[0099] Reference is made toFigures 1-3 In an embodiment, the body 10 is used in a horizontal cleaning device, the horizontal cleaning device comprises a holding assembly 8100, a floor brush assembly 8200 and a flexible tube 8300, one end of the holding assembly 8100 is connected with the floor brush assembly 8200, the other end of the holding assembly 8100 is connected with the flexible tube 8300, and one end of the flexible tube 8300 away from the holding assembly 8100 is connected with the body 10. The body 10 has a roller at one end close to the surface to be cleaned along the second direction. In the working state, the holding assembly 8100 is configured to be operable to move on the surface to be cleaned, so as to drive the body 10 to move on the surface to be cleaned through the roller by the flexible tube 8300.

[0100] In an embodiment, the body 10 comprises a shell 4000, a filter structure 100, a negative pressure motor assembly 200, a power supply assembly (in an embodiment, the power supply assembly is a battery pack assembly 5100) and a handle assembly 6000 installed on the shell 4000. The negative pressure motor assembly 200, the power supply assembly and the handle assembly 6000 are all located on one side of the filter structure 100 along the first direction, and the negative pressure motor assembly 200 has a negative pressure motor air inlet 3100 at one end close to the filter structure 100 along the first direction. The power supply assembly is located on one side of the negative pressure motor assembly 200 away from the surface to be cleaned along the second direction, and the handle assembly 6000 is located on one side of the power supply assembly away from the negative pressure motor assembly 200 along the second direction. The first direction is the axial direction of the negative pressure motor 3000 in the negative pressure motor assembly 200, the second direction is the height direction of the body 10, and the first direction is perpendicular to the second direction.

[0101] Generally, the airflow in the negative pressure motor 3000 flows in a direction substantially parallel to the axial direction thereof. In the above embodiment, since the negative pressure motor assembly 200 is located on the side of the filtering structure 100 along the first direction, and the negative pressure motor air inlet 3100 is located on the end of the negative pressure motor assembly 200 along the first direction close to the filtering structure 100, the airflow flowing out of the filtering structure 100 will flow in a direction substantially along the first direction towards the negative pressure motor assembly 200, directly to the negative pressure motor air inlet 3100, and then flow into the negative pressure motor 3000 in a direction substantially along the first direction from the negative pressure motor air inlet 3100. It can be seen that after flowing out of the filtering structure 100, the airflow can directly flow into the negative pressure motor 3000 without a large-angle turn, thus reducing the air resistance and making the airflow flow more smoothly with less fluid loss. In addition, the second direction is the height direction of the machine body 10, and the first direction is perpendicular to the second direction, i.e., in the use state, the first direction is the horizontal direction. The negative pressure motor assembly 200, the power supply assembly, and the handle assembly 6000 are all located on the side of the filtering structure 100 along the first direction, i.e., all located on the side of the filtering structure 100 along the horizontal direction. The power supply assembly is located on the side of the negative pressure motor assembly 200 along the second direction away from the surface to be cleaned, and the handle assembly 6000 is located on the side of the power supply assembly along the second direction away from the negative pressure motor assembly 200, i.e., in the use state, the power supply assembly is located above the negative pressure motor assembly 200, and the handle assembly 6000 is located above the power supply assembly. The axial direction of the negative pressure motor 3000 is the first direction, i.e., the negative pressure motor 3000 is "lying down", which can minimize the space occupied by the negative pressure motor assembly 200 in the second direction. Since the power supply assembly is located above the negative pressure motor assembly 200, and the handle assembly 6000 is located above the power supply assembly, the space saved in the second direction after the negative pressure motor 3000 is "lying down" can be better utilized, making the structure distribution in the machine body 10 more compact and the space occupied by the machine body 10 smaller. In addition, since the negative pressure motor assembly 200 is a relatively heavy structure in the machine body 10, locating it below the handle assembly 6000 can concentrate most of the weight of the machine body 10 below the handle assembly 6000, thus making it easier for the user to lift the handle assembly 6000.

[0102] Figures 1-3 In the perspective view, the second direction is the up-down direction, the first direction is the left-right direction, and the third direction is the front-back direction. In the use state of the horizontal cleaning device, the second direction is the up-down direction.

[0103] Referring to Figures 3-6 In some embodiments, the handle assembly 6000 and the power supply assembly at least partially overlap along the third direction, and the size of the handle assembly 6000 along the third direction is greater than the size of the power supply assembly along the third direction. In this way, the user can move or store the horizontal cleaning device at a distance by lifting the handle assembly 6000 more easily.

[0104] Referring to Figures 3-6 In some embodiments, the power supply assembly is a battery pack assembly 5100, and the casing 4000 has a battery mounting port 4330 at one end thereof along the first direction away from the filter structure 100, and the battery pack assembly 5100 is detachably mounted in the casing 4000 through the battery mounting port 4330.

[0105] Specifically, the casing 4000 comprises a casing base 4100 and a casing top cover 4200 fixedly connected, and the casing top cover 4200 is fixed to one end of the casing base 4100 along the second direction away from the surface to be cleaned. The battery mounting port 4330 is formed between the one end of the casing base 4100 and the casing top cover 4200 along the first direction away from the filter structure 100. The battery pack assembly 5100 can be mounted and detached through the battery mounting port 4330, so as to facilitate its maintenance, replacement and charging.

[0106] In some embodiments, the part of the battery pack assembly 5100 exposed to the battery mounting port 4330 is provided with a charging port. Since the charging port is exposed to the battery mounting port 4330, the user can conveniently charge the battery pack assembly 5100 through the charging port.

[0107] In other embodiments, the power supply assembly is a power cord, and the power supply is performed by externally connecting a power source through the power cord. In subsequent embodiments, the power supply assembly is mainly taken as the battery pack assembly 5100.

[0108] Referring to Figures 4-5 In some embodiments, the one end of the battery pack assembly 5100 along the first direction away from the filter structure 100 does not exceed the one end of the casing 4000 along the first direction away from the filter structure 100. That is, the battery pack assembly 5100 is completely installed in the casing 4000 through the battery mounting port 4330, and the outer end thereof does not protrude from the end face of the casing 4000. In this way, the battery pack assembly 5100 can be protected through the outer end of the casing 4000, so as to be less likely to be damaged by collision, and the risk of being detached and falling due to external force touching can be reduced.

[0109] Referring to Figures 3-7 In some embodiments, the casing 4000 is provided with a battery compartment 5200 connected thereto, the battery pack assembly 5100 is detachably mounted in the battery compartment 5200 through the battery mounting port 4330, and the battery pack assembly 5100 and the battery compartment 5200 are slidingly matched along the first direction.

[0110] Specifically, the battery compartment 5200 is fixedly installed in the casing 4000, and the battery compartment 5200 has a battery compartment opening 5240 in communication with the battery installation opening 4330 at one end thereof facing away from the filtering structure 100 in the first direction, the battery compartment opening 5240 being used for the battery pack assembly 5100 to enter and exit, and the battery pack assembly 5100 is detachably installed in the battery compartment 5200 in sequence through the battery installation opening 4330 and the battery compartment opening 5240. When the battery pack assembly 5100 is installed in the battery compartment 5200 without being position-locked, the battery pack assembly 5100 is slidingly fitted in the battery compartment 5200 in the first direction. In this way, the battery pack assembly 5100 can be pushed in or pulled out to complete the disassembly and assembly, and the operation is more convenient.

[0111] Referring to Figures 7-9 , and Figure 11 In some embodiments, the inner wall of the compartment body of the battery compartment 5200 is configured with a compartment body sliding groove 5210 extending in the first direction, and the battery pack assembly 5100 is provided with a sliding plate 5110 extending in the first direction, the sliding plate 5110 being slidingly installed in the compartment body sliding groove 5210.

[0112] Specifically, the inner wall of the compartment body of the battery compartment 5200 is configured with two protruding ribs 5211 extending in the first direction and arranged at intervals, and the compartment body sliding groove 5210 is formed between the two protruding ribs 5211. The battery pack assembly 5100 is provided with a battery pack shell 5140 wrapped around the battery pack 5150, and the outer wall of the battery pack shell 5140 is provided with the sliding plate 5110. When the battery pack assembly 5100 is pushed or pulled, the sliding plate 5110 slides in the first direction in the compartment body sliding groove 5210 to guide and limit the position, so that the disassembly and assembly process of the battery pack assembly 5100 is more stable.

[0113] In other embodiments, the positions of the sliding plate 5110 and the compartment body sliding groove 5210 can also be interchanged, or other conventional sliding fitting structures can be selected.

[0114] Referring to Figures 7-9 , and Figure 11 In some embodiments, one of the battery compartment 5200 and the battery pack assembly 5100 is provided with a battery pack locking groove 5220, the other is provided with a battery pack locking block 5120 elastically clamped into the battery pack locking groove 5220, and the battery pack assembly 5100 is provided with a battery pack release button 5130 connected to the battery pack locking block 5120, the battery pack release button 5130 being configured to be operable to be pressed to drive the battery pack locking block 5120 to exit the battery pack locking groove 5220.

[0115] In the embodiment shown in the drawings, the battery compartment 5200 is provided with a battery pack locking groove 5220, the battery pack assembly 5100 is provided with a battery pack locking block 5120 elastically clamped into the battery pack locking groove 5220, and the battery pack assembly 5100 is provided with a battery pack release button 5130 connected to the battery pack locking block 5120. Specifically, the battery pack locking groove 5220 is formed in the compartment wall of the battery compartment 5200, the battery pack locking block 5120 and the battery pack release button 5130 are integrally formed or fixedly connected, and the battery pack release button 5130 and the battery pack shell 5140 are elastically connected through a battery pack locking elastic member 5160. The battery pack locking elastic member 5160 is used to apply an elastic force to the battery pack locking block 5120 through the battery pack release button 5130, so that the battery pack locking block 5120 is clamped into the battery pack locking groove 5220. When the battery pack release button 5130 is pressed, the battery pack locking block 5120 is driven to overcome the elastic force of the battery pack locking elastic member 5160 and escape from the battery pack locking groove 5220. Through the above locking structure, the battery pack assembly 5100 can be firmly and stably locked in the battery compartment 5200, thereby realizing stable power supply, and when the battery pack assembly 5100 needs to be disassembled, quick disassembly can be realized, and the operation is more convenient and fast.

[0116] Referring to Figure 7 , Figure 8 , Figure 10 and Figure 11 In some embodiments, the machine body 10 includes a circuit board 5300 mounted in the machine shell 4000, the circuit board 5300 includes a board body 5310 and a coupler 5320 connected to each other, the board body 5310 is located outside the battery compartment 5200, and the coupler 5320 penetrates through the compartment wall of the battery compartment 5200 and is in contact and conduction with the battery pack assembly 5100.

