[0033] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a dust box 100 is provided. The dust box 100 includes a box body 10 and a compacting mechanism 20.

[0034] Among them, the box body 10 is provided with a accommodating chamber 101, and a dust suction port 102 connecting the external space of the box body 10 and the accommodating chamber 101 is provided on the side wall of the accommodating chamber 101; the compacting mechanism 20 includes a compacting member 21 and a driving assembly 22, the compacting member 21 is arranged in the accommodating chamber 101, and the driving assembly 22 is arranged outside the accommodating chamber 101 and is detachably connected to the compacting member 21 to drive the compacting member 21 to move in the accommodating chamber 101 to compact the garbage in the accommodating chamber 101.

[0035] When the dust box 100 of this embodiment is actually used, dust and other garbage can enter the accommodating chamber 101 from the dust suction port 102. However, the garbage entering the accommodating chamber 101 from the external environment through the dust suction port 102 is mostly randomly and fluffy in the accommodating chamber 101. When the garbage in the accommodating chamber 101 is full, the garbage in the dust box 100 needs to be dumped. In the present application, a compacting member 21 is provided in the accommodating chamber 101. After the garbage enters the accommodating chamber 101, the compacting member 21 is driven to move in the accommodating chamber 101 by the driving assembly 22. In this process, the compacting member 21 can push the garbage in the accommodating chamber 101 to move toward the inner wall surface of the accommodating chamber 101, and compact the fluffy garbage in the accommodating chamber 101, thereby improving the space utilization rate of the accommodating chamber 101.

[0036] That is to say, since a compacting member 21 is provided in the accommodating chamber 101 of the box body 10 in this embodiment, the compacting member 21 can move inside the accommodating chamber 101 under the drive of the driving component 22 to compact the garbage in the accommodating chamber 101, which can improve the space utilization rate of the accommodating chamber 101 in the box body 10, and facilitate more garbage to enter the accommodating chamber 101 from the dust suction port 102. When in use, the number of times the garbage in the dust box 100 is dumped can be reduced, which can improve the user experience and meet the user's usage needs.

[0037] At the same time, since the driving component 22 in this embodiment is arranged outside the box body 10, when the driving component 22 moves, it is not easily disturbed by garbage and the like in the accommodating cavity 101, and the operation is more stable and reliable.

[0038] Specifically, the box body 10 in this embodiment can be a prismatic box body, a cylindrical box body, an elliptical box body or other special-shaped box bodies, which is not specifically limited in this application. In order to facilitate taking and placing, a hand-held portion 14 is provided on the box body 10 in this embodiment, and the hand-held portion 14 can be a U-shaped handle, an O-shaped handle or an operating handle of other shapes, which is not specifically limited in this application.

[0039] In some embodiments of the present application, the box body 10 includes a shell 11 and a cover 12. The shell 11 is provided with a cavity 112, and the side wall of the cavity 112 is provided with the above-mentioned dust suction port 102, so that external dust can enter the cavity 112. The cover 12 has a first position where it is covered on the shell 11 and surrounded with the cavity 112 to form an accommodating cavity 101, and a second position where it moves to the outside of the shell 11 to open the cavity 112.

[0040] When the cover 12 is placed on the housing 11 and is in the first position, the cavity 112 can be covered to prevent dust and other garbage from leaking from the notch of the cavity 112. When the cover 12 moves to the outside of the housing 11 and is in the second position, the garbage in the cavity 112 can be dumped from the cavity 112.

[0041] During actual assembly, the cover body 12 and the shell body 11 in this embodiment can be fixedly connected by a snap fastener, or can be rotatably connected by a shaft or hinge, or can be connected by a combination of snap fasteners, a shaft or a hinge, etc., as long as the cover body 12 can be switched between the first position and the second position. No specific limitation is made in this application.

