Description

Technical Field

[0001] This utility model relates to the field of filter screens, specifically to an automatic replacement device for a roller shutter type filter screen. Background Technology

[0002] Dust filters are functional materials used to intercept and adsorb suspended particulate matter in the air. They are widely used in air conditioners, air purifiers, fresh air systems and various ventilation equipment. They can reduce dust accumulation inside the equipment to extend its service life, and also reduce the concentration of particulate matter in indoor air to improve air quality.

[0003] When excessive dust accumulates on the filter, its ventilation efficiency decreases significantly, necessitating disassembly and cleaning. However, most current roller shutter filters are fixed inside the roller shaft using bolts and clamps. Both disassembly and installation require tools to tighten these bolts. Given the typically compact internal space of ventilation equipment, using tools to loosen the bolts is inconvenient, making filter removal and assembly very cumbersome and reducing efficiency.

[0004] Therefore, it is necessary to invent an automatic replacement device for a roller shutter filter to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic replacement device for a roller shutter-type filter screen. By setting a locking rod and a locking groove, the two ends of the filter screen can be quickly connected to the drive shaft and the driven shaft. The locking rod can be fixed and disassembled by the sliding engagement of the locking block with the locking hole, thus enabling quick installation and removal of the filter screen for cleaning. The complete circle formed by two sets of semi-circular limiting plates can limit the two sides of the filter screen, so that the filter screen can be neatly rolled up on the outer wall of the driven shaft and the drive shaft. This allows the filter screen to be neatly arranged at the air outlet of the ventilation equipment, so that it can give full play to its filtering effect.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1 - Figure 3 The automatic replacement device for a roller shutter type filter screen shown includes a drive shaft 1, a driven shaft 2, a filter screen 3, and a disassembly and assembly mechanism 7. A motor 4 is fixedly connected to the left end of the drive shaft 1. Both the driven shaft 2 and the inner wall of the drive shaft 1 are provided with slots 5. When the motor 4 is started, the drive shaft 1 is driven to rotate, so that the drive shaft 1 can roll up the dust-covered filter screen 3. This allows the unused filter screen 3 rolled up on the outer wall of the driven shaft 2 to enter the air vent of the ventilation equipment, so that the filter screen 3 can be replaced automatically without the need for frequent manual replacement of the filter screen 3. Both ends of the filter screen 3 are fixedly connected to the clamp rods 6. The outer wall of the clamp rods 6 is provided with a guide mechanism 8. The clamp rods 6 are engaged with the inner wall of the slot 5. The filter screen 3 can filter dust in the air.

[0018] like Figure 3 - Figure 5 As shown, the disassembly and assembly mechanism 7 includes a locking block 71, which is slidably connected to the inner wall of the locking rod 6. The inner walls of both the drive shaft 1 and the driven shaft 2 are provided with locking holes 72. By using the locking block 71 in conjunction with the locking holes 72, the locking rod 6 can be limited to the inside of the locking groove 5. The upper and lower ends of the locking block 71 are fixedly connected with guide rods 73. The inner wall of the locking rod 6 is slidably connected with a slider 74. The slider 74 is provided with a slanted groove 75. The outer wall of the guide rod 73 is attached to the inner wall of the slanted groove 75. When the slider 74 slides, the slanted groove 75 on the slider 74 pushes the guide rod 73, causing the guide rod 73 to push the locking block 71. At this time, the locking block 71 will slide on the inner wall of the locking rod 6. The side wall of the slider 74 is fixedly connected with a spring 76. The end of the spring 76 away from the slider 74 is fixedly connected to the inner wall of the locking rod 6. The elasticity of the spring 76 pushes the slider 74 to slide and reset on the inner wall of the locking rod 6.

[0019] like Figure 4 - Figure 6As shown, the guide mechanism 8 includes a limiting plate 81, which is hinged to the inner wall of the clamping rod 6. The limiting plate 81 is a semi-circular plate structure. The complete circle formed by the two sets of semi-circular limiting plates 81 can limit the two sides of the filter screen 3, preventing the filter screen 3 from deviating when the driven shaft 2 and the drive shaft 1 are winding it up. This allows the filter screen 3 to be neatly wound onto the outer wall of the driven shaft 2 and the drive shaft 1. A limiting groove 82 is provided on the outer wall of the limiting plate 81. A sliding rod 83 is slidably connected to the side wall of the clamping rod 6. A limiting rod 84 is fixedly connected to the side near the limiting plate 81. The outer wall of the limiting rod 84 is attached to the inner wall of the limiting groove 82. When the slide rod 83 slides, under the limiting action of the limiting groove 82, the limiting rod 84 will push the limiting plate 81, so that the limiting plate 81 rotates on the inner wall of the locking rod 6. A connecting rod 85 is hinged to the side wall of the slide rod 83. The end of the connecting rod 85 away from the slide rod 83 is hinged to the side wall of the slider 74. When the slider 74 slides, it can drive the slide rod 83 to slide on the side wall of the locking rod 6 in conjunction with the connecting rod 85.

