Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to horizontal cleaning equipment. Background Art

[0002] With the continuous development of science and technology, cleaning equipment such as vacuum cleaners and floor scrubbers have entered thousands of households, bringing great convenience to people's daily cleaning. Among them, horizontal cleaning equipment with a separate body and flexible tube, gripping assembly, and floor brush assembly is currently a more common type. When using such equipment, the user can move the gripping assembly to drive the body through the flexible tube connected between the gripping assembly and the body, so that the body moves synchronously through the rollers set at its bottom. In such equipment, a display area is usually provided specifically for displaying target parameters such as the remaining power. However, in the related art, the conventional display area setting method is to set the display area on the gripping assembly. This method is not only prone to visual blind spots and difficult to be observed in time, but also requires a wire to be set in the flexible tube between the gripping assembly and the body to achieve electrical connection between the display area and the body, and the manufacturing cost is relatively high. Utility Model Content

[0003] Based on this, it is necessary to provide a horizontal cleaning device in which the display area is set in a position where there is no visual blind spot, can be observed by the user in time, and is convenient for the user to understand the current operating status of the equipment in time, and the manufacturing cost is lower.

[0004] A horizontal cleaning device, comprising:

[0017] In some embodiments, the circuit board controls the negative pressure motor to increase / decrease suction power according to a preset ratio.

[0018] In some embodiments, the flexible tube has a docking joint at one end away from the holding assembly, the suction port assembly includes a sleeve, the docking joint and the sleeve are plugged into each other, and the dust concentration detection component includes an infrared emitting part and an infrared receiving part installed on the sleeve, and the infrared emitting part and the infrared receiving part are arranged at the radial ends of the sleeve.

[0034] In the above-mentioned horizontal cleaning device, the display area is provided on the body. When in use, the body is usually placed on the surface to be cleaned. The overall height is lower than that of the cleaning module, and the user can observe in time by simply lowering his head. On this basis, in the second direction, the distance between the display area and the surface to be cleaned is greater than the distance between other areas of the body and the surface to be cleaned, that is, the display area is at the position in the body where the distance between it and the surface to be cleaned is the largest, that is, the display area is at the position with the greatest height on the body. Such a setting makes it difficult for the display area to be blocked by other structures in the body, so that visual blind spots are not easy to exist. After the user lowers his head, the display area can be easily observed at any angle, so that the current operating status of the device can be understood in time. In addition, since the display area is provided on the body rather than the grip assembly, there is no need to provide a wire for electrically connecting the display area and the body in the flexible tube as in the prior art, which can reduce manufacturing costs.

[0095] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0096] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0097] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0098] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0099] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0100] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0101] See Figures 1 to 3 The machine body 10 provided in one embodiment of the present application is used for a horizontal cleaning device, which includes a gripping assembly 8100, a floor brush assembly 8200, and a flexible tube 8300. One end of the gripping assembly 8100 is connected to the floor brush assembly 8200, and the other end is connected to the flexible tube 8300. The end of the flexible tube 8300 facing away from the gripping assembly 8100 is connected to the machine body 10. The machine body 10 has a roller at one end thereof that is close to the surface to be cleaned along the second direction. In the working state, the gripping assembly 8100 is configured to be operably moved on the surface to be cleaned, so as to drive the machine body 10 to move on the surface to be cleaned via the roller via the flexible tube 8300.

[0102] The body 10 provided in one embodiment of the present application includes a housing 4000, and a filter structure 100, a negative pressure motor assembly 200, a power supply assembly (in one embodiment, the power supply assembly is a battery pack assembly 5100) and a handle assembly 6000 installed on the housing 4000. Among them, 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 near one end of the filter structure 100 along the first direction. The power supply assembly is located on the 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 the side of the power supply assembly away from the negative pressure motor assembly 200 along the second direction. Among them, 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.

[0103] Typically, the airflow direction within the negative pressure motor 3000 is roughly parallel to its axial direction. In the above embodiment, since the negative pressure motor assembly 200 is 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 airflow flowing out of the filter structure 100 will flow roughly along the first direction toward the negative pressure motor assembly 200, directly reaching the negative pressure motor air inlet 3100, and flowing from the negative pressure motor air inlet 3100 roughly along the first direction into the negative pressure motor 3000. It can be seen that after flowing out of the filter structure 100, the airflow can flow directly into the negative pressure motor 3000 without having to turn at a large angle, thereby reducing wind resistance, making the airflow flow smoother, and reducing fluid loss. In addition, the second direction is the height direction of the body 10, and the first direction is perpendicular to the second direction, that is, when in use, 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 one side of the filter structure 100 along the first direction, that is, all three are located on one side of the filter structure 100 in the horizontal direction. The power supply assembly is located on the side of the negative pressure motor assembly 200 that is away from the surface to be cleaned along the second direction, and the handle assembly 6000 is located on the side of the power supply assembly that is away from the negative pressure motor assembly 200 along the second direction. That is, in use, 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 in the first direction, that is, the negative pressure motor 3000 is "laid down". This arrangement can minimize the space occupied by the negative pressure motor assembly 200 in the second direction. 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. This can effectively utilize the space saved in the second direction by the negative pressure motor 3000 "lying down", making the structural layout within the body 10 more compact and the body 10 occupying less space. In addition, since the negative pressure motor assembly 200 is a relatively heavier structure in the body 10, setting it under the handle assembly 6000 can concentrate most of the weight of the body 10 under the handle assembly 6000, so when the user pulls the handle assembly 6000, it will be easier to pull.

[0104] Figures 1 to 3 In the visual angle, 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. When the horizontal cleaning device is in use, the second direction is the up-down direction.

[0105] See Figures 3 to 6 In some embodiments, the handle assembly 6000 and the power supply assembly overlap at least partially along the third direction, and the handle assembly 6000 is larger than the power supply assembly along the third direction. This configuration allows the user to save effort when lifting the handle assembly 6000 to move or store the horizontal cleaning device over long distances.

[0106] See Figures 3 to 6 In some embodiments, the power supply component is a battery pack component 5100, and the housing 4000 has a battery installation port 4330 at one end away from the filter structure 100 along the first direction, and the battery pack component 5100 can be removably installed in the housing 4000 through the battery installation port 4330.

[0107] Specifically, the housing 4000 includes a housing base 4100 and a housing top cover 4200, which are fixedly connected. The housing top cover 4200 is fixed to the end of the housing base 4100 that faces away from the surface to be cleaned along the second direction. A battery installation port 4330 is formed between the ends of the housing base 4100 and the housing top cover 4200 that face away from the filter structure 100 along the first direction. The battery pack assembly 5100 can be installed and removed through the battery installation port 4330, facilitating maintenance, replacement, and charging.

[0108] In some embodiments, a charging port is provided on the portion of the battery pack assembly 5100 exposed at the battery mounting port 4330. Since the charging port is exposed at the battery mounting port 4330, it is convenient for the user to charge the battery pack assembly 5100 through the charging port.

[0109] In other embodiments, the power supply component is a power cord, which is connected to an external power source for power supply. In the following embodiments, the power supply component shown in the drawings is mainly described as a battery pack component 5100.

[0110] See Figures 4 and 5 In some embodiments, the end of the battery pack assembly 5100 facing away from the filter structure 100 along the first direction does not extend beyond the end of the housing 4000 facing away from the filter structure 100 along the first direction. That is, the battery pack assembly 5100 is completely installed in the housing 4000 through the battery installation opening 4330, and its outer end does not protrude from the end surface of the housing 4000. This configuration protects the battery pack assembly 5100 from damage caused by collisions and reduces the risk of the battery pack assembly 5100 falling out due to external force.

[0111] See Figures 3 to 7 In some embodiments, a battery compartment 5200 is provided in the housing 4000 and connected thereto, and the battery pack assembly 5100 can be detachably installed in the battery compartment 5200 through the battery installation port 4330, and the battery pack assembly 5100 and the battery compartment 5200 are slidably fitted along a first direction.

[0112] Specifically, the battery compartment 5200 is fixedly mounted within the housing 4000. The end of the battery compartment 5200, facing away from the filter structure 100 in the first direction, has a battery hatch 5240 connected to the battery installation opening 4330. The battery hatch 5240 allows the battery pack assembly 5100 to enter and exit. The battery pack assembly 5100 is removably mounted within the battery compartment 5200, sequentially passing through the battery installation opening 4330 and the battery hatch 5240. When the battery pack assembly 5100 is installed within the battery compartment 5200 and not locked in position, it slides in engagement with the battery compartment 5200 in the first direction. This allows assembly and disassembly of the battery pack assembly 5100 by simply pushing or pulling it out, making operation more convenient.

[0113] See Figures 7 to 9 ,as well as Figure 11 In some embodiments, the inner wall of the battery compartment 5200 is constructed with a compartment slide groove 5210 extending along the first direction, and the battery pack assembly 5100 has a sliding plate 5110 extending along the first direction, and the sliding plate 5110 is slidably installed in the compartment slide groove 5210.

[0114] Specifically, the inner wall of the battery compartment 5200 is constructed with two spaced-apart ribs 5211 extending in a first direction, forming a compartment chute 5210 between the two ribs 5211. The battery pack assembly 5100 includes a battery shell 5140 wrapped around the battery pack 5150, with a sliding plate 5110 protruding from the outer wall of the battery shell 5140. When the battery pack assembly 5100 is pushed or pulled, the sliding plate 5110 slides in the first direction within the compartment chute 5210 to provide guidance and position control, making the assembly and disassembly of the battery pack assembly 5100 smoother.

[0115] In other embodiments, the positions of the sliding plate 5110 and the cabin slide groove 5210 may be interchanged, or other conventional sliding fitting structures may be selected.

[0116] See Figures 7 to 9 ,as well as Figure 11 In some embodiments, one of the battery compartment 5200 and the battery pack assembly 5100 is provided with a battery pack locking slot 5220, and the other is provided with a battery pack locking block 5120 that elastically snaps into the battery pack locking slot 5220, and a battery pack release button 5130 connected to the battery pack locking block 5120. The battery pack release button 5130 is configured to be operably pressed to drive the battery pack locking block 5120 to exit the battery pack locking slot 5220.

