[0070] Before any embodiments of the 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 above drawings.

[0071] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0072] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0073] In the present 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, direct connection refers to two parts or components being connected together without the need for an intermediary, and indirect connection refers to two parts or components being connected to at least one intermediary respectively, and the two parts or components being connected via the intermediary. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0074] In the present application, it will be understood by those of ordinary skill 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 tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. 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).

[0075] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0076] 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 another element "upper" or "lower", but also indirectly connected to another 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, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0077] The present application provides a portable dust suction device (10a, 10b), which can be used as a vehicle-mounted vacuum cleaner and in a vehicle to absorb dust and other foreign matter in the vehicle, thereby maintaining a clean environment in the vehicle. Of course, in addition to the vehicle, the portable dust suction device can also be carried with you, or used to clean the environment in a space such as an office at any time.

[0078] Figures 1 to 6 An embodiment of a portable dust collecting device 10a is disclosed. Figures 7 to 19 An embodiment of a portable vacuum cleaner 10b is disclosed. The common components of the portable vacuum cleaner 10a and the portable vacuum cleaner 10b are not distinguished in numbering and naming.

[0079] like Figures 1 to 18 As shown, the portable dust suction device (10a, 10b) mainly includes a housing 100, a battery pack joint 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 dust suction device. The battery pack joint 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 joint 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.

[0080] The battery pack joint 110 is used to install the battery pack 500. It should be noted that the battery pack joint 110 can be integrally formed with the housing 100 when the housing 100 is manufactured, or it can be an independent component and then fixed on the housing 100. 210 The dust box 210 is used to store dust and other foreign matter absorbed from the vehicle. The dust box 210 is connected to the housing 100 or installed inside the housing 100. The dust box 210 can also be a structure formed by the housing 100. One end of the dust suction tube 300 is a connection end, and the other end is a dust suction end. The connection end of the dust suction tube 300 is connected to the dust box 210, and the dust suction end of the dust suction tube 300 can be connected to at least the dust suction accessory 600. The motor 400 is used to generate negative pressure inside the portable dust suction device. 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, so that it is non-detachably arranged inside the housing 100.

[0081] The working principle of the portable vacuum cleaner is as follows: the motor 400 drives the blade 410 to rotate at high speed to generate negative pressure inside the housing 100. Under the action of negative pressure, foreign matter in the car is sucked into the vacuum tube 300 by the vacuum accessory 600, and the foreign matter enters the dust box 210 through the vacuum tube 300. The gas in the dust box under negative pressure is discharged from the motor side after passing through the filter element. If the foreign matter in the dust box 210 needs to be cleaned, the dust box 210 can be disassembled or opened to complete the disposal of the foreign matter, so that the foreign matter is out of the portable vacuum cleaner.

[0082] In order to facilitate the description of the structure of the portable vacuum cleaner, the front and rear directions of the portable vacuum cleaner are defined as Figure 1 The x direction in the figure defines the left and right directions of the portable vacuum cleaner as Figure 1 The y direction in the figure defines the up and down directions of the portable vacuum cleaner as Figure 1 The x, y and z directions are perpendicular to each other.

[0083] Combination Fig.14 and Fig.15, the shape of the portable vacuum cleaner is basically a rectangular parallelepiped, and the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 85mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 80mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 75mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 70mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 65mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 60mm. In some embodiments, the minimum of the length L, height H, and thickness T of the rectangular parallelepiped is less than or equal to 55mm. In other words, the minimum value of the maximum thickness of the portable vacuum cleaner in any direction is greater than or equal to 85mm, 80mm, 75mm, 70mm, 65mm or 60mm. In other words, in the case of a portable vacuum cleaner, it should be noted that the rectangular parallelepiped here refers to the state in which the vacuum tube 300 of the portable vacuum cleaner is stored close to the housing 100 and the dust cover 220 is closed (such as Figure 1 shown).

