[0067] like Figure 1 As shown, this embodiment provides a vacuum cleaner, which includes a handheld vacuum cleaner 1000 and a body, and the body includes a shaft 2000 and / or a vacuum head assembly. When the handheld vacuum cleaner 1000 is attached to the shaft 2000 and the vacuum head assembly, it is generally used to meet the needs of users to stand when operating the vacuum cleaner, without bending over, thereby reducing user fatigue; when the handheld vacuum cleaner 1000 is only attached to the shaft 2000, it is generally used to meet the needs of users to clean deep or high places that are difficult to reach; when the handheld vacuum cleaner 1000 is only attached to the vacuum head assembly, it is generally used for users to clean surfaces such as sofas and beds. The vacuum cleaner of the present invention includes but is not limited to the above usage scenarios. Among them, the vacuum cleaner includes but is not limited to cleaning equipment with a vacuuming function such as vacuum cleaners and floor scrubbers. In addition, the rod body 2000 and / or the vacuum head assembly can load or carry a dirt holding part, a liquid holding part, etc. (such as a detergent container, a clean water tank, a sewage tank, a dust cup, etc.) to meet the user's cleaning needs for cleaning the surface.

[0068] In this embodiment, the body includes a shaft 2000 and a dust collector head assembly (not shown). The bottom end of the shaft 2000 is connected to the dust collector head assembly, and the top end of the shaft 2000 is connected to the handheld dust collector 1000. When using the dust collector, the user can hold the handheld dust collector 1000 and push the dust collector head assembly to move across the surface to be cleaned to achieve cleaning.

[0069] Specifically, a dust suction port is provided on the bottom surface of the dust suction head assembly, a dust suction channel connected to the dust suction port is provided in the dust suction head assembly, the bottom end of the rod body 2000 is connected to the dust suction head assembly, and a main air duct connected to the dust suction channel is provided in the rod body 2000; the handheld dust suction device 1000 is provided on the rod body 2000, the handheld dust suction device 1000 includes a handheld main body 100 and a dust cup assembly 200, the dust cup assembly 200 is provided on the handheld main body 100, the handheld main body 100 includes a fan assembly 120 and a filter assembly, the dust cup assembly 200 is respectively connected to the main air duct and the fan assembly 120, and the filter assembly is provided between the dust cup assembly 200 and the fan assembly 120. When the fan assembly 120 is started, the dust on the surface to be cleaned is carried by the airflow and enters the dust cup assembly 200 through the dust suction port, the dust suction channel and the main air duct in sequence. The airflow inside the dust cup assembly 200 passes through the filter assembly, and the filtered airflow is discharged through the fan assembly 120. The filtered impurities gather in the dust cup assembly 200.

[0070] The handheld body 100 also includes an air duct assembly 130, and a handheld air duct is formed in the air duct assembly 130. One end of the air duct assembly 130 in the longitudinal direction is connected to the rod body 2000, and the other end is connected to the fan assembly 120. The handheld air duct is connected to the main air duct in the rod body 2000. The circumferential outer wall of the dust cup assembly 200 is connected to the circumferential outer wall of the air duct assembly 130, so that the dust cup assembly 200 and the air duct assembly 130 are arranged in parallel. With this arrangement, the dust cup assembly 200 and the air duct assembly 130 do not interfere with each other, avoid mutual influence, and ensure that there is enough space in the dust cup assembly 200 and the air duct assembly 130; the dust cup assembly 200 and the air duct assembly 130 are arranged in parallel, which can reduce the size of the handheld dust collection device 1000 along the length direction of the air duct assembly 130, making it easier for users to operate.

[0071] To facilitate cleaning high places or confined spaces, the handheld vacuum cleaner 1000 is detachably connected to the shaft 2000, allowing the vacuum cleaner to operate in both upright and handheld modes. When the vacuum cleaner is in the upright mode, the handheld vacuum cleaner 1000 is attached to the shaft 2000, allowing the user to move the vacuum head assembly over lower surfaces to be cleaned, such as the ground. When the handheld vacuum cleaner is detached from the shaft 2000, the user can use the handheld vacuum cleaner 1000 alone or with other accessories, allowing them to clean high or confined surfaces such as sofas, beds, and bookshelves.

[0072] like Figure 2 and Figure 3As shown, the dust cup assembly 200 includes a cup body 210 and a cup cover 220. The circumferential outer wall of the cup body 210 can be connected to the main air duct and is used to collect filtered dust and other garbage. One end of the cup body 210 forms a cup opening, and the cup cover 220 is movably connected to the cup body 210. The cup opening can be opened or covered by switching the position of the cup cover 220. The cup opening is opened when it is necessary to clean the garbage in the cup body 210, and the cup opening is covered to achieve a seal when vacuuming. In this embodiment, the interior of the cup body 210 is connected to the main air duct through a handheld air duct.

[0073] To facilitate the use of the handheld vacuum cleaner 1000 alone, the handheld main body 100 includes an air duct inlet 1311 and an air duct outlet 1312. The air duct inlet 1311 can serve as an air flow inlet, and can also be connected to the main air duct when the vacuum cleaner is in a vertical working state. The air duct outlet 1312 is connected to the cup body 210.

[0074] To facilitate users in cleaning the garbage in the cup body 210, the handheld vacuum cleaner 1000 also includes a lid opening component 300. The lid opening component 300 can drive the cup lid 220 to open the cup mouth to dump garbage, realize one-click dumping, reduce the cleaning difficulty of the user, and improve the user's experience.

[0075] Specifically, the lid opening assembly 300 includes a cup lid locking member 330, which can be detachably connected to the cup lid 220. The cup lid locking member 330 is movably provided on the cup body 210 so that the cup lid locking member 330 can switch between a locked position connected to the cup lid 220 and an unlocked position disengaged from the cup lid 220. When the cup lid locking member 330 is in the locked position, the cup lid locking member 330 is connected to the cup lid 220, so that the cup lid 220 covers the cup opening, and the dust cup assembly 200 can collect dust; when the cup lid locking member 330 is in the unlocked position, the cup lid locking member 330 is disengaged from the cup lid 220, and the cup lid 220 can open the cup opening to dump dust and other garbage.

[0076] Optionally, the cup cover 220 is rotatably connected to the cup body 210 , and the end of the cup cover 220 opposite to the position where it is rotatably connected to the cup body 210 can be connected to the cup cover locking piece 330 to improve the sealing effect of the cup cover 220 on the cup mouth.

