Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cleaning household appliances, and particularly to a dust box, a cleaning robot, and a cleaning device. Background Art

[0002] With the vigorous development of technology and artificial intelligence, intelligent cleaning household appliances are widely loved and relied on by people. The Chinese patent with the publication number CN110604512B discloses that a cleaning robot is provided with a separate dust inlet and a dust outlet on the dust box, and the Chinese patent with the publication number CN110604513A discloses that a dust outlet is generally provided with a shielding member. Before connecting to the base station for dust removal, the shielding member needs to cooperate with a limiting structure to close the dust outlet. When connecting to the base station for dust removal, the base station needs to be provided with an opening structure matching the limiting structure to release the limit. At the same time, the dust inlet needs to be separately closed to ensure a high dust outlet efficiency. Its structure is relatively complex, and there is a risk of failure in the repeated use of the limiting structure and the opening structure.

[0003] In related technologies, it is also common in the market that the dust inlet and the dust outlet of a cleaning robot are the same outlet. In order to increase the dust box capacity and prevent dust leakage, the dust inlet of the dust box is generally set at a relatively high position from the bottom of the dust box. However, there is a shortage that when the base station collects dust, it is difficult to take out heavier garbage due to the relatively high dust box outlet, resulting in residual debris in the dust box and poor dust outlet effect.

[0054] As Figures 1 to 8 shown, the present invention provides a dust box 100, referring to Figures 1 to 3 shown, which is applied to the technical field of intelligent cleaning household appliances.

[0055] It is defined that the box body has a height direction, and referring to the rectangular coordinate system O-XYZ in the attached Figures 1 to 8 drawing, the height direction of the box body 10 is the up-and-down direction, which is also the Z-axis direction. The extending direction of the dust valve is the X-axis rotation direction. The Y-axis is perpendicular to the X-axis and the Z-axis respectively, forming the above-mentioned coordinate system O-XYZ. The following embodiments use this as the azimuth reference benchmark.

[0056] In an embodiment of the present invention, the dust box 100 includes a box body 10. The box body 10 has a dust collection cavity 10A. The box body 10 is also provided with a dust inlet 10B, a dust outlet 10C, and a ventilation port 10D that communicate with the dust collection cavity 10A. The dust outlet 10C is located at the lowest position in the height direction of the box body 10, and the position of the dust inlet 10B is higher than that of the dust outlet 10C. The dust box 100 further includes a dust valve. The dust valve includes an inlet dust valve 30 and an outlet dust valve 50 that are movably arranged on the box body 10. The inlet dust valve 30 rotates in the dust collection cavity 10A to open or close the dust inlet 10B, and the outlet dust valve 50 rotates outside the dust collection cavity 10A to open or close the dust outlet 10C. Among them, in the initial state, the inlet dust valve 30 and the outlet dust valve 50 close the dust inlet 10B and the dust outlet 10C respectively. When vacuuming, the outlet dust valve 50 closes the dust outlet 10C, and the inlet dust valve 30 opens the dust inlet 10B. The air flow sequentially passes through the dust inlet 10B, the dust collection cavity 10A, and the ventilation port 10D, causing a negative pressure to be formed inside the box body 10. Dust debris enters the dust collection cavity 10A from the dust inlet 10B along with the air flow. When discharging dust, the inlet dust valve 30 closes the dust inlet 10B, and the outlet dust valve 50 opens the dust outlet 10C. The air flow sequentially passes through the ventilation port 10D, the dust collection cavity 10A, and the dust outlet 10C, causing a negative pressure to be formed inside the box body 10. Dust debris is discharged from the dust collection cavity 10A through the dust outlet 10C along with the air flow.

