Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 and 6 show schematic structural diagrams of a handheld cleaning device provided by an embodiment of the application. The handheld cleaning device provided by the embodiment of the application can be a handheld dust collector. As shown in fig. 1, the hand-held cleaning device comprises: main part 200, cyclone separation device 1, air inlet duct 2, collection device 3 and handle 7. Wherein the main body 200 houses a suction unit 4 that generates a suction airflow. In this embodiment, the suction unit 4 includes a motor and a fan, and the motor is used for driving the fan to rotate to generate suction airflow. The cyclonic separating apparatus 1 is used to separate dirt and dust from a suction airflow. The cyclonic separating apparatus 1 has a longitudinal axis 111. The suction airstream is caused to rotate helically about a longitudinal axis 111 within the cyclonic separating apparatus 1. An inlet air duct 2 is located upstream of the cyclonic separating apparatus 1 for drawing in airflow and directing it to the cyclonic separating apparatus 1. The air inlet duct 2 has an air inlet communicating with the outside or a floor cleaning accessory, and the air flow mixed with dust enters the air inlet duct 2 through the air inlet and is guided to the cyclone separation device 1. The collecting means 3 is located downstream of the cyclonic separating apparatus 1 and is in communication with the cyclonic separating apparatus 1 and serves to collect separated dirt and dust. The handle 7 comprises a grip 700 extending at an angle to the longitudinal axis 111. As shown in fig. 1, the grip 700 is located on one side of the longitudinal axis 111, so that the longitudinal axis 111 of the cyclonic separating apparatus 1 does not pass through the grip 700. The air inlet duct 2 and the collecting device 3 are both located on the side of the longitudinal axis 111 having the holding portion 700.

In the technical scheme provided by the embodiment of the application, the collecting device 3 is separated from the cyclone separation device 1, so that the collecting device 3 can contain more dust; the holding part 700 of the handle 7 is arranged on one side of the longitudinal axis 111 of the cyclone separation device 1, the air inlet duct 2 and the collecting device 3 are both positioned on one side of the longitudinal axis 111 with the holding part 700, the structure is more compact on the premise that the smoothness of air flow in the air duct is ensured so as not to influence the suction force and the dust removal capacity, the size of the handheld cleaning equipment is reduced, and the use by a user is facilitated.

As shown in fig. 1, the axis 21 of the inlet duct 2 is arranged parallel to the longitudinal axis 111 of the cyclonic separating apparatus 1. Firstly, from the outward appearance hand-held type cleaning device's outline is more regular, secondly is favorable to shortening whole horizontal longitudinal dimension, helps improving hand-held type cleaning device overall structure's compactness. Accordingly, as shown in fig. 2, the air inlet duct 2 communicates with the cyclone separation apparatus 1 through the dust inlet 114 of the cyclone separation apparatus 1. The airflow in the inlet duct 2 enters the cyclonic separating apparatus 1 tangentially after passing through the dust inlet 114 so that dirty air entering the cyclonic separating apparatus 1 is forced to follow a helical path around the interior of the separating drum 11 of the cyclonic separating apparatus 1.

In the orientation shown in figure 1, the longitudinal axis 111 of the cyclonic separating apparatus 1 extends in a horizontal direction. The air inlet duct 2 and the collecting device 3 are both positioned below the cyclone separation device 1. I.e. the axis 21 of the inlet air duct 2 and the longitudinal axis 111 are parallel to each other but do not coincide. The air inlet duct 2 and the collecting device 3 are arranged along the extending direction of the longitudinal axis 111, and the collecting device 3 is close to the holding part 700 of the handle 1.

In particular, referring to figure 2, the cyclonic separating apparatus 1 comprises a separating vessel 11 through which passes a longitudinal axis 111. The separation tub 11 has a first end 1101 remote from the main body 200 and a second end 1102 close to the main body 200, and a tub wall 1103 located between the first end 1101 and the second end 1102. The collecting device 3 is communicated with the separating tub 11 through a dust outlet 115, and the dust outlet 115 is located on the tub wall 1103. The dust inlet 114 is at least partially offset from the dust outlet 115 along the longitudinal axis 111. It should be noted that, in the present embodiment, the at least partial misalignment of the dust inlet and the dust outlet along the longitudinal axis 111 can be simply understood as: a line connecting a center of a shape of the mouth end surface of the dust inlet (hereinafter referred to as a first center for convenience of description) and a center of a shape of the mouth end surface of the dust outlet (hereinafter referred to as a second center for convenience of description) makes an angle with a first reference line, and the angle may be an acute angle of 5 degrees, 10 degrees, 30 degrees, or the like. Wherein the first reference line may pass through the first center and be parallel to a straight line of the longitudinal axis 111; or a line passing through the second center and parallel to the longitudinal axis 111.