[0077] The cup lid locking member 330 is provided with a first engaging portion 331, and the cup lid 220 is provided with a second engaging portion 221. The first engaging portion 331 and the second engaging portion 221 engage with each other to achieve a detachable connection. The cup lid 220 and the cup lid locking member 330 can be fixed by engaging, making it easy to connect or disconnect the two. In this embodiment, the second engaging portion 221 is a hook, and the first engaging portion 331 is a engaging protrusion. The hook can engage with the engaging protrusion to achieve the fixation of the cup lid 220 and the cup lid locking member 330.

[0078] Specifically, the cup lid locking piece 330 is arranged on the cup body 210, and a snap-fit protrusion is provided at one end of the cup lid locking piece 330 which is in the same direction as the opening of the cup body 210. When the cup lid 220 rotates toward the cup body 210, the snap-fit hook abuts against the snap-fit protrusion to prevent the snap-fit hook from disengaging from the snap-fit protrusion.

[0079] In other embodiments, the hook can be provided on the cup cover locking member 330 , and correspondingly, the snap-fit protrusion can be provided on the cup cover 220 , which can also achieve snap-fit fixation.

[0080] Optionally, a reset member is further provided between the cup cover 220 and the cup body 210, which elastically connects the cup body 210 and the cup cover 220. The reset member can drive the cup cover 220 to rotate in the direction of opening the cup mouth, so that after the cup cover locking member 330 moves to the unlocked position, the cup cover 220 can quickly open the cup mouth under the action of the reset member, making it convenient to dump dust.

[0081] Since the user holds the handheld vacuum cleaner 1000 to operate the shaft 2000 to drive the vacuum head assembly to move, there is a possibility that the cup cover locking part 330 will be accidentally triggered during use, causing the cup mouth to open and garbage to be dumped on the shaft 2000 and the surface to be cleaned, seriously affecting the user experience.

[0082] To solve the above problems, Figure 4 As shown, the handheld vacuum cleaner 1000 further includes a lid opening trigger 320 , which is movably disposed on the handheld body 100 . The lid opening trigger 320 is used to drive the cup lid locking member 330 to move to an unlocking position to open the cup mouth. When the handheld vacuum cleaner 1000 is assembled on the shaft 2000, the lid opening trigger 320 cooperates with the shaft 2000 to restrict the lid opening trigger 320 from moving relative to the handheld body 100, that is, the lid opening trigger 320 is locked with the handheld body 100, and the user cannot trigger the lid opening trigger 320, thereby fixing the cup lid locking member 330 in the locked position to prevent the cup lid 220 from being accidentally triggered to open; when the handheld vacuum cleaner 1000 is disengaged from the shaft 2000, the lid opening trigger 320 is disengaged from the shaft 2000, and the lid opening trigger 320 can be triggered and move relative to the handheld body 100 to drive the cup lid locking member 330 to move relative to the cup body 210, thereby being able to switch between the unlocked position and the locked position, meeting the needs of dumping dust and the needs of using the handheld vacuum cleaner 1000 alone.

[0083] In this embodiment, the handheld vacuum cleaner 1000 can only open the cup mouth to dump dust when it is removed from the rod body 2000, avoiding the user opening the cup mouth due to accidental triggering when in upright use, reducing the chance of accidental triggering and improving the user experience.

[0084] In this embodiment, when the handheld vacuum cleaner 1000 is mounted on the shaft 2000, a first gap is defined between the lid opening trigger 320 and the shaft 2000, and a second gap is defined between the lid opening trigger 320 and the cup lid locking member 330. In other words, when the handheld vacuum cleaner 1000 is mounted on the shaft 2000, the lid opening trigger 320 and the cup lid locking member 330 are not in contact, and the cup lid locking member 330 is not affected by the driving force of the lid opening trigger 320. This allows the cup lid locking member 330 to remain in its current position, preventing the cup lid locking member 330 from moving to the unlocked position. When the user accidentally triggers the lid opening assembly 300, even if the lid opening trigger 320 moves, before the lid opening trigger 320 contacts the cup lid locking member 330, the lid opening trigger 320 first contacts the shaft 2000, preventing the lid opening trigger 320 from moving further. This keeps the lid opening trigger 320 and the cup lid locking member 330 out of contact, thereby preventing the cup lid locking member 330 from being accidentally triggered. When the handheld vacuum cleaner 1000 is removed from the shaft 2000, the lid opening trigger 320 is disengaged from the shaft 2000, and the lid opening trigger 320 can move relative to the handheld body 100 without being restricted by the shaft 2000, so that the lid opening trigger 320 can contact the cup lid locking member 330, pushing the cup lid locking member 330 to the unlocked position. It should be noted that when the handheld vacuum cleaner 1000 is not attached to the rod body 2000 but to the vacuum head assembly, the lid opening trigger 320 abuts against the vacuum head assembly to restrict the movement of the lid opening trigger 320 to prevent the cup cover locking member 330 from being accidentally triggered.

[0085] To ensure that the lid-opening trigger 320 can first abut the shaft 2000 during its movement, thereby restricting its contact with the cup lid locking member 330, when the handheld vacuum cleaner 1000 is assembled on the shaft 2000, the lid-opening trigger 320 and the shaft 2000 are arranged in sequence along the length of the shaft 2000. In other words, the shaft 2000 and the cup lid locking member 330 are located on the same side of the lid-opening trigger 320, and the first spacing is smaller than the second spacing. This arrangement ensures that the lid-opening trigger 320 first abuts the shaft 2000 during its movement, thereby restricting its continued movement through the abutment between the lid-opening trigger 320 and the shaft 2000.

[0086] Specifically, if Figure 5As shown, the lid opening trigger 320 includes a first abutting end 3211 and a second abutting end 3221. When the handheld vacuum cleaner 1000 is mounted on the shaft 2000, the first abutting end 3211 is spaced apart from the shaft 2000 to form a first gap, and the second abutting end 3221 is spaced apart from the cup lid locking member 330 to form a second gap. When the user triggers the lid opening trigger 320, the first abutting end 3211 is first in abutment with the shaft 2000, preventing the lid opening trigger 320 from moving relative to the handheld body 100. This causes the second abutting end 3221 to remain spaced apart from the cup lid locking member 330, thereby preventing the cup lid locking member 330 from moving to the unlocked position.

[0087] In other embodiments, when the handheld vacuum cleaner 1000 is assembled on the shaft 2000, the first abutting end 3211 can contact the shaft 2000, that is, the first interval is zero, so that the cover opening assembly 300 in this state is in a locked state and cannot be triggered.

