The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the present specification.

Referring to fig. 1 to 5, the present application provides a cleaning machine including: a housing 10, a dust box 20, a water tank 30, a driving assembly 50, a fan 60, and a dust suction passage 100. The dust box 20, the water tank 30, the driving assembly 50, the fan 60, and the dust suction passage 100 are disposed in a housing 10, and the housing 10 may be understood as a surface housing of the cleaning machine and may also be understood as a support structure supporting the entire cleaning machine. The housing 10 has a mounting cavity in which the dirt tray 20 and water tank 30 are placed. The housing 10 may protect the dirt box 20 and the water tank 30, as well as the drive assembly 50 and the fan 60. In which the dust box 20 is used to collect dust, debris, etc., and the water tank 30 is used to store cleaning water, which is supplied during cleaning, and participates in the cleaning to improve the cleaning effect.

Specifically, the housing 10 is provided with a mounting cavity and a dust suction passage 100, the mounting cavity being located in a central region of the housing 10; the dust suction passage 100 is provided at a front end region of the housing 10, near the mounting cavity; two driving assemblies 50 are arranged, and the two driving assemblies 50 are respectively arranged at two sides of the central line 110 of the shell and are adjacent to the installation cavity; the two driving assemblies 50 are symmetrically distributed on two sides with the center line 110 of the housing as a symmetry line. The driving assembly 50 is provided with a driving electrode and a driving wheel, and the driving electrode outputs power to the driving wheel to rotate the driving wheel, thereby driving the cleaning machine to move.

The fan 60 is arranged on the shell 10 and close to the central line 110 of the shell; the center of the fan 60 can be located on the center line 110 of the housing, so that the suction force formed on the left and right sides of the housing 10 is equal, which is beneficial to improve the cleaning effect. It is also possible that the centre of the fan 60 is located on either side of the centre line 110 of the housing and adjacent the centre line 110 of the housing, and that an effective suction is created.

The dust box 20 is arranged in the mounting cavity and is close to a driving assembly 50; the water tank 30 is disposed in the mounting cavity adjacent to the other drive assembly 50, and the dirt box 20 is disposed adjacent to the water tank 30. The dust box 20 and the water tank 30 are juxtaposed in the installation cavity, and the dust box 20 and the water tank 30 can be close to each other or spaced apart from each other. The close abutment of the two parts makes full use of the space of the installation cavity. Spaced apart from each other by a certain distance, the dust box 20 and the water tank 30 can be prevented from interfering with each other. Referring to fig. 1, the x direction is the front end of the housing 10, and the y direction is the rear end of the housing 10.

In this embodiment, the cleaning machine may be a sweeping robot, a mopping machine, or a vacuum cleaner. The shape of the housing 10 is generally circular, so that edges and corners are reduced, external articles can be prevented from being scratched, and the external articles are prevented from being damaged. The housing 10 is generally made of plastic, and the plastic is obtained by injection molding and is easy to process.

In the solution of the present embodiment, the driving assembly 50 is used for driving the housing 10 to move, and in the moving process, the fan 60 generates a suction force to suck the dust moving through the path into the dust box 20, and the cleaning effect is improved by sprinkling water through the water tank 30. The dust suction channel 100, the installation cavity and the fan 60 are sequentially arranged along the advancing direction of the housing 10, and the centers of the three are close to the center line 110 of the housing, so that the fan 60 can face the dust suction channel 100, and further, dust can be sucked into the dust box 20 more easily. In addition, the layout of the dust box 20 is more reasonable in a mode that the center of the dust box is deviated from the center of the mounting cavity, so that the volume of the water tank 30 or the dust box 20 is increased, the design can enable the water tank 30 to store more water or enable the dust box 20 to contain more dust and sundries, and the requirement of cleaning work is met. In one embodiment, the dust suction passage 100, the installation cavity and the blower 60 are sequentially arranged along the traveling direction of the housing 10, and the centers of the three are located in the same straight line.

In the related art, the dust box 20 is placed at the center of the housing 10, which compresses the space of the water tank 30, resulting in a reduction in the volume of the water tank 30. Even if the corner space of other structures is fully utilized, the water tank 30 needs to be designed in a copying way, the structure of the processed water tank 30 is complex, the cost is high, and even if the water tank 30 is designed in the copying way, the space of the water tank 30 is difficult to be greatly lifted.

As further illustrated by the above embodiments, the dirt box 20 is adjacent one drive assembly 50 and the water tank 30 is adjacent the other drive assembly 50 in such a manner that both the water tank 30 and the dirt box 20 are eccentrically positioned. The dust box 20 is positioned eccentrically such that the center of the dust box 20 is offset from the center of the housing 10. Thereby increasing the space for placing the receiving groove of the water tank 30, and the water tank 30 designed in this way can store more water, and meet the water requirement of cleaning work. In addition, the profiling design of the water tank 30 can be reduced, the processing difficulty is reduced, and the cost is reduced.

