These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0046] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] Combination Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a dust collection assembly, which includes a dust collection box 100 and a flexible bag 200.

[0048] The dust collection box 100 has a dust collection chamber 110, and the dust collection chamber 110 is provided with a dust inlet 111. A flexible bag 200 is located inside the dust collection chamber 110. The flexible bag 200 has a first opening 210 and a second opening 220. The first opening 210 communicates with the dust inlet 111, and the second opening 220 communicates with the dust collection chamber 110.

[0049] Among them, such as Figure 1 As shown, when airflow flows from the dust inlet 111 into the dust collection chamber 110, the flexible bag 200 is inflated, and the target object enters the dust collection chamber 110 through the flexible bag 200. In this way, the dust collection box 100 can fulfill its function of collecting the target object. Figure 2 As shown, when no airflow flows from the dust inlet 111 into the dust collection chamber 110, the flexible bag 200 is in a hanging state, covering the dust inlet 111. This prevents the target object inside the dust collection box 100 from leaking out of the dust inlet 111. It should be noted that the target object in this embodiment is garbage, impurities, dust, etc.

[0050] Because the flexible bag 200 has very low rigidity, it is not easy for the flexible bag 200 to be stuck by garbage or other target objects during the dust collection process of the dust collection box 100. Therefore, when the dust collection box 100 stops collecting dust, it can ensure that the flexible bag 200 can be in a state of hanging down and covering the dust inlet 111, thereby ensuring that garbage or other objects will not leak out from the dust inlet 111.

[0051] The following is in conjunction with the appendix Figures 1 to 7 The details and functions of the dust collection components provided in the embodiments of this application will be described in more specific and detailed manner.

[0052] like Figure 1 As shown, in some embodiments, the edge of the first opening 210 surrounds the dust inlet 111. This arrangement allows for better sealing of the dust inlet 111.

[0053] like Figure 1 As shown, in some embodiments, the dust inlet 111 is formed on the first sidewall 120 of the dust collection box 100, and the edge of the first opening 210 is connected to the first sidewall 120 by at least one of the following methods: bonding, fastening, and clamping. This allows the flexible bag 200 to be more stably connected to the dust collection box 100. Bonding methods include, for example, using double-sided adhesive; fastening methods include, for example, using bolts or other fasteners; and clamping methods include, for example, using clips or similar devices to clamp the flexible bag 200 to the sidewall of the dust collection box 100.

[0054] Combination Figure 2In some embodiments, the second opening 220 is arranged to face the first side wall 120 when the flexible bag 200 is in the hanging state. That is, when the flexible bag 200 is in the hanging state, the second opening 220 is blocked by the wall surface of the first side wall 120, so as to ensure that the garbage and other objects in the dust collecting box 100 cannot leak out of the dust collecting box 100 from the second opening 220. As shown in Figure 3 In some embodiments, the second opening 220 is arranged to face the first side wall 120 when the flexible bag 200 is in the hanging state. That is, when the flexible bag 200 is in the hanging state, the second opening 220 is blocked by the wall surface of the first side wall 120, so as to ensure that the garbage and other objects in the dust collecting box 100 cannot leak out of the dust collecting box 100 from the second opening 220. As shown in

[0055] In some embodiments, the second opening 220 is arranged to face the first side wall 120 when the flexible bag 200 is in the hanging state. That is, when the flexible bag 200 is in the hanging state, the second opening 220 is blocked by the wall surface of the first side wall 120, so as to ensure that the garbage and other objects in the dust collecting box 100 cannot leak out of the dust collecting box 100 from the second opening 220. As shown in Figure 2 In some embodiments, the second opening 220 is arranged to face the first side wall 120 when the flexible bag 200 is in the hanging state. That is, when the flexible bag 200 is in the hanging state, the second opening 220 is blocked by the wall surface of the first side wall 120, so as to ensure that the garbage and other objects in the dust collecting box 100 cannot leak out of the dust collecting box 100 from the second opening 220. As shown in

[0056] In some embodiments, the second opening 220 is arranged to face the first side wall 120 when the flexible bag 200 is in the hanging state. That is, when the flexible bag 200 is in the hanging state, the second opening 220 is blocked by the wall surface of the first side wall 120, so as to ensure that the garbage and other objects in the dust collecting box 100 cannot leak out of the dust collecting box 100 from the second opening 220. As shown in Figure 1 In some embodiments, the dust collecting assembly further comprises a baffle 300, one side of the baffle 300 is rotatably connected with the first side wall 120, and the flexible bag 200 is located between the first side wall 120 and the baffle 300. When the airflow stops flowing, the baffle 300 covers the flexible bag 200. It should be noted that, since the baffle 300 is heavier than the flexible bag 200, when the airflow stops flowing, the baffle 300 can press the flexible bag 200 to adhere to the first side wall 120, so as to better seal the dust inlet 111, thereby preventing the garbage and other objects in the dust collecting box 100 from leaking out.

