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 discharge port.

Means for Solving the Problems

[0005] To achieve the above object, a first aspect of an embodiment of the present invention provides a dust cup, which includes a cup body, a guide member, and a dust cover. In the cup body, a first dust collection chamber and a dust discharge port that communicate with each other are formed. Among the chamber walls of the first dust collection chamber, the chamber wall where the dust discharge port is located is the target chamber wall. The guide member is connected to the cup body, extends along the target chamber wall, the extending direction of the guide member is a first direction, the dust discharge port is located at one end of the guide member in the first direction, and the guide member can guide 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 discharge port.

[0006] A second aspect of the present invention provides a vacuum cleaner, which includes a main body of the vacuum cleaner and a dust cup according to any one of the embodiments, and the cup body is attached to the main body of the vacuum cleaner.

[0007] A third aspect of the present invention provides a dust collection system, which includes a base station and a vacuum cleaner according to any one of the embodiments. In the base station, a second dust collection chamber and a dust collection port that communicate with each other are formed. When the base station and the dust cover are in contact, the dust cover can open the dust discharge port under the action of the base station, and at least a part of the opened dust discharge port is located in 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, the dust collection system comprising a base station and a dust cup. In the base station, a second dust collection chamber and a dust collection port that communicate with each other are formed. The dust cup includes a cup body, a guide member, and a dust cover. In the cup body, a first dust collection chamber and a dust discharge port that communicate with each other are formed. Among the chamber walls of the first dust collection chamber, the chamber wall where the dust discharge port is located is the target chamber wall. The guide member is connected to the cup body and extends along the target chamber wall. The extending direction of the guide member is a first direction. The dust discharge port is located at one end of the guide member in the first direction. The guide member is capable of guiding one of the dust cover and the cup body to move along the first direction with respect to the other of the dust cover and the cup body so as to open and close the dust discharge port. When the base station and the dust cover are in contact with each other, the dust cover can open the dust discharge port under the action of the base station, and at least a part of the opened dust discharge port is located in the dust collection port so that the dust discharge port and the dust collection port communicate with each other.

[0009] In the dust cup according to an embodiment of the present invention, one of the dust cover and the cup body is moved along a first direction relative to the other of the dust cover and the cup body under the guidance of a guide member. The dust discharge port is located at one end of the guide member in the first direction, and the movement path along which the dust cover moves away from the dust discharge port in the first direction is away from the dust discharge port. 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 influence of the dust scattered from the dust discharge port received on most of the movement paths along which the dust cover moves away from the dust discharge port in the first direction is small. Even if dust accumulates along the outer contour of the dust discharge port for a long time, the scattered dust mainly accumulates at one end of the guide member on the dust discharge port side. On most of the movement paths along which the guide member moves away from the dust discharge port in the first direction, there is almost no increase in frictional resistance due to the influence of the dust scattered from the dust discharge port. Even if dust scatters for a long time, the resistance of 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 under the guidance of the guide member does not change significantly. Therefore, even if dust scatters for a long time, one of the dust cover and the cup body 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 discharge port relatively smoothly. Further, since the guide member extends along the chamber wall of the first dust collection chamber, and the movement direction at the dust discharge port of one of the dust cover and the cup body relative to the other of the dust cover and the cup body intersects the dust discharge direction at the dust discharge port, the dust cover can be pushed away from the dust discharge port along the chamber wall of the first dust collection chamber to open the dust discharge port, and there is no need to apply an extra negative pressure suction force to open the dust discharge port. Further, when the dust cover is pushed away from the dust discharge port along the target chamber wall, the dust cover and the dust discharge port are displaced from each other to a certain extent, reducing the shielding of the dust discharge port by the dust cover, which is advantageous for the first dust collection chamber to discharge dust through the dust discharge port.

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 "up", "down", "top", "bottom", etc. are the positions or positional relationships based on FIG. 1. These position terms are for the convenience and simplification of the description of the embodiments of the present invention only, and it should be understood that the devices or elements mentioned are not necessarily indicated or implied to have a specific position and be constructed and operated at a specific position, so it 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 embodiment 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 embodiment 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 embodiment 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, a dust cover is moved relative to a cup body along a first direction to open and close a dust outlet. The first direction in which the dust cover moves is close to the direction in which the outer contour of the dust outlet extends, and the dust cover is provided so as to partially straddle the dust outlet along the first direction. By moving the dust cover along the first direction, the dust cover rubs against the cup body and / or a guide member along a long movement path along the outer contour of the dust outlet. During dust discharge from the dust outlet, dust may scatter near the outer contour of the dust outlet. Due to the long-term accumulation of dust, the friction resistance between the dust cover and the cup and / or the guide member increases along a long movement path substantially along the outer contour of the dust outlet, the movement resistance of the dust cover increases, 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 outlet smoothly.

