[0058] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0059] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0060] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0061] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0062] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0063] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0064] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0065] The present application provides a portable vacuum cleaner (10a, 10b) that can be used as a vehicle-mounted vacuum cleaner in a vehicle to absorb dust and other foreign matter in the vehicle, thereby maintaining a clean environment within the vehicle. In addition to being carried in a vehicle, the portable vacuum cleaner can also be carried around or used to clean environments in offices and other spaces at any time.

[0066] Figures 1 to 6 disclose an embodiment of a portable vacuum cleaner 10a, and Figures 7 to 19 disclose an embodiment of a portable vacuum cleaner 10b. The common components of the portable vacuum cleaner 10a and the portable vacuum cleaner 10b are not distinguished in numbering and naming.

[0067] As shown in Figures 1 to 18, the portable vacuum cleaner (10a, 10b) mainly includes a housing 100, a battery pack coupling 110, a dust box 210, a dust suction tube 300, a motor 400, a battery pack 500, and a dust suction accessory 600. The housing 100 is the main installation component of the portable vacuum cleaner. The battery pack coupling 110, the dust box 210, the dust suction tube 300, the motor 400, the battery pack 500, and the dust suction accessory 600 are all installed inside the housing 100 or on the outer wall of the housing 100. In one embodiment, at least two of the battery pack coupling 110, the dust box 210, the dust suction tube 300, the motor 400, the battery pack 500, and the dust suction accessory 600 are connected together through the housing 100.

[0068] The battery pack connector 110 is used to mount the battery pack 500. It should be noted that the battery pack connector 110 can be integrally formed with the housing 100 during manufacture, or it can be a separate component and then fixed to the housing 100. The dust box 210 is used to store dust and other foreign matter collected from the vehicle interior. The dust box 210 is connected to the housing 100 or mounted within the housing 100. The dust box 210 can also be formed by the housing 100. The dust suction tube 300 has one end as a connection end and the other end as a dust collection end. The connection end of the dust suction tube 300 is connected to the dust box 210, and the dust collection end of the dust suction tube 300 can be connected to at least the dust collection accessory 600. The motor 400 is used to generate negative pressure within the portable vacuum cleaner. The battery pack 500 is connected to the motor 400 and is used to power the motor 400. The battery pack 500 is detachably connected to the housing 100. In some embodiments, the battery pack 500 can also be a built-in battery pack, thus being non-detachably mounted within the housing 100.

[0069] The portable vacuum cleaner operates as follows: a motor 400 drives blades 410 to rotate at high speed, creating a negative pressure inside housing 100. Under this negative pressure, foreign matter inside the vehicle is sucked into the dust collection tube 300 by the dust collection accessory 600. The foreign matter then passes through the dust collection tube 300 and into the dust box 210. Under this negative pressure, the air in the dust box passes through the filter element and is discharged from the motor. To remove foreign matter from dust box 210, the dust box 210 can be disassembled or opened to remove the foreign matter, allowing it to escape from the portable vacuum cleaner.

[0070] To facilitate description of the structure of the portable vacuum cleaner, the front-to-back direction of the portable vacuum cleaner is defined as the x-direction in Figure 1 , the left-to-right direction of the portable vacuum cleaner is defined as the y-direction in Figure 1 , and the up-down direction of the portable vacuum cleaner is defined as the z-direction in Figure 1 . The x-, y-, and z-directions are perpendicular to each other.

[0071] In conjunction with Figures 14 and 15, the portable vacuum cleaner is substantially rectangular in shape, and the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 85 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 80 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 75 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 70 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 65 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 60 mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 55 mm. In other words, the minimum of the maximum thickness of the portable vacuum cleaner in any direction is greater than or equal to 85 mm, 80 mm, 75 mm, 70 mm, 65 mm, or 60 mm. In other words, for a portable vacuum cleaner, it should be noted that the rectangular parallelepiped here refers to a state in which the vacuum tube 300 of the portable vacuum cleaner is stored close to the shell 100 and the dust cover 220 is closed (as shown in FIG1 ).

