Detailed Description

In the present application, the "top" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 1. It is to be understood that such directional terms are merely used to facilitate the description of the application and to simplify the description, and are not intended to indicate or imply that the devices or elements so referred to must have a particular orientation, be constructed and operate in a particular orientation, and thus are not to be construed as limiting the application.

An embodiment of the present application provides a dirt cup assembly, referring to FIGS. 1 and 2, which includes a cup body 10 and a dirt separation assembly 20. The cup body 10 is provided with a containing cavity 10a, an air inlet 10b and an air outlet 10c, an air flow path is formed between the air inlet 10b and the air outlet 10c, the containing cavity 10a comprises a first dust collecting cavity 10aa communicated with the air inlet 10b, and the first dust collecting cavity 10aa is positioned at the bottom side of the air inlet 10 b.

The dust separating assembly 20 includes a fine ash separator 22 and a separating part 21, at least a partial region of the fine ash separator 22 being located on the air flow path such that the air flow flowing in from the air inlet 10b flows along the air flow path by rotation, the separating part 21 being located in the first dust collecting chamber 10aa and being disposed eccentrically with respect to the first dust collecting chamber 10aa, the outer dimensions of the separating part 21 gradually decreasing from one end near the fine ash separator 22 to one end far from the fine ash separator 22.

Specifically, a dust separating assembly 20 is provided within the receiving chamber 10a for separating dust from the airflow. The air flow path from the air inlet 10b to the air outlet 10c passes through at least part of the area of the fine ash separator 22, the air flow on the air flow path being in a rotational motion.

The specific structure of the separation portion 21 is not limited. For example, referring to fig. 2, the separating portion 21 is a fine ash collector having a second dust collecting chamber 21a, and the second dust collecting chamber 21a communicates with the fine ash separator 22.

Specifically, the second dust collection chamber 21a is used to collect fine ash in the airflow flowing along the airflow path. The fine ash collector can also disturb the movement of the air flow in the first dust collection chamber 10aa while being capable of collecting fine ash.

The fine ash separator 22 and the receiving chamber 10a may be centered to prevent interference of the rotational movement of the airflow in the airflow path by the dust separating assembly 20. Of course, both may be arranged eccentrically according to the actual situation.

The fine ash separator 22 may be located in only a partial region of the airflow path, or may be located in all regions of the airflow path.

Further, the specific structure of the fine ash separator 22 may be set according to the actual situation.

Referring to fig. 2 and 3, the fine ash separator 22 includes an airflow guide 221 and a dust guide 222, the airflow guide 221 having a first guide passage 221a, the dust guide 222 having a second guide passage 222a, the airflow guide 221 being located at an end of the dust guide 222 facing away from the fine ash collector, the first guide passage 221a being in communication with the air outlet 10c, and the second guide passage 222a being in communication with the second dust collecting chamber 21 a.

It should be noted that the position of the air inlet 10b on the cup 10 needs to be sufficient to enable the air flow to rotate around the central axis of the accommodating cavity 10a after entering the accommodating cavity 10a, for example, the air inlet 10b is disposed on the side wall of the cup 10.

The working principle of the dirt cup assembly of the present application will be described with reference to fig. 2, in which the dust-carrying air flow, after flowing into the accommodating chamber 10a from the air inlet 10b, will perform a rotational movement along the side wall of the accommodating chamber 10 a. Part of the dust (mainly coarse dust having relatively coarse particles) in the air flow is thrown against the side wall of the accommodating chamber 10a by centrifugal force and gravity, and falls down into the first dust collecting chamber 10aa while rotating along the side wall of the accommodating chamber 10 a. While another portion of the relatively fine particle dust may enter the fine ash separator 22 along the airflow path. Thus, the separation of part of dust from the airflow can be realized. Further, the air flow entering the fine ash separator 22 continues to rotate along the air flow path, so as to rotate along the side wall of the first diversion channel 221a, and is discharged from the air outlet 10 c. The dust entering the fine ash separator 22 is rotated while being moved toward the bottom side along the sidewall of the second guide passage 222a by gravity and centrifugal force, and thus collected in the second dust collection chamber 21 a. Thereby, the air flow and dust entering the fine ash separator 22 can be made to move in opposite directions, respectively, so that separation of dust and air flow can be further achieved.

