Abstract

The utility model provides a dust bag assembly and cleaning equipment. The dust bag assembly comprises a dust bag body and a fixing piece. Wherein the dust bag body comprises a breathable section and an airtight section which are communicated with each other, one end, far away from the breathable section, of the airtight section is an open end, and a first inlet is formed in the open end. The fixing piece is provided with a second inlet, and the fixing piece is connected with the opening end so that the first inlet can be communicated with the second inlet. Due to the fact that gas can only pass through the breathable section, garbage in the dust bag body can be driven by airflow to pass through the airtight section preferentially, is brought into the breathable section and is filled and gathered from the breathable bottom until the airtight section is filled, and therefore the situations that the opening of the dust bag is easily blocked by light garbage, and no garbage exists at the bottom of the dust bag actually are overcome. Therefore, the utilization rate of the space of the dust bag body is improved, and the frequency of dumping garbage in the dust bag or the frequency of replacing the dust bag by a user is reduced.

[0003] Based on this, a dust bag assembly and a cleaning device are provided that can meet the needs of users to extend the garbage disposal cycle or increase the dust bag replacement cycle.

[0004] The technical solution is as follows:

[0005] In one aspect, a dust bag assembly is provided, comprising:

[0006] A dust bag body, the dust bag body comprising a permeable section and an impermeable section which are interconnected, an end of the impermeable section away from the permeable section is configured as an open end, and the open end is provided with a first inlet; and

[0007] A fixing member is provided with a second inlet, and the fixing member is connected to the open end so that the first inlet is communicated with the second inlet.

[0013] In one embodiment, the airtight section is passed through the installation port, and the airtight section includes a connecting end for connecting the opening end and the airtight section. When the airtight section and the airtight section are both filled with garbage, the cross-sectional area of ​​the connecting end gradually decreases from the side of the connecting end close to the airtight section toward the side of the connecting end away from the airtight section. The cross-sectional area of ​​the airtight section is matched with the cross-sectional area of ​​the side of the connecting end close to the airtight section, and the cross-sectional area of ​​the opening end is matched with the cross-sectional area of ​​the side of the connecting end away from the airtight section.

When the dust suction function is needed, the air suction device is turned on, so that the garbage can pass through the dust suction port, the second inlet and the first inlet with the air flow and enter the dust bag body. Since the gas can only pass through the airtight section, the garbage in the dust bag body will preferentially pass through the airtight section and be brought into the airtight section under the influence of the air flow, and start to fill and gather from the bottom of the airtight section until it fills the airtight section. In this way, the situation that light garbage is easily blocked at the dust bag mouth while there is actually no garbage at the bottom of the dust bag is overcome, thereby improving the utilization rate of the dust bag body space, reducing the frequency of users emptying the dust bag garbage or reducing the frequency of replacing the dust bag.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] At present, the most advanced cleaning robots on the market are usually used in conjunction with workstations. In order to collect light solid waste such as dust and debris, dust bags are usually installed in the cleaning robots or workstations. In order to reduce the frequency of taking out garbage or replacing dust bags, end users have a strong demand for large-capacity dust bags. However, due to the limited space inside the robot body or the base station body, it is impossible to meet user needs by increasing the volume of the dust bag.

[0030] The inventor found that when users are ready to dump garbage or replace dust bags, they only see garbage piled up at the mouth of the dust bag, which makes users mistakenly think that the dust bag is "full" of garbage and needs to be dumped or replaced. However, after testing, the inventor found that at this time, the bottom of the dust bag is actually still empty, and only the mouth is full of garbage. In other words, the dust bag is not full of garbage at this time (the bottom is empty and the mouth is full), and the internal space of the dust bag originally designed to hold garbage is not fully utilized.

[0031] After careful research and analysis, the inventors found that the reason for the low space utilization of the dust bag is that the existing dust bag is made of a single material and is breathable at any position of the entire dust bag. When in use, light garbage (such as hair, flocs, dust, debris, etc.) is easily accumulated and blocked at the mouth of the dust bag, thereby reducing the effective volume of the dust bag and making the utilization rate of the dust bag low.

[0032] Based on this, the inventor has designed a dust bag assembly and a cleaning device that can meet the needs of users to extend the garbage disposal cycle or increase the dust bag replacement cycle, as shown in the various embodiments or implementations below.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a dust bag assembly 10 is provided, including a dust bag body 100 and a fixing member 200. The dust bag body 100 includes a permeable section 110 and an impermeable section 120 that are connected to each other, and one end of the impermeable section 120 away from the permeable section 110 is set as an open end 121, and the open end 121 is provided with a first inlet 122. The fixing member 200 is provided with a second inlet 211, and the fixing member 200 is connected to the open end 121 so that the first inlet 122 is connected with the second inlet 211.

