Detailed Description

Embodiments of the present application are further described below with reference to the accompanying drawings. The same or similar reference numbers in the drawings refer to the same or similar elements or elements having the same or similar functions throughout. In addition, the embodiments of the present application described below with reference to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the present application.

In the present application, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.

In the related art, the cleaning robot includes a dust box for storing garbage during the operation of the cleaning robot. After the cleaning robot returns to the base station, the fan of the base station is connected to the dust box in an opposite way through the pipeline, and the fan of the base station generates pressure and air flow to enable the garbage in the dust box to be sucked into the dust collecting bag of the base station, so that the garbage in the dust box is collected. However, the current dust collection scheme is not reasonably designed, and cannot meet the high-standard dust collection requirement.

In particular, in the first aspect, since the air flow inside the dust box flows from the dust collection port of the dust box to the base station, the dust in the dust box is carried away under the flow of the air, and the opposite end of the dust collection port is airtight, and the air flow is absent, a large area dead angle area, i.e., a cleaning dead angle, easily occurs at the opposite end of the dust collection port.

In the second aspect, the base station sucks the garbage in the dust box into the dust collecting bag through the dust outlet of the dust box under the vacuum action, and in the vacuum dust collecting process, the dust inlet of the dust box is not sealed, so that the vacuum degree in the dust box is reduced, and the dust collecting efficiency is lost.

In a third aspect, due to the second aspect, the unsealing of the dust inlet makes most of the pressure and energy provided by the base station fan lost, resulting in low energy efficiency of dust collection. In order to improve the dust collection effect, a high-power motor is generally adopted, so that the generated noise is larger.

In the fourth aspect, the base station sucks the garbage in the dust box into the dust collecting bag through the dust outlet of the dust box under the vacuum action, and in the vacuum dust collecting process, the main machine fan of the dust box is not sealed, so that the vacuum degree in the dust box is reduced, and the dust collecting efficiency is lost.

In a fifth aspect, for the reasons described in the second aspect, the unsealing at the main blower causes a great majority of the pressure and energy loss provided by the base station blower, resulting in a low energy efficiency of dust collection. In order to improve the dust collection effect, a high-power motor is generally adopted, so that the generated noise is larger.

Referring to fig. 1 and 2, in order to address the above-mentioned problems, an embodiment of the present application provides a robot system 100. The robot system 100 includes a base station 20 and a cleaning robot 10.

The base station 20 includes a base station fan (not shown) for generating an air flow.

The cleaning robot 10 may be a floor sweeping robot, a floor mopping robot, a floor sweeping and mopping robot, a floor wiping robot, a window cleaning robot, a hand-held cleaner, a hand-push cleaner, or the like. In the embodiment of the present application, the cleaning robot 10 is the cleaning robot 10 having an automatic dust collection function. Referring to fig. 3 to 5, the cleaning robot 10 may include a dust box 11 to store dust, such as dust, etc., during operation. When the cleaning robot 10 is finished or the dust box 11 is full of the garbage, the garbage can return to the base station 20 to collect dust, and the garbage in the dust box 11 is cleaned, namely the base station 20 collects the dust of the cleaning robot 10.

The dust box 11 includes a dust collection port 111. The number of the dust collection ports 111 may be one or more, and the embodiment of the present application takes the number of the dust collection ports 111 as one example. The dust collection port 111 may be interfaced with a base station fan via a conduit. The base station 20 may collect dust from the cleaning robot 10 by vacuum. Specifically, during dust collection, the air flow and pressure generated by the base station fan enable the garbage in the dust box 11 to be sucked into the dust collecting bag of the base station 20 through the dust collecting opening 111.

Regarding the problems of the first aspect described above, taking fig. 3 and 6 as an example, the dust collection port 111 is located at the lower left corner of the dust box 11, and when the base station 20 collects dust on the cleaning robot 10, the air flow generated by the dust collection fan flows from the upper dust inlet 113 to the lower left corner of the dust collection port 111 (as in curve (1) of fig. 6), while the air flow flows from the lower main machine fan and the filter assembly 117 to the lower left corner of the dust collection port 111 (as in curve (2) of fig. 6). Thus, a dead space (e.g., region (3) in fig. 6) is formed at the opposite end of the dust collection port 111.