[0042] When in use, the dust box 100 in this embodiment can be installed on a cleaning device, such as a sweeping robot. After the dust box 100 is installed, the dust box 100 can be located on the top of the cleaning device. When the dust box 100 needs to be removed from a cleaning device such as a sweeping robot, it is only necessary to pull the dust box 100 upwards. At this time, the dust box 100 is subjected to an upward pulling force, and the main structure of the cleaning device such as the sweeping robot is subjected to its own gravity. The force directions of the dust box 100 and the cleaning device are exactly opposite, so the dust box 100 can be removed from the cleaning device more easily.

[0043] In addition, when the dust box 100 is taken out from the cleaning device, the cover 12 of the dust box 100 is located at the bottom. At this time, it is only necessary to press the buckle used to lock the cover 12, and the cover 12 can be opened downward under its own weight, and the garbage in the dust box 100 can fall directly from the opening of the shell 11 into the garbage recycling station under its own weight. In other words, when dumping garbage, the user only needs to pull the dust box 100 upward, then translate the dust box 100 to the garbage recycling station, and then press the buckle that fixes the cover 12, so that the garbage can be dumped conveniently. The entire garbage dumping process does not require the dust box 100 to be turned over, which is convenient to use and saves time and effort.

[0044] It is understandable that the timing of dumping the garbage in this embodiment can be designed and selected according to the needs of the user. For example, the user can dump the garbage by himself after observing that the garbage in the dust box 100 has reached a certain amount. Of course, in this application, it is also possible to use a method of setting a corresponding detection element (infrared sensor, weight sensor and other structures) in the dust box 100 to detect the amount of garbage in the dust box 100, and then prompt the user to dump the garbage. As long as it is other deformation methods under the concept of this application, it is not specifically limited in this application.

[0045] It is understandable that, when the dust box 100 is actually used, the dust box 100 can also be located at other positions of the cleaning device, and is not limited to the top of the cleaning device.

[0046] Furthermore, in order to suck external dust into the accommodating chamber 101 of the box body 10, a suction channel 13 is further provided on the box body 10 in the present application. The suction channel 13 can be provided on the shell 11, or on the cover 12, or at the junction of the shell 11 and the cover 12. The drawings of the present application show the situation when the suction channel 13 is provided at the bottom of the shell 11. When the dust box 100 in the present embodiment is actually used, the suction channel 13 can be connected to the vacuum pump of the vacuum pump. In this way, when the vacuum pump is working, the accommodating chamber 101 can be in a negative pressure state, so that dust, hair and other garbage in the external environment can be sucked into the accommodating chamber 101 from the dust suction port 102. Optionally, a filter 131 is provided at the entrance of the suction channel 13 in the present embodiment. Through the function of the filter 131, dust in the accommodating chamber 101 can be prevented from entering the vacuum pump and other structures to damage the vacuum pump.

[0047] In some embodiments of the present application, in order to facilitate the compaction of the garbage in the accommodating chamber 101, the compacting member 21 is arranged in the accommodating chamber 101 in a translatable manner. It can be understood that the translatable compacting member 21 described here can be, for example, a moving mode in which the compacting member 21 as a whole is moved from one side of the accommodating chamber 101 to the other side. In this structure, the compacting member 21 can be arranged as a compacting plate or a compacting sheet, and correspondingly, the driving component 22 can be arranged as a structure such as a driving cylinder, and the piston rod of the driving cylinder can be extended and retracted to drive the compacting plate or the compacting sheet to move in the accommodating chamber 101 to compact the garbage in the accommodating chamber 101.

[0048] See also Figures 4 to 6 As shown, in some embodiments of the present application, in order to facilitate the compaction of the garbage in the accommodating chamber 101, the compacting member 21 can also be rotatably arranged in the accommodating chamber 101, and the compacting member 21 is driven to rotate by the driving assembly 22, so that the garbage in the accommodating chamber 101 can be compacted.