Referring to fig. 2, the first end 1101 of the cyclonic separating apparatus 1 has a fixedly located bottom cover. The inlet duct 2 is located adjacent a first end 1101 of the cyclonic separating apparatus 1 and the collecting apparatus 3 is located adjacent a second end 1102 of the cyclonic separating apparatus 1. The second end 1102 of the separation tub 11 is provided with a vent communicating with the main body 200, through which the separated airflow exits the separation tub 11. The air mixed with dust enters the separation barrel 11 from the air inlet duct 2, and then is separated in the separation barrel 11 under the action of centrifugal force, the dust in the air finally enters the collecting device 3 for collection, and the clean air after dust removal is discharged from the separation barrel 11 and enters the main body 200.

As shown in fig. 1, the main body 200 further includes a battery pack 8 for supplying power to the suction unit 4. The battery pack 8 may also be located on the side of the longitudinal axis 111 having the grip portion 700 of the handle 7. In an implementable embodiment, the battery pack 8 may be located between the collecting device 3 and the grip 700 of the handle 7. In another aspect, the collecting device 3 is located between the air inlet duct 2 and the battery pack 8. Further, in order to improve the compactness of the structure, the battery pack 8 may be disposed in close contact with the side wall of the collecting device 3.

With continued reference to figures 1 and 2, the collecting means 3 comprises a bin extending from the outer wall of the separating chamber of the cyclonic separating apparatus in a direction away from the separating chamber. Specifically, referring to fig. 1, the cyclone separating apparatus 1 includes a separating tub 11; the collecting device 3 is positioned outside the separating barrel 11 and is communicated with the separating barrel 11; the collecting device 3 includes a tub body extending from the outer wall of the separation tub 11 toward a direction away from the separation tub 11. As shown in fig. 1, the separation tub 11 of the cyclone 1 is horizontally disposed. The barrel body of the collecting device 3 is arranged below the separating barrel 11, and the collecting device 3 can be arranged vertically or nearly vertically to the separating barrel 11. In particular, the tub of the collecting device 3 also comprises an axis L1 along its extension and through the cover 31, which axis L1 is arranged at an angle to the longitudinal axis 111 of the separation chamber. For example, the angle α shown in fig. 1 is between 30 and 150 degrees. In a particular embodiment, the angle α may be selected to be 75 degrees, 90 degrees, and the like.

Referring to fig. 1, 2 and 3, in order to pour ash, an ash pouring port 32 and a cover 31 capable of opening the ash pouring port movably are provided at the bottom of the barrel body of the collecting device 3 far away from the separating barrel 11. Referring to fig. 3, 4 and 5, the ash discharge port 32 is an L-shaped opening extending from the bottom to the wall of the barrel of the collecting device 3; accordingly, as shown in fig. 5, the cover 31 has an L-shaped configuration that fits into the L-shaped opening. The ash pouring port with the structure has high ash pouring efficiency; in addition, when the user dumps the handheld cleaning equipment, the user does not need to rightly position the handheld cleaning equipment, and the garbage in the barrel body of the collecting device can also come out of the handheld cleaning equipment.

Specifically, as shown in fig. 5, the cover 31 has two opposite sides, namely a first side 316 and a second side 317; the position of the ash pouring port 32 corresponding to the first side edge 316 is movably connected with the first side edge 316; the position of the dust pouring port 32 corresponding to the second side edge 317 is detachably connected with the second side edge 317. The movable connection can be a hinge joint, and the detachable connection can be realized by a clamping hook. For example, as shown in fig. 5, the cover 3 of L-shaped structure has a straight portion 311 and a bent portion 312. One side of the straight portion 311, which is far away from the bending portion 312, is provided with a rotating shaft, and two ends of the rotating shaft can be respectively hinged with the opening edge (i.e. the barrel wall of the collecting device) at the dust pouring opening. As shown in fig. 5, 6 and 7, a hook 314 is disposed on a side of the bending portion 312 away from the straight portion 311, and a flange 315 cooperating with the hook 314 is disposed at a position corresponding to the edge of the ash pouring opening 32. As shown in fig. 7, the hooks 314 snap onto the flanges 315 so that the lid 31 is held in the closed position; when the catch 314 is released, one side of the cover 31 is disengaged from the collecting device 3, as shown in figure 3. In practice, the hook may have an elastic deformation capability, so that when an outward force is applied to the uppermost portion of the hook (e.g. when a user applies an opening motion to the hook), the hook is elastically deformed away from the flange, thereby separating one side of the sealing cover from the ash pouring opening.

