[0036] Reference Figures 1 to 5, an embodiment of the present application proposes a cleaning device 10, which includes a dust cup assembly 100 and a body 200, and the dust cup assembly 100 is detachably mounted on the body 200, and the dust cup assembly 100 includes a side wall 110 and a bottom wall 120, wherein the side wall 110 and the bottom wall 120 enclose a dust chamber for accommodating dust, and the side wall 110 is provided with a dust discharge port 111, a flip cover 112, an elastic member 113 and a sealing member 114, and the dust discharge port 111 is connected to the dust chamber, and the flip cover 112 is movably arranged on the side wall 110 through the elastic member 113, and the sealing member 114 is arranged on the side of the flip cover 112 facing the dust discharge port 111, and the sealing member 114 is provided with a flange 1141, which abuts against part of the edge of the dust discharge port 111 to prevent dust from entering the area where the elastic member 113 is located when the flip cover 112 is opened or closed.
[0037] The cleaning device 10 provided in the embodiment of the present application has a flange 1141 provided on the sealing member 114 of the flip cover 112, so that the flange 1141 abuts against a portion of the edge of the dust discharge port 111. When the flip cover 112 is opened or closed, the gap between the flip cover 112 and the portion of the edge of the dust discharge port 111 is sealed, thereby preventing dust from entering the area where the elastic member 113 is located through the gap. Therefore, dust does not accumulate in the area where the elastic member 113 is located, thereby preventing dust from getting stuck. That is, the flip cover can be opened or closed normally, thereby not affecting the normal use of the cleaning device.
[0038] Specifically, when the cleaning device 10 cleans the surface to be cleaned, the fan in the main unit of the cleaning device 10 works, thereby generating negative pressure, so that the dust on the surface to be cleaned enters the dust chamber of the dust cup assembly 100 through the suction port of the main unit. When the dust in the dust chamber needs to be cleaned, the user places the cleaning device 10 on the maintenance base station 20, and the maintenance base station 20 generates negative pressure, such as Figures 4 to 7 As shown, under the action of the negative pressure, the flip cover 112 switches from a closed state to an open state, and the dust in the dust chamber is also discharged from the dust chamber under the action of the negative pressure, and enters the dust discharge channel of the maintenance base station 20 through the dust discharge port 111, and is finally collected in, for example, a dust collection bag of the maintenance base station. When the dust discharge operation is completed, the negative pressure generated by the maintenance base station 20 disappears, and the flip cover 112 switches from an open state to a closed state under the action of the elastic member 113. During the dust discharge process, since the seal 114 is arranged on the side of the flip cover 112 facing the dust discharge port 111, the seal 114 is provided with a flange 1141, and the flange 1141 abuts against a part of the edge of the dust discharge port 111, so as to seal the gap between the flip cover 112 and the part of the edge of the dust discharge port 111 when the flip cover 112 is opened or closed, thereby preventing dust from entering the area where the elastic member 113 is located. Therefore, dust will not accumulate in the area where the elastic member 113 is located, thereby avoiding the occurrence of dust jamming, that is, the flip cover 112 can be opened or closed normally, thereby not affecting the normal use of the cleaning device 10.
[0039] It should be noted that Figures 1 to 5 The dust cup assembly 100 shown in the figure is used for side dust extraction, that is, the dust in the dust chamber is discharged from the dust outlet 111 on the side wall to the maintenance base station 20. Of course, the technical solution of the dust cup assembly 100 provided in the embodiment of the present application can also be applied to the bottom flip dust extraction type dust cup. The specific structure can refer to the structure shown in the present application and will not be repeated here.
[0040] Further, refer to Figure 1 and Figure 3 In some embodiments of the present application, the seal 114 also includes a bottom plate 1142 and a connecting portion 1143, the flange 1141 is connected to the bottom plate 1142 through the connecting portion 1143, and the flange 1141 is obliquely arranged on the connecting portion 1143 to abut against a portion of the edge of the dust exhaust port 111.
[0041] As described above, the seal 114 is disposed on a side of the flip cover 112 facing the dust outlet 111. The seal 114 is provided with a flange 1141 that abuts against a portion of the edge of the dust outlet 111 to prevent dust from entering the area where the elastic member 113 is located when the flip cover 112 is opened or closed. Therefore, dust does not accumulate in the area where the elastic member 113 is located, thereby preventing dust from getting stuck. That is, the flip cover 112 can be opened or closed normally, thereby not affecting the normal use of the cleaning device 10. The flange 1141 of the seal 114 is connected to the bottom plate 1142 via a connecting portion 1143. Both the flange 1141 and the connecting portion 1143 are U-shaped. The flange 1141 is tilted on the connecting portion 1143 to abut against the side wall 110, thereby ensuring that the flange 1141 can closely abut against the side wall 110, thereby forming an effective sealing barrier, further preventing dust from entering the area where the elastic member 113 is located. The sealing member 114 is fixed to the flip cover 112 by snapping or bonding the bottom plate 1142 , thereby ensuring that the sealing member 114 can firmly abut against the side wall 110 to prevent dust from entering the area where the elastic member 113 is located.