[0057] The technical solution of the present invention aims to solve the technical problems of residual debris in the dust collection box 100 and poor dust discharge effect by adopting the mutual cooperation and switching between the dust valve and the box body 10. In this embodiment, the dust collection box 100 includes a box body 10 and a dust valve rotatably connected to the box body 10. The box body 10 has a dust collection chamber 10A, an inlet 10B, an outlet 10C, and a ventilation port 10D that communicate with the dust collection chamber 10A. The ventilation port 10D is located on a side wall of the dust collection chamber 10A different from the inlet 10B. The dust valve includes an inlet dust valve 30 and an outlet dust valve 50 movably disposed in the box body 10. The inlet dust valve 30 and the outlet dust valve 50 cooperate to block the communication between the dust collection chamber 10A and the outside. The inlet dust valve 30 rotates in the dust collection chamber 10A to open or close the inlet 10B, and the outlet dust valve 50 rotates outside the dust collection chamber 10A to open or close the outlet 10C. In the initial state, both the inlet dust valve 30 and the outlet dust valve 50 are closed; when vacuuming, the outlet dust valve 50 closes the outlet 10C, and the inlet dust valve 30 opens the inlet 10B, and the air flow sequentially passes through the inlet 10B and the dust collection chamber 10A, and the dust debris enters the dust collection chamber 10A with the air flow from the inlet 10B; when discharging dust, the inlet dust valve 30 closes the inlet 10B, and the outlet dust valve 50 opens the outlet 10C, and the air flow sequentially passes through the ventilation port 10D, the dust collection chamber 10A, and the outlet 10C, and the dust debris is discharged from the dust collection chamber 10A with the air flow from the outlet. The position of the inlet 10B is higher than that of the outlet 10C, and the ventilation port 10D is located on the opposite side of the inlet 10B, which can effectively ensure the dust collection capacity of the dust collection chamber 10A. The outlet 10C is located at the lowest position in the height direction of the box body 10, which improves the smoothness of dust discharge and the dust discharge efficiency, reduces dust debris residue, has a simple structure and a good dust discharge effect, and is suitable for widespread promotion and use.

[0058] It can be understood that the dust collection box 100 is applied to a dust suction device. Corresponding to the dust suction device, there are a dust suction state and a dust discharge state. Both the dust suction state and the dust discharge state are the working states of the dust collection box 100. And in the working state, one of the inlet 10B and the outlet 10C must be in an open state. For example, in the dust suction state, the dust suction device generates a suction force from the outside towards the inside of the dust collection chamber 10A. At this time, under the action of the internal and external pressure difference generated by the suction force, the outlet dust valve 50 cooperates with the box body 10 to close the outlet 10C, and the inlet dust valve 30 rotates to open the inlet 10B; in the dust discharge state, the dust suction device generates a dust discharge wind force from the dust collection chamber 10A towards the outside. At this time, under the action of the internal and external pressure difference generated by the suction force, the inlet dust valve 30 cooperates with the box body 10 to close the inlet 10B, and the outlet valve 50 rotates to open the outlet 10C. When the dust collection box 100 is not working, that is, in the initial state, both the inlet dust valve 30 and the outlet dust valve 50 are in a closed state.

[0059] It should be noted that in the initial state, the dust inlet valve 30 of the present invention can naturally overlap with the dust outlet valve 50 due to gravity to close the dust inlet 10B, and the dust outlet valve 50 naturally closes the dust outlet 10C under the action of gravity, which can prevent the leakage of dust in the dust collection chamber 10A; or, in the initial state, the dust inlet valve 30 and / or the dust outlet valve 50 need to rely on external force to achieve the closing of the corresponding dust inlet 10B and / or dust outlet.

[0060] It should be noted that when the dust box 100 is in the dust suction state, the dust inlet valve 30 can only rotate towards the inside of the dust collection chamber 10A to open or close the dust inlet 10B; the dust outlet valve 50 can only rotate towards the dust passage 10E to open or close the dust outlet 10C. Among them, when the dust outlet 10C is closed, the dust outlet valve 50 abuts against and is limited to the box body 10 to maintain the closing stability of the dust outlet 10C; when the dust inlet 10B is closed, the dust inlet valve 30 overlaps with the dust outlet valve 50 to maintain the closing stability of the dust inlet 10B.

[0061] It can be understood that in a feasible embodiment, one of the dust inlet 10B and the dust outlet 10C is arranged parallel to the vertical plane or parallel to the horizontal plane, or the dust inlet 10B and the dust outlet 10C can be arranged in the same plane, or the dust inlet 10B and the dust outlet 10C can also be arranged in planes with an included angle. When necessary, the dust inlet valve 30 and the dust outlet valve 50 can be provided with corresponding switch support structures to facilitate the opening or closing of the dust inlet valve 30 and the dust outlet valve 50. The ventilation port 10D is located on the side of the box body 10 opposite to the dust inlet 10B, which is convenient for the orderly flow of air.

