[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] Please refer to Figures 1-4 As shown, this application proposes a convenient vacuum cleaner 1, which allows users to effectively clean objects adhering to surfaces to be cleaned.

[0029] The portable vacuum cleaner 1 includes a dustbin module 10, a fan body module 40, a suction head module 30, and a handle module 60. The dustbin module 10 has a dust collection chamber (not shown), a fluid inlet 11a communicating with the dust collection chamber, and a fluid outlet 11c. The dustbin module 10 is configured to hold the object to be suctioned. The fan body module 40 is connected to the dustbin module 10 corresponding to the fluid outlet 11c, and the fan body module 40 is adapted to generate suction force. The suction head module 30 is connected to the dustbin module 10 corresponding to the fluid inlet 11a. The suction head module 30 is configured to guide the object to be suctioned into the dust collection chamber under the suction force of the fan body module 40. The handle module 60 is connected to the fan body module 40, and the handle module 60 and the suction head module 30 are respectively located on both sides of the central axis of the dustbin module 10.

[0030] The following combination Figures 1-9 The specific structure of the portable vacuum cleaner 1 will be described in detail.

[0031] like Figures 1-4 As shown, the portable vacuum cleaner 1 includes a dustbin module 10, a fan body module 40, a suction head module 30, and a handle module 60.

[0032] The dustbin module 10 serves as a waste collection station for the portable vacuum cleaner 1.

[0033] The dust collection module 10 has a dust collection chamber, which is the space inside the dust collection module 10 used to store the object to be adsorbed; the object to be adsorbed can be, but is not limited to, dust or paper scraps and other garbage.

[0034] The dust collection module 10 also has a fluid inlet 11a that communicates with the dust collection chamber. The fluid inlet 11a is the opening of the dust collection module 10 for allowing adsorbed substances such as dust or paper scraps to enter the dust collection chamber of the dust collection module 10. The specific shape of the fluid inlet 11a is not limited here, and designers can design it reasonably according to actual needs; for example, the cross-sectional shape of the fluid inlet 11a can be, but is not limited to, circular or rectangular.

[0035] The dust collection module 10 also has a fluid outlet 11c that communicates with the dust collection chamber. The fluid outlet 11c is the opening of the dust collection module 10 for allowing airflow to exit the dust collection chamber. The specific shape of the fluid outlet 11c is not limited here, and designers can design it reasonably according to actual needs; for example, the cross-sectional shape of the fluid outlet 11c can be, but is not limited to, circular or rectangular.

[0036] Specifically, the dust collection module 10 includes a collection body 11, which is the outer shell of the dust collection module 10. The collection body 11 has the aforementioned dust collection chamber, fluid inlet 11a, and fluid outlet 11c. The collection body 11 has a cylindrical structure, and the area enclosed by the inner cylindrical wall of the collection body 11 is the aforementioned dust collection chamber. The side wall of the collection body 11 has the aforementioned fluid inlet 11a, and the upper end face of the collection body 11 has the aforementioned fluid outlet 11c.

[0037] like Figures 1-4 As shown, the main fan module 40 serves as the air source for the portable vacuum cleaner 1. The main fan module 40 is suitable for generating suction force. Under the action of this suction force, the object to be suctioned will flow into the dust collection chamber of the dust collection module 10 through the fluid inlet 11a of the dust collection module 10 via the suction head module 30. The specific structure of the main fan module 40 will be described in detail below.

[0038] The main fan module 40 is positioned on the same side as the fluid outlet 11c of the dust bin module 10.

[0039] The main fan module 40 is connected to the dust collection module 10. The specific connection method between the main fan module 40 and the dust collection module 10 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the main fan module 40 can be detachably connected to the dust collection module 10 by at least one of the following methods: screw connection, snap connection, or plug connection. This facilitates the installation and disassembly of the main fan module 40 and the dust collection module 10, so as to facilitate the effective replacement of the damaged main fan module 40 or dust collection module 10 in the future.

[0040] The suction head module 30 serves as the adsorption structure of the portable vacuum cleaner 1. The suction head module 30 is configured to guide the object to be adsorbed into the dust collection chamber of the dust chamber module 10 under the suction force of the fan main body module 40. The specific structure of the suction head module 30 will be described in detail below.

