Description

Technical Field

[0001] This utility model belongs to the field of dust bag technology, and specifically relates to a dust bag structure that can be sealed. Background Technology

[0002] Dust bags, as a type of filtration device used to capture and collect solid particles, are widely used in household vacuum cleaners, industrial dust removal equipment, air purification systems, and other fields. Their performance directly affects cleaning efficiency, equipment energy consumption, and environmental safety.

[0003] According to a dust bag structure disclosed in Chinese Patent Publication No. CN219922365U, a dust bag body, a card plate assembly, and a disassembly structure are provided. A card plate assembly with a hole is provided at one corner of the side wall of the dust bag body. The thickness of the card plate assembly is H, and the diameter of the first through hole is D. A disassembly structure is provided at the bottom of the dust bag body. The card plate assembly includes a first card plate, a handle, a card slot, and a second card plate that are pressed together in sequence. The second card plate is bonded to the dust bag body. The first card plate, the handle, the card slot, and the second card plate are bonded together with sealant.

[0004] However, the aforementioned devices all have drawbacks in their combination with existing dust bag structures. When dust and debris accumulate inside the dust bag to the point where it needs to be replaced, the traditional dust bag installation port generally lacks an effective quick-release structure. During disassembly, dust and debris inside the bag can easily move outward from the installation port and spill out. For example, conventional vacuum cleaner dust bags are usually only connected to the vacuum cleaner through a simple snap-fit ​​or elastic sealing ring. During disassembly, due to airflow disturbances and gravity, fine dust can easily leak from the installation gap, while larger debris may get stuck at the interface and scatter, not only contaminating the internal components of the vacuum cleaner but also causing secondary pollution to the surrounding environment and increasing the cleaning burden on users. Utility Model Content

[0005] In view of the problem that dust inside the dust bag is easily leaked due to airflow disturbance when the dust bag is disassembled in the relevant technology, this utility model proposes a dust bag structure that can be sealed to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a dust bag structure that can be sealed, including a dust bag body, a sealing mechanism at the opening of the dust bag body, an elastic switch mechanism inside the sealing mechanism, and a compression transmission mechanism at the elastic end of the elastic switch mechanism. By squeezing or releasing the squeezing transmission mechanism, the squeezing end of the squeezing transmission mechanism drives the transmission end to move, so that the transmission end drives the switching end of the elastic switch mechanism to move, so that the switching end drives the sealing end of the sealing mechanism to slide at the opening of the dust bag body.

[0007] Furthermore, the sealing mechanism includes a mounting plate, which is fixedly connected to the opening of the dust bag body. The mounting plate has a dust inlet hole on its surface corresponding to the opening of the dust bag body. The mounting plate also has a snap-fit ​​groove on its surface. A cardboard is slidably connected inside the mounting plate. A sealing plate is fixedly connected to one end of the cardboard. The sealing plate is slidably connected to the dust inlet hole. A pull groove is provided on the surface of the cardboard.

[0008] Furthermore, the elastic switch mechanism includes a limiting rod, which is fixedly connected inside the mounting plate. A movable plate is slidably connected to the surface of the limiting rod, which is fixedly connected to one side of the cardboard. A spring is fixedly connected to one end of the movable plate, and one end of the spring is fixedly connected inside the mounting plate. The spring is sleeved on the surface of the limiting rod.

[0009] Furthermore, the extrusion transmission mechanism includes a lever, which is rotatably connected inside the mounting plate. One end of the lever is fixedly connected to an arc-shaped tooth, and a pinion meshes with the surface of the arc-shaped tooth. The pinion is rotatably connected inside the mounting plate.

[0010] Furthermore, a large gear is fixedly connected to one end of the small gear, a rack meshes with the surface of the large gear, the rack is slidably connected inside the mounting plate, and one end of the rack is fixedly connected to the surface of the movable plate.

[0011] Furthermore, a sealing strip is embedded inside the mounting plate, and the sealing strip is located at the connection between the mounting plate and the sealing plate.

[0012] Furthermore, a mounting frame is fixedly connected inside the dust bag body, and an elastic filter is fixedly connected inside the mounting frame.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes a three-stage mechanical linkage of compression, transmission, and sealing to achieve automatic isolation during installation and disassembly of the dust bag body and dust removal equipment. This effectively prevents dust leakage, secondary pollution, and reduces the cleaning burden on users.