The separation part 21 is eccentrically arranged with respect to the first dust collecting chamber 10aa, meaning that the centers of the two are not coincident, e.g. the central axes of the two are not coincident.

The air flow which moves to the top side while rotating is easily formed in the first dust collection chamber 10aa by the rotating air flow flowing along the air flow path. Therefore, by eccentrically disposing the separating portion 21 with respect to the first dust collecting chamber 10aa, the rotational movement of the air flow in the first dust collecting chamber 10aa can be blocked to disturb the flow of the air flow to prevent the dust collected in the first dust collecting chamber 10aa from being re-lifted.

It should be noted that the region of the dust separating assembly 20 in the first dust collecting chamber 10aa is eccentrically disposed with respect to the first dust collecting chamber 10aa, so that the turbulence effect is required. If other structures are added to the outside of the separation portion 21 so that the center of the overall structure coincides with the center of the first dust collection chamber 10aa, the turbulence effect cannot be achieved.

In addition, the separating part 21 of the present application does not directly block the movement of the air flow by the structure itself, but since the separating part 21 is not overlapped with the center of the first dust collecting chamber 10aa (actually, the center of the rotational movement of the air flow) to disturb the upward rotational movement of the air flow, thereby preventing the dust in the first dust collecting chamber 10aa from being re-lifted, and improving the dust collecting effect.

Thereby, by making the outer dimension of the separating portion 21 gradually decrease from the end near the fine ash separator 22 to the end far from the fine ash separator 22, the turbulence effect of the separating portion 21 near the end of the fine ash separator 22 can be ensured, while the space for collecting dust in the first dust collection chamber 10aa can be increased as much as possible, so that dust can be collected.

The specific shape of the separation portion 21 is not limited, and may be, for example, conical, truncated conical, or the like.

Another embodiment of the application provides a cleaning apparatus comprising a body and a dirt cup assembly in accordance with any of the embodiments of the application, the dirt cup assembly being disposed on the body.

A further embodiment of the application provides a cleaning system comprising a base station for interfacing with a cleaning device according to any of the embodiments of the application and a cleaning device according to any of the embodiments of the application.

Specifically, the cleaning apparatus is a cleaning appliance capable of achieving a dust suction function, such as a dust collector.

The base station is a device that is compatible with the cleaning device. The base station is capable of interfacing with the cleaning apparatus for collecting dust and debris received in the dirt cup assembly. Of course, the base station may have other functions according to the actual situation. For example, the base station may also be used to charge the cleaning device by interfacing with the cleaning device.

The dirt cup assembly of the present application includes a cup body 10 and a dirt separation assembly 20, with an airflow path being defined between an air inlet 10b and an air outlet 10c of the cup body 10. In one aspect, at least a portion of the fine ash separator 22 of the dust separating assembly 20 is positioned in the airflow path such that the airflow flowing in from the air intake 10b flows along the airflow path by rotating. Thus, by providing the fine ash separator 22, dust can be separated from the airflow, resulting in a dirt cup assembly having a better dust separating effect. On the other hand, the separating portion 21 of the dust separating assembly 20 is located in the first dust collecting cavity 10aa and is eccentrically disposed with respect to the first dust collecting cavity 10aa, so as to disturb the airflow in the first dust collecting cavity 10aa, thereby avoiding the dust in the first dust collecting cavity 10aa from being raised again under the driving of the rotating airflow, and further improving the effect of separating dust. Meanwhile, the external dimension of the separating part 21 gradually decreases from the end close to the fine ash separator 22 to the end far away from the fine ash separator 22, so that the turbulence effect of the end of the separating part 21 close to the fine ash separator 22 can be improved, and dust can fall down in the first dust collecting cavity 10aa to be collected, thereby further improving the dust separating effect. Therefore, the dust cup component is arranged eccentrically to perform turbulence, but not additionally provided with the rib turbulence, so that the problem of ash hanging at the rib position is avoided, and the dust cup component can be cleaned and poured conveniently while ensuring a better dust separating effect.

