[0044] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0045] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0046] With the development of science and technology, various cleaning equipment, such as cleaning robots or cleaning base stations, have been widely used in various industries and have also entered people's work and life, bringing great convenience to people's lives. Among them, the cleaning robot is a self-moving robot, which includes but is not limited to a sweeping and mopping robot. The cleaning robot has a garbage collection container to collect dust particles and other garbage on the surface to be cleaned when the cleaning robot performs sweeping and vacuuming tasks on the surface to be cleaned.

[0047] A cleaning base station refers to a cleaning device used in conjunction with a cleaning robot. The cleaning base station can provide care for the cleaning robot to reduce the frequency of maintenance required by the user. For example, the cleaning base station can be used to charge the cleaning robot, collect dust, and clean the mopping parts of the cleaning robot. Among them, the cleaning base station is usually provided with a negative pressure device, a dust collection bag, a dust collection channel, and a dust collection port. The dust collection port is connected to the dust collection channel, and the dust collection bag is connected to the dust collection channel and the negative pressure device. The dust collection port is used to dock with the garbage collection container of the cleaning robot so that the garbage in the garbage collection container can enter the dust collection bag inside the cleaning base station through the dust collection port and the dust collection channel under the action of the suction provided by the negative pressure device.

[0048] However, when the cleaning robot drives into the cleaning base station, the walking trajectory of the cleaning robot usually passes through the dust collecting port of the cleaning base station, and the walking wheels of the cleaning robot are easily stuck and trapped at the bottom of the dust collecting port, resulting in the cleaning robot being unable to smoothly enter and exit the cleaning base station, affecting the normal operation of the cleaning robot. When designing the structure of the cleaning robot or the cleaning base station, the prior art usually avoids the position of the dust collecting port at the bottom of the cleaning base station by making the walking wheel tire trajectory avoid the position of the dust collecting port at the bottom of the cleaning base station, which limits the placement of the dust collecting port.

[0049] To this end, an embodiment of the utility model proposes a cleaning system so that the position of the dust collection port will not be restricted by the track of the walking wheel tire, and can also reduce the risk of the cleaning robot being stuck in the dust collection port when entering the cleaning base station, thereby ensuring that the cleaning robot can smoothly enter and exit the cleaning base station.

[0050] Figure 1 is a bottom view of the cleaning robot in this embodiment, Figure 2 is a schematic diagram of the structure of the cleaning base station in this embodiment, Figure 3 Schematic diagram of the structure of the cleaning system in this embodiment.

[0051] See also Figures 1 to 3 The cleaning system of this embodiment includes a cleaning robot 1, a cleaning base station 2 and a travel assisting mechanism 3, wherein the cleaning robot 1 has a garbage collection container, a dust outlet 11 is provided at the bottom of the cleaning robot 1, and the dust outlet 11 is connected to the garbage collection container; the cleaning base station 2 includes a supporting seat 21 for supporting the cleaning robot 1, and a dust collecting port 22 is formed on the supporting seat 21, and the dust collecting port 22 is used to connect to the dust outlet 11 of the cleaning robot 1; the travel assisting mechanism 3 is provided on the cleaning robot 1 and / or the cleaning base station 2, and is used to support the cleaning robot 1 when the walking wheels 12 of the cleaning robot 1 pass through the dust collecting port 22, so that the walking wheels 12 of the cleaning robot 1 can pass over the dust collecting port 22.

[0052] In this embodiment, the garbage collection container of the cleaning robot 1 is used to collect dust particles and other garbage on the surface to be cleaned when the cleaning robot 1 performs sweeping and vacuuming tasks on the surface to be cleaned, or to transport the garbage in the garbage collection container to the dust bag of the cleaning base station 2 when the cleaning robot 1 is docked with the cleaning base station 2.