[0042] Furthermore, in some embodiments of the present application, the bottom plate 1142 , the connecting portion 1143 and the flange 1141 of the sealing member 114 are an integrally formed flexible structure.
[0043] That is, the seal 114 is typically made of a flexible material such as silicone, and the bottom plate 1142, connecting portion 1143, and flange 1141 of the seal 114 are typically injection-molded or compression-molded from the silicone material. This ensures that the seal 114 can tightly contact the side wall 110, thereby forming an effective sealing barrier and further preventing dust from entering the area where the elastic member 113 is located. Furthermore, the above-described configuration of the seal 114 can simplify the manufacturing process and reduce manufacturing costs.
[0044] Further, refer again to Figures 1 to 7 In some embodiments of the present application, the flip cover 112 is further provided with a rib 1121, which is arranged on the side of the flip cover 112 facing the dust exhaust port 111. The rib 1121 abuts against the abutment portion of the side wall above the dust exhaust port 111 to prevent dust from entering the area where the elastic member 113 is located.
[0045] Specifically, if Figures 1 to 7 As shown, the function of the rib 1121 is to further prevent the dust discharged from the dust chamber through the dust outlet 111 from entering the area where the elastic member 113 is located. The rib 1121 is arranged on the side of the flip cover 112 facing the dust outlet 111, and the rib 1121 abuts against the abutment portion (such as a groove, etc.) of the side wall above the dust outlet 111, thereby effectively preventing dust from entering the area where the elastic member 113 is located. Therefore, dust will not accumulate in the area where the elastic member 113 is located, thereby avoiding the occurrence of dust jamming, that is, the flip cover 112 can be opened or closed normally, thereby not affecting the normal use of the cleaning device 10.
[0046] That is, when the cleaning device 10 cleans the surface to be cleaned, the fan in the main body of the cleaning device 10 works to generate negative pressure. At this time, the flip cover 112 is tightly attached to the side wall of the dust cup assembly under the action of the negative pressure; when the cleaning device 10 is placed on the maintenance base station 20 for dust removal operation, the fan of the maintenance base station 20 works to generate negative pressure. At this time, the dust in the dust chamber is discharged from the dust chamber under the action of the negative pressure, and the flip cover 112 will switch from a closed state to an open state under the action of the elastic member 113. The seal 114 is arranged on the side of the flip cover 112 facing the dust exhaust port 111. The seal 114 is provided with a flange 1141, which abuts against a portion of the edge of the dust exhaust port 111, and the flip cover 112 is also provided with a rib 1121, which abuts against the side wall above the dust exhaust port 111 to prevent dust from entering the area where the elastic member 113 is located when the flip cover 112 is opened or closed. Therefore, dust will not accumulate in the area where the elastic member 113 is located, thereby further avoiding the occurrence of dust jamming, that is, the flip cover 112 can be opened or closed normally, thereby not affecting the normal use of the cleaning device 10.
[0047] Further, refer to Figure 3 In some embodiments of the present application, the seal 114 is arranged below the rib 121, and the highest point of the flange 1141 of the seal 114 is lower than the plane where the rib 121 is located, so that when the flip cover 112 is opened or closed, the seal 114 and the rib 121 will not interfere with each other to hinder the opening or closing of the flip cover 112.
[0048] Furthermore, in some embodiments of the present application, the dust cup assembly 100 also includes a fixed cover 130, which, together with the side wall abutment portion and the flip cover 112, forms a cavity for accommodating the elastic member 113; or, the fixed cover 130, together with the rib 1121 and the flip cover 112, forms a cavity for accommodating the elastic member 113.
[0049] Specifically, the function of the fixed cover 130 is to isolate the elastic member 113 from the external space. It, together with the rib 1121 and the flip cover 112, forms a cavity for accommodating the elastic member 113, or together with the side wall abutment portion and the flip cover 112, forms a cavity for accommodating the elastic member 113, thereby preventing dust from accumulating in the area where the elastic member 113 is located, thereby further avoiding the occurrence of dust jamming, that is, the flip cover 112 can be opened or closed normally, thereby not affecting the normal use of the cleaning device 10.
[0050] Further, refer again to Figure 1 and Figure 3 In some embodiments of the present application, the flip cover 112 is also provided with a pivot portion 1122, and the side wall 110 is provided with a lug 115. The pivot portion 1122 of the flip cover 112 is snapped into the hole of the lug 115 of the side wall 110, so that the flip cover 112 can be movably set on the side wall 110 of the dust cup assembly 100.
[0051] That is, the flip cover 112 is a movable mechanism, and the pivot portion 1122 of the flip cover 112 is snapped into the hole of the lug 115 of the side wall 110, so as to ensure that the flip cover 112 is rotated in the hole of the lug 115 through the pivot portion 1122 under the action of the negative pressure generated by the dust chamber or the maintenance base station to perform an opening or closing operation for dust extraction or dust discharge operations.
