Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to horizontal cleaning equipment. Background Technology

[0002] With the continuous development of 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 separate body, flexible tube, grip assembly, and floor brush assembly is a common type. When using this type of equipment, the user can move the grip assembly to move the body via the flexible tube connecting the grip assembly and the body, allowing the body to move synchronously via rollers at its bottom. These devices typically have a dedicated display area for showing target parameters such as remaining battery power. However, in related technologies, the conventional method of setting up the display area is to place it on the grip assembly. This method not only easily creates blind spots, making it difficult to observe in a timely manner, but also requires wires to be installed inside the flexible tube between the grip assembly and the body to achieve electrical connection between the display area and the body, resulting in higher manufacturing costs. Summary of the Invention

[0003] Therefore, it is necessary to provide a horizontal cleaning device in which the display area is positioned to minimize blind spots, allowing users to observe it promptly and understand the current operating status of the device, while also reducing manufacturing costs.

[0004] A horizontal cleaning device, the horizontal cleaning device comprising:

[0005] The cleaning module includes a grip assembly, a floor brush assembly, and a flexible tube. One end of the grip assembly is connected to the floor brush assembly, and the other end is connected to the flexible tube.

[0006] The body includes a handle assembly, one end of the flexible tube opposite to the grip assembly is connected to the body, and the end of the body near the surface to be cleaned along a second direction has a roller. The grip assembly is configured to be operablely movable on the surface to be cleaned so as to drive the body to move on the surface to be cleaned via the roller through the flexible tube.

[0007] The handle assembly is provided with a display area for displaying target parameters. The distance between the display area and the surface to be cleaned along the second direction is greater than the distance between other areas of the body and the surface to be cleaned along the second direction, wherein the second direction is the height direction of the body.

[0008] In some embodiments, the body includes a housing, and the handle assembly protrudes from one end of the housing away from the surface to be cleaned along the second direction.

[0009] In some embodiments, the end face of the handle assembly facing away from the surface to be cleaned along the second direction is the top surface of the handle, the top surface of the handle is a convex arc shape, and the display area is located at the center of the top surface of the handle.

[0010] In some embodiments, the handle assembly includes a handle body and a handle cover. The handle body is connected to the housing, and the handle cover is connected to one end of the handle body away from the housing along the second direction. The handle cover has a display notch, and the display area is located at the display notch.

[0011] In some embodiments, the handle assembly includes a display mounted between the handle body and the handle cover, and exposed through the display notch.

[0012] In some embodiments, the display area is used to display dust concentration.

[0013] In some embodiments, the display area 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 grows longer and the second display segment shortens.

[0014] In some embodiments, the body has a suction port assembly, the flexible tube is connected to the suction port assembly, and the suction port assembly includes a dust concentration detection element for detecting the dust concentration of the fluid flowing through the flexible tube.

[0015] In some embodiments, the body includes a circuit board and a negative pressure motor for providing suction force to the floor brush assembly. The negative pressure motor and the dust concentration detection device are both electrically connected to the circuit board, and the circuit board can adjust the suction power of the negative pressure motor based on the measured dust concentration.

[0016] In some embodiments, when the dust concentration is greater than a first dust concentration threshold, the circuit board controls the negative pressure motor to increase the suction power; when the dust concentration is less than a second dust concentration threshold, the circuit board controls the negative pressure motor to decrease the suction power.

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

[0018] In some embodiments, the flexible tube has a connector at one end away from the gripping assembly, the suction port assembly includes a sleeve, the connector and the sleeve are inserted into each other, and the dust concentration detection element includes an infrared emitting part and an infrared receiving part installed on the sleeve, the infrared emitting part and the infrared receiving part being disposed at both radial ends of the sleeve.

[0019] In some embodiments, the connector is inserted into the sleeve, the infrared emitting part and the infrared receiving part are both installed outside the sleeve, and the sleeve is transparent.

[0020] In some embodiments, the inner wall of the sleeve is provided with two mating bosses located at its radial ends, and the end of the mating joint is provided with two mating notches located at its radial ends. Each mating boss is engaged with the corresponding mating notch, and the positions of the infrared emitting part and the infrared receiving part correspond to the two mating bosses respectively.

[0021] In some embodiments, the end of the flexible tube opposite to the gripping assembly has a connector. Of the connector and the suction port assembly, one has a flexible tube locking cavity, and the other has a flexible tube lock that elastically engages with the flexible tube locking cavity, and a flexible tube button connected to the flexible tube lock. The flexible tube button is configured to be pressable to disengage the flexible tube lock from the flexible tube locking cavity.

[0022] In some embodiments, the floor brush assembly 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 is used to display the current of the floor brush motor.

[0023] In some embodiments, the body includes a circuit board and a negative pressure motor for providing suction force to the floor brush. Both the negative pressure motor and the floor brush motor are electrically connected to the circuit board, and the circuit board can adjust the suction power of the negative pressure motor based on the current of the floor brush motor.

[0024] In some embodiments, when the current of the floor brush motor is greater than a first current threshold, the circuit board controls the negative pressure motor to reduce the suction power until the current of the floor brush motor is not greater than the first current threshold.

[0025] When the current of the floor brush motor is less than the second current threshold, the circuit board controls the negative pressure motor to increase the suction power until the current of the floor brush motor is not less than the second current threshold.

[0026] In some embodiments, the circuit board controls the negative pressure motor to increase / decrease the suction power by a preset ratio.

[0027] In some embodiments, the floor brush assembly includes a floor brush, and the display area has a floor brush blockage indicator for identifying that the floor brush is blocked.

[0028] In some embodiments, the body includes a filter structure, and the display area has a filter structure blockage indicator for indicating that the filter structure is blocked.

[0029] In some embodiments, the body includes:

[0030] chassis;

[0031] The filter structure is installed in the housing; and

[0032] The negative pressure motor assembly, the power supply assembly, and the handle assembly are all installed on the housing and are all located on one side of the filter structure along the first direction. The negative pressure motor assembly has a negative pressure motor air inlet at the end of the filter structure along the first direction.

[0033] The power supply component is located on the side of the negative pressure motor assembly facing away from the surface to be cleaned along the second direction, and the handle assembly is located on the side of the power supply component facing away from the negative pressure motor assembly along the second direction, wherein the first direction is the axial direction of the negative pressure motor in the negative pressure motor assembly, and the first direction is perpendicular to the second direction.

[0034] In the aforementioned horizontal cleaning device, the display area is located within the handle assembly of the machine body. During use, the machine body is typically placed on the surface to be cleaned, and its overall height is lower than the cleaning module, allowing the user to easily observe it by simply looking down. Furthermore, 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 machine body and the surface. This means the display area is located at its maximum distance from the surface and at its maximum height within the machine body. This design prevents the display area from being obstructed by other structures within the machine body, thus minimizing blind spots. Users can easily observe the display area from any angle after looking down, allowing them to promptly understand the current operating status of the equipment. Moreover, since the display area is located within the machine body rather than the handle assembly, there is no need for the wiring for electrical connection between the display area and the machine body within a flexible tube, as is required in existing technologies, reducing manufacturing costs.

[0094] 9000, Display Area. Detailed Implementation

[0095] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0096] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0097] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0098] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0099] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0100] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, 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 possible implementation.

[0101] See Figures 1 to 3 An embodiment of this application provides a body 10 for a horizontal cleaning device. The horizontal cleaning device includes a grip assembly 8100, a floor brush assembly 8200, and a flexible tube 8300. One end of the grip 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 grip assembly 8100 is connected to the body 10. The body 10 has a roller at the end near the surface to be cleaned along a second direction. In the working state, the grip assembly 8100 is configured to be operably movable on the surface to be cleaned, so that the flexible tube 8300 drives the body 10 to move on the surface to be cleaned via the roller.

[0102] One embodiment of this application provides a body 10 including 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 mounted on the housing 4000. The negative pressure motor assembly 200, the power supply assembly, and the handle assembly 6000 are all located on one side of the filter structure 100 along a first direction. The negative pressure motor assembly 200 has a negative pressure motor air inlet 3100 at its end along the first direction near the filter structure 100. The power supply assembly is located on the side of the negative pressure motor assembly 200 opposite to the surface to be cleaned along a second direction, and the handle assembly 6000 is located on the side of the power supply assembly opposite to the negative pressure motor assembly 200 along the second direction. The first direction is the axial direction of the negative pressure motor 3000 in the negative pressure motor assembly 200, and the second direction is the height direction of the body 10. 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 the 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 the end along the first direction near the filter structure 100, the airflow exiting 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 into the negative pressure motor 3000 from the negative pressure motor air inlet 3100 roughly along the first direction. It can be seen that after the airflow exits the filter structure 100, it can directly flow into the negative pressure motor 3000 without undergoing a large angle of turn, thus reducing wind resistance, making the airflow process smoother, and reducing fluid loss. Furthermore, the second direction is the height direction of the body 10, and the first direction is perpendicular to the second direction; that is, in the operating state, the first direction is horizontal. 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, on the horizontal side of the filter structure 100. 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. In other words, in use, the power supply assembly is above the negative pressure motor assembly 200, and the handle assembly 6000 is above the power supply assembly. The axis 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. With the power supply assembly above the negative pressure motor assembly 200 and the handle assembly 6000 above the power supply assembly, the space saved in the second direction after the negative pressure motor 3000 is "laid down" can be better utilized, making the structural distribution 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 within the body 10, placing it below the handle assembly 6000 allows most of the weight of the body 10 to be concentrated below the handle assembly 6000, making it easier for the user to lift the handle assembly 6000.