[0041] The suction head module 30 is set to correspond to the fluid inlet 11a of the dust collection module 10, that is, the suction head module 30 is set on the same side as the fluid inlet 11a of the dust collection module 10.

[0042] The suction head module 30 is connected to the dustbin module 10. The specific connection method between the suction head module 30 and the dustbin module 10 is not limited here, and the designer can make a reasonable design according to the actual needs. For example, the suction head module 30 can be detachably connected to the dustbin module 10 by at least one of the following methods: screw connection, snap connection, or plug connection. This facilitates the installation and removal of the suction head module 30 and the dustbin module 10, so as to facilitate the effective replacement of the damaged suction head module 30 or dustbin module 10 in the future.

[0043] like Figures 1-4 As shown, the handle module 60 serves as the handle of the portable vacuum cleaner 1 for the user to hold; the specific structure of the handle module 60 will be described in detail below.

[0044] The handle module 60 is connected to the main fan module 40. The handle module 60 and the main fan module 40 can be a separate structure or an integrated structure. For example, when the handle module 60 and the main fan module 40 are separate structures, the handle module 60 can be detachably connected to the main fan module 40 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. For example, when the handle module 60 and the main fan module 40 are an integrated structure, the handle module 60 can be integrally formed with the main fan module 40 by injection molding or 3D printing.

[0045] The handle module 60 and the suction head module 30 are respectively located on both sides of the central axis of the dust collection module 10. Thus, when it is necessary to clean dust or paper scraps adhering to the surface to be cleaned, the user holds the handle module 60. At this time, the suction head module 30 is located on the side of the dust collection module 10 opposite to the handle module 60 and in front of the user, which is convenient for the user to operate and effectively clean dust or paper scraps adhering to the surface to be cleaned.

[0046] Based on the portable vacuum cleaner 1 in this embodiment, a dustbin module 10 is designed to store the object to be cleaned; a fan body module 40 is designed to generate suction force; a suction head module 30 is designed to guide the object to be cleaned, which is attached to the surface to be cleaned, into the dust collection chamber of the dustbin module 10 through the fluid inlet 11a under the suction force of the fan body module 40; and a handle module 60 is designed for the user to hold. By placing the suction head module 30 and the handle module 60 on both sides of the central axis of the dustbin module 10, when it is necessary to clean the object to be cleaned, the user holds the handle module 60, at which time the suction head module 30 is located on the side of the dustbin module 10 opposite to the handle module 60 and in front of the user, which facilitates user operation and allows for effective cleaning of the object to be cleaned.

[0047] like Figures 2-3 As shown, the suction head module 30 includes a suction head assembly 31 and a first electrical connector 33; the suction head assembly 31 is connected to the dust chamber module 10 corresponding to the fluid inlet 11a; the first end of the first electrical connector 33 is electrically connected to the suction head assembly 31, and the second end of the first electrical connector 33 is electrically connected to the electrical socket 41a of the fan body module 40; the suction head assembly 31 is configured to move when energized, so as to lift up the body to be adsorbed on the surface to be cleaned and adsorb it into the dust collection chamber.

[0048] The suction head assembly 31 serves as the suction head of the suction head module 30 and is used to adsorb objects to be adsorbed, such as dust or paper scraps adhering to the surface to be cleaned. Under the suction force of the main fan module 40 (specifically the main fan 46 described below), the objects are guided through the suction head assembly 31 into the dust collection chamber of the dust collection module 10. The specific structure of the suction head assembly 31 will be described in detail below.

[0049] The first electrical connector 33 serves as one of the electrical connection structures of the suction head module 30, and the first electrical connector 33 may include, but is not limited to, wires 331.

