Description

Technical Field

[0001] This utility model belongs to the field of vegetable planting technology, specifically relating to a ventilation device for vegetable planting greenhouses. Background Technology

[0002] Currently, there are various types of ventilation devices used in vegetable greenhouses. One common device involves installing vents in the greenhouse walls and mounting fans to promote air circulation. However, these devices still have some problems that need to be addressed in their design and use. Firstly, the exterior surfaces of the ventilation devices are usually fitted with louvers, whose main function is to prevent rainwater, dust, insects, etc., from entering the ventilation system, thus protecting critical components such as the fans from damage. However, in existing technology, the louvers are often fixed to the outer wall of the greenhouse. While this design provides some protection, it also makes cleaning inconvenient. Because the louvers are constantly exposed to the external environment, they easily accumulate dust and debris. If not cleaned promptly, this not only affects the appearance of the ventilation device but, more importantly, obstructs airflow. On the other hand, inside the greenhouse, the air temperature, humidity and gas composition may vary at different heights. For example, the air near the vegetable canopy may have higher humidity and lower carbon dioxide concentration due to plant transpiration. If the fan height is fixed, it may not be able to effectively exhaust the air near the canopy, nor can it evenly introduce fresh air from outside into all heights inside the greenhouse, thus affecting the ventilation effect and hindering the healthy growth of vegetables. Utility Model Content

[0028] This specific embodiment is a ventilation device for vegetable greenhouses, and its structural diagram is shown below. Figure 1 As shown, it includes a housing 1, a louvered frame 2 and a support rod 3. The support rod 3 is symmetrically distributed on both sides of the housing 1. The housing 1 has a ventilation fan 7 inside, and the housing 1 is equipped with a louvered frame 2 corresponding to the ventilation fan 7.

[0029] Reference Figure 2 , Figure 4 The louvered frame 2 has protruding locking blocks 9 on both outer walls. The outer casing 1 has mounting grooves 8 for installing the louvered frame 2, which is then embedded within it. A support base plate 4 is connected below the support rod 3, and the support base plate 4 and support rod 3 are detachably connected. A locking groove 6 is formed on the inner wall of the mounting groove 8, and the locking blocks 9 are adapted to the locking groove 6. A toggle block 5 is slidably mounted on the bottom surface of the louvered frame 2, and a spring 13 is connected to the toggle block 5. A horizontal sliding groove is formed on the bottom surface of the louvered frame 2 for sliding the toggle block 5, and the end of the spring 13 away from the toggle block 5 is fixedly connected to the inner wall of the sliding groove. The locking blocks 9 are fixedly connected to the toggle block 5 and move synchronously with it.

[0030] Reference Figure 3 A combined rod 11 is provided between the support rod 3 and the support base plate 4. The bottom end face of the support rod 3 has a protruding connector 10, and the bottom end face of the combined rod 11 also has a connector 10. The upper surface of the combined rod 11 has a groove for fitting the connector 10. The upper surface of the support base plate 4 has a mounting head 12, which also has a groove inside. The connector 10 is fitted into the groove and inserted, and is fixed by bolts.

[0031] Working principle: The louver frame assembly and disassembly mechanism allows the louver frame 2 to be quickly fixed in place by the locking blocks 9 on both sides and the locking slots 6 within the mounting groove 8 of the outer casing 1. The user slides the toggle block 5 within the slide groove, compressing the spring 13 to disengage the locking blocks 9 from the locking slots 6, allowing the louver frame 2 to be removed from the mounting groove 8 for easy cleaning and maintenance. After cleaning, the louver frame 2 is re-inserted into the mounting groove 8, and the locking blocks 9 automatically engage with the locking slots 6 under the reset action of the spring 13, completing the installation.

[0032] The support rod height adjustment mechanism allows for height adjustment between the support rod 3 and the support base plate 4 via a combination rod 11. The connector 10 at the bottom of the support rod 3 is inserted into the groove at the top of the combination rod 11, and the connector 10 at the bottom of the combination rod 11 is then inserted into the groove of the mounting head 12 on the support base plate 4. The connection is achieved by tightening bolts. Depending on the ventilation requirements at different heights inside the greenhouse, users can increase or decrease the number of combination rods 11 to flexibly adjust the height of the ventilation device, ensuring airflow covering key areas such as the canopy. After the ventilation fan 7 is activated, outside air enters the outer shell 1 through the gaps in the louvered frame 2, is accelerated by the ventilation fan 7, and then delivered into the greenhouse, achieving air circulation. The louvered frame 2's blade design blocks rainwater, dust, and insects while maintaining ventilation efficiency.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