[0053] Exemplarily, the garbage collection container is a dust box or a dust bag, and the garbage collection container is connected to the dust outlet 11 of the cleaning robot 1, and the dust outlet 11 is arranged at the bottom of the cleaning robot 1. When the cleaning robot 1 performs a cleaning task, the dust outlet 11 can be used as an entrance for garbage to enter the cleaning robot 1 from the outside, and the garbage enters the garbage collection container from the dust outlet 11, thereby completing the collection of external garbage. When the cleaning robot 1 transports garbage to the cleaning base station 2, the dust outlet 11 serves as an outlet for garbage transportation, and the garbage in the garbage collection container is transported from the dust outlet 11 to the cleaning base station 2. Alternatively, the cleaning robot 1 includes a dust inlet and a dust outlet 11, and the dust inlet and the dust outlet 11 are both connected to the garbage collection container. When the cleaning robot 1 performs a cleaning task, external garbage enters the garbage collection container through the dust inlet, thereby completing the collection of external garbage. When the cleaning robot 1 transports garbage to the cleaning base station 2, the garbage in the garbage collection container is transported from the dust outlet 11 to the cleaning base station 2.

[0054] Exemplarily, the cleaning base station 2 of this embodiment includes a bearing seat 21, which is used to bear the cleaning robot 1 so that the cleaning robot 1 can drive into the cleaning base station 2. Exemplarily, the bearing seat 21 is set at a certain slope, so that the edge of the bearing seat 21 smoothly transitions with the ground, thereby improving the stability of the cleaning robot 1 entering and exiting the cleaning base station 2.

[0055] Exemplarily, an anti-skid belt is provided on the surface of the supporting base 21 to prevent the running wheels 12 of the cleaning robot 1 from slipping, thereby further improving the driving stability of the cleaning robot 1 on the supporting base 21 .

[0056] In this embodiment, a dust collection port 22 is formed on the supporting seat 21. After the cleaning robot 1 enters the cleaning base station 2, the dust collection port 22 can be connected to the dust outlet of the cleaning robot 1 to collect the garbage in the garbage collection container of the cleaning robot 1 into the cleaning base station 2.

[0057] Exemplarily, the cleaning base station 2 also includes a negative pressure device, a dust collection bag and a dust collection channel. The dust collection port 22 is connected to the dust collection channel, and the dust collection bag is connected to the dust collection channel and the negative pressure device. The negative pressure device can be a fan, a vacuum pump, etc. After the dust collection port 22 is connected to the dust outlet 11 of the cleaning robot 1, the negative pressure device draws negative pressure, so that the garbage in the garbage collection container can enter the dust collection bag inside the cleaning base station 2 through the dust collection port 22 and the dust collection channel under the action of negative pressure.

[0058] In this embodiment, when the cleaning robot 1 enters the cleaning base station 2, the driving trajectory of the running wheel 12 of the cleaning robot 1 will pass through the dust collection port 22 of the cleaning base station 2. In order to reduce the risk of the running wheel 12 of the cleaning robot 1 being stuck by the dust collection port 22, the cleaning system of this embodiment also includes a travel auxiliary mechanism 3, which is used to support the cleaning robot 1 when the running wheel 12 of the cleaning robot 1 passes through the dust collection port 22, so that the running wheel 12 of the cleaning robot 1 can pass over the dust collection port 22. Specifically, the travel auxiliary mechanism 3 can be set on the cleaning robot 1, or on the cleaning base station 2, or on both the cleaning robot 1 and the cleaning base station 2.

[0059] Exemplarily, the travel auxiliary mechanism 3 can be a protrusion, a baffle, or a rubber pad. For example, a protrusion is provided at the bottom of the cleaning robot 1, and when the walking wheel 12 passes through the dust collection port 22, the protrusion abuts against the cleaning base station 2 to support the walking wheel 12, and prevents the walking wheel from getting stuck in the dust collection port 22, so that the walking wheel 12 can pass over the dust collection port 22. Alternatively, a protrusion is provided on the bearing seat 21 of the cleaning base station 2, and when the walking wheel 12 passes through the dust collection port 22, the protrusion abuts against the bottom plate of the cleaning robot 1 to support the walking wheel 12, and prevents the walking wheel from getting stuck in the dust collection port 22, so that the walking wheel 12 can pass over the dust collection port 22.

[0060] Alternatively, a baffle 32 is provided at the dust collection port 22, and when the running wheel 12 passes through the dust collection port 22, the baffle 32 supports the running wheel 12, so that the running wheel 12 can pass through the dust collection port 22. Alternatively, a rubber pad is provided at the edge of the dust collection port 22, and when the running wheel 12 passes through the dust collection port 22, the rubber pad can support the running wheel 12 and increase the friction of the running wheel 12, so that the running wheel 12 can pass through the dust collection port 22.

