Abstract
Disclosed is a dust collector, which comprises a shell body, a motor, fan blades and a filter, which is characterized in that the motor is mounted in a cavity at the back portion of the shell body, an output shaft of the motor is equipped with the fan blades for discharging airflow, the fan blades and the motor inside the cavity are longitudinally arranged, the fan blades are at least equipped with oblique blade surfaces for pressing the airflow at an inlet of the cavity to the motor, and the fan blades are further provided with approximately vertical blade surfaces for leading the airflow in the cavity out of an air outlet at the back portion of the cavity. The dust collector with a simple and reasonable air cooling structure has the advantages of cooling the motor, circuits and batteries during working process by employing the airflow, thereby avoiding overheating, achieving protection effect and prolonging service life.
Description
Technical field
The utility model 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 in the utility model provide a kind of can to motor carry out air-cooled, avoid overheated, simple and reasonable dust catcher.
The utility model 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, install 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, advantage of the present utility model is: the air-cooled structure advantages of simple, and 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.