[0104] Figures 1 to 3 From a visual perspective, the second direction is up and down, the first direction is left and right, and the third direction is front and back. When a horizontal cleaning device is in use, the second direction is up and down.

[0105] See Figures 3 to 6 In some embodiments, the handle assembly 6000 and the power supply assembly overlap at least partially along a third direction, and the dimension of the handle assembly 6000 along the third direction is larger than the dimension of the power supply assembly along the third direction. This configuration makes it easier for users to move or store the horizontal cleaning device over long distances by lifting the handle assembly 6000.

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

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

[0108] In some embodiments, the portion of the battery pack assembly 5100 exposed at the battery mounting port 4330 is provided with a charging port. Because the charging port is exposed at the battery mounting port 4330, it allows users to conveniently charge the battery pack assembly 5100 via 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 subsequent embodiments, the power supply component shown in the accompanying drawings, specifically the battery pack assembly 5100, will be used as an example for further explanation.

[0110] See Figures 4 to 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 inserted into the housing 4000 through the battery mounting port 4330, and its outer end does not protrude from the end face of the housing 4000. This arrangement can protect the battery pack assembly 5100 from collision damage through the outer end of the housing 4000, and at the same time reduce 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 inside the housing 4000 and connected thereto. The battery pack assembly 5100 is detachably installed in the battery compartment 5200 through the battery mounting port 4330, and the battery pack assembly 5100 and the battery compartment 5200 slide together in a first direction.

[0112] Specifically, the battery compartment 5200 is fixedly installed inside the housing 4000, and the end of the battery compartment 5200 facing away from the filter structure 100 along the first direction has a battery compartment opening 5240 connected to the battery mounting port 4330. The battery compartment opening 5240 is used for the battery pack assembly 5100 to enter and exit. The battery pack assembly 5100 is detachably installed in the battery compartment 5200 through the battery mounting port 4330 and the battery compartment opening 5240 in sequence. When the battery pack assembly 5100 is installed in the battery compartment 5200 without being locked in position, it slides with the battery compartment 5200 along the first direction. In this way, the installation and removal of the battery pack assembly 5100 can be completed simply by pushing it in or pulling it out, making the 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 configured with a compartment groove 5210 extending in a first direction, and the battery pack assembly 5100 has a sliding plate 5110 extending in the first direction, the sliding plate 5110 being slidably mounted in the compartment groove 5210.

[0114] Specifically, the inner wall of the battery compartment 5200 has two ribs 5211 extending along a first direction and spaced apart, forming a compartment groove 5210 between the two ribs 5211. The battery pack assembly 5100 has a battery pack shell 5140 that surrounds the battery pack 5150, and a sliding plate 5110 protrudes from the outer wall of the battery pack shell 5140. When the battery pack assembly 5100 is pushed or pulled, the sliding plate 5110 slides along the first direction within the compartment groove 5210 to guide and limit movement, making the assembly and disassembly process of the battery pack assembly 5100 smoother.

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

[0116] See Figures 7 to 9 ,as well as Figure 11 In some embodiments, of the battery compartment 5200 and the battery pack assembly 5100, one is provided with a battery pack locking slot 5220, and the other is provided with a battery pack locking block 5120 that elastically engages with 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 out of the battery pack locking slot 5220.

[0117] In the embodiment shown in the attached drawings, the battery compartment 5200 is provided with a battery pack locking groove 5220, and the battery pack assembly 5100 is provided with a battery pack locking block 5120 that elastically engages with the battery pack locking groove 5220, and a battery pack release button 5130 connected to the battery pack locking block 5120. Specifically, the battery pack locking groove 5220 is formed in the wall of the battery compartment 5200, the battery pack locking block 5120 and the battery pack release button 5130 are integrally formed or fixedly connected, and the battery pack release button 5130 and the battery pack shell 5140 are elastically connected by a battery pack locking elastic member 5160. The battery pack locking elastic member 5160 is used to apply an elastic force to the battery pack locking block 5120 through the battery pack release button 5130, so that the battery pack locking block 5120 engages with the battery pack locking groove 5220. When the battery pack release button 5130 is pressed, it causes the battery pack locking block 5120 to overcome the elastic force of the battery pack locking elastic element 5160 and disengage from the battery pack locking slot 5220. Through this locking structure, the battery pack assembly 5100 can be securely and stably locked within the battery compartment 5200, thereby achieving stable power supply. Simultaneously, it allows for quick disassembly and assembly when the battery pack assembly 5100 needs to be removed, making operation more convenient and efficient.

[0118] See Figure 7 , Figure 8 , Figure 10 and Figure 11 In some embodiments, the body 10 includes a circuit board 5300 mounted inside the housing 4000. The circuit board 5300 includes a board body 5310 and a coupler 5320 connected to each other. The board body 5310 is located outside the battery compartment 5200, and the coupler 5320 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 has its body 5310 fixedly mounted on the outer wall of the battery compartment 5200, and the coupler 5320 protrudes from the body 5310. The battery compartment 5200 has a through-hole 5230 for the coupler, and the coupler 5320 extends into the interior of the battery compartment 5200 through the through-hole 5230 and makes contact with 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 outside the coupler 5320, the flexible coupler cap 5330 being inserted into the coupler through hole 5230.

[0121] The flexible coupler cap 5330 is made of flexible material such as silicone or rubber. It is inserted into the coupler through hole 5230 and is interference-fitted with it, thereby protecting the coupler 5320 from collision damage.

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

[0123] Specifically, from the perspective of the attached drawings, the top of the flexible coupler cap 5330 has a protruding brim 5331, which blocks the top end wall of the coupler through hole 5230. Thus, the brim 5331 blocking the end wall of the coupler through hole 5230 prevents the flexible coupler cap 5330 from falling downwards. Furthermore, it provides a good sealing effect at the coupler through hole 5230, preventing dust from reaching the surface of the circuit board 5300 and causing damage when the battery pack assembly 5100 is not installed.

[0124] See Figure 3 , Figure 7 and Figure 11 In some embodiments, the size of the battery compartment 5240 gradually increases in the direction along the first direction and away from the filter structure 100. This arrangement allows for a larger inlet size of the battery compartment 5240, thereby facilitating the user's installation and removal of the battery pack assembly 5100 from this location.

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

[0126] Specifically, in Figure 7 From this perspective, the bottom wall of the battery compartment 5200 slopes downwards. Users can press the battery pack release button 5130 with their thumb while simultaneously using their other four fingers to lift the battery pack assembly 5100 from the bottom for disassembly and assembly; this can be easily accomplished with one hand, making the operation quite convenient. Except for the bottom wall, no other area of ​​the battery compartment 5200 is designed to extend at an angle, thus minimizing the size of the battery compartment 5200 and reducing the space it occupies within the housing 4000. Of course, in other embodiments, the battery compartment opening 5240 can also be designed as a flared shape, smaller on the inside and larger on the outside.

[0127] See Figure 3 , Figure 4 and Figure 6In some embodiments, the housing 4000 includes a grid plate 4110 that divides the inner cavity of the housing 4000 into a first mounting cavity 4310 and a second mounting cavity 4320 arranged along a first direction. The grid plate 4110 has an air passage 4111 that connects the first mounting cavity 4310 and the second mounting cavity 4320. The filter structure 100 is installed in the first mounting cavity 4310, and the negative pressure motor assembly 200 and the power supply assembly (battery pack assembly 5100) are installed in the second mounting cavity 4320.

[0128] Specifically, the housing base 4100 includes a grid plate 4110, which is perforated to create an air passage 4111. By setting the grid plate 4110, the airflow can be guided and concentrated, so that the airflow discharged from the filter structure 100 to the first mounting cavity 4310 passes more concentratedly through the air passage 4111 into the second mounting cavity 4320, thereby flowing more concentratedly into the negative pressure motor assembly 200, reducing fluid loss and improving suction efficiency.

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

[0130] Specifically, the negative pressure motor assembly 200 includes a motor housing structure 2000 and a negative pressure motor 300 installed within the motor housing structure 2000. The specific structure of the motor housing structure 2000 will be described in subsequent embodiments. The negative pressure motor 300 provides suction force, drawing external airflow carrying waste into the housing 4000 through the first suction port 4340. The waste then enters the filter structure 100 through the first ash inlet 1111 for filtration and separation. The waste is retained in the filter structure 100, while the clean airflow exits through the first air outlet 1113 to the first mounting cavity 4310. It is then drawn into the second mounting cavity 4320 through the air passage 4111, and into the motor's interior through the negative pressure motor inlet 3100. After exiting the negative pressure motor 3000, the airflow is discharged to the external environment through the first outlet 4350 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 focus on the filter structure 100 shown in the accompanying drawings as a dust cup structure 1000. The specific internal structure of 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 at one end along a third direction, which communicates with the second mounting cavity 4320 and is used for discharging fluid. A second HEPA filter 5410 and an aromatherapy component 5420 are installed at the first outlet 4350, wherein the third direction is perpendicular to the first and second directions.