And the profile modeling design, the structure is complicated, also very inconvenient when installing the basin, and the installation is loaded down with trivial details. The embodiment can simplify the installation process and improve the installation efficiency.

The center of the dust box 20 is offset from the center of the housing 10, which is the center of the shape, i.e., the centroid, of the housing 10. The housing 10 is arranged symmetrically in front, rear, left and right directions, and the centroid is also the center of gravity. Likewise, the center of the dirt box 20 is the centroid of the dirt box 20. By the eccentric arrangement of the dust box 20, the distance between the dust box 20 and the inner wall surface of the housing 10 can be increased, the space for placing the water tank 30 is increased, and the volume of the water tank 30 can be increased.

In the above embodiment, when the volume of the installation cavity is V0 and the volume of the dust box 20 is V1, the following requirements are satisfied: V1/V0 is more than or equal to 20% and less than or equal to 80%. In this range, the dust box 20 is ensured to have a sufficient volume to collect dust. If less than 20%, the volume of the dust box 20 is too small to have enough space to accommodate dust. If it exceeds 80%, the volume of the dust box 20 is too large, taking up a large space in the installation chamber, and the volume of the water tank 30 is compressed. Specifically, the ratio of the volume V1 of the dust box 20 to the volume V0 of the mounting chamber may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%.

In the above embodiment, when the volume of the installation cavity is V0 and the volume of the water tank 30 is V2, the following requirements are satisfied: V2/V0 is more than or equal to 20% and less than or equal to 80%. In this range, the water tank 30 is ensured to have a sufficient volume to store water. If less than 20%, the volume of the water tank 30 is too small to have enough space to store water. If it exceeds 80%, the volume of the water tank 30 is too large, taking up a large space in the installation chamber, and compressing the volume of the dust box 20. Specifically, the ratio of the volume V2 of the water tank 30 to the volume V0 of the installation cavity may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%.

In the above embodiment, when the volume of the dust box 20 is V1 and the volume of the water tank 30 is V2, the following conditions are satisfied: V2/V1 is more than or equal to 20 percent and less than or equal to 80 percent. Specifically, the ratio of the volume V1 of the dust box 20 to the volume V2 of the water tank 30 may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%. Generally, the dust box 20 has a volume greater than the water tank 30.

Referring to fig. 3, in the above embodiment, the horizontal distance between the two driving assemblies 50 is L, and the horizontal width of the dust box 20 is L1, then: L1/L is more than or equal to 20 percent and less than or equal to 80 percent. Specifically, the ratio of the horizontal width L1 of the dust box 20 to the horizontal distance L between the two drive assemblies 50 may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, or 80%.

In the above embodiment, the horizontal distance between the two driving assemblies 50 is L, and the horizontal width of the water tank 30 is L2, the following requirements are satisfied: L2/L is more than or equal to 20% and less than or equal to 80%. Specifically, the ratio of the horizontal width L2 of the water tank 30 to the horizontal distance L between the two driving assemblies 50 may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%.

Referring to fig. 6, in order to enable the dust to be effectively collected. The dust box 20 comprises a lower box 210, the lower box 210 comprises a bottom plate 211 and a windward plate 212, the fan 60 is arranged at the rear end region of the shell 10, the windward plate 212 is arranged at one side of the bottom plate 211 far away from the fan 60, the windward plate 212 and the bottom plate 211 are obliquely arranged, a dust collection port 213 is arranged on the surface of the windward plate 212, and at least part of the dust collection port 213 corresponds to the fan 60; the dust can be introduced into the dust box 20 through the dust collection port 213 by the air flow generated by the fan 60. In order to improve the dust collecting effect, the dust collecting opening 213 may face the dust suction passage 100, so that more dust can be introduced into the dust box 20.

The dust box 20 further includes a filter screen 240, and the filter screen 240 is disposed on a side of the bottom plate 211 adjacent to the fan 60. The filter screen 240 may be a whole filtering structure, or the dust box 20 may include a bracket 250, the bracket 250 is disposed on the bottom plate 211, and the filter screen 240 is disposed on the bracket 250, so that the firmness of the filter screen 240 may be improved by the bracket 250. The filter screen 240 can trap dust filtered by the filter screen 240 in the dust box 20 during the process that the air flow enters from the dust collection port 213 and is filtered by the filter screen 240.

