Detailed Implementation

[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] Combination Figures 1 to 7According to an embodiment of the present invention, a dust cup assembly 100 includes a cup body 10 and a cover 20. The cup body 10 has a dust outlet 11 through which the material inside the cup body 10 can be discharged to the outside. The cover 20 is disposed at the dust outlet 11 of the cup body 10 and is used to open and close the dust outlet 11, having an open position and a closed position. When the cover 20 opens the dust outlet 11, the material inside the cup body 10 can be discharged to the outside through the dust outlet 11. When the cover 20 closes the dust outlet 11, the material is temporarily stored inside the cup body 10 to prevent leakage to the outside. The cover 20 has a hinge portion 21, which is rotatably connected to the cup body 10 via a pivot 22. The cover 20 can rotate relative to the cup body 10, thereby realizing the opening and closing of the dust outlet 11.

[0046] Furthermore, the hinge portion 21 is provided with a first receiving cavity 211 for placing the rotating shaft 22. The first receiving cavity 211 has a first side wall 2111. During the rotation of the cover 20 and / or when it is in the open position, the first side wall 2111 covers the space between the rotating shaft 22 and the inner cavity of the cup body 10. When the lid 20 is opened and closed, the first side wall 2111 blocks the space between the rotating shaft 22 and the inner cavity of the cup 10, preventing dust from the cup 10 from entering the hinge 21 of the lid 20. In other words, during the rotation of the lid 20, the first side wall 2111 blocks the space between the rotating shaft 22 and the ash outlet 11, preventing dust poured out from the ash outlet 11 from entering the hinge 21 of the lid 20, reducing dust accumulation in the first receiving cavity 211 of the hinge 21, reducing the rotational damping of the rotating shaft 22, thereby reducing the resistance of the lid 20 in opening and closing the cup 10, and ensuring the flexibility of the lid 20 in rotating relative to the cup 10.

[0047] According to the dust cup assembly 100 of this utility model embodiment, during the rotation of the cover 20, the first side wall 2111 blocks the space between the rotating shaft 22 and the inner cavity of the cup body 10, preventing the dust discharged from the cup body 10 from entering the hinge part 21, avoiding dust jamming on the hinge part 21 of the cover 20, and reducing the damping of the rotation of the rotating shaft 22.

[0048] Combination Figures 1 to 4 In some embodiments, a first sidewall 2111 is provided on the side of the rotating shaft 22 facing the inner cavity of the cup body 10 and extends in a direction parallel to the axis of the rotating shaft 22. The first sidewall 2111 is provided between the rotating shaft 22 and the inner cavity of the cup body 10 to separate the rotating shaft 22 and the inner cavity of the cup body 10.

[0049] Specifically, the first sidewall 2111 is located on the side of the first receiving cavity 211 closer to the inner cavity of the cup body 10. The rotating shaft 22 is located inside the first receiving cavity 211. The first sidewall 2111 extends along the axial direction of the rotating shaft 22 and blocks the space between the rotating shaft 22 and the inner cavity of the cup body 10. In other words, the first sidewall 2111 is located on the side of the first receiving cavity 211 closer to the ash outlet 11. When the lid 20 rotates, it blocks the space between the rotating shaft 22 and the ash outlet 11. When the lid 20 opens and closes the cup body 10, the first sidewall 2111 separates the rotating shaft 22 from the inner cavity of the cup body 10, preventing dust from entering the hinge portion 21 when the lid 20 is opened, reducing dust accumulation in the first receiving cavity 211, thereby reducing the rotational damping of the rotating shaft 22 and ensuring that the lid 20 can rotate smoothly relative to the cup body 10.

[0050] Combination Figures 5 to 7 In some embodiments, the peripheral wall of the ash pouring port 11 of the cup body 10 is provided with a notch 12, and the hinge part 21 is provided in the notch 12 to avoid the hinge part 21 being exposed to the external environment and to improve the stability of the hinge part 21 when rotating.

[0051] For example, the bottom of the cup body 10 may be provided with a bottom cover 14, and the ash outlet 11 is provided on the bottom cover 14. The bottom cover 14 may have a notch 12 on the side near the hinge part 21. The rotating shaft 22 inside the hinge part 21 can be rotatably connected to the side wall of the notch 12, so that the cover body 20 can rotate relative to the cup body 10 to open and close the ash outlet 11 of the cup body 10. The notch 12 is located in the inner cavity of the cup body 10. The hinge part 21 is located in the notch 12 to prevent the hinge part 21 from being directly exposed to the outside, which can avoid interference from external collisions and other factors to the hinge part 21, thereby reducing the impact of the external environment on the hinge part 21, ensuring the stability of the connection between the rotating shaft 22 inside the hinge part 21 and the cup body 10, and improving the service life of the hinge part 21.

