Description

A kind of dust cup of dust collector

Technical field

The utility model relates to a kind of dust cup of dust collector, belongs to the dust catcher technical field.

Background technology

The vacuum cleaner dust cup structure is one of critical piece of dust catcher realization dust suction; At present, common dust catcher adopts the cyclone dust cup structure more, is that the utility model patent " cyclone separating dirt cup " (Granted publication number for CN201088546Y) of ZL200720041438.X, the utility model " cyclone type dust cup of vacuum cleaner " that the patent No. is ZL200620101407.4 (Granted publication number be CN2887234), the patent No. are the Chinese invention patent " dust cup of dust collector of twice separation of integral type " (Granted publication number be CN100352393C) of ZL200510049880.2 etc. like the patent No.; The dirt cup of above-mentioned each patent has all adopted the secondary isolating construction; The air that gets in the dirt cup forms spiral air-flow, makes that being mixed in dust in air receives action of centrifugal force and be thrown out of, and then reaches the purpose of separation; But the air-flow of above-mentioned patent all is directly to discharge from the gas outlet usually after separating through cyclone type; The microfilter device that other are set is seldom arranged, though cyclone dust cup can the most of dust that be mixed in air all be separated in the dust-collecting cavity because the continuous flow of air-flow; Still can get into the gas outlet by some thin dirt; Time stops up once the long gas outlet that causes easily, causes equipment fault, thereby has influence on the normal use of dust catcher; Therefore; In order further to improve the air of existing dust cup of dust collector and the separating effect of dust, prolong the service life of dust catcher, need do further to improve to the dirt cup structure.

For this reason; Someone has developed other a kind of improved dust cup of dust collector, sees that the patent No. is the Chinese utility model patent " a kind of Cyclonic dust collector dirt cup " (Granted publication CN201431412Y) of ZL200920121884.0, and this patent adopts polyester sponge and microfiltration sheet two pass filtration channel; Can the air after separating further be filtered again; But this patent structure is complicated, and volume is bigger, and is light inadequately.

The utility model content

The utility model technical problem to be solved is that a kind of simple in structure, easy to assembly and dust cup of dust collector that the control of dust filter effect is good is provided to the above-mentioned state of the art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of dust cup of dust collector; Comprise cup, bottom, filter and bowl cover; Aforesaid cup has air inlet and air outlet, and aforesaid filter is located in the cup, and aforesaid bowl cover is covered on the port of cup; Aforesaid bottom is located on the lower port of cup; It is characterized in that the inboard one-body molded interior bucket that vertically is provided with and axially connects that has of described cup, in this bucket have a tangential get in bucket the whirlwind import and be passed into the whirlwind outlet of bottom of cup, this whirlwind import communicates with aforesaid air inlet; The port of bucket communicates with aforesaid air outlet in being somebody's turn to do, and described filter then vertically is arranged in this interior bucket.

As preferably, described filter can comprise cylindric screen pack and be positioned at the cylindric extra large handkerchief of screen pack.

The preferred following structure of the set-up mode of filter in interior bucket: the bottom of bucket can be provided with a gripper shoe with shirking in said, and described filter is located on this gripper shoe.Further, the bottom of said interior bucket forms L type link slot, and accordingly, described gripper shoe sidepiece forms with aforementioned link slot can shirk the contiguous block that is connected cooperation.

For filter can accurately be located, accelerate efficiency of assembling, the upper surface of said gripper shoe forms and supplies the spacing annular groove of filter bottom.

Be convenient to clear up the rubbish of dirt cup bottom, said bottom is pulled the lower port that button can be located at cup with shirking through an elasticity.

Compared with prior art, the advantage of the utility model is: the bottom of cup is used to collect most of dust rubbish as the whirlwind accumulation area of one-level; Filter is used to collect the dust of fine particle as the secondary accumulation area, and the rubbish that one-level is filtered 98% or more all is filtered inside cup. dust and Hai Pa separate not can secondary to the obstruction of extra large handkerchief; Overall structure is simple, and volume is less, is convenient to install; Simultaneously easy to assembly quick; Again because filter bits in the bucket, take less space, so cup receives the rubbish capacity bigger in integrated with cup.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the dust cup of dust collector in the present embodiment comprises cup 1, bottom 3, filter and bowl cover 21.Cup 1 has air inlet 11 and air outlet 12, and bowl cover 21 is covered on the port of cup, and bowl cover 21 is provided with handle 22, is convenient to from the dust catcher casing, take out.Bottom 3 through an elasticity pull the button 31 can be located at with shirking cup 1 lower port and seal with sealing ring 32.

Like Fig. 4 and shown in Figure 5, the cup 1 inboard one-body molded vertically setting and the axially interior bucket 13 of perforation that have, cup 1 upper surface also is provided with a cover plate 24.In bucket 13 have a tangential get in bucket 13 whirlwind import 16 and be passed into the whirlwind outlet 17 of cup 1 bottom, and whirlwind import 16 is positioned at the below of whirlwind outlet 17.This whirlwind import 16 communicates with air inlet 11, and port 14 of bucket communicates with air outlet 12 in this, is located at a sealing ring 23 on interior barrel the port 14, prevents that gas from going out from bowl cover 21.Filter vertically is arranged in this interior bucket 13.Filter comprises cylindric screen pack 5 and is positioned at the cylindric extra large handkerchief 4 of screen pack 5.The bottom of interior bucket 13 can be provided with the gripper shoe 6 of a circle with shirking, and filter is located on the annular groove 61 of this gripper shoe 6.

In conjunction with Fig. 3 and shown in Figure 5, the dismountable type structure of gripper shoe 6 and interior bucket 13: the bottom of interior bucket 13 forms L type link slot 15, and accordingly, gripper shoe 6 sidepieces form with link slot 15 can shirk the contiguous block 62 that is connected cooperation.For making the for convenience detach and assembling of gripper shoe 6 abilities, gripper shoe 6 bottoms are provided with the rotating part 63 of a confession hand application of force.

In conjunction with shown in Figure 6; The bottom of cup 1 is used to collect most of dust rubbish as the whirlwind accumulation area of one-level, and filter is as the secondary accumulation area; Be used to collect the dust of fine particle; Filter through one-level, the rubbish more than 98% all is filtered in cup 1 the inside, bulky grain dust and Hai Pa separate not can secondary to the obstruction of extra large handkerchief.Overall structure is simple, and volume is less, is convenient to install, and is simultaneously easy to assembly quick, again because filter bits in the bucket, take less space, so cup receives the rubbish capacity bigger in integrated with cup.