Still further, as shown in fig. 6 and 7, the collecting device 3 may be provided with a release button 9 for facilitating the user to release the catch. As shown in fig. 7 and 8, the release button 9 includes an operation portion 91 and a driven portion 92 connected to the operation portion 91. The follower 92 corresponds to the hook 314. The fixing part between the operating part and the driven part is connected with the outer side wall of the barrel body of the collecting device 3, and the operating part and the driven part can rotate relative to the fixing part. For example, when the user presses the operating part, the driven part tilts upwards to generate an outward releasing force applied to the hook, so that the hook is separated from the flange. When the user connects the hook to the flange, the driven part is pressed down to tilt the operation part.

Here, it should be noted that: the detachable connection of the closure to the bowl of the collection device can also be achieved using other structures known in the art, not limited to the hook and flange structure described above. For various specific implementations of the detachable connection in the prior art, reference may be made to the corresponding contents, which are not described in detail herein.

The outer wall of the separation chamber of the cyclone separation device 1 is provided with a dust outlet 115, and correspondingly, as shown in fig. 10, the barrel body of the collection device 3 is provided with a connector 318 which is connected with the dust outlet 115 at the top part close to the separation chamber. The top of the barrel of the collection device 3 also includes an arch 319 that forms the outer wall of the separation chamber, and the interface 318 is located on the arch 319. Alternatively, as shown in fig. 14, the top of the barrel of the collecting device 3 near the separation chamber is provided with a connector 318 protruding from the top of the barrel and coupled with the dust outlet 115; the top of the port 318 is provided with an arch that forms the outer wall of the separation chamber.

Referring to the hand-held cleaning appliance shown in fig. 1, the handle 7 is provided on the main body 200; the collecting device 3 is located between the handle 7 and the inlet air duct 2, and an axis 21 of the inlet air duct 2, which passes through the inlet opening, extends through the collecting device 3 and the handle 7. The battery pack 8 is arranged between the collecting device 3 and the handle 7. The axis 21 of the inlet air duct 2, which passes through the inlet opening, extends through the collecting device 3 and the handle 7 and also through the battery pack 8. The suction unit 4 is located above the battery pack 8.

In particular, the battery pack 8 may be disposed within the battery pack compartment. Referring to fig. 1, the main body 200 further includes a battery pack chamber for receiving the battery pack 8, the suction unit 4 is located at one end of the battery pack chamber, and the handle 7 is connected to the other end of the battery pack chamber. The cyclonic separating apparatus 1 is located above the collecting apparatus 3. The battery pack 8 has an axis L2 extending along its length, the axis L2 may also be at an angle β of between 30 and 150 degrees to the longitudinal axis 111 of the cyclonic separating apparatus 1. In the embodiment shown in fig. 1, the lengthwise direction of the battery pack 8 is parallel to the axial direction passing through the grip portion 700 of the handle 7. Namely, the battery pack 8 has an axis L2 extending in the longitudinal direction thereof; the handle 7 has an axis L3 extending through the grip 700 in a direction away from the main body 200; the axis L2 may be parallel to the axis L3.

It is mentioned above that the axis L1 of the barrel of the collecting device 3 may also be parallel to the direction of the axis L3 of the grip 700 through the handle. Of course, the axis L1 of the tub of the collecting device 3 can also be parallel to the axis L2. The axis L1 makes an angle α of between 30 and 150 degrees with the longitudinal axis 111 of the cyclonic separating apparatus 1. Thus, the axis L3 of the handle in figure 1 may also be at an angle θ of between 30 and 150 degrees to the longitudinal axis 111 of the cyclonic separating apparatus 1.