[0057] In some embodiments, when the baffle 300 covers the flexible bag 200, the baffle 300 covers the dust inlet 111 in the first side wall 120. In this way, when the baffle 300 falls, the dust inlet 111 can be completely sealed, so as to improve the sealing performance of the dust collecting box 100 when the airflow stops flowing, and further ensure that the garbage and other objects in the dust collecting box 100 do not leak out. Figure 1 ​

[0058] As shown in Figure 1 some embodiments, the first side wall 120 is provided with an attaching portion 121 for detachable attachment of the flexible bag 200. Thus, when the flexible bag 200 is hanging down, it can be better attached to the first side wall 120 to cover the dust inlet 111, improving the sealing of the dust collecting box 100.

[0059] As shown in Figure 1 , Figure 2 and Figure 5 some embodiments, the dust collecting box 100 comprises a first shell 130 and a second shell 140, which are buckled to form the dust collecting cavity 110. The first shell 130 is provided with the dust inlet 111. The second shell 140 is provided with the air vent 141, wherein the flexible bag 200 is inflated when air flows from the dust inlet 111 to the air vent 141. It should be noted that the first shell 130 comprises the first side wall 120 and other side walls connected to the plurality of first side walls 120. The outer side adjacent to the air vent 141 can be provided with the fan 400, which can form negative pressure in the dust collecting box 100 when working, and at this time, the flexible bag 200 is in an inflated state, and air can flow from the dust inlet 111 to the air vent 141 through the flexible bag 200. Figure 1 and Figure 4 As shown in some embodiments, when the flexible bag 200 is in the inflated state, the second opening 220 faces the air vent 141, so that the garbage and other objects can more easily enter the dust collecting box 100 along the air flow direction A1. In other embodiments, when the flexible bag 200 is in the inflated state, the second opening 220 can face both the air vent 141 and the first side wall 120, so as to ensure the sealing of the flexible bag 200 when falling down, and also to facilitate the garbage and other objects to enter the dust collecting box 100 along the air flow direction A1.

[0060] Figure 7 As shown in some embodiments, the air vent 141 is provided with a filter 600, a first reinforcing member 700 and a second reinforcing member 800. The filter 600 covers the air vent 141. The surface of the filter 600 facing the inside of the dust collecting box 100 is connected to the first reinforcing member 700, and the surface of the filter 600 facing away from the inside of the dust collecting box 100 is connected to the second reinforcing member 800. It can be understood that the filter 600 can play a filtering role to prevent garbage and other objects in the dust collecting cavity 110 from leaking out of the air vent 141. The filter 600 in the embodiments of the present application can be, for example, a filter screen or other component with a filtering function. The first reinforcing member 700 and the second reinforcing member 800 can respectively support the two sides of the filter 600 to increase the strength of the filter 600. The first reinforcing member 700 and the second reinforcing member 800 can respectively be formed by reinforcing ribs that cross and connect to each other.

[0061] Combination Figures 1 to 7 As shown, on the other hand, this application embodiment also provides a cleaning device, which includes a dust collection component as described above. It should be noted that the dust collection component in the cleaning device of this application embodiment has the same composition and function as the dust collection component in the above-described embodiments of this application, therefore, it will not be described again here. The cleaning device can be a robot vacuum cleaner or other device with cleaning and dust collection functions. Since the dust collection component ensures that the dust collection box 100 does not leak out garbage or other objects, it can prevent garbage from falling from the dust collection box 100 to the ground when the cleaning device stops working.

[0062] like Figure 6 As shown, in some embodiments, the cleaning equipment may also include a fan 400. Generally, the fan 400 can be installed on the outer side adjacent to the vent 141. When the fan 400 is working, it can create a negative pressure inside the dust collection box 100. At this time, the flexible bag 200 is in a bulging state, and the airflow can flow from the dust inlet 111 through the flexible bag 200 to the vent 141, so that garbage and other objects can enter into the dust collection box 100.

[0063] like Figure 6 As shown, in some embodiments, the cleaning device may further include a cleaning component 500, which is installed adjacent to the dust inlet 111. The cleaning component 500 may be, for example, a roller brush or a mop. By placing the cleaning component 500 near the dust inlet 111, when the cleaning component 500 rotates, it is easier to deliver target objects such as garbage to the dust inlet 111, making it easier for garbage to enter the dust collection box 100 and improving the dust collection efficiency of the cleaning device.