[0072] In some embodiments, the thickness of the portable vacuum cleaner along the x-direction is less than or equal to 65 mm. This configuration reduces the thickness of the portable vacuum cleaner and reduces the space it occupies. On the one hand, the portable vacuum cleaner can be stored in a storage pocket behind a seat, in the storage space at a vehicle door, or in a storage box in the front row of a vehicle, making it easy to store. On the other hand, one end of the portable vacuum cleaner can be placed in the user's thumb, making it easier for the user to hold the portable vacuum cleaner. This makes it easier for the user to operate the portable vacuum cleaner in confined environments such as a car, thereby improving the user experience.

[0073] In some specific embodiments, the thickness T of the portable vacuum cleaner along the x-direction is less than or equal to 60 mm; in some other specific embodiments, the thickness T of the portable vacuum cleaner along the x-direction is less than or equal to 55 mm; in other specific embodiments, the thickness T of the portable vacuum cleaner along the x-direction is less than or equal to 50 mm.

[0074] In some embodiments, the length L of the portable vacuum cleaner along the y direction is less than or equal to 300 mm, or less than or equal to 280 mm, or less than or equal to 250 mm. This configuration further reduces the volume of the portable vacuum cleaner, making the portable vacuum cleaner more compact.

[0075] In some embodiments, the height H of the portable vacuum cleaner along the z direction is less than or equal to 250 mm, or less than or equal to 240 mm, or less than or equal to 230 mm, or less than or equal to 220 mm. This configuration further reduces the volume of the portable vacuum cleaner, making the portable vacuum cleaner more compact.

[0076] In some embodiments, the outer diameter of the motor 400 is less than or equal to 50 mm, or less than or equal to 45 mm, or less than or equal to 40 mm.

[0077] In some embodiments, a ratio of a thickness of the portable vacuum cleaner along the front-to-back direction to a thickness of the battery pack 500 along the front-to-back direction is greater than or equal to 0.5.

[0078] As shown in FIG6 , in some embodiments, the dust box 210 is cylindrical. As shown in FIG13 , in some other embodiments, the dust box 210 is cubical. In some other embodiments, the dust box 210 is partially cylindrical, with the remaining portion extending from one side of the cylinder and connected to the dust collection tube 300, i.e., the dust box 210 is a special-shaped box similar to a "tree branch."

[0079] In order to achieve rapid assembly and disassembly of the battery pack 500 on the battery pack coupling portion 110, the battery pack coupling portion 110 includes a plug-in structure 111, and the battery pack 500 is plugged into the plug-in structure 111 along a first direction, which is parallel to the z-direction. One of the battery pack coupling portion 110 and the battery pack 500 is provided with a plug-in block and the other is provided with a plug-in slot. Of course, in some other embodiments, the first direction may also be parallel to the y-direction or the x-direction, or form a certain angle with the z-direction. In other words, in addition to plugging and unplugging the battery pack 500 in the up-down direction, left-right direction, or front-back direction, the battery pack 500 may also be plugged and unplugged in other directions, which is not limited here.

[0080] In some embodiments, a first projection of the battery pack 500 in a first plane perpendicular to the z-direction (i.e., in the xoy plane) falls within a second projection of the portable vacuum cleaner in the first plane. In other words, after the battery pack 500 is mounted to the battery pack coupling portion 110, it does not extend beyond the boundaries of the housing 100 in the x-direction.

[0081] In some embodiments, the portable vacuum cleaner can be powered by different battery packs, for example, a first battery pack or a second battery pack. That is, the battery pack connector 110 can accommodate either the first battery pack or the second battery pack. The first battery pack and the second battery pack have different electrical parameters. These electrical parameters may include rated voltage, maximum output power, and so on. In other embodiments, the volumes of the first battery pack and the second battery pack may also be different.

[0082] In some specific embodiments, the output power of the first battery pack is greater than or equal to 50W and less than or equal to 200W; the output power of the second battery pack is greater than or equal to 50W and less than or equal to 200W. For example, the output power of the first battery pack can be 50W, 80W, 100W, 120W, 150W, or 200W, and the output power of the second battery pack is 50W, or 100W, or 120W, or 150W, or 200W. The output power of the battery pack 500 is the working power of the portable vacuum cleaner. That is, the output power of the portable vacuum cleaner at the maximum speed gear is greater than or equal to 50W and less than or equal to 200W, and can specifically be 80W, 100W, 110W, 120W, 130W, 140W, or 150W.

