[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the prior art, a circle of the dust bag body 100 around the entrance 111 is directly bonded to a board frame 210 made of cardboard, and a portion of the board frame 210 away from the entrance 111 is used for detachable connection with the cleaning device, wherein the surface paper of the board frame 210 around the entrance 111 is prone to poor glue adhesion and is also prone to breakage and fall off the board frame 210. In particular, in a humid environment, the strength of the board frame 210 decreases, making it more likely that the surface paper bonded to the dust bag will break and fall off.

[0032] Reference Figures 1 to 3 According to a first embodiment of the present invention, a dust bag comprises a dust bag body 100, a plate frame 210 made of cardboard and a valve plate 400. The dust bag body 100 is provided with a accommodating cavity 110 and an inlet 111 connected to the accommodating cavity 110; the plate frame 210 is located at the inlet 111, and the plate frame 210 is provided with a first avoidance hole 211 opposite to the inlet 111. A plastic film 300 is attached to the surface of the plate frame 210 facing the dust bag body 100, the plastic film 300 is fixedly connected to the plate frame 210, the plastic film 300 is bonded to the dust bag body 100, and the plastic film 300 is provided with a second avoidance hole 310 opposite to the inlet 111.

[0033] The plastic film 300 is attached and fixedly connected to the surface of the plate frame 210 facing the dust bag body 100, and then the plastic film 300 is bonded to the dust bag body 100, so that the plate frame 210 is fixed to the dust bag body 100. Compared with the prior art, the plastic film 300 is easier to bond to the dust bag body 100 and has a higher bonding strength. Compared with the surface paper of the plate frame 210, the plastic film 300 itself is not easy to be partially broken and fall off. Also affected by the humid environment, the connection strength between the plastic film 300 and the surface of the plate frame 210 facing the dust bag body 100 can also be higher, thereby improving the connection strength between the plate frame 210 made of cardboard and the dust bag body 100, effectively reducing the situation that the plate frame 210 is separated from the dust bag body 100. In addition, the provision of the plastic film 300 can also improve the overall strength of the plate frame 210, making the plate frame 210 not easy to bend, and reducing the situation that the plate frame 210 is damaged.

[0034] According to some embodiments of the utility model, the plastic film 300 is bonded to the plate frame 210. Specifically, the plastic film 300 and the entire surface of the plate frame 210 facing the dust bag body 100 are bonded together as closely as possible. Therefore, compared with the prior art in which only the portion of the plate frame 210 close to the inlet 111 is bonded to the dust bag body 100, the bonding area between the plastic film 300 and the plate frame 210 is large, the connection strength between the plastic film 300 and the plate frame 210 is higher, and it is not easy for the surface paper of the plate frame 210 to break and fall off, thereby reducing the situation in which the plate frame 210 separates from the dust bag body 100.

[0035] It is conceivable that, in other embodiments, the plastic film 300 may be fixedly connected to the plate frame 210 in other ways. For example, the plastic film 300 and the plate frame 210 may be riveted and pressed together by a plurality of rivet structures.

[0036] In the specific implementation process, by controlling the thickness of the plastic film 300, the consumables of the plastic film 300 are controlled while ensuring that the strength of the plastic film 300 is sufficient, thereby controlling the overall cost of the dust bag. According to some embodiments of the utility model, the thickness of the plastic film 300 is less than 1 mm, so that the thickness of the plastic film 300 is not too thick, and the plastic film 300 causes less increase in the cost of the dust bag.

[0037] Reference Figures 1 to 4 According to some embodiments of the present invention, the dust bag includes a valve plate 400, which is slidably disposed on the plate frame 210, wherein the valve plate 400 is used to open and close the inlet 111. Thus, the inlet 111 can be opened and closed by sliding the valve plate 400.

[0038] In the existing dust collecting bag, two partitions are usually glued to the plate frame 210, and then the cover plate 220 is glued to the two partitions, so that the plate frame 210, the cover plate 220 and the two partitions are surrounded by a receiving groove 230, and the valve plate 400 is inserted into the receiving groove 230. This arrangement requires more parts for the dust collecting bag and more assembly steps, which is not conducive to improving production efficiency.

[0039] For this purpose, refer to Figure 1 and Figure 2 According to some embodiments of the utility model, a cover plate 220 is included, the cover plate 220 is arranged opposite to the plate frame 210, the cover plate 220 is connected to the plate frame 210, the cover plate 220 and the plate frame 210 are enclosed to form a receiving groove 230, the valve plate 400 is slidably inserted in the receiving groove 230, and the cover plate 220 is provided with a third avoidance hole 221 opposite to the first avoidance hole 211. Therefore, the dust bag provided in the present application is directly enclosed by the cover plate 220 and the plate frame 210 to form the receiving groove 230, eliminating the setting of the partition, simplifying the structure, streamlining the assembly steps, and being conducive to improving production efficiency. Among them, in the mass production process. The assembly process between the plastic film 300 and the plate frame 210, and the assembly process between the plate frame 210 and the cover plate 220 can be completed simultaneously.

