[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] As people's living standards continue to improve, cleaning systems with cleaning devices and base stations are becoming more and more widely used. The cleaning devices are used to clean dust, paper scraps and other garbage on the work surface, and the base stations can charge the cleaning devices and suck up the garbage collected by the cleaning robots.

[0039] The base station is usually provided with a power supply system for charging the cleaning device and a suction system for sucking the garbage collected by the cleaning device. Correspondingly, the cleaning device is provided with a sewage suction pipe or sewage suction port connected to the sewage collecting chamber for docking and connection with the dust collecting port of the base station.

[0040] In the prior art, when the base station performs suction on the dirt collecting chamber, since the dirt collecting chamber has no air inlet passage, the outside air must enter the dirt collecting chamber through the dust suction port of the cleaning device or cannot enter the dirt collecting chamber. Among them, the passage from the dust suction port of the cleaning device to the dirt collecting chamber is complicated. Even if a small amount of air enters the dirt collecting chamber, it is difficult to form convection with the suction system of the base station, and the suction efficiency is low.

[0041] The present invention proposes a cleaning device 100, which is usually used in conjunction with a base station 200 in actual application scenarios. After the cleaning device 100 cleans the work surface, the cleaning device 100 and the base station 200 cooperate to vacuum and clean the dust, paper scraps and other garbage collected by the cleaning device 100. Figures 3 to 9 In an embodiment of the present invention, the cleaning device 100 includes a dust cup assembly 10 and a sealing assembly 20.

[0042] The dust cup assembly 10 is provided with a dirt collecting chamber 11, an air inlet channel 12 and a dirt extraction port 11a. The air inlet end 121a of the air inlet channel 12 is exposed on the surface of the dust cup assembly 10, the air outlet end 122b of the air inlet channel 12 is connected to the bottom of the dirt collecting chamber 11, and the dirt extraction port 11a is connected to the dirt collecting chamber 11. The dirt extraction port 11a is used to connect with the dust collecting port 220 of the base station 200.

[0043] In some embodiments, the dust cup assembly 10 is a cylindrical barrel, and in other embodiments, the dust cup assembly 10 is a prismatic barrel. The outer contour of the dust cup assembly 10 can specifically refer to the outer contour of the base station 200 used in conjunction with the cleaning device 100, so as to better cooperate with each other. Among them, the dust cup assembly 10 can be made of metal material, the dust cup assembly 10 can also be made of plastic with higher hardness, the dust cup assembly 10 can also be made of other materials, and the dust cup assembly 10 can also be made of a combination of multiple materials. In one manufacturing process, the dust cup assembly 10 can be integrally formed by injection molding. The present invention does not specifically limit the shape and material of the dust cup assembly 10.

[0044] The dirt collecting chamber 11 is used to temporarily store dust, paper scraps and other garbage collected by the cleaning device 100. After each work, the cleaning device 100 can cooperate with the base station 200. The dust collecting port 220 of the base station 200 is connected to the sewage extraction port 11a to clean the garbage in the dirt collecting chamber 11.

[0045] The dust cup assembly 10 may be provided with a variety of forms of the dirt collecting chamber 11. In one form of setting, a detachable dirt collecting box is provided in the dust cup assembly 10, and the dirt collecting chamber 11 is provided inside the dirt collecting box. With such a setting, the dirt collecting box can be removed from the dust cup assembly 10 by disassembling the dirt collecting box, and the dirt collecting chamber 11 can be cleaned, or a new dirt collecting box can be directly replaced, thereby avoiding the problem of residual garbage sticking to the dirt collecting chamber 11 after long-term use and being unable to be cleaned.

[0046] In another configuration, the dirt collecting chamber 11 is directly disposed on the inner wall of the dust cup assembly 10. This configuration can save the internal space of the dust cup assembly 10, increase the capacity of the dirt collecting chamber 11, increase the amount of garbage that can be stored in each operation of the cleaning device 100, and improve the working efficiency of the cleaning device 100. In order to prevent some stubborn garbage from adhering to the inner wall of the dust cup assembly 10, a protective film can be covered on the inner wall of the dust cup assembly 10. In another configuration, a dust bag can be disposed in the dust cup assembly 10.

[0047] The dust cup assembly 10 and the air inlet passage 12 may be integrally formed or separately formed. When separately formed, the two may be fixedly connected or detachably connected.