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

[0018] In one embodiment, as shown in FIGS. 3, 5 to 9, and 11 to 17, the dust cup 100 further includes a guide member 2 and a dust cover 4. Among the chamber walls of the first dust collection chamber 11, the chamber wall where the dust discharge port 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 extending direction of the guide member 2 is the first direction. The dust discharge port 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 with respect to the other of the dust cover 4 and the cup body 1 so as to open and close the dust discharge port 12. With such a configuration, by the guidance of the guide member 2, one of the dust cover 4 and the cup body 1 is moved along the first direction with respect to the other of the dust cover 4 and the cup body 1. The dust discharge port 12 is located at one end of the guide member 2 along the first direction, and the movement path where the dust cover 4 moves away from the dust discharge port 12 along the first direction is away from the dust discharge port 12. When one of the dust cover 4 and the cup body 1 moves along the first direction with respect to the other of the dust cover 4 and the cup body 1, the influence of the dust scattered from the dust discharge port 12 received in most of the movement path where the dust cover 4 moves away from the dust discharge port 12 along the first direction is small. Even if dust accumulates along the outer contour of the dust discharge port 12 for a long time, the scattered dust mainly accumulates at one end of the guide member 2 on the dust discharge port side. In most of the movement path where the guide member 2 moves away from the dust discharge port 12 along the first direction, the influence of the dust scattered from the dust discharge port 12 is received, and the frictional resistance hardly increases. Even if dust scatters for a long time, the resistance for one of the dust cover 4 and the cup body 1 to move along the first direction with respect to the other of the dust cover 4 and the cup body 1 under the guidance of the guide member 2 does not change significantly. Therefore, even when dust scatters for a long time, one of the dust cover 4 and the cup body 1 can smoothly move along the first direction with respect to the other of the dust cover 4 and the cup body 1, and the dust cover 4 can smoothly open and close the dust discharge port 12.Furthermore, the guide member 2 extends along the chamber wall of the first dust collection chamber 11, and the moving direction of one of the dust cover 4 and the cup body 1 with respect to the other of the dust cover 4 and the cup body 1 at the dust discharge port 12 intersects the dust discharge direction of the dust discharge port 12. Therefore, the dust cover 4 can be pushed out from the dust discharge port 12 along the chamber wall of the first dust collection chamber 11 to open the dust discharge port 12, and there is no need to apply an extra negative pressure suction force to open the dust discharge port 12. Also, when the dust cover 4 is pushed out from the dust discharge port 12 along the target chamber wall, the dust cover 4 and the dust discharge port 12 are displaced from each other to a certain extent, reducing the shielding of the dust discharge port 12 by the dust cover 4, which is advantageous for the first dust collection chamber 11 to discharge dust through the dust discharge port 12.

[0019] Note that as the movement of one of the dust cover 4 and the cup body 1 with respect to the other of the dust cover 4 and the cup body 1, it may be that the dust cover 4 moves while the cup body 1 does not move.

[0020] Note that as the movement of one of the dust cover 4 and the cup body 1 with respect to the other of the dust cover 4 and the cup body 1, it may be that the dust cover 4 does not move while the cup body 1 moves.

[0021] In one embodiment, as shown in FIGS. 6, 7, 13, 15, and 17, one of the dust cover 4 and the cup body 1 can translate with respect to the other. For example, as shown in FIGS. 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 with respect to the other.

[0022] In one embodiment, one of the dust cover 4 and the cup body 1 can rotate relative to the other of the dust cover 4 and the cup body 1. For example, the shape of the cup body 1 is cylindrical, the guide member 2 extends along the circumferential direction of the cup body 1, that is, the first direction which is the extending direction of the guide member 2 is arranged along the circumferential direction surrounding the cup body 1, the shape of the dust cover 4 presents an arc shape conforming to the cylindrical shape of the cup body 1, the dust cover 4 moves along the first direction, that is, 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 FIGS. 6 to 8, the shape of the cup body 1 is cylindrical, the dust outlet 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. As can be understood, 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 formed.

