Abstract
The utility model relates to a part of a cleaning tool, especially a vacuum cleaner vacuum tube and in particular relates to a bend sealing mechanism of a vacuum cleaner. The bend sealing mechanism comprises a bend, a hose, a hose coupler and a retainer ring, wherein hose coupler is arranged at the joint of the bend and the hose and has a sealing effect; and the retainer ring is sleeved in the hose to connect the hose and the bend. The bend sealing mechanism is characterized in that a flanging is arranged at the head of the hose coupler and is in interference fit with the cylindrical surface of the inner wall of the bend in the peripheral direction. The bend sealing mechanism is simple in structure, good in sealability, long in service life, good in effect and convenient to manufacture.
Description
Technical field
The utility model relates to a kind of parts of cleaning device.Especially a kind of dust collecting tube of dust collector, specifically a kind of bend pipe sealing mechanism of dust catcher.
Background technology
Dust catcher has become the household electrical appliance that western countries are generally used now, almost popularizes in each household family, and market is very wide.
The flexible pipe sealing system of dust catcher generally all adopts the sealing means of the rubber ring of bend pipe and hose transition, but due to friction for a long time between rubber and seal, is easy to wearing and tearing and loses sealing function, produces to leak out and reduce dust-absorbing function.Visible, existing dust catcher brings and uses impact to the consumer owing to there being above-mentioned defect.For above-mentioned defect, the flexible pipe sealing system of dust catcher is improved to design and there is realistic meaning.
In addition, dust catcher is constantly pulled back and forth due to sweep-up pipe in the course of the work, and there is frequent bending situation in flexible pipe, and after long-term the use, cracking especially easily appears in the connecting portion of the flexible pipe of sweep-up pipe and bend pipe, and dust catcher often can't use because of the flexible pipe cracking.This defect has been brought inconvenience and has brought worry to manufacturer to the consumer.Visible slight flexible pipe has but become the critical position of dust catcher.Therefore, caused people's attention, the insider manages these parts are implemented to improve.
Summary of the invention
The purpose of the utility model is to disclose the bend pipe sealing mechanism of the effective a kind of dust catcher of a kind of simple in structure, easy to make, good airproof performance, long service life to society.
Technical solution adopted in the utility model is such:
A kind of bend pipe sealing mechanism of dust catcher, comprise hose coupling that bend pipe, flexible pipe, bend pipe and flexible pipe convergence part seal, be inserted in flexible pipe the collar that flexible pipe and bend pipe are caught; It is characterized in that, the head of described hose coupling is with flange, this flange and described bend pipe interference fit.
Be " V " font angle between the head of described flange and described hose coupling.
The structure of described hose coupling back segment is to also have a tubule in a bassoon, the front end closure of described this section large and small pipe, this tubule inserts the inwall of described flexible pipe, and the outer wall of described flexible pipe is entangled in described bassoon, and described flexible pipe front end withstands on the front end sealing part of described large and small pipe.Hose coupling solves the sealing problem of dust collecting tube of dust collector.
Described hose coupling by good springiness, there is good toughness, rigidity, the HDPE high-density polyethylene plastics that cold-resistant, heat-resisting, wear-resisting, chemical stability is good is made.Solved better the problem of sealing, wear-resisting, long service life.
The measure of taking for the optimization technique scheme also has:
The connecting portion back lower place of described bend pipe and collar all is provided with the extension of a shade shape cooperatively interacted, and the extension of the shade shape of this collar and the connecting portion arc outer wall of described flexible pipe are suitable.
Taked above-mentioned technical measures, compared with prior art its advantage is:
Due to the head of described hose coupling with flange, this flange and described bend pipe interference fit, " O " shape sealing ring that replaces rubber to make with such hose coupling, solved " O " shape sealing ring defect easy to wear.
Be " V " font angle between the head of this flange and described hose coupling, increased the tension of this flange on the elbow internal wall circumferencial direction, the sealing property of hose coupling is strengthened.
Due to hose coupling by good springiness, there is good toughness, rigidity, the HDPE high-density polyethylene plastics that cold-resistant, heat-resisting, wear-resisting, chemical stability is good is made, further strengthened sealing property, the anti-wear performance of hose coupling, significantly extended service life.
The connecting portion back lower place of bend pipe and collar all is provided with the extension of a shade shape cooperatively interacted, and can prevent flexible pipe damage jackknifing, thereby can guarantee the good dust suction performance of dust catcher.

The specific embodiment
Each Reference numeral title in accompanying drawing is:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of bend pipe sealing mechanism of dust catcher, comprise hose coupling 2 that bend pipe 1, flexible pipe 4, bend pipe and flexible pipe convergence part seal, be inserted in flexible pipe the collar 3 that flexible pipe and bend pipe are caught; It is characterized in that, the head of described hose coupling 2 is with flange 21, this flange 21 and described elbow internal wall face of cylinder circumferencial direction interference fit.
Be " V " font angle between the head of described flange 21 and described hose coupling 2.
The structure of described hose coupling 2 back segments is to also have a tubule 23 in a bassoon 22, the front end closure of described this section large and small pipe 22,23, this tubule 23 inserts the inwall of described flexible pipe 4, the outer wall of described flexible pipe 4 is entangled in described bassoon 22, and described flexible pipe 4 front ends withstand on the front end sealing part of described large and small pipe 22,23.Hose coupling solves the sealing problem of dust collecting tube of dust collector.The buckle 11 at bend pipe 1 rear portion matches with the card button 31 on collar 3.Because collar 3 is inserted in flexible pipe 4, when collar 3 inserts bend pipe 1, card button 31 springs on collar 3 are first compressed; One be inserted on bend pipe 1 buckle 11 place the time, spring stretches, card button 31 is sprung in the buckle 11 on bend pipe 1, has solved flexible pipe 4 and the close-connected problem of bend pipe 1.
Described hose coupling 2 by good springiness, there is good toughness, rigidity, the HDPE high-density polyethylene plastics that cold-resistant, heat-resisting, wear-resisting, chemical stability is good is made.
