It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to fig. 1 to 9.

Referring to fig. 1 to 7, the dust collecting device of the present invention includes a dust box 100 and a first dust collecting passage 200. Illustratively, the dust box 100 serves to receive and store garbage. It should be noted that the waste of the present invention can be particulate matter, paper dust and/or dust. The kinds of garbage are various, and the present embodiment does not limit the specific kind of garbage collected by the dust box 100.

Exemplarily, the dust box 100 has an accommodating space 110 and a first opening 120, wherein the accommodating space 110 is used for storing garbage. The first opening 120 is communicated with the accommodating space 110, and one side of the first opening 120 close to the bottom of the accommodating space 110 is flush with the bottom of the accommodating space 110, so that the garbage in the accommodating space 110 can be discharged from the first opening 120. The first end of the first dust collecting channel 200 is provided with a dust inlet 210, the second end of the first dust collecting channel 200 is provided with a dust outlet 220, the dust inlet 210 is communicated with the first opening 120, and the garbage in the accommodating space 110 can enter the first dust collecting channel 200 from the dust inlet 210 and be discharged from the dust outlet 220.

Illustratively, the first opening 120 may be opened at a sidewall of the dust box 100. One side of the first opening 120 close to the bottom of the accommodating space 110 is flush with the bottom of the accommodating space 110, that is, one side of the first opening 120 close to the bottom of the accommodating space 110 is flush with the bottom wall of the accommodating space 110, so as to avoid a step formed between the bottom wall of the accommodating space 110 and the first opening 120, and facilitate the removal of the garbage in the accommodating space 110.

Referring to fig. 3 to 6, the dust box 100 is provided with a sealing part 130, the sealing part 130 is disposed around the first opening 120, and the sealing part 130 is in sealing engagement with the first end of the first dust collecting passage 200. Illustratively, the sealing portion 130 is provided with a sealing ring, such that the sealing portion 130 can be sealingly engaged with the first dust collection channel 200 by the sealing ring. Optionally, the sealing portion 130 is opened with a sealing groove, and the sealing groove surrounds the first opening 120 along the sealing portion 130. The sealing ring is disposed in the sealing groove, and at least a portion of the sealing ring protrudes from a surface of the sealing portion 130 near the first end of the first dust collecting channel 200.

Illustratively, the first dust collection channel 200 can be used to scoop up the trash within the dust collection bin 100. For example, a fan or an air pump may be used to make the air flow in the dust collecting device flow from the dust collecting box 100 to the first dust collecting channel 200, and then the air flow is used to take the garbage in the dust collecting box 100 out along the first dust collecting channel 200.

In the above embodiment, the first opening 120 is in sealing fit with the first dust collecting channel 200, which is not only beneficial to removing garbage in the dust collecting box 100, but also can prevent particles or dust in the dust collecting box 100 from leaking out from the connection between the first opening 120 and the first dust collecting channel 200.

In an alternative embodiment, the sealing part 130 is detachably coupled to the first dust collecting passage 200, and the dust box 100 is detachable in a first direction with respect to the first dust collecting passage 200. The sealing part 130 has a first sealing surface 131, the first end of the first dust collection channel 200 has a second sealing surface, and the sealing part 130 and the first dust collection channel 200 are sealingly engaged by the first sealing surface 131 and the second sealing surface. The first sealing surface 131 and the second sealing surface are disposed obliquely, and the first sealing surface 131 and the second sealing surface are inclined in a direction away from the accommodating space 110 along the first direction.

When the dust collection box 100 is used, a part of garbage can be attached to the inner side wall of the dust collection box 100, which not only affects the removal of the garbage in the dust collection box 100, but also easily causes the bacteria breeding in the dust collection box 100. In the above embodiment, the sealing part 130 is detachably coupled to the first dust collecting passage 200 to facilitate the removal of the dust box 100 for cleaning or maintenance.

The dust box 100 is detachable in a first direction with respect to the first dust collection passage 200, i.e., the dust box 100 is separated from the first dust collection passage 200 by moving the dust box 100 in the first direction during the process of detaching the dust box 100. Illustratively, the first direction may be upward relative to the first dust collection passage 200. Of course, the first direction may also be a horizontal direction or a downward movement with respect to the first dust collection passage 200. For this reason, the present embodiment does not limit the specific orientation of the first direction.

