Description

A dust collecting chamber and a vacuum cleaner

technical field

The invention relates to the field of living appliances, in particular to a dust collection room and a vacuum cleaner.

Background technique

The air-dust separation effect of a vacuum cleaner and the replacement and cleaning frequency of the air filter are the key indicators for evaluating its performance. The existing cyclone-separated vacuum cleaner includes a dust collection bucket and an air-dust separation device installed on the dust collection bucket. The mixed air first enters the dust collecting bucket from the air inlet of the dust collecting bucket, and forms a cyclone. When the cyclone is separated, the cyclone will reroll the fine dust that has been deposited at the bottom of the dust collecting bucket, resulting in the dust in the dust collecting bucket. The sundries and dust are always rotating in the dust collecting barrel and are gradually brought into the inside of the gas-dust separation device, and finally filtered out by the air filter of the gas-dust separation device. During the dust collection process of the vacuum cleaner, the deposited dust is repeatedly rolled up again in the dust collecting barrel, which causes the problem that the air-dust separation effect of the existing vacuum cleaner is poor, and the air filter is easily blocked.

The gas-dust separation device is installed on the top of the dust collection chamber body;

The dust collecting chamber body is also provided with a shielding assembly located between the bottom of the dust collecting chamber body and the gas-dust separation device, the shielding assembly has a shielding state and a dumping state, and the shielding assembly is in the shielding state , the inner cavity of the dust collection chamber body is divided into an upper chamber and a lower chamber, and the dust deposited in the lower chamber is prevented from being rolled into the upper chamber, and the shielding assembly is in a dumped state , dump the dust deposited on the shielding assembly in the upper chamber into the lower chamber, and restore to the shielding state.

The shielding assembly includes a shielding member, and a rotating shaft for rotatably installing the shielding member on the inner wall of the dust chamber body, and the shielding member is driven by a driving device around the rotating shaft in the shielding state Toggles between dumped and dumped states.

The shielding assembly includes a shielding member and a rotating shaft for installing the shielding member on the body of the dust collection chamber. The center of gravity of the empty shielding member is below the axis of the rotating shaft, so that the shielding member is kept at The shielding state: when the amount of dust deposited on the shield reaches such that the center of gravity of the shield moves above the center line of the shaft, the shield becomes unstable around the shaft and is shielded by the shield. The state automatically turns to the pouring state.

There is a gap between the edge of the shielding member and the inner wall of the dust collecting chamber body.

The gap is 1 mm to 30 mm.

The distance between the hinge of the rotating shaft and the top of the dust collecting chamber body is 1/2 to 3/4 of the height of the dust collecting chamber body.

The shielding member has a concave collection chamber for collecting dust, and when the shielding member is in the shielding state, the opening of the collection chamber faces upward.

The air inlet is located between the shielding member and the gas-dust separation device, and is arranged close to the gas-dust separation device.

The dust collecting chamber body includes a hollow main body and a bottom cover arranged at the bottom of the main body, and the gas-dust separation device is installed at the top of the main body.

A vacuum cleaner according to the present invention comprises the above-mentioned dust collecting chamber.

The technical solution of the present invention has the following advantages:

1. In the present invention, the shielding assembly has a shielding state and a dumping state. When the shielding assembly is in the shielding state, the inner cavity of the dust collection chamber body is divided into an upper chamber and a lower chamber, and dust deposited in the lower chamber is prevented. Rolled into the upper chamber, when the shielding assembly is in the dumped state, the dust deposited on the shielding assembly in the upper chamber is dumped into the lower chamber, and it is restored to the shielding state. The setting of the shielding component can effectively prevent the dust deposited on the bottom of the dust collection chamber from being rolled up again, thereby effectively collecting and storing dust, reducing the cleaning frequency of the air filter, improving the efficiency of air and dust separation of the vacuum cleaner, and improving its quality ,performance.

2. In the present invention, when the shield is empty, the center of gravity is below the axis of the shaft and close to the bottom of the shield, so as to ensure that the empty shield can be stably balanced with the opening facing upward. After a certain amount of dust is deposited in the shutter, the overall center of gravity of the shutter will move upwards. When the center of gravity moves upward beyond the axis of the rotating shaft, the shutter will become unstable, and the dust will be automatically poured into the bottom when it overturns. After dumping the dust, it returns to the vacant blocking state, and continues to collect the dust. This reciprocating cycle realizes the dust collection and storage, and avoids the secondary roll-up of the cyclone. The shifting of the shutter between the shielding state and the dumping state does not require a driving device to be driven. Therefore, the structure is simple, the manufacturing cost is low, and no additional energy consumption is required, and the user's use cost will not be increased.

