Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically a ventilation device for a packaging warehouse. Background Technology

[0002] Packaging warehouses typically store large quantities of packaging materials and finished products. These items are highly sensitive to environmental conditions. Good ventilation can regulate the temperature and humidity within the warehouse, preventing excessive humidity from causing packaging materials to become damp and moldy, thus affecting the quality and performance of the packaging. It can also prevent safety hazards such as fires caused by excessive temperatures or accelerate the aging of packaging materials. Furthermore, ventilation ensures fresh air within the warehouse, reduces the accumulation of odors and harmful gases, provides a healthy and comfortable working environment for warehouse staff, improves work efficiency, and protects the health of employees. However, existing ventilation systems rely on bolted filters, which are prone to rust over time and are difficult to disassemble and clean. Additionally, most existing ventilation systems are designed to be kept open continuously, making them unable to be shut off during severe weather conditions such as strong winds, heavy rain, or blizzards. Rainwater and snowflakes can then enter the warehouse through the pipes, damaging items or affecting the indoor environment. To address these issues, a new type of ventilation system for packaging warehouses is needed.

[0003] Existing ventilation systems for packaging warehouses suffer from problems such as inconvenient quick disassembly and cleaning of filters and inability to shut down the ventilation system during operation. Therefore, there is an urgent need for a new ventilation system for packaging warehouses. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a ventilation device for packaging warehouses, so as to solve the problems that existing ventilation devices for packaging warehouses are inconvenient to quickly disassemble and clean the filter screen and cannot be turned off during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device for a packaging warehouse, comprising a ventilation duct body, a fixing plate installed on the side wall of the ventilation duct body, a filter screen installed on the inner wall of the fixing plate, a limit spring installed on the inner wall of the filter screen, and a limit lever installed on the outer wall of the limit spring.

[0006] A sealing plate is installed on the inner wall of the ventilation duct, and an adjustment handle is installed on the top of the sealing plate.

[0007] A connecting sleeve is installed on the side of the ventilation duct away from the fixed plate. An air suction groove is opened on the side wall of the connecting sleeve. A protective sleeve is installed on the side wall of the connecting sleeve. A fan is installed on the inner wall of the protective sleeve. Fan blades are installed on the outer wall of the fan.

[0008] Preferably, the inner wall of the fixing plate is designed with openings, and the filter screen is inserted into the fixing plate.

[0009] Preferably, the limiting rod forms a telescopic structure with the filter screen through a limiting spring, and the limiting rod is engaged with the fixing plate.

[0010] Preferably, the sealing plate is movably connected to the ventilation duct body, and the outer diameter of the sealing plate matches the inner diameter of the ventilation duct body.

[0011] Preferably, the connecting sleeve is threaded to the ventilation pipe body, and the air suction grooves are arranged in a ring array with the central axis of the connecting sleeve as the center.

[0012] Preferably, the fan is welded to the connecting sleeve, and the fan blades form a rotating structure through the fan and the connecting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a fixed plate, filter screen, limiting spring, and limiting lever. Traditional ventilation devices mainly fix the filter screen with bolts, which is prone to rust after long-term use and is not easy to remove and clean. This utility model presses the limiting lever inward and then inserts the limiting lever into the fixed plate. At this time, the limiting lever is pushed out by the elastic force of the limiting spring, so that the limiting lever is locked and fixed with the fixed plate, making it easier to disassemble and clean.

[0015] 2. This utility model features a sealing plate and an adjusting handle. Existing ventilation devices are mostly set to be open during use. When encountering severe weather such as strong winds, heavy rain, or blizzards, they cannot be closed. Rainwater, snowflakes, etc. enter the room through the pipes, damaging indoor items or affecting the indoor environment. This utility model controls the opening and closing of the ventilation pipe by rotating the adjusting handle to drive the sealing plate to rotate, thus making it more practical.

[0016] 3. This utility model uses a connecting sleeve, air intake groove, protective sleeve, fan and fan blades to connect the connecting sleeve to the ventilation pipe body by thread. Then, the fan is started to drive the fan blades to rotate, drawing outdoor air into the room and accelerating air circulation. Compared with traditional natural ventilation devices, the ventilation effect is better. Attached Figure Description