[0117] In the embodiment shown in the accompanying drawings, the battery compartment 5200 is provided with a battery pack locking slot 5220, the battery pack assembly 5100 is provided with a battery pack locking block 5120 that elastically engages the battery pack locking slot 5220, and a battery pack release button 5130 connected to the battery pack locking block 5120. Specifically, the battery pack locking slot 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. The battery pack release button 5130 is elastically connected to the battery pack housing 5140 via 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 via the battery pack release button 5130, thereby engaging the battery pack locking block 5120 with the battery pack locking slot 5220. When the battery pack release button 5130 is pressed, the battery pack locking block 5120 overcomes the elastic force of the battery pack locking elastic member 5160 and moves out of the battery pack locking slot 5220. This locking structure securely and stably locks the battery pack assembly 5100 within the battery compartment 5200, ensuring stable power supply. Furthermore, when the battery pack assembly 5100 needs to be disassembled, it can be quickly and conveniently installed.

[0118] See Figure 7 、 Figure 8 、 Figure 10 and Figure 11 In some embodiments, the body 10 includes a circuit board 5300 installed in the casing 4000, and 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 passes through the compartment wall of the battery compartment 5200 and contacts and conducts with the battery pack assembly 5100.

[0119] Specifically, the circuit board 5300's body 5310 is fixedly mounted on the outer wall of the battery compartment 5200, and the coupler 5320 protrudes from the body 5310. The battery compartment 5200 is provided with a through-hole 5230 for the coupler. The coupler 5320 extends through the through-hole 5230 into the interior of the battery compartment 5200 and contacts and connects to the battery pack assembly 5100 installed in the battery compartment 5200.

[0120] Preferably, in some embodiments, the circuit board 5300 includes a flexible coupler cap 5330 connected to the board body 5310 and sleeved on the outside of the coupler 5320 , and the flexible coupler cap 5330 is inserted into the coupler through hole 5230 .

[0121] The flexible coupler cap 5330 is made of a flexible material such as silicone or rubber, and is inserted into the coupler through hole 5230 and has an interference fit therewith, thereby protecting the coupler 5320 from being easily damaged by collision.

[0122] See Figure 10 and Figure 11 In some embodiments, the flexible coupler cap 5330 has a protruding brim 5331 at one end close to the circuit board 5300 , and the brim 5331 blocks the end wall of the coupler through hole 5230 close to the circuit board 5300 .

[0123] Specifically, from the perspective of the accompanying drawings, the top of the flexible coupler cap 5330 has an outwardly protruding brim 5331, which blocks the top end wall of the coupler through-hole 5230. This prevents the flexible coupler cap 5330 from falling downward by blocking the brim 5331 against the end wall of the coupler through-hole 5230. Furthermore, this effectively seals the coupler through-hole 5230, preventing dust from reaching the surface of the circuit board 5300 through the coupler through-hole 5230 and causing damage when the battery pack assembly 5100 is not installed.

[0124] See Figure 3 、 Figure 7 and Figure 11 In some embodiments, the size of the battery hatch 5240 gradually increases in the first direction away from the filter structure 100. This configuration allows the entrance end of the battery hatch 5240 to be larger, making it easier for users to remove and install the battery pack assembly 5100 from this location.

[0125] Further, in some embodiments, in the orientation along the first direction and away from the filtering structure 100 , the battery compartment 5200 is inclined toward the negative pressure motor assembly 200 along the second direction close to the compartment wall of the negative pressure motor assembly 200 .

[0126] Specifically, in Figure 7 From this perspective, the bottom wall of the battery compartment 5200 extends downward at an angle. The user can press the battery pack release button 5130 with the thumb, and at the same time use the other four fingers to lift the battery pack assembly 5100 from the bottom for disassembly and assembly. Disassembly and assembly can be easily completed with one hand, which is relatively convenient. In the battery compartment 5200, except for the bottom wall, other areas are not arranged in an inclined extension manner. This can minimize the size of the battery compartment 5200 and thus reduce the space it occupies in the housing 4000. Of course, in other embodiments, the battery compartment opening 5240 can also be directly set to a trumpet shape with a small inside and a large outside.

[0127] See Figure 3 、 Figure 4 and Figure 6In some embodiments, the housing 4000 includes a grid plate 4110, which divides the inner cavity of the housing 4000 into a first installation cavity 4310 and a second installation cavity 4320 arranged along a first direction, and the grid plate 4110 has an air passage 4111 connecting 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 (battery pack assembly 5100) are installed in the second installation cavity 4320.

[0128] Specifically, the housing base 4100 includes a grid plate 4110, which is hollowed out to form an air passage 4111. The grid plate 4110 can guide and concentrate the airflow, so that the airflow discharged from the filter structure 100 to the first installation cavity 4310 passes through the air passage 4111 more concentratedly into the second installation cavity 4320, and thus flows more concentratedly into the negative pressure motor assembly 200, thereby reducing fluid loss and improving suction efficiency.

[0129] See Figure 3 、 Figure 4 and Figure 6 In some embodiments, the end of the first installation cavity 4310 away from the second installation cavity 4320 along the first direction has a first suction port 4340 for fluid to flow in, the end of the filter structure 100 away from the second installation cavity 4320 along the first direction has a first ash inlet 1111 connected to the first suction port 4340, and the end of the filter structure 100 close to the second installation cavity 4320 along the first direction has a first air outlet channel 1113 connected to the air passage 4111.

[0130] Specifically, the negative pressure motor assembly 200 includes a motor cover structure 2000 and a negative pressure motor 300 installed in the motor cover structure 2000. The specific structure of the motor cover structure 2000 will be described in detail in the subsequent embodiments. The negative pressure motor 300 provides suction force, and the external airflow, along with the garbage, is sucked into the housing 4000 through the first suction port 4340, and enters the filter structure 100 from the first ash inlet 1111 for filtration and separation. The garbage is retained in the filter structure 100, and the clean airflow is discharged from the first air outlet channel 1113 to the first installation cavity 4310, and then sucked into the second installation cavity 4320 from the air passage 4111. It is sucked into the interior of the motor from the negative pressure motor air inlet 3100 of the negative pressure motor 3000, and after being discharged from the negative pressure motor 3000, it is discharged to the external environment from the first outlet 4350 opened on the housing 4000.

[0131] In the embodiment shown in the accompanying drawings, the filter structure 100 is a dust cup structure 1000. In other embodiments, the filter structure 100 may also be a filter bag. The following description will primarily use the filter structure 100 shown in the accompanying drawings as an example of a dust cup structure 1000. The specific structure within the dust cup structure 1000 will be described in detail in subsequent embodiments.

[0132] See Figure 3 、 Figure 4 and Figure 6 In some embodiments, the housing 4000 has a first outlet 4350 connected to the second installation cavity 4320 and used for fluid discharge at one end along the third direction, and a second HEPA 5410 and an aromatherapy component 5420 are installed at the first outlet 4350, wherein the third direction is perpendicular to the first direction and the second direction.

[0133] Specifically, the position of the first outlet 4350 is opposite to the air outlet of the negative pressure motor assembly 200, so that the airflow can be discharged smoothly. In the above embodiment, by installing the second Hepa 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 installing the aromatherapy component 5420 at the first outlet 4350, the discharged airflow can be scented to purify the external environment and improve the user experience. In other embodiments, the first outlet 4350 can also be set at both ends of the casing 4000 along the third direction, and the two first outlets 4350 are both installed with the second Hepa 5410 and the aromatherapy component 5420.

[0134] See Figure 2 、 Figure 6 and Figure 12 In some embodiments, the first installation cavity 4310 is open on the side away from the surface to be cleaned along the second direction, the filter structure 100 closes the opening of the first installation cavity 4310, and the outer wall of the filter structure 100 along the second direction away from the surface to be cleaned constitutes a part of the outer wall of the body 10.

[0135] From the perspective of the accompanying drawings, the top of the first installation cavity 4310 is open. After the filter structure 100 is installed in the first installation cavity 4310, the opening at the top of the first installation cavity 4310 is sealed. The top shape of the filter structure 100 is configured to match the outer wall of the housing 10, that is, the housing top cover 4200. After installation, it forms a part of the outer wall of the housing 10. This eliminates the need for a separate shell-like structure at this location, simplifying the structure. In the embodiment shown in the accompanying drawings, the top wall of the filter structure 100 is configured to be a quarter sphere to match the shape of the housing top cover 4200.

[0136] See Figure 4 、 Figure 12 、 Figure 28 and Figure 31In some embodiments, one of the cavity wall of the first installation cavity 4310 and the filter structure 100 (dust cup structure 1000) is provided with a bottom cover positioning protrusion 4311, and the other is provided with a bottom cover positioning groove 1520, and the bottom cover positioning protrusion 4311 is inserted into the bottom cover positioning groove 1520.

[0137] In the embodiment shown in the accompanying drawings, a bottom cover positioning protrusion 4311 is provided on the bottom wall of the first installation cavity 4310, and a bottom cover positioning groove 1520 is provided at the bottom end of the filter structure 100 (dust cup structure 1000). When installing the filter structure 100 (dust cup structure 1000), the bottom cover positioning protrusion 4311 is inserted into the bottom cover positioning groove 1520 to facilitate positioning and quick installation. In other embodiments, the positions of the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520 can be interchanged.

[0138] Preferably, a plurality of sets of matching 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 installation cavity 4310.

[0139] See Figure 4 、 Figure 12 and Figure 30 In some embodiments, one of the cavity wall of the first installation cavity 4310 and the filter structure 100 is provided with a cup machine hook 1131 , and the other is provided with a cup machine positioning groove 4312 , and the cup machine hook 1131 is hung in the cup machine positioning groove 4312 .

[0140] In the embodiment shown in the accompanying drawings, a cup dispenser positioning groove 4312 is recessed into the wall of the first mounting cavity 4310, and a cup dispenser hook 1131 is protruding from the filter structure 100 (dust cup structure 1000). The cup dispenser hook 1131 is hooked into the cup dispenser positioning groove 4312, thereby restricting the horizontal movement of the filter structure 100 (dust cup structure 1000) after installation in the first mounting cavity 4310, thereby enhancing position retention. In other embodiments, the positions of the cup dispenser hook 1131 and the cup dispenser positioning groove 4312 can be interchanged.