[0133] Specifically, the first outlet 4350 is positioned directly opposite the air outlet of the negative pressure motor assembly 200 to facilitate smooth airflow. In the above embodiment, by installing a second HEPA filter 5410 at the first outlet 4350, the airflow can be filtered again before flowing into the external environment, further reducing the probability of dust discharge. By installing an 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 provided at both ends of the housing 4000 along a third direction, with a second HEPA filter 5410 and an aromatherapy component 5420 installed at each of the two first outlets 4350.

[0134] See Figure 2 , Figure 6 and Figure 12 In some embodiments, the first mounting 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 mounting cavity 4310, and the outer wall of the filter structure 100 away from the surface to be cleaned along the second direction forms part of the outer wall of the body 10.

[0135] From the perspective of the attached drawings, the top of the first mounting cavity 4310 is open. After the filter structure 100 is installed in the first mounting cavity 4310, the opening at the top of the first mounting cavity 4310 is closed. The shape of the top of the filter structure 100 is designed to match the outer wall of the body 10, that is, to match the top cover 4200 of the housing, so that it forms part of the outer wall of the body 10 after installation. This eliminates the need for a separate shell structure at this location, simplifying the structure. In the embodiment shown in the attached drawings, the top wall of the filter structure 100 is set as a quarter-spherical shape to match the shape of the top cover 4200 of the housing.

[0136] See Figure 4 , Figure 12 , Figure 28 and Figure 31In some embodiments, one of the cavity wall of the first mounting 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, with the bottom cover positioning protrusion 4311 inserted into the bottom cover positioning groove 1520.

[0137] In the embodiment shown in the attached drawings, the bottom wall of the first mounting cavity 4310 is provided with a bottom cover positioning protrusion 4311, and the bottom end of the filter structure 100 (dust cup structure 1000) is provided with a bottom cover positioning groove 1520. 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 for positioning, facilitating 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, multiple sets of matching bottom cover positioning protrusions 4311 and bottom cover positioning grooves 1520 are provided to further optimize the limiting effect and restrict the rotation and movement of the filter structure 100 (dust cup structure 1000) in the horizontal plane after it is installed in the first mounting cavity 4310.

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

[0140] In the embodiment shown in the attached drawings, the cavity wall of the first mounting cavity 4310 is recessed with a cup-making positioning groove 4312, and the filter structure 100 (dust cup structure 1000) is protruding with a cup-making hook 1131. The cup-making hook 1131 is attached to the cup-making positioning groove 4312, which restricts the movement of the filter structure 100 (dust cup structure 1000) in the horizontal plane after it is installed in the first mounting cavity 4310, thereby enhancing the limiting effect. In other embodiments, the positions of the cup-making hook 1131 and the cup-making 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 disposed at one end of the filter structure 100 along the second direction near the surface to be cleaned, and the cup holder hook 1131 is disposed at one end of the filter structure 100 along the first direction near the second mounting cavity 4320. In the second direction, the cup holder 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 located at the bottom of the filter structure 100 (dust cup structure 1000), and the cup holder hook 1131 is located on the side of the filter structure 100 (dust cup structure 1000), near the top. This arrangement allows for the positioning of the top and bottom of the filter structure 100 (dust cup structure 1000) through the cooperation of the cup holder hook 1131 and the cup holder positioning groove 4312, as well as the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520. This optimizes the positioning effect and makes the filter structure 100 (dust cup structure 1000) more stable after installation, less prone to shaking or displacement.

[0144] See Figure 4 , Figure 12 and Figure 27 In some embodiments, of the cavity wall of the first mounting cavity 4310 and the filter structure 100, one is provided with a cover snap-fit ​​groove 4313, and the other is provided with a cover protrusion 1410 that elastically snaps into the cover snap-fit ​​groove 4313, and a cover rotating buckle 1420 connected to the cover protrusion 1410. The cover rotating buckle 1420 is configured to be operablely movable to drive the cover protrusion 1410 out of the cover snap-fit ​​groove 4313.

[0145] In the embodiment shown in the attached figure, the cavity sidewall of the first mounting cavity 4310 is recessed with a cover snap-fit ​​groove 4313, the filter structure 100 (dust cup structure 1000) has a cover protrusion 1410 that elastically snaps into the cover snap-fit ​​groove 4313, and a cover rotating buckle 1420 connected to the cover protrusion 1410.

[0146] Specifically, the dust cup structure 1000 includes a dust cup top cover 1400. An elastic element connects the top cover protrusion 1410 and the dust cup top cover 1400. The elastic force of the elastic element allows the top cover protrusion 1410 to elastically engage with the top cover locking groove 4313. A top cover rotating buckle 1420 is rotatably connected to the dust cup top cover 1400. By rotating the top cover rotating buckle 1420, it abuts against the top cover protrusion 1410, which can push the top cover protrusion 1410 out of the top cover locking groove 4313. For example, when a user holds the top cover rotating buckle 1420 and rotates it clockwise, the top cover rotating buckle 1420 will push the top cover protrusion 1410 to move away from the top cover locking groove 4313 until it disengages from the top cover locking groove 4313. Then, the user applies upward force and lifts the dust cup structure 1000 using the dust cup handle 1430, allowing the dust cup structure 1000 to be completely removed from the first mounting cavity 4310. During installation, after the user holds the top cover rotating buckle 1420 and places the dust cup structure 1000 into the first mounting cavity 4310, they release their hand from the top cover rotating buckle 1420. The top cover protrusion 1410 will then engage with the top cover locking groove 4313 under the rebound force of the elastic element, thus completing the locking process.

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

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

[0149] As mentioned earlier, in the working state, the grip assembly 8100 is configured to be operablely movable on the surface to be cleaned, so as to drive the machine body 10 to move on the surface to be cleaned via the flexible tube 8300 and the rollers. However, in the non-working state, when moving the horizontal cleaning device over a long distance, the machine body 10 cannot be moved by moving the grip assembly 8100 alone, 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 machine body 10 with the other hand to move the horizontal cleaning device; or, the grip assembly 8100 can be attached to the mounting slot 4210, and then the horizontal cleaning device can be moved as a whole.

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

[0151] When using this horizontal cleaning device, the machine body 10 is placed on the surface to be cleaned and can move by the rollers at its bottom. The floor brush assembly 8200 is aligned with the area to be cleaned, and the negative pressure motor 2000 in the machine body 10 provides suction. External airflow carrying debris is sucked in from the suction port of the floor brush assembly 8200, passes through the grip assembly 8100 and the flexible tube 8300 in sequence, and then enters the filter structure 100 of the machine body 10 for filtration. After flowing through the negative pressure motor 2000, it is discharged from the machine body 10.

[0152] See Figure 1 In some embodiments, the grip assembly 8100 includes a grip handle 8110 and an extension rod 8120 disposed between the grip handle 8110 and the floor brush assembly 8200, the extension rod 8120 being detachably connected to the floor brush assembly 8200 and / or the grip 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 easily removed from the grip assembly 8100 for maintenance and replacement. Similarly, 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 easily removed from the grip handle 8110 as a whole for maintenance and replacement.

[0154] Preferably, the extension rod 8120 can be configured as a telescopic rod to facilitate adjustment according to the user's needs. (See also...) Figure 1 and Figure 13 In some embodiments, a localization brush 8111 is rotatably connected to the end of the handle 8110 near the extension rod 8120. The localization brush 8111 is small in size and suitable for cleaning small crevices and corners. The horizontal cleaning device can have two cleaning modes; in one mode, the localization brush 8111 is rotated to... Figure 1 Store the extension rod 8120 and floor brush assembly 8200 in the indicated location, attach them to the handle 8110, and use the floor brush assembly 8200 to clean large areas such as the floor or carpet. In another mode, remove the extension rod 8120 and floor brush assembly 8200 from the handle 8110, and rotate the local brush 8111 to... Figure 13As shown, use the spot cleaning brush 8111 to clean smaller crevices and corners. This allows for a wider range of applications for this horizontal cleaning device.

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

[0156] In the embodiment shown in the attached drawings, the first electrical connection part 8121 is a pin, and the handle 8110 is provided with a slot that engages with the first electrical connection part 8121; the second electrical connection part 8122 is a slot, and the floor brush assembly 8200 is provided with a pin that engages with the second electrical connection part 8122. Through the first electrical connection part 8121 and the second electrical connection part 8122, the circuit of the floor brush assembly 8200 can be made conductive after installation.

[0157] See Figures 14 to 15 In some embodiments, of the floor brush assembly 8200 and the extension rod 8120, one is provided with a floor brush locking cavity 8123, and the other is provided with a floor brush lock 8210 that elastically engages with 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 operablely pressed to drive the floor brush lock 8210 out of the floor brush locking cavity 8123.