[0084] In some embodiments, the thickness of the portable vacuum cleaner along the x direction is less than or equal to 65 mm. This configuration makes the thickness of the portable vacuum cleaner smaller, so that the portable vacuum cleaner occupies less space. On the one hand, the portable vacuum cleaner can be stored in a storage bag behind a seat, in a storage space at a door, and in a storage box in the front row of a car, which is convenient for storage. On the other hand, one end of the portable vacuum cleaner can be placed in the user's thumb, which makes it easier for the user to hold the portable vacuum cleaner. It is more convenient for the user to operate in a relatively narrow environment such as in a car, thereby improving the user's experience.

[0085] 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.

[0086] 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. Such a configuration further reduces the volume of the portable vacuum cleaner, making the portable vacuum cleaner more compact.

[0087] 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. Such a configuration further reduces the volume of the portable vacuum cleaner, making the portable vacuum cleaner more compact.

[0088] 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.

[0089] 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.

[0090] like Figure 6 As shown, in some embodiments, the dust box 210 is cylindrical. Fig.13 As shown, in some other embodiments, the dust box 210 is in a cubic shape. In some other embodiments, part of the dust box 210 is a cylinder, and the remaining part extends from one side of the cylinder and is connected to the dust suction pipe 300, that is, the dust box 210 is a special-shaped box similar to a "tree branch".

[0091] In order to realize the rapid disassembly and assembly 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, and the first direction 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 along the up and down direction, left and right direction, or front and back direction, the battery pack 500 may also be plugged and unplugged in other directions, which is not limited here.

[0092] In some embodiments, the first projection of the battery pack 500 in the first plane perpendicular to the z direction (i.e., in the xoy plane) falls within the second projection of the portable vacuum cleaner in the first plane. In other words, after the battery pack 500 is installed to the battery pack coupling portion 110, it does not exceed the boundary of the housing 100 in the x direction.

[0093] In some embodiments, the portable vacuum cleaner can be powered by different battery packs, for example, the first battery pack or the second battery pack. That is, the battery pack coupling portion 110 can be installed with the first battery pack or the second battery pack. The electrical parameters of the first battery pack and the second battery pack are different. The electrical parameters here can be rated voltage, maximum output power, etc. In other embodiments, the volumes of the first battery pack and the second battery pack may also be different.

[0094] 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. Exemplarily, the output power of the first battery pack may 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. In other words, 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 may specifically be 80W, 100W, 110W, 120W, 130W, 140W, or 150W.

[0095] In some specific embodiments, the rated voltage of the first battery pack and the rated voltage of the second battery pack may be any voltage value between 12 V and 40 V. For example, the rated voltage of the first battery pack may 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 may be 8 V, 12 V, 16 V, 20 V, 24 V, 30 V, 36 V, 40 V, etc.

[0096] In order to facilitate the user to hold the portable vacuum cleaner, a portion of the structure on the shell 100 is recessed inward or protruded outward to form a gripping portion 140 for the user to hold.

[0097] 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.

[0098] exist Figures 7 to 14 In the technical solution shown, the dust suction pipe 300 has one end connected to the housing 100, namely the connecting piece 700; the dust suction pipe 300 also includes the other end opposite to the connecting piece 700, namely the air inlet 161 on the dust suction pipe 300 for allowing external airflow to flow into the dust suction pipe 300. The opening formed at the connection between the connecting piece 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. It can also be said that the dust inlet 170 is provided at the connection between the dust suction pipe 300 and the dust collecting device 200, and allows airflow to flow from the dust suction pipe 300 into the dust collecting device 200.

[0099] The housing 100 has a dust cover 220 facing 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, so that the dust outlet is opened or closed.

[0100] A filter element 240 is also provided in the dust box 210, and the filter element 240 can filter 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, and 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.

[0101] In order to facilitate the dumping of foreign objects 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 key 230. By operating the first key 230, the dust cover 220 can be moved to open the dust discharge port 250. The operation here can be pressing, touching, pushing, etc. As for how to operate the first key 250 to drive the dust box cover to move, it is a prior art and will not be described in detail here. In one embodiment, the dust collecting device 200 of the portable dust suction device has a one-button pop-up function, that is, the dust cover 210 can be quickly popped out by operating the first key 230. When using, the user can invert the portable dust suction device and aim it at the trash can, and operate the first key 230 to achieve rapid discharge of dust.