[0048] The blocking assembly 20 is movably connected to the dust cup assembly 10, and moves relative to the dust cup assembly 10 between an open position for opening the air inlet passage 12 and a closed position for closing the air inlet passage 12. The blocking assembly 20 is movably connected to the dust cup assembly 10, which can be a rotatable movably connected connection or a slidable movably connected connection.

[0049] In one configuration, the blocking assembly 20 includes an elastic reset member, which elastically abuts against the blocking assembly 20 so that the blocking assembly 20 has the power to close or open the air inlet passage 12. In another configuration, the base station 200 used in conjunction with the cleaning device 100 is provided with an opening mechanism, and the cleaning device 100 cooperates with the opening mechanism so that the blocking assembly 20 can close or open the air inlet passage 12.

[0050] Through the above technical scheme, the present invention provides a dirt collecting chamber 11, an air inlet channel 12 and a dirt extraction port 11a in the dust cup assembly 10, the air inlet end 121a of the air inlet channel 12 is exposed on the surface of the dust cup assembly 10, the air outlet end 122b of the air inlet channel 12 is connected with the bottom of the dirt collecting chamber 11, the external air can enter the dirt collecting chamber 11 through the air inlet channel 12, the dirt extraction port 11a is connected with the dirt collecting chamber 11, the blocking member 21 is movably connected to the dust cup assembly 10, and moves relative to the dust cup assembly 10 between an open position of opening the air inlet channel 12 and a closed position of closing the air inlet channel 12. With such arrangement, when the user operates the cleaning equipment to clean the work surface, the sealing component 20 closes the air inlet channel 12 to keep the dirt collecting chamber 11 in a relatively sealed state. When the user completes the cleaning work, the cleaning device 100 cooperates with the base station 200 to suck and clean the dust, paper scraps and other garbage collected by the cleaning device 100. The base station 200 cooperates with the sealing component 20 to make the sealing component 20 move from the closed position of closing the air inlet channel 20 to the open position of opening the air inlet channel 12. The outside air can enter the bottom of the dirt collecting chamber 11 through the air inlet channel 12, and the sewage extraction port 11a is connected to the dust collecting port 220 of the base station 200. The negative pressure generated by the base station 200 generates convection with the air outlet end 122b of the air inlet channel 12, so that the dust, paper scraps and other garbage can be sucked and cleaned from the bottom of the dirt collecting chamber 11 first, so as to improve the suction efficiency of the base station 200 on the dirt collecting chamber 11 in the dust cup assembly 10.

[0051] like Figures 3 to 5 As shown, the blocking assembly 20 includes a blocking member 21 and an elastic member 22. The blocking member 21 is provided with an abutting portion 211 for the base station 200 to abut against. The elastic member 22 drives the blocking member 21 to have a tendency to move from the open position to the closed position. With such a configuration, the structure of the cleaning device 100 is simple and reliable, and the manufacturing cost is lower than that of configuring an opening mechanism in the base station 200.

[0052] When the sealing component 20 and the dust cup component 10 are rotatably connected, the elastic member 22 may be a reset torsion spring, the base station 200 cooperates with the abutment top 211, the sealing component 21 rotates to open the air inlet channel 12, the base station 200 is separated from the abutment top 211, and the reset torsion spring provides elastic force for the sealing component 21 to rotate and close the air inlet channel 12. In this scheme, the sealing component 20 may be arranged on the outside of the dust cup component 10, and the base station 200 cooperates with the abutment top 211 using the lever principle. The sealing component 20 may also be arranged inside the dust cup component 10. This is a prior art and will not be described in detail.

[0053] In order to make the blocking member 21 close the air inlet passage 12 better, the blocking member 21 can be made of rubber materials, such as silicone rubber, EPDM rubber, polyurethane rubber, etc. The rubber material used to make the blocking member 21 is not specifically limited. At the same time, to ensure that the blocking member 21 has good vibration buffering, it can be made of one or more materials, and the blocking member 21 can also be set to a single-layer or multi-layer structure.

[0054] Considering that the cleaning device will cooperate with the base station 200 to suck and clean the garbage in the dirt collecting chamber 11 after each use, the blocking member 21 needs to frequently open or close the air inlet channel 12. Figure 5 , Figure 8 and Fig. 9 As shown, a mounting portion 141 is provided in the dust cup assembly 10, and the sealing assembly 20 is provided on the mounting portion 141. The elastic member 22 elastically abuts between the mounting portion 141 and the sealing member 21. The abutting top portion 211 is provided on the side of the sealing member 21 away from the elastic member 22. An avoidance portion 151 is provided at the bottom of the dust cup assembly 10. The base station 200 can pass through the avoidance portion 151 to abut against the abutting top portion 211. The sealing member 21 can slide relative to the dust cup assembly 10 in a direction close to or away from the mounting portion 141 to close or open the air inlet channel 12.

