Summary of the invention
The utility model purpose is: provide a kind of volume little, simple in structure, simultaneously the cup device for dust of the dust catcher of good dedusting effect.
The technical solution of the utility model is: a kind of cup device for dust of dust catcher, comprise cup and be located at the interior extra large handkerchief filter of cup, the rear end of cup connects the motor casing, and the motor casing is provided with motor air inlet and motor air outlet, and vacuum motor places in the motor casing; The front end of cup is provided with suction inlet, is provided with the air flue that is communicated with suction inlet in the cup; Described air flue afterbody forms the air flue elbow and turns to cup inwall tangent line place, and is communicated with the cup inner chamber; Rear portion in the cup is provided with return gas channel, and aforementioned extra large handkerchief filter separates this return gas channel and cup inner chamber, and return gas channel is communicated with vacuum motor through the motor air inlet simultaneously.
The technical scheme that the utility model is comparatively detailed is: a kind of cup device for dust of dust catcher, comprise cup and be located at the interior extra large handkerchief filter of cup, the rear end of cup connects the motor casing, and the motor casing is provided with motor air inlet and motor air outlet, and vacuum motor places in the motor casing; The front end of cup is provided with suction inlet, is provided with the air flue that is communicated with suction inlet in the cup; Described air flue afterbody forms the air flue elbow and turns to cup inwall tangent line place, and is communicated with the cup inner chamber, and this air flue further passes extra large handkerchief filter simultaneously; Rear portion in the cup is provided with return gas channel, and aforementioned extra large handkerchief filter separates this return gas channel and cup inner chamber, and return gas channel is communicated with vacuum motor through the motor air inlet simultaneously.
The technical scheme that the utility model is more detailed is: a kind of cup device for dust of dust catcher, comprise cup and be located at the interior extra large handkerchief filter of cup, the rear end of cup connects the motor casing, and the motor casing is provided with motor air inlet and motor air outlet, and vacuum motor places in the motor casing; The front end of cup is provided with suction inlet, is provided with the air flue that is communicated with suction inlet in the cup; Described air flue afterbody forms the air flue elbow and turns to cup inwall tangent line place, and is communicated with the cup inner chamber, and this air flue further passes extra large handkerchief filter simultaneously.Rear portion in the cup is provided with return gas channel, and aforementioned extra large handkerchief filter separates this return gas channel and cup inner chamber, and this sea handkerchief filter specifically is tubular, and cylindrical shell spreads to the cup posterior direction; And the return gas channel part is between extra large handkerchief filter and airway walls.Return gas channel is communicated with vacuum motor through the motor air inlet simultaneously.And described air flue axis and vacuum motor dead in line.
The utility model advantage is:
1. in the utility model, because suction inlet is located at the cup front end, and the air flue of connection suction inlet passes from cup inside, has simplified layout, has saved dirt cup inner space; And this air flue further passes extra large handkerchief filter, and its axis and vacuum motor dead in line further make the utility model compact overall structure smoothness, dwindle external volume, adapt to the utilization on portable dust collector more.
2. in the utility model, because air flue afterbody formation air flue elbow turns the design to cup inwall tangent line place, add the design that Shanghai handkerchief filter separates cup inner chamber and return gas channel, form cyclonic separation after making dusty gas enter the cup inner chamber by air flue, cinder falls into dirt cup inner chamber, and thin ash can further be blocked by extra large handkerchief filter; Not only improved dust removing effects of the present utility model, and made full use of the space in the dirt cup, and this dedusting structure compares existing large-scale dust cup of dust collector, be simple and easy to clean.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the utility model specific embodiment.
Wherein: 1, cup; 2, extra large handkerchief filter; 3, motor casing; 4, motor air inlet; 5, motor air outlet; 6, vacuum motor; 7, suction inlet; 8, air flue; 9, air flue elbow; 10, cup inner chamber; 11, return gas channel; 12, airway walls.