[0049] Furthermore, in order to install and position the compacting member 21, a limiting column 121 is convexly provided on the inner wall surface of the accommodating chamber 101 in this embodiment, and the compacting member 21 includes a sleeve portion 211 and a compacting sheet 212, one end of the compacting sheet 212 is connected to the sleeve portion 211, and the sleeve portion 211 is rotatably sleeved on the limiting column 121. In this way, when the sleeve portion 211 rotates relative to the limiting column 121, the compacting sheet 212 can be driven to rotate or swing around the limiting column 121. During the rotation or swinging of the compacting sheet 212, the garbage in the accommodating chamber 101 can be compacted, thereby improving the space utilization rate of the dust box 100 in this embodiment.

[0050] Optionally, in this embodiment, the accommodating chamber 101 has a first side wall 1011, and the dust suction port 102 is arranged on the first side wall 1011. The projection of the limiting column 121 on the first side wall 1011 is at least partially located in the dust suction port 102. In this way, when the compacting member 21 rotates, the rotation center can be located as far in front of the dust suction port 102 as possible. During the rotation or swinging of the compacting member 21, the garbage in front of the dust suction port 102 can be effectively compacted or the garbage in front of the dust suction port 102 can be pushed away, which can effectively avoid the accumulation of garbage in front of the dust suction port 102 and prevent the dust suction port 102 from being blocked.

[0051] Exemplarily, the projection of the limiting column 121 in this embodiment on the first side wall 1011 is located at the center of the suction port 102 .

[0052] Furthermore, the compacting sheet 212 in this embodiment includes a hard body 2121 and a flexible portion 2122, and the flexible portion 2122 is coated on at least one side of the hard body 2121. In this way, when the compacting sheet 212 moves in the accommodating chamber 101, it can be prevented from scratching the inner wall surface of the accommodating chamber 101, and the service life of the dust box 100 in this embodiment can be improved to a certain extent. In some usage scenarios, such as when the dust box 100 is vacuuming, when the compacting member 21 rotates in the dust box 100, the flexible portion 2122 can move synchronously with the hard body 2121 to scrape the inner wall surface of the accommodating chamber 101, which can not only clean the stubborn stains attached to the inner wall surface of the accommodating chamber 101, but also facilitate the synchronous compaction of the garbage in the accommodating chamber 101.

[0053] In other usage scenarios, for example, when only the dust box 100 needs to be cleaned, the compacting member 21 can be driven to rotate manually or by using the driving assembly 22. At this time, the flexible portion 2122 rotates in the accommodating cavity 101 of the dust box 100, and the inner wall of the accommodating cavity 101 can be wiped, thereby facilitating automatic cleaning of the dust box 100.

[0054] For example, the hard body 2121 in this embodiment can be a structure such as a plastic sheet or a metal sheet. The flexible portion 2122 can be rubber, silicone, or flexible cotton cloth. In actual preparation, the hard body 2121 and the flexible portion 2122 can be integrally formed, or can be separately processed and fixed together by means of a locking member, welding, or bonding, etc., which is not specifically limited in this application.

[0055] In this embodiment, the compacting sheet 212 is connected to the sleeve portion 211 and extends radially along the sleeve portion 211. During actual processing, the compacting sheet 212 can be integrally formed with the sleeve portion 211, or it can be separately provided and then fixedly connected by structures such as snaps or locking screws. When the compacting sheet 212 and the sleeve portion 211 are integrally formed, the two can be connected as a whole by welding or injection molding. The compacting sheet 212 extends radially along the sleeve portion 211 and is provided in a long strip shape. The long strip compacting sheet 212 is a rectangular sheet structure. The flexible portion 2122 can be coated on both sides of the compacting sheet 212 in the length direction, or it can be coated on the side of the compacting sheet 212 away from the sleeve portion 211, or it can be coated on all outer sides or outer surfaces of the compacting sheet 212 at the same time.

[0056] Combination Figures 4 to 9 As shown, the compaction sheet 212 is a long strip, the width of which is consistent with the length of the sleeve portion 211, and the maximum length of the compaction sheet 212 along the radial direction of the sleeve portion 211 is L1, L1≤T, wherein T is the length of the compaction sheet 212 when the end of the compaction sheet 212 away from the sleeve portion 211 just interferes with or is just tangent to the inner wall surface of the accommodating cavity 101. Optionally, the length L1 is 60mm to 130mm, for example, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm or 130mm, etc. By setting the maximum length of the compaction sheet 212 along the radial direction of the sleeve portion 211 to 60mm to 130mm, it is not only convenient to compact the garbage in the accommodating cavity 101, but also can be adapted to the dust box 100 used by most cleaning devices such as sweeping robots.