Therefore, referring to fig. 3, in the embodiment of the present application, the dust box 11 is further provided with an air inlet 112, and the air inlet 112 and the dust collecting opening 111 are located on opposite sides of the dust box 11, for example, when the dust collecting opening 111 is located on the left side of the dust box 11, the air inlet 112 is disposed on the right side of the dust box 11; when the dust collection port 111 is located on the right side of the dust box 11, the air inlet 112 is disposed on the left side of the dust box 11, which will not be described. Wherein, the left side includes upper left corner, left side intermediate position, left lower corner, and the right side includes upper right corner, right side intermediate position, right lower corner, and when dust collection mouth 111 is located the arbitrary position in the left side of dust box 11, intake 112 sets up in the arbitrary position in the right side of dust box 11, can understand that both are relative setting, and need not both be in same horizontal line completely, makes it just right. Of course, when both the dust collection port 111 and the air inlet 112 are aligned, the dust collection effect is better.

The air inlet 112 is used to allow air flow into the dust box 11 to flow from the dust collection port 111 to the base station 20 when the base station fan is in operation. Because the air inlet 112 and the dust collecting opening 111 are positioned on opposite sides of the dust box 11, the air path in the dust box 11 is redesigned when the dust collection is performed, when the base station fan works, air flow enters the dust box 11 from the air inlet 112 and flows to the base station 20 from the dust collecting opening 111, and the air flow in the dust box 11 flows through, for example, from left to right, from right to left, from upper to lower, or from lower to upper, so that no dead cleaning angle is easy to occur. For example, when the airflow flows from the upper side to the left side, dead corners are easy to be cleaned on the right side; when the air flow flows from the bottom to the right, dead angles are easy to be cleaned on the left side. The robotic system 100 of the present embodiment has the following advantages: the dead angle is not easy to clean, the cleaning effect is better, and under the effect that air runs through and flows, the garbage in the dust box 11 is more easily taken away, so that the dust collection efficiency can be improved.

Referring to fig. 7 to 9, when the air inlet 112 is disposed at a specific position, the air inlet 112 may be located at the top (as shown in fig. 7), the middle (as shown in fig. 8), or the bottom (as shown in fig. 9) of the dust box 11 opposite to the dust collecting opening 111, so that the air flow in the dust box 11 is facilitated to flow therethrough, and dead corners are not easy to be cleaned.

In some embodiments, the air inlet 112 is located at the bottom of the dust box 11 on the side opposite the dust collection port 111.

Specifically, the bottom portion refers to a portion under the force of gravity, for example, in fig. 9, below 1/3 position in the height direction of the dust box 11 may be defined as the bottom portion. Since the dust collection port 111 is located at the left side of the dust box 11, the side of the dust box 11 opposite to the dust collection port 111 is the right side, i.e., the dust collection port 111 is located at the bottom of the right side of the dust box 11. It will be appreciated that dust and other waste will generally be deposited at the bottom of the dust box 11 under the action of gravity, so that the air inlet member 112 is disposed at the bottom to promote ventilation of the bottom, and the dust at the bottom is better sucked into the dust collecting bag of the base station 20, so as to further improve the dust collecting effect.

Referring to FIG. 3, in some embodiments, the dust box 11 further includes a dust inlet 113, and the air inlet 112 and the dust inlet 113 are located on different sides of the dust box 11.

Specifically, the dust inlet 113 is an opening through which the cleaning robot 10 sucks the dust from the surface to be cleaned into the dust box 11 when cleaning the surface to be cleaned (e.g., floor). The air inlet 112 and the dust inlet 113 are located on different sides of the dust box 11, that is, the dust inlet 113 is not located on the opposite side of the dust collecting opening 111, which is especially suitable for application situations where the air inlet 112 needs to be added. Since the opposite side of the dust collection port 111 is completely devoid of air circulation, it is more easy to clean dead corners.