Referring to fig. 1 and 6, the handheld cleaning device further comprises an outlet air filter unit 6 located downstream of the suction unit 4, and the outlet air filter unit 6 is located above the handle 7.

With continued reference to the handheld cleaning device shown in fig. 1 and 6, the bottom end surface of the collecting device 3 is flush with the side end surface of the handle 7 far from the main body 200 to form a supporting surface for supporting the handheld cleaning device, so that a user can conveniently place the handheld cleaning device when needed (such as when replacing a cleaning head), and the handheld cleaning device is not easy to topple over and is stably placed.

The bottom of the battery pack compartment containing the battery pack 8 may also be flush with the bottom of the collecting device 3, as shown in fig. 1. Further, as shown in fig. 1, the main body 200, the handle 7 and the battery compartment may enclose a closed holding space for the user to hold.

In order to further increase the ash collecting amount of the collecting device and reduce the ash pouring frequency of a user, an ash pressing component can be arranged in the collecting device. Specifically, referring to fig. 6, the handheld cleaning device further includes: an ash pressing assembly 10 disposed in the collecting device 3, the ash pressing assembly 10 being operable to move between a first position and a second position, wherein in the first position (as shown in fig. 10 and 14), the ash pressing assembly 10 engages the wall of the collecting chamber 38 of the collecting device to allow dust to freely enter the collecting chamber from the separating chamber; in a second position (e.g., the position shown in fig. 11, the position shown in fig. 15, the position shown in fig. 16, etc.), the dust compaction assembly 10 occupies the interior space of the collection chamber to exert a force on the dust in the collection chamber 38 to compress it. The addition of the ash compaction assembly 10 within the collection chamber 38 increases the amount of ash collected by the collection device and reduces the frequency with which the user dumps ash.

FIG. 10 shows a schematic view of the ash compaction assembly in a first position; FIG. 11 shows a schematic view of the ash compaction assembly in a second position; FIG. 12 illustrates a schematic view of the ash press assembly as it moves to an extreme position; FIG. 13 shows an exploded view of a collecting device provided with a dust pressing assembly; FIG. 14 shows a three-dimensional schematic view of the ash compaction assembly in a first position; FIG. 15 is a three-dimensional schematic view of a first state of the ash compacting assembly during compacting; FIG. 16 is a three-dimensional schematic view of a second state of the ash compacting assembly during ash compaction; FIG. 17 shows a schematic of the ash compaction assembly.

As shown in fig. 9 and 10, the hand-held cleaning device may further include: a driving member 101 for driving the dust pressing plate 100 of the dust pressing assembly 10 to move in the collecting cavity 38. Referring to the specific example shown in fig. 13, 14, 15, 16 and 17, the drive member 101 is a hand wrench disposed outside the collection chamber; a hand wrench is coupled to the dust pressing plate 100 of the dust pressing assembly 10 to move the dust pressing plate 100 within the collection chamber 38.

The ash pressing assembly 10 is rotatably connected to the wall of the collection chamber such that the ash pressing assembly 10 rotates between a first position and a second position. As shown in fig. 17, the ash pressing assembly 10 may specifically include: a rotating shaft 105 and an ash pressing plate 100, wherein a supporting seat 107 for accommodating the rotating shaft is arranged on the cavity wall of the collecting cavity 38 (namely, the barrel wall of the collecting device), and the rotating shaft 105 is connected with the end part of the ash pressing plate 100. The tub body of the collecting device 3 has a tub axis extending in the length direction, i.e. the axis L1 shown in fig. 1 is mentioned in the above; referring to fig. 10 to 16, the rotation shaft 105 is perpendicular to the tub axis (i.e., the axis L1), and is located on one side of the tub wall, such as in the middle of the tub wall in the length direction.

FIGS. 10 to 12 show schematic plan views of ash pressing assemblies provided in the tub of the collecting apparatus; figures 14 to 16 show a schematic view of the structure within the collecting chamber after removal of part of the chamber wall of the collecting chamber of the collecting device. As shown in FIGS. 10 and 14, the rotatable shaft is disposed on a first chamber wall 381 of the collection chamber 38, and in the first position, the ash plate 100 of the ash assembly 10 contacts the first chamber wall 381. The collection chamber 38 further includes a second chamber wall 382 opposite the first chamber wall 381; as shown in fig. 11 and 16, in the second position, the soot plate 100 of the soot assembly 10 at least partially contacts the second chamber wall 382. Referring to FIG. 6, the second chamber wall 382 is closer to the handle 7 than the first chamber wall 381.

