Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A dirt cup cleaning assembly 100 in accordance with an embodiment of the first aspect of the present invention is described below with reference to fig. 1-6.
As shown in fig. 3, a dirt cup cleaning assembly 100 according to an embodiment of the first aspect of the present invention includes: a dust cup 1, a cyclone filter screen 2 and a scraper 3.
Specifically, the dust cup 1 is provided with a through hole, for example, the peripheral wall of the dust cup 1 may be provided with a through hole. The cyclone filter 2 is disposed in the dust cup 1, for example, the cyclone filter 2 is cylindrical extending along the first axis a, and the cyclone filter 2 is rotatably disposed in the dust cup 1 around the first axis a.
The scraper 3 is movable between a first position (for example, the position of the scraper 3 shown in fig. 3) and a second position (for example, the position of the scraper 3 shown in fig. 6), when the scraper 3 is at the first position, as shown in fig. 3, at least part of the scraper 3 passes through the through hole and abuts against the peripheral wall of the cyclone filter 2; when the scraper 3 is at the second position, the scraper 3 is separated from the cyclone filter 2. That is, the scraper 3 is movable between a first position abutting against the cyclone filter 2 and a second position separated from the cyclone filter 2, and the scraper 3 penetrates through the through hole to extend into the dust cup 1 at the first position.
Further, when the scraper 3 abuts against the peripheral wall of the cyclone filter 2 at the first position, the cyclone filter 2 and the scraper 3 can move relatively, and here, the relative movement of the cyclone filter 2 and the scraper 3 can be relative movement or relative rotation, or can be both relative movement and relative rotation. For example, in a specific example, the cyclone filter 2 and the scraper 3 are relatively rotatable in the circumferential direction of the cyclone filter 2, specifically, the cyclone filter 2 is rotatable around the first axis a, and the scraper 3 is fixed, at this time, the scraper 3 and the cyclone filter 2 can be relatively rotatable in the circumferential direction thereof; or, the cyclone filter screen 2 is fixed, the scraper 3 can rotate around the central axis (first axis a) of the cyclone filter screen 2, and at the moment, the scraper 3 and the cyclone filter screen 2 can also realize relative rotation in the circumferential direction; or, the cyclone 2 is rotatable around the first axis a, and the scraper 3 is also rotatable around the first axis a, in which case the scraper 3 and the cyclone 2 are also rotatable relative to each other in the circumferential direction thereof.
The operation of the dirt cup cleaning assembly 100 of this embodiment will be described by taking the example that the scraper 3 is fixed and the cyclone filter 2 is rotatable about the first axis a only when the scraper 3 is in the first position. After reading the following technical solutions, it is obvious to those skilled in the art that when the cyclone filter screen is fixed and the scraper is rotatable, the cyclone filter screen and the scraper are both rotatable, and thus detailed description thereof is omitted.

When the scraper 3 is in the first position, the seal portion 311 located at one end of the scraper body 31 in the circumferential direction (e.g., the left end of the scraper body 31 shown in fig. 3) abuts the cyclone filter 2; when the scraper 3 is at the second position, the free end surface of the sealing part 311 is flush with the inner wall surface of the dust cup 1, and the sealing part 311 seals the through hole on the dust cup.
When the dust cup 1 of the dust collector collects dust, the dust falls to the bottom of the dust cup 1 by rotating in the dust cup 1, but some of the dust or hairs may be adsorbed on the cyclone filter 2 while rotating around the cyclone filter 2. When hair and dust on the cyclone filter screen 2 need to be cleaned, the knob 51 can be rotated firstly, the knob 51 drives the scraper 3 to rotate from the second position to the first position sequentially through the second transmission rod 54, the first transmission rod 52 and the third gear 53, the scraper 3 is abutted against the outer peripheral wall of the cyclone filter screen 2, then the pull rod 41 is pulled along the length direction of the pull rod 41, the pull rod 41 drives the cyclone filter screen 2 to rotate sequentially through the first gear 42 and the second gear 43, and the cyclone filter screen 2 is in movable contact with the scraper 3, so that hair or dust on the cyclone filter screen 2 can be hung by the scraper 3. After the clearance, can the reverse rotation knob 51, rotate to the second position by the first position through second drive mechanism drive scraper blade 3 is reverse, at this moment, the through-hole on the dirt cup 1 can be sealed to the sealing portion 311 on the scraper blade 3, and the free end terminal surface of scraper blade 3 and the internal face parallel and level of dirt cup 1, that is to say, when not clearing up whirlwind filter screen 2, scraper blade 3 can not stretch into the inside of dirt cup 1 to can not influence the inside whirlwind system of dirt cup 1.
According to the dust cup cleaning assembly 100 provided by the embodiment of the invention, the scraper 3 on the side wall of the dust cup 1 can stretch, when dust is normally sucked into the dust cup 1, the scraper 3 is contracted, the cyclone structure in the dust cup 1 cannot be influenced, and meanwhile, the free end of the scraper 3 is provided with soft rubber which can be sealed with the side wall of the dust cup 1; when the scraper 3 is required to extend out, the scraper can be tangent to the cyclone filter screen 2, and the cyclone filter screen can be cleaned. According to the dust cup cleaning assembly 100 provided by the embodiment of the invention, dust and hair adhered to the cyclone filter screen 2 can be cleaned off without disassembling the dust cup 1, so that the cleaning by a user is facilitated, and the suction force of the dust collector is improved.