[0062] It can be understood that the dust inlet valve 30 and / or the dust outlet valve 50 need to rely on external force to achieve the closing of the corresponding dust inlet 10B and / or dust outlet. Among them, the external force support can be realized by magnetic attraction, or by using a switch support structure. The switch support structure can be set as a torsion spring, and the torsion spring is arranged on the rotation of the dust outlet valve 50 and / or the dust inlet valve 30 to form a torque around the axis of rotation to resist the wind traction during dust suction or dust discharge.

[0063] Optionally, the cartridge 10 includes a bottom plate 121 and a plurality of side plates 122. The bottom plate 121 and the plurality of side plates 122 enclose to form a dust collection chamber 10A. At least one side plate 122 includes at least a first section 131 and a second section 132. The first section 131 is spaced from the bottom plate 121 and is disposed at an angle. The dust inlet 10B is formed in the first section 131, and the dust inlet valve 30 is rotatably connected to the first section 131. The two opposite sides of the second section 132 are respectively connected to the first section 131 and the bottom plate 121. The second section 132 is disposed at an angle with both the first section 131 and the bottom plate 121. The dust outlet 10C is formed in the second section 132, and the dust outlet valve 50 is rotatably connected to the second section 132. The dust inlet 10B is communicated with the dust outlet 10C. Wherein, in the initial state, the free end of the dust outlet valve 50 abuts against and is limited by the bottom plate 121 and the edge of the side plate 122 adjacent to the dust outlet 10C, and the free end of the dust inlet valve 30 overlaps and is limited by the end of the dust outlet valve 50 rotatably connected to the side plate 122.

[0064] Referring Figure 3 As shown, in this embodiment, in the initial state, the dust inlet valve 30 of the present invention can naturally overlap on the dust outlet valve 50 due to gravity to close the dust inlet 10B, and the dust outlet valve 50 naturally closes the dust outlet 10C under the action of gravity, which can prevent the dust in the dust collection chamber 10A from leaking. Wherein, one of the plurality of side plates 122 is partially recessed towards the inside of the dust collection chamber 10A to form a first section 131 and a second section 132 arranged in sections. The first section 131 is located on the side plate 122 and extends obliquely towards the bottom plate 121. The edges of the second section 132 are respectively connected to the first section 131, the bottom plate 121 and the other two side plates 122 arranged opposite to each other, and the first section 131 is connected to the bottom plate 121 through the second section 132. The dust inlet 10B and the dust outlet 10C are respectively formed in the first section 131 and the second section 132 arranged at an angle, and the dust inlet 10B and the dust outlet 10C are directly communicated, and the dust inlet 10B is higher than the dust outlet 10C. The dust inlet valve 30 and the dust outlet valve 50 are cleverly matched to open and close the dust inlet 10B and the dust outlet 10C, or both close the dust inlet 10B and the dust outlet 10C, improving the dust discharge smoothness and dust removal efficiency, and the dust discharge is clean with less residue, no dust accumulation will occur, maintaining the cleanliness of the dust box and facilitating cleaning and maintenance.

[0065] Optionally, the cartridge 10 further includes an enclosing plate 133. The enclosing plate 133 is respectively connected to the first section 131 and the second section 132, and encloses with the first section 131 and the second section 132 to form a dust passage 10E. Wherein, when the dust inlet valve 30 closes the dust inlet 10B, the dust inlet valve 30 is parallel to the first section 131, and when the dust outlet valve 50 closes the dust outlet 10C, the dust outlet valve 50 is parallel to the second section 132.