Further, as shown in fig. 17, the handheld cleaning device further includes a return structure 106, and the return structure 106 is disposed between the manual wrench and the dust pressing plate 100; when external force is applied to the manual wrench, the manual wrench drives the dust pressing plate 100 to move from the first position to the second position so as to apply acting force on dust in the collection cavity, wherein the acting force is applied to the dust in the collection cavity from the top to the bottom of the collection cavity; when the external force on the manual wrench disappears, the dust pressing plate 100 returns from the second position to the first position under the action of the return structure. In one implementation, the return structure is a return spring disposed between the manual wrench and the dust pressing plate 100; during the process that the dust pressing plate 100 moves from the first position to the second position, the return spring generates deformation. For example, the return spring is a torsion spring, one end of the torsion spring is connected with the manual wrench, and the other end of the torsion spring is connected to the collection cavity. Through increasing return structure, the user need not to pull manual spanner and will press hawk 100 to rotate to the primary importance, avoids causing the ash pressing effect of pressing hawk 100 to descend because of the user forgets the operation with pressing hawk 100 return to the primary importance.

Or the driving piece is a driver; correspondingly, the handheld cleaning appliance also comprises a controller. The controller is connected with the driver and used for sending a control command to the driver to control the driver to provide power for the ash pressing plate when the suction unit is monitored to be in a non-working state.

Referring to a hand-held cleaning device as shown in fig. 11 or 16, the dust pressing plate 100 is operable to move within the collection chamber 38 to compress the volume occupied by the dust, and the dust pressing plate 100 remains in contact with the walls of the collection chamber 38 at all times during the movement. The ash plates remain in contact with the walls of the collection chamber 38 at all times during movement, which can help to increase ash efficiency. In practice, the profile of the surface of the dust pressing plate 100 of the dust pressing assembly 10 is similar to the cross section of the collecting cavity of the collecting device 3; during the movement, the dust pressing plate 100 of the dust pressing assembly is always in contact with the inner wall of the collecting device 3. For example, as shown in fig. 13 to 16, the cross section of the collecting chamber of the collecting device 3 is rectangular, and the plate surface of the corresponding dust pressing plate 100 may also be rectangular. The cross section of the collecting cavity of the collecting device is circular, and the plate surface of the corresponding dust pressing plate 100 is also circular. In order to keep the dust pressing plate 100 in contact with the inner wall of the collecting chamber of the collecting device 3 at all times, the dust pressing plate 10 can be a flexible pressing plate. Alternatively, the dust pressing plate 10 comprises at least two sections of rigid parts; adjacent rigid portions are connected by a flexible portion. As shown in fig. 17, the dust pressing plate comprises two rigid parts, and two

rigid parts

102 and 103 are connected through a flexible part 104. Or the dust pressing plate comprises a rigid part, and the edge of the rigid part is a flexible part.

Referring to the specific example shown in fig. 17, the dust pressing plate 100 includes a first rigid portion 102, a second rigid portion 103, and a flexible portion 104, and the flexible portion 104 connects the first rigid portion 102 and the second rigid portion 103. The rotation shaft 105 is located at an end of the first rigid portion 102, and the flexible portion 104 is located at the opposite end of the first rigid portion 102. The angle formed between the first rigid part 102 and the second rigid part 103 changes accordingly with the movement process.

Further, as shown in fig. 17, the widths K of the first rigid portion 102, the second rigid portion 103 and the flexible portion 104 are equal and equal to the width of the collection chamber 38. The length M1 of the first rigid part 102 is less than the length between the opposing walls of the collection chamber 38, and the sum of the lengths of the first and second rigid parts 102 and 103 (i.e., the sum of M1 and M2) is greater than the length between the opposing walls of the collection chamber 38.

The length of the first rigid portion 102 may be equal to the length of the second rigid portion 103; alternatively, the length of the first rigid portion 102 is greater than the length of the second rigid portion 103; alternatively, the length of the first rigid portion 102 is smaller than the length of the second rigid portion 103. Specifically, the ratio of the length of the first rigid portion 102 to the length of the second rigid portion may be 0.5 to 2; that is, M1/M2 is 0.5 to 2.