[0158] In the embodiment shown in the attached drawings, the extension rod 8120 is provided with a floor brush locking cavity 8123, the floor brush assembly 8200 is provided with a floor brush lock 8210 that elastically engages with the floor brush locking cavity 8123, and a floor brush button 8220 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 at least one of them is provided with an elastic element between itself and the housing or other components of the floor brush assembly 8200. The elastic element causes the floor brush lock 8210 to elastically engage with the floor brush locking cavity 8123 through its rebound force. When the floor brush button 8220 is pressed, the rebound force of the elastic element can be overcome, causing the floor brush lock 8210 to disengage from the floor brush locking cavity 8123.

[0159] See Figures 16 to 17 In some embodiments, of the handle 8110 and the extension rod 8120, one is provided with a handle locking cavity 8112, and the other is provided with a handle lock 8124 that is elastically engaged in the handle locking cavity 8112, and a handle button 8125 connected to the handle lock 8124. The handle button 8125 is configured to be operablely pressed to drive the handle lock 8124 out of the handle locking cavity 8112.

[0160] In the embodiment shown in the attached figure, the handle 8110 is provided with a handle locking cavity 8112, the extension rod 8120 is provided with a handle lock 8124 that elastically engages with the handle lock cavity 8112, and a handle button 8125 connected to the handle lock 8124. The specific mating structure is basically the same as that of the floor brush lock 8210, the floor brush button 8220, and the floor brush lock cavity 8123, and will not be described in detail here.

[0161] See Figure 18 In some embodiments, the extension rod 8120 has mutually separated fluid channels 8126 and cable routing channels 8127. Specifically, both the fluid channels 8126 and cable routing channels 8127 extend along the length of the extension rod 8120. The fluid channels 8126 are used for airflow carrying debris, and the cable routing channels 8127 are used for cables. By providing separate fluid channels 8126 and cable routing channels 8127, the cables can be protected from damage caused by debris and airflow.

[0162] See Figure 20 In some embodiments, the flexible tube 8300 has a third electrical connection part 8311 at one end away from the gripping assembly 8100 for connecting and communicating with the body 10. The third electrical connection part 8311 is a pin or a slot.

[0163] In the embodiment shown in the attached drawings, the third electrical connection part 8311 is a pin, and the body 10 is provided with a slot that engages with the first electrical connection part 8121. Through the third electrical connection part 8311, circuitry between the cleaning module 20 and the body 10 can be established.

[0164] See Figures 1 to 2 An embodiment of this application provides a horizontal cleaning device including a body 10 and a cleaning module 20. The cleaning module 20 includes a grip component 8100, a floor brush component 8200, and a flexible tube 8300. One end of the grip component 8100 is connected to the floor brush component 8200, and the other end is connected to the flexible tube 8300. The end of the flexible tube 8300 facing away from the grip component 8100 is connected to the body 10. The body 10 has a display area 9000 for displaying target parameters. The distance between the display area 9000 and the surface to be cleaned along a second direction is greater than the distance between other areas of the body 10 and the surface to be cleaned along the second direction, where the second direction is the height direction of the body 10.

[0165] In the above embodiment, the display area 9000 is disposed on the body 10. During use, the body 10 is typically placed on the surface to be cleaned, and its overall height is lower than that of the cleaning module 20, allowing the user to easily observe it by simply looking down. Furthermore, in the second direction, the distance between the display area 9000 and the surface to be cleaned is greater than the distance between other areas of the body 10 and the surface to be cleaned. That is, the display area 9000 is located at the position with the largest distance from the surface to be cleaned within the body 10, and also at the position with the greatest height on the body 10. This arrangement prevents the display area 9000 from being obstructed by other structures within the body 10, thus minimizing blind spots. Users can easily observe the display area 9000 from any angle after looking down, allowing them to promptly understand the current operating status of the device. In addition, since the display area 9000 is disposed on the body 10 rather than in the grip component 8100, there is no need to install wires within the flexible tube 8300 for electrical connection between the display area 9000 and the body 10, as is required in existing technologies, reducing 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 the end of the housing 4000 facing away from the surface to be cleaned along a second direction, and a display area 9000 is disposed on the handle assembly 6000. That is, in the use state, the handle assembly 6000 protrudes from the top of the housing 4000. By placing the display area 9000 on the handle assembly 6000, which has the largest height in the body 10, the handle assembly 6000, the display area 9000 is positioned high and is not easily obstructed by other structures in the body 10. When the user looks down, the display area 9000 can be easily observed from any angle, thereby allowing the user to understand the current operating status of the device in a timely manner.

[0167] See Figure 1 , Figure 2 and Figure 19 In some embodiments, the end face of the handle assembly 6000 facing away from the surface to be cleaned along the second direction 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 top surface 6210 of the handle protrudes upwards and is arc-shaped, so its center position is the position with the greatest height. Setting the display area 9000 here ensures that the display area 9000 is at a high position. In other embodiments, the top surface 6210 of the handle can also be set to other shapes, as long as the display area 9000 is at its position with the greatest height.

[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, and the handle cover 6200 is connected to one end of the handle body 6100 away from the housing 4000 along a second direction. The handle cover 6200 has a display notch 6220, 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 exposed through a display notch 6220. Specifically, the handle body 6100 is fixedly connected to the top of the housing top cover 4200, and the handle cover 6200 is connected to the top of the handle body 6100. A hollow cavity is formed between the handle cover 6200 and the handle body 6100 for mounting the display 6300. The 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, the display bracket 6400 is fixedly mounted on the handle body 6100, and the top of the display 6300 is also provided with a transparent display window 6500, 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 grows longer and the second display segment shortens.

[0173] For example, the first display segment is red, and the second display segment is blue. As the dust concentration increases, the red portion of the dust concentration display bar increases, and the blue portion decreases; conversely, as the dust concentration decreases, the blue portion of the dust concentration display bar increases, and the red portion decreases. This allows users to quickly and intuitively understand the level of dirt on the surface to be cleaned.

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

[0175] Specifically, the suction assembly 7000 is installed at the first suction port 4340. The airflow and debris delivered from the flexible tube 8300 reach the first suction port 4340 through the suction assembly 7000. 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 degree of dirt on the surface to be cleaned.

[0176] See Figure 3 , Figure 20 and Figure 23 In some embodiments, the body 10 includes a circuit board 5300 and a negative pressure motor 3000 for providing suction force to the floor brush assembly 8200. The negative pressure motor 3000 and a dust concentration detection element 7100 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 measured dust concentration. Specifically, the dust concentration detection element 7100 detects the dust concentration of the fluid flowing through the flexible tube 8300 and feeds it back to the circuit board 5300. The circuit board 5300 controls the display area 9000 to display the current dust concentration. Simultaneously, the circuit board 5300 adjusts the suction power of the negative pressure motor 3000 based on the current dust concentration to match it. For example, when the dust concentration is too high, the suction power of the negative pressure motor 3000 is increased to improve suction strength; conversely, the suction power of the negative pressure motor 3000 is decreased 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 its 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 decrease its suction power. Specifically, the first dust concentration threshold can be a set upper limit value, and the second dust concentration threshold can be a set lower limit value. The first and second dust concentration thresholds can be set by the user or configured uniformly before leaving the factory. When the dust concentration is between the first and second dust concentration thresholds, it is assumed that the current suction power of the negative pressure motor 3000 is sufficient to meet cleaning and energy-saving requirements; when the dust concentration is greater than the first dust concentration threshold, it is assumed that the current suction power of the negative pressure motor 3000 is insufficient, which may lead to incomplete cleaning, so it is necessary to increase the suction power; when the dust concentration is less than the second dust concentration threshold, it is assumed that the current suction power of the negative pressure motor 3000 is excessive, which is not conducive to energy saving, so the suction power can be reduced.

[0178] See 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 before leaving the factory. For example, the suction power is increased / decreased by 20% of the current value. If the dust concentration still does not meet the standard after a single increase / decrease, the suction power is increased / decreased in the above manner. In this way, fine adjustment of the suction power can be achieved.

[0179] See Figure 21 , Figure 22 , Figure 23 and Figure 25 In some embodiments, the flexible tube 8300 has a connector 8310 at the end opposite to the gripping assembly 8100. The suction port assembly 7000 includes a sleeve 7200, with the connector 8310 and the sleeve 7200 interlocking. The dust concentration detection element 7100 includes an infrared emitter 7110 and an infrared receiver 7120 mounted on the sleeve 7200, with the infrared emitter 7110 and infrared receiver 7120 respectively located at both radial ends of the sleeve 7200. Specifically, the suction port assembly 7000 includes a suction port shell 7300, with the sleeve 7200 fixed to the suction port shell 7300. Both the infrared emitter 7110 and the infrared receiver 7120 are infrared connectors, each fixed to both radial ends of the sleeve 7200. The infrared rays emitted by the infrared emitter 7110 pass through the interior of the connector 8310 and are received by the infrared receiver 7120. Depending on the dust concentration inside the connector 8310, the information received by the infrared receiver 7120 will also be different, thereby enabling the current dust concentration value to be determined.