Detailed ways

The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

Example 1

As shown in Figures 1-4, a kind of dust collecting room of the present invention comprises:

The dust collecting chamber body has an air inlet 6;

The gas-dust separation device 1 is installed on the top of the dust collecting chamber body;

The dust collecting chamber body is also provided with a shielding assembly located between the bottom of the dust collecting chamber body and the gas-dust separation device 1. The shielding assembly has a shielding state and a dumping state, and the shielding assembly is in a shielding state. state, the inner cavity of the dust collection chamber body is divided into an upper chamber and a lower chamber, and the dust 7 deposited in the lower chamber is prevented from being rolled into the upper chamber, and the shielding assembly is in the In the dumping state, the dust 7 deposited on the shielding assembly in the upper chamber is poured into the lower chamber, and the shielding state is restored.

The setting of the blocking component can effectively prevent the dust 7 that has been deposited on the bottom of the dust collection chamber body from being rolled up again, thereby effectively collecting and storing the dust 7, reducing the cleaning frequency of the air filter, and improving the air and dust separation efficiency of the vacuum cleaner , to improve its quality and performance.

In this embodiment, it is preferable that the shutter assembly includes a shutter 3, and a rotating shaft 5 for installing the shutter 3 on the body of the dust collection chamber, and the center of gravity of the empty shutter is at the axis of the rotating shaft 5 Below the centerline, keep the shutter 3 in the shielding state; when the amount of dust 7 deposited on the shutter 3 reaches the point where the center of gravity of the shutter is moved above the central line of the rotating shaft 5 , the shielding member 3 is unstable and rotates automatically from the shielding state to the dumping state around the rotating shaft 5 .

The transition of the shielding member 3 between the shielding state and the pouring state does not require a driving device to be driven. Therefore, not only the structure is simple, the manufacturing cost is low, but also no additional energy consumption is required, and the user's use cost will not be increased. When the shutter 3 is empty, the center of gravity is below the axis of the rotating shaft 5 and close to the bottom of the shutter 3, so as to ensure that the empty shutter 3 can be stably balanced with the opening facing upward. After the dust in the shutter 3 is deposited to a certain amount, the overall center of gravity of the shutter 3 will move upwards. When the center of gravity moves up and crosses the axis of the rotating shaft 5, the shutter 3 will lose stability, and the dust will be automatically removed when it overturns. Pour it into the bottom, and after dumping the dust, it will return to the vacant blocking state and continue to collect the dust. This reciprocating cycle can realize the collection and storage of dust and avoid the secondary roll-up of the cyclone.

In order to facilitate the flexible rotation of the rotating shaft 5, there is a gap between the edge of the shielding member 3 and the inner wall of the dust collecting chamber body.

When the gap is specifically designed, preferably the gap is 1 mm to 30 mm. This not only facilitates the flexible rotation of the rotating shaft 5, but also ensures that the shutter 3 can effectively prevent the dust 7 deposited on the bottom of the dust collecting chamber body from being rolled up again.

Further, the distance between the hinge of the rotating shaft 5 and the top of the dust collecting chamber body is 1/2 to 3/4 of the height of the dust collecting chamber body. This can prevent the dust 7 deposited on the bottom of the dust collecting chamber body from being rolled up again, and at the same time, leave enough space for the upper chamber to separate the gas and dust.

The shielding member 3 has a concave collecting chamber for collecting dust 7 , and when the shielding member 3 is in the shielding state, the opening of the collecting chamber faces upward.

As shown in FIG. 3 and FIG. 4 , the inner surface and the outer surface of the shielding member 3 are arc-shaped, and the inner surface forms the collection cavity.

The air inlet is located between the shielding member and the gas-dust separation device 1 , and is arranged close to the gas-dust separation device 1 .

In order to facilitate the installation of the shielding assembly, the dust collection chamber body includes a hollow main body 2 and a bottom cover 4 arranged at the bottom of the main body 2 , and the gas-dust separation device 1 is installed on the top of the main body 2 .

Example 2

The difference between Embodiment 2 and Embodiment 1 is that the shutter assembly includes a shutter 3 and a rotating shaft 5 that rotatably installs the shutter 3 on the inner wall of the dust chamber body. The member 3 is driven by the driving device to switch between the shielding state and the dumping state around the rotating shaft 5 . By driving the shutter 3 to switch between the blocking state and the dumping state through the driving device, it is easier to control the switching frequency between the blocking state and the dumping state, and the dust collection effect is better.

A vacuum cleaner according to the present invention includes the above-mentioned dust collecting chamber, which can improve the gas-dust separation efficiency, reduce the cleaning frequency of the air filter, and be more convenient to use.

Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