[0088] The lid opening trigger 320 constrains the lid opening trigger 320 to trigger the cup lid locking member 330 by abutting and cooperating with the first abutting end 3211 and the rod body 2000. The structure is simple and there is no need to change the structure of the rod body 2000. The first abutting end 3211 and the rod body 2000 are convenient to cooperate and disengage, which is conducive to reducing costs.

[0089] In this embodiment, the lid opening trigger 320 is slidably mounted on the handheld body 100, the cup lid locking member 330 is located on the sliding front side of the lid opening trigger 320, and the shaft 2000 is located on the sliding front side of the lid opening trigger 320. When the handheld vacuum cleaner 1000 is assembled on the shaft 2000, the lid opening trigger 320 slides, causing the first abutting end 3211 to approach the shaft 2000 while the second abutting end 3221 approaches the cup lid locking member 330. When the handheld vacuum cleaner 1000 is removed from the shaft 2000, the lid opening trigger 320 slides relative to the handheld body 100. Since the shaft 2000 is not located on the sliding front side of the first abutting end 3211, the first abutting end 3211 can continue to slide after sliding for a first interval, causing the second abutting end 3221 to gradually approach and abut the cup lid locking member 330, thereby pushing the cup lid locking member 330 to the unlocked position. During this process, the first abutting end 3211 does not contact the shaft 2000 , thereby avoiding structural interference.

[0090] In this embodiment, the cup lid locking member 330 is pushed to move by the second abutting end 3221, which has a simple structure and is conducive to reducing the space occupied by the mating ends of the cup lid locking member 330 and the lid opening trigger member 320, thereby avoiding affecting the size of the handheld vacuum cleaner 1000 and helping to reduce costs.

[0091] To ensure that when the lid opening trigger 320 is not triggered, the second abutting end 3221 can always be spaced apart from the cup lid locking member 330, the lid opening assembly 300 also includes a first elastic member 340, which elastically connects the handheld body 100 and the lid opening trigger 320. The elastic force exerted by the first elastic member 340 on the lid opening trigger 320 can drive the lid opening trigger 320 away from the cup lid locking member 330, so that the cup lid locking member 330 can be maintained in the locked position.

[0092] Optionally, the first elastic member 340 may be a spring, which has small size, light weight, and low cost, and is helpful in controlling the cost of the handheld vacuum cleaner 1000 .

[0093] Optionally, the first elastic member 340 may be sleeved on the first abutting end 3211 , so that the first elastic member 340 is guided by the first abutting end 3211 , thereby ensuring the accuracy of the elastic force provided by the first elastic member 340 .

[0094] To ensure that the cup lid locking member 330 can be stably maintained in the locked position, the lid opening assembly 300 also includes a second elastic member 350. The second elastic member 350 elastically connects the cup lid locking member 330 and the cup body 210. The elastic force exerted by the second elastic member 350 on the cup lid locking member 330 can drive the cup lid locking member 330 to move toward the locked position. The second elastic member 350 can maintain the locked position when the cup lid locking member 330 is not in contact with the lid opening trigger member 330, preventing the cup mouth from opening.

[0095] In this embodiment, Figure 6 As shown, the cup lid locking member 330 is rotatably mounted on the outer wall of the cup body 210. When the cup opening needs to be opened, the cup lid locking member 330 rotates, causing the engaging protrusion to rotate away from the hook, thereby avoiding the hook and disengaging the engaging protrusion from the hook, thereby unlocking the cup lid 220.

[0096] Specifically, two mounting parts 213 are protrudingly arranged opposite to each other on the outer wall of the cup body 210, and the cup lid locking piece 330 is located between the two mounting parts 213 and is rotatably connected to the two mounting parts 213 respectively. The mounting parts 213 can not only serve as a rotation support for the cup lid locking piece 330, but also limit the cup lid locking piece 330, limit the movement space of the cup lid locking piece 330, and avoid the position of the cup lid locking piece 330 from being offset.

[0097] Optionally, the same end of the two mounting portions 213 is connected by a connecting section 214 to form an inverted U-shape. Specifically, the end of the mounting portion 213 away from the cup opening is connected by the connecting section 214 to prevent the connecting section 214 from interfering with the cup lid locking piece 330 and the cup lid 220. By providing the connecting section 214, the gap between the cup lid locking piece 330 and the cup body 210 can be blocked, thereby achieving dustproof and aesthetic effects.

[0098] One end of the cup body 210 is connected to the fan assembly 120 , and a cup cover locking piece 330 is provided on the axial side wall of the other end of the cup body 210 so that the cup cover locking piece 330 and the cup cover 220 are closer to each other, making it easier for the two to fit together.

[0099] A dust cup inlet 211 is also provided on the circumferential side wall of the cup body 210 , and the dust cup inlet 211 is connected to the air duct outlet 1312 to facilitate air flow into the cup body 210 through the handheld air duct.

[0100] In this embodiment, the handheld body 100 further includes a handle 110, which is connected to the blower assembly 120. Specifically, the handle 110 is roughly U-shaped, with one end of the handle 110 connected to one axial end of the blower assembly 120, and the other end of the handle 110 connected to the other axial end of the blower assembly 120. The two ends of the handle 110 are arranged diagonally. This arrangement can reduce the impact of the handle 110 on the length and width dimensions of the handheld body 100, making it easier for the user to grip and operate.

[0101] The air duct assembly 130 includes an air duct inlet 1311 and an air duct outlet 1312. Both the air duct inlet 1311 and the air duct outlet 1312 are connected to the handheld air duct. The air duct inlet 1311 can serve as an air flow inlet, and the air duct outlet 1312 is connected to the dust cup assembly 200. The dust cup assembly 200 is connected to at least one of the air duct assembly 130 and the fan assembly 120, and the outlet end of the dust cup assembly 200 is connected to the fan inlet of the fan assembly 120. When using the handheld vacuum cleaner 1000, the user grasps the handle 110 and moves the handheld vacuum cleaner 1000 so that the air duct inlet 1311 is directed toward the surface to be cleaned to perform the vacuuming operation.

[0102] It can be understood that the fan assembly 120 is heavy, and by connecting the handle 110 to the fan assembly 120, the user can save more effort when using it.

[0103] Combine Figure 2 and Figure 3As shown, the air duct assembly 130 and the handle 110 are arranged radially along the fan assembly 120, and the fan assembly 120 is located between the air duct assembly 130 and the handle 110. When the user uses the handheld vacuum cleaner 1000, the user holds the handle 110 so that the handle 110 is located above the handheld vacuum cleaner 1000 and the air duct assembly 130 is located below the handheld vacuum cleaner 1000, which is more labor-saving to operate.