[0055] With such arrangement, the sliding movement of the blocking member 21 relative to the dust cup assembly 10 is simpler and more reliable, making the base station 200 and the abutment top 211 simple and easy to operate. The blocking assembly 20 is arranged inside the dust cup assembly 10, which also reduces the possibility of opening the air inlet passage 12 due to erroneous operation.

[0056] The dust cup assembly 10 is provided with a mounting portion 141 which can be an integral arrangement or a split arrangement. When the mounting portion 141 is a split arrangement, the two can be fixedly connected or detachably connected. In this embodiment, the mounting portion 141 is arranged in an arc shape or an annular shape, and is arranged on the inner peripheral wall adjacent to the bottom of the dust cup assembly 10. The blocking member 21 and the mounting portion 141 are arranged in an arc shape or an annular shape correspondingly. The elastic member 22 can be a sleeve spring, or a spring sheet. The elastic member 22 elastically abuts between the mounting portion 141 and the blocking member 21. The elastic member 22 always has a tendency to drive the blocking member 21 to move in a direction away from the mounting portion 141 to close the air inlet passage 12.

[0057] The elastic member 22 can drive the blocking member 21 to move along the inner wall of the dust cup assembly 10 in a direction away from the mounting portion 141, so as to drive the blocking member 21 to the opening of the air inlet channel 12 and close the air inlet channel 12. When the base station 200 passes through the avoidance portion 151 at the bottom of the dust cup assembly 10 and cooperates with the abutment portion 211, the base station 200 can drive the blocking member 21 to move along the inner wall of the dust cup assembly 10 in a direction close to the mounting portion 141, so as to drive the blocking member 21 to the opening away from the air inlet channel 12 and open the air inlet channel 12.

[0058] In one embodiment, a guide groove may be further provided on one side of the sealing member 21 facing the inner wall of the dust cup assembly 10, and a guide rail cooperating with the guide groove may be provided along the upper and lower protrusions of the inner wall of the dust cup assembly 10. Such a configuration can not only further ensure the sliding stability of the sealing member 21 relative to the dust cup assembly 10, but also enhance the strength of the dust cup assembly 10.

[0059] It can be understood that the mounting portion 141 can also be arranged on the bottom wall of the bottom of the dust cup assembly 10, and its arrangement form can also be similar to the above-mentioned method.

[0060] like Figure 5 and Figure 6 As shown, the elastic member 22 includes a plurality of springs, the mounting portion 141 is provided with a plurality of first positioning portions 142, and the side of the blocking member 21 away from the mounting portion 141 is provided with a plurality of second positioning portions 212, and the two ends of each spring are elastically abutted against the corresponding first positioning portion 142 and second positioning portion 212. Such a configuration facilitates the installation and positioning of the elastic member 22, improves the installation efficiency, and at the same time, due to the constraints of the first positioning portion 142 and the second positioning portion 212 on the spring, the spring is not easily offset when compressed, making the storage of elastic potential energy more reliable.

[0061] In one configuration, the first positioning portion 142 and the second positioning portion 212 are both truncated cone-shaped protrusions, and the spring is sleeved on the protrusions. In another configuration, the first positioning portion 142 and the second positioning portion 212 are both cylindrical grooves, and the two ends of the spring are elastically abutted against the bottom wall of the groove. In yet another embodiment, the first positioning portion 142 is a truncated cone-shaped protrusion, and the second positioning portion 212 is a cylindrical groove.

[0062] like Figures 4 to 6 As shown, the bottom of the dust cup assembly 10 is provided with a plurality of avoidance holes 151a to form an avoidance portion 151, and a plurality of protrusions 211a are provided on the side of the blocking member 21 away from the elastic member 22, and the plurality of protrusions 211a form abutment top portion 211, and each protrusion 211a cooperates with a corresponding avoidance hole 151a. Such a configuration makes it simple and easy to operate the base station 200 to cooperate with the protrusion 211a, and enhances the reliability of the base station 200 abutting against the protrusion 211a.

[0063] Each boss 211a and the blocking member 21 can be integrally or separately arranged. When separately arranged, the two can be fixedly connected or detachably connected. The blocking member 21 needs to frequently open or close the air inlet passage 12, so the boss 211a needs to frequently cooperate with the base station 200. A detachable connection solution can be preferred to facilitate maintenance or replacement of the boss 211a.