[0083] In some specific embodiments, the rated voltage of the first battery pack and the rated voltage of the second battery pack can be any voltage value between 12 V and 40 V. For example, the rated voltage of the first battery pack can be 8 V, 12 V, 16 V, 20 V, 24 V, 30 V, 36 V, 40 V, etc.; the rated voltage of the second battery pack can be 8 V, 12 V, 16 V, 20 V, 24 V, 30 V, 36 V, 40 V, etc.

[0084] In order to facilitate the user to hold the portable vacuum cleaner, part of the structure on the shell 100 is concave inward or convex outward to form a gripping portion 140 for the user to hold.

[0085] The third projection of the gripping portion 140 in the first plane perpendicular to the z-direction falls within the second projection of the portable vacuum cleaner in the first plane.

[0086] In the technical solution shown in Figures 7 to 14 , the dust suction tube 300 has one end connected to the housing 100, namely, the connector 700. The dust suction tube 300 also includes another end opposite the connector 700, namely, an air inlet 161 on the dust suction tube 300 for allowing external airflow to flow into the dust suction tube 300. The opening formed at the connection between the connector 700 and the housing 100 is the dust inlet 170, and the opening formed by the air inlet 161 is the dust suction port 160. In other words, the dust inlet 170 is located at the connection between the dust suction tube 300 and the dust collection device 200, and allows airflow from the dust suction tube 300 to flow into the dust collection device 200.

[0087] The housing 100 has a dust cover 220 opposite the dust box 210. The dust box 210 has a dust outlet. The dust cover 220 is connected to the dust outlet in an openable and closable manner. In some embodiments, the dust box cover can be rotated relative to the dust box 210 by pressing the dust box cover, thereby opening or closing the dust outlet.

[0088] A filter element 240 is also provided in the dust box 210. The filter element 240 can filter the air and filter foreign matter in the air into the dust box 210. One end of the filter element is connected to the rear end of the motor 400. The rotation of the motor 400 generates negative pressure, so that the gas in the filter element is discharged from the exhaust port 150 on the side of the motor 400.

[0089] In order to facilitate the dumping of foreign matter in the dust box 210 into the trash can without contaminating the user's hands during the dumping process, the dust collecting device 200 also includes a first button 230. By operating the first button 230, the dust cover 220 can be moved to open the dust outlet 250. The operation here can be pressing, touching, pushing, etc. As for how to operate the first button 250 to drive the dust box cover to move, it is a related technology and will not be described in detail here. In one embodiment, the dust collecting device 200 of the portable dust collection device has a one-button pop-up function, that is, the dust cover 210 can be quickly popped out by operating the first button 230. When in use, the user can invert the portable dust collection device and aim it at the trash can, and operate the first button 230 to achieve rapid discharge of dust.

[0090] In one embodiment, the portable dust collection device further includes a second button 260, by operating the second button 260, the dust box 210 and / or the filter element 240 located in the dust box 210 can be unloaded. The operation here can be rotation, pressing or touching. In one embodiment, as shown in Figure 9, the filter element 240 is disassembled by rotating the second button 260. As for how to unload the dust box 210 or the filter element 240 by operating the second button 260, it is a related technology and will not be described in detail here. In addition to being cylindrical or conical as disclosed in this application, the filter element 240 can also be cubic in shape, which is not limited here.

[0091] Of course, in some other embodiments, the first key 230 and the second key 260 may be integrated into one key, and the movement of the dust cover 220, the unloading of the dust box 210 or the unloading of the filter element 240 may be achieved by pressing for different durations.

[0092] As shown in Figure 6, the central axis of the motor 400 is the motor axis a, and the motor 400 can rotate around the motor axis. The central axis of the dust box 210 is the dust box axis b, and the motor axis a is arranged parallel to the dust box axis b. In one embodiment, the motor axis a of the motor 400 and the central axis b of the dust box 210 can also be arranged collinearly. Continuing with reference to Figure 6, the battery pack 500 is arranged on one side of the motor 400 and the dust box 210, and the dust collection accessories 600 are arranged on the other side of the battery pack 500, that is, the dust collection accessories 600, the battery pack 500, the motor 400, and the dust box 210 assembly are arranged in sequence in the y direction. Such an arrangement makes it possible to arrange the various components in the portable dust collection device reasonably, making it easier to miniaturize the portable dust collection device.