The dust box 11 may have a cubic structure, such as a square structure, a rectangular parallelepiped structure, a cylindrical structure, or an irregular cubic structure. As shown in fig. 3 and 4, the dust box 11 may include a top surface 114, a bottom surface 115, and a side surface 116 connecting the top surface 114 and the bottom surface 115. The top surface 114 is opposite the bottom surface 115. Dust and other waste are generally collected at the bottom of the dust box 11 due to gravity, so that the dust collecting opening 111 can be arranged at the side 116 or the bottom 115 of the dust box 11, so that when air flows, the air flow penetrates through the bottom of the dust box 11 to take away the waste in the dust box 11, thereby having better cleaning effect. Illustratively, the dust collection port 111 is located on a side 116 of the dust box 11 to more conveniently interface with the base station fan via a conduit. Wherein, when the number of the side surfaces 116 is plural, the dust collection port 111 may be provided at any one of the side surfaces 116.

In an embodiment of the present application, the air intake 112 may be an air intake valve 1121 (as shown in fig. 3); or air intake 112 is a moveable door 1122 (shown in fig. 4 and 5).

Referring to FIG. 3, in one embodiment, the intake member 112 is an intake valve 1121. When dust collection is not performed, the base station fan does not work, the air inlet valve 1121 is in a closed state, and the dust box 11 can normally store garbage. In the dust collection, the base station fan generates an air flow flowing from the cleaning robot 10 to the base station 20, so that a negative pressure is formed in the dust box 11, and the air inlet valve 1121 is in an open state, so that the air flow can be allowed to enter the dust box 11 through the air inlet valve 1121, and the air flow penetrates through the air inlet valve 1121 to the opposite dust collection port 111, so that the garbage in the dust box 11 is sucked into the dust collection bag of the base station 20.

Referring to fig. 4 and 5, in one embodiment, air intake 112 is a moveable door 1122. When dust collection is not performed, the base station fan does not work, the movable door 1122 is in a closed state, and the dust box 11 can normally store garbage. When collecting dust, the base station fan generates air flow flowing to the base station 20 from the cleaning robot 10, so that negative pressure is formed in the dust box 11, and the movable door 1122 is in an open state, so that the air flow can be allowed to enter the dust box 11 from the movable door 1122, and the air flow penetrates through the movable door 1122 to the dust collecting opening 111 at the opposite side, so that the garbage in the dust box 11 is sucked into the dust collecting bag of the base station 20.

Further, when the base station fan works, taking the direction in fig. 4 as an example, the opening manner of the movable door 1122 may be: opening from left to right; or opening from the right side to the left side; or from the top to the bottom (i.e., from top surface 114 to bottom surface 115); or from the bottom side to the top side (i.e., from the bottom surface 115 to the top surface 114).

The movable door 1122 according to the embodiment of the present application is preferably opened from the bottom surface 115 toward the top surface 114, and in this case, the dust collection effect is excellent. Specifically, when the shutter 1122 is opened from the left side to the right side, a dead space is easily formed inside the right side of the shutter 1122 (i.e., near the surface inside the dust box 11), and the garbage is hidden in the right side behind the shutter 1122. When the shutter 1122 is opened from the right side to the left side, a dead space is easily formed inside the left side of the shutter 1122 (i.e., near the surface inside the dust box 11), and the garbage is hidden behind the shutter 1122. When the movable door 1122 is opened from the upper side to the lower side, a dead space is easily formed inside the lower side of the movable door 1122 (i.e., near the surface inside the dust box 11), and the garbage is hidden behind the lower side of the movable door 1122. When the movable door 1122 is opened from the bottom side to the top side, although a receiving area is formed inside the upper side of the movable door 1122 (i.e., near the surface inside the dust box 11), the garbage falls to the bottom inside the dust box 11 due to gravity, and is not easily left on the upper side of the dust box 11, so that the garbage is not easily hidden on the upper side behind the movable door 1122, the dust collection effect is good, and the garbage inside the dust box 11 can be cleaned more comprehensively.

When air inlet 112 is a removable door 1122, a reset element, such as a reset spring, may be provided on the dust box 11 that is coupled to the removable door 1122. When dust collection is performed, the movable door 1122 is opened under the action of negative pressure, and after dust collection is completed, the movable door 1122 can be restored to a closed state under the action of a return spring. The compression amount of the return spring when the movable door 1122 is in the open state is larger than the compression amount of the return spring when the movable door 1122 is in the closed state.

