Wherein, air flow channels are arranged between the motor cover 11 and the dust barrel 12 and between the motor cover and the air outlet part 15. 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, a separator 121 is arranged in the dust barrel 12, and the separator 121 includes but is not limited to a cyclone separator. A user can hold the cleaning equipment by the handle 13 to perform dust collection operation, the handle 13 is further provided with a control switch (not shown in the figure), the base 16 is internally provided with a battery assembly 14 and a control chip (not shown in the figure), 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. A user can input a control instruction to the control chip through the control switch, so as to control the start and stop of the motor assembly 20 through the control chip, and the battery assembly 14 is used for providing electric energy during operation for the electric energy driven functional components such as the motor assembly 20 and the control chip. The air outlet portion 15 is provided with an air outlet, the air flow can enter the main body 10 from the dust collection port 122, and then is discharged from the main body 10 through the air outlet on the air outlet portion 15, and an air outlet filtering member 151 is arranged in the air outlet portion 15.

The motor assembly 20 is configured to create a negative pressure during operation to create a suction airflow that draws the debris near the suction opening 122 into the dirt cup 12, and the airflow with the solid debris entering through the suction opening 122 is subjected to gas-solid separation by the separator 121, e.g., the separator 121 can be a cyclone separator, and the dust enters the cyclone separator at a high speed and tangentially along with the airflow from the suction opening 122, and the airflow rotating at the high speed can effectively separate most of the dust particles centrifugally, and trap most of the solid debris in the airflow in the dirt cup 12. Then, the airflow flows from the dust bin 12 to the motor cover 11 through the airflow channel between the motor cover 11 and the dust bin 12, the airflow is filtered by the filter assembly 30 again, and solid garbage such as small-particle dust still remaining in the airflow is intercepted by the filter assembly 30 and prevented from entering the motor assembly 20. The airflow passes through the airflow channel between the motor cover 11 and the air outlet portion 15, flows into 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 filtering member 151.

In the embodiment of the present invention, the filter assembly 30 is detachably mounted in the motor cover 11, and after a user uses the cleaning device to perform a cleaning operation, the filter assembly 30 can be detached from the motor cover 11, as shown in fig. 1 and 2, and the filter assembly 30 is located outside the motor cover 11, that is, in a state where the filter assembly 30 is not mounted in the motor cover 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 filter assembly 30 after the clearance in motor cover 11, perhaps with new filter assembly 30 in, as the state shown in fig. 3 and fig. 4, filter assembly 30 installs in motor cover 11 to enclose and establish in motor assembly 20 periphery, at this moment, the user sees the clean operation of accessible cleaning device, and filter assembly 30 filters the dust simultaneously, the noise that the separation motor assembly 20 produced during operation.

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 bucket 12 is between 70 ° and 110 °, the filter assembly 30 is disposed around the motor assembly 20, and the airflow flowing out of the dust bucket 12 needs to pass through the filter assembly 20 at a certain angle, so that the flow path of the airflow can be effectively extended, the contact time between the airflow 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 between 80 ° and 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 barrel 12 is 90 °, and the filter assembly 20 arranged around the periphery of the motor assembly 20 can cover the airflow channel between the dust barrel 12 and the motor cover 11, so that the airflow in the airflow channel passes through the filter assembly 30 and then flows to the motor assembly 20. The filter assembly 30 further filters the airflow passing through the airflow path to trap dust particles trapped in the airflow from entering the motor assembly 20.

Further, in the embodiment of the present invention, the range of the angle value of the first included angle may be consistent with the range of the angle value of the second included angle. That is, the range of the angle value of the first included angle is between 70 ° and 110 °, that is, the angle between the axial line of the motor cover 11 and the axial line of the dust bucket 12 is between 70 ° and 110 °, 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 installation of the motor assembly 20 can be facilitated, and the installation of the filter assembly 30 can also be facilitated. Accordingly, the first angle may also range in value from 80 ° to 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 dirt-bin 12 is 90 deg..

Further, in the embodiment of the present invention, the axial line of the motor cover 11 is coaxial with the axial line of the motor assembly 20 and both extend in the horizontal direction. The axial line of the dust bucket 12 extends in the vertical direction. To facilitate installation of the filter assembly 30 and to allow the filter assembly 30 to better surround the motor assembly 20, the filter assembly 30 is coaxial with the motor assembly 20. When the motor assembly 20 is installed, 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 can be effectively isolated. The mounting opening 111 on the motor cover 11 is disposed along the extending direction of the axial line of the motor cover 11, that is, the mounting opening 111 is disposed on the axial extending line of the motor assembly 20. When filter assembly 30 was installed through installing port 111, through the injecing of installing port 111 position and orientation, installing port 111 played the fool-proof effect, had ensured filter assembly 30 and motor element 20's coaxial arrangement to make the installation more convenient, accurate.

