[0041] Currently, the dust bags of cleaning equipment on the market are disposable dust bags and cannot be recycled and reused. This requires users to replace the disposable dust bags, thereby increasing the user's usage costs and wasting a lot of manufacturing material resources.
[0042] Please also read Figures 1 to 3 The utility model proposes a dust bag 1000, which can be used for cleaning a base station, a cleaning robot, or a handheld cleaning device, and no specific limitation is made here.
[0043] The dust bag 1000 includes a bag body 100 and a connecting assembly 200. The bag body 100 can have many shapes. The bag body 100 can be square, round, or other shapes, which are not specifically limited here. The bag body 100 can be fixed in shape by setting a bracket 300. The bag body 100 can also be a flexible irregular shape, which is not specifically limited here. The bag body 100 can be made of many materials. The bag body 100 can be made of plastic material, cloth, or cardboard, which are not specifically limited here.
[0044] The bag body 100 is provided with a accommodating chamber 110, a dust inlet 120 and a dust outlet 130. The accommodating chamber 110 has many shapes, and the shape of the accommodating chamber 110 can be square, circular, or other shapes, which are not specifically limited here. Preferably, the shape of the accommodating chamber 110 is the same as the shape of the bag body 100, so that the volume of the accommodating chamber 110 can be maximized.
[0045] The dust inlet 120 and the dust outlet 130 are both connected to the accommodating chamber 110. The dust inlet 120 and the dust outlet 130 can have various shapes. The dust inlet 120 and the dust outlet 130 can be circular, square, or other shapes, which are not specifically limited here.
[0046] The bag body 100 is provided with an extension part 140 on the peripheral side of the dust outlet 130, and the extension part 140 is used to seal or open the dust outlet 130 through the connection component 200.

It should be noted that the extension part 140 is a flexible part 600, and the extension part 140 can move relative to the bag body 100, so as to open or cover the dust outlet 130.
[0047] It should also be noted that the dust inlet 120 can be arranged on the extension part 140. After the dust outlet 130 is covered by the extension part 140, it is connected with the external environment only through the dust inlet 120, so that garbage can only enter the containing cavity 110 from the dust inlet 120, thereby achieving the dust collection effect.
[0048] When the dust bag 1000 needs to be cleaned, the dust bag 1000 is first taken out, then the connector is opened, and then the extension part 140 is opened to expose the dust outlet 130, and finally the garbage in the accommodating cavity 110 is cleaned through the dust outlet 130. When the dust bag 1000 needs to be used, the dust outlet 130 is first covered by the extension part 140, and then the connector is closed, and finally the dust bag 1000 is installed at a designated position.
[0049] The technical solution of the utility model adopts an extension part 140 to be arranged at the dust outlet 130, and the extension part 140 seals or opens the dust outlet 130 through the connecting component 200. In this way, the extension part 140 can be opened through the connecting component 200, so that the garbage in the accommodating cavity 110 can be cleaned through the dust outlet 130, so that the dust bag 1000 can be reused, which reduces the user's use cost and reduces the waste of manufacturing material resources. At the same time, the extension part 140 formed by the bag body 100 extends to cover the dust outlet 130, thereby reducing the setting of parts, thereby facilitating user operation, and improving the overall assembly efficiency of the dust bag 1000.
[0050] Please also read Figures 1 to 3In some embodiments of the present invention, the connection assembly 200 includes an adhesive cloth 210 and a Velcro 220. The adhesive cloth 210 is disposed on the bag body 100 and is disposed around the dust outlet 130. The Velcro 220 is disposed on the side of the extension part 140 facing the dust outlet 130. When the extension part 140 seals the dust outlet 130, the Velcro 220 is connected to the adhesive cloth 210. In this way, the adhesive cloth 210 and the Velcro 220 can cooperate to seal the gap between the extension part 140 and the bag body 100, thereby preventing the garbage in the accommodating cavity 110 from flying out of the gap between the extension part 140 and the bag body 100 to cause pollution to the external environment.