[0180] See Figure 21 , Figure 22 , Figure 23 and Figure 25 In some embodiments, the connector 8310 is inserted into the sleeve 7200, and both the infrared emitter 7110 and the infrared receiver 7120 are mounted outside the sleeve 7200, which is transparent. Specifically, the connector 8310 extends from the opening of the suction 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 emitter 7110 and the infrared receiver 7120 are mounted outside the sleeve 7200, the emission and reception of infrared rays are not affected. In other embodiments, the sleeve 7200 can also be inserted into the connector 8310, thus the transparency of the sleeve 7200 is not critical.

[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 mating bosses 7210 respectively located at both ends of its radial direction, and the end of the connector 8310 is provided with two mating notches 8312 respectively located at both ends of its radial direction. Each mating boss 7210 is engaged with the corresponding mating notch 8312. The positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two mating bosses 7210 respectively.

[0182] Specifically, each mating boss 7210 engages with a corresponding mating notch 8312 to limit the insertion of the mating connector 8310 into the sleeve 7200. The positions of the infrared emitting part 7110 and the infrared receiving part 7120 correspond to the two mating bosses 7210, that is, the infrared emitting part 7110 is located on the outer side of the area where one of the mating bosses 7210 is located on the sleeve 7200, and the infrared receiving part 7120 is located on the outer side of the area where the other mating boss 7210 is located. Since the infrared emitting unit 7110 and the infrared receiving unit 7120 are positioned corresponding to the two mating protrusions 7210, and each mating protrusion 7210 engages with its corresponding mating notch 8312, the infrared rays emitted by the infrared emitting unit 7110 can pass through the corresponding mating protrusion 7210 and enter the mating joint 8310 through the corresponding mating notch 8312. After passing through the mating joint 8310, the infrared rays will pass through the corresponding mating protrusion 7210 through the other mating notch 8312 and be received by the infrared receiving unit 7120. In this way, the emission and reception of infrared rays can be achieved through the cooperation of the two mating protrusions 7210 and the mating notch 8312.

[0183] See Figures 21 to 25 In some embodiments, a suction seal 7400 is provided between the connector 8310 and the sleeve 7200 to enhance the sealing performance. 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 the radial ends of the sealing ring 7410, and each lug 7420 has a sealing groove 7421. When the connector 8310 is inserted into the sleeve 7200 and the mating boss 7210 is engaged with the mating notch 8312, the inner wall of the connector 8310 protrudes inward compared to the inner wall of the mating boss 7210. The seal 7400 can precisely fill the radial dimensional difference between the inner wall of the connector 8310 and the inner wall of the mating boss 7210, allowing airflow to pass through this area more smoothly. The inner side of the mating boss 7210 is provided with a sealing element block 7211, which is inserted into the corresponding sealing element slot 7421 to fix the position of the sealing element 7400.

[0184] See Figure 20 and Figure 25In some embodiments, the end of the flexible tube 8300 away from the gripping assembly 8100 has a connector 8310. Of the connector 8310 and the suction assembly 7000, one is provided with a flexible tube locking cavity 7310, and the other is provided with a flexible tube lock 8313 that elastically engages with 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 operablely pressed to drive the flexible tube lock 8313 out of the flexible tube locking cavity 7310.

[0185] In the embodiment shown in the attached drawings, the suction port housing 7300 of the suction port assembly 7000 is provided with a flexible tube locking cavity 7310, the connector 8310 is provided with a flexible tube lock 8313 that elastically engages with the flexible tube locking cavity 7310, and a flexible tube button 8314 connected to the flexible tube lock 8313. Specifically, the flexible tube button 8314 and the flexible tube lock 8313 are integrally formed or fixedly connected. The flexible tube button 8314 and the housing and other structures of the connector 8310 are connected by an elastic element. The elastic element pushes the flexible tube button 8314 with its rebound force, thereby pushing the flexible tube lock 8313 to elastically engage with the flexible tube locking cavity 7310. When the flexible tube button 8314 is pressed against the elastic force, the flexible tube lock 8313 disengages from the flexible tube locking cavity 7310. In this way, the locking and unlocking of the flexible tube 8300 and the body 10 can be realized.

[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, instead of a floor brush motor, an impeller connected to the floor brush can be installed, with the impeller rotating due to the fluid in the air duct, which in turn drives 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 to the floor brush. Both the negative pressure motor 3000 and the floor brush motor are 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] Understandably, the suction resistance of the floor brush assembly 8200 and the current of the floor brush motor will vary depending on the type or roughness of the surface to be cleaned. For example, the suction resistance of the floor brush assembly 8200 will be greater when cleaning a carpet or sofa, and correspondingly, the current of the floor brush motor will be higher; while the suction resistance of the floor brush assembly 8200 will be lower when cleaning a wooden floor, and correspondingly, the current of the floor brush motor will be lower. Furthermore, for the same type of surface to be cleaned, the greater the roughness, the greater the suction resistance of the floor brush assembly 8200 and the higher the current of the floor brush motor. Understandably, when the current of the floor brush motor fed back to circuit board 5300 is too high, it indicates that the current suction resistance is too high, making it difficult for the user to operate. In this case, the suction power of the negative pressure motor 3000 needs to be appropriately reduced to lower the suction resistance. When the current of the floor brush motor fed back to circuit board 5300 is too low, it indicates that the current suction resistance is too low, and the floor brush assembly 8200 may slip on the surface to be cleaned. In this case, the suction power of the negative pressure motor 3000 needs to be appropriately increased to increase the suction resistance.

[0190] See Figure 1 and Figure 3 In some embodiments, when the current of the floor brush motor exceeds a first current threshold, the circuit board 5300 controls the negative pressure motor 3000 to reduce its 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 its 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 and second current thresholds 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 and second current thresholds, it is assumed that the suction resistance provided by the current suction power of the negative pressure motor 3000 is appropriate, making cleaning easier for users and preventing the floor brush assembly 8200 from slipping. When the current of the floor brush motor is greater than the first current threshold, it is assumed that the current suction power of the negative pressure motor 3000 is too high and needs to be reduced. When the current of the floor brush motor is less than the second current threshold, it is assumed that the current suction power of the negative pressure motor 3000 is too low and 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 before leaving the factory. For example, the suction power is increased / decreased by 20% of the current value. If the current of the floor brush motor still exceeds the first current threshold / second current threshold after a single increase / decrease, the suction power is continued to be decreased / increased in the above manner. In this way, fine adjustment of the suction power can be achieved.

[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 blockage indicator to indicate that the floor brush is blocked. This allows the user to be promptly alerted to clean the floor brush when it becomes entangled and blocked by hair or other debris.

[0193] In some embodiments, the body 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. This allows the user to be promptly alerted to empty and clean the filter structure 100 when blockage occurs.

[0194] See Figures 30 to 39 As shown in the figure, an embodiment of this application provides a dust cup structure 1000 for a vacuum cleaner, including a cup body 1100 and a dust-throwing unit 1300. The cup body 1100 is configured with a first dust inlet 1111 and a dust storage chamber 1112. A cyclone separation unit 1200 is provided inside the cup body 1100. The cyclone separation unit 1200 is provided with a cyclone channel 1211 communicating with the first dust inlet 1111, so that the solid mixture enters the cyclone separation unit through the first dust inlet 1111. The ash-throwing unit 1300 and the cyclone separation unit 1200 are provided with a first snap-fit ​​rib 1221 and a first snap-fit ​​groove 1314 for snapping with the first snap-fit ​​rib 1221. The ash-throwing unit 1300 is constructed with an ash-throwing port 1321 that connects the cyclone channel 1211 and the ash storage chamber 1112. The solid mixture located in the cyclone channel 1211 enters the ash storage chamber 1112 through the ash-throwing 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 independent parts. The ash-throwing unit 1300 is detachably fixed to the cyclone separation unit 1200 through the snap-fit ​​of the first snap-fit ​​rib 1221 and the first snap-fit ​​groove 1314. The ash-throwing port 1321 protrudes from the outer surface of the outer wall 1220 of the cyclone, 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 waste can be stably temporarily stored 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 ash-throwing unit 1300 and the cyclone separation unit 1200, which are connected by the first snap-fit ​​rib 1221 and the first snap-fit ​​groove 1314, in other embodiments, the ash-throwing unit 1300 and the cyclone separation unit 1200 can also be connected by the second connecting part 1222 and the second snap-fit ​​rib 1316, thereby achieving a detachable connection between the ash-throwing unit 1300 and the cyclone separation unit 1200. The cyclone separation unit 1200 is provided with the second connecting part 1222, and the ash-throwing unit 1300 is provided with the second snap-fit ​​rib 1316 for engaging with the second connecting part 1222. Alternatively, the ash-throwing unit 1300 can have the second connecting part 1222, and the cyclone separation unit 1200 can have the second snap-fit ​​rib 1316 engaging with the second connecting part 1222. The structure of the second connecting part 1222 and the second snap-fit ​​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 form 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 that communicates with the air inlet of the vacuum cleaner's negative pressure motor. The cyclone cone 1230 has a plurality of first grids 1232 arranged around its circumference. The first grids 1232 can block solid mixtures from entering the first fluid channel 1231. A through groove 1233 between two adjacent first grids 1232 is used to connect the cyclone channel 1211 and the first fluid channel 1231. It can be understood that the first grid 1232 is composed of a plurality of through grooves 1233. Specifically, in order to ensure a high negative pressure in the cyclone channel 1211, i.e., low fluid loss in the entire system, the length of the through groove 1233 along the fluid flow direction is 28mm, the width of the lower part of the through groove 1233 is 3mm, and the width of the upper part of the through groove 1233 is 1.5mm.

