As shown in fig. 2 and 4, the dust cup body 35 and the filter 34 are horseshoe-shaped, and the rear parts of the dust cup body 35 and the filter 34 are connected to the support frame 31. The horseshoe-shaped dust cup main body 35 and the filter 34 are matched with other structures for connecting structures, the upper part is reserved with a space for connecting pieces, and the lower arc is unified with the external shape. As shown in fig. 3 and 4, the filter seal ring 2 is provided between the dust cup body 35 and the filter 34. Is isolated from the external space to prevent the internal air flow from leaking out and prevent the invasion of external impurities. As shown in fig. 5, a dust cup upper cover 33 for guiding the air flow to the air outlet is disposed at the rear inside of the filter 34, and a flow guiding plane is formed at the front of the dust cup upper cover 33. The air flow entering the filter 34 flows to the diversion plane in front of the dust cup upper cover 33 and is then directed directly to the upper air outlet, increasing the dust cup air guiding efficiency. As shown in fig. 3, the front airway 38 is formed by combining a main body and an airway cover 312. In cooperation with the dust cup structure, the front air passage 38 is formed by an upper section and a lower section, and the integral dust cup can be exposed by opening the air passage upper cover 312, so that the cleaning and maintenance are convenient.
In other embodiments of the present invention, as shown in fig. 10, the multi-stage dust cup 5 includes a separator cylinder 516, and a separator air outlet 5162 is provided at one end of the separator cylinder 516; a separator holder 517; the separator cylinder 516 is connected with the dust cup shell 510 through a separator fixing frame 517; the separator mount outer cylinder 5171 is mounted above the outlet of the dirt cup air inlet tube 550. Dust enters the dust cup shell 510 along with the airflow from the dust collector air inlet pipe 550, and firstly, the dust is blocked by the outer barrel 5171 of the separator fixing frame to realize preliminary dust fall, so that the primary dust fall is added on the basis of the dust fall of the original separator, and the dust fall effect is enhanced. As shown in fig. 10 and 11, the port of the outer cylinder 5171 of the separator fixing frame is horn-shaped. The horn-shaped port increases the area of the outer cylinder 5171 for blocking external dust, further enhancing the dust settling effect. As shown in fig. 10 and 11, the separator fixing frame 517 is further provided with an inner cylinder 5172, and the inner cylinder 5172 is a conical cylinder, and the diameter of the inner cylinder is gradually increased from the air inlet end to the inside. The inner cylinder 5172 is a conical cylinder, and the cylinder opening is narrower to prevent dust from directly entering, so that part of dust can be blocked, which is equivalent to adding a first-stage dust falling structure. As shown in fig. 11 and 12, a connecting column is arranged at one end of the air outlet 5162 of the separator, and a slot corresponding to the connecting column is arranged between the inner cylinder 5172 and the outer cylinder 5171 of the separator fixing frame; the separator air outlet 5162 is installed between the separator fixing frame inner cylinder and the outer cylinder. The separator air outlet 5162 is tightly attached to the fixing frame outer cylinder 5172 to form a seal, so that dust is prevented from leaking from the separator air outlet 5162 into the dust cup shell 510 again. As shown in fig. 11 and 12, 3 connection posts and corresponding slots are respectively provided. Adopt 3 point connection, both guaranteed the steadiness of connection, be unlikely to the tie point too much again, lead to the dismouting loaded down with trivial details. As shown in fig. 12, the air outlet 5162 of the separator is of an integral two-stage structure, the front section is cylindrical, one section of the cylindrical section is provided with a plurality of small holes, the rear section is a conical barrel with gradually larger barrel diameter, the conical barrel extends out of an annular wall 5164 towards the inside of the separator, and the annular wall 5164 and the inner wall of the separator form a groove 5165. The inlet of the cone is narrower to prevent dust entering the small hole separator from being directly discharged from the air outlet, and a part of dust can be blocked in a groove 5165 formed between the annular wall 5164 and the inner wall of the separator, which is equivalent to adding a first-stage dust falling structure. As shown in fig. 10, a sealing ring 515 is connected to the other end of the separator cylinder 516. As shown in fig. 13, the seal ring 515 has an annular groove, and the end of the small hole separator is inserted into the annular groove. The rubber sealing ring 515 is added after the small hole separator, so that dust in the dust cup shell 510 can be effectively prevented from leaking out of the dust cup shell 510. As shown in fig. 14, the separator cylinder 516 is provided with a circle of dust fall baffle 5161; the baffle 5161 is located behind the aperture. First, dust is blocked by a horn-shaped outer barrel 5171 of a separator fixing frame to realize preliminary dust fall, then the dust is continuously moved forward, a part of dust can be blocked by the back of a baffle 5161 and falls to the lower part of the dust cup, and a part of dust is filtered by small holes on a small hole separator and also falls to the lower part of the dust cup, so that the dust can fall to the second stage of dust fall. In addition, once dust is generated at the bottom of the dust cup, the baffle can fully play a role in blocking down the dust, and the dust is prevented from continuously rising into the separator. As shown in fig. 11, the baffle 5161 is a disk, the back of the disk is a small hole side, and the front of the disk is formed with an annular protrusion. The front of the baffle 5161 is formed with a protrusion, which can further prevent dust from escaping from the baffle 5161 and prevent dust from bypassing the baffle and entering the rear separator small holes.
In view of the above, as shown in fig. 14, in the step of settling dust in the multi-stage dust settling cup, dust enters the dust cup housing 510 from the air inlet pipe 550 of the dust collector, firstly, a part of dust is blocked by the trumpet-shaped outer cylinder 5171 of the fixing frame of the dust collector to realize preliminary dust settling, then, a part of dust is blocked by the back of the baffle 5161 and falls to the lower part of the dust cup, a part of dust is filtered by the small holes on the small hole separator and falls to the lower part of the dust cup, and the dust falls to the lower part of the dust cup, wherein the dust is in a secondary dust settling mode. The dust in the entering aperture, a part is blocked by the air outlet of the front section separator, and can not be directly discharged from the air outlet, and a part of dust can be blocked at the air outlet, so that three-stage dust fall is realized. In addition, the last inner barrel 5172 is narrower in barrel opening, dust can be prevented from directly entering, and a dust falling function can be achieved. In combination, the invention can increase a multi-stage dust falling structure, ensures that the dust cup fully falls dust and prevents the dust from entering other parts of the dust collector.
