Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of the above, an embodiment of the present invention aims to provide a dust cup, a vacuum cleaner, and a dust collection system in which the dust cover can more smoothly open and close the dust outlet.

Means for Solving the Problems

[0005] To achieve the above objective, a first embodiment of the present invention provides a dust cup comprising a cup body, a guide member, and a dust cover, wherein the cup body has a first dust collection chamber and a dust outlet that communicate with each other, the chamber wall of the first dust collection chamber on which the dust outlet is located is the target chamber wall, the guide member is connected to the cup body, the guide member extends along the target chamber wall, the direction in which the guide member extends is the first direction, the dust outlet is located at one end of the guide member in the first direction, and the guide member is capable of guiding one of the dust cover and the cup body to move along the first direction relative to the other of the dust cover and the cup body in order to open and close the dust outlet.

[0006] A second aspect of the present invention provides a vacuum cleaner comprising a vacuum cleaner body and a dust cup of any one embodiment, wherein the cup body is attached to the vacuum cleaner body.

[0007] A third aspect of the present invention provides a dust collection system comprising a base station and a vacuum cleaner according to one embodiment, wherein the base station has a second dust collection chamber and a dust collection port that communicate with each other, and when the base station and the dust cover are in contact, the dust cover can open the dust discharge port by the action of the base station, and at least a portion of the opened dust discharge port is located within the dust collection port so that the dust discharge port and the dust collection port communicate with each other.

[0008] A fourth aspect of the present invention provides a dust collection system comprising a base station and a dust cup, wherein the base station has a second dust collection chamber and a dust collection port communicating with each other, the dust cup comprises a cup body, a guide member and a dust cover, the cup body has a first dust collection chamber and a dust discharge port communicating with each other, the chamber wall of the first dust collection chamber where the dust discharge port is located is the target chamber wall, the guide member is connected to the cup body, the guide member extends along the target chamber wall and the direction of extension of the guide member is the first The dust outlet is located at one end of the guide member in the first direction, and the guide member is capable of guiding one of the dust cover and the cup body to move along the first direction relative to the other of the dust cover and the cup body so as to open and close the dust outlet, and when the base station and the dust cover come into contact, the dust cover can open the dust outlet by the action of the base station, and at least a portion of the opened dust outlet is located inside the dust collection port so as to communicate the dust outlet and the dust collection port.

[0009] In the embodiment of the present invention, the dust cup is moved along a first direction relative to the other of the dust cover and the cup body by the guidance of a guide member. The dust outlet is located at one end of the guide member in the first direction, and the movement path of the dust cover away from the dust outlet along the first direction is away from the dust outlet. When one of the dust cover and the cup body moves along the first direction relative to the other of the dust cover and the cup body, the dust cover is less affected by dust scattered from the dust outlet on most of the movement path away from the dust outlet along the first direction. Even if dust accumulates along the outer contour of the dust outlet for a long time, the scattered dust mainly accumulates at the end of the guide member on the dust outlet side, and the frictional resistance hardly increases due to the influence of dust scattered from the dust outlet on most of the movement path of the guide member away from the dust outlet along the first direction. Even if dust is scattered for a long period of time, the resistance with which one of the dust cover and the cup body moves along the first direction relative to the other of the dust cover and the cup body guided by the guide member does not change significantly. Therefore, even if dust is scattered for a long period of time, the dust cover can move smoothly along the first direction relative to the other of the dust cover and the cup body so that the dust cover can open and close the dust outlet relatively smoothly. Furthermore, since the guide member extends along the chamber wall of the first dust collection chamber, and the direction of movement of one of the dust cover and the cup body relative to the other of the dust outlet intersects with the direction of dust discharge at the dust outlet, the dust cover can be pushed away from the dust outlet along the chamber wall of the first dust collection chamber, opening the dust outlet, and there is no need to apply extra negative pressure suction force to open the dust outlet. Furthermore, when the dust cover is pushed away from the dust outlet along the wall of the target chamber, the dust cover and the dust outlet are shifted to some extent, reducing the shielding of the dust outlet by the dust cover, which is advantageous for the first dust collection chamber to discharge dust through the dust outlet.

Best Mode for Carrying Out the Invention

[0011] In addition, the embodiments of the present invention and the technical features in the embodiments can be combined with each other as long as they do not conflict. The detailed description in the specific embodiments should be understood as an explanation of the gist of the present invention and should not be regarded as an undue limitation to the present invention.

[0012] In the description of the embodiments of the present invention, the positions or positional relationships indicated by "upper", "lower", "top", "bottom", etc. are the positions or positional relationships based on FIG. 1. These position terms are only for the convenience and simplification of the description of the embodiments of the present invention, and the mentioned devices or elements are not necessarily indicated or implied to have a specific position and be constructed and operated at a specific position, so it can be understood that they should not be regarded as a limitation to the present invention. Exemplarily, as shown in FIG. 1, the up-down direction is the direction indicated by the arrow R1 in FIG. 1.