[0104] Optionally, one axial end of the fan assembly 120 forms a fan inlet, one axial end of the cup body 210 is connected to the fan inlet, and the other axial end of the cup body 210 is connected to the cup cover 220, that is, the cup body 210 is located on the front side of the fan inlet, and the axis of the cup body 210 is parallel to the axis of the fan assembly 120.

[0105] One end of the air duct assembly 130 is connected to the fan assembly 120, and the other end extends along the axial direction of the fan assembly 120 toward the front side of the fan inlet. The air duct assembly 130 is arranged in parallel with the dust cup assembly 200. This arrangement makes the layout of the air duct assembly 130 and the dust cup assembly 200 compact, and the space occupied by the air duct assembly 130 is roughly the same as the radial dimension of the fan assembly 120. Part of the length of the air duct assembly 130 coincides with the axial length of the dust cup assembly 200, which helps to reduce the length of the handheld dust collection device 1000 in the air duct assembly 130 direction, while ensuring that the air duct assembly 130 has a certain length.

[0106] like Figure 5 As shown, the cover opening trigger 320 includes a first portion 322, a third portion 323 and a second portion 321. The first portion 322 and the second portion 321 are respectively located on opposite sides of the third portion 323. Figure 5 and Figure 7 As shown, both the first portion 322 and the second portion 321 extend substantially along the length direction of the air duct assembly 130 , that is, along the second direction Y.

[0107] In this embodiment, if Figure 5 As shown, the first portion 322, the third portion 323, and the second portion 321 are connected in sequence. The orthographic projection of the lid opening trigger 320 along the first direction X is roughly an inverted U-shape, wherein the first direction X is perpendicular to the second direction Y and points from the air duct assembly 130 to the dust cup assembly 200. The first portion 322 is located between the air duct assembly 130 and the dust cup body 210. The end of the first portion 322 away from the third portion 323 is a second abutting end 3221, which is used to abut the cup lid locking member 330. The second portion 321 is located within the air duct assembly 130. The end of the second portion 321 away from the third portion 323 is a first abutting end 3211, which is used to abut the shaft 2000.

[0108] In this embodiment, the second portion 321 extends along the length of the air duct assembly 130, so that the end of the second portion 321 away from the third portion 323 can extend to the end of the air duct assembly 130 away from the fan assembly 120, thereby facilitating mating with the shaft 2000. A through hole is provided at the end of the air duct assembly 130 away from the fan assembly 120, and the end of the second portion 321 away from the third portion 323 can pass through the through hole, so that the first abutting end 3211 extends from the through hole and abuts against the shaft 2000.

[0109] To prevent the third portion 323 from interfering with the sliding of the cover opening trigger 320, Figure 8 As shown, the duct assembly 130 is provided with a sliding hole 1315, which extends along the length of the duct assembly 130, and the third portion 323 is slidably disposed in the sliding hole 1315. The provision of the sliding hole 1315 not only avoids structural interference, but also allows the third portion 323 to pass through the sliding hole 1315, thereby connecting the first portion 322 and the second portion 321 located on the inner and outer sides of the duct assembly 130.

[0110] Specifically, if Figure 7 and Figure 9 As shown, the air duct assembly 130 includes an air duct shell 131 and an outer cover 132 that is sleeved on the outside of the air duct shell 131. A handheld air duct is formed in the air duct shell 131, and a sliding hole 1315 is provided on the air duct shell 131. A cavity is enclosed between the air duct shell 131 and the outer cover 132. A notch is provided on the side of the outer cover 132 facing the cup body 210. Part of the air duct shell 131 is exposed through the notch, so that the sliding hole 1315 can be exposed outside the outer cover 132, so that part of the lid opening trigger 320 can extend through the sliding hole 1315 to the outside of the air duct assembly 130 to trigger the cup lid locking member 330. Specifically, one end of the third portion 323 connected to the first portion 322 extends out of the air duct assembly 130 through the sliding hole 1315, and the first portion 322 is exposed outside the air duct assembly 130, thereby making it possible for the first portion 322 to abut against the cup lid locking member 330 on the cup body 210.

[0111] Specifically, an air duct inlet 1311 is formed at one axial end of the air duct housing 131, and an air duct outlet 1312 is provided on the circumferential outer wall of the air duct housing 131 to facilitate communication between the air duct outlet 1312 and the dust cup inlet 211. In order to expose the air duct outlet 1312 to the air duct assembly 130, the air duct outlet 1312 is directly opposite the notch to prevent the air duct housing 131 from blocking the air duct outlet 1312.

[0112] It should be noted that after the dust cup assembly 200 is assembled with the handheld body 100, a slight gap may exist between the cup body 210 and the air duct assembly 130. It is only necessary to perform a sealing process between the air duct outlet 1312 and the dust cup inlet 211 to meet the suction requirements. To this end, an annular sealing ring is provided between the air duct outlet 1312 and the dust cup inlet 211 for sealing.

[0113] In this embodiment, the cavity formed between the duct housing 131 and the outer cover 132 is utilized to partially house the cover-opening trigger 320, thereby avoiding increasing the size of the outer cover 132 and maintaining the overall dimensions of the duct assembly 130. Specifically, the end of the third portion 323 connected to the second portion 321 extends through the sliding hole 1315 into the cavity formed by the duct housing 131 and the outer cover 132, and the second portion 321 is disposed in this cavity.

[0114] In this embodiment, the main air duct of the shaft 2000 extends axially and is offset within the shaft 2000 toward the cup body 210. Therefore, to ensure that the first abutting end 3211 of the second portion 321 avoids the main air duct of the shaft 2000 and reliably abuts against the end surface of the shaft 2000, the second portion 321 is protruded from the third portion 323 away from the cup body 210, and the first abutting end 3211 is offset relative to the second abutting end 3221 away from the cup body 210. To this end, the lid opening trigger 320 is configured to be substantially L-shaped in its orthographic projection along the second direction Y, with the second portion 321 located on one side of the L-shape and the first portion 322 and third portion 323 located on the other side of the L-shape. The cover-opening trigger member 320 is arranged to have a roughly U-shaped orthographic projection along the first direction X and / or a roughly L-shaped orthographic projection along the second direction Y, so that the cover-opening trigger member 320 minimizes the space it occupies on the handheld body 100 and the impact on structural changes to the handheld body 100.