[0102] In one embodiment, the portable vacuum cleaner further comprises a second button 260, and the dust box 210 and / or the filter element 240 in the dust box 210 can be unloaded by operating the second button 260. The operation here can be rotation, pressing or touching. Fig. 9 As shown, the filter element 240 is disassembled by rotating the second key 260. As for how to operate the second key 260 to unload the dust box 210 or the filter element 240, it is a prior art and will not be described in detail here. In addition to the cylindrical or conical shape disclosed in this application, the filter element 240 can also be a cubic shape, which is not limited here.

[0103] 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.

[0104] like Figure 6 As shown, 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 on the same line. Figure 6 As shown, the battery pack 500 is arranged on one side of the motor 400 and the dust box 210, and the dust collection accessory 600 is arranged on the other side of the battery pack 500, that is, the dust collection accessory 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 the arrangement of the components in the portable dust collection device reasonable, and it is easier to realize the miniaturization of the portable dust collection device.

[0105] In some embodiments, the projections of the motor 400, the dust box 210, the dust suction tube 300, and the battery pack 500 in a vertical plane perpendicular to the front-to-back direction (i.e., the yoz plane) do not overlap. In other words, the above components are basically laid flat inside and outside the housing 100, thereby ensuring that the thickness of the dust suction device is relatively small.

[0106] See also Figure 6 and Fig.17 The housing 100 is provided with an exhaust port 150, and the exhaust port 150 is provided near the motor 400. In some embodiments, the exhaust port 150 is provided directly above the motor 400. In some other embodiments, a part of the structure of the housing 100 is recessed inward to form a receiving groove 130, and the receiving groove 130 is used to accommodate the dust suction tube 300, and the exhaust port 150 is provided in the receiving groove 130.

[0107] Below Figures 7 to 13 The disclosed portable dust collecting device 10b is Figures 1 to 6 The different technical solutions in the disclosed portable dust collecting device 10a are further described.

[0108] The portable dust suction device 10b is formed by connecting a device body 101 and a dust suction 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, and the storage space of the shell 100 at least accommodates the motor 400 and the dust box 210. At least the shell 100 opposite to the dust box 210 in the front and rear directions is set as a transparent part. The battery combination 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 dust suction tube 300 can be stored in the device body 101. The mass of the device body 101 is less than or equal to 3kg. In some embodiments, the mass of the device body 101 can be 2.8kg, 2.5kg, 2.2kg, 2kg, 1.7kg or 1.5kg.

[0109] 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 flows into the dust guide channel 270 after being filtered by the filter element 240, and then flows to the motor 400 through the dust guide channel 270.

[0110] A dust guide channel 270 is provided in the accommodation space formed by the contact between the dust box 210 and the housing 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 inside 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 terminal end is connected to the airflow connecting pipe 420 between the motor 400 and the housing 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 then flows out from the exhaust port 150 (see FIG. Figure 6 , Fig.13 and Fig.17 )discharge.

[0111] 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, and 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.

[0112] When the dust cover 220 is opened, the user points the front side of the portable vacuum cleaner 10b at the trash can, and relies on the inertia and gravity of the dust cover 220 to pour out the dust and impurities in the dust box 210. The plane where the dust discharge port 250 is located is perpendicular to the front-to-back direction, and the direction in which the dust discharge port 250 discharges dust is basically from the back side of the portable vacuum cleaner 10b to the front side. In other words, the user points the portable vacuum cleaner 10b at the trash can, and relies on the inertia and gravity of the dust cover 220 to pour out the dust and impurities in the dust box 210. Fig. 9 In the state shown, aim at the trash can and press the first button 230 at the same time, so that the dust can be poured out without any trouble.

[0113] 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 may be 3600 square millimeters, 3800 square millimeters, 4200 square millimeters, 4500 square millimeters, 5000 square millimeters, etc. The value of 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 value of 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 in 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. Such a setting can make the dust removal efficiency of the dust box 210 higher.

