[0047] As shown in FIG. 6, the dust cup flip cover 130 is in the closed state, and the dust cup assembly 100 is placed on the dust cup carrier 310. Figure 1 In this embodiment, the lock catch assembly 140 has a default state of the locked state when no external force is applied. At this time, the lock catch assembly 140 locks the dust cup flip cover 130 in the closed state. Figure 5 A cross-sectional view of the dust cup assembly of an embodiment of the present application in the unlocked state is shown. As shown in FIG. 7, the dust cup flip cover 130 is in the open state. Figure 5 In the state that the dust cup assembly 100 is placed on the dust cup carrier 310, the dust collection matching member 311, which is the external matching member, passes through the second opening 122 to switch the lock catch assembly 140 to the unlocked state, and the dust cup flip cover 130 changes to the open state.

[0048] According to the dust cup assembly 100, the dust cup bottom cover 120 has a first opening 121 communicated with the first dust collecting bin 119, a second opening 122 located at one side of the first opening 121, and an inner side of the dust cup bottom cover 120 facing the first dust collecting bin 119. The lock catch assembly 140 is installed on the inner side of the dust cup bottom cover 120, that is, the lock catch assembly 140 is basically covered by the dust cup bottom cover 120, instead of being exposed on the surface of the dust cup assembly 100. On the one hand, the lock catch assembly 140 is prevented from being unlocked due to external knocking, and the dust cup cover 130 is prevented from being opened by mistake, so that the stability of the lock catch assembly 140 is ensured. On the other hand, the lock catch assembly 140 is prevented from being covered with dust due to external exposure, and the lock catch assembly 140 is prevented from being stuck due to the dust, so that the use reliability and the use smoothness of the dust cup assembly 100 are improved. When the lock catch assembly 140 needs to be unlocked, the external matching part passing through the second opening 122 can unlock the lock catch assembly 140, so that the dust cup assembly 100 is smoothly collected to the base station, the lock catch assembly 140 is hidden in the inner side of the dust cup bottom cover 120, the integrity of the outer surface of the dust cup assembly 100 is improved, and the assembly of the dust cup assembly 100 and the dust collector main machine is facilitated.

[0049] As Figure 1 , Figure 2 In some embodiments, the dust cup assembly 100 further comprises a rotating shaft 150 and a reset member 160. The dust cup cover 130 is connected with the dust cup bottom cover 120 and / or the cup body 110 through the rotating shaft 150, so that the dust cup cover 130 can rotate relative to the dust cup bottom cover 120. The reset member 160, for example, is a torsion spring, and can also be other elastic structures. The reset member 160 is connected with the dust cup cover 130, and is used for resetting the dust cup cover 130 to a closed state. In the embodiment, the rotating shaft 150 and the reset member 160 are located on the inner side of the dust cup bottom cover 120.

[0050] In the embodiment, the lock catch assembly 140 is arranged opposite to the rotating shaft 150. The lock catch assembly 140 is located on one side of the first opening 121, and the rotating shaft 150 is located on the other side of the first opening 121.

[0051] As Figure 1 , Figure 2 In some embodiments, the cup body 110 comprises a dust collecting main body part 111 and a dust guiding part 112. The dust guiding part 112 is located between the dust collecting main body part 111 and the dust cup bottom cover 120. The size of the first opening 121 is smaller than the cross-sectional size of the inner cavity of the dust collecting main body part 111. At least part of the wall surface of the dust guiding part 112 is arranged to be inclined relative to the dust cup bottom cover 120. The cross-sectional size of the inner cavity of the dust guiding part 112 gradually decreases in the direction away from the dust collecting main body part 111.

[0052] In the above embodiment, the cup body 110 comprises a dust guide portion 112, at least part of the wall surface of the dust guide portion 112 is arranged obliquely relative to the dust cup bottom cover 120, and the cross-sectional dimension of the inner cavity of the dust guide portion 112 gradually decreases in the direction away from the dust collection main body portion 111. When the dust cup assembly 100 is collecting dust to the base station, the oblique structure of the dust guide portion 112 can guide the flow of dust, and reduce the possibility of dust accumulation in the corner of the dust cup bottom.

[0053] In some embodiments, the cup body 110 further comprises an extension portion 113, which extends between the dust collection main body portion 111 and the dust cup bottom cover 120, so that the inner wall of the extension portion 113, the outer wall of the dust guide portion 112 and the inner side of the dust cup bottom cover 120 jointly enclose a mounting space Z1, and the lock catch assembly 140 is mounted in the mounting space Z1.

[0054] In the above embodiment, due to the oblique arrangement of the dust guide portion 112, the mounting space Z1 can be formed between the outer wall of the dust guide portion 112 and the inner side of the dust cup bottom cover 120, and the lock catch assembly 140 is mounted in the mounting space Z1. On the one hand, this makes the arrangement of components of the dust cup assembly 100 more compact and the space utilization rate higher. On the other hand, the lock catch assembly is built-in in the mounting space Z1, which can avoid the problem that the lock catch assembly 140 is easy to accumulate dust due to being exposed, and reduce the situation that the lock catch assembly 140 is stuck due to dust accumulation.

[0055] In some embodiments, the rotating shaft 150 and the reset member 160 of the dust cup assembly 100 are located in the mounting space Z1, which also makes the arrangement of components of the dust cup assembly 100 more compact and the space utilization rate higher, and the dust cup bottom cover 120 can provide protection for the rotating shaft 150.

[0057] The first elastic member 142 is, for example, a spring, and in other embodiments, it can also be a spring piece, a rubber elastic body, etc.