[0013] In the embodiments of the present invention, as shown in FIG. 7, the second direction is the direction indicated by the arrow R2 in the figure.

[0014] In the embodiments of the present invention, as shown in FIG. 6, the third direction is the direction indicated by the arrow R3 in the figure.

[0015] In the embodiments of the present invention, as shown in FIGS. 7, 13, 15 and 17, the dust discharge direction of the dust discharge port is the direction indicated by the arrow R4 in the figure.

[0016] In the related art, the dust cover is moved along a first direction with respect to the cup body to open and close the dust discharge port. The first direction in which the dust cover moves is close to the direction in which the outer contour of the dust discharge port extends, and the dust cover is provided partially straddling the dust discharge port along the first direction. By moving the dust cover along the first direction, the dust cover rubs against the cup body and / or the guide member along a long movement path along the outer contour of the dust discharge port. During dust discharge from the dust discharge port, dust may scatter near the outer contour of the dust discharge port. Due to the long-term accumulation of dust, the friction resistance between the dust cover and the cup and / or the guide member becomes large along a long movement path substantially along the outer contour of the dust discharge port, the movement resistance of the dust cover becomes large, and it becomes difficult for the dust cover to move smoothly, so it becomes difficult for the dust cover to open and close the dust discharge port smoothly.

[0017] Therefore, an embodiment of the present invention provides a dust cup 100. As shown in FIGS. 3, 5 to 8, 11 to 17, the dust cup 100 includes a cup body 1 in which a first dust collection chamber 11 and a dust discharge port 12 communicating with each other are formed. By configuring in this way, the first dust collection chamber 11 is for collecting dust such as garbage. When a sufficient amount of dust such as garbage is collected in the first dust collection chamber 11, the dust such as garbage in the first dust collection chamber 11 can be discharged through the dust discharge port 12.

[0018] In one embodiment, as shown in Figures 3, 5-9, and 11-17, the dust cup 100 further comprises a guide member 2 and a dust cover 4. The chamber wall of the first dust collection chamber 11 on which the dust outlet 12 is located is the target chamber wall, the guide member 2 is connected to the cup body 1, the guide member 2 extends along the target chamber wall, and the direction of extension of the guide member 2 is the first direction. The dust outlet 12 is located at one end of the guide member 2 in the first direction. The guide member 2 is capable of guiding one of the dust cover 4 and the cup body 1 to move along the first direction relative to the other of the dust cover 4 and the cup body 1 in order to open and close the dust outlet 12. With this configuration, the guide member 2 guides one of the dust cover 4 and the cup body 1 to move along the first direction relative to the other of the dust cover 4 and the cup body 1. The dust outlet 12 is located at one end of the guide member 2 along the first direction, and the path of the dust cover 4 moving away from the dust outlet 12 along the first direction is away from the dust outlet 12. When one of the dust cover 4 and the cup body 1 moves relative to the other of the dust cover 4 and the cup body 1 along the first direction, the dust cover 4 is affected by dust scattered from the dust outlet 12 for most of the path of movement away from the dust outlet 12 along the first direction. Even if dust accumulates along the outer contour of the dust outlet 12 for a long time, the scattered dust mainly accumulates at the end of the guide member 2 on the dust outlet side, and the frictional resistance does not increase significantly due to the dust scattered from the dust outlet 12 for most of the path of movement of the guide member 2 moving away from the dust outlet 12 along the first direction. Even if dust is scattered for a long period of time, the resistance with which one of the dust cover 4 and the cup body 1 moves along the first direction relative to the other, guided by the guide member 2, does not change significantly. Therefore, even if dust is scattered for a long period of time, one of the dust cover 4 and the cup body 1 can move smoothly along the first direction relative to the other, and the dust cover 4 can smoothly open and close the dust outlet 12.Furthermore, the guide member 2 extends along the chamber wall of the first dust collection chamber 11, and the direction of movement of one of the dust cover 4 and the cup body 1 relative to the other of the dust cover 4 and the cup body 1 at the dust outlet 12 intersects with the dust discharge direction of the dust outlet 12. As a result, the dust cover 4 can be pushed away from the dust outlet 12 along the chamber wall of the first dust collection chamber 11, opening the dust outlet 12, and there is no need to apply extra negative pressure suction force to open the dust outlet 12. Also, when the dust cover 4 is pushed away from the dust outlet 12 along the target chamber wall, the dust cover 4 and the dust outlet 12 are shifted from each other to some extent, reducing the shielding of the dust outlet 12 by the dust cover 4, which is advantageous for the first dust collection chamber 11 to discharge dust through the dust outlet 12.

[0019] In addition, it is possible for the dust cover 4 to move relative to the other of the dust cover 4 and the cup body 1, while the cup body 1 does not move.

[0020] In addition, the movement of one of the dust cover 4 and the cup body 1 relative to the other may be such that the dust cover 4 does not move, but the cup body 1 does.

[0021] In one embodiment, as shown in Figures 6, 7, 13, 15, and 17, one of the dust cover 4 and the cup body 1 can be translated relative to the other. For example, as shown in Figures 6, 7, 13, 15, and 17, the first direction is arranged along the vertical direction, and one of the dust cover 4 and the cup body 1 moves along the vertical direction relative to the other.