[0115] In this embodiment, to further save space, the second portion 321 is configured as a flat plate-like structure extending along the length of the air duct assembly 130. This allows the second portion 321 to be attached to or positioned adjacent to the sidewall of the air duct housing 131, avoiding interference with the handheld air duct. Consequently, the handheld air duct formed within the air duct housing 131 only needs to make a small concession to accommodate the second portion 321 of the lid opening trigger 320, thereby reducing occupied space and minimizing the impact of the lid opening trigger 320 on the space of the air duct assembly 130. In this embodiment, the thickness of the flat plate-like structure of the second portion 321 ranges from 3 mm to 8 mm, preferably 5 mm. Typical non-limiting thicknesses of the second portion 321 are 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, or 8 mm.

[0116] In this embodiment, the second portion 321 is located within the cavity enclosed by the air duct housing 131 and the outer cover 132, while the first portion 322 extends into the space enclosed between the cup body 210 and the handheld body 100. This design is ingenious and requires few components. Furthermore, the first portion 322, third portion 323, and second portion 321 form a roughly L-shape in the second direction Y. The second portion 321 is a flat, plate-like structure that fits more closely to the handheld air duct, reducing space usage while ensuring stable triggering.

[0117] Optionally, the outer cover 132 includes a housing and an air duct cover 1322 disposed at an end of the housing facing away from the fan assembly 120. A central hole is disposed in the middle of the air duct cover 1322. An end of the air duct housing 131 facing away from the fan assembly 120 passes through the central hole and extends outside the outer cover 132, forming a docking end for docking with the shaft 2000. A through hole is provided in the air duct cover 1322 for extending the first abutting end 3211 of the second portion 321. The first abutting end 3211 of the second portion 321 is disposed within the cavity defined by the air duct housing 131 and the outer cover 132, and extends through the through hole to the outside of the air duct assembly 130 for abutting with the shaft 2000.

[0118] The top of the shaft 2000 includes a mating surface that abuts the air duct cover 1322. The top of the main air duct extends through the mating surface. When the handheld vacuum cleaner 1000 is assembled on the shaft 2000, the air duct cover 1322 abuts the mating surface, and the docking section of the air duct housing 131 is inserted into the main air duct, connecting the handheld air duct and the main air duct. The first abutting end 3211 abuts the mating surface.

[0119] In order to prevent the handheld vacuum cleaner 1000 from being positioned with the rod body 2000, a pit is provided on the mating surface, which cooperates with the first abutting end 3211. On the one hand, it can improve the positioning effect of the handheld vacuum cleaner 1000 and the rod body 2000, and on the other hand, it can play an anti-mistake role, ensuring that the handheld vacuum cleaner 1000 can be assembled with the rod body 2000 at a fixed angle.

[0120] In this embodiment, the cup cover locking piece 330 is located between the cup body 210 and the handheld main body 100. Through this arrangement, the cup cover locking piece 330 can be hidden and prevented from being exposed, thereby reducing the chance of the user accidentally touching the cup cover locking piece 330 and preventing the cup cover locking piece 330 from being violently damaged.

[0121] In order to avoid increasing the size or causing a gap between the cup body 210 and the handheld body 100 due to the provision of the cup cover locking member 330 between the cup body 210 and the handheld body 100, as shown in FIG. Figure 9 and Figure 10As shown, the side of the air duct assembly 130 facing the cup body 210 is concave to form an escape groove 1313, and the cup lid locking member 330 and the partial lid opening trigger member 320 are located in the escape groove 1313. By embedding the cup lid locking member 330 and the partial lid opening trigger member 320 in the escape groove 1313, it can ensure that the outer peripheral wall of the cup body 210 can fully contact and cooperate with the handheld main body 100, and greatly save installation space.

[0122] In this embodiment, the escape groove 1313 is disposed on the side of the air duct housing 131 of the air duct assembly 130 that faces the cup body 210. The escape groove 1313 is aligned with the notch in the outer cover 132, so that the escape groove 1313 can be exposed to the air duct assembly 130 through the notch. A sliding hole 1315 is defined in the sidewall of the escape groove 1313. The first portion 322 of the lid opening trigger 320 is located within the escape groove 1313, and a portion of the third portion 323 extends through the sliding hole 1315 into the escape groove 1313.

[0123] Specifically, the side wall of the air duct shell 131 facing the cup body 210 is recessed toward the inner side of the handheld air duct to form an avoidance groove 1313, and a sliding hole 1315 is opened on the side wall of the avoidance groove 1313 so that the third part 323 of the cover opening trigger 320 located on the outside of the air duct shell 131 can pass through the sliding hole 1315, thereby allowing the first part 322 to be located in the avoidance groove 1313.

[0124] Optionally, the air duct outlet 1312 is located at one end of the avoidance groove 1313 close to the fan assembly 120 .

[0125] In order to avoid affecting the size of the handheld air duct, such as Figure 10 As shown, along the length direction of the air duct assembly 130 ( Figure 10 In the second direction (Y), the projection of the air duct outlet 1312 and the projection of the avoidance groove 1313 at least partially overlap, thereby reducing the width of the gap, thereby facilitating a reduction in the size of the air duct assembly 130. The width of the gap corresponds to the third direction (Z), which is perpendicular to the extension direction of the air duct assembly 130.

[0126] Optionally, along the length direction of the air duct assembly 130 , the projection of the dust cup inlet 211 and the projection of the cup cover locking piece 330 at least partially overlap to reduce the width dimension of the gap, thereby facilitating reducing the size of the air duct assembly 130 .

[0127] In order to ensure the accuracy of the movement of the cover opening trigger member 320, a guide component is provided on the handheld body 100, and the guide component is slidably matched with the cover opening trigger member 320 to improve the sliding movement accuracy of the cover opening trigger member 320.

[0128] In this embodiment, Figure 9As shown, the guide assembly includes a guide member 133, which is provided with a guide groove, and the first portion 322 is slidably engaged within the guide groove. Since the first portion 322 is located between the cup body 210 and the air duct assembly 130, the guide member 133 is disposed within the avoidance groove 1313 to facilitate the engagement of the guide member 133 with the first portion 322. The guide groove is provided on the side of the guide member 133 facing away from the fan assembly 120.

[0129] In order to improve the stability and fit of the cup body 210 , the surface of the guide member 133 facing the cup body 210 can be a curved surface, which is matched with the outer peripheral surface of the cup body 210 to stably support the cup body 210 .