[0197] Under the action of the negative pressure motor, large particles of waste have a large centrifugal force and will move in a circular motion along the outer wall 1220 of the cyclone. When they reach the ash throwing port 1321, they fly out of the cyclone channel 1211. Small particles of waste are blocked by the first grid 1232 and bounced when they reach the cyclone cone 1230, and then move in a circular motion from the ash throwing port 1321 to the ash storage chamber 1112.

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

[0199] See Figures 30 to 39 As shown, in one embodiment, the outer wall 1220 of the cyclone is arc-shaped, and the center of curvature of the outer wall 1220 coincides with the center of curvature of the cyclone cone 1230. For example, in this embodiment, the outer wall 1220 of the cyclone is a circle with a constant diameter, concentric with the cyclone cone 1230, ensuring 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, setting the outer wall 1220 of the cyclone to be circular also facilitates injection molding. The diameter of the inner wall 1210 of the cyclone can be adjusted according to the running speed of the fluid along the height direction. In other embodiments, the outer wall 1220 of the cyclone 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 from the outer surface of the cyclone cone 1230 to the outer wall 1220 of the cyclone is L1, the minimum distance from the outer wall 1220 of the cyclone to the end of the ash-throwing unit 1300 (i.e., the outermost part of the ash-throwing port 1321) is L2, and the maximum distance from the outer wall 1220 of the cyclone to the end of the ash-throwing unit 1300 is L3, wherein d is greater than L3, L3 is greater than L1, and L1 is greater than L2. For example, in this embodiment, d is 18mm, L1 is 15mm, L2 = 13mm, and L3 = 16mm.

[0201] See Figures 32 to 39 As shown, in one embodiment, the horizontal height of the ash discharge port 1321 is higher than the horizontal height of the first grid 1232, so that the particles moving in a circular motion lose centripetal force at their fastest speed and then fly out along the ash discharge port 1321 to the ash storage chamber 1112.

[0202] See Figures 32 to 39As shown, in one embodiment, the ash-throwing unit 1300 includes a main body 1310 and an ash-blocking part 1320 disposed on the main body 1310. The main body 1310 is used to connect with the outer wall 1220 of the cyclone, and the ash-blocking part 1320 extends relative to the main body 1310 in the direction toward the ash storage chamber 1112. When the cyclone channel 1211 is under negative pressure and there is a high-speed rotating airflow, it will attract the gas in the ash storage chamber 1112 to carry the garbage back to the cyclone channel 1211, which will affect the separation efficiency. By setting the ash-blocking part 1320 to extend relative to the main body 1310 in the direction toward the ash storage chamber 1112, the ash-blocking part 1320 has a certain length to prevent the backflow of dust in the ash storage chamber 1112.

[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 part 1311, the first connecting part 1311 including a first branch 1312 and two second branches 1313 respectively connected to both sides of the first branch 1312, the first branch 1312 and the two second branches 1313 cooperate to form a first snap-fit ​​groove 1314; the first branch 1312 abuts against the top of the first snap-fit ​​rib 1221. With this arrangement, the ash-throwing unit 1300 and the cyclone outer wall 1220 are snapped and fixed, and the connection between the two is more convenient.

[0204] See Figures 32 to 39 As shown, in one embodiment, the outer wall 1220 of the cyclone extends a second connecting portion 1222 in the direction toward the ash storage chamber 1112. The second connecting portion 1222 includes a third branch 1223 and a fourth branch 1224 that are vertically connected. The third branch 1223 and the fourth branch 1224 cooperate to form a second snap-fit ​​groove 1225. The main body 1310 is provided with a first opening groove 1315 and a second snap-fit ​​rib 1316 located in the first opening groove 1315. The groove wall of the first opening groove 1315 abuts against the third branch 1223, and the second snap-fit ​​rib 1316 is snapped into the second snap-fit ​​groove 1225.

[0205] See Figures 32 to 39As shown, in one embodiment, the second connecting portion 1222 includes a fifth branch 1226 connected to the bottom of the fourth branch 1224; the main body 1310 extends a third connecting portion 1317 in the direction toward the ash storage chamber 1112, the third connecting portion 1317 is provided with a second opening groove 1318 and a third snap-fit ​​rib 1319 located at the bottom of the second opening groove 1318; the fourth branch 1224 is snapped into the second opening groove 1318, and the third snap-fit ​​rib 1319 abuts against the bottom of the fifth branch 1226. The ash-throwing unit 1300 moves downward along the direction of gravity, allowing multiple snap-fit ​​ribs and corresponding snap-fit ​​grooves to engage, thereby securely fixing the ash-throwing unit 1300 to the cyclone outer wall 1220 and preventing the ash-throwing 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 latch 1450, which is used to engage with the cup body 1100. By moving the cover latch 1450, the dust cup cover 1400 can be opened, thereby allowing the dust in the dust storage chamber 1112 to be emptied, achieving deep cleaning of the cup body 1100. Further, the dust cup cover 1400 is provided with a cover notch 1440, and the cover latch 1450 is located within the cover notch 1440, allowing the user to easily operate the cover latch 1450 through the cover notch 1440, thereby facilitating the removal of the dust cup structure 1000; at the same time, it can also be docked with the 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 cover 1400 is elastically connected to a cover protrusion 1410, that is, a cover elastic member is provided between the dust cup cover 1400 and the cup body 1100. Through the action of the cover elastic member, the cover protrusion 1410 is kept in a protruding state. The vacuum cleaner body is provided with a cover engaging groove 4313 for engaging with the cover protrusion 1410. Through the engaging and fixing of the cover protrusion 1410 and the cover engaging groove 4313, the vertical position of the dust cup structure 1000 relative to the body is fixed.

[0208] See Figure 2 , Figure 12 , Figure 26 and Figure 27As shown, the dust cup cover 1400 is further rotatably connected to a cover rotating buckle 1420, which abuts against the cover protrusion 1410 to drive the cover protrusion 1410 out of the cover locking groove in a direction away from the cover locking groove. For example, if the user holds the cover rotating buckle 1420 and rotates it clockwise, the cover rotating buckle 1420 will push the cover protrusion 1410 away from the cover locking groove until the cover protrusion 1410 disengages from the cover locking groove. Then, the user applies upward force and lifts the dust cup structure 1000 using the dust cup handle 1430, allowing the dust cup structure 1000 to detach from the machine body. During installation, after the dust cup structure 1000 is placed into the machine body, the user removes the hand from the dust cup structure 1000, and the cover protrusion 1410 will engage with the cover locking groove under the action of the cover elastic element.

[0209] See Figures 33 to 39 As shown, in one embodiment, the cup body 1100 is provided with a first air outlet channel 1113 communicating with the first fluid channel 1231. The first air outlet channel 1113 has a first air outlet, and a first HEPA filter 1114 is installed at the first air outlet. The first air outlet channel 1113 is funnel-shaped. At least a portion of the cyclone separation unit is located above the first air outlet channel 1113, that is, the projections of the two on the horizontal plane at least partially overlap. After the airflow passes through the first grid 1232 of the cyclone cone 1230, it moves downward along the first fluid channel 1231 and enters the first air outlet channel 1113. At the tail of the first air outlet channel 1113, it is filtered by the first HEPA filter 1114, so that small particles passing through the first grid 1232 can be blocked and filtered by the first HEPA filter 1114, preventing small particles from entering the negative pressure motor and causing damage to components such as the impeller, rotor, and circuit board. The first HEPA filter 1114 is made of a material with certain air permeability. Generally, the larger the HEPA filter area, the less loss it causes to the entire fluid system. To ensure that the first HEPA filter 1114 will obstruct the fluid flow, in this embodiment, the ventilation area of ​​the first grid 1232 (the sum of the areas of each through slot 1233) is 1163.8 mm². The HEPA filter area is 7349.43 mm². Furthermore, to minimize the overall size, the negative pressure motor can be positioned behind the dust cup structure 1000, allowing airflow to directly enter the negative pressure motor. Simultaneously, because the upstream area of ​​this airflow segment is small and the downstream area is large, the first air outlet duct 1113 is flared, with its opening facing the first HEPA filter 1114, to ensure smooth airflow.