Meanwhile, the motor assembly 20 and the filter assembly 30 are both arranged along the horizontal direction, so that dust can be prevented from vertically falling off from the filter assembly 30 when a user dismantles the filter assembly 30. Line B-B as shown in fig. 3 is the axial line of the motor assembly 20 or the filter assembly 30. Filter assembly 30 level sets up, when installation and dismantlement, all can remove along the horizontal direction through installing port 111, and the user has reduced the vertical risk that drops of dust from filter assembly 30 when taking out filter assembly 30 from installing port 111.

In the embodiment of the present invention, the motor cover 11 can be disposed at different positions according to different setting requirements, and one way to achieve this is that, referring to fig. 1 to 2, the motor cover 11 is located above the dust bucket 12. The motor assembly 20 is fixed in the motor housing 11 and is disposed laterally above the dirt cup 12. Through filter assembly 30 and motor assembly 20 for motor cover 11 forms a relative sealed cavity, and the air current after dust bucket 12 filters passes through the air current passageway and gets into in motor cover 11, and the air current passes through filter assembly 30 after the filtration, gets into in the motor. Motor cover 11 establishes in the top of dirt bucket 12, and the distance between the two is short, reducible cleaning device's holistic volume, simultaneously, is located motor element 20 in motor cover 11 when forming the negative pressure, accessible airflow channel direct action in dirt bucket 12 to make the inside fast-speed suction air current of formation of dirt bucket 12, when being convenient for suck rubbish, make the effect of dirt bucket 12 gas-solid separation also better. Of course, according to different setting requirements, the motor cover 11 is located below the dust bucket 12 in another setting mode.

Whether the motor cover 11 is located above or below the dust bucket 12, the filter assembly 30 can cover the airflow channel between the motor cover 11 and the dust bucket 12, so that the airflow in the airflow channel passes through the filter assembly 30 and then flows to the motor assembly 20. After the airflow is separated by the separator 121, most of the dust particles will be separated from the airflow and trapped in the dust barrel 12. However, a small proportion of small dust particles will flow away with the airflow into the motor casing 11. If minute dust particles enter the motor assembly 20, they may affect the motor assembly 20 and even damage the motor assembly 20. The filter assembly 30 covers the airflow path to further filter the airflow passing through the airflow path, so as to block and retain the dust particles remaining in the airflow and prevent the dust particles from entering the motor assembly 20. Airflow can flow into the air outlet part 15 through an airflow channel between the motor cover 11 and the air outlet part 15, and the airflow flows out from an air outlet of the air outlet part 15 after being filtered by the air outlet filtering piece 151.

In the embodiment of the present invention, referring to fig. 5 and 6, one way to realize the filter assembly 30 is that the filter assembly 30 includes a filter support 31 and a filter cotton 32. The filter holder 31 is a barrel-shaped structure, one end of which is open and the other end of which is closed, and a plurality of vent holes 311 are arranged on the side wall of the barrel-shaped structure. The filter cotton 32 is arranged around the periphery of the side wall of the barrel-shaped structure and covers the plurality of vent holes 311. The filter holder 31 is closed and sealed at the mounting opening 111 by a closed end thereof when it is disposed around the outer periphery of the motor assembly 20. The filter holder 31 provides support for the filter cotton 32, and the inner cavity of the filter holder 31 can be used for accommodating the motor assembly 20. When the filter assembly 30 is installed in the motor cover 11, the filter bracket 31 covers the motor assembly 20 in the barrel-shaped structure, and the closed end of the filter bracket 31 seals the installation opening 111, so that a relatively closed space is formed inside the motor cover 11. The airflow flowing into the motor cover 11 can be filtered by the filter cotton 32, and then flows into the barrel structure through the vent holes 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 enable the closed end of the filter support 31 to better seal the mounting opening 111, the outward-turning folding edge 312 is arranged on the circumferential edge of the closed end, and the periphery of the outward-turning folding edge 312 can abut against the inner wall of the motor cover 11, so that the mounting opening 111 can be effectively sealed, and a relatively closed space is formed inside the motor cover 11.

In the embodiment of the present invention, an achievable connection manner between the filter bracket 31 and the motor cover 11 is that, along the axial direction of the filter assembly 30, two ends of the filter bracket 31 are respectively provided with a sealing ring 33 in an encircling manner. The filter bracket 31 can be connected with the inner wall of the motor cover 11 in an interference fit mode through a sealing ring 33. The sealing ring 33 includes but is not limited to a rubber ring or a silicone ring or a soft rubber ring made of other materials. When filter assembly 30 entered motor cover 11, based on the clamping effect of filtering support 31 and motor cover 11 inner wall for sealing washer 33 and motor cover 11 interference fit, thereby make filtering support 31 can install in motor cover 11 steadily. Meanwhile, the sealing rings 33 at the two ends can seal the inner cavity of the motor cover 11, and an air flow channel between the motor cover 11 and the dust bucket 12 is positioned between the two sealing rings 33. In this way, after the airflow flowing in from the airflow channel enters between the two sealing rings 33, the airflow can only flow through the filter cotton 32 and the vent hole 311 due to the obstruction of the two sealing rings 33, so that the airflow is prevented from flowing from other positions and avoiding the filter cotton 32.

