow are installed on an output shaft of the motor; the fan blades and the motor are longitudinally arranged in the cavity, and the fan blades are at least provided with slant blade surfaces pressing the airflow at the entrance of the cavity toward the motor and also provided with approximately perpendicular blade surfaces which lead the airflow in the cavity out of the air outlet at the back. The suction cleaner has the following advantages: the air cooling structure is simple and reasonable, and the airflow is used for cooling the motor, the circuit board and the batteries in operation to avoid overheat, thus having the protection effect and prolonging the service life.
Description
Technical field
The present invention relates to a kind of dust catcher.
Background technology
Along with consumer's the consuming capacity and the raising of esthetic requirement, dust catcher obtains a large amount of promotion and application on work family occasion, and dust catcher miscellaneous designs.
As number of patent application be 200610115460.4 Chinese patent " a kind of hand-holdable vacuum cleaner, this vacuum cleaner comprises the elongate nose of rigidity, described nose-shaped member can be with respect to the pivot angles of at least 135 degree of main shaft.Elongate nose can be pivoted to second extended position from first folding position, in described first folding position, the main shaft of described nose-shaped member and described vacuum cleaner is angled abreast and roughly in parallel, thereby allow vacuum cleaner is stored in the very compact overall space, in described second extended position, described nose-shaped member only becomes less angle or not angled with the main shaft of described vacuum cleaner, extend thereby form.Secondly, because described nose-shaped member is a rigidity and elongated, and have dirty air intake, thereby it can be introduced in the narrow space at one end place, and not as known flexible hose extension from the hand-holdable vacuum cleaner of prior art, support with hand thereby need not the user.Its structural design has unique distinction in a lot of places, but a fly in the ointment is, the fan blade of motor adopts fan blade simple in structure, generally the air-flow of cavity import directly can only be directed to the rear portion air outlet, can not cool off motor and wiring board, so, cause dust catcher long service time one, motor and wiring board are hot easily, and influence is normally used, and requires further improvement design.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can to motor carry out air-cooled, avoid overheated, simple and reasonable dust catcher.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of dust catcher, it includes housing, motor, fan blade, filter, it is characterized in that installing in the described housing rear cavity and be provided with motor, the output shaft of motor is equipped with the fan blade that air-flow is discharged, it is characterized in that fan blade and motor are vertically to arrange in the described cavity, and, fan blade is provided with the oblique blade face of the cavity inlet air flow being pressed to motor itself at least, and fan blade also is provided with the vertical blade face of cardinal principle of the cavity air-flow being drawn the rear portion air outlet.
As improvement, described motor is to be fixed in the rear cavity by motor shelf, is convenient to install and fix.
Further improve, described motor is vertically terminal to be fixed with control circuit board by the fixture setting, and wiring board also can effectively be cooled off, and avoids overheated.
Improve, described motor shelf next door is set with the battery pack as power supply, also can obtain effectively air-cooled again.
Improve, described rear cavity import is communicated with the control of dust disengagement chamber of front portion by the air channel of housing side, is vertically arranged with filter in the control of dust disengagement chamber, to obtain good separating effect again.
At last, whole fan blade is made with the vertical blade face of cardinal principle in described oblique blade face, is convenient to production and assembly.
Compared with prior art, the invention has the advantages that: the air-cooled structure advantages of simple, utilize air-flow that motor and wiring board, battery in the work are cooled off, avoid overheated, play the protection effect, increase the service life.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Anticipate as shown in the figure, as herein described laterally is X-axis, vertically is Y-axis, to scheme to be illustrated as standard.This kind dust catcher, it includes housing 1, motor 2, fan blade 3, filter 4 critical pieces such as grade, housing 1 front portion is a control of dust disengagement chamber 5, the housing rear portion is a cavity 6, be provided with motor 2 by motor shelf 7 in housing 1 rear cavity 6, the output shaft of motor 2 is equipped with the fan blade 3 that air-flow is discharged, the crucial part of its invention is that fan blade 3 and motor 2 are arranged along the longitudinal in the cavity, and, fan blade 3 is provided with the oblique blade face 3a of the cavity inlet air flow being pressed to motor itself at least, fan blade 3 also is provided with the vertical blade face 3b of cardinal principle that the cavity air-flow is drawn rear portion air outlet 8, and oblique blade face 3a makes whole fan blade with the vertical blade face 3b of cardinal principle by plastics molding process, be installed in again on the output shaft of motor 2, motor 2 is vertically terminal to be fixed with control circuit board 9 by the fixture setting, motor shelf 7 next doors are set with the battery pack 10 as power supply, at last, rear cavity 6 imports are communicated with the control of dust disengagement chamber 5 of front portion by the air channel 11 of housing side, are vertically arranged with filter 4 in the control of dust disengagement chamber 5.
Its operation principle is such: rotate when motor rotation drives fan blade, the pressure wind by oblique blade face is pressed onto motor itself, wiring board and battery with air-flow, carry out air-cooled, then by the discharge of rear portion air outlet.
Claims (6)