[0014] 2. In this invention, when vacuuming, the dust falling to the bottom of the dust bag exerts pressure on the elastic filter, causing it to sink slightly. The impact force is buffered by the elastic deformation, preventing the dust from being compacted due to instantaneous impact. When vacuuming stops, the negative pressure disappears, and the elastic filter returns to its original shape and rebounds upward, which can slightly lift the dust accumulated at the bottom and break up the loose clumps that have formed. This structure effectively prevents dust from clumping inside the dust bag through the synergistic effect of elasticity and mechanical movement, thereby improving the dust holding efficiency of the dust bag.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-6 As shown, this utility model is a dust bag structure that can be sealed, including a dust bag body 1, a sealing mechanism 2 is provided at the opening of the dust bag body 1, an elastic switch mechanism 3 is provided inside the sealing mechanism 2, and a compression transmission mechanism 4 is provided at the elastic end of the elastic switch mechanism 3. By squeezing or releasing the squeezing transmission mechanism 4, the squeezing end of the squeezing transmission mechanism 4 drives the transmission end to move, so that the transmission end drives the switching end of the elastic switch mechanism 3 to move, so that the switching end drives the sealing end of the sealing mechanism 2 to slide at the opening of the dust bag body 1.

[0022] When installing the dust bag body 1 with the dust removal equipment, press the compression transmission mechanism 4 to move the compression end of the compression transmission mechanism 4, which in turn drives the switching end of the elastic switch mechanism 3 to move, so that the switching end drives the sealing end of the sealing mechanism 2 to open at the opening of the dust bag body 1; when disassembling, the compression transmission mechanism 4 is released, and the elastic end of the elastic switch mechanism 3 drives the switching end to move, which in turn drives the sealing end of the sealing mechanism 2 to close at the opening of the dust bag body 1.

[0023] When the dust bag body 1 is installed with the dust removal equipment, pressing the compression transmission mechanism 4 causes the compression end to move, which in turn drives the switching end of the elastic switch mechanism 3 to move, so that the sealing end of the sealing mechanism 2 automatically opens at the opening of the dust bag body 1. When disassembling, the compression transmission mechanism 4 is released, and the elastic end of the elastic switch mechanism 3 resets, driving the switching end to move in the opposite direction, causing the sealing end of the sealing mechanism 2 to automatically close at the opening. This design achieves automatic isolation during installation and disassembly through a three-stage mechanical linkage of compression, transmission, and sealing, effectively preventing dust leakage and reducing the user's cleaning burden.

[0024] In one embodiment, the sealing mechanism 2 includes a mounting plate 201, which is fixedly connected to the opening of the dust bag body 1. The mounting plate 201 has a dust inlet hole 202 corresponding to the opening of the dust bag body 1 on its surface. The mounting plate 201 also has a snap-fit ​​groove 203 on its surface. A cardboard 204 is slidably connected inside the mounting plate 201. A sealing plate 205 is fixedly connected to one end of the cardboard 204. The sealing plate 205 is slidably connected to the dust inlet hole 202. A pull groove 206 is provided on the surface of the cardboard 204. A sealing strip 207 is embedded inside the mounting plate 201 and is located at the connection between the mounting plate 201 and the sealing plate 205. An mounting frame 208 is fixedly connected inside the dust bag body 1, and an elastic filter 209 is fixedly connected inside the mounting frame 208.

[0025] The mounting plate 201 is installed inside the dust collection equipment via the snap-fit ​​groove 203. During use, it connects to the opening of the dust bag body 1 through the ash inlet hole 202, allowing dust to enter the dust bag body 1 through the ash inlet hole 202 for dust collection. When the ash inlet hole 202 needs to be opened or closed, the sliding pull groove 206 causes the cardboard 204 to move the sealing plate 205 inside the mounting plate 201, thereby opening and closing the ash inlet hole 202. Then, the sealing strip 207 seals the sealing plate 205 and the mounting plate 201. When vacuuming, when dust falls to the bottom of the dust bag body 1, the elastic filter 209 will sink slightly due to pressure, buffering the impact force through deformation and reducing the impact force of the dust being compacted. When vacuuming stops, the negative pressure disappears, and the elastic filter 209 rebounds, which can slightly lift the dust at the bottom of the dust bag body 1, breaking up some of the loose dust clumps that have formed.