[0141] Preferably, multiple sets of matching cup machine hooks 1131 and cup machine positioning grooves 4312 are provided to further optimize the limiting effect.

[0142] See 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 close to the surface to be cleaned along the second direction, and the cup machine hook 1131 is arranged at one end of the filter structure 100 close to the second installation cavity 4320 along the first direction, and in the second direction, the cup machine hook 1131 is located on the side of the bottom cover positioning groove 1520 away from the surface to be cleaned.

[0143] Specifically, the bottom cover positioning groove 1520 is provided at the bottom of the filter structure 100 (dust cup structure 1000), and the cup machine hook 1131 is provided on the side of the filter structure 100 (dust cup structure 1000), near the top. This arrangement allows the top and bottom ends of the filter structure 100 (dust cup structure 1000) to be positioned by the cooperation of 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, thereby optimizing the positioning effect. Furthermore, after installation, the filter structure 100 (dust cup structure 1000) is more stable and less likely to shake or shift.

[0144] See Figure 4 、 Figure 12 and Figure 27 In some embodiments, one of the cavity wall of the first installation cavity 4310 and the filter structure 100 is provided with an upper cover snap-fitting groove 4313, and the other is provided with an upper cover protrusion 1410 elastically snapped into the upper cover snap-fitting groove 4313, and an upper cover rotating buckle 1420 connected to the upper cover protrusion 1410, and the upper cover rotating buckle 1420 is configured to move operably to drive the upper cover protrusion 1410 to exit the upper cover snap-fitting groove 4313.

[0145] In the embodiment shown in the accompanying drawings, the side wall of the first installation cavity 4310 is recessed with an upper cover snap-fitting groove 4313, and the filter structure 100 (dust cup structure 1000) has an upper cover protrusion 1410 that is elastically snapped into the upper cover snap-fitting groove 4313, and an upper cover rotating buckle 1420 connected to the upper cover protrusion 1410.

[0146] Specifically, the dust cup structure 1000 includes a dust cup upper cover 1400. An elastic member is connected between the upper cover protrusion 1410 and the dust cup upper cover 1400. The elastic force of the elastic member enables the upper cover protrusion 1410 to elastically snap into the upper cover snap-fit ​​groove 4313. The dust cup upper cover 1400 is rotatably connected to the upper cover rotating buckle 1420. By rotating the upper cover rotating buckle 1420 so that it abuts against the upper cover protrusion 1410, the upper cover protrusion 1410 can be pushed out of the upper cover snap-fit ​​groove 4313. For example, the user buckles the upper cover rotating buckle 1420 and rotates it clockwise, which pushes the upper cover protrusion 1410 to move away from the upper cover engaging groove 4313 until it is released from the upper cover engaging groove 4313; then the user applies upward force to lift the dust cup structure 1000 via the dust cup handle 1430, so that the dust cup structure 1000 can be completely removed from the first installation cavity 4310. During installation, the user buckles the upper cover rotating buckle 1420, places the dust cup structure 1000 into the first installation cavity 4310, and then releases the hand from the upper cover rotating buckle 1420. The upper cover protrusion 1410 can then be snapped into the upper cover engaging groove 4313 under the action of the rebound force of the elastic member, thus completing the locking.

[0147] See Figure 1 、 Figure 5 and Figure 12 In some embodiments, the housing 4000 is provided with a hanging slot 4210 for hanging the cleaning module 20.

[0148] Specifically, a hanging groove 4210 is provided at one end of the casing top cover 4200 away from the filter structure 100 (dust cup structure 1000) along the first direction. After the horizontal cleaning device is used, the holding assembly 8100 of the cleaning module 20 can be hung on the hanging groove 4210 for easy storage, and at this time the placement stability of the entire device is also higher.

[0149] As previously mentioned, in the working state, the grip assembly 8100 is configured to be operably moved on the surface to be cleaned, so as to drive the body 10 to move on the surface to be cleaned via the rollers through the flexible tube 8300. However, in the non-working state, when moving the horizontal cleaning device over a long distance, the body 10 cannot be moved solely by moving the grip assembly 8100, because long-distance movement may scratch the surface to be cleaned. In this case, the user needs to operate the grip assembly 8100 with one hand and the handle assembly 6000 in the body 10 with the other hand to move the horizontal cleaning device; or, the user can hang the grip assembly 8100 on the hanging slot 4210 and then move the horizontal cleaning device as a whole.

[0150] See Figure 1The horizontal cleaning device provided in one embodiment of the present application includes the body 10 of any one of the aforementioned embodiments, and also includes a cleaning module 20. The cleaning module 20 includes a gripping assembly 8100, a floor brush assembly 8200 and a flexible tube 8300. One end of the gripping assembly 8100 is connected to the floor brush assembly 8200, and the other end is connected to the flexible tube 8300. The end of the flexible tube 8300 facing away from the gripping assembly 8100 is connected to the body 10.

[0151] When using the horizontal cleaning device for cleaning, the body 10 is placed on the surface to be cleaned and can move via the rollers arranged at its bottom end. The floor brush assembly 8200 is aimed at the area to be cleaned, and the negative pressure motor 2000 in the body 10 provides suction force. The external airflow carries the garbage and is sucked in from the suction port of the floor brush assembly 8200. It passes through the holding assembly 8100 and the flexible tube 8300 in turn and enters the filter structure 100 of the body 10 for filtration, and then is discharged from the body 10 after passing through the negative pressure motor 2000.

[0152] See Figure 1 In some embodiments, the gripping assembly 8100 includes a gripping handle 8110 and an extension rod 8120 disposed between the gripping handle 8110 and the floor brush assembly 8200 , and the extension rod 8120 is detachably connected to the floor brush assembly 8200 and / or the gripping handle 8110 .

[0153] The detachable connection between the extension rod 8120 and the floor brush assembly 8200 allows the floor brush assembly 8200 to be removed from the grip assembly 8100 for maintenance and replacement. The detachable connection between the extension rod 8120 and the grip handle 8110 allows the extension rod 8120 and the floor brush assembly 8200 to be removed from the grip handle 8110 for maintenance and replacement.

[0154] Preferably, the extension rod 8120 can be configured as a telescopic rod so as to be adjustable according to the user's needs. Figure 1 and Figure 13 In some embodiments, a local brush 8111 is rotatably connected to one end of the grip handle 8110 near the extension rod 8120. The local brush 8111 is relatively small in size and is suitable for cleaning smaller gaps and corners. The horizontal cleaning device can have two cleaning modes. In one mode, the local brush 8111 is rotated to Figure 1 In the other mode, the extension rod 8120 and the floor brush assembly 8200 are removed from the gripping handle 8110, and the local brush 8111 is rotated to Figure 13In the position shown, the local brush 8111 is used to clean some smaller gaps and corners. In this way, the horizontal cleaning device can be used in a wider range of scenarios.

[0155] See Figures 14 to 17 In some embodiments, one end of the extension rod 8120 is provided with a first electrical connection part 8121 for plugging and connecting with the grip handle 8110, and the other end is provided with a second electrical connection part 8122 for plugging and connecting with the floor brush assembly 8200. The first electrical connection part 8121 is a pin or a slot, and the second electrical connection part 8122 is a pin or a slot.

[0156] In the embodiment shown in the accompanying drawings, the first electrical connection portion 8121 is a pin, and the gripping handle 8110 is provided with a slot that plugs into the first electrical connection portion 8121. The second electrical connection portion 8122 is a slot, and the floor brush assembly 8200 is provided with a pin that plugs into the second electrical connection portion 8122. The first and second electrical connection portions 8121, 8122, ensure electrical continuity after the floor brush assembly 8200 is installed.

[0157] See Figures 14 and 15 In some embodiments, one of the floor brush assembly 8200 and the extension rod 8120 is provided with a floor brush locking cavity 8123, and the other is provided with a floor brush lock 8210 that is elastically snapped into the floor brush locking cavity 8123, and a floor brush button 8220 connected to the floor brush lock 8210. The floor brush button 8220 is configured to be operably pressed to drive the floor brush lock 8210 to exit the floor brush locking cavity 8123.

[0158] In the embodiment shown in the accompanying drawings, a floor brush lock cavity 8123 is provided on the extension rod 8120, and a floor brush lock 8210 is provided on the floor brush assembly 8200, which is elastically snapped into the floor brush lock cavity 8123, and a floor brush button 8220 is connected to the floor brush lock 8210. Specifically, the floor brush lock 8210 and the floor brush button 8220 are integrally formed or fixedly connected, and an elastic member is provided between at least one of the two and a component such as the housing of the floor brush assembly 8200. The elastic member uses its rebound force to elastically snap the floor brush lock 8210 into the floor brush lock cavity 8123. When the floor brush button 8220 is pressed, the rebound force of the elastic member is overcome, causing the floor brush lock 8210 to be released from the floor brush lock cavity 8123.

[0159] See Figures 16 and 17 In some embodiments, one of the holding handle 8110 and the extension rod 8120 is provided with a handle lock cavity 8112, and the other is provided with a handle lock 8124 that is elastically inserted 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 operably pressed to drive the handle lock 8124 to exit the handle lock cavity 8112.

[0160] In the embodiment shown in the accompanying drawings, the grip handle 8110 is provided with a handle lock cavity 8112, the extension rod 8120 is provided with a handle lock 8124 that elastically snaps into the handle lock cavity 8112, and a handle button 8125 connected to the handle lock 8124. The specific structure of these components is essentially the same as that of the floor brush lock 8210, floor brush button 8220, and floor brush lock cavity 8123, and will not be further described here.

[0161] See Figure 18 In some embodiments, the extension rod 8120 includes a separate fluid channel 8126 and a separate cable channel 8127. Specifically, both the fluid channel 8126 and the cable channel 8127 extend along the length of the extension rod 8120. The fluid channel 8126 allows airflow carrying debris to pass through, while the cable channel 8127 allows cables to pass through. By providing separate fluid channels 8126 and cable channels 8127, cables can be protected from damage caused by debris and airflow.