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

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

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

[0028] In one embodiment, as shown in FIGS. 13, 15, and 17, the first direction is arranged to intersect the dust discharge direction of the dust outlet.

[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 substantially along the horizontal direction.

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

[0031] In one embodiment, the shape of the cup body 1 is cylindrical, 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 FIGS. 5 to 8, the guide member 2 extends linearly, and the dust outlet 12 and the guide member 2 are arranged side by side along the first direction.

[0033] In one embodiment, as shown in FIGS. 3, 5 to 9, 11 to 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 in the guide chamber 3.

[0034] In one embodiment, as shown in FIGS. 3, 5 to 7, 9, 13, 15 and 17, the dust cover 4 includes a restraint member 41 and a cover body 42, and the guide member 2 is capable of guiding one of the restraint member 41 and the cup body 1 to move along the first direction relative to the other of the restraint member 41 and the cup body 1. The cover body 42 is connected to one end of the restraint member 41 on the side of the dust outlet 12, and the cover body 42 is used to open and close the dust outlet 12. By configuring in this way, the moving direction of the restraint member 41 is guided by the guide member 2. The restraint member 41 in the guide chamber 3 is away from the dust outlet 12, less affected by scattered dust, and has a small frictional resistance between the restraint member 41 and the guide member 2 and / or the cup body 1. Therefore, one of the restraint member 41 and the cup body 1 can move relatively smoothly relative to the other of the restraint member 41 and the cup body 1, so as to smoothly move the cover body 42 connected to the restraint member 41 to open and close the dust outlet 12.

[0035] In one embodiment, as shown in FIGS. 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 within the guide chamber 3, the restraining member 41 moves within the guide chamber 3, and the restraining member 41 does not exit the guide chamber 3.

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

[0038] In one embodiment, as shown in FIGS. 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 such a configuration, since 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 mainly restrains the dust cover 4 by the restraining member 41. Since 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 that the cover body 42 contacts the guide member 2 and / or the cup body 1 during movement is low or there is no contact. Therefore, the cover body 42 hardly receives the frictional resistance of the guide member 2 and / or the cup body 1 during movement, so the resistance during the movement of the dust cover 4 is reduced, which is advantageous for the smooth movement of the dust cover 4.

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

[0040] To be understandable, 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. In one embodiment, at least a part 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 FIGS. 3, 5 to 7, and 9, the cover body 42 includes a cover plate 421, and the cover plate 421 is disposed to intersect the first direction. By configuring in this way, the cover plate 421 for closing the dust outlet 12 intersects the first direction, and accordingly, the surface where 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. By moving the dust cover 4 along the first direction, the cover plate 421 intersecting the first direction can be pressed against the dust outlet 12. Further, since both the cover plate 421 and the surface where the dust outlet 12 is located intersect 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 detaches from the surface of the cup body 1 where 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, until the cover plate 421 closes the dust outlet 12, the cover plate 421 hardly contacts the cup body 1 and the dust outlet 12. This reduces the frictional resistance during the movement of the cover plate 421, which is advantageous for the smooth movement of the dust cover 4.

[0042] For example, as shown in FIGS. 7, 13, 15, and 17, the first direction is arranged along the vertical direction, the cover plate is not arranged along the vertical direction, the lower end of the cover plate is inclined to the right side as shown in the figure, and the first direction intersects the cover plate with the lower end inclined to the right side.

[0043] In one embodiment, as shown in FIGS. 3, 5 to 7, and 9, the cover body 42 further includes a reinforcing rib 422 located on the side away from the first dust collection chamber 11 of the cover plate 421, and the reinforcing rib 422 is connected to the cover plate 421. By configuring in this way, the reinforcing rib 422 can exert a certain reinforcing effect on the cover plate 421, and reduce the pressing deformation caused by the cover plate 421 closing the dust discharge port 12.

[0044] In one embodiment, the number of the reinforcing ribs 422 is plural, and the plural reinforcing ribs 422 are arranged at intervals. By configuring in this way, since the reinforcing ribs 422 are arranged at intervals, even if the reinforcing ribs 422 contact the guide member 2, the contact area of the reinforcing ribs 422 is small, and accordingly, the movement resistance is small, which is advantageous for the portion entering the guide chamber 3 of the cover body 42 to move smoothly within the guide chamber 3.

