Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment, and in particular to a convenient ventilation device. Background Technology

[0002] In modern building and industrial environments, ventilation systems play a vital role. They not only regulate indoor air quality but also effectively control temperature and humidity, providing a comfortable working and living environment for people, while also contributing to the normal operation and preservation of equipment.

[0003] Existing ventilation systems typically include fans and ventilation ducts. However, current ventilation systems cannot be placed on the ground or suspended at a height depending on the ventilation location. When ventilation systems need to be installed at a height, additional brackets or other tools are usually required to erect the ventilation system at a height. After fixed installation, it is inconvenient to disassemble and adjust the installation position of the ventilation system at will, making it inflexible and inconvenient to use.

[0004] Therefore, it is necessary to design a portable ventilation device that can be placed on the ground or suspended high up depending on the ventilation location, so as to adapt to different ventilation needs and be flexible and convenient to use. Utility Model Content

[0005] To overcome the shortcomings of existing ventilation devices, which typically require additional supports or other tools to erect them at a high place, making it inconvenient to disassemble and adjust their installation position after installation, and lacking flexibility and convenience, this utility model provides a portable ventilation device that can be placed on the ground or suspended at a high place depending on the ventilation location, making it easy to adapt to different ventilation needs and providing flexibility and convenience in use.

[0006] A convenient ventilation device includes a main frame, fans, hooks, telescopic covers, an outer frame, fixed cylinders, support frames, adjustment knobs, and rollers. Six fans are connected inside the main frame. Hooks are connected to the upper sides of the front and rear of the main frame. Telescopic covers are connected to the left and right sides of the main frame. The outer frame is connected to the side of the telescopic covers that are far apart from each other. Fixed cylinders are connected to the lower sides of the front and rear of the outer frame. Support frames are slidably connected to the fixed cylinders. Adjustment knobs are threadedly connected to the lower parts of the fixed cylinders. The adjustment knobs are in contact with the adjacent support frames. Rollers are rotatably connected to the lower parts of the support frames.

[0007] Optionally, it also includes a handle, which is connected to the upper side of the middle of the main frame.

[0008] Optionally, the telescopic covers are all corrugated structures.

[0009] Optionally, the adjustment knobs are all equipped with anti-slip textures.

[0010] Optionally, it also includes a filter screen, with the filter screen connected to the outer frame.

[0011] Optionally, it also includes a sleeve, a perforated sliding rod, a sliding frame, and a spring. Sleeves are connected to both the front and rear sides of the main frame. Perforated sliding rods are slidably connected to both the left and right sides of the sleeves. Two left and right sliding frames are slidably connected to both the front and rear sides of the main frame. Each sliding frame is engaged with an adjacent perforated sliding rod. Springs are connected between the upper and lower parts of each sliding frame and the main frame.

[0012] The beneficial effects of this utility model are: 1. By adjusting the support frame up and down, this utility model drives the main frame to move up and down, thereby adjusting the height of the fan. When it is necessary to install this device at a high place, the hook can be directly hung at a high place, which achieves the effect of being able to be placed on the ground or hung at a high place according to the ventilation position, which is convenient to adapt to different ventilation needs and is flexible and convenient to use.

[0013] 2. This utility model retracts the telescopic cover by moving the support frame upwards, then moving the sliding frame outwards to stretch the spring, and then moving the perforated sliding rod inwards. Subsequently, the sliding frame is released, the spring returns to its original position, and the sliding frame moves back to its original position to engage with the perforated sliding rod. Then, the device can be carried by holding the handle. This achieves the effect of conveniently retracting the device and making it easy to carry and store. Attached Figure Description

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0021] A convenient ventilation device, such as Figures 1-4As shown, the system includes a main frame 1, a handle 2, a fan 3, a hook 4, a telescopic cover 5, an outer frame 6, a filter screen 7, a fixing cylinder 8, a support frame 9, an adjustment knob 10, rollers 11, a sleeve 12, a perforated sliding rod 13, a sliding frame 14, and a spring 15. A handle 2 is connected to the upper middle part of the main frame 1. Six fans 3 are connected inside the main frame 1. Hooks 4 are connected to the upper front and rear parts of the main frame 1. Telescopic covers 5 are connected to both the left and right sides of the main frame 1. The telescopic covers 5 have a corrugated structure for easy extension and retraction. An outer frame 6 is connected to the side of the telescopic covers 5 that is furthest apart. Filter screens 7 are connected to the outer frame 6. Filter screens 7 are connected to the lower front and rear parts of the outer frame 6. A fixed cylinder 8 is connected to the main frame 1. Each fixed cylinder 8 is slidably connected to a support frame 9. Each fixed cylinder 8 is threadedly connected to an adjustment knob 10. Each adjustment knob 10 is provided with anti-slip texture for easy gripping. Each adjustment knob 10 is in contact with the adjacent support frame 9. Each support frame 9 is rotatably connected to a roller 11. Each main frame 1 is connected to a sleeve 12 on both the front and rear sides. Each sleeve 12 is slidably connected to a perforated sliding rod 13 on both the left and right sides. Each main frame 1 is slidably connected to two sliding frames 14 on both the front and rear sides. Each sliding frame 14 is engaged with the adjacent perforated sliding rod 13. Each sliding frame 14 is connected to the main frame 1 by a spring 15 on both the upper and lower parts.

[0022] When using this device, first hold the handle 2 and carry it to the area requiring ventilation, ensuring the rollers 11 contact the ground. Then, move the sliding frame 14 outwards, stretching the spring 15. Next, move the perforated sliding rod 13 outwards on the sleeve 12, extending the telescopic cover 5. Then, release the sliding frame 14, allowing the spring 15 to return to its original position, moving the sliding frame 14 back to its original position and engaging with the perforated sliding rod 13, thus limiting and fixing the telescopic cover 5. Next, loosen the adjustment knob 10 and move the support frame 9 on the fixed cylinder 8, moving the main frame 1 up and down to adjust the height of the fan 3. After adjusting to the appropriate height, tighten the adjustment knob 10 and start the fan 3 for ventilation. During ventilation, dust and impurities are filtered through the filter screen 7 on the outer frame 6. This device can be installed at a higher location if necessary. The hook 4 can be directly hung at a high place, allowing it to be placed on the ground or hung at a high place depending on the ventilation location, making it flexible and convenient to use. When ventilation is needed in other areas, the device can be quickly moved to other areas with the help of the roller 11. When ventilation is no longer needed, turn off the fan 3, then turn and loosen the adjustment knob 10, then move the support frame 9 upwards to fold it up, then turn and tighten the adjustment knob 10, then move the sliding frame 14 outwards, stretching the spring 15, then move the perforated sliding rod 13 inwards, causing the telescopic cover 5 to retract. Then release the sliding frame 14, the spring 15 returns to its original state, and the sliding frame 14 moves back to its original position and engages with the perforated sliding rod 13. Then hold the handle 2 to carry the device, making it easy to fold up and carry and store.