[0114] In some common dust collecting devices, the arrangement structure of the dust box 210 and the motor 400 is similar to Figure 7 The arrangement in the embodiment is that the motor 400 and the dust box 21 are arranged in the shape of a "1" and are directly connected, and the airflow flows directly from the dust box 21 into 400. Therefore, if the existing portable vacuum cleaner wants to be sufficiently "thin", the area of ​​the dust outlet 250 will also be affected by the thickness of the whole machine, making it difficult to enlarge the dust outlet 250. This solution changes the dust box 210 and the motor 400 from overlapping up and down to "laying" on a plane perpendicular to the up and down direction, thereby meeting the user's needs for a large dust outlet and a thin whole machine.

[0115] 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.

[0116] 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, which 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.

[0117] The portable dust suction device 10b also includes a switch device 800 for the user to control the working state of the motor 400, and the switch device includes a first operating member 810 and a second operating member 820. The first operating member 810 is used to turn on or off the operation of the motor 400 of the portable dust suction device 10b, and the second operating member 820 is configured to adjust the dust suction capacity. When the user presses the first operating member 810, the portable dust suction device 10b works at a gear position with maximum dust suction capacity, and when the user presses the second operating member 820, the dust suction capacity is reduced. In another embodiment, when the user presses the first operating member 810, the portable dust suction device 10b works at a gear position with moderate dust suction capacity, and when the user presses the second operating member 820, the dust suction capacity is adjusted to the maximum.

[0118] In some embodiments, the vent 150 can be connected to an inflatable accessory 310 (see Fig.18 ), to inflate the external device. Optionally, the inflatable accessory is an inflatable nozzle, and the external device can be a swimming ring, a balloon, etc.

[0119] In some embodiments, the housing 100 is in a cubic shape, the receiving groove 130 is a U-shaped groove opened on multiple sidewalls of the housing 100, and the dust suction tube 300 is wound around the housing 100 and is roughly bent in a U-shape. It should be noted that if the cubic boundary of the housing 100 is provided with a chamfer or fillet with a larger radius, but still presents the "flat" structure of the present application, it should also fall within the protection scope of the present application.

[0120] In some embodiments, the dust suction tube 300 is fixed in the receiving groove 130 by magnetic attraction; in some other embodiments, the dust suction tube 300 is buckled in the receiving groove 130 by snap-fitting.

[0121] 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.

[0122] In some embodiments, the vacuum tube 300 is a telescopic tube, and the telescopic length of the vacuum tube 300 is greater than or equal to 40 cm and less than or equal to 150 cm. By setting the vacuum tube 300 as a telescopic tube, after the vacuum tube 300 is taken out of the receiving groove 130, all parts of the portable vacuum device except the vacuum tube 300 and the vacuum accessory 600 can remain stationary, and only the telescopicity of the vacuum tube 300 can move the vacuum accessory 600 to the surface or gap to be vacuumed for vacuuming. This can avoid the user holding the shell 100, further improving the user experience. Fig.16As shown, in order to facilitate the placement of the portable vacuum cleaner and improve the stability of the portable vacuum cleaner in the vehicle, in some embodiments, the portable vacuum cleaner further includes a clamp 330, which can clamp and fix the portable vacuum cleaner on an external mechanism. The external mechanism here specifically refers to a component in the vehicle, such as a storage bag on a seat, a storage space on a door, etc. Clamping and fixing the portable vacuum cleaner on an external mechanism can prevent the portable vacuum cleaner from being damaged due to shaking during the movement of the vehicle.

[0123] In some embodiments, the clamp 330 is fixedly connected to the outer wall of the shell 100 or detachably connected to the outer wall 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 set on the shell 100, the clamp can also be set 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 clamps 330 can be set to one or more according to needs. Fig.16 The number of clamping members 330 shown is two. Fig. 9 As shown, two mounting holes 331 are provided on the housing 100 , and screws pass through the clamping member 330 and are screwed into the mounting holes 331 to fix the clamping member 330 and the housing 100 .