[0052] In some embodiments, the cover 20 is tilted and opposite to the ash discharge port 11 when it is opened. For example, the dust cup assembly 100 can be detachably docked with the base station 2000. The base station 2000 may have a dust collection hood (not shown in the figures) and a dust collection bag (not shown in the figures). The dust collection hood can be used to guide the material in the cup 10 into the dust collection bag to prevent garbage and dust from leaking to the outside. When the dust cup assembly 100 is docked with the base station 2000, the cover 20 can open the ash discharge port 11. When the cover 20 opens the ash discharge port 11, it rotates into the interior of the dust collection hood and tilts downward from back to front, and the material in the cup 10 is discharged from the ash discharge port 11 into the dust collection hood. Since the opening angle of the cover 20 is limited by the dust collection hood, the opening angle of the cover 20 is limited to the range within the dust collection hood. The rotation path of the cover 20 can be short, which facilitates quick opening and closing of the ash discharge port 11.

[0053] Combination Figure 1 , Figure 2 and Figure 6 In some embodiments, the first receiving cavity 211 also has a second sidewall 2112, with the first sidewall 2111 and the second sidewall 2112 distributed on opposite sides of the rotating shaft 22. Specifically, the second sidewall 2112 is located on the side of the first receiving cavity 211 away from the inner cavity of the cup body 10. The first sidewall 2111 and the second sidewall 2112 surround the two sides of the rotating shaft 22, reducing the entry of dust from the external environment into the first receiving cavity 211 and preventing dust from accumulating at the rotating shaft 22, thereby reducing the rotational damping of the rotating shaft 22 and enabling the cover 20 to rotate stably relative to the cup body 10.

[0054] In some embodiments, during the rotation of the cover 20, the second sidewall 2112 blocks the space between the rotating shaft 22 and the cup body 10, preventing dust and other substances in the external space from entering the first receiving cavity 211, reducing the accumulation of dust at the rotating shaft 22, thereby reducing the rotational resistance of the rotating shaft 22.

[0055] Combination Figure 5 and Figure 6 In some embodiments, the hinge portion 21 further includes a first support 212 and a second support 213, the first support 212 and the second support 213 being distributed along the axis of the rotating shaft 22, and the rotating shaft 22 passing through the first support 212 and the second support 213. The first sidewall 2111 is connected to the first support 212 and the second support 213 at both ends along the axial direction of the rotating shaft 22, and the rotating shaft 22 passes through the first support 212 and the second support 213 and is rotatably connected to the cup body 10.

[0056] Specifically, the first support 212 and the second support 213 are fixedly connected to the rotating shaft 22. The rotating shaft 22 drives the first support 212 and the second support 213 to rotate, which in turn drives the entire lid 20 to rotate relative to the cup body 10, thus opening and closing the ash outlet 11. Simultaneously, the first support 212 and the second support 213 are located on opposite sides of the rotating shaft 22, ensuring a more even distribution of rotational force on the lid 20 and preventing damage due to excessive localized stress. Furthermore, the first support 212 and the second support 213 are connected to both sides of the first sidewall 2111, increasing the strength of the first support 212 and the second support 213 and separating the rotating shaft 22 from the inner cavity of the cup body 10, thereby reducing dust falling into the first receiving cavity 211 and preventing dust accumulation at the rotating shaft 22.

[0057] In some embodiments, the second sidewall 2112 is connected to the first support 212 and the second support 213 at both ends along the axial direction of the rotating shaft 22, and the two sides of the second sidewall 2112 are connected to the first support 212 and the second support 213, respectively, thereby improving the stress strength of the first support 212 and the second support 213 and separating the rotating shaft 22 from the external space, thereby reducing the entry of external dust into the first receiving cavity 211 and preventing dust accumulation at the rotating shaft 22.

[0058] Combination Figures 5 to 7 In some embodiments, the cup body 10 includes a main body 13 and a bottom cover 14. The lower end of the main body 13 is provided with an opening. The bottom cover 14 is placed over the opening, and the ash pouring port 11 is provided on the bottom cover 14. The cover body 20 is rotatably connected to the bottom cover 14 to facilitate opening and closing the ash pouring port 11. In addition, when the cover body 20 closes the ash pouring port 11, the cover body 20 is located inside the bottom cover 14 to ensure the sealing of the cover body 20 when closing the ash pouring port 11.