[0093] In some embodiments, the projections of the motor 400, dust box 210, dust collection tube 300, and battery pack 500 on a vertical plane perpendicular to the front-to-back direction (i.e., the yoz plane) do not overlap. In other words, these components are essentially flat inside and outside the housing 100, thereby ensuring a relatively low thickness of the entire vacuum device.

[0094] 6 and 17 , the housing 100 is provided with an exhaust port 150, which is located near the motor 400. In some embodiments, the exhaust port 150 is located directly above the motor 400. In other embodiments, a portion of the housing 100 is recessed inward to form a receiving groove 130, which is used to accommodate the dust collection tube 300, and the exhaust port 150 is located within the receiving groove 130.

[0095] The following is an additional description of the different technical solutions of the portable vacuum cleaner 10b disclosed in Figures 7 to 13 and the portable vacuum cleaner 10a disclosed in Figures 1 to 6.

[0096] The portable vacuum cleaner 10b is formed by connecting a device body 101 and a vacuum tube 300. The device body 101 includes at least a shell 100, a battery pack 500 and a motor 400. The shell 100 forms a storage space. The storage space of the shell 100 accommodates at least the motor 400 and the dust box 210. At least the shell 100 opposite to the dust box 210 in the front-to-back direction is set as a transparent part. The battery coupling portion 110 is formed in the device body 101 and is used to install the battery pack 500. The dust box 210 is arranged in the device body 101, and the vacuum tube 300 can be stored in the device body 101. The mass of the device body 101 is less than or equal to 3 kg. In some embodiments, the mass of the device body 101 can be 2.8 kg, 2.5 kg, 2.2 kg, 2 kg, 1.7 kg or 1.5 kg.

[0097] In this embodiment, a dust guide channel 270 is provided in the shell 100, and a filter element 240 for filtering the airflow is provided in the dust box 210. The dust guide channel 270 connects the filter element 240 and the motor 400. After the airflow enters the dust box 210, it is filtered by the filter element 240 and flows into the dust guide channel 270, and then flows to the motor 400 through the dust guide channel 270.

[0098] A dust guide channel 270 is provided in the accommodation space formed by the contact between the dust box 210 and the shell 100. The filter element 240 is wrapped by a circle of filter paper 280 to form a cylindrical or conical shape. The middle of the filter element 240 is a hollow air storage structure 290. When the airflow to be filtered flows from the outside of the filter paper 280 into the air storage structure 290 on the inside of the filter paper 280, impurities and other substances in the airflow are blocked outside the filter paper 280. The starting end of the dust guide channel 270 is located at the bottom of the air storage structure 290 of the filter element 240, and the ending end is connected to the airflow connecting pipe 420 between the motor 400 and the shell 100. When the inhaled airflow falls from the filter element 240 to the dust guide channel 270, the displacement direction of the airflow is from the shallower position of the dust box 210 to the deeper position of the dust box 210. The airflow flows in from the dust suction port 160 of the dust suction pipe 300, flows into the dust box 210 from the dust inlet 170, and then flows into the dust guide channel 270 after being filtered by the filter element 240. After flowing into the motor 400 in the dust guide channel 270, it flows to one end of the blade 410 of the motor 400, and is then discharged from the exhaust port 150 (see Figures 6, 13 and 17).

[0099] The maximum depth of the dust box 210 along the front-to-back direction is greater than or equal to 30 mm and less than or equal to 80 mm. In some embodiments, the maximum depth of the dust box 210 along the front-to-back direction may be 40 mm, 45 mm, 50 mm, 55 mm, or 60 mm. The maximum depth of the dust box 210 is defined as the dust box depth T1. The ratio of the dust box depth T1 to the thickness T of the portable dust collection device is greater than or equal to 0.7 and less than or equal to 1.1. In some embodiments, the ratio of the dust box depth T1 to the thickness T of the portable dust collection device may be 0.8, 0.85, 0.9, or 1.