[0162] See Figure 20 In some embodiments, the end of the flexible tube 8300 facing away from the grip assembly 8100 is provided with a third electrical connection portion 8311 for plugging and conducting with the body 10, and the third electrical connection portion 8311 is a pin or a slot.

[0163] In the embodiment shown in the drawings, the third electrical connection portion 8311 is a pin, and the housing 10 is provided with a slot that plugs into and mates with the first electrical connection portion 8121. Through the third electrical connection portion 8311, electrical conduction between the cleaning module 20 and the housing 10 can be achieved.

[0164] See Figures 1 to 2 , a horizontal cleaning device provided in one embodiment of the present application includes a body 10 and a cleaning module 20. The cleaning module 20 includes a gripping assembly 8100, a floor brush assembly 8200 and a flexible tube 8300. One end of the gripping assembly 8100 is connected to the floor brush assembly 8200, and the other end is connected to the flexible tube 8300. The end of the flexible tube 8300 facing away from the gripping assembly 8100 is connected to the body 10. A display area 9000 for displaying target parameters is provided on the body 10. 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.

[0165] In the above embodiment, the display area 9000 is located on the body 10. During use, the body 10 is typically placed on the surface to be cleaned. Its overall height is lower than that of the cleaning module 20, allowing the user to observe the display in real time by simply lowering their head. Furthermore, in the second direction, the distance between the display area 9000 and the surface to be cleaned is greater than the distance between the other areas of the body 10 and the surface to be cleaned. This means that the display area 9000 is located at the point in the body 10 where it is most distant from the surface to be cleaned, and also at the point on the body 10 where it is most elevated. This arrangement prevents the display area 9000 from being obscured by other structures in the body 10, thus reducing the risk of blind spots. When the user lowers their head, the display area 9000 can be easily observed from any angle, allowing them to keep abreast of the device's current operating status. Furthermore, since the display area 9000 is located on the body 10 rather than the grip assembly 8100, there is no need to install wires within the flexible tube 8300 to electrically connect the display area 9000 to the body 10, as is required in the prior art. This reduces manufacturing costs.

[0166] See Figure 1 、 Figure 2 and Figure 19 In some embodiments, the body 10 includes a housing 4000 and a handle assembly 6000. The handle assembly 6000 protrudes from one end of the housing 4000 along the second direction away from the surface to be cleaned, and the display area 9000 is disposed on the handle assembly 6000. That is, when in use, the handle assembly 6000 protrudes from the top of the housing 4000. Placing the display area 9000 on the handle assembly 6000, which is the tallest part of the body 10, allows the display area 9000 to be positioned high and less easily obscured by other structures in the body 10. When the user lowers their head, they can easily see the display area 9000 from any angle, thereby providing a timely understanding of the current operating status of the device.

[0167] See Figure 1 、 Figure 2 and Figure 19 In some embodiments, the end surface of the handle assembly 6000 along the second direction away from the surface to be cleaned is the handle top surface 6210 , the handle top surface 6210 is an outwardly convex arc surface, and the display area 9000 is located at the center of the handle top surface 6210 .

[0168] Specifically, the handle top surface 6210 is convex and curved, so its center is the highest point on it. The display area 9000 is arranged there, so that the display area 9000 is at a high position. In other embodiments, the handle top surface 6210 can also be set to other shapes, as long as the display area 9000 is at its highest point on it.

[0169] See Figure 3 and Figure 19In some embodiments, the handle assembly 6000 includes a handle body 6100 and a handle cover 6200. The handle body 6100 is connected to the housing 4000. The handle cover 6200 is connected to one end of the handle body 6100 away from the housing 4000 along the second direction. A display notch 6220 is provided on the handle cover 6200, and the display area 9000 is located at the display notch 6220.

[0170] Furthermore, the handle assembly 6000 includes a display 6300, which is mounted between the handle body 6100 and the handle cover 6200 and is exposed through a display notch 6220. Specifically, the handle body 6100 is fixedly connected to the top of the housing cover 4200, and the handle cover 6200 is connected to the top of the handle body 6100. A hollow cavity is constructed between the handle cover 6200 and the handle body 6100 for mounting the display 6300. The top of the display 6300 is exposed through the display notch 6220 to form a display area 9000.

[0171] In some embodiments, the display 6300 is fixedly mounted on the display bracket 6400, and the display bracket 6400 is fixedly mounted on the handle body 6100. A transparent display window 6500 is also provided on the top of the display 6300, which is used to protect the display 6300 and allow the content displayed on the display 6300 to be exposed.

[0172] See Figure 3 and Figure 19 In some embodiments, the display area 9000 is used to display dust concentration. In some embodiments, the display area 9000 has a dust concentration display bar, which is divided into a first display segment and a second display segment of different colors. As the dust concentration increases, the first display segment increases and the second display segment decreases.

[0173] For example, the first display segment is red, and the second is blue. As dust concentration increases, the red portion of the dust concentration bar increases, while the blue portion decreases. Conversely, as dust concentration decreases, the blue portion of the dust concentration bar increases, while the red portion decreases. This allows users to more intuitively and quickly understand the current dirtiness of the surface being cleaned.

[0174] See Figure 3 、 Figure 20 and Figure 23 In some embodiments, the body 10 has a suction port assembly 7000 , the flexible tube 8300 is connected to the suction port assembly 7000 , and the suction port assembly 7000 includes a dust concentration detector 7100 , which is used to detect the dust concentration of the fluid flowing through the flexible tube 8300 .

[0175] Specifically, the suction port assembly 7000 is installed at the first suction port 4340. The airflow and garbage sent from the flexible tube 8300 pass through the suction port assembly 7000 and reach the first suction port 4340. The dust concentration detector 7100 detects the dust concentration of the fluid flowing through the flexible tube 8300 and displays it on the display area 9000, allowing the user to know the current dirtiness of the surface to be cleaned.

[0176] See Figure 3 、 Figure 20 and Figure 23 In some embodiments, the housing 10 includes a circuit board 5300 and a negative pressure motor 3000 for providing suction to the floor brush assembly 8200. The negative pressure motor 3000 and the dust concentration detector 7100 are both electrically connected to the circuit board 5300. The circuit board 5300 is capable of adjusting the suction power of the negative pressure motor 3000 based on the measured dust concentration. Specifically, the dust concentration detector 7100 detects the dust concentration of the fluid flowing through the flexible tube 8300 and feeds the detected dust concentration back to the circuit board 5300. The circuit board 5300 controls the display area 9000 to display the current dust concentration. Simultaneously, the circuit board 5300 adjusts the suction power of the negative pressure motor 3000 based on the current dust concentration to 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 improve the suction force. Conversely, when the dust concentration is too high, the suction power of the negative pressure motor 3000 is reduced to achieve energy saving.

[0177] See 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. 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, and the second dust concentration threshold can be a set lower limit. The first and second dust concentration thresholds can be set by the user or configured uniformly before shipment. When the dust concentration is between the first and second dust concentration thresholds, the current suction power of the negative pressure motor 3000 is assumed to meet both cleaning and energy conservation requirements. When the dust concentration is greater than the first dust concentration threshold, the current suction power of the negative pressure motor 3000 is assumed to be insufficient, potentially resulting in incomplete cleaning, and therefore the suction power needs to be increased. When the dust concentration is less than the second dust concentration threshold, the current suction power of the negative pressure motor 3000 is assumed to be excessive, which is not conducive to energy conservation, and therefore the suction power can be reduced.

[0178] See Figure 3In some embodiments, the circuit board 5300 controls the negative pressure motor 3000 to increase or decrease the suction power according to a preset ratio. Specifically, this ratio can be set by the user or configured uniformly at the factory. For example, the suction power may be increased or decreased by 20% of the current value. If the dust concentration still does not meet the standard after a single increase or decrease, the suction power will continue to increase or decrease in the same manner as above. This allows for fine-grained adjustment of the suction power.

[0179] See Figure 21 、 Figure 22 、 Figure 23 and Figure 25 In some embodiments, the flexible tube 8300 has a docking joint 8310 at one end facing away from the grip assembly 8100. The nozzle assembly 7000 includes a sleeve 7200. The docking joint 8310 and the sleeve 7200 are plugged together. The dust concentration detector 7100 includes an infrared emitting unit 7110 and an infrared receiving unit 7120 mounted on the sleeve 7200. The infrared emitting unit 7110 and the infrared receiving unit 7120 are respectively disposed at the radial ends of the sleeve 7200. Specifically, the nozzle assembly 7000 includes a nozzle housing 7300, and the sleeve 7200 is fixed to the nozzle housing 7300. The infrared emitting unit 7110 and the infrared receiving unit 7120 are both infrared paired tubes, and are respectively fixed to the radial ends of the sleeve 7200. The infrared rays emitted by the infrared emitting unit 7110 pass through the interior of the docking head 8310 and are received by the infrared receiving unit 7120. Depending on the dust concentration in the docking head 8310, the information received by the infrared receiving unit 7120 is also different, so that the current dust concentration value can be obtained accordingly.

[0180] See Figure 21 、 Figure 22 、 Figure 23 and Figure 25 In some embodiments, the docking joint 8310 is inserted into the sleeve 7200, and the infrared emitting unit 7110 and the infrared receiving unit 7120 are both installed on the outside of the sleeve 7200, and the sleeve 7200 is transparent. Specifically, the docking joint 8310 extends from the opening of the suction port shell 7300 and is inserted into the sleeve 7200. The sleeve 7200 is transparent and can be penetrated by infrared rays. Therefore, even if the infrared emitting unit 7110 and the infrared receiving unit 7120 are installed 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 joint 8310. In this way, the sleeve 7200 can be transparent or not.

[0181] See Figure 20 、 Figure 21 、 Figure 22 、 Figure 23 and Figure 25In some embodiments, the inner wall of the sleeve 7200 is provided with two docking bosses 7210 respectively arranged at its radial ends, and the end of the docking joint 8310 is provided with two docking notches 8312 respectively arranged at its radial ends. Each docking boss 7210 is inserted into the corresponding docking notch 8312, and the positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two docking bosses 7210 respectively.

