Abstract

A dust cup structure includes a cup body, an air inlet is provided on the side of the cup body, a cyclone cone is provided in the cup body, one end of the cyclone cone is connected to the top air outlet of the cup body, a filter cartridge is provided on the outer periphery of the cyclone cone, a cone tube is connected to the bottom end of the filter cartridge, the bottom end of the cone tube abuts against the bottom flip cover of the cup body, the bottom center of the flip cover is indented inward to form a ball socket structure, the inner side of the flip cover and the outer periphery of the ball socket structure form an annular groove corresponding to the bottom end of the cone tube, and a first sealing ring is embedded in the annular groove. This scheme achieves sealing of the cone tube by providing an inwardly concave ball socket structure at the center of the bottom side of the flip cover, and forming an annular groove corresponding to the bottom end of the cone tube on the outer periphery of the ball socket structure, and a first sealing ring is embedded in the annular groove to prevent dust from being sucked into the vacuum motor through the gap between the two; in addition, by providing a second sealing ring corresponding to the bottom opening of the cup body on the inner side of the flip cover, the sealing of the dust cup is improved, thereby avoiding the loss of suction force generated by the vacuum motor and ensuring the dust collection effect.

Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a dust cup structure. Background Art

[0002] Vacuum cleaners generally use cyclone separation to separate dirt from the airflow carrying dirt. A cyclone separator generally refers to a cylindrical cup body where the airflow enters from the side, and the high-speed airflow rotates along the inner wall of the cup body, and then large particles of garbage are thrown out into the dust storage chamber, and the airflow leaves the cup body or enters the next level of filtration structure through the filter screen.

[0003] The bottom of the ash storage chamber is usually provided with a flap structure for cleaning the dust in the ash storage chamber. Generally speaking, the bottom end of the cyclone cone and the flap are in a sealed contact state. However, during use, due to vibration, gaps are likely to appear between the flap and the cyclone cone; in addition, there are also gaps at the connection between the flap and the ash storage chamber; these gaps affect the vacuum effect of the vacuum cleaner, and dust may be sucked into the vacuum motor, affecting the service life.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to design a dust cup structure to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the utility model aims to provide a dust cup structure.

[0007] The preferred technical solution is: one side of the flip cover is hingedly connected to the cup body, and the other side of the flip cover is buckled and fixed to the cup body.

[0008] The preferred technical solution is: a skirt is provided on the outer circle of the connection between the cone tube and the filter cartridge.

[0009] The preferred technical solution is that the skirt is arranged to be inclined downward from the inside to the outside.

[0010] The preferred technical solution is: a second sealing ring corresponding to the bottom opening of the cup body is provided on the inner side of the flip cover.

[0011] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0012] The utility model provides a dust cup structure, which is provided with an inwardly recessed ball socket structure at the center of the bottom side of a flip cover, and an annular groove corresponding to the bottom end of a cone tube is formed on the outer periphery of the ball socket structure, and a first sealing ring is embedded in the annular groove to seal the cone tube and prevent dust from being sucked into the vacuum motor through the gap between the two.