In the above embodiment, the first sealing surface 131 and the second sealing surface are inclined in the first direction to a direction away from the accommodating space 110. That is, in the process of detaching the dust box 100 in the first direction, the distance between the first sealing surface 131 and the second sealing surface is gradually increased, so that the first sealing surface 131 and the second sealing surface are prevented from rubbing against each other, and the purpose of protecting the sealing structure of the first sealing surface 131 and the second sealing surface is achieved. In addition, the first sealing surface 131 and the second sealing surface can be hermetically engaged by a force acting in the opposite direction of the first direction during the process of mounting the dust box 100, thereby reducing the difficulty of assembling the dust box 100 with the first dust collecting channel 200.

Referring to fig. 1, in an alternative embodiment, the dust collecting apparatus further includes a mounting seat 1200 to which the dust box 100 is mounted. Illustratively, the mounting block 1200 is provided with a groove or a rail that is slidably fitted with the dust box 100. Illustratively, the dust box 100 is movable along the mount 1200 in a first direction or a direction opposite to the first direction. In this embodiment, during the process of mounting the dust box 100, the sealing part 130 can be in sealing engagement with the first end of the first dust collecting channel 200 only by moving the dust box 100 along the groove or rail of the mounting seat 1200. Further, the dust collecting device further comprises a locking member, and the locking member is respectively connected with the dust collecting box 100 and the mounting seat 1200 to limit the movement of the dust collecting box 100 along the first direction through the locking member, so that the relative fixation of the dust collecting box 100 and the first dust collecting channel 200 is realized, and the relative fixation of the dust collecting box 100 and the first dust collecting channel 200 is realized. It should be noted that the variety of locking members is many, such as screws, snaps, latches, etc. For this reason, the present embodiment does not limit the specific kind of the locking member.

Illustratively, the mount 1200 may provide a mounting base for the dust collecting device to support the dust collecting device through the mount 1200. In an alternative embodiment, in the case where the dust collecting device is applied to a cleaning robot, the mount 1200 may be a housing of the cleaning robot.

Of course, the dust box 100 and the first dust collecting channel 200 may also be directly connected by a snap, a screw, a latch, etc. so that the first sealing surface 131 and the second sealing surface can be sealingly engaged.

In an alternative embodiment, one of the dust box 100 and the first dust collecting passage 200 is provided with a magnetic member, and the other is provided with a magnetic member. Illustratively, the sealing portion 130 is provided with a magnetically attractive element. The first end of the first dust collecting passage 200 is provided with a magnetic attraction member. In the process of assembling the dust box 100 with the first dust collecting passage 200, the magnetic member and the magnetic member may be attracted to each other to assist the dust box 100 in being positioned and mounted, and the sealing performance between the first sealing surface 131 and the second sealing surface may be improved by the attraction force generated between the magnetic member and the magnetic member. Specifically, the magnetic member is a member that can generate a magnetic field, such as a magnet. The magnetic part is a part capable of generating magnetic force with the magnet, and specifically can be an iron sheet or a magnet.

Referring to fig. 4 to 6, the dust box 100 further includes a first blocking plate 140, the first blocking plate 140 is located at a side of the sealing portion 130 away from the accommodating space 110, the first blocking plate 140 is rotatably engaged with the sealing portion 130, and the first blocking plate 140 is rotatable between a first position and a second position with respect to the sealing portion 130. When the first shutter 140 rotates to the first position with respect to the sealing portion 130, the first shutter 140 closes the first opening 120. In a case where the first shutter 140 is rotated to the second position with respect to the sealing part 130, the first opening 120 communicates with the dust inlet 210. Illustratively, the first flap 140 may be hinged with the sealing portion 130. Optionally, when the first blocking plate 140 rotates to the first position relative to the sealing portion 130, the first blocking plate 140 at least partially abuts against a side of the sealing portion 130 away from the accommodating space 110.

In the above embodiment, in the case that there is a pressure difference between the accommodating space 110 and the inner space of the first dust collecting passage 200, the first blocking plate 140 may rotate to the second position or the first position with respect to the sealing part 130 by the atmospheric pressure. Illustratively, when the pressure inside the receiving space 110 is greater than the internal pressure of the first dust collecting passage 200, the first blocking plate 140 receives a pressure that urges the first blocking plate 140 to rotate toward the second position. When the pressure inside the accommodating space 110 is less than the internal pressure of the first dust collecting passage 200, the first blocking plate 140 receives a pressure that urges the first blocking plate 140 to rotate toward the first position.