[0045] In one embodiment, the cover body 42 may not be provided with the reinforcing rib 422.

[0046] In one embodiment, as shown in FIGS. 3, 5-7, 13, 15, and 17, the dust cup 100 further includes an elastic member 5. One end of the elastic member 5 contacts the dust cover 4, and the other end of the elastic member 5 contacts the guide member 2 and / or the cup body 1. 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. With such a 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 the 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 the guide member 2 is removed, the dust cover 4 returns to its original position by the elastic force of the elastic member 5, and the elastic force of the elastic member 5 drives the dust cover 4 to move to a position where the dust cover 4 closes the dust outlet 12. When the dust cover 4 opens the dust outlet 12, the elastic member 5 can drive the dust cover 4 to return to its original position, realizing the automatic closing of the dust outlet 12.

[0047] In one embodiment, as shown in FIGS. 3, 5-7, 13, 15, and 17, the elastic member 5 is located at an end portion of the dust cover 4 that is separated from the dust outlet 12 in the first direction. With such a configuration, the elastic member 5 is separated from the dust outlet 12, and the influence of dust from the dust outlet 12 is small.

[0048] In one embodiment, as shown in FIGS. 3, 5 to 7, 13, 15 and 17, the elastic member 5 is located at one end separated from the cover body 42 of the restraint member 41. One end of the elastic member 5 contacts the restraint member 41, and the other end of the elastic member 5 contacts the guide member 2. The elastic member 5 is used to drive the restraint member 41 to move toward the dust outlet 12 so that the cover body 42 closes the dust outlet 12. With such a structure, the elastic member 5 is located at one end separated from the cover body 42 of the restraint member 41, and the elastic member 5 is used to drive the restraint member 41 to move toward the dust outlet 12 so that the cover body 42 closes the dust outlet 12. The cup body 1 and the guide member 2 can move relative to the restraint member 41 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 the guide member 2 is removed, the restraint member 41 moves toward the dust outlet 12 by the elastic force of the elastic member 5 and drives the cover body 42 to close the dust outlet 12.

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

[0050] As can be understood, the position of the elastic member 5 is not limited to one end separated from the dust outlet 12 in the first direction of the dust cover 4, and the elastic member 5 may be provided at other positions as required. Exemplarily, the elastic member 5 may be located at one end on the dust outlet 12 side in the first direction of the dust cover 1.

[0051] Exemplarily, when the elastic member 5 is located at one end on the dust outlet 12 side in the first direction of the dust cover 4, the elastic member 5 is in a tension 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 by 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 at one end of the guide member 2 away from the dust outlet 12 in the first direction, and the guide member 2 hooks the other end of the elastic member 5 by the second hook so that the other end of the elastic member 5 contacts the guide member 2.

[0055] In one embodiment, a third hook is formed on the cup body 1 at one end of the elastic member 5 away from the dust cover 4, and the cup body 1 hooks the other end of the elastic member 5 by 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 may not be provided with the elastic member 5, and the dust cover 4 is automatically closed by gravity or manually closed.

[0057] In one embodiment, as shown in FIGS. 6 and 7, the shape of the cup body 1 is cylindrical, 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] Exemplarily, when the cup body 1 and the side wall 13 are connected, during the process of the dust outlet 12 of the cup body 1 opening to discharge dust, the axial direction of the cup body 1 is arranged substantially along the vertical direction.

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

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

[0061] In one embodiment, as shown in FIGS. 6 and 7, the length of the cup body 1 in the axial direction of the cup body 1 is greater than the diameter of the cup body 1. By configuring it in this way, the arrangement direction of the guide member 2 and the dust discharge port 12 is almost close to the axial direction of the cup body 1. The cup body 1 is longer than its length in the axial direction, and there is sufficient space for arranging the guide member 2 and the dust cover 4 in the axial direction of the side wall 13 of the cup body 1.

[0062] Note that the side wall 13 of the cup body 1 means the wall of the cup body 1 surrounding the circumference of the central axis of the cup body 1.