[0059] In conjunction with the foregoing, the bottom cover 14 is fixedly connected to the lower end of the main body 13. The bottom cover 14 has a notch 12 recessed into the inner cavity of the cup body 10, and the hinge part 21 is located within the notch 12. The bottom cover 14 has two opposing mounting holes 141, and the two ends of the rotating shaft 22 along the axial direction can respectively pass through the two mounting holes 141 to realize the rotation of the cover body 20 relative to the bottom cover 14. Among them, the bottom cover 14 has a first clearance groove 143. When the cover body 20 closes the ash pouring port 11, the cover body 20 rotates into the first clearance groove 143, so that the cover body 20 is located at the lower end of the main body 13. This prevents the cover body 20 from being exposed to the outside of the cup body 10 when the ash pouring port 11 is closed, reduces the interference of external factors on the cover body 20, ensures that the cover body 20 stably closes the ash pouring port 11, and prevents the leakage of substances inside the main body 13.

[0060] Optionally, a sealing ring 23 may be embedded in the end face of the cover 20 near the bottom cover 14 to further improve the sealing effect of the cover 20 when closing the ash outlet 11.

[0061] In some embodiments, the hinge portion 21 further includes an elastic element (not shown in the figures), which has an elastic force that drives the cover 20 to be in the closed ash outlet 11 state. The elastic element is sleeved on the outside of the rotating shaft 22, which can reduce the difficulty of closing the ash outlet 11 of the cover 20 and ensure that the cover 20 is always in the closed ash outlet 11 state. In conjunction with the foregoing, the dust cup assembly 100 can dock with the base station 2000. Under the action of external force, the elastic element twists and deforms, storing elastic force. The cover 20 can open the ash outlet 11, and the material inside the cup 10 can be discharged into the base station 2000. After the external force disappears, the elastic element releases the elastic force through elastic recovery and drives the cover 20 to close the ash outlet 11, causing the cover 20 to rotate to the vicinity of the ash outlet 11, reducing the difficulty of closing the ash outlet 11. At the same time, it ensures that after the dust cup assembly 100 is removed from the base station 2000, the cover 20 can keep the ash outlet 11 closed, preventing the material stored in the cup 10 from leaking to the outside.

[0062] Optionally, combined Figure 6 The elastic element can be a torsion spring, which is usually made of high-strength materials such as stainless steel, titanium alloy or alloy steel. It can provide a large energy output in a limited space, while having good fatigue resistance and durability and is not easy to fail. The torsion spring can have a torsion arm. The top of the second side wall 2112 can be provided with two first opening slots 214 along the axis of the rotating shaft 22. The torsion arm can be locked in the aforementioned first opening slots 214 so as to stably install the torsion spring in the first receiving cavity 211 and prevent it from falling off.

[0063] Combination Figures 8 to 13 According to another embodiment of the present invention, a dust cup assembly 100 includes a cup body 10 and a cover 20. The cup body 10 has a dust outlet 11 through which the material inside the cup body 10 can be discharged to the outside. The cover 20 is disposed on the dust outlet 11 of the cup body 10 and is used to open and close the dust outlet 11. When the cover 20 opens the dust outlet 11, the material inside the cup body 10 can be discharged to the outside through the dust outlet 11; when the cover 20 closes the dust outlet 11, the material is temporarily stored inside the cup body 10 to prevent the material from leaking to the outside.

[0064] Furthermore, the inner circumferential surface of the dust inlet 11 is provided with a second receiving cavity 15, and the cover 20 has a hinge portion 21. The hinge portion 21 is rotatably connected to the cup body 10 via a rotating shaft (not shown in the attached drawings). The dust cup assembly 100 has a second receiving cavity 15, and the second receiving cavity 15 has a third side wall 31. The third side wall 31 is located between the rotating shaft and the inner cavity of the cup body 10. The rotating shaft is located in the second receiving cavity 15. When the cover 20 opens and closes the cup body 10, the third side wall 31 is located between the rotating shaft and the inner cavity of the cup body 10, preventing dust in the cup body 10 from entering the hinge portion 21 of the cover 20. In other words, during the rotation of the cover 20, the third side wall 31 is located between the rotating shaft and the dust inlet 11, reducing dust accumulation at the rotating shaft, reducing the rotational damping of the rotating shaft, thereby reducing the resistance of the cover 20 in opening and closing the cup body 10, and ensuring the flexibility of the cover 20 in rotating relative to the cup body 10.

[0065] According to another embodiment of the present invention, in the dust cup assembly 100, during the rotation of the cover 20, the third side wall 31 blocks the space between the rotating shaft and the inner cavity of the cup body 10, preventing the dust discharged from the cup body 10 from entering the hinge part 21, avoiding dust jamming on the rotating shaft of the cover 20, and reducing the rotational damping of the rotating shaft.

[0066] In this utility model, the dust cup assembly 100 is provided with a second receiving cavity 15, and the third side wall 31 of the second receiving cavity 15 is used to shield the rotating shaft, including but not limited to the following embodiments.