In the cleaning process of the dust collecting device, the air in the accommodating space 110 can be extracted by the fan, so that a low-pressure environment is formed in the accommodating space 110, the dust collecting device not only can be used for sucking the garbage into the accommodating space 110, but also can suck the first baffle 140 to the first position, and the garbage is prevented from being discharged from the first dust collecting channel 200. It should be noted that one of the purposes of the first dust collecting channel 200 according to the embodiment of the present application is to discharge the garbage in the accommodating space 110 by using the first dust collecting channel 200 after the garbage in the accommodating space 110 reaches a certain amount, so that the garbage in the dust collecting box 100 can be cleaned without repeatedly disassembling the dust collecting box 100, and the number of times of disassembling the dust collecting box 100 by a user is reduced.

In the above embodiment, the first blocking plate 140 can block the first opening 120 during the cleaning operation of the dust collecting device, so as to prevent the collected garbage from overflowing from the first opening 120. In addition, the first baffle 140 can be automatically opened in the process of cleaning the garbage in the dust collecting box 100, so that a control circuit for controlling the first baffle 140 to be opened or closed is not required to be arranged, and the structure of the dust collecting device is simplified.

Referring to fig. 6, the dust collecting box 100 further includes a first elastic member 150, the first elastic member 150 is connected to the first blocking plate 140 and the sealing portion 130, respectively, and the first elastic member 150 can urge the first blocking plate 140 to rotate to a first position relative to the sealing portion 130. For example, the first elastic member 150 may urge the first blocking plate 140 to be in sealing engagement with the sealing portion 130, so that the dust collecting device can ensure that the first blocking plate 140 blocks the first opening 120 after the dust in the dust collecting box 100 is cleaned, thereby preventing the dust in the dust collecting box 100 from overflowing from the first opening 120 during the cleaning process. Alternatively, the first elastic member 150 may be a spring or a leaf spring. Specifically, the first elastic member 150 is a torsion spring. There are many kinds of elastic members, and for this reason, the present embodiment does not limit a specific kind of the first elastic member 150.

Referring to fig. 4, 8 and 9, the first dust collecting passage 200 has an arc shape in which the height of the dust outlet 220 is greater than the height of the dust inlet 210 in the height direction of the dust collecting apparatus. Exemplarily, the height direction of the dust collecting device refers to: the dust collecting device is in the vertical direction when cleaning the horizontal plane.

In the above embodiment, the first dust collecting channel 200 can prevent the residual garbage in the first dust collecting channel 200 from falling to the ground during the cleaning process of the dust collecting device. Illustratively, providing the first dust collecting passage 200 in an arc shape can reduce the resistance of the garbage moving in the first dust collecting passage 200, thereby facilitating the discharge of the garbage from the first dust collecting passage 200. The height of the dust outlet 220 is greater than that of the dust inlet 210, so that the garbage can be prevented from sliding off the dust outlet 220 in the cleaning process of the dust collecting device, and further the dust collecting device can be prevented from repeatedly cleaning partial areas.

Referring to fig. 8, in an alternative embodiment, the direction of the dust inlet 210 of the first dust collecting channel 200 is parallel to the bottom of the dust box 100, so as to reduce the resistance of the garbage entering the first dust collecting channel 200. Further, the flow direction of the dust outlet 220 is horizontally arranged to facilitate the connection of the first dust collecting passage 200 with the base station 700. It should be noted that the flow guiding direction of the dust inlet 210 refers to the flow direction of the gas or the garbage passing through the dust inlet 210; the flow direction of the dust outlet 220 refers to the flow direction of the gas or the garbage passing through the dust outlet 220.

Referring to fig. 2, the dust collection device further includes a cleaning mechanism 1100. Illustratively, the cleaning mechanism 1100 includes a mop assembly 1110 and a third drive member 1120. The third drive member 1120 is connected to the mop assembly 1110 such that the third drive member 1120 can power the mop assembly 1110. Illustratively, the third drive 1120 is an electric motor.