[0130] like Figure 11 As shown, the guide assembly also includes a guide column 1317 arranged on the outer wall of the air duct shell 131, and an elongated hole 3212 is provided on the second part 321. The guide column 1317 is slidably set in the elongated hole 3212. Through the cooperation between the guide column 1317 and the elongated hole 3212, a guide is provided for the movement of the second part 321.

[0131] Optionally, a plurality of guide posts 1317 may be provided, and each guide post 1317 corresponds to a long hole 3212 to enhance the guiding effect of the cover-opening trigger member 320 .

[0132] Optionally, the guide assembly further includes a stopper 1316 disposed on the inner wall of the air duct housing 131. The stopper 1316 is used to stop the lid opening trigger 320 in the direction from the second portion 321 to the first portion 322, thereby ensuring stability when a user operates the lid opening trigger 320. Specifically, the stopper 1316 is disposed on the side of the air duct housing 131 facing the cup body 210.

[0133] In order to facilitate the user to trigger the lid opening trigger 320, thereby opening the cup mouth, refer to Figure 4 and Figure 7 As shown, the lid opening assembly 300 further includes an operating member 310, which is movably connected to the handheld body 100, with at least a portion of the operating member 310 exposed outside the handheld body 100. The operating member 310 is connected to a lid opening trigger 320. The operating member 310 can move relative to the handheld body 100, thereby driving the cup lid locking member 330 to an unlocked position via the lid opening trigger 320. The provision of the operating member 310 makes it convenient for the user to trigger the cup lid locking member 330, thereby realizing the one-touch ash emptying function.

[0134] In this embodiment, the operating member 310 is a sliding member that slides along the length of the handheld body 100 and is fixedly connected to the lid opening trigger 320. The sliding of the sliding member causes the lid opening trigger 320 to slide relative to the handheld body 100, thereby driving the cup lid locking member 330 to rotate. Specifically, the outer cover 132 is provided with a mounting hole for the operating member 310 to pass through. One end of the operating member 310 is exposed outside the outer cover 132 for user operation, while the other end passes through the mounting hole in the outer cover 132 and connects to the second portion 321 of the lid opening trigger 320 to drive the lid opening trigger 320.

[0135] When the cup mouth needs to be opened, the handheld vacuum cleaner 1000 is removed from the rod body 2000, and then the sliding part is pushed, specifically the sliding part is pushed toward the air duct inlet 1311 of the air duct assembly 130. The sliding part will drive the lid opening trigger part 320 to overcome the elastic force of the first elastic part 340 and slide, so that the first abutting end 3211 moves in the direction of extending out of the air duct assembly 130; at the same time, the second abutting end 3221 contacts the cup cover locking part 330, and pushes the cup cover locking part 330 to overcome the elastic force of the second elastic part 350 and rotate to the unlocked position to open the cup mouth.

[0136] In other embodiments, the operating member 310 may be a pressing member that drives the cover opening trigger member 320 to slide. For example, the pressing member may be slidably disposed on the handheld body 100 along the radial direction of the handheld body 100, and the cover opening trigger member 320 may be driven by the pressing member.

[0137] To facilitate thorough cleaning of the dust cup assembly 200, the dust cup assembly 200 is detachably connected to the handheld body 100, allowing the user to remove the dust cup assembly 200 for thorough cleaning as needed. The cup cover locking member 330 is located on the dust cup assembly 200 and can be removed along with the dust cup assembly 200, ensuring that the cup opening is closed during the removal process to prevent dust from spilling out of the dust cup assembly 200.

[0138] In this embodiment, the dust cup assembly 200 is detachably connected to the fan assembly 120 and the air duct assembly 130 respectively to increase the connection position and improve the stability of the dust cup assembly 200 on the handheld body 100.

[0139] In this embodiment, the air duct assembly 130 is snap-fitted to the dust cup assembly 200, which is then plugged into the fan assembly 120. To install the dust cup assembly 200, first plug one end of the dust cup assembly 200 into the fan assembly 120, then press the dust cup assembly 200 toward the air duct assembly 130 to snap-fit the dust cup assembly 200 and the air duct assembly 130, completing the assembly. The removal process for the dust cup assembly 200 is the reverse of the above process and will not be described in detail here.

[0140] In this embodiment, Figure 6 As shown, the plug-in fit between the cup body 210 and the fan assembly 120 is configured as follows: a second plug-in portion 212 is provided on the inner wall of the cup body 210, and the fan assembly 120 includes a first plug-in portion, which is plug-fitted with the second plug-in portion 212. Optionally, the second plug-in portion 212 may be a plug-in slot, and the first plug-in portion may be a protruding plug-in protrusion, and the plug-in positioning of the dust cup assembly 200 and the fan assembly 120 is achieved by the cooperation between the plug-in protrusion and the disassembly slot.

[0141] In other embodiments, the first plug-in portion may be a plug-in groove, and correspondingly, the second plug-in portion 212 may be a plug-in protrusion, which may also achieve a plug-in positioning effect.

[0142] like Figure 12 and Figure 13 As shown, the dust cup assembly 200 further includes a dust cup fixing member 410, which is disposed on the cup body 210 and has a third clamping portion. The air duct assembly 130 is provided with a fourth clamping portion 1314, and the third clamping portion is engaged with the fourth clamping portion 1314. The third clamping portion and the fourth clamping portion 1314 can be any structure that can achieve a clamping fit, and this embodiment does not specifically limit this.

[0143] The plug-in fit formed by the first plug-in portion and the second plug-in portion 212 is located at the end of the cup body 210 axially close to the fan assembly 120, and the snap-fit fit formed by the third snap-fit portion and the fourth snap-fit portion 1314 is located at the end of the cup body 210 axially away from the fan assembly 120. At the same time, the plug-in fit and the snap-fit fit are located on the radially symmetrical side of the cup body 210. This arrangement allows the dust cup assembly 200 to be diagonally fixed on the handheld main body 100, making its installation more stable.

[0144] In order to improve the stability of the dust cup assembly 200 on the handheld body 100, the fourth clamping portion 1314 can be arranged in the avoidance groove 1313 of the air duct assembly 130 to ensure the contact area between the cup body 210 and the handheld body 100.

[0145] To facilitate the removal of the dust cup assembly 200 from the handheld main body 100, the dust cup fixing part 410 is movably provided on the cup body 210 to switch between a first position cooperating with the fourth clamping part 1314 and a second position disengaged from the fourth clamping part 1314; the dust cup assembly 200 also includes a dust cup picking and placing part 420, which is movably provided on the cup cover 220. The dust cup picking and placing part 420 can abut against the dust cup fixing part 410 to push the dust cup fixing part 410 to move to the second position.