[0182] Specifically, each docking boss 7210 snaps into a corresponding docking notch 8312 to limit the position of the docking head 8310 when inserted into the sleeve 7200. The infrared emitting unit 7110 and the infrared receiving unit 7120 are positioned corresponding to the two docking bosses 7210, respectively. That is, the infrared emitting unit 7110 is located outside the area of ​​the sleeve 7200 where one docking boss 7210 is located, and the infrared receiving unit 7120 is located outside the area where the other docking boss 7210 is located. Because the infrared emitting unit 7110 and the infrared receiving unit 7120 are positioned correspondingly to the two docking bosses 7210, and each docking boss 7210 fits into the corresponding docking notch 8312, the infrared rays emitted by the infrared emitting unit 7110 can precisely pass through the corresponding docking boss 7210 and enter the docking head 8310 through the corresponding docking notch 8312. After passing through the docking head 8310, the infrared rays pass through the corresponding docking boss 7210 through the other docking notch 8312 and are received by the infrared receiving unit 7120. In this way, the two docking bosses 7210 and the docking notches 8312 cooperate to achieve both infrared ray emission and reception.

[0183] See Figures 21 to 25 In some embodiments, a suction port seal 7400 is further provided between the butt joint 8310 and the sleeve 7200 to enhance sealing. Specifically, the seal 7400 includes an annular sealing ring 7410 and two lugs 7420 connected to the sealing ring 7410. The two lugs 7420 are located at radial ends of the sealing ring 7410, and each lug 7420 is provided with a seal retaining groove 7421. When the butt joint 8310 is inserted into the sleeve 7200 and the docking boss 7210 is engaged with the docking notch 8312, the inner wall of the butt joint 8310 protrudes inward relative to the inner wall of the docking boss 7210. The seal 7400 precisely fills this radial dimension difference between the inner wall of the butt joint 8310 and the inner wall of the docking boss 7210, ensuring smoother airflow through this area. A sealing member clamping block 7211 is protruded from the inner side of the docking boss 7210 , and the sealing member clamping block 7211 is clamped into the corresponding sealing member clamping groove 7421 to fix the position of the sealing member 7400 .

[0184] See Figure 20 and Figure 25In some embodiments, the end of the flexible tube 8300 facing away from the holding assembly 8100 has a docking joint 8310. One of the docking joint 8310 and the suction nozzle assembly 7000 is provided with a flexible tube locking cavity 7310, and the other is provided with a flexible tube lock 8313 that is elastically inserted 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 is configured to be operably pressed to drive the flexible tube lock 8313 to exit the flexible tube locking cavity 7310.

[0185] In the embodiment shown in the accompanying drawings, the nozzle housing 7300 of the nozzle assembly 7000 is provided with a flexible tube locking cavity 7310, and the docking joint 8310 is provided with a flexible tube locking buckle 8313 that elastically snaps into the flexible tube locking buckle cavity 7310, and a flexible tube button 8314 connected to the flexible tube locking buckle 8313. Specifically, the flexible tube button 8314 and the flexible tube locking buckle 8313 are integrally formed or fixedly connected. The flexible tube button 8314 and the housing and other structures of the docking joint 8310 are connected by an elastic member. The elastic member pushes the flexible tube button 8314 through its rebound force, which in turn pushes the flexible tube locking buckle 8313 to elastically snap into the flexible tube locking buckle cavity 7310. When the flexible tube button 8314 is pressed against the elastic force, the flexible tube locking buckle 8313 exits the flexible tube locking buckle cavity 7310. In this way, the flexible tube 8300 and the body 10 can be locked and unlocked.

[0186] See 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 used to drive the floor brush to rotate, and the display area 9000 is used to display the current of the floor brush motor.

[0187] In other embodiments, the floor brush motor may not be provided, but an impeller connected to the floor brush may be provided, and the fluid in the air duct drives the impeller to rotate, thereby driving the floor brush to rotate.

[0188] See Figure 1 and Figure 3 In some embodiments, the body 10 includes a circuit board 5300 and a negative pressure motor 3000 for providing suction force for the floor brush. The negative pressure motor 3000 and the floor brush motor are both electrically connected to the circuit board 5300. The circuit board 5300 can adjust the suction power of the negative pressure motor 3000 based on the current of the floor brush motor.

[0189] It can be understood that when the type of surface to be cleaned is different, or the roughness of the surface to be cleaned is different, the resistance of the floor brush assembly 8200 during suction is different, and the current of the floor brush motor is also different. For example, if the surface to be cleaned is made of materials such as carpet or sofa, the resistance of the floor brush assembly 8200 during suction will be greater, and accordingly, the current of the floor brush motor will be greater; if the surface to be cleaned is a floor, the resistance of the floor brush assembly 8200 during suction will be smaller, and accordingly, the current of the floor brush motor will be smaller. For another example, for the same type of surface to be cleaned, the greater the roughness, the greater the resistance of the floor brush assembly 8200 during suction, and the greater the current of the floor brush motor. It can be understood that when the current of the floor brush motor fed back to the circuit board 5300 is too large, it means that the current suction resistance is too large and it is more difficult for the user to use it. At this time, it is necessary to appropriately reduce the suction power of the negative pressure motor 3000 to reduce the suction resistance; when the current of the floor brush motor fed back to the circuit board 5300 is too small, it means that the current suction resistance is too small, and the floor brush assembly 8200 may slip on the surface to be cleaned. At this time, it is necessary to appropriately increase the suction power of the negative pressure motor 3000 to increase the suction resistance.

[0190] See Figure 1 and Figure 3 In some embodiments, when the current of the floor 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 floor brush motor is no greater than the first current threshold; when the current of the floor 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 floor brush motor is no 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 configured uniformly before leaving the factory. When the current of the floor brush motor is between the first current threshold and the second current threshold, the default is that the suction resistance brought by the current suction power of the negative pressure motor 3000 is relatively appropriate, the user can save effort when cleaning and the floor brush assembly 8200 is not easy to slip; when the current of the floor brush motor is greater than the first current threshold, the default is 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 floor brush motor is less than the second current threshold, the default is that the current suction power of the negative pressure motor 3000 is too small and the suction power needs to be increased.

[0191] See Figure 1 and Figure 3In some embodiments, the circuit board 5300 controls the negative pressure motor 3000 to increase / decrease the suction power according to a preset ratio. Specifically, this ratio can be set by the user or configured uniformly at the factory. For example, if the suction power is increased / decreased by 20% of the current value, and if the current of the brush motor still exceeds the first current threshold / second current threshold after a single increase / decrease, the suction power is further decreased / increased in the same manner as above, thus achieving fine-grained adjustment of the suction power.

[0192] See Figure 1 and Figure 3 In some embodiments, the floor brush assembly 8200 includes a floor brush, and the display area 9000 has a floor brush blocking indicator for indicating that the floor brush is blocked. In this way, the user can be reminded to clean the floor brush in time when the floor brush is blocked by hair or the like.

[0193] In some embodiments, the housing 10 includes a filter structure 100, and the display area 9000 has a filter structure blockage indicator for indicating that the filter structure 100 is blocked. In this way, when the filter structure 100 is blocked, the user can be promptly reminded to empty the dust and clean it.

[0194] See Figures 30 to 39 As shown, a dust cup structure 1000 for a vacuum cleaner provided in an embodiment of the present application includes a cup body 1100 and an ash throwing unit 1300. The cup body 1100 is constructed with a first ash inlet 1111 and an ash storage cavity 1112. A cyclone separation unit 1200 is provided in the cup body 1100. The cyclone separation unit 1200 is provided with a cyclone channel 1211 connected to the first ash inlet 1111, so that the solid mixture enters the cyclone separation through the first ash inlet 1111. From the channel; one of the ash-flinging unit 1300 and the cyclone separation unit 1200 is provided with a first snap-fitting rib 1221, and the other is provided with a first snap-fitting groove 1314 for snapping with the first snap-fitting rib 1221; the ash-flinging unit 1300 is constructed with an ash-flinging port 1321 connecting the cyclone channel 1211 and the ash storage chamber 1112, and the solid mixture in the cyclone channel 1211 enters the ash storage chamber 1112 through the ash-flinging port 1321 under the action of centrifugal force.

[0195] Specifically, the ash throwing unit 1300 and the cyclone separation unit 1200 are each formed as an independent part. The ash throwing unit 1300 is detachably fixed to the cyclone separation unit 1200 by snapping together the first snap rib 1221 and the first snap groove 1314. The ash throwing port 1321 protrudes from the outer surface of the cyclone outer wall 1220, so that the fixed mixture in the cyclone channel 1211 can enter the ash storage chamber 1112 through the ash throwing port 1321, so that the garbage can be stably stored temporarily in the ash storage chamber 1112. The connection and fixation of the ash throwing unit 1300 is simpler and more reliable, reducing the complexity of the process. Unlike the method in which the ash-fling unit 1300 and the cyclonic separation unit 1200 are connected via the first snap-fitting rib 1221 and the first snap-fitting groove 1314, in other embodiments, the ash-fling unit 1300 and the cyclonic separation unit 1200 may also be snap-fitted via the second connecting portion 1222 and the second snap-fitting rib 1316, thereby achieving a detachable connection between the ash-fling unit 1300 and the cyclonic separation unit 1200. Specifically, the cyclonic separation unit 1200 is provided with the second connecting portion 1222, and the ash-fling unit 1300 is provided with the second snap-fitting rib 1316 for snapping with the second connecting portion 1222. Alternatively, the ash-fling unit 1300 may be provided with the second connecting portion 1222, and the cyclonic separation unit 1200 may be provided with the second snap-fitting rib 1316 for snapping with the second connecting portion 1222. The structures of the second connecting portion 1222 and the second snap-fitting rib 1316 will be described in detail below.