[0057] Optionally, the maximum width of the compacting sheet 212 along the length direction of the sleeve portion 211 is L2, L2≤D, where D is the vertical width of the compacting sheet 212 (here the vertical direction is Figure 4 The width of the compacting sheet 212 when the two sides (in the H direction) just contact the upper and lower side walls of the accommodating cavity 101. Optionally, the maximum width L2 is 20 mm to 100 mm, such as 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm or 100 mm, etc. By setting the maximum width L2 of the compacting sheet 212 along the length direction of the sleeve 211 to 20 mm to 100 mm, it is easy to adapt to the size of the dust box 100 of most sweeping robots.

[0058] It is understandable that the length and width of the compacting sheet 212 of the present application can be adjusted according to the actual structure, and is not limited to the scope of protection claimed in the present application. During actual processing, the shape of the compacting sheet 212 can also be adjusted according to specific usage requirements, and is not limited to the long strip shape described in the present application.

[0059] In this embodiment, the compacting piece 212 moves in the accommodating chamber 101 in a reciprocating swinging manner, and the limiting column 121 is arranged on the side of the accommodating chamber 101 away from the first side wall 1011. Specifically, in this embodiment, the limiting column 121 is arranged on the side of the cover 12 opposite to the dust suction port 102, so that the compacting piece 212 can swing between the limiting column 121 and the dust suction port 102, and it is not easy to cause blockage of the dust suction port 102, and it is convenient to fully compact the garbage in the accommodating chamber 101 toward both sides of the dust suction port 102. Optionally, the maximum swinging angle of the compacting piece 212 in this embodiment is not less than 120°, such as 120°, 150°, 180°, 210°, 240°, 270°, 300°, 330° or 360°, etc. It can be understood that the maximum swinging angle mentioned here refers to the maximum rotation range of the compacting piece 21 in the accommodating chamber 101. In this way, the garbage in the accommodating chamber 101 can be effectively compacted in the direction away from the suction port 102, which not only improves the space utilization of the accommodating chamber 101, but also avoids garbage blockage in front of the suction port 102, making it easier to suck dust, hair, etc. from the external environment into the accommodating chamber 101.

[0060] In other embodiments of the present application, the limiting column 121 can also be set in the center of the accommodating chamber 101. In this case, the compacting member 21 can achieve 360° rotation while ensuring that the compacting sheet 212 does not interfere with other structures. Of course, in other embodiments of the present application, the limiting column 121 can also be set close to other side walls of the accommodating chamber 101, as long as the compacting member 21 can compact the garbage in the accommodating chamber 101 when rotating.

[0061] Furthermore, when the compacting sheet 212 swings, the end of the compacting sheet 212 away from the sleeve portion 211 has a predetermined gap or is tangent to the outer peripheral side wall of the accommodating cavity 101, so that the compacting sheet 212 can be prevented from interfering with the outer peripheral side wall of the accommodating cavity 101.

[0062] Furthermore, the hard body 2121 in the present embodiment is provided with a reinforcing rib 21211, and through the function of the reinforcing rib 21211, the structural strength of the hard body 2121 in the present embodiment can be improved, and the compaction ability and service life of the compacting member 21 can be improved. Optionally, the reinforcing rib 21211 in the present embodiment can be provided on one side or both sides of the hard body 2121. The reinforcing rib 21211 can be provided as one, or as two or more. The reinforcing rib 21211 can extend along the length direction of the hard body 2121, or along the width direction of the hard body 2121, or can be staggered along the length and width direction of the hard body 2121 to form a grid-like structure. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0063] Furthermore, the sleeve portion 211 in this embodiment includes a barrel 2111, an inserting portion 2113 is provided at the end of the barrel 2111, a through hole 122 is provided on the limiting column 121, and the through hole 122 is provided along the length direction of the limiting column 121. When installed, the inserting portion 2113 is inserted into the through hole 122, and the driving component 22 is at least partially provided in the through hole 122 and connected to the inserting portion 2113. When the driving component 22 is working, it can drive the inserting portion 2113 to rotate, and then drive the barrel 2111 and the compacting sheet 212 to rotate around the limiting column 121, and finally the purpose of compacting the garbage in the dust box 100 can be achieved.

