Example 1

Referring to fig. 1 and 2, the present invention provides a dust bag fixing structure, which includes a fixing plate 1, a fixing cylinder 2 for opening an opening of a dust bag is disposed on one side of the fixing plate 1, a through dust collecting channel is disposed on the fixing cylinder 2, and a fixing clip 3 for clamping or loosening the dust bag is mounted on the fixing plate 1.

Specifically, this fixed consumption type dirt bag of dirt bag fixed knot of structure adaptation centre gripping, the fixed cylinder 2 of taking the collection dirt passageway is used for strutting the opening of dirt bag, then relies on fixation clamp 3 of installation itself on fixed plate 1 to stabilize centre gripping dirt bag, breaks off fixation clamp 3 with the fingers and thumb after the dirt is full and makes the dirt bag drop, compares in prior art with the dirt bag opening according to pressing on the mounting outer wall, the utility model discloses a fixed effect of structural design is better, can prevent that dust catcher suction from breaking away when big.

As a design form of one of the fixing clips 3, the fixing clip 3 includes a first clip body 3a and a second clip body 3b, two first clamping pieces 3c are arranged on the first clip body 3a at intervals, and two second clamping pieces 3d which are respectively arranged opposite to the first clamping pieces 3c and used for matching and clamping a dust bag are arranged on the second clip body 3 b. The pair of first clamping pieces 3c and the second clamping pieces 3d form a first clamping point for the dust bag, the other pair of first clamping pieces 3c and the second clamping pieces 3d form a second clamping point for the dust bag, and the dust bag can be fixed more stably through two-point clamping.

Preferably, in order to improve the clamping effect of the fixing clip 3, the inner sides of the first clamping piece 3c and the second clamping piece 3d may be respectively provided with mutually staggered clamping teeth 3 e.

Preferably, in order to prevent the dust in the dust bag from reversely leaking out of the dust collecting passage, in this embodiment, the dust bag fixing structure further includes a dust blocking sheet 4 installed in the dust collecting passage for one-way dust blocking. Specifically, an annular limiting step 5 may be provided on the inner wall of the fixed cylinder 2, one end of the dust guard sheet 4 is fixed on the annular limiting step 5, and the edge portion of the dust guard sheet 4 is placed on the annular limiting step 5. Preferably, the dust blocking sheet 4 is provided with a bending groove 6 on one side departing from the annular limiting step 5, the bending groove 6 is arranged close to a fixed point of the dust blocking sheet 4 on the annular limiting step 5, and the design of the bending groove 6 can enable the whole dust blocking sheet 4 to be more easily bent inwards when facing the wind, so that the middle dust collecting channel is quickly exposed.

Preferably, the end of the fixing cylinder 2 far away from the fixing plate 1 is provided with an insertion piece 2a for quickly inserting into an opening of the dust bag, the end of the insertion piece 2a is relatively sharp, so that a user can conveniently and quickly insert into the opening of the dust bag, and the dust bag can be conveniently and quickly assembled and fixed.

Example 2

In this embodiment, one of the optimized designs is made based on the embodiment 1, please refer to fig. 3 to 5, in which the upper ends of the two first clamping pieces 3c are connected through the toggle block 7, the first clamping piece 3c and the second clamping piece 3d are released when the toggle block 7 is pressed, and the first clamping piece 3c and the first clamping piece 3d are clamped when the toggle block 7 is released.

In this kind of design, the user can press first clamping piece 3c with one hand for thereby fixation clamp 3 opens and releases the dirt bag that gathers dust, and the one-hand operation of user is convenient for during practical application, and the dirt is kept away from as far as possible when pouring the dirt.

Example 3

In this embodiment, one of the optimized designs is made on the basis of the above embodiment 1, a limiting block 9 for limiting the movable region of the fixing clip 3 is arranged on the fixing plate 1, and the first clip body 3a and the second clip body 3b are movably connected through an elastic member; when at least one of the clamp bodies is pressed, the first clamping piece 3c and the second clamping piece 3d are loosened, and when the first clamp body 3a or the second clamp body 3b is loosened, the first clamping piece 3c and the second clamping piece 3d are clamped. In this embodiment, pass through the elastic component with two clamp bodies of fixation clamp 3 and connect to carry on spacingly through stopper 9, make fixation clamp 3 press from both sides tightly each other two clamping pieces under the normal state, when pressing down the clamp body and making the elastic component shorten, fixation clamp 3 opens and makes the pine of disposable dirt bag take off.

There are two kinds of design forms here, stopper 9 can design a plurality ofly, the first: first clamp 3a, second clamp 3b are both the activity and set up on fixed plate 1 to carry on spacingly by the stopper 9 that corresponds, when pressing two clamps (or the relative pressing piece that sets up on two clamps), the elastic component shortens first clamping piece 3c and second clamping piece 3d and keeps away from, makes fixation clamp 3 loosen, and when loosening two clamps under the normality, first clamping piece 3c and second clamping piece 3d are close to each other and press from both sides tight disposable dust bag.

And the second method comprises the following steps: one of the first clip body 3a and the second clip body 3b is fixed on the fixing plate 1, and the other is movably limited by the limiting block 9, as shown in fig. 6 and 7, which is an example, the second clip body 3b is fixed on the fixing plate 1, the first clip body 3a is limited by the limiting block 9 and can slide linearly, the first clip body 3a and the second clip body 3b are connected by the spring 8 and keep a distance, when the first clip body 3a (or the pressing piece arranged on the first clip body 3a) is pressed, the spring 8 shortens the distance between the first clip piece 3c and the second clip piece 3d, the fixing clip 3 is released to make the dust bag fall off, otherwise, when the first clip body 3a is released, the two clip pieces are close to each other to clamp the dust bag.

In this kind of design, two clamping pieces can press from both sides tight dirt bag under the spring action, and when the collection was full of the dust, the user then can the one-hand operation press the clamping piece for two clamping pieces keep away from each other and loosen the dirt bag, can make the human body keep away from the dirt bag of raise dust as far as possible when falling dirt like this, convenient health more.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