[0061] The travel assist mechanism 3 of this embodiment can support the cleaning robot 1 when the cleaning robot 1 passes through the dust collection port 22 of the cleaning base station 2, so that the walking wheels 12 of the cleaning robot 1 can pass over the dust collection port 22, so that the cleaning robot 1 can smoothly enter and exit the cleaning base station 2, thereby ensuring the normal operation of the cleaning robot 1.

[0062] In this embodiment, the traveling wheels 12 of the cleaning robot 1 may be driving wheels or universal wheels.

[0063] In one embodiment, the traveling wheel 12 includes two driving wheels and a universal wheel. The two driving wheels are arranged opposite to each other. The universal wheel is arranged on the normal line of the connecting line of the two driving wheels. The dust outlet 11 is arranged between the driving wheels and the universal wheel.

[0064] In some embodiments, see Figure 4 , Figure 4 Schematic diagram of the structure of the cleaning system in this embodiment. In this embodiment, the diameter of the running wheel 12 is greater than the width of the dust collecting port 22. When the running wheel 12 passes through the dust collecting port 22, since the diameter of the running wheel 12 is greater than the width of the dust collecting port 22, the running wheel 12 will not sink into the dust collecting port 22 or partially sink into the dust collecting port 22. In the case where the running wheel 12 does not sink into the dust collecting port 22, the running wheel 12 can easily cross the dust collecting port 22. In the case where the running wheel 12 is partially sunk into the dust collecting port 22, the running wheel 12 can overcome the resistance at the dust collecting port 22, thereby crossing the dust collecting port 22. At the same time, since the running wheel can cross the dust collecting port, the position of the dust collecting port 22 no longer needs to avoid the driving track of the running wheel 12, so that the placement position of the dust collecting port 22 on the cleaning base station 2 is no longer restricted.

[0065] like Figure 5 As shown, Figure 5 Schematic cross-sectional view of a cleaning system in one embodiment of the present application.

[0066] In this embodiment, on the cross-section of the dust collecting port 22 along the direction in which the cleaning robot 1 enters the cleaning base station 2, the dust collecting port 22 is arc-shaped. After the dust collecting port 22 is connected with the dust outlet 11 of the cleaning robot 1, the dust collecting port 22 sucks garbage toward the dust outlet 11. Since the dust collecting port 22 is arranged in an arc shape, the dust collecting port 22 can guide the garbage along the arc-shaped inner wall of the dust collecting port 22 into the dust collecting bag of the cleaning base station 2, thereby avoiding the accumulation of garbage at the dust collecting port 22, so that the garbage is collected more thoroughly.

[0067] In another embodiment, the walking wheel 12 includes a universal wheel, and the universal wheel is located in front of the dust outlet 11 along the direction in which the cleaning robot 1 enters the cleaning base station 2. In this way, after the universal wheel passes the dust collection port 22, the dust outlet 11 of the cleaning robot 1 can be docked and connected with the dust collection port 22 of the cleaning base station 2, thereby realizing dust collection of the cleaning base station 2.

[0068] In some embodiments, the travel auxiliary mechanism 3 includes an auxiliary protrusion 31. The auxiliary protrusion 31 of this embodiment is arranged on the cleaning robot 1 or the cleaning base station 2, and is used to support the cleaning robot 1 when the running wheels 12 of the cleaning robot 1 pass through the dust collection port 22, so that the running wheels 12 of the cleaning robot 1 can pass over the dust collection port 22. Exemplarily, the auxiliary protrusion 31 can be a part of the shell of the cleaning robot 1 or the cleaning base station 2, or it can be a support structure detachably arranged on the cleaning robot 1 or the cleaning base station 2, such as a support roller.

[0069] See also Figure 3 , Figure 3 This is a schematic diagram of the structure of a cleaning system in one embodiment of the present application.