[0063] In one embodiment, as shown in FIGS. 6, 7, and 8, one end of the cup body 1 in the axial direction of the cup body 1 is the first end, the other end of the cup body 1 in the axial direction of the cup body 1 is the second end, and the distance between the dust discharge port 12 and the end face of the first end of the cup body 1 is greater than the distance between the dust discharge port 12 and the end face of the second end of the cup body 1, and the guide member 2 is located between the dust discharge port 12 and the end face of the first end of the cup body 1. By structuring it in this way, the length between the guide member 2 and the end face of the first end is long, and with sufficient space, the dust cover 4 is guided to move along the first direction.

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

[0065] In one embodiment, the shape of the cup body 1 is cylindrical, the dust discharge port 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 intersecting the axial direction of the cup body 1.

[0066] Exemplarily, when the guide member 2 is connected to the end wall 14 of the cup body 1, in the process of the dust discharge port 12 of the cup body 1 opening to discharge dust, the axial direction of the cup body 1 is arranged in a substantially horizontal direction, and the first direction is arranged along a substantially vertical direction.

[0067] Note that 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 a plane.

[0069] In one embodiment, the included angle between the first direction and the axial direction of the cup body 1 is large, and the first direction is close to being 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 FIGS. 6, 7, 13, 15, and 17, the first direction may be arranged along the vertical direction. By configuring in this way, it is easy for the dust cover 4 to open and close the dust discharge port 12.

[0072] In one embodiment, as shown in FIGS. 5, 7, 8, 13, 15, and 17, the bottom wall of the dust discharge port 12 protrudes from the cup body 1 along the dust discharge direction of the dust discharge port 12. By configuring in this way, the bottom of the dust discharge port 12 can extend toward the dust collection port 402 and discharge dust well, and dust leakage such as dust from the bottom of the dust discharge port 12 can be reduced.

[0073] An embodiment of the present invention provides a vacuum cleaner 300. As shown in FIGS. 1, 2, 4, 11, 12, 14, and 16, the vacuum cleaner 300 includes a main body 200 of the vacuum cleaner and the dust cup 100 of any of the above embodiments, and the cup body 1 is attached to the main body 200 of the vacuum cleaner. By configuring in this way, the main body 200 of the vacuum cleaner sucks dust such as dirt on the surface of the object to be cleaned, and the dust such as dirt is sucked into the first dust collection chamber 11 of the dust cup 100.

[0074] Embodiments of the present invention provide a dust collection system. As shown in FIGS. 1, 10, 11, 12, 14, and 16, the dust collection system includes a base station 400 in which a second dust collection chamber 401 communicating with each other and a dust collection port 402 are formed. By configuring in this way, the second dust collection chamber 401 of the base station 400 collects dust and other garbage 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 main body of the vacuum cleaner.

[0076] As an example, as shown in FIGS. 1, 2, 4, 11, 12, 14, and 16, the dust collection system further includes the vacuum cleaner 300 of any of the above embodiments or the dust cup 100 of any of the above embodiments.

[0077] In one embodiment, as shown in FIGS. 13, 15, and 17, when the base station 400 abuts against the dust cover 4, the dust cover 4 can open the dust outlet 12 under the action of the base station 400, and at least a part of the opened dust outlet 12 is located within the dust collection port 402 such that the dust outlet 12 communicates with the dust collection port 402. With such a configuration, when it is necessary to discharge dust and other debris in the first dust collection chamber 11, when the dust cover 4 is abutted against the base station 400, the dust cover 4 opens the dust outlet 12 under the action of the base station 400. Since at least a part of the opened dust outlet 12 is located within the dust collection port 402 such that the dust outlet 12 communicates with the dust collection port 402, dust and other debris in 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. Thereby, dust and other debris in the first dust collection chamber 11 are discharged into the second dust collection chamber 401 of the base station 400, reducing the degree of dust generation during the process of discharging dust and other debris from the first dust collection chamber 11, and improving the user experience. Since the dust cover 4 opens the dust outlet 12 under the action of the base station 400, the user's involvement in the process of opening the dust outlet 12 can be reduced, the operation can be simplified, the user's labor intensity can be lowered, and the user experience can be improved.

[0078] Note that the pipe communicating with the dust collection port 402 in the base station 400 belongs to the second dust collection chamber 401.

[0079] Exemplarily, the first direction is arranged along the vertical direction, the dust cover 4 abuts against 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] Exemplarily, the first direction is arranged along the vertical direction, the dust cover 4 abuts against the base station 400, the cup body 1 does not move, and the base station 400 drives the dust cover 4 to move upward to open the dust outlet 12.