In a specific embodiment, the accommodating chamber 10a includes a first dust collecting chamber 10aa and a separating chamber for providing an air flow path, and the first dust collecting chamber 10aa and the separating chamber are coaxial, that is, the centers of the two are coincident.

Of course, depending on the actual situation, the two may be different, i.e. the centers of the two do not coincide.

In one embodiment, referring to FIG. 2, the fine ash separator 22 is disposed coaxially with the first dust collection chamber 10 aa.

Specifically, the fine ash separator 22 is eccentrically disposed with respect to the first dust collecting chamber 10aa, and the separating portion 21 is coaxially disposed with the first dust collecting chamber 10aa, i.e., the centers thereof are on the same axis. That is, the fine ash separator 22 is not coaxial with the separating portion 21, i.e., the centers of the two are not on the same axis. Thus, by relatively staggering the two, the air flow in the first dust collection chamber 10aa can be further prevented from rotating to the top side around the dust separating assembly 20, and the separation effect of dust and air flow can be enhanced.

In one embodiment, referring to FIG. 2, the dust separating assembly 20 includes a filter assembly 23, the filter assembly 23 being disposed on an outer peripheral side of the fine ash separator 22, at least a portion of the fine ash separator 22 and at least a portion of the filter assembly 23 being disposed in the airflow path.

Specifically, the filter assembly 23 may be located in only a partial region or may be located in all regions of the airflow path. The air flow flowing in from the air inlet 10b passes through the filter assembly 23 and the fine ash separator 22 in this order while rotating, and is discharged through the air outlet 10 c.

The filter assembly 23 is used to separate dust, such as a filter housing, from the airflow along the airflow path. The filter assembly 23 may be used to block hair, fibers, coarse ash, etc., and its pore size determines the size of dust that can pass through the filter assembly 23 into the fine ash separator 22.

By providing the filter assembly 23 on the outer peripheral side of the fine ash separator 22, it is possible to prevent excessive dust from entering into the fine ash separator 22, to prevent the excessive dust from decreasing the separation effect of the fine ash separator 22, so that excessive dust is entrained in the air flow discharged from the air outlet 10c, and thus the separation effect of the dust can be ensured.

In one embodiment, the filter assembly 23, the fine ash separator 22 and the center of the receiving chamber 10a are all coincident, and the fine ash collector is disposed eccentrically with respect to the first dust collection chamber 10 aa.

In one embodiment, the fine dust collector is located at the bottom side of the dust guide 222, the airflow guide 221 is located at the top side of the dust guide 222, and the air outlet 10c is located at the top side of the airflow guide 221.

In one embodiment, referring to fig. 2, the dust separating assembly 20 includes a dust separating cover 24, the dust separating cover 24 is located on a side of the filtering assembly 23 facing away from the air outlet 10c, and a first dust collecting chamber 10aa is defined between the dust separating cover 24 and the bottom wall of the cup body 10.

Specifically, the dust-separating cover 24 is located between the filtering component 23 and the first dust collecting cavity 10aa, and can prevent dust from being raised again under the driving of the airflow in the first dust collecting cavity 10aa, so that the separation effect of dust in the airflow can be improved.

It should be noted that, there is a space between the dust-separating cover 24 and the sidewall of the cup body 10, so that the dust falls into the first dust collecting cavity 10aa under the action of centrifugal force and gravity, and the specific structure thereof is not limited.

For example, the cross-sectional dimension of the dust separating cover 24 gradually increases from the side away from the first dust collecting chamber 10aa toward the side closer to the first dust collecting chamber 10 aa. Thereby, the influence of the dust shield 24 on the falling of the dust into the first dust collecting chamber 10aa can be reduced, the blocking effect of the dust shield 24 on the dust in the first dust collecting chamber 10aa can be improved, and the dust in the first dust collecting chamber 10aa can be prevented from being raised again.

In an embodiment, referring to fig. 2, an end of the airflow guiding member 221, which is close to the dust guiding member 222, extends into the second guiding channel 222a, and is spaced from the sidewall of the second guiding channel 222a, so that an air gap 22a is formed at the spacing, and the air inlet 10b is respectively communicated with the air outlet 10c and the second dust collecting chamber 21a through the air gap 22 a.