[0070] In one embodiment, Figure 3 As shown, the auxiliary protrusion 31 is arranged at the bottom of the cleaning robot 1, and along the direction in which the cleaning robot 1 enters the cleaning base station 2, the auxiliary protrusion 31 is arranged outside the dust outlet 11 and is located in front of the dust outlet 11. When the running wheel 12 passes through the dust collecting port 22, the auxiliary protrusion 31 located in front of the dust outlet 11 supports the cleaning robot 1, so that the running wheel 12 of the cleaning robot 1 can pass over the dust collecting port 22. After the running wheel 12 passes over the dust collecting port 22, the dust outlet 11 of the cleaning robot 1 can dock and communicate with the dust collecting port 22 of the cleaning base station 2, thereby realizing dust collection of the cleaning base station 2. Specifically, when the running wheel 12 of the cleaning robot 1 passes through the dust collecting port 22 and at least partially sinks into the dust collecting port 22, the front end of the cleaning robot 1 in the moving direction is tilted downward. At this time, the auxiliary protrusion 31 located in front of the dust outlet 11 abuts against the bearing seat 21 of the cleaning base station 2, thereby supporting the cleaning robot 1, so that the running wheel 12 of the cleaning robot 1 can pass over the dust collecting port 22.

[0071] In another embodiment, Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the structure of a cleaning system in another embodiment of the present application. Figure 7 This is a schematic diagram of the scene after the traveling wheel passes over the dust collection port in the cleaning system of this embodiment.

[0072] In this embodiment, see Figure 6 The auxiliary protrusion 31 is provided on the supporting base 21 of the cleaning base station 2, and along the direction in which the cleaning robot 1 enters the cleaning base station 2, the auxiliary protrusion 31 is provided outside the dust collection port 22 and is located in front of the dust collection port 22. When the running wheel 12 passes through the dust collection port 22, the auxiliary protrusion 31 located in front of the dust collection port 22 supports the cleaning robot 1, so that the running wheel 12 of the cleaning robot 1 can pass over the dust collection port 22. Figure 7 After the walking wheel 12 passes over the dust collecting port 22 , the dust outlet 11 of the cleaning robot 1 can be docked and connected with the dust collecting port 22 of the cleaning base station 2 , thereby realizing dust collection of the cleaning base station 2 .

[0073] Specifically, when the running wheels 12 of the cleaning robot 1 pass through the dust collecting port 22 and are at least partially immersed in the dust collecting port 22, the front end of the cleaning robot 1 in the moving direction is tilted downward. At this time, the auxiliary protrusion 31 located in front of the dust collecting port 22 abuts against the bottom plate of the cleaning robot 1, thereby supporting the cleaning robot 1 so that the running wheels 12 of the cleaning robot 1 can pass over the dust collecting port 22.

[0074] In some embodiments, the auxiliary protrusion 31 is a roller, the roller is a fixed roller, the rotation axis of the fixed roller is substantially perpendicular to the direction in which the cleaning robot 1 enters the cleaning base station 2, or the roller is a universal roller.

[0075] In this embodiment, the auxiliary protrusion 31 is a roller, which may be a fixed roller, and the rotation axis of the fixed roller is substantially perpendicular to the direction in which the cleaning robot 1 enters the cleaning base station 2. It should be noted that substantially perpendicular can be understood as the angle between the rotation axis of the fixed roller in this embodiment and the direction in which the cleaning robot 1 enters the cleaning base station 2 is 90°±5°. In this embodiment, the roller may also be a universal roller.

[0076] In some embodiments, see Figure 8 , Figure 8 is a schematic diagram of the structure of the cleaning system in this embodiment, Fig. 9 This is a schematic diagram of a scene in which dust is collected after the traveling wheels in the cleaning system of this embodiment pass over the dust collecting port.

[0077] The travel assisting mechanism 3 of this embodiment includes a baffle 32 , which is movably disposed at the dust collecting port 22 and is used to support the traveling wheels 12 of the cleaning robot 1 when the traveling wheels 12 pass through the dust collecting port 22 .