[0117] Specifically, the board body 5310 of the circuit board 5300 is fixedly mounted on the outer wall of the battery compartment 5200, and the coupler 5320 protrudes from the board body 5310. The battery compartment 5200 is provided with a through coupler through hole 5230, the coupler 5320 penetrates through the coupler through hole 5230 and extends into the inside of the battery compartment 5200, and is in contact and conduction with the battery pack assembly 5100 mounted in the battery compartment 5200.

[0118] Preferably, in some embodiments, the circuit board 5300 includes a flexible coupler cap 5330 connected to the board body 5310 and sleeved outside the coupler 5320, and the flexible coupler cap 5330 is inserted into the coupler through hole 5230.

[0119] The flexible coupler cap 5330 is made of flexible materials such as silica gel or rubber, which is inserted into the coupler through hole 5230 and is in interference fit with the coupler through hole 5230, thereby protecting the coupler 5320 from being damaged by collision.

[0120] Referring toFigure 10 and Figure 11 In some embodiments, the flexible coupler cap 5330 has a protruding brim 5331 at the end near the circuit board 5300, and the brim 5331 blocks the end wall of the coupler through hole 5230 near the end of the circuit board 5300.

[0121] Specifically, from the perspective of the attached drawings, the top of the flexible coupler cap 5330 has a protruding brim 5331, which blocks the top end wall of the coupler through hole 5230. Thus, the brim 5331 blocking the end wall of the coupler through hole 5230 prevents the flexible coupler cap 5330 from falling downwards. Furthermore, it provides a good sealing effect at the coupler through hole 5230, preventing dust from reaching the surface of the circuit board 5300 and causing damage when the battery pack assembly 5100 is not installed.

[0122] See Figure 3 , Figure 7 and Figure 11 In some embodiments, the size of the battery compartment 5240 gradually increases in the direction along the first direction and away from the filter structure 100. This arrangement allows for a larger inlet size of the battery compartment 5240, thereby facilitating the user's installation and removal of the battery pack assembly 5100 from this location.

[0123] Furthermore, in some embodiments, in the orientation along the first direction and away from the filter structure 100, the battery compartment 5200 is inclined toward the negative pressure motor assembly 200 along the second direction near the compartment wall of the negative pressure motor assembly 200.

[0124] Specifically, in Figure 7 From this perspective, the bottom wall of the battery compartment 5200 slopes downwards. Users can press the battery pack release button 5130 with their thumb while simultaneously using their other four fingers to lift the battery pack assembly 5100 from the bottom for disassembly and assembly; this can be easily accomplished with one hand, making the operation quite convenient. Except for the bottom wall, no other area of ​​the battery compartment 5200 is designed to extend at an angle, thus minimizing the size of the battery compartment 5200 and reducing the space it occupies within the housing 4000. Of course, in other embodiments, the battery compartment opening 5240 can also be designed as a flared shape, smaller on the inside and larger on the outside.

[0125] See Figure 3 , Figure 4 and Figure 6In some embodiments, the casing 4000 comprises a grid plate 4110 that separates the inner cavity of the casing 4000 into a first installation cavity 4310 and a second installation cavity 4320 arranged along a first direction, and the grid plate 4110 has a wind passage 4111 that communicates the first installation cavity 4310 and the second installation cavity 4320, the filter structure 100 is installed in the first installation cavity 4310, and the negative pressure motor assembly 200 and the power supply assembly (the battery pack assembly 5100) are installed in the second installation cavity 4320.

[0126] Specifically, the casing base 4100 comprises a grid plate 4110 that is hollow to form the wind passage 4111. By arranging the grid plate 4110, the airflow can be guided and concentrated, so that the airflow discharged from the filter structure 100 to the first installation cavity 4310 can more concentratedly pass through the wind passage 4111 into the second installation cavity 4320, and then more concentratedly flow into the negative pressure motor assembly 200, so as to reduce fluid loss and improve suction efficiency.

[0127] Referring to Figure 3 、 Figure 4 and Figure 6 In some embodiments, the first installation cavity 4310 has a first suction port 4340 for fluid inflow at an end thereof away from the second installation cavity 4320 along the first direction, the filter structure 100 has a first ash inlet 1111 that communicates with the first suction port 4340 at an end thereof away from the second installation cavity 4320 along the first direction, and the filter structure 100 has a first air outlet passage 1113 that communicates with the wind passage 4111 at an end thereof close to the second installation cavity 4320 along the first direction.

[0128] Specifically, the negative pressure motor assembly 200 comprises a motor cover structure 2000 and a negative pressure motor 300 installed in the motor cover structure 2000, and the specific structure of the motor cover structure 2000 is described in subsequent embodiments. The negative pressure motor 300 provides suction force, so that the external airflow with garbage is sucked into the casing 4000 through the first suction port 4340, and then enters the filter structure 100 through the first ash inlet 1111 to be filtered and separated, the garbage is left in the filter structure 100, the clean airflow is discharged from the first air outlet passage 1113 to the first installation cavity 4310, and then is sucked into the second installation cavity 4320 from the wind passage 4111, is sucked into the motor from the negative pressure motor air inlet 3100 of the negative pressure motor 3000, and is discharged to the external environment from the first outlet 4350 formed in the casing 4000 after being discharged from the negative pressure motor 3000.

[0129] In the embodiment shown in the drawings, the filter structure 100 is a dust cup structure 1000. In other embodiments, the filter structure 100 can also be a filter bag. In the following, the filter structure 100 will mainly be taken as an example of the dust cup structure 1000. The specific structure inside the dust cup structure 1000 will be described in subsequent embodiments.

[0130] Referring to Figure 3 , Figure 4 and Figure 6 In some embodiments, the housing 4000 has a first outlet 4350 at one end along a third direction, which is in communication with the second mounting cavity 4320 and is used for discharging fluid, and the second hepa filter 5410 and the aromatherapy piece 5420 are mounted at the first outlet 4350, wherein the third direction is perpendicular to the first direction and the second direction.

[0131] Specifically, the first outlet 4350 is located opposite the air outlet of the negative pressure motor assembly 200, so as to facilitate smooth discharge of airflow. In the above embodiment, by mounting the second hepa filter 5410 at the first outlet 4350, the airflow can be filtered again before it flows out to the external environment, further reducing the probability of dust discharge. By mounting the aromatherapy piece 5420 at the first outlet 4350, the discharged airflow can have a fragrance, so as to purify the external environment and improve the use experience. In other embodiments, the first outlet 4350 can also be provided at both ends of the housing 4000 along the third direction, and the second hepa filter 5410 and the aromatherapy piece 5420 are mounted at both first outlets 4350.

When the filter structure 100 (dust cup structure 1000) is mounted, the bottom cover positioning protrusion 4311 is inserted into the bottom cover positioning groove 1520, and positioning can be performed to facilitate quick installation. In other embodiments, the positions of the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520 can be interchanged.

[0136] Preferably, a plurality of sets of matched bottom cover positioning protrusions 4311 and bottom cover positioning grooves 1520 are provided to further optimize the limiting effect and limit the rotation and movement of the filter structure 100 (dust cup structure 1000) in the horizontal plane after being installed in the first mounting cavity 4310.

[0137] Referring to Figure 4 , Figure 12 and Figure 30 In some embodiments, one of the cavity wall of the first mounting cavity 4310 and the filter structure 100 is provided with the cup machine hook 1131, and the other is provided with the cup machine positioning groove 4312, and the cup machine hook 1131 is hung in the cup machine positioning groove 4312.

[0138] In the embodiment shown in the drawings, the cavity wall of the first mounting cavity 4310 is provided with the cup machine positioning groove 4312, and the filter structure 100 (dust cup structure 1000) is provided with the cup machine hook 1131, and the cup machine hook 1131 is hung in the cup machine positioning groove 4312, which can limit the movement of the filter structure 100 (dust cup structure 1000) in the horizontal plane after being installed in the first mounting cavity 4310 to enhance the limiting effect. In other embodiments, the positions of the cup machine hook 1131 and the cup machine positioning groove 4312 can also be interchanged.

[0139] Preferably, a plurality of sets of matched cup machine hooks 1131 and cup machine positioning grooves 4312 are provided to further optimize the limiting effect.

[0140] Referring to Figure 4 , Figure 12 and Figure 30In some embodiments, the bottom cover positioning groove 1520 is arranged at one end of the filter structure 100 along the second direction close to the surface to be cleaned, the cup machine hook 1131 is arranged at one end of the filter structure 100 along the first direction close to the second mounting cavity 4320, and in the second direction, the cup machine hook 1131 is located at the side of the bottom cover positioning groove 1520 away from the surface to be cleaned.

[0141] Specifically, the bottom cover positioning groove 1520 is arranged at the bottom of the filter structure 100 (dust cup structure 1000), and the cup machine hook 1131 is arranged at the side of the filter structure 100 (dust cup structure 1000) close to the top end. In this way, the cup machine hook 1131 and the cup machine positioning groove 4312, and the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520 can be used to position the top end and the bottom end of the filter structure 100 (dust cup structure 1000), optimize the positioning effect, and make the filter structure 100 (dust cup structure 1000) more stable after installation.

[0142] Referring to Figure 4 , Figure 12 and Figure 27 In some embodiments, one of the cavity wall of the first mounting cavity 4310 and the filter structure 100 is provided with the upper cover clamping groove 4313, the other is provided with the upper cover protrusion 1410 elastically clamped into the upper cover clamping groove 4313, and the upper cover rotating buckle 1420 connected to the upper cover protrusion 1410 is configured to be operable to drive the upper cover protrusion 1410 to exit the upper cover clamping groove 4313.

[0144] Specifically, the dust cup structure 1000 comprises a dust cup upper cover 1400, and an elastic member is connected between the dust cup upper cover 1400 and a dust cup upper cover protrusion 1410, and the elastic force of the elastic member enables the dust cup upper cover protrusion 1410 to be elastically clamped into the upper cover clamping groove 4313. The dust cup upper cover 1400 is rotationally connected with an upper cover rotating buckle 1420, and by rotating the upper cover rotating buckle 1420, the upper cover rotating buckle 1420 can abut against the dust cup upper cover protrusion 1410 and push the dust cup upper cover protrusion 1410 out of the upper cover clamping groove 4313. For example, the user holds the upper cover rotating buckle 1420 and rotates it clockwise, so that the upper cover rotating buckle 1420 pushes the dust cup upper cover protrusion 1410 to move away from the upper cover clamping groove 4313 until the dust cup upper cover protrusion 1410 is separated from the upper cover clamping groove 4313; then the user lifts the dust cup structure 1000 by using the dust cup handle 1430, so that the dust cup structure 1000 can be completely separated from the first installation cavity 4310. When installing, the user holds the upper cover rotating buckle 1420, and after the dust cup structure 1000 is placed into the first installation cavity 4310, the user releases the upper cover rotating buckle 1420, and the dust cup upper cover protrusion 1410 can be clamped into the upper cover clamping groove 4313 under the elastic force of the elastic member, so as to complete the locking.