[0064] Furthermore, the sleeve portion 211 in this embodiment further includes a sealing cover 2112, which is disposed at the first end of the cylinder 2111 and is surrounded with the cylinder 2111 to form a blind hole 2114, and the plug-in portion 2113 described above is disposed on one side of the sealing cover 2112 close to the blind hole 2114. During actual installation, the limit column 121 is inserted into the blind hole 2114, and the plug-in portion 2113 on the sealing cover 2112 is inserted into the through hole 122 and connected to the drive assembly 22, so that dust and the like in the accommodating chamber 101 is not easy to enter the through hole 122 from one end of the through hole 122 close to the plug-in portion 2113 to cause adverse effects on the movement of the drive assembly 22. Optionally, the sealing cover 2112 and the cylinder 2111 in this embodiment can be integrally formed, or they can be separately arranged and then connected together through welding, screws, snaps or other structural seals. As long as they are other deformation methods based on the conception of this application, they are within the protection scope of this application.

[0065] Furthermore, a sealing element 30 is provided between the inner wall surface of the cylinder 2111 and the outer peripheral surface of the limiting column 121 in this embodiment. Through the action of the sealing element 30 and the sealing cover 2112, it is possible to effectively prevent the dust and other garbage inside the accommodating chamber 101 from entering the through hole 122 and causing damage to the drive assembly 22. At the same time, through the action of the sealing ring, the sealing performance of the accommodating chamber 101 of the box body 10 can be ensured. When the vacuum device is working, the negative pressure characteristics of the accommodating chamber 101 can be ensured, which is convenient for suction of dust and the like, and also convenient for water cleaning of the accommodating chamber 101 inside the dust box 100. In addition, the setting of the sealing ring can also prevent the water and the like in the accommodating chamber 101 from leaking to the drive assembly 22 to damage the electrical components in the drive assembly 22.

[0066] Optionally, the sealing element 30 in this embodiment includes a sealing ring. The sealing ring may be one, two or more. When the sealing ring is provided in plurality, the plurality of sealing rings are sequentially arranged at intervals along the length direction of the limiting column 121, so that multi-stage sealing can be achieved. During actual installation, the sealing ring may be located at both ends of the cylinder 2111, or between the two ends of the cylinder 2111, which is not specifically limited in this application.

[0067] In order to prevent the compacting member 21 from being separated from the limiting column 121, a stopper 123 is provided on the inner wall of the through hole 122 in this embodiment, and correspondingly, a stopper 21133 is provided on the plug-in portion 2113, and the stopper 21133 is mounted on the stopper 123 and can rotate relative to the stopper 123. In this way, the plug-in portion 2113 can be prevented from falling off from the through hole 122 through the cooperation and limiting effect of the stopper 21133 and the stopper 123, and further, the compacting member 21 can be prevented from being separated from the limiting column 121. In addition, a limiting member 40 is provided between the stopper 21133 and the stopper 123, and through the effect of the limiting member 40, the stopper 21133 can be effectively limited to prevent the stopper 21133 from falling off from the through hole 122. There is a gap between the limiting member 40 and the locking portion 21133 and / or the stopping portion 123 to ensure that the sleeve portion 211 can rotate freely without interference.