[0081] Exemplarily, the first direction is arranged along the vertical direction, the guide member 2 is located above the dust discharge port 12, and when it is necessary to discharge dust and other garbage in the first dust collection chamber 11, the user holds the vacuum cleaner 300 and moves the dust cup 100 from top to bottom relative to the base station 400, and abuts the dust cover 4 against the base station 400. When the user holds the vacuum cleaner 300 and subsequently moves the cup body 1 of the dust cup 100 downward to open the dust discharge port 12 in the dust cover 4, the dust and other garbage in the first dust collection chamber 11 are discharged into the second dust collection chamber 401 through the dust discharge port 12 and the dust collection port 402. When the dust discharge in the first dust collection chamber 11 is completed, the user holds the vacuum cleaner 300 and lifts it away from the base station 400.

[0082] Exemplarily, the first direction is arranged along the vertical direction, the guide member 2 is located above the dust discharge port 12, and when it is necessary to discharge dust and other garbage in the first dust collection chamber 11, the dust cup 100 can be removed from the vacuum cleaner 300. The user can move the removed dust cup 100 from top to bottom relative to the base station 400 and abut the dust cover 4 against the base station 400. When the user subsequently moves the cup body 1 of the dust cup 100 downward to open the dust discharge port 12 in the dust cover 4, the dust and other garbage in the first dust collection chamber 11 are discharged into the second dust collection chamber 401 through the dust discharge port 12 and the dust collection port 402. When the dust discharge in the first dust collection chamber 11 is completed, the user lifts the dust cup 100 away from the base station 400.

[0083] As can be understood, the dust cup 100 further includes an elastic member 5, and the elastic member 5 is used to drive the restraint member 41 to move toward the dust discharge port 12 and close the dust discharge port 12 on the cover body 42. When the user lifts the vacuum cleaner 300 or the dust cup 100, the dust cover 4 automatically closes the dust discharge port 12 by the elastic force of the spring.

[0084] In one embodiment, at least a part 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 in the dust collection port 402 so as to communicate the dust discharge port 12 with the dust collection port 402.

[0086] Note that at least a part of the open dust discharge port 12 being located in the dust collection port 402 means that at least a part of the projection area of the dust discharge port 12 is located within the projection area of the dust collection port 402 in the dust discharge direction of the dust discharge port 12.

[0087] Note that the open dust discharge port 12 being located in the dust collection port 402 means that the projection area of the dust discharge port 12 is located within the dust collection port 402 in the dust discharge direction of the dust discharge port 12.

[0088] In one embodiment, as shown in FIGS. 3, 5 to 8, 13, 15 and 17, an avoidance groove 21 is formed on the side of the guide member 2 away from the cup body 1, a boss 43 penetrating the avoidance groove 21 is formed on the dust cover 4, and the base station 400 has an operating portion 403 for the boss 43 to abut against. By configuring in this way, when the operating portion 403 of the base station 400 abuts against the boss 43, the dust cover 4 can be easily opened at the dust discharge port 12.

[0089] In one embodiment, as shown in FIGS. 3, 5 to 8, 13, 15 and 17, the avoidance groove 21 is arranged to guide the guide member 2 to move along the extending direction of the avoidance groove 21 of the boss 43. The avoidance groove 21 plays a guiding role to a certain extent and abuts against the boss 43 of the dust cover 4 via the operating portion 403 of the base station 400.

[0090] As can be understood, the boss 43 penetrates the avoidance groove 21 of the guide member 2, the position of the boss 43 is far from the dust discharge port 12, and the base station 400 needs to ensure sufficient space on the dust collection port 402 side of the operating portion 403 to avoid the cup body 1 moving with respect to the dust cover 4.

[0091] In one embodiment, the operating part 403 protrudes from the base station 400 on the side away from the dust collection port 402. By configuring it in this way, since the operating part 403 protrudes from the base station 400 on the side away from the dust collection port 402, the base station 400 can have sufficient space to accommodate the cup body 1 that moves with respect to the dust cover 4 on the dust collection port 402 side of the operating part 403, and it is advantageous for discharging dust and the like in the first dust collection chamber 11 due to a sufficient opening of the dust discharge port 12.