[0066] In this embodiment, the cross-section of the enclosing plate 133 is in the shape of a U-shaped groove. The side plate 122 is connected to the opening of the U-shaped groove of the enclosing plate 133, and one end abuts against and is limited by the bottom plate 121. The end of the enclosing plate 133 connected to the bottom plate 121 and the bottom plate enclose a dust passing opening 10F. The first section 131, the second section 132 and the enclosing plate 133 jointly enclose a dust passing channel 10E. At this time, the dust passing opening 10F communicates with the dust collecting cavity 10A through the dust passing channel 10E. The settings of the dust inlet valve 30 and the dust outlet valve 50 facilitate switching the communication port between the dust passing channel 10E and the dust collecting cavity 10A. In the dust suction state, the dust inlet valve 30 opens the dust inlet 10B, and the dust passing channel 10E communicates with the dust collecting cavity 10A through the dust inlet 10B. In the dust discharging state, the dust outlet valve 50 opens the dust outlet 10C, and the dust passing channel 10E communicates with the dust collecting cavity 10A through the dust outlet 10C. This facilitates the intelligent switching of the dust flow channel during the dust suction state and the dust discharging state, and improves the working efficiency of the dust box.

[0067] It should be noted that one of the side plates 122 among the multiple side plates 122 of the box body 10 is formed by the structural connection of the first section 131 and the second section 132. Then, the enclosing plate 133 is used to enclose the dust passing opening 10F and the dust passing channel 10E with the first section 131, the second section 132 and the bottom plate 121. The first section 131 and the second section 132 are integrally connected, and the connection parts are respectively provided with notches at the first section 131 and the second section 132 to form an installation opening 12B, and the dust inlet valve 30 and the dust outlet valve 50 are installed at the installation opening 12B.

[0068] In this embodiment, the second section 132 is perpendicular to the bottom plate 121, and the plane where the dust outlet 12C is located is parallel to the second section 132. The first section 131 inclines towards the side away from the bottom plate 121, and the dust inlet 10B is opened on the first section 131. The inclination angle is such that the dust inlet 10B and the dust passing opening 10F are located at the opposite ends of the dust passing channel 10E, facilitating the connection between the dust inlet 10B, the dust passing channel 10E and the dust passing opening 10F. Among them, the dust inlet valve 30 and the dust outlet valve 50 are closed in the initial state to cut off the connection between the dust passing channel 10E and the dust collecting cavity 10A. In the dust suction state, the dust inlet valve 30 is opened to connect the dust passing channel 10E and the dust collecting cavity 10A. In the dust discharging state, the dust outlet valve 50 is opened to connect the dust passing channel 10E and the dust collecting cavity 10A. The above design cleverly makes the dust inlet valve 30 abut against the rotating side of the dust outlet valve 50 during rotation to close the dust inlet 10B, and makes the dust outlet valve 50 abut against the bottom plate 121 during rotation to close the dust outlet 10C. The structure is simple and effective, without the need to use complex limiting structures or opening structures, reducing the manufacturing cost of the dust box 100. The settings of the dust passing channel 10E, the dust outlet valve 50 and the dust inlet valve 30 make the air flow direction accurate. The dust passing opening 10F and the dust passing channel 10E are conducive to the wind traction in the centralized dust suction or dust discharging state, improving the stability and reliability of dust suction and dust discharging.

[0069] The above settings enable the dust box 100 to use a single opening design for the installation opening 12B (the installation opening 12B is formed by connecting the dust inlet 10B and the dust outlet 10C), and the dust inlet valve 30 and the dust outlet valve 50 are arranged at the dust passing opening 10F and cooperate with each other by being opened separately to switch between different channels for dust suction and dust discharge. One end of the dust outlet 10C is located at the lowest position flush with the bottom plate 121, and the dust inlet 10B is arranged at a higher position, so that dust can be smoothly sucked into the dust box 100 and can also be smoothly discharged during dust discharge, without dust accumulation residue, improving the smoothness and orderliness of dust suction and dust discharge, and having a good use effect.