[0064] Each boss 211a is a cylindrical stepped shaft, and each avoidance hole 151a is a circular hole corresponding to the boss 211a. In some embodiments, the diameter of one end of each boss 211a away from the blocking member 21 is smaller than the diameter of the other end close to the blocking member 21. Each boss 211a can partially extend into the avoidance hole 151a to fit the gap and close the avoidance hole 151a.

[0065] like Figures 4 to 9 As shown, the air intake channel 12 includes a first channel 121 and a second channel 122, one end of the first channel 121 is exposed on the outer surface of the dust cup assembly 10, and the other end of the first channel 121 is arranged toward the blocking member 21, one end of the second channel 122 is connected to the dirt collecting chamber 11, and the other end of the second channel 122 is arranged toward the blocking member 21, wherein the blocking member 21 slides relative to the dust cup assembly 10 in a direction close to the mounting portion 141, and the first channel 121 is connected to the second channel 122 to open the air intake channel 12, and the blocking member 21 slides relative to the dust cup assembly 10 in a direction away from the mounting portion 141, blocking one end of the first channel 121 close to the blocking member 21 or / and one end of the second channel 122 close to the blocking member 21 to close the air intake channel 12.

[0066] In this embodiment, the first channel 121 is a plurality of through holes arranged at the bottom of the dust cup assembly 10, and the second channel 122 is a plurality of through holes connected to the dirt collecting chamber 11. Figure 5 , Figure 6 and Fig. 9 It can be seen that the second channel 122 includes two parts, one part is arranged in the vertical direction, and the other part is arranged in the horizontal direction. The two parts are connected to form the second channel 122, wherein a 90-degree angle is formed between the two parts of the second channel 122, and the second channel 122 is in an "L" shape. In other embodiments, the air intake channel 12 can be arranged in other forms, for example, the angle formed between the first channel 121 and the second channel 122 is in an "eight" shape.

[0067] like Figure 5 As shown, in this embodiment, the blocking member 21 is provided with a sealing head 213 to seal with the second channel 122 to close the air intake channel 12. In other embodiments, the blocking member 21 may be provided with a sealing head 213 to seal with the first channel 121.

[0068] like Figure 4 and Figure 5 As shown, the dust cup assembly 10 includes a dust cup 14 and a bottom plate 15 detachably disposed at the bottom of the dust cup 14, a first channel 121 and a second channel 122 are formed on the bottom plate 15, and a mounting portion 141 is disposed at the bottom of the dust cup 14. The bottom plate 15 can be connected to the dust cup 14 by a snap-fit ​​connection or by a threaded connection. In this configuration, the first channel 121 and the second channel 122 can be separated from the dust cup assembly 10 by disassembling the bottom plate 15, so as to maintain the air inlet channel 12.

[0069] The dust cup 14 and the bottom plate 15 can be manufactured by injection molding processes respectively, and separating the dust cup 14 and the bottom plate 15 also facilitates demoulding.

[0070] like Figure 3 and Figure 8 As shown, the sewage extraction port 11a is connected to the bottom of the sewage collection chamber 11, and the dust cup assembly 10 includes a sewage extraction pipe 13, the sewage inlet end 131 of the sewage extraction pipe 13 is connected to the sewage extraction port 11a, the sewage extraction pipe 13 is extended along the axial direction of the dust cup assembly 10, and the sewage outlet end 132 of the sewage extraction pipe 13 is exposed on the outer surface of the dust cup assembly 10 to connect and communicate with the dust collection port 220 of the base station 200. It can be understood that the setting of the sewage extraction pipe 13 can be similar to that of the air inlet channel 12. In a preferred embodiment, the sewage extraction pipe 13 is integrally provided with the dust cup assembly 10.

[0071] With such arrangement, the sewage inlet end 131 of the sewage extraction pipe 13 and the air outlet end 122b of the air inlet channel 12 generate convection, and the dust, paper scraps and other garbage in the sewage collecting chamber 11 can be directly sucked out through the sewage extraction pipe 13, further improving the cleaning efficiency of the base station 200 for the sewage collecting chamber 11.

[0072] In this embodiment, the sewage extraction pipe 13 is arranged on the outer periphery of the dust cup assembly 10. Such an arrangement can effectively utilize the outer peripheral space of the dust cup assembly 10, reserve more space for setting the dirt collection chamber 11, improve the working efficiency of the cleaning device 100, and also prevent the base station 200 from obstructing the hair due to space problems during the suction process of the dirt collection chamber 11.