[0210] 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. 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 a circular air duct is smooth, it can reduce turbulence and vortices in the airflow, making the airflow more stable. Compared with air ducts of other shapes, the circular air duct has lower frictional resistance, which can reduce energy loss. Moreover, the circular air duct can make the airflow evenly distributed across the cross-section, reducing the non-uniformity of local airflow velocity, which helps to maintain a stable airflow and allow it to 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 revolution. In other embodiments, the spiral channel can be 720 degrees or larger, so that the cyclone channel 1211 can rotate several times. Meanwhile, because the cyclone channel 1211 is spiral upward, there will be a gap at the bottom of the cyclone channel 1211. This gap serves as part of the first air outlet channel 1113, which allows the fluid to be redirected better and saves space.

[0211] See Figure 30 As shown, in one embodiment, the vacuum cleaner body is provided with an anti-leakage elastic member and an anti-leakage component 1122 connected to the anti-leakage elastic member. The anti-leakage elastic member is used to drive the anti-leakage component 1122 to extend relative to the cup body 1100. In the extended state, the dust cup structure 1000 interferes with the body, thus preventing the installation of the cup body 1100 and the dust cup structure 1000 from being installed into the body. The first HEPA filter 1114 is provided with an anti-leakage baffle 1115, which abuts against the anti-leakage component 1122. That is, when the first HEPA filter 1114 is installed into the body, the anti-leakage baffle 1115 will press the anti-leakage component 1122, causing the anti-leakage component 1122 to retract relative to the cup body 1100. The dust cup structure 1000 and the body no longer interfere, thereby enabling the normal assembly of the dust cup structure 1000.

[0212] In one embodiment, the dust cup structure 1000 further includes a bottom cover latch 1510 and a dust cup bottom cover 1500 rotatably connected to the cup body 1100. One end of the bottom cover latch 1510 is engaged with the cup body 1100, and the other end is engaged with the dust cup bottom cover 1500 to lock the dust cup bottom cover 1500 and the cup body 1100. The bottom cover latch 1510 is configured to be operablely movable 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 dust cup bottom cover 1500 is provided with a bottom cover positioning groove 1520, and the vacuum cleaner body is provided with a bottom cover positioning protrusion 4311. The dust cup structure 1000 is positioned by the engaging cooperation between the bottom cover positioning protrusion 4311 and the bottom cover positioning groove 1520. In other embodiments, the dust cup bottom cover 1500 is also provided with a bottom cover positioning protrusion, and the vacuum cleaner body is provided with a bottom cover positioning groove 1520.

[0214] See Figure 2 , Figure 12 , Figure 26 and Figure 27 As shown, this application further provides a vacuum cleaner, including a body and a dust cup structure 1000 detachably connected to the body as described above; the body is provided with a first suction port communicating with a first dust 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 a cup-machine hook 1131, and the body is provided with a cup-machine positioning groove. The cup-machine hook 1131 can be provided at the upper end of the dust cup structure 1000, and the bottom cover positioning groove 1520 of the aforementioned embodiment can be provided at the bottom of the dust cup structure 1000. By providing fixing structures at both the upper and lower ends, the connection between the dust cup structure 1000 and the body is more stable and reliable. It can be understood that in other embodiments, the cup body 1100 may also be provided with a cup-machine positioning groove, and the body may be provided with a 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. Components such as the dust cup structure 1000 and the negative pressure motor are all installed inside the housing 4000. The handle assembly 6000 protrudes from the end of the housing 4000 opposite to the surface to be cleaned; that is, in use, the handle assembly 6000 protrudes from the top of the housing 4000. Thus, the handle assembly 6000 constitutes the first part of the vacuum cleaner's outer surface. The dust cup cover 1400 of the dust cup structure 1000 is quarter-circular, allowing it to form the second part of the vacuum cleaner's outer surface when installed inside the housing 4000. The housing 4000 then constitutes the third part of the vacuum cleaner's outer surface, resulting in a smoother and more aesthetically pleasing outer surface, saving space, and facilitating user operation. Furthermore, the housing 4000 has a battery mounting port 4330 at one end away from the dust cup structure 1000 along the first direction, and the battery pack assembly 5100 can be detachably installed inside the housing 4000 through the battery mounting port 4330.

[0216] Specifically, the housing 4000 includes a housing base 4100 and a housing top cover 4200 fixedly connected, with the top cover 4200 fixed to the end of the housing base 4100 facing away from the surface to be cleaned along a second direction. A battery mounting port 4330 is formed between the ends of the housing base 4100 and the top cover 4200 facing away from the dust cup structure 1000 along a first direction. The battery pack assembly 5100 can be installed and removed via the battery mounting port 4330 for easy 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 away from the housing 4000. The handle cover 6200 has a display notch 6220, and a display area 9000 for displaying target parameters such as dust concentration is located at 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 exposed through a display notch 6220. Specifically, the handle body 6100 is fixedly connected to the top of the housing top cover 4200, and the handle cover 6200 is connected to the top of the handle body 6100. A hollow cavity is formed between the handle cover 6200 and the handle body 6100 for mounting the display 6300. The 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, an embodiment of this application provides a cordless vacuum cleaner including a body 10, the body 10 including a housing 4000, a battery pack assembly and a negative pressure motor assembly 200 disposed inside the housing 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 a second direction; the negative pressure motor assembly 200 includes a negative pressure motor 3000 and a motor cover structure 2000 for mounting the negative pressure motor 3000, and the motor cover structure 2000 is provided with a first exhaust port 2170. The motor housing structure 2000 is provided with at least two second air outlet channels 2310, and a third air outlet channel 2110 is provided between the at least two second air outlet channels 2310, with the fluid flow directions in the third air outlet channel 2110 and the second air outlet channel 2310 being opposite. Understandably, the second air outlet channels 2310 and the third air outlet channel 2110 are used to exhaust air from the negative pressure motor 3000; wherein, 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. In this way, the airflow direction can be changed multiple times, and the airflow path is longer, resulting in a lower exhaust airflow velocity, reducing noise. Furthermore, 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. Moreover, the multi-segment 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 front motor cover 2100, a middle motor cover 2200, a rear motor cover 2300, and a rear cover 2400 arranged sequentially along the axial direction of the negative pressure motor 3000; see reference Figure 42 As shown, the motor housing 2200 is provided with a second air outlet 2210 for communication with the air outlet of the negative pressure motor 3000; see reference Figure 42 and Figure 40 As shown, the motor rear cover 2300 and the motor middle cover 2200 are connected, and the two together form a second air outlet channel 2310 that communicates with the second air outlet 2210; see reference. Figure 44 As shown, the motor front cover 2100 and the motor middle cover 2200 are connected to each other on the side opposite to the motor rear cover 2300. The motor front cover 2100 is provided with a third air outlet 2110 connected to the second air outlet 2310. Further, see [reference needed]. Figure 45As shown, the rear cover 2400 is connected to the side of the motor rear cover 2300 opposite to the motor middle cover 2200. The rear cover 2400 is provided with a fourth air outlet channel 2410, which connects to the third air outlet channel 2110 and the first exhaust port 2170. The fluid flow directions in the fourth air outlet channel 2410 and the third air outlet channel 2110 are opposite. The fluid flows sequentially 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, and is discharged through the first exhaust port 2170. Figure 40 As shown, taking two second air outlet channels 2310 as an example, distributed radially along the negative pressure motor 3000, the two second air outlet channels 2310 are respectively located on the left and right sides of the negative pressure motor 3000; the fluid in the two second air outlet channels 2310 flows axially around the negative pressure motor 3000 and flows from top to bottom until it enters the third air outlet channel 2110; for example, in Figure 44 From the perspective of the third air outlet duct 2110, the fluid flows axially around the negative pressure motor 3000, and the flow direction is from bottom to top, until it enters the fourth air outlet duct 2410; as Figure 45 As shown, the fluid in the fourth air outlet duct 2410 flows axially around the negative pressure motor 3000, and the flow direction is from top to bottom.

[0221] In the aforementioned motor cover structure 2000, fluid flows sequentially through the second air outlet 2210, the second air outlet channel 2310, the third air outlet channel, and the fourth air outlet channel 2410, and is discharged through the first exhaust port 2170. The second air outlet 2210 is located on the motor middle cover 2200, the second air outlet channel 2310 is located on the motor rear cover 2300, the third air outlet channel is located on the motor front cover 2100, and the fourth air outlet channel 2410 is located on the rear cover 2400. Taking the motor front cover 2100, motor middle cover 2200, motor rear cover 2300 and rear cover 2400 arranged from left to right as an example, the fluid flowing out of the motor middle cover 2200 first flows to the left into the motor rear cover 2300 and flows inside the motor rear cover 2300. Then the fluid flows to the left to the motor front cover 2100 and flows inside the motor front cover 2100. Then it flows to the right to the rear cover 2400 and flows inside the rear cover 2400. Moreover, the airflow direction is opposite in adjacent air outlet channels. That is to say, 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. Furthermore, the multi-segment design of the motor cover structure 2000 greatly improves the space utilization rate.