[0034] When the dust bag assembly 10 in the above embodiment is used, the dust bag body 100 is installed on the air flow channel through the fixing member 200, so that the air flow carrying garbage can pass through the second inlet 211 and the first inlet 122 and enter the dust bag body 100. Since the gas can only pass through the air permeable section 110, the garbage in the dust bag body 100 will be driven by the air flow and preferentially pass through the airtight section 120 and be brought into the air permeable section 110, and start to fill and gather from the bottom of the air permeable section 110 until it fills the airtight section 120. In this way, the situation that light garbage is easily blocked at the mouth of the dust bag while there is actually no garbage at the bottom of the dust bag is overcome, thereby improving the utilization rate of the space of the dust bag body 100, reducing the frequency of users emptying the dust bag or reducing the frequency of replacing the dust bag.

[0035] Optionally, the breathable section 110 and the airtight section 120 are made of different materials, that is, the dust bag body 100 is a composite material dust bag. Specifically, the material of the breathable section 110 can be selected from non-woven fabrics, and non-woven fabrics of different filtration levels can be selected according to the customer's filtration requirements. The material of the airtight section 120 can be selected from a material that is airtight and has a higher hardness than the breathable section 110, such as a coated waterproof kraft paper or a waterproof kraft paper woven bag. Compared with a single material dust bag of the same volume, the composite material dust bag in the present application has a higher utilization rate. For some scenarios with relatively high environmental requirements (such as hospitals, pharmaceutical factories, etc.), when the dust bag is used as a disposable consumable, the high utilization rate of the composite material dust bag can save a lot of consumables costs.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the fixing member 200 is further provided with an installation opening 212 communicating with the second inlet 211, the inner side wall of the installation opening 212 is provided with a first connecting member 300, and the outer side wall of the opening end 121 is provided with a second connecting member 400, and the first connecting member 300 and the second connecting member 400 are detachably connected. In this way, the fixing member 200 and the dust bag body 100 are detachable, so as to facilitate the placement and replacement of the dust bag body 100, thereby improving the convenience and practicality of the dust bag assembly 10.

[0037] The number of the first connector 300 and the second connector 400 can be flexibly adjusted according to the actual use needs. Specifically in this embodiment, the number of the first connector 300 and the second connector 400 are both two, and each first connector 300 is detachably connected to each second connector 400. The first connector 300 and the second connector 400 can be detachably connected by plugging, snapping, hooking or other detachable connection methods.

[0038] like Figure 2 and Figure 3As shown, further, the first connecting member 300 is configured as a limiting card slot 310, and there are at least two limiting card slots 310, all of which are arranged on two inner side walls opposite to the installation opening 212; the second connecting member 400 is configured as a fixing card 410, and there are at least two fixing cards 410, all of which are arranged on two outer side walls opposite to the opening end 121, and each fixing card 410 is correspondingly engaged with each limiting card slot 310. In this way, there are multiple fixing points between the fixing member 200 and the dust bag body 100, so that the tension applied by the fixing member 200 to the dust bag body 100 is more evenly distributed, avoiding the situation that when the garbage accumulates to a certain extent, the garbage will sag or warp with the dust bag body 100 under the action of gravity to reduce the volume of the dust bag body 100, and ensuring that the opening end 121 can maintain an upright state to fill the garbage in the dust bag body 100 to the greatest extent, so as to improve the space utilization rate of the dust bag assembly 10.

[0039] Specifically in this embodiment, the limiting slot 310 extends along the axial direction of the installation opening 212. The fixing member 200 can be set as a fixing frame, and each limiting slot 310 is integrally formed with the fixing frame. The outer contour shape of the opening end 121 is adapted to the inner contour shape of the installation opening 212.

[0040] like Figure 2 and Figure 3 As shown, optionally, the second inlet 211 is communicated with any one of the two limiting slots 310, and the fixing card 410 near the second inlet 211 is provided with a third inlet 411 communicated with the first inlet 122, and when the two fixing cards 410 are correspondingly engaged with the two limiting slots 310, the third inlet 411 is communicated with the second inlet 211. In this way, the first sealing member 500 can keep the connection between the fixing card 410 and the fixing member 200 in a sealed state, prevent garbage from leaking from between the second inlet 211 and the third inlet 411, and improve the reliability of the dust bag assembly 10.

[0041] Specifically in this embodiment, the first sealing member 500 can be configured as a sealing ring or a sealing pad. The first sealing member 500 is located at a side of the fixing card 410 away from the opening end 121 and is correspondingly connected to the third inlet 411 .

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, the airtight section 120 is configured in a strip shape and can be bent. In this way, the shape of the dust bag body 100 can be adaptively adjusted according to actual use needs, so that the dust bag body 100 can be installed in boxes of different shapes, thereby improving the applicability of the dust bag assembly 10.

[0043] Specifically in this embodiment, the dust bag body 100 can be installed in a rectangular box or an L-shaped box through the fixing member 200. The airtight section 120 has a certain rigidity.

[0044] like Figure 1 and Figure 2 Optionally, the airtight section 120 is provided through the installation opening 212, and the airtight section 120 includes a connecting end 123 for connecting the opening end 121 and the airtight section 110. When the airtight section 110 and the airtight section 120 are both filled with garbage, the cross-sectional area of ​​the connecting end 123 gradually decreases from the side of the connecting end 123 close to the airtight section 110 toward the side of the connecting end 123 away from the airtight section 110, and the cross-sectional area of ​​the airtight section 110 is matched with the cross-sectional area of ​​the side of the connecting end 123 close to the airtight section 110, and the cross-sectional area of ​​the opening end 121 is matched with the cross-sectional area of ​​the side of the connecting end 123 away from the airtight section 110. In this way, it is ensured that the dust bag body 100 can be easily taken out from the installation opening 212 and the mouth of the box body after being filled with garbage, thereby improving the practicality and convenience of the dust bag assembly 10.

