Embodiment Construction
[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0029] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a dust collector, a dust cup device and a separation cone thereof. The separation cone comprises a separation cone body which is provided with an inner cavity, and an air inlet, an air outlet and a dust collection port that are in connection with the inner cavity; the air inlet is located in the circumferential side wall of the top end of the separation cone. The air outlet and the dust collection port are located in the axial top end and bottom end of the separation cone respectively; an dust discharging branch is included, an inlet of the dust discharging branch iscommunicated with the top end of the inner cavity, and an outlet of the dust discharging branch is communicated with the bottom end of the inner cavity. By setting the dust discharging branch, airflowin an emptying area at the top end of the inner cavity of the separation cone body can enter the dust discharging branch from the inlet of the dust discharging branch, and dust is discharged from theoutlet of the dust discharging branch to the bottom end of the inner cavity of the separation cone body; dust and dirt collide with the circumferential side wall of the inner cavity of the separationcone under the action of centrifugal force, so that the dust and the dirt fall into a gas collection port to be collected, dust-gas separation is realized, formation of an upper ash ring is avoided,the dust-gas separation effect is improved, and reduction of the influence on the service life of a motor and the environment is facilitated.
Description
technical field [0001] The invention relates to the technical field of dust collection equipment, in particular to a vacuum cleaner, a dust cup device and a separating cone. Background technique [0002] With the continuous improvement of people's living standards, the requirements for residential sanitation and environmental sanitation are also getting higher and higher. Vacuum cleaners have gradually become an indispensable household appliance in life. [0003] Generally, the vacuum cleaner has a dust cup device for multi-layer filtration and separation of gas and dust. The gas and dust entering the dust cup device are separated by cyclone, the dust is collected in the dust collection chamber, and the gas is discharged. However, the dust cup device in the prior art cannot separate part of the dust with small particle size, and it will be discharged with the air flow, affecting the service life of the motor and causing pollution to the environment.