[0196] See Figures 30 to 39 As shown, in one embodiment, the cyclone separation unit 1200 includes a cyclone outer wall 1220 and a cyclone inner wall 1210 disposed within the cyclone outer wall 1220. The cyclone outer wall 1220 and the cyclone inner wall 1210 cooperate to enclose a cyclone channel 1211. A cyclone cone 1230 is connected to the cyclone inner wall 1210. The cyclone cone 1230 has a first fluid channel 1231 configured therein, which communicates with the air inlet of the vacuum cleaner's negative pressure motor. The cyclone cone 1230 is provided with a plurality of first grids 1232 along its circumference. The first grids 1232 can prevent solid mixtures from entering the first fluid channel 1231. The through slots 1233 between adjacent first grids 1232 connect the cyclone channel 1211 and the first fluid channel 1231. It is understood that the first grids 1232 are composed of a plurality of through slots 1233. Specifically, in order to ensure a higher negative pressure in the cyclone channel 1211, that is, the fluid loss of the entire system is small, the length of the through groove 1233 along the fluid flow direction is 28 mm, the groove width at the bottom of the through groove 1233 is 3 mm, and the groove width at the top of the through groove 1233 is 1.5 mm.

[0197] Under the action of the negative pressure motor, large particles of garbage have a greater centrifugal force and move in a circular motion along the outer wall 1220 of the cyclone. When they move to the ash outlet 1321, they fly out of the cyclone channel 1211. Small particles of garbage are blocked by the first grid 1232 at the cyclone cone 1230 and rebound. They then move in a circular motion and are thrown out of the ash outlet 1321 into the ash storage chamber 1112.

[0198] See Figures 30 to 34 As shown, in one embodiment, the cyclone channel 1211 is arranged in a spiral along the circumference of the cyclone cone 1230; the first grid 1232 is at a higher level than the first ash inlet 1111. The first ash inlet 1111 can be located below the first grid 1232 and provided with a spiral upward channel, so that the mixed fluid is drawn upward by the suction force of the negative pressure motor through the spiral upward channel.

[0199] See Figures 30 to 39 As shown, in one embodiment, the cyclone outer wall 1220 is shaped like an arc, and the center of curvature of the cyclone outer wall 1220 coincides with the center of curvature of the cyclone cone 1230. For example, in this embodiment, the cyclone outer wall 1220 is shaped like a circle with a constant diameter that is concentric with the cyclone cone 1230. This ensures that the fluid undergoes high-speed circular motion within the cyclone channel 1211, thereby generating a large centrifugal force, which is beneficial for separating solid mixtures such as dust from the fluid. At the same time, the circular shape of the cyclone outer wall 1220 also facilitates injection molding. The diameter of the cyclone inner wall 1210 can be adjusted according to the speed of the fluid in the height direction. In other embodiments, the cyclone outer wall 1220 can be a cylinder with a variable diameter, and its shape can be elliptical or conical, etc.

[0200] See Figures 30 to 32 As shown, 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 cyclone outer wall 1220 is L1, the minimum distance between the cyclone outer wall 1220 and the end of the ash-shedding unit 1300 (i.e., the outermost side of the ash-shedding opening 1321) is L2, and the maximum distance between the cyclone outer wall 1220 and the end of the ash-shedding 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 = 13 mm, and L3 = 16 mm.

[0201] See Figures 32 to 39 As shown, in one embodiment, the level of the ash outlet 1321 is higher than the level of the first grid 1232 , so that the particles doing circular motion lose centripetal force when the speed is fastest, and then fly out along the ash outlet 1321 to the ash storage chamber 1112 .

[0202] See Figures 32 to 39As shown, in one embodiment, the ash removal unit 1300 includes a main body 1310 and an ash blocking portion 1320 disposed on the main body 1310. The main body 1310 is used to connect to the cyclone outer wall 1220, and the ash blocking portion 1320 extends relative to the main body 1310 in a direction toward the ash storage chamber 1112. When the cyclone passage 1211 is under negative pressure and there is a high-speed rotating airflow, the gas in the ash storage chamber 1112 will be attracted to carry garbage back into the cyclone passage 1211, thereby affecting the separation efficiency. By providing the ash blocking portion 1320 to extend relative to the main body 1310 in a direction toward the ash storage chamber 1112, the ash blocking portion 1320 has a certain length to prevent dust in the ash storage chamber 1112 from flowing back.

[0203] See Figures 32 to 39 As shown, in one embodiment, the cyclone outer wall 1220 is provided with a first snap-fit ​​rib 1221; the main body 1310 is provided with a first connecting portion 1311, which includes a first branch segment 1312 and two second branch segments 1313 connected to both sides of the first branch segment 1312. The first branch segment 1312 and the two second branch segments 1313 cooperate to enclose a first snap-fit ​​groove 1314; the first branch segment 1312 abuts the top of the first snap-fit ​​rib 1221. This arrangement achieves a snap-fit ​​fixation between the dust-shedding unit 1300 and the cyclone outer wall 1220, and makes the connection between the two more convenient.

[0204] See Figures 32 to 39 As shown, in one embodiment, the cyclone outer wall 1220 extends a second connecting portion 1222 in the direction toward the ash storage chamber 1112, and the second connecting portion 1222 includes a third branch segment 1223 and a fourth branch segment 1224 that are vertically connected, and the third branch segment 1223 and the fourth branch segment 1224 cooperate to 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 segment 1223, and the second clamping rib 1316 is clamped in the second clamping groove 1225.

[0205] See Figures 32 to 39As shown, in one embodiment, the second connecting portion 1222 includes a fifth branch segment 1226 connected to the bottom of the fourth branch segment 1224. The main body 1310 extends toward the ash storage chamber 1112 to form a third connecting portion 1317. The third connecting portion 1317 is provided with a second opening slot 1318 and a third snap-fitting rib 1319 located at the bottom of the second opening slot 1318. The fourth branch segment 1224 snaps into the second opening slot 1318, and the third snap-fitting rib 1319 abuts against the bottom of the fifth branch segment 1226. When the ash-shedding unit 1300 moves downward in the direction of gravity, the multiple snap-fitting ribs snap into engagement with the corresponding snap-fitting slots, thereby securely fixing the ash-shedding unit 1300 to the cyclone outer wall 1220 and preventing the ash-shedding unit 1300 from tilting outward relative to the cyclone outer wall 1220.

[0206] See Figure 2 、 Figure 12 、 Figure 26 and Figure 27 As shown, in one embodiment, the dust cup structure 1000 further includes a dust cup cover 1400 rotatably connected to the cup body 1100, and the dust cup cover 1400 abuts against the dust throwing unit 1300. Specifically, the dust cup cover 1400 is provided with a cover lock 1450, which is used to engage with the cup body 1100. By turning the cover lock 1450, the dust cup cover 1400 can be opened, thereby pouring out the dust in the dust storage chamber 1112 and achieving deep cleaning of the cup body 1100. Furthermore, the dust cup cover 1400 is provided with a cover notch 1440, and the cover lock 1450 is located in the cover notch 1440, so that the user can easily operate the cover lock 1450 through the cover notch 1440, thereby conveniently taking the dust cup structure 1000; at the same time, the dust cup structure 1000 can also be docked with the machine body 10 through the cover notch 1440.

[0207] See Figure 2 、 Figure 12 、 Figure 26 and Figure 27 As shown, in one embodiment, the dust cup upper cover 1400 is elastically connected to the upper cover protrusion 1410, that is, an upper cover elastic member is provided between the dust cup upper cover 1400 and the cup body 1100, and the upper cover protrusion 1410 is maintained in a protruding state through the action of the upper cover elastic member; the body of the vacuum cleaner is provided with an upper cover clamping groove 4313 for clamping with the upper cover protrusion 1410, and the dust cup structure 1000 is fixed in the upper and lower positions relative to the body through the clamping and fixing of the upper cover protrusion 1410 and the upper cover clamping groove 4313.

[0208] See Figure 2 、 Figure 12 、 Figure 26 and Figure 27As shown, the dust cup upper cover 1400 is rotatably connected to the upper cover rotating buckle 1420. The upper cover rotating buckle 1420 can abut against the upper cover protrusion 1410 to drive the upper cover protrusion 1410 out of the upper cover engaging slot in a direction away from the upper cover engaging slot. For example, the user buckles the upper cover rotating buckle 1420 and rotates it clockwise, which in turn pushes the upper cover rotating buckle 1420 back to move the upper cover protrusion 1410 away from the upper cover engaging slot until the upper cover protrusion 1410 is released from the upper cover engaging slot. The user then applies upward force to lift the dust cup structure 1000 via the dust cup handle 1430, thereby removing the dust cup structure 1000 from the main body. During installation, after the dust cup structure 1000 is placed into the main body, the user releases the dust cup structure 1000 from the main body, and the upper cover protrusion 1410 is engaged with the upper cover engaging slot under the action of the upper cover elastic member.

[0209] See Figures 33 to 39 As shown in one embodiment, the cup body 1100 is provided with a first outlet channel 1113 connected to the first fluid channel 1231. The first outlet channel 1113 has a first outlet port, which is equipped with a first HEPA 1114. The first outlet channel 1113 is trumpet-shaped. At least a portion of the cyclone separation unit is located above the first outlet channel 1113, meaning that their horizontal projections at least partially overlap. After passing through the first grid 1232 of the cyclone cone 1230, the airflow moves downward along the first fluid channel 1231, entering the first outlet channel 1113, and is filtered by the first HEPA 1114 at the end of the first outlet channel 1113. Small particles that pass through the first grid 1232 are blocked and filtered by the first HEPA 1114, preventing them from entering the negative pressure motor and damaging components such as the impeller, rotor, and circuit board. The first HEPA 1114 is made of a material with a certain degree of air permeability. Generally, a larger HEPA area reduces losses to the entire fluid system. In order to ensure that the first Hepa 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 groove 1233) is 1163.8 mm2. The Hepa filtration area is 7349.43 mm2. And in order to control the size of the whole machine to the minimum, the negative pressure motor can be set behind 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 a smooth flow of air, the first air outlet channel 1113 is set to be trumpet-shaped, with the opening facing the first Hepa 1114.

