For example, a hand-held cleaner such as that shown in FIG. 1, but not limited to, an upright cleaner, a washer, a self-moving cleaning robot, a vehicle cleaner, an air cleaner, and other devices having a suction function that perform filtration using the filter assembly 30, etc. Accordingly, the main body 10 may be the main body 10 of the hand-held cleaner as shown in fig. 1, and may also include, but is not limited to, a main body 10 of an upright cleaner, a main body 10 of a self-moving cleaning robot, a main body 10 of a vehicle-mounted cleaner, a main body 10 of an air cleaner, and other main bodies 10 having a suction function, filtering using the filtering assembly 30, etc., and the embodiment of the present invention is not particularly limited. The cleaning apparatus described in the above and following embodiments is described by way of example with respect to a hand-held cleaner, and this does not constitute an undue limitation of embodiments of the present invention.

Referring to fig. 1, in an embodiment of the present invention, a main body 10 may be implemented in such a manner that the main body 10 includes a housing, various functional components of a cleaning apparatus are disposed in a cavity of the housing, and a dust bucket 12, a handle 13, a base 16, an air outlet 15, and the like are disposed on the housing in addition to a motor cover 11. Wherein, the motor cover 11, the dust barrel 12 and the air outlet part 15 are respectively provided with an air flow channel. The dust barrel 12 is provided with a dust suction opening 122, the dust suction opening 122 can be connected with a dust suction pipe or other dust suction accessories, and a separator 121 is arranged in the dust barrel 12, and the separator 121 comprises, but is not limited to, a cyclone separator. The user can hold the cleaning device through the handle 13 to perform dust collection operation, a control switch (not shown in the figure) is further arranged on the handle 13, a battery assembly 14 and a control chip (not shown in the figure) are arranged in the base 16, the control switch is connected with the control chip, and the control chip is further connected with the motor assembly 20 and the battery assembly 14. The user can input a control instruction to the control chip through the control switch, so that the start and stop of the motor assembly 20 are controlled through the control chip, and the battery assembly 14 is used for providing the electric energy for the electric energy driven functional components of the motor assembly 20, the control chip and the like during operation. The air outlet 15 is provided with an air outlet, air flow can enter the main body 10 from the dust collection opening 122 and then is discharged out of the main body 10 from the air outlet on the air outlet 15, and the air outlet 15 is internally provided with an air outlet filter 151.

The motor assembly 20 is configured to create a negative pressure during operation to create a suction airstream that draws debris near the dust opening 122 into the dust bin 12, the airstream with solid debris entering through the dust opening 122 is subjected to a gas-solid separation by the separator 121, e.g., the separator 121 may be a cyclone separator into which dust enters the cyclone separator tangentially with the airstream at a high velocity from the dust opening 122, the high velocity rotating airstream effectively centrifuging a substantial portion of the dust particles, trapping a substantial portion of the solid debris in the airstream within the dust bin 12. The airflow then flows from the dust bin 12 into the motor housing 11 through the airflow path between the motor housing 11 and the dust bin 12, and the airflow is filtered again by the filter assembly 30, and solid waste, such as small particle dust, remaining in the airflow is trapped by the filter assembly 30 from entering the motor assembly 20. The air flow flows into the air outlet portion 15 through the air flow channel between the motor cover 11 and the air outlet portion 15, and flows out from the air outlet of the air outlet portion 15 after being filtered by the air outlet filter 151.

In the embodiment of the present invention, the filter assembly 30 is detachably mounted in the motor housing 11, and after a user performs a cleaning operation using the cleaning apparatus, the filter assembly 30 may be detached from the motor housing 11, as shown in fig. 1 and 2, and the filter assembly 30 is located outside the motor housing 11, i.e., in a state in which the filter assembly 30 is not mounted in the motor housing 11, so that the user can clean the filter assembly 30 or replace the filter assembly 30 with a new one. The user can install the cleaned filter assembly 30 or a new filter assembly 30 into the motor housing 11, as shown in fig. 3 and 4, the filter assembly 30 is installed in the motor housing 11 and is disposed around the motor assembly 20, at this time, the user can see the cleaning operation through the cleaning device, and the filter assembly 30 filters dust while blocking noise generated when the motor assembly 20 is operated.

Further, in the embodiment of the present invention, the angle value of the second included angle ranges from 70 ° to 110 °. That is, the angle between the axial line of the motor assembly 20 and the axial line of the dust barrel 12 is between 70 ° and 110 °, the filter assembly 30 is disposed around the motor assembly 20, and the air flow flowing out of the dust barrel 12 needs to pass through the filter assembly 20 at a certain angle, so that the flow path of the air flow can be effectively prolonged, the contact time between the air flow and the filter assembly 20 is increased, and the filtering effect of the filter assembly 20 can be improved.