[0022] In one embodiment, one of the dust cover 4 and the cup body 1 can rotate relative to the other. For example, the cup body 1 is cylindrical, the guide member 2 extends along the circumferential direction of the cup body 1, i.e., the first direction, which is the direction in which the guide member 2 extends, is arranged along the circumferential direction surrounding the cup body 1, the dust cover 4 has an arc shape that conforms to the cylindrical shape of the cup body 1, the dust cover 4 moves along the first direction, i.e., the dust cover 4 rotates relative to the cup body 1 along the circumferential direction surrounding the cup body 1.

[0023] In one embodiment, as shown in Figures 6 to 8, the cup body 1 is cylindrical in shape, the dust discharge port 12 is located on the side wall 13 of the cup body 1, and the target chamber wall is the side wall 13 of the cup body 1. To make it clear, the side wall 13 of the cup body 1 belongs to a part of the chamber wall of the first dust collection chamber 11.

[0024] In one embodiment, the guide member 2 and the cup body 1 are integrally molded.

[0025] In one embodiment, the guide member 2 is attached to the cup body 1. The guide member 2 is manufactured as an independent part, and the molded guide member 2 is attached to the cup body 1.

[0026] In one embodiment, as shown in Figures 3, 5, and 8, the guide member 2 is located outside the cup body 1.

[0027] In one embodiment, as shown in Figures 6 and 7, the first direction is arranged along the vertical direction.

[0028] In one embodiment, as shown in Figures 13, 15, and 17, the first direction is positioned to intersect with the dust discharge direction of the dust discharge port.

[0029] In one embodiment, the first direction is perpendicular to the dust discharge direction of the dust outlet 12. For example, the first direction is arranged along the vertical direction, and the dust discharge direction of the dust outlet 12 is arranged along the approximately horizontal direction.

[0030] In one embodiment, as shown in Figures 5 to 8, the guide member 2 extends in a straight line. For example, the guide member 2 extends along the vertical direction.

[0031] In one embodiment, the cup body 1 is cylindrical in shape, and the guide member 2 extends in an arc shape along the circumferential direction surrounding the cup body 1.

[0032] In one embodiment, as shown in Figures 5 to 8, the guide member 2 extends in a straight line, and the dust discharge port 12 and the guide member 2 are aligned along the first direction.

[0033] In one embodiment, as shown in Figures 3, 5-9, and 11-17, a guide chamber 3 is provided surrounded by the guide member 2 and the cup body 1. The dust cover 4 is partially located within the guide chamber 3.

[0034] In one embodiment, as shown in Figures 3, 5-7, 9, 13, 15, and 17, the dust cover 4 comprises a restraining member 41 and a cover body 42, and a guide member 2 is capable of guiding one of the restraining member 41 and the cup body 1 to move relative to the other of the restraining member 41 and the cup body 1 along a first direction. The cover body 42 is connected to one end of the restraining member 41 on the dust outlet 12 side, and the cover body 42 is used to open and close the dust outlet 12. With this configuration, the direction of movement of the restraining member 41 is guided by the guide member 2. The restraining member 41, located in the guide chamber 3, is far from the dust outlet 12, is less affected by scattered dust, and the frictional resistance between the restraining member 41 and the guide member 2 and / or the cup body 1 is small. Therefore, one of the restraining member 41 and the cup body 1 can move relatively smoothly relative to the other of the restraining member 41 and the cup body 1, thereby allowing the cover body 42 connected to the restraining member 41 to move smoothly and open and close the dust discharge port 12.

[0035] In one embodiment, as shown in Figures 3, 5-7, 9, 13, 15, and 17, the restraining member 41 is located within the guide chamber 3. The restraining member 41 is movable within the guide chamber 3.

[0036] In one embodiment, the restraining member 41 is located inside the guide chamber 3, moves within the guide chamber 3, and does not leave the guide chamber 3.

[0037] In one embodiment, as shown in Figures 7, 13, 15, and 17, the restraining member 41 can exit the guide chamber 3.

[0038] In one embodiment, as shown in Figures 6, 7, and 9, in a direction intersecting the first direction, the gap between the restraining member 41 and the guide member 2 is smaller than the gap between the cover body 42 and the guide member 2, and / or the gap between the restraining member 41 and the cup body 1 is smaller than the gap between the cover body 42 and the cup body 1. With this configuration, because the gap between the restraining member 41 and the guide member 2 and / or the gap between the restraining member 42 and the cup body 1 is small, the guide member 2 restrains the dust cover 4 mainly by the restraining member 41. Because the gap between the cover body 42 and the guide member 2 and / or the gap between the cover body 42 and the cup body 1 is large, the possibility of the cover body 42 contacting the guide member 2 and / or the cup body 1 during movement is low or nonexistent. Therefore, during movement, the cover body 42 receives almost no frictional resistance from the guide member 2 and / or the cup body 1, resulting in reduced resistance during the movement of the dust cover 4, which is advantageous for the smooth movement of the dust cover 4.

