Technical Field

[0001] This utility model relates to the field of ventilation duct technology, and in particular to a multi-duct ventilation device that is easy to clean. Background Technology

[0002] As an important component of the ventilation system, the performance and reliability of multi-duct exhaust systems are directly related to indoor air quality and equipment operating efficiency. However, traditional multi-duct exhaust systems often face many problems during long-term use, which not only affect the normal operation of the system but may also cause safety hazards.

[0003] Traditional multi-duct exhaust systems often prioritize exhaust efficiency and structural strength, neglecting the need for later maintenance and cleaning. The ducts are complex and narrow, making manual cleaning difficult, inefficient, and posing certain safety risks. Furthermore, while some exhaust systems are equipped with filters to block impurities, the filter placement is often unreasonable, requiring the entire system or some key components to be disassembled for replacement, which is cumbersome and increases safety hazards. Utility Model Content

[0004] The multi-duct exhaust device proposed in this utility model is easy to clean and solves the problems of inconvenient duct cleaning and unreasonable filter design and difficult replacement and maintenance of existing multi-duct exhaust devices.

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

[0006] A multi-duct exhaust device that is easy to clean includes an exhaust device body, with buckles fixedly connected to both sides of the exterior of the exhaust device body, and a filter box provided in the middle of the buckles. The filter box contains a replaceable filter screen, and an air duct is fixedly connected to the exterior of the filter box. A cleaning mechanism is provided inside the air duct.

[0007] The cleaning mechanism includes a chute, a lead screw, a cleaning frame, and a scraper. The chute is located inside the air duct, and the lead screw is located inside the chute. A cleaning frame matching the chute is located outside the lead screw, and a scraper is movably connected to the outside of the cleaning frame. The scraper is driven to reciprocate through the lead screw to clean the inside of the air duct.

[0008] Preferably, the filter box has slides on both sides inside, and a movable frame is provided inside the slide. The top of the movable frame is fixedly connected to a limiting plate that matches the slide, forming a movable connection.

[0009] Preferably, the movable frame has a through groove inside, and a filter screen is snapped into the through groove. Multiple sets of snap-fit ​​grooves are provided on both sides of the through groove inside the movable frame, and snap-fit ​​buckles matching the snap-fit ​​grooves are provided on both sides of the filter screen outside.

[0010] Preferably, the bottom of the filter box is provided with multiple sets of threaded holes, and a cover plate is provided on the outside of the threaded holes, the cover plate being bolted to the inside of the threaded holes.

[0011] Preferably, the cleaning mechanism further includes a limiting groove, a limiting block, a rotating shaft, an adjusting groove, an arc-shaped baffle, a fixing groove, a drive motor, an annular sealing plate, a cleaning port, and a sealing cover. A fixing groove is provided above the air duct, and a drive motor is fixedly installed inside the fixing groove. The output end of the drive motor is connected to a lead screw. An annular sealing plate is sleeved on the outside of the air duct, and the annular sealing plate is located outside the drive motor.

[0012] Preferably, the other end of the air duct is provided with a limiting groove inside, and the bottom of the cleaning frame is connected to a limiting block that matches the limiting groove in a movable connection. A cleaning port is provided below the side end of the air duct, and a sealing cap is connected to the outside of the cleaning port by a thread.

[0013] Preferably, an arc-shaped baffle is fixedly connected to the side of one end of the cleaning frame, and an adjustment groove is provided inside both sides of the other end of the cleaning frame, and a scraper is installed inside the adjustment groove via a rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This easy-to-clean multi-duct exhaust device has a cleaning mechanism inside the duct. The cleaning frame and the internal movable scraper can move flexibly along the inner wall of the duct by the drive motor to drive the lead screw to rotate, effectively scraping off the attached dust and stains. The scraper material must have good wear resistance and elasticity to ensure the cleaning effect and avoid damage to the duct wall. At the same time, the setting of the arc baffle and the scraper being installed in the adjustment groove through the rotating shaft prevent the scraper from pushing the dust back during the reverse rotation of the drive motor, which would affect the cleaning effect and cause secondary pollution.

[0016] 2. Filter boxes are installed on both sides of the exterior of the exhaust device body. The filter boxes are equipped with removable filter screens, which is an effective means to prevent impurities from entering the exhaust device body. The filter screens are connected by snaps. The cover plate is removed by bolts. The movable frame falls along the inner wall of the slide under the action of gravity, which makes it easy for users to remove the filter screens for cleaning or replacement without disassembling the entire device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-7 This utility model provides a technical solution: a multi-duct exhaust device that is easy to clean, including an exhaust device body 1, with buckles 2 fixedly connected to both sides of the exhaust device body 1, and a filter box 3 set in the middle of the buckles 2. A replaceable filter screen 4 is set inside the filter box 3. The filter screen 4 is usually made of corrosion-resistant and easy-to-clean polymer fiber mesh material to improve its durability and cleaning effect. An air duct 5 is fixedly connected to the outside of the filter box 3.

[0028] Reference Figure 1 , Figure 7The filter box 3 has slides 10 on both sides inside, and a movable frame 11 is provided inside the slides 10. The top of the movable frame 11 is fixedly connected to a limiting plate 12 that matches the slide 10. The movable frame 11 has a through groove 13 inside, and a filter screen 4 is snapped into the through groove 13. The filter screen 4 can effectively capture fine particles and microorganisms, ensuring the air quality entering the exhaust device body 1. Multiple sets of snap-fit ​​grooves 14 are provided on both sides of the through groove 13 inside the movable frame 11, and snap-fit ​​buckles 15 that match the snap-fit ​​grooves 14 are provided on both sides of the filter screen 4 outside. The bottom of the filter box 3 has multiple sets of threaded holes 16, and a cover plate 17 is provided on the outside of the threaded holes 16. The cover plate 17 is connected to the inside of the threaded holes 16 by bolts 18.