[0050] The second end of the first electrical connector 33 is electrically connected to the electrical socket 41a of the fan main module 40, which enables electrical conduction between the suction head assembly 31 and the electrical socket 41a of the fan main module 40. When the suction head assembly 31 is energized, it moves and can lift the object to be suctioned from the surface to be cleaned. Conversely, when the second end of the first electrical connector 33 is electrically disconnected from the electrical socket 41a of the fan main module 40, the electrical connection between the suction head assembly 31 and the electrical socket 41a of the fan main module 40 is broken, and the suction head assembly 31 cannot move when de-energized. This facilitates the electrical connection and disconnection between the suction head module 30 and the electrical socket 41a of the fan main module 40, and the operation is simple, convenient and quick.

[0051] Of course, the suction head module 30 also includes a magnetic port assembly 34; at this time, the first end of the first electrical connector 33 is electrically connected to the suction head assembly 31, and the second end of the first electrical connector 33 is positioned on the fan body module 40 through the magnetic port assembly 34 and achieves electrical connection with the electrical socket 41a of the fan body module 40. That is to say, the second end of the first electrical connector 33 is structurally fixed to the fan body module 40 by magnetic adsorption through the magnetic port assembly 34, and at the same time, the second end of the first electrical connector 33 is also electrically connected to the electrical socket 41a of the fan body module 40 through the magnetic port assembly 34. The specific structure of the magnetic port assembly 34 is not limited here, and designers can design it reasonably according to actual needs.

[0052] like Figure 5 As shown, the suction head assembly 31 includes a tube 311 extending along a first preset direction. The acute angle β between the first preset direction and the central axis of the dust collection module 10 is 10 degrees ≤ β ≤ 15 degrees. For example, the specific value of β can be, but is not limited to, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, or 15 degrees, etc.; preferably, β = 11 degrees. By reasonably designing the value of the angle β between the extension direction of the tube 311 and the central axis of the dust collection module 10, the suction objects such as dust or paper scraps sucked into the dust collection chamber are made to fit more closely to the angle required for pre-rotation, thereby improving the cleaning efficiency of the portable vacuum cleaner 1.

[0053] like Figure 5As shown, the suction head assembly 31 includes a tube 311 extending along a first preset direction; the handle module 60 includes a sub-shell 61 connected to the blower main body module 40, and the sub-shell 61 extends along a second preset direction; the obtuse angle between the first preset direction and the second preset direction is γ, and 10 degrees ≤ γ ≤ 30 degrees. For example, the specific value of γ can be, but is not limited to, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees, etc.; preferably, γ = 20 degrees. By reasonably designing the value of the angle γ between the extension direction of the tube 311 and the extension direction of the sub-shell 61, the suction port of the tube 311 is made to fit more closely to the surface to be cleaned when the user uses the portable vacuum cleaner 1, thereby improving the cleaning efficiency of the portable vacuum cleaner 1.

[0054] like Figure 6 As shown, the main fan module 40 includes a main housing 41 and a main fan 46 suitable for generating suction force; the main housing 41 is connected to the dust bin module 10 at the fluid outlet 11c; the main fan 46 is located inside the cavity of the main housing 41 and connected to the main housing 41. The handle module 60 includes a secondary housing 61 and a battery 62; the secondary housing 61 is connected to the main housing 41; the battery 62 is located inside the cavity of the secondary housing 61 and connected to the secondary housing 61, and the battery 62 is electrically connected to the main fan 46.

[0055] The main housing 41 serves as the outer shell of the main fan module 40 and is connected to the dust collection module 10. The specific connection method between the main housing 41 and the dust collection module 10 is not limited; designers can design it according to actual needs. For example, the main housing 41 can be detachably connected to the dust collection module 10 (specifically, the aforementioned collection body 11) by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. The main fan 46 serves as the air source for the main fan module 40 to generate the aforementioned suction force and is connected to the main housing 41. The specific connection method between the main fan 46 and the main housing 41 is not limited; designers can design it according to actual needs. For example, the main fan 46 can be detachably connected to the main housing 41 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the main fan 46 can also be non-detachably connected to the main housing 41 by adhesive bonding, but is not limited to this method. It should be noted that the main housing 41 has a cylindrical structure, and the area enclosed by the inner cylindrical wall of the main housing 41 is the cavity of the main housing 41. The side wall of the main housing 41 has the aforementioned electrical socket 41a.