Furthermore, in order to better complete the dust collecting function of the dust box 20, the center of the dust collecting opening 213 may correspond to the center of the fan 60, the wind force at the center of the fan 60 is the largest, the dust is the most entrained, and the dust collecting effect may be improved by the opposite arrangement of the dust collecting opening 213. That is, although the center of the dust box 20 is offset from the center of the fan 60, the dust collection port 213 is provided corresponding to the fan 60. That is, the center of the dust box 20 is offset from the center of the fan 60, but the dust collection port 213 is disposed to face.

Of course, the size of the opening of the dust collecting port 213 is also related to the dust collecting effect, and the larger the opening is, the better the dust collecting effect is. For this reason, the windward plate 212 and the bottom plate 211 are inclined, and the contact area between the windward plate 212 and the airflow generated by the fan 60 can be increased by the inclined arrangement, so that the size of the opening area of the dust collection port 213 can be increased, and more dust can be collected.

In addition, the inclination direction of the windward plate 212 is inclined from the bottom plate 211 toward a direction away from the fan 60, which also increases the volume of the dust box 20. And an avoidance space is formed below the windward plate 212, which can prevent a roll brush for cleaning dust.

In order to reduce the dust leakage, the lower case 210 further includes a blocking piece 214, and the blocking piece 214 is located on a side of the windward plate 212 facing the filter screen 240 and rotatably covered on the dust collection port 213. The flap 214 is located inside the dirt box 20. When the cleaning machine is working, the fan 60 works, the fan 60 drives the airflow to flow, and under the action of the wind force formed by the airflow, the blocking piece 214 originally covering the dust collecting opening 213 is blown open, and the dust can enter the dust box 20. When the cleaning machine stops operating, the fan 60 also stops operating. Thus, the baffle 214 lacks the blowing action of the air flow, and automatically falls down and buckles on the dust collecting opening 213 under the action of the self gravity of the baffle 214, so as to prevent the dust from overflowing through the dust collecting opening 213.

In addition, in this embodiment, the blocking piece 214 is provided with a rotating shaft, the rotating shaft is disposed at the upper edge of the dust collecting port 213, and the rotating shaft can rotate in two directions. In this way, the flap 214 can also be turned upside down. The self-gravity action of the baffle plate 214 can be fully exerted.

Further, in order to improve the shielding effect of the blocking piece 214 on the dust collection port 213, the lower case 210 further includes a sealing ring 215, the sealing ring 215 is disposed on the blocking piece 214 or the windward plate 212, the windward plate 212 is covered on the dust collection port 213, and the sealing ring 215 seals the dust collection port 213. The seal ring 215 has certain flexibility, for example, the seal ring 215 is an ethylene-vinyl acetate copolymer (EVA). The ethylene-vinyl acetate copolymer has good flexibility, shock resistance, skid resistance and strong pressure resistance.

By the arrangement of the sealing ring 215, when the blocking piece 214 is covered on the dust collecting opening 213, the sealing ring 215 can be better contacted with the blocking piece 214, and a gap between the blocking piece 214 and the outer edge of the dust collecting opening 213 is reduced, so that the leakage of dust is reduced.

Among these, the sealing ring 215 is provided at two positions.

First, the packing 215 is provided on the baffle plate 214, and the packing 215 is adhered to or embedded in the baffle plate 214. The packing 215 swings as the flap 214 swings upward and downward. This may reduce design changes to the windward plate 212.

Secondly, the sealing ring 215 is arranged on the windward plate 212, specifically, the sealing ring 215 is embedded in or adhered to the outer edge of the dust collection port 213 and protrudes from the surface of the windward plate 212, and when the blocking piece 214 covers the dust collection port 213, the sealing ring 215 and the blocking piece 214 are contacted. This configuration can reduce the weight of the blocking piece 214, and can easily blow up the blocking piece 214 during dust collection.

In the above embodiment, the cleaning process of the dust collected intensively needs to be performed. The lower box 210 further comprises two side plates 216, the two side plates 216 are respectively arranged on two opposite sides of the bottom plate 211, one end of each side plate 216 is connected with the windward plate 212, and the other end of each side plate 216 is connected with the filter screen 240; the dust box 20 further comprises an upper cover plate 220 and a handle 230, the upper cover plate 220 is covered on the lower box 210, a dust collecting chamber for storing dust is formed between the upper cover plate 220 and the lower box 210, the handle 230 is rotatably connected to the upper cover plate 220, and the upper surface of the upper cover plate 220 is provided with a storage groove 221, and the storage groove 221 is used for storing the handle 230. The upper surface of upper cover plate 220 still sets up dodges mouthful 222, dodges mouthful 222 intercommunication and accomodates groove 221, when dismantling dirt box 20, goes to stimulate handle 230 through dodging mouthful 222, makes handle 230 atress more easily, makes the handle follow and accomodate the inslot 221 extrication. Correspondingly, a groove 231 is further arranged at the position, corresponding to the avoiding opening 222, of the handle, and the operation space for prying the handle when the handle is pulled is increased through the matching effect of the groove 231 and the avoiding opening 222.