Referring to fig. 1, 2 and 10, the cleaning robot 10 further includes a roll brush cover 12. The roll brush cover 12 is located below the dust box 11. The roll brush cover 12 may be used to mount a cleaning unit, such as for example, a variety of components for a rag, a scraper bar, a roll brush, or a side brush. As shown in fig. 11, in one example, along the advancing direction of the cleaning robot 10, the lower edge of the roll brush cover 12 may be designed in an upturned arc shape (i.e., the right side of the roll brush cover 12 in fig. 11 is upturned), and a certain included angle (i.e., approach angle) is formed between the roll brush cover and the floor or other surface to be cleaned, so as to facilitate obstacle surmounting.

The roll brush cover 12 is formed with a cover opening 121 (as shown in fig. 11), and the dust box 11 further includes a dust inlet 113 (as shown in fig. 3), and the cover opening 121 communicates with the dust inlet 113. Wherein, the cover opening 121 and the dust inlet 113 may be directly connected, or may be connected through a pipe. When the cleaning robot 10 is operated, the garbage on the surface to be cleaned is sucked into the dust inlet 113 through the cover plate opening 121 and then into the dust box 11 through the dust inlet 113.

The base station 20 includes a base 22, and the cleaning robot 10 is parked on the base 22 after the cleaning robot 10 returns to the base station 20. The cover opening 121 is above the base 22 and faces the base 22.

Regarding the above-described problem of the second aspect, when the base station 20 performs dust collection on the cleaning robot 10, the base station fan operates and the air flow flows from the air inlet 112 to the opposite dust collection port 111. In this process, the dust inlet 113 of the dust box 11 is not sealed, air will enter the dust box 11 from the gap between the base 22 and the cover opening 121, and the cover opening 121 and the dust inlet 113 sequentially, so that the vacuum degree in the dust box 11 is reduced, the partial pressure and energy provided by the base station fan are lost, and the dust collecting efficiency is lost.

Therefore, referring to fig. 12 to 22, in the embodiment of the present application, the base station 20 further includes a sealing member 23 disposed on the base 22, and the sealing member 23 is used to seal the gap between the base 22 and the cover opening 121. Because the sealing structure is added at the openings 121 of the base 22 and the cover plate, that is, the air flow is prevented from entering the dust box 11 from the dust inlet 113, the pressure release of the dust inlet 113 during dust collection can be prevented, the energy loss of a base station fan is avoided, and the vacuum dust collection efficiency is improved. When the base station 20 collects dust on the cleaning robot 10, the air flow can enter from the position of the air inlet 112 more intensively and flow to the dust collecting opening 111 at the opposite side, so that the air duct in the dust box 11 is optimized throughout the whole dust box 11. In addition, since the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, namely, the generated noise is not large, and thus the problem of the third aspect is avoided.

The sealing member 23 and the base 22 may be assembled separately or integrally formed, which is not limited herein. In one example, the seal 23 may be a seal ring structure. When the cleaning robot 10 is parked on the base 22, the sealing member 23 seals the gap between the ring of base 22 and the cover plate opening 121. Further, the sealing member 23 may be a flexible profiling sealing ring, so as to better press fit with the cover plate opening 121, and improve the sealing effect.

Referring to fig. 16, 19, 21 and 22, the sealing member 23 includes a guide portion 231 and a sealing portion 232, the slope of the guide portion 231 gradually increases, and the sealing portion 232 serves to seal a gap between the base 22 and the cover opening 121 in a direction in which the cleaning robot 10 returns to the base station 20 to park, i.e., in a right-to-left direction in fig. 16, 19, 21 and 22, or in a left-to-right direction in fig. 12.