[0124] In some embodiments, the clamp 330 is a metal clip or a plastic clip.

[0125] In some embodiments, the clamp 330 is a spring clamp or a duckbill clamp.

[0126] In some embodiments, in order to improve the stability of the portable vacuum cleaner when mounted on an external mechanism, the clamp 330 is disposed at the center of gravity of the portable vacuum cleaner, or above the center of gravity of the portable vacuum cleaner.

[0127] 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 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.

[0128] In order to enable the portable vacuum cleaner to be stably placed on the external placement platform, the portable vacuum cleaner has at least one placement surface 180 (see Figure 2 and Figure 5 ), the portable vacuum cleaner can be stably placed on an external placement platform in a face-down manner. The external placement platform here can be a console, seat or storage box in the car.

[0129] The plugging and unplugging direction of the battery pack 500 is along the up-down direction of the portable vacuum cleaner. In some embodiments, the plugging and unplugging direction of the battery pack 500 can be any direction within the vertical plane (i.e., the yoz plane) formed by the up-down direction and the left-right direction of the portable vacuum cleaner. The advantage of such a setting is that when replacing battery packs 500 of 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 the stability when placed.

[0130] In order to improve 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, the second placement surface is formed on the housing 100, and the second placement surface 182 and the first placement surface 181 are parallel or perpendicular to each other. Of course, in other embodiments, the placement surfaces can be further increased according to demand, for example, the portable vacuum cleaner in the storage state is designed to be a cube, so that the portable vacuum cleaner has six placement surfaces.

[0131] 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 at the front side of the portable vacuum cleaner 10b, the placement surface 180 is the rear side surface of the housing 100 of the portable vacuum cleaner 10b.

[0132] The motor axis a of the motor 400 is substantially perpendicular to the front-to-back direction of the portable dust collecting device 10b, and the motor axis a of the motor 400 is also substantially perpendicular to the left-to-right direction of the portable dust collecting device 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 extension direction of the dust box axis b is the depth direction of the dust box 210. In this embodiment, the direction of the dust box axis b is also 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 where the outer surface of the dust cover 220 is located do not overlap. The projections of the motor 400 and the battery pack 500 on the plane where the outer surface of the dust cover 220 is located do not overlap, the projections of the dust box 210 and the battery pack 500 on the plane where the outer surface of the dust cover 220 is located do not overlap, the projections of the motor 400, the dust box 210 and the battery pack 500 on the plane where the outer surface of the dust cover 220 is located do not overlap, and the projections of the motor 400, the dust box 210, the battery pack 500 and the dust suction pipe 300 on the plane where the outer surface of the dust cover 220 is located do not overlap. The plane where the outer surface of the dust cover 220 is located (that is, 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, and the dust discharge plane is parallel to the outer surface of the dust cover. In other words, the projections of at least two of the motor 400, the dust box 210, the battery pack 500 and the dust suction pipe 300 on the dust discharge plane do not overlap. When the impurities accumulated in the dust box 210 are poured out in a direction perpendicular to the dust discharge plane, the efficiency of emptying the dust box 210 is the highest.

[0133] In combination with the portable dust suction device 10a and the portable dust suction device 10b, the motor axis a of the motor 400 may 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 may also form an angle.

[0134] In order to realize the connection between the dust suction pipe 300 and the housing 100, continue to refer to Figure 1 As shown, the portable dust suction device further includes a connecting member 700 disposed on the housing 100 , and the connecting member 700 is used to connect the dust box 210 and the dust suction pipe 300 .

[0135] 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 a plug interface, and the connecting end of the dust collection tube 300 is plugged into the pipe fitting through the plug interface.

[0136] It should be noted that the dust box 210 and the connector 700 can be directly connected or connected through an intermediate piece, and the intermediate piece can be a connecting block. Further, a filter screen is provided at the connection point between the dust box 210 and the connector 700, and the filter screen is used to filter the airflow.