[0146] By setting a dust cup picking and placing component 420 on the cup cover 220, the dust cup picking and placing component 420 can be operated to drive the dust cup fixing component 410 to switch to the second position, so that the third clamping part can be disengaged from the fourth clamping part 1314, and then the dust cup assembly 200 can be removed, which is convenient for operation.

[0147] In addition, the dust cup picking and placing component 420 is arranged on the cup cover 220, so that when the user holds the handheld vacuum cleaner 1000, the dust cup picking and placing component 420 is located below the dust cup assembly 200, which can reduce the chance of the user accidentally triggering the dust cup picking and placing component 420, thereby avoiding the dust cup assembly 200 from falling off during use and improving reliability.

[0148] Optionally, the dust cup assembly 200 further includes a third elastic member 440, which is elastically connected to the dust cup pick-up and placement member 420, and can achieve automatic reset of the dust cup pick-up and placement member 420, so as to avoid affecting the position of the dust cup fixing member 410 when the dust cup pick-up and placement member 420 is not triggered, thereby ensuring the clamping and matching effect of the third clamping portion and the fourth clamping portion 1314. The third elastic member 440 elastically connects the dust cup pick-up and placement member 420 and the cup cover 220 to drive the dust cup pick-up and placement member 420 to reset.

[0149] Optionally, the dust cup assembly 200 further includes a fourth elastic member 430, which is connected to the dust cup fixing member 410 and can realize automatic resetting of the dust cup fixing member 410, so that the dust cup fixing member 410 can be stabilized in the first position when no external force is applied, thereby ensuring the snap-fitting effect of the third clamping portion and the fourth clamping portion 1314. The fourth elastic member 430 elastically connects the dust cup fixing member 410 and the cup body 210 to drive the dust cup fixing member 410 to reset.

[0150] The third elastic member 440 and the fourth elastic member 430 may both be springs to reduce costs and occupy less space.

[0151] Optionally, the dust cup access member 420 is rotatably connected to the cup cover 220. The first end of the dust cup access member 420 is rotatably connected to the cup cover 220, and the second end of the dust cup access member 420 is used to abut the dust cup fixing member 410. The third elastic member 440 can be connected to the cup cover 220 and the second end of the dust cup access member 420. The user presses the second end of the dust cup access member 420 to drive the dust cup access member 420 to rotate, thereby pushing the dust cup fixing member 410 to switch to the second position.

[0152] It should be noted here that at least the second end of the dust cup placing and removing component 420 is exposed from the cup cover 220, so that the user can trigger the dust cup fixing component 410 by pressing the second end.

[0153] Optionally, the dust cup fixing member 410 is slidably connected to the cup body 210. When the user presses the second end, the second end rotates toward the inside of the cup body 210, pushing the dust cup fixing member 410 to slide toward the fan assembly 120, so that the third clamping portion and the fourth clamping portion 1314 are disengaged.

[0154] It should be noted here that the third clamping portion is located on the side of the fourth clamping portion 1314 close to the fan assembly 120, so that when the dust cup fixing part 410 slides toward the fan assembly 120, the third clamping portion can be disengaged from the fourth clamping portion 1314.

[0155] To save space, a clearance hole 332 is provided on the cup cover locking member 330. The dust cup fixing member 410 is located between the cup cover locking member 330 and the dust cup assembly 200. The third clamping portion is passed through the clearance hole 332 to cooperate with the fourth clamping portion 1314. This arrangement integrates the dust cup fixing member 410 and the cup cover locking member 330 in the same position, which has high integration, small space occupation, and convenient operation.

[0156] like Figure 14 As shown, optionally, a receiving groove 215 is recessed in the side wall of the cup body 210, and at least part of the dust cup fixing member 410 and at least part of the cup cover locking member 330 are located in the receiving groove 215. By providing the receiving groove 215, a smaller space in the cup body 210 can be occupied to install the cup cover locking member 330 and the dust cup fixing member 410, reducing the size of the cup cover locking member 330 and the dust cup fixing member 410 protruding from the cup body 210, thereby reducing the gap between the cup body 210 and the handheld main body 100, which is conducive to the compact fit of the cup body 210 and the handheld main body 100.

[0157] In this embodiment, the cup cover locking piece 330 is located on the side of the dust cup fixing piece 410 away from the cup body 210. In other words, the dust cup fixing piece 410 and the cup cover locking piece 330 are stacked and placed in the receiving groove 215, making the arrangement of the dust cup fixing piece 410 and the cup cover locking piece 330 more compact and taking up less space.

[0158] In addition, by cooperating with the avoidance groove 1313 set on the air duct assembly 130, the cup cover locking part 330 and the dust cup fixing part 410 are located in the space formed by the avoidance groove 1313 and the accommodating groove 215, which can ensure the close fit between the cup body 210 and the handheld main body 100, reduce the gap between the two, and help reduce the overall size of the handheld vacuum cleaner 1000.

[0159] In order to reduce the impact of the receiving groove 215 on the space inside the cup body 210, Figure 14 and Figure 15As shown, the accommodating groove 215 includes a first groove section 2151 and a second groove section 2152. The first groove section 2151 is located on the side of the second groove section 2152 axially away from the cup mouth of the cup body 210, and the depth of the first groove section 2151 is less than the depth of the second groove section 2152. Most of the dust cup fixing part 410 is located in the second groove section 2152. On the one hand, it provides a larger installation space for the dust cup fixing part 410, so that most of the structure of the dust cup fixing part 410 is located in the accommodating groove 215; on the other hand, space for accommodating the cup cover locking part 330 can be reserved on the side of the dust cup fixing part 410 away from the cup body 210. The depth of the first groove section 2151 is relatively shallow, and it only needs to be able to accommodate part of the cup cover locking part 330. When the cup cover locking part 330 is triggered by the lid opening trigger part 320, the space required for the end of the cup cover locking part 330 close to the fan assembly 120 to rotate toward the cup body 210 is provided. Most of the cup cover locking part 330 is located between the two mounting parts 213 and extends into the avoidance groove 1313 to cooperate with the second part 321.

[0160] In this embodiment, by setting the receiving groove 215 to a first groove section 2151 and a second groove section 2152 of different depths, the space inside the receiving groove 215 can be reasonably utilized, the size of the receiving groove 215 can be reduced, and the impact on the space inside the cup body 210 can be reduced.

