Description
The utility model relates to dust catcher, especially refers to a kind of noise reduction and water-tight device of dust catcher air outlet.
Have the Wet-dry dust catcher now as shown in Figure 5: its air outlet B is located at cover cap C upper end one side, is an open pore.Because of being not full-time use, easily be the foreign object intrusion, comprise that cockroach, soup or children play and lose into foreign object etc., cause the dust catcher A time spent to break down or reduce service life.And air outlet B does not have any blocking, and can make a noise during air-out, influences people's sense of hearing.
The purpose of this utility model is to provide a kind of noise reduction and water-tight device of dust catcher air outlet.
The purpose of this utility model is achieved in that the noise reduction and the water-tight device of dust catcher air outlet, it comprises a block set, a body, it is characterized in that: block set is overcoat and slides over the concentric bilayer cylinder that the lower end links into an integrated entity with base plate, this double-layered cylinder comprises skin and internal layer, the outer overcoat that is incorporated into and protrudes dust catcher cover cap upper end air outlet for the upper end, internal layer sliding sleeve upper end inner edge has and goes up tiltedly flat annular inward flange down; The pipe of one section lower ending opening of Men Tiwei, tube wall bottom outer rim, be provided with the annular external flange of flat declivity, door body bottom tube wall, be provided with the upwardly extending pod from the lower end, there is the consubstantiality top cover that covers the overcoat upper end open tube wall upper end, and it is protruding that the top cover upper limb is provided with arc, around the top cover tube wall, be provided with symmetrical exhaust outlet.
Above-mentioned design, it is some that overcoat protrudes the cover cap upper limb, flows into along the overcoat ora terminalis in order to liquid or the water that prevents the cover cap upper limb; Hook jail door body when the annular inward flange of internal layer sliding sleeve is used to use prevents that the body from deviating from; The annular external flange of door body is in order to the annular inward flange in hook jail; Door body bottom tube wall is established many pods, dwindles in order to the elasticity of mat tube wall own and clamp-ons reinstatement in the sliding sleeve; Top cover is used to the outer set upper side of Mi Gai at ordinary times, prevents that foreign object from immersing; Arc on the top cover is protruding, stops in order to prevent liquid or water; Many to exhaust outlet under the top cover are released the door body by blast when being used to use, and wind is evenly got rid of continuously, and above-mentioned in a word design is comparatively careful, can satisfy instructions for use fully, and effect is obvious.
Be described further again below by drawings and Examples.
Fig. 1 the utility model is incorporated on the dust catcher, broken section and decomposing schematic representation;
Fig. 2 the utility model assembled state vertical section schematic diagram;
Fig. 3 the utility model door body is clamp-oned the sliding sleeve schematic diagram;
Fig. 4 the utility model assembled state schematic cross section;
Fig. 5 has dust catcher air outlet structure schematic diagram now.
Shown in Fig. 1-2: in the air outlet 3 of dust catcher 1, cover cap 2, if noise reduction and water-tight device 4, noise reduction and water-tight device 4 are made of block set 5, door body 6 and noise reduction net 7, the concentric bilayer cylinder that block set 5 links into an integrated entity with base plate 10 in the lower end for overcoat 8 and sliding sleeve 9, overcoat 8 upper ends are incorporated in the cover cap 2 upper end air outlets 3, and it is some to protrude cover cap 2 upper limbs, and the base plate 10 that overcoat 8 links to each other with sliding sleeve 9 is provided with a plurality of exhaust vents that run through 11, with exhaust outlet 12 air drafts simultaneously.Sliding sleeve 9 upper end inner edges are provided with oblique 13 times flat 14 annular inward flange 15.
Shown in Fig. 3,4: consult Fig. 1,2, door body 6 is the pipe of one section lower ending opening, tube wall bottom outer rim, be provided with annular external flange 18 flat 16, declivity 17, door body 6 bottom tube walls are provided with many pods 19, the upper end is provided with the consubstantiality top cover 20 that can cover overcoat 8 upper end open, and top cover 20 upper limbs have suitable arc protruding 21.Exhaust outlet 12 is two pairs and is symmetrical arranged, and its air draft reaction force supports raw silk mutually and becomes balance, so a body 6 reason blast and crooked not.Block set 5 bottoms are combined with a noise reduction net 7, in order to reduce the air draft noise.It is some that block set 5 is higher than cover cap 2, and small reptile also is difficult to invade.