[0100] When the dust cover 220 is open, the user points the front of the portable vacuum cleaner 10b toward a trash can and, relying on the inertia of the dust cover 220 and gravity, pours out the dust and impurities in the dust box 210. The plane where the dust outlet 250 is located is perpendicular to the front-to-back direction, and the dust outlet 250 discharges dust generally from the rear side of the portable vacuum cleaner 10b toward the front. In other words, by pointing the portable vacuum cleaner 10b toward the trash can in the position shown in Figure 9 and pressing the first button 230, the user can easily empty the dust.

[0101] The area of ​​the dust outlet 250 is greater than or equal to 3500 square millimeters. In some embodiments, the area of ​​the dust outlet 250 can be 3600 square millimeters, 3800 square millimeters, 4200 square millimeters, 4500 square millimeters, 5000 square millimeters, etc. The ratio of the area of ​​the dust outlet 250 of the dust box 210 to the maximum depth of the dust box 210 along the front-to-back direction is greater than or equal to 80. In some embodiments, the ratio of the area of ​​the dust outlet 250 of the dust box 210 to the maximum depth of the dust box 210 along the front-to-back direction is greater than or equal to 100, 120, or 140. It should be noted that the value of this ratio does not include units, and during the calculation process, it is necessary to ensure that the area and depth use the same series of units. For example, when the unit of the area is square millimeters, the unit of the depth should be millimeters. This setting can make the dust exhaust efficiency of the dust box 210 higher.

[0102] In some common vacuum cleaners, the arrangement of the dust box 210 and motor 400 is similar to that shown in Figure 7 , where the motor 400 and dust box 21 are arranged in a "1" shape and directly connected, with airflow flowing directly from the dust box 21 into 400. Therefore, if portable vacuum cleaners in related art want to be sufficiently "thin," the area of ​​their dust outlet 250 will also be affected by the thickness of the entire device, making it difficult to enlarge the dust outlet 250. This solution changes the dust box 210 and motor 400 from overlapping to being "flattened" on a plane perpendicular to the vertical direction, simultaneously meeting user demands for a large dust outlet and a thinner device.

[0103] It should be noted that the extension direction of the dust box 210 here is the direction of the airflow falling when it moves in the dust box 210, that is, the direction from front to back.

[0104] The volume within the area formed by the outer boundary of the housing 100 is defined as the total volume of the portable dust collection device 10b, and the total volume is less than or equal to 4500 cubic centimeters. In one embodiment, the total volume of the portable dust collection device 10b is less than or equal to 4000 cubic centimeters. In one embodiment, the total volume of the portable dust collection device 10b is less than or equal to 3500 cubic centimeters. In one embodiment, the total volume of the portable dust collection device 10b is less than or equal to 3000 cubic centimeters.

[0105] The portable vacuum cleaner 10b also includes a switch device 800 for the user to control the operating state of the motor 400. The switch device includes a first operating member 810 and a second operating member 820. The first operating member 810 is used to turn the motor 400 of the portable vacuum cleaner 10b on or off, while the second operating member 820 is configured to adjust the suction capacity. When the user presses the first operating member 810, the portable vacuum cleaner 10b operates at a gear with maximum suction capacity. When the user presses the second operating member 820, the suction capacity is reduced. In another embodiment, when the user presses the first operating member 810, the portable vacuum cleaner 10b operates at a gear with moderate suction capacity. When the user presses the second operating member 820, the suction capacity is adjusted to maximum.

[0106] In some embodiments, the exhaust port 150 can be connected to an inflatable accessory 310 (see FIG. 18 ) to inflate an external device. Optionally, the inflatable accessory is an inflatable nozzle, and the external device can be a swimming ring, a balloon, or the like.

[0107] In some embodiments, the housing 100 is in a cubic shape, the receiving slots 130 are U-shaped slots formed on multiple sidewalls of the housing 100, and the dust collection tube 300 is wound around the housing 100 and is generally curved in a U-shape. It should be noted that if the cubic boundary of the housing 100 is provided with chamfers or fillets with a large radius, but still exhibits the "flat" structure of this application, it should also fall within the scope of protection of this application.

[0108] In some embodiments, the dust suction tube 300 is fixed in the receiving groove 130 by magnetism; in some other embodiments, the dust suction tube 300 is fastened in the receiving groove 130 by snap-fitting.