[0051] It should be noted that the adhesive cloth 210 can be partially connected to the bag body 100 and partially suspended on the dust outlet 130 to partially cover the dust outlet 130. The Velcro 220 is connected to the part of the adhesive cloth 210 suspended on the dust outlet 130. The adhesive cloth 210 can also be completely connected to the bag body 100. The Velcro 220 is partially connected to the extension part 140 and partially extends out of the extension part 140. The part of the Velcro 220 extending out of the extension part 140 is connected to the adhesive cloth 210. No specific limitation is made here.
[0052] There are many ways to connect the adhesive cloth 210 to the bag body 100. The adhesive cloth 210 can be connected to the bag body 100 by sewing, ultrasonic welding, or other methods, which are not specifically limited here. There are many ways to connect the Velcro 220 to the extension part 140. The Velcro 220 can be connected to the extension part 140 by sewing, gluing, or other methods, which are not specifically limited here.
[0053] For details, please refer to Figures 1 to 3 The surface of the extension part 140 facing the dust outlet 130 is convexly provided with a sealing part 141, and the sealing part 141 extends along the circumference of the extension part 140, so that the sealing part 141 is set in a U shape, and the Velcro 220 is set on the inner wall surface of the sealing part 141. In this way, the Velcro 220 can be completely connected with the sealing part 141, and the adhesive cloth 210 can be completely connected with the bag body 100, thereby increasing the adhesion area of the Velcro 220 and the adhesive cloth 210, so that the extension part 140 can seal the dust outlet 130 more stably, and at the same time, the setting of the sealing part 141 can increase the contact area between the extension part 140 and the bag body 100, so as to better prevent the garbage in the accommodating cavity 110 from causing secondary pollution to the external environment.
[0054] Please also refer to Figures 1 to 3 When the extension part 140 seals the dust outlet 130, the distance from the end of the adhesive cloth 210 away from the extension part 140 to the extension part 140 is greater than the length of the sealing part 141, so that the adhesive cloth 210 is exposed. In this way, the edge of the adhesive cloth 210 will exceed the edge of the sealing part 141, so that when the extension part 140 seals the dust outlet 130, it can play a role in blocking garbage and preventing leakage, thereby preventing the garbage in the accommodating chamber 110 from causing secondary pollution to the external environment.
[0055] Please also read Figures 4 to 5 In some embodiments of the present invention, the connection component 200 is a zipper 230, and the two sides of the zipper 230 are respectively located on the peripheral wall of the dust outlet 130 and the peripheral wall of the extension 140, so that the dust outlet 130 can be opened or sealed by closing or opening the two sides of the zipper 230. In this way, the dust outlet 130 can be sealed by closing the zipper 230, and the dust outlet 130 can be opened by opening the zipper 230, so that the user can operate it conveniently.
[0056] Considering that there is a gap between the teeth of the zipper 230 after the teeth are engaged, the garbage in the receiving chamber 110 is easily passed through the gap between the teeth to cause secondary pollution to the external environment. In view of this, please refer to Figures 4 to 5 The bag body 100 is provided with a shielding cloth 150, which is arranged around the dust outlet 130, so that when the extension part 140 seals the dust outlet 130, the shielding cloth 150 shields the zipper 230. In this way, the shielding cloth 150 shields the zipper 230, thereby shielding the gap between the teeth of the zipper 230, thereby preventing the garbage in the accommodating cavity 110 from causing secondary pollution to the external environment through the gap between the teeth.
[0057] When the user needs to clean the dust bag 1000, the user first takes out the dust bag 1000, then lifts the shielding cloth 150 to expose the zipper 230, then unzips the zipper 230 to open the extension 140 to expose the dust outlet 130, and finally cleans the garbage in the accommodating cavity 110 through the dust outlet 130. When the user needs to use the dust bag 1000, the user first closes the zipper 230, then moves the shielding cloth 150 to cover the zipper 230, and finally installs the dust bag 1000 in a designated position.
