Detailed Description

to facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. 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.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In one embodiment of the present invention, as shown in figure 1, a cyclonic separating apparatus 100 is provided. The cyclonic separating apparatus 100 may be fitted to a vacuum cleaner for separating dirt and air entering it.

The cyclone separation apparatus 100 includes a main body 10 having a dust outlet 11, a cover 30 openably and closably disposed at the dust outlet 11, a sensing unit 50 for detecting whether the dust outlet 11 is closed by the cover 30, and a controller. The body 10 separates air and dust from the sucked air, collects the dust, and finally discharges the dust from the dust discharge port 11 when the dust is collected by a certain amount. Moreover, the dust exhaust port 11 is closed and opened by the cover body 30, and when dust exhaust is needed, the cover body 30 can be opened; after the dust exhaust is finished, the cover body 30 can be covered on the dust exhaust opening 11 to seal the dust exhaust opening 11.

when the sensing unit 50 detects that the dust exhaust port 11 is closed by the cover 30, the controller controls the dust collector to be in a working mode, at this time, the dust exhaust port 11 is closed, and when the dust collector works, outside air flow cannot flow backwards into the cyclone separation device 100 from the dust exhaust port 11. The controller also controls the dust collector to be in a shutdown mode when the sensing unit 50 detects that the dust exhaust port 11 is not closed by the cover 30; that is, if the sensing unit 50 detects that the dust discharge port 11 is not closed, the vacuum cleaner is in a shutdown mode, the cyclone separation apparatus 100 does not operate, and external air is prevented from being sucked into the cyclone separation apparatus 100 from the unclosed dust discharge port 11 (as shown in fig. 2), so that the cyclone separation apparatus 100 is protected, and the service life of the cyclone separation apparatus 100 is prolonged.

Alternatively, the controller switches the mode of the cleaner by controlling the on and off of a vacuum motor in the cleaner. Wherein a vacuum motor may be used to draw the airstream into the cyclonic separating apparatus 100. For example, when the controller controls the vacuum motor to be turned on, the external air enters the cyclone separation device 100 under the adsorption of the vacuum motor, and the cleaner is in a working mode; or when the controller controls the vacuum motor to be switched off, the outside air can not be adsorbed, can not enter the cyclone separation and assembly 100, and the dust collector is in a stop mode.

The body 10 includes a dirt cup 12 and a cyclonic separation assembly 14, the cyclonic separation assembly 14 being disposed within the dirt cup 12 for separating dirt and dust from air. After entering the dirt cup 12, the airflow is directed by the cyclonic separation assembly 14 to spiral down the axis of the dirt cup 12, causing dirt and dust in the air to be drawn closer to the inside wall of the dirt cup 12 by centrifugal force and to be deposited at the bottom of the dirt cup 12 by gravity. Meanwhile, another part of the airflow without dust in the downward spiral gradually gathers towards the axial center of the dust cup 12 and then is discharged out of the spiral wind power assembly, so that the clean air can be separated and discharged.

And, one end of the dust cup 12 is formed with a dust discharge port 11, and the cover 30 is rotatably provided on the dust cup 12 to close and open the dust discharge port 11. When the dust in the dust cup 12 needs to be cleaned, the cover 30 is rotated around the hinge point between the cover and the dust cup 12 in the direction away from the dust cup 12, the dust discharge opening 11 is opened, and the dust accumulated in the dust cup 12 is conveniently cleaned through the dust discharge opening 11. When the cyclone separating apparatus 100 needs to be operated, the cover 30 is pivoted around the hinge point with the dust cup 12 in a direction approaching the dust cup 12 to close the dust outlet 11.

As shown in fig. 3, the cyclone separating assembly 14 includes a primary cyclone cover 141, the primary cyclone cover 141 is disposed in the dirt cup 12, a primary cyclone flow channel 131 is formed between the primary cyclone cover 141 and an inner sidewall of one end of the dirt cup 12, and the dirt cup 12 is provided with an air inlet 121 communicated with the primary cyclone flow channel 131; a primary dust collecting chamber 133 communicating with the primary cyclone flow path 131 is formed between the primary cyclone cover 141, the inner wall of the other end of the dust cup 12, and the cover 30. The outside air flow enters the primary cyclone flow channel 131 from the air inlet 121, spirally descends in the primary cyclone flow channel 131, and the dust entrained in the rotating air flow is separated to the inner side wall of the dust cup 12 under the action of centrifugal force and enters the primary dust collection cavity 133 under the action of self gravity and descending air flow.