Specifically, the air flow passing through the filter assembly 23 is first rotated around the outer wall surface of the air flow guide 221 and moved to the bottom side to pass through the air passing hole 22a. Then enters the first diversion channel 221a from the bottom end and moves to the air outlet 10c along the side wall of the first diversion channel 221a while rotating. While dust (e.g., fine dust) entrained in the air flow is rotated around the outer wall surface of the air flow guide 221 with the air flow and passed through the air passing opening 22a, and then is rotated and moved to the bottom side along the sidewall of the second guide passage 222a by centrifugal force and gravity to move into the second dust collecting chamber 21 a.

The specific shape of the first and second flow-guiding channels 221a and 222a is not limited, for example, the first flow-guiding channel 221a is cylindrical to facilitate the rotational movement of the air flow within the first flow-guiding channel 221 a.

For another example, referring to fig. 2 and 3, the second diversion channel 222a gradually converges from a side far from the fine ash collector toward a side near the fine ash collector.

That is, by contracting the sectional area of the second flow guide passage 222a, dust can be more intensively collected into the second dust collection chamber 21a, and at the same time, the sectional area of the second flow guide passage 222a at the position where it communicates with the second dust collection chamber 21a can be reduced, the dust in the second dust collection chamber 21a can be prevented from being raised again, and the separation effect of dust in the air flow can be improved.

The specific structural shape of the second guide passage 222a is not limited, and it may be conical or circular truncated cone-shaped, and it is possible to facilitate the dust to fall into the second dust collection chamber 21 a.

The specific structural shape of the second dust collection chamber 21a may be determined according to the external dimensions of the separating part 21, such as a conical shape or a truncated cone shape, etc.

Illustratively, the second dust collecting chamber 21a gradually expands from a side away from the dust guide 222 toward a side close to the dust guide 222.

In one embodiment, referring to fig. 2, the end of the dust guiding member 222 near the fine dust collector extends into the second dust collecting chamber 21 a.

On the one hand, the length of the second diversion channel 222a can be increased as much as possible under the condition that the whole size of the dust cup assembly is unchanged, so as to prevent the second diversion channel 222a from being too short, and dust is easy to lift and move again along with the airflow. On the other hand, the fine ash collector is not downsized, and the turbulence effect of the fine ash collector on the air flow in the first dust collection chamber 10aa can be ensured.

In addition, the fine ash collector may be eccentrically disposed with respect to the dust deflector 222. Thereby, the dust deflector 222 and the accommodating chamber 10a can be kept centered and coincident while ensuring that the fine dust collector is eccentrically disposed with respect to the first dust collecting chamber 10 aa. Meanwhile, the dust guide 222 can also form turbulence in the second dust collecting chamber 21a, so as to further prevent the dust in the second dust collecting chamber 21a from being raised again.

In an embodiment, referring to fig. 2, the fine ash separator 22 further includes a baffle member 223, the baffle member 223 is located between the airflow guiding member 221 and the air outlet 10c, and the baffle member 223 is spaced from an end surface of the airflow guiding member 221 near the air outlet 10c, so that a third diversion channel 22b communicating the air outlet 10c and the first diversion channel 221a is formed at the spacing.

Specifically, by providing the barrier 223, the third flow guide passage 22b can be formed between the barrier 223 and the air flow guide 221, so that the air flow path is prolonged, and at the same time, dust in the air flow can be easily separated during movement along the third flow guide passage 22b due to the barrier effect of the barrier 223, so that the degree of cleanliness of the air flow flowing out of the air outlet 10c can be ensured.

The specific shape of the barrier 223 and the airflow guide 221 is not limited.

Illustratively, the airflow guide 221 includes a cylindrical body having a first flow guide channel 221a, and an end surface located on a side of the cylindrical body adjacent to the air outlet 10 c. The barrier 223 is spaced apart from the end surface to form the third flow guide passage 22b, and a partial region of the barrier 223 protrudes into the first flow guide passage 221a to guide the air flow to move along the third flow guide passage 22b by rotation.

In one embodiment, the cup body 10 comprises a dust outlet positioned at the bottom side of the first dust collecting cavity 10aa and a cover body which can be opened and closed and is arranged at the dust outlet.