[0161] In addition, if Figure 15 As shown, the side wall of the cup body 210 is recessed into the interior of the cup body 210 to form a receiving groove 215, and a corresponding raised portion is formed inside the cup body 210. The raised portion includes a transition slope 2153 and a curved surface 2154 connected to the transition slope. The transition slope 2153 is located on the side of the curved surface 2154 away from the cup mouth along the axial direction of the cup body 210. The transition slope 2153 corresponds to the first groove section 2151, and the curved surface 2154 corresponds to the second groove section 2152. When dumping dust, the transition slope 2153 is located above the curved surface 2154, which can transitionally connect the other inner walls of the cup body 210 and the raised portion, thereby preventing dust from sticking to the inner wall of the cup body 210 and improving the dust dumping effect.

[0162] The second groove section 2152 is an arc-shaped groove, and the inner wall of the cup body 210 forms an arc-shaped surface 2154 at the second groove section 2152 .

[0163] Specifically, combined Figure 12 and Figure 14 As shown, a first fixing post 216 is disposed within the receiving groove 215. The first fixing post 216 extends radially along the cup body 210, and one end of the second elastic member 350 is sleeved on the first fixing post 216. Mounting the second elastic member 350 via the first fixing post 216 positions and guides the second elastic member 350, thereby preventing the second elastic member 350 from shifting.

[0164] A second fixing post 217 is also disposed within the receiving groove 215. The second fixing post 217 extends axially along the cup body 210. One end of the fourth elastic member 430 is sleeved onto the second fixing post 217. Mounting the fourth elastic member 430 via the second fixing post 217 positions and guides the fourth elastic member 430, preventing it from shifting.

[0165] In this embodiment, the first fixing column 216 is located at the end of the accommodating groove axially away from the cup mouth along the cup body 210, and the second elastic member 350 is sleeved on the first fixing column 216 and abuts against the end of the cup lid locking member 330 away from the cup mouth. The elastic force applied by the second elastic member 350 to the cup lid locking member 330 can drive the end of the cup lid locking member 330 close to the cup mouth to rotate toward the cup lid 220, so that the cup body 210 and the cup lid 220 remain locked.

[0166] The second fixing post 217 is arranged perpendicular to the first fixing post 216, and the second fixing post 217 extends toward the cup opening. The fourth elastic member 430 is sleeved on the second fixing post 217. The elastic force exerted by the fourth elastic member 430 on the dust cup fixing member 410 can push the dust cup fixing member 410 to slide along the axial direction of the cup body 210 toward the cup opening, so that the dust cup fixing member 410 can be fixed to the air duct assembly 130.

[0167] In this embodiment, the dust cup fixing part 410 is located on the side of the cup cover locking part 330 facing the cup body 210, which facilitates the cooperation between the dust cup fixing part 410 and the fourth elastic part 430; the axial dimension of the dust cup fixing part 410 along the cup body 210 is smaller than the axial dimension of the accommodating groove 215 along the cup body 210, so that the first fixing column 216 is not blocked by the dust cup fixing part 410, which facilitates the cooperation between the second elastic part 350 and the cup cover locking part 330, the second elastic part 350 is located in the first groove section 2151, and the fourth elastic part 430 is located in the second groove section 2152.

[0168] In this embodiment, the cup lid locking piece 330 is rotatably connected to the mounting portion 213. The height dimension of the mounting portion 213 and the depth dimension of the accommodating groove 215 provide movable space for the cup lid locking piece 330, so that the depth dimension of the accommodating groove 215 can be smaller. The dimension of the accommodating groove 215 along the axial direction of the cup body 210 can only accommodate the cup lid locking piece 330, thereby reducing the size of the accommodating groove 215. It is only necessary to sacrifice a smaller space in the cup body 210 to form the accommodating groove 215 to accommodate the cup lid locking piece 330, the dust cup fixing piece 410, the second elastic piece 350 and the fourth elastic piece 430.

[0169] Optionally, a first guide member 218 is provided in the accommodating groove 215, and the first guide member 218 extends along the axial direction of the cup body 210. A sliding groove is provided on the side of the dust cup fixing member 410 facing the cup body 210, and the sliding groove slides with the first guide member 218 to guide the dust cup fixing member 410.

[0170] Specifically, two first guide members 218 are provided, and the first fixed column 216 and the second fixed column 217 are both located between the two first guide members 218. Through the cooperation between the first guide member 218 and the dust cup fixing member 410, on the one hand, the dust cup fixing member 410 is guided, and on the other hand, the dust cup fixing member 410 can be lifted up, so that a space for accommodating the first fixed column 216, the second fixed column 217 and the fourth elastic member 430 is formed between the dust cup fixing member 410 and the bottom surface of the accommodating groove 215.

[0171] Optionally, a second guide member 219 is further provided on the mounting portion 213 , and the second guide member 219 extends along the axial direction of the cup body 210 . The dust cup fixing member 410 is overlapped on the second guide member 219 to guide the dust cup fixing member 410 .

[0172] Optionally, two second guide members 219 are provided, and each mounting portion 213 is provided with a second guide member 219 , which is beneficial to improving the guiding effect and better supporting the dust cup fixing member 410 .

[0173] like Figure 16 As shown, in order to prevent the dust cup fixing part 410 from separating from the cup body 210, an end limit part 450 is also provided at the end of the accommodating groove 215 close to the cup mouth. The end limit part 450 can be fixedly connected to the first guide part 218 by fasteners such as screws. The end limit part 450 can abut against the dust cup fixing part 410 to limit the dust cup fixing part 410 from continuing to move toward the cup mouth.

[0174] In order to facilitate the cooperation between the dust cup fixing part 410 and the dust cup picking and placing part 420, a perforation 451 is provided on the end limit part 450. One end of the dust cup fixing part 410 can extend into the perforation 451 to facilitate the abutment by the dust cup picking and placing part 420, thereby pushing the dust cup fixing part 410 to overcome the elastic force of the fourth elastic part 430 and slide.

[0175] In this embodiment, when the dust cup assembly 200 is removed from the handheld main body 100, the avoidance groove 1313 of the air duct assembly 130 is used to accommodate the fourth clamping portion 1314 for fixing the cup body 210, the guide assembly for providing guidance for the lid opening trigger 320, and at least part of the cup lid locking member 330 and the dust cup fixing member 410. That is, by providing the concave avoidance groove 1313 on the side of the air duct assembly 130 facing the cup body 210, space is provided for the structures related to opening and fixing the dust cup assembly 200 without substantially affecting the handheld air duct, and the various structures are highly integrated with minimal modification to the original product.

[0176] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