Specifically, the sealing portion 232 is connected with the guiding portion 231, and the sealing portion 232 and the guiding portion 231 can be formed all the time, so that the structure is stable, and the process is simple. Along the direction that the cleaning robot 10 returns to the base station 20 to stop, the gradient of the guide part 231 gradually rises, so that the height of the cleaning robot 10 is gradually changed, the machine is convenient to recharge and clamp at the joint of the guide part 231 and the sealing part 232, and sliding is not easy to occur. When the cleaning robot 10 is parked in place, the roll brush cover 12 is positioned above the sealing part 232, and the sealing part 232 seals the edge position of the cover opening 121, preventing air flow from entering through the cover opening 121.

The upper surface of the guide 231 may be an inclined plane to facilitate the travel of the cleaning robot 10. The upper surface of the sealing portion 232 may be a smooth curved surface and may be sloped down to carry the roll brush cover 12 and to fit the arcuate configuration of the bottom of the roll brush cover 12.

In some embodiments, the slope of guide 231 ranges from [6 °,45 ° ]. That is, the slope of the guide 231 may be any slope between 6 degrees and 45 degrees. For example, the slope of the guide 231 may be 6 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, or the like. For example, the slope of the guide 231 in fig. 13 to 16 is small, and the slope of the guide 231 in fig. 17 to 22 is large.

It will be appreciated that an excessive slope of the guide 231, for example, greater than 45 degrees, will make recharging of the cleaning robot 10 difficult, not easy to travel, easy to turn over, and not high in safety. The slope of the guiding portion 231 is too small, so that the length of the guiding portion 231 is lengthened, so that the distance that the cleaning robot 10 needs to travel is too long, and meanwhile, the overall length of the base 22 is too long, which is not beneficial to miniaturization and placement of the base station 20. Repeated experiments show that the slope range of the guide part 231 is between 6 degrees and 45 degrees, so that the recharging convenience of the cleaning robot 10 and the miniaturization problem of the base station 20 can be effectively balanced, and better use experience can be achieved.

Referring to fig. 23, in one particular form of seal 23, seal 23 includes a hollow cavity 233 and a support rib 234. The support rib 234 may be located in the middle of the hollow cavity 233.

At this time, the sealing member 23 integrally forms an elastomer, and the partially designed supporting ribs 234 of the hollow cavity 233 can increase the deformability of the sealing member 23, so that the sealing effect is more reliable when the sealing member 23 seals the gap between the base 22 and the cover opening 121. The gap between the base 22 and the cover opening 121 is tightly filled by the elastic deformation and elastic restoring force of the sealing member 23. In one example, the seal 23 has a hardness (Shore A) of 25 degrees to 85 degrees to provide a suitable deformation effect.

In the embodiment of the present application, the sealing member 23 may also be configured to include a guide portion 231 and a sealing portion 232, where the guide portion 231 may reduce resistance during recharging of the machine, and the hollow cavity 233 and the support rib 234 are disposed on the sealing portion 232. The sealing portion 232 may have a circumferential width of 5-30mm to preferably seal and cover the edge of the cover plate opening 121.

Referring to fig. 10, the roll brush cover 12 includes an opening sidewall 122 for forming a cover opening 121. Referring to fig. 16, in another embodiment of the seal 23, the seal 23 includes an opening bead 235, and the opening bead 235 is in a corresponding position and interference fit with the opening sidewall 122.

Specifically, the cover opening 121 may be a circular opening, a rectangular opening, a square opening, a diamond opening, or the like, which is not limited herein. The opening sidewall 122 encloses a cover opening 121. The sealing member 23 may be protruded toward the opening sidewall 122 to form a circle of opening ribs 235 to seal the position of the opening sidewall 122 and to be interference fit with the opening sidewall 122 when the cleaning robot 10 is parked on the base 22. In one example, the interference between the opening ribs 235 and the opening sidewall 122 is about 0.5mm to form a certain extrusion force therebetween, so as to have a better sealing effect.

Referring to fig. 10 and 16, the cover opening 121 and the sealing member 23 are both square structures. The open sidewall 122 includes a first sidewall 1221, a second sidewall 1222, a third sidewall 1223, and a fourth sidewall 1224 that are joined end to end. Correspondingly, the opening ribs 235 include a first rib 2351, a second rib 2352, a third rib 2353 and a fourth rib 2354, which are connected end to end. The first side wall 1221 and the first rib 2351, the second side wall 1222 and the second rib 2352, the third side wall 1223 and the third rib 2353, and the fourth side wall 1224 and the fourth rib 2354 are respectively bonded and sealed correspondingly, so as to prevent air from entering the dust box 11 from each side.

