Specific embodiment
Embodiment: FIG. 1 to FIG. 3 shows a preferred embodiment of this dust cup of dust collector of the application, with some tradition
Dust cup of dust collector is identical to be, also includes dirt cup shell 1, dirt cup inner casing 2 and dirt cup bottom cover 3.Wherein, dirt cup shell 1 and dirt
The lower end of cup inner casing 2 is round uncovered structure, and dirt cup inner casing 2, which is fixed on inside dirt cup shell 1 and gathers thereon, opens up filter
Dirt hole.Dirt cup bottom cover 3 is detachably secured to the lower end of dirt cup shell 1 and dirt cup inner casing 2, and is formed on dirt cup bottom cover 3
Ventilation hole 3a, ventilation hole 3a are used to connect the inside air duct at motor of dust collector end, and the gas in dirt cup inner casing 2 is enable to pass through
Ventilation hole 3a flows to the inside air duct in downstream and is finally discharged from dust catcher exhaust outlet.Aforementioned dirt cup shell 1, dirt cup inner casing 2
The dust-collecting cavity 4 of approximate Ring-cylindrical being vertically arranged is formed between dirt cup bottom cover 3.
When work, the motor operation of dust catcher inside dirt cup inner casing 2 so that form negative pressure, and the dust in environment is in negative pressure
Successively enter the Ring-cylindrical dust-collecting cavity 4 between inner and outer shell by scrubbing brush and hose under suction, because on dirt cup inner casing 2
Dust filtering hole is offered, so big dust granule cannot be introduced into the inside of dirt cup inner casing 2 and destroy the motor of upstream.In this way, inhaling
The dust that dirt device is drawn all concentrates in the dust-collecting cavity 4 of Ring-cylindrical.
But, tiny dust passes through dust filtering hole and flows to the motor of upstream in order to prevent, preferably inside dirt cup inner casing 2
Fill filter cotton.
The key improvements of the present embodiment are that the upper surface of aforementioned dirt cup bottom cover 3 is fixed by secondary injection molding technique
It is connected with a circle shell sealing ring 5 and a circle inner casing sealing ring 6, wherein inner casing sealing ring 6 is arranged around ventilation hole 3a, and shell is close
Seal 5 is looped around 6 periphery of inner casing sealing ring.The round opening portion of 1 lower end of dirt cup shell is sealed against with shell sealing ring 5, dirt
The round opening portion of 2 lower end of cup inner casing is sealed against with inner casing sealing ring 6.
Because above-mentioned shell sealing ring 5 and inner casing sealing ring 6 are fixed on dirt cup bottom cover 3 by secondary injection molding technique
On.When user, which opens dirt cup bottom cover 3, clears up internal dust, sealing ring will not fall off from dirt cup bottom cover 3, increase just
Benefit.
In addition, the lower surface of above-mentioned dirt cup bottom cover 3 is fixedly connected with air duct in a circle also by secondary injection molding technique
Sealing ring 7, and the interior air duct sealing ring 7 is also arranged around ventilation hole 3a.When practical application, which is installed to dust catcher
After main body, the air inlet port in the inside air duct at motor of dust collector end is sealed against below the interior air duct sealing ring 7, anti-leak-stopping
Gas.
Above-mentioned inner casing sealing ring 6, the interior air duct sealing ring 7 and shell sealing ring 5 radial direction from-inner-to-outer according to
Secondary arrangement.
Dirt cup bottom cover 3 integrally formed with it is between interior air duct sealing ring 7 and shell sealing ring 5 and with 4 phase of dust-collecting cavity
Logical outer air duct connector 3b.When practical application, the dust mouth of floor brush of dust collector end exogenous wind deferent is connected to outer air duct connection
Mouth 3b.
Above-mentioned inner casing sealing ring 6, interior air duct sealing ring 7 and shell sealing ring 5 are rubber material, preferably silica gel material
Matter, naturally it is also possible to be the materials such as PE or PU.
The production of above-mentioned interior air duct sealing ring 7 and shell sealing ring 5 for convenience, in the present embodiment under dirt cup bottom cover 3
Surface forming one encloses the sealing ring forming tank being recessed upwards, the upper surface molding one of dirt cup bottom cover 3 enclose to lower recess another
Sealing ring forming tank.Wherein, interior air duct sealing ring 7 takes shape in the sealing ring forming tank of lower surface, and shell sealing ring 5 forms
In the sealing ring forming tank of upper surface.
In the present embodiment, dirt cup shell 1, dirt cup inner casing 2 and dirt cup bottom cover 3 are plastic material.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented accordingly, and the protection scope of the application can not be limited with this.It is all according to the application major technique
