Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to an indoor environmental dust removal device. Background Technology

[0002] During the renovation process, a large amount of dust and pollutants are generated. These substances not only harm the health of construction workers but can also enter the body through the respiratory system, causing various health problems. Dust removal can effectively reduce the spread of these harmful substances and protect the health of construction workers. Furthermore, materials such as wood and paint are very sensitive to dust. Dust adhering to these materials can damage their surfaces, affecting their appearance and lifespan. Dust removal can protect these materials from dust damage.

[0003] In existing technologies, cartridge dust collectors are often used for dust removal in renovated indoor spaces, mainly because of their small footprint and high filtration efficiency. However, the internal cartridges may be damaged and need replacement due to aging, contact with chemicals, or mechanical impact. Existing cartridges are mainly fixed by bolts or threads, which makes disassembly difficult. Furthermore, existing vacuum hoses are long, making them prone to contact with the ground during storage and causing rapid wear on the outer surface. Therefore, we propose an indoor environmentally friendly dust removal device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an indoor environmentally friendly dust removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An indoor environmentally friendly dust removal device includes a dust collection box. A support plate is fixedly connected to the outer wall of the dust collection box. A winding rod is fixedly connected to the top of the support plate. A suction hose is wound around the outer wall of the winding rod. A compression disc is threaded onto the top outer wall of the winding rod. One end of the suction hose is fixedly connected to the outer wall of the dust collection box. A mountain-shaped plate is fixedly connected inside the dust collection box. Four connecting rods are rotatably connected to the inner wall of the mountain-shaped plate. U-shaped rods are fixedly connected to the outer walls of the four connecting rods. Nuts are threaded onto the outer walls of the four connecting rods. A filtration mechanism is provided inside the dust collection box.

[0007] Preferably, the filtration mechanism includes two filter cartridges, the inner wall of the mountain-shaped plate is slidably connected to the outer wall of the two filter cartridges, a sealing gasket is fixedly connected to the top of each of the two filter cartridges, a baffle is fixedly connected to the dust collection box, and a collection frame is placed inside the dust collection box. The indoor dust is cleaned by setting up the filtration mechanism.

[0008] Preferably, a partition is fixedly connected inside the dust collection box, and a centrifugal fan is fixedly connected inside the dust collection box. The outer wall of the partition is provided with through holes. By setting up the centrifugal fan, negative pressure is generated in the two filter cartridges. The negative pressure in the suction hose draws external dust into the dust collection box and filters it through the two filter cartridges.

[0009] Preferably, the four U-shaped rods are arranged in pairs and pressed against the outer walls of the two filter cartridges respectively, and the U-shaped rods press and fix the outer walls of the filter cartridges.

[0010] Preferably, the outer wall of the baffle has two mating holes, and the bottom of the baffle is pressed against the top of the two sealing gaskets.

[0011] Preferably, the top of the dust collector is fixedly connected to an exhaust pipe, and the outer wall of the dust collector is hinged with a sealing door.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution allows for quick replacement of two filter cartridges by using a mountain-shaped plate, connecting rod, U-shaped rod, filter cartridge, sealing gasket, and baffle. It is simple to operate and convenient to use. The winding rod supports the wound vacuum hose, and the compression plate compresses and fixes the wound vacuum hose. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-6 As shown, an indoor environmental dust removal device is disclosed, comprising a dust collection box 1, a partition 2 fixedly connected inside the dust collection box 1, a centrifugal fan 3 fixedly connected inside the dust collection box 1, a through hole opened on the outer wall of the partition 2, the outer wall of the output end of the centrifugal fan 3 is located in the through hole, and after the blades at the output end rotate, a negative pressure environment is generated at the top of the two filter cartridges 11. A support plate 4 is fixedly connected to the outer wall of the dust collection box 1, and a winding rod 5 is fixedly connected to the top of the support plate 4. A suction hose 6 is wound around the outer wall of the winding rod 5, and the winding rod 5 winds and supports the suction hose 6.

[0024] The top outer wall of the winding rod 5 is threaded with a compression disc 7, one end of the suction hose 6 is fixedly connected to the outer wall of the dust collection box 1, and a mountain-shaped plate 8 is fixedly connected inside the dust collection box 1.

[0025] Four connecting rods 9 are rotatably connected to the inner wall of the mountain-shaped plate 8. One end of each of the four connecting rods 9 is fixedly fitted with a bearing. The outer ring of the bearing is fixedly connected to the inner wall of the mountain-shaped plate 8. U-shaped rods 10 are fixedly connected to the outer walls of the four connecting rods 9. The four U-shaped rods 10 are paired up and pressed against the outer walls of the two filter cylinders 11 respectively. The four U-shaped rods 10 are paired up and support the two filter cylinders 11 respectively. Nuts are threaded on the outer walls of the four connecting rods 9. The outer walls of the nuts are pressed against the outer walls of the mountain-shaped plate 8. The position of the connecting rods 9 is fixed by the pressing force.

[0026] The dust collector 1 is equipped with a filtration mechanism, which includes two filter cartridges 11. The inner wall of the mountain-shaped plate 8 is slidably connected to the outer wall of the two filter cartridges 11, and a sealing gasket 12 is fixedly connected to the top of each of the two filter cartridges 11.

[0027] The dust collector 1 is fixedly connected to a baffle 13. The outer wall of the baffle 13 has two mating holes. The bottom of the baffle 13 is pressed against the top of two sealing gaskets 12. The sealing gaskets 12 improve the sealing between the filter cartridge 11 and the baffle 13. A collection frame 15 is placed inside the dust collector 1 to collect dust. An electromagnetic pulse valve is installed on the top of the baffle 13. An exhaust pipe 16 is fixedly connected to the top of the dust collector 1. A sealing door 14 is hinged to the outer wall of the dust collector 1.

[0028] Working principle: When replacing the two filter cartridges 11, open the sealing door 14 to expose the two filter cartridges 11. Rotate the two bolts to prevent them from pressing against the outer wall of the triangular plate 8, thus releasing the position fixation of the connecting rod 9 and the U-shaped rod 10. Rotate the connecting rod 9 to drive the U-shaped rod 10 to rotate. After the two U-shaped rods 10 rotate relative to each other, they no longer support the outer wall of the filter cartridge 11, so that the sealing gasket 12 at the top of the filter cartridge 11 is no longer pressed against the bottom of the baffle 13. This releases the position fixation of the filter cartridge 11, forming a quick-release operation. Remove the two filter cartridges 11, and then... Slide the two new filter cartridges 11 into the two grooves of the mountain-shaped plate 8, with the top of the filter cartridges 11 positioned below the two docking holes. Rotate the four connecting rods 9 in sequence to drive the four U-shaped rods 10 to rotate. After the four U-shaped rods 10 rotate, they press against the outer walls of the two filter cartridges 11, causing the two sealing gaskets 12 at the top of the two filter cartridges 11 to press against the bottom of the baffle 13 to form a seal. Wrap the longer vacuum hose 6 around the winding rod 5, and then rotate the extrusion plate 7 to press it against the outer wall of the wound vacuum hose 6 to prevent it from unraveling.
