Fig. 1 to 3 show a cyclonic separating apparatus provided in accordance with a first embodiment of the present application, comprising a cyclonic separator and a dirt cup 20.

The cyclone separator is provided with an air inlet 33 and an air outlet 36, the air inlet 33 is used for air flow inflow, and the air flow separated by the cyclone separator is discharged through the air outlet 36. In an embodiment, the air inlet 33 may be directly connected to the outside, or may be connected to the outside through an intermediate component, which is not limited herein.

Further, the cyclone separator includes a shielding case 30 and a filtering member 40, a dust-air separation bin 32 is formed between the shielding case 30 and the filtering member 40, the airflow swirls in the dust-air separation bin 32 and is filtered and separated by the filtering member 40, and a dust outlet 320 for discharging dust from the dust-air separation bin 32 is formed at a lower end of the dust-air separation bin 32. The air inlet 33 is positioned at the upper part of the cyclone separator, the airflow enters the dust-air separation bin 32 from the air inlet 33 positioned at the upper part and flows in a cyclone shape in the dust-air separation bin 32, the flowing direction of the airflow is approximately tangent to the circumferential surface of the filter piece 40, and therefore dirt or dirt carried in the airflow is not prone to blocking the filter piece 40.

Specifically, the isolation cover 30 is at least partially covered on the circumferential direction of the filter element 40, and an annular airflow gap, i.e., the dust-gas separation bin 32, is formed between the isolation cover 30 and the filter element 40.

A dirt cup 20 is connected to the cyclone separator for collecting the filtered dirt. The dust cup 20 comprises a dust collecting cavity 25 for containing dust, the dust collecting cavity 25 is communicated with the dust-air separation bin 32 through the dust outlet 320, and the dirt is discharged into the dust collecting cavity 25 of the dust cup 20 through the dust outlet 320 under the action of gravity through the cyclone separation action of the filter element 40 and the dust-air separation bin 32.

The cyclone separation device provided by the embodiment is characterized in that the isolation cover 30 is arranged outside the filter piece 40, so that the relatively independent dust-air separation bin 32 is formed between the isolation cover 30 and the filter piece 40, the cyclone is conveniently formed in the circumferential direction of the filter piece 40, the cyclone separation effect is good, and dirt is not prone to blocking the filter piece 40. Furthermore, the dust outlet 320 arranged at the lower end of the dust-gas separation bin 32 is communicated with the dust cup 20, residual dirt after filtration is discharged into the dust collection cavity 25 of the dust cup 20 through the dust outlet 320, the dust-gas separation bin 32 is relatively independent from the dust collection cavity 25 and is communicated only through the dust outlet 320, the possibility that the dirt stored in the dust collection cavity 25 is rolled up again by cyclone is reduced, and the risk of secondary pollution on the filter element 40 is reduced.

In this embodiment, the cyclone separator further includes a cover 26, the filter member 40 is attached to the cover 26, and the cover 26 facilitates removal of the filter member 40 from the cyclone separator and cleaning of the filter member 40.

In order to reduce the effect of the cyclonic airflow in the dust and air separation chamber 32 on the dirt in the dust collection chamber 25. In one embodiment, the shielding cage 30 includes a sidewall 321 surrounding the filter element 40, the sidewall 321 at least partially circumferentially separating the dust collection chamber 25 from the dust-gas separation bin 32.

The airflow carrying dirt flows in from the upper part of the cyclone separator and spirals downwards under the action of gravity, the dirt moves downwards along with the airflow, and in order to facilitate the dirt to fall into the dust collecting cavity 25, the dust outlet 320 is arranged at the bottom of the side wall 321 of the isolation hood 30. Moreover, the dust outlet 320 is disposed on the sidewall 321, the dust outlet 320 is not disposed opposite to the dust collecting chamber 25, and even if the dirt in the dust collecting chamber 25 is rolled up, the dirt is not easy to enter the dust-air separating compartment 32 again through the dust outlet 320.

Specifically, the isolation cover 30 includes a first portion having the air inlet 33 and a second portion having the dust outlet 320, and the outer diameter of the first portion is larger than that of the second portion. The first part is hermetically connected with the dust cup 20, and the second part extends into the dust cup 20, so that the dust outlet 320 arranged on the second part extends into the dust collection cavity 25, and dust is directly discharged to the deep part of the dust collection cavity; at the same time, the second portion has a circumferential gap with the sidewall of the dirt cup 20, which facilitates cyclonic flow.

Preferably, the shielding case 30 is provided with a bottom wall 322 at the bottom of the dust-gas separation bin 32, and the bottom wall 322 separates the dust-gas separation bin 32 from the dust collecting cavity 25 in the axial direction, so as to reduce the influence of the airflow in the dust-gas separation bin on the airflow in the dust collecting cavity 25.

Referring to fig. 2, the dust cup 20 is sleeved outside the cyclone separator, at least partially houses the cyclone separator, and an opening 23 is formed at a position corresponding to the air inlet 33 to communicate with the outside, so that the airflow enters the air inlet 33 from the opening 23 of the dust cup 20 and is finally discharged from the air outlet 36. The cyclone separator further comprises a filter element 50 for further filtering the air flow, and the filter element 50 is used for filtering dust in the air flow, so that the cleanness of the air flow discharged outside is ensured, and the pollution to the outside air is prevented.