Further, the second included angle has an angle value ranging from 80 ° to 100 °. Further, the angle value of the second included angle is 90 °. That is, the angle between the axial line of the motor assembly 20 and the axial line of the dust bucket 12 is 90 °, and the filter assembly 20 surrounding the outer circumference of the motor assembly 20 may cover the air flow path between the dust bucket 12 and the motor cover 11, so that the air flow in the air flow path passes through the filter assembly 30 and then flows to the motor assembly 20. The filter assembly 30 may further filter the airflow through the airflow path, blocking dust particles retained within the airflow from entering the motor assembly 20.

Further, in the embodiment of the present invention, the range of angle values of the first included angle may be consistent with the range of angle values of the second included angle. I.e. the angle value of the first included angle ranges from 70 degrees to 110 degrees, i.e. the angle between the axial line of the motor cover 11 and the axial line of the dust barrel 12 ranges from 70 degrees to 110 degrees, and the extending direction of the axial line of the motor cover 11 is consistent with the extending direction of the axial line of the motor assembly 20, so that the motor assembly 20 can be conveniently installed, and the filter assembly 30 can be conveniently installed. Accordingly, the angle value of the first included angle may also range between 80 ° and 100 °. Further, the first included angle has an angle value of 90 °. I.e. the angle between the axial line of the motor housing 11 and the axial line of the dust bucket 12 is 90 deg..

Further, in the embodiment of the present invention, the axial line of the motor housing 11 is coaxial with the axial line of the motor assembly 20 and extends in the horizontal direction. The axial line of the dust bucket 12 extends in a vertical direction. To facilitate installation of filter assembly 30 and to allow filter assembly 30 to better fit around motor assembly 20, filter assembly 30 is coaxial with motor assembly 20. When in installation, the filter assembly 30 can be conveniently sleeved on the periphery of the motor assembly 20, so that noise generated by the motor assembly 20 is effectively isolated. The mounting opening 111 on the motor housing 11 is provided along the extension direction of the axial line of the motor housing 11, i.e. the mounting opening 111 is provided on the axial extension line of the motor assembly 20. When the filter assembly 30 is installed through the installation opening 111, the installation opening 111 plays a foolproof role through the limitation of the position and the orientation of the installation opening 111, and the coaxial installation of the filter assembly 30 and the motor assembly 20 is ensured, so that the installation is more convenient and accurate.

Meanwhile, the motor assembly 20 and the filter assembly 30 are arranged along the horizontal direction, so that dust can be prevented from falling vertically from the filter assembly 30 when the user dismounts the filter assembly 30. The line B-B as shown in fig. 3 is the axial line of the motor assembly 20 or the filter assembly 30. The filter assembly 30 is horizontally arranged, and when the filter assembly 30 is installed and detached, all the accessible mounting openings 111 move along the horizontal direction, and when a user takes out the filter assembly 30 from the mounting openings 111, the risk that dust falls off the filter assembly 30 vertically is reduced.

In the embodiment of the present invention, the motor cover 11 may be disposed at different positions according to different arrangement requirements, and in one implementation, referring to fig. 1 to 2, the motor cover 11 is disposed above the dust bucket 12. The motor assembly 20 is fixed in the motor housing 11 and is disposed laterally above the dust bucket 12. Through the filter assembly 30 and the motor assembly 20, the motor cover 11 forms a relatively sealed cavity, and the air flow filtered by the dust barrel 12 enters the motor cover 11 through the air flow channel, and then enters the motor after being filtered by the filter assembly 30. The motor cover 11 is arranged above the dust barrel 12, the distance between the motor cover 11 and the dust barrel is short, the whole volume of the cleaning equipment can be reduced, and meanwhile, when negative pressure is formed, the motor assembly 20 positioned in the motor cover 11 directly acts on the dust barrel 12 through the airflow channel, so that high-speed suction airflow can be formed in the dust barrel 12, garbage can be sucked conveniently, and the gas-solid separation effect of the dust barrel 12 is better. Of course, according to different setting requirements, the motor cover 11 is positioned below the dust barrel 12 in another setting mode.