Referring to fig. 2, the height of the cleaning mechanism 1100 is less than the height of the first dust collecting passage 200 in the height direction of the dust collecting device. Alternatively, in the case where the first dust collecting passage 200 is arc-shaped, the third driving member 1120 is disposed near the inner circumferential side of the first dust collecting passage 200. The inner ring side of the first dust collection passage 200 means: the first dust collection passage 200 has a smaller radius of curvature.

The first dust collecting passage 200 is formed in an arc shape, that is, the first dust collecting passage 200 is protruded from the inner circumferential side of the first dust collecting passage 200 to the outer circumferential side of the first dust collecting passage 200, so that a recess is formed at the inner circumferential side of the first dust collecting passage 200. Illustratively, the third driver 1120 is at least partially positioned in a recess of the first dust collecting channel 200 to improve the compactness of the dust collecting device structure.

In the above embodiment, the first dust collecting channel 200 is arc-shaped, which can increase the height of the dust outlet 220, thereby not only preventing the bottom of the accommodating space 110 from forming a step with the dust inlet 210, but also preventing the garbage in the accommodating space 110 from being left. Moreover, the increased height of the dust outlet 220 enables the dust outlet 220 to be farther away from the mop assembly 1110, which can effectively prevent the mop assembly 1110 from wetting the edge of the dust outlet 220, and is beneficial to keeping the dust outlet 220 clean.

Referring to fig. 2 to 6, the dust box 100 includes a box body 160, a cover body 170, and a filter cartridge 180.

The cover 170 is provided with a second opening 171, the filter element 180 is provided on the cover 170, and the second opening 171 is communicated with the accommodating space 110 through the filter element 180. For example, during the dust collecting device cleaning operation, air in the dust collecting box 100 may be discharged from the second opening 171, so that a negative pressure is formed in the accommodating space 110 to draw the garbage into the accommodating space 110. Further, the filter element 180 can filter the air exhausted from the accommodating space 110 during the cleaning operation of the dust collecting device, so as to prevent the garbage in the accommodating space 110 from flowing and being exhausted with the air.

Referring to fig. 4 and 5, the dust box 100 is further opened with a third opening 190, and the third opening 190 is communicated with the accommodating space 110. The dust collecting device further includes a first driving member 300, the first driving member 300 is communicated with the second opening 171, and the first driving member 300 can draw the external garbage from the third opening 190 into the accommodating space 110. Illustratively, the first driver 300 may be a fan. For example, the blower sucks air in the accommodating space 110 to form a negative pressure in the accommodating space 110, so that external garbage can be drawn into the accommodating space 110 from the third opening 190.

In an alternative embodiment, the dust collecting apparatus further includes a suction channel 800. Illustratively, the second opening 171 is connected to the first drive member 300 via the suction channel 800. Illustratively, the suction channel 800 defines an air inlet 810 and an air inlet 820. The air inlet 810 is communicated with the second opening 171, and the air suction opening 820 is communicated with the first driving member 300, so that the first driving member 300 can provide power for the discharge of the gas in the accommodating space 110.

Referring to fig. 2 to 4, the suction channel 800 is detachably coupled to the cover 170 to facilitate the assembly and disassembly of the dust box 100. Further, the cover 170 has a third sealing surface, and the suction channel 800 has a fourth sealing surface, the third sealing surface and the fourth sealing surface being inclined away from the accommodating space 110 in the first direction. In the process of disassembling the dust collecting box 100 along the first direction, the distance between the third sealing surface and the fourth sealing surface is gradually increased, so that mutual friction between the third sealing surface and the fourth sealing surface can be avoided, and the purpose of protecting the sealing structure of the third sealing surface and the fourth sealing surface is achieved. In addition, in the process of installing the dust collecting box 100, the acting force in the opposite direction of the first direction can be utilized to enable the third sealing surface and the fourth sealing surface to be in sealing fit, so that the assembly difficulty of the dust collecting box 100 and the air suction channel 800 is reduced.