[0068] Optionally, the plug-in portion 2113 in this embodiment is provided with an annular flange 21131, and at least one avoidance groove 21132 is provided on the circumference of the annular flange 21131. The outer wall surface of the annular flange 21131 is provided with the stop portion 21133, and the stop portion 21133 is a limit stop convex. Correspondingly, the stop portion 123 is a stop step. During actual installation, a pressing force is applied to the sleeve portion 211. At this time, the annular flange 21131 can shrink at the avoidance groove 21132 and be inserted into the through hole 122. As the annular flange 21131 is continuously inserted, the stop portion 21133 can be placed on the limit stop convex, which can limit the compacting member 21.

[0069] However, as the compacting piece 21 continues to swing or rotate, the compacting piece 21 will inevitably wear at the locking portion 21133. For this reason, the limiting piece 40 mentioned above is also provided in this embodiment. The limiting piece 40 may be a limiting plate 41. The limiting plate 41 is arranged in a ring shape and is made of a material with relatively high hardness. The limiting plate may be a metal plate, for example. The limiting piece 40 is sleeved on the outer periphery of the annular flange 21131 and is located between the locking portion 21133 and the stop portion 123. It can not only effectively prevent the plug-in portion 2113 from falling off from the through hole 122, but also play a role in preventing wear.

[0070] Furthermore, the drive assembly 22 in this embodiment includes a motor 221 and a reduction box 222. During actual installation, the drive assembly 22 in this embodiment is at least partially installed in the through hole 122, so that the external volume of the dust box 100 can be reduced, the miniaturized design of the dust box 100 can be realized, and the dust box 100 in this embodiment can be installed in a cleaning device such as a sweeping robot. At the same time, the drive assembly 22 in this embodiment is provided with a reduction box 222, and the swing speed of the compacting member 21 can be set according to actual needs. Of course, in other embodiments of the present application, the drive assembly 22 may not be provided with a reduction box 222, and any other deformation methods under the conception of the present application are within the protection scope of the present application.

[0071] Optionally, in this embodiment, the motor 221 and the reduction box 222 are both installed in the through hole 122, wherein the output shaft of the motor 221 is connected to the reduction box 222, and the reduction box 222 is provided with a drive shaft 2221, and the drive shaft 2221 is connected to the plug-in portion 2113 through a coupling 223. Specifically, one of the coupling 223 and the plug-in portion 2113 is provided with a plug-in protrusion 2231, and the other of the two is provided with a plug-in groove 21134 adapted to the plug-in protrusion 2231, and the coupling 223 and the plug-in portion 2113 are detachably connected through the plug-in protrusion 2231 and the plug-in groove 21134. That is to say, the drive assembly 22 in this embodiment is located as a whole outside the box body 10, and the plug-in portion 2113 and the coupling 223 are detachably connected through the plug-in protrusion 2231 and the plug-in groove 21134. When the dust box 100 in this embodiment is installed on other structures, such as a sweeping robot, the drive assembly 22 can be fixed on the main structure of the sweeping robot. In this way, when the dust box 100 is removed from the sweeping robot for maintenance and garbage dumping, the drive assembly 22 can be retained in the main structure of the sweeping robot, which can reduce the overall weight of the box body 10 and make it more convenient for users to use.

[0072] In addition, the plugging protrusion 2231 in this embodiment can be a bar-shaped or cross-shaped protrusion, and the plugging groove 21134 can be a bar-shaped groove or a cross-shaped groove. Figure 8The case where the plug-in groove 21134 is set as a strip groove is shown in the figure. In this way, when the coupling 223 rotates under the drive of the motor 221, the compacting member 21 can be driven to rotate around the limit column 121 to compact the garbage. In addition, when the drive component 22 and the compacting member 21 are actually assembled, the compacting member 21 and the coupling 223 can be blindly assembled, which has a simple structure and is easy to use. Of course, in other embodiments of the present application, in order to realize the blind assembly of the drive component 22 and the compacting member 21, an axial spring and a locking structure can be provided. As long as it is other deformation methods under the conception of the present application, they are all within the protection scope of the present application.