[0039] In one embodiment, as shown in Figures 6, 7, and 9, the projection region of the cover body 42 in a first direction is located within the projection region of the restraint member 41 in a first direction.

[0040] To make it clear, the positional relationship between the projection area of ​​the cover body 42 in the first direction and the projection area of ​​the restraint member 41 in the first direction is not limited, and in one embodiment, at least a portion of the projection area of ​​the cover body 42 in the first direction may be located outside the projection area of ​​the restraint member 41 in the first direction.

[0041] In one embodiment, as shown in Figures 3, 5-7, and 9, the cover body 42 includes a cover plate 421, which is positioned intersecting the first direction. With this configuration, the cover plate 421 for closing the dust outlet 12 intersects the first direction, and accordingly, the surface on which the dust outlet 12 is located intersects the first direction. The cover plate 421 intersects the first direction, and the plate surface of the cover plate 421 is not parallel to the first direction, so that as the dust cover 4 moves along the first direction, the cover plate 421 intersecting the first direction can be pressed against the dust outlet 12. Furthermore, since both the cover plate 421 and the surface on which the dust outlet 12 is located intersect with the first direction, when the dust cover 4 moves along the first direction to open the dust outlet 12, the plate surface of the cover plate 4 that contacts the cup body 1 at the dust outlet immediately separates from the surface of the cup body 1 on which the dust outlet 12 is located, and the cover plate 421 hardly rubs against the cup body 1 and the dust outlet 12 during movement. When the dust cover 4 moves along the first direction to close the dust outlet 12, the cover plate 421 hardly touches the cup body 1 and the dust outlet 12 until the cover plate 421 closes the dust outlet 12. This reduces the frictional resistance of the cover plate 421 during movement, which is advantageous for the smooth movement of the dust cover 4.

[0042] For example, as shown in Figures 7, 13, 15, and 17, the first direction is positioned along the vertical direction, the cover plate is not positioned along the vertical direction, the lower end of the cover plate is inclined to the right as shown, and the first direction is positioned intersecting the cover plate whose lower end is inclined to the right.

[0043] In one embodiment, as shown in Figures 3, 5-7, and 9, the cover body 42 further includes reinforcing ribs 422 located on the side of the cover plate 421 away from the first dust collection chamber 11, and the reinforcing ribs 422 are connected to the cover plate 421. With this configuration, the reinforcing ribs 422 can perform a certain reinforcing effect on the cover plate 421, reducing the pressure deformation that occurs when the cover plate 421 closes the dust discharge port 12.

[0044] In one embodiment, there are multiple reinforcing ribs 422, and these multiple reinforcing ribs 422 are arranged at intervals. With this configuration, since the reinforcing ribs 422 are arranged at intervals, even if the reinforcing ribs 422 come into contact with the guide member 2, the contact area of ​​the reinforcing ribs 422 is small, which reduces the resistance to movement and is advantageous for the portion of the cover body 42 that enters the guide chamber 3 to move smoothly within the guide chamber 3.

[0045] In one embodiment, the cover body 42 does not need to be provided with reinforcing ribs 422.

[0046] In one embodiment, as shown in Figures 3, 5-7, 13, 15, and 17, the dust cup 100 further comprises an elastic member 5, one end of which contacts the dust cover 4, and the other end of which contacts the guide member 2 and / or the cup body 1, so that the elastic member 5 drives the dust cover 4 to move toward the dust outlet 12 so that the dust cover 4 closes the dust outlet 12. In this configuration, the elastic member 5 is used to drive the dust cover 4 to move toward the dust outlet 12 so that the dust cover 4 closes the dust outlet 12. The cup body 1 and guide member 2 can move relative to the dust cover 4 to open the dust outlet 12 against the elastic force of the elastic member 5. When the external force acting on the cup body 1 and / or guide member 2 is removed, the dust cover 4 returns to its original position due to the elastic force of the elastic member 5, which drives the dust cover 4 to move to a position that closes the dust outlet 12. When the dust cover 4 is in the state where the dust outlet 12 is open, the elastic member 5 can drive the dust cover 4 back to its original position, thereby achieving automatic closing of the dust outlet 12.

[0047] In one embodiment, as shown in Figures 3, 5-7, 13, 15, and 17, the elastic member 5 is located at the end of the dust cover 4 that is away from the dust outlet 12 in the first direction. With this configuration, the elastic member 5 is away from the dust outlet 12, and the influence of dust from the dust outlet 12 is reduced.