[0145] Referring to Figure 1 、 Figure 5 and Figure 12 In some embodiments, the shell 4000 is provided with a hanging groove 4210 for hanging the cleaning module 20.

[0146] Specifically, the hanging groove 4210 is arranged at one end of the shell top cover 4200 away from the filter structure 100 (the dust cup structure 1000) in the first direction, and the holding assembly 8100 of the cleaning module 20 can be hung on the hanging groove 4210 after the horizontal cleaning device is used, so as to facilitate storage and improve the stability of the entire device.

[0147] As described above, in the working state, the holding assembly 8100 is configured to be operable to move on the surface to be cleaned, so as to drive the body 10 to move on the surface to be cleaned through the flexible pipe 8300 and the rollers. However, in the non-working state, when the horizontal cleaning device is moved at a long distance, the holding assembly 8100 cannot be used to drive the body 10 to move, because the surface to be cleaned can be scratched during the long distance movement. At this time, the user needs to hold the holding assembly 8100 with one hand and hold the handle assembly 6000 in the body 10 with the other hand to move the horizontal cleaning device, or hang the holding assembly 8100 on the hanging groove 4210 and then move the horizontal cleaning device as a whole.

[0148] Referring to Figure 1In an embodiment of the present application, the horizontal cleaning device comprises the machine body 10 in any of the above embodiments, and further comprises a cleaning module 20, which comprises a holding assembly 8100, a floor brush assembly 8200, and a flexible pipe 8300.

The floor brush assembly 8200 is aligned with the area to be cleaned. The suction force is provided by the negative pressure motor 2000 in the machine body 10. The external airflow entrains the garbage and sucks it into the suction port of the floor brush assembly 8200. The garbage is sequentially filtered by the holding assembly 8100 and the flexible pipe 8300, and then enters the filtering structure 100 in the machine body 10 for filtering. Then, the garbage is discharged from the machine body 10 after flowing through the negative pressure motor 2000.

[0150] Referring to Figure 1 In some embodiments, the holding assembly 8100 comprises a holding handle 8110, and an extension rod 8120 arranged between the holding handle 8110 and the floor brush assembly 8200. The extension rod 8120 is detachably connected to the floor brush assembly 8200 and / or the holding handle 8110.

[0151] Through the detachable connection between the extension rod 8120 and the floor brush assembly 8200, the floor brush assembly 8200 can be conveniently detached from the holding assembly 8100 for maintenance and replacement. Through the detachable connection between the extension rod 8120 and the holding handle 8110, the extension rod 8120 and the floor brush assembly 8200 can be conveniently detached from the holding handle 8110 as a whole for maintenance and replacement.

[0152] Preferably, the extension rod 8120 can be arranged as a telescopic rod, so as to be adjusted according to the use requirements of the user. Referring to Figure 1 and Figure 13 In some embodiments, the end of the holding handle 8110 close to the extension rod 8120 is rotationally connected with a local brush 8111. The local brush 8111 is small in size, and is suitable for cleaning some small gaps and corners. The horizontal cleaning device can have two cleaning modes. In one mode, the local brush 8111 is rotated to the Figure 1 position for storage, and the extension rod 8120 and the floor brush assembly 8200 are mounted on the holding handle 8110. The floor brush assembly 8200 is used for cleaning a large area of the floor or carpet. In the other mode, the extension rod 8120 and the floor brush assembly 8200 are detached from the holding handle 8110, and the local brush 8111 is rotated to the Figure 13In the shown position, some small gaps and corners are cleaned using the local brush 8111. In this way, the use scenarios of the horizontal cleaning device can be made more extensive.

Specifically, the floor brush lock 8210 and the floor brush button 8220 are integrally formed or fixedly connected, and at least one of the two is provided with a resilient member between the shell and other components of the floor brush assembly 8200. The resilient member elastically clamps the floor brush lock 8210 into the floor brush lock cavity 8123 through the resilience of the resilient member. When the floor brush button 8220 is pressed, the resilience of the resilient member can be overcome, and the floor brush lock 8210 can be pulled out of the floor brush lock cavity 8123.

[0157] Referring to Figures 16-17 In some embodiments, one of the holding handle 8110 and the extension rod 8120 is provided with a handle lock cavity 8112, the other is provided with a handle lock 8124 elastically clamped into the handle lock cavity 8112, and a handle button 8125 connected to the handle lock 8124, the handle button 8125 is configured to be operatively pressed to drive the handle lock 8124 to exit the handle lock cavity 8112.

[0158] In the embodiment shown in the drawings, the holding handle 8110 is provided with a handle locking cavity 8112, the extension rod 8120 is provided with a handle lock 8124 elastically clamped into the handle locking cavity 8112, and the handle handle button 8125 is connected to the handle lock 8124. The specific cooperation structure is basically the same as that of the mop lock 8210, the mop button 8220 and the mop lock cavity 8123, and will not be described here.

[0159] Referring to Figure 18 In some embodiments, the extension rod 8120 has a fluid passage 8126 and a wire passage 8127 separated from each other. Specifically, the fluid passage 8126 and the wire passage 8127 both extend along the length direction of the extension rod 8120. The fluid passage 8126 is used for the airflow carrying garbage to pass through, and the wire passage 8127 is used for the cable to pass through. By providing the separated fluid passage 8126 and wire passage 8127, the cable can be protected and is not easy to be damaged by being scraped by garbage and airflow.

[0160] Referring to Figure 20 In some embodiments, the flexible tube 8300 is provided, at the end away from the holding assembly 8100, with a third electrical connection part 8311 for plugging and conducting with the body 10, the third electrical connection part 8311 being a pin or a slot. In the embodiment shown in the drawings, the third electrical connection part 8311 is a pin, and the body 10 is provided with a slot for plugging and cooperating with the first electrical connection part 8121. Through the third electrical connection part 8311, the circuit conduction between the cleaning module 20 and the body 10 can be realized.

[0161] Referring to Figures 1-2 In an embodiment, the horizontal cleaning device provided by the present application comprises a body 10 and a cleaning module 20. The cleaning module 20 comprises a holding assembly 8100, a mop assembly 8200 and a flexible tube 8300. One end of the holding assembly 8100 is connected to the mop assembly 8200, and the other end is connected to the flexible tube 8300. The end of the flexible tube 8300 away from the holding assembly 8100 is connected to the body 10. The body 10 is provided with a display area 9000 for displaying target parameters. The distance between the display area 9000 and the surface to be cleaned along the second direction is greater than the distance between other areas of the body 10 and the surface to be cleaned along the second direction, wherein the second direction is the height direction of the body 10.

[0162] In the above embodiments, the display area 9000 is arranged on the body 10. In use, the body 10 is usually placed on the surface to be cleaned. The overall height of the body 10 is lower than that of the cleaning module 20. The user can directly lower his head to observe the display area 9000 in time. On this basis, in the second direction, the distance between the display area 9000 and the surface to be cleaned is greater than the distance between other areas of the body 10 and the surface to be cleaned. That is, the display area 9000 is located at the position with the greatest distance between the body 10 and the surface to be cleaned. That is, the display area 9000 is located at the position with the greatest height on the body 10. Such an arrangement can prevent the display area 9000 from being blocked by other structures in the body 10, so that there is no visual blind area. After the user lowers his head, he can easily observe the display area 9000 at any angle, so that he can learn the current operating status of the device in time. In addition, since the display area 9000 is arranged on the body 10 rather than the holding assembly 8100, it is not necessary to arrange a wire for electrically connecting the display area 9000 and the body 10 in the flexible tube 8300 as in the prior art. This can reduce the manufacturing cost.

[0163] Referring to Figure 1 , Figure 2 and Figure 19 , in some embodiments, the body 10 includes the housing 4000 and the handle assembly 6000. The handle assembly 6000 protrudes from one end of the housing 4000 away from the surface to be cleaned in the second direction. The display area 9000 is arranged on the handle assembly 6000. That is, in the use state, the handle assembly 6000 protrudes from the top end of the housing 4000. Arranging the display area 9000 on the handle assembly 6000 with the greatest height in the body 10 can make the display area 9000 be in a high position and not be easily blocked by other structures in the body 10. After the user lowers his head, he can easily observe the display area 9000 at any angle, so that he can learn the current operating status of the device in time.

[0164] Referring to Figure 1 , Figure 2 and Figure 19 , in some embodiments, the end surface of the handle assembly 6000 away from the surface to be cleaned in the second direction is the handle top surface 6210. The handle top surface 6210 is in the shape of an outwardly convex arc surface. The display area 9000 is located at the central position of the handle top surface 6210.

[0165] Specifically, the handle top surface 6210 protrudes upward and is in the shape of an arc surface. The central position thereof is the position with the greatest height thereon. Arranging the display area 9000 at this position can make the display area 9000 be in a high position. In other embodiments, the handle top surface 6210 can also be arranged in other shapes. As long as the display area 9000 is arranged at the position with the greatest height thereon.

[0166] Referring to Figure 3 and Figure 19In some embodiments, the handle assembly 6000 comprises a handle body 6100 and a handle cover 6200, the handle body 6100 is connected to the casing 4000, the handle cover 6200 is connected to an end of the handle body 6100 away from the casing 4000 in the second direction, and the handle cover 6200 is provided with a display gap 6220, and the display area 9000 is located at the display gap 6220.

[0167] Further, the handle assembly 6000 comprises a display 6300, which is installed between the handle body 6100 and the handle cover 6200 and exposed through the display gap 6220. Specifically, the handle body 6100 is fixedly connected to the top end of the casing top cover 4200, and the handle cover 6200 is connected to the top end of the handle body 6100. A hollow cavity is formed between the handle cover 6200 and the handle body 6100 for installing the display 6300. The top end of the display 6300 is exposed through the display gap 6220 to form the display area 9000.

[0168] In some embodiments, the display 6300 is fixedly installed on a display bracket 6400, which is fixedly installed on the handle body 6100, and the top end of the display 6300 is further provided with a display window 6500 in a transparent shape, which is used to protect the display 6300 and expose the content displayed by the display 6300.