In an alternative embodiment, the dust box 100 may be fixed to the mounting seat 1200 to which the dust box 100 is mounted by means of screws or snaps. In this embodiment, the second opening 171 can communicate with the air inlet 810 only by fixedly mounting the dust collecting box 100 on the mounting seat 1200, and the third sealing surface and the fourth sealing surface are sealed. Typically, at least one of the third and fourth sealing surfaces is provided with a sealing ring, such that the third and third sealing surfaces sealingly cooperate via the sealing ring. In an alternative embodiment, one of the mounting base 1200 and the dust box 100 is provided with a magnetic member, and the other is provided with a magnetic member, so that the mounting base 1200 and the dust box 100 can be fixed by the magnetic force generated by the magnetic member and the magnetic member.

For example, the magnetic member of the present invention may be a magnet, and the magnetic member may be made of a magnetic material. The magnetic material can be: iron. Of course, the magnetic member can also be a magnet.

Further, the dust collecting apparatus further includes an exhaust duct 900 and a fixing member 1000. Illustratively, the exhaust pipe 900 is connected to the first driving member 300, so that the first driving member 300 can draw out air in the accommodating space 110 and discharge the drawn air along the exhaust pipe 900. Alternatively, the first driving member 300 may be fixed by the fixing member 1000. There are many types of the fixing member 1000. Illustratively, the fixing member 1000 may be a support bracket, a fixing plate, a bolt, or the like. For this reason, the present embodiment does not limit the specific kind of the fixing member 1000.

Referring to fig. 5 and 6, the dust collecting device further includes a second barrier 400, the second barrier 400 is disposed in the accommodating space 110, the second barrier 400 is rotatably engaged with the dust box 100, and the second barrier 400 rotates between a third position and a fourth position with respect to the dust box 100. When the second shutter 400 is rotated to a third position with respect to the dust box 100, the second shutter 400 blocks the third opening 190. The third opening 190 communicates with the accommodating space 110 in a state where the second shutter 400 is rotated to a fourth position with respect to the dust box 100.

Illustratively, in a case where the dust collecting device is in a cleaning operation, the second shutter 400 is in a fourth position so that external garbage can enter the interior of the dust box 100 from the third opening 190. In addition, after the cleaning operation is completed, the second shutter 400 is rotated to the third position to prevent the garbage in the dust box 100 from leaking through the third opening 190.

Referring to fig. 5 and 6, the third opening 190 is opened at a sidewall of the dust box 100. The side wall of the dust box 100, on which the third opening 190 is formed, is inclined.

In this embodiment, the drum brush 500 and the drum brush case 600 may assist in collecting the ground garbage into the accommodating space 110. In an alternative embodiment, the roll brush housing 600 has a fifth sealing surface, the dust box 100 has a sixth sealing surface, and the roll brush housing 600 and the dust box 100 are sealingly engaged by the fifth sealing surface and the sixth sealing surface. For example, at least one of the fifth and sixth sealing surfaces is provided with a sealing ring, so that the fifth and sixth sealing surfaces can be sealed by the sealing ring.

Illustratively, during dust collection, the first driving member 300 is opened, and the first driving member 300 sucks air in the dust box 100 through the air suction channel 800, so that a negative pressure is formed in the dust box 100, i.e., the atmospheric pressure outside the dust box 100 is greater than the atmospheric pressure inside the dust box 100. Further, the second barrier 400 may rotate toward the fourth position against the gravity and/or the elastic force of the second elastic member under the external atmospheric pressure, so that the third opening 190 is opened. Since the air pressure inside the dust box 100 is lower than the air pressure outside the dust box 100, the dust box 100 sucks air into the dust box 100 through the third opening 190. Further, the fourth opening 610 is communicated with the third opening 190, so that the garbage swept by the roller brush 500 can be sucked into the dust box 100 along with the airflow to achieve garbage collection.

It should be noted that, during the dust collection process, since a negative pressure is formed in the dust collection box 100, that is, the pressure inside the dust collection box 100 is lower than the pressure inside the first dust collection passage 200, the air pressure inside the first dust collection passage 200 will cause the first blocking plate 140 to rotate to the first position, so that the first blocking plate 140 blocks the first opening 120. Therefore, the garbage in the dust box 100 is not discharged from the first opening 120 during the dust collection process.

Referring to fig. 6, the cover body 170 includes a middle cover 172 and an upper cover 173, the upper cover 173 is disposed to overlap the middle cover 172, and a ventilation chamber is formed between the upper cover 173 and the middle cover 172, the ventilation chamber communicating with the second opening 171. The filter element 180 is detachably coupled to the middle cap 172, and the vent chamber is communicated with the accommodating space 110 through the filter element 180. Illustratively, the filter element 180 may be a screen. Optionally, the filter screen may snap fit with the middle cap 172 via a snap fit to facilitate servicing of the filter cartridge 180.

