Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a cleaning accessory and a cleaning appliance with an air inlet opening and closing device. Background Art

[0002] At present, there are two types of floor brush cleaning accessories on the market: large-particle floor brushes and dust removal floor brushes, which are used in different product usage scenarios. The difference between the two floor brushes lies in the change in the air intake opening area. Large-particle floor brushes can recover large particles of dirt because of their large air intake area, but because the air intake area is too large, the dust removal efficiency of the floor brush is generally not very high. For similar technologies, please refer to Chinese utility model patent CN208837816U. The dust removal floor brush has a small air intake opening area, and can achieve better dust removal capabilities when used, but the movement resistance and cleaning effect on large particles are very poor. For similar technologies, please refer to Chinese utility model patent CN201624604U. Therefore, in order to cope with the complex usage conditions of existing households, different floor brushes need to be equipped, which leads to increased costs.

[0029] The accessory seat 1000 is a roughly rectangular injection-molded part that can reciprocate on a plane to be cleaned, and its moving direction is perpendicular to the lateral direction of the accessory seat 1000 and parallel to the longitudinal direction of the accessory seat 1000. The central axis direction of the roller brush body 4000 is parallel to the lateral direction of the accessory seat 1000. The roller brush chamber 1200 is arranged near the front end of the accessory seat 1000, and a pair of rollers are arranged at the rear end of the accessory seat 1000 to assist in movement. The receiving member 1400 has a receiving groove 1420 for receiving the moving member 3400. A pair of rotating shaft holes 1620 are arranged on both sides of the accessory seat opening 1600. At the same time, the accessory seat opening 1600 includes an air inlet 1640 located at the bottom, and a plurality of fixing members 1660 located at the top and each having a perforation.

[0030] The accessory cover 2000 covers the accessory seat 1000 and is fixedly connected by screws. The accessory cover 2000 at least shields the top of the roller brush chamber 1200 and is a substantially rectangular injection molded part. The cover hole 2200 is arranged near the front end of the accessory seat 1000 and extends along the lateral direction of the accessory seat 1000.

[0031] The air inlet opening and closing device includes a sliding member 3000 having a sliding inclined surface 3020, a button member 3200 detachably connected to the sliding member 3000, a moving member 3400 driven by the sliding member 3000 at one end, and a rotating cover 3600 that abuts against the other end of the moving member 3400 and opens and closes the accessory seat opening 1600. The button member 3200 includes a button base 3220, a shift block 3240 disposed above the button base 3220 and in contact with the user's finger, and a pair of button claws 3260 disposed below the button base 3220 and fixedly connected to the sliding member 3000. The shift block 3240 is exposed in the cover plate hole 2200 and can reciprocate. There are multiple moving members 3400, and they include an inclined end 3420 at the top, a contact end 3440 at the bottom, and a track rib located at one side and reciprocating along the receiving groove 1420.
