Description
Technical field
The utility model relates to a kind of intelligent garbage bins, especially a kind of to be packaged for intelligent garbage bin drawing and pulling type refuse bag
The refuse bag of sealing is packaged closing device.
Background technique
With economic fast development, the continuous improvement of living standard, people have higher and higher requirements for health, dustbin
Also it is continuously improved.The opened type dustbin of early application, advantage are that structure is simple, easy to use, production cost is low, but
Have the following problems in use process: rubbish is naked directly to be exposed to the open air in the sight of people, is most unseemly, rubbish is different in bucket
Taste comes out from dispensing port, still can cause secondary pollution to ambient enviroment.The cap-overturning dustbin that later period uses, using foot
It steps on footboard drives push rod and drives bung Unclosing structure, which can open or close under artificial control, using not also being
Easily, since refuse bag is unable to self-closed, rubbish is not only seen when exchanging refuse bag, but also can smell the different of rubbish sending
Taste, especially summer waste odor stench are unpleasant.The intelligent garbage bin used now is general to be opened automatically by sensing device realization
The function of lid, do not have with dustbin and rubbish when garbage throwing it is any contact, other advantage and disadvantage and the basic phase of cap-overturning dustbin
Together.Although plastic garbage bag can be used in above-mentioned three categories dustbin makes rubbish obtain clearing up without staying dirt, but due to rubbish
Bag is unable to automatic packaging, not only sees rubbish when exchanging refuse bag, but also can smell the peculiar smell of rubbish sending, especially summer rubbish
Rubbish peculiar smell stench is unpleasant, is further improved.
To solve the above-mentioned problems, Chinese invention patent application publication No. CN108584238A discloses a kind of refuse bag and beats
Turn-up mechanism and intelligent garbage bin, the first compression bar and the second compression bar respectively can be collapsed refuse bag to the by driving device driving
The delivery position of one fixed edge and the second fixed edge carries out the refuse bag collapsed to delivery position by thermofusion device heat-sealable
Mouthful, thus solve existing intelligent garbage bin without automatic packaging mechanism or can only semi-automatic packing garbage bag and refuse bag be packaged envelope
Mouth leakproofness is not strong, seals unstable problem；But have the following problems in use: first is that due to the first compression bar and
Two compression bars, which intersect, to be arranged in the first fixed link and the second fixed link, the first compression bar and the second compression bar when mobile it is single-ended by
Power, stability is poor, can be deformed when the rubbish of especially refuse bag is heavier, refuse bag is caused not press tightly, and occurs when sealing molten
Constantly, the phenomenon that blow-by.Second is that one jiao due to refuse bag gathering to delivery position is sealed, cause to pull out when sealing
Length it is inconsistent, lead to the biggish pulling force of diagonal angle refuse bag stress of delivery position, or even pull open refuse bag, while also depositing
Drawing motionless problem.Third is that need the substep driving of two motors that could complete when refuse bag collapses, sealing time length, low efficiency,
High production cost is further improved.For this purpose, many manufacturers and knowledgeable people develop and develop, but so far still
There is not comparatively ideal product to emerge.