[0222] like Figure 43 and Figure 44 As shown, in one embodiment, both the third air outlet channel 2110 and the fourth air outlet channel 2410 are arranged axially around the negative pressure motor 3000. By arranging the air outlet channels around the axial direction of the negative pressure motor 3000, the airflow path is extended, resulting in a lower exhaust air velocity and reduced noise. Furthermore, the multiple air outlet channels also isolate the noise generated by the negative pressure motor 3000, greatly reducing the noise level of the negative pressure motor 3000.

[0223] like Figure 42 As shown, in one embodiment, the motor housing 2200 includes an inner wall 2201 and an outer wall 2202 surrounding the inner wall 2201. A partition 2203 is provided between the inner wall 2201 and the outer wall 2202. The partition 2203 divides the cavity formed by the inner wall 2201 and the outer wall 2202 into at least two air outlet channels. The fluid flow directions of the two adjacent air outlet channels are different. By dividing the air outlet channels in the motor housing 2200 into multiple segments through the partition 2203, the space utilization rate is greatly improved.

[0224] See Figures 41 to 44 As shown, in one embodiment, the motor front cover 2100, motor middle cover 2200, and motor rear cover 2300 are respectively provided with a front cover mounting cavity 2120, a middle cover mounting cavity 2260, and a rear cover mounting cavity 2340, which together constitute the motor mounting cavity. A second air outlet 2210 is disposed on the cavity wall of the middle cover mounting cavity 2260. The second air outlet 2210 can be located within one-half to one-third of the axial length of the negative pressure motor 3000, ensuring that the airflow from the negative pressure motor 3000's air outlet can be quickly discharged, preventing the negative pressure motor 3000 from overheating.

[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 cavity wall of the rear cover mounting cavity 2340. In one embodiment, there are two second air outlet channels 2310, which are arranged circumferentially at intervals along the negative pressure motor 3000, that is, the two second air outlet channels 2310 are distributed radially along the negative pressure motor 3000, and the two second air outlet channels 2310 are arranged in a Y-shape. The arrangement of multiple second air outlet channels 2310 can increase the airflow space, lengthen the airflow path, and reduce fluid resistance.

[0226] See Figures 40 to 42As shown, in one embodiment, the second air outlet 2210 includes two outlets, 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 included angle between the centerlines of the two second air outlets 2210 is 30 degrees to 90 degrees, and further, the included angle between the centerlines of the two second air outlets 2210 can be 67 degrees. The dispersed arrangement of the second air outlets 2210 helps with heat dissipation within the air outlet channel and makes reasonable use of 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; see reference Figure 42 As shown, the motor housing 2200 is provided with a first housing cavity 2220 and a second housing cavity 2230 that are isolated from each other. The first housing cavity 2220 connects the second air outlet 2210 and the first rear housing cavity 2311; the second housing cavity 2230 connects the second air outlet channel 2310 and the third air outlet channel. In this way, airflow is realized within the motor housing 2200, the motor rear housing 2300, and the rear cover 2400, and an air outlet channel with guiding airflow direction is formed, so that the airflow can not only flow circumferentially along the negative pressure motor 3000, but also move axially along the negative pressure motor 3000.

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

[0229] See Figures 42 to 40 As shown, in one embodiment, the motor inner cover 2200 and the motor rear cover 2300 are respectively provided with a third inner cover cavity 2240 and a third rear cover cavity 2320, which connect the third air outlet channel and the fourth air outlet channel 2410. In this way, the rear cover 2400 and the motor front cover 2100 are connected, allowing airflow to move from inside the rear cover 2400 along the axial direction of the negative pressure motor 3000 to the motor front cover 2100, and also extending the air duct.

[0230] See Figure 41As shown, in one embodiment, the first exhaust vent 2170 is located on the front cover 2100 of the motor, and the first exhaust vent 2170 and the second exhaust vent 2210 are located on opposite sides of the negative pressure motor 3000 in the radial direction. This extends the airflow path within the motor cover structure 2000, reduces fluid loss, and lowers noise. The front cover 2100 has a first front cover cavity 2180 communicating with the first exhaust vent 2170; see reference... 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 in 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 along the axial direction of the negative pressure motor 3000, and the fluid flow directions in the third middle chamber 2240 and the fourth middle chamber 2250 are opposite. The third middle chamber 2240 and the third rear chamber 2320 have essentially the same shape, which facilitates smoother fluid flow and reduces fluid loss caused by sudden wall expansion. Furthermore, the first front chamber 2180, the fourth middle chamber 2250, and the fourth rear chamber 2330 are arranged along the axial direction of the negative pressure motor 3000, and their shapes are essentially the same, thereby reducing velocity loss caused by fluid flowing through uneven walls. The third middle chamber 2240 and the fourth middle chamber 2250 are located on opposite sides of the radial direction of the negative pressure motor 3000, thus extending the airflow path. Specifically, the fluid passes through the second air outlet 2210, enters the first inner cover cavity 2220 of the motor inner cover 2200 and the first rear cover cavity 2311 of the motor rear cover 2300, then passes through the second air outlet channel 2310 extending circumferentially along the negative pressure motor 3000, and enters upward into the second inner cover cavity 2230 of the motor inner cover 2200; then it enters upward into the third air outlet channel inside the motor front cover 2100, where the two airflows flowing out of the two second air outlets 2210 mix in the third air outlet channel of the motor front cover 2100; then... The airflow flows downwards, passing sequentially through the third inner cover cavity 2240 within the motor inner cover 2200 and the third rear cover cavity 2320 within the motor rear cover 2300. It then enters the fourth exhaust channel 2410 formed by the motor rear cover 2300 and the rear cover 2400. Subsequently, it flows upwards along the fourth rear cover cavity 2330 of the motor rear cover 2300 and the fourth inner cover cavity 2250 of the motor inner cover 2200, reaching the first front cover cavity 2180 of the motor front cover 2100, and then exits outside the motor cover structure 2000 through the first exhaust port 2170. Specifically, the airflow can be filtered by the exhaust HEPA filter installed inside the cordless vacuum cleaner before being discharged outside the vacuum cleaner body 10. The airflow not only circles around the circumference of the motor housing structure 2000 multiple times, but also circles along the axial direction of the motor housing 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. Furthermore, the multi-segment design of the motor housing structure 2000 significantly improves the space utilization rate.

[0232] See Figure 40As shown, in one embodiment, the motor front cover 2100 is provided with a front cover sealing groove 2130, which 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 is press-fitted with the cavity wall of the mounting cavity of the body 10. This mounting cavity of the body 10 is the mounting cavity for installing the battery pack assembly and the motor cover structure 2000. The cavity wall of this mounting cavity is located between the first air outlet of the dust cup structure and the motor cover structure, allowing the airflow drawn in by the cordless vacuum cleaner to enter the dust cup structure. After being filtered and separated by the dust cup structure, the airflow enters the air inlet of the negative pressure motor 3000 through the first air outlet of the dust cup structure, ensuring a sealing effect, and then flows 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 damper 2150, which can be made of soft rubber, is provided inside the front cover 2100 of the motor to reduce the axial vibration of the negative pressure motor 3000, thereby reducing noise. Furthermore, a rear cover damper 2350, also made of soft rubber, can be provided inside the rear cover 2300 of the motor to reduce axial vibration and noise. The rear cover damper 2350 can be cup-shaped to wrap around the end of the negative pressure motor, reducing both axial and circumferential vibration. More specifically, the front cover damper 2150 and the rear cover damper 2350 do not completely overlap axially with the negative pressure motor 3000, thus ensuring the airflow 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 passage hole 2371 and a cover wire passage hole 2431. The wires of the negative pressure motor 3000 pass through the rear cover wire passage hole 2371 and the cover wire passage hole 2431 and are connected to the circuit board. Furthermore, the rear cover wire passage hole 2371 and the cover wire passage hole 2431 are also respectively connected with a rear cover wire plug 2372 and a cover wire plug 2432, which are used to 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. Further, see [reference needed]. Figure 42 and Figure 40 As shown, one of the motor inner cover 2200 and the motor rear cover 2300 is provided with an inner cover buckle 2272, and the other is provided with a rear cover slot 2361 for engaging with the inner cover buckle 2272. (See reference...) 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 engagement of the buckle and slot simplifies the assembly of the motor cover structure 2000, and saves more space compared to screw connections. Furthermore, the joints between adjacent covers (motor front cover 2100, motor middle cover 2200, and motor rear cover 2300 are collectively referred to as covers) are respectively provided with slots and ribs. The engagement of the slots and ribs achieves a seal between adjacent covers.

[0236] See Figure 47 As shown, in one embodiment, the body 10 is provided with a suction port assembly that communicates with the air inlet of the negative pressure motor 3000. After the airflow enters the motor cover structure 2000, it 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. Moreover, 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. Furthermore, the multi-segment design of the motor cover structure 2000 significantly 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 assembly are radially spaced apart from each other. Specifically, the central axis Z2 of the suction 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 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 assembly is 7mm. Thus, the second air outlet channel 2310 has a larger air passage area, which can reduce fluid loss and reduce noise. At the same time, the negative pressure motor 3000 and the first air outlet of the dust cup structure are approximately coaxial, making the air duct smoother 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 can also be an AC motor.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