[0137] In order to enable the portable vacuum cleaner to carry the vacuum cleaner accessory 600 and avoid the vacuum cleaner accessory 600 from being lost due to being stored alone, the portable vacuum cleaner further includes an accessory mounting portion 120 (see FIG. 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 being recessed inwardly, and the accessory mounting portion 120 is used to install at least one dust collection accessory 600.

[0138] Continue to refer to Figure 1 As shown, the dust collection accessory 600 provided in the embodiment of the present application includes a branch tube dust collection head 610 and a T-shaped dust collection head 620. Among them, the branch tube dust collection head 610 is in the shape of a "1", one end of which can be 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 tube dust collection head 610 is relatively slender, the size of the dust collection port is small, and the branch tube 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.

[0139] Furthermore, the accessory mounting portion 120 is a groove formed on the shell 100. In order to install the branch pipe vacuum head 610 and the T-type vacuum 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 head 620. The second mounting groove 122 is roughly "1"-shaped and is used to accommodate the branch pipe vacuum head 610.

[0140] It should be noted that the first installation groove 121 and the second installation groove 122 can be two grooves independent of each other, or two grooves connected to each other. Figure 1 and Figure 2 As shown, the first installation slot 121 and the second installation slot 122 partially overlap, and the second installation slot 122 is located in front of the first installation slot 121. When assembling the dust collection accessory 600, it is necessary to first place the T-shaped dust collection head 620 in the first installation slot 121, and then place the branch dust collection head 610 in the second installation slot 122; when disassembling the dust collection accessory 600, first disassemble the branch dust collection head 610, and then disassemble the T-shaped dust collection head 620. The disassembly direction of the branch dust collection head 610 and the T-shaped dust collection head 620 is parallel to the x direction.

[0141] It should be further explained that after the branch tube dust collector head 610 and the T-shaped dust collector head 620 are installed in the corresponding installation grooves, the branch tube dust collector head 610 and the T-shaped dust collector head 620 can be completely sunken into the installation grooves, so that the dust collection accessory 600 is lower than the plane of the accessory installation portion 120 formed by the shell 100. Of course, in other embodiments, the dust collection accessory 600 can also partially protrude from the plane of the accessory installation portion 120 formed by the shell 100, or the dust collection accessory 600 can also be flush with the plane of the accessory installation portion 120 formed by the shell 100.

[0142] 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 is flush with the plane of the housing 100 forming the battery pack coupling portion 110. Alternatively, the surface of the battery pack 500 is higher than the plane of the housing 100 forming the battery pack coupling portion 110.

[0143] In order to improve the portability of the portable vacuum cleaner, in some embodiments, the portable vacuum cleaner further comprises a shoulder strap, through which the entire portable vacuum cleaner can be hung on the user's body or on the device using the portable vacuum cleaner. The portable vacuum cleaner provided in the embodiment of the present application has high portability due to its small size, small thickness and shoulder strap.

[0144] like Fig.17 As shown, in one embodiment, an accessory mounting portion is provided on the upper portion 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 suction head mounting portion, which are used to store the brush 131 and the flat nozzle suction head 132 respectively. The stored brush 131 and the flat nozzle suction head 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 has a shielding effect on the accessories, which is beneficial to the aesthetics of the whole machine.

[0145] like Fig.18 and Fig.19 As shown, the portable vacuum cleaner can be used in conjunction with a long vacuum tube 320, and the total extended length of the long vacuum tube 320 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, and the long vacuum tube 320 can be mounted to 100 through the long rod mounting portion 340, so that the portable vacuum cleaner can be mounted to the long vacuum tube 320 for use, or the long vacuum tube 320 can be stored for convenience. The long rod mounting portion 340 is composed of a sheath and a screw, and the shape of the sheath matches the outer contour of the vacuum tube 300 or the long vacuum tube 320. Two screw holes are punched on the surface of the sheath, and the two screws are respectively inserted into the two screw holes of the sheath, thereby fixing the sheath and the housing 100. With such a configuration, the device body 101 of the portable vacuum cleaner 10b can be fixed to an external vacuum tube or vacuum head through the long rod mounting portion 340 for use, such as Fig.19 shown.

[0146] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