Whether motor housing 11 is above or below dust bucket 12, filter assembly 30 may cover the airflow path between motor housing 11 and dust bucket 12 such that the airflow within the airflow path passes through filter assembly 30 and then toward motor assembly 20. After separation of the airflow by the separator 121, most of the dust particles are separated from the airflow and trapped within the dust bin 12. However, a small portion of the fine dust particles may flow away with the airflow into the motor cover 11. If tiny dust particles enter the motor assembly 20, they can affect the motor assembly 20 and even damage the motor assembly 20. The filter assembly 30 covers the airflow channel, and can further filter the airflow passing through the airflow channel, so as to block and retain dust particles remained in the airflow, and prevent the dust particles from entering the motor assembly 20. The air flow can flow into the air outlet portion 15 through the air flow channel between the motor cover 11 and the air outlet portion 15, and after being filtered by the air outlet filter 151, the air flow flows out from the air outlet of the air outlet portion 15.

In an embodiment of the present invention, referring to fig. 5 and 6, one implementation of the filter assembly 30 is that the filter assembly 30 includes a filter support 31 and a filter cotton 32. The filter support 31 is of a barrel-shaped structure, one end of the filter support is provided with an opening, the other end of the filter support is closed, and a plurality of vent holes 311 are formed in the side wall of the barrel-shaped structure. The filter cotton 32 is enclosed on the periphery of the side wall of the barrel structure and covers the plurality of ventilation holes 311. When the filter holder 31 is disposed around the outer periphery of the motor assembly 20, the mounting opening 111 is sealed by a closed end cap. The filter holder 31 provides support for the filter cotton 32, and the interior cavity of the filter holder 31 can be used to house the motor assembly 20. When the filter assembly 30 is mounted in the motor housing 11, the filter holder 31 covers the motor assembly 20 in a tub-like structure, and the closed end of the filter holder 31 seals the mounting opening 111, so that a relatively closed space is formed inside the motor housing 11. The air flow flowing into the motor cover 11 can be filtered by the filter cotton 32 and then flows into the barrel structure through the vent hole 311 and then enters the motor assembly 20. Further, the filter assembly 30 may also include, but is not limited to, a HEPA assembly.

Further, in order to make the closed end of the filter holder 31 seal the mounting opening 111 better, an everting flange 312 is provided at the circumferential edge of the closed end, and the outer periphery of the everting flange 312 can abut against the inner wall of the motor housing 11, so that the mounting opening 111 can be sealed effectively, and a relatively closed space is formed inside the motor housing 11.

In the embodiment of the present invention, one possible connection manner between the filter support 31 and the motor cover 11 is that, along the axial direction of the filter assembly 30, sealing rings 33 are respectively disposed at two ends of the filter support 31 in a ring manner. The filter holder 31 can be connected with the inner wall of the motor housing 11 in an interference fit manner by means of a sealing ring 33. The sealing ring 33 includes, but is not limited to, a soft rubber ring such as a rubber ring or a silicone ring or other materials. When the filter assembly 30 is inserted into the motor cover 11, the sealing ring 33 is in interference fit with the motor cover 11 due to the clamping action of the filter support 31 and the inner wall of the motor cover 11, so that the filter support 31 can be stably installed in the motor cover 11. Meanwhile, through the sealing rings 33 at the two ends, the inner cavity of the motor cover 11 can be sealed, and an air flow channel between the motor cover 11 and the dust barrel 12 is positioned between the two sealing rings 33. In this way, after the air flow flowing in from the air flow channel enters between the two sealing rings 33, the air flow can only flow through the filter cotton 32 and the vent hole 311 due to the blocking of the two sealing rings 33, so that the air flow is prevented from flowing from other positions and avoiding the filter cotton 32.

One way to disassemble the filter assembly 30 is to remove the filter assembly 30 from the motor housing 11 when the cleaning device is not in operation, for example, referring to fig. 2, the user may hold the filter support 31, and pull the filter assembly 30 out along the extending direction of the axial line of the motor assembly 20, as shown by the arrow in fig. 2, against the friction force between the sealing ring 33 and the motor housing 11.

When the filter assembly 30 is mounted in the motor housing 11, one end of the opening of the filter holder 31 is inserted into the mounting opening 111 in the opposite direction of the arrow in fig. 2, and the filter assembly 30 is pushed into the motor housing 11 against the friction between the seal ring 33 and the motor housing 11. The filter assembly 30 is considered to be in place when the sealing rings 33 at both ends of the filter holder 31 are completely in contact with the electrode housing or the filter assembly 30 can no longer be moved into the motor housing 11.