[0169] Referring to Figure 3 and Figure 19 In some embodiments, the display area 9000 is used to display the dust concentration. In some embodiments, the display area 9000 has a dust concentration display bar, which is divided into a first display section and a second display section in different colors, and as the dust concentration increases, the first display section increases and the second display section decreases.

[0170] For example, the first display section is red and the second display section is blue. As the dust concentration increases, the red part of the dust concentration display bar increases and the blue part decreases; conversely, as the dust concentration decreases, the blue part of the dust concentration display bar increases and the red part decreases. In this way, the user can more intuitively and quickly understand the dirtiness of the surface to be cleaned.

[0171] Referring to Figure 3 , Figure 20 and Figure 23 In some embodiments, the body 10 has a suction port assembly 7000, and the flexible tube 8300 is connected to the suction port assembly 7000, and the suction port assembly 7000 comprises a dust concentration detection member 7100 for detecting the dust concentration of the fluid flowing through the flexible tube 8300.

[0172] Specifically, the suction assembly 7000 is installed at the first suction port 4340, and the airflow and garbage in the flexible pipe 8300 reach the first suction port 4340 through the suction assembly 7000. The dust concentration detection member 7100 detects the dust concentration of the fluid flowing through the flexible pipe 8300 and displays it on the display area 9000, so that the user can know the dirt level of the surface to be cleaned.

[0173] Referring to Figure 3 , Figure 20 and Figure 23 In some embodiments, the machine body 10 includes a circuit board 5300, and a negative pressure motor 3000 for providing suction force for the brush assembly 8200. The negative pressure motor 3000 and the dust concentration detection member 7100 are electrically connected to the circuit board 5300, and the circuit board 5300 can adjust the suction power of the negative pressure motor 3000 based on the measured dust concentration. Specifically, the dust concentration detection member 7100 detects the dust concentration of the fluid flowing through the flexible pipe 8300 and feeds it back to the circuit board 5300. The circuit board 5300 controls the display area 9000 to display the current dust concentration, and at the same time, adjusts the suction power of the negative pressure motor 3000 based on the current dust concentration, so that it can match the dust concentration. For example, when the dust concentration is too high, the suction power of the negative pressure motor 3000 is increased to increase the suction degree, and vice versa, the suction power of the negative pressure motor 3000 is reduced to save energy.

[0174] Referring to Figure 3 In some embodiments, when the dust concentration is greater than a first dust concentration threshold, the circuit board 5300 controls the negative pressure motor 3000 to increase the suction power; and when the dust concentration is less than a second dust concentration threshold, the circuit board 5300 controls the negative pressure motor 3000 to reduce the suction power. Specifically, the first dust concentration threshold can be a set upper limit value, and the second dust concentration threshold can be a set lower limit value. The first dust concentration threshold and the second dust concentration threshold can be set by the user or uniformly configured before leaving the factory. When the dust concentration is between the first dust concentration threshold and the second dust concentration threshold, it is defaulted that the current suction power of the negative pressure motor 3000 can meet the cleaning and energy saving requirements; when the dust concentration is greater than the first dust concentration threshold, it is defaulted that the current suction power of the negative pressure motor 3000 is insufficient, which may lead to incomplete cleaning, so the suction power needs to be increased; when the dust concentration is less than the second dust concentration threshold, it is defaulted that the current suction power of the negative pressure motor 3000 is excessive, which is not conducive to energy saving, so the suction power can be reduced.

[0175] Referring to Figure 3In some embodiments, the circuit board 5300 controls the negative pressure motor 3000 to increase / decrease the suction power by a preset ratio. Specifically, the ratio can be set by the user or uniformly configured before leaving the factory. For example, the suction power is increased / decreased by 20% of the current value. If the dust concentration is still not up to the standard after a single increase / decrease, the suction power is continuously increased / decreased in the above manner. In this way, fine adjustment of the suction power can be achieved.

[0176] Referring to Figure 21 , Figure 22 , Figure 23 and Figure 25 In some embodiments, the flexible pipe 8300 has a docking head 8310 at the end away from the holding assembly 8100, the mouthpiece assembly 7000 includes a sleeve 7200, the docking head 8310 and the sleeve 7200 are inserted and fitted, the dust concentration detection member 7100 includes an infrared emitting part 7110 and an infrared receiving part 7120 mounted on the sleeve 7200, and the infrared emitting part 7110 and the infrared receiving part 7120 are respectively arranged at the two ends of the sleeve 7200 in the radial direction. Specifically, the mouthpiece assembly 7000 includes a mouthpiece shell 7300, and the sleeve 7200 is fixed to the mouthpiece shell 7300. The infrared emitting part 7110 and the infrared receiving part 7120 are both infrared pairs, and are respectively fixed to the sleeve 7200 along the two ends of the sleeve 7200 in the radial direction. The infrared rays emitted by the infrared emitting part 7110 pass through the inside of the docking head 8310 and are received by the infrared receiving part 7120. According to the different dust concentrations in the docking head 8310, the information received by the infrared receiving part 7120 is also different, so that the current dust concentration value can be obtained accordingly.

[0177] Referring to Figure 21 , Figure 22 , Figure 23 and Figure 25 In some embodiments, the docking head 8310 is inserted into the sleeve 7200, the infrared emitting part 7110 and the infrared receiving part 7120 are both mounted on the outside of the sleeve 7200, and the sleeve 7200 is transparent. Specifically, the docking head 8310 extends from the opening of the mouthpiece shell 7300 and is inserted into the sleeve 7200. The sleeve 7200 is transparent and can be penetrated by infrared rays, so that even if the infrared emitting part 7110 and the infrared receiving part 7120 are mounted on the outside of the sleeve 7200, it does not affect the emission and reception of infrared rays. In other embodiments, the sleeve 7200 can also be inserted into the docking head 8310, so that the transparency of the sleeve 7200 is not required.

[0178] Referring to Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 25In some embodiments, the inner wall of the sleeve 7200 is provided with two abutting protrusions 7210 at two ends of the sleeve 7200 in the radial direction, and the end of the abutting head 8310 is provided with two abutting notches 8312 at two ends of the abutting head 8310 in the radial direction. Each abutting protrusion 7210 is inserted into the corresponding abutting notch 8312, and the positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two abutting protrusions 7210 respectively.

[0179] Specifically, each abutting protrusion 7210 is inserted into the corresponding abutting notch 8312 to limit the insertion of the abutting head 8310 into the sleeve 7200. The positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two abutting protrusions 7210 respectively, that is, the outer side of the region of the sleeve 7200 where one of the abutting protrusions 7210 is located is provided with the infrared emitting part 7110, and the outer side of the region of the sleeve 7200 where the other abutting protrusion 7210 is located is provided with the infrared receiving part 7120. Since the positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two abutting protrusions 7210 respectively, and each abutting protrusion 7210 is inserted into the corresponding abutting notch 8312, the infrared rays emitted by the infrared emitting part 7110 can just pass through the corresponding abutting protrusion 7210 and enter the abutting head 8310 through the corresponding abutting notch 8312. After passing through the abutting head 8310, the infrared rays will pass through the corresponding abutting protrusion 7210 from the other abutting notch 8312 and be received by the infrared receiving part 7120. In this way, the emission and reception of infrared rays can be achieved through the cooperation of the two abutting protrusions 7210 and the abutting notches 8312.

[0180] Referring to Figures 21-25 In some embodiments, a suction seal 7400 is further provided between the abutting head 8310 and the sleeve 7200 to enhance the sealing performance at this position. Specifically, the seal 7400 includes an annular seal ring 7410 and two lugs 7420 connected to the seal ring 7410, the two lugs 7420 are located at two ends of the seal ring 7410 in the radial direction, and each lug 7420 is provided with a seal clamping groove 7421. When the abutting head 8310 is inserted into the sleeve 7200 and the abutting protrusions 7210 are inserted into the abutting notches 8312, the inner wall of the abutting head 8310 protrudes inward compared to the inner wall of the abutting protrusions 7210. The seal 7400 can just fill the radial size difference between the inner wall of the abutting head 8310 and the inner wall of the abutting protrusions 7210, so that the airflow passing through this position is smoother. The inner side of the abutting protrusions 7210 is provided with a seal clamping block 7211, and the seal clamping block 7211 is inserted into the corresponding seal clamping groove 7421 to fix the position of the seal 7400.

[0181] Referring to Figure 20 and Figure 25In some embodiments, the flexible tube 8300 has a docking head 8310 at one end away from the holding assembly 8100, and the docking head 8310 and the mouthpiece assembly 7000 are provided with one of a flexible tube locking cavity 7310 and the other of a flexible tube lock 8313 elastically clamped into the flexible tube locking cavity 7310, and a flexible tube button 8314 connected to the flexible tube lock 8313, the flexible tube button 8314 being configured to be operable to press to drive the flexible tube lock 8313 out of the flexible tube locking cavity 7310.

[0182] In the embodiment shown in the drawings, the mouthpiece housing 7300 of the mouthpiece assembly 7000 is provided with the flexible tube locking cavity 7310, the docking head 8310 is provided with the flexible tube lock 8313 elastically clamped into the flexible tube locking cavity 7310, and the flexible tube button 8314 connected to the flexible tube lock 8313. Specifically, the flexible tube button 8314 and the flexible tube lock 8313 are integrally formed or fixedly connected, and the flexible tube button 8314 is connected to the housing of the docking head 8310 or the like through a resilient member, the resilient member pushes the flexible tube button 8314 through its resilience, and in turn pushes the flexible tube lock 8313 to be elastically clamped into the flexible tube locking cavity 7310. When the flexible tube button 8314 is pressed against the resilience, the flexible tube lock 8313 is driven out of the flexible tube locking cavity 7310. In this way, the locking and unlocking of the flexible tube 8300 and the body 10 can be achieved.

[0183] Referring to Figure 1 In some embodiments, the floor brush assembly 8200 includes a floor brush and a floor brush motor connected to the floor brush and configured to drive the floor brush to rotate, and the display area 9000 is configured to display the current of the floor brush motor.

[0184] In other embodiments, the floor brush motor can not be provided, and a vane connected to the floor brush can be provided, the vane being driven to rotate by the fluid in the air duct, and in turn driving the floor brush to rotate.

[0185] Referring to Figure 1 and Figure 3 In some embodiments, the body 10 includes a circuit board 5300, and a negative pressure motor 3000 configured to provide suction force to the floor brush, the negative pressure motor 3000 and the floor brush motor are both electrically connected to the circuit board 5300, and the circuit board 5300 is capable of adjusting the suction power of the negative pressure motor 3000 based on the current of the floor brush motor.