[0109] In order to facilitate the storage of the dust suction tube 300 in the receiving groove 130 , in some embodiments, at least a portion of the dust suction tube 300 is a hose, so that the dust suction tube 300 can be bent and deformed.

[0110] In some embodiments, the dust suction tube 300 is a telescopic tube, and the telescopic length of the dust suction tube 300 is greater than or equal to 40 cm and less than or equal to 150 cm. By setting the dust suction tube 300 as a telescopic tube, after the dust suction tube 300 is taken out of the receiving groove 130, all components of the portable dust suction device except the dust suction tube 300 and the dust suction accessory 600 can remain stationary. Only the telescopic nature of the dust suction tube 300 allows the dust suction accessory 600 to be moved to the surface or gap to be vacuumed for vacuuming. This avoids the user holding the shell 100, further improving the user experience. As shown in Figure 16, in order to facilitate the placement of the portable dust suction device and improve the stability of the portable dust suction device in the vehicle, in some embodiments, the portable dust suction device also includes a clamping member 330, which can clamp and fix the portable dust suction device to an external structure. The external structure here specifically refers to components inside the vehicle, such as storage bags on the seat copies, storage spaces in the car doors, etc. Clamping and fixing the portable dust suction device on the external mechanism can prevent the portable dust suction device from being damaged due to shaking during the movement of the vehicle.

[0111] In some embodiments, the clamping member 330 is fixedly connected to the outer wall surface of the shell 100 or detachably connected to the outer wall surface of the shell 100. The fixed connection method includes but is not limited to bonding and welding, and the detachable connection method includes but is not limited to screw connection, magnetic attraction, etc. Of course, in addition to being provided on the shell 100, the clamping member can also be provided on the battery pack 500 or the dust suction tube 300, as long as the portable dust suction device can be fixed. The number of clamping members 330 can be set to one or more according to needs. The number of clamping members 330 shown in Figure 16 is two. As shown in Figure 9, two mounting holes 331 are provided on the shell 100, and the screws pass through the clamping member 330 and are screwed into the mounting holes 331 to fix the clamping member 330 and the shell 100.

[0112] In some embodiments, the clamp 330 is a metal clip or a plastic clip.

[0113] In some embodiments, the clamp 330 is a spring clamp or a duckbill clamp.

[0114] In some embodiments, in order to improve the stability of the portable vacuum cleaner when mounted on an external structure, the clamping member 330 is disposed at the center of gravity of the portable vacuum cleaner, or above the center of gravity of the portable vacuum cleaner.

[0115] Of course, in addition to using the clamping member 330 to fix the portable vacuum cleaner, a magnetic member can also be provided on the portable vacuum cleaner to use the magnetic member to adsorb the portable vacuum cleaner onto metal parts in the vehicle, thereby fixing the portable vacuum cleaner and preventing the portable vacuum cleaner from being damaged due to shaking during the movement of the vehicle.

[0116] In order to stably place the portable vacuum cleaner on an external placement platform, the portable vacuum cleaner has at least one placement surface 180 (see Figures 2 and 5), which can be placed face down on the external placement platform. The external placement platform can be a console, seat, or storage box in a vehicle.

[0117] The battery pack 500 is inserted and removed in the vertical direction of the portable vacuum cleaner. In some embodiments, the battery pack 500 can be inserted and removed in any direction within the vertical plane (i.e., the yoz plane) formed by the vertical and left-right directions of the portable vacuum cleaner. This arrangement has the advantage that when replacing battery packs 500 with different capacities and thicknesses, the outer shell of the battery pack 500 can be lower than the shell 100 or substantially flush with the shell 100, thereby not affecting the flatness of the overall appearance of the portable vacuum cleaner and its stability when placed.

[0118] To increase the placement flexibility of the portable vacuum cleaner, in some embodiments, the placement surface 180 includes a first placement surface 181 and a second placement surface 182. The first placement surface is formed on the battery pack 500, and the second placement surface is formed on the housing 100. The second placement surface 182 is parallel or perpendicular to the first placement surface 181. In other embodiments, the number of placement surfaces can be increased as needed. For example, the portable vacuum cleaner in the stored state can be designed into a cube, thereby providing the portable vacuum cleaner with six placement surfaces.