The working and ash dumping process of the handheld cleaning device provided by the embodiment of the application is described below with reference to specific application scenarios:

working scene

When a user needs to use the handheld cleaning equipment, the fan assembly (namely the motor and the impeller) is started to generate suction air flow by manually touching the switch control, dirty air flow generated by sweeping through the floor brush flows into the separation barrel through the dust inlet through the air inlet duct, and then the dirty air flow is forced to travel along a spiral path inside the wall of the separation barrel due to the tangential arrangement of the dust inlet. Larger dirt and dust particles are separated by cyclonic motion about the wall. These particles enter the barrel of the collecting device through the dust outlet and some fine dust or hair may be trapped in the separating tub of the cyclonic separating apparatus. The sucked air separated from the dust enters a negative pressure cavity of the fan assembly in the main body through clean air flow obtained after the sucked air is filtered by the air inlet filtering unit and is discharged after being filtered by the air outlet filtering unit.

Ash pressing scene

When a user finds that dust in the barrel body of the collecting device is more in the using process, the switch control can be turned off (for example, the switch control is loosened or the poking piece pressed on the switch control is poked). After the switch control is closed, the battery pack stops supplying power, and the fan assembly stops working. The manual spanner in user's accessible collection device outside controls the pressure grey subassembly activity in the collection device, compresses the dust in the collection device, improves collection device's ash storage ability to reduce the frequency of falling the ash.

Graying scene

When the collecting apparatus is full of dust, the user can release the catch to allow one side of the cover to be removed from the collecting apparatus, and the dust and dirt in the collecting apparatus can be poured out of the dust pouring outlet. In the ash pouring process, a user can control the ash pressing component in the collecting device to move through a manual wrench outside the collecting device, and when the ash pressing component moves to the bottom of the collecting cavity in the collecting cavity, the ash pressing component partially exceeds the ash pouring opening so as to push out dust in the collecting device.

Clean intake air filter unit scenario

The user scrapes off the dust attached to the air inlet filter unit through the air inlet filter unit of the pull separating device and the scraping strip ring on the separating barrel. The scraped dust falls into the separation tub. The user can pull down the separating barrel from the installation main body, and the dust in the separating barrel can be cleared out.

Fig. 22 to 26 are schematic structural diagrams of a handheld cleaning device provided by another embodiment of the present application. The handheld cleaning device provided by the present embodiment is different from the above embodiments in appearance in that: the collecting means located outside the cyclonic separating apparatus is eliminated. Specifically, referring to fig. 22, 23 and 24, the inlet duct 2 has an axis 21 extending through the inlet opening, the axis 21 extending through the battery pack 8 and the handle 7. The collecting device is removed, and although the dust collecting amount is reduced, the whole machine is more portable and convenient to use.

In this embodiment, since no collecting device is provided, the separating tub 11 of the cyclone separating apparatus 1 functions to collect ash. The communication port 27 of the intake duct 2 may be provided at a side of the separation tub 11 adjacent to the main body 200. For example, as shown in fig. 23, the cyclonic separating apparatus comprises a separating tub 11, the separating tub 11 having a first end 112 remote from the main body 200 and a second end 113 connected to the main body 200, and a tub wall located between the first end 112 and the second end 113; the air inlet duct 2 is arranged by being attached to the outer side of the barrel wall.

For example, as shown in fig. 23, the separation tub 11 is a cylindrical tub; a concave arc part (not shown in the figure) arranged on the outer wall of the cylindrical barrel is formed on the outer wall of the air inlet duct 2; the concave arc part is provided with a communicating port 27 which penetrates through the air duct wall of the air inlet duct and is communicated with the air inlet duct 2; a dust inlet 114 is arranged at the position of the separation barrel 11 corresponding to the communication port 27; the air inlet duct 2 is communicated with the separation barrel 11 through the communication port 27 and the dust inlet 114. Wherein the dust inlet 114 may be disposed on the tub wall near the second end 113.

In one implementation, the main body 200 may further include a battery pack compartment 15 for accommodating the battery pack 8; one end of the air inlet duct 2 opposite to the air inlet is connected to the outer wall of the battery pack chamber 15.