[0186] It can be understood that when the type of the surface to be cleaned is different, or the roughness of the surface to be cleaned is different, the resistance of the brush assembly 8200 during suction is different, and the current of the brush motor is also different. For example, when the surface to be cleaned is a material such as a carpet or a sofa, the resistance of the brush assembly 8200 during suction will be greater, and correspondingly, the current of the brush motor will also be greater. When the surface to be cleaned is a floor, the resistance of the brush assembly 8200 during suction will be smaller, and correspondingly, the current of the brush motor will also be smaller. For another example, for the same type of surface to be cleaned, the greater the roughness, the greater the resistance of the brush assembly 8200 during suction, and the greater the current of the brush motor. It can be understood that when the current of the brush motor fed back to the circuit board 5300 is too large, it indicates that the current suction resistance is too large, and the user uses more effort, at which time the suction power of the negative pressure motor 3000 needs to be appropriately reduced to reduce the suction resistance. When the current of the brush motor fed back to the circuit board 5300 is too small, it indicates that the current suction resistance is too small, and the brush assembly 8200 can slip on the surface to be cleaned, at which time the suction power of the negative pressure motor 3000 needs to be appropriately increased to increase the suction resistance.

[0187] Referring to Figure 1 and Figure 3 In some embodiments, when the current of the brush motor is greater than a first current threshold, the circuit board 5300 controls the negative pressure motor 3000 to reduce the suction power until the current of the brush motor is not greater than the first current threshold; when the current of the brush motor is less than a second current threshold, the circuit board 5300 controls the negative pressure motor 3000 to increase the suction power until the current of the brush motor is not less than the second current threshold. Specifically, the first current threshold can be a set upper limit value, and the second current threshold can be a set lower limit value. The first current threshold and the second current threshold can be set by the user or can be uniformly configured before leaving the factory. When the current of the brush motor is between the first current threshold and the second current threshold, it is defaulted that the suction resistance caused by the current suction power of the negative pressure motor 3000 is appropriate, the user is more labor-saving during cleaning, and the brush assembly 8200 is not easy to slip; when the current of the brush motor is greater than the first current threshold, it is defaulted that the current suction power of the negative pressure motor 3000 is too large, and the suction power needs to be reduced; when the current of the brush motor is less than the second current threshold, it is defaulted that the current suction power of the negative pressure motor 3000 is too small, and the suction power needs to be increased.

[0188] Referring to Figure 1 and Figure 3In some embodiments, the circuit board 5300 controls the negative pressure motor 3000 to increase / decrease the suction power by a preset ratio. Specifically, the ratio can be set by the user or uniformly configured before leaving the factory. For example, the suction power is increased / decreased by 20% of the current value. If the current of the brush motor still exceeds the first current threshold / second current threshold after a single increase / decrease, the suction power continues to be decreased / increased in the above manner. In this way, fine adjustment of the suction power can be achieved.

[0189] Referring to Figure 1 and Figure 3 In some embodiments, the brush assembly 8200 includes a brush, and the display area 9000 has a brush clogging identifier for identifying that the brush is in a clogging state. In this way, the user can be reminded to clean in time when the brush is clogged by hair and the like. In some embodiments, the body 10 includes a filter structure 100, and the display area 9000 has a filter structure clogging identifier for identifying that the filter structure 100 is in a clogging state. In this way, the user can be reminded to clean in time when the filter structure 100 is clogged.

[0190] Referring to Figures 30-39 As shown in the drawings, an embodiment of the dust cup structure 1000 applied to a dust collector provided by the present application includes a cup body 1100 and a dust throwing unit 1300. The cup body 1100 is configured with a first dust inlet 1111 and a dust storage cavity 1112. The cup body 1100 is provided with a cyclone separation unit 1200. The cyclone separation unit 1200 is provided with a cyclone passage 1211 in communication with the first dust inlet 1111, so that the solid mixture enters the cyclone separation passage through the first dust inlet 1111. One of the dust throwing unit 1300 and the cyclone separation unit 1200 is provided with a first clamping rib 1221, and the other is provided with a first clamping groove 1314 for clamping the first clamping rib 1221. The dust throwing unit 1300 is configured with a dust throwing port 1321 in communication with the cyclone passage 1211 and the dust storage cavity 1112. The solid mixture in the cyclone passage 1211 enters the dust storage cavity 1112 under the action of centrifugal force through the dust throwing port 1321. The dust collector can be the horizontal cleaning device described above, or the wireless dust collector described below, or a wired dust collector.

[0191] Specifically, the dewatering unit 1300 and the cyclone separation unit 1200 are each formed as an independent part, the dewatering unit 1300 is detachably fixed on the cyclone separation unit 1200 through the clamping cooperation of the first clamping rib 1221 and the first clamping groove 1314, the dewatering port 1321 protrudes from the outer surface of the cyclone outer wall 1220, so that the fixed mixture in the cyclone passage 1211 can enter the storage cavity 1112 through the dewatering port 1321, so that the garbage can be temporarily stored in the storage cavity 1112 stably, the connection and fixation of the dewatering unit 1300 are more simple and reliable, and the process complexity is reduced. Unlike the clamping mode of the dewatering unit 1300 and the cyclone separation unit 1200 through the first clamping rib 1221 and the first clamping groove 1314, in other embodiments, the dewatering unit 1300 and the cyclone separation unit 1200 can also be clamped and cooperated through the second connecting part 1222 and the second clamping rib 1316, and the detachable connection of the dewatering unit 1300 and the cyclone separation unit 1200 is realized through this mode. Among them, the cyclone separation unit 1200 is provided with the second connecting part 1222, and the dewatering unit 1300 is provided with the second clamping rib 1316 for clamping with the second connecting part 1222. Of course, the dewatering unit 1300 can also be provided with the second connecting part 1222, and the cyclone separation unit 1200 is provided with the second clamping rib 1316 for clamping cooperation with the second connecting part 1222, and the structure of the second connecting part 1222 and the second clamping rib 1316 will be described in detail below.

[0192] Referring to Figures 30-39 As shown in one of the embodiments, the cyclone separation unit 1200 includes a cyclone outer wall 1220 and a cyclone inner wall 1210 arranged in the cyclone outer wall 1220, and the cyclone outer wall 1220 cooperates with the cyclone inner wall 1210 to enclose a cyclone passage 1211; a cyclone cone 1230 is butted to the cyclone inner wall 1210, the cyclone cone 1230 is internally structured with a first fluid passage 1231 in communication with the air inlet of the negative pressure motor of the dust collector, the cyclone cone 1230 is provided with a plurality of first grids 1232 along the circumferential direction thereof, the first grids 1232 can block the solid mixture from entering the first fluid passage 1231; the through grooves 1233 between the adjacent two first grids 1232 are used to communicate the cyclone passage 1211 and the first fluid passage 1231. Understandably, the first grid 1232 is composed of a plurality of through grooves 1233. Specifically, in order to ensure that the cyclone passage 1211 has a higher negative pressure, i.e. the fluid loss of the whole system is small, the length of the through groove 1233 along the fluid flow direction is 28 mm, the groove width of the lower part of the through groove 1233 is 3 mm, and the groove width of the upper part of the through groove 1233 is 1.5 mm.

[0193] Under the action of the negative pressure motor, the large-particle garbage has a large centrifugal force, and will do a circular motion along the outer wall 1220 of the cyclone, and fly out of the cyclone passage 1211 when moving to the dust throwing port 1321. The small-particle garbage is blocked by the first grid 1232 when moving to the cyclone cone 1230 and rebounds, and then does a circular motion to be thrown out of the dust throwing port 1321 to the dust storage cavity 1112.

[0194] Referring to Figures 30-34 In one embodiment, the cyclone passage 1211 is arranged along the circumference of the cyclone cone 1230, and the horizontal height of the first grid 1232 is higher than the horizontal height of the first dust inlet 1111. The first dust inlet 1111 can be arranged below the first grid 1232, and a spiral ascending passage is arranged so that the mixed fluid is attracted upward by the suction force of the negative pressure motor through the spiral ascending passage.

[0195] Referring to Figures 30-39 In one embodiment, the outer wall 1220 of the cyclone is arc-shaped, and the center of curvature of the outer wall 1220 of the cyclone coincides with the center of curvature of the cyclone cone 1230. For example, in this embodiment, the outer wall 1220 of the cyclone is a circular shape with a constant diameter concentric with the cyclone cone 1230, which ensures that the fluid does a high-speed circular motion in the cyclone passage 1211, thereby generating a large centrifugal force, which is conducive to separating the dust and other solid mixtures from the fluid; at the same time, the circular shape of the outer wall 1220 of the cyclone also facilitates injection molding. The diameter of the inner wall 1210 of the cyclone can be adjusted according to the running speed of the fluid in the height direction. In other embodiments, the outer wall 1220 of the cyclone can be a variable-diameter cylinder, which can be an oval or a conical shape, etc.

[0196] Referring to Figures 30-32 In one embodiment, the diameter of the cyclone cone 1230 is d, the distance between the outer surface of the cyclone cone 1230 and the outer wall 1220 of the cyclone is L1, the minimum distance between the outer wall 1220 of the cyclone and the end of the dust throwing unit 1300 (i.e. the outermost side of the dust throwing port 1321) is L2, and the maximum distance between the outer wall 1220 of the cyclone and the end of the dust throwing unit 1300 is L3, wherein d is greater than L3, L3 is greater than L1, and L1 is greater than L2. For example, in this embodiment, d is 18 mm, L1 is 15 mm, L2 is 13 mm, and L3 is 16 mm.

[0197] Referring to Figures 32-39 In one embodiment, the horizontal height of the dust throwing port 1321 is higher than the horizontal height of the first grid 1232, so that the particles doing a circular motion lose the centripetal force when the speed is the fastest, and then fly out of the dust throwing port 1321 to the dust storage cavity 1112.

[0198] Referring to Figures 32-39As shown, in one of the embodiments, the dust throwing unit 1300 comprises a main body 1310 and a dust blocking part 1320 arranged on the main body 1310, the main body 1310 is used to connect with the cyclone outer wall 1220, and the dust blocking part 1320 extends in the direction towards the dust storage cavity 1112 relative to the main body 1310. When the cyclone passage 1211 is under negative pressure and has a high-speed rotating airflow running, it will attract the gas in the dust storage cavity 1112 to flow back to the cyclone passage 1211, thereby affecting the separation efficiency. By arranging the dust blocking part 1320 to extend in the direction towards the dust storage cavity 1112 relative to the main body 1310, the dust blocking part 1320 has a certain length to prevent the dust in the dust storage cavity 1112 from flowing back.