[0070] It should be noted that the box body 10 can include an upper box 11 and a lower box 12 from top to bottom. The lower box 12 includes a bottom plate 121 and side plates 122, and the bottom plate 121 is provided with a dust passing opening 10F. The upper box 11 and the lower box 12 are detachably connected. The upper box 11 is provided with an upper accommodating groove 11A and a ventilation opening 10D communicating with the upper accommodating groove 11A. The lower box 12 is provided with a lower accommodating groove 12A, and the lower accommodating groove 12A and the upper accommodating groove 11A communicate to form a dust collection cavity 10A. The dust inlet 10B and the dust outlet 10C are opened on the groove side wall of the lower accommodating groove 12A, and the ventilation opening 10D is opened on the side of the upper box 11 facing the dust outlet 10C. When the dust box 100 is assembled with the cleaning robot 200, the fan for dust suction is arranged facing the ventilation opening 10D and communicates with the dust collection cavity 10A through the ventilation opening 10D. When working and sucking air, the pressure in the dust collection cavity 10A decreases, and the dust inlet valve 30 opens to suck dust when the external pressure is greater than the pressure in the dust collection cavity 10A.

[0071] It can be understood that the upper box 11 and the lower box 12 are detachably connected. Among them, one end of the upper box 11 is provided with a fixing member 111, and the other end is provided with a fastening member 112. The lower box 12 is provided with a fixing portion 123 corresponding to the fixing member 111 of the upper box 11 and a buckle 124 corresponding to the fastening member 112. When the upper box 11 and the lower box 12 are assembled, the fixing portion 123 and the fixing member 111 are matched and connected, and then the fastening member 112 and the buckle 124 are correspondingly buckled, so that the upper box 11 and the lower box 12 enclose to form the dust collection cavity 10A.

[0072] It can be understood that the enclosing member 133 and the lower box 12 are of an integrally formed structure. The dust box 100 can be an injection molded part, so the enclosing member 133 and the lower box 12 are integrally injection molded. The product material is not uniquely limited here.

[0073] It can be understood that a sealing member is also provided between the upper box 11 and the lower box 12. The sealing member is detachably fixed to one of the upper box 11 or the lower box 12, and the airtightness of the dust collection cavity 10A is improved when the upper box 11 and the lower box 12 are assembled.

[0074] It can be understood that the dust box 100 further includes a mounting frame 125 which is disposed on the upper box 11 and adjacent to the ventilation opening 10D. Specifically, the mounting frame 125 is disposed on the other side of the ventilation opening 10D away from the dust collection chamber 10A. The mounting frame 125 is used to mount a filter cotton which is located between the dust suction fan 203 and the dust collection chamber 10A to prevent dust from passing through the ventilation opening 10D. The dust box 100 further includes a filter screen frame 126 with a filter screen which is disposed in the dust collection chamber 10A. The filter screen frame 126 is used to mount the filter screen to prevent larger particle dust from passing through the filter screen or the filter cotton, thereby prolonging the service life of the dust suction fan 203.

[0075] With reference to Figures 4 to 5 As shown, optionally, at least part of the bottom plate of the dust box is inclined and inclined from high to low towards the lowest part of the dust outlet.

[0076] It should be noted that the bottom plate 121 can be set as a flat plate parallel to the horizontal plane; it can also be set as a flat plate at an angle with the horizontal plane; it can also be set as two flat plates, one part of which is parallel to the horizontal plane and the other part is at an angle with the horizontal plane. In the following, part of the bottom plate 121 is parallel to the horizontal plane and the other part is at an angle with the horizontal plane.

[0077] In this embodiment, the bottom plate 121 includes a straight section 1211 and an inclined section 1212. The straight section 1211 is adjacent to the dust outlet 10C; the inclined section 1212 is disposed on the side of the straight section 1211 away from the dust outlet 10C. The inclined section 1212 is connected to the straight section 1211 and is inclined towards the dust passing opening 10F, so that the connection between the inclined section 1212 and the straight section 1211 forms an obtuse angle, and the size of the obtuse angle is greater than a right angle and less than a flat angle. The setting of the inclined section 1212 causes the dust entering the dust collection chamber 10A to accumulate towards the straight section 1211 and the dust outlet 10C under the action of the inclined section 1212, which is convenient for improving the dust discharge speed and efficiency when the dust outlet 10C is opened for dust discharge. Among them, the setting of the straight section 1211 causes the dust to accumulate in the dust collection chamber 10A, but does not cause too much pressure on the dust outlet valve 50, ensuring the stable closing of the dust outlet valve 50 and the stable progress of the dust suction process.