[0067] In one embodiment, the second receiving cavity 15 is located on the peripheral wall of the ash outlet 11 and extends through the inner peripheral surface of the ash outlet 11. For example, a rotating shaft can be located within the second receiving cavity 15 and rotatably connected to the inner wall surface of the second receiving cavity 15. The hinge portion 21 of the cover 20 can be connected to the rotating shaft. When the rotating shaft rotates, the hinge portion 21 can drive the cover 20 to rotate relative to the cup body 10. The rotation of the cover 20 opens and closes the ash outlet 11. A third sidewall 31 can be located within the second receiving cavity 15. During the rotation of the cover 20, the third sidewall 31 is located on the side of the rotating shaft closer to the ash outlet 11, separating the rotating shaft from the ash outlet 11 and preventing dust from accumulating at the rotating shaft.

[0068] In the second embodiment, the second receiving cavity 15 can also be provided in the hinge portion 21, the rotating shaft can be provided inside the hinge portion 21, and the third side wall 31 can be provided on the side of the hinge portion 21, which can reduce the number of parts of the dust cup assembly 100; furthermore, during the rotation of the cover 20, the third side wall 31 on the hinge portion 21 can block the rotating shaft and the inner cavity of the cup body 10, that is, the third side wall 31 separates the rotating shaft from the ash outlet 11, preventing the dust discharged from the ash outlet 11 from entering the rotating shaft, preventing ash from getting stuck at the rotating shaft, thereby reducing the rotational damping of the rotating shaft.

[0069] Implementation method three, combined with Figures 8 to 10 The dust cup assembly 100 also includes a seal 30, which extends along the periphery of the dust outlet 11. When the cover 20 closes the dust outlet 11, the seal 30 seals the gap between the dust outlet 11 and the cover 20. A third side wall 31 is provided at one end of the seal 30 near the rotating shaft and is used to separate the hinge 21 and the inner cavity of the cup body 10.

[0070] Specifically, when the lid 20 closes the ash outlet 11, the sealing element 30 seals the gap between the lid 20 and the ash outlet 11, preventing the substance stored in the cup 10 from leaking to the outside, improving the sealing between the lid 20 and the ash outlet 11, and preventing dust from accumulating in the groove of the lid 20. When the lid 20 switches between opening and closing the inner cavity of the cup 10, the third sidewall 31 shields the area between the rotating shaft and the inner cavity of the cup 10, preventing dust from the inner cavity of the cup 10 from entering the hinge 21. In other words, during the process of opening and closing the ash outlet 11, the third sidewall 31 separates the rotating shaft and the ash outlet 11, preventing dust discharged from the ash outlet 11 from entering the rotating shaft, reducing dust accumulation in the hinge 21, thereby ensuring that the lid 20 can rotate easily relative to the cup 10.

[0071] Combination Figures 10 to 13 In some embodiments, the seal 30 is snapped together with the cover 20, and the seal 30 rotates simultaneously when the cover 20 rotates.

[0072] For example, the cover 20 may have a protrusion, and the seal 30 may have a corresponding groove. The protrusion is engaged with the groove, and the cover 20 can be tightly connected with the seal 30, thereby driving the seal 30 to rotate. The third side wall 31 may be provided at the end of the seal near the rotating shaft, so as to ensure that during the rotation of the cover 20, the third side wall 31 is shielded between the rotating shaft and the ash outlet 11, reducing the accumulation of dust at the rotating part of the rotating shaft, thereby reducing the rotational damping of the rotating shaft.

[0073] The bottom cover 14 may have a positioning protrusion and a moving groove on its top. The upper part of the third side wall 31 may have a positioning plate with a positioning hole. The third side wall 31 may move within the moving groove. When the cover 20 opens the ash outlet 11, the cover 20 drives the sealing element 30 to rotate to the open position. The positioning plate may connect with the top of the bottom cover 14. The positioning protrusion passes through the positioning hole to prevent the sealing element 30 from accidentally falling off. At the same time, the third side wall 31 blocks the space between the rotating shaft and the ash outlet 11, preventing the dust discharged from the ash outlet 11 from accumulating at the rotation point of the rotating shaft.

[0074] Additionally, the bottom cover 14 can be connected to the side wall of the opening. A second receiving cavity 15 can be provided at the end of the bottom cover 14 near the hinge portion 21. The hinge portion 21 is located within the second receiving cavity 15 and is rotatably connected to the side wall of the bottom cover 14 via a rotating shaft. The hinge portion 21 may also include an elastic element (not shown in the figures). The elastic element can be sleeved on the outside of the rotating shaft and has an elastic force to drive the cover 20 to close the ash outlet 11, thus enabling the cover 14 to open and close the ash outlet 11. The bottom cover 14 may also be provided with a second clearance groove 144. When the cover 20 closes the ash outlet 11, the cover 20 rotates into the second clearance groove 144, positioning the cover 20 at the lower end of the main body 13.