The dust box 20 is detachably mounted in the housing 10, and for convenience of detachment, the dust box 20 is stressed by pulling the handle 230, so that the dust box 20 can be quickly pulled out and separated from the housing 10. By the detachable mode, when dust needs to be cleaned, the dust box 20 can be detached from the cleaning machine, and then the dust can be intensively treated.

In addition, the water tank 30 is generally fixed within the housing 10 and generally does not need to be moved. This also ensures that the cleaning machine is more solid overall, avoiding excessive structural looseness.

When cleaning some larger sundries, the sundries can be intensively treated by disassembling the dust box 20, but for the sundries with smaller volume, the sundries can be intensively treated by automatically sucking by the base station 70. Specifically, a dust exhaust port 201 is formed in a side plate 216 of the lower box 210, a dust exhaust port 101 is formed in the surface of the housing 10, the cleaning machine further includes a dust exhaust pipeline 40, one end of the dust exhaust pipeline 40 is connected to the dust exhaust port 101, and the other end of the dust exhaust pipeline is connected to the dust exhaust port 201; after the cleaning machine finishes working, the cleaning machine automatically returns to the base station 70, the base station 70 generates suction force by butting against the dust suction port 101, and dust in the dust box 20 is sucked out through the dust exhaust port 201, the dust suction pipeline 40 and the dust suction port 101 in sequence under the action of the suction force. Thereby completing the centralized treatment of the small-volume sundries.

In order to reduce the random leakage of dust, the lower box 210 of the dust box 20 includes a shaft cover 217, the shaft cover 217 is disposed corresponding to the dust exhaust duct 40, and is rotatably covered on the dust exhaust port 201. When the dust is drawn out, an air flow is generated under the action of suction force, the air flow impacts the rotating shaft cover 217, the rotating shaft cover 217 rotates to be opened, so that the dust box 20 is communicated with the outside, and the dust can smoothly pass through the dust drawing pipeline 40. And, the pivot lid 217 is connected with the elastic component, and under the air current impact, the pivot lid 217 is opened, and the elastic component produces the deformation this moment, and the elastic component produces the restoring force, and when stopping the suction operation, suction disappears, no longer has the air current to impact the pivot lid 217, and the pivot lid 217 drives the pivot lid 217 closed dust exhaust port 201 under the effect of elastic restoring force, avoids the dust to leak.

Referring to fig. 7, in order to ensure that dust can be effectively sucked out, the dust exhaust duct 40 includes a first connection section 410 and a second connection section 420, and an angle θ is formed between the first connection section 410 and the second connection section 420, and the angle θ satisfies: theta is more than 90 degrees and less than or equal to 180 degrees.

The cleaning machine is only acted upon to extract dust when it returns to the base station 70. The management base 710 is provided in the base station 70, and when the cleaning machine moves to the management base 710, the management base 710 partially wraps the cleaning machine, that is, the management base 710 can only contact with the half of the cleaning machine. Therefore, the dust exhaust duct 40 extends from the side plate 216 of the dust box 20, and needs to extend to the management warehouse 710, so that the dust exhaust duct 40 has a certain bending angle.

When the airflow passes through the dust exhaust duct 40, the airflow contacts the inner wall surface of the dust exhaust duct 40. If the angle between the first and second connector segments 410, 420 is 90 deg., the airflow passing through the first connector segment 410 impinges directly on the second connector segment 420, resulting in a reduction in suction. In addition, the two are arranged at a right angle or less than 90 degrees, dust can be accumulated at the corner position, and the dust is not easy to clean.

To this end, the angle between the first and second connection sections 410, 420 is greater than 90 ° to avoid the air flow impinging on the corner locations, which reduces friction between the air flow and the tube wall. In addition, the angle between the first connection section 410 and the second connection section 420 may be equal to 180 °, so that the position of the dust suction port 101 is closest to the position of the dust box 20, and the first connection section 410 and the second connection section 420 form a straight line. Thus, the angle θ can be set at 90 ° < θ ≦ 180 °, specifically, the angle θ can be 95 °, 100 °, 105 °, 110 °, 115 °, 120 °, 125 °, 130 °, 135 °, 140 °, 145 °, 150 °, 155 °, 160 °, 165 °, 170 °, 175 °, 180 °.