[0078] It can be understood that the area of the straight section 1211 is slightly smaller than the area of the inclined section 1212. The angle between the inclined section 1212 and the horizontal plane is the supplementary angle of the above obtuse angle, and the supplementary angle is set as α, and α satisfies: 10° ≤ α ≤ 45°. The common values that α can take are 10°, 15°, 20°, 25°, 30°, 35°, 40° and 45°. Within the above value range, most of the dust in the dust collection chamber 10A can be gathered near the dust outlet 10C, which is convenient for the cleanliness of dust discharge.

[0079] Optionally, the dust inlet valve 30 includes a dust inlet rotating shaft 32 and a dust inlet baffle 31. The dust inlet rotating shaft 32 is rotatably connected to the box body 10, and the dust inlet baffle 31 is connected to the dust inlet rotating shaft 32. In the initial state, the dust inlet baffle 31 abuts against and is limited by the side wall of the box body 10 adjacent to the dust inlet 10B under the action of gravity to close the dust inlet 10B.

[0080] Optionally, the dust outlet valve 50 includes a dust outlet rotating shaft 52 and a dust outlet baffle 51. The dust outlet rotating shaft 52 is rotatably connected to the box body 10. The dust outlet baffle 51 is connected to the dust outlet rotating shaft 52, and the dust outlet baffle 51 abuts against and is limited by the side wall of the box body 10 adjacent to the dust outlet 10B to close the dust outlet 10C.

[0081] In this embodiment, the edges of the box body 10 where the dust inlet 10B and the dust outlet 10C are opened are provided with a first mounting portion 13A and a second mounting portion 13B which are spaced apart. The dust inlet valve 30 is rotatably connected to the first mounting portion 13A, and the dust outlet valve 50 is rotatably connected to the second mounting portion 13B. In the dust suction state, the dust inlet valve 30 opens the dust inlet 10B, and the side of the dust outlet valve 50 away from the dust inlet valve 30 abuts against and is limited by the inner wall of the dust passing port 10F, that is, the side of the dust outlet valve 50 away from the dust inlet valve 30 abuts against and is limited at the opening of the dust passing port 10F opened on the bottom plate 121. In the dust discharging state, the dust outlet valve 50 opens the dust outlet 10C, and the side of the dust inlet valve 30 away from the first mounting portion 13A overlaps and limits the dust outlet valve 50.

[0082] Wherein, the first mounting portion 13A is adjacent to one end of the dust inlet 10B away from the dust outlet 10C. The dust inlet valve 30 includes a dust inlet baffle 31 and a dust inlet rotating shaft 32. The dust inlet rotating shaft 32 is rotatably connected to the first mounting portion 13A. The dust inlet baffle 31 swings in the dust collecting chamber 10A under the action of the first fixing member, and cooperates with the dust suction state or the dust discharging state to open or close the dust inlet 10B. One end of the dust inlet baffle 31 away from the dust inlet rotating shaft 32 is connected to the dust outlet rotating shaft 52 to close the dust inlet 10B. The second mounting portion 13B is provided at one end of the box body 10 adjacent to the dust outlet 10C and away from the bottom plate 121. The dust outlet valve 50 includes a dust outlet baffle 51 and a dust outlet rotating shaft 52. The dust outlet rotating shaft 52 is rotatably connected to the second mounting portion 13B. The dust outlet baffle 51 swings in the dust passing channel 10E under the action of the dust outlet rotating shaft 52, and cooperates with the dust suction state or the dust discharging state to close or open the dust outlet 10C. One end of the dust outlet baffle 51 away from the dust outlet rotating shaft 52 is connected to the bottom plate 121 to close the dust outlet 10C. The structure is simple and the cooperation is ingenious, enabling the dust suction and dust discharging to proceed in an orderly manner.