[0058] In the embodiment, the locking assembly 140 is located at the outer peripheral side of the first opening 121. When the locking assembly 140 is not subjected to the force of the external cooperating member, the first elastic member 142 causes the sliding lock 141 to slide towards the first opening 121, so as to abut against the dust cup cover 130 and lock the dust cup cover 130. When the locking assembly 140 is subjected to the force of the external cooperating member, the external cooperating member pushes the sliding lock 141 away from the first opening 121, so that the sliding lock 141 is separated from the dust cup cover 130, and the dust cup cover 130 is unlocked.

[0059] In some embodiments, the sliding lock 141 comprises a force receiving groove 1411 in communication with the second opening 122. The force receiving groove 1411 has a force receiving slope S1 inclined relative to the dust cup bottom cover 120. During the gradual insertion of the external cooperating member into the force receiving groove 1411, the external cooperating member is in sliding cooperation with the force receiving slope S1, so that the sliding lock 141 slides away from the dust cup cover 130.

[0060] In the above embodiment, by providing the force receiving slope S1 on the sliding lock 141, the smoothness of the pushing of the sliding lock 141 by the external cooperating member during the gradual insertion of the external cooperating member into the force receiving groove 1411 is improved, and the reliability of the unlocking of the sliding lock 141 is ensured.

[0061] In some embodiments, the dust cup cover 130 comprises an abutting groove 131, and the sliding lock 141 comprises an abutting portion 1412. The abutting portion 1412 abuts against the abutting groove 131, so that the locking assembly 140 locks the dust cup cover 130.

[0062] In the above embodiment, the dust cup cover 130 comprises the abutting groove 131, and the abutting portion 1412 of the sliding lock 141 can be inserted into the abutting groove 131, so as to lock the dust cup cover 130. After the locking, the freedom of the inward rotation and the outward rotation of the dust cup cover 130 around the shaft is locked, so as to ensure the position stability of the locking of the dust cup cover 130.

[0063] In some embodiments, the locking assembly 140 further comprises a locking mounting seat 143 connected with the cup body 110 and / or the dust cup bottom cover 120. The sliding lock 141 is mounted on the locking mounting seat 143. In the embodiment, the locking mounting seat 143 comprises a sliding track. The sliding lock 141 is mounted on the sliding track. The first elastic member 142 elastically abuts between the sliding lock 141 and the locking mounting seat 143.

[0064] In other embodiments, the abutting manner of the sliding lock 141 against the dust cup cover 130 to lock the dust cup cover 130 is not limited to the cooperation of the abutting groove 131 and the abutting portion 1412, but can be other abutting manners.

[0065] As Figure 1、 Figure 2 In some embodiments, the dust cup assembly 100 further comprises a limiting assembly 170. The limiting assembly 170 is mounted to the cup body 110 and at least partially located inside the dust cup bottom cover 120. The limiting assembly 170 is used to limit the cup body 110 and the machine body 210 when the dust cup assembly 100 and the machine body 210 of the main cleaner are mounted in place.

[0066] In some embodiments, the machine body 210 of the main cleaner has a dust cup track 211, and the dust cup assembly 100 can be mounted to the dust cup track 211 in an axial direction. Optionally, the dust cup track 211 of the machine body 210 is provided with a cooperating structure cooperating with the limiting assembly 170. When the dust cup assembly 100 is mounted to the machine body 210 of the main cleaner and mounted in place, the limiting assembly 170 cooperates with the cooperating structure, thereby limiting the dust cup assembly 100, stably connecting the dust cup assembly 100 and the machine body 210, and avoiding the dust cup assembly 100 from being accidentally detached. When it is necessary to detach the dust cup assembly 100 from the machine body 210, the limiting assembly 170 is unlocked, and the dust cup assembly 100 is taken out of the dust cup track 211.

[0067] As Figure 1 In some embodiments, the cup body 110 further comprises an extension 113 extending between the dust collection main body 111 and the dust cup bottom cover 120, so that the inner wall of the extension 113, the outer wall of the dust guide 112 and the inner side of the dust cup bottom cover 120 collectively enclose an installation space Z1, and the limiting assembly 170 is at least partially located in the installation space Z1, so that the components of the dust cup assembly 100 are more compactly arranged, and the space utilization is higher.

[0068] As Figure 2 、 Figure 3 In some embodiments, the dust cup bottom cover 120 further has a third opening 123 located on one side of the first opening 121.

[0069] Figure 7 It is a three-dimensional exploded view of the limiting assembly of an embodiment of the dust cup assembly of the utility model. In some embodiments, the limiting assembly 170 comprises a limiting piece 171 and a second elastic piece 172. The limiting piece 171 comprises a protruding part 1711 and a button part 1712. The second elastic piece 172 elastically connects the limiting piece 171 and the cup body 110. The button part 1712 is arranged through the third opening 123. When the dust cup assembly 100 and the machine body 210 of the main cleaner are mounted in place, the protruding part 1711 protrudes from the cup body 110 and cooperatively connects with the machine body 210.

[0070] In the embodiment, the second elastic member 172 is a spring which abuts between the limiting member 171 and the cup body 110 to apply an elastic force to the limiting member 171. The limiting member 171 is movably installed on the cup body 110, and / or the limiting member 171 can be elastically deformed, so that the switching between the limiting function and the non-limiting function can be realized. When the limiting member 171 is movably installed on the cup body 110, for example, the limiting member 171 can swing around one end of the limiting member 171. When the limiting member 171 can be elastically deformed, for example, the limiting member 171 can be bent.