[0119] In the portable vacuum cleaner 10b, the dust cover 220 is arranged on the other side opposite to the placement surface 180, or in other words, when the dust cover 220 is located on the front side of the portable vacuum cleaner 10b, the placement surface 180 is the rear side surface of the shell 100 of the portable vacuum cleaner 10b.

[0120] The motor axis a of the motor 400 is substantially perpendicular to the front-to-back direction of the portable vacuum cleaner 10b, and is also substantially perpendicular to the left-to-right direction of the portable vacuum cleaner 10b. The dust box axis b of the dust box 210 is perpendicular to the motor axis a. The dust box axis b is perpendicular to the placement surface 180, and the direction in which the dust box axis b extends corresponds to the depth of the dust box 210. In this embodiment, the direction of the dust box axis b also corresponds to the direction of the central axis of the filter element 240. The projections of the motor 400 and the dust box 210 on the plane of the outer surface of the dust cover 220 do not overlap. The projections of the motor 400 and the battery pack 500 on the plane of the outer surface of the dust cover 220 do not overlap. The projections of the dust box 210 and the battery pack 500 on the plane of the outer surface of the dust cover 220 do not overlap. The projections of the motor 400, dust box 210, and battery pack 500 on the plane of the outer surface of the dust cover 220 do not overlap. The projections of the motor 400, dust box 210, battery pack 500, and dust collection tube 300 on the plane of the outer surface of the dust cover 220 do not overlap. The plane of the outer surface of the dust cover 220 (also known as the yoz plane) is also a vertical plane perpendicular to the front-to-back direction. In this embodiment, the dust discharge port 250 forms a dust discharge plane that is parallel to the outer surface of the dust cover. In other words, the projections of at least two of the motor 400, dust box 210, battery pack 500, and dust collection tube 300 on the dust discharge plane do not overlap. Emptying the dust box 210 is most efficient when impurities accumulated in the dust box 210 are discharged in a direction perpendicular to the dust discharge plane.

[0121] In combination with the portable dust collecting device 10a and the portable dust collecting device 10b, the motor axis a of the motor 400 can be parallel or perpendicular to the dust box axis b of the dust box 210. In other embodiments, the motor axis a and the dust box axis b can also form an angle.

[0122] In order to connect the dust suction tube 300 with the housing 100 , referring to FIG. 1 , the portable dust suction device further includes a connector 700 disposed on the housing 100 . The connector 700 is used to connect the dust box 210 and the dust suction tube 300 .

[0123] In some embodiments, the connecting member 700 is a pipe fitting, one end of which is fixed on the outer wall of the shell 100, the pipe fitting is connected to the inner cavity of the shell 100, and the other end of the pipe fitting forms an insertion port, and the connecting end of the dust collection tube 300 is plugged into the pipe fitting through the insertion port.

[0124] It should be noted that the dust box 210 and the connector 700 can be directly connected or connected through an intermediate piece, which can be a connecting block. Further, a filter is provided at the connection point between the dust box 210 and the connector 700, and the filter is used to filter the airflow.

[0125] In order to enable the portable vacuum cleaner to carry the vacuum cleaner accessory 600 when moving and to prevent the vacuum cleaner accessory 600 from being lost due to separate storage, the portable vacuum cleaner also includes an accessory mounting portion 120 (see Figure 3). The accessory mounting portion 120 can be an independent component fixed on the shell 100, or it can be formed by a partial structure of the shell 100 that is recessed inward. The accessory mounting portion 120 is used to install at least one vacuum cleaner accessory 600.

[0126] Continuing with reference to Figure 1, the dust collection accessories 600 provided in the embodiment of the present application include a branch pipe dust collection head 610 and a T-shaped dust collection head 620. Among them, the branch pipe dust collection head 610 is in the shape of a "1", one end of which is continuously connected to the dust collection end of the dust collection tube 300, and the other end is formed with a dust collection port. Since the branch pipe dust collection head 610 is relatively slender, the size of the dust collection port is small, and the branch pipe dust collection head 610 can be inserted into the narrow gap to absorb foreign matter. The vertical section of the T-shaped dust collection head 620 is continuously connected to the dust collection end of the dust collection tube 300, and the horizontal section is formed with a larger dust collection port. The T-shaped dust collection head 620 is suitable for absorbing foreign matter on a plane.