[0048] In one embodiment, as shown in Figures 3, 5-7, 13, 15, and 17, the elastic member 5 is located at one end of the restraining member 41 away from the cover body 42, with one end of the elastic member 5 in contact with the restraining member 41 and the other end of the elastic member 5 in contact with the guide member 2. The elastic member 5 is used to drive the restraining member 41 toward the dust discharge port 12 so that the cover body 42 closes the dust discharge port 12. With this structure, the elastic member 5 is located at one end of the restraining member 41 away from the cover body 42, and the elastic member 5 is used to drive the restraining member 41 toward the dust discharge port 12 so that the cover body 42 closes the dust discharge port 12. The cup body 1 and guide member 2 can move relative to the restraining member 41 against the elastic force of the elastic member 5 to open the dust outlet 12, and when the external force acting on the cup body 1 and / or guide member 2 is removed, the restraining member 41 moves toward the dust outlet 12 by the elastic force of the elastic member 5, driving the cover body 42 to close the dust outlet 12.

[0049] For example, when the elastic member 5 is located at one end of the dust cover 4 away from the dust outlet 12 in the first direction, the elastic member is in a compressed state.

[0050] To make it clear, the position of the elastic member 5 is not limited to the end of the dust cover 4 away from the dust outlet 12 in the first direction, and the elastic member 5 may be provided in other positions as needed. For example, the elastic member 5 may be located at the end of the dust cover 1 on the dust outlet 12 side in the first direction.

[0051] For example, when the elastic member 5 is located at one end of the dust cover 4 on the dust outlet 12 side in the first direction, the elastic member 5 is in a tensile state.

[0052] In one embodiment, the elastic member 5 may be a spring.

[0053] In one embodiment, a first hook is formed on the dust cover 4, and the dust cover 4 hooks one end of the elastic member 5 with the first hook so that the dust cover 4 contacts one end of the elastic member 5.

[0054] In one embodiment, a second hook is formed on one end of the guide member 2 that is away from the dust discharge port 12 in the first direction, and the guide member 2 hooks the other end of the elastic member 5 with the second hook so that the other end of the elastic member 5 contacts the guide member 2.

[0055] In one embodiment, the cup body 1 has a third hook located at one end of the elastic member 5 that is separated from the dust cover 4, and the cup body 1 hooks the other end of the elastic member 5 with the third hook so that the other end of the elastic member 5 contacts the cup body.

[0056] In one embodiment, the dust cup 100 does not need to be provided with an elastic member 5, and the dust cover 4 closes automatically by gravity or manually.

[0057] In one embodiment, as shown in Figures 6 and 7, the cup body 1 is cylindrical in shape, the dust outlet 12 is located on the side wall 13 of the cup body 1, the guide member 2 is connected to the side wall 13 of the cup body 1, and the first direction is arranged along the axial direction of the cup body 1.

[0058] For example, when the cup body 1 and the side wall 13 are connected, the axial direction of the cup body 1 is positioned approximately along the vertical direction during the process in which the dust discharge port 12 of the cup body 1 opens to discharge dust.

[0059] In one embodiment, as shown in Figures 6 and 7, the cup body 1 is cylindrical in shape, and the dust discharge direction of the dust discharge port 12 is positioned to intersect with the axial direction of the cup body 1.

[0060] In one embodiment, the dust discharge direction of the dust discharge port 12 is perpendicular to the axial direction of the cup body 1.

[0061] In one embodiment, as shown in Figures 6 and 7, the length of the cup body 1 in the axial direction is greater than the diameter of the cup body 1. With this configuration, the alignment direction of the guide member 2 and the dust outlet 12 is approximately close to the axial direction of the cup body 1. The cup body 1 is longer than its length in the axial direction, and the side wall 13 of the cup body 1 has sufficient space in the axial direction of the cup body 1 to position the guide member 2 and the dust cover 4.

[0062] Note that the side wall 13 of the cup body 1 refers to the wall of the cup body 1 that surrounds the central axis of the cup body 1.

[0063] In one embodiment, as shown in Figures 6, 7, and 8, one end of the cup body 1 in the axial direction is the first end, and the other end of the cup body 1 in the axial direction is the second end. The distance between the dust outlet 12 and the end face of the first end of the cup body 1 is greater than the distance between the dust outlet 12 and the end face of the second end of the cup body 1, and the guide member 2 is positioned between the dust outlet 12 and the end face of the first end of the cup body 1. With this structure, the length between the guide member 2 and the end face of the first end is long, and sufficient space is provided to guide the dust cover 4 to move along the first direction.

[0064] In one embodiment, as shown in Figures 2 to 8, 13, 15, and 17, the first direction is parallel to the axial direction of the cup body 1.

[0065] In one embodiment, the cup body 1 is cylindrical in shape, the dust outlet 12 may be located at one end of the cup body 1 in the axial direction of the cup body 1, and the guide member 2 is connected to the end wall 14 of the cup body 1. The first direction is arranged to intersect with the axial direction of the cup body 1.

[0066] For example, when the guide member 2 and the end wall 14 of the cup body 1 are connected, the dust discharge port 12 of the cup body 1 opens and dust is discharged. In this process, the axial direction of the cup body 1 is positioned approximately horizontally, and the first direction is positioned approximately vertically.

[0067] Furthermore, the end wall 14 of the cup body 1 is located at one end of the cup body 1 in the axial direction of the cup body 1, and the end wall 14 of the cup body 1 does not surround the central axis of the cup body 1.