[0092] In one embodiment, as shown in FIGS. 10, 13, 15, and 17, the first direction is arranged along the vertical direction, and the operating part 403 is located above the dust collection port 402. By configuring it in this way, in the process of placing the vacuum cleaner 300 or the dust cup 100 on the base station 400 to discharge dust, since the dust cup 100 is placed on the base station 400 from top to bottom, the base station 400 can abut against the lower side of the dust cover 4 and move the dust cover 4 substantially upward to open the dust discharge port 12. In the process of placing the vacuum cleaner 300 or the dust cup 100 on the base station 400 from top to bottom, since the operating part 403 is located above the dust collection port 402, it is advantageous to abut the dust cover 4 against the base station 400 when the dust cover 4 has not yet blocked the dust collection port 402 or before the dust cover 4 slightly blocks the dust collection port 402, and it can reduce the risk that the base station 400 or the dust cup 100 interferes with the dust collection port 402 at the position where the base station 400 and the dust cup 100 abut, and the degree of interference of the dust cover 4 with the dust collection port 402, and can reduce the space occupation on both sides of the dust collection port 402. Since the operating part 403 is located above the dust collection port 402, in the process of placing the dust collection device on the base station 400 from top to bottom, the part of the dust cover 4 for abutting against 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 evenly and move smoothly with respect to the main body 200 of the vacuum cleaner.

[0093] In one embodiment, as shown in FIGS. 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 FIGS. 6 and 10, guide portions 22 are respectively formed on both opposing sides of the guide member 2 in the third direction, and the guide portions 22 are separated from the guide chamber 3. A guide groove 404 is formed in the base station 400, and guide grooves 404 are respectively provided on both opposing sides of the dust collection port 402. When the guide portion 22 is located within the guide groove 404, the guide groove 404 is arranged to extend in the first direction while one guide groove 404 opens towards the other guide groove 404. In this way, the guide portion 22 of the guide member 2 is inserted into the guide groove 404, and the base station 400 guides the moving direction of the guide portion 22 within the guide groove 404 and guides the moving direction of the dust cup 100. Since one guide groove 404 opens towards the other guide groove 404 and no opening is provided in the guide groove 404 in the receiving direction of the dust collection port 402, the guide portion 22 of the guide member 2 can be restrained, preventing the dust cup 100 from detaching from the base station 400 during the process of moving and discharging dust.

[0095] As shown in FIGS. 6, 7, and 10, the receiving direction of the dust collection port 402 is arranged substantially along the second direction.

[0096] In one embodiment, as shown in FIGS. 12 to 17, the base station 400 is for abutting against the lower side of the dust cover 4. By doing so, the base station 400 opens the dust discharge port 12 by pushing the dust cover 4 substantially upward and moving it relative to the main body 200 of the vacuum cleaner.

[0097] In one embodiment, as shown in FIGS. 12 to 17, the base station 400 is for abutting against the lower side of the dust cover 4, and the first direction is arranged along the vertical direction.

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

[0099] In one embodiment, as shown in FIGS. 12 to 17, when the base station 400 abuts below 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 position and the lowest position of the dust collection port 402 in the vertical direction. With such a configuration, when the base station 400 abuts below 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 main body 200 of the vacuum cleaner moves downward, the base station 400 moves the dust cover 4 relative to the main body 200 of the vacuum cleaner so as to open the dust discharge port 12, and dust and other garbage discharged from the dust discharge port 12 can enter the second dust collection chamber 401 through the dust collection port 402 that is not completely blocked by the dust cover 4 in the vertical direction.

[0100] In one embodiment, as shown in FIGS. 12 to 17, when the base station 400 abuts below 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 such a configuration, when the base station 400 abuts below the dust cover 4 and the dust discharge port 12 moves downward and is exposed from the dust cover 4, the highest position of the dust discharge when the dust discharge port 12 is exposed is approximately at the lowest position of the dust cover 4. Since the lowest position of the dust cover 4 is lower than the highest position of the dust collection port 402, dust and other garbage discharged from the dust discharge port 12 do not rise above the highest position of the dust collection port 402, and when 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 garbage can be well received by the dust collection port 402, and the degree of dust generation during the process of discharging dust and other garbage can be reduced.

[0101] In one embodiment, as shown in FIGS. 12 to 17, when the base station 400 abuts against the dust cover 4 and moves the dust cover 4 relative to the main body 200 of the cleaner 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. Thereby, the dust collection port 402 can favorably receive dust and other debris discharged from the dust outlet 12, which is advantageous for reducing the degree of dust generation.