One way of mounting and dismounting the filter assembly 30 is that when the cleaning device is not in operation, the user can take out the filter assembly 30 from the motor housing 11, for example, referring to fig. 2, the user can hold the filter holder 31 by hand, and overcome the friction between the sealing ring 33 and the motor housing 11 along the extending direction of the axial line of the motor assembly 20, for example, in the manner shown by the arrow in fig. 2, to extract the filter assembly 30.

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

Further, with continued reference to fig. 4 to 5, a sealing flange 331 is annularly disposed on the sealing ring 33, an extending direction of the sealing flange 331 is opposite to an assembling direction of the filter assembly 30, and the filter assembly 30 may be connected with the inner wall of the motor cover 11 through the sealing flange 331 in an interference fit manner. The sealing flange 331 and the sealing ring 33 can be of an integrated structure, 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 filtering component 30 is more compact and stable, and meanwhile, the sealing performance 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 arranged 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 can prevent the filter assembly 30 from moving along the axial line direction relative to the motor cover 11, thereby avoiding the change of the relative position. The sealing flange 331 has a certain deformability, so that the filtering assembly 30 can be extracted by deforming the sealing flange 331 when a force is applied by a user.

It should be noted that, in the embodiment of the present invention, the manner of the sealing flange 331 being in interference fit with the inner wall of the motor cover 11 and the manner of the clamping portion 112 being disposed on the inner wall of the motor cover 11 can be implemented separately or combined together.

In the embodiment of the present invention, in addition to the connection between the filter assembly 30 and the motor cover 11 through the sealing ring 33, or on the basis of the connection between the filter assembly 30 and the motor cover 11 through the sealing ring 33, the connection can be achieved through the following methods: the filter assembly 30 is provided with a first connecting piece, and the inner wall of the motor cover 11 is provided with a second connecting piece. Through the first connecting piece and the second connecting piece, the detachable connection between the filter assembly 30 and the motor cover 11 is realized. According to different implementations of the first connector and the second connector, the filter assembly 30 and the motor cover 11 may be magnetically connected, and/or may be connected by a snap connection, and/or may be connected by a knob connection.

In one implementation, the first connecting member includes, but is not limited to, a magnet, a piece of iron, or other member made of a magnetically permeable material. When the first connecting member is a magnet, the second connecting member includes, but is not limited to, a magnet, an iron piece, or other member made of a magnetically permeable material. When the first connecting piece is an iron sheet or other parts made of magnetic conductive materials, the second connecting piece is a magnet. The first connecting member may be provided at both ends of the filter assembly 30 in the axial direction, or at one end thereof, and the second connecting member may be provided at a corresponding position on the inner wall of the motor cover 11. When the filter assembly 30 is installed in the motor cover 11, the first and second connectors are magnetically coupled together. The first connecting member and the second connecting member can be connected to the filter assembly 30 and the motor cover 11 by bonding, fastening, or the like. The number of the first connecting pieces and the second connecting pieces is not limited, for example, a plurality of first connecting pieces may be uniformly arranged on the periphery of the end portion of the filter support 31 in a ring shape, or the first connecting pieces may be in a ring-shaped structure and are sleeved on the end portion of the filter support 31. Accordingly, the second connecting member may be one or more, or a ring structure.

In another implementation manner, the first connecting member and the second connecting member are snap-fit structures that are connected in a matching manner, and the filter assembly 30 and the motor cover 11 can be connected in a snap-fit manner through the first connecting member and the second connecting member. For example, the first connecting member includes, but is not limited to, a ball button, and the second connecting member is a groove, and the ball button and the groove cooperate to position and connect the filter assembly 30 and the motor cover 11.

In another implementation, the first and second connecting members are internal/external threads or knob slides that are engaged, and the filter assembly 30 and the motor cover 11 are rotatably connected via the first and second connecting members.

It should be noted that, the implementation manners of the first connecting element and the second connecting element 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 in detail herein.

In order to facilitate the user to disassemble and assemble the filter assembly 30, referring to fig. 4, 6 and 7, the closed end of the filter bracket 31 is provided with an operating handle 40 at the side facing away from the motor assembly 20. When the cleaning apparatus is not in operation, a user may grip the operating handle 40 to remove the filter assembly 30 from the motor cover 11 or rotate the filter assembly 30. When the filter assembly 30 is mounted to the motor cover 11, the user can mount the filter assembly 30 to the motor cover 11 by manipulating the handle 40. Further, the operating handle 40 and the filtering bracket 31 are of a split structure; alternatively, the operating handle 40 and the filter holder 31 are integrally formed.