[0056] The secondary housing 61 serves as the outer shell of the handle module 60 and is connected to the main housing 41. For example, when the handle module 60 and the main fan module 40 are separate structures, the secondary housing 61 can be detachably connected to the main housing 41 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. The battery 62 serves as the power source for the handle module 60, supplying power to the main fan 46 to generate the aforementioned suction force. The battery 62 is connected to the secondary housing 61. The specific model of the battery 62 is not limited here; designers can choose it reasonably according to actual needs. The specific connection method between the battery 62 and the secondary housing 61 is not limited here; designers can design it reasonably according to actual needs. For example, the battery 62 can be detachably connected to the secondary housing 61 by at least one of the following methods: snap-fit ​​connection or plug-in connection.

[0057] The main housing 41 is designed to support the main fan 46. The main fan 46 generates suction force, which guides dust or paper scraps adhering to the surface to be cleaned through the suction head module 30 to flow into the dust collection chamber of the dust chamber module 10 via the fluid inlet 11a. The secondary housing 61 is designed to support the battery 62 and is held by the user. The battery 62 powers the main fan 46 to generate the suction force. By placing the battery 62 inside the secondary housing 61, the internal space of the secondary housing 61 is utilized more efficiently, allowing the components to be arranged more compactly, thus reducing the overall size of the portable vacuum cleaner 1.

[0058] like Figure 6 As shown, the sub-shell 61 is integrally formed with the main shell 41, and the cavity of the sub-shell 61 is connected to the cavity of the main shell 41. The sub-shell 61 can be integrally formed with the main shell 41 by, but is not limited to, injection molding or 3D printing. This effectively reduces the processing difficulty between the sub-shell 61 and the main shell 41.

[0059] like Figure 6 As shown, the grip module 60 also includes a charging port 63 for electrical connection with an external power source. The charging port 63 is located at the end of the sub-housing 61 away from the main housing 41, and the charging port 63 is electrically connected to the battery 62.

[0060] The charging port 63 serves as the external charging port for the grip module 60. The charging port 63 connects to an external power source via a corresponding charging cable, enabling the external power source to charge the battery 62. The specific connection method between the charging port 63 and the sub-shell 61 is not limited here; designers can design it appropriately according to actual needs. For example, the charging port 63 can be detachably connected to the sub-shell 61 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the charging port 63 can also be non-detachably connected to the sub-shell 61 by adhesive bonding, but not limited to this method.

[0061] By designing the charging port 63, when the battery 62 has a low or zero charge, the user can connect the charging port 63 to an external power source using the corresponding charging cable. In this way, the external power source can charge the battery 62 in a timely manner to ensure that the battery 62 has a sufficient charge.

[0062] like Figures 7-9 As shown, the tube 311 has a cavity for the flow of the material to be adsorbed. The suction head assembly 31 also includes a drive member 312 and a fitting member 313; the drive member 312 is located in the cavity and connected to the tube 311, and is electrically connected to the first end of the first electrical connector 33; the fitting member 313 is located on the air inlet side of the tube 311 and extends at least partially out of the cavity, and is connected to the drive end of the drive member 312. The drive member 312 is configured to be energized to drive the fitting member 313 to move, so as to lift the material to be adsorbed adhering to the surface to be cleaned.

[0063] The tube 311, serving as the conduit for the suction head assembly 31, has a cavity through which the material to be absorbed flows; the specific structure of the tube 311 will be described in detail below. The drive unit 312, serving as the power source for the suction head assembly 311, drives the accessory 313 to move; the drive unit 312 may include, but is not limited to, a motor. The accessory 313, serving as an accessory for the suction head assembly 31, contacts the surface to be cleaned to lift up the material adhering to the surface.

[0064] By designing the pipe 311, a flow channel is provided for the object to be adsorbed, allowing it to be smoothly sucked into the dust collection chamber of the dust bin module 10. By designing the drive component 312 and the accessory component 313, the drive component 312 is electrically connected to the electrical socket 41a of the fan main module 40 via the first electrical connector 33. The drive component 312 is configured to drive the connected accessory component 313 to move when energized, so that the accessory component 313 contacts the surface to be cleaned to lift the adsorbed object adhering to the surface. In combination with the suction of the main fan 46 of the fan main module 40, the cleaning efficiency of the portable vacuum cleaner 1 can be effectively improved.