[0026] In one embodiment, the elastic switch mechanism 3 includes a limiting rod 301, which is fixedly connected inside the mounting plate 201. A movable plate 302 is slidably connected to the surface of the limiting rod 301. The movable plate 302 is fixedly connected to one side of the cardboard 204. A spring 303 is fixedly connected to one end of the movable plate 302. One end of the spring 303 is fixedly connected inside the mounting plate 201. The spring 303 is sleeved on the surface of the limiting rod 301.

[0027] The spring 303 drives the movable plate 302 to slide inside the mounting plate 201, while the limiting rod 301 limits the movement position of the movable plate 302, so that the movable plate 302 drives the cardboard 204 to move.

[0028] In one embodiment, the extrusion transmission mechanism 4 includes a lever 401, which is rotatably connected inside the mounting plate 201. One end of the lever 401 is fixedly connected to an arc-shaped tooth 402, and a pinion 403 meshes with the surface of the arc-shaped tooth 402. The pinion 403 is rotatably connected inside the mounting plate 201, and one end of the pinion 403 is fixedly connected to a large gear 404. A rack 405 meshes with the surface of the large gear 404, and the rack 405 is slidably connected inside the mounting plate 201. One end of the rack 405 is fixedly connected to the surface of the moving plate 302.

[0029] The mounting plate 201 is installed inside the dust removal equipment via the snap-fit ​​groove 203. The dust removal equipment then presses one end of the lever 401, causing the other end of the lever 401 to rotate the arc-shaped tooth 402. The arc-shaped tooth 402 then drives the pinion 403 to rotate, which in turn drives the large gear 404 to rotate. The large gear 404 then drives the rack 405 to slide inside the mounting plate 201, causing the rack 405 to drive the moving plate 302 to compress the spring 303. This causes the moving plate 302 to move the cardboard 204, which in turn moves the cardboard 204. The movable sealing plate 205 moves inside the mounting plate 201, thereby opening the ash inlet hole 202. When the device is disassembled, one end of the lever 401 is released, and the moving plate 302 is reset by the spring 303. The moving plate 302 moves the cardboard 204 and the sealing plate 205 inside the mounting plate 201, thereby closing the ash inlet hole 202. This resets the rack 405, pinion 403, arc tooth 402, and lever 401.

[0030] Through the above technical solution, 1. The mounting plate 201 is installed inside the dust removal equipment via the snap-fit ​​groove 203, causing the dust removal equipment to press one end of the lever 401, causing the other end of the lever 401 to drive the arc-shaped tooth 402 to rotate, causing the arc-shaped tooth 402 to drive the pinion 403 to rotate, thereby causing the pinion 403 to drive the large gear 404 to rotate, causing the large gear 404 to drive the rack 405 to slide inside the mounting plate 201, causing the rack 405 to drive the moving plate 302 to compress the spring 303, causing the moving plate 302 to move the cardboard 204, thus... The cardboard 204 moves the sealing plate 205 inside the mounting plate 201, thereby opening the ash inlet hole 202. When the device is disassembled, one end of the lever 401 is released, and the moving plate 302 is reset by the spring 303. The moving plate 302 moves the cardboard 204 and the sealing plate 205 inside the mounting plate 201, thereby closing the ash inlet hole 202. This resets the rack 405, pinion 403, arc tooth 402, and lever 401.

[0031] 2. During vacuuming, the dust falling to the bottom of the dust bag body 1 exerts pressure on the elastic filter 209, causing it to sink slightly and buffer the impact force through elastic deformation, preventing the dust from being compacted due to instantaneous impact; when vacuuming stops, the negative pressure disappears, and the elastic filter 209 recovers its deformation and rebounds upward, which can slightly bounce up the dust accumulated at the bottom and break up the loose clumps that have formed; this structure effectively prevents dust from clumping inside the dust bag body 1 through the synergistic effect of elasticity and mechanical movement, thereby improving the dust holding efficiency of the dust bag body 1.