[0210] In order to reduce the volume of the dust cup structure 1000, the projections of the cyclone channel 1211 and the first air outlet channel 1113 on the horizontal plane partially overlap, and the cyclone channel 1211 is embedded in the first air outlet channel 1113. Because the cyclone channel 1211 is circular, and the inner wall of the circular air duct is smooth, it can reduce turbulence and vortexes in the airflow, making the airflow more stable. Compared with air ducts of other shapes, the circular air duct has lower friction resistance, which can reduce energy loss. In addition, the circular air duct can evenly distribute the airflow on the cross section, reduce the unevenness of the local airflow velocity, and help maintain a stable airflow so that it can smoothly enter the first air outlet channel 1113. In order to enable the fluid to obtain greater centrifugal force in the cyclone channel 1211, the spiral ascending channel needs to be as long as possible. For example, in this embodiment, the spiral angle is 360 degrees, that is, one circle. In other embodiments, the spiral channel can be 720 degrees or larger, so that the cyclone channel 1211 can circle several more times. At the same time, because the cyclone channel 1211 is spirally upward, a gap will appear at the bottom of the cyclone channel 1211, and this gap will serve as a part of the first air outlet channel 1113, which can better redirect the fluid and save space.

[0211] See Figure 30 As shown, in one embodiment, the body of the vacuum cleaner is provided with an anti-leakage elastic member and an anti-leakage member 1122 connected to the anti-leakage elastic member. The anti-leakage elastic member is used to drive the anti-leakage 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 Hepa 1114 is provided with an anti-leakage blocking piece 1115. The anti-leakage blocking piece 1115 is used to abut against the anti-leakage member 1122. That is, when the first Hepa 1114 is installed in the body, the anti-leakage blocking piece 1115 will press the anti-leakage member 1122, causing the anti-leakage member 1122 to retract relative to the cup body 1100. The dust cup structure 1000 and the body no longer interfere with each other, thereby enabling the normal assembly of the dust cup structure 1000.

[0212] In one embodiment, the dust cup structure 1000 also includes 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 to lock the dust cup bottom cover 1500 and the cup body 1100; the bottom cover lock 1510 is configured to be operably moved 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.

[0213] Specifically, one of the dust cup bottom cover 1500 and the vacuum cleaner body is provided with a bottom cover positioning protrusion 4311, and the other is provided with a bottom cover positioning groove 1520 for engaging with the bottom cover positioning protrusion 4311. For example, in this embodiment, the bottom cover positioning groove 1520 is provided on the dust cup bottom cover 1500, and the bottom cover positioning protrusion 4311 is provided in the vacuum cleaner body. The engagement between the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520 positions the dust cup structure 1000. In other embodiments, the bottom cover positioning protrusion 4311 is also provided on the dust cup bottom cover 1500, and the bottom cover positioning groove 1520 is provided in the vacuum cleaner body.

[0214] See Figure 2 、 Figure 12 、 Figure 26 and Figure 27 As shown, further, the present application also provides a vacuum cleaner comprising a body and a dust cup structure 1000 as described above, detachably connected to the body; the body is provided with a first suction port connected to a first ash inlet 1111; one of the cup body 1100 and the body is provided with a cup machine hook 1131, and the other is provided with a cup machine positioning groove for engaging with the cup machine hook 1131. For example, in this embodiment, the cup body 1100 is provided with the cup machine hook 1131, and the body is provided with the cup machine positioning groove. The cup machine hook 1131 can be provided at the top end of the dust cup structure 1000, while the bottom cover positioning groove 1520 of the aforementioned embodiment can be provided at the bottom end of the dust cup structure 1000. By providing fixing structures at both the top and bottom ends, the connection between the dust cup structure 1000 and the body is more stable and reliable. It is understood that in other embodiments, the cup body 1100 can also be provided with the cup machine positioning groove, while the body is provided with the cup machine hook 1131.

[0215] See Figures 1 to 3 and Figure 19 In some embodiments, the body 10 includes a housing 4000 and a handle assembly 6000. The dust cup structure 1000 and the negative pressure motor and other components are installed in the housing 4000. The handle assembly 6000 is protruding from the end of the housing 4000 that is away from the surface to be cleaned. That is, when in use, the handle assembly 6000 is protruding from the top of the housing 4000. In this way, the handle assembly 6000 constitutes the first part of the outer surface of the vacuum cleaner. The dust cup cover 1400 of the dust cup structure 1000 is a quarter circle, so that when installed in the housing 4000, it can constitute the second part of the outer surface of the vacuum cleaner. The housing 4000 constitutes the third part of the outer surface of the vacuum cleaner. This makes the outer surface of the vacuum cleaner relatively flat and beautiful, saves more space, and is convenient for users to operate. Furthermore, the housing 4000 has a battery installation port 4330 at one end thereof away from the dust cup structure 1000 along the first direction, and the battery pack assembly 5100 can be detachably installed in the housing 4000 through the battery installation port 4330 .

[0216] Specifically, the housing 4000 includes a housing base 4100 and a housing top cover 4200 that are fixedly connected. The housing top cover 4200 is fixed to the end of the housing base 4100 that faces away from the surface to be cleaned along the second direction. A battery installation port 4330 is formed between the ends of the housing base 4100 and the housing top cover 4200 that face away from the dust cup structure 1000 along the first direction. The battery pack assembly 5100 can be installed and removed through the battery installation port 4330, facilitating maintenance, replacement, and charging.

[0217] See Figures 1 to 3 and Figure 19 In one embodiment, the handle assembly 6000 includes a handle body 6100 and a handle cover 6200. The handle body 6100 is connected to the housing 4000, and the handle cover 6200 is connected to the end of the handle body 6100 facing away from the housing 4000. A display notch 6220 is provided on the handle cover 6200, and a display area 9000 for displaying target parameters such as dust concentration is located in the display notch 6220.

[0218] See Figures 1 to 3 and Figure 19 Furthermore, the handle assembly 6000 includes a display 6300, which is mounted between the handle body 6100 and the handle cover 6200 and is exposed through a display notch 6220. Specifically, the handle body 6100 is fixedly connected to the top of the housing cover 4200, and the handle cover 6200 is connected to the top of the handle body 6100. A hollow cavity is constructed between the handle cover 6200 and the handle body 6100 for mounting the display 6300. The top of the display 6300 is exposed through the display notch 6220 to form a display area 9000.

[0219] See Figure 40 、 Figure 41 as well as Figure 47As shown, the cordless vacuum cleaner provided in one embodiment of the present application includes a body 10, the body 10 includes a casing 4000, and a battery pack assembly and a negative pressure motor assembly 200 are arranged in the casing 4000; the battery pack assembly 5100 is located on the side of the negative pressure motor assembly 200 away from the surface to be cleaned along the second direction; the negative pressure motor assembly 200 includes a negative pressure motor 3000 and a motor cover structure 2000 for installing the negative pressure motor 3000, and the motor cover structure 2000 is provided with a first exhaust port 2170. The motor cover structure 2000 is provided with at least two second air outlet channels 2310, with a third air outlet channel 2110 disposed between the at least two second air outlet channels 2310. The fluid in the third air outlet channel 2110 and the second air outlet channel 2310 flows in opposite directions. It can be understood that the second air outlet channels 2310 and the third air outlet channel 2110 are used to exhaust air from the negative pressure motor 3000. The second air outlet channels 2310 and the third air outlet channel 2110 cooperate to discharge the fluid introduced by the negative pressure motor 3000. This allows the airflow direction to change multiple times and the airflow path to be longer, 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, significantly reducing the noise level of the negative pressure motor 3000. Furthermore, the multi-section design of the cordless vacuum cleaner significantly improves the space utilization of the cordless vacuum cleaner.

[0220] like Figures 40 to 41 As shown, 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 2400 arranged in sequence along the axial direction of the negative pressure motor 3000; Figure 42 As shown, the motor cover 2200 is provided with a second air outlet 2210 for communicating with the air outlet of the negative pressure motor 3000; Figure 42 and Figure 40 As shown, the motor rear cover 2300 is connected to the motor middle cover 2200, and the two cooperate to enclose a second air outlet channel 2310 connected to the second air outlet 2210; Figure 44 As shown, the motor front cover 2100 is connected to the motor middle cover 2200 at a side away from the motor rear cover 2300, and the motor front cover 2100 is provided with a third air outlet channel 2110 connected to the second air outlet channel 2310. Figure 45As shown, the rear cover 2400 is docked with 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, which connects the third air outlet channel 2110 and the first air outlet 2170. The fluid in the fourth air outlet channel 2410 and the third air outlet channel 2110 flows in opposite directions; 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. Figure 40 As shown, taking the case where two second air outlet channels 2310 are provided and distributed along the radial direction of the negative pressure motor 3000 as an example, the two second air outlet channels 2310 are respectively provided on the left and right sides 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 a direction from top to bottom until it enters the third air outlet channel 2110; for example, Figure 44 From the perspective of FIG, 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 it enters the fourth air outlet channel 2410; 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.

[0221] In the above-mentioned 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 exhaust port 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. Taking the motor front cover 2100, the motor middle cover 2200, the motor rear cover 2300 and the rear cover cover 2400 as an example, which are arranged from left to right in sequence, the fluid flowing out of the motor middle cover 2200 first flows to the left into the motor rear cover 2300 and flows in the motor rear cover 2300, and then the fluid flows to the left to the motor front cover 2100 and flows in the motor front cover 2100, and then flows to the right to the rear cover cover 2400 and flows in the rear cover cover 2400, and the airflow in adjacent air outlet channels flows in opposite directions, that is, the airflow not only circles around the circumference of the motor cover structure 2000 multiple times, but also circles around the axial direction of the motor cover structure 2000. The airflow direction changes multiple times, and the airflow path is longer, so the discharged airflow velocity is low, reducing noise, and 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 split into multiple sections, which greatly improves space utilization.

[0222] like Figure 43 and Figure 44 As shown, in one embodiment, the third air outlet channel 2110 and the fourth air outlet channel 2410 are both arranged around the axial direction of the negative pressure motor 3000. By surrounding the axial direction of the negative pressure motor 3000 with the air outlet channels, the air flow path is extended, so the exhaust air velocity is low, reducing noise. In addition, the 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.

[0223] like Figure 42 As shown, in one embodiment, the motor middle cover 2200 includes a middle cover inner wall 2201 and a middle cover outer wall 2202 surrounding the outside of the middle cover inner wall 2201, and a middle cover partition 2203 is arranged between the middle cover inner wall 2201 and the middle cover outer wall 2202. The middle cover partition 2203 divides the cavity formed by the middle cover inner wall 2201 and the middle cover outer wall 2202 into at least two air outlet channels, and the fluid flow directions of the two adjacent air outlet channels are different. The air outlet channels in the motor middle cover 2200 are split into multiple sections by the middle cover partition 2203, which greatly improves the space utilization.