[0065] like Figures 7-9As shown, the tube 311 is telescopic; the suction head assembly 31 also includes a telescopic second electrical connector 314, the first end of the second electrical connector 314 being electrically connected to the drive member 312, and the second end of the second electrical connector 314 being electrically connected to the first end of the first electrical connector 33.

[0066] The tube 311 is extendable. When cleaning dust or paper scraps adhering to the surface, the tube 311 is extended, and the main fan 46 of the main fan module 40 is activated. Under the suction force of the main fan 46, the dust or paper scraps are smoothly sucked into the dust collection chamber of the dust chamber module 10 through the tube 311, achieving the purpose of cleaning. When cleaning is not required, the tube 311 is retracted, effectively reducing the space occupied by the suction head module 30, thereby reducing the overall space occupied by the portable vacuum cleaner 1 and facilitating user storage. Specifically, the tube 311 includes a first tube segment 311a and a second tube segment 311b, which are capable of relative extension and retraction, and are straight. Understandably, the first pipe segment 311a and the second pipe segment 311b undergo relative elongation, with the first pipe segment 311a extending out of the cavity of the second pipe segment 311b, at which point the fitting 311 is in an elongated state. Conversely, the first pipe segment 311a and the second pipe segment 311b undergo relative contraction, with the first pipe segment 311a retracting into the cavity of the second pipe segment 311b, at which point the fitting 311 is in a contracted state. By designing the first pipe segment 311a and the second pipe segment 311b as straight pipes, the structure is simple and easy to implement, and the smoothness of the relative elongation and contraction movements of the first pipe segment 311a and the second pipe segment 311b is also ensured. Of course, the fitting 311 may also include a third pipe segment 311c, where the first pipe segment 311a, the second pipe segment 311b, and the third pipe segment 311c can undergo relative elongation and contraction, and the third pipe segment 311c is also straight.

[0067] The second electrical connector 314 may include, but is not limited to, an elastic sleeve 314a and another wire 314b. The elastic sleeve 314a is fitted around the other wire 314b, thus providing good support for the other wire 314b and preventing the other wire 314b from getting tangled during the extension and retraction of the tube 311. By designing a retractable second electrical connector 314, the retractable second electrical connector 314 can move along with the tube 311 to ensure the effectiveness of the electrical connection between the drive member 312 and the first electrical connector 33.

[0068] like Figures 7-9As shown, it can be understood that the accessory 313, as an accessory of the suction head assembly 31, is used to contact the surface to be cleaned to lift up the adsorbent adhering to the surface to be cleaned; the specific form of the accessory 313 varies depending on the application scenario; the specific form of the accessory 313 may be, but is not limited to, one or more of the following embodiments.

[0069] In a first embodiment, the accessory 313 includes a brush head that is detachably connected to the drive end of the drive member 312; the drive member 312 is configured to be energized to drive the brush head to rotate so as to lift up the adsorbent adhering to the surface to be cleaned.

[0070] Here, the specific detachable connection method between the brush head and the drive end of the drive component 312 is not limited, and the designer can make reasonable designs according to actual needs; for example, the brush head can be connected to the drive end of the drive component 312 by at least one of the following methods: screw connection, snap connection or plug connection.

[0071] By designing the brush head, which is connected to the drive end of the drive unit 312, when it is necessary to clean dust or paper scraps adhering to the surface to be cleaned, the drive unit 312 is powered on to drive the brush head to rotate. The brush head contacts the surface to be cleaned, so that the dust or paper scraps adhering to the surface to be cleaned are lifted up by the sweeping action of the brush head. After being lifted up, the dust or paper scraps are smoothly sucked into the dust collection chamber of the dust bin module 10 through the pipe 311 by the suction action of the main fan 46 of the fan main module 40, so as to achieve the purpose of effective cleaning.