[0199] Referring to Figures 32-39 As shown, in one of the embodiments, the cyclone outer wall 1220 is provided with a first clamping rib 1221; the main body 1310 is provided with a first connecting part 1311, the first connecting part 1311 comprises a first branch 1312 and two second branches 1313 connected to the two sides of the first branch 1312 respectively, and the first branch 1312 and the two second branches 1313 cooperatively enclose a first clamping groove 1314; the first branch 1312 abuts against the top of the first clamping rib 1221. Through such arrangement, the clamping and fixing of the dust throwing unit 1300 and the cyclone outer wall 1220 are realized, and the connection of the two is more convenient.

[0200] Referring to Figures 32-39 As shown, in one of the embodiments, the cyclone outer wall 1220 extends a second connecting part 1222 in the direction towards the dust storage cavity 1112, the second connecting part 1222 comprises a third branch 1223 and a fourth branch 1224 connected perpendicularly, and the third branch 1223 and the fourth branch 1224 cooperatively enclose a second clamping groove 1225; the main body 1310 is provided with a first opening groove 1315 and a second clamping rib 1316 located in the first opening groove 1315, the groove wall of the first opening groove 1315 abuts against the third branch 1223, and the second clamping rib 1316 is clamped in the second clamping groove 1225.

[0201] Referring to Figures 32-39As shown in the drawings, in one of the embodiments, the second connecting part 1222 comprises a fifth branch 1226 connected to the bottom of the fourth branch 1224; the main body part 1310 extends a third connecting part 1317 in the direction towards the dust storage cavity 1112, and the third connecting part 1317 is provided with a second opening slot 1318 and a third clamping rib 1319 located at the bottom of the second opening slot 1318; the fourth branch 1224 is clamped in the second opening slot 1318, and the third clamping rib 1319 abuts against the bottom of the fifth branch 1226. Wherein, the dust throwing unit 1300 moves downward along the direction of gravity, so that the plurality of clamping ribs and the corresponding clamping slots are clamped and matched, thereby firmly fixing the dust throwing unit 1300 on the cyclone outer wall 1220, preventing the dust throwing unit 1300 from being tilted outward relative to the cyclone outer wall 1220.

[0202] As shown in the drawings, Figure 2 , Figure 12 , Figure 26 , Figure 27 As shown in the drawings, in one of the embodiments, the dust cup structure 1000 further comprises a dust cup upper cover 1400 rotationally connected with the cup body 1100, and the dust cup upper cover 1400 abuts against the dust throwing unit 1300. Specifically, the dust cup upper cover 1400 is provided with an upper cover lock catch 1450 for clamping with the cup body 1100, and by jiggling the upper cover lock catch 1450, the dust cup upper cover 1400 can be opened, so that the dust in the dust storage cavity 1112 can be poured out, realizing deep cleaning of the cup body 1100. Further, the dust cup upper cover 1400 is provided with an upper cover notch 1440, and the upper cover lock catch 1450 is located in the upper cover notch 1440, so that the user can conveniently manipulate the upper cover lock catch 1450 through the upper cover notch 1440, thereby conveniently taking the dust cup structure 1000; meanwhile, the dust cup structure 1000 can also be docked with the machine body 10 through the upper cover notch 1440.

[0203] As shown in the drawings, Figure 2 , Figure 12 , Figure 26 , Figure 27 As shown in the drawings, in one of the embodiments, the dust cup upper cover 1400 is elastically connected with an upper cover protrusion 1410, that is, the dust cup upper cover 1400 and the cup body 1100 are provided with an upper cover elastic member, and the upper cover protrusion 1410 is kept in a protruding state by the action of the upper cover elastic member; the machine body of the dust collector is provided with an upper cover clamping slot 4313 for clamping with the upper cover protrusion 1410, and the clamping and fixing of the upper cover protrusion 1410 and the upper cover clamping slot 4313 fixes the up-down position of the dust cup structure 1000 relative to the machine body.

[0204] As shown in the drawings, Figure 2 , Figure 12 , Figure 26 , Figure 27As shown, further, the upper cover of dust cup 1400 is rotationally connected with an upper cover rotating buckle 1420, which can abut against the upper cover protrusion 1410 to drive the upper cover protrusion 1410 to exit the upper cover clamping groove in a direction away from the upper cover clamping groove. For example, the user holds the upper cover rotating buckle 1420 and rotates it clockwise, which in turn pushes the upper cover protrusion 1410 to move in a direction away from the upper cover clamping groove until the upper cover protrusion 1410 is disengaged from the upper cover clamping groove; then the user forces upwardly to lift the dust cup structure 1000 by the dust cup handle 1430, so that the dust cup structure 1000 as a whole is separated from the machine body. When installing, after the dust cup structure 1000 is placed in the machine body, the hand is disengaged from the dust cup structure 1000, and the upper cover protrusion 1410 can be clamped in the upper cover clamping groove under the action of the upper cover elastic member.

[0205] Referring to Figures 33-39 As shown, in one of the embodiments, the cup body 1100 is provided with a first air outlet channel 1113 in communication with the first fluid channel 1231, the first air outlet channel 1113 has a first air outlet, and the first air outlet is provided with a first hepa filter 1114; the first air outlet channel 1113 is trumpet-shaped; at least part of the cyclone separation unit is located above the first air outlet channel 1113, that is, the projections of the two on the horizontal plane at least partially overlap. After the airflow passes through the first grid 1232 of the cyclone cone 1230, it moves downward along the first fluid channel 1231, enters the first air outlet channel 1113, and is filtered by the first hepa filter 1114 at the tail of the first air outlet channel 1113, so that small particles passing through the first grid 1232 can be blocked and filtered by the first hepa filter 1114, preventing small particles from entering the negative pressure motor and causing damage to components such as impellers, rotors, and circuit boards. The first hepa filter 1114 is composed of a material with certain air permeability, and generally the larger the hepa filter area, the smaller the loss caused to the entire fluid system. In order to ensure that the first hepa filter 1114 will cause a certain obstruction to the fluid, in this embodiment, the ventilation area of the first grid 1232 (the sum of the areas of each through slot 1233) is 1163.8 mm2. The hepa filter area is 7349.43 mm2. And in order to control the size of the entire machine to be the smallest, the negative pressure motor can be arranged at the rear of the dust cup structure 1000, so that the airflow directly enters the negative pressure motor. At the same time, because the upstream area of this section of airflow is small and the downstream area is large, in order to ensure the smoothness of the airflow, the first air outlet channel 1113 is provided in a trumpet shape with the opening facing the first hepa filter 1114.

[0206] In order to reduce the volume of the dust cup structure 1000, the projection of the cyclone passage 1211 and the first air outlet passage 1113 on the horizontal plane partially overlaps, and the cyclone passage 1211 is embedded in the first air outlet passage 1113. Since the cyclone passage 1211 is circular, the inner wall of the circular air duct is smooth, which can reduce the turbulence and vortex in the airflow, making the airflow more stable. Compared with air ducts of other shapes, the circular air duct has lower frictional resistance, which can reduce energy loss. In addition, the circular air duct can uniformly distribute the airflow in the cross section, reduce the unevenness of local airflow velocity, help maintain stable airflow, and make it smoothly enter the first air outlet passage 1113. In order to enable the fluid to obtain greater centrifugal force in the cyclone passage 1211, it is necessary to make the spiral upward passage as long as possible. For example, in the embodiment, the spiral angle is 360 degrees, that is, one turn. In other embodiments, the spiral passage can be 720 degrees or more, so that the cyclone passage 1211 can spiral several turns. At the same time, since the cyclone passage 1211 is spirally upward, the lower part of the cyclone passage 1211 will have a vacancy, which is just used as a part of the first air outlet passage 1113, so that the fluid can be better diverted, and space is saved.

[0207] Referring to Figure 30 As shown in the drawings, in one embodiment, the body of the dust collector is provided with a leak-proof elastic member and a leak-proof member 1122 connected to the leak-proof elastic member. The leak-proof elastic member is used to drive the leak-proof member 1122 to extend relative to the cup body 1100. In the extended state, the dust cup structure 1000 interferes with the body to block the installation of the cup body 1100, and the dust cup structure 1000 cannot be installed in the body. The first hypap 1114 is provided with a leak-proof blocking piece 1115, which is used to abut against the leak-proof member 1122. That is, when the first hypap 1114 is installed in the body, the leak-proof blocking piece 1115 will press the leak-proof member 1122, so that the leak-proof member 1122 is retracted relative to the cup body 1100. The dust cup structure 1000 and the body no longer interfere, so that the normal assembly of the dust cup structure 1000 can be realized.

[0208] In one embodiment, the dust cup structure 1000 further comprises a bottom cover lock 1510 and a dust cup bottom cover 1500 rotatably connected to the cup body 1100. One end of the bottom cover lock 1510 is clamped to the cup body 1100, and the other end is clamped to the dust cup bottom cover 1500, so as to lock the dust cup bottom cover 1500 and the cup body 1100. The bottom cover lock 1510 is configured to be operable to separate from the dust cup bottom cover 1500 to release the connection between the dust cup bottom cover 1500 and the cup body 1100.

[0209] Specifically, one of the dust cup bottom cover 1500 and the cleaner body is provided with a bottom cover positioning protrusion 4311, and the other is provided with a bottom cover positioning groove 1520 for clamping the bottom cover positioning protrusion 4311. For example, in the embodiment, the bottom cover positioning groove 1520 is arranged on the dust cup bottom cover 1500, and the bottom cover positioning protrusion 4311 is arranged in the cleaner body, and the dust cup structure 1000 is positioned by clamping the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520. In other embodiments, the dust cup bottom cover 1500 is also provided with a bottom cover positioning protrusion, and the cleaner body is provided with a bottom cover positioning groove 1520.

For example, in the embodiment, the cup-machine hook 1131 is arranged on the cup body 1100, and the cup-machine positioning groove is arranged on the body. The cup-machine hook 1131 can be arranged at the upper end of the dust cup structure 1000, and the bottom cover positioning groove 1520 of the foregoing embodiment can be arranged at the bottom of the dust cup structure 1000, so that the connection between the dust cup structure 1000 and the body is more stable and reliable by arranging the fixing structure at the upper end and the bottom. It can be understood that in other embodiments, the cup body 1100 can be provided with a cup-machine positioning groove, and the body can be provided with a cup-machine hook 1131.