[0224] See Figures 41 to 44 As shown, in one embodiment, the motor front cover 2100, the motor middle cover 2200, and the 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. The front cover mounting cavity 2120, the middle cover mounting cavity 2260, and the rear cover mounting cavity 2340 together constitute the motor mounting cavity. The second air outlet 2210 is provided on the cavity wall of the middle cover mounting cavity 2260. The second air outlet 2210 can be located within the range of one-half to one-third of the axial length of the negative pressure motor 3000 to ensure that the airflow from the air outlet of the negative pressure motor 3000 can be quickly discharged to prevent the negative pressure motor 3000 from overheating.

[0225] See Figures 40 to 42 As shown, a second air outlet channel 2310 is formed between the outer wall of the motor rear cover 2300 and the wall of the rear cover mounting cavity 2340. In one embodiment, two second air outlet channels 2310 are arranged at intervals along the circumference of 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-shaped pattern. The provision of multiple second air outlet channels 2310 can increase the airflow space, extend the airflow path, and reduce fluid resistance.

[0226] See Figures 40 to 42As shown, in one embodiment, there are two second air outlets 2210, each corresponding to a second air outlet channel 2310; the centerline of each second air outlet 2210 intersects the axis of the negative pressure motor 3000; the angle between the centerlines of the two second air outlets 2210 is 30 to 90 degrees, and further, the angle between the centerlines of the two second air outlets 2210 can be 67 degrees. The dispersed arrangement of the second air outlets 2210 facilitates heat dissipation within the air outlet channel and effectively utilizes the internal space of the motor cover structure 2000, ensuring that the airflow can be divided into two streams.

[0227] See Figure 40 As shown, in one embodiment, the motor rear cover 2300 is provided with a first rear cover cavity 2311 and a second rear cover cavity 2312 that are connected to each other, and the first rear cover cavity 2311 and the second rear cover cavity 2312 form a second air outlet channel 2310; 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 connects the second air outlet 2210 with the first rear cover cavity 2311; the second middle cover cavity 2230 connects the second air outlet channel 2310 with the third air outlet channel. In this way, airflow is achieved within the motor middle cover 2200, the motor rear cover 2300, and the rear cover 2400, and an air outlet channel with a guiding airflow direction is formed, allowing airflow to flow not only circumferentially along the negative pressure motor 3000, but also to move axially along the negative pressure motor 3000.

[0228] See Figure 40 As shown, in one embodiment, a first barrier rib 2313 is provided between the first middle cover cavity 2220 and the first rear cover cavity 2311. The first barrier rib 2313 is used to guide the fluid in the first middle cover cavity 2220 to flow into the first rear cover cavity 2311. The first barrier rib 2313 can prevent the airflow from the second air outlet 2210 from directly entering the second rear cover cavity 2312, thereby preventing the airflow from short-circuiting and causing noise.

[0229] See Figures 42 to 40 As shown, in one embodiment, 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, which connect the third air outlet channel 2410 with the third rear cover cavity 2320. In this way, the rear cover 2400 and the motor front cover 2100 are connected, so that the air flow moves from the rear cover 2400 along the axial direction of the negative pressure motor 3000 to the motor front cover 2100, and the air duct can be extended.

[0230] See 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 both sides of the radial direction of the negative pressure motor 3000. In this way, the flow path of the airflow in the motor cover structure 2000 is extended, fluid loss is reduced, and noise is reduced. Among them, a first front cover cavity 2180 is opened in the motor front cover 2100 and communicates with the first air outlet 2170; see Figures 41 to 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. The fourth rear cover cavity 2330 and the fourth middle cover cavity 2250 connect the fourth air outlet channel 2410 with the first front cover cavity 2180 to converge the fluids of the two third air outlet channels 2110 and introduce the fluids into the fourth air outlet channel 2410, so that the airflow in the rear 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 exhaust port 2170.

[0231] See Figures 41 to 40As shown, in one embodiment, the third middle chamber 2240 and the third rear chamber 2320 are arranged axially along the negative pressure motor 3000, and the fluids within the third middle chamber 2240 and the fourth middle chamber 2250 flow in opposite directions. The third middle chamber 2240 and the third rear chamber 2320 have substantially identical shapes, allowing for smoother fluid flow and reducing fluid loss caused by abrupt wall expansion. Furthermore, the first front chamber 2180, the fourth middle chamber 2250, and the fourth rear chamber 2330 are arranged axially along the negative pressure motor 3000, and have substantially identical shapes, thereby reducing flow velocity loss caused by fluid flowing through uneven walls. The third middle chamber 2240 and the fourth middle chamber 2250 are located on either side of the negative pressure motor 3000 in the radial direction, thereby extending the airflow path. 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 circumferentially along the negative pressure motor 3000, and upwardly enters the second middle cover cavity 2230 of the motor middle cover 2200; then upwardly enters the third air outlet channel in the motor front cover 2100, and the two air flows flowing out through the two second air outlets 2210 are mixed in the third air outlet channel of the motor front cover 2100; and then to The air then flows downward, passing 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 2400. It then flows upward along the fourth rear cover cavity 2330 of the motor rear cover 2300 and the fourth middle cover cavity 2250 of the motor middle cover 2200, reaching the first front cover cavity 2180 of the motor front cover 2100, and then exits the motor cover structure 2000 through the first exhaust port 2170. Specifically, the air can be filtered by the air outlet HEPA provided in the cordless vacuum cleaner before being discharged outside the vacuum cleaner body 10. The airflow not only circles around the circumference of the motor cover structure 2000 multiple times, but also circles around the axial direction of the motor cover structure 2000. The airflow direction changes multiple times, and the airflow path is longer. Therefore, the exhaust airflow velocity is low, reducing noise. In addition, 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. In addition, the motor cover structure 2000 is split into multiple sections, which greatly improves space utilization.

[0232] See Figure 40As shown, in one embodiment, the motor front cover 2100 is provided with a front cover sealing groove 2130, and the front cover sealing groove 2130 is used to install the 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 pressed and matched with the cavity wall of the installation cavity of the body 10. The installation cavity of the body 10 is the installation cavity for installing 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 inhaled by the cordless vacuum cleaner can enter the dust cup structure, and after being filtered and separated by the dust cup structure, enter the air inlet of the negative pressure motor 3000 through the first air outlet of the dust cup structure to ensure the sealing effect, and then flow to the second air outlet 2210 through the air outlet of the negative pressure motor 3000.

[0233] See Figure 40 As shown, a front cover shock absorber 2150 is provided in the front cover 2100 of the motor. The front cover shock absorber 2150 can be made of soft rubber material to reduce the axial vibration of the negative pressure motor 3000 and thus reduce noise. Furthermore, a rear cover shock absorber 2350 made of soft rubber material can also be provided in the rear cover 2300 of the motor to reduce axial vibration and noise. Among them, the rear cover shock absorber 2350 can be bowl-shaped to wrap around the end of the negative pressure motor so that it can reduce axial vibration while also reducing circumferential vibration. More specifically, the front cover shock absorber 2150 and the rear cover shock absorber 2350 do not completely overlap in the axial direction of the negative pressure motor 3000, thereby ensuring the air outlet performance of the negative pressure motor 3000 and meeting its heat dissipation requirements.

[0234] See Figure 40 As shown, in one embodiment, the motor rear cover 2300 and the rear cover 2400 are respectively provided with a rear cover wire hole 2371 and a cover wire hole 2431. The wires of the negative pressure motor 3000 pass through the rear cover wire hole 2371 and the cover wire hole 2431 and are connected to the circuit board. Furthermore, the rear cover wire hole 2371 and the cover wire hole 2431 are respectively connected to the rear cover wire plug 2372 and the cover wire plug 2432, which respectively seal the air outlet channel.

[0235] See Figure 41 and Figure 44 As shown, in one embodiment, 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 slot 2271 for engaging with the front cover buckle 2160. 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 slot 2361 for engaging with the middle cover buckle 2272. Figure 40 and Figure 45 As shown, one of the motor rear cover 2300 and the rear cover 2400 is provided with a rear cover buckle 2362, and the other is provided with a cover slot 2421 for engaging with the rear cover buckle 2362. The combination of the buckle and the slot makes the assembly of the motor cover structure 2000 simpler and saves more space than the screw connection method. Furthermore, the joint between the two adjacent cover bodies (the motor front cover 2100, the motor middle cover 2200, and the motor rear cover 2300 are collectively referred to as the cover bodies) is respectively provided with a notch and a rib. Through the engagement of the notch and the rib, a seal is achieved between the two adjacent cover bodies.

[0236] See Figure 47 As shown, in one embodiment, the body 10 is provided with a suction port assembly connected to the air inlet of the negative pressure motor 3000. After the airflow enters the motor cover structure 2000, it not only circles around the motor cover structure 2000 multiple times along the circumference, but also circles around the motor cover structure 2000 along the axial direction. The airflow direction changes multiple times, and the airflow path is longer. Therefore, the exhaust airflow velocity is low, reducing noise. In addition, the 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. In addition, the motor cover structure 2000 is split into multiple sections, which greatly improves the space utilization of the motor cover structure 2000.

[0237] See 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 nozzle assembly are spaced radially apart from each other along the negative pressure motor 3000. Specifically, the central axis Z2 of the suction nozzle assembly is also the centerline of the body 10. The central axis Z1 of the negative pressure motor 3000 is closer to the air outlet of the negative pressure motor 3000 than the central axis Z2 of the suction nozzle 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 nozzle assembly is 7 mm. In this way, the second air outlet channel 2310 has a larger air flow area, which can reduce fluid loss and reduce noise. At the same time, the negative pressure motor 3000 is roughly coaxial with the first air outlet of the dust cup structure, making the air duct smoother and facilitating the airflow within the dust cup structure to enter the negative pressure motor 3000. 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 brushed DC negative pressure motor 3000. In some other embodiments, when the negative pressure motor 3000 is matched with an AC power supply, the negative pressure motor 3000 may also be an AC motor.