In another embodiment, the dust cup 20 may also be sleeved at the lower end of the isolation cover 30 and located below the air inlet 33, that is, the dust cup 20 does not envelop the air inlet 33, and the air inlet 33 may directly communicate with the outside.

It will be appreciated that the cyclonic airflow in the dust and air separating compartment 32 inevitably agitates the airflow in the dust collecting chamber 25 through the dust outlet 320, causing a cyclone to be created in the dust collecting chamber 25, the dirt entrained airflow spiraling upwards and stopping upwards by hitting the lower end face of the cyclone separator, and part of the dust falling back into the dust collecting chamber under the action of gravity, and part of the dirt possibly adhering to the lower end face.

In an embodiment, the cage 30 includes an inclined surface 341 arranged to face the dust collecting chamber 25 and inclined from the edge to the center. Specifically, the insulating cover 30 includes an inclined portion 34 forming the inclined surface 341, and the upper end of the inclined portion 34 is fixedly mounted on the first portion and the lower end is connected to the peripheral wall of the second portion. The inclined surface 341 is located at the top of the dust collection chamber 25, the air flow is slowly upward under the guiding action of the inclined surface 341 in the process of the upward spiral air flow, the wind power is gradually reduced, and the wind power is reduced to the lowest point when the highest point of the inclined surface 341 is reached, so that the dirt gradually falls back into the dust collection chamber 25 under the action of gravity in the process of the gradual reduction of the cyclone air flow. On the contrary, if the lower end surface of the cyclone separator is a plane, i.e. the top wall of the dust collecting chamber 25 is a flat top, the air flow meets the flat top in the spiral ascending process, the air flow continues to be upwards and then stops, and the impact occurs at the contact surface to generate unfavorable noise. Moreover, the cessation of the ascending air flow causes the dirt having an ascending tendency to adhere to the lower end surface of the cyclone, resulting in greater air flow resistance and contamination of the cyclone. In this embodiment, due to the transitional guiding action of the inclined surface 341, the spiral airflow does not end when encountering the top wall, but gradually and slowly reduces the flow velocity, so that when the flow velocity is lower than a certain range, the entrained dirt gradually falls back into the dust collection chamber 25 under the action of gravity, the spiral upward airflow continuously rises for a section on the surface of the inclined surface 341, and does not collide with the inclined surface 341 under excitation, so that the noise is low, and the dirt is not adhered to the inclined surface 341, thereby facilitating the cleaning of the cyclone separator.

The filter element 40 is for filtering large particle contaminants in the air flow and comprises filter mesh openings for filtering contaminants which may adhere to the filter element 40 during passage through the filter element 40, and in order to reduce the risk of clogging of the filter element 40 due to contaminants, the filter mesh openings are arranged in the side wall of the filter element 40, so that the contaminants are substantially blocked in the tangential direction of the filter element 40, facilitating the removal of the contaminants.

Further, the bottom end of the dust outlet 320 is lower than the bottom ends of the filter mesh holes, so that the dirt blocked by the filter mesh holes can fall into the dust collection cavity 25 through the dust outlet 320 under the action of gravity.

Fig. 4 and 5 show a cyclone separator of a cyclone separating apparatus of another embodiment provided in the present application, in which the cyclone separating apparatus in this embodiment has substantially the same structure as that of the cyclone separating apparatus of any of the above embodiments, the difference is only in the structure of the cyclone separating apparatus, for the sake of brevity, the same structure is given the same reference numerals, and no further description is given, and only different parts of the structure are described below.

Referring to fig. 4 and 5, the cyclone separator is different from any of the above embodiments in that the dust outlet 320' is formed at a different position. In this embodiment, the cyclone separator comprises a shroud 30 'and a filter member (not shown) disposed within the shroud 30', with a dust-gas separation bin 32 'formed between the shroud 30' and the filter member. Specifically, the cyclone includes a filter support 41 for mounting a filter member, the filter member being disposed on the filter support 41, the filter support 41 extending axially.

The dust outlet 320 ' is opened on the bottom wall of the isolation hood 30 ' and is located right below the dust-gas separation bin 32 '. Therefore, the dirt separated by the filter element is conveniently discharged to the dust collection cavity through the dust outlet 320' at the lower part under the action of gravity. Specifically, the filtering member is circumferentially spaced from the bottom of the shielding case 30 'to form a dust outlet 320' for discharging the dirt into the dust collecting chamber. Preferably, the lowermost end of the filter element does not extend beyond the bottom of the side wall of the cage 30' after the filter element has been assembled to the filter element support 41. In this way, the filter member is circumferentially spaced from the dust collecting chamber, reducing the interaction between the cyclone airflow in the dust-gas separation bin 32' and the airflow in the dust collecting chamber.

The present application also provides a cleaning appliance comprising a cyclonic separating apparatus as claimed in any one of the embodiments above.

To sum up, this application provides a cyclone and adopts this cyclone's cleaning equipment, through forming dirt gas separation storehouse filtering a piece dusty gas shield, the whirlwind air current in the dirt gas separation storehouse should not cause and filters stifled net.

The above description is only for the purpose of illustrating embodiments of the present invention and is not intended to limit the scope of the present invention, and all modifications, equivalents, and equivalent structures or equivalent processes that can be used directly or indirectly in other related fields of technology shall be encompassed by the present invention.