[0068] In one embodiment, the side wall 13 of the cup body 1 is an annular curved surface, and the bottom wall of the cup body 1 is flat.

[0069] In one embodiment, the angle between the first direction and the axial direction of the cup body 1 is large, and the first direction is nearly perpendicular to the axial direction of the cup body 1.

[0070] In one embodiment, the first direction is perpendicular to the axial direction of the cup body 1.

[0071] In one embodiment, as shown in Figures 6, 7, 13, 15, and 17, the first direction may be arranged along the vertical direction. This configuration makes it easier for the dust cover 4 to open and close the dust outlet 12.

[0072] In one embodiment, as shown in Figures 5, 7, 8, 13, 15, and 17, the bottom wall of the dust outlet 12 protrudes from the cup body 1 along the dust discharge direction of the dust outlet 12. With this configuration, the bottom of the dust outlet 12 extends toward the dust collection port 402, allowing for efficient dust discharge and reducing leakage of dust and other debris from the bottom of the dust outlet 12.

[0073] An embodiment of the present invention provides a vacuum cleaner 300, which, as shown in Figures 1, 2, 4, 11, 12, 14, and 16, comprises a vacuum cleaner body 200 and a dust cup 100 of any of the above embodiments, with the cup body 1 attached to the vacuum cleaner body 200. With this configuration, the vacuum cleaner body 200 sucks up dust and other debris from the surface of the object to be cleaned, and the dust and other debris is sucked into the first dust collection chamber 11 of the dust cup 100.

[0074] An embodiment of the present invention provides a dust collection system, which, as shown in Figures 1, 10, 11, 12, 14, and 16, comprises a base station 400 having a second dust collection chamber 401 and a dust collection port 402 that communicate with each other. With this configuration, the second dust collection chamber 401 of the base station 400 collects dust and other debris through the dust collection port 402.

[0075] In one embodiment, the axial direction of the dust cup substantially coincides with the extending direction of the handle of the vacuum cleaner unit.

[0076] As an embodiment, as shown with reference to Figures 1, 2, 4, 11, 12, 14, and 16, the dust collection system further comprises a vacuum cleaner 300 or a dust cup 100 of any of the embodiments described above.

[0077] In one embodiment, as shown in Figures 13, 15, and 17, when the base station 400 contacts the dust cover 4, the dust cover 4 can open the dust outlet 12 by the action of the base station 400, and at least a portion of the opened dust outlet 12 is located inside the dust collection port 402 so that the dust outlet 12 and the dust collection port 402 are in communication. With this configuration, when it is necessary to discharge dust and other debris from the first dust collection chamber 11, the dust cover 4 is brought into contact with the base station 400, and the dust cover 4 opens the dust outlet 12 by the action of the base station 400. Since at least a portion of the opened dust outlet 12 is located inside the dust collection port 402 so that the dust outlet 12 and the dust collection port 402 are in communication, dust and other debris from the first dust collection chamber 11 enter the second dust collection chamber 401 of the base station 400 through the dust outlet 12 and the dust collection port 402. This allows dust and other debris in the first dust collection chamber 11 to be discharged into the second dust collection chamber 401 of the base station 400, reducing the amount of dust generated during the discharge process from the first dust collection chamber 11 and improving the user experience. The dust cover 4 opens the dust discharge port 12 by the action of the base station 400, thus reducing the user's involvement in the process of opening the dust discharge port 12, simplifying operation, lowering the user's workload, and improving the user experience.

[0078] The piping connected to the dust collection port 402 in the base station 400 belongs to the second dust collection chamber 401.

[0079] For example, the first orientation is arranged along the vertical direction, the dust cover 4 is in contact with the base station 400 so as not to move, and the cup body 1 moves downward relative to the dust cover 4 to open the dust outlet 12.

[0080] For example, the first orientation is arranged along the vertical direction, the dust cover 4 is in contact with the base station 400, the cup body 1 does not move, and the base station 400 drives the dust cover 4 upward to open the dust outlet 12.

[0081] For example, the first direction is arranged along the vertical direction, and the guide member 2 is located above the dust outlet 12. When it is necessary to discharge dust and other debris from the first dust collection chamber 11, the user holds the vacuum cleaner 300 in their hand and moves the dust cup 100 from top to bottom relative to the base station 400, bringing the dust cover 4 into contact with the base station 400. The user then holds the vacuum cleaner 300 in their hand and moves the cup body 1 of the dust cup 100 downwards, opening the dust outlet 12 in the dust cover 4, at which point dust and other debris from the first dust collection chamber 11 are discharged into the second dust collection chamber 401 through the dust outlet 12 and the dust collection port 402. Once the dust discharge from the first dust collection chamber 11 is complete, the user holds the vacuum cleaner 300 in their hand and lifts it away from the base station 400.