Referring to fig. 6, the upper cover 173 is provided with a positioning portion 176. Illustratively, the positioning portion 176 protrudes from a side of the upper cover 173 close to the middle cover 172. Further, in a case that the upper cover 173 is covered on the middle cover 172, the positioning portion 176 may at least partially abut against the filter element 180, so that the filter element 180 can be clamped and positioned by the upper cover 173 and the middle cover 172. Of course, the filter element 180 can also be fixed by screws or bolts, and for this reason, the embodiment does not limit the specific way in which the filter element 180 is connected with the middle cap 172.

Referring to fig. 6 to 9, the cover 170 further includes a first latch 174 to be latched to the cassette body 160 by the first latch 174. Further, the upper cover 173 is rotatably connected to the middle cover 172, and illustratively, the upper cover 173 is provided with a second latch 175, and the second latch 175 is latched to the middle cover 172.

Referring to fig. 6, in an alternative embodiment, the middle cover 172 is coupled to the case body 160 by a first rotation shaft, so that the middle cover 172 rotates around the first rotation shaft relative to the case body 160. Further, the upper cover 173 is connected to the middle cover 172 by a second rotation shaft, and the upper cover 173 can rotate around the second rotation shaft relative to the middle cover 172. Further, the first rotating shaft and the second rotating shaft intersect. Illustratively, a first axis of rotation is disposed along a first side of the middle cap 172 and a second axis of rotation is disposed along a second side of the middle cap 172.

Based on the dust collecting device, the utility model also provides a cleaning robot. The cleaning robot comprises the dust collecting device in any embodiment of the utility model.

Further, based on the cleaning robot of the utility model, the utility model also provides a base station. The base station 700 may be used to clean the dust box 100 of the cleaning robot according to the present invention. Referring to fig. 7, the base station 700 includes a second dust collecting passage 710, a second driving member 720, and a dust box 730, a first end of the second dust collecting passage 710 may be detachably connected with a second end of the first dust collecting passage 200, and the second dust collecting passage 710 may communicate with the dust outlet 220. The second end of the second dust collecting channel 710 is communicated with the dust box 730, the second driving member 720 is connected with the dust box 730, and the second driving member 720 can draw the garbage in the accommodating space 110 into the dust box 730. Illustratively, the second drive 720 may be a fan.

The cleaning robot of the present embodiment can cooperate with the base station 700 to clean the garbage in the dust box 100 of the cleaning robot, thereby reducing the user's need to clean the dust box 100.

Illustratively, in the process of drawing up the garbage in the dust box 100, the second driving member 720 discharges the air in the dust box 730, so that a negative pressure is formed in the dust box 730. Since the second dust collecting passage 710 is connected to the dust box 730 and the first dust collecting passage 200, respectively, a negative pressure can be formed in the first dust collecting passage 200 by the second driving member 720, i.e., the pressure in the first dust collecting passage 200 is lower than the pressure in the dust box 100. Accordingly, the first blocking plate 140 is pressed to rotate the first blocking plate 140 to the second position, so that the first opening 120 can communicate with the dust inlet 210. In the case that the first opening 120 is communicated with the dust inlet 210, the gas and the garbage of the dust box 100 can be drawn into the dust box 730 by the second driving member 720.

After the first opening 120 is communicated with the dust inlet 210, the pressure inside the dust box 100 is gradually reduced as the air and the garbage in the dust box 100 enter the dust box 730 along the first dust collecting channel 200 and the second dust collecting channel 710. As the pressure within the dust box 100 decreases, the atmospheric pressure outside the dust box 100 may cause the second shutter 400 to rotate to the fourth position such that the third opening 190 is opened. Therefore, the gas outside the dust box 100 enters the dust box 100 through the third opening 190.

It should be noted that the dust and garbage in the dust box 100 will move with the airflow. The airflow direction at the third opening 190 is: flows from the outside of the dust box 100 to the inside of the dust box 100. Therefore, the dust and dirt in the dust box 100 does not fall out of the dust box 100 through the third opening 190.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