[0211] Referring to Figures 1-3 and Figure 19 , in some embodiments, the body 10 comprises a machine shell 4000 and a handle assembly 6000, the dust cup structure 1000 and other components such as the negative pressure motor are installed in the machine shell 4000, and the handle assembly 6000 protrudes from the end of the machine shell 4000 away from the surface to be cleaned, i.e. in the use state, the handle assembly 6000 protrudes from the top end of the machine shell 4000. In this way, the handle assembly 6000 constitutes the first part of the outer surface of the cleaner, the dust cup upper cover 1400 of the dust cup structure 1000 is a quarter of a circle, so that it can constitute the second part of the outer surface of the cleaner when installed in the machine shell 4000, and the machine shell 4000 constitutes the third part of the outer surface of the cleaner, so that the outer surface of the cleaner is relatively flat and beautiful, and more space-saving, and convenient for the user to operate. Further, the machine shell 4000 has a battery mounting port 4330 at the end away from the dust cup structure 1000 in the first direction, and the battery pack assembly 5100 is detachably installed in the machine shell 4000 through the battery mounting port 4330.

[0212] Specifically, the housing 4000 includes a fixedly connected housing base 4100 and a housing top cover 4200 fixed to an end of the housing base 4100 away from the surface to be cleaned in the second direction. A battery mounting port 4330 is formed between the housing base 4100 and the housing top cover 4200 at an end thereof away from the dust cup structure 1000 in the first direction. The battery pack assembly 5100 can be mounted and dismounted through the battery mounting port 4330 to facilitate maintenance, replacement and charging thereof.

[0213] Referring to Figures 1-3 and Figure 19 In an embodiment, the handle assembly 6000 includes a handle body 6100 connected to the housing 4000 and a handle cover 6200 connected to an end of the handle body 6100 away from the housing 4000, and a display gap 6220 is formed in the handle cover 6200, and a display area 9000 for displaying a target parameter such as dust concentration is located at the display gap 6220.

[0214] Referring to Figures 1-3 and Figure 19 Further, the handle assembly 6000 includes a display 6300 mounted between the handle body 6100 and the handle cover 6200 and exposed through the display gap 6220. Specifically, the handle body 6100 is fixedly connected to a top end of the housing top cover 4200, and the handle cover 6200 is connected to a top end of the handle body 6100. A hollow cavity is formed between the handle cover 6200 and the handle body 6100 for mounting the display 6300. The display 6300 is exposed through the display gap 6220 at a top end thereof to form the display area 9000.

[0215] Referring to Figure 40 , Figure 41 and Figure 47As shown, the wireless dust collector provided by an embodiment of the present application includes a machine body 10, which includes a machine shell 4000, and a battery pack assembly and a negative pressure motor assembly 200 are arranged in the machine shell 4000; the battery pack assembly 5100 is located on a side of the negative pressure motor assembly 200 away from a surface to be cleaned along a second direction; the negative pressure motor assembly 200 includes a negative pressure motor 3000 and a motor cover structure 2000 for mounting the negative pressure motor 3000, and the motor cover structure 2000 is provided with a first air outlet 2170. The motor cover structure 2000 is provided with at least two second air outlets 2310, and a third air outlet 2110 is arranged between the at least two second air outlets 2310, and the fluid flow directions in the third air outlet 2110 and the second air outlets 2310 are opposite; it can be understood that the second air outlets 2310 and the third air outlet 2110 are used for exhausting air for the negative pressure motor 3000; wherein the second air outlets 2310 and the third air outlet 2110 cooperate to exhaust the fluid introduced by the negative pressure motor 3000. In this way, the airflow flow direction can change multiple times, and the airflow flow path is longer, so that the exhaust airflow speed is low, the noise is reduced, and multiple air outlets also isolate the noise generated by the negative pressure motor 3000, greatly reducing the noise of the negative pressure motor 3000, and the wireless dust collector is designed in multiple sections, greatly improving the space utilization of the wireless dust collector.

[0216] As shown, Figures 40-41 In one embodiment, the motor cover structure 2000 includes a motor front cover 2100, a motor middle cover 2200, a motor rear cover 2300 and a rear cover cap 2400 arranged in sequence along the axial direction of the negative pressure motor 3000; referring to Figure 42 As shown, the motor middle cover 2200 is provided with a second air outlet 2210 for communicating with the air outlet of the negative pressure motor 3000; referring to Figure 42 and Figure 40 As shown, the motor rear cover 2300 is connected with the motor middle cover 2200, and the two cooperate to enclose the second air outlet 2310 communicating with the second air outlet 2210; referring to Figure 44 As shown, the motor front cover 2100 is connected with the side of the motor middle cover 2200 away from the motor rear cover 2300, and the motor front cover 2100 is provided with a third air outlet 2110 communicating with the second air outlet 2310. Further, referring to Figure 45As shown, the rear cover 2400 is butted against the side of the motor rear cover 2300 away from the motor middle cover 2200, the rear cover 2400 is provided with a fourth air outlet channel 2410, the fourth air outlet channel 2410 is communicated with the third air outlet channel 2110 and the first air outlet 2170, the fluid flow directions in the fourth air outlet channel 2410 and the third air outlet channel 2110 are opposite; wherein, the fluid flows through the second air outlet 2210, the second air outlet channel 2310, the third air outlet channel 2110 and the fourth air outlet channel 2410 in sequence, and is discharged through the first air outlet 2170. As shown in Figure 40 As shown, two second air outlet channels 2310 are provided, and as an example, the two second air outlet channels 2310 are respectively arranged on the left side and the right side of the negative pressure motor 3000 along the radial direction of the negative pressure motor 3000; the fluid in the two second air outlet channels 2310 respectively flows around the axial direction of the negative pressure motor 3000, and flows in the direction from top to bottom, until entering the third air outlet channel 2110; for example, in the perspective of Figure 44 As shown, the fluid in the third air outlet channel 2110 flows around the axial direction of the negative pressure motor 3000, and the flow direction is from bottom to top, until entering the fourth air outlet channel 2410; as shown in Figure 45 As shown, the fluid in the fourth air outlet channel 2410 flows around the axial direction of the negative pressure motor 3000, and the flow direction is from top to bottom.

[0217] The above motor cover structure 2000, the fluid flows through the second air outlet 2210, the second air outlet channel 2310, the third air outlet channel and the fourth air outlet channel 2410 in sequence, and is discharged through the first air outlet 2170, the second air outlet 2210 is arranged on the motor middle cover 2200, the second air outlet channel 2310 is arranged on the motor rear cover 2300, the third air outlet channel is arranged on the motor front cover 2100, and the fourth air outlet channel 2410 is arranged on the rear cover 2400. As an example, the motor front cover 2100, the motor middle cover 2200, the motor rear cover 2300 and the rear cover 2400 are arranged from left to right in sequence, the fluid flowing out of the motor middle cover 2200 first flows left into the motor rear cover 2300 and flows in the motor rear cover 2300, then the fluid flows left to the motor front cover 2100 and flows in the motor front cover 2100, and then flows right to the rear cover 2400 and flows in the rear cover 2400, and the flow directions of the air flow in the adjacent air outlet channels are opposite, that is to say, the air flow not only circulates multiple times along the circumferential direction of the motor cover structure 2000, but also circulates along the axial direction of the motor cover structure 2000, the flow direction of the air flow changes multiple times, and the flow path of the air flow is longer, so that the speed of the discharged air flow is low, the noise is reduced, multiple air outlet channels also isolate the noise generated by the negative pressure motor 3000, greatly reducing the noise of the negative pressure motor 3000, and the motor cover structure 2000 is designed in multiple sections, greatly improving the space utilization.

[0218] AsFigure 43 and Figure 44 As shown, in one embodiment, both the third air outlet channel 2110 and the fourth air outlet channel 2410 are arranged axially around the negative pressure motor 3000. By arranging the air outlet channels around the axial direction of the negative pressure motor 3000, the airflow path is extended, resulting in a lower exhaust air velocity and reduced noise. Furthermore, the multiple air outlet channels also isolate the noise generated by the negative pressure motor 3000, greatly reducing the noise level of the negative pressure motor 3000.

[0219] like Figure 42 As shown, in one embodiment, the motor housing 2200 includes an inner wall 2201 and an outer wall 2202 surrounding the inner wall 2201. A partition 2203 is provided between the inner wall 2201 and the outer wall 2202. The partition 2203 divides the cavity formed by the inner wall 2201 and the outer wall 2202 into at least two air outlet channels. The fluid flow directions of the two adjacent air outlet channels are different. By dividing the air outlet channels in the motor housing 2200 into multiple segments through the partition 2203, the space utilization rate is greatly improved.

[0220] See Figures 41-44 As shown, in one embodiment, the motor front cover 2100, motor middle cover 2200, and motor rear cover 2300 are respectively provided with a front cover mounting cavity 2120, a middle cover mounting cavity 2260, and a rear cover mounting cavity 2340, which together constitute the motor mounting cavity. A second air outlet 2210 is disposed on the cavity wall of the middle cover mounting cavity 2260. The second air outlet 2210 can be located within one-half to one-third of the axial length of the negative pressure motor 3000, ensuring that the airflow from the negative pressure motor 3000's air outlet can be quickly discharged, preventing the negative pressure motor 3000 from overheating.

[0221] See Figures 40-42 As shown, a second air outlet channel 2310 is formed between the outer wall of the motor rear cover 2300 and the cavity wall of the rear cover mounting cavity 2340. In one embodiment, there are two second air outlet channels 2310, which are arranged circumferentially at intervals along the negative pressure motor 3000, that is, the two second air outlet channels 2310 are distributed radially along the negative pressure motor 3000, and the two second air outlet channels 2310 are arranged in a Y-shape. The arrangement of multiple second air outlet channels 2310 can increase the airflow space, extend the airflow path, and reduce fluid resistance.

[0222] See Figures 40-42As shown, in one of the embodiments, the second air outlet 2210 includes two, each second air outlet 2210 corresponding to a second air outlet channel 2310; the center line of each second air outlet 2210 intersects the axis of the negative pressure motor 3000; the included angle of the center lines of the two second air outlets 2210 is 30-90 degrees, and further, the included angle of the center lines of the two second air outlets 2210 can be 67 degrees. The second air outlet 2210 is dispersedly arranged, which is helpful for heat dissipation in the air outlet channel and rational use of the internal space of the motor cover structure 2000, and ensures that the air outlet can be divided into two.

[0223] Referring to Figure 40 As shown, in one of the embodiments, the motor rear cover 2300 is provided with a first rear cover cavity 2311 and a second rear cover cavity 2312 which are in communication with each other, and the first rear cover cavity 2311 and the second rear cover cavity 2312 form the second air outlet channel 2310; referring to Figure 42 As shown, the motor middle cover 2200 is provided with a first middle cover cavity 2220 and a second middle cover cavity 2230 which are isolated from each other, the first middle cover cavity 2220 communicates the second air outlet 2210 and the first rear cover cavity 2311, and the second middle cover cavity 2230 communicates the second air outlet channel 2310 and the third air outlet channel. In this way, the airflow flow in the motor middle cover 2200, the motor rear cover 2300 and the rear cover cover 2400 is realized, and the air outlet channel with the guided airflow flow direction is formed, so that the airflow can not only flow circumferentially along the negative pressure motor 3000, but also move axially along the negative pressure motor 3000.