Referring to fig. 3 and 4, the cleaning robot 10 further includes a main machine fan. When the cleaning robot 10 is cleaning a surface to be cleaned, the main machine fan operates to generate an air flow from the dust inlet 113 toward the inside of the dust box 11 to suck the dust of the surface to be cleaned into the dust box 11.

Regarding the above-described fourth aspect, when the base station 20 performs dust collection on the cleaning robot 10, the base station fan operates and the air flow flows from the air inlet 112 to the opposite dust collection port 111. In this process, the main fan of the dust box 11 is not sealed, and there is air circulation between the main fan and the inside of the cleaning robot 10, so that air can enter the dust box 11 from the main fan (in the case that the dust box 11 is further provided with the filter assembly 117, air passes through the filter assembly 117 and then enters the dust box 11 from the main fan), so that the vacuum degree in the dust box 11 is reduced, the partial pressure and energy provided by the base station fan are lost, and the dust collecting efficiency is lost.

Therefore, in the embodiment of the application, when the base station fan works, the host fan synchronously works. When the base station fan works, the main machine fan synchronously works, so that the energy loss of the base station fan at the main machine fan can be counteracted, and the dust collection efficiency is improved. In addition, since the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, namely, the generated noise is not large, and thus the problem of the fifth aspect is avoided.

Specifically, as shown in curve (2) in fig. 6, when the base station fan works, because the main machine fan of the dust box 11 is not sealed, there will be airflow entering the dust box 11 from the main machine fan and the filter assembly 117 along the direction of curve (2), and if the main machine fan is synchronously turned on during dust collection, the main machine fan works to generate a pulling force along the opposite direction of curve (2), so that the airflow flows from the dust box 11 to the filter assembly 117 and the main machine fan, thereby canceling the pressure and energy loss of the base station fan and ensuring dust collection efficiency.

Further, since the base station fan needs to generate air flow and pressure to suck a large amount of garbage in the dust box 11 into the dust collecting bag of the base station 20 from the dust collecting opening 111 at one time, compared with the case that the main machine fan sucks garbage on the surface to be cleaned, the power required by the base station fan is larger, so the power of the base station fan can be set to be larger than that of the main machine fan.

At this time, in order to prevent the air inlet 112 from being opened due to the negative pressure of the air flow generated by the main blower when the cleaning robot 10 cleans the surface to be cleaned (at this time, the air inlet 112 is not required to be opened, because the garbage on the surface to be cleaned enters the dust box 11 through the dust inlet 113, if the air inlet 112 is opened, the working efficiency of the main blower will be affected), the air inlet 112 with the opening pressure meeting the predetermined condition may be selected, for example, the opening pressure of the air inlet 112 is between the pressure provided to the air inlet 112 when the base blower is in operation and the pressure provided to the air inlet 112 when the main blower is in operation.

Thus, when the main blower is operated, since the pressure provided to the air inlet 112 by the main blower is smaller than the opening pressure of the air inlet 112, the air inlet 112 is in a closed state, so as to ensure the working efficiency of the main blower, thereby ensuring the cleaning effect of the cleaning robot 10 on the surface to be cleaned. When the base station fan works, the pressure provided by the base station fan to the air inlet piece 112 is larger than the opening pressure of the air inlet piece 112, and the air inlet piece 112 is in an opening state, so that air flow can flow from the air inlet piece 112 to the dust collecting opening 111 on the opposite side, the air flow runs through and flows, dead corners are not easy to be cleaned, and the dust collecting effect is improved.

In view of the above problems, the embodiment of the present application also provides a cleaning robot 10.

The cleaning robot 10 according to the embodiment of the present application collects dust through the base station 20. The cleaning robot 10 includes a dust box 11, and the dust box 11 includes a dust collection port 111. The dust box 11 is also provided with an air inlet 112, the air inlet 112 being located on the opposite side of the dust box 11 from the dust collection opening 111. The air inlet 112 is used to allow air flow into the dust box 11 to flow from the dust collection port 111 to the base station 20 when the base station fan is in operation.