Referring to fig. 22, the inlet duct 2 may have three sections, a first section 301 extending beyond the first end 232 of the separation tub 11, a second section 303 connected to the battery pack compartment 15, and a third section 302 located between the first section 301 and the second section 303; the outer dimensions of the first section 301, the third section 302 and the second section 303 are gradually increased. The reason why the outer contour dimension of the first section is smaller than that of the third section is that the first section is required to be connected with a cleaning head (such as a floor brush), and after the cleaning head is connected, the outer contour surface of the cleaning head can be flush with the outer contour surface of the third section, so that the outer contour of the handheld cleaning equipment is more regular and attractive in appearance. The second section has the largest outer contour size and aims to form a communication port capable of guiding airflow to enter the separation barrel tangentially.

Referring to fig. 22, 23 and 24, the first end 113 of the separating tub 11 is provided with an ash pouring port and a bottom cover 17 for movably opening the ash pouring port; an air inlet filtering unit 12 is also arranged in the separation barrel 11; when the bottom cover 17 is buckled at the dust pouring port, the contact part of the bottom cover 17 and the air inlet filtering unit 12 is sealed. For example, in the example shown in fig. 25, the end of the intake air filtering unit contacting the bottom cover 17 is provided with a sealing strip 241, and when the bottom cover 21 is fastened to the dust-discharging buckle, the sealing strip 241 deforms to cling to the bottom cover 17 for sealing. As shown in fig. 22 and 24, an opening and closing trigger 18 is disposed at a connection portion of the air inlet duct and the separation barrel 11, and a fastening mechanism (not shown) is disposed between the bottom cover 17 and the separation barrel 11. When the opening and closing trigger part 18 is touched, the clamping mechanism acts one side of the bottom cover 17 to separate from the separating barrel, and the ash pouring port is opened; the user presses the bottom cover 17 to buckle the bottom cover 17 at the ash pouring port of the separating barrel 11, and the bottom cover 17 is buckled at the ash pouring port through the buckling mechanism to seal the ash pouring port.

Referring to fig. 26, the main body 200 is further provided with a release member 251; a dismounting mechanism 252 is arranged between the main body 200 and the separation barrel 11; when the release 251 is touched, the detaching mechanism 252 is operated to detach the separating tub 11 from the main body 200. Specifically, the release member 251 may be a resilient button, as shown in fig. 26. The disassembly and assembly mechanism 252 may include: a first part 1021 and a second part 1022. Wherein, the first part 1021 is a rotating piece, which has a driven part 10211 and an engaging part 10212 linked with the elastic part; the second part 1022 is provided with a fastening portion cooperating with the fastening portion 10212. When the elastic button is pressed by external pressure, the elastic button moves downwards and drives the driven part 10211 to move, the first part 1021 rotates around the self rotating shaft 10213, so that the fastening part 10212 connected with the fastening part tilts and then is separated from the fastening part, and at the moment, the separation barrel 11 is separated from the main body 200.

The operation and ash discharge process of the handheld cleaning device provided in fig. 22 to 26 are described below with reference to specific application scenarios:

working scene

When a user needs to use the handheld cleaning equipment, the fan assembly (namely the motor and the impeller) is started to generate suction air flow by manually touching the switch control, dirty air flow generated by sweeping through the floor brush flows into the separation barrel through the dust inlet through the air inlet duct, and then the dirty air flow is forced to travel along a spiral path inside the wall of the separation barrel due to the tangential arrangement of the dust inlet. Larger dirt and dust particles are separated by cyclonic motion about the wall. These particles remain in the separating vessel of the cyclonic separating apparatus. The sucked air separated from the dust enters a negative pressure cavity of the fan assembly through clean air flow obtained after the sucked air flow is filtered by the air inlet filtering unit and then is discharged after being filtered by the air outlet filtering unit.

Graying scene

When the dust in the separation barrel is full, a user can open the bottom cover on the separation barrel and pour out the dust in the separation barrel. After the dust is poured out, the bottom cover can be covered by a user, and the bottom cover is sealed at the contact position with the air inlet filtering unit.

Clean scene of air inlet filtering unit

When objects which are difficult to clean, such as hair, are wound on the air inlet filtering unit, a user can press the release piece arranged on the main body 200; the action of a dismounting mechanism arranged between the main body and the separating barrel enables the separating barrel to be separated from the main body. The user takes off the separating barrel, and the air inlet filter unit exposes, and the user can clean it. After cleaning, the separating barrel is put back to the original position, and the separating barrel is locked on the main body by the disassembling and assembling mechanism, thus completing the installation.
