Detailed Description
The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention.
Example one
The present embodiment provides a dust collecting assembly, which comprises a dust cup 11 and a dust scraping ring detachably disposed in the dust cup 11, as shown in fig. 1 to 10.
Compared with the prior art, the collection dirt subassembly that this embodiment provided, because scrape in the dirt cup 11 is located to the dirt ring detachable, when particulate matters such as dust were poured by the open end at dust cup 11 top in the dust cup 11, can take out in the dust cup 11 with scraping the dirt ring, reduce and avoid particulate matters such as dust to contact with scraping the dirt ring even to can guarantee the cleaning performance to dust cup 11, avoid particulate matters such as dust to remain in scraping dirt ring and/or dust cup 11.
Meanwhile, when the cleaning effect of the filter screen cover is reduced due to the fact that the dust scraping ring is used for too many times, the dust scraping ring can be separated from the dust collecting cup 11, and the dust scraping ring is convenient to replace.
The dust scraper ring is provided at the open end of the dust cup 11 in view of its dust scraping effect and the dust collecting space of the dust cup 11. Like this, in the removal in-process of dust cup 11 with filter screen panel, scrape the dirt ring and can basically pass through filter screen panel's whole outer wall face, guarantee the clearance effect to filter screen panel, in addition, will scrape the dirt ring and locate the open end of dust cup 11, the setting of scraping the dirt ring can not influence the collection dirt space of dust cup 11 basically to can guarantee the collection dirt effect of dust cup 11.
In view of space layout and force balance, the relative positions of the dust scraping ring and the dust collecting cup 11 have the following three conditions:
in a first situation, see figure 1, when the dust ring is in an assembled state with the dust cup 11, i.e. the dust ring is fully located within the dust cup 11, the axis a of the dust ring and the axis B of the dust cup 11 are parallel or coincide with each other.
In a second case, referring to Figs. 2 to 3, when the dust ring is separated from the dust cup 11, i.e. the dust ring is partially or entirely outside the dust cup 11 and is oriented differently from the dust cup 11, the axis A of the dust ring forms an angle of 90 DEG or more with respect to the axis B of the dust cup 11, so that when particles of dust, etc. in the dust cup 11 are poured out from the open end of the top of the dust cup 11, the path of movement of the particles of dust, etc. does not substantially pass through the dust ring, thereby reducing the contact of the particles of dust, etc. with the dust ring.
In order to further reduce the contact between the particles such as dust and the like and the dust scraping ring, the dust scraping ring is totally arranged outside the dust collecting cup 11, and the included angle between the axis A of the dust scraping ring and the axis B of the dust collecting cup 11 is larger than 90 degrees.
In a third situation, referring to fig. 4, when the dust ring is separated from the dust cup 11, i.e. the dust ring is completely outside the dust cup 11 and the dust ring and the dust cup 11 are oriented in the same direction, the axis a of the dust ring is parallel to the axis B of the dust cup 11, so that when particles such as dust in the dust cup 11 are poured out from the open end of the top of the dust cup 11, the movement path of the particles such as dust does not pass through the dust ring, thereby preventing the particles such as dust from contacting the dust ring.
To the structure of scraping the dirt ring, specifically, along the axial of scraping the dirt ring, it includes linkage segment 1 and scrapes dirt section 2 with linkage segment 1 detachable connection, scrapes dirt section 2 and passes through linkage segment 1 and dust cup 11 pivotal connection for scrape dirt section 2 and can wind linkage segment 1 and dust cup 11 junction upset, scrape the outer wall of dust collecting equipment's filter screen panel is located to dirt section 2 cover.
Considering that the dust scraping section 2 is mainly used for cleaning dust of a filter screen, and the connecting section 1 is mainly used for structural support, therefore, the dust scraping section 2 is an elastic member and made of a deformable material (such as rubber), the connecting section 1 is a rigid member, that is, the elastic modulus of the dust scraping section 2 is greater than that of the connecting section 1, and the mechanical strength of the dust scraping section 2 is less than that of the connecting section 1. Wherein, scrape dirt section 2 and can improve the area of contact who scrapes dirt section 2 and filter screen panel through elastic deformation for scrape dirt section 2 can with filter screen panel abundant contact, be convenient for it and carry out the deashing to filter screen panel, and rigid linkage segment 1 then can carry out the outrigger to scraping dirt section 2.
To achieve a pivotal connection between the attachment section 1 and the dust cup 11, the pivotal side of the attachment section 1 is pivotally connected to the dust cup 11 by a pivot member. Regarding the structure of the pivot member, specifically, it includes a rotating shaft 3 and a turnover plate 4 pivoted to the rotating shaft 3, the rotating shaft 3 is located outside the turnover plate 4, one of the pivot side of the connection section 1 and the dust cup 11 is connected to the turnover plate 4, and the other of the pivot side of the connection section 1 and the dust cup 11 is connected to the rotating shaft 3. In this way, pivoting between the pivoting side of the connecting piece 1 and the dust cup 11 of the dust collecting device is achieved by pivoting between the spindle 3 and the flipping panel 4.
Illustratively, the pivoting side of the attachment section 1 is connected to the flipping panel 4 and the dirt cup 11 is connected to the spindle 3.
In order to avoid the dust ring from wobbling relative to the dust cup 11, the non-pivoting side of the connecting section 1 (i.e. the side where no pivoting member is provided) may also be detachably connected to the dust cup 11 by means of a snap-in connection. As for the structure of the snap connection, in particular, it comprises a snap projection 5 (e.g. a snap) and a snap groove 6 cooperating with the snap projection 5, one of the non-pivoting side of the connecting section 1 and the dust cup 11 is provided with the snap projection 5 and the other of the non-pivoting side of the connecting section 1 and the dust cup 11 is provided with the snap groove 6.
Illustratively, the catch projection 5 is provided on the non-pivoting side of the attachment section 1 and the catch recess 6 is provided on the dirt cup 11.
Likewise, in order to realize the detachable connection of the connection section 1 and the dust scraping section 2, one of the connection section 1 and the dust scraping section 2 is provided with a connection projection 7, and the other of the connection section 1 and the dust scraping section 2 is provided with a connection groove 8, and the connection projection 7 is inserted into the connection groove 8. When the dust scraping section 2 needs to be replaced, the connecting protrusion 7 and the connecting groove 8 can be separated, so that the detachable connection between the connecting section 1 and the dust scraping section 2 is realized.
Exemplarily, the connecting protrusion 7 is arranged on the inner wall surface of the dust scraping section 2, and the connecting groove 8 is arranged on the outer wall surface of the connecting section 1, that is, the dust scraping section 2 is sleeved outside the connecting section 1; or, the connecting protrusion 7 is disposed on the outer wall surface of the dust scraping section 2, and the connecting groove 8 is disposed on the inner wall surface of the connecting section 1, that is, the dust scraping section 2 is sleeved on the inner side of the connecting section 1.
It should be noted that, in order to increase the dust scraping area of the dust scraping section 2, the connecting protrusion 7 is provided at one of the end of the connecting section 1 facing the dust scraping section 2 and the end of the dust scraping section 2 facing the connecting section 1, and the connecting groove 8 is provided at the other of the end of the connecting section 1 facing the dust scraping section 2 and the end of the dust scraping section 2 facing the connecting section 1.