[0040] Reference Figure 1 , Figure 4 and Figure 5 According to some embodiments of the utility model, the accommodating groove 230 is connected to the limiting groove 240, and the valve plate 400 is provided with a clamping block 410, which is located in the limiting groove 240. The clamping block 410 cooperates with the side wall of the limiting groove 240 to limit the sliding range of the valve plate 400, thereby preventing the valve plate 400 from being separated from the accommodating groove 230, and also facilitating the user to repeatedly operate the valve plate 400 to open and close the entrance 111.

[0041] Reference Figure 4 and Figure 5 According to some embodiments of the utility model, the surface of the plate frame 210 facing the cover plate 220 is formed with a first pressing groove 212 and a second pressing groove 213. The side wall of the first pressing groove 212 and the cover plate 220 are enclosed to form a receiving groove 230, and the second pressing groove 213 and the cover plate 220 are enclosed to form a limiting groove 240. The first pressing groove 212 and the second pressing groove 213 can be stamped and formed on the plate frame 210 at the same time through a stamping process, which is convenient to process, with high production efficiency and low cost. In addition, the cover plate 220 does not need to be additionally processed with structures such as grooves, and the cover plate 220 remains in a flat shape to ensure the appearance of the dust bag.

[0042] Reference Figure 1 , Figure 4 and Figure 5According to some embodiments of the present invention, the valve plate 400 is provided with a valve hole 420 . When the valve plate 400 slides relative to the plate frame 210 , the valve hole 420 and the inlet port 111 can be opposite or staggered, thereby opening and closing the inlet port 111 .

[0043] Reference Figure 3 According to some embodiments of the present invention, openings are provided at both upper and lower ends of the accommodating groove 230, and the upper and lower ends of the valve plate 400 are correspondingly penetrated through the two openings. Thus, both upper and lower ends of the valve plate 400 can be grasped by the user, making it convenient for the user to operate the valve plate 400 to open and close the entrance 111.

[0044] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, a step 214 is provided on the surface of the plate frame 210 protruding toward the dust bag body 100, the step 214 is inserted into the entrance port 111, and the first avoidance hole 211 is penetrated through the step 214. The above arrangement can ensure that the plate frame 210 can be accurately installed on the dust bag body 100. In addition, it can also prevent the side wall of the entrance port 111 from blocking dust and other debris from entering the accommodating cavity 110.

[0045] According to some embodiments of the present invention, the valve plate 400 is made of paper, and the cover plate 220 is made of paper. Therefore, the plate frame 210, the valve plate 400, and the cover plate 220 are all made of paper materials, and the plastic film 300 itself is thin and uses less material. Compared with the valve plate 400, the cover plate 220, and the plate frame 210 made of plastic, the dust bag provided by the present invention has obvious cost advantages and environmental advantages, that is, the dust bag provided by the present invention is low in cost and environmentally friendly.

[0046] In the specific implementation process, the cover plate 220 and the plate frame 210 can be connected in various ways. For example, the cover plate 220 and the plate frame 210 are bonded together, the cover plate 220 and the plate frame 210 can also be riveted together by a rivet structure, or the cover plate 220 and the plate frame 210 are snap-fitted by a snap-fit ​​structure.

[0047] It should be noted that the above-mentioned valve plate 400 can also be slidably set on the cover plate 220 in other ways. For example, the left and right ends of the plate frame 210 are folded with folded edges, and the ends of the folded edges are bonded to the plate frame 210, so that the folded edges and the plate frame 210 form a slideway. The left and right ends of the valve plate 400 are provided with strip holes, and the strip holes are used to avoid the ends of the folded edges. The outer wall of the strip holes is located in the slideway. Therefore, the valve plate 400 can slide relative to the plate frame 210, and the sliding range of the valve plate 400 is limited by the folded edges.

[0048] Reference Figures 1 to 4According to some embodiments of the utility model, a sealing ring 500 is provided at the first avoidance hole 211, and the sealing ring 500 abuts against the valve plate 400. Thus, on the one hand, the resistance of the valve plate 400 when sliding is increased, which plays a role in damping and positioning the valve plate 400. On the other hand, a seal is formed between the valve plate 400 and the plate frame 210, thereby reducing the leakage of dust, air, etc. inside the accommodating cavity 110 of the dust bag body 100.

[0049] According to a second aspect of the present invention, a cleaning device includes the above-mentioned dust bag. By using the above-mentioned dust bag, the connection strength between the board frame made of cardboard and the dust bag body can be improved, the strength of the board frame can be increased, and the situation where the board frame 210 made of cardboard is separated from the dust bag body 100 can be effectively reduced, thereby ensuring the normal use of the dust bag.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