Further, with continued reference to fig. 4 to 5, the sealing ring 33 is provided with a sealing flange 331 in a surrounding manner, the extending direction of the sealing flange 331 is opposite to the assembling direction of the filter assembly 30, and the filter assembly 30 is connected with the inner wall of the motor cover 11 in an interference fit manner through the sealing flange 331. The sealing flange 331 and the sealing ring 33 can be of an integrated structure, and the diameter of the sealing ring 33 can be increased through the sealing flange 331, so that the connection between the motor cover 11 and the filter assembly 30 is tighter and more stable, and meanwhile, the tightness of the sealing ring 33 can be further improved.

In order to improve the connection stability between the filter assembly 30 and the motor cover 11, a clamping portion 112 is provided on the inner wall of the motor cover 11, and the filter assembly 30 can be clamped with the clamping portion 112 through a sealing flange 331. The clamping portion 112 and the sealing flange 331 prevent the filter assembly 30 from moving in the axial direction relative to the motor cover 11, so as to avoid the change of the relative position. The sealing flange 331 has a certain deformation, so that when a force is applied by a user, the sealing flange 331 is deformed to extract the filter assembly 30.

It should be noted that, in the embodiment of the present invention, the manner of interference fit connection between the sealing flange 331 and the inner wall of the motor housing 11 and the manner of providing the clamping portion 112 on the inner wall of the motor housing 11 may be implemented separately or may be implemented in combination.

In the embodiment of the present invention, besides the connection between the filter assembly 30 and the motor housing 11 is achieved through the sealing ring 33, or on the basis of the connection between the filter assembly 30 and the motor housing 11 through the sealing ring 33, the connection may be achieved through the following manners: the filter assembly 30 is provided with a first connector and the inner wall of the motor housing 11 is provided with a second connector. The filter assembly 30 is detachably connected to the motor housing 11 by means of a first connection piece and a second connection piece. Depending on the different implementation of the first and second connection, the filter assembly 30 may be magnetically connected to the motor housing 11, and/or snap-fit connected, and/or knob-type connected.

One way of realising this is that the first connector comprises, but is not limited to, a magnet, a piece of iron or other component made of magnetically permeable material. Where the first connector is a magnet, the second connector includes, but is not limited to, a magnet, a piece of iron, or other component made of magnetically permeable material. When the first connecting piece is a sheet iron or other component made of magnetically permeable material, the second connecting piece is a magnet. The first connection members may be provided at both ends of the filter assembly 30 in the axial direction, or at one end thereof, and the second connection members are provided at corresponding positions of the inner wall of the motor housing 11. When the filter assembly 30 is installed in the motor housing 11, the first and second connectors are magnetically coupled together. The first and second connectors may be attached to the filter assembly 30 and motor housing 11 by bonding, fastening, or the like. The number of the first connectors and the second connectors may not be limited, for example, the first connectors may be uniformly disposed around the outer circumference of the end of the filter support 31, or the first connectors may be in a ring structure and sleeved on the end of the filter support 31. Accordingly, the second connecting piece can be one or a plurality of second connecting pieces or an annular structure.

In another implementation manner, the first connecting piece and the second connecting piece are buckle structures in matched connection, and the filter assembly 30 and the motor cover 11 can be connected in a buckle manner through the first connecting piece and the second connecting piece. For example, the first connector includes, but is not limited to, a ball button, and the second connector includes a groove, and the ball button cooperates with the groove to position and connect the filter assembly 30 with the motor housing 11.

In another implementation, the first connecting piece and the second connecting piece are internal/external threads in a matched connection or matched knob slide ways, and the filter assembly 30 and the motor cover 11 can be connected in a knob mode through the first connecting piece and the second connecting piece.

It should be noted that, the implementation manners of the first connecting piece and the second connecting piece may be implemented separately or may be implemented in combination, and the embodiments of the present invention are not specifically limited, and are not described herein in detail.

For the convenience of the user to disassemble and assemble the filter assembly 30, referring to fig. 4, 6 and 7, the closed end of the filter holder 31 is provided with an operating handle 40 on the side facing away from the motor assembly 20. When the cleaning apparatus is not in operation, a user may grasp the operating handle 40 to take out the filter assembly 30 from the motor housing 11 or rotate the filter assembly 30. When the filter assembly 30 is mounted in the motor cover 11, the user can mount the filter assembly 30 in the motor cover 11 by operating the handle 40. Further, the operating handle 40 and the filter support 31 are of a split structure; alternatively, the operating handle 40 and the filter holder 31 are integrally formed.

The technical scheme provided by the embodiment of the invention is explained below in combination with specific application scenes so as to help understanding. In the following application scenario, the cleaning device is exemplified as a hand-held cleaner.