[0078] The baffle 32 of this embodiment is used to support the running wheel 12 of the cleaning robot 1 when the running wheel 12 passes through the dust collection port 22, so that the running wheel 12 of the cleaning robot 1 can pass over the dust collection port 22. Specifically, the baffle 32 is movably arranged at the dust collection port 22. For example, when the cleaning robot 1 does not pass through the dust collection port 22, the baffle 32 is in a state of blocking the dust collection port 22, and the baffle 32 is rotatably connected to the dust collection port 22. When the running wheel 12 passes through the dust collection port 22, the baffle 32 supports the running wheel 12, so that the running wheel 12 can pass over the dust collection port 22; after the running wheel 12 passes through the dust collection port 22, and when the cleaning base station 2 collects dust, the baffle 32 rotates toward the inside of the dust collection port 22 to open the dust collection port 22, so that the dust collection port 22 is connected to the dust outlet 11 of the cleaning robot 1. Alternatively, the baffle 32 is telescopically connected to the dust collection port 22. When the cleaning robot 1 does not pass through the dust collection port 22, the baffle 32 extends to block the dust collection port 22, so that the baffle 32 is in a state of blocking the dust collection port 22. When the running wheel 12 passes through the dust collection port 22, the baffle 32 supports the running wheel 12 so that the running wheel 12 can pass over the dust collection port 22. After the running wheel 12 passes through the dust collection port 22, and when the cleaning base station 2 collects dust, the baffle 32 retracts into the dust collection port 22 to open the dust collection port 22, so that the dust collection port 22 is connected to the dust outlet 11 of the cleaning robot 1.

[0079] For example, in some embodiments, the cleaning base station 2 further includes a negative pressure device, which is connected to the dust collection port 22, and the baffle 32 is rotatably connected to the dust collection port 22. When the walking wheel 12 of the cleaning robot 1 passes through the dust collection port 22, the baffle 32 is in a state of blocking the dust collection port 22, and is used to support the walking wheel 12 (see Figure 8 After the running wheel 12 passes over the dust collecting opening 22, the baffle 32 is used to rotate under the suction of the negative pressure device to open the dust collecting opening 22 for dust collection (see Fig. 9 ).

[0080] In this embodiment, the negative pressure device can be a fan, a vacuum pump, etc. The negative pressure device is connected to the dust collection port 22. When the cleaning base station 2 performs the dust collection task, the negative pressure device is started and generates suction at the dust collection port 22 toward the inside of the dust collection port 22. The baffle 32 is rotatably connected to the dust collection port 22. For example, an elastic reset member 33 is provided at the rotation connection of the baffle 32. The elastic reset member 33 can be a torsion spring. One end of the elastic reset member 33 is connected to the baffle 32, and the other end of the elastic reset member 33 is connected to the bearing seat 21 of the cleaning base station 2. The elastic reset member 33 is used to provide an elastic force to maintain the baffle 32 in the closed position. For example, the elastic reset member 33 can provide a supporting force to cover the dust collection port 22 when the baffle 32 is unloaded, or the elastic reset member 33 can provide a supporting force when the walking wheel 12 passes through the baffle 32. Under the suction of the negative pressure device, the baffle 32 can overcome the elastic force of the elastic reset member 33 and rotate to the open position.

[0081] Exemplarily, the suction force A of the negative pressure device, the support force B of the baffle 32, and the pressure C of the first running wheel 12 acting on the baffle 32 satisfy the relationship: A>B>C. In this way, when the running wheel 12 passes through the dust collecting port 22, since the support force B of the baffle 32 is greater than the pressure C of the first running wheel 12 acting on the baffle 32, the baffle 32 can support the running wheel 12 and keep the dust collecting port 22 blocked. After the running wheel 12 passes over the dust collecting port 22, and when the cleaning base station 2 collects dust, the negative pressure device works to provide suction. Since the suction force A of the negative pressure device is greater than the support force B of the baffle 32, the baffle 32 rotates toward the dust collecting port 22 under the action of the suction force A, thereby opening the dust collecting port, so that the dust collecting port 22 is connected to the dust outlet 11 of the cleaning robot 1, and then the cleaning base station 2 collects dust.

[0082] The present utility model embodiment further provides a cleaning base station 2 for the cleaning robot 1 to dock. The cleaning robot 1 has a garbage collection container and a dust outlet 11. The garbage collection container is connected to the dust outlet 11. The cleaning base station 2 includes:

[0083] The supporting base 21 is used to support the cleaning robot 1. A dust collecting port 22 is formed on the supporting base 21. The dust collecting port 22 is used to connect to the dust outlet 11 of the cleaning robot 1.

[0084] The travel assist mechanism 3 is disposed on the supporting seat 21 of the cleaning base station 2 . Along the direction in which the cleaning robot 1 enters the base station, the travel assist mechanism 3 is disposed outside the dust collecting port 22 and in front of the dust collecting port 22 .

[0085] The other structures and functions of the cleaning base station 2 of this embodiment can refer to the above-mentioned embodiment of the cleaning system, and will not be described in detail in this embodiment.