[0052] Further, refer to Figure 1 and Figure 3 In some embodiments of the present application, the flip cover 112 further includes a cover plate 1123, and the rib 1121 and the pivot portion 1122 of the flip cover 112 are both arranged on the cover plate 1123, and the cover plate 1123, the rib 1121 and the pivot portion 1122 of the flip cover 112 are an integrally formed structure.
[0053] Specifically, in the dust box 100 provided in the embodiment of the present application, the cover plate 1123 of the flip cover 112 is primarily used to close the dust outlet 111 and to support the rib 1121 and the buckle portion of the flip cover 112, thereby ensuring that the dust outlet 111 can be effectively closed and that the cleaning device 10 can function properly. Furthermore, the flip cover 112 is typically made of a plastic material or a metal material, and the cover plate 1123, the rib 1121, and the pivot portion 1122 of the flip cover 112 are an integrally formed structure, that is, typically formed integrally from a plastic material or a metal material by casting or injection molding, resulting in a simple manufacturing process and low manufacturing cost.
[0054] Further, refer to Figure 1 The bottom plate 1142 of the seal 114 is detachably arranged on the cover plate 1123 of the flip cover 112, so that the seal 114 can be detachably fixed to the side of the flip cover 112 facing the dust exhaust port 111, and the bottom plate 1142 of the seal 114 is fixed to the cover plate 1123 of the flip cover 112 by a snap connection, so that the seal 114 can be removed from the flip cover 112 to replace the seal 114.
[0055] Of course, the bottom plate 1142 of the sealing member 114 may also be fixed to the cover plate 1123 of the flip cover 112 by bonding.
[0056] Further, refer to Figures 1 to 7 In some embodiments of the present application, the elastic member 113 is a spring, the side wall 110 is provided with a protrusion 116, and the flip cover 112 is provided with a snap-fitting portion 1124. One end of the spring 113 is snap-fitted to the protrusion of the side wall 110, and the other end of the spring 113 is snap-fitted to the snap-fitting portion of the flip cover 112.
[0057] Specifically, the elastic member 113 is usually a spring, one end of the spring is snap-connected to the protrusion 116 of the side wall 110, and the other end of the spring is snap-connected to the snap-connection portion 1124 of the flip cover 112. When the cleaning device 10 completes the dust removal operation, the negative pressure generated by the maintenance base station 20 disappears, and the flip cover 112 will be converted from an open state to a closed state under the action of the elastic member 113, thereby ensuring that the dust chamber is in a closed state, so that the cleaning device 10 can operate normally.
[0058] It should be noted that Figure 1 and Figure 2 The cleaning device 10 shown is a handheld vacuum cleaner, a handheld floor scrubber, a handheld floor sweeper, or a handheld integrated floor washer and sweeper. The cleaning device 10 may be wired or wireless, which is not limited herein. Figure 1 and Figure 2 The cleaning device 10 shown is only an example, and the specific structure of the cleaning device 10 is not limited thereto.
[0059] Reference Figures 4 to 7 The embodiment of the present application also provides a cleaning system 20, including a maintenance base station 30 and the cleaning device 10 as described above. The maintenance base station 30 is provided with a dust extraction port. When the cleaning device 10 is placed on the maintenance base station 30, the dust extraction port and the dust discharge port 111 of the cleaning device 10 are arranged opposite to each other. Under the action of negative pressure, the flip cover 112 of the cleaning device 10 opens, and the dust extraction port is connected to the dust chamber of the dust cup assembly 100 through the dust discharge port 111 to collect the dust in the dust chamber into the maintenance base station 30.
[0060] In the cleaning system 20, the structure of the cleaning device 10 refers to the above embodiment. Since the cleaning system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
[0061] like Figures 4 to 7 As shown, the dust exhaust port 111 and the dust extraction channel 31 of the maintenance base station 20 are arranged on the side of the dust cup assembly 100. In the cleaning system 20 provided in the embodiment of the present application, by arranging the dust extraction channel 31 on the outside of the peripheral side of the dust cup assembly 100, there is no need to occupy the usable space inside the dust cup assembly 100. At the same time, it can also prevent the obstruction of hair and the like due to the problem of usable space during the dust extraction process. In addition, the dust extraction channel 31 is arranged on the outside of the dust cup assembly 100, which can effectively utilize the space on the side of the dust cup assembly 100, increase the dust collecting capacity of the dust cup assembly 100, and effectively improve the use efficiency of the dust cup assembly 100.
[0062] Furthermore, a fixing groove is provided at the top of the dust extraction channel 31. The fixing cover 130 of the dust cup assembly 100 is snap-fitted into the fixing groove. As mentioned above, the function of the fixing cover 130 is to isolate the elastic member 113 from the external space. It is enclosed with the rib 1121 and the flip cover 112 to form a cavity for accommodating the elastic member 113, or is enclosed with the side wall abutment and the flip cover 112 to form a cavity for accommodating the elastic member 113, thereby preventing dust from accumulating in the area where the elastic member 113 is located. The fixing groove is used to snap-fit the fixing cover 130, thereby ensuring the stability and sealing of the fixing cover 130, further preventing dust from entering the interior of the fixing cover 130, and further avoiding the occurrence of dust jamming.
[0063] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application.