[0083] It can be understood that the first installation part 13A accommodates the two end parts of the dust intake rotating shaft 32 protruding from the dust intake baffle 31, and the second installation part 13B accommodates the two end parts of the dust outlet rotating shaft 52 protruding from the dust outlet baffle 51. The first installation part 13A and the second installation part 13B can be set as installation grooves. The dust intake rotating shaft 32 and the dust outlet rotating shaft 52 are respectively arranged in the installation grooves at corresponding positions and are rotationally connected with the inner wall of the installation groove. The dust intake baffle 31 and / or the dust outlet baffle 51 are in movable abutment with the inner wall of the dust passage 10E to increase the airtightness of the component cooperation and improve the continuity and smoothness of the dust suction state and the dust discharge state.

[0084] It can be understood that the dust box 100 further includes a limiting member 61, and the limiting member 61 is arranged on the side of the box body 10 adjacent to the dust outlet 10C; in order to improve the stability of the closing of the dust valve, the number of the limiting members 61 is set to two. When the dust outlet valve 50 rotates to abut against the bottom plate 121, the two sides perpendicular to the bottom plate 121 abut against the two limiting members 61 for limiting, accurately limiting the closing position of the dust outlet valve 50, so that it will not move into the dust collection cavity 10A away from the abutment with the bottom plate 121 due to the large dust suction force, and under the suction force of the dust suction, the dust outlet valve 50 will not move into the dust passage 10E away from the abutment with the bottom plate 121, ensuring the stability of the accommodation space of the dust collection cavity 10A in the dust suction state.

[0085] It can be understood that the dust box 100 is also provided with two limiting strips corresponding to the dust intake valve 30. The two limiting strips are arranged on the side plate 122 and are arranged in parallel. When the dust intake valve 30 rotates to abut against and limit the second rotating part 52 of the dust outlet valve 50, the two sides facing the dust passage 10E abut against the two limiting strips for limiting, accurately limiting the closing position of the dust outlet valve 50 and increasing the airtightness when the dust intake valve 30 closes at the same time.

[0086] It can be understood that the arrangement of the two limiting members 61 not only improves the closing stability of the dust outlet valve 50, but also increases the airtightness when the dust outlet valve 50 closes, so that the air flow passes through the dust passage opening 10F, the dust passage 10E and the dust intake port 10B and enters the dust collection cavity 10A in sequence.

[0087] Optionally, the dust box 100 further includes a first magnetic part 63 and a second magnetic part 64. The first magnetic part 63 is arranged in the box body 10 and is arranged on both sides adjacent to the dust outlet 10C; the second magnetic part 64 is arranged at one end of the dust outlet valve 50 adjacent to the bottom plate 121. The first magnetic part 63 and the second magnetic part 64 are magnetically attracted and connected to close the dust outlet 10C by the dust outlet valve 50; under the action of an external suction force, the first magnetic part 63 and the second magnetic part 64 are separated, and the dust outlet valve 50 opens the dust outlet 10C.

[0088] In this embodiment, the arrangement of the first magnetic attracting member 63 and the second magnetic attracting member 64 strengthens the abutment between the dust outlet valve 50 and the box body 10, ensures the closing stability of the dust outlet valve 50 in the dust suction state. The stable abutment between the dust outlet valve 50 and the bottom plate 121 effectively increases the effective capacity of the dust box 100, improves the sustainability of the dust suction state, reduces the dust discharge times, and enhances the user satisfaction.

[0089] Optionally, the dust outlet 10C is formed in the bottom of the box body 10, that is, the dust outlet 10C is formed in the bottom plate 121. The dust outlet 10C in this embodiment is the same as the dust passing opening 10F in the above embodiment. The dust outlet valve 50 is rotatably connected to the bottom of the box body 10 to open or close the dust outlet 10C; the dust inlet 10B is formed in the side of the box body 10, and the dust inlet valve 30 is rotatably connected to the side of the box body 10 to open or close the dust inlet 10B. The rotation axis of the dust inlet valve 30 is higher than the rotation axis of the dust outlet valve 50; wherein, in the initial state, the dust inlet valve 30 abuts against and is limited to the edge of the side of the box body 10 adjacent to the dust inlet 10B under the action of gravity, and the dust outlet valve 50 closes the dust outlet 10C under the suction force of the first magnetic attracting member 63 and the second magnetic attracting member 64.