[0072] In the second embodiment, the accessory 313 includes a vibrating head, which is detachably connected to the drive end of the drive member 312; the drive member 312 is configured to be energized to drive the vibrating head to vibrate so as to lift up the adsorbent adhering to the surface to be cleaned.

[0073] Here, the specific detachable connection method between the vibrating head and the driving end of the driving component 312 is not limited, and the designer can make a reasonable design according to the actual needs; for example, the vibrating head can be connected to the driving end of the driving component 312 by at least one of the following methods: screw connection, snap connection or plug connection.

[0074] By designing a vibrating head, which is connected to the drive end of the drive unit 312, when it is necessary to clean dust or paper scraps adhering to the surface to be cleaned, the drive unit 312 is powered on to drive the vibrating head to vibrate. The vibrating head contacts the surface to be cleaned, so that the dust or paper scraps adhering to the surface to be cleaned are lifted up by the vibration of the vibrating head. After being lifted up, the dust or paper scraps are smoothly sucked into the dust collection chamber of the dust bin module 10 through the pipe 311 by the suction action of the main fan 46 of the fan main module 40, so as to achieve the purpose of effective cleaning.

[0075] It should be noted that the accessory 313 may include only the brush head, only the vibrating head, or both. When the accessory 313 includes both the brush head and the vibrating head, the user can connect either the brush head or the accessory to the drive end of the drive unit 312 as needed.

[0076] like Figures 7-9 As shown, the adsorption assembly also includes a head cover 315, which is installed on the air inlet side of the pipe 311 and extends at least partially into the cavity of the pipe 311. The drive unit 312 is connected to the pipe 311 via the head cover 315.

[0077] The head cover 315 serves as an intermediate connector between the drive component 312 and the pipe 311. The specific structure of the head cover 315 is not limited here, and designers can design it reasonably according to actual needs. It should be noted that the head cover 315 is designed on the air inlet side of the pipe 311. The head cover 315 has one or more openings that communicate with the cavity of the pipe 311. This allows dust or paper scraps adhering to the surface to be cleaned to pass smoothly through the openings of the head cover 315 and enter the cavity of the pipe 311 under the suction of the main fan 46 of the fan main module 40.

[0078] The specific connection method between the drive component 312 and the head sleeve 315 is not limited here; designers can design it reasonably according to actual needs. For example, the drive component 312 can be detachably connected to the head sleeve 315 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the drive component 312 can be non-detachably connected to the head sleeve 315 by adhesive bonding. Similarly, the specific connection method between the head sleeve 315 and the pipe fitting 311 is not limited here; designers can design it reasonably according to actual needs. For example, the head sleeve 315 can be detachably connected to the pipe fitting 311 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the head sleeve 315 can be non-detachably connected to the pipe fitting 311 by adhesive bonding.

[0079] By designing the head cover 315, the head cover 315 serves as an intermediate connector to position the drive component 312 on the pipe component 311, facilitating the assembly between the drive component 312 and the pipe component 311; on the other hand, the head cover 315 serves as a reinforcing rib to effectively strengthen the structural strength of the air inlet side of the pipe component 311.

[0080] like Figures 7-9 As shown, the suction head assembly 31 also includes a tail sleeve 316, which is installed on the air outlet side of the tube 311 and at least partially extends into the cavity of the tube 311. The specific connection method between the tail sleeve 316 and the tube 311 is not limited here; designers can design it reasonably according to actual needs. For example, the tail sleeve 316 can be detachably connected to the tube 311 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection. Alternatively, the tail sleeve 316 can be non-detachably connected to the tube 311 by adhesive bonding, but not limited to this method. By designing the tail sleeve 316, it acts as a reinforcing rib, effectively strengthening the structural strength of the air outlet side of the tube 311.

[0081] It should be noted that when the second electrical connector 314 includes the aforementioned elastic sleeve 314a, the tail end of the elastic sleeve 314a may be detachably connected to the tail sleeve 316 by at least one of the following methods: screwing, snap-fitting, or plugging, and the head end of the elastic sleeve 314a may be detachably connected to the head sleeve 315 by at least one of the following methods: screwing, snap-fitting, or plugging.