[0073] In order to facilitate fixing the driving assembly 22 in this embodiment to a predetermined structure, such as the main body of a sweeping robot, the dust box 100 in this embodiment is further provided with a connecting member 50, through which the driving assembly 22 is connected to the main body of the sweeping robot. Optionally, the connecting member 50 includes a connecting sleeve 51 and an annular outer flange 52. During actual installation, the connecting sleeve 51 is embedded in the through hole 122, and the driving assembly 22 is arranged in the connecting sleeve 51 and connected to the compacting member 21 through the connecting sleeve 51, so as to facilitate driving the compacting member 21 to rotate. The annular outer flange 52 is located outside the box body and stops at the port of the through hole 122, so as to facilitate the taking and placing of the connecting sleeve 51. During installation, the connecting member 50 can be fixed to the main body of the sweeping robot by means of a structure such as screws penetrating the annular outer flange 52.

[0074] In combination with the above embodiments, it can be known that:

[0075] The dust box 100 of the present application is powered by the motor 221 and the reduction gear box 222, and the power is transmitted by the coupling 223. The coupling 223 has the function of guiding and transmitting torque, which can enable the user to blindly assemble the dust box 100 and successfully dock and transmit torque. The compaction sheet 212 and the sleeve part 211 are the same component, and the axial freedom of the sleeve part 211 is limited by the stopper 21133. The stopper 21133 is assembled in the form of a limit clamp convex. At the same time, a limiter 40 is equipped to strengthen the limit. The limiter 40 is a metal sheet, which has the characteristics of wear resistance and low friction, and can improve the service life of the dust box 100 of the present application. A sealing ring is provided between the compaction piece 21 and the limit column 121 of the present application, which can improve the dustproof and waterproof and sealing properties of the dust box 100, thereby ensuring that the inside of the dust box 100 can be directly cleaned by water, and the air pressure is not easy to leak when the dust box is working. Flexible portions 2122 are designed around the compacting piece 21 to enhance the toughness and flexible deformability of the compacting piece 21 and ensure that the compacting piece 212 will not be easily blocked by garbage during operation.

[0076] When the dust box 100 is installed on the cleaning device, the cleaning device is provided with a vacuum pump and other structures connected to the suction channel 13 of the dust box 100, and a filter 131 is provided in the suction channel 13, such as a HEPA structure. When the vacuum pump is working, dust, hair and other garbage in the space can enter the accommodating chamber 101 from the dust suction port 102, and the dust, moisture, hair and other garbage carried in the garbage are filtered out by the filter 131, which will not affect the vacuum pump.

[0077] In some usage scenarios, the timing for starting garbage compaction can be: when the garbage enters the accommodating chamber 101, starting the driving assembly 22 can drive the compacting member 21 to translate or swing in the accommodating chamber 101, thereby compacting the garbage in the accommodating chamber 101, improving the space utilization rate of the accommodating chamber 101, and reducing the number of times the dust box 100 is dumped.

[0078] In some other usage scenarios, the garbage compaction may be started at the following time: after detecting that the amount of garbage in the accommodating cavity 101 reaches a certain amount, the driving component 22 is started to compact the garbage.

[0079] In some other usage scenarios, the garbage compaction can be started at the following time: detecting that there is garbage in the dust box 100, starting the drive assembly 22 to perform initial compaction on the garbage, then controlling the vacuum pump to perform vacuuming while performing garbage compaction, or detecting that the amount of garbage in the dust box 100 reaches a certain level before performing garbage compaction.

[0080] It can be understood that the timing at which the drive assembly 22 in this embodiment drives the compacting member 21 to compact garbage is not limited to the above description. As long as it is other deformation methods based on the conception of this application, it is within the protection scope of this application.

[0081] On the other hand, the present application also provides a cleaning device, which may be, for example, a sweeping robot, a vacuum cleaner, etc. The cleaning device includes the dust box 100 in the above embodiment, and therefore, the cleaning device includes all the technical effects of the dust box 100 in the above embodiment. Since the technical effects of the dust box 100 have been described in detail above, they will not be repeated here.

[0082] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0083] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0084] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