It should be noted that the explanation of the robot system 100, the cleaning robot 10, and the base station 20 in the foregoing embodiments is equally applicable to the embodiments of the present application, and will not be explained here.

In the embodiments, the dust collection scheme is reasonable in design, and can meet the high-standard dust collection requirement.

Application scenario one:

after the cleaning robot 10 returns to the base station 20, the base station 20 collects dust for the cleaning robot 10. The base station fan works, and air flows from the air inlet piece 112 to the dust collection port 111 on the opposite side, so that dead angles are not easy to clean due to the fact that the air flows through the dust collection port 111, and a high dust collection effect is achieved.

And (2) an application scene II:

after the cleaning robot 10 returns to the base station 20, the base station 20 collects dust for the cleaning robot 10. The base station fan is connected to the dust box 11 through a pipeline in an opposite way, and generates pressure and air flow so that the garbage in the dust box 11 is sucked into a dust collecting bag of the base station 20. Because the base 22 of the base station 20 is provided with the sealing element 23, in the dust collection process, the sealing element 23 seals the gap between the base 22 and the cover plate opening 121, so that air flow is prevented from entering the dust box 11 through the cover plate opening 121 and the dust inlet 113 in sequence, the energy loss of a base station fan is avoided, and the vacuum dust collection efficiency is improved. In addition, as the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, and the generated noise is not large.

And (3) an application scene III:

after the cleaning robot 10 returns to the base station 20, the base station 20 collects dust for the cleaning robot 10. The base station fan is connected to the dust box 11 through a pipeline in an opposite way, and generates pressure and air flow so that the garbage in the dust box 11 is sucked into a dust collecting bag of the base station 20. Because the base station fan works, the main machine fan synchronously works, and the energy loss of the base station fan at the main machine fan can be counteracted in the dust collection process, so that the vacuum dust collection efficiency is improved. In addition, as the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, and the generated noise is not large.

And application scene IV:

after the cleaning robot 10 returns to the base station 20, the base station 20 collects dust for the cleaning robot 10. The base station fan is connected to the dust box 11 through a pipeline in an opposite way, and generates pressure and air flow so that the garbage in the dust box 11 is sucked into a dust collecting bag of the base station 20. In one aspect. When the base station fan works, air flows from the air inlet piece 112 to the dust collection port 111 on the opposite side, and because the air flows through, dead angles are not easy to clean, and the dust collection effect is high. On the other hand, as the base 22 of the base station 20 is provided with the sealing element 23, in the dust collection process, the sealing element 23 seals the gap between the base 22 and the cover plate opening 121, so that air flow is prevented from entering the dust box 11 through the cover plate opening 121 and the dust inlet 113 in sequence, energy loss of a base station fan is avoided, and the vacuum dust collection efficiency is improved. In addition, as the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, and the generated noise is not large. On the other hand, because the base station fan works, the main machine fan synchronously works, and the energy loss of the base station fan at the main machine fan can be counteracted in the dust collection process, so that the vacuum dust collection efficiency is improved. In addition, as the vacuum dust collection efficiency is ensured, the base station fan does not need to be replaced by a high-power motor, and the generated noise is not large.

Application scenario five:

when the cleaning robot 10 cleans a surface to be cleaned, the main machine fan operates to generate an air flow from the dust inlet 113 toward the dust box 11 to suck the dust of the surface to be cleaned into the dust box 11. Since the pressure provided by the host fan to the air intake 112 is less than the opening pressure of the air intake 112, the air intake 112 will be in a closed state to ensure the operating efficiency of the host fan.

When the base station 20 collects dust on the cleaning robot 10, since the pressure provided by the base station fan to the air inlet 112 is greater than the opening pressure of the air inlet 112, the air inlet 112 will be in an open state, so that the air flow can flow from the air inlet 112 to the dust collecting opening 111 on the opposite side, and the air flow runs through the dust collecting opening 111, so that dead cleaning angles are not easy to occur, and the dust collecting effect is improved.