[0020] The working principle of this utility model is as follows: During use, the motor 4 can be fixed inside the ventilation equipment with bolts. The drive shaft 1 rotates inside the ventilation equipment via the driven shaft 2, so that the filter screen 3 is located inside the ventilation opening of the ventilation equipment. The filter screen 3 can filter dust in the air. When too much dust adheres to the filter screen 3, reducing its ventilation effect, the motor 4 is started to drive the drive shaft 1 to rotate, causing the drive shaft 1 to roll up the dust-covered filter screen 3. At the same time, the driven shaft 2 will rotate synchronously and release the rolled-up filter screen 3 from its outer wall, thereby rolling up the dust-covered filter screen 3 and allowing the unused filter screen 3 to enter the air outlet of the ventilation equipment. This allows for automatic replacement of the filter screen 3, eliminating the need for frequent manual replacement of the filter screen 3.

[0021] When the filter screen 3 needs to be disassembled and cleaned, press the slider 74 to make it slide into the inside of the locking rod 6 and compress the spring 76. At this time, the inclined groove 75 on the slider 74 will push the guide rod 73, which will push the locking block 71. The locking block 71 will slide into the inside of the locking rod 6, so that the locking block 71 can be moved out of the inside of the locking hole 72. At this time, the limiting of the locking rod 6 can be released. Then, the locking rod 6 can be removed from the inside of the locking groove 5 to remove the filter screen 3 from the drive shaft 1 and the driven shaft 2 for cleaning.

[0022] When the cleaned filter screen 3 needs to be installed, first press the slider 74 to slide it into the inside of the locking rod 6 and compress the spring 76. At this time, the inclined groove 75 on the slider 74 will push the guide rod 73, causing the guide rod 73 to push the locking block 71. The locking block 71 will then slide into the inside of the locking rod 6 until it is fully inside. Then, lock the locking rod 6 into the slot 5, aligning the locking block 71 with the locking hole 72. At this point, release the slider 74. The elasticity of the spring 76 will push the slider 74 to slide back to its original position on the inner wall of the locking rod 6. During the sliding back process, the inclined groove 75 will push the guide rod 73, causing the guide rod 73 to push the locking block 71. The locking block 71 will then slide on the inner wall of the locking rod 6 and insert into the locking hole 72. By using the locking block 71 in conjunction with the locking hole 72, the locking rod 6 can be limited inside the slot 5, thus allowing the filter screen 3 to be installed on the outer wall of the drive shaft 1 and the driven shaft 2.

[0023] When slider 74 slides into the inside of latch 6, slider 74 pushes connecting rod 85, causing connecting rod 85 to push slide bar 83. At this time, slide bar 83 slides on the side wall of latch 6 and gradually moves away from slider 74. Simultaneously, slide bar 83 drives limiting rod 84 to move against the inner wall of limiting groove 82. Under the limiting action of limiting groove 82, limiting rod 84 pushes limiting plate 81, causing limiting plate 81 to rotate on the inner wall of latch 6. At this time, the two sets of limiting plates 81 will move away from each other so that drive shaft 1 and driven shaft 2 can separate from latch 6 through the gap between the two sets of limiting plates 81.

[0024] When slider 74 slides and resets on the inner wall of clamp 6, slider 74 pulls connecting rod 85, causing connecting rod 85 to pull slide rod 83. At this time, slide rod 83 slides on the side wall of clamp 6 and gradually approaches slider 74. Simultaneously, slide rod 83 drives limiting rod 84 to move against the inner wall of limiting groove 82. Under the limiting action of limiting groove 82, limiting rod 84 pushes limiting plate 81, causing two sets of limiting plates 81 to rotate synchronously in opposite directions and approach each other on the inner wall of clamp 6. This allows the two sets of limiting plates 81 to fit together. The complete circle formed by the two sets of semi-circular limiting plates 81 can limit the two sides of filter screen 3, preventing filter screen 3 from deviating when driven shaft 2 and drive shaft 1 are winding it up. This allows filter screen 3 to be neatly wound on the outer wall of driven shaft 2 and drive shaft 1, thus keeping filter screen 3 neat inside the air outlet of ventilation equipment and enabling it to fully exert its filtering effect.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
