Abstract
The utility model relates to parts of a vacuum cleaner, in particular to an inlet air interface leak tight structure of the vacuum cleaner. The inlet air interface leak tight structure comprises an upper cover and an inlet air receiving tube which are made of ABS (acrylonitrile butadiene styrene) or PP (propene polymer) materials and is characterized in that the lower surface of an air inlet of the upper cover protrudes downwardly to form an edge sealing, the upper edge of the inlet air receiving tube folds outwardly to form a circular outwards turned edge which is in interference fit with the edge sealing to have the inlet air receiving tube assembled on the upper cover. The inlet air interface leak tight structure of the vacuum cleaner has the advantages that the upper cover and the inlet air receiving tube are assembled together through the interference fit of the outwards turned edge and the edge sealing, a further sealing ring is not required, so that the inlet air interface leak tight structure is simplified, cost is saved and assembling is facilitated; since the upper cover and the inlet air receiving tube are made of the ABS or PP materials, the outwards turned edge and the edge sealing are provided with certain elasticity, and the inlet air receiving tube is inserted into the upper cover to be tightly combined to guarantee good leak tightness which is capable of bearing the vacuum degree of -30KPa.
Description
Technical field
The utility model relates to a kind of parts of dust catcher, specifically a kind of air intake sealing joint structure of dust catcher.
Background technology
Dust catcher is widely used in family and the office's hygienic cleaning as the household electrical appliance of a kind of convenience, practicality.
Now the dust catcher performance demands is improved constantly, how to improve the service life of operational reliability, prolongation dust catcher, how to reduce the energy loss of dust catcher, become researcher's main research topic; The sealing of dust catcher air intake interface directly has influence on pick-up performance, energy loss and the service life of dust catcher, therefore, air intake sealing joint structure is improved, and can well address the above problem.
The air intake interface of existing dust catcher adopts more and sealing ring is set between loam cake and air intake interface realizes sealing, but sealing ring mostly is the rubber material, can produce the season cracking phenomenon after having grown service time, lose sealing function gradually, thereby influence operating efficiency and the service life of dust catcher, if use the sealing ring of other materials then can increase cost; During installation, sealing ring is not set level or installs not in place, all can influence its sealing effectiveness, and at above-mentioned shortcoming, its structure is still waiting further improvement.
Summary of the invention
The purpose of the utility model is to remedy above-mentioned deficiency, to society disclose a kind of simple in structure, easy for installation, cost is low, the air intake sealing joint structure of the dust catcher of good sealing effect.
The technical solution of the utility model is achieved in that
A kind of air intake sealing joint structure of dust catcher, comprise loam cake and the air intake adapter of being made by ABS or PP material, it is characterized in that: the edge sealing that the downward protrusion-shaped of the lower surface of the air inlet of described loam cake circularizes, the upper edge that described air intake is taken over outwards turns down the flange that forms annular, and described flange and described edge sealing interference fit and the air intake adapter is installed on covers.
The measure of taking for the optimization technique scheme also comprises:
Described flange upper edge is close to mutually with the lower surface of the air inlet of loam cake.
The diameter of described edge sealing is greater than the diameter of the air inlet of loam cake.The utility model advantage compared with prior art is:
The air intake sealing joint structure of dust catcher of the present utility model, the interference fit that its loam cake and air intake are taken over by flange and edge sealing directly is assembled together, and need not to arrange sealing ring between the two again, and structure is become simply, has also saved cost;
During installation, only need directly air intake to be taken in the edge sealing that inserts loam cake to get final product, very convenient, because loam cake and air intake are taken over and are ABS or the PP material is made, edge sealing and flange all have certain elasticity, air intake take over to insert behind the loam cake will be tightly in conjunction with to guarantee its good sealing property, can bear-vacuum of 30KPa.
Description of drawings
Fig. 1 is the exploded view of the utility model embodiment;
Fig. 2 is the structural representation (analysing and observe) of the utility model embodiment;
Fig. 3 is A portion enlarged drawing among Fig. 2.
The specific embodiment
The title of each Reference numeral is in the utility model accompanying drawing:
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is extremely shown in Figure 3,
The air intake sealing joint structure of a kind of dust catcher of the present utility model, comprise loam cake 1 and the air intake adapter 2 of being made by ABS or PP material, it is characterized in that: the edge sealing 12 that the downward protrusion-shaped of lower surface of the air inlet 11 of described loam cake 1 circularizes, the upper edge of described air intake adapter 2 outwards turns down the flange 21 that forms annular, and described flange 21 is taken over 2 with described edge sealing 12 interference fit with air intake and is installed on the loam cake 1.
Described flange 11 upper edges are close to mutually with the lower surface of the air inlet 11 of loam cake 1.
The diameter of described edge sealing 12 is greater than the diameter of the air inlet 11 of loam cake 1.
The air intake sealing joint structure of dust catcher of the present utility model, the edge sealing 12 that circularizes in the downward protrusion-shaped of lower surface of the air inlet 11 of loam cake 1, and take over 2 upper edge at air intake and outwards turn down the flange 21 that forms annular, replace existing ring structure to play sealing function by flange 21 and edge sealing 12 interference fit, because loam cake 1 and air intake are taken over 2 and are ABS or the PP material is made, edge sealing 12 and flange 21 all have certain elasticity, when loam cake 1 and air intake adapter 2 are assembled together, both fit tightly to guarantee its good sealing property, it can bear-vacuum of 30KPa, and simple in structure, cost is low, good sealing effect; During installation, only need directly air intake to be taken over 2 and insert in the edge sealing 12 of loam cakes 1 and get final product, installs very conveniently, air intake is taken over 2 be inserted into the end, flange 11 upper edges and the lower surface of the air inlet 11 of loam cake 1 are close to mutually, installation like this is more firm, and sealing property is better.