the cyclone separation assembly 14 further includes a secondary cyclone cover 143, and the secondary cyclone cover 143 is disposed downstream of the airflow in the primary cyclone cover 141, and is used for driving the airflow to perform secondary air-dust separation. That is, after the airflow passes through the primary cyclone flow channel 131 for the first air-dust separation, the airflow enters the secondary cyclone cover 143 again for the second air-dust separation, so as to improve the separation effect.

specifically, the secondary cyclone cover 143 has a secondary cyclone flow channel 151 and is sleeved in the primary cyclone cover 141, the secondary cyclone flow channel 151 is communicated with the primary cyclone flow channel 131, and a secondary dust collection chamber 153 communicated with the secondary cyclone flow channel 151 is formed between the secondary cyclone cover 143 and the cover 30. The airflow after primary separation enters the secondary cyclone flow channel 151 from the primary cyclone flow channel 131, then spirally descends in the secondary cyclone flow channel 151, and dust is beaten on the inner wall of the secondary cyclone hood 143 due to the centrifugal force in the spiral process and enters the secondary dust collection chamber 153 under the action of self gravity. Meanwhile, the cleaning airflow without containing dust is collected toward the center of the secondary cyclone flow passage 151, and is discharged out of the cyclone device 100 through the discharge port 123 after going upward.

further, the cyclone separation assembly 14 further includes a filter screen 145, the filter screen 145 is disposed on the primary cyclone cover 141, and the secondary cyclone flow channel 151 is communicated with the primary cyclone flow channel 131 through the filter screen 145. Thus, the air flow separated in the primary cyclone flow path 131 is filtered by the filter mesh 145 and then enters the secondary cyclone flow path 151 for secondary separation. Optionally, the filter screen 145 is detachably disposed on the primary cyclone cover 141, so as to facilitate cleaning.

as shown in fig. 1, the sensing unit 50 includes a sensing module 52 and a sensing switch 54, one of the sensing module 52 and the sensing switch 54 is disposed on the main body 10, and the other of the sensing module 52 and the sensing switch 54 is disposed on the cover 30 and moves with the cover 30 in a direction approaching to and moving away from the main body 10. When the sensing switch 54 is not acted by the sensing module 52 and is in the off state, it is described that the distance between the sensing module 52 and the sensing switch 54 is far, the cover 30 is far from the body 10, the dust exhaust port 11 is not closed, the controller controls the dust collector to be in the shutdown mode, the cyclone separation device 100 is prevented from being started when the dust exhaust port 11 is not closed, the airflow is prevented from flowing backwards into the secondary cyclone flow channel 151 to bring dust and being blocked by the filter screen 145, dust deposition on the filter screen 145 is reduced, the cleaning frequency of the filter screen 145 is reduced, and the service life of the cyclone separation device 100 is prolonged.

Further, when the sensing module acts on the sensing switch 54 to be in an open state, which means that the sensing module 52 is close to the sensing switch 54, the cover 30 covers the main body 10 to close the dust outlet 11, and at this time, the controller controls the vacuum cleaner to be in a working mode, so that the airflow is not allowed to flow backward from the dust outlet 11 during air suction.

Alternatively, the sensing module 52 is a magnet and the sensing switch 54 is a hall element or a reed switch. In an embodiment, the sensing module 52 is disposed at an end of the cover 30 away from a hinge point of the cover 30 and the body 10, the sensing switch 54 is disposed at an outer periphery of the dust exhaust port 11 of the body 10, and when the cover 30 closes the dust exhaust port 11, the sensing module 52 is close to the sensing switch 54 and triggers the sensing switch 54 to be turned on. Therefore, the controller can judge the opening and closing state of the dust exhaust port 11 according to the state of the inductive switch 54, and further judge whether the dust collector can start working, and only when the inductive switch 54 is opened and the dust exhaust port 11 is closed, the dust collector can enter a working mode.

In an embodiment of the present invention, there is also provided a vacuum cleaner including the cyclone separation apparatus 100, which has a long service life.

the technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