[0082] Exemplary, the first direction is arranged along the vertical direction, and the guide member 2 is located above the dust outlet 12, and the dust cup 100 can be removed from the vacuum cleaner 300 when it is necessary to discharge dust and other debris from the first dust collection chamber 11. The user can move the removed dust cup 100 from top to bottom relative to the base station 400, bringing the dust cover 4 into contact with the base station 400, and when the user then moves the cup body 1 of the dust cup 100 downwards, opening the dust outlet 12 in the dust cover 4, the dust and other debris from the first dust collection chamber 11 is discharged to the second dust collection chamber 401 through the dust outlet 12 and the dust collection port 402. Once the dust discharge from the first dust collection chamber 11 is complete, the user lifts the dust cup 100 to move it away from the base station 400.

[0083] To make it easier to understand, the dust cup 100 further includes an elastic member 5, which drives a restraining member 41 to move toward the dust outlet 12, causing the cover body 42 to close the dust outlet 12. When the user lifts the vacuum cleaner 300 or the dust cup 100, the dust cover 4 automatically closes the dust outlet 12 by the elastic force of the spring.

[0084] In one embodiment, at least a portion of the dust collection port 402 is exposed from the dust cover 4.

[0085] In one embodiment, the open dust discharge port 12 is located inside the dust collection port 402 so as to connect the dust discharge port 12 with the dust collection port 402.

[0086] Furthermore, the statement that at least a portion of the open dust discharge port 12 is located within the dust collection port 402 means that, in the dust discharge direction of the dust discharge port 12, at least a portion of the projection area of ​​the dust discharge port 12 is located within the projection area of ​​the dust collection port 402.

[0087] Furthermore, when we say that the open dust discharge port 12 is located inside the dust collection port 402, it means that in the dust discharge direction of the dust discharge port 12, the projected area of ​​the dust discharge port 12 is located inside the dust collection port 402.

[0088] In one embodiment, as shown in Figures 3, 5-8, 13, 15, and 17, a clearance groove 21 is formed on the side of the guide member 2 away from the cup body 1, a boss 43 is formed on the dust cover 4 that penetrates the clearance groove 21, and the base station 400 has an operating part 403 for which the boss 43 makes contact. With this configuration, the operating part 403 of the base station 400 makes contact with the boss 43, allowing the dust cover 4 to easily open the dust outlet 12.

[0089] In one embodiment, as shown in Figures 3, 5-8, 13, 15, and 17, the avoidance groove 21 is positioned to guide the guide member 2 to move along the direction of extension of the avoidance groove 21 on the boss 43, and the avoidance groove 21 performs a guiding function to some extent and contacts the boss 43 of the dust cover 4 via the actuation part 403 of the base station 400.

[0090] To make it clear, the boss 43 penetrates the avoidance groove 21 of the guide member 2, and the position of the boss 43 is far from the dust outlet 12, so the base station 400 needs to ensure sufficient space on the dust collection port 402 side of the operating part 403 to avoid the cup body 1 moving relative to the dust cover 4.

[0091] In one embodiment, the operating unit 403 protrudes from the base station 400 on the side away from the dust collection port 402. With this configuration, since the operating unit 403 protrudes from the base station 400 on the side away from the dust collection port 402, the base station 400 can have enough space on the dust collection port 402 side of the operating unit 403 to accommodate the cup body 1 that moves relative to the dust cover 4, and the sufficient opening of the dust discharge port 12 is advantageous for discharging dust and other debris from the first dust collection chamber 11.

[0092] In one embodiment, as shown in Figures 10, 13, 15, and 17, the first direction is arranged along the vertical direction, and the operating unit 403 is located above the dust collection port 402. With this configuration, in the process of the vacuum cleaner 300 or dust cup 100 being placed on the base station 400 to discharge dust, the dust cup 100 is placed on the base station 400 from top to bottom, so that the base station 400 comes into contact with the bottom of the dust cover 4, moving the dust cover 4 almost upward and opening the dust discharge port 12. As the vacuum cleaner 300 or dust cup 100 is placed on the base station 400 from top to bottom, the actuation unit 403 is positioned above the dust collection port 402. This is advantageous for bringing the dust cover 4 into contact with the base station 400 before it obstructs the dust collection port 402 or before it slightly obstructs it. This reduces the risk of the base station 400 or dust cup 100 interfering with the dust collection port 402 at the point where the base station 400 and dust cup 100 come into contact, and the degree of interference of the dust cover 4 with the dust collection port 402, thereby reducing the space occupied on both sides of the dust collection port 402. Since the operating part 403 is located above the dust collection port 402, when the dust collection device is placed on the base station 400 from top to bottom, the part of the dust cover 4 that contacts the base station 400 does not need to avoid the dust collection port 402, which is advantageous for the dust cover 4 to receive force uniformly and move smoothly relative to the vacuum cleaner body 200.

[0093] In one embodiment, as shown in Figures 6 and 7, the direction in which the guide member 2 and the cup body 1 are aligned is the second direction, and the direction that intersects both the second direction and the first direction is the third direction.