[0058] Please also read Figures 1 to 5In some embodiments of the present invention, the dust outlet 130 and the dust inlet 120 are respectively located at two opposite walls of the accommodating cavity 110. In this way, the dust outlet 130 and the dust inlet 120 are spaced far apart, thereby avoiding interference between the connecting assembly 200 and the parts at the dust inlet 120, and also avoiding interference between the parts at the connecting position of the connecting assembly 200 and the dust inlet 120 when the dust bag 1000 is installed at the designated position, thereby facilitating the user to install the dust bag 1000 at the designated position.
[0059] Please also read Figures 1 to 3 In some embodiments of the utility model, the dust bag 1000 also includes a bracket 300 and a handle 400. The bracket 300 is penetrated by a through hole 310. The bracket 300 is installed on the dust inlet 120, and the through hole 310 is connected with the dust outlet 130; the handle 400 is penetrated by a connecting hole 410. The handle 400 is movably installed on the bracket 300. The handle 400 has an open position and a closed position. When the handle 400 is in the open position, the connecting hole 410 is connected with the through hole 310; when the handle 400 is in the closed position, the handle 400 blocks the through hole 310.
[0060] With such a configuration, the user can lift the dust bag 1000 by the handle 400, thereby facilitating the user to take the dust bag 1000. At the same time, the handle 400 will switch from an open position to a closed position, thereby preventing the garbage in the accommodating chamber 110 from causing secondary pollution to the external environment through the dust inlet 120 when the dust bag 1000 is taken out. When the dust bag 1000 is in use, the handle 400 switches to an open position, thereby allowing the garbage to enter the accommodating chamber 110 through the connecting hole 410, the through hole 310 and the dust inlet 120 in sequence, thereby not affecting the use of the dust inlet 120.
[0061] The bracket 300 can be made of many materials, such as metal, wood, or hard plastic, which are not specifically limited here. The handle 400 can be made of many materials, such as metal, wood, or hard plastic, which are not specifically limited here.
[0062] It should be noted that when the handle 400 is in the open position, the handle 400 partially extends out of the bracket 300, so that the user can extend the bracket 300 from the handle 400 to lift it. At the same time, the closed position is located above the open position. Therefore, when the user lifts the handle 400, the handle 400 will exert a lifting force and the bracket 300 will be affected by gravity, so that the handle 400 switches to the closed position, thereby preventing the handle 400 from switching to the open position during the lifting process. In this way, when the user lifts the handle 400, the handle 400 can be stably located in the closed position, preventing the garbage in the accommodating chamber 110 from causing secondary pollution to the external environment through the dust inlet 120.
[0063] Furthermore, the bracket 300 is provided with a limiting groove, and the handle 400 is provided with a limiting protrusion, which extends into the limiting groove. When the handle 400 is in a closed position, the limiting protrusion abuts against the groove wall of the limiting groove. Such a configuration can prevent the handle 400 from being separated from the bracket 300 due to a large pulling force, causing the bag body 100 to fall to the ground.
[0064] Please also read Figures 1 to 3 In some embodiments of the present invention, the dust bag 1000 also includes a sealing ring 500, which is located between the bracket 300 and the handle 400. The sealing ring 500 is arranged around the through hole 310. In this way, the sealing ring 500 seals the gap between the handle 400 and the bracket 300, thereby preventing the garbage in the accommodating cavity 110 from passing through the dust inlet 120 and the gap between the bracket 300 and the handle 400 to cause secondary pollution to the external environment.
[0065] Please also read Figures 1 to 3 In some embodiments of the present invention, the dust bag 1000 further includes a flexible member 600, which is mounted on a side of the handle 400 away from the bracket 300, and the flexible member 600 is arranged around the connecting hole 410. In this way, the gap between the handle 400 and the installation position is sealed by the flexible member 600, thereby preventing garbage from leaking through the gap between the handle 400 and the installation position, causing secondary pollution to the external environment.
[0066] The utility model also proposes a cleaning device (not shown), which includes a dust bag 1000. The specific structure of the dust bag 1000 refers to the above embodiment.