[0045] Specifically in this embodiment, the connection end 123 is designed to have a tapered structure, for example, the connection end 123 is designed to have a quadrangular pyramid structure. The opening end 121 and the air permeable section 110 are both designed to have a rectangular structure.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment, along the extension direction of the dust bag body 100 (such as Figure 1 In the direction shown by A in the figure), the ratio of the length of the air permeable section 110 to the length of the airtight section 120 is between 1:1 and 1:9. In this way, the air permeable area of ​​the air permeable section 110 can be kept within a suitable range, avoiding the air permeable area of ​​the air permeable section 110 being too small to meet the flow demand of the air suction device 30, and avoiding the air permeable section 110 being too large to expand excessively and unable to pass through the installation opening 212, thereby improving the reliability of the dust bag assembly 10.

[0047] The ratio of the length of the air permeable section 110 to the length of the airtight section 120 can be flexibly adjusted according to the actual use requirements. Specifically in this embodiment, the ratio of the length of the air permeable section 110 to the length of the airtight section 120 is 1:5. In other embodiments, the ratio of the length of the air permeable section 110 to the length of the airtight section 120 can also be 1:2, 1:3, 1:4, 1:6, 1:7 or 1:8, etc. The ratio of the length of the air permeable section 110 to the length of the airtight section 120 is also related to the filtration level required by the user.

[0048] like Figure 1 and Figure 2As shown, in one embodiment, the dust bag assembly 10 further includes an opening structure, which is disposed on the air permeable section 110 and can open or close the air permeable section 110. In this way, the user can open the air permeable section 110 through the opening structure and clean out the garbage in the dust bag body 100 through the air permeable section 110, so that the dust bag body 100 can be reused, thereby improving the practicality of the dust bag assembly 10.

[0049] The opening structure may be any structure in the prior art that can realize the opening and closing function, such as a zipper.

[0050] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, a cleaning device 1 is provided, including a device body 20, a suction device 30 and a dust bag assembly 10 in any of the above embodiments, the device body 20 is provided with a mounting cavity 21, and a dust suction port 22 and a suction port 23 both connected to the mounting cavity 21, the suction device 30 is connected to the suction port 23, and the dust bag assembly 10 is installed in the mounting cavity 21, so that the dust suction port 22, the second inlet 211, the first inlet 122, the airtight section 120, the air permeable section 110, the mounting cavity 21 and the suction port 23 are connected in sequence.

[0051] When the cleaning device 1 in the above embodiment is used, the dust bag body 100 is installed in the installation cavity 21 through the fixing member 200, so that the dust suction port 22, the second inlet 211, the first inlet 122, the airtight section 120, the airtight section 110, the installation cavity 21 and the air suction port 23 are connected in sequence. When the dust suction function is required, the air suction device 30 is turned on, so that the carried garbage can pass through the dust suction port 22, the second inlet 211 and the first inlet 122 with the air flow and enter the dust bag body 100. Since gas can only pass through the air permeable section 110, the garbage in the dust bag body 100 will preferentially pass through the impermeable section 120 driven by the air flow and be brought into the air permeable section 110, and start to fill and gather from the bottom of the air permeable section 110 away from the first inlet 122 until it fills the impermeable section 120. This overcomes the situation where light garbage is easily blocked at the mouth of the dust bag while there is actually no garbage at the bottom of the dust bag, thereby improving the space utilization rate of the dust bag body 100 and reducing the frequency of users dumping dust bag garbage or reducing the frequency of replacing dust bags.

[0052] It should be noted that the cleaning device 1 referred to in this application can be either a cleaning robot or a workstation used in conjunction with a cleaning robot, because in the field of household cleaning robots, a garbage recycling system including a dust bag is usually set on the workstation to recycle and empty the garbage temporarily stored in the dust box inside the cleaning robot, while in the field of commercial cleaning robots, the dust bag is usually set directly in the recycling box on the cleaning robot body. The cleaning device 1 can also be a vacuum cleaner, a floor scrubber or other products with a vacuuming function. The cleaning device 1 provided in this application is only illustrated by taking a cleaning robot as an example, and is not limited to a cleaning robot. Of course, it should be noted that the cleaning device 1 in the accompanying drawings is only a partial structure of the cleaning robot, not the complete structure.

[0053] Optionally, the dust bag assembly 10 further includes a second sealing member 600, which is disposed between the fixing member 200 and the inner wall of the mounting cavity 21 and is used to seal and connect the dust suction port 22 with the second inlet 211. Specifically in this embodiment, the second sealing member 600 can be configured as a sealing ring or a sealing pad. The air suction device 30 can be configured as a centrifugal fan, which is connected to the air suction port 23 through an air suction pipe.