[0094] In one embodiment, as shown in Figures 6 and 10, guide portions 22 are formed on opposite sides of the guide member 2 in a third direction, and the guide portions 22 are separated from the guide chamber 3. Guide grooves 404 are formed in the base station 400, and guide grooves 404 are provided on opposite sides of the dust collection port 402. When the guide portion 22 is located in the guide grooves 404, the guide grooves 404 are arranged to extend in a first direction, and one guide groove 404 opens toward the other guide groove 404. In this way, the guide portion 22 of the guide member 2 is inserted into the guide grooves 404, and the base station 400 guides the direction of movement of the guide portion 22 in the guide grooves 404, and guides the direction of movement of the dust cup 100. One guide groove 404 opens toward the other guide groove 404, and the guide groove 404 does not have an opening in the direction of receiving the dust collection port 402. This restrains the guide portion 22 of the guide member 2 and prevents the dust cup 100 from detaching from the base station 400 during the process of moving and discharging dust.

[0095] As shown in Figures 6, 7, and 10, the receiving direction of the dust collection port 402 is positioned approximately along the second direction.

[0096] In one embodiment, as shown in Figures 12 to 17, the base station 400 is positioned to contact the bottom of the dust cover 4. In this manner, the base station 400 pushes the dust cover 4 almost upward and moves it relative to the vacuum cleaner unit 200, thereby opening the dust outlet 12.

[0097] In one embodiment, as shown in Figures 12 to 17, the base station 400 is positioned to abut the bottom of the dust cover 4, and the first orientation is aligned vertically.

[0098] In one embodiment, as shown in Figures 12 to 17, when the base station 400 contacts the lower part of the dust cover 4, the lowest position of the dust cover 4 is located between the highest and lowest positions of the dust collection port 402 in the vertical direction.

[0099] In one embodiment, as shown in Figures 12 to 17, when the base station 400 contacts the bottom of the dust cover 4, the lowest position of the dust collection port 402 is lower than the lowest position of the dust cover 4, and the lowest position of the dust cover 4 is located between the highest and lowest positions of the dust collection port 402 in the vertical direction. With this configuration, when the base station 400 contacts the bottom of the dust cover 4, the lowest position of the dust cover 4 is higher than the lowest position of the dust collection port 402, and the dust collection port 402 is not completely blocked by the dust cover 4 in the vertical direction. When the vacuum cleaner unit 200 moves downward, the base station 400 moves the dust cover 4 relative to the vacuum cleaner unit 200 to open the dust discharge port 12, so that dust and other debris discharged from the dust discharge port 12 can enter the second dust collection chamber 401 through the dust collection port 402, which is not completely blocked by the dust cover 4 in the vertical direction.

[0100] In one embodiment, as shown in Figures 12 to 17, when the base station 400 contacts the bottom of the dust cover 4, the lowest position of the dust cover 4 is lower than the highest position of the dust collection port 402. With this configuration, when the base station 400 contacts the bottom of the dust cover 4 and the dust discharge port 12 moves downward and is exposed from the dust cover 4, the highest position of dust discharge where the dust discharge port 12 is exposed is approximately at the lowest position of the dust cover 4. Because the lowest position of the dust cover 4 is lower than the highest position of the dust collection port 402, the dust and other debris discharged from the dust discharge port 12 does not rise higher than the highest position of the dust collection port 402. If the lowest position of the dust collection port 402 is lower than the lowest position of the dust cover 4 and the dust collection port 402 is not completely blocked by the dust cover 4, the discharged dust and other debris is well received by the dust collection port 402, and the amount of dust stirred up during the process of dust and other debris being discharged can be reduced.

[0101] In one embodiment, as shown in Figures 12 to 17, when the base station 400 contacts the dust cover 4 and moves the dust cover 4 relative to the vacuum cleaner unit 200 to open the dust outlet 12, the lowest position of the dust outlet 12 is higher than the lowest position of the dust collection port 402. This is advantageous because the dust collection port 402 can effectively receive dust and other debris discharged from the dust outlet 12, thereby reducing the amount of dust generated.

[0102] In one embodiment, as shown in Figures 13, 15, and 17, the restraining member 41 is for contacting the base station 400.

[0103] In one embodiment, as shown in Figures 13, 15, and 17, the boss 43 is formed on the restraining member 41 and the boss 43 abuts against the base station 400.

[0104] In one embodiment, as shown in Figures 13, 15, and 17, the orientation of the dust collection port 402 and the direction of movement of the dust cover 4 are arranged to intersect.

[0105] For example, as shown in Figures 13, 15, and 17, the first direction in which the dust cover 4 moves is aligned vertically, and the orientation of the dust collection port 402 is aligned approximately horizontally.

[0106] In one embodiment, as shown in Figures 13, 15, and 17, the dust collection port 402 faces directly opposite the dust discharge port 12.

[0107] In one embodiment, as shown in Figures 13, 15, and 17, the direction in which the dust collection port 402 and the dust discharge port 12 are aligned intersects with the direction of movement of the dust cover 4.

[0108] The foregoing are merely preferred embodiments of the present invention and do not limit it. Those skilled in the art can make various modifications and changes to the present invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