[0127] Furthermore, the accessory mounting portion 120 is a groove formed on the shell 100. In order to install the branch pipe vacuum cleaner head 610 and the T-type vacuum cleaner head 620, the accessory mounting portion 120 includes a first mounting groove 121 and a second mounting groove 122. The first mounting groove 121 is roughly T-shaped and is used to accommodate the T-type vacuum cleaner head 620. The second mounting groove 122 is roughly "1"-shaped and is used to accommodate the branch pipe vacuum cleaner head 610.

[0128] It should be noted that the first mounting groove 121 and the second mounting groove 122 can be two independent grooves or two interconnected grooves. In order to save space, as shown in Figures 1 and 2, the first mounting groove 121 and the second mounting groove 122 partially overlap, and the second mounting groove 122 is located in front of the first mounting groove 121. When assembling the dust collection accessory 600, it is necessary to first place the T-shaped dust collection head 620 in the first mounting groove 121, and then place the branch tube dust collection head 610 in the second mounting groove 122; when disassembling the dust collection accessory 600, first disassemble the branch tube dust collection head 610, and then disassemble the T-shaped dust collection head 620. The disassembly direction of the branch tube dust collection head 610 and the T-shaped dust collection head 620 is parallel to the x-direction.

[0129] It should be further explained that after the branch tube vacuum head 610 and the T-shaped vacuum head 620 are installed in the corresponding mounting slots, the branch tube vacuum head 610 and the T-shaped vacuum head 620 can be completely sunken into the mounting slots, so that the vacuum accessory 600 is lower than the plane of the accessory mounting portion 120 formed by the housing 100. Of course, in other embodiments, the vacuum accessory 600 can also partially protrude from the plane of the accessory mounting portion 120 formed by the housing 100, or the vacuum accessory 600 can also be flush with the plane of the accessory mounting portion 120 formed by the housing 100.

[0130] In addition, after the battery pack 500 is mounted on the battery pack coupling portion 110, the surface of the battery pack 500 may be lower than the plane of the housing 100 forming the battery pack coupling portion 110. Alternatively, the surface of the battery pack 500 may be flush with the plane of the housing 100 forming the battery pack coupling portion 110. Alternatively, the surface of the battery pack 500 may be higher than the plane of the housing 100 forming the battery pack coupling portion 110.

[0131] To improve the portability of the portable vacuum cleaner, in some embodiments, the portable vacuum cleaner further includes a shoulder strap, which allows the entire portable vacuum cleaner to be hung on the user's body or on the device being used. The portable vacuum cleaner provided in the embodiments of the present application has high portability due to its small size, thinness, and shoulder strap.

[0132] As shown in Figure 17, in one embodiment, an accessory mounting portion is provided on the upper part of the portable vacuum cleaner 10b from the accommodating groove 130 to the interior of the shell, and the accessory mounting portion includes a brush mounting portion and a flat nozzle nozzle mounting portion, which are used to store the brush 131 and the flat nozzle nozzle 132 respectively. The stored brush 131 and the flat nozzle nozzle 132 do not affect the storage of the vacuum tube 300 in the accommodating groove 130. At the same time, the stored vacuum tube 300 serves to shield the accessories, which is beneficial to the appearance of the entire machine.

[0133] As shown in Figures 18 and 19, the portable vacuum cleaner can be used with a long vacuum hose 320, the total extended length of which is greater than or equal to 100 cm. A long rod mounting portion 340 is provided on the bottom surface of the housing 100 of the portable vacuum cleaner. The long vacuum hose 320 can be mounted to the housing 100 via the long rod mounting portion 340, allowing the portable vacuum cleaner to be mounted to the long vacuum hose 320 for use or to facilitate storage of the long vacuum hose 320. The long rod mounting portion 340 is composed of a sheath and screws. The shape of the sheath matches the outer contour of the vacuum hose 300 or the long vacuum hose 320. Two screw holes are punched into the surface of the sheath. The two screws are inserted into the two screw holes of the sheath, thereby securing the sheath to the housing 100. With this arrangement, the device body 101 of the portable vacuum cleaner 10b can be secured to an external vacuum hose or vacuum head via the long rod mounting portion 340 for use, as shown in Figure 19.

[0134] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