[0029] In practical implementation, for easy-to-clean multi-duct exhaust devices, when replacing the filter screen 4, first unscrew the bolt 18 from the threaded hole 16, then remove the cover plate 17. Simultaneously, under gravity, the movable frame 11 slowly falls along the inner wall of the slide 10. Because the top of the movable frame 11 is fixedly connected to the limiting plate 12, it limits the falling movable frame 11, effectively preventing it from detaching from the inner wall of the slide 10. Next, pull down the filter screen 4 forcefully. Once the snap-fit ​​buckle 15 on the top of the filter screen 4 is separated from the snap-fit ​​groove 14 inside the movable frame 11, the filter screen 4 can be easily removed from the through groove 13 for cleaning and maintenance. Then, a new filter screen 4 can be inserted. Similarly, the filter screen 4 can be snapped into the movable frame 11 through the snap-fit ​​buckle 15 and the snap-fit ​​groove 14. Then, the movable frame 11 can be manually raised into the slide rail 10, and the cover plate 17 can be tightened with the bolt 18. Through the above operations, the disassembly and maintenance of the filter screen 4 is more convenient, which helps to extend the service life of the equipment.

[0030] Example 2

[0031] Reference Figure 2 , Figure 3 This embodiment is an optimization based on Embodiment 1. A cleaning mechanism is provided inside the air duct 5. The cleaning mechanism includes a slide 6, a lead screw 7, a cleaning frame 8, and a scraper 9. The slide 6 is provided inside the air duct 5, and the lead screw 7 is provided inside the slide 6. A cleaning frame 8 matching the slide 6 is provided on the outside of the lead screw 7. The interface between the slide 6 and the cleaning frame 8 is elongated, which helps to reduce the entry of dust. At the same time, under the exhaust action of the exhaust device body 1, it can prevent dust from adhering to the outside of the lead screw 7. The scraper 9 is movably connected to the outside of the cleaning frame 8, and the scraper 9 is driven by the lead screw 7 to reciprocate, cleaning the inside of the air duct 5.

[0032] Reference Figure 5 , Figure 4The cleaning mechanism also includes a limiting groove 19, a limiting block 20, a rotating shaft 21, an adjusting groove 22, an arc-shaped baffle 23, a fixing groove 24, a drive motor 25, an annular sealing plate 26, a cleaning port 27, and a sealing cover 28. A fixing groove 24 is provided above the air duct 5, and a drive motor 25 is fixedly installed inside the fixing groove 24. The output end of the drive motor 25 is connected to the lead screw 7. An annular sealing plate 26 is sleeved on the outside of the air duct 5, and the annular sealing plate 26 is located outside the drive motor 25. The annular sealing plate 26 effectively prevents air leakage and dust intrusion.

[0033] Reference Figure 2 , Figure 6 The other end of the air duct 5 has a limiting groove 19 inside, and the bottom of the cleaning frame 8 is connected to a limiting block 20 that matches the limiting groove 19 in a movable connection. The side end of the air duct 5 has a cleaning port 27 below, and the outside of the cleaning port 27 is connected to a sealing cap 28 by a thread. An arc-shaped baffle 23 is fixedly connected to the side of one end of the cleaning frame 8, and the other end of the cleaning frame 8 has an adjustment groove 22 inside both sides, and a scraper 9 is installed inside the adjustment groove 22 through a rotating shaft 21. The scraper 9 is usually made of a material with good wear resistance and elasticity, which can ensure the cleaning effect and avoid damage to the air duct wall.

[0034] In practical implementation, the multi-duct exhaust system, which is easy to clean, is activated by starting the drive motor 25 when cleaning. The drive motor 25 can be equipped with a reducer (not shown in the figure) to drive the lead screw 7 to rotate. Since the lead screw 7 is embedded in the slide groove 6 and is movably connected, it rotates inside the slide groove 6, thereby realizing the reciprocating motion of the cleaning frame 8 along the inner wall of the slide groove 6. At the same time, the limiting block 20 at the other end of the cleaning frame 8 also moves synchronously along the inner wall of the limiting groove 19. Since one end of the cleaning frame 8 is fixedly connected to the arc-shaped baffle 23, and the scraper 9 at the other end is installed in the adjusting groove 22 inside the cleaning frame 8 through the rotating shaft 21, when the drive motor 25 drives clockwise, the cleaning frame 8 and the scraper 9 are limited by the arc-shaped baffle 23. The scraper 9, which moves flexibly along the inner wall of the duct 5, effectively scrapes away the attached dust and dirt. When the drive motor 25 drives counterclockwise, the scraper 9 inside the cleaning frame 8 rotates inside the adjustment groove 22 via the rotating shaft 21, reducing the scraper 9 from pushing the dust back and avoiding secondary pollution inside the duct 5. Then, the inner sealing cover 28 of the cleaning port 27 is unscrewed, and the dust and impurities collected by the scraper 9 are discharged outside the duct 5 through the cleaning port 27. Then, the sealing cover 28 is tightened to ensure that the cleaning port 27 is completely sealed when not in use, preventing air leakage and dust intrusion. Through the above operations, the reciprocating scraper 9 ensures the cleanliness of the inside of the duct 5 and also ensures that the exhaust device is always in the best working condition.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