[0090] The present invention further provides a cleaning robot 200, which is applied to intelligent cleaning household appliances. With reference to Figure 6 As shown, the cleaning robot 200 includes a housing and a dust box 100 as described in any one of the above. The specific structure of the dust box 100 refers to the above embodiment. Since the cleaning robot 200 of the present invention adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the housing has an installation cavity and an opening 200A communicating with the installation cavity; the dust box 100 is disposed in the installation cavity, and the opening 200A is communicated with the dust collection cavity 10A of the dust box 100 through the dust passing channel 10E of the dust box 100.

[0091] In this embodiment, the housing includes a mounting plate 201 and a cover body. The mounting plate 201 and the cover body are detachably connected and enclose to form a mounting cavity. A mounting position 202 is provided in the mounting cavity. The dust box 100 is detachably disposed in the mounting position 202, and the dust passing port 10F of the dust box 100 is correspondingly arranged opposite to the opening 200A. An avoidance port 200B is provided on the mounting position 202 corresponding to the ventilation port 10D of the dust box 100. The cleaning robot 200 further includes a suction fan 203. The suction fan 203 is disposed in the mounting cavity and is located at the avoidance port 200B. The suction fan 203 communicates with the dust box 100 through the avoidance port 200B and the ventilation port 10D. In the dust suction state, the suction fan 203 is turned on to generate suction force. The suction force causes the dust inlet valve 30 to open the dust inlet 10B to communicate with the dust collection cavity 10A, the dust passing channel 10E, and the opening 200A. External dust sequentially enters the dust collection cavity 10A through the opening 200A, the dust passing port 10F, the dust passing channel 10E, and the dust inlet 10B, and stays in the dust collection cavity 10A. In the dust discharge state, the suction fan 203 is closed. When the external dust discharge fan is turned on to generate dust discharge suction force, the dust discharge suction force causes the dust outlet valve 50 to open the dust outlet 10C to communicate with the dust collection cavity 10A, the dust outlet 10C, the dust passing channel 10E, and the opening 200A. The dust in the dust collection cavity 10A sequentially leaves the dust collection cavity 10A through the dust outlet 10C, the dust passing channel 10E, and the dust passing port 10F, and is discharged from the cleaning robot 200 through the opening 200A.

[0092] It can be understood that a channel for dust debris and air flow to pass through may also be provided on the mounting plate 201 corresponding to the opening 200A. The two ends of the channel for heat generation are respectively arranged corresponding to the dust outlet 10C and the opening 200A, reducing the dispersion of air flow, improving the concentration and accuracy of air flow, and contributing to dust suction and dust discharge.

[0093] The present invention also proposes a cleaning device. With reference to Figures 7 to 8As shown, the cleaning device includes a base station 300 and a cleaning robot 200 as described above. The specific structure of the cleaning robot 200 refers to the above-mentioned embodiments. Since the cleaning robot 200 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one. Among them, the base station 300 is provided with a dust return port 300A. The housing of the cleaning robot 200 is detachably matched with the base station 300, and the dust return port 300A communicates with the opening 200A of the cleaning robot 200. A dust exhaust fan is provided in the base station 300. In the dust exhaust state of the cleaning robot 200, the dust exhaust fan is turned on. Under the suction of the exhaust fan, the dust inlet valve 30 closes to close the dust inlet 10B, and the dust outlet valve 50 opens the dust outlet 10C to communicate the dust collection chamber 10A with the dust passage 10E. The dust sequentially passes through the dust passage 10E, the dust inlet 10F, the opening 200A, and the dust return port 300A and enters the base station 300. The position of the dust outlet 10C is lower than that of the dust inlet 10B, which can achieve rapid dust exhaust and improve the dust exhaust efficiency, so that there is no residue in the dust box 100 of the cleaning robot 200, improve the smoothness of dust suction and dust exhaust when the cleaning robot 200 is in use, and improve the user satisfaction.

[0094] It should be noted that Figure 7 and Figure 8 the base station 300 in [reference numerals] is only a schematic diagram of the connection part between the base station 300 and the cleaning robot 200. It only needs to satisfy that the opening 200A of the cleaning robot 200 can communicate with the dust return port 300A of the base station 300, and the structure and shape of the base station 300 are not limited.

[0095] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