[0224] Referring to Figure 40 As shown, in one of the embodiments, a first blocking rib 2313 is arranged between the first middle cover cavity 2220 and the first rear cover cavity 2311, and the first blocking rib 2313 is used to guide the fluid flow of the first middle cover cavity 2220 to the first rear cover cavity 2311. The first blocking rib 2313 can prevent the airflow from the second air outlet 2210 from directly entering the second rear cover cavity 2312, and prevent the airflow from short circuiting to cause noise.

[0225] Referring to Figures 42-40 As shown, in one of the embodiments, the motor middle cover 2200 and the motor rear cover 2300 are respectively provided with a third middle cover cavity 2240 and a third rear cover cavity 2320, and the third middle cover cavity 2240 and the third rear cover cavity 2320 communicate the third air outlet channel and the fourth air outlet channel 2410. In this way, the communication between the rear cover cover 2400 and the motor front cover 2100 is realized, so that the airflow moves axially from the rear cover cover 2400 to the motor front cover 2100 along the negative pressure motor 3000, and can play a role in extending the air duct.

[0226] Referring to Figure 41As shown, in one embodiment, the first air outlet 2170 is located in the motor front cover 2100, and the first air outlet 2170 and the second air outlet 2210 are respectively located on the two sides of the negative pressure motor 3000 in the radial direction, so that the flow path of the airflow in the motor cover structure 2000 is lengthened, the fluid loss is reduced, and the noise is reduced. Among them, the motor front cover 2100 is provided with a first front cover cavity 2180 which is in communication with the first air outlet 2170; see Figures 41-40 As shown, the motor rear cover 2300 and the motor middle cover 2200 are respectively provided with a fourth rear cover cavity 2330 and a fourth middle cover cavity 2250, and the fourth rear cover cavity 2330 and the fourth middle cover cavity 2250 are in communication with the fourth air outlet channel 2410 and the first front cover cavity 2180, so as to converge the fluid of the two third air outlet channels 2110 and introduce the fluid into the fourth air outlet channel 2410, so that the airflow in the rear cover cover 2400 passes through the fourth rear cover cavity 2330, the fourth middle cover cavity 2250 and the first front cover cavity 2180 in sequence, and is discharged through the first air outlet 2170.

[0227] Referring to Figures 41-40As shown, in one of the embodiments, the third middle cover cavity 2240 and the third rear cover cavity 2320 are arranged along the axial direction of the negative pressure motor 3000, and the fluid flow directions in the third middle cover cavity 2240 and the fourth middle cover cavity 2250 are opposite. The third middle cover cavity 2240 and the third rear cover cavity 2320 have substantially consistent shapes, so that the fluid flow is smoother, and the fluid loss caused by the sudden expansion of the wall surface is reduced. Further, the first front cover cavity 2180, the fourth middle cover cavity 2250, and the fourth rear cover cavity 2330 are arranged along the axial direction of the negative pressure motor 3000, and the first front cover cavity 2180, the fourth middle cover cavity 2250, and the fourth rear cover cavity 2330 have substantially consistent shapes, thereby reducing the flow rate loss caused by the uneven wall surface through which the fluid flows; the third middle cover cavity 2240 and the fourth middle cover cavity 2250 are respectively located on the two sides of the radial direction of the negative pressure motor 3000, thereby prolonging the flow path of the airflow. Specifically, the fluid passes through the second air outlet 2210, enters the first middle cover cavity 2220 of the motor middle cover 2200 and the first rear cover cavity 2311 of the motor rear cover 2300, and then passes through the second air outlet channel 2310 extending along the circumferential direction of the negative pressure motor 3000, and enters the second middle cover cavity 2230 of the motor middle cover 2200 upward; then the two airflows flowing out of the two second air outlets 2210 mix in the third air outlet channel of the motor front cover 2100; then the mixed airflow flows downward, sequentially passes through the third middle cover cavity 2240 in the motor middle cover 2200 and the third rear cover cavity 2320 of the motor rear cover 2300, and then enters the fourth air outlet channel 2410 formed by the motor rear cover 2300 and the rear cover cover 2400; then the airflow flows upward along the fourth rear cover cavity 2330 of the motor rear cover 2300, the fourth middle cover cavity 2250 of the motor middle cover 2200, and the first front cover cavity 2180 of the motor front cover 2100, and then is discharged out of the motor cover structure 2000 through the first air outlet 2170. Specifically, the airflow can be filtered by the air outlet filter provided in the wireless dust collector and then discharged out of the dust collector body 10. The airflow not only circulates multiple times along the circumferential direction of the motor cover structure 2000, but also circulates along the axial direction of the motor cover structure 2000, the flow direction of the airflow changes multiple times, and the flow path of the airflow is longer, so that the discharged airflow has a low speed, the noise is reduced, multiple air outlet channels also isolate the noise generated by the negative pressure motor 3000, greatly reduce the noise of the negative pressure motor 3000, and the motor cover structure 2000 is designed in multiple sections, thereby greatly improving the space utilization.

[0228] Referring to Figure 40As shown, in one of the embodiments, the motor front cover 2100 is provided with a front cover sealing groove 2130 for installing a motor cover sealing ring 2140. The motor cover sealing ring 2140 is embedded in the front cover sealing groove 2130, and the motor cover sealing ring 2140 is in press-fit with the cavity wall of the installation cavity of the machine body 10, i.e. the installation cavity of the battery pack assembly and the motor cover structure 2000. The cavity wall of the installation cavity is located between the first air outlet of the dust cup structure and the motor cover structure, so that the airflow sucked by the wireless dust collector can enter the dust cup structure, and after being filtered and separated by the dust cup structure, it enters the air inlet of the negative pressure motor 3000 through the first air outlet of the dust cup structure, ensuring the sealing effect, and then flows to the second air outlet 2210 through the air outlet of the negative pressure motor 3000.

[0229] Referring to Figure 40 As shown, the motor front cover 2100 is provided with a front cover damping member 2150, which can be made of soft rubber material, to reduce the axial vibration of the negative pressure motor 3000 and thus reduce the noise. Further, the motor rear cover 2300 can also be provided with a rear cover damping member 2350 made of soft rubber material to reduce axial vibration and noise. The rear cover damping member 2350 can be bowl-shaped to wrap around the end of the negative pressure motor, so as to reduce not only the axial vibration but also the circumferential vibration. More specifically, the front cover damping member 2150 and the rear cover damping member 2350 do not completely overlap in the axial direction of the negative pressure motor 3000, so as to ensure the air outlet performance of the negative pressure motor 3000 and meet the heat dissipation requirements thereof.

[0230] Referring to Figure 40 As shown, in one of the embodiments, the motor rear cover 2300 and the rear cover cap 2400 are respectively provided with a rear cover wire passing hole 2371 and a cap wire passing hole 2431. The wires of the negative pressure motor 3000 pass through the rear cover wire passing hole 2371 and the cap wire passing hole 2431 and are connected to the circuit board. Further, the rear cover wire passing hole 2371 and the cap wire passing hole 2431 are respectively connected with a rear cover wire plug 2372 and a cap wire plug 2432 to realize the sealing of the air outlet channel.

[0231] Referring to Figure 41 and Figure 44 As shown, in one of the embodiments, one of the motor front cover 2100 and the motor middle cover 2200 is provided with a front cover buckle 2160, and the other is provided with a middle cover buckle slot 2271 for buckling with the front cover buckle 2160. Further, referring to Figure 42 and Figure 40 As shown, one of the motor middle cover 2200 and the motor rear cover 2300 is provided with a middle cover buckle 2272, and the other is provided with a rear cover buckle slot 2361 for buckling with the middle cover buckle 2272. Referring to Figure 40 andFigure 45 As shown, one of the motor rear cover 2300 and the rear cover cap 2400 is provided with a rear cover buckle 2362, and the other is provided with a cap buckle slot 2421 for buckling with the rear cover buckle 2362. Through the cooperation of the buckle and the buckle slot, the assembly of the motor cover structure 2000 is simpler, and the cooperation of the buckle and the buckle slot is more space-saving compared with the screw connection mode. Further, the joints between the adjacent two cover bodies (the motor front cover 2100, the motor middle cover 2200 and the motor rear cover 2300 are collectively referred to as cover bodies) are respectively provided with a notch and a rib position, and the cooperation of the notch and the rib position realizes the sealing between the adjacent two cover bodies through buckling.

[0232] Referring to Figure 47 As shown, in an embodiment, the machine body 10 is provided with a suction port assembly communicating with the air inlet of the negative pressure motor 3000. After the airflow enters the motor cover structure 2000, it not only circulates multiple times along the circumference of the motor cover structure 2000, but also circulates along the axial direction of the motor cover structure 2000. The airflow direction changes multiple times, and the airflow flow path is longer, so the exhaust airflow speed is low, the noise is reduced, multiple air outlets also isolate the noise generated by the negative pressure motor 3000, greatly reducing the noise of the negative pressure motor 3000, and the multi-section split design of the motor cover structure 2000 greatly improves the space utilization rate of the motor cover structure 2000.

[0233] Referring to Figure 47 As shown, in one embodiment, the central axis Z1 of the negative pressure motor 3000 and the central axis Z2 of the suction port assembly are spaced apart in the radial direction of the negative pressure motor 3000. Specifically, the central axis Z2 of the suction port assembly is also the center line of the machine body 10, and the central axis Z1 of the negative pressure motor 3000 is closer to the air outlet of the negative pressure motor 3000 relative to the central axis Z2 of the suction port assembly, for example, the radial gap between the central axis Z1 of the negative pressure motor 3000 and the central axis Z2 of the suction port assembly is 7mm, in this way, the second air outlet 2310 has a larger air passing area, which can reduce fluid loss and reduce noise. At the same time, the negative pressure motor 3000 and the first air outlet of the dust cup structure are approximately coaxial, making the air duct smoother, which is conducive to the airflow in the dust cup structure entering the negative pressure motor 3000. Among them, the negative pressure motor 3000 can be a brushless digital DC motor, which has the characteristics of small size, large air volume and high efficiency. In other embodiments, the negative pressure motor 3000 can also be a brush DC negative pressure motor 3000. In some other embodiments, when the negative pressure motor 3000 matches an alternating current power supply, the negative pressure motor 3000 can also be an alternating current motor.
